Special medical hammer for knee jerk reflex test

Abstract

The invention discloses a special medical hammer for a knee jerk reflex test. The special medical hammer comprises a hammer head, wherein a contact head is connected in the hammer head in a sliding manner, a fixed block is fixedly connected to the right side of the contact head, a two-section rod is rotationally connected in the fixed block, the right side of the fixed block is fixedly connected with a buffer spring, the bottom of the two-section rod is rotationally connected with a limiting rod, the right side of a transition box is fixedly connected with a communicating pipe, the side surface of the communicating pipe is fixedly connected with an auxiliary threaded rod, a rotating wheel is connected to the surface of the auxiliary threaded rod in an engaged manner, a squeezing block is connected to the right side of the rotating wheel in a sliding manner, the right side of the squeezing block is fixedly connected with a transmission toothed bar, and the side surface of the transmission toothed bar is connected with a wind shielding wheel in an engaged manner. Through cooperative use of the fixed block and the squeezing wheel, the special medical hammer for the knee jerk reflex test has the effects of automatically adjusting force during knocking and preventing pain and discomfort of a knocked person due to too large knocking force.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a special medical hammer for knee jerk reflex testing. Background technique [0002] Knee jerk response, also known as knee jerk reflex, is one of the simplest reflex types. It only contains two neurons. The basic way of neuromodulation is reflex. The whole nerve conduction pathway from receiving stimulation to response is called reflex arc. , in the teaching demonstration, it is necessary to use a special hammer to hit the knee to observe the whole process. [0003] When hitting the knee with a hammer, the knocker often cannot grasp the force of the knock. When the force is small, the knee jerk reflex effect is not obvious. When the force is high, it will cause pain and discomfort to the person being knocked. An appropriate tapping force is an important issue, but the existing medical hammer cannot adjust the force, and the percussionist can only control the force by experienc...
