Description

Biopsy sampling forceps convenient to operate

Technical Field

The utility model belongs to living tissue sampling instrument field, concretely relates to living tissue sampling forceps convenient to operation.

Background

Biopsy forceps are a medical instrument used in the treatment of the digestive tract of a human body, and are commonly used tools in endoscopy to enter a patient through an endoscopic forceps channel and to take a biopsy of a lesion for pathological examination to confirm diagnosis when a doctor or a patient desires to perform pathological examination of the lesion. The sampling forceps conventionally used in the market at present generally comprise a control part, a connecting part and a forceps cup part, wherein the two forceps cups are hinged with the connecting part, and the control part is connected with the connecting part and controls the opening and closing of the two forceps cups. The specific procedure for obtaining living tissue is as follows: the thumb is inserted into the thumb ring, the forefinger and the middle finger clamp the sliding handle, the closed forceps cups are inserted into the endoscope biopsy channel, when the closed forceps cups approach to a part needing biopsy, a doctor operates to open the two forceps cups, so that after the two forceps cups clamp living tissue, the two forceps cups are quickly lifted to tear the tissue, and the living tissue is obtained. Although the existing forceps can perform the function of taking a living tissue, the existing forceps have the following problems that 1. the extending length of the biopsy forceps is manually controlled, the forceps cup can only extend inwards slowly with great care and no matter when contacting with the tissue due to the long traction steel wire, and if the operation is performed quickly, ulcers or tumors can be damaged carelessly, even the forceps cup can touch to cause perforation and bleeding, the operation time is long, and the uncomfortable time of a patient is prolonged. 2. When in sampling, living tissues are obtained in a 'tearing' mode after clamping, peripheral tissues can be seriously damaged in the 'tearing' mode, large-area damage and bleeding are caused, and great pain is brought to a patient; furthermore, the living tissue obtained carelessly may fall off, which makes the patient feel bitter twice. 3. When medical staff operates the sliding handle to take a sample, the comfort is poor.
