Description

Femoral tuberosity part lateral traction frame
Technical Field
The utility model relates to the technical field of medical equipment, more specifically say, relate to a but reuse, the traction frame of thighbone tuberosity portion side that multi-angle was pull.
Background
Unstable fracture of pelvis and acetabulum is high-energy injury, most men are usually suffered from injuries such as car accidents, high falling, collapse, crushing and smashing and the like, and other important organ injuries such as head, chest, abdomen, particularly pelvic organ injuries are combined to cause heavy bleeding or shock, and the death rate is up to 10.2%. The reported mortality rate in national records and the like is even as high as 20-50%. The occurrence of pelvic fractures in the elderly means critical conditions, with mortality rates of even 37% in patients older than 60 years of age. The report of the 2005 application of meta analysis by Giannoudis PV et al: the displacement type of the acetabulum fracture depends on the relationship between the femoral head and the acetabulum at the moment of injury, and the reason of the acetabulum fracture is as follows: traffic injury 80.5%, high fall injury 10.7%, other reasons: 8.8 percent. 20 to 50 percent of other organ injuries are combined, and 36 percent of the injuries are combined with lower limb fractures.
Pelvic and acetabular fractures are mostly caused by high-energy trauma, and are mostly combined with craniocerebral trauma, lung contusion, abdominal organ injury, great bleeding amount, unstable illness after injury and other factors, the death rate is up to 10.2%, and meanwhile, as the life of a patient is rescued, the treatment of pelvic and acetabular fractures is delayed, and the disability rate is often up to 50%. How to optimally treat the fracture of the pelvis and the acetabulum while rescuing the life of a patient at the first time and reduce the further damage of the patient caused by the secondary striking of the fracture operation at the later stage is always the key point and the difficulty of traumatic orthopedics. Therefore, how to effectively solve the problem of displacement and fixation of pelvis and acetabulum fracture in the perioperative period is a difficult task faced by clinical workers.
In recent years, with the progress of fundamental and clinical studies on pelvic injuries and understanding of injury mechanisms thereof, diagnosis and treatment of dislocation of fracture between pelvis and acetabulum have been greatly advanced. Although the mortality rate of pelvic fractures has been reduced to 5% to 20%, its long-term efficacy has not been satisfactory.
Several documents have agreed to propose: the unstable pelvis and acetabulum fracture displacement is guided by a DCO (Damage con ortho-surgery) to clinical staged treatment, firstly antishock treatment and combined injury treatment are carried out, and the life is saved as much as possible; ICU resuscitation is carried out in the second stage; and in the third stage, after vital signs are stabilized, performing operative treatment on the fracture of the pelvis and the acetabulum. The early temporary use of the external fixing bracket can fix the pelvic ring in a short time, reduce the bleeding of the fracture surface and reduce and keep the pelvic volume constant, thereby effectively exerting the filling effect of the pelvis and achieving the purpose of controlling the bleeding. Meanwhile, the large-weight continuous bone traction on the affected femoral condyle and the traction reduction of the femoral tuberosity side square bone are applied, and the pelvis and acetabulum fracture displacement is preliminarily stabilized.
The literature reports that the fracture of the pelvis and the acetabulum is mostly influenced by the impact of the femoral head to move upwards, the bone traction on the femoral condyle is matched with the lateral traction of the femoral tuberosity in the early period before operation, and the fracture fragments on the inner wall of the acetabulum can recover the anatomical structure of the acetabulum to the maximum degree under the combined action of pelvic floor fascia, abdominal pressure, intra-articular negative pressure and traction of a joint capsule, so that more satisfactory reduction can be achieved. Can be minimally invasive and percutaneous fixed or simplify the difficulty of the incision reduction operation in the operation, reduce the wound of the patient in the operation, and particularly lead the patient to be combined with multiple wounds and emergency patients. If the treatment is carried out for more than 1 week or later, due to organization of hematoma, fibrous adhesion, traumatic inflammation change of tissues and the like can influence and hinder reduction of fracture blocks of pelvis and acetabulum, and a new idea is provided for further discussing the effects of applying three-dimensional bone traction reduction in the perioperative period and preliminarily stabilizing fracture of pelvis and acetabulum.
Based on the above recognition and earlier stage research, the utility model discloses mainly follow the design of thighbone tuberosity side traction frame and jointly vertically pull on the thighbone condyle and value aassessment in pelvis and acetabular fracture dislocation treatment. At present, the femoral side traction method, the traction vector angle and the traction weight are various, and no fixed and repeatedly-applicable femoral side traction medical instrument is available according to personal clinical experience and hospital temporary equipment. Therefore, the utility model designs the femoral tuberosity side traction frame which can be repeatedly used and can be dragged by multiple angles with the clinical research object of the patient with pelvis and acetabulum fracture dislocation.

Perioperative femoral supracondylar bone traction is a reliable pelvis reduction method, and is particularly suitable for emergency patients. Can replace the pelvis external fixation frame or the posterior ring C-shaped clamp at some times.
The presrag Grubor et al scholars obtain satisfactory curative effects on acetabular fracture dislocation by using the combination of femoral condylar bone traction and femoral tuberosity side traction. The results of 14 patients showed: in 8 cases (57%), satisfactorily 4 (28%), and generally 2 cases (15%).
