A mechatronic medical traction device

Abstract

The invention discloses an electromechanical integrated medical traction device. The device comprise a back fixing part, a head fixing part, two leg fixing parts, foot fixing parts and a bandage. The two leg fixing parts are hinged to the lower end of the back fixing part and used for fixing two legs, the foot fixing parts are arranged at the lower ends of the two leg fixing parts respectively and used for fixing feet, the bandage comprises a meshed polymer foam material coated with a viscous material, and the mesh surface area of the foam material is at least 33% of the total surface area of the bandage. When foot supporting plates and a head supporting plate become far away from a back supporting plate and shank supporting plates due to traction parts so as to achieve body traction, hip joints and knee joints of the body can still move slightly, and the traction effect is not affected. Compared with the prior art that the body is fixed to a platform, the fatigue and restraint feeling of a patient is reduced.

Description

technical field [0001] The invention relates to the technical field of mechatronics, in particular to a mechatronics medical traction device. Background technique [0002] The traction device is a medical device commonly used in orthopedics, and its purpose is to pull the human body to correct the human skeleton. The traction device in the prior art includes a platform (or bed) for the patient to lie flat, and is used to fix the lower limbs of the human body and / or Or the upper body is used to fix the body and the traction mechanism is used to pull the head and / or lower limbs to increase the bone joint gap. The traction device mainly provides traction through the extension spring. [0003] Although the above-mentioned traction device can play a traction effect, it has the following disadvantages: [0004] 1. The patient lies on the platform and is fixed by the fixing mechanism. The patient cannot perform any slight activities, which increases the fatigue of the patient. ...

AI Technical Summary

Problems solved by technology

[0004] 1. The patient lies on the platform and is fixed by the fixing mechanism. The patient cannot perform any slight activities, which increases the fatigue of the patient.

[0005] 2. Since the traction force is provided by the tension spring, but as the gap between the bones increases, the stretching amount of the tension spring decreases continuously, and the traction force decreases continuously. In general, the traction force needs to be kept constant during the entire traction process. And the continuous reduction of traction force will not get better traction effect

[0006] 3. The length and size of the platform in the prior art is fixed and cannot adapt to patients of different heights, thereby reducing the number of people applicable to the entire traction device
