Description
Technical field
The present invention relates to a kind of Micro trauma hip replacement surgery instrument and its application method, more particularly to a kind of hip joint
The guidance system and its application method of displacement.
Background technology
The transformation to Bio-psycho-social Medical Mode and surgical disease wholistic therapy idea with new medical model
Formation, promoted the development of Micro trauma surgery, Micro trauma replacement of total hip is a kind of new hand for just occurring in recent years
Art method, it is by operative approach, operating method and operation tool on the basis of traditional replacement of total hip
Improve, complete in the relatively small otch (5~10cm) to the displacement of articular prosthesis, it is necessary to doctor's rich experience and
The improvement of operating theater instruments is obtaining good surgical effect.Therefore requirement higher is proposed to instrument, it is desirable to be capable of achieving enough
Surgical field of view, reduce operating time, accurately position.Compared with traditional replacement of total hip, minimally invasive surgery has damage
The advantages of wound is small, recovery is fast, function of joint is kept.Traditional THA (put by total hip arthroplasty, full hip-joint
Change) operative incision is usually 20~30cm, although possessing good surgical field of view, also bring it is substantial amounts of lose blood with it is postoperative compared with
It is prolonged to recover.In this respect, minimally invasive surgery then has obvious advantage, referring specifically to document 1：Zheng Dong, Yang Shuhua, it is micro-
Wound replacement of total hip progress, foreign medical science osteology fascicle the z6 volumes the 1st phase of January in 2005.
Total hip replacement minimally invasive surgery enters path method various, mainly include two incision approach, Anteroposterior aproach or
Anterior approach, posterior approach or posterolateral approach, referring specifically to document 2：Kelmanovich D, Parks ML, Sinha R, et
Al.J South Orthop Assoc, 2003；12(2)：90~94.Micro trauma two incision approach row total hip joint, using spy
Different apparatus and perspective are aided in, and more preferably, patient recovers faster security, and prosthese position is more accurate；But in polishing and acetabular bone or stock
Aided in C arm machine at any time in bone prosthese placement process, can cause to increase the irradiation time of doctor, referring specifically to document 3：
Berger R Paper presented at：70th Annual Meeting of the American Academy of
Orthopaedic Surgeon, 2003.It is still the test to surgical technic to implement this kind of operation in addition, and operator needs
Good technology and equipment condition.Front side approach needs to complete operation by drag hook and traction table traction, need to use special operation
Bed；Uncommon preceding road exposure chamber, doctor's learning curve is long；Acetabular bone limited view；Usually using special femoral stem；Need to use
Band eccentric throw prosthese driver；Locomotive activity test is limited in scope in art；Often there is femur and fracture of ankle joint in art.Preceding outside
Approach, there is provided intuitively acetabular bone appears, is easy to adjust acetabular bone position repeatedly in art, but part abductor cuts off, and has
Limping may be caused.And the capsular ligament on front side of whole is cut, account for the 30%~40% of whole capsular ligament, it is also possible to cause postoperative
It is unstable.Rear side approach is the most commonly seen operative approach that Micro trauma THA is used, and this operative approach is similar to tradition
Posterior approach THA, thus be a kind of minimally invasive surgery method that operative doctor learns to be easiest in such surgical procedure grasp, have much
It is representative.This unique surgical technic can complete operation tool of the orthopedist after improving.General rear outside is micro-
Trauma operation, otch is small, amount of bleeding reduce, the approach femur side appear with it is easy to operate.But acetabular bone exposes insufficient, backward dislocation
Probability is higher, injury of sciatic nerve is subject matter, and because cut-away portions muscle is still in art, thus can not can be regarded as real
Minimally invasive surgery.But if improving tool design, soft tissue is not cut off and completes operation technique, it will realize real minimally invasive
Hinder surgical technic.
The dislocation of hip joint is still the major complications for being only second to prosthetic loosening after other replacement of total hip.It is soft in operation
Disorganization is excessively its one of the main reasons, and this is just increasingly recognized by surgeon.Maintain the stability of hip joint main
It is static(al) and dynamical stability structure.External ligament increases static stability in capsular ligament structure and joint, and dynamical stability structure is hip
The abundant muscle tone of periarticular and anti-tensile force intensity.Capsule ligament can guide the proper motion of articular surface and limit
The effect of motion is spent, significantly prevents any unphysiologic displacement from occurring, be the important feature for stablizing hip joint.Therefore
In minimally invasive surgery, the reservation to ligament, muscle, capsular ligament is the importance of successful surgery, can maintain the steady of joint
It is qualitative.
Due to minimally invasive surgery otch very little, the smaller then scar of otch is smaller.But this is not after all the final mesh of Micro trauma THA
, if minimally invasive surgery mode to operative doctor objectively accurately processing acetabular bone and femur brings very big difficulty, or
Operator's ability is limited and successfully cannot performed the operation in narrow space, then the operation of blindness will cause a series of
Complication, such as prosthese place unreasonable, fracture or neurotrosis, postoperative ankle dislocation or prosthetic joint face premature abrasion etc..Cause
And in practical operation, Micro trauma THA operations propose requirement higher to instrument, because otch is small, it would be desirable to be able to expose acetabular bone
Fully, retain ligament, muscle, capsular ligament completely and backward dislocation probability is the requirement such as zero, the surgical effect that could have been obtained.Cause
This, the operation of Micro trauma total hip replacement proposes requirement higher to special improved operation tool, and acetabular bone can be made sudden and violent
Dew fully, without backward dislocation occurs, do not cut off muscle, retain complete shutdown capsule, accurately positioning etc. require, presently relevant patent
The Micro trauma instrument being related to, it is complicated to there is application method, not easy to remove, or the shortcomings of take up space big, existing instrument can not expire
Foot is all required.
