Description
Technical field
The present invention relates to medical apparatus and instruments, the especially a kind of forearm radius far-end fracture of the clinical use of orthopaedics and manual, the adjustable traction apparatus that dislocation of shoulder is used, specifically a kind of radius far-end fracture reset and dislocation of shoulder traction apparatus of being suitable for.
Background technology
At present, along with the change of epoch and society, the sick and wounded spectrum of orthopaedics has had very big variation.Tuberculosis of bone and joint in the past, pyogenic infection, poliomyelitis etc. reduce now significantly, and the wound that takes place in the vehicle accident obviously rises.While is along with the aging of global population, the also corresponding increase of the fracture that causes on the senile osteoporosis basis.
Colles fracture, Smith fracture, chi distal radius double fracture etc. are one of modal fracture of human body, and pilosity is born in person in middle and old age, and the women is more than the male.Mostly be due to the indirect violence, it is due to the direct violence that the minority case is also arranged.Such treatment of fractures method mainly contains manual reduction external plaster fixation, open reduction internal fixation, support external fixation etc. at present.Adopt which kind of Therapeutic Method to need to decide according to concrete traumatic condition.The manual reduction external plaster fixation is the most classical also the most basic Therapeutic Method of orthopaedics.But we find that in clinical practice this technology is subjected to artificial factor very big.The effect that resets depends on patient's maneuver, skill, experience and assistants' cooperation to a great extent.Implementing manual reduction needs the doctor more than at least 2 to carry out simultaneously, the long countertraction of need going ahead of the rest, and also before Gypsum Fibrosum solidified after resetting, fracture still had the possibility of displacement.Though open reduction internal fixation definite effect, patient need bear certain misery, and needs second operation to take out inner matter.Exterior fixation bracket is a kind of Therapeutic Method that rises recently, and operation wound is smaller, and curative effect is sure, but expense is comparatively expensive, the possibility of pin track infection is arranged in addition, so still can not generally promote clinically at present.Therefore, the manual reduction external plaster fixation remains a kind of effective, economic, practical Therapeutic Method undoubtedly.But the special equipment that resets that lacks at present a kind of simple and definite effect clinically.
Dislocation of shoulder is modal in the big joint dislocation of whole body, has report to account for 45-50%.Fresh dislocation of shoulder Therapeutic Principle should be capable as early as possible closed manual reduction.Timely reduction of patient misery not only, and be easy to reset.Give appropriate anaesthetization before generally resetting.The maneuver that resets is divided into based on traction skill or serves as main two kinds with the lever method.Generally safer with traction skill.Utilize the lever maneuver that soft tissue injury and fracture more easily take place.
Traction method mainly contains Hippocratic reduced method and Stimson traction.Wherein the Hippocratic reduced method is Hippocrate, is the most ancient repositioning method, still is widely adopted so far.Only need a people to operate.But in implementation process, the possibility of neural blood vessel damage is arranged.In addition, those osteoporotic elderly patients particularly, in the process that resets, still have and very big may cause iatrogenic fracture, if iatrogenic fracture takes place, successive treatment art formula complexity then, and should go the shoulder joint displacement in most cases, operating difficulty is big, generally need to implement at tertiary hospitals, expense is high in addition, therefore usually causes doctor-patient dispute.Stimson traction is more comparatively safe, and it is a kind of safe, effective, repositioning method of waiting at ease for an exhausted opponent that this method is known from experience in practice.Advantage is not need anesthesia promptly practicable.But require the patient to get the ventricumbent position, influence cardio-pulmonary function, be not suitable for old, weak patient and use, also lack a kind of method that hangs the traction weight of well fixing at present in the process of traction, general at present employing rope or binder hang on the wrist place with weight.But prolonged traction, the compressing of wrist place rope have the possibility that causes the nervus vasculairs damage, and patient has uncomfortable main suit in distraction procedure.
