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

Abstract

Provided is a surgical system for NOTES by which surgical invasion can be reduced. A surgical system for NOTES comprising a circular anastomosis device (1) wherein an anvil part (3) attached to a guide electrical wire (100) is connected to a main body (2) to be inserted into body tract and then inserted into a body tract (T) from a natural orifice (Ma) and, after cutting off a lesion site (T3) inthe body tract with a pair of linear cutters (558, 559) of a linear cutter / stapler (500) having been inserted from a body cavity (Mb), the cut ends are anastomosed together for the repair.

Description

technical field [0001] The present invention relates to a surgical system and a surgical method for resecting the lesion of a living body tube and making the cut ends coincide with each other, and in particular to a method that saves the large-scale living body surgery such as laparotomy performed in the past so as to reduce the number of surgical operations. Surgical system and surgical method for traumatic natural orifice 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 e...

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
