[0087] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0088] Refer to Figures 1 to 20:

[0089] This application provides a portable ultrasonic scalpel, which is designed to be handheld and easy to carry, has a long battery life, multiple switching modes, and is equipped with a child lock.

[0090] As shown in Figures 1, 2, and 14 to 18, the portable ultrasonic scalpel of this application mainly includes a main unit 10 and a main unit battery 20. The main unit battery 20 is installed on one side of the main unit 10 through a plug-in mechanism 6. The main unit 10 includes a handheld housing 1, a switch device 2, a transducer 3, a main board 4, and a heat dissipation mechanism 5. The main board 4, the transducer 3, and the heat dissipation mechanism 5 are installed on the inner side of the main unit 10 in an order that facilitates assembly. The heat dissipation mechanism 5 includes a cooling fan 51 and a heat dissipation hole 52. The cooling fan 51 is installed on one side of the transducer 3 and can dissipate heat from the transducer 3 while exhausting hot air through the heat dissipation hole 52. The heat dissipation hole 52 is located on the side of the handheld housing 1 away from the transducer 3. The switch device 2 is installed on one side / lower end of the handheld housing 1 and is used to control the opening and closing of this ultrasonic scalpel.

[0091] It is important to understand that the working logic of the ultrasonic scalpel here is that the piezoelectric ceramic of the transducer 3 inside the host 10 is excited by the current, generating mechanical vibration, which is then transmitted to the blade 31 installed at the end of the transducer 3, forming an amplitude of more than 10,000 times per second. The high-frequency amplitude, combined with the blade 31 and its own sharpness, can achieve the effect of cutting iron like mud.

[0092] Specifically, in order to efficiently exhaust hot air, the heat dissipation mechanism 5 also includes a heat dissipation duct 53. The heat dissipation duct 53 is formed between the inner side of the handheld housing 1, the outer side of the transducer 3 and the heat dissipation fan 51. The air enters from the bottom of the host 10, passes through the duct and is then dissipated through the heat dissipation hole 52.

[0093] Specifically, referring to Figure 15, the heat dissipation duct 53 includes an inlet duct 531, a heat exchange duct 532, and an outlet duct 533. A capillary air inlet 54 is provided on the side of the transducer near the blade 31. The blade 31 is installed at the end of the transducer 3, and a shock-absorbing ring is provided at the end of the transducer 3. An annular toothed groove is provided on the inner ring of the shock-absorbing ring, forming a capillary air inlet 54 between the annular toothed groove and the end of the transducer 3. Furthermore, multiple capillary air inlets are provided, arranged around the outer periphery of the end of the transducer.

[0094] An air inlet duct 531 is formed between the capillary air inlet 54 and the transducer 3. Specifically, the air inlet duct 531 is located in the space at one end of the transducer 3 where the capillary air inlet 54 is situated. Air enters through the capillary air inlet 54, passes through the space at the end of the transducer 3, and enters the heat exchange duct 532. A large-space heat exchange duct 532 is located above the main body of the transducer 3. This heat exchange duct 532 is the main area for heat exchange or cooling. Since the main heat-generating part of the transducer 3 is located in its main body, i.e., its end, a large cavity is formed between the transducer 3 and the main body for heat exchange. Alternatively, the cooling fan 51 forms the air outlet 533. The cooling fan 51 includes an air inlet 511, a main fan 512, and an air outlet 513. The air inlet 511 is located on one side of the transducer 3, and the air outlet 513 is located on both sides of the main fan 512, which are aligned with the heat dissipation holes 52. Thus, a complete air blowing system is formed, in which air enters from the capillary air inlet 54, passes through the transducer 3, and is blown out to the heat dissipation holes 52 by the cooling fan 51. The heat dissipation holes 52 are located at the upper end of the handheld shell and will not be blocked by the palm. Preferably, the cooling fan 51 is a turbofan.

