Abstract
The utility model relates to a universal dilating and repositioning device for a bone fracture, which can adjust the length of a telescopic joint screw. The utility model comprises the telescopic joint screw and a two-section reverse extending sleeve barrel for an inner screw hole. The utility model is characterized in that both ends of the two-section reverse extending sleeve barrel for an inner screw hole are connected with the telescopic joint screw, and the middle position is provided with a jack where a bolt is inserted; the extending sleeve barrel rotates to make the telescopic joint screw extended or shortened; one end of the telescopic joint screw is provided with a connecting block with an inner screw hole; a tapping screw which is connected with the connecting block can be adjusted up and down,; the end of the telescopic joint screw, which is connected with a ball head of a universal joint, can rotate randomly. The universal joint of the utility model can rotate randomly to correct angle deformity, and the bone fixation of the tapping screw for fixing bones can lift and pull the bone fracture laterally or can push, press and correct shifting deformity. The universal joint after being locked can make the bone fracture stable casually, which is favorable to placing a steel plate which crosses over the end of the bone fracture to make the effective reposition and fixation for the bone fracture in a non touching state. The utility model is favorable to the union of the bone fracture.
Description
Technical field
The present invention relates to medical apparatus and instruments, refer to a kind of universal fracture distraction reduction device that surgical clinical work is used comminuted fracture that is used for especially.
Background technology
In clinical position,,, be difficult to reset owing to the muscle traction makes the ready-made angle of fracturing, cripetura, rotation and displacement deformity to comminuted fracture.The extensively accompanying soft tissue of cleavage fracture piece that resets, it is serious to cause fracture blood fortune to be destroyed, and is difficult to healing and forms bone does not connect.Even reset reluctantly, often when placing internal fixation steel plate, need unclamp clamper and make loss of reposition.
Existing like instrument weak point is fixed as bone with smooth steinman pin, can only strut the rectification cripetura, can not correct into the angle, rotation and displacement deformity.Hard this type of odd-shaped rectification of resistance on the contrary.
Summary of the invention
The purpose of this utility model is to provide a kind of universal fracture distraction reduction device, only need a little to appear the far and near section of fracture, respectively squeeze into one piece of tapping screw, can rectify fracture effectively and put in order, needn't peel off fracture, only need under perspective, will fracture and reset substantially, with regard to the lockable universal joint, lay the steel plate internal fixation at leisure, can save operating time, minimizing reduces the probability of bone does not connect to the destruction of fracture soft tissue.Connect with universal joint and can rotate the rectification angulation deformity arbitrarily, with the tapping screw bone fixing the fracture side direction can be lifted or pushes correct the displacement deformity.
For reaching above-mentioned purpose, this utility model comprises flexible connecting screw rod, prolongs sleeve, is characterized in: one has the oppositely prolongation sleeve of inner bolt hole of two sections, and the one end is connected with a flexible connecting screw rod, and end also is connected with a flexible connecting screw rod in addition; The end of flexible connecting screw rod is connected with tapping screw.Described two section oppositely inner bolt hole prolongs sleeve, and there is a jack position in the middle of it.Described flexible connecting screw rod, the one end has external screw thread, and end is for having the inner bolt hole contiguous block in addition; One has the externally threaded tapping screw of two sections is connected with contiguous block.Described another flexible connecting screw rod, the one end has external screw thread, and end has an inner bolt hole for the universal joint spheroid on the universal joint spheroid in addition.The universal joint spheroid connects with the universal joint bulb, and an end of universal joint bulb is a ball, and end is for having the contiguous block of inner bolt hole in addition; One has the externally threaded tapping screw of two sections is connected with contiguous block.The rustless steel brill is attacked sheath and is sleeved on the tapping screw outside.
The utility model has the advantages that:
1, can rotate the rectification angulation deformity arbitrarily with the universal joint connection;
2, have the tapping screw bone of two section screw threads fixing the fracture side direction can be lifted or pushes correct the displacement deformity;
3, have the oppositely prolongation sleeve of inner bolt hole of two sections, can easily the fracture of stretching be strutted;
4, can provide the stable of fracture after the universal joint locking temporarily, be beneficial to and lay the steel plate of crossing over fracture end, fracture is carried out the active homing of " not contacting " and fixing, be beneficial to union of fracture.
