The utility model is able to ensure firm joints among parts and is easy to use. In addition, the utility model can also make the biopsy forceps pass through a bent way with a very small forceps hole, enhancing its practicability.
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 connection endoscopic biopsy pincers firm and easy to use between a kind of part are provided.
The technical scheme that realizes above-mentioned purpose is: a kind of endoscopic biopsy pincers, by two binding clips, the binding clip frame, left side connecting rod, right connecting rod, pull bar and outer tube are formed, left side connecting rod and right connecting rod are hinged with two binding clips respectively, a left side, the other end and the pull bar of right connecting rod are hinged, the binding clip frame is connected with outer tube, left side connecting rod is made up of the body of rod and two cylindrical bosses perpendicular to the body of rod, and cylindrical boss is fixed in the two ends of the body of rod, right 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 in an end of the body of rod, and the other end of the body of rod of right connecting rod has circular hole.
After adopting technique scheme, left side connecting rod is made up of perpendicular to the body of rod and the cylindrical boss of fixedlying connected with the body of rod with two the body of rod, right connecting rod is made up of perpendicular to the body of rod and the cylindrical boss of fixedlying connected with the body of rod with one 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 a left side, right connecting rod and binding clip hinged, an and left side, right connecting rod and pull bar hinged, because cylindrical boss is fixedlyed connected with the body of rod, thereby can not come off from connecting rod, it is firm to have guaranteed to be connected between connecting rod and binding clip and the pull bar, also avoided simultaneously the trouble of installing, 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 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, left side connecting rod 3 is made up of the body of rod and two cylindrical boss 3-1 perpendicular to the body of rod, and cylindrical boss 3-1 is fixed in the two ends of the body of rod, and make one with the body of rod, right connecting rod 3 ' form by the body of rod and cylindrical boss 3 '-1 perpendicular to the body of rod, and an end of the body of rod is fixed in cylindrical boss 3 '-1, and make one with the body of rod, right connecting rod 3 ' the other end of the body of rod have circular hole 8.Left side connecting rod 3 is hinged by a cylindrical boss 3-1 and binding clip 1, hinged by another cylindrical boss 3-1 and pull bar 4, the cylindrical boss 3-1 that is connected with pull bar 4 stretches in the suspension ring hole 7 of pull bar 4 heads, right connecting rod 3 ' hinged by cylindrical boss 3 '-1 on it and binding clip 1, the circular hole 8 of the other end is enclosed within on the cylindrical boss 3-1 of left connecting rod 3, realizes the hinged of right connecting rod 3 '-1 and pull bar 4 by 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, can connecting rod 3 ' the body of rod on perforate, will knock in this hole as an end of boss 3 '-1 of bearing pin, realize fixedlying connected of boss 3 '-1 and the body of rod.
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.
