DETAILED DESCRIPTION
[0084] The present invention is further illustrated below in conjunction with the accompanying drawings and specific embodiments.
Embodiment 1
[0085] Illustrated in FIGS. 1-3 is an implantable urination controlling tool, which is composed of two tool handles 1, a fixing block 2 and tool handle rotation angle limiting mechanisms 3. The two tool handles 1 are, respectively, a first tool handle and a second tool handle. The tool handles 1 are each composed of a handle actuator 1.1, a connecting shaft 1.2a and a urinary tract actuator 1.3. The handle actuator 1.1 extends from an end of the connecting shaft 1.2a in an upward bending manner, and the urinary tract actuator 1.3 extends from the other end of the connecting shaft in a downward bending manner. The first tool handle and the second tool handle are arranged to be mirror-symmetric with respect to each other, and in particular, parts of the handle actuators 1.1 and the connecting shafts 1.2a are symmetric with respect to the central axis. The handle actuators 1.1 are arc-shaped structures extending towards lateral sides, terminal ends of which are bent inwards. The included angle between the plane formed by two handle actuators 1.1 and the plane formed by two connecting shafts 1.2a is an obtuse angle of 100 degrees. The handle actuators 1.1 may be toggled inwards to make the connecting shafts 1.2a rotate inwards. The word Inwards described herein refers to a direction between the two connecting shafts 1.2a, while the word Outwards corresponds to lateral sides of the connecting shafts 1.2a. The connecting shafts 1.2a of the two tool handles 1 are parallelly sleeved in communication holes 2.1 within the fixing block 2. The urinary tract actuators 1.3 of the tool handles 1 are also arc-shaped structures bent towards lateral sides, terminal ends of which are bent inwards for clamping. Specifically, they are arc-shaped structures having a substantially semi-elliptical shape, thereby conforming to the shape of the urinary tract. However, the urinary tract actuator of the first tool handle is positioned in front of the urinary tract actuator of the second tool handle. It is specified herein that along the direction of the urinary tract, the direction along which urine flows out is referred to as a front position, while the direction along which urine flows in is referred to as a back position. With regard to the present device, it can be considered that based on the connecting shaft 1.2a, the direction along which the axis of the urinary tract actuator 1.3 extends is referred to as a front position, while the direction along which the axis of the handle actuator 1.1 extends is referred to as a back position. The plane where the urinary tract actuator 1.3 of the first tool handle is positioned is different from, but parallel to, the plane where the urinary tract actuator 1.3 of the second tool handle is positioned. Moreover, the two urinary tract actuators are still symmetric in shape, but staggered with respect to each other. This solution is implanted on the urinary tract below the pubis of a male. The urinary tract actuator faces into the human body, the handle actuator faces towards the body surface of the human body, and the included angle between the handle actuator and the connecting shaft is in a range of from 90 to 120 degrees, and preferably, 100 degrees. Such a shape is designed to accommodate the physiological structure of the penis of a male.
[0086] The urinary tract actuators 1.3 are used for squeezing the urinary tract, and the urinary tract actuators 1.3 on the two tool handles 1 are arranged in a front-and-back crossed manner along the direction of the urinary tract, i.e. that the urinary tract is clamped between two urinary tract actuators 1.3. Moreover, the two urinary tract actuators 1.3 do not clamp at the same point on the urinary tract; rather, they are always in a state in which they are staggered in a front-and-back manner. It may also be considered that the connecting shafts 1.2a of the two tool handles 1 are different in length, thereby ensuring that the two urinary tract actuators 1.3 do not clamp at the same point on the urinary tract when the handle actuators 1.1 are mounted in the same plane. The middle segments of the connecting shafts 1.2a of the two tool handles are each provided with a clamping slot, the inner surface of which is the spring contact surface 1.2.1. A window 2.4 is disposed in the middle of the fixing block 2, and inner walls on two sides of the window 2.4 are provided with grooves 2.2 in communication with the communication holes 2.1. It may be considered that the grooves 2.2 are positioned on inner sides of the fixing block 2, and the window 2.4 is used for providing a motion space for the tool handles 1 to rotate. The tool handle rotation angle limiting mechanisms 3 are compressible springs 3.1, and two ends of the compressible springs 3.1 are connected with the clamping slots on the connecting shafts 1.2a in a mutually clamping manner after passing through the grooves 2.2. The compressible springs 3.1 are used for limiting the range of positive and negative included angles corresponding to the opening and closing actions that can be achieved by the two tool handles 1 when rotating. In other words, when the tool handles 1 rotate, the spring can only be stabilized in the state in which the urinary tract actuators squeeze to block the urinary tract, while other states all are process states, namely, non-stable states. When the compressible spring 3.1 is in a preset pressure state, namely in an initial state, the two urinary tract actuators 1.3 are in a clamping state in which they are staggered in a front-and-back manner. When toggled inwards, the two handle actuators 1.1 move in a relative direction. Driven by the handle actuators, the two connecting shafts 1.2a rotate inwards, such that the two urinary tract actuators 1.3 rotate oppositely to release the urinary tract. At this time, the compressible spring 3.1 is stressed to deform, thereby producing a restoring force for closing the urinary tract. Specifically, when a patient needs to urinate, the urinary tract can be opened for urination simply by manually moving the two urinary tract actuators inwards. When urination is over, as the compressible spring has a restoring force for closing the urinary tract, all that is needed is for the patient to release his hands, and then, under the action of such a restoring force, the two urinary tract actuators will return to the stable state in which the urinary tract is occluded.
