Description
Technical field
This utility model relates to a kind of medical examination operating theater instruments, the biopsy forceps in a kind of pincers road can reach minimum bending radius by endoscope time that is used for specifically that endoscope takes a sample.
Background technology
At present, splanchnoscopy has been widely used in clinical as a kind of aided diagnosis method.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 the speculum forceps road, the tissue of gripping diseased region, for pathologic finding so that make a definite diagnosis.By painful little, the Wicresoft's wound of endoscope's sampling, so be subjected to doctor and patient's welcome deeply.
Biopsy forceps generally is made up of binding clip assembly, elongated drag-line, same elongated be enclosed within drag-line outer elastic outer pipe and handle component, one end of drag-line links to each other with quadric chain in the binding clip assembly, the other end links to each other with flexible handle on the handle, one end of elastic outer pipe links to each other with the binding clip assembly, and the other end also links to each other with handle.Push away, draw flexible handle to drive drag-line, drag-line drives the quadric chain action, and two symmetrical clamps that quadric chain drives on the binding clip assembly are realized opening and closing, thereby take out suspect tissue external from gastroscope.
Crooked in order to guarantee not produce after binding clip is opened, existing biopsy forceps all has one to work the rigid attachment part that is connected with guide effect in the drag-line and the junction of binding clip assembly, the end that drag-line stretches in the rigid attachment part with pull bar is fixedly connected, the other end of pull bar is sleeved on the guiding rivet again, connector stretches out the part that the binding clip seat enters elastic outer pipe and play the guiding role, but the length of the rigid section that extended simultaneously.Need be when the doctor checks the pathological changes at some position with the endoscope head bending, sampling if desired, biopsy forceps will be by the pincers road of endoscope head bending, when bending radius hour, this rigidity segment length's biopsy forceps just is difficult to pass through, the doctor need treat endoscope's straightening to seek diseased region again after biopsy forceps passes through, and has increased work difficulty.
Summary of the invention
The purpose of this utility model provide a kind of can guarantee that the biopsy forceps binding clip is not crooked and trafficability characteristic is good can reach minimum bending radius by endoscope the time the biopsy forceps in pincers road, long to solve the rigid element that existing biopsy forceps exists, by the problem of bend difficulty.
The technical solution of the utility model is:
A kind of biopsy forceps of the pincers road can reach minimum bending radius by endoscope the time, comprise the binding clip assembly, drag-line, elastic outer pipe, Handleset, drag-line is sleeved in the elastic outer pipe, one end of drag-line and elastic outer pipe respectively with Handleset in flexible handle link to each other with core bar, the other end links to each other with the binding clip assembly, a quadric chain is installed in the binding clip assembly, left side binding clip, right binding clip is installed in the guiding slot port on the binding clip seat by fixing rivet as the assembly of quadric chain, and can rotate around fixing rivet, two connecting rods in addition in four link assemblies link to each other with the guiding rivet, connector is arranged in guiding slot port, the one end links to each other with the guiding rivet, the other end links to each other with drag-line, it is characterized in that in elastic outer pipe, be installed with the guide spring pipe on one section that drag-line links to each other with connector, the end corresponding to the Handleset direction of guide spring pipe stretch out the binding clip seat outer and with the elastic outer pipe matched in clearance.
Above-mentioned connector can be a steel pipe, and an end of steel pipe is sleeved on the guiding rivet after flattening punching, and an end of drag-line stretches in the other end of steel pipe, and fixedlys connected with steel pipe, and an end of guide spring pipe is fixed near on the drag-line of this end of steel pipe.The installing hole that the length of the steel pipe end that steel pipe links to each other with drag-line when closed with binding clip can not exceed on the binding clip seat exceeds outward.
Above-mentioned connector also can be the soft rope of a steel wire, the soft rope of steel wire is walked around into the U type from the guiding rivet, open two ends are passed from the guide spring pipe, and the guide spring pipe is fixed in guiding rivet place, and the soft rope of steel wire is merged into one after by the guide spring pipe and is connected with drag-line.
The beneficial effects of the utility model:
1, existing biopsy forceps binding clip parts have been solved by the comparatively difficult problem in crooked pincers road.
2, the guide spring pipe had both had certain rigidity, under static state, can guarantee the drag-line that is fixedly linked with it can be in elastic outer pipe moving linearly (gap between guide spring pipe and the elastic outer pipe is less), has certain flexibility again, guarantee that it at the volley can be crooked with elastic outer pipe, thus can be easily by crooked pincers road.
3, simple in structure, easily manufactured.
