Description

Neurology percussion hammer

Technical Field

The utility model belongs to the technical field of neurology, and particularly relates to a neurology percussion hammer.

Background

Neural reflex is the fundamental way of human life activity. Once the nervous system is defective, pathological reflexes occur. Pathological reflexes refer to abnormal reflexes that occur when the central nervous system is damaged. Percussion hammers are instruments used by doctors to examine neuromuscular reflex, such as when examining the patient's knee reflex, to let the patient sit in a sitting position, hang the feet for relaxation, and the doctor taps the knee with the percussion hammer. Normal people can cause the quadriceps (a muscle in front of the thigh) to contract and the calf to rise. This reflection is called the tendon of knee reflection. The knee tendon reflex is centrally located in the spinal cord, and thus, this examination does not check whether the knee is ill or not, but checks whether the knee reflex of the spinal reflex center is normal.
