Description

A kind of multifunctional biopsy forceps

technical field

The utility model belongs to the technical field of medical equipment, in particular to a multifunctional biopsy forceps.

Background technique

At present, the size of ulcers and tumors under endoscopy is estimated by the naked eye, which is very inaccurate. The size of malignant ulcers is related to prognosis, and the size of tumors is related to EMR and ESD surgical methods under endoscopy. Therefore, more accurate measurements are needed. Ulcers and tumors need to be biopsied for pathological detection, so the biopsy forceps can be used as a scale to measure the size of the standard length of the front section of the biopsy forceps. Secondly, the detection rate of early gastrointestinal malignant tumors in China is currently lower than that in European and American countries. The use of dyes can increase the chance of early cancer detection and determine the scope of lesions. Therefore, the design of the biopsy forceps is equipped with dye nozzles, which can be sprayed with dyes. The design is a multifunctional biopsy forceps integrating biopsy forceps, ruler and nozzle.

Utility model content

The technical problem to be solved by the utility model is to provide a multifunctional biopsy forceps which integrates biopsy, measurement and dye spraying, which is convenient for measuring the lesion range and increasing the discovery of early cancer.

In order to solve the above technical problems, the technical solution adopted by the utility model is: a multifunctional biopsy forceps, including a handle, one end of the handle is provided with a handle ring, the other end of the handle is connected to the insertion arm, and the end of the insertion arm is provided with a forceps head; The handle is provided with a sliding handle, which is characterized in that: the handle is provided with a dye channel, the handle is provided with a dye inlet connected to the dye channel, and a protective cap is installed on the dye inlet; The insertion arm is provided with a dye nozzle connected to the dye channel in the handle, the end of the dye nozzle is provided with a spray head, and the spray head extends out of the insertion arm;

The front end of the insertion arm is sequentially provided with 6 scale marks, the interval between each scale mark is 0.5 cm, and the distance between the front end scale mark and the front end of the insertion arm is also 0.5 cm.

Further, the pliers head is composed of three jaws; a cavity is provided in the jaws, a connection seat is provided on the top of the cavity, and a toothed bottom connected to the connection seat is provided in the cavity. Connector.

Beneficial effects of the utility model: 1) The utility model has a simple structure, and the scale mark is used to measure the range and size of the lesion when taking the lesion tissue for pathological examination. ; 2) The biopsy forceps of the present utility model increases the nozzle spraying dye to increase the detection of early cancer, and is a multifunctional biopsy forceps integrating biopsy, measurement and spraying dye; 3) The utility model has a cavity set in the jaws And connecting seat, you can install toothed connecting body, easy to operate.
