Disposable cervical needle biopsy forceps with light source and using method of disposable cervical needle biopsy forceps

Abstract

The invention relates to disposable cervical needle biopsy forceps with a light source. The disposable cervical needle biopsy forceps comprise a shell and further comprise a sampling head and a transmission mechanism, wherein the sampling head consists of a quantifying mechanism, a sampling mechanism and a driving mechanism; the quantifying mechanism consists of a quantifying sleeve and a quantifying sleeve assembling stand; the sampling mechanism comprises a needle tube and a slice, a notch part is formed at the front end of the needle tube, the slice is fixed at the front end of the needle tube and is opposite to the notch part, and the rear end of the needle tube is detachably connected with a needle tube assembly stand; the driving mechanism consists of a secondary needle tube and a secondary needle tube assembly stand; the sampling mechanism, the driving mechanism and the quantifying mechanism are connected coaxially in sequence from inside to outside through the needle tube assembly stand, the secondary needle tube assembly stand and the quantifying assembly stand; the transmission mechanism consists of a connecting shaft with a locating piece, an elastic reset element, a transmission shaft, a fixing seat, a transmission rod and a switch. The disposable cervical needle biopsy forceps are rational in structure design, simple to machine and assemble, low in machining cost, and accurate and reliable in sampling quantity and cause little pain.

Description

technical field [0001] The invention relates to a disposable cervical puncture biopsy forceps with a light source and a using method thereof, belonging to the technical field of medical appliances. Background technique [0002] Biopsy forceps is an essential tool for gynecological examination. When a doctor or patient wants to perform pathological examination on the lesion, it can enter the patient's body through the biopsy forceps to clamp the tissue of the lesion for pathological examination for diagnosis. Sampling microtrauma through biopsy forceps, so it is very popular with doctors and patients. At present, when dilators are used clinically for gynecological examinations, the description of the lesion range is usually estimated based on experience, so there is a lack of more accurate measurement values, and the measurement results often have large errors and even misleading when compared with the actual lesion range The examination doctor's initial impression on the di...
