Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a lower limb strength trainer for neurosurgery. Background Art

[0002] Neurosurgery is a branch of surgery. Based on surgery as the main treatment method, it applies unique neurosurgical research methods to study the human nervous system, such as the brain, spinal cord, and peripheral nervous system, as well as related accessory organs, such as the skull, scalp, cerebral blood vessels, meninges, etc. for injuries, inflammations, tumors, deformities, and certain genetic metabolic disorders or functional disorders.

[0003] There are the following problems: When rehabilitating patients after neurosurgery, strength training is required for the lower limbs of the patients to recover walking. However, the existing trainers cannot adjust the strength of the trainer according to the needs and recovery degree of the patients, thus affecting the rehabilitation training effect of the patients.

[0004] In view of this, in response to the existing problems, research and improvement are carried out to provide a lower limb strength trainer for neurosurgery. By setting the connection mode between the threaded rod and the bearing plate, the rotating threaded rod can move left and right inside the bearing plate wall. At the same time, the length of the training equipment at the top of the threaded rod will also change accordingly. When the threaded rod moves to the left, the length of the compression spring will shorten, and at this time, the strength of the trainer will increase. When the threaded rod moves to the right, the length of the compression spring will elongate, and at this time, the strength of the trainer will decrease. This not only plays a role in adjusting the strength of the trainer but also improves the rehabilitation training effect of the patients, aiming to solve the problems and improve the practical value through this technology.