Embodiment 2
[0087] Illustrated in FIGS. 4-8 is an implantable urination controlling tool, the remaining features of which are the same as those described in Embodiment 1. The first tool handle and the second tool handle are arranged to be mirror-symmetric with respect to each other, and in particular, parts of the handle actuators 1.1 and the connecting shafts 1.2a are symmetric with respect to the central plane. The handle actuators 1.1 are arc-shaped structures extending towards lateral sides, terminal ends of which are bent inwards. The included angle between the plane formed by two handle actuators 1.1 and the plane formed by two connecting shafts 1.2a is an obtuse angle of 110 degrees. The handle actuators 1.1 may be toggled inwards to make the connecting shafts 1.2a rotate inwards. The connecting shafts 1.2a of the two tool handles 1 are parallelly sleeved in communication holes 2.1 within the fixing block 2. The urinary tract actuators 1.3 of the tool handles 1 are arc-shaped structures bent towards opposite lateral sides. The two urinary tract actuators 1.3 are arranged in a front-and-back crossed manner, terminal ends of which are bent inwards for clamping. However, the urinary tract actuator of the first tool handle is positioned in front of the urinary tract actuator of the second tool handle. Outer sides of the middle segments of the connecting shafts 1.2a of the two tool handles are spring contact surfaces 1.2.1. Grooves 2.2 are disposed in upper portions of the communication holes 2.1 on two sides of the fixing block 2, and the spring contact surfaces 1.2.1 on the middle segments of the connecting shafts 1.2a can be seen through the grooves 2.2. The middle portion of the fixing block 2 is provided on an upper surface thereof with a mounting hole 2.3. The tool handle rotation angle limiting mechanisms 3 are compressible springs 3.1. The compressible springs 3.1 are arched, two ends of which abut the spring contact surfaces 1.2.1. The compressible springs 3.1 are provided in the middle portions thereof with a pin member 3.1.1 for fixedly connecting with the mounting hole 2.3. The compressible springs 3.1 are used for limiting ranges of positive and negative included angles corresponding to the opening and closing actions that can be achieved by the two tool handles 1 when rotating. In other words, when the tool handles 1 rotate, the springs can only be stabilized in the state in which the urinary tract actuators squeeze to block the urinary tract, while other states all are process states, namely, non-stable states. When the compressible springs 3.1 are in a preset pressure state, namely in an initial state, the two urinary tract actuators 1.3 are in a clamping state in which they are staggered in a front-and-back manner. When toggled outwards, the two handle actuators 1.1 move in opposite directions. Driven by the handle actuators, the two connecting shafts 1.2a rotate in opposite directions, such that the two urinary tract actuators 1.3 rotate in opposite directions to release the urinary tract. At this time, the compressible spring 3.1 is stressed to deform, thereby producing a restoring force for closing the urinary tract. Specifically, when a patient needs to urinate, the urinary tract can be opened for urination simply by manually moving the two urinary tract actuators outwards. When urination is over, as the compressible spring has a restoring force for closing the urinary tract, all that is needed is for the patient to release his hands, and then, under the action of such a restoring force, the two urinary tract actuators will return to the stable state in which the urinary tract is occluded. This arrangement serves as a supplementary solution. It may be pinched inwards to function as opening control for the urinary tract, just as the solution described in Embodiment 1; in addition, it may also be manually moved outwards to function as the opening control, just as the solution described in Embodiment 2.
