Description
Technical field
The present invention relates to a kind of Micro trauma hip replacement surgery instrument, more particularly, to a kind of direct insertion hip replacement
Guider.
Background technology
With new medical model to the transformation of Bio-psycho-social Medical Mode and surgical disease wholistic therapy idea
Formation, promoted the development of Micro trauma surgery, Micro trauma replacement of total hip is a kind of new hand just occurring in recent years
Art method, it is by operative approach, method of operating and operation tool on the basis of traditional replacement of total hip
Improve, complete the displacement to articular prosthesis in a relatively small otch (5～10cm), need doctor's rich experience and
The improvement of operating theater instruments is to obtain good surgical effect.Therefore instrument is put forward higher requirement it is desirable to can achieve 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 little, recovery is fast, function of joint is kept.Traditional THA (total hip arthroplasty, put by full hip-joint
Change) operative incision be usually 20～30cm, although having good surgical field of view, also bring substantial amounts of lose blood and postoperative relatively
Recover for a long time.In this respect, minimally invasive surgery then has obvious advantage, referring specifically to document 1：Zheng Dong, Yang Shuhua, micro-
Wound replacement of total hip progress, foreign medical science osteology fascicle the z6 volume the 1st phase of January in 2005.
Total hip replacement minimally invasive surgery enter path method have multiple, main 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 auxiliary, more preferably, patient recovers faster, and prosthese position is more accurate for security；But in polishing and acetabular bone or stock
Assisted with C arm machine at any time in bone prosthese placement process, can lead 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.In addition implement this kind of operation and remain the test to surgical technic, operator needs
Good technology and equipment condition.Front side approach needs to complete to operate by drag hook and traction table traction, need to use special operation
Bed；Uncommon front road exposure chamber, doctor's learning curve is long；Acetabular bone limited view；Special femoral stem is usually used；Need to use
Band eccentric throw prosthese driver；In art, locomotive activity test is limited in scope；Often there is femur and fracture of ankle joint in art.Front outside
Approach, there is provided intuitively acetabular bone appears, is easy in art, acetabular bone position be adjusted repeatedly, but the cut-out of part abductor, have
Limping may be caused.And cut the capsular ligament on front side of all, account for the 30%～40% of whole capsular ligament it is also possible to cause postoperative
Unstable.Rear side approach is the most commonly seen operative approach that Micro trauma THA adopts, 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
Representative.This unique surgical technic can make operation tool after improving for the orthopedist complete.General rear outside is micro-
Trauma operation, otch is little, amount of bleeding reduce, this approach femur side appear with easy to operate.But acetabular bone exposes insufficient, backward dislocation
Probability is higher, injury of sciatic nerve is subject matter, and because being still to cut-away portions muscle in art, thus can not can be regarded as real
Minimally invasive surgery.But if improving tool design, not cutting off soft tissue and completing operation technique, it will realize real minimally invasive
Hinder surgical technic.
In addition after replacement of total hip, the dislocation of hip joint is still the major complications being only second to prosthetic loosening.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.In capsular ligament structure and joint, external ligament increases static stability, and dynamical stability structure is hip
Muscle tone and anti-tensile force intensity that periarticular enriches.Capsule ligament can guide the proper motion of articular surface and limit
The effect of degree motion, significantly stops any unphysiologic displacement from occurring, is the important feature 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
Qualitative.
Due to minimally invasive surgery otch very little, the more little then scar of otch is less.But this is not the final mesh of Micro trauma THA after all
, if minimally invasive surgery mode is objectively accurately processing acetabular bone to operative doctor and femur brings very big difficulty, or
Operator's ability is limited and cannot successfully be performed the operation in narrow space, then the operation of blindness will lead to a series of
Complication, such as prosthese placement is unreasonable, fractures or neurotrosis, postoperative ankle dislocation or prosthetic joint face premature abrasion etc..Cause
And in practical operation, Micro trauma THA operation instrument is put forward higher requirement, because otch little it would be desirable to be able to make acetabular bone expose
Fully, ligament, muscle are retained, capsular ligament is complete and backward dislocation probability is the requirement such as zero, the surgical effect that could have obtained.Cause
This, the operation of Micro trauma total hip replacement is put forward higher requirement to special improved operation tool, and acetabular bone can be made sudden and violent
Dew fully, no backward dislocation occur, 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 using method, not easy to remove, or the shortcomings of take up space big, existing instrument can not be expired
Foot all requires.
Content of the invention
The technical problem to be solved is to provide a kind of guider of direct insertion hip replacement, can be accurate
Positioning, easily loads and unloads, efficiently and easily realizes the insertion of acetabular component, is press-fitted, and is prevented effectively from generation dislocation phenomenon, significantly subtracts
