Description

A kind of medical knee joint splint

technical field

The invention relates to the technical field of medical equipment, in particular to a medical knee joint splint.

Background technique

The knee joint is composed of the medial and lateral condyles of the femur, the medial and lateral tibial condyles, the meniscus and the patella. Fixed support. The rehabilitation of the injured knee joint has a lot to do with the post-injury treatment. Usually, at the initial stage of the injury, it is necessary to minimize or even prohibit its activities. After the bone is automatically repaired, the joint can be moved in a gradual manner.

At present, there are mainly two types of knee joint fixation, one is internal fixation and the other is external fixation. The internal fixation treatment mainly involves implanting a support in the body, which causes a lot of bleeding and a large wound, and requires a second operation to take out the implant, which is complicated and expensive. External fixation usually uses gypsum and splint to completely fix the knee joint. Due to the long treatment time, it often leads to the later stage of treatment. The knee joint cannot be effectively exercised and becomes stiff, which damages the function of the knee joint.

The main way of external fixation is: put the knee in the flexion position of 10-20 degrees, and fix it with plaster before and after the knee joint. Internal fixation surgery is: After the operation, the knee joint is usually fixed in a straight position with front and rear long-leg plaster, and the injured limb is raised. That is, in the prior art, whether it is internal fixation or external fixation, the patient's knee joint must be completely fixed so that the knee joint can achieve a stable effect.

Traditional external fixation methods include external fixation brackets, splints, straps, plaster, etc. The traditional method is inconvenient to apply, difficult to nurse, inaccurate to support, and does not provide good support for the rehabilitation of the affected area in the later stage, all of which bring inconvenience to the patient. Among them, the structure of the external fixator is complex, heavy, inconvenient to wear, and high in cost. The reliability of splint fixation is poor, and it cannot achieve a good geometric shape match with the wearing area, which is prone to stress concentration, poor air permeability, and long-term matching will cause discomfort. The operation of plaster fixation is complicated, and the production time is long. The fixation effect is related to the proficiency of the maker. And the gypsum has damage to the skin of the operator and the patient; it is heavy, solidifies slowly, and is inconvenient to use; the gas permeability of the gypsum is poor; it is difficult to observe the skin and wound conditions when using the gypsum.

That is to say, the patient's knee joint is fixed by cooperation from the front, left rear and right rear. It should be noted that the lengths of the front splint 1, the left rear splint 4 and the right rear splint 5 can be set according to the needs of fixing the patient's knee joint, such as the corresponding lengths wrapped around the thigh above the knee joint and the calf below the knee joint to achieve The purpose of stabilizing and immobilizing the patient's knee joint.

The left rear splint 4 is detachably fixedly connected to the front splint 1, and the right rear splint 5 is detachably fixedly connected to the front splint 1. Therefore, when fixing the patient, the three can be adjusted to the preset positions first, and then the three connect. When it is necessary to observe the condition of the wound, the three can also be disassembled conveniently, and then the three can be assembled after the observation is completed. Therefore, it is more convenient to use. The specific detachable connection relationship among the three can be set as required.

The inner surfaces of the front splint 1 , the left rear splint 4 and the right rear splint 5 respectively match the geometry of the patient's knee joint. That is to say, the inner surfaces of the front splint 1, the left rear splint 4 and the right rear splint 5 are configured to conform to the shape of the corresponding position of the patient's knee joint, so that they can fit well with the affected part after installation. It should be noted that when the knee joint is fixed, it is usually necessary to act on the upper half of the calf, the knee joint and the lower half of the thigh, so the above-mentioned knee joint can specifically include the upper half of the calf, the knee joint and the lower half of the thigh. , that is, the inner surfaces of the front splint 1, the left rear splint 4 and the right rear splint 5 are all matched with the geometry of the corresponding upper half of the patient's calf, knee joint and lower thigh.
