Description
Technical field
This utility model relates to the Microendoscopic technical field of medical instruments, more particularly, relates to a kind of disposable use biopsy forceps with resetting-mechanism.
Background technology
In splanchnoscopy, biopsy forceps is the instrument of an indispensability, and when doctor or patient wished that diseased region carried out pathologic finding, it can enter in the patient body by endoscope, the tissue of gripping diseased region, for pathologic finding in order to make a definite diagnosis.Disposable use biopsy forceps is to sting by soft endoscopic forceps pincers road to get a kind of medical apparatus and instruments that living tissue is done the pathology analysis, and it mainly is comprised of binding clip, drag-line, slip ring, trocar sheath and handle.During operation, under endoscope monitoring, biopsy forceps enters the human body sampling point by endoscope channel, and the driving handle slip ring opens jaw, is close to sampled tissue, and pulling handle slip ring closes up jaw, pulls back outer tube, takes out sample pickup tongs.Endoscope's sampling is little because of misery, Wicresoft hinders, therefore deeply be subjected to doctor and patient's welcome.
At present, the operating mechanism that is applied to Microendoscopic medical apparatus and instruments (comprising apparatuses such as once using biopsy forceps, disposable use foreign body forceps, disposable use snare and disposable use cytology brush) generally is not with resetting-mechanism, when operation, must be by medical worker's operation, can reset, increase medical worker's labor intensity, prolong the time of operation technique, reduce the efficient that pincers are got, increased patient's misery.Simultaneously, refer to that the button slip ring is simple in structure, easy to use because of it, be widely used in the medical apparatus and instruments such as the disposable use foreign body forceps of Microendoscopic, disposable use snare, disposable use cytology brush.
Such as China Patent No. ZL200420023017.0, Granted publication day is on August 10th, 2005, the utility model name is called: a kind of biopsy forceps handle, this application case relates to a kind of biopsy forceps handle, there is an open slot at place, end near fixed handle, be provided with a joint in fixed handle, this joint is connected with an end of steel pipe steel wire.This application case has been avoided the asynergic movement of bourdon tube and steel pipe steel wire and the tractive resistance that produces to a certain extent.The weak point of this application case is: a kind of biopsy forceps handle of this application case is without resetting-mechanism, and its full operation by operator that resets realizes, has not only reduced operation efficient, returns the patient and has brought misery.
In addition, Chinese patent application numbers 201010211993.9, Shen Qing Publication day is on January 11st, 2012, invention and created name is: with the biopsy forceps of adjusting device, this application case relates to a kind of biopsy forceps with adjusting device, comprise caliper, the front end binding clip of caliper passes the end that soft pincers road is positioned at gastroscope, the activity of the clamp handle control biopsy forceps of the caliper other end, caliper and control wire are arranged side by side, one end of control wire is fixedly connected with the binding clip of biopsy forceps, and soft pincers road and clamp handle that the other end of control wire then stretches out gastroscope together are exposed on the external.The difficulty that can not accurately locate when this application case has solved existing biopsy forceps biopsy, rational in infrastructure, use flexibly, accurate quick, can arbitrarily adjust the front end flexibility, reaching the ideal position of sampling, but its weak point is: this biopsy forceps with adjusting device does not have resetting-mechanism yet, increase medical worker's labor intensity, prolonged the time of operation technique.
