Description

分段编织仿生型人工肩袖补片 Segment woven bionic artificial rotator cuff patch

技术领域 FIELD

[0001] 本发明涉及外科补片领域,具体地,涉及分段编织仿生型人工肩袖补片。 [0001] The present invention relates to a surgical patch, and in particular, to a segment of the rotator cuff woven bionic artificial patch.

背景技术 Background technique

[0002]肩袖撕裂是常见的肩关节疾病,发病率随着年龄的增长而逐渐增加。 [0002] rotator cuff tear shoulder is a common disease, the incidence with age gradually increases. 肩袖撕裂是导致肩关节疼痛、活动度降低、功能减弱的常见原因,约占肩部病变的60%。 Rotator cuff tear is a common cause of shoulder pain, reduced activity, weakened, accounting for about 60% of shoulder lesions. 对经保守治疗无效的肩袖损伤患者及肩袖大面积损伤患者,通常采取外科手术治疗修补撕裂肌腱,从而减轻疼痛,并重建关节功能。 For conservative treatment fails in patients with rotator cuff injuries and shoulder sleeves patients with large areas of damage, usually take torn tendon repair surgery, thus reducing the pain and rebuild joint function.

[0003] 肌腱是肩袖修复过程中的薄弱点,尤其是缺损较大时,术中牵拉并试图将大块撕裂的肩袖组织固定于受伤前的原附着点较为困难,此时需要用肩袖结构增强技术解决巨大肩袖撕裂时肱骨头覆盖不足问题,保证修补术后肩袖组织的力学性能,维持肩关节的稳定性和功能。 [0003] rotator cuff tendon repair is a weak point in the process, especially in larger defects, the surgery and tried to pull chunks torn rotator cuff tissue fixation to the original attachment points before the injury more difficult at this time need enhancement technology to solve the stability and function of the shoulder joint of the humeral head covering when huge shortage rotator cuff tear, to ensure that the mechanical properties after repair of rotator cuff tissue, to maintain the structure with rotator cuff.

[0004]目前用于肩袖修补增强技术的材料很多,包括自体组织、同种异体组织、异种组织以及人工合成组织等,但在临床应用上都存在各自的问题及应用局限性。 [0004] rotator cuff repair materials currently used for many enhancement techniques, including autologous tissue, allogeneic tissue, xenogeneic tissue and synthetic organization, but in clinical applications there own problems and limitations apply. 自体组织移植材料主要来源于自体的阔筋膜、肱二头肌长头肌腱等组织,自体组织移植类补片最大优点是具有良好的生物属性,一般不引起机体的炎症反应,主要缺点之一在于取材时可能会给自体带来额外创伤,属于“拆东墙,补西墙”,供区病损会影响肩关节稳定性。 Autologous tissue graft material is primarily derived from autologous fascia lata, biceps tendon and other tissues, autologous tissue graft patch type big advantage is good biological properties, generally do not cause inflammation of the body, one of the main drawbacks could have drawn that when autologous bring additional trauma, are "split the east wall, pay Paul," the donor lesions affect the stability of the shoulder joint. 同种异体未加工组织移植材料通常来源于同源肩袖组织、异体髌腱组织、跟腱组织及股四头肌肌腱组织等。 Allogeneic tissue transplantation raw material usually derived from homologous rotator cuff tissue allograft patella tendon, Achilles tendon and quadriceps tendon organizations. 该种材料缺乏稳定的力学性能保证,移植后容易使机体产生免疫反应,存在感染传染性疾病的风险,且来源有限。 Lack of stable mechanical properties to ensure that this kind of material, post-transplant easily make the body produce immune responses, there is a risk of infectious disease, and limited sources. 脱细胞化组织移植材料类补片主要包括两种:异种组织移植:主要来源于动物的真皮、小肠、心包膜等组织,如Restore ,Cuffpatch,Conexa,TissueMen等。 Decellularized tissue patch graft material mainly include two categories: xenogeneic tissue transplantation: mainly derived from animal leather, small intestine, film pericardial tissue, such as Restore, Cuffpatch, Conexa, TissueMen like. ②同种异体组织移植:主要来源于人类皮肤的真皮组织或阔筋膜。 ② allogeneic tissue transplantation: mainly from human skin dermal tissue or fascia lata. 经物理方法或化学方法脱细胞化操作后,虽然具有良好的生物相容性及抗拉伸的力学特性,但因其组织来源、加工方法、灭菌方法的不同,其力学强度远远低于人体原生肌腱或韧带所承载的力学负荷强度。 Physically or chemically acellular operation, while having good biocompatibility and mechanical properties of tensile, but because of different tissue origin, processing method, sterilization methods, which is much lower than the mechanical strength mechanical load intensity human native tendon or ligament carried. 从生物力学和生物学角度讲,它并不具备肌腱本身的固有特性。 Biomechanical and biological perspective, it does not have the inherent characteristics of the tendon itself.

[0005]目前的肩袖补片材料,生物力学强度、组织相容性、取材来源问题、安全性和费用等因素均限制其在临床上的应用。 [0005] The current rotator cuff patch materials, biomechanics, tissue compatibility, drawn source of the problem, and security costs and other factors limit its use in the clinic. 因此设计力学强度优良,模拟肩袖组织、生物相容性好的肩袖补片对于治疗肩袖损伤有重要的临床应用价值。 So excellent mechanical strength design, simulation rotator cuff tissue, biocompatibility good rotator cuff patch has important clinical value in the treatment of rotator cuff injury.
