Endoscopic biopsy forceps convenient for sampling

Abstract

The invention discloses endoscopic biopsy forceps convenient for sampling. The endoscopic biopsy forceps comprise a main tube; the main tube is of a hollow cylindrical structure; the left end and theright end of the main tube are open; and the top and the bottom of one end of the outer side wall of the main tube are each fixedly provided with a slave connecting block. By holding the main tube, blades stretch into a sampling tube and are adjusted in position, until the blade makes contact with a squeezed to-be-sampled tissue, the finger is put on a holding ring, the main tube is held to push the holding ring towards the sampling tube, the holding ring pushes a stretching rod, the stretching rod pushes a sliding column, a slave sliding block slides on a slave sliding groove, a main connecting strip is pushed to move outwards, the main connecting strip moves to push two slave connecting strips to move outwards, the two blades are opened, the holding ring is pulled again, the two blades are closed, and the to-be-sampled tissue is cut off by pushing and pulling the holding ring repeatedly in the way, so that the to-be-sampled tissue can be easily cut off.

Description

technical field [0001] The invention relates to the technical field of inner cavity, in particular to an endoscopic biopsy forceps which is convenient for sampling. Background technique [0002] Biopsy forceps are an indispensable tool for endoscopic examination to obtain pathological specimens. If contaminated biopsy forceps are used to obtain specimens, nosocomial infection will occur. Divided into ordinary biopsy forceps and thermal biopsy forceps, what is the biggest difference between ordinary biopsy forceps and thermal biopsy forceps, thermal biopsy forceps, it can be connected to high-frequency electricity, its function is to grasp tissue, can clamp polyps, can Appropriate hemostatic biopsy forceps are divided into two types according to the different parts used: one is suitable for the upper gastrointestinal tract, which is relatively short, and the other is suitable for the lower gastrointestinal tract and is relatively long. [0003] However, the existing biopsy f...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an endoscopic biopsy forceps that is convenient for sampling, which is capable of timely hemostasis at the sampled site, avoiding a large amount of bleeding, and can adjust the distance between the blade and the tissue to be sampled according to different operating environments , improves the utilization rate of the device, the tissue to be sampled can be easily taken out, saves time and other advantages, solves the problem of large wounds, easy bleeding, damage to the patient's body, and the blade cannot be adjusted according to different operating environments The distance from the tissue to be sampled, the utilization rate of the device is poor, and the sampled tissue cannot be taken out easily, which takes a lot of time
