Shock is a physical phenomenon in which the force, velocity, acceleration and displacement of a structural system are suddenly changed by a short excitation time. The impact is violent and is a sudden, violent process of energy release, energy conversion and energy transfer. The invention considers the problem of simple carrying and operation, and the designed device is selected to quickly release the impact kinetic energy to carry out the impact crushing treatment on the ganglion cyst 1. Since the head of the device only exerts a large impact kinetic energy in the contact region and the impact distribution in this region is not significant, the impact force can be treated as a concentrated force.
The side wall of the housing 20 is provided with a fixed calibration device 21, the fixed calibration device 21 is provided with a calibration screw and a calibration slot, the calibration screw is clamped into the calibration slot through the fixed calibration device 21, and the fixed impact head 28 is controlled not to rotate in the launching process.
The outer side wall of the striking device 23 is provided with a transmitting device 22, and the transmitting device 22 is energy-locked through a transmitting switch.

The disc shape is convenient for holding by hand, the gripping force is strong, and the pull rod 26 provides main external power for the therapeutic apparatus. The outer diameter of the pull rod 26 is smaller than the inner diameter of the sleeve 25, the pull rod and the sleeve are embedded with each other, the pulling is convenient and labor-saving, and the operation is convenient.
The specific process of energy locking is as follows; the handle 27 of the pull rod is pulled to enable the pull rod to drive the striking device 23 to move relative to the shell 20, the striking device 23 is pressed to generate impact kinetic energy until the limiting pin is ejected out of the limiting hole in the launching device 22, the spring 24 is in a gradually compressed state in the process that the pull rod 26 stretches outwards, and the spring 24 is compressed to the maximum extent and keeps the state, so that the impact kinetic energy is locked, and energy locking is achieved.
In consideration of the problems of material strength and weight, the metal aluminum is selected as the main material for generating impact kinetic energy of the therapeutic apparatus, so that the strength of the material cannot be damaged when the impact force is generated to impact and break, and the inconvenience in carrying caused by overlarge mass is avoided. However, because the mechanical properties of the metal material and the skin are greatly different, and the metal aluminum directly contacts with the skin to cause pain of a patient when the metal aluminum is impacted and broken, the front end of the aluminum head is attached with a layer of acoustic impedance material, so that the pain generated when the metal aluminum is impacted and broken can be properly reduced. In order to enhance the impact force striking effect and concentrate the acting force, the acoustic impedance material at the front end of the metal aluminum of the striking device 23 is set to be convex with non-uniform radial radius (as shown in fig. 4-6). With the center of the outer end surface of the impact head 28 as a reference, a protrusion is arranged at intervals along the radius of the outer end surface of the impact head 28, and the radius of the protrusion is relatively increased, so that the front end of the striking device 23 looks like a concave curved surface as a whole (as shown in fig. 5). When the local pressure is increased, the contact area can be reduced, the concentrated force can be increased, and the ganglion cyst 1 can be quickly crushed by impact. The general appearance of ganglion 1 is smooth, and is the circular lump of unbonded that surface skin can promote, although the root is fixed, nevertheless can unavoidably warp when strikeing the breakage, causes to strike that the breakage is incomplete, strikes the head curve and can contain the circular lump of cyst wherein, reduces unnecessary and warp, alleviates pain, makes the frictional force increase simultaneously, and unnecessary when avoiding strikeing the breakage slides, makes to strike the breakage more stable. The radius r of the spherical projection in the impact head 28 is set to the formula (1):
the radius of the concave curved surface at the end of the impact head 28 is set to be R, the center of the curved surface is taken as the origin of the coordinate axis, the transverse coordinate of the curved surface is x, and the longitudinal height of the curved surface is y.
The free end of the housing 20 is contoured as a cosine function of a trigonometric function.
Considering that when the impact kinetic energy is generated, a closed space is formed between the structure generating the impact kinetic energy in the therapeutic apparatus and the end part of the therapeutic apparatus shell 20, and the space can generate a certain pressure inside due to the action of the therapeutic apparatus and form a pressure difference with the external atmospheric pressure, thereby influencing the impact crushing effect. Therefore, in order to balance the internal and external pressures, a continuous protrusion is provided at the end of the housing 20 (as shown in fig. 7), so that the therapeutic apparatus can ensure balance between the internal and external pressures when in use, wherein the curve formula is (2):
wherein, with reference to the side view of the housing in fig. 7, a rectangular coordinate system of a plane is established, wherein the x-axis is coplanar with the end of the housing and the longitudinal height is y. Therefore, when the therapeutic apparatus generates impact kinetic energy, the vacuum inside generated by the therapeutic apparatus can flow with the external environment in an air interaction manner, and the impact crushing effect of the therapeutic apparatus cannot be influenced due to different internal and external pressures. Meanwhile, the continuous convex part of the therapeutic instrument shell 20 and the convex part at the front end of the striking device can be matched in a geometric structure, when a patient uses the therapeutic instrument, the radial convex part at the front end of the striking device 23 is in contact with skin, the convex part is originally diffused and displaced around after being extruded, and the convex part is matched with the convex part at the end part of the shell 20 to limit the displacement of the diffused cyst, so that the convex part is fully expanded downwards, unnecessary deformation is reduced, and the impact on the crushed ganglion cyst 1 is more stable.
As shown in fig. 1, the application process of the ganglion 1 therapeutic apparatus based on the dynamic principle of impact comprises the following steps:
(1) after finding that the ganglion 1 is generated at the back of the wrist, holding the shell 20 by one hand and fixing the same, holding the tail end of the pull rod 26 by the other hand and stretching the same outwards, pressing the striking device 23 to generate impact kinetic energy until the limit pin is ejected out of the limit hole in the emission device 22, wherein in the process of stretching the pull rod 26 outwards, the spring 24 is in a gradually compressed state until the spring 24 is compressed to the maximum extent and keeps the state, and the impact kinetic energy is locked;
(2) vertically placing the therapeutic apparatus on the back of the hand, aligning the impact head 28 at the end of the shell 20 with the ganglion 1, containing the ganglion 1 therein, and pressing downwards to control the therapeutic apparatus not to move on the back of the hand;
