Description
Technical field
This utility model relates to a kind of Wicresoft and hinders hip replacement surgery instrument, relates in particular to a kind of guider of direct insertion hip replacement.
Background technology
Along with new medical model is to the transformation of biologic and psychogenic society medicine pattern and the formation of surgical diseases wholistic therapy idea, promote the development of Liao Wei the traumatology department, it is a kind of new operation method just occurring in recent years that replacement of total hip is hindered by Wicresoft, 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 instrument is had higher requirement, requirement can realize enough surgical field of view, reduces operating time, accurately location.Compare 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, has also brought a large amount of losing blood and the recovery of postoperative long period.In this respect, minimally invasive surgery has obvious advantage, specifically referring to document 1: Zheng Dong, and Yang Shuhua, are replacement of total hip progress, foreign medical science hindered by Wicresoft? 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 multiplely, mainly comprises two incision approach, front lateral approach or anterior approach, posterior approach or posterolateral approach, specifically referring to document 2:Kelmanovich D, Parks ML, Sinha R, et al.J South Orthop Assoc, 2003; 12 (2): 90～94.The capable total hip joint of two incision approach is hindered by Wicresoft, adopts special instrument and perspective auxiliary, and safety is better, and it is faster that patient recovers, and prosthese position is more accurate; But with C arm machine, assist at any time in polishing and acetabular bone or femoral prosthesis put procedure, can cause increasing doctor's irradiation time, specifically referring to document 3:Berger R Paper presented at:70th Annual Meeting of the American Academy of Orthopaedic Surgeon, 2003.Implement in addition this class operation and remain the test to surgical technic, operator need to have good technology and equipment condition.Front side approach need to, by drag hook and extension table traction complete operation, need to use special operation table; Uncommon front road exposure chamber, doctor's learning curve is long; The acetabular bone visual field is limited; Conventionally use special femoral stem; Need to use band eccentric throw prosthese driver; In art, locomotive activity test is limited in scope; Femur and ankle joint fracture in normal generation art.Front lateral approach, provides acetabular bone intuitively to appear, and be convenient in art, acetabular bone position be adjusted repeatedly, but the cut-out of part abductor likely causes limping.And cut the joint capsule of whole front sides, and account for 30%～40% of whole joint capsule, also may cause postoperative unstable.Rear side approach is that the most common operative approach that THA adopts is hindered by Wicresoft, and this operative approach is similar to traditional posterior approach THA, because of but operative doctor learn to hold a kind of wield minimally invasive surgery method most in this type of operation process, have much representativeness.The surgical technic of this uniqueness can make orthopedist complete by the operation tool after improving.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, thereby 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, will realize real minimally invasive surgery technology.
After replacement of total hip, dislocation of hip joint is still the major complications that is only second to prosthetic loosening in addition.In operation, soft tissue destruction is too much its one of the main reasons, and this is familiar with by surgeon just day by day.The stability that maintains hip joint is mainly static(al) and dynamical stability structure.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, particularly importantly stops any unphysiologic displacement to occur, and is the important structure of stablizing hip joint.Therefore in minimally invasive surgery, to the reservation of ligament, muscle, joint capsule, be the importance of successful surgery, can maintain the stability in joint.
Because minimally invasive surgery otch is very little, the less cicatrix of otch is less.But this after all Bu Shi Wicresoft hinder THA final purpose, if minimally invasive surgery mode accurately processes acetabular bone objectively to operative doctor and femur brings very large difficulty, or operator ability is limit and cannot successfully at narrow space, be performed the operation, operation so blindly will cause a series of complication, as prosthese is placed unreasonable, fracture or nerve injury, postoperative stremma or prosthetic joint face wearing and tearing too early etc.Thereby in practical operation, Wicresoft hinders THA operation instrument is had higher requirement, because otch is little, need to make acetabular bone to expose fully, retain ligament, muscle, joint capsule is complete and backward dislocation probability is the requirement such as zero, the surgical effect that could obtain.Therefore, Wicresoft hinders total hip replacement operation the improved operation tool of special use is had higher requirement, can make acetabular bone expose fully, without backward dislocation occur, do not cut off muscle, retain complete shutdown capsule, the requirement such as location accurately, instrument is hindered by the Wicresoft that Patents relates at present, exist using method complicated, not quick detachable, or the shortcoming such as large that takes up space, existing instrument can not meet whole requirements.
