That is, the energy button 30 may be used to control the activation and deactivation of the transducer 20, and when the energy button 30 is pressed, the transducer 20 activates and provides ultrasonic waves to the cutter.

In summary, the ultrasonic blade convenient to detach in this embodiment includes the energy button 30, and the connection mode of the energy button 30 and the housing 10 is a clamping connection, compared with the prior art, when the energy button 30 is damaged, the energy button 30 is directly taken down from the housing 10, so that the detaching efficiency of the energy button 30 is improved, and the detaching duration of the energy button 30 is shortened.

In addition, the ultrasonic knife convenient to disassemble in the embodiment does not need to adopt a pin to fix the energy button 30, so that the ultrasonic knife convenient to disassemble is simple in structure and low in cost.

In the present embodiment, as shown in fig. 3, the energy button 30 in the present embodiment may include a pressing portion 31 and a connecting portion 32. The connecting part 32 is clamped on the shell 10; the pressing portion 31 is connected to the connecting portion 32 and is used for being pressed by a user.

Further, as shown in fig. 3, the pressing part 31 may include a pressing block 311 and a pressing piece 312 connected. The pressing block 311 is used for being pressed by a user, and the pressing block 311 may be in a shell shape.

In this embodiment, as shown in fig. 1, the housing 10 may include a housing body 11 and a fixing portion 12 for being engaged with the connecting portion 32. The fixing portion 12 is located inside the housing 10.

Further, as shown in fig. 4, the side of the fixing portion 12 has a clamping groove, and the connecting portion 32 may be in a column shape, at this time, the connecting portion 32 is clamped in the clamping groove, so that the connecting portion 32 is clamped with the fixing portion 12, and the clamping of the energy button 30 and the housing 10 is further realized. Since the connecting portion 32 is in a cylindrical shape, the pressing portion 31 can rotate around the connecting portion 32 as a rotation axis, and thus the pressing portion 31 can be pressed or lifted. Alternatively, the snap-in recesses on the holding part 12 can be formed by a projection 411 on the side of the holding part 12. That is, the side of the fixing portion 12 may have a protrusion 411, and one end of the protrusion 411 has a clamping groove, and at this time, the connecting portion 32 is clamped in the clamping groove. Moreover, as shown in fig. 2, one side surface of the fixing portion 12 may have two first protrusion structures 121, and the two first protrusion structures 121 form two clamping grooves, so that the connecting portion 32 and the fixing portion 12 can be clamped more stably.

In this embodiment, as shown in fig. 1 or 5, the detachable ultrasonic blade may further include a functional component 40. The functional component 40 is located inside the housing 10, and the functional component 40 is configured to regulate the amount of electrical energy provided to the transducer 20 by the functional component 40 when the energy button 30 is pressed. The functional component 40 is located inside the ultrasonic blade convenient to detach, and compared with the situation that the functional component 40 in the prior art is located in the energy host, the size of the energy host is reduced, and the ultrasonic blade convenient to detach is convenient to carry. Fig. 5 is an exploded schematic view of the energy button 30, the fixing portion 12 and the functional component 40, and the schematic view is a bottom view.

Further, as shown in fig. 5, the functional component 40 includes a receiving portion 41 and a processing portion 42. Wherein the bottom of the fixing portion 12 may have a groove, and the receiving portion 41 is located in the groove. The receiving portion 41 is in contact with one end of the pressing portion 31, and the receiving portion 41 is configured to transmit a pressing signal of the pressing portion 31 to the processing portion 42 when the other end of the pressing portion 31 is pressed. The processing portion 42 is configured to adjust the amount of electrical energy provided to the transducer 20 in accordance with the compression signal.

Alternatively, the processing portion 42 may be connected between the energy host and the transducer 20, and when the energy host transmits the electric energy to the processing portion 42, the processing portion 42 may adjust the electric energy according to the pressing signal in the pressing portion 31 and transmit the processed electric energy to the transducer 20. For example, when the pressing signal of the pressing part 31 indicates that a small power needs to be supplied to the transducer 20, the processing part 42 may turn down the power transmitted to the processing part 42 and then transmit the power to the transducer 20, and at this time, the transducer 20 generates a small ultrasonic wave according to the small power and supplies the ultrasonic wave to the cutter, thereby enabling the cutter to process the cell tissue according to the needs of the user.

The pressure-sensitive sensor is disposed between the convex structure 411 and the fixing portion 12, and is electrically connected to the processing portion 42 through a wire 43. When the other end of the pressing part 31 is pressed, the other end of the pressing part 31 drives the convex structure 411 to press the pressure sensitive sensor configured to determine a pressing signal and transmit the pressing signal to the processing part 42.

