A kind of thoracoscopic extraction device

Abstract

A thoracoscope extraction device, comprising an outer sheath rod, an inner sheath rod, an elastic wire loop and a specimen collection bag, the inner sheath rod is provided with a through hole, and the first end of the outer sheath rod is provided with a fastening end. , the doctor holds the fastening end, extends the second end of the outer sheath rod into the patient's body, and pushes the inner sheath rod to move along the length of the through hole, so that the second end of the inner sheath rod is removed from the through hole of the second end of the outer sheath rod. During this process, the elastic wire loop will gradually separate from the through hole, so that the end connecting the specimen collection bag and the elastic wire loop is supported to form an opening. At this time, the part of the specimen collection bag is still in a folded state; further, The doctor connects the air supply part and the air inlet end through a catheter, the air supply part injects gas into the air inlet end, and the gas is transmitted along the ventilation pipe to the exhaust port and enters the film strip, so that the film strip gradually recovers from the first state to In the second state, when the folded part of the specimen collection bag is fully supported, tissue and organ extraction can be performed in the patient.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a thoracoscopic extraction device. Background technique [0002] In the process of performing thoracoscopic surgery, the resected tissue and organ samples need to be taken out from the patient's body through a take-out device. A utility model patent with application number 200920086638.6 proposes an endoscopic surgery take-out device. The specimen collection bag of the take-out device is Before use, it is shrunk in the outer sheath rod as a whole, and after the extractor is inserted into the patient's body, the specimen collection bag is controlled to protrude through the inner sheath rod to collect tissue and organ samples; The material of the collection bag is too soft. After the opening of the bag is opened, the bag body is still folded and closed, which makes it difficult to take the specimen and prolongs the operation time. The resected tissues and organs in the m...

[0002] In the process of performing thoracoscopic surgery, the resected tissue and organ samples need to be taken out from the patient's body through a take-out device. A utility model patent with application number 200920086638.6 proposes an endoscopic surgery take-out device. The specimen collection bag of the take-out device is Before use, it is shrunk in the outer sheath rod as a whole, and after the extractor is inserted into the patient's body, the specimen collection bag is controlled to protrude through the inner sheath rod to collect tissue and organ samples; The material of the collection bag is too soft. After the opening of the bag is opened, the bag body is still folded and closed, which makes it difficult to take the specimen and prolongs the operation time. The resected tissues and organs in the middle specimen bag are easy to fall out from the mouth of the bag, and the doctor needs to fish again, which reduces the success rate of the operation
