Abstract
The utility model relates to the technical field of medical instruments, in particular to a pair of novel orthopedics bone holding forceps, namely, a pair of split-type four-claw bone holding forceps. The pair of split-type four-claw bone holding forceps mainly comprises a static forcep handle, a movable forcep handle, split-type claws, and a rotary pressurizing screw, wherein, the rotary pressurizing screw is screwed at the tail of the static forcep handle; arc-shaped claws are arranged at the front end of the static forcep handle, and a guiding groove is formed in the middle thereof; the static forcep handle and the movable forcep handle are in sliding fit with each other through the guiding groove and guiding screws; connecting shafts combined with the split-type claws are arranged at the front end of the movable forcep handle; the tail end of the movable forcep handle is connected with the rotary pressurizing screw; a limit screw used for preventing the rotary pressurizing screw from falling out is arranged on the movable forcep handle; the arc-shaped claws of each split-type claw adopt a pair of eudipleural claws; a lantern ring is arranged at the back part of each the each arc-shaped claw; the internal diameter of the lantern ring is slightly larger than the external diameter of a corresponding connecting shaft on the movable forcep handle, so that, the arc-shaped claw can be connected with the connecting shaft of the movable forcep handle through the lantern ring; two guiding screws are arranged on the movable forcep handle in positions corresponding to the guide groove of the static forcep handle; and the movable forcep handle slides on the static forcep handle by matching the two guiding screws mounted on the movable forcep handle with the guide groove.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of novel orthopaedics bone holding forceps.
Background technology
When carrying out the long bone shaft fracture reattachment surgery, all need fracture end to be clamped with bone holding forceps, place steel plate then or intramedullary pin is fixed, clinical used three-pawl type bone holding forceps are because be the bikini contact at present, when especially only using the interim clamping of three-jaw bone holding forceps carrying out intramedullary pin to fix, be easy to generate looseningly, make reduction of the fracture failure.In addition, when carrying out that intramedullary pin is fixed and only need be when fracture to be made little otch and is resetted, the three-pawl type bone holding forceps tend to hindered by skin and be difficult to insert because pawl.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, provides a kind of easy and simple to handle, the reliable bone holding forceps of clamping.
The technical solution of the utility model is achieved in that split type four paws bone holding forceps, mainly including quiet pincers handle, moving pincers handle, split pawl and spinning forms in the rotation pressurization screw rod of quiet pincers handle tail, quiet pincers handle front end is provided with the arc pawl, the middle part has gathering sill, and quiet pincers handle cooperates slip with moving pincers handle by gathering sill and guider screw; Moving pincers handle front end is provided with and the bonded connecting axle of split pawl, and end links to each other with rotation pressurization screw rod, and moving pincers handle is provided with the stop screw of preventing that spline pressurization screw rod comes off.The arc pawl of split pawl is a pair of symmetrical pawl, and the rear portion is provided with the collar, and collar internal diameter is slightly larger than corresponding connecting axle external diameter on the moving pincers handle, so that be connected by the connecting axle of the collar with moving pincers handle.Moving pincers handle is provided with two pieces of guider screws with the gathering sill corresponding position of quiet pincers handle, and moving pincers handle is engaged on the quiet pincers handle and slides by being installed on moving two pieces of guider screws on the handle and the gathering sill of clamping.
After adopting technique scheme, when needs are fractured when keeping the especially little otch that resets and resetting, can remove down split pawl, can conveniently the quiet pincers handle of bone holding forceps be inserted control skeleton apart from otch than far-end, this process can avoid pawling of Contiuum type to be hindered the problem that is difficult to insert by skin; After bone holding forceps are put the position well, install the split pawl, it is stressed that when screwing screw rod clamping fracture because fracture two ends are two relative point symmetries, improved clamping stability; Simultaneously, because the split pawl is connected for ring, axle with moving pincers handle, so the feasible rotary moveable of split pawl is still closely clamping when there is the thickness gap at the fracture two ends.
Description of drawings
Fig. 1 is the structure chart of the split type four paws bone holding forceps of this utility model.
The specific embodiment
Split type four paws bone holding forceps mainly are made up of in the rotation pressurization screw rod 4 of quiet pincers handle 1 afterbody quiet pincers handle 1 moving pincers handle 2 split pawls 3 and spinning, form a pair of symmetrical arc pawl 5 at quiet pincers handle 1 front end, have gathering sill 6 on the quiet pincers handle 1, quiet pincers handle 1 cooperates slip by two pieces of guider screws 10 that are installed on the moving pincers handle 2 with gathering sill 6 with moving pincers handle 2, moving pincers handle 2 front ends are provided with connecting axle 7, split pawl 3 is connected with connecting axle 7 by the collar 8, fracture when keeping the especially little otch that resets and resetting when needs like this, can remove split pawl 3 down, be convenient to the arc pawl 5 of quiet pincers handle 1 front end is inserted.Split pawl 3 is provided with the arc pawl 9 of a pair of and quiet pincers handle 1 front end arc pawl 5 same width, and the fracture two ends are 2 stressed relatively rock-steady structures when realizing the clamping fracture like this.Because split pawl 3 is connected for ring, axle with moving pincers handle 2, so split pawl 3 feasible rotary moveables are still closely clamping when there is the thickness gap at the fracture two ends simultaneously.Moving pincers handle 2 is terminal to be processed into flexible connection with rotation pressurization screw rod 4, and moving pincers handle 2 is provided with and changes pressurization screw rod 4 and put the stop screw 11 that comes off, and can prevent that rotation pressurization screw rod 4 from deviating from moving pincers handle 2 ends.
