Abstract
The utility model discloses a bone nail retractor, and relates to the technical field of medical instruments. The bone nail retractor consists of a sleeve, a slider, a screw, a rocker, a fixed rod, a moving rod and bone nail sleeves, and is characterized in that the slider matched with an inner cavity of the square sleeve is slidably sleeved in the square sleeve, the screw is in threaded connection in a center hole at the bottom of the sleeve, the outer end of the screw is connected with the rocker, and the inner end of the screw is fixedly connected with an inner bearing bush fixed on a right end face of the slider. The fixed rod is fixedly connected to the wall of the lower side of the right end of the sleeve, the upper end of the moving rod corresponding to the fixed rod penetrates through an axial through hole on the wall of the lower side of the sleeve to be further connected with a lower end face of the slider fixedly, and hinged balls which are connected with the bone nail sleeves are respectively fixed in spherical grooves on the lower end faces of the fixed rod and the moving rods through fastening bolts. When used for bone retraction or drawing, the bone nail retractor is convenient and easy to operate, is time-saving and labor-saving, and is particularly applicable to retraction of two bone nails with axes on different planes since the action distance of the bone nail retractor can be controlled accurately.
Description
Technical field: this utility model relates to technical field of medical instruments, specifically a kind of Retractors of bone nail.
Background technology: all be to pull open by dislocation double or that many humans manpower will be fractured to reset in fracture fixing operation, this sample loading mode wastes time and energy, but also increases misery to the patient, even also can meet accident in operation in the past again; 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 that nail is squeezed into a little also has quite high requirement.Implementing that skeleton retracts or during tractive, for axially not being difficult to finish with existing skeleton spreading forceps or reduction forceps at conplane nail.If use by force, in case operate inaccurate then can cause unexpected injury to the patient; And the operation technique of skeleton requires very high, and general spreading forceps or reduction forceps can accurately not controlled its operating distance.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and is implementing that skeleton retracts or during tractive, and is easy and simple to handle, time saving and energy saving, can accurately control the Retractors of bone nail of its operating distance.
The purpose of this utility model is achieved in that this Retractors of bone nail is comprised of sleeve, slide block, screw rod, crank, fixed bar, carriage release lever, nail sleeve pipe, slide in the square sleeve and be set with the slide block that adapts with its inner chamber, the interior screw rod outer end of centre bore is connected with crank at the bottom of being threaded in the sleeve cylinder, and inner bearing inner sleeve with being fixed on the slide block right side is fixedly linked; Be connected and fixed fixed bar on the sleeve right-hand member downside tube wall, be fixedly linked with the slide block lower surface after passing the axially extending bore above the sleeve downside tube wall on the carriage release lever corresponding with fixed bar, be connected with the hinged ball of nail sleeve pipe above being fixed wtih by fastening bolt respectively in the ball recess of fixed bar and carriage release lever lower surface.
The utility model has the advantages that: implementing that skeleton retracts or during tractive, easy and simple to handle, time saving and energy saving, can accurately control its operating distance, be particularly useful for retracting of two nails of axis on antarafacial.
Description of drawings: accompanying drawing 1 is structure cutaway view of the present utility model.
The specific embodiment: be described in further detail below in conjunction with 1 pair of this utility model of accompanying drawing: this Retractors of bone nail is comprised of sleeve 1, slide block 2, screw rod 3, crank 4, fixed bar 5, carriage release lever 6, nail sleeve pipe 7, square sleeve 1 interior slip is being set with the slide block 2 that adapts with its inner chamber, be threaded in that screw rod 3 outer ends in the centre bore are connected with crank 4 at the bottom of 1 in the sleeve, inner bearing 8 inner sleeves with being fixed on slide block 2 right sides are fixedly linked; Be connected and fixed fixed bar 5 on the sleeve 1 right-hand member downside tube wall, carriage release lever 6 upper ends corresponding with fixed bar 5 are fixedly linked with slide block 2 lower surfaces after passing axially extending bore above the sleeve 1 downside tube wall, are connected with the hinged ball 9 of nail sleeve pipe 7 above being fixed wtih by fastening bolt respectively in the ball recess of fixed bar 5 and carriage release lever 6 lower surfaces.
