Mucous membrane tractor

Abstract

The invention discloses a mucous membrane tractor comprising an endoscope fixing part, an instrument lifting part, a swinging arm and a traction part, wherein the endoscope fixing part can be installed at a distal end head of an endoscope; the instrument lifting part can be used for installing a surgical instrument; one end of the swinging arm is movably connected with the endoscope fixing part, and the other end of the swinging arm is movably connected with the instrument lifting part; and the distal end of the traction part is connected with the instrument lifting part. The technical schemeprovides endoscopic surgeons a method for controlling more instruments to be used in a matching way by utilizing the traditional endoscope, meets requirements on multiple-instruments matching operation of the surgeons to a certain extent, achieves certain effects of reducing labor intensity of the complex and time-consuming surgeries encountered currently, such as ESD (Endoscopic Submucosal Dissection) and the like, greatly shortening surgery time and improving safety and operability, facilitate popularization of some complex and time-consuming surgeries to primary hospitals and plays the role of relieving the conditions of poor access to and high cost of medical treatment at present to a certain extent.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a mucosal retractor used in endoscopic surgery that can control the position or posture of surgical instruments. Background technique [0002] Endoscopes have been used to diagnose and treat diseases for more than 50 years. Most of them are single-channel endoscopes. However, with the continuous development and improvement of endoscopic surgery techniques, a single instrument can no longer satisfy the doctor's control over the instrument. Doctors are eager to use the existing endoscope to realize that two or more instruments can cooperate with each other to adapt to complex and difficult operations, so that the operation can be completed more safely and quickly. [0003] Most of the commonly used endoscopes have only one hole for passing instruments. During the operation, it is like a person working with only one hand. There is a lack of corresponding cooperation. Som...

[0002] Endoscopes have been used to diagnose and treat diseases for more than 50 years. Most of them are single-channel endoscopes. However, with the continuous development and improvement of endoscopic surgery techniques, a single instrument can no longer satisfy the doctor's control over the instrument. Doctors are eager to simply use the existing endoscope to realize that two or more instruments can be used in conjunction with each other to adapt to complex and difficult operations, so that the operation can be completed more safely and quickly

[0003] Most of the commonly used endoscopes have only one hole for passing instruments. During the operation, it is like a person working with only one hand. There is a lack of corresponding cooperation. Some slightly complicated actions need to be broken down into many steps to complete, such as mucosal peeling. Surgery that requires complex movements increases the threshold of surgery and is not easy to popularize. The long operation time increases pain for patients

At present, there is also a double-channel endoscope that can pass two instruments at the same time, but its cost is relatively high. The number of hospitals is very small, and only a few large hospitals have it. Small and medium-sized hospitals have not popularized some difficult and complicated endoscopic operations. small hospital promotion
