Abstract

The invention relates to a wrist joint movable connecting rod for fixing across a wrist joint, which comprises a metacarpal bone movable seat (2), a radius movable seat (2'), a metacarpal bone connecting rod (1) fixed on the metacarpal bone movable seat (2), a radius connecting rod (9) connected with the radius movable seat (2') and an elasticity-adjustable locking bolt (4) connecting the metacarpal bone movable seat (2) and the radius movable seat (2'). The wrist joint movable connecting rod for fixing across the wrist joint overcomes the defect that: when the surrounding of the wrist joint fractures, the conventional fixation of the wrist joint can cause blood supply obstacles and tissue ischemia and hypoxia of wrist joint surrounding tissues and further cause the disuse change of jointcapsules, ligaments, joint surrounding tissues and bones. The wrist joint movable connecting rod for fixing across the wrist joint can bring function exercise to the wrist joint earlier without affecting the fixation and the recovery of the fracture.

Description

跨腕关节固定的腕关节活动连接杆 Wrist across the wrist motion, a fixed connecting rod

技术领域 FIELD

[0001] 本发明涉及骨科医疗器械,具体是指一种跨腕关节固定的腕关节活动连接杆,它属于一种骨科外固定的连接杆。 [0001] The present invention relates to orthopedic medical device, specifically refers to a cross fixed wrist wrist motion, a connecting rod, which belongs to one kind of external orthopedic fixator connecting rod. 它适用于桡骨、尺骨远端骨折及腕关节周围的创伤治疗。 It is suitable radius, ulna and distal fractures of the wrist around the wound treatment.

背景技术 Background technique

[0002] 对于桡骨、尺骨远端各种类型的骨折及腕关节周围创伤,现有的主要治疗方法是内固定或外固定治疗。 [0002] For radial, various types of fractures of the distal ulna and wound around the wrist, the main treatment is a conventional internal fixation or external fixation. 内固定治疗创口大、出血多、手术时间长且操作复杂、不适合开放性骨折的治疗、需要二次手术取出内植物。 Internal fixation wound, bleeding, operation time is long and complex operations, is not suitable for treatment of open fractures, surgery to remove the need for secondary plant. 外固定治疗虽然有创口小、出血少、手术时间短、可满足开放性骨折的治疗、不需二次手术等优点,但由于外固定治疗桡骨、尺骨远端各种类型的骨折及腕关节周围创伤时,通常需要固定腕关节,制约了腕关节活动,致使腕关节不能得到早期锻炼。 Although external fixation has a small wound, less bleeding, shorter operative time, to meet the treatment of open fractures, without a secondary operation, etc., but since the outer radial fixation, various types of fractures around the wrist and the distal ulna when trauma, usually require a fixed wrist, wrist restricted activity, resulting in the wrist can not get an early workout. 由于固定时间太长(一般为4-6个月,甚至更长),往往治疗好了骨折,腕关节也发生僵硬,使得关节功能受损。 Since the fixed time is too long (usually 4-6 months, or even longer), often treated better fracture, wrist stiffness can also occur, making joint dysfunction.

[0003] 腕关节是由尺桡骨远端、8块腕骨及5块掌骨的近侧端形成的复杂关节,能够做共150°的前后屈伸和60°的内外侧屈,是手与臂之间的环绕装置,腕关节的功能障碍也会严重影响手部的灵活性。 [0003] ulnar wrist by the distal radius, the carpal complex joint 8 and a proximal end of the metacarpal 5 is formed, can be done before and after 150 ° of flexion and 60 ° of flexion and outside, between the hand and the arm is surround system, dysfunction of the wrist will seriously affect the flexibility of the hand.

[0004] 桡骨远端骨折腕关节附近的骨折最常见的是桡骨远端骨折,可以分成柯莱斯骨折(Colles骨折)、史密斯骨折(Smith骨折)、巴尔通骨折Oarton骨折)以及烧骨远端粉碎性骨折;其他的还有各类型的腕骨骨折和掌骨近端骨折,其中比较重要的是月骨骨折、手舟骨骨折和第一掌骨基底部骨折。 [0004] The distal radial fractures most common fractures near the wrist joint is distal radius fractures, fractures may be divided into Kelai Si (of Colles fractures), fractures Smith (Smith fracture), Barton fracture Oarton fracture) and the burning of the distal end fractures; there are other various types of wrist fractures and fractures of the proximal metacarpal, which is more important lunate bone fracture, scaphoid fractures and fractures of the base of the first metacarpal. 手舟骨骨折的固定范围需要包括肘关节和拇指掌指关节。 Fixed range scaphoid fractures and need to include the elbow joint of the thumb. 手舟状骨血供情况差,因而固定时间需长达3-4个月,并且还容易发生骨不连和骨坏死。 Blood supply scaphoid shape poor, and thus needs a fixed time for up to 3-4 months, and is also prone to osteonecrosis and nonunion.

[0005] 掌骨骨折常是手外伤直接暴力的结果,开放性骨折比例较高,且常伴有肌腱神经血管等的合并损伤,临床治疗方案须视具体情况决定,外固定范围一般需超过腕部。 [0005] metacarpal fracture is often the result of hand injuries direct violence, a high proportion of open fractures, tendon injury and is often accompanied combined blood vessels, nerves, clinical treatment decisions are subject to availability, normally it takes more than an outer arm fixed range .

[0006] 腕关节周围骨折时,腕关节的固定可引起腕关节周围组织供血障碍,使组织缺血,缺氧而导致关节囊、韧带、关节周围组织和骨的废用性改变,最终引起关节的纤维性强直和功能性障碍,虽然肢体关节去除制动后,关节周围组织血供恢复,加之关节轻微的活动,使组织的营养得到改善,使关节组织的退行性变逐渐恢复,但这种恢复极其缓慢。 [0006] around the wrist fractures when fixed around the wrist of the wrist may cause blood disorder tissue, tissue ischemia, hypoxia caused by the joint capsule, ligaments disuse, and periarticular bone tissue change, eventually causing joint fibrous ankylosis and dysfunction, although the limb and joint after removal of the brake, to restore blood supply around the joints, the joints together with a slight activity, improved nutritional tissue, so that degeneration of joint tissue gradually restored, but the recovery extremely slow.

[0007] 因此发明一种跨腕关节固定的腕关节活动连接杆,能使腕关节得到早期的功能锻炼,又不影响骨折的固定和恢复成为了一项迫切和重要的工作。 [0007] Therefore invent a fixed cross wrist joint wrist activity connecting rods, wrist can get early functional exercise, without affecting the fixed and restoration fractures become an urgent and important task.
