For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0039] As Figures 1-11 shown, a surgical enucleation and comminution device provided by the present utility model includes a sealing piece 1, an endoscope channel 2, an enucleation channel 3, a first seal 7, and an operating cylinder 14.

[0040] Among them, a partition piece 11 is provided inside the operating cylinder 14 for dividing the central cavity of the operating cylinder 14 into a water inlet channel 4 and a water outlet channel 5. Among them, the partition piece 11 is an arc-shaped structure. Specifically, the longitudinal cross-sectional area of the water inlet channel 4 is smaller than that of the water outlet channel 5. In this way, when the water flows into the patient's body from the water inlet 15 of the water inlet channel 4 and flows out from the water outlet 16 of the water outlet channel 5, it can ensure to the greatest extent that the water outlet channel 5 will not be blocked by the tissues enucleated in the water flow.

[0041] In practical applications, a negative pressure device is connected to the water outlet 16.

[0042] As Figure 2 shown, the endoscope channel 2 is arranged at the center of the water inlet channel 4, and the water inlet 15 is arranged on one side of the endoscope channel 2. In this way, the endoscope channel 2 does not block the water inlet 15, ensuring that the water flows smoothly into the operating cylinder 14.

[0043] The enucleation channel 3 is arranged in the water outlet channel 5, and the end of its channel is hermetically fixed by a third seal 12.

[0044] The sealing piece 1 is arranged at the end of the operating cylinder 14 for sealing the ends of the operating cylinder 14, the endoscope channel 2, and the enucleation channel 3.

[0045] To improve the sealing performance of the endoscope channel 2 and the enucleation channel 3, sealing connectors are provided at the joints of the enucleation channel 3 and the endoscope channel 2 with the sealing piece 1. Specifically, a second seal 10 is provided at the joint of the sealing piece 1 and the endoscope channel 2, and a third seal 12 is provided at the joint of the sealing piece 1 and the enucleation channel 3.

[0046] To facilitate the shredder 19 in shredding the excised tissue, a shredder interface 6 is provided at the horizontal position of the sealing piece 1 and the water outlet channel 5. The shredder interface 6 has a cross-shaped opening. Specifically, the material of the shredder interface 6 is medical silica gel. During use, the front end of the shredder 19 is inserted into the shredder interface 6, and then it is sealed and fixed by a first seal 7 provided above the shredder interface 6.

[0047] The first seal 7, the second seal 10, and the third seal 12 in the embodiments of the present utility model have the same structure, and each includes an annular threaded seal opening, a first seal cap 72, and a second seal cap 73. Among them, Figures 7-10 Taking the first seal 7 as an example for illustration. When not in use, the annular threaded seal opening is connected to the first seal cap 72 to prevent the liquid in the operating cylinder from flowing out. When in use, the annular threaded seal opening is connected to the second seal cap 73 to facilitate the passage of surgical instruments.

[0048] As Figure 7 shown, a plurality of arc-shaped opening pieces are provided at the opening of the annular threaded seal opening 71, and there are gaps between the plurality of arc-shaped opening pieces. Among them, the material of the arc-shaped opening pieces is medical silica gel.

[0049] The second seal cap 73 has a frustum-shaped cavity with a larger upper part and a smaller lower part inside, and the volume of the frustum-shaped cavity is smaller than the cavity formed by the arc-shaped opening pieces. A cylindrical cavity is also provided at the frustum-shaped cavity with the smallest longitudinal area. In this way, when in use, the second seal cap 73 and the annular threaded seal opening are mutually matched by threads. The frustum-shaped cavity of the second seal cap 73 presses the arc-shaped opening pieces inward, so that the arc-shaped opening pieces are tightly pressed between the cylindrical cavity and the shredder 19, thereby realizing the sealing and fixing at the connection between the shredder 19 and the sealing piece 1.

[0050] During the surgical process, when it is necessary to replace the cystoscope with a nephroscope, and when inserting the shredder 19 into the shredder interface 6, in order to prevent water from flowing out of the shredder interface 6 and the second seal 10, further, a telescopic connecting pipe 13 is also provided between the first seal 7 and the sealing piece 1, and between the second seal 10 and the sealing piece 1. In this way, when replacing the endoscope and inserting the shredder 19, the telescopic connecting pipe 13 can be first stretched and bent upward to make the opening of the first seal 7 or the second seal 10 face upward, preventing the water flow in the operating cylinder from flowing out. Then, the endoscope can be inserted into the telescopic connecting pipe 13, and then the second seal cap 73 is connected to the annular threaded seal opening to complete the replacement of the endoscope; or, the shredder 19 is inserted into the shredder interface 6, and then the second seal cap 73 is connected to the annular threaded seal opening to complete the insertion and fixing operation of the shredder 19.

[0051] Among them, the telescopic connecting pipe 13 is made of medical PVC material. Specifically, the telescopic connecting pipe 13 is integrally connected to the sealing piece 1 and the first seal 72 respectively. Among them, the telescopic connecting pipe 13 is a deformable structure. Further, the telescopic connecting pipe 13 is a bellows that can be bent upward and is similar to a straw.
