Abstract
The invention relates to arc resetting needle forceps. The arc resetting needle forceps comprise a fixed forcep head, a movable forcep head, a sleeve, a front handle and a back handle. The front end of the back handle and the front end of the front handle are connected with a forcep rod base; a pull rod base is arranged in the forcep rod base; the two ends of the pull rod base are sleeved with a spring base and a combined cap; the pull rod base is sleeved with a spring; the back handle is connected with one end of the pull rod base; the other end of the pull rod base is connected with the tail end of a pull rod; the front end of the pull rod is in shaft connection with a second connecting sheet; the second connecting sheet is in shaft connection with the movable forcep head; the movable forcep head is in shaft connection with the sleeve; the fixed forcep head is a concave arc face matched with a convex arc face; a set of small teeth are arranged on the concave arc face; and arcs of the small teeth are the same as a suture needle in diameter. The arc resetting needle forceps have the beneficial effects that the structure is simple and reliable; the resetting function is achieved; rapid suturing is achieved; when the needle is clamped, under the mutual effect of the large arc and the small arc, the forcep heads will reset to the suture positions enabling a needle head to be upward when any position of the needle is clamped by the forcep heads, and therefore working loads of a doctor are accordingly reduced. Thread clamping is carried out through the large arc, and the suture thread cannot be damaged.
Description
Technical field
The invention belongs to medical instruments field, mainly a kind of circular arc reset needle forceps.
Background technology
The existing needle forceps complex structure operated under peritoneoscope, it is undertaken holding pin and clamp use by the tooth in the black steel disc on binding clip.When holding pin with needle forceps in practice, pliers head clip just can not on stitching position on this position at any position pin of pin, so doctor will operate pliers and makes pliers head be clipped in the suture site of pin in operation, which adds the working strength of doctor and the technology of doctor, old product can not depth be sewed up, and can only laterally sew up.Destroy the integrity of pin and line because binding clip head is that its hardness of tooth of Wu Gang processing is very high holding the conference of exerting oneself of doctor in pin and clamp process in addition, that will interrupt at sewing process through control bad when organizing or line by pin in sewing process.The medical treatment cost of patient will be increased like this.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art existence, and a kind of circular arc reset needle forceps is provided.
The object of the invention is to have come by following technical solution.This circular arc reset needle forceps, comprise and determine binding clip, dynamic binding clip, sleeve pipe, pull end and rear handle, rear handle is connected with claw beam seat by the first brace with the front end of pull end, draw-bar seat is provided with in claw beam seat, two ends of draw-bar seat be set with spring base with and emit, spring housing to be contained on draw-bar seat and be arranged on spring base and and between emitting; Rear handle is connected with one end of draw-bar seat by the first brace, the other end of draw-bar seat is connected with the end thread of pull bar, pull bar is set with sleeve pipe, the front end of pull bar is coupling by the second rotating shaft and the second brace, second brace is coupling by the first rotating shaft and dynamic binding clip, meanwhile, dynamic binding clip is coupling by the front end of bearing pin and sleeve pipe; The mating surface of described dynamic binding clip is convex arc surface, and determining binding clip is the concaved circular cambered surface coordinated with convex arc surface, concaved circular cambered surface has the one group of little tooth coordinated with sewing needle; Convex arc surface is the same with the radian of stitching with the circular arc of concaved circular cambered surface, and the circular arc of little tooth is the same with the diameter of sewing needle.
Described rear handle is provided with button and pintle hook lock, and button and pintle hook lock are coupling by connecting rod, and pull end is provided with tooth bar, and pintle hook lock and tooth bar are connected in snap-fit engagement in the locked condition.
Described claw beam seat is provided with cleaning joint, the intracavity inter-connection of cleaning joint and sleeve pipe.
Beneficial effect of the present invention is: the present invention is simple and reliable for structure, there is reset function, by the centralized positioning of head two circular arcs, reach rapid suture, when pressing from both sides pin due to large small arc-shaped interact under be exactly that pliers head clip all can reset to syringe needle stitching position upward at any position of pin, thus reduce the workload of doctor.Because clamp is undertaken by orthodrome, so can not destroy sutural.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed introduction is done to the present invention:
As shown in the figure, this circular arc reset needle forceps, comprise and determine binding clip 1, dynamic binding clip 2, sleeve pipe 4, pull end 7 and rear handle 12, rear handle 12 is connected with claw beam seat 6 by the first brace 9 with the front end of pull end 7, draw-bar seat 8 is provided with in claw beam seat 6, two ends of draw-bar seat 8 be set with spring base 17 with and emit 15, spring 16 to be sleeved on draw-bar seat 8 and be arranged on spring base 17 and and emit between 15; Rear handle 12 is connected with one end of draw-bar seat 8 by the first brace 9, the other end of draw-bar seat 8 is connected with the end thread of pull bar 3, pull bar 3 is set with sleeve pipe 4, the front end of pull bar 3 is coupling by the second rotating shaft 22 and the second brace 21, second brace 21 is coupling with dynamic binding clip 2 by the first rotating shaft 20, meanwhile, dynamic binding clip 2 is coupling by the front end of bearing pin 19 with sleeve pipe 4; The mating surface of described dynamic binding clip 2 is convex arc surface 2-1, and determining binding clip 1 is the concaved circular cambered surface 1-1 coordinated with convex arc surface 2-1, concaved circular cambered surface 1-1 has the one group little tooth 18 coordinated with sewing needle.Convex arc surface 2-1 is the same with the radian of stitching with the circular arc of concaved circular cambered surface 1-1, and the circular arc of little tooth 18 is the same with the diameter of sewing needle.Described rear handle 12 is provided with button 10 and pintle hook lock 13, button 10 and pintle hook lock 13 are coupling by connecting rod 11, pull end 7 are provided with tooth bar 14, and pintle hook lock 13 and tooth bar 14 are connected in snap-fit engagement in the locked condition.Described claw beam seat 6 is provided with cleaning joint 5, cleaning joint 5 and the intracavity inter-connection of sleeve pipe 4, can rinse by water receiving.
Work process: sewing needle is put into and determines on the little tooth 18 of binding clip 1, after connecing pressure, handle 12 and pull end 7, first brace 9 pull pull bar 3 to left movement, and drive dynamic binding clip 2 to press down, binding clip 1 is closed with determining; When opening, pressing button 10, pintle hook lock 13 and tooth bar 14 depart from, and drive pull bar 3 to move right, thus binding clip 2 is opened.The hardness that the hardness ratio sewing needle of needle section material is held in circular arc reset is little, therefore can not destroy the shape of sewing needle.Head design adopts large small arc-shaped combine, convex arc surface 2-1 is the same with the radian of stitching with the orthodrome of concaved circular cambered surface 1-1, and the small arc-shaped of little tooth 18 is the same with the diameter of sewing needle.By the centralized positioning of head two circular arcs, reach rapid suture, pliers when pressing from both sides pin due to large small arc-shaped interact under be exactly pliers head clip all can reset to syringe needle stitching position upward at any position of pin, thus reduce the workload of doctor.Because clamp is undertaken by orthodrome, so can not destroy sutural.
The present invention is not limited to above-mentioned embodiment, no matter do any change, every employing structural design provided by the present invention on its shape or material are formed, is all one distortion of the present invention, all should thinks within scope.
