Description
Technical field
The invention belongs to technical field of medical instruments, particularly relate to a kind of carry out calcaneus fractures with
Reduction fixed support.
Background technology
External fixed support for bone may be used for the treatment of the most common fracture, it is also possible to is used for correcting certain
A little bone malformation, are the important utensils of one of orthopaedics.Any exter-nal fixer all includes fixing pin, fixes
Pin fixture and three kinds of basic elements of character of connecting rod, when for fractures, its operational approach is typically
After the reduction of the fracture, select thread a needle position and the fixing pin of angle insertion, then fixture, connecting rod are installed
Deng, select thread a needle position and angle time, it should preferentially meet claimed below: fixing pin as far as possible with
Key vertical；Fixing pin avoids damage to neural blood vessel as far as possible, the most multidirectional threads a needle, and strengthens antitorque
Turn performance.But it is it is true that conventional external fixator is higher to angle, the status requirement of fixing pin, outer solid
Determine frame structures shape needling position own and the bounds of lower pin angle, when deviation occurs, just
Can cause connecting rod installation difficulty, after easily occurring installing, the situation such as fracture end displacement, needs again to insert
Enter fixing pin and the problems such as connecting rod are installed again.
The Chinese utility model patent of Application No. 200920085010.4 discloses a kind of calcaneus multiple
Position external fixer, including the screw rod of the positive and negative interior female thread of two ends band, is arranged with at the two ends of screw rod
Universal joint, universal joint is made up of ball screw, screw base, hold-down column, housing screw, bulb
Screw correspondence screw rod is provided with screw thread and screws in screw rod, and the bulb of ball screw is positioned at screw base, ball
It is the face cooperated that head is provided with hold-down column, spherical surface and compression face, residence, and hold-down column passes through screw
Housing screw on seat is fixed.Although so calcaneus replacement and fixation support facilitates fixing pin direction
The regulation of angle, but there are the following problems in meeting:
1. universal joint is attached by screw rod, and in the treatment of fracture of calcaneus, it is common that respectively
Tibia, nut bone and calcaneus are fixed pin location respectively and also and then form a frame structure, because of
This, this to carry out calcaneus fractures by a screw rod very unrealistic；Want to be formed 3 points simultaneously
The frame structure of location, it is necessary to using the connecting rod of at least three, this will make whole operation use
Part increase and add the complexity of operation, and framework is owing to many connecting rods combine,
Globality and steadiness are the most poor.
2, the rigidity of universal joint is weaker, during when plus load is excessive or by heavier colliding with
Dig-in resistance surface between screw and bulb and there will be deformation, and then occur relatively sliding, and later
Again or when being repeatedly subjected to external force, this slippage can be increasing, finally boils solid failure.
Summary of the invention
The technical problem to be solved is to provide a kind of facilitating operation, easily dimmable and fixed stably
Qualitative strong calcaneus replacement and fixation support, with the deficiency overcoming prior art to exist.
For solving the problems referred to above, the present invention adopts the following technical scheme that:
A kind of calcaneus replacement and fixation support, it is characterised in that: include annulus and the shin being positioned on annulus
Bone fixes pin gripping seat, nut bone fixes pin gripping seat, calcaneus is fixed pin and gripped seat and fixing pin；Institute
State tibia to fix pin and grip seat, nut bone and fix pin and grip seat and calcaneus is fixed pin and gripped seat and all include the
One regulating block, the second regulating block, screw mandrel and for gripping the chuck of pin, described first regulation
Having bottom block and hold longitudinal chute that annulus penetrates, top has horizontal concrete chute, and sidepiece connects first
Nut block, has the horizontal slide rail embedding described horizontal concrete chute bottom described second regulating block, sidepiece is even
Being connected to the second nut block, described screw mandrel is located in described first nut block and the screwed hole of the second nut block
In, the hand of spiral of the screwed hole of described first nut block and the second nut block is contrary；Described chuck by
The first fixture block being bolted and the second fixture block are constituted, and described first fixture block passes through bolt with described
The termination of the second regulating block connects formation cradle head, described first fixture block and described second fixture block and engages
Fixing pin clamping hole is formed at face.
In invention has embodiment, described longitudinal chute is T-slot, and the cross section of described annulus is
The T-shaped structure adaptive with described T-slot, described horizontal concrete chute is dovetail groove, and described horizontal slide rail is
The dovetails adaptive with described dovetail groove.
There is on described annulus the convex eaves in both sides at there is breach form the entrance position of described first regulating block
Put.
Described tibia fixes pin gripping seat and described nut bone is fixed pin and gripped the first fixture block of seat for by first
Horizontal block, first indulging the one zigzag structure that block and the second horizontal block are constituted, described first horizontal block is with described
Second regulating block connects, and described second horizontal block is combined formation described fixing pin clamping with described second fixture block
Hole；Described calcaneus is fixed pin and gripped the first fixture block of seat is that the 3rd horizontal block and second is indulged block and purchased the one of composition
The T-shaped structure of body, described second indulges block and the second fixture block combination formation described fixing pin clamping hole.
Using technique scheme, the calcaneus that the calcaneus replacement and fixation support of the present invention has the present invention is multiple
It is strong etc. a series of that position fixed support has simple in construction, facilitating operation, easily dimmable and stability maintenance
Advantage.
