Abstract

The invention provides an endoscope system, which can fix a pick-up device picking up an image in a body cavity in a wide range without cutting a body wall and can carry out a surgery using the endoscope with less infringement and no damages. The endoscope system (1) is provided with a camera (5) which picks up an image inside the body cavity, a camera side magnet (55) and a fixing magnet (23) connected on the camera (5) and fixing the camera (5) inside the body cavity by holding an abdominal wall (30) from different surfaces (30s, 30i) of the abdominal wall (30), and a second CCU (6) controlling the camera (5).

Description

technical field [0001] The present invention relates to an endoscope system including an imaging device that can observe the inside of the abdominal cavity over a wide range and is fixed inside the abdominal wall. Background technique [0002] In recent years, in order to reduce the invasiveness of the patient, laparoscopic surgery is performed without opening the abdomen. In this surgery, the endoscope for observation is guided to the trocar in the body cavity and the treatment instrument is guided to the treatment site. The trocar punctures the patient's abdomen, and the treatment is performed while observing the treatment device and the treatment site with an endoscope. [0003] For example, in Patent Document 1 figure 1 ~ Fig. 4 shows a trocar that fixes the distal structural part on the abdominal wall by operating the operation knob while pressing the side part of the distal structural part to the abdominal wall, and at the same time makes the distal structural part S...
