Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, and more specifically to a biopsy hemostatic forceps. Background Art

[0002] Biopsy forceps are also called biopsy forceps. They are mainly used to perform biopsies, which is to remove small tissue samples from the body for pathological examination; this examination helps diagnose many diseases, including cancer, inflammation and infection. Biopsy forceps are usually used with the assistance of endoscopes or other medical devices. Doctors will guide them to a specific location in the body and then use biopsy forceps to clamp tissue samples.

[0003] The Chinese patent authorization announcement number is: CN213606551U, which provides a biopsy forceps. This patent sets a left clamp and a right clamp at the top to be hinged to each other to form a jaw opening toward the operating component. The operating component can peel off the tissue by controlling the push-pull action of the clamp head. The jaw is set to the upper end, and the tissue is obtained by pushing and pulling. There is no need to change the direction of the clamp head, that is, the tissue can be peeled off, and it is not easy to slip, so as to avoid the tissue from escaping from the jaws, thereby improving the efficiency of obtaining tissue; further, the connection between the operating component and the clamp head and the way in which the operating component controls the opening and closing of the clamp head are similar to an "umbrella" shape. The connecting parts are respectively connected to the lower ends of the upper clamp and the lower clamp. By giving the push-pull force to the push-pull part, the angle formed between the two connecting rods is controlled, so that the push-pull force acts more evenly to control the opening and closing of the clamp head. The structure is simple, and the clamp head is more stable in cutting, and the diseased tissue is not easy to slip out of the clamp head during the cutting process.

[0004] However, the biopsy forceps mentioned in the above patents are made of relatively hard or metal materials, which can easily cause scratches to patients or sample tissues during use, and there is no guarantee during use. Utility Model Content
