Intelligent nasopharynx biopsy forceps

Abstract

The invention discloses intelligent nasopharynx biopsy forceps. The intelligent nasopharynx biopsy forceps comprise a forceps rod, a fixing forceps stem, a movable forceps stem, a connecting seat, a compressing spring, fixing rings, an air bag, a forceps head, a clamping head, a sleeve, a front fixing plate, a sleeving rod, a traction pull rope, a pull wire, a pulley, a tension spring, a line pipesleeve, a limiting plate, a lotion spraying hole, a lotion suction hole, a camera, communication pipelines, a baffle plate and an air bag connecting pipe. The intelligent nasopharynx biopsy forceps have the beneficial effects that the traction pull rope and the pull wire are arranged to pull the clamping head, so that the clamping head is conveniently controlled to be opened and closed, the clamping head is distributed in the shape of a lotus flower pedal, and when being closed, the clamping head forms the surrounding shape to guarantee living tissue to be taken down; the camera can convey nasopharynx images to an external display terminal, so that medical personnel can conveniently perform operations; the lotion spraying hole and the lotion suction hole are formed, so that parts where living organisms need to be taken are flushed; and inflation is performed on the inner part of the air bag, so that the air bag is expanded, the nasopharynx parts can be expanded, operations are convenient, the nasopharynx parts can be sealed, and flushing liquid can be prevented from flowing out.

Description

technical field [0001] The invention relates to a biopsy forceps, in particular to an intelligent nasopharyngeal biopsy forceps, belonging to the technical field of medical instruments. Background technique [0002] Nasopharyngeal biopsy is a commonly used method to confirm nasopharyngeal lesions, especially nasopharyngeal malignant tumors. Since my country is one of the areas with a high incidence of nasopharyngeal carcinoma, it is necessary to be familiar with the anatomy of the nasopharynx and the examination of nasopharyngoscopy in clinical work , Master the method of nasopharyngeal biopsy. [0003] Nasopharyngeal biopsy methods include transoral nasopharyngeal biopsy and transnasal nasopharyngeal biopsy. In nasopharyngeal biopsy via nasal cavity, in addition to pharyngeal spray to anesthetize the nasopharyngeal cavity, surface anesthesia is also required in the nasal cavity, and then the nasopharyngeal biopsy forceps are directly extended from the anterior nostril of th...

AI Technical Summary

Problems solved by technology

[0004] At present, there are two types of nasopharyngeal biopsy forceps used in nasopharyngeal biopsy through the nasal cavity. One is a raised front end. Because of the raised front end of this type, the patient will feel pain and discomfort when entering the nasal cavity. If the patient's nasal cavity Stenosis, variation or deformity will cause inaccessibility or unbearable pain; one is a straight front end, which patients feel less pain and discomfort when entering the nasal cavity, but after reaching the nasopharyngeal cavity, the operability is relatively poor, and the position More partial tumors are not easy to clip
