Description

Angle-adjustable lung specimen extractor and working method thereof

Technical Field

The invention relates to the field of medical instruments, in particular to an angle-adjustable lung specimen extractor and a working method thereof.

Background

The pathological examination is a direct and effective examination method which collects small pieces of tissues of a pathological part of an organism by an operation method, carries out the pathological histological examination, finds out the evidence of pathological change and is matched with clinic to make a confirmatory diagnosis on diseases.

In practical operation, the fetching bag is a matched product of an operating instrument under a thoracoscope and is used for taking a biopsy sample out of an operating area during operation. For example, the notice number of the publication authorized by the national intellectual property office 2020.07.31 is CN21131191U, which is named as "specimen fetching bag for endoscopic surgery", and discloses that in the current clinical surgery process, after a specimen is cut off, an outer sheath tube with the built-in specimen fetching bag is inserted into a surgery part through a poking card, and then the article fetching bag is pushed out of the outer sheath tube and stretched under the push of the inner pushing tube. Then the doctor puts the specimen into the fetching bag, pulls the inner push tube backwards, tightens the bag opening, is pulled back into the outer sheath tube and moves out of the body along with the outer sheath tube.

However, because the thoracic space is small, the excised lung specimen tissue is large, and after the object taking bag is opened, because the angle is not adjustable, the angle for putting the specimen into the object taking bag is limited, thereby increasing the operation difficulty; and the specimen is easy to slide out of the object fetching bag, so the operation is inconvenient.
