Description
Technical field
This utility model relates to surgical patch field, particularly, relates to the segmentation Weaving type artificial bone-head for shoulder that nano coating modifies and to tuck inside the sleeve sticking patch.
Background technology
Rotator cuff tear is common Shoulder joint, and sickness rate increases with advancing age and gradually.Rotator cuff tear is the common cause causing the reduction of shoulder arthralgia, mobility, miopragia, accounts for 60% of shoulder pathological changes.To through the invalid Patients with Rotator Cuff Injury After of expectant treatment and shoulder sleeve mass lesions patient, usually take surgical operation therapy to repair and tear tendon, thus ease the pain, and rebuild function of joint.
Tendon is the weak spot in shoulder sleeve repair process, especially when defect is larger, tractive in art the shoulder tissue sleeve attempting bulk to tear be fixed on injured before former attachment point comparatively difficult, when now needing to solve huge rotator cuff tear by shoulder sleeve structure enhancement techniques, head of humerus covers not enough problem, ensure the mechanical property of kposthesis back porch tissue sleeve, maintain stability and the function of shoulder joint.
Repairing the material of enhancement techniques much for takeing on sleeve at present, comprising autologous tissue, allohisto compatibility, heteroplasm and synthetic tissue etc., but all there is respective problem and application limitation in clinical practice.Autograft material is mainly derived from the tissues such as autologous fascia lata, tendon of long head of biceps brachii, autograft class sticking patch great advantage has good biological attribute, the general inflammatory reaction not causing body, extra wound may be brought to autologous when one of major defect is to draw materials, belong to " tearing Dong Qiang open; mend Xi Qiang ", shoulder joint stability can be affected for district's disease damage.Tissue graft material that allogeneic is undressed derives from homology shoulder tissue sleeve, allosome kneecap tendinous tissue, heel string tissue and quadriceps femoris tendon tissue etc. usually.The mechanical property guarantee that this kind of material shortage is stable, easily makes body produce immunoreation, there is the risk infecting infectious disease after transplanting, and limited source.Acellular tissue graft material class sticking patch mainly comprises two kinds: heteroplasm transplants: be mainly derived from the tissues such as the corium of animal, small intestinal, pericardium, as Restore, and Cuffpatch, Conexa, TissueMen etc.2. allograft: the dermal tissue or the fascia lata that are mainly derived from human skin.After physical method or the operation of chemical method acellular, although have good biocompatibility and the mechanical characteristic of stretch-proof, but because it is tissue-derived, the difference of processing method, sterilizing methods, the Mechanical loading intensity that its mechanical strength carries well below the primary tendon of human body or ligament.From biomechanics and biology angle, it does not have the inherent character of tendon itself.
Current shoulder sleeve patching material, the factors such as biomechanical strength, histocompatibility, source of drawing material problem, safety and expense all limit its application clinically.Therefore design mechanical strength excellent, the shoulder sleeve sticking patch of simulation shoulder tissue sleeve, good biocompatibility has important clinical value for treatment rotator cuff injury.
