Description
Technical field
The present invention relates to orthopedic medical device field, particularly relate to Wicresoft's positor that a kind of breaking part skeleton for patient limb does the traction that laterally resets.
Background technology
In the operation of orthopaedics class, when carrying out operative treatment to the breaking part skeleton of sufferer injured limbs, need first to carry out reset traction to breaking part skeleton, in order to perform the operation, next step operation provides good precondition.At present when performing the operation to breaking part skeleton, first manpower is needed to pull breaking part skeleton to do radial motion, under artificial draw, doctor uses scalpel to cut a large openning at the lateral cutaneous tissue of breaking part skeleton, and then hook extend into need on the skeleton of lateral traction, skeleton is prized by hook, lateral traction is carried out to skeleton, breaking part skeleton is alignd, then use exterior fixation bracket or internal fixation plate that the skeleton of alignment is fixed, is wrapped up, make breaking part skeleton energy normal growth, healing.
The shortcoming of above-mentioned traditional surgical approaches is: one, in operation process, need people to prize skeleton and carry out transverse direction and to reset traction, and hook must be maintained always the position after prizing, till the docking of breaking part skeleton is fixed, so not only labor intensive, and always there is unstability due to manual operation, bring inconvenience and unsafe factor to the operation technique of doctor; Two, in operation process, no matter be use exterior fixation bracket or use internal fixation plate, all need to cut a large openning at the lateral cutaneous tissue of breaking part skeleton, add the wound area of patient.
Summary of the invention
The technical problem of solution required for the present invention is: provide a kind of operation process of doctor that can make more convenient safer, and greatly can reduce Wicresoft's positor of wound area when using exterior fixation bracket.
For solving the problem, the technical solution used in the present invention is: described Wicresoft's positor, comprise fixed block, laterally the upper through hole and lower through-hole that are parallel to each other is offered in fixed block, fixed block top offers the first screwed hole, first screwed hole communicates with upper through hole, the first fixing bolt is housed in the first screwed hole, the bar handle of drag hook passes upper through hole and stretches out, the bar handle of drag hook is semicircle step shape, first bolt can be locked mutually with the upper plane of the semicircle step bars handle of drag hook, thus drag hook is fixed in fixed block, handle is fixed on the tail end of drag hook bar handle, adjusting screw(rod) passes lower through-hole and stretches out, and be positioned on the adjusting screw(rod) outside fixed block and be rotary with left nut and right nut respectively, adjusting screw(rod) can be axially fixed in fixed block by left and right nut, and parietal bone backshank end is connected with adjusting screw(rod) end by adapter sleeve.
Further, aforesaid Wicresoft positor, wherein, the end face of parietal bone needle section is provided with anti-skidding groove.
Further, aforesaid Wicresoft positor, wherein, handle end offers the semicircle stepped hole matched with the bar handle of drag hook, semicircle stepped hole upper end offers the second screwed hole, and the second screwed hole communicates with semicircle stepped hole, and handle is installed on the bar handle tail end of drag hook by semicircle stepped hole, the second fixing bolt is housed in the second screwed hole, and handle can be fixedly connected on the bar handle of drag hook by the second bolt.
Further, aforesaid Wicresoft positor, wherein, bow type block is provided with between drag hook and parietal bone pin, drag hook is positioned at bow type block upper groove, parietal bone pin is positioned at bow type block low groove, the 3rd screwed hole is provided with at upper groove top, the 4th screwed hole is provided with bottom low groove, the 3rd bolt of fixing drag hook is provided with in the 3rd screwed hole, the 4th bolt of fixing parietal bone pin is provided with in the 4th screwed hole, drag hook and parietal bone pin are fixed on the upper of bow type block by the 3rd bolt and the 4th bolt respectively, in low groove, make drag hook and parietal bone pin mutually shifting phenomena can not occur.
The invention has the beneficial effects as follows: the Wicresoft's positor using said structure, can simplify the operation, make operation process safer, more stable, efficiency is also higher; In addition, when adopting exterior fixation bracket to fix breaking part skeleton, only needing to cut very little wound at the lateral cutaneous tissue of breaking part skeleton, can drag hook be stretched into, substantially reduce wound area, also significantly reduce the pain of patient.
