Medical Apparatus System

A medical apparatus system (1000) is provided, including a medical apparatus (100) and a fixing plate (900) for fixing the medical apparatus (100). A fixing member (901, 902, 903, 1003, 1004) is formed by cutting along a trajectory (904) on the fixing plate (900); the fixing member (901, 902, 903, 1003, 1004) includes a free end (908, 9031, 10032, 10042) and a connection end (907, 9035, 10031, 10041); the connection end (907, 9035, 10031, 10041) is connected to a fixing plate body (990); the free end (908, 9031, 10032, 10042) can protrude from a plane at which the fixing plate body (990) is located. The fixing member (901, 902, 903, 1003, 1004) can surround an outer surface of the medical apparatus (100) to fix the medical apparatus (100); or the medical apparatus (100) can pass through the fixing member (901, 902, 903, 1003, 1004) and be fixed. The trajectory (904) includes a starting end (905, 1007) and a terminating end (906, 1008). When an outer contour of the fixing member (901, 902, 903, 1001, 1002, 1005, 1006) overlaps the trajectory of the fixing member on the fixing plate, the starting end (905, 1007) rotates outwardly or inwardly with respect to the fixing member (901, 902, 903, 1001, 1002, 1005, 1006) to form a first arc; and the terminating end (906, 1008) rotates outwardly or inwardly with respect to the fixing member (901, 902, 903, 1001, 1002, 1005, 1006) to form a second, arc. The stability of the medical apparatus system (1000) can be ensured under the action of an external force to the medical apparatus system (1000) during transportation.

Active drives for robotic catheter manipulators

An instrument driver comprises opposing rotatable gripping pads. Each of the gripping pads includes an outer circular rim and a center hub. The pads are configured for applying a gripping force to an elongated member. The instrument driver further comprises shafts affixed to the center hubs, and a driver assembly configured for rotating at least one of the shafts, thereby causing the pads to rotate in opposite directions to linearly translate the gripped member. Each of the pads further includes a framework for partially collapsing in response to the gripping force, such that portions of the rims flatten to contact each other. Each rim has a concave gripping surface in order to facilitate vertical centering of the member between the pads. Each of the pads further includes a pair of upper and lower sprockets for interlacing with each other to prevent the elongated member from slipping out between the pads.

Endotracheal intubation devices
11517186 · 2022-12-06 ·

The endoscope herein described has a unique steering capability allowing the highly flexible distal end of the shaft of the device to be moved to a full range angular positions without rotating the device on its long axis, thus enabling the device to be steered within the cavity of interest. The relative lengths of the control cables used to move the distal end of the bendable shaft can be changed whenever the flexible or malleable shaft is to be re-shaped to a new configuration thus preventing the distal end or the steering mechanism from assuming an undesired angular position. When used as an endotracheal device, a novel tongue retractor is described which forms an internal conduit, allowing passage of the bendable shaft of the endotracheal intubation device and an endotracheal tube therethrough. Methods for performing a tracheal intubation and changing the relative lengths of the cables are disclosed.

Circular catheter with non-circular shaping wire

A catheter has a body including a proximal region, a neck region, and a distal region. A shaping wire is disposed within the distal region to predispose it into at least a partial loop, which may have a fixed or variable radius of curvature. The shaping wire includes a distal portion having a circular transverse cross-sectional shape and a proximal portion having a non-circular (e.g., rectangular) transverse cross-sectional shape. The proximal portion of the shaping wire can have a width-to-thickness ratio of at least about 4, such as about 4.67. A transition portion can promote a gradual transition from the circular to the non-circular transverse cross-sectional shape, for example by increasing a width of the shaping wire by about 0.001″ and/or by decreasing a thickness of the shaping wire by about 0.001″ for every about 0.004″ in length through the transition portion.

Aspiration Catheter with an Adjustable Tip for the Intracranial Circulation
