Description

Technical Field

[0001] The utility model relates to the technical field related to medical instruments, in particular to an adaptive medical joint fixator. Background Art

[0002] Medical devices, also known as medical equipment, refer to instruments, equipment, appliances, materials or other items used on the human body alone or in combination, including the required software; their effects on the human body surface and body are not achieved by pharmacological, immunological or metabolic means, but these means may be involved and play a certain auxiliary role; when patients have knee joint tissue lesions and fractures and other conditions, they need to use medical devices such as knee fixators. Knee fixators play a role in fixing and supporting the patient's knee and preventing further lesions of the knee joint tissue. The effective support of the knee fixator to the knee joint is conducive to the healing of knee-related tissues.

[0003] In the existing knee joint fixator, the traditional plaster fixation method is replaced, making the joint fixation more lightweight and breathable. However, the knee joint fixator is not as stable as plaster and is not easy to fall off. When the knee joint is used in daily activities, the knee joint fixator is easy to slip if it is not tied tightly enough on the thigh. Therefore, there is a need to propose an adaptive medical joint fixator. Utility Model Content

[0011] Preferably, the sponge strips and the breathable net are connected by adhesive bonding, and the sponge strips are arranged parallel to each other.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. This kind of adaptive medical joint fixator is used in combination with a belt, a limit frame, a second limit hole, a locking plate, a pin and a pin. During the use of the device, the two ends of the belt are pulled until the belt is tightly fixed to a suitable position on the thigh, and then one end of the belt is inserted into the limit frame for fixing, and then the pin on the pin is rotated and buckled into the corresponding second limit hole to fix the locking plate. In this way, the calf support frame and the thigh support frame are more tightly fixed on the thigh through the belt to prevent the calf support frame and the thigh support frame from slipping. It is easy to operate and widely used in medical use, and allows patients to adjust their own behavior to adapt to the environment.

[0014] 2. This kind of adaptive medical joint fixator is used in coordination with threaded holes, bolts, a first fixing frame, a groove, a first limiting hole, a screw, a screw ring and a second fixing frame. During the use of the device, the bolts in the threaded holes in the sliding connecting plate drive the connecting plate to slide together with the calf support frame on the first fixing frame to adjust the positions of the calf support frame and the thigh support frame. The positions of the calf support frame and the thigh support frame can be adjusted to adapt to patients with different leg lengths to better fix the position of the legs, which is easy to operate and widely used in medical use.

[0015] 3. This adaptive medical joint fixator uses a sponge strip and a breathable net. During the use of the device, the sponge strip can absorb the sweat generated by the patient wearing the calf support and the thigh support during daily activities, thereby improving the dryness of the calf support and the thigh support. The breathable net can separate the legs from the sponge strip, so that the patient will not sweat during use, making it more comfortable for the patient to wear and more adaptive.
