Abstract
The utility model provides a bone screw retractor which belongs to the technical field of the medical device; the bone screw retractor comprises a screw, a retractor piece, a positioning piece and a bone nail sleeve; the retractor piece is provided with a thread screw hole which matches with the screw; the retractor piece is connected with the screw thread; the screw is provided with two stop projections; the positioning piece is arranged between two stop projections and connected with the screw by an axis hinge; one end of the bone nail sleeve is provided with a hinge ball; the retractor piece and the positioning piece are respectively connected with a bone nail sleeve ball hinge; the retractor piece and the positioning piece are respectively provided with a hinge ball fixed screw which passes through the retractor piece and the positioning piece and is then connected with the top end of the hinge ball; and one end of the screw is provided with a rotating handle. The utility model has simple structure and easy use, can realize the retracting action of the bone nail along two opposite directions by the rotation along the positive and negative directions of the rotating handle, is especially applied to the retracting of two bone nails of which the axes are on a different surface, saves time and manpower, and is practically used in the retracting and reset operation of the fracture.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of nail retractor.
Background technology
The hardness of skeleton and its tenacity can be imagined.Aspect orthopaedics, the treatment or the difficulty of operation for skeleton are also quite high, all be to draw back again by dislocation double or that many humans manpower will be fractured to reset in the fracture fixation operation in the past, this sample loading mode wastes time and energy very much, but also increases misery even also can meet accident in operation to the patient; The medical skill of present stage is generally all assisted complete operation by some operating theater instruments at orthopaedics, especially adopts resetting that nail comes that interoperation fractures.But the selection of squeezing into a little of nail also has quite high requirement.Implementing that skeleton retracts or during tractive, for axially not being difficult to finish with the skeleton spreading forceps or the reduction forceps of prior art at conplane nail.If use by force, in case operate inaccurate then can cause unexpected injury to the patient, the operation technique of relevant skeleton requires very high, and general spreading forceps or reduction forceps can not accurately be controlled the distance of its action.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of nail retractor is provided.
The technical solution of the utility model realizes in the following manner, the nail retractor, comprise screw rod, retract part, keeper and nail sleeve pipe, retracting part has and the match screw of screw thread of screw rod, retracting part is connected with screw flight, screw rod is provided with two spacing block sets, and keeper is arranged between two spacing block sets and adopts axle to be hinged with screw rod; Nail sleeve pipe one end is provided with hinged ball, retracts part and is connected with nail sleeve pipe ball pivot respectively with keeper, retracts and is rotary with hinged ball fixed screw on part and the keeper, and hinged ball fixed screw passes and retracts part and keeper and hinged ball apical grafting; Screw rod one end is provided with rotating handles.
The utility model has the advantages that:
This nail retractor is simple in structure, easy to use, utilize the rotation of the both forward and reverse directions of rotating handles just can realize that two of nails are rightabout and retract action, be particularly useful for retracting of two nails of axis on antarafacial, time saving and energy saving, be useful for retracting and reset operation of fracture.
