Neurological clinical percussion hammer for testing knee-jerk response

Abstract

The invention discloses a neurological clinical percussion hammer for testing a knee-jerk response. The neurological clinical percussion hammer includes a hammer body and an adjustable handle. The upper end face of the hammer body is provided with a first clamping groove. The first clamping groove is internally provided with a large hammer head, the lower end surface of the hammer body is providedwith a second clamping groove, a small hammer head is arranged in the second clamping groove, and pressure measuring devices are arranged in the middle of the upper end surface of the large hammer head and the middle of the lower end surface of the small hammer head. The middle part of the front side of the hammer body is provided with a pin hole, and a positioning pin is arranged in the pin hole. The neurological clinical percussion hammer is simple in structure and convenient to use, and non-slip measures are taken, thereby effectively preventing the percussion hammer from falling off and ensuring a patient's safety. A counterweight is replaced by adjusting the length of a hammer handle, scratch that may be caused to medical workers by a thread on the outer surface of a hammer rod is avoided, the safety of the medical workers is ensured, pressure borne by the patient can be effectively monitored, and physical damage to the patient caused by too much pressure received by the patientis avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a neurology clinical percussion hammer for testing knee jerk response. Background technique [0002] The neurology department often uses a percussion hammer when examining the patient's nerve sensitivity. The medical staff uses the percussion hammer to detect whether the patient's knee jerk reflex is normal. For example, the patent application publication number CN201621138629 discloses a neurology percussion hammer for testing the knee jerk response. However, there are some defects in the use of the above patents. The handle does not have anti-slip measures, which may cause the percussion hammer to fall off and cause injury to the patient. Secondly, the workload of the medical staff will increase the weight of the counterweight. Finally, it will not be able to respond in real time. The amount of pressure applied during the measurement is likely to cause injury to those w...
