Detailed Description

The invention will be further described with reference to the accompanying drawings:

example 1:

as shown in figure 1, the device comprises a controllable hammer head 1, a fixed hammer head 2, a hammer body 3, a hammer handle 4, a controllable hammer head switch 5, an indicator 6, a metal head 7, a pressure sensor 8 and a battery 9. Hammer block 3 is by controllable tup 1, pressure sensor 8 and fixed tup 2 are constituteed, wherein fixed tup 2 is solid hammer, controllable tup 1 comprises a plurality of metal heads 7 of closely arranging, pressure sensor 8 measures the dynamics of kowtowing, hammer handle 4 is by controllable tup switch 5, register 6 and battery 9 are constituteed, thereby adjust the area of kowtowing through the flexible state that controllable tup switch 5 changed the metal head, register 6 is connected with pressure sensor 8 and is used for showing the dynamics of kowtowing, entire system's power is provided by battery 9.

The fixed hammer head 2 is a solid hammer for simple percussion. The controllable hammer head 1 consists of 52 metal heads 7 which are completely identical in shape and are closely arranged, and the tapping surface of each metal head 7 is a square with the side length of 1 mm. The metal heads 7 of the controllable hammer head 1 are divided into two parts, and the upper 26 metal heads 7 are of a telescopic structure and form an upper half telescopic percussion surface 14; the lower 26 metal heads 7 form a lower half fixed percussion surface 15 and are not telescopic. The extension and retraction of the upper retractable percussion surface 14 is controlled by a controllable hammer head switch 5, which has two working positions, "pop-up" and "push-down". As shown in fig. 3b, when the controllable hammer switch 5 is located at the "press-down" working position, the rack 12 drives the gear 13 to rotate clockwise, the wire 11 is tensioned, the upper half retractable percussion surface 14 is retracted back to the hammer body 3, and only the lower half fixed percussion surface is located at the working position, so as to form an approximately semicircular percussion surface, as shown in fig. 2 b. As shown in fig. 3a, when the controllable hammer switch 5 is located at the "pop-up" working position, the rack 12 drives the gear 13 to rotate counterclockwise, the wire 11 is loosened, the upper half portion of the retractable percussion surface 14 moves to the working position under the action of the spring 10, and at this time, all 52 metal heads 7 are located at the working position, forming an approximately circular percussion surface, as shown in fig. 2 a. Thus, the adjustability of the round or semicircular percussion surface is realized by the selection of the controllable switch 5.

The counter 6 on the hammer handle 4 is connected with the pressure sensor 8 in the controllable hammer head 1 to display the percussion strength. The measurement range of the pressure sensor 8 is set to be 0-99 kg, and when a doctor uses the controllable hammer head 1 to do percussion work, the counter 6 can display percussion readings between 0-99 kg in time. According to the normal biting force of a human body, 25-65 kg is considered as a normal biting force interval, when the number displayed by the indicator 6 is in the interval, a green indication is displayed, when the displayed number exceeds 65kg, a red indication is displayed, and when the displayed number is lower than 25kg, a yellow indication is displayed.

The utility model discloses a design that the percussion dynamics can show, the area of percussion is adjustable has quantificationally the result of percussion, has solved the percussion instrument percussion dynamics commonly used that exists at present uncertain, uncontrollable, the scope inaccuracy scheduling problem, can provide more accurate inspection foundation for the diagnosis of all kinds of diseases in oral cavity.
