Description

A kind of distal tibiofibular involves ankle-joint external fixing rack

Technical field

The utility model belongs to medical equipment design field, is related to a kind of fixed frame, under especially a kind of tibiofibula Section involves ankle-joint external fixing rack.

Background technique

In human body unexpected injury, ankle strain is most high-incidence one of injury gained in sports.Ankle-joint is by shin bone and fibula Distal end and astragalus are constituted, and constitute ankle cave by medial and lateral malleolus and shin bone rear, and the saddle articular surface above astragalus is located in ankle cave, away from The saddle articular surface of bone is front wide and rear narrow, and when dorsiflexion, wider place entered ankle cave, and narrower part enters ankle cave when plantar flexion, so ankle-joint exists Plantar flexion position slightly loosens, and dissection and physilogical characteristics determine that ankle-joint is easier that varus eversion sprain occurs in plantar flexion.And because For the longer ankle cave of ankle-joint external malleolus fibula relatively depth, the shorter ankle cave of internal malleolus shin bone is shallower, therefore ankle-joint is easier to that varus strain occurs, More serious to cause dislocation, fracture etc., the treatment damaged at present to it mainly follows three principles: resetting, is fixed, function forging Refining, wherein it is fixed particularly important to healing and rehabilitation, if fixation is bad, easily there is obstinate, local deformation, limbs coordination Situations such as ineffective.Currently used fixing means has: plintlet, plaster bandage, outer external fixing rack, traction braking are fixed etc..

Such as (notification number: publication date: 20171024) CN206576998U discloses a kind of external fixation of fracture to Chinese patent Clamping plate, front plate, rear plate, inside clamping plate, outside clamping plate and fixation kit including being in 45 degree；When the wounded stretches After the arm of type monteggia fracture passes through manipulative reduction, front plate is used to abut with the front of the front of upper arm and forearm, rear to press from both sides For abutting with the back side at the back side of upper arm and forearm, inside clamping plate is used for and the medial surface of upper arm and the inside of forearm plate Face abuts, and outside clamping plate with the lateral surface of the lateral surface of upper arm and forearm for abutting；Front plate, rear plate, inside clamping plate And outside clamping plate is connected and fixed by fixation kit.

Arm is fixed in the outer strap used in above patent document, use environment by larger limitation, Due to the special shape structure of ankle, it is not easy to be used at ankle.

Summary of the invention
