Minimally invasive surgery endoscopic extractor

Abstract

The invention discloses a minimally invasive surgery endoscopic extractor. The extractor comprises an outer cylinder tube, an inner cylinder tube is movably inserted into the outer cylinder tube, anda worm is rotationally connected between the inner walls of the outer cylinder tube; one end of the worm penetrates through the inner walls of the outer cylinder tube and extends to the outside to befixedly connected with a knob; a dial is arranged at the position, on one side of the knob, on the surface of the outer cylinder tube; the worm is meshed with a turbine, and a screw rod is fixedly inserted into an inner ring of the turbine; one end of the screw rod is rotationally connected with the inner walls of the outer cylinder tube, and the other end of the screw rod penetrates through the outer wall of the inner cylinder tube and extends to the inside to be fixedly connected with a limiting block; a first sliding block is in meshed and sleeved connection with the surface of the screw rod; the surface of the first sliding block is fixedly connected with the inner wall of the inner cylinder tube, and second sliding blocks are fixedly connected to the two ends of the outer surface of the inner cylinder tube; a T-shaped rod is inserted into the second sliding blocks. According to the extractor, the turbine, the worm and the dial are arranged, so that situation that the extending portion of a wire ring and an extraction bag are too long and influence the operation effects and efficiency is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of interventional equipment for minimally invasive surgery, in particular to an endoscopic object retrieval device for minimally invasive surgery. Background technique [0002] Minimally invasive surgery, as the name implies, is minimally invasive surgery, which refers to surgery performed using modern medical instruments such as laparoscopy and thoracoscopic surgery and related equipment. The advantages of minimally invasive surgery are small trauma, light pain, and quick recovery. It is the dream of every patient who needs surgery. Minimally invasive surgery makes this dream a reality. After the foreign body is removed, the human body needs to be taken out. Under the field of view of the endoscope, special tools are needed for taking it out. The existing extraction device generally inserts one end into the surgical wound, and releases the extraction bag by pushing the handle. However, in the process of pu...

AI Technical Summary

Problems solved by technology

The existing extraction device generally inserts one end into the surgical wound, and releases the extraction bag by pushing the handle. However, during the process of pushing the handle, it is necessary to observe the length of the entry through the detection head, but manual pushing cannot be performed accurately. Control the length of entry, so it affects the effect of the operation and prolongs the operation time, which cannot meet the ideal operation effect
