Disposable cervical biopsy forceps

Abstract

The invention relates to disposable cervix aspiration biopsy forceps, which comprise a shell, a sampling head and a transmission mechanism, wherein the sampling head consists of a quantitation mechanism, a sampling mechanism and a driving mechanism; the quantitation mechanism consists of a quantitation sleeve and a quantitation sleeve assembling seat; the sampling mechanism comprises a needle tube and a slice, wherein the front end of the needle tube is provided with a notch part; the slice is fixedly arranged on the front end of the needle tube and is opposite to the notch part; the rear end of the needle tube is detachably connected with a needle tube assembling seat; the driving mechanism consists of an auxiliary needle tube and an auxiliary needle tube assembling seat; the sampling mechanism, the driving mechanism and the quantitation mechanism are successively coaxially connected from inside to outside through the needle tube assembling seat, the auxiliary needle tube assembling seat and the quantitation sleeve assembling seat; the transmission mechanism consists of a connecting shaft with a positioning element, an elastic resetting element, a transmission shaft, a permanent seat, a transmission rod and a switch. The disposable cervix aspiration biopsy forceps have the advantages of reasonable structure design, simpleness in processing and assembling, low processing cost, accurate and reliable sampling amount, and causes little pain.

Description

technical field [0001] The invention relates to a disposable cervical puncture biopsy forceps, 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 diagnosis of the lesion, and due to the limited f...
