Example Embodiment

[0040] Example 1

[0041] See figure 1 , figure 1 It is a schematic diagram of the composition of the single port laparoscopic instrument system used in the V-NOTES operation of the present invention. The single-hole laparoscopic instrument system for V-NOTES surgery includes: an elastic connector 1, an airbag 2, a plurality of surgical instrument channels 3, and a plurality of fixing members 4.

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

Example Embodiment

[0054] Example 2

[0055] The single-port laparoscopic instrument system for V-NOTES surgery of this embodiment is the same as the single-port laparoscopic instrument system for V-NOTES surgery described in Embodiment 1, except for the structure of the elastic connector.

[0056] See Figure 7 , Figure 7 It is another schematic diagram of the structure of an elastic connector. The elastic connecting piece 1 includes an elastic connecting piece body 11 and five connecting sleeves 12. The elastic connector body 11 in the inflated state has a tubular structure, the distal end is open, and the proximal section is connected and communicated with the five connecting sleeves 12. The proximal end of the connecting sleeve 12 is open. The elastic connecting piece 1 is a structure in which both the distal end and the proximal end are open. 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...

Example Embodiment

[0058] Example 3

[0059] The single-port laparoscopic instrument system for V-NOTES surgery in this embodiment is the same as the single-port laparoscopic instrument system for V-NOTES surgery described in Embodiment 1, except for the structure of the surgical instrument channel.

[0060] See Figure 8 , Figure 8 It is another schematic diagram of the channel structure of surgical instruments. The surgical instrument channel 3 includes a channel body 31 and a handle 32. The passage body 31 has a round tube shape, and the proximal end is connected with the handle 32. The handle 32 is a prism with a square cross-section, and the side length is larger than the inner diameter of the channel body 31. A surgical instrument channel entrance 321 is provided in the center of the proximal end surface of the handle 32, 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 integrally for...

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).
