Description
Technical field
This utility model belongs to medical instruments field, relate in Orthopedic Clinical the guiding holder that there is percutaneous reduction and guide accurately fixing fracture, especially percutaneous reduction deep in operation can be provided to fracture and the reduction of the fracture guiding screw accurately to fixedly secure guiding holder for orthopedist.
Background technology
In bone surgery, open reduction and closed reduction two kinds are broadly divided into the reset of fracture, open reduction can be looked at straight down the reduction of the fracture with fixing, operate comparatively simple, intuitive, it is the main method of the current reduction of the fracture, often need incision in a big way just can reach the requirement of performing the operation and appearing, even if no exception to less sclerite for the fracture relating to joint because structures surrounding joints is complicated.In recent years, many orthopedists attempt adopting multiple method to carry out closed reduction internal fixtion to dissimilar fracture, comprise reduction by traction, simple manual reduction, draw point percutaneous reduction by leverage etc., these repositioning methods can reach good reset effect sometimes, particularly draw point percutaneous reduction by leverage, good selection to the reset of fracture near the joint, but exist in clinical practice after sclerite resets and be difficult to maintain and fixing problem, in operating process after the normal generation reduction of the fracture accurately, in further fixation procedure because bone block does not have good temporary fixed and occur to be shifted again, particularly need to carry out that screw is fixing often needs first to carry out location drilling, be screwed into screw again, each link all may occur that sclerite rotates, displacement, often fix rear fracture and be unsatisfied with the phenomenon again adjusted, because fracture near the joint block mostly is spongy bone, and owing to being subject to bone block size, shape affects, the fixed area of sclerite the best may be little or unique, reselect fixing point after first time failure to be difficult to reach best fixed effect.
Summary of the invention
For solving above-mentioned technical deficiency, this utility model provides a kind of reduction of the fracture guiding holder, this utensil can move sclerite parking position accuracy and fixedly secures temporarily by belt, and by guider, screw is accurately imported best fixed area and fixedly secure, be conducive to the closed reduction of deep sclerite with fixing.The technical scheme that the present invention solves is: a kind of reduction of the fracture guiding holder, be provided with handle (1), jaw arm (2) and be connected to reset tooth (3) and the fixed teeth (4) of jaw arm (2) far-end, pilot sleeve (5) is connected with reset tooth (3), it is characterized in that fixed teeth (4) is butted on the offside of bone block as fulcrum, reset tooth (3) percutaneous inserts and is fixed on sclerite, and drive it to reset, reset accurately and two handles (1) are extruded in opposite directions, back-moving spring (6) is out of shape, sclerite is fixed by reset tooth (3), lock with securing rod (7), pilot sleeve (5) turns around reset tooth spiral selects best fixing point by fixing for screw importing, the object reaching sclerite percutaneous parking position accuracy and fixedly secure.
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
Reduction of the fracture guiding holder, be provided with handle 1, jaw arm 2 and the reset tooth 3 and the fixed teeth 4 that are connected to jaw arm 2 far-end, pilot sleeve 5 is connected with reset tooth 3, it is characterized in that fixed teeth 4 is butted on the offside of bone block as fulcrum, reset tooth 3 percutaneous inserts and is fixed on sclerite, and drive it to reset, reset accurately and two handles 1 are extruded in opposite directions, back-moving spring 6 is out of shape, sclerite is fixed by reset tooth 3, lock with securing rod 7, pilot sleeve 5 turns around reset tooth spiral selects best fixing point by fixing for screw importing, the object reaching sclerite percutaneous parking position accuracy and fixedly secure.
This utility model provides percutaneous parking position accuracy deep sclerite in bone surgery and imports the function that screw fixedly secures, and has that wound is little, easy, the internal fixtion of resetting imports point selection accurately and the fixing advantage such as reliable.
