Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically, relates to a kind of endoscopic biopsy pincers.Be mainly used in living tissue pick test under the endoscope, be one of indispensable apparatus of Endoscopy Room.
Background technology
Endoscopic biopsy pincers of the prior art mainly are made up of binding clip, binding clip frame, rivet, connecting rod etc., its method of attachment is that independent connecting rod is hinged by rivet and binding clip and pull bar, the shortcoming that adopts this method is that rivet easily comes off, cause connecting rod easily to get loose, and in assembling time, is also pretty troublesome.In addition, conventional pull bar is a push-and-pull rod, and biopsy forceps is difficult to pass through when crossing very little biopsy channel hole bend.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of improved endoscopic biopsy pincers are provided, and it is firm that it not only can guarantee to connect between its part, and use, easy for installation.
The technical scheme that realizes above-mentioned purpose is: a kind of improved endoscopic biopsy pincers, form by two binding clips, binding clip frame, left connecting rod, right connecting rod, pull bar and outer tube, left side connecting rod and right connecting rod are hinged with two binding clips respectively, the other end and the pull bar of left and right connecting rod are hinged, the binding clip frame is connected with outer tube, be fixed with the bearing pin that is used for left and right sides rod hinge connection on the binding clip, left side connecting rod is made up of the body of rod and the cylindrical boss perpendicular to the body of rod, and cylindrical boss is fixed on an end of the body of rod, the other end of left side connecting rod has hinge hole, and the two ends of right connecting rod all have hinge hole.
After adopting technique scheme, be fixed with the bearing pin that is used for left and right sides rod hinge connection on the binding clip, left side connecting rod is made up of the body of rod and the cylindrical boss perpendicular to the body of rod, cylindrical boss perpendicular to the body of rod just is equivalent to bearing pin, it can replace rivet and help realize the hinged of left and right connecting rod and pull bar, the hinged of left and right connecting rod and binding clip then can be realized by fixed bearing pin on the binding clip, this bearing pin is fixedlyed connected with binding clip, can not come off, guarantee that connecting rod is firm with being connected of binding clip from binding clip.Because cylindrical boss is fixedlyed connected with the body of rod, thereby can not come off from connecting rod again, it is firm to have guaranteed to be connected between connecting rod and the pull bar, and the while has also been avoided the trouble of installation, and is very convenient to use.
The further purpose of this utility model is: make the endoscopic biopsy pincers can pass through very little biopsy channel hole bend.
The further technical scheme of this utility model is: pull bar is formed by the individual wire bending, and its shape is as suspension ring; The afterbody of pull bar is set with fixed cover, and fixed cover can be a bourdon tube, also can be plastic tube.
Pull bar after the employing technique scheme can be crooked, and resilience is arranged, and cooperates fixed cover just can reach again and make biopsy forceps cross the very purpose of inner curve, strengthened the function of biopsy forceps.

The specific embodiment
Below in conjunction with drawings and Examples this utility model is described in further detail.
Shown in Fig. 1～8, a kind of improved endoscopic biopsy pincers, by two binding clips 1, binding clip frame 2, left side connecting rod 3, right connecting rod 3 ', pull bar 4 and outer tube 6 are formed, left side connecting rod 3 and right connecting rod 3 ' hinged with two binding clips 1 respectively, a left side, right connecting rod 3,3 ' the other end and pull bar 4 hinged, binding clip frame 2 is connected with outer tube 6, be fixed with on the binding clip 1 and be used for and left and right sides connecting rod 3,3 ' hinged bearing pin, left side connecting rod 3 is made up of the body of rod and the cylindrical boss 3-1 perpendicular to the body of rod, and cylindrical boss 3-1 is fixed on an end of the body of rod, and make one with the body of rod, this cylindrical boss 3-1 stretches in the suspension ring hole 7 of pull bar 4 heads, the other end of left side connecting rod 3 has hinge hole 8, this hinge hole 8 is enclosed within on the bearing pin 1-1 of left binding clip 1, realization is hinged with binding clip 1, right connecting rod 3 ' two ends all have hinge hole 9, the hinge hole 9 of one end is enclosed within on the bearing pin 1-1 of right binding clip 1, realization is hinged with binding clip 1, the hinge hole 9 of the other end is enclosed within on the cylindrical boss 3-1 of left connecting rod 3, realizes hinged with pull bar 4 by this cylindrical boss 3-1.
Also can perforate on the body of rod of connecting rod 3, will knock in this hole as the end of the boss 3-1 of bearing pin, realize fixedlying connected of boss 3-1 and the body of rod.Equally, the bearing pin 1-1 on the binding clip 1 can make one with binding clip 1, also can perforate on binding clip 1, bearing pin 1-1 is struck as in this hole, and realize fixedlying connected of bearing pin 1-1 and binding clip 1.
As shown in Figure 6, pull bar 4 is formed by the individual wire bending, and its shape is as suspension ring.The afterbody of pull bar 4 is set with fixed cover 5, and fixed cover 5 can be a bourdon tube, also can be plastic tube.The pull bar 4 of this structure is flexible, and has resilience, cooperates fixed cover 5 just can realize making biopsy forceps to pass through the very purpose of inner curve again.
Shown in Fig. 3,4,5, outer tube 6 is formed by the flat spring coiling.Biopsy forceps outer tube of the prior art is made spring-like by the circle filament winding, and the spring that maybe will justify filament winding system is again through handling (as the spring peripheral milling is flat).The weak point of the method is that the spring of circle filament winding system takes up room greatly, and such as the bourdon tube of same internal diameter and hardness, the spring of circle filament winding system is bigger than the spring external diameter of flat filament coiling.And in this utility model by the outer tube of flat spring coiling under the situation of same diameter of bore, external diameter is less relatively, easily by narrow and small endoscope's biopsy channel hole.