Embodiment 3
[0088] Illustrated in FIGS. 9-11 is an implantable urination controlling tool, the remaining features of which are the same as those described in Embodiment 2. The first tool handle and the second tool handle are arranged to be mirror-symmetric with respect to each other, and in particular, parts of the handle actuators 1.1 and the connecting shafts 1.2a are symmetric with respect to the central axis. The handle actuators 1.1 are arc-shaped structures extending towards lateral sides, terminal ends of which are bent inwards. The included angle between the plane formed by two handle actuators 1.1 and the plane formed by two connecting shafts 1.2a is an obtuse angle of 120 degrees. The handle actuators 1.1 may be toggled inwards to make the connecting shafts 1.2a rotate inwards. The connecting shafts 1.2a of the two tool handles 1 are parallelly sleeved in communication holes 2.1 within the fixing block 2. The urinary tract actuators 1.3 of the tool handles 1 are also arc-shaped structures bent towards opposite lateral sides, terminal ends of which are bent inwards for clamping. However, the urinary tract actuator of the first tool handle is positioned in front of the urinary tract actuator of the second tool handle. The middle segments of the connecting shafts 1.2a of the two tool handles are each provided with a connecting segment 1.2.2 shaped like a Chinese character Ji. The connecting segment 1.2.2 protrudes outwards, the upper surface of which is a spring contact surface 1.2.1. Grooves 2.2 are disposed in upper portions and lateral sides of the communication holes 2.1 on two sides of the fixing block 2, and the connecting segments 1.2.2 extend outwards from the grooves 2.2. The upper portion in the middle of the fixing block 2 is provided with a mounting hole 2.3. The tool handle rotation angle limiting mechanisms 3 are compressible springs 3.1. The compressible springs 3.1 are plate-shaped, two ends of which abut the spring contact surfaces. The compressible springs 3.1 are provided in the middle portions thereof with a pin member 3.1.1 for fixedly connecting with the mounting hole 2.3. The compressible spring 3.1 are used for limiting ranges of positive and negative included angles corresponding to the opening and closing actions that can be achieved by the two tool handles 1 when rotating. In other words, when the tool handles 1 rotate, the spring can only be stabilized in the state in which the urinary tract actuators squeeze to block the urinary tract, while other states all are process states, namely, non-stable states. When the compressible spring 3.1 is in a preset pressure state, namely in an initial state, the two urinary tract actuators 1.3 are in a clamping state in which they are staggered in a front-and-back manner. When toggled inwards, the two handle actuators 1.1 move in a relative direction. Driven by the handle actuators, the two connecting shafts 1.2a rotate inwards, such that the two urinary tract actuators 1.3 rotate oppositely to release the urinary tract. At this time, the compressible spring 3.1 is stressed to deform, thereby producing a restoring force for closing the urinary tract. Specifically, when a patient needs to urinate, the urinary tract can be opened for urination simply by manually moving the two urinary tract actuators inwards. When urination is over, as the compressible spring has a restoring force for closing the urinary tract, all that is needed is for the patient to release his hands, and then, under the action of such a restoring force, the two urinary tract actuators will return to the stable state in which the urinary tract is occluded.
Embodiment 4
[0089] Illustrated in FIGS. 12-16 is an implantable urination controlling tool. The tool handles 1 are each composed of a handle actuator 1.1, a connecting shaft 1.2a and a urinary tract actuator 1.3. The handle actuator 1.1 extends from an end of the connecting shaft 1.2a in an upward bending manner, and the urinary tract actuator 1.3 extends from the other end of the connecting shaft in a downward bending manner. The first tool handle and the second tool handle are arranged to be mirror-symmetric with respect to each other, and in particular, parts of the handle actuators 1.1 and the connecting shafts 1.2a are symmetric with respect to the central axis. The included angle between the plane formed by two handle actuators 1.1 and the plane formed by two connecting shafts 1.2a is a right angle of 90 degrees. The handle actuators 1.1 may be toggled inwards to make the connecting shafts 1.2a rotate inwards. The handle actuators 1.1 may be toggled inwards to make the connecting shafts 1.2a rotate inwards The connecting shafts 1.2a of the two tool handles 1 are parallelly sleeved in communication holes 2.1 within a fixing block 2. The urinary tract actuators 1.3 of the tool handles 1 are also arc-shaped structures bent towards opposite lateral sides, terminal ends of which are bent inwards for clamping. However, the urinary tract actuator of the first tool handle is positioned in front of the urinary tract actuator of the second tool handle. The urinary tract actuators 1.3 are used for squeezing the urinary tract, and the urinary tract actuators on the two tool handles are arranged in a front-and-back crossed manner along the direction of the urinary tract, i.e. that the urinary tract is clamped between two urinary tract actuators. Moreover, the two urinary tract actuators do not clamp at the same point on the urinary tract; rather, they are always in a state in which they are staggered