[0029] This embodiment discloses a medical device, including a cystoscope and other cooperating instruments, such as a resectoscope, a display connector, etc. The cystoscope is installed with a positioning sensor through a sensor connecting piece. The structure of the sensor connecting piece will be described in detail below.

[0030] Please refer to Figure 1 , Figure 2 andFigure 3 The sensor connecting piece includes a first half shell 100 and a second half shell 200. The first half shell 100 has a first half cavity. A first profiling notch 101 is provided at the first end of the first half cavity, a second profiling notch 102 is provided at the second end of the first half cavity, and a third profiling notch 103 is provided between the first end and the second end of the first half shell 100. A sensor fixing part 110 is provided on the outer wall of the first half shell 100. The second half shell 200 is detachably connected to the first half shell 100. The second half shell 200 has a second half cavity. The second half cavity is adapted to the first half cavity and forms a cavity. The second half shell 200 is further provided with a fourth profiling notch 201, a fifth profiling notch 202 and a sixth profiling notch 203. The fourth profiling notch 201 is adapted to the first profiling notch 101 and forms a first through hole 210. The fifth profiling notch 202 is adapted to the second profiling notch 102 and forms a second through hole 220. The sixth profiling notch 203 is adapted to the third profiling notch 103 and forms a third through hole 230. The first through hole 210, the second through hole 220 and the third through hole 230 are all communicated with the cavity.

[0031] Wherein, a water inlet is provided between the first end and the second end of the cystoscope 10. The shapes of the first half cavity and the second half cavity are both adapted to the connecting part 120 of the cystoscope 10 respectively. When the cystoscope 10 is buckled and connected in the cavity, the first half shell 100 and the second half shell 200 can closely fit the cystoscope 10. The first through hole 210 and the second through hole 220 can respectively avoid the first end and the second end of the cystoscope 10, so as to buckle the first half shell 100 and the second half shell 200 on the outer wall of the cystoscope 10. The third through hole 230 is located between the first through hole 210 and the second through hole 220 and is adapted to the water inlet of the cystoscope 10. The third through hole 230 can limit and fix the first half shell 100 and the second half shell 200 on the basis of the first through hole 210 and the second through hole 220, avoiding the relative movement or rotation of the first half shell 100 and the second half shell 200 relative to the cystoscope 10, so that the positioning sensor 20 installed on the sensor fixing part 110 can be reliably connected to the cystoscope 10.

[0032] In this way, the first half shell 100 and the second half shell 200 achieve three-point positioning through the first through hole 210, the second through hole 220 and the third through hole 230, and the positioning sensor 20 can be reliably connected to the cystoscope 10. The first through hole 210, the second through hole 220 and the third through hole 230 are all formed by profiling notches, which can strengthen the connection tightness between the first half shell 100, the second half shell 200 and the cystoscope 10, thereby improving the connection reliability between the positioning sensor 20 and the cystoscope 10.

[0033] In some application examples (this example is not shown in the figure), the sensor fixing portion 110 is an elastic claw with an opening, for example, the elastic claw has a first half claw and a second half claw, the first half claw and the second half claw are arranged in mirror symmetry, the first half claw and the second half claw both have an arc-shaped elastic structure, and a gap is provided between the first half claw and the second half claw to facilitate the positioning sensor 20 to be clamped between the first half claw and the second half claw, thereby clamping and fixing the positioning sensor 20 by the first half claw and the second half claw.

[0034] For other application examples, see Figure 1 , Figure 2 and Figure 3 The sensor fixing part 110 is a columnar structure, and a sensor accommodating cavity 111 is provided in the sensor fixing part 110. The positioning sensor 20 can be inserted into the sensor accommodating cavity 111, so as to be circumferentially wrapped by the sensor fixing part 110, which is beneficial to improve the connection reliability of the positioning sensor 20 and reduce the possibility of accidental detachment.

