Embodiment 1

[0041] See figure 1 , figure 1 It is a schematic diagram of the composition of the single-hole laparoscopic instrument system used in V-NOTES operation of the present invention. The single-hole laparoscopic instrument system for V-NOTES operation includes: an elastic connecting piece 1 , an air bag 2 , several surgical instrument channels 3 and several fixing pieces 4 .

[0042] See figure 2 , figure 2 It is a schematic diagram of the elastic connector structure. The elastic connector 1 includes an elastic connector body 11 and five connecting sleeves 12 . The elastic connector body 11 in the uninflated state is in a wrinkled state, and the elastic connector body 11 in the inflated state is a tubular structure with an open distal end, and five connecting sleeves 12 are connected and communicated in the proximal end section. The proximal end of the connecting sleeve 12 is closed. The elastic connecting piece 1 has a structure in which the distal end is open and the prox...

Embodiment 2

[0055] The single-hole laparoscopic instrument system for V-NOTES operation in this embodiment is the same as the single-hole laparoscopic instrument system for V-NOTES operation described in Example 1, the only difference lies in the structure of the elastic connector.

[0056] See Figure 7 , Figure 7 It is a structural schematic diagram of another elastic connector. The elastic connector 1 includes an elastic connector body 11 and five connecting sleeves 12 . The elastic connector body 11 in the inflated state is a tubular structure, the distal end is open, and the proximal end section is connected and communicated with five connecting sleeves 12 . The proximal end of the connecting sleeve 12 is open. The elastic connecting piece 1 has a structure with open distal and proximal ends as a whole. The elastic connector body 11 and the five connecting sleeves 12 can be integrally formed. The elastic connector 1 is made of medical elastic material, such as soft silicone.

Embodiment 3

[0059] The single-hole laparoscopic instrument system for V-NOTES surgery in this embodiment is the same as the single-hole laparoscopic instrument system for V-NOTES surgery described in Example 1, the only difference lies in the structure of the surgical instrument channel.

[0060] See Figure 8 , Figure 8 It is a schematic diagram of another surgical instrument channel structure. The surgical instrument channel 3 includes a channel body 31 and a handle 32 . The channel body 31 is in the shape of a round tube, and its proximal end is connected with the handle 32 . The handle 32 is a prism with a square cross section, and the side length is longer than the inner diameter of the channel body 31 . The center of the proximal end surface of the handle 32 is provided with a surgical instrument channel entrance 321 , and a smoke exhaust pipe 322 is provided on the side wall, and a valve 323 is provided on the smoke exhaust pipe 322 . The surgical instrument channel 3 can be i...

Abstract

The invention relates to a single-port laparoscopic instrument system for V-NOTES surgery, including an elastic connector, an air bag, a surgical instrument passages, and a fixture. The elastic connector is provided with a tubular elastic connector body, and the proximal end of the elastic connector body is connected with a connecting sleeve; the airbag comprises an elliptical annular airbag bodyand an inflatable tube; the surgical instrument channel comprises a channel body and a handle; In the used state, the airbag body is inclined in the elastic connector body, and the proximal end of theinflatable tube extends from the connecting sleeve and is fixedly sealed by the fixing member; The channel body is inserted into the connecting sleeve and fixed and sealed by a fixing piece; The airbag body inflates and expands to support the elastic connector body; The elastic connector is also inflated. The device system of the invention has the advantages of simple structure, low cost, firm fixation, flexible operation and good stability, and creates conditions for the improvement of V-NOTES surgery.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a single-hole laparoscopic instrument system for V-NOTES operation. Background technique [0002] Natural orifice transluminal endoscopic surgery (NOTES) is an emerging minimally invasive surgical technique. V-NOTES refers to the operation of the body cavity through the natural orifice of the human body through the vagina by using the endoscope without incision on the body surface. . Compared with traditional laparotomy and laparoscopy, V-NOTES has the advantages of no abdominal wall injury, no visible surgical scar, less intra-abdominal adhesion, less surgical trauma, less postoperative pain, faster recovery, and ideal cosmetic effect. And there were no incision infection, incision hernia and other related complications caused by abdominal wall incision puncture point (transabdominal laparoscopy).
