Surgical system and surgical method for natural orifice transluminal endoscopic surgery (NOTES)

Abstract

Provide a system and method for use in NOTES so as to reduce surgical invasiveness. An insertion body that is connected by an anvil assembly and joined to a thin wire guide (electric guide wire), is inserted via a natural orifice into a hollow organ so as to incise and remove a diseased or defective site from the hollow organ by using a pair of (front-end / rear-end) linear cutters of a linear cutting / stapling device (linear stapler), after which the two cut ends of the tract are anastomosed and recovered by a circular anastomosis surgical stapler that is equipped with the system.

Description

technical field [0001] The present invention relates to a kind of surgical operation system which excises the lesion part of the living body tube and makes the cut ends coincide with each other, especially relates to a kind of surgical operation system which saves the large-scale living body operation such as laparotomy performed in the past so as to reduce the surgical injury. Surgical system for endoscopic endoscopic surgery (NOTES). Background technique [0002] At present, in surgical operations such as resecting the lesion of living tubes such as the digestive tract and anastomosing the severed end into a circular tube shape, for example, the lesion of intestinal cancer has to be resected from the outside by incision of the abdomen, and then removed from the outside. A surgical procedure in which two severed ends are joined to each other. In recent years, the following surgical method has been proposed, which has been promoted into practical use quite effectively: the ...

Problems solved by technology

[0015] Like this, although linear cutting / suture device and circular anastomosis device have taken various improvements and obtained continuous progress so far, although its constitution has realized from a natural opening (for example anus) will be used as the living body tube of circular anastomosis device The shaft assembly 1050 inserted into the main body is inserted into the living body tube, but it is necessary to use the thread to align the anvil after excision of the lesion of the living body intestine by the linear cutting / suturing device from the outside of the opening of the living body such as abdominal incision. The purse-bag banding near the cut end of the living body tube of the seat shaft 1104 and the trocar part, and the connection of the anvil part 1000 and the head 1061 through the anvil shaft 1104 and the trocar part are still required. performing a large vivisection

[0016] Therefore, while requiring a lot of time, labor and cost, there is a substantial problem that the operation damages the patient too much, such as a long treatment period.

[0017] In addition, although the circular anastomosis device in recent years has been praised as a device that "automatically anastomoses" both of the cut ends of the two lesions of the biopsy tube (for example, Japanese Patent Document 1), as long as it is necessary to cut the opening from the biopsy Externally, the purse-bag binding of the anvil shaft and the cut end of the living tube of the trocar part, and the connection of the anvil part 1000 and the head 1061 with a thread can not be correctly called "automatic". matching device
