Description
Technical field
Be mainly concerned with the fixture of the postoperative employing balloon tamponade of knee prosthesis, belong to technical field of medical instruments.
Background technology
TKA has developed gradually and maturation is applied to clinical, and at present, the patient that knee replacements is carried out in the whole world every year just reaches more than 60 ten thousand people.Medical patient mostly is the middle-aged and elderly people of long-term pathologic changes of knee joint, preoperative knee joint is because disease is often in flexing shape, postoperative due to wound pain knee joint also easy flexing, this situation is not if corrected, easily there is flexion contracture in suffering limb knee joint, affect the range of activity of suffering limb, therefore postoperative requirement is not when patient carries out functional exercise, should keep kneed and stretch position; The hemorrhage swelling of postoperative ankle is also knee replacements common complication, and have research display, the postoperative need for transfusion of knee prosthesis reaches 44%, and minimizing postoperative ankle is hemorrhage, swelling, can promote the rehabilitation of patient greatly; Meanwhile, lie in bed between convalescent period patient, guarantee suffering limb functional position is an important nursing requirement equally.
For above problem, normal nursing care mode in the following ways clinically at present: 1, for the problem preventing knee sprung contracture, often adopts postoperative mode of placing sandbag that weight do not wait, knee joint brace, plaster fixing in suffering limb knee joint; 2, for reducing, postoperative ankle is hemorrhage, the problem of swelling, now adopts ice bag cold compress in postoperative 24 hours clinically, has patent research to use cold compress and compressing conbined usage; 3, for the problem ensureing suffering limb functional position, around general employing suffering limb, placing articles maintains functional position, or relies on nurse often to remind patient oneself to carry out ankle flexion and extension maintenance functional position, the existing various types of T-shaped shoes also having sale on the market.Be with the weak point of upper type: wherein knee joint brace and plaster fixing, complex operation, acts on single, patient economy burden weight, and the reusable rate of apparatus is low; Knee joint brace compared by sandbag and Gypsum Fibrosum effect is slightly wide, rely on action of gravity to play compressing knee joint on the one hand and stretch effect, the effect of hemostasis by compression can be played on the other hand, but sandbag pressing knee joint, easy landing, not easily fix, the action of gravity that what simultaneously sandbag relied on is vertically downward, therefore sandbag is extremely uneven for the pressure of above knee joint and side; And knee joint pressure cannot be measured, assess; Be very effective in cold compress 24 hours after surgery, but unsuitable life-time service; Around suffering limb, stacked items affects the clean and tidy of bed unit undoubtedly; Rely on nurse to remind patient to maintain suffering limb functional position, both added the workload of nurse, too increased the psychological burden of patient simultaneously; The invention of T-shaped shoes is the progressive instrument maintaining suffering limb functional position, but it also has weak point, and common T-shaped shoes hinders the ankle flexion and extension after operation in patients.
Summary of the invention
In order to solve the problem of prior art, the utility model proposes a kind of knee replacements rear gasbag compressing fixture, the air bag that this device meets knee joint physiology profile by planform is oppressed knee joint, ensure that air bag contacts with knee joint closely, and employing balloon tamponade, ensure that air bag is to knee joint each pressurized position pressure uniform; Pressure gauge can show knee joint pressure size at any time; Foot holder can keep the functional position of foot, can ensure that knee joint left rotation and right rotation does not occur simultaneously, also can not affect the flexion and extension of patient's ankle.Compressing is stretched by this device, oppress auxiliary and keep the three kinds of effects of suffering limb functional position to gather in one.
