Description
Technical field
This utility model relates to medical science orthopedic instrument technical field, specifically a kind of skull traction bow.
Background technology
The general unstability damage at cervical vertebra on clinical medicine is the skull traction device that adopts mostly.Such as cervical vertebra compression fracture or subluxation of cervical vertebra, be difficult to reach the purpose that resets, the generation of dislocation situation is very frequent, even can increase the weight of the state of an illness, keep the certain posture of head and neck and adopt the traction method that is fit to.The skull staple of general skull traction bow all is fixedly installed on the bow arm, in clinical use, usually be on skull, to hole earlier, could place skull tractor, such one is that the use of traction apparatus is very restricted, usually needs the cooperation of bone drill, and two are to use the bone drill can be to bringing very big wound on the patients ' psychological, the mental emotion even the state of an illness that have a strong impact on the patient all can increase the weight of, and bring a lot of inconvenience so for clinical traction.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of skull traction bow is provided.
The technical solution of the utility model realizes in the following manner, this skull traction bow, comprise that two identical bow arm middle parts are hinged by bearing pin, its structure is that two bow arm front ends respectively offer screwed hole, be rotary with the threaded post of band clamp nut on the screwed hole, threaded post is provided with the external screw thread that matches with the screwed hole female thread, threaded post post tip is the pin type, wherein an end and screw rod one end that bends arm is hinged for two bow arms, the end of another bow arm is hinged with the adjustment nut, adjusts nut and is screwed on the screw rod.
The bow arm is set to arc, and two bow arm opening subtended angles form a minor arc.
The bearing pin of two bow arms is provided with guiding piece, offers towing pad on the guiding piece.
The beneficial effect that this utility model is compared with prior art produced is:
This skull traction bow belongs to little bow, two bow arms are shorter, so minor arc of two bow arm opening subtended angle formation is tilted by the direction of the skull staple that pin type threaded post constitutes, the boring position is in calvarium center line both sides, be on the boss parietal, this place's skull is thicker, is difficult for penetrating inner table of skull, the bow arm is positioned at calvarium, does not influence the activity of position, patient side.Skull staple by pin type threaded post constitutes is used to thrust scalp and lamina externa cranii, and is simple to operate, even do not need sometimes to cut scalp and hole on skull, adjust the position after, directly will screw in and get final product with the threaded post of clamp nut.Bearing pin is provided with guiding piece, offers towing pad on the guiding piece, the convenient pull rope that connects of towing pad.This skull traction is simple in structure, and easy to operate practicality brings great convenience for the orthopaedics medical personnel, helps increasing work efficiency and therapeutic effect.
