Embodiment Construction

[0038] The technical content of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] like Figure 1 to Figure 3 As shown, the continuous sampling biopsy forceps provided by the present invention includes a clamp head support 1 and two forceps heads 2a and 2b. Among them, such as image 3 As shown, the pliers head 2a and the pliers head 2b are respectively hinged on the inside of the front end of the pliers head bracket 1 through independent connecting columns 3a and 3b, so that between the two connecting columns 3a and 3b, that is, between the two pliers heads 2a and 3b A space 6 for accommodating a plurality of samples is formed between 2b. Rivets or pins can be used to connect the columns 3a and 3b. The continuous sampling biopsy forceps also includes a sampling needle 4 whose bottom is arranged on the platform 12 of the forceps head support 1. The sampling needle 4 extends forward from th...

Abstract

The invention provides continuous-sampling biopsy forceps. The continuous-sampling biopsy forceps comprise a forcep head support and two forcep heads. The two forcep heads are respectively hinged to the inner side of the front end of the forcep head support through independent connecting columns, and therefore space for containing a plurality of samples is formed between the two forcep heads; in addition, a sampling needle extending towards the portion between the two forcep heads is arranged on a platform of the forcep head support, so that the multiple samples obtained through continuous sampling are sequentially arranged on the sampling needle, it is guaranteed that the multiple samples obtained through continuous sampling can not slide down or be lost, and the continuous sampling effect is guaranteed. By means of the continuous-sampling biopsy forceps, continuous sampling of a focus and a biopsy can be completed in a short time only through once forcep feeding-discharging operation, sampling operation difficulty is lowered, sampling time is greatly shortened, and pains of a patient can be reduced.

Description

technical field [0001] The invention relates to a biopsy forceps, in particular to a biopsy forceps capable of continuous sampling, belonging to medical instruments. Background technique [0002] Biopsy forceps is a tool used to bite and sample the lesions in the abdominal cavity of the human body, and is generally used in conjunction with an endoscope. In the endoscopic examination, when pathological examination of the lesion is required, the biopsy forceps are sent into the patient's body through the endoscopic forceps channel, and the tissue of the lesion is clamped. Sampling through biopsy forceps is less painful and traumatic, so it is very popular among doctors and patients. [0003] Biopsy forceps are generally composed of a clamp head assembly, a slender cable, an equally slender elastic outer tube that covers the outside of the cable, and a handle. One end of the cable is connected to the four-bar linkage in the clamp head assembly, and the other end is connected t...
