Disposable biopsy forceps

Abstract

The invention relates to a disposable biopsy forceps, which at least comprise the following structures: a forceps head assembly which comprises at least two forceps heads of which the far ends can beoppositely opened or closed; a forceps seat, wherein the near end of the forceps head is connected with the far end of the forceps seat through a connecting piece; a control line, wherein the far endof the control line is connected with the near end of the forceps head assembly so as to drive the forceps head assembly to be opened or closed; a gasket, wherein the far end side of the gasket is connected with the forceps seat through the connecting piece, the near end side of the gasket is provided with two extension parts which are oppositely arranged and extend towards the near end, an extension channel is formed between the two extension parts, and the far end of the control line moves in the extension channel. The biopsy forceps have the technical effects of being simple in structure, stable and reliable.

Description

technical field [0001] The invention relates to a disposable biopsy forceps, belonging to a medical device used in a human body. Background technique [0002] Biopsy forceps are an indispensable tool for taking pathological specimens for endoscopy, and are usually used to collect living tissue samples in human body cavities such as the digestive tract and respiratory tract. If contaminated biopsy forceps are used to obtain specimens, nosocomial infections will occur, so disposable biopsy forceps are gradually recognized by people. During the use of disposable biopsy forceps, the following steps are usually required: actuate the control line through the driving module on the handle, and then drive the jaw assembly at the distal end of the biopsy forceps to open, and then drive the forceps head through an actuating tool such as an endoscope The components are aligned to take the tissue in the human cavity, and finally the jaw component is closed to clamp the tissue through th...

AI Technical Summary

Problems solved by technology

[0004] 1. In the existing disposable biopsy forceps, because the clamp head assembly and the proximal control line head are usually connected by a transition block or direct riveting, the clamp heads are easily misaligned, and the relative position of the two clamp heads is not easy to fix, and the position of the two clamp heads is not easy to fix after misalignment. It will be automatically corrected, and the moving structure in the biopsy forceps is easy to deviate. These problems may lead to tissue tearing caused by the misalignment of the forceps head when taking samples.

[0005] 2. In order to ensure the smooth opening and closing of the clamp head without misalignment, complicated welding is required for the connection point of the clamp head and the clamp head seat, which requires a lot of working hours and manpower. Due to the high welding requirements, the quality control of the biopsy forceps is increased. Difficulty, high defective rate

[0006] 3. The amount of forceps taken by existing biopsy forceps is not easy to control, and the amount of forceps taken is often too large, resulting in an increase in the risk of human injury
