Abstract
The utility model discloses a Y-shaped elastic external fixer. A fixed block and an attachment stand can both fix steel needles and are both connected with a supporting body via cardan joints. The lower part of the attachment stand is provided with two arms. In the treatment to pilon fracture, the upper steel needles are fixed to the front inner side of the tibia; a forearm fixes the steel needles to the foot scaphoid bone through a slide block; a back arm fixes the steel needles to the calcaneus through the slide block. The utility model has advantages as follows: firstly, the triangle frame structure of the external fixer is favorable for stable fracture ends in early stage static fixation; secondly, after the corresponding fixing screws are loosened, the ankle joint can do early stage functional exercise under the spring stress function of a spring, favorable for the joint function recovery, preventing further fracture movement.
Description
(1) technical field: this utility model relates to medical apparatus and instruments, especially for the external fixation device of the reduction of the fracture, especially has the external immobilizer for fracture restitution tool of function of joint.
(2) background technology: a kind of good fracture fixation mode should possess 3 points, that is: fracture end is fixing firm, and less function replacement can make bone stump obtain physiology and use.And under the same conditions, early functional exercise has significance in the fractures process, is the important measures that accelerating union of bone fracture improves healing quality, by increasing blood circulation, can prevent joint accretion, amyotrophy, the generation of complication such as osteoporosis.
In the traditional medicine, curing the treatment of fractures method is plaster fixation, traction or internal fixation.Its drawback is to bring many miseries to the patient, and is difficult for healing and early stage restorative functional activity.This situation for a change, the patent of a kind of " one-sided multi-functional external fixation treatment of joint disease device " provides new therapeutic device, comprise fixedly fixture block, universal joint, oval support body, between oval support body and strap, be provided with balland socket joint, stretch the joint arrangement of bending the joint.Its advantage is that fixed effect is better, scalable, rotation, thus help treatment, but it still exists the defective of elastic performance and less stable, and have stress shielding, can't make the stress stimulation that obtains discontinuity between fracture site; Moreover after fixing, joint part can't carry out early functional exercise.Especially the fracture of the pilon in the medical science (being that distal tibial involves articular surface fracture) is a kind of more special fracture, and the problem when treatment is just more outstanding.
(3) summary of the invention: the purpose of this utility model is to provide a kind of fracture end fixing firm, scalable, rotation, and elasticity is fracture external fixator preferably.
The purpose of this utility model realizes by following scheme: " Y " shape elastic force external fixator, comprise fixed block, fixed mount and support body, fixed block, fixed mount be fixing draw point all, and all adopts universal joint to be connected with support body, and be characterized in: the bottom of fixed mount is provided with two arms that stretch out.
This utility model can be done following further extension: two arm angles can be regulated arbitrarily; Universal joint comprises the spheroid that respectively carries connector, and buckle cover and pallet are provided with the restriction button on the body wall under the pallet; Support body is made up of the body cavity and the support body core that respectively carry connector, is provided with spring between a body cavity and the support body core, and the body wall of chamber groove is provided with fixing button.
This utility model is suitable for treatment pilon fracture, during use, its top draw point is fixed in before the tibia inboard, and two fixed arms are extended in the bottom, and forearm is fixed in navicular bone by draw point, and postbrachium is by on the fixing dried calcaneus of draw point.
The utlity model has following advantage: 1, external fixer is the triangle-frame structure, during early stage static fixation, helps the stable of fracture end; 2, after pine removes corresponding fixed screw, can make ankle joint under spring bullet stress, carry out early functional exercise, help the recovery of function of joint, prevent fracture redisplacement;
3, make economy, be easy to promote.
(4) description of drawings: Fig. 1 is this utility model structural representation; Fig. 2 is this utility model part-structure sketch map.
In the accompanying drawing: 1 is fixed block, and 2 is support body, and 3 is fixed mount, and 4 is fixture block, 5 is the duct, and 6 is screw, and 7 is spheroid, 8 is the buckle cover, and 9 is snap seats, and 10 is pallet, 11 is eccentric shaft, and 12 are a body cavity, and 13 is the support body core, 14 is the chamber groove, and 15 is core body, and 16 is spring, 17 is stand, and 18 is boom, and 19 for tightening up slide block.
(5) specific embodiment: utility model is further described below in conjunction with embodiment:
Embodiment 1: as shown in Figure 1, " V " shape elastic force external fixator, fixed block (1) is by two half elliptic fixture blocks (4), connect to form by screw (6), wherein a fixture block is L-shaped, two fixture block inboards respectively have corresponding half slot, and two half slots form the duct (5) of wearing draw point, fixedly draw point.In the time of fixedly, earlier draw point is fixed in patient relevant position (inboard before the tibia), then draw point is penetrated the duct, tighten screw, thereby make fixture block clamp draw point.
Support body (2) (not marking among the figure) is by being divided into a body cavity (12) and support body core (a 13) two large divisions, and the chamber groove (14) of a body cavity bottom is with the core body (15) on support body core top, connect by spring (16), and the chamber cell wall is provided with screw, is used to tighten up chamber groove and core body.Support body core cross section can be made as semicircle shape, and the chamber slot cross-section is corresponding with it to coincide.When this utility model uses, unclamp screw, a body cavity and support body core are kept in touch under spring action.
Fixed mount (3) is made up of stand (17) and boom (18), and boom is fixed on the stand by screw, and boom can be established forearm and postbrachium, and two arm angles can be regulated arbitrarily, is equipped with slide block (19) on two arms, and slide block can be fixed on the boom by screw; Slide block is provided with draw point duct and corresponding hold-down screw, penetrates draw point, by tightening screw, draw point can be fastened at slide block.During use, fixing brachiocubital steel nail is fixed in navicular bone, and the draw point of postbrachium is fixed on the calcaneus.
As shown in Figure 2, fixed block, fixed mount all adopts power to be connected to joint with support body, fixed block is connected with a body cavity, fixed mount is connected with the support body core, universal joint comprises spheroid (7), buckle cover (8), snap seats (9), pallet (10) and restriction button, make by stainless material, when carrying out the universal joint making and installing, spheroid is fixed in fixed block bottom (fixed mount top), be with a buckle cover on the spheroid, snap seats is located at a body cavity top (support body core bottom), earlier pallet is put into snap seats, be inserted in snap seats by the buckle cover again, the revotating card retaining ring, thereby fastening buckle cover and snap seats, the restriction button can be made up of eccentric shaft (11), is arranged in the body cavity (support body core) of pallet below (top), when unclamping eccentric shaft, pallet is away from spheroid, but the spheroid any direction rotates; When tightening eccentric shaft, pallet is close to spheroid, and spheroid does not rotate, thus the fixing angle position between spheroid and the buckle cover of scalable.
This utility model is made one with fixed block (fixed mount) and spheroid, and snap seats is made one with a body cavity top (support body core bottom).
