Abstract
The utility model relates to endoscope biopsy forceps and a connecting rod thereof. One end of the connecting rod presents a crisscross shape, two sides of the crisscross are provided with cylindrical connecting rod lug bosses, and the other end of the connecting rod is provided with a connecting rod hole. The endoscope biopsy forceps are provided with grip heads, connecting bars, a grip head bracket, the connecting rod and rivets; both ends of each connecting bar are provided with two round holes, the connecting rod lug bosses at the two sides of the connecting rod are respectively hinged with one ends of the two connecting bars, the connecting rod is movably connected with the grip head bracket, the two corresponding grip heads are movably connected with the grip head bracket through the rivets penetrating through grip head holes, and two cylindrical grip head lug bosses respectively pass through the round holes of the other ends of the two connecting bars to be hinged together. With the proposal adopted by the endoscope biopsy forceps and the connecting rod thereof, the crisscross at the upper end of the connecting rod has two symmetrical cylindrical connecting rod lug bosses which can be hinged completely with the connecting bars, and thus the two lug bosses play a role of two shaft pins. In addition, the connecting rod and the connecting bars are moved in a slideway of the grip head bracket to prevent the connecting bars from dropping from the connecting rod so that the connection is safe and reliable and the assembly and the manufacture are convenient.
Description
Technical field:
This utility model relates to a kind of endoscopic biopsy pincers and connecting rod thereof.
Background technology:
Endoscopic biopsy pincers of the prior art mainly are made up of binding clip, connecting rod, binding clip frame, connecting rod, rivet etc.The method of its connection is formed hinges by riveted joint usually.Cumbersome when preceding a kind of method is assembled, because the external diameter of whole biopsy forceps has only Φ 2, more difficult efficient is low really during riveted joint, and comes off easily.
Summary of the invention:
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of endoscopic biopsy pincers and connecting rod thereof are provided.
This utility model solves the problems of the technologies described above the technical scheme that is adopted: an end of the connecting rod of these endoscopic biopsy pincers is cross, and criss-cross both sides are columniform connecting rod boss, and the other end of connecting rod is provided with a connecting rod hole.
The diameter in connecting rod described in the utility model hole is 0.6 millimeter.
This utility model solves the problems of the technologies described above the technical scheme that is adopted and also comprises a kind of endoscopic biopsy pincers of connecting rod as mentioned above that have, it is characterized in that being provided with binding clip, connecting rod, binding clip frame, connecting rod and rivet, the connecting rod two ends are provided with two circular holes, the connecting rod boss on connecting rod both sides forms hinged with two connecting rod one ends respectively, connecting rod and binding clip frame flexibly connect, the binding clip of two correspondences is rotationally connected by rivet and the binding clip frame that passes the binding clip hole, and the circular hole that two columniform binding clip boss pass two connecting rod other ends respectively forms hinged.
After this utility model adopts such scheme, owing on the cross of connecting rod upper end two symmetric cylindrical connecting rod boss are arranged, can finish hingedly with connecting rod, two boss have played the effect of two pivot pins fully.And connecting rod and connecting rod all move in the slideway of binding clip frame, have guaranteed that connecting rod can not come off from connecting rod, make attachment security reliable, have also made things convenient for assembling and manufacturing simultaneously.

The specific embodiment:
Referring to Fig. 1～Fig. 6, one end of the connecting rod 2 of this utility model embodiment endoscopic biopsy pincers is cross, criss-cross both sides are columniform connecting rod boss 21, connecting rod boss 21 can be connected to form two hinges pairs with connecting rod 4, and the other end of connecting rod 2 has the connecting rod hole 22 of 0.6 millimeter of a Φ, can be used to the stay cord in fixed connecting rod 2 bourdon tubes.
The binding clip 1 of this utility model embodiment endoscopic biopsy pincers comprises body 11, and body 11 rear ends are provided with a binding clip boss 13, and body 11 front ends are groove shapes, and body 11 middle parts are provided with a binding clip hole 12.Connecting rod 4 two ends are provided with two circular holes 41, columniform binding clip boss 13 can play the effect of pivot pin, binding clip boss 13 is when circular hole 41 on the connecting rod 4 is connected, the well behaved hinges of i.e. formation activity, the athletic meeting of connecting rod 4 drives opening with closed of whole binding clip 1, and the front end of binding clip 1 is for the sampling end and be groove shapes, and aperture 14 is arranged above, can accurately grasp biopsy, thereby finish the biopsy sampling.
This utility model embodiment endoscopic biopsy pincers are provided with binding clip 1, connecting rod 2, binding clip frame 3, connecting rod 4 and rivet 5, binding clip 1, connecting rod 2, binding clip frame 3, connecting rod 4 and rivet 5 can adopt rustless steel or other to have the material of certain intensity to make, the connecting rod boss 21 on connecting rod 2 both sides is hinged with circular hole 41 formation of two connecting rod 4 one ends respectively, connecting rod 2 flexibly connects with binding clip frame 3, the binding clip 1 of two correspondences is rotationally connected with binding clip frame 3 by the rivet 5 that passes binding clip hole 12, the circular hole 41 that two binding clip boss 13 pass two connecting rod 4 other ends respectively forms hinged, and the grooves in the binding clip frame 3 play spacing and effect slideway.
This utility model embodiment also is provided with stay cord, and stay cord is connected with connecting rod 2.Stay cord can adopt steel wire rope or other that rope of certain fastness is arranged.Drivening rod 4 when twitching steel wire rope, the jaw that connecting rod 4 drives two binding clips 1 opens with closed, finishes the biopsy sampling.
