Description

Wicresoft's positor

Technical field

This utility model relates to the orthopedic medical device field, relates in particular to Wicresoft's positor that a kind of skeleton of breaking part for the sufferer extremity is done the traction that laterally resets.

Background technology

In orthopaedics class operation, when the breaking part skeleton of sufferer injured limbs is carried out to operative treatment, need first the traction that resets of breaking part skeleton, next step operation provides good precondition in order to perform the operation.At present when the breaking part skeleton is performed the operation, at first need manpower to pull the breaking part skeleton to do radial motion, under artificial draw, the doctor uses scalpel on the skin histology of the outside of breaking part skeleton, to cut a large openning, and then hook is extend on the skeleton that needs lateral traction, by hook, prize skeleton, skeleton is carried out to lateral traction, make the alignment of breaking part skeleton, then use exterior fixation bracket or internal fixation plate that the skeleton of alignment is fixed, wraps up, make breaking part skeleton energy normal growth, healing.

The shortcoming of above-mentioned traditional surgical approaches is: one, in operation process, need to someone prize the skeleton traction that laterally resets, and hook must be maintained to the position after prizing always, until the docking of breaking part skeleton is fixed, labor intensive so not only, and, because always there is unstability in manually-operated, brought inconvenience and unsafe factor for doctor's operation technique; Two, in operation process, no matter be use exterior fixation bracket or use internal fixation plate, all need on the skin histology of the outside of breaking part skeleton, cut a large openning, increase patient's wound area.
