Detailed Description

In order to make the objects, technical solutions and beneficial effects of the present invention more clearly apparent, the technical solutions of the present invention are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Referring to fig. 1 to 3, a wire introduction pliers includes: the pair of forceps heads 1 are respectively connected with a handle 2;

two steel wire guide pipes 3 are arranged and are respectively connected with different binding clip 1; wherein, two handles 2 detachable coaxial rotation connect, and when handles 2 were close to each other, two wire conduit 3's mouth of pipe kept away from each other.

In the traditional steel wire leading-in pliers, the pliers heads 1 are close to each other by holding the handles 2, and the pipe orifices of the two steel wire guide pipes 3 connected with the pliers heads are close to each other to complete butt joint; when needs are repeatedly docked, need both hands to move handle 2 (one hand is unfavorable for stably exerting oneself), steel wire pipe 3 is located between musculature and the bone this moment, needs great strength just to drive the pipe and keeps away from each other, and whole process keeps steadily avoiding bringing secondary damage for patient's wound, is difficult undoubtedly. When the forceps head 1 of the operation forceps approaches, the handle 2 is easy to hold, and the operation can be stably carried out by one hand; according to the steel wire leading-in pliers, the handles 2 are operated by one hand to be close to each other, so that the two steel wire guide pipes 3 can be relatively far away, after external force at the handles 2 is released, the steel wire guide pipes 3 can be close to each other under the tension of muscles, secondary butt joint is achieved, and meanwhile, the position of the whole steel wire guide pipe 3 is adjusted until the butt joint is successful; simple operation is convenient, utilizes the special structure of this device to realize that steel wire conduit 3 is stable each other and keeps away from, utilizes the tensile force drive steel wire conduit 3 that muscle was propped open by steel wire conduit 3 to be close to each other and accomplish the butt joint, and efficiency is high.

Furthermore, one end of each of the two steel wire guide pipes 3 is connected to the staggered binding clip 1 in a cross mode, and the other end of each of the two steel wire guide pipes 3 is butted after being bent.

When holding handle 2, binding clip 1 is close to each other, and No. 1 steel wire pipe and No. 2 steel wire pipes are temporarily established to two steel wire pipe 3, and No. 1 binding clip and No. 2 binding clips are temporarily established to two binding clip 1, and No. 1 handle and No. 2 handle are temporarily established to two handles 2, and No. 1 steel wire pipe is located the top of No. 1 binding clip and is connected with No. 2 binding clip fixed connection, and No. 2 steel wire pipe is located No. 2 binding clip tops and is connected with No. 1 binding clip. The No. 1 handle and the No. 2 handle are staggered and are rotationally connected at the staggered point; the No. 2 binding clip is connected with the No. 1 handle, and the No. 1 binding clip is connected with the No. 2 handle; with the middle of two binding clip 1 rule, when gripping handle 2, 1 binding clip and No. 2 binding clip are close to the department of ruling each other, and connect and then keep away from this line each other with steel wire pipe 3 on two binding clip 1, realize that handle 2 is close to each other then the effect that steel wire pipe 3 kept away from each other.

In addition, one ends of the two steel wire guide pipes 3, which are far away from the butt joint part, are respectively positioned at two sides of the binding clip 1. Namely, the distance exists between the axes of the two steel wire guide pipes 3 at the position where the two steel wire guide pipes are connected with the binding clip 1, so that the two steel wire guide pipes 3 are in a spiral bending state after being butted, and the steel wires are easy to be threaded.

Further, a matching groove 21 is formed in one handle 2, a fixing bolt 4 is arranged in the matching groove 21, and the other handle 2 is embedded into the matching groove 21 and is in clearance fit with the fixing bolt 4 through a matching hole; one end of the fixing bolt 4 far away from the handle 2 is connected with a fixing nut 5 through threads; the two sides of the two forceps heads 1 and the two sides of the two handles 2 are positioned on the same plane; and a gap is arranged between the paired forceps heads 1 and the paired handles 2 at the two sides of the fixing bolt 4.

When the gap exists, the butt ends of the steel wire guide pipes 3 are in butt joint, and when the two handles 2 approach each other and the gap disappears, the butt ends of the steel wire guide pipes 3 are separated. The steel wire leading-in pincers are put into the wound and also can be that the assembly of two handles 2 and binding clip 1 separately gets into, when the steel wire threading finishes and needs to take out the leading-in pincers of steel wire, can rotate fixation nut 5, separate two handles 2, take out respectively, and need not strut the soft tissue and take out, and the wound is littleer. The fixing nut 5 presses the two handles 2 together when rotated on the fixing bolt 4 so that the butt ends of the wire guides 3 are aligned with each other for subsequent butt joint. The width of the spacing slot determines the distance the wire guide ducts 3 can be distanced from each other.

Further, the outer sides of the two handles 2 are respectively connected with an operating ring 6. When a doctor operates, fingers are inserted into the operating ring 6, the control degree of the handle 2 can be improved, when the steel wire guide pipe 3 moves to be close to each other, the hand does not exert force at the moment, the hand contracts by means of soft tissues, or the exerted force is small, and the operating ring 6 can be prevented from falling off. One or more operation rings 6 may be provided.

Further, the method also comprises the following steps: a lock nut 7, the lower end of which is connected with at least one circle of friction strips 71; the outer wall of the fixed nut 5 is externally provided with threads, and the locking nut 7 is in threaded connection with the outer wall of the fixed nut 5; the friction bar 71 abuts against the handle 2.

Fixing nut 5 is rotatory to be in the same place two handles 2 laminating, and the butt joint end of steel wire pipe 3 aligns, and then rotatory fixing nut 5 presses friction strip 71 on handle 2 for handle 2 can't rotate and then realize two handle 2 fixed, can release handle 2 when wearing to restraint the steel wire and operate, and the convenience improves.

Further, the fixing bolt 4 includes: a support section 41 connected to the bottom of the fitting groove 21; a spiral section 42 coaxially connected with the support section 41 and threadedly connected with the fixing nut 5; wherein the diameter of the support section 41 is larger than the diameter of the spiral section 42.

When the fixing nut 5 is rotated to abut against the support section 41, it cannot be further rotated, and the effect of aligning the abutting ends of the wire guide tubes 3 is already achieved; the rotating fixing nut 5 is then rotated further to force the friction bar 71 to be fixed against the handle 2. The friction strip 71 may be made of rubber or other materials with high friction.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