[0095] In one embodiment, as shown in Figures 2 to 13, to achieve detachable installation of the main unit battery 20 and the main unit 10, the main unit battery 20 is detachably installed on the upper end of the main unit 10 via a plug-in mechanism 6. The plug-in mechanism 6 includes a plug groove 61, a plug connector 62, a first rotation limiting protrusion 63, a first limiting slide 64, a second rotation limiting protrusion 65, and a second limiting slide 66. The upper end of the main unit 10 is recessed to form the plug groove 61, and the inner side of the plug groove 61 is provided with a first... The side wall of the contact assembly 67 and the plug groove 61 is provided with a first limiting slide 64 and a second limiting slide 66 from top to bottom. The lower end of the main battery 20 is provided with a plug 62. The plug 62 is provided with a first limiting protrusion 63 and a second limiting protrusion 65 from top to bottom. The bottom end of the plug 62 is provided with a second contact assembly 68. The first limiting protrusion slides and the first limiting slide 64 slide and limit each other, and the second limiting protrusion slides and the second limiting slide 66 slide and limit each other.

[0096] The first limiting slide 64 and the second limiting slide both extend circumferentially along the insertion groove 61. The first limiting protrusion 63, the first limiting slide 64, the second limiting protrusion 65, and the second limiting slide 66 form a rotational engagement mechanism for setting the gear position. The first contact group 67 is located on the bottom wall of the insertion groove, and the second contact group 68 is located on the bottom wall of the connector 62. The connector 62 is rotatably inserted into the insertion groove 61 via the rotational engagement mechanism. When the main unit battery 20 rotates relative to the main body 10 to the working position, the corresponding contacts of the first contact group 67 and the second contact group 68 are connected, allowing the machine to be turned on. Furthermore, the main unit battery 20 can rotate relative to the main unit 10 to contact different contacts of the first contact group 37 and the second contact group 68 to match the unlock position, charging position, and working position.

[0097] Specifically, referring to Figures 8 to 13, both the first contact group 67 and the second contact group 68 include a positive contact 671 and a negative contact 672, wherein the negative contact 672 is located in the middle or at the center, and the positive contact 671 is located outside the negative contact 672.

[0098] Specifically, the positive contact 671 includes a charging positive contact 671a and a working positive contact 671b. The charging positive contact 671a, the working positive contact 671b, and the negative contact 672 are distributed at right angles to each other. It also includes a signal contact 671c, which is located on the other side of the working positive contact 671b and is symmetrically distributed with the working positive contact 671b. It should be understood that the contacts at one end of the main battery 20 and the contacts at the main unit 10 are of the same nature. However, in order to realize the gear shifting mechanism, preferably, the charging positive contact 671a at one end of the main battery 20 is located at the top, the working positive contact 671b and the signal contact 671c are located on both sides of the negative contact 672, while the charging positive contact 671a and the working positive contact 671b at the main unit 10 are the same contact, and the signal contact 671c is located on the other side.

[0099] Furthermore, the positive contact 671, negative contact 672, and signal contact 671c of the first contact group 67 are arranged in a straight line, and the positive contact 671 and signal contact 671c of the first contact group 67 are symmetrically distributed relative to the negative contact 672; the positive contact 671 of the second contact group 68 includes a charging positive contact 671a and a working positive contact 671b, the working positive contact 671b, negative contact 672, and signal contact 671c of the second contact group 68 are arranged in a straight line, the working positive contact 671b and signal contact of the second contact group 68 are symmetrically distributed relative to the negative contact 672, and the charging positive contact 671a, working positive contact 671b, and negative contact 672 of the second contact group 68 are arranged at three right angles.

[0100] In the unlocked position, the negative contact 672 of the main battery 20 is in contact with the negative contact 672 of the main unit 20, and the other contacts are offset from each other. When switching to the charging position, the negative contact 672 of the main battery 20 is in contact with the negative contact 672 of the main unit 10, the charging positive contact 671a of the main battery 20 is in contact with the positive contact 671 of the main unit 10, and the other contacts are offset from each other, allowing the main unit 10 to charge the main battery 20. When switching to the working position, the negative contact 672 of the main battery 20 is in contact with the negative contact 672 of the main unit 10, the working positive contact 671b of the main battery 20 is in contact with the positive contact 671 of the main unit 10, and the signal contact 671c of the main battery 20 is in contact with the signal contact 671c of the main unit 10, allowing the portable ultrasonic scalpel to be turned on and put into operation.