[0035] An elastic arm 112 is provided on the sensor fixing portion 110 and on the side wall of the sensor accommodating cavity 111. When the positioning sensor 20 is inserted into the sensor accommodating cavity 111, the positioning sensor 20 can squeeze the elastic arm 112, so that the elastic arm 112 opens. When the positioning sensor 20 is installed in place, the elastic arm 112 continues to apply pressure to the positioning sensor 20 under the action of its own elastic force, thereby fixing the positioning sensor 20, which is conducive to improving the convenience of installation and removal of the positioning sensor 20. Among them, the elastic arm 112 can be an elastic structure extending from the side wall of the sensor fixing portion 110, or it can be an elastic structure located on the side wall of the sensor fixing portion 110.

[0036] For the elastic arm 112 located on the side wall of the sensor fixing part 110, a hollow groove 113 is provided between the elastic arm 112 and the side wall of the sensor fixing part 110. The hollow groove 113 can provide a certain elastic activity space between the elastic arm 112 and the side wall of the sensor fixing part 110, and the elastic arm 112 can be directly processed on the side wall of the sensor fixing part 110 without occupying additional space, which is conducive to simplifying the structure, processing technology and reducing processing costs. It should be noted that the hollow groove 113 can be U-shaped, T-shaped or special-shaped, and the shape of the elastic arm 112 is adapted to the hollow groove 113.

[0037] The sensor fixing part 110 is a cylindrical structure, a prismatic structure or a rectangular parallelepiped structure. It is worth mentioning that the shape of the sensor fixing part 110 can be designed according to the needs of the actual application, and the shape of the sensor accommodating cavity 111 is adapted to the positioning sensor 20. For example, for a cylindrical positioning sensor 20, the sensor accommodating cavity 111 is usually set to a cylindrical shape, and the shape of the sensor fixing part 110 can be set to a cylindrical, prismatic or rectangular parallelepiped structure. For the sensor fixing part 110 with a rectangular parallelepiped structure, the elastic arm 112 can be set on multiple side walls of the sensor fixing part 110, so as to fix the positioning sensor 20 at multiple angles.

[0038] When in use, the positioning sensor 20 needs to be connected to an external device via a cable. In order to avoid interference between the cable of the positioning sensor 20 and, for example, the cystoscope 10 or a supporting structure of the cystoscope 10, and to avoid interference to the operator by the cable of the positioning sensor 20, such as blocking the field of vision, please refer to Figure 3 A connecting portion 120 is provided between the sensor fixing portion 110 and the outer wall of the first half shell 100 so that a non-zero inclination angle is formed between the sensor fixing portion 110 and the first half shell 100. In this way, the cable direction of the positioning sensor 20 can be as consistent as possible with the cable direction of the overall surgical instrument, which is conducive to improving the convenience of use.

[0039] For some application examples, see Figure 1 , Figure 2 and Figure 3 , the first side of the first half shell 100 is hingedly connected to the second half shell 200, and the second side of the first half shell 100 is snap-fittedly connected to the second half shell 200. For example, the first side of the first half shell 100 is connected to the first side of the second half shell 200 via a hinge shaft 130, such as Figure 3 The hinge shaft 130 shown in the figure, and the second side of the first half shell 100 is connected to the second side of the second half shell 200 by a buckle or a screw buckle or other buckle structure, such as Figure 3 The first buckle portion 141 and the second buckle portion 142 are shown. For another example, the first half shell 100 and the second half shell 200 are integrally formed by injection molding, the first side of the first half shell 100 and the first side of the second half shell 200 are plastically connected and can rotate around the connection, and the second side of the first half shell 100 and the second side of the second half shell 200 are connected by a buckle or a screw buckle or other buckle structure.

[0040] In some other application examples (not illustrated in this example), both opposite sides of the first half shell 100 are snap-connected to the second half shell 200. Among them, the snap connection can be through a snap structure or a twist-lock structure. The snap connection can adopt wedge-shaped snap, or it can also adopt female snap through-hole rabbet protrusion snap, rabbet through-hole female snap rib protrusion snap, elastic snap, movable push-open snap, toggle spring snap, etc.

[0041] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art, various changes can be made without departing from the gist of the present invention.
