Abstract

The utility model relates to disposable biopsy forceps with measuring function, comprising a manipulating handle and a forceps head device, wherein the manipulating handle consists of an operation rod, an external pipe and a sliding ring; the sliding ring is movably sheathed on the manipulating rod; the external wall of the manipulating rod, close to the right end, is provided with a steel wire rotation control roller; the right end of the manipulating rod is connected with the forceps head device by the external pipe; the forceps head device comprises a forceps head assembling rack; the position on the forceps head assembling rack, close to the right end, is provided with an upper forceps head and a lower forceps head which are hinged with the forceps head assembling rack; the left ends of the upper forceps head and the lower forceps head are connected with the steel wires; and the steel wires sequentially pass through the external pipe, the manipulating rod and the steel wire rotation control roller and are connected with the sliding ring. The disposable biopsy forceps have the benefits that the structure is simple and novel, the rotating of the forceps heads can be controlled and operated conveniently as the steel wire rotation control roller is arranged on the manipulating handle; in the gastroscope or enteroscope examination process, one part of the lesion tissues can be removed for assay, and the size and scope of the pathological change can be measured simultaneously.

Description

The disposable biopsy forceps that has measurement function

Technical field

This utility model relates to medical apparatus and instruments, relates in particular to a kind of disposable biopsy forceps that has measurement function.

Background technology

In recent years, in clinical medicine is checked, splanchnoscopy has obtained extensive use as a kind of aided diagnosis method, when certain diseased region is checked in to the patient body, biopsy forceps can stretch in the body by the speculum forceps road, the gripping pathological tissues, take a sample by endoscope, Wicresoft hinders, painful little, so splanchnoscopy is a kind of well received diagnostic method, the binding clip assembly of endoscopic biopsy pincers commonly used at present is mainly by the binding clip frame, two steel wires that one end is connected with stick, and two the binding clips formations hinged with the binding clip frame, the other end of steel wire is connected with two binding clips respectively, such endoscopic biopsy wrench structure is stable, practical, but at present existing endoscopic biopsy pincers do not have the function of measuring the pathological changes size, and also the binding clip of endoscopic biopsy pincers can not rotate, operation inconvenience brings very big misery to patient simultaneously when checking.

The utility model content

The purpose of this utility model provides a kind of disposable biopsy forceps that has measurement function, has the function of measuring the pathological changes size, and binding clip can rotate as required, and is easy to operate, to overcome the problems referred to above that existing endoscopic biopsy pincers exist.

The purpose of this utility model is to be achieved through the following technical solutions: a kind of disposable biopsy forceps that has measurement function, comprise operating handle and binding clip device, described operating handle is by stick, outer tube and slip ring constitute, wherein slip ring is enclosed within on the stick movably, be provided with steel wire Spin Control roller near the right-hand member place on the outer wall of stick, the right-hand member of stick connects the binding clip device by outer tube, the binding clip device comprises the binding clip installing rack, be provided with upper grip head and the lower pliers head hinged near the right-hand member place on the binding clip installing rack with the binding clip installing rack, the left end of upper grip head and lower pliers head all is connected steel wire, and steel wire passes outer tube successively, the inside of stick and steel wire Spin Control roller also is connected with slip ring.

The upper surface of described upper grip head and the lower surface of lower pliers head are evenly distributed with five chequered with black and white graduation marks respectively, and the width of graduation mark is 1mm.

The beneficial effects of the utility model are: simple in structure, novel, has steel wire Spin Control roller on the operating handle, can control the rotation of binding clip, easy to operate, has the function of measuring the pathological changes size, when doing gastroscope or enteroscopy, can take off part chemical examination to pathological tissues, also can measure the size and the scope of pathological changes simultaneously.

With reference to the accompanying drawings this utility model is described in further detail below.

Fig. 1 is the described structural representation that has the disposable biopsy forceps of measurement function of this utility model embodiment; Fig. 2 is the structural representation of the binding clip device of the described disposable biopsy forceps that has a measurement function of this utility model embodiment; Fig. 3 is the structural representation of the upper grip head of the described disposable biopsy forceps that has a measurement function of this utility model embodiment; Fig. 4 is the structural representation of the lower pliers head of the described disposable biopsy forceps that has a measurement function of this utility model embodiment.

Among the figure: 1, operating handle; 11, stick; 12, outer tube; 13, slip ring; 14, steel wire Spin Control roller; 2, binding clip device; 21, binding clip installing rack; 22, upper grip head; 23, lower pliers head; 24, steel wire; 3, graduation mark.

The specific embodiment

Shown in Fig. 1-4, the described a kind of disposable biopsy forceps that has measurement function of this utility model embodiment, comprise operating handle 1 and binding clip device 2, described operating handle 1 is by stick 11, outer tube 12 and slip ring 13 constitute, wherein slip ring 13 is enclosed within on the stick 11 movably, be provided with steel wire Spin Control roller 14 near the right-hand member place on the outer wall of stick 11, the right-hand member of stick 11 connects binding clip device 2 by outer tube 12, binding clip device 2 comprises binding clip installing rack 21, be provided with upper grip head 22 and the lower pliers head 23 hinged near the right-hand member place on the binding clip installing rack 21 with binding clip installing rack 21, the left end of upper grip head 22 and lower pliers head 23 all is connected steel wire 24, and steel wire 24 passes outer tube 12 successively, the inside of stick 11 and steel wire Spin Control roller 14 also is connected with slip ring 13.

The lower surface of the upper surface of described upper grip head 22 and lower pliers head 23 is evenly distributed with five chequered with black and white graduation marks 3 respectively, and the width of graduation mark 3 is 1mm.

During concrete the use, steel wire Spin Control roller 14 is fixedlyed connected with steel wire 24, by the slip ring on the finger push stick 11 13, is transmitted motion on the binding clip by steel wire, make upper and lower binding clip open and close, reach the purpose of use, simultaneously, if the angle of binding clip and pathological tissues is bad, can stir steel wire Spin Control roller 14 on the stick 11 by finger, to be rotatablely moved by steel wire 24 is delivered on the binding clip, makes upper and lower binding clip rotation, adjusts to the angle that is beneficial to operation.In obtaining the process of pathological tissues, can measure the scope of diseased region simultaneously by the graduation mark on the upper and lower binding clip 3.Simple in structure, novel, has steel wire Spin Control roller on the operating handle, can control the rotation of binding clip, easy to operate, has the function of measuring the pathological changes size, when doing gastroscope or enteroscopy, can take off part chemical examination to pathological tissues, also can measure the size and the scope of pathological changes simultaneously.
