Abstract
The lower tibiofibula combined hook bolt is characterized by that it is formed from hook ring portion and sleeve barrel, the described hook ring portion is formed from hook ring and screw rod which are mutually connected into a J-form, and the screw rod can be screwed together with sleeve barrel. Wherein the shackle is semicircular, and the section of the shackle is formed by closing a minor arc and an inward concave arc; the tail end of the sleeve is a semicircular or trapezoidal conical raised head, and an inner hexagonal hole for the inner hexagonal wrench to be sleeved in is formed in the raised head. The utility model discloses utilize hook ring portion screw rod and sleeve to play the fixed effect that shin fibula is united under with the pulling force after closing soon, its "J" shape open-ended shackle has certain elasticity, can allow the fibula to move outward and rotatory in the certain limit, and both firm fixed accords with bone and joint biology elastic fixation principle again, does benefit to the motion that resumes normal ankle joint and the early healing of ligament, has avoided the emergence of ankle joint traumatic arthritis, is favorable to the ligament to be restoreed. The operation is simple, the implantation is convenient, the tissue stripping is less, no incision is needed, the operation wound is small, and the device is particularly suitable for patients with soft leg tissue defects.
Description
Technical field:
This utility model relates to medical apparatus and instruments, is specifically related to be in the orthopaedic trauma treatment ankle fracture and the employed a kind of medical internal fixation apparatus of ligament injury.
Background technology:
Ankle fracture merges the damage of lower tibiofibula combined ligament, is the orthopaedics common disease, treats when untimely or incorrect, often leaves over injury pain, joint instability, and the secondary traumatic arthritis influences ankle joint function.Being used for the classical western medical treatment method of ankle fracture merging lower tibiofibula combined ligament damage is the open reduction internal fixation, fixing with the common cortical bone screw of the normal selection of equipment, it reaches fixedly purpose by penetrating at least three layers of cortical bone of fibula and tibia, its advantage is to use simple and easy to do, is one of main method of present western medical treatment; Its shortcoming is to have limited the variation of ankle cave width and the physiological rotation of fibula, does not meet the biological nature of ankle joint.The selection of other treatment fixation device comprises lower tibiofibula associating hook, lower tibiofibula bolt, " ∏ " staple and polyester doublet cord etc. that German Link company makes.Also there are many disputes in these methods in treatment, mainly concentrate on: (1) is the indication of lower tibiofibula associating fixedly; (2) selection of inside-fixture; (3) post surgery treatment etc.There is restriction ankle cave width respectively in above-mentioned internal fixation apparatus, easily causes the difficult adjusting of traumatic arthritis, ligament rapture and elasticity, pair to damage defectives such as big.
The utility model content:
Technical problem to be solved in the utility model is to overcome the deficiency that above inner fixing device exists, and a kind of bone and joint flexible fastening biology principle of meeting is provided, and is beneficial to the motion of the normal ankle joint of recovery and the immediate union lower tibiofibula associating hook bolt of ligament.
Technical problem of the present utility model is by adopting following technical scheme to solve.It is characterized in that it is made up of shackle portion and sleeve, described shackle portion is interconnected to " J " shape by shackle and screw rod, the screw rod external process have can screw with the female thread processed in the sleeve outside screw thread, wherein shackle is semicircle, its cross section is that minor arc and the camber line sealing that concaves form; The sleeve tail end is semicircle or terraced taper plush copper, be processed with in it can make inner hexagon spanner be inserted within hexagon ring.
This utility model utilizes the pulling force after screw rod and internal thread of sleeve screw in the shackle portion and plays the fixedly effect of lower tibiofibula associating, the shackle of its " J " shape opening has certain elasticity after bearing certain pressure, can allow that fibula is outer within the specific limits to be moved and rotate.Therefore, existing strong fixedly advantage meets B﹠J flexible fastening biology principle again, is beneficial to the motion of the normal ankle joint of recovery and the immediate union of ligament, has avoided the generation of ankle joint traumatic arthritis, helps ligament repair.This utility model is simple to operate, insert conveniently, tissue is peeled off fewly, do not need to do otch in addition, and operation wound is little, be particularly suitable for shank soft tissue defects person, the operation back allows early ambulant and heavy burden, and fracture and ligament are healed in functional exercise, and function of joint is recovered in union of fracture.It has overcome the shortcoming that lower tibiofibula fixation device commonly used at present exists, and is a kind of more practical, more science, better lower tibiofibula associating internal fixation apparatus.
Description of drawings:
Fig. 1 is this utility model structure embodiment sketch map;
Fig. 2 is this utility model shackle sectional view;
Fig. 3 is this utility model user mode figure.
The specific embodiment:
As shown in Figure 1, this utility model is made up of shackle portion 1 and sleeve 2, and described shackle portion 1 is interconnected to " J " shape by shackle 1-2 and screw rod 1-1, is used to hook down fibula 5, makes itself and following tibia 4 gangs.Wherein screw rod 1-1 segment length is 18～22mm, diameter is 2.5～3.5mm, its external process has external screw thread, and sleeve 2 length are 25～35mm, and diameter is 5.5～6.5mm, be processed with female thread in the 2-1 of its bar portion, can go up external screw thread with screw rod 1-1 and screw, tail end is made semicircle or terraced taper plush copper 2-2, be processed with in it can make inner hexagon spanner be inserted within hexagon ring 2-3, inner hexagon spanner is placed in inner hexagonal hole 2-3 internal rotation, sleeve 2 can be combined in the shackle portion 1.As shown in Figure 2, shackle 1-2 is the semicircular arc of diameter 20mm, and its cross section is the face of minor arc and the camber line sealing composition that concaves, and has certain elasticity.
This utility model is made by medical stainless steel 317L material, has the good human-body biological compatibility, when heavy burden 30kg, can rely on the elasticity of shackle 1-2 to make fibula 5 outwards move 2mm.Because of it has certain elasticity, and can make ankle cave width respective change, recover the fine motion function of tibia 4 hypomeres and fibula 5 hypomeres associating with the ankle joint heavy burden.
Specific embodiment: as shown in Figure 3, when this utility model uses the medical 317L stainless steel of diameter 4.5mm is curved the semicircle shackle 1-2 of diameter as 20mm, screw rod 1-1 section processes the external screw thread of diameter 3mm.In being the sleeve 2 of 6mm, internal diameter 3mm, external diameter processes female thread.Sleeve 2 forms lower tibiofibula associating structure bolt with shackle 1-2 by threaded engagement.During use, be positioned at 2cm level place, ankle joint top, punch with the 6mm drill bit from tibia 4 outsides, then pad 3 is placed in sleeve 2 outsides, to avoid sleeve plush copper 2-2 to enter in the tibia 4, insert sleeve 2 again, shackle 1-2 is hooked fibula 5 from the outside, with spanner sleeve 2 is screwed on the shackle 1 screw rod 1-1 of portion, be threaded to when the ankle breadth degree equates with naturalness and get final product.
