Problems solved by technology

[0003] When laparoscopy is used for cervical cancer surgery, due to the flow of carbon dioxide gas flow forming pneumoperitoneum pressure, if cervical cancer tissue or cancer cells leak, it is easy to cause cancer cells to be seeded in the abdominal cavity. The prior art has no solution to this problem. Effective solution, so laparotomy is clinically recommended to avoid the seeding of cancer cells in the abdominal cavity with the flow of carbon dioxide gas flow

Embodiment 1

[0092] Embodiment 1: Endoscopic cervix banding system of the present invention

[0093] refer to Figure 1 to Figure 1-6, the endoscopic cervix banding system in this embodiment includes a banding device 100 and a delivery device 200.

[0094] refer to Figure 1-4 and Figure 1-5 , the strapping device 100 includes a strapping mechanism 11 , a fixing mechanism 12 and a strapping hole 13 .

[0095] The binding mechanism 11 is provided with at least one positioning groove 11-1, and the fixing mechanism 12 includes a through hole 12-1 and at least one positioning convex step 12-2; the proximal end 101 of the binding mechanism 11 is connected to On the fixing mechanism 12, the distal end 102 of the binding mechanism 11 can pass through the through hole 12-1; when the positioning convex step 12-2 is embedded in the positioning groove 11, it can prevent the The distal end 102 of the binding mechanism 11 is loose or slipped from the fixing mechanism 12 .

[0096] In this embodim...

Embodiment 2

[0115] Embodiment 2: The endoscopic cervix banding system of the present invention containing a push mechanism

[0116] Refer to Fig. 2 to Figure 3-1 3. The difference between this embodiment and Embodiment 1 is that in this embodiment, the delivery device 200 further includes a pushing mechanism 22 .

[0117] The pushing mechanism 22 can push and release the binding device 100 from the delivery sheath 21 .

[0118] , the pushing mechanism 22 may be a linked pushing mechanism 201 connected to the fixing mechanism 12, or may be an independent pushing mechanism 202 capable of pushing the strapping device 100 out through the delivery sheath 21.

[0119] refer to Figure 2 to Figure 2-4 , the proximal end of the independent push mechanism 202 can be provided with a push-pull handle 22-3, push the push-pull handle 22-3, the push rod 22-4 of the independent push mechanism 202 can move in the delivery sheath 21 , push out and release the strapping device 100 folded in the deliver...

Embodiment 3

[0126] Embodiment 3: The endoscopic cervix banding system of the present invention containing an expansion device

[0127] refer to Figure 4 and Pic 4-1 Compared with Embodiment 2 in this embodiment, in this embodiment, the binding mechanism 11 also includes an expansion device 11-4.

[0128] refer to Figure 4-2 , in this embodiment, the opening device 11 - 4 is arranged outside the binding mechanism 11 .

[0129] In practical applications, the binding mechanism 11 may also be a composite structure, for example, composed of a soft elastic coating and an expansion device 11-4 embedded therein. Those skilled in the art can also design other structures of various expansion devices, and the applicant does not give examples here one by one, but they all do not depart from the protection scope of the present application.

[0130] The expansion device 11-4 is an elastic expansion device 11-41. The elastic expansion device 11-41 includes an elastic piece 11-41-1. The elastic ...

Abstract

The invention relates to an endoscopic cervical orifice bundling system. The endoscopic cervical orifice bundling system comprises a bundling device and a delivery device. The bundling device comprises a bundling mechanism, a fixing mechanism and a bundling hole. Due to a one-way moving design, the bundling mechanism can only move towards one direction during clinical use and cannot move reverselyto cause accidental loosing during tissue bundling. The delivery device comprises a delivery sheath, and the bundling device can be retracted in the delivery sheath; and after the endoscopic cervicalorifice bundling system reaches a surgical region through surgical operation channels such as a puncture outfit sheath, the bundling device can be released from the delivery sheath through a pushingmechanism, tissues required to be bundled are placed in the bundling hole, the bundling mechanism is drawn continuously towards a distal end, the bundling hole will be continuously retracted, and finally, the tissues are tightened and closed, so that overflowing of tissue fluid during tissue withdrawing can be effectively prevented, seeding of tumor cells is avoided, and a surgical operation process can be safer. Due to the design of the delivery sheath, the endoscopic cervical orifice bundling system is particularly applicable to endoscopic surgical operations.

Description

technical field [0001] The invention relates to an endoscopic surgical instrument, in particular to an endoscopic cervix banding system used in the endoscopic operation. Background technique [0002] With the development of laparoscopic technology, more and more operations are completed under laparoscopy, including a lot of malignant tumor operations, including hysterectomy for cervical cancer. [0003] When laparoscopy is used for cervical cancer surgery, due to the flow of carbon dioxide gas flow forming pneumoperitoneum pressure, if cervical cancer tissue or cancer cells leak, it is easy to cause cancer cells to be seeded in the abdominal cavity. The prior art has no solution to this problem. Therefore, laparotomy is clinically recommended to avoid the seeding of cancer cells in the abdominal cavity with the flow of carbon dioxide gas flow. [0004] Therefore, it is necessary to develop a strapping device that can be easily delivered into the body during laparoscopic sur...
