Continuous repeated sampling bronchoscope biopsy forceps

Abstract

The invention discloses a pair of continuous multi-sampling bronchoscope biopsy forceps, which comprises a round tube, a plurality of groups of independent axially pointing rope cavities are formed in the shell wall of the round tube, an upper forceps cover and a lower forceps cover are respectively hinged to the shell wall at the right end of the round tube, and a first shaft ring and a second shaft ring are respectively and rotatably mounted on the shell wall of the round tube close to the hinged ends of the upper forceps cover and the lower forceps cover; two groups of first shaft rings are coaxially and independently arranged in parallel in the front-back direction, a rotary shifting assembly is installed in the upper clamp cover, and a sampling device is installed in the portion, located on the left side of the rotary shifting assembly, of the circular pipe; the electric cutting element sheets are uniformly laid on the contact surface ends of the upper clamp cover and the lower clamp cover; the first wire rope penetrates through a group of independent rope cavities from the outside of the circular tube, is wound around the first shaft ring on the rear side by multiple circles and is connected with the middle part of the upper clamp cover; and the second wire rope penetrates through the group of rope cavities from the outer part of the circular tube, is wound around the second shaft ring for multiple circles and is connected with the middle part of the lower clamp cover.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a bronchoscope biopsy forceps for multiple continuous sampling. Background technique [0002] At present, during the sample sampling process of the bronchoscope, it is sometimes necessary to take multiple samples to ensure a wider range of sample monitoring and sampling areas, thereby improving the accuracy of pathological detection. However, most of the existing sampling devices can only sample once at a time, and a small amount of continuous sampling devices have less sample collection and storage capacity in the sampling process, so it is difficult to ensure multiple intubations in sequence and multiple sampling. , and then re-intubation sampling will still be performed. [0003] Therefore, those skilled in the art provide a bronchoscopic biopsy forceps with continuous multiple sampling to solve the problems raised in the above-mentioned background technology.
