In general, a medical endoscope is a medical device that is inserted into an organ, body cavity, or the like so that the inside of the endoscope can be seen without directly performing surgery. Unlike other medical imaging devices, the endoscope is inserted directly into the body, It has the advantage of observing the shape and condition of the organ and body cavity.

Such an endoscope is provided with a biopsy function for collecting body tissues in addition to a function of observing the body organs and body cavity of the body, and histologically examining the body tissues recovered from the endoscope to detect the presence or the progress of the disease To be diagnosed.

For this purpose, the endoscope has a biopsy channel in which a biopsy forceps for inserting a biopsy force for collecting a body tissue inside the insertion section is formed along the longitudinal direction of the insertion section, and a biopsy forceps is inserted into the biopsy channel through the biopsy channel In vitro, the operator manipulates the biopsy forceps to collect the body tissue. Then, the biopsy forceps can be taken out of the biopsy channel and the tissue can be recovered from the forceps.

The biopsy forceps, which is an endoscopic treatment instrument, is operated by operating a forceps fixed to the distal end of the endoscope to open and close the endoscope. Thus, the forceps is generally used to operate an end effector It is a configuration that is required to use the operator ' s thumb.

Various types of endoscopic forceps have been developed and used. A representative example of the endoscopic forceps will be described with reference to FIG.