[0101] Specifically, referring to Figures 6 and 7, the first limiting slide 64 includes a first inlet groove 641, a first concave point 642, and a second concave point 643. The first inlet groove 641 and the first concave point 642 form a first front section 64a, and the first concave point 642 and the second concave point 643 form a first rear section 64b. The arc surface of the first front section 64a forms a 45-degree angle with the axis of the insertion groove 61 (i.e., the central angle of the arc surface of the first front section 64a relative to the axis of the insertion groove 61 is 45 degrees). The first rear section 64b forms a 90-degree angle with the axis of the insertion groove 61 (i.e., the central angle of the arc surface of the first rear section 64b relative to the axis of the insertion groove 61 is 90 degrees). The second limiting slide 66 includes a second inlet groove 661 and a third concave point 66. 2 and the fourth concave point 663, wherein the second inlet groove 661 and the third concave point 662 form the second front section 66a, and the third concave point 662 and the fourth concave point 663 form the second rear section 66b. The arc surface of the second front section 66a forms a 45-degree angle with the axis of the insertion groove 61 (that is, the arc surface of the second front section 66a forms a 45-degree angle with the central angle corresponding to the axis of the insertion groove), and the second rear section 66b forms a 90-degree angle with the axis of the insertion groove 61 (that is, the arc surface of the second rear section 66b forms a 90-degree angle with the central angle corresponding to the axis of the insertion groove). The charging positive contact 671a is vertically distributed above and below the first rotation limiting protrusion 63, and when the first rotation limiting protrusion 63 enters the first inlet groove 641, the second rotation limiting protrusion 65 also enters the second inlet groove 661.

[0102] The rotation logic of the main unit battery 20 when installed on the main unit 10 is as follows, referring to Figures 11-13, taking the first protrusion and the first limiting slide 64 as an example: because the charging positive contact 671a at one end of the main unit battery 20 is vertically distributed with the first protrusion, the charging positive contact 671a at one end of the main unit battery 20 and the first protrusion are vertically overlapping. After aligning the first protrusion of the main unit battery 20 with the first inlet groove 641 and inserting it downwards, the first protrusion will then reach the first position, which is the unlock position or the first position (Figure 11). At this point, the main battery 20 can also be removed from the first position. Then, rotate the battery 45 degrees clockwise until the first protrusion reaches the first concave point 642, also known as the second position (Figure 12). At this point, because the charging positive contact 671a at one end of the main battery 20 is in contact with the charging positive contact 671a at the end of the main unit 10 (the working positive contact 671b and the charging positive contact 671a in the connector slot are at the same point), the main unit 10 can charge the main battery 20, but it cannot drive the transducer 3 and the cooling fan 51 to work. The switch 2 cannot be opened, and the main unit 10 can be charged through the charging port at one end, or it can be charged with the charging dock. When the battery is rotated 90 degrees (or 135 degrees compared to the original position), the first protrusion is disengaged from the first concave point 642 and enters the first rear section 64b position. Continue rotating until the first protrusion engages with the second concave point 643, reaching the third position (Figure 13). The working positive contact 671b at one end of the main unit battery 20 and the working positive contact 671b at the end of the main unit 10 make contact. When the positive signal contact 671 at one end contacts the positive signal contact 671 at the end of the main unit 10, and the negative contact 672 that was already in contact, all three contacts are connected at the same time. Through the program setting, the main control board controls the switch device 2 and the transducer 3 to work, thereby enabling the machine to work. That is, when the main unit battery 20 rotates 45 degrees (second position), it only charges the main unit battery 20. When the main unit battery 20 rotates 135 degrees (third position), the machine can be turned on and worked. In addition, with the marking on the upper surface of the plug slot 61, a stronger child lock function can be provided.

[0103] Specifically, in order to cater to the needs of more customers for switch preferences, the switch device 2 here includes a toggle switch 21 and a push switch 22, wherein the toggle switch 21 is used to control the operation of the ultrasonic scalpel by toggle, and the push switch 22 is used to control the operation of the ultrasonic scalpel by pressing.

