DESCRIPTION OF EMBODIMENTS

Embodiment 1: Direct-Vision Abortion Uterine Curettage Device of the Present Application with Curette Spoon

[0082] Referring to FIG. 1 to FIG. 1-4, the direct-vision abortion uterine curettage device of this embodiment includes a uterine curettage mechanism 1, an observation mechanism 2, a circuit 3, a negative pressure suction mechanism 4 and an operating rod 5.

[0083] The uterine curettage mechanism 1 includes at least one diagnostic curette 11, and the diagnostic curette 11 is arranged at a front end of the operating rod 5 and is in a visual field of the observation mechanism 2.

[0084] The observation mechanism 2 includes an illumination module 21, a lens module 22 and a signal processing module 23. Images and videos observed by the lens module 22 in a light field of the illumination module 21 are processed by the signal processing module 23, and then output by the circuit 3.

[0085] The negative pressure suction mechanism 4 includes a suction inlet 41, a suction outlet 42 and a suction channel 43. The suction inlet 41 is arranged at the front end of the operating rod 5; the suction outlet 42 of the negative pressure suction mechanism 4 is arranged at a rear end of the operating rod 5; and the suction channel 43 is arranged in the operating rod 5.

[0086] The rear end 5-2 of the operating rod 5 is provided with a handle 52, and the front end 5-1 of the operating rod 5 is provided with the uterine curettage mechanism 1 and the observation mechanism 2. The circuit 3 and the negative pressure suction mechanism 4 are located in a pipe body 5-3 of the operating rod 5.

[0087] Referring to FIG. 1, in this embodiment, the diagnostic curette 11 is a curette spoon 11-1. A front end of the curette spoon 11-1 is a blunt end, and a curette hook 11-11 of the curette spoon 11-1 is bent inward. The design of the blunt end may prevent the curette spoon 11-1 from accidentally puncturing the tissue at the front end of the curette spoon 11-1 during the forward moving process, and the clinical use process is safer. The inward bent curette hook 11-11 may conveniently remove the implanted embryo tissue.

[0088] In this embodiment, the curette spoon 11-1 is made of a transparent medical material. The transparent material may guarantee that the curette spoon 11-1 may not block an observation path of the camera 22-1, thereby guaranteeing that the tissue at the front end of the curette spoon 11-1 may also be observed by the observation mechanism 2, and guaranteeing the whole-process and overall-area observation of the operation procedure.

[0089] Referring to FIG. 1-2 and FIG. 1-3, in this embodiment, the lens module 22 includes a camera 22-1, and the camera 22-1 is arranged at the rear end of the diagnostic curette 11. The illumination system 21 is a light-emitting diode (LED) lamp arranged around the camera 22-1. The diagnostic curette 11 is in the visual field of the camera 22-1.

[0090] The observation mechanism 2 further includes a protective cover 20, and the protective cover 20 may prevent accidents such as short circuit of the observation mechanism 2 caused by fluids. The protective cover 20 of the observation mechanism 2 is provided with a coating. A hydrophobic coating may be selected, so that fluids such as watery blood may quickly condense into water droplets on the protective cover 20 and then slide off. A hydrophilic coating may also be selected, so that fluids such as watery blood may quickly form a transparent water film on a surface of the protective cover 20 without blocking the camera.

[0091] Referring to FIG. 1-2, in this embodiment, the direct-vision abortion uterine curettage device 100 further includes a flushing mechanism 6. A water outlet 61 of the flushing mechanism 6 is located at the front end of the operating rod 5; a water inlet 62 of the flushing mechanism 6 is located at the rear end of the operating rod 5; and a water inlet pipeline 63 of the flushing mechanism 6 is located in the pipe body 5-3 of the operating rod 5. The flushing mechanism 6 may flush the inside of the uterus during the operation procedure, and may flush the watery blood at the front end of the camera 22-1 in time to guarantee that the visual field of observation is kept clean. At the same time, the flushing mechanism 6 may also flush the diagnostic curette 11 and the uterus wall in time, especially may flush a surgical site in time, so as to observe whether the embryo tissue has been completely removed from the implantation position in time to guarantee the completeness of the embryo tissue during the abortion operation procedure and effectively avoid the condition of incomplete abortion, and the clinical operation procedure is safer.

