Description
Technical field
The present invention relates to medical domain, further to a kind of surgical apparatus and operation method and in particular to one kind
Fibula dry osteotomy operation retractor assembly and its operation method.
Background technology
Fibula is one of two block length bones on people and vertebratess (Tetrapoda) shank, positioned at the lateral part of shank, tibia
Outer rear, elongated, it is divided into one and two ends.Found under gravity because fibula is to outside platform by clinical observation
Support, lead to relatively weak medial tibial plateau that differential settlement occurs, cause genu varum and medial gap to narrow, fibula is high
Outside the osteotomy ossa tibiale posterius of position, platform loses the support of fibula, moves outside load during heavy burden, mitigates the stress inside knee joint and mitigates knee joint
The symptom of joint osteoarthritis pain.At present the position of fibula osteotomy is selected in below capitulum fibulae 6-8cm mostly, leads to
Carry out osteotomy frequently with osteotome, goose saw or scroll saw.But because at osteotomy, fibula sclerotin is very rigid, osteotomy operation is extremely difficult.
Currently without preferable soft tissue retractor, often using goitre retractor, soft tissue is retracted, generally require several operations
Assistant's joint operation.It is just deep peroneal nerve position out of shape at osteotomy, because goitre retractor cannot be fixed, in actual operation simultaneously
During and the soft tissue easily to operation near sites, particularly deep peroneal nerve causes irreversible injury.Also can make to perform the operation
In journey, the spirit of medical personnel is highly tight, not only makes surgical inefficiency, and it is not good, to medical care to be easily caused surgical effect
The mind ＆ body dual state of personnel is also no small test.It is first to use retractor therefore for preferably osteotomy mode herein
Soft tissue is protected, then carries out multidirectional boring so as to form weak area using 2.0mm Kirschner wire at osteotomy position,
Carry out osteotomy using osteotome or rongeur in weak area afterwards, be greatly improved procedure efficiency and processing safety.
Content of the invention
Easily the soft tissue of operation near sites is caused to damage to solve the operation of above-mentioned existing fibula dry osteotomy
The problems such as wound, the pressure that procedure efficiency is not high and doctors and patients bear are all very big, the invention provides a kind of dry osteotomy of fibula
Operation retractor assembly and its operation method, concrete scheme is as follows：
A kind of dry osteotomy operation retractor assembly of fibula, described traction device assembly includes pull device and fixing dress
Put, described pull device includes middle the first hinged linking arm and the second linking arm, described first linking arm and institute
The two ends stating the second linking arm are shaped to working end and handle end, the work of described first linking arm and described second linking arm respectively
Form substrate as end, toward relative direction bending, described substrate is equipped with two relative sides for the bottom of described substrate
Plug socket and fixing lug boss, described pull device also includes the accessory plate with plug socket cooperating；The number of described fixing device
Amount at least two, described fixing device includes the body of arc, and one end of described body is provided with company corresponding with fixing lug boss
Connect boss.
Further, the inwall of described plug socket forms some first spacing preiections, described accessory plate and plug socket
The position of cooperating forms second spacing preiection corresponding with the first spacing preiection.
Further, the intermediary form of described fixing device body has the horizontal projection along horizontal plane direction, described convex
Fibula location hole is offered, described body is provided with some kirschner needle guide holes on rising.
Further, described kirschner needle guide hole is more than the taper pore structure in top surface aperture for bottom surface aperture.
Further, the top surface of described fixing lug boss forms some 3rd spacing preiections, the bottom surface of described connection boss
Form the 4th spacing preiection of some and described 3rd spacing preiection cooperation.
Further, described connection boss offers bolt hole, the position of corresponding described bolt hole in described fixing lug boss
Put and offer blind hole, described bolt in the hole is provided with bolt.
Further, described fixing lug boss is arranged on the relative side of described substrate by boss seat, described boss seat
Thickness be more than described plug socket thickness.
Further, described linking arm handle end is provided with stopping means.
A kind of dry osteotomy operation method of fibula is it is characterised in that the method comprising the steps of：
Step1. take the surgery location row longitudinal incision at capitulum fibulae 6-8cm, cut skin, subcutaneous tissue and deep muscle
Film, is carried out to art mouth after hemostasis process, from peroneus longus separate with musculus soleus gap appear fibula do, note appearing and protect
Deep peroneal nerve；
Step2., with the help of goitre retractor, the parallel fibula of piece will be strutted and be positioned in otch, and strut piece bottom and put
Below fibula and pairing, deep peroneal nerve is made to be located at outside dilator scope, then insertion accessory plate retracts soft group on strutting piece
Knit and so that visual area is fully exposed, then spacing with the stopping means on handle end；
Step3. 2 fixing devices are respectively placed in corresponding fixing lug boss and tighten fixing bolt, be then threaded into
Bolt withstands fibula to bolt, so that dilator and fibula is kept relative stability；
Step4. Kirschner wire by the pilot hole in fixing device to holing at fibula osteotomy after, screw out positioning spiral shell
Bolt, takes out fixing device, using rongeur and osteotome, fibula specified location is carried out with osteotomy, osteotomy stump is inserted gelfoam and stopped
Blood；
Step5. release the spacing of pull device, take out pull device；
Step6. normal saline flushing otch, layer-by-layer suture otch, place 1 piece of drainage strip, postoperative antiinflammatory, pain relieving are suited the medicine to the illness and located
Reason.
The beneficial effects of the present invention is：A kind of dry osteotomy operation retractor assembly of fibula proposed by the present invention and its
Fibula to be performed the operation is separated with blood vessel below and nervous system by operation method using the substrate that bottom all bends inwards,
Avoid in operation process, the various soft tissues below fibula being caused to damage, accessory plate is located at the top of substrate by plug socket,
Soft tissue for pushing operative site both sides open exposes operative site, and the reasoning due to art mouth both sides soft tissue, make to add
The spacing preiection of piece bottom is firmly stuck in the spacing preiection in plug socket Nei it is ensured that its stability in operation process；Handss
During art, it is respectively arranged at using two groups of fixing devices and treats above and below surgery location, and utilize fixing device each group
The effect of part is it is ensured that retract the stability in operation process for the device assembly, and because kirschner needle guide hole is pyramidal structure, makes gram
Family name's pin can have certain adjustment angle scope from this pilot hole insertion needle, improves the efficiency of operation, the step simplifying operation.