in a front-and-back manner. It may also be considered that the connecting shafts 1.2a of the two tool handles are different in length, thereby ensuring that the two urinary tract actuators 1.3 do not clamp at the same point on the urinary tract when the handle actuators 1.1 are mounted in the same plane. The tool handle rotation angle limiting mechanisms 3 are permanent magnet assemblies, which each comprise a fixing block permanent magnet 3.2 and a tool handle permanent magnet 3.3. The tool handle rotation angle limiting mechanisms 3 each composed of the tool handle permanent magnet 3.3 and the fixing block permanent magnet 3.2 is used for limiting the range of positive and negative included angles corresponding to the opening and closing actions that can be achieved by the two tool handles when rotating. In other words, when the tool handles 1 rotate, the mechanism can only be stabilized in the state in which the urinary tract actuators squeeze to block the urinary tract and the state in which the urinary tract actuators release to open the urinary tract, while other states all are temporary. During this process, a stable state can be reached only when the tool handle permanent magnet 3.3 and the fixing block permanent magnet 3.2 fully abut together. The fixing block permanent magnet 3.2 is disposed on an end of the fixing block 2, and its S pole and N pole are disposed above and below the fixing block 2, respectively. Moreover, the tool handle permanent magnet 3.3 is disposed on the connecting shaft 1.2a corresponding to the end of the fixing block 2. The tool handle permanent magnet on the connecting shaft 1.2a is oppositely arranged, i.e. that the N pole is disposed above, while the S pole is disposed below. The connecting shafts 1.2a of the two tool handles 1 are each provided with the tool handle permanent magnet 3.3, and the three permanent magnets may attract one another directly. The permanent magnet attraction above serves as a closing stable state, while the permanent magnet attraction below serves as an opening stable state. The handle actuators may be toggled to make the urinary tract actuators rotate outwards to open the urinary tract. When urination is over, the handle actuators may then be toggled inwards to make the urinary tract actuators rotate inwards to close the urinary tract.
Embodiment 5
[0090] Illustrated in FIGS. 17 and 18 is an implantable urination controlling tool, which is composed of two tool handles 1, a pin shaft 2.5 and a torsion spring 3.4. The tool handles 1 each comprise a handle actuator 1.1, a connecting strip 1.2b and a urinary tract actuator 1.3. The handle actuator 1.1 is an arc-shaped structure, an end of which is connected to the middle portion of the connecting strip 1.2b, and the other end is bent inwards. Two handle actuators 1.1 are arranged to be mirror-symmetric with respect to each other, and the plane formed by them is perpendicular to the connecting strip 1.2b. The urinary tract actuator 1.3 is an arc-shaped structure having a distal end bent inwards. One of the tool handles 1 is provided with two urinary tract actuators 1.3, which are arranged at two ends of the connecting strip 1.2b corresponding to the handle actuator 1.1. The other tool handle 1 is provided with one urinary tract actuator 1.3, which is arranged in the middle of the connecting strip 1.2b corresponding to the handle actuator 1.1. The inwards-bent structures of the urinary tract actuators 1.3 all are arranged inwards in a face-to-face manner for clamping the urinary tract. Moreover, the urinary tract actuator 1.3 on one side is positioned between two urinary tract actuators 1.3 on the other side, and the three are arranged in a staggered manner to clamp the urinary tract. The two connecting strips 1.2b are provided respectively with a pin shaft mounting lug 1.21b. The pin shaft mounting lugs 1.21b are provided with mounting holes 1.211b having an identical diameter, and the pin shaft 2.5 rotationally connects the two connecting strips 1.2b through the mounting holes 1.211b. When the relative rotation of the two tool handles 1 reaches a set angle, spacing protrusions 3.5 arranged on one connecting strip 1.2b will come into contact with spacing protrusions 3.5 arranged on the opposite connecting strip 1.2b so as to prevent the two tool handles 1 from continuing to rotate, thereby reaching the purpose of spacing. The torsion spring 3.4 is arranged on the pin shaft 2.5. One of its leads is placed on the connecting strip 1.2b on one side, and the other one of its leads is placed on the connecting strip 1.2b on the other side. The action force of the torsion spring 3.4 maintains the two tool handles 1 in a stable state in which the urinary tract is occluded, namely a state in which the urinary tract actuators 1.3 approach one another to clamp the urinary tract. When urination is required, an external force may be applied to make the handle actuators 1.1 approach each other in an inward direction. At this time, the torsion spring 3.4 is compressed, and the urinary tract actuators 1.3 move away from one another, thereby releasing the urinary tract and rendering it in a urination state.
[0091] The preferred embodiments of this invention-creation have been described above in detail, but this invention-creation is not limited to the described embodiments. Without departing from the spirit of this invention-creation, those skilled in the art may make various equivalent modifications or substitutions that are covered by the scope defined in the claims of the present application.
