Description
Technical field
This utility model relates to technical field of medical instruments, especially relates to a kind of T-shaped percutaneous prying and pulling device.
Background technology
In Orthopedic Clinical, fractures principle is reset, fixing, functional training.Fix, just must have good reset, fracture not reset is just far from being fixing, let alone functional training.Therefore, the reduction of the fracture is basis and the key of fractures.Have two kinds to the repositioning method of fracture in current orthopaedics, one be traditional closed manual reduction i.e. " bone-setting manipulation ", namely on body surface, execute art by maneuver, correct the fracture of displacement; Another kind of method is then open reduction, namely cuts skin, subcutaneous tissue, fascia layer, Musclar layer and arrive fracture area by certain Anatomicapproach, is resetted under direct-view by certain apparatus to fracture end.
But all there are some technological deficiencies in above-mentioned treatment obviously; Such as: closed manual reduction be according to fracture injured mechanism and displacement fracture situation, a kind of repositioning method that inverse damage mechanisms is corrected displacement fracture, the method must across soft tissue manipulation, strength is difficult to effectively arrive, usually in order to reach reset object, the soft tissue of fracture area being badly damaged, even occurring soft tissue complication as serious in pressure ulcer, osteofascial compartment syndrome etc.Open reduction is then a kind of repositioning method clearly having wound, successively must cut soft tissue and arrive fracture area, has iatrogenic destruction to fracture environment, usually causes the complication such as fracture region blood fortune is impaired, bone does not connect to occur because of resetting.
In recent years, along with the fast development of less invasive techniques in orthopaedics, fracture usually adopts Minimally Invasive Surgery to reach therapeutic purposes, but Wicresoft's internal fixtion also just can must carry out on the good basis resetted, and traditional method reduction is usually difficult to prove effective.A set of percutaneous that percutaneous implement reduction instrument produces just under this background, the reduction instrument of Wicresoft, say in a sense, apparatus is the extension of hands, apparatus resets the extension of namely manual reduction, utilize the repositioning method that this apparatus is implemented, be namely different from traditional whole bone maneuver, be also different from open reduction method, the reset issues before trauma fracture execution Wicresoft internal fixtion can be solved, again can in the drawback of evading above-mentioned two kinds of repositioning methods in varying degrees.
In concrete reset operation process, two fracture ends of how to make to have ruptured dislocation carry out being a puzzlement those skilled in the art's difficult problem to the opposite direction percutaneous reduction by leverage of dislocation.Therefore, how overcoming above-mentioned technological deficiency is those skilled in the art's problem demanding prompt solutions.
