Abstract
This utility model belongs to medical instruments field, a kind of fixer for repositioner of medical malbeolus fracture, be provided with two hook-shaped fixed teeth (1), pressure rod (2), hold-down screw (3) and compression module (4) composition, it is characterized in that loosening or the direction of fastening adjustment nut (6) scalable or stable fixed teeth (1) makes the size of its applicable sclerite, hold-down screw (3) is fixed in tibia sclerotin, fixed teeth (1) is driven to produce pressurization fixation by the worm screw (5) in rotary presser module (4) by pressure rod (2), thus reach and drive fracture of medial malleolus block reset and time to fix, for the object that further firmly internal fixtion creates conditions, there is wound little, reset accurately, fixing reliable, the advantage such as easy and simple to handle.
Description
Technical field
This utility model belongs to medical instruments field, relate in Orthopedic Clinical and having fracture of medial malleolus block reset and the reduction fixture device fixedly secured, especially can drive medial ankle bone folded block parking position accuracy and the reduction fixture device fixedly secured for orthopedist provides good in orthopaedics Minimally Invasive Surgery.
Background technology
When resetting to sclerite in bone surgery, the corresponding instrument of many needs is assisted, and the instrument needed in reseting procedure has multiple, and because fracture site is different, classification of fracture is different, need the mode of carrying out internal fixtion different, required instrument is varied.Fracture of medial malleolus often shows as less subtriangular sclerite, because its fracture is involved articular surface of ankle and is connected with deltoid ligament, the quality resetted directly has influence on the function of ankle joint, often adopt open reduction clinically, often utilizing towel clamp towel forceps to clamp sclerite in operation to carry out para-position and utilize towel clamp towel forceps two pointed tooths to stride across the pressurization of fracture line time fixing, creating conditions for fixedly securing further.When adopting closed reduction Wicresoft internal fixation operation, owing to not cutting skin, adopt during towel clamp towel forceps clamping and can be difficult to because of the stop of surrounding soft tissue carry out, clinical carry out manual reduction Wicresoft internal fixtion time, doctor often adopts first manual reduction, undertaken resetting by the mode that fine steel needle is fixing again and fix, but when driving draw point to fix with bone drill after manual reduction is accurate, often because maneuver drives the strength of sclerite rotation when wire drill enters sclerotin to the sclerite bed knife quantity not sufficient resetted resist and sclerite rotation displacement very easily occurs, sometimes pierce steel needle rotary drive sclerite rotation in process in order to avoid draw point and adopt the method directly draw point hammering being entered sclerotin to be fixed, but it is cracked often because medial ankle bone folded block is less, bone block to occur, cause resetting and fixing unsuccessfully.Adopt which kind of method parking position accuracy medial ankle bone folded block, and the temporary fixed sclerite resetted that can be more stable, provide condition to be that fracture of medial malleolus resets and a fixing difficult problem for fixedly securing further.
Summary of the invention
For solving above-mentioned technical deficiency, this utility model provides a kind of fixer for repositioner of medical malbeolus fracture, and this utensil controls rotation and the displacement of sclerite by dentalation and pressurize fixing, to realize in fracture of medial malleolus Minimally Invasive Surgery sclerite reset and temporary fixed.The technical scheme that the present invention solves is: a kind of fixer for repositioner of medical malbeolus fracture, be provided with two hook-shaped fixed teeth (1), pressure rod (2), hold-down screw (3) and compression module (4) composition, it is characterized in that loosening or the direction of fastening adjustment nut (6) scalable or stable fixed teeth (1) makes the size of its applicable sclerite, hold-down screw (3) is fixed in tibia sclerotin, fixed teeth (1) is driven to produce pressurization fixation by the worm screw (5) in rotary presser module (4) by pressure rod (2), thus reach and drive fracture of medial malleolus block reset and time to fix, for the object that further firmly internal fixtion creates conditions.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
This utility model is specifically described by example below in conjunction with accompanying drawing.
Detailed description of the invention
Fixer for repositioner of medical malbeolus fracture, be provided with two hook-shaped fixed teeth 1, pressure rod 2, hold-down screw 3 and compression modules 4 to form, it is characterized in that loosening or the direction of fastening adjustment nut 6 scalable or stable fixed teeth 1 makes the size of its applicable sclerite, hold-down screw 3 is fixed in tibia sclerotin, fixed teeth 1 is driven to produce pressurization fixation by the worm screw 5 in rotary presser module 4 by pressure rod 2, thus reach and drive fracture of medial malleolus block reset and time to fix, be the object that creates conditions of firm internal fixtion further.
This utility model controls medial ankle bone folded block rotation by dentalation is with displacement and pressurize and fix, realizing sclerite in fracture of medial malleolus Minimally Invasive Surgery resets with temporary fixed, create good condition for fixedly securing further, have wound little, reset accurately, the fixing advantage such as reliable, easy and simple to handle.
