Abstract
The utility model relates to a bone surgery apparatus, in particular to a pair of butterfly-shaped bone piece locking forceps. The butterfly-shaped bone piece locking forceps comprise a pair of chelas, forceps handles and a hinged shaft, wherein the chelas are positioned at the top parts of the forceps handles. The special point is that the two chelas take the folding type; the lower end of the forceps handle is of the closed semi-arc handle; the two forceps handles are articulated with each other by the hinged shaft; the upper end surface of the hinged shaft is provided with a fixed drum with internal screw thread, and the fixing drum is longitudinally arranged; a locking sleeve with external screw thread is arranged in the fixed drum; and a guide sleeve is movably arranged in the locking sleeve. Therefore, the butterfly-shaped bone piece locking forceps have the advantages of accurate fixation, good stability, small trauma, high safety and quick fracture healing.
Description
(1) technical field
This utility model relates to a kind of bone surgery set, particularly a kind of butterfly type bone piece locking pliers.
(2) background technology
Along with the social productive forces development, people's lives rhythm is accelerated, the high-energy damage is more and more, often run into comminuted fracture in the clinical position, when steel plate is fixed in the tubular bone tension side, the fixing butterfly type bone piece of offside or front and back side also, this is will solve the bone piece to peel off less, keep bone piece blood fortune, the bone block reset, keep reset, fixed problem.In the clinical practice operation, as comminuted fracture between rotor, the lesser trochanter displacement fracture, long tubular bone fracture has butterfly type folded block, generally to use wire binding and fix, or use bone holder, the point-like reduction forceps is temporary fixed, after the boring, tensile screw is fixed, and uses the fixation with steel wire existence and is inserted in difficulty, time-consuming, easily injures vital tissues such as nervus vasculairs, operating time is long, hemorrhage many, and the steel wire of tying up that goes in ring easily causes nonunion, refracture; Bone holder fixedly the time soft tissue to peel off area big, can cause sequestrum, nonunion, internal fixation lost efficacy; The point-like reduction forceps is at 2 to be fixed, fixed poor stability, and when boring or tapping, butterfly type folded block shift in position causes and screws in the tensile screw difficulty.Be subjected to the more inspiration of stability principle of interlocking intramedullary nail sight and triangle,, develop butterfly type bone piece locking pliers through experiment repeatedly.
(3) summary of the invention
This utility model is in order to remedy the deficiencies in the prior art, and a kind of good stability, butterfly type bone piece locking pliers that wound is little are provided.
This utility model is achieved by the following technical solution:
A kind of butterfly type bone piece locking pliers, comprise a pair of chela, pincers handle and a jointed shaft, chela is positioned at the top of pincers handle, its special character is: two chelas are the formula of filling the span of a man's arms, space in two chelas leave reasonably, and described pincers handle lower end is closed semicircle camber handle, two pincers handles are hinged by jointed shaft, described jointed shaft upper surface is provided with one and vertically places tapped stationary magazine creel, and the externally threaded locking bushing of mounting strap in the stationary magazine creel is provided with active pilot sleeve in the locking bushing.
For the ease of placing electric drill, the pincers handle is bent downwards certain radian; To invagination 90 degree, in order to make butterfly type bone piece fixed screw holes at the center of two chelas, chela is upwards curved certain radian for the ease of the front end of fixing chela, and pincers handle inboard is provided with locking device; For the ease of operation, the tail end of locking bushing is provided with rotating handle, and the tail end of guide cylinder is provided with the guide cylinder handle.
This utility model has been realized under the situation of not peeling off soft tissue, butterfly type bone block reset, temporary fixed, aiming boring, tapping, fixing, once accurately finish, solved the fixation problem of butterfly type bone piece preferably, overcome fixation with steel wire or used bone holder, the fixed shortcoming of reduction forceps, fixing accurately, save time, laborsaving, wound is little, safe, effect that union of fracture is fast.
In a word, butterfly type bone piece locking pliers of the present utility model, it is fixing accurate to have, good stability, the advantage that wound is little, safe, union of fracture is fast.
(4) description of drawings
Below in conjunction with accompanying drawing this utility model is further described.
Fig. 1 is a front view of the present utility model.
Fig. 2 is a vertical view of the present utility model.
Among the figure, 1 chela, 2 guide cylinders, 3 locking bushings, 4 stationary magazine creels, 5 rotating handles, 6 guide cylinder handles, 7 handles, 8 jointed shafts, 9 pincers handles, 10 locking devices.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises a pair of chela 1, a pincers handle 9 and a jointed shaft 8, described chela 1 is positioned at the top of pincers handle 9, its design main points are: two chelas 1 are the formula of filling the span of a man's arms, space in two chelas 1 leave reasonably, pincers handle 9 lower ends are closed semicircle camber handle 7, two pincers handles 9 are hinged by jointed shaft 8, described jointed shaft 8 upper surfaces are provided with one and vertically place tapped stationary magazine creel 4, the externally threaded locking bushing 3 of mounting strap in the tapped stationary magazine creel 4, be provided with active pilot sleeve 2 in the locking bushing 3, pincers handle 9 is bent downwards certain radian, and chela 1 is upwards bent certain radian, and the front end of described chela 1 is to invagination 90 degree, described pincers handle 9 inboards are provided with locking device 10, described tail end with externally threaded locking bushing 3 is provided with rotating handle 5, and the tail end of described guide cylinder 2 is provided with guide cylinder handle 6.
Use butterfly type bone piece locking pliers of the present utility model, earlier hook the butterfly type bone piece of pulverizing with chela 1, fastening pincers handle 9, and with the locking device 10 of pincers handle 9 inboards, to clamp handle 9 fixes, to screw in the stationary magazine creel 4 of jointed shaft upper end with externally threaded locking bushing 3, make it arrive at the screw hole of butterfly type bone piece offside cortical bone or fixation steel plate, screw and be with externally threaded locking bushing 3, butterfly type bone piece is fixed on backbone or the steel plate by two chelas 1 of this butterfly type bone piece locking pliers and the front end of locking bushing 3, put into guide cylinder 2, guide cylinder 2 is extracted in electric drill boring out, measure length, after the tapping, screw in suitable screw, according to drill bit and the gaging hole device of choosing respective length with externally threaded locking bushing 3 length.Innovative point of the present utility model be to change 2 be fixed as 3 fixing, good stability, when resetting fixedly butterfly type bone piece, aiming boring, tapping are finished tensile screw and fixed, and this utility model adopts the split design, and be easy to operate in the art, the many usefulness of pincers.