[0092] In this embodiment, the direct-vision abortion uterine curettage device 100 further includes the flushing mechanism 6. Therefore, in this embodiment, the pipe body 5-3 of the operating rod 5 is a three-cavity pipe. The circuit 3 is arranged in the first cavity pipe, the second cavity pipe constitutes or is provided with the suction channel 43 of the negative pressure suction mechanism 4, and the third cavity pipe constitutes or is provided with the water inlet pipeline 63 of the flushing mechanism 6. The design of the three-cavity channel may separate a flushing channel from the suction channel while guaranteeing that the circuit 3 is isolated and protected, so as to better guarantee that no sucked tissue or fluid will return to the uterus during the flushing process, and the use process is more efficient and safer.

[0093] In practical applications, when the direct-vision abortion uterine curettage device 100 does not include the flushing mechanism 6, the pipe body 5-3 of the operating rod 5 may be designed into a double-cavity pipe. The circuit 3 is arranged in one cavity pipe, and the other cavity pipe constitutes or is provided with the suction channel 43 of the negative pressure suction mechanism 4. The design of the double-cavity channel avoids accidents such as short circuit and electric leakage, and at the same time, the structure is simpler.

[0094] Water sprayed from at least one water outlet 61 of the water outlets 61 of the flushing mechanism 6 of the direct-vision abortion uterine curettage device 100 may flush and clean the protective cover 20 of the observation mechanism 2, thereby guaranteeing the observation effect of the observation mechanism 2. Referring to FIG. 1-3, in this embodiment, the flushing mechanism 6 includes three water outlets 61. The first water outlet 61 is arranged close to the protective cover 20 and may flush the protective cover 20, thereby guaranteeing the observation effect of the observation mechanism 2. The second water outlet 61 is arranged close to the bottom of the curette hook 11-11 of the curette spoon 11-1 and may flush a curette surface of the curette hook 11-11, thereby guaranteeing the cleanliness of an inner surface of the curette hook 11-11. The third water outlet 61 is arranged at the front end of the curette spoon 11-1 and may flush an outer surface of the curette spoon 11-1 and surrounding operation areas, thereby observing whether the embryo tissue has been completely removed from the implantation position in time to guarantee the completeness of the embryo tissue during the abortion operation procedure and effectively avoid the condition of incomplete abortion.

[0095] In this embodiment, the flushing mechanism 6 is provided with a flushing switch 64 for controlling flushing water. The flushing switch 64 may start and stop the flushing mechanism 6, and may control the water volume and flushing pressure of the flushing water. During the clinical use process, clinicians may start or stop the flushing mechanism 6 according to actual needs of the operation procedure, and select the appropriate volume and pressure of the flushing water according to needs, and the clinical use process is more convenient.

[0096] The flushing switch 64 is arranged on the handle 52 of the operating rod 5. By arranging the flushing switch 64 on the handle 52, the medical staff may realize one-handed operation during clinical use, and the use process is more convenient.

[0097] The negative pressure suction mechanism 4 is provided with a negative pressure control switch 44 capable of controlling a negative pressure state. The negative pressure control switch 44 may start or stop the negative pressure suction mechanism 4, and may adjust the negative pressure suction force of the negative pressure suction mechanism 4 according to the volume of the peeled tissue, watery blood and tissue fluids in the uterus during the operation procedure. During clinical use, doctors may conveniently adjust the needed negative pressure suction force, so as to avoid that the peeled tissue may not be sucked out in time due to a too small negative pressure suction force, and avoid accidental injuries to the endometrium and other tissues due to a too large negative pressure suction force.

[0098] The negative pressure control switch 44 is arranged on the handle 52 of the operating rod 5. By arranging the negative pressure control switch on the handle 52, the medical staff may realize one-handed operation during clinical use, and the use process is more convenient.

[0099] Referring to FIG. 1-4, the circuit 3 is provided with an electrical interface 31 connected with a host.

[0100] The direct-vision abortion uterine curettage device 100 further includes an identification system 8. The identification system 8 may prompt the depth of the operating rod 5 into the human body. In this embodiment, the identification system 8 is a graduated scale 81 arranged outside the operating rod 5. Of course, in practical applications, those skilled in the art may also design the identification system 8 into other identification methods which are not specifically illustrated by the applicant here one by one, but do not depart from the protection scope of the present application.

