Description
Technical field
The invention belongs to technical field of medical instruments, particularly relate to a kind of disposable bone tractor.
Background technology
Bone traction is a kind of operation method for temporary fixed limbs of patient fracture site, is widely used in clinical.At present conventional bone traction operating theater instruments is bone tractor, is mainly made up of bone traction bow and fine steel needle two parts, and wherein bone traction bow can Reusability.When needs are implemented bone when operation traction, first opened the bone traction bag of the operating theater instruments such as the fine steel needle, bitbrace or the electric drill that all size are housed inside by doctor, then carry out sterilization, location.When operation, the fine steel needle of a suitable specification is screwed in to the anchor point near fracture site on limbs of patient with bitbrace or electric drill, until revolve bilateral cortical bone and pass from opposite side prick skin, then the two ends of fine steel needle are connected with bone traction bow, but, there is following point in the bone tractor of this prior art: because the length of fine steel needle is not mated with bone traction bow, therefore the postoperative length that usually needs to prune fine steel needle, but also needle point backshank need to be bent and wraps up needle point backshank, to prevent secondary damage, therefore cause operating time long, operating procedure is many.In addition, bone traction bow adopts metal material to make conventionally, therefore heavier, and Reusability easily produces aleopation, and existing bone tractor can not meet the needs of modern medical service development in a word.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of reasonable in design, safe and reliable disposable bone tractor.
In order to achieve the above object, disposable bone tractor provided by the invention comprises bone traction bow, fine steel needle, two fine steel needles fixing fixture block, multiple screw and T shape spanners; Wherein the bow top bit standoff distance of bone traction bow run through be formed with multiple for connecting the circular hole of pull rope, the local thickening in both sides bows foot position, and longitudinally run through and be formed with two screw fixed holes on thickening position; The fixing fixture block of fine steel needle is L-shaped, dual-side medial surface contacts respectively on the front end face and bottom surface of thickening position on bone traction bow, and with on the side that contacts of thickening bottom surface, position, be formed with two respectively with thickening position on two screws that screw fixed hole is corresponding, on this side medial surface, the position between two screws is formed with one for placing the semicircle orifice of fine steel needle along lateral recesses simultaneously; Fine steel needle is the smooth round needle of metal, and front end is cone, and tail end is multiedge cylinder, and two ends are separately positioned in two semicircle orifices on the fixing fixture block of two fine steel needles; Screw is interior hexagonal tack metallic screw, and each screw runs through and is arranged in screw fixed hole of bone traction bow and a screw of the fixing fixture block of fine steel needle, utilizes the fixing fixture block of bone traction bow and fine steel needle that fine steel needle is locked; The vertical rod outer end middle part of T shape spanner forms a many prismatics hole being used in conjunction with fine steel needle tail end multiedge cylinder, horizon bar one end is outside be with screw on the hexagonal prism that is used in conjunction with of inner hexagonal hole.
The length of described fine steel needle is less than or equal to the ultimate range between both sides bow foot on bone traction bow, is greater than the minimum range between both sides bow foot on bone traction bow simultaneously.
The diameter in the described fixing fixture block upper semi-circle of fine steel needle hole is identical with the diameter of fine steel needle,
The fixing fixture block of described bone traction bow and fine steel needle all adopts food grade plastic material to make.
Disposable bone tractor provided by the invention can be simplified operation method; Abolish heavy operation and revolved tool; Bone traction bow and fine steel needle support the use, and the length of fine steel needle is less than or equal to the width of traction bow, can not produce secondary damage; Bone tractor major part is plastic material, and quality is light, and therefore material gentleness can improve patient's psychological feelings; Disposable medical instrument can reduce aleopation in hospital, meets modern medical service technical requirement.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, disposable bone tractor provided by the invention is elaborated.
As shown in Fig. 1～Fig. 8, disposable bone tractor provided by the invention comprises bone traction bow 1, fine steel needle 2, two fine steel needles fixing fixture block 3, multiple screw 4 and T shape spanners 5; Wherein the bow top bit standoff distance of bone traction bow 1 run through be formed with multiple for connecting the circular hole 6 of pull rope, the local thickening in both sides bows foot position, and longitudinally run through and be formed with two screw fixed holes 7 on thickening position; The fixing fixture block 3 of fine steel needle is L-shaped, dual-side medial surface contacts respectively on the front end face and bottom surface of thickening position on bone traction bow 1, and with on the side that contacts of thickening bottom surface, position, be formed with two respectively with thickening position on two screws 9 that screw fixed hole 7 is corresponding, on this side medial surface, the position between two screws 9 is formed with one for placing the semicircle orifice 10 of fine steel needle 2 along lateral recesses simultaneously; Fine steel needle 2 is the smooth round needle of metal, and front end is cone, and tail end is multiedge cylinder, and two ends are separately positioned in two semicircle orifices 10 on the fixing fixture block 3 of two fine steel needles; Screw 4 is interior hexagonal tack metallic screw, and each screw 4 runs through and is arranged in screw fixed hole 7 of bone traction bow 1 and a screw 9 of the fixing fixture block 3 of fine steel needle, utilizes the fixing fixture block 3 of bone traction bow 1 and fine steel needle that fine steel needle 2 is locked; The vertical rod outer end middle part of T shape spanner 5 forms a many prismatics hole 11 being used in conjunction with fine steel needle 2 tail end multiedge cylinders, horizon bar one end is outside be with screw 4 on the hexagonal prism 12 that is used in conjunction with of inner hexagonal hole.
