Abstract
The present invention relates to a kind of locking external fixer for calcaneus fractures, belong to technical field of medical instruments.This locking external fixer is that L shape hollow is dull and stereotyped, the frame of L shape hollow flat board has the screwed hole for being screwed into screw.The present invention propose the locking external fixer for calcaneus fractures, belong to extenal fixation category, therefore wound little go out insufficiency of blood, otch reduces at double, only has 4cm, and along the direction of limbs, incision complication obviously reduces.Owing to being extenal fixation, therefore not needing second operation to take out calcaneus internal fixtion, avoid the risk of second operation, and save medical expense for patient.External fixer can adopt the lightweight materials such as rustless steel, titanium alloy or aluminium alloy, and less than traditional external fixer volume, lightweight, patient's misery is little, is conducive to the rehabilitation of patient's sick body.This locking external fixer, damages little, and nail road complication is less, improves the safety of operation.
Description
Technical field
The present invention relates to a kind of extenal fixation locking and fixing device for calcaneus fractures, belong to technical field of medical instruments.
Background technology
Fracture of calcaneus is common fracture, and operative treatment is main treatment means, and therapeutic purposes are fixed fracture site, and fixing means has internal fixtion and extenal fixation two kinds.Treatment means main clinically at present with plate screw as the internal fixtion of material, the shortcoming of internal fixtion is that operation wound face is large, otch not easily heals, therefore easily the complication such as infection are caused, and operation process is complicated, need even Repeated Operation treatment again, just can reach healing object.And traditional external fixer is also one for the treatment of means of fracture of calcaneus, but because the support body heaviness of external fixer, complicated operation, fixed effect are poor, easily loosen, therefore strongly limit the application of external fixer.
Summary of the invention
The object of the invention is to propose a kind of locking external fixer for calcaneus fractures, change the structure of the external fixer had for calcaneus fractures, to overcome the structural disadvantages of existing external fixer, simplify the therapeutic process of fracture of calcaneus, and effectively reduce the incision complication of calcaneus fractures.
The locking external fixer for calcaneus fractures that the present invention proposes, is characterized in that this locking external fixer is that L shape hollow is dull and stereotyped, the frame of L shape hollow flat board having the screwed hole for being screwed into screw.
The locking external fixer for calcaneus fractures that the present invention proposes, its advantage is:
1, locking external fixer of the present invention be used for external, belong to extenal fixation category, therefore wound little go out insufficiency of blood, otch reduces at double, only has 4cm, and along the direction of limbs, incision complication obviously reduces.
2, locking external fixer of the present invention is owing to being extenal fixation, does not therefore need second operation to take out calcaneus internal fixtion, avoids the risk of second operation, and saves medical expense for patient.
3, locking external fixer of the present invention can adopt the lightweight materials such as rustless steel, titanium alloy or aluminium alloy, and less than traditional external fixer volume, lightweight, patient's misery is little, is conducive to the rehabilitation of patient's sick body.
4, locking external fixer of the present invention, can adopt Kirschner Wire Drilling, compared with punching, damages little with traditional electric drill, and nail road complication is less, improves the safety of operation.
5, locking external fixer of the present invention, thin nail can be adopted to carry out many nails and fix, such as diameter is the screw 12-16 piece of 3.0mm, and it is little that such fixing means has wound, fixing reliable effect.
6, locking external fixer of the present invention, adopts thread lock structure to combine, instead of the connected mode of traditional external fixers such as nail clip, make its overall structure more firmly and volume less.
Accompanying drawing explanation
Fig. 1 is the structural representation of the locking external fixer for calcaneus fractures that the present invention proposes.
Fig. 2 is the structural representation for the screw making the locking external fixer support body for calcaneus fractures of the present invention and human body root synosteosis fix.
In Fig. 1 and Fig. 2,1 is that L shape hollow is dull and stereotyped, and 2 is screwed holes, and 3 is screw afterbodys, and 4 is in the middle part of screw, and 5 is that screw is most advanced and sophisticated.
Detailed description of the invention
The locking external fixer for calcaneus fractures that the present invention proposes, its structure as shown in Figure 1, this locking external fixer be L shape hollow flat board 1, L shape hollow flat board 1 frame on have screwed hole 2 for being screwed into screw.
Locking external fixer for calcaneus fractures of the present invention, by the advantages of traditional calcaneal steel plate and external fixer, according to the appearance profile of calcaneus, be designed to annular lock external fixer as shown in Figure 1, for fixing screw structure as shown in Figure 2, screw afterbody 3 and external fixer are by screwed hole combination lock, and screw tip 5 is screwed into human body calcaneus, with fixing fracture.There is Wicresoft, without features such as second operation taking-ups, effectively can reduce the incision complication of calcaneus fractures.
Locking external fixer for calcaneus fractures of the present invention, its operative process is as follows:
First by cut or closed prying and pulling mode resets fracture of calcaneus, with the temporary fixed fracture of Kirschner wire, perspective is lower confirms that the position of external fixation bone fracture plate is correct, with Kirschner Wire Drilling, then is screwed into the fixing fracture of screw.
Reliable in order to fixing intensity, suggestion screw is uniformly distributed, and interval screwed hole is screwed into screw, better effects if.
Significantly fracture for articular step-off, first open reduction articular surface bone grafting, with the fixing joint such as spring nail, Absorbable plate face, close otch, then place blade plate, the screw now below articular surface must be screwed into, to increase the support to articular surface.
For the fracture at calcaneal tuberosity place, emphasis is screwed into the screw in calcaneal tuberosity region, with fixing fracture, prevents displacement fracture under heel string tractive, the screw of adjacent domain all can be screwed into if desired, to increase the hold to sclerite.
The profile of calcaneus locking external fixer breast piece designs according to the appearance profile of calcaneus, and " annular " that become to close according to calcaneus configuration design, to fix calcaneus to greatest extent.
The material of the locking external fixer for calcaneus fractures of the present invention is positioned at external owing to not contacting skin, can be the lightweight materials such as rustless steel, titanium alloy or aluminium alloy.Support body is evenly distributed with screwed hole, and density is comparatively large, is convenient to the fixed position of doctor's unrestricted choice screw as required, alleviates support body weight simultaneously.Screw thread nail on support body, is characterized in that screwed hole and screw match, and allows that screw is two-way is screwed into, so that blade plate left and right foot is general.Screw is lock screw nail, is divided into most advanced and sophisticated stage casing and tail end, and tip band screw thread holds skeleton, and stage casing is smooth to be contacted with skin and soft tissue, and tail end has screw thread and blade plate combination lock.
