[0002] The ultrasonic scalpel is a necessary tool for ultrasonic treatment. The application principle of the ultrasonic scalpel is to convert electrical energy into mechanical vibration through a transducer, and transmit the vibration to the tool head through a guide rod, so that the tool head generates mechanical oscillation, which plays a role in cutting and coagulating animal or human tissues. Due to the advantages of high cutting accuracy, less bleeding and less thermal damage, the ultrasonic scalpel is widely used in surgical operations.

[0003] When the ultrasonic scalpel is produced, in order to meet the anti-sticking and wear-resistant requirements of the ultrasonic scalpel, an anti-sticking and wear-resistant coating, such as a polymer Teflon coating, needs to be coated on the surface of the ultrasonic scalpel. Therefore, in order to meet the high-quality production of the ultrasonic scalpel, a sampling inspection of the stability test of the coating needs to be carried out before the ultrasonic scalpel leaves the factory;

[0004] For example, a friction and wear tester with the publication number CN219121958U includes a pressure application device, a test device and a control device. The pressure application device includes a base, a support frame, a first motor, a cylinder and a friction and wear head. The support frame is installed on the base, the first motor is fixed on the support frame, and the cylinder is connected to the first motor and can slide up and down on the guide rail of the first motor; the test device includes a second motor, a test platform and a fixing piece. The second motor is fixedly installed on the base, the test platform is installed on the second motor, and the fixing piece is installed on the test platform and can fix the ultrasonic scalpel sample. The friction and wear tester provided by the utility model can quickly and accurately measure the mechanical strength and durability of the coating and the substrate by adjusting the cylinder and the second motor, and the instrument is simple to operate, convenient and fast.

A clamping assembly 11 is provided on the turntable 9. The minimum clamping positions of the clamping assembly 11 are all directly below the output ends of the three groups of electric push rods 4;

[0024] The three groups of electric push rods 4 and the motor 8 are both electrically connected to the control device 2. The control device 2 can independently control the three groups of electric push rods 4 and the motor 8. The model is: KG316T, or the control device can also adopt the control device in a friction and wear tester with the publication number CN219121958U in the background technology; such as controlling the downward thrust of the electric push rod 4, the telescopic length of the electric push rod 4, the rotation direction of the motor 8, and the rotation speed of the motor 8 to achieve precise pressure control of the sample to be tested and change the friction direction;

[0025] Preferably: The surface of the protective cover 6 is provided with heat dissipation holes 7, and the protective cover 6 is communicated with the bottom surface of the base 1.

[0026] During specific use, through the opened heat dissipation holes 7, the heat generated by the operation of the motor 8 can be better dissipated. Secondly, through the bottom of the base 1, the motor 8 can be conveniently disassembled and repaired, effectively improving the service life of the motor 8.

[0027] Preferably: The output end of the motor 8 penetrates through the top of the protective cover 6 and is connected to the turntable 9 through a coupling 10.

[0028] During specific use, when the motor 8 is controlled to rotate by the control device 2, the motor 8 can drive the turntable 9 to rotate, thereby realizing the rotation of multiple ultrasonic scalpel samples on the turntable 9, facilitating the simultaneous testing of multiple samples.

[0029] Preferably: a disk body 901 and an adjustment groove 902. The adjustment groove 902 is opened inside the disk body 901. The clamping assembly 11 includes: a backing plate 1101, an adjustment bolt 1102, an adjustment knob 1103, a rotating shaft 1104, and a clamping plate 1105.
