Digestive endoscopy biopsy cap

Abstract

The invention discloses a digestive endoscopy biopsy cap. The digestive endoscopy biopsy cap comprises a rectangular sleeve fixedly arranged at the end part of an endoscope, first through grooves areformed in the two sides, close to the top, of the rectangular sleeve; the inner walls of the first through grooves are connected with sealing plates in a sliding manner; grooves are formed in the upper surfaces, close to the opposite ends, of the two sealing plates; the two grooves can form a complete circular-truncated-cone-shaped groove, circular truncated cone blocks are movably connected to the inner walls of the grooves, through holes are formed in the upper surfaces of the circular truncated cone blocks, lifting pipes are fixedly connected to the upper surfaces of the circular truncatedcone blocks through the through holes, and biopsy needles are connected to the inner walls of the lifting pipes in a sliding mode. According to the invention, the above structures are matched for use;the digestive endoscopy biopsy cap can solve the problems that in the actual use process, due to the fact that during biopsy operation, instruments such as a biopsy needle intervene through the biopsy cap, the sealing performance of a traditional biopsy cap is prone to being reduced, substances such as body fluid in the internal environment of a patient are sprayed out, the operation environmentand the instruments are polluted, and inconvenience is brought to operation of doctors.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a digestive endoscope biopsy cap. Background technique [0002] Biopsy, the full name is biopsy, also known as surgical pathological examination, referred to as "external examination"; it refers to the technique of taking out diseased tissue from the patient's body by cutting, clamping or puncturing for pathological examination in response to the needs of diagnosis and treatment ; It is the most important part of diagnostic pathology. It can make a clear histopathological diagnosis for most of the cases submitted for inspection, and it is used as the final clinical diagnosis. The biopsy cap is used on the biopsy port of the endoscope to play a sealing role; when the biopsy operation is not performed, it is often in a sealed state to stabilize the intraluminal air pressure of the digestive tract. During the biopsy operation, biopsy needles and other instruments Interven...

AI Technical Summary

Problems solved by technology

The biopsy cap is used on the biopsy port of the endoscope to play a sealing role; when the biopsy operation is not performed, it is often in a sealed state to stabilize the air pressure in the digestive tract. During the biopsy operation, biopsy needles and other instruments Intervention through the biopsy cap, but it is easy to reduce the sealing performance, so that the body fluid and other substances in the patient's internal environment are sprayed out, polluting the surgical environment and instruments, and causing inconvenience to the doctor's operation; for this reason, we propose a biopsy cap for digestive endoscopy
