a biopsy forceps

Abstract

The invention discloses a biopsy forceps, comprising a mounting and fixing part, a clamp head assembly and a control assembly; the clamp head assembly includes a first forceps cup and a second forceps cup; the first forceps cup and the second forceps cup pass through the mounting and fixing part The first pliers cup is formed with a first cutting part; the second pliers cup is formed with a second cutting part; the second cutting part is used to abut each other when the first pliers cup and the second pliers cup When it is used, it cooperates with the first cutting part to cut off the living tissue; the control assembly is connected with the fixing part, and is used to control the opening and closing of the first forceps cup and the second forceps cup. The invention can prevent large-area damage to surrounding tissues during the sampling process, reduce bleeding probability, and improve extraction accuracy.

Description

technical field [0001] The invention relates to a sampling forceps, in particular to a biopsy forceps. Background technique [0002] Endoscopic examination such as gastroscopy and colonoscopy is one of the most commonly used clinical examination methods because it can directly observe the lesions of the gastrointestinal tract and other parts. In endoscopic examination, sampling forceps is a commonly used tool. When doctors or patients wish to carry out pathological examination on the lesion, it can enter the patient's body through the forceps channel of the endoscope to clamp the living tissue of the lesion for future use. Pathological examination for diagnosis. [0003] The sampling forceps that are routinely used in the market generally include a control assembly, a connecting piece and two pliers cups, wherein the two pliers cups are hinged on the connecting piece, and the control assembly is installed on the connecting piece and controls the opening and closing of the t...

Problems solved by technology

[0003] The sampling forceps that are routinely used in the market generally include a control assembly, a connecting piece and two pliers cups, wherein the two pliers cups are hinged on the connecting piece, and the control assembly is installed on the connecting piece and controls the opening and closing of the two pliers cups; The specific operation procedure is as follows: Insert the two forceps cups into the endoscopic biopsy channel, open the two forceps cups, approach the site to be biopsied and close the two forceps cups to clamp the living tissue, then quickly pull the two forceps cups to "tear" the tissue, to obtain living tissue; although the existing sampling forceps can achieve the function of obtaining living tissue, the existing sampling forceps obtain living tissue by "tearing" after "clamping", this "tearing" method, It will seriously damage the surrounding tissue, cause a large area of ​​damage and bleeding, and bring great pain to the patient; moreover, this "tearing" method of obtaining tissue often requires rapid pulling and a large force at the same time. In this case, there is a high possibility of inclination and lateral displacement between the cups of the forceps, which will cause deviations in the tissue extraction layer, resulting in inaccurate tissue extraction, thereby affecting the accuracy of diagnostic results
