Abstract
A pair of multifunctional fracture reduction oriented pliers is formed by a pair of embracing pliers, equally-dividing connecting arms, a sliding ring, a central oriented sleeve, a quick pressing barrel and an inner sleeve in a combined mode. The pair of the embracing pliers is formed by two mutually crossed plier bodies through a rotary shaft, the front end of each plier body is an arc-shaped embracing plier jaw, and the middle of each plier body is provided with a sliding fastener. The equally-dividing connecting arms are two equilong metal rods which are connected with the equilong portions of the two plier bodies of the embracing pliers respectively through rotary shafts, and the other end of each metal rod is connected with the sliding ring through a rotary shaft. One end of the central oriented sleeve is connected with the rotary shaft of the embracing pliers, and the other end of the central oriented sleeve is sleeved into the sliding ring. The quick pressing barrel is formed in the mode that two inverted L-shaped buckling teeth are connected with the inner sleeve through rotary shafts, the inner diameter of the inner sleeve is a little larger than the outer diameter of the central oriented sleeve, and the inverted L-shaped buckling teeth are quickly fixed to the quick pressing barrel through U-shaped springs. The pair of the multifunctional fracture reduction oriented pliers is used for positioning of an external fixator bone drilling needle; simple oblique fracture reduction positioning and drilling; bone fracture plate positioning and drilling; bone fracture plate auxiliary fracture reduction positioning and drilling.
Description
Technical field
This utility model relates to a kind of orthopedic medical device field, and is a kind of for pilot hole specifically, the medical apparatus and instruments of the auxiliary reduction of the fracture.
Background technology
In the bone surgery, often Kirschner wire or osseous pin need be fixed fracture at present, Kirschner wire or osseous pin pass its hold maximum of skeleton center, and be fixing the most firm.But because long diaphysis is cylindrical substantially, smooth surface, Kirschner wire slides in bone surface easily, depart from position in advance, fixing failure occurs, particularly tend to the development of Wicresoft's direction along with bone surgery, often need closed inserting needle, can not see the skeleton overall picture clearly, the obstruction of skeleton surrounding skin, fascia, muscle in addition, operating difficulty is big, being prone to locking pin slides, borehole throw appears, boring repeatedly, even iatrogenic fracture appears.Reduction of the fracture internal fixation is more and more to use the Mippo technology, because little otch can not be seen the overall picture of skeleton and blade plate, is prone to skeleton and becomes the angle with blade plate, can't hold-down screw.
Summary of the invention
The purpose of this utility model provides a kind of Kirschner wire, osseous pin, bit bore of quick and precisely leading, fixation bone fracture plate and key keeping parallelism, the multi-functional medical apparatus and instruments of the auxiliary reduction of the fracture.
For achieving the above object, this utility model is taked following design:
A kind of multi-functional reduction of the fracture guiding pincers, by encircle pincers, five equilibrium linking arm, slip ring, centre pilot sleeve, add pressure cylinder fast, inner sleeve constitutes, wherein encircle pincers and be made up of by rotating shaft two cross one another calipers, its front end is that arc is encircled jaw, is provided with slide fastener in the middle of the caliper; Described five equilibrium linking arm by two isometric Metallic rod encircle pincers two strong points such as caliper connected by rotating shaft, the other end of two Metallic rod is connected by rotating shaft with slip ring; Described centre pilot sleeve one end with encircle pincers rotating shaft be connected, the other end is inserted in the slip ring; The described pressure cylinder that adds fast is connected with the sleeve that an internal diameter is slightly larger than the centre pilot sleeve outer diameter by rotating shaft by two inverted "L" shaped buckle teeth, the inverted "L" shaped buckle teeth by " U " shape spring with add pressure cylinder fast and fix.
Described five equilibrium linking arm by two isometric Metallic rod encircle pincers two strong points such as caliper connected by rotating shaft, the other end of two Metallic rod is connected by rotating shaft with slip ring, utilize the angular bisector mathematical principle, inner sleeve is under the drive of slip ring, inner sleeve under any state all on the jaw bisector, key cross section be circular substantially, and jaw is tangential on the backbone, so can pass through key center when holing.
Described jaw and caliper are " Z " shape design makes jaw and inner sleeve at grade, by encircle pincers, inner sleeve to blade plate, that the backbone carries out cluster is temporary fixed.
Described inner sleeve periphery is flat thread, and two inverted "L" shaped buckle teeth that add pressure cylinder fast buckle into and are difficult for slippage in the flat thread.
Described multi-functional reduction of the fracture guiding pincers, jaw is inboard for the design of annular knurl stricture of vagina, is conducive to control skeleton.
Described inner sleeve head end is hollow cone shape, and is supporting with blade plate nail hole, and the inner sleeve head end inserts blade plate nail hole, makes blade plate stressed evenly, and can carry out stress conduction and controlled pressurization constant, that continue to blade plate, skeleton, reaches cluster and fixes.
Described inner sleeve head end is hollow cone shape, and its periphery has the screw thread that matches with the locked pressurized bone plate lock hole, can be connected with the blade plate lock hole, can directly hole after fixing.
In order to be fit to different big or small Kirschner wires, osseous pin, bit bore guiding, described inner sleeve inner hollow diameter is divided into different size specifications.
For the fracture location that can be fit to different sizes resets, multi-functional reduction of the fracture guiding pincers are divided into large, medium and small plurality of specifications.
This utility model advantage: these multi-functional reduction of the fracture guiding pincers, by encircle pincers, inner sleeve to fracture carry out cluster reset temporarily, fixing, undertaken Kirschner wire, osseous pin, bit bore guiding by centre pilot sleeve, inner sleeve again, its five equilibrium linking arm can both make boring by key center under any state, reaches the optimal fixation state.
These multi-functional reduction of the fracture guiding pincers, slide fastener designs in the middle of caliper, does not hinder electric drill boring.
This multifunctional guide boring reduction of the fracture pincers, the inner sleeve periphery adds pressure cylinder fast for flat thread designs by rotating, and blade plate, skeleton are carried out stress conduction and controlled pressurization constant, that continue, fracture end is finely tuned carry out the reduction of the fracture.
These multi-functional reduction of the fracture guiding pincers, described inner sleeve head end is hollow cone shape, by temporary fixed to blade plate to blade plate nail hole, blade plate is with key parallel and be tangential on key periphery, avoid blade plate become with skeleton angle, blade plate nail hole not key central in addition outside the backbone, can't hold-down screw.
These multi-functional reduction of the fracture guiding pincers, each fixes two multi-functional reduction of the fracture guiding pincers in the fracture proximal-distal, blade plate is fixed with key, because multi-functional reduction of the fracture guiding pincers can be to the backbone, it is temporary fixed that blade plate carries out cluster, blade plate is with key parallel and be tangential on key periphery, 4 fixing, key shape is consistent with blade plate, can can finish the fracture angulation displacement not cutting fracture end, lateral displacement, by traction, rotation is suffered from limb and is corrected fracture cripetura displacement, rotation displacement, last each slide fastener of fastening and inner sleeve, the reduction of the fracture is temporary fixed to be finished, the hold-down screw of can directly holing, reduce operation wound greatly, simple, reduce intraoperative hemorrhage and operating time, realize Minimally Invasive Surgery.
