Description
Technical field
The present invention relates to a kind of Micro trauma hip replacement surgery instrument, particularly relate to a kind of guider of direct insertion hip replacement.
Background technology
Along with the transformation of new medical model to Bio-psycho-social Medical Mode and the formation of surgical diseases wholistic therapy idea, promote the development of Micro trauma surgery, Micro trauma replacement of total hip is a kind of new operation method just occurred in recent years, it is by the improvement to operative approach, operational approach and operation tool on the basis of traditional replacement of total hip, in a relatively little otch (5 ~ 10cm), complete the displacement to articular prosthesis, need the improvement of doctor's rich experience and operating theater instruments to obtain good surgical effect.Therefore have higher requirement to instrument, requirement can realize enough surgical field of view, reduces operating time, locates accurately.Compared with traditional replacement of total hip, minimally invasive surgery has the advantages such as damage is little, recovery is fast, function of joint is kept.Traditional THA (total hip arthroplasty, total hip replacement) operative incision is generally 20 ~ 30cm, although have good surgical field of view, also brings a large amount of losing blood and the recovery of postoperative long period.In this respect, minimally invasive surgery then has obvious advantage, and specifically see document 1: Zheng Dong, Yang Shuhua, Micro trauma replacement of total hip progress, foreign medical science orthopaedics and tranmstology fascicle in January, 2005 z6 rolled up for the 1st phase.
Total hip replacement minimally invasive surgery enters path method to be had multiple, mainly comprises two incision approach, Anteroposterior aproach or anterior approach, posterior approach or posterolateral approach, specifically see document 2:Kelmanovich D, Parks ML, SinhaR, et al.J South Orthop Assoc, 2003; 12 (2): 90 ~ 94.The capable total hip joint of Micro trauma two incision approach, adopt special instrument and perspective to assist, safety is better, and patient recovers faster, and prosthese position is more accurate; But assist by C arm machine at any time in polishing and acetabular bone or femoral prosthesis put procedure, the irradiation time increasing doctor can be caused, specifically see document 3:Berger R Paper presented at:70th Annual Meeting of theAmerican Academy of Orthopaedic Surgeon, 2003.Implement this kind of operation in addition and remain test to surgical technic, operator needs good technology and equipment condition.Front side approach needs, by drag hook and extension table traction complete operation, need use special operation table; Uncommon front road exposure chamber, doctor's learning curve is long; Acetabular bone limited view; The special femoral stem of usual use; Band eccentric throw prosthese driver need be used; In art, locomotive activity test is limited in scope; Femur and ankle joint fracture in normal generation art.Anteroposterior aproach, provides acetabular bone intuitively and appears, and is convenient to repeatedly adjust acetabular bone position in art, but part abductor cuts off, and likely causes limping.And cut the joint capsule of all front sides, account for 30% ~ 40% of whole joint capsule, also may cause postoperative instability.Rear side approach be Micro trauma THA adopt a most common operative approach, this operative approach is similar to traditional posterior approach THA, because of but operative doctor learn in this type of operation process, to hold a kind of wield minimally invasive surgery method most, have much representativeness.The surgical technic of this uniqueness can make orthopedist be completed by the operation tool after improvement.General rear outside minimally invasive surgery, otch is little, and amount of bleeding reduces, and this approach femur side appears with easy to operate.But acetabular bone exposure is insufficient, backward dislocation probability is higher, injury of sciatic nerve is subject matter, and because still want cut-away portions muscle in art, thus can not can be regarded as real minimally invasive surgery.If but improve tool design, do not cut off soft tissue and complete operation technique, real minimally invasive surgery technology will be realized.
After replacement of total hip, dislocation of hip joint is still the major complications being only second to prosthetic loosening in addition.In operation, soft tissue destruction is too much its one of the main reasons, this just day by day be familiar with by surgeon.Maintain stability mainly static(al) and the dynamical stability structure of hip joint.Joint capsule structure and intraarticular external ligament increase static stability, and dynamical stability structure is muscle tone and the tension stress intensity of hip joint rich surrounding.Capsule ligament can guide the proper motion of articular surface and the effect of limit excessive motion, and significantly stoping any unphysiologic displacement to occur, is the important feature of stable hip joint.Therefore, in minimally invasive surgery, be the importance of successful surgery to the reservation of ligament, muscle, joint capsule, the stability in joint can be maintained.
Because minimally invasive surgery otch is very little, the less then cicatrix of otch is less.But this is not Micro trauma THA final purpose after all, if minimally invasive surgery mode accurately processes acetabular bone and femur brings very large difficulty objectively giving operative doctor, or operator ability is limit and cannot successfully perform the operation at narrow space, operation so blindly will cause a series of complication, as prosthese is placed unreasonable, fracture or nerve injury, postoperative ankle dislocation or prosthetic joint face premature abrasion etc.Thus in practical operation, Micro trauma THA operation is had higher requirement to instrument, and because otch is little, needs can make acetabular bone expose fully, retain ligament, muscle, joint capsule are complete and backward dislocation probability is the requirement such as zero, the surgical effect that could obtain.Therefore, the operation of Micro trauma total hip replacement is had higher requirement to the operation tool of special improvement, acetabular bone can be made to expose fully, without backward dislocation occur, do not cut off muscle, retain the requirements such as complete shutdown capsule, accurately location, the Micro trauma instrument that current Patents relates to, there is using method complexity, not quick detachable, or the shortcoming such as large that takes up space, existing instrument can not meet whole requirement.
