Labial-gland biopsy device

Abstract

The invention provides a labial-gland biopsy device. The labial-gland biopsy device comprises a biopsy knife and a biopsy pulling hook which are hinged; the biopsy knife comprises a knife handle and aknife head, and the knife handle is fixedly connected with the knife head; the biopsy pulling hook comprises a pulling hook handle and a pulling hook end, the pulling hook end is fixedly connected with the pulling hook handle, and the end, away from the pulling hook end, of the pulling hook handle is hinged to the end, away from the knife head, of the knife handle. The biopsy knife and the biopsypulling hook which are hinged are unfolded into a long straight rod during using, the biopsy knife is arranged at one end, the biopsy pulling hook is arranged at the other end, and the long straightrod is conveniently used during operation; after operation is completed, the labial-gland biopsy device is cleaned and disinfected to be rotated and folded to be contained, storage space can be saved,and containing and storing are convenient. According to the labial-gland biopsy device, a labial-gland biopsy operation is completed through one tool, the preoperative preparation time of medical staffs is saved, one person can operate the labial-gland biopsy device, manpower and material resources are saved, operation is convenient, labial-gland biopsy is high in success rate, a wound is small,and pains of a patient are reduced. The labial-gland biopsy device is conveniently disinfected, cleaned and contained after operating, and is convenient to clinically use and popularize.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a lip gland biopsy device. Background technique [0002] Labial gland biopsy (labial glands biopsy) is the biopsy of lip glands, which is a pathological examination of partial lip gland lobule biopsy under local anesthesia for microscopic analysis. Lip gland biopsy is one of the important objective indicators for the diagnosis of Sjogren's syndrome, and the method is sensitive and specific. [0003] In the existing lip gland biopsy operation, after incising the lip mucosa and exposing the lip gland tissue, it is necessary to clamp the lip gland with tweezers, and then use a scalpel or scissors to cut off the root. When the tweezers are clamping the lip gland tissue, it is often difficult to grasp the strength. If the tweezers are too heavy, the tissue specimen will be squeezed, and if they are too light, they will easily fall off. After incision of the lip mucosa, t...

AI Technical Summary

Problems solved by technology

When the tweezers are clamping the lip gland tissue, it is often difficult to grasp the strength. If it is too heavy, it will squeeze the tissue specimen, and if it is too light, it will easily fall off.

After incision of the lip mucosa, the lip gland tissue the size of a grain of rice is arranged like a peeled grapefruit flap, and each lip gland tissue has a separate root pedicle, and the use of scissors or a scalpel to remove the lip gland root is often Inaccurate control of the strength will injure the surrounding tissues, which will increase the surgical wound

In addition, this method is complicated to operate, not only requires an assistant to assist in opening the lower lip of the patient, exposing the surgical site, but also cumbersome operation