Alternatively, the convex structure 411 may be located above the pressing piece 312 in the pressing portion 31, that is, the positional relationship of the convex structure 411, the pressure-sensitive sensor, and the pressing piece 312 is such that the pressure-sensitive sheet is located between the upper surface of the fixing portion 12 and the convex structure 411, and the convex structure 411 is located between the pressure-sensitive sensor and the pressing piece 312. Thus, when the pressing block 311 is pressed downwards, due to the existence of the connecting portion 32, the pressing sheet 312 has an upward movement tendency, so that the pressing sheet 312 applies an upward force to the convex structure 411 and is transmitted by the convex structure 411, so that the force pressing the pressing block 311 downwards is transmitted to the pressure sensitive sensor, so that the pressure sensitive sensor generates a pressing signal, and the pressure sensitive sensor can transmit the pressing signal to the processing portion 42 through the conducting wire 43.

Optionally, the processing portion 42 is configured to provide a magnitude of electrical energy to the transducer 20 that is positively correlated to a magnitude of pressure received by the pressure sensitive sensor. That is, the larger the pressing force received by the pressure sensitive sensor, the larger the generated pressing signal, the larger the electric power supplied to the transducer 20 by the processing portion 42, and the larger the ultrasonic wave supplied to the tool by the transducer 20. In turn, the smaller the pressing force received by the pressure sensitive sensor, the smaller the generated pressing signal, the smaller the electric power supplied to the transducer 20 by the processing portion 42, and the smaller the ultrasonic wave supplied to the tool by the transducer 20.

Optionally, as shown in fig. 1 and 5, the ultrasonic blade to facilitate detachment includes a first energy button 301 and a second energy button 302. The first energy button 301 is fastened to one side of the housing 10, and the second energy button 302 is fastened to the other side of the housing 10. Moreover, the fixing portion 12 of the first energy button 301 and the fixing portion 12 of the second energy button 302 can be the same fixing portion, and at this time, two sides of the fixing portion 12 can have a clamping groove.

Further, when the ultrasonic blade for facilitating detachment includes the first energy button 301 and the second energy button 302, the functional assembly 40 may include two receiving parts 41, the two receiving parts 41 are respectively connected with the pressing pieces 312 of the first energy button 301 and the second energy button 302, and the two receiving parts 41 are both electrically connected with the processing part 42.

Still further, referring to fig. 1, 5 or 6, the ultrasonic blade for easy detachment may further include a third energy button 303, and the third energy button 303 is clamped at one end of the housing 10 close to the cutter.

Illustratively, the end of the housing 10 near the cutter may have a snap groove, and the third power button 303 is snapped into the snap groove through the connection portion 32. Alternatively, as shown in fig. 6, one end of the third energy button 303 has a second protruding structure 3031, and the second protruding structure 3031 has a through hole. At this time, the third power button 303 and the case 10 may be fixed by a pin inserted into the through hole.

Optionally, when the detachable ultrasonic blade includes the third energy button 303, the functional assembly 40 may further include a receiving portion 41 for receiving a pressing signal of the third energy button 303, and the receiving portion 41 is connected to the processing portion 42. At this time, the third energy button may have thereon a third protruding structure 3032, and the third protruding structure 3032 is in contact with the receiving portion 41, so that when the third energy button 303 is pressed, the third protruding structure 3032 presses the receiving portion 41, so that the receiving portion 41 generates a pressing signal and transmits the pressing signal to the processing portion 42.

Since the three energy buttons 30 are located at different positions of the housing 10, the user can control the activation or deactivation of the transducer 20 through the different energy buttons 30, and the user's needs with different operating habits can be satisfied.

Optionally, in this embodiment, the transducer 20 includes a main body structure and two piezoelectric ceramics, a side surface of one end of the main body structure has two grooves, and the two piezoelectric ceramics are respectively located in the two grooves. One of the two piezoelectric ceramics is electrically connected with the first stage of the power supply, the other one is electrically connected with the second stage of the power supply, and the first stage and the second stage are opposite in electrical property. Because the transducer in the embodiment adopts two piezoelectric ceramics, the cost of the transducer is lower, and the cost of the ultrasonic knife convenient to disassemble is further reduced.

Alternatively, the energy host may include a power adapter electrically connected to the functional component 40 for providing energy to the functional component 40.

When the ultrasonic scalpel convenient to detach provided by the embodiment is used, the power adapter in the energy host is connected with the external power supply, then one end of the scalpel is extended into a body cavity, and the scalpel head in the scalpel is controlled to clamp cell tissues to be processed. After the tissue to be treated is clamped, the energy button 30 (any one of them is pressed when there are 3 energy buttons in the ultrasonic blade for easy detachment) is pressed to rapidly vibrate the transducer 20 and generate ultrasonic waves. When a larger ultrasonic wave is required for the tissue to be treated, the amplitude of pressing the energy button 30 can be increased, thereby enabling the transducer 20 to generate a larger ultrasonic wave to treat the tissue. After the cells are treated, the pressing of the energy adjusting button 30 is stopped, the ultrasonic blade convenient to detach is removed from the cavity, and simultaneously, the power plug is pulled out.