[0101] During a clinical operation, the handle 52 is held, under the condition of direct vision, the direct-vision abortion uterine curettage device 100 enters the uterus through the cervix along the vagina, the implantation position of the embryo tissue is found through the camera 22-1, and then, the curette hook 11-11 of the curette spoon 11-1 is used to remove the embryo tissue from the uterus wall. The removed embryo tissue is sucked from the suction inlet 41 under the negative pressure suction action of the negative pressure suction mechanism 4, and is discharged out of the body through the suction outlet 42 after passing through the suction channel 43. During the suction process, doctors may adjust the magnitude of the negative pressure suction force through the control switch 44 arranged on the handle 52 according to the size of the removed tissue and the volume of watery blood. During the operation procedure, the flushing mechanism 6 may be used for flushing. On the one hand, the protective cover 20 of the observation mechanism 2 may be flushed in time to keep the real-time observation effect of the observation mechanism 2 good and stable; and on the other hand, the curette spoon 11-1 and the operation area may be flushed, thereby observing whether the embryo tissue has been completely removed from the implantation position in time to guarantee the completeness of the embryo tissue during the abortion operation procedure and effectively avoid the condition of incomplete abortion, and the clinical operation procedure is safer.

[0102] In this embodiment, the technical solution of the camera 22-1 being mounted at the rear may guarantee that the diagnostic curette 11 is completely within a range of the visual field of the camera 22-1, and since an observation angle of the camera 22-1 faces the front of an operation area, there will be no observation blind areas during the observation process. As a result, there will be no accidental injuries to the uterus and uterine appendages caused by the failure to observe clearly in time. At the same time, since the diagnostic curette 11 is located in front of the camera 22-1, there will be no operation blind spots due to the diagnostic curette 11 being blocked by the height of the lens module 22 itself. The embryo tissue implanted at any position of the uterus, especially near the oviduct orifice, may be completely removed, i.e. the diagnostic curette 11 may also easily remove the embryo tissue at the implantation position of the uterine fundus, and the condition of incomplete abortion may be avoided during the operation procedure. Moreover, since the removal is performed under direct vision, an accidental injury to the uterine fundus due to an excessive surgical action may be avoided, the injury to the uterine fundus may be well avoided, and serious medical accidents such as perforation of uterus may be avoided. The clinical operation procedure is very safe and efficient.

Embodiment 2: Direct-Vision Abortion Uterine Curettage Device of the Present Application with Curette Cup

[0103] Referring to FIG. 2 to FIG. 2-3, the difference between this embodiment and Embodiment 1 is that: in this embodiment, the diagnostic curette 11 is a curette cup 11-2.

[0104] A front end of the curette cup 11-2 is a blunt end, and at least one diagnostic curette strip 11-21 is arranged around the blunt end. The design of the blunt end may guarantee that the curette cup 11-2 may not accidentally puncture the tissue at the front end of the curette cup 11-2 during the forward moving process. During clinical use, the diagnostic curette strip 11-21 may conveniently remove the implanted embryo tissue from the uterus.

[0105] Referring to FIG. 2-2 and FIG. 2-3, in this embodiment, a curette table 11-23 provided with a through hole 11-22 is arranged at the front end of the curette cup 11-2. During a clinical operation, especially when the implantation position of the embryo tissue is at the uterine fundus, as long as the curette cup 11-2 is rotated, the curette table 11-23 also rotates, and then, the embryo tissue may be removed from the uterine fundus. During clinical use, the curette cup may adapt to different embryo implantation positions.

[0106] The curette cup 11-2 is made of a transparent medical material. The transparent material may guarantee that the curette cup 11-2 may not block the observation path of the camera 22-1, thereby guaranteeing that the tissue at the front end of the curette cup 11-2 may also be observed by the observation mechanism 2, and guaranteeing the whole-process and overall-area observation of the operation procedure.

