[0024] Unless the context otherwise requires, throughout the specification and claims, the term "comprising" is interpreted as open-ended and encompassing, meaning "including, but not limited to." In the description of the specification, terms such as "one embodiment," "some embodiments," "exemplary embodiment," "example," or "some examples" are intended to indicate that a particular feature, structure, material, or characteristic associated with that embodiment or example is included in at least one embodiment or example of this disclosure. The illustrative representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics mentioned may be included in any suitable manner in any one or more embodiments or examples.
[0025] This utility model embodiment provides an integrated ultrasonic scalpel, such as Figure 1 As shown, the device includes two main components: a power adapter 1 and an ultrasonic scalpel handle 2, which are connected by a wire. In actual operation, simply plug the power adapter 1 into a power source and control the ultrasonic scalpel cutting operation using the switch button on the outside of the ultrasonic scalpel handle 2.
[0026] In some embodiments, the power adapter 1 includes an ultrasonic generator 11 and a power module 12. The power module 12 provides power and drives the ultrasonic knife handle 2 through the ultrasonic generator 11, causing the ultrasonic knife handle 2 to cut objects at a high frequency of 20 kHz to 40 kHz.
[0027] The ultrasonic generator 11 includes components such as a PCB motherboard, a ceramic canister, an NPN transistor, a heat dissipation module, and a cooling fan, which will not be described in detail here.
[0028] An ultrasonic generator can be driven by an externally excited power transistor to output ultrasonic waves, or it can be driven by a self-excited power transistor to output ultrasonic waves.
[0029] This invention integrates a miniaturized ultrasonic generator 11 and a power module 12, presenting the whole as a power adapter 1, thus achieving the portability and miniaturization of the ultrasonic scalpel.
[0030] In some embodiments, the ultrasonic knife handle 2 includes an ultrasonic vibrating plate 21, an amplitude transformer 22, a clamping plate 23, and a blade 24. The ultrasonic vibrating plate 21 is fixedly connected to the amplitude transformer 22, and the ultrasonic vibrating plate 21 is in contact with one end of the amplitude transformer 22. The other end of the amplitude transformer 22 is fixedly connected to the blade 24 through the clamping plate 23.
[0031] It should be noted that this utility model does not limit the connection method of the ultrasonic vibrating plate 21 and the amplitude transformer 22. The ultrasonic vibrating plate 21 and the amplitude transformer 22 can be connected in various ways, such as by threaded connection, spring compression connection, or adhesive bonding.
[0032] The end of the amplitude rod 22 that is fixedly connected to the blade 24 is provided with a groove. The clamp 23 is fixed in the groove by screws, thereby fixing it to one end of the amplitude rod 22 and thus fixing the blade 24.
[0033] In some embodiments, the ultrasonic scalpel handle 2 further includes a rear cover plate 25, which is fixed to the end of the ultrasonic vibrating plate 21 away from the amplitude transformer 22, and fixes the ultrasonic vibrating plate 21 to the amplitude transformer 22. The rear cover plate 25 presses the ultrasonic vibrating plate 21 against one end of the amplitude transformer 22. When the ultrasonic vibrating plate 21 is energized, it generates mechanical vibration of a corresponding frequency, thereby transmitting ultrasonic energy to the amplitude transformer 22 in contact with it.
[0034] In some examples, the ultrasonic scalpel handle 2 also includes a screw 26, and the rear cover plate 25 is provided with a through hole 251, through which the screw 26 passes and is connected to the ultrasonic vibrating plate 21.
[0035] The through hole 251 is provided with an internal thread, and one end of the luffing rod 22 is also provided with an internal thread. The screw 26 is connected to the rear cover plate 25 and the luffing rod 22 respectively through the internal thread, thereby connecting the rear cover plate 25 and the luffing rod 22.
[0036] In some examples, the ultrasonic scalpel handle 2 also includes an insulating tube 27, which is sleeved on the outside of the screw 26. The insulating tube 27 serves to insulate the screw 26 from the ultrasonic vibrating plate 21.
[0037] In some embodiments, the ultrasonic vibrating plate 21 includes an annular piezoelectric ceramic plate 211, the center of which coincides with the central axis of the amplitude transformer 22.
[0038] Multiple piezoelectric ceramic sheets 211 are provided, and the centers of the multiple piezoelectric ceramic sheets 211 coincide with the central axis of the amplitude transformer 22.
[0039] The central hole of the piezoelectric ceramic sheet 211 can be used to pass through the screw 26, thereby fixing the piezoelectric ceramic sheet 211 to the amplitude transformer 22 via threads. By using the annular piezoelectric ceramic sheet 211, the piezoelectric ceramic sheet 211 can be more tightly connected to the amplitude transformer 22 via threads, improving the transmission efficiency of ultrasonic energy.
[0040] In some examples, the ultrasonic vibrating plate 21 also includes an electrode plate 212, with the piezoelectric ceramic plate 211 spaced apart from the electrode plate 212.
[0041] Multiple electrode plates 212 are also provided, and multiple electrode plates 212 and multiple piezoelectric ceramic plates 211 are arranged at intervals.
[0042] When the electrode plate 212 is energized, it generates mechanical vibration of a corresponding frequency under the control of the main controller, thereby transmitting ultrasonic energy to the amplitude transformer 22 in contact with it.
[0043] In some embodiments, the cross-sectional areas at both ends of the amplitude rod 22 are different, with one end of the amplitude rod 22 having a larger cross-sectional area and the other end having a smaller cross-sectional area.
[0044] The end of the amplitude transformer 22 with the larger cross-sectional area is connected to the ultrasonic vibrating plate 21, and the end with the smaller cross-sectional area is connected to the blade 24. The end of the amplitude transformer 22 with the smaller cross-sectional area can come into contact with biological tissue through the blade 24, and the output ultrasonic energy can be used to cut, coagulate, and perform other operations on the biological tissue.
[0045] In some embodiments, the amplitude transformer 22 is a one-piece molded structure. The one-piece molded amplitude transformer 22 can fully transfer the ultrasonic energy generated by the ultrasonic vibrator 21 to the end of the amplitude transformer 22 with a smaller cross-sectional area, thereby further reducing the loss of ultrasonic energy.
[0046] In some embodiments, the ultrasonic scalpel handle 2 further includes a shock-absorbing rubber ring 28, which is sleeved on the outside of the amplitude transformer 22.
[0047] In some embodiments, the ultrasonic knife handle 2 further includes a housing 20, which is wrapped around the outside of the ultrasonic vibrating plate 21 and the amplitude transformer 22, and one end of the housing 20 exposes the clamping plate 23 and the blade 24.
[0048] The aforementioned damping rubber ring 28 is disposed between the amplitude rod 22 and the outer casing 20, which can reduce the vibration of the amplitude rod 22 on the outer casing 20.
[0049] In some examples, a switch button 201 is provided on the outside of the housing 20. When the operator presses the switch button 201, the ultrasonic vibrating plate 21 generates ultrasonic energy. The ultrasonic energy is output to the blade 24 by the amplitude transformer 22, thereby performing operations such as cutting and coagulation on the contacted biological tissue.
[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
