Abstract
The utility model relates to a restoring fixing frame for double ankle dislocation and fracture, belonging to a non-operative instrument for dentofacial surgery. A size regulating metal head loop, a balance connecting rod and a balance rod forms a fixing basic frame for towing the restoration of the ankle dislocation; a towing top post for the ankle dislocation is connected with the top post with screws and is positioned on a towing arm which is connected with a towing arm shaft fixed on the metal head loop; the outer end of a towing shaft is provided with a locking screw cap, an elastic band is hung on a top post screw and the balance rod and the top post reaches the connection of the position needed for restoring the ankle dislocation by regulating the top post screw and the towing arm.
Description
The invention belongs to the non-operating theater instruments of decorative sursery.
The at present operative treatments that adopt of the prominent dislocation fracture of two condyles comprise the open reduction internal fixation and extract methods such as condyle is prominent more.Operative treatment diminishes nervus facialis, and operating field exposes insufficient, the internal fixation difficulty.Prominent back occlusal disturbance and the operation wound extractd of two condyles, the chance of increase ankylosis etc. may.
The purpose of this utility model provides the prominent dislocated fracture of a kind of pair of condyle fixed mount that resets, and can avoid the deficiency of operative treatment, by the means of the prominent fore-set of two condyles by elastic traction, can make displacement or the dislocation condyle is prominent resets, and the section of reaching disconnecting is touched, the purpose of clinical healing.
Accompanying drawing is the vertical section structural map of this utility model embodiment.When using the prominent dislocated fracture of condyle to reset fixed mount, at first need and to put 3～4 thick silicone rubber jaw pads between patient's bilateral distomolar, last lower jaw hook strip Arch bar splint intermaxillary elastic traction makes lower jaw recover positive occluding relation, then according to patient's head size adjustment ferrule circle (1), ferrule circle (1) is worn over patient's head (volume pillow level), the position of levelling condyle prominent traction fore-set (6) under x-ray fluoroscopy, be located at the prominent broken ends of fractured bone the place ahead of condyle, screw traction fore-set screw (7) promote traction fore-set (6) to greatest extent with the prominent leading edge generation mediate contact of condyle, elastic band (9) is hung in the traction fore-set screw (7) and the gimbal lever (3), making (7) drive draft arm (5) by elastic band elastic shrinkage tractive traction fore-set screw (7) rotates along draft arm movable axis (4), move in the glenoid fossa when the dislocation condyle is prominent, tighten locking nut (8) when fracture site produces contact, both can reach the prominent fixing purpose that resets of condyle.
The present invention is with external force size, direction and application point as required, promotes by the adjustable fore-set in position that condyle is prominent to be resetted in glenoid fossa, through suitable when resetting fixedly backward, cure the condyle dislocation fracture of dashing forward.
The medical device of realizing this invention is called the prominent dislocated fracture of the condyle fixing medical device (hereinafter to be referred as medical device) that resets.Its basic structure is as shown in drawings: with the ferrule circle (1) of an adjustable size, the balance connecting rod (2) and the gimbal lever (3) constitute the prominent reduction by traction stationary base mount of condyle, condyle prominent traction fore-set (6) connects for revolute with fore-set screw (7), it is located on the draft arm (5) jointly, draft arm (5) connects for revolute with traction arm axle (4) on the fixing metal head circle (1), when draft arm (5) rotates along traction arm axle (4), the traction fore-set is that same curve moves, and axis of traction (4) outer end is furnished with locking nut (8).Elastic band (9) hangs in the fore-set screw (7) and the gimbal lever (3), the pull strength that resets in order to generation, fore-set (6) can reach the prominent desired position that resets of condyle by reconciling joint fore-set screw (7) and draft arm (5), select the elastic band (9) of different elastic force can obtain the pull strength that resets that needs, when needs fixedly the time, tighten locking nut (8) and get final product.
The prominent dislocated fracture of the above-mentioned condyle fixing medical device that resets uses at clinical success.
Claims (3)
1, the prominent dislocated fracture of the two condyles fixed mount that resets is characterized in that: with a ferrule circle (1), and balance connecting rod (2) and the gimbal lever (3) the formation condyle reduction by traction stationary base mount of dashing forward.
2, according to the prominent dislocated fracture of described pair of condyle of claim 1 fixed mount that resets, it is characterized in that: condyle prominent traction fore-set (6) and fore-set Luo silk (7) be for revolute connects, and draft arm (5) connects for revolute with traction arm axle (4) on the fixing metal head circle (1).
3, according to claim 1 and the prominent dislocated fractures of the 2 described pairs of condyles fixed mount that resets, it is characterized in that: draft arm (5) is during along traction arm axle (4) rotation, and the traction fore-set is that same curve moves.