[0107] In this embodiment, the diagnostic curette 11 is the curette cup 11-2. The curette table 11-23 may be formed at the bottom of the curette cup 11-2, and the curette table 11-23 is located at the most front end of the direct-vision abortion uterine curettage device 100, so that the curette table 11-23 may be attached to the uterus to remove the embryo tissue, and may also completely remove the embryo tissue even at the implantation position of the uterine fundus conveniently.

Embodiment 3: Direct-Vision Abortion Uterine Curettage Device of the Present Application with Curette Mesh

[0108] Referring to FIG. 3 to FIG. 3-4, the difference between this embodiment and Embodiment 1 is that: in this embodiment, the diagnostic curette 11 is a curette mesh 11-3.

[0109] In this embodiment, the diagnostic curette 11 of the uterine curettage mechanism 1 is a curette mesh 11-3. Through the camera 22-1, the condition behind the curette mesh 11-3 may be directly observed from mesh gaps, and even if the curette mesh 11-3 is not made of a transparent material, the whole-process observation of the operation procedure and the panoramic observation of the operation area may be realized.

[0110] Referring to FIG. 3, in this embodiment, the curette mesh 11-3 of the diagnostic curette 11 of the uterine curettage mechanism 1 may be compressed in a sheath pipe 5-0, and after the constraint of the sheath pipe 5-0 is removed backward, the curette mesh 11-3 may be completely restored or basically restored to a shape before compression.

[0111] Referring to FIG. 3-1, the curette mesh 11-3 includes at least one diagnostic curette wire 11-31. In this embodiment, the curette mesh 11-3 is formed by winding two diagnostic curette wires 11-31 and has a cross shape, and the top end is wound by the diagnostic curette wires 11-31 to form an annular platform.

[0112] In practical applications, the curette mesh 11-3 may be formed by winding one diagnostic curette wire 11-31 or superimposing a plurality of diagnostic curette wires 11-31 after being wound. Moreover, the curette mesh 11-3 may be manufactured in any shapes which are not illustrated by the applicant here one by one, but do not depart from the protection scope of the present application.

[0113] The diagnostic curette 11 of the uterine curettage mechanism 1 may also be a woven mesh made of a wire material. The design of the soft woven mesh makes the force applied during the implanted embryo removing process more gentle and even, so that the injury to the uterus is less.

[0114] The curette mesh 11-3 is made of a medical elastic material. The curette mesh 11-3 may guarantee the removing effect, and at the same time, during the forward moving process, the elastic action of the medical elastic material may play a good buffering effect, so that the curette mesh 11-3 will not cause an accidental injury to the uterus due to an excessively fast moving speed.

[0115] The curette mesh 11-3 is made of medical elastic stainless steel or medical titanium-nickel shape memory alloy. Here, the applicant only lists the above two medical metallic elastic materials. In practical applications, those skilled in the art may also select different medical elastic materials for manufacturing according to needs, and all the medical elastic materials do not depart from the protection scope of the present application.

[0116] The curette mesh 11-3 is made of a medical transparent elastic polymer material. The curette mesh 11-3 may also be made of the medical transparent elastic polymer material, so that the observation path of the camera 22-1 may not be blocked while guaranteeing elastic buffering, and the observation effect is better.

[0117] In order to guarantee the safety in clinical use of the direct-vision abortion uterine curettage device 100, the direct-vision abortion uterine curettage device 100 adopts a disposable design. The disposable use may be realized through a control program design, such as setting a use time, or may be realized through a structural design. Referring to FIG. 3-5, for example, a tearable casing 5-4 may be arranged outside the direct-vision abortion uterine curettage device 100. After the direct-vision abortion uterine curettage device 100 enters the uterus, the casing 5-4 needs to be torn off, and the curette mesh 11-3 is released. After the operation is completed, when the direct-vision abortion uterine curettage device 100 is taken from the body, since the curette mesh 11-3 has been released, the curette mesh 11-3 may not enter the body again for repeated use, so as to realize disposable use of the direct-vision abortion uterine curettage device 100.

[0118] In this embodiment, the curette mesh 11-3 is made of an elastic material, the curette mesh 11-3 may guarantee the removing effect, and at the same time, during the forward moving process, the elastic action of the medical elastic material may play a good buffering effect, so that the curette mesh 11-3 will not cause an accidental injury to the uterus due to an excessively fast moving speed. The use process is safer.
