Medical loop ligature device with quick resetting and recycling functions

Abstract

The invention discloses a medical loop ligature device with quick resetting and recycling functions, and belongs to the technical field of medical loop ligature devices. The medical loop ligature device comprises a rotary driving handle, a main rod, a loop ligature assembly, a pressing driving part, a handle and a transmission assembly, and a handle sleeve is rotatably mounted outside the main rod. According to the medical loop ligature device with the quick resetting and recycling functions, the movable loop ligature assembly is installed, in the rotating process of the transmission assembly, a threaded rod can be driven to rotate, the threaded rod can automatically drive the loop ligature assembly to move towards one side, patient tissues can be more effectively ligated into a loop ligature sleeve in the loop ligature assembly, meanwhile, a transmission gear in an external cutting knife storage sleeve can be engaged with a limiting transmission rack to rotate, so that an annular cutting knife which is engaged with the transmission gear and is provided with meshing teeth is driven to be sent out, the effect of synchronous cutting during loop ligature is achieved, the using effect of the loop ligature device is improved, and when the loop ligature sleeve is taken back, the annular cutting knife can be automatically and rapidly stored, and the next loop ligature on the tissue of a patient is not affected.

Description

technical field [0001] The invention belongs to the technical field of medical ligation devices, in particular to a medical ligation device with the function of quick reset and recovery. Background technique [0002] The ligation device is also a medical device for surgical operations. It can achieve the effect of ligation and resection of some patient tissues. It plays an important role in clinical medicine. One of the most important indicators for ease of use. [0003] Chinese patent discloses (CN201920305510.8) an automatic hemorrhoid ligation device, including a casing, a hemorrhoid cavity rod, a buckle part, a drive buckle part that is inserted into the hemorrhoid affected area, and a buckle drive assembly that is locked into the hemorrhoid. The locking component of the affected part and the controller that drives this hemorrhoid ligation device to automatically complete the ligation of hemorrhoids. The pressure interface is embedded in the casing to connect to an ext...
