Description
Technical Field
The invention relates to a physiological experiment appliance, in particular to a physiological experiment muscle groove with a fixing function.
Background
In the functional experiment, namely the experiment of the influence of the stimulation intensity and frequency on the contraction of the femoral muscle, the broken end of the femur separated from the experimental body is required to be fixed in the physiological muscle slot jack, and the action potential generated by the sciatic nerve is transmitted to a computer through an electrode so as to be convenient for an operator to observe and analyze.
However, in actual operation, the broken end of the femur is too short or deformed due to the fact that the operator does not carefully separate or the femur is deformed, so that the operator cannot fix the femur, and experimental failure or inaccurate experimental data are caused.
Disclosure of Invention
The invention aims to provide a physiological experiment muscle groove with a fixing function so as to solve the problem that in the prior art, the broken end of a femur is too short or deformed to complete an experiment.
The physiological experiment muscle groove with the fixing function in this scheme, including the fixed plate, set up movable groove on the fixed plate, install the fixing base in the movable groove, be equipped with electrode hole and the fixed orifices that the level runs through the fixing base on the fixing base, be equipped with the electrode in the electrode hole, be provided with the fixed axle in the fixed orifices, the one end of electrode and fixed axle all is connected with electrode joint, and the other end of fixed axle is equipped with annular clamping piece, be equipped with the logical chamber that runs through the fixed axle and coaxial line on the fixed axle, be equipped with the fixed probe that one end links to each other with electrode joint in the logical intracavity, set up on the clamping piece and be used for clamping piece shrink or open breach, cup jointed fixed cover on the clamping piece outer wall, be equipped with the spring between fixed cover and the clamping piece, spring and fixed cover coaxial line, fixed probe's the other end is located the clamping piece.
The working principle of the scheme is as follows: when the femur fixing device is used, an operator slides the fixing sleeve by one hand, so that the clamping piece is not extruded by the fixing sleeve, the clamping piece is outwards opened due to the outwards-stretching elastic force of the clamping piece, meanwhile, the operator lifts one section of femur by the other hand, the fixing probe enters the femur through the femur broken end, and the femur broken end is placed in the clamping piece, so that the femur is initially positioned in the clamping piece; after the positioning is finished, an operator releases the fixing sleeve, the fixing sleeve rebounds under the action of the spring, the clamping piece is forced to retract inwards from the original external tension, the clamping piece is deformed due to the blocking of the femur in the clamping piece, and the rebounded fixing sleeve is clamped by the deformed clamping piece, so that the clamping piece is fixed to the femur.
The beneficial effect of this scheme: because the clamping piece is provided with the notch for shrinking or expanding the clamping piece, the size of deformed femur can be met, and the fixing sleeve is outwards extruded by the spring under the action of the spring, so that the clamping piece is shrunk by the shrinkage force of the coming fixing sleeve, the clamping piece is enabled to generate pressure on the femur, and the femur is fixed on the fixing probe under the action of the pressure.
Further, the inner walls of the through cavity and the clamping piece are covered with glass fiber layers for insulation. Since the glass fiber layer is insulating, the interference to action potential caused by contact of the fixing sleeve with sciatic nerve can be avoided.
Further, the inner wall of the clamping piece is provided with fixing teeth for fixing the femur. The stability of the femur and the clamping piece is increased by the fixed teeth.
Further, a limiting ring for limiting the movement of the fixing sleeve is fixedly arranged on the outer wall of the clamping piece. The fixing sleeve is prevented from falling off from the clamping piece.
Further, the fixed shaft is connected with the front face by adopting threads. And the fixed shaft is convenient to replace by adopting threaded connection.
