Description

Novel biopsy forceps for gastrointestinal disease diagnosis

Technical Field

The utility model relates to the field of medical treatment, especially, relate to novel biopsy forceps of intestines and stomach disease diagnosis.

Background

Endoscopy (gastroscope, enteroscope, colonoscope, etc.) is the main means for diagnosing gastrointestinal diseases, and in order to determine the nature of gastrointestinal lesions, partial tissues are often required to be clamped for pathological examination. The current clinical biopsy forceps have the following problems: 1. limited flexibility: the biopsy forceps used clinically at present are linear, the head is fixed, the limited direction can be changed only along with the rotation of the endoscope body and the head during operation, and tissues are not easy to clamp for parts (such as the cardia anus side, the ileocecal valve side and the like) which are small in lesion and difficult to reach by an endoscope; 2. the liquid specimen can not be retained, the clinical diagnosis usually needs to retain gastric juice and intestinal juice for assay to make definite diagnosis, but at present, only solid tissue can be retained under the endoscope, and the liquid around the pathological tissue can not be sucked. The above problems seriously affect the diagnosis of some diseases in endoscopy. Biopsy forceps are no doubt of the prior art. Prior art ZL 201721585473.8 discloses a biopsy forceps, but like this biopsy forceps, it is not easy to change direction and it is not easy to take multiple samples.
