Description

  The present invention relates to a tendon reflex education apparatus capable of reproducing tendon reflex movement using existing measurement data and supporting a medical practitioner to acquire a tendon reflex examination technique and a motion measurement technique.

  With the progress of aging, diseases caused by central neuropathy and diseases caused by peripheral neuropathy such as diabetic neuropathy are increasing. Early diagnosis and early treatment are very important for the disease, and improvement of diagnostic techniques is strongly demanded.

  Diagnosis of diseases caused by central and peripheral neuropathy involves first estimating the site of injury using a nerve examination technique typified by tendon reflexes, and using a CT scanner (computer tomography device) It is confirmed by adding an auxiliary diagnosis represented by an image examination such as MRI (nuclear magnetic resonance imaging) or a functional examination such as an electromyograph.

  The tendon reflex is one of the examination techniques that provide the most information when estimating the nerve damage site, and is also commonly used as a “legal breath examination technique”. This is a medical examination technique in which the degree of movement of the limbs is visually confirmed and information can be obtained in a short time, and the tool used is only a hammer and is low cost.

  For patients, it is costly and time-consuming to undergo a CT scanner, MRI, etc. at a medical institution. If the disorder can be identified by the tendon reflex in the previous stage, the medical economy will be improved. Technical improvement is required.

  FIG. 19 is a diagram showing a mechanism of tendon reflex. The tendon reflex 16 is based on a mechanism in which when a sensor in the muscle senses extension, a signal is sent to the spinal cord and brain via the peripheral nerve, and the stretched muscle is contracted so as not to grow too much through the nerve toward the muscle. It is.

  When the tendon device 8 such as a hammer hits the tendon 16c in the vicinity of the knee of the patient's leg 16a with a hammer 16i, the quadriceps 16b, which is one of the thigh muscles, expands. When the muscle spindle 16d, which is an intramuscular sensor, senses the extension of the quadriceps muscle 16b, the extension signal 16j is transmitted to the spinal cord 16f, which is the central nerve, through the nerve fiber 16e, which is the peripheral nerve.

  In the spinal cord 16f, the contraction signal 16k is transmitted to the motor fiber 16h, which is another peripheral nerve, via the synapse 16g that is a connection portion between the nerves. When the motion fiber 16h is stimulated by the contraction signal 16k, the quadriceps 16b contracts and appears as a reflection 16l that the patient's leg 16a rises.

  The mechanism of the tendon reflex 16 is controlled by the central nervous system, and if the upper nervous system fails, the suppression becomes ineffective and the reflex 16l becomes larger, and if the lower nervous system fails, information transmission is performed. It becomes insufficient and the reflection 16l becomes small. By using the characteristics of the tendon reflex 16, it is possible to estimate the damaged sites of the central nerve and the peripheral nerve.

  Tendon reflexes are observed not only at knees but also at ankle joints, shoulder joints or elbow joints, and are measured at many joints at the time of examination. Estimate the nerve damage site from the measurement results and determine the examination site and examination item. If the estimation is incorrect or the narrowing down is insufficient, a misdiagnosis may occur due to an underexamination, or medical expenses will increase due to an overexamination. Or

As described in Patent Document 1, as an apparatus that reproduces tendon reflexes, an actuator unit in which a rod is moved by air pressure is attached to both ends of a joint unit, and a rod displacement control is performed by feeding back a position detection amount of the rod. In addition, an invention of an artificial muscle joint drive device that performs stretch reflex control and reciprocal innervation is also disclosed.