[0104] Specifically, a switch rail 23 is provided on one side of the handheld housing, and an FPC button PCB board 24 is provided at the lower end of the switch rail 23. One end of the FPC button PCB board 24 is electrically connected to the main board 4, and the FPC button PCB board 24 has a toggle switch 21 and a push switch 22 as electrical keys. The switch rail 23 is provided with a rail groove 231, and the inner side of the rail groove 231 has partitioned protrusions 231a. A switch lever 25 is slidably connected to the outer side of the switch rail 23. The switch lever 25 includes a slide rail end 251 and a lever end 252, wherein the slide rail end 251 is located on the inner side and is T-shaped and is connected to the rail. The groove 231 is slidably engaged. The inner side of the slide rail end 251 is provided with a first switch groove 251a and a second switch groove 251b that can engage with the partition protrusion 231a. When the switch lever 25 is manually moved so that its first switch groove 251a engages with the partition protrusion 231a, the switch device 2 is controlled by the toggle switch 21. When the switch lever 25 is manually moved so that its second switch groove 251b engages with the partition protrusion 231a, the switch device 2 is controlled by the push switch 22. In practice, a mark is made on the lever end 252 so that the user can know which direction to move the lever to determine which switch state.

[0105] Specifically, to achieve diversified functions of the main unit 10, a main unit cover 30 is connected to the lower end of the main unit 10. A maintenance cover 310 is provided at the lower end of the main unit cover 30. The main unit cover 30 and the maintenance cover 310 are magnetically attached to each other through a magnetic attachment assembly 301. The inner side of the maintenance cover 310 is provided with a tool changing groove 311 and a tool storage hole 312. The tool changing groove 311 is used to loosen the locking screw of the transducer 3. The tool storage hole 312 stores maintenance tools. The tool changing groove 311 has a hexagonal or square groove to match the shape of the nut at the end of the transducer 3. This allows the nut fixing the blade 31 to be opened directly with the maintenance cover 310 for tool replacement, which is very convenient. After use, the maintenance cover 310 can be directly attached to the main unit cover 30, making it less likely to be lost. The aforementioned tool change slot can be configured as a tool change slot with a magnet for magnetically attracting the blade. The maintenance tool adapter is inserted into the main unit cover 30 so that the bottom wall of the main unit 10 and the top wall of the main unit cover 30 fit together.

[0106] Referring to Figures 21 to 34, this application also provides an ultrasonic scalpel device, including a charging storage base 100, a portable ultrasonic scalpel, and a backup battery 300. The portable ultrasonic scalpel includes a main unit 200 and a main unit battery 20 detachably configured in the main unit 200. The charging storage base 100 is provided with a main unit charging storage slot 110 and a battery charging storage slot 120. The main unit 200 is inserted into the main unit charging storage slot 110 and can be charged through a first charging component 40. The backup battery 300 is inserted into the battery charging storage slot 120 and can be charged through a second charging component 50. The specific structure of the portable ultrasonic scalpel is as described in the above embodiments. Since this ultrasonic scalpel device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. In addition, this ultrasonic scalpel device can specifically adopt all the technical solutions of all the embodiments of the ultrasonic scalpel device below, and therefore has all the beneficial effects brought about by the technical solutions of all the embodiments of the ultrasonic scalpel device below, which will not be described in detail here.

[0107] Ultrasonic scalpels are widely used in the cutting field. They transmit ultrasonic vibrations to the blade tip, achieving a cutting effect as sharp as cutting through iron with tens of thousands of vibrations per second combined with the cutting action of the blade. Currently, the most commonly used ultrasonic scalpels on the market are box-type and portable types. Box-type ultrasonic scalpels use a box structure with a wire connected to the blade head. A large-capacity battery is installed in the box, enabling long battery life and high power output. However, these ultrasonic scalpels are large and heavy, making them inconvenient to carry. Portable ultrasonic scalpels are small and easy to carry, but because the battery is built-in, their battery life is greatly reduced, and the output power is also limited by the battery life. If a large battery is used, it will affect its portability. The existing solution is to equip multiple spare batteries, but charging the spare batteries requires a separate charger. Therefore, how to balance portability, product storage, battery life, and charging has become one of the problems that need to be solved. In addition, the storage and disposal of the blades is also an issue that needs to be addressed. Traditional blades are stored separately in separate blade boxes, and used blades are discarded at will, which can easily lead to accidental injury.

[0108] Based on this, this application provides an ultrasonic scalpel device.

[0109] Referring to Figures 21 to 30, the ultrasonic scalpel device in this embodiment includes a charging storage base 100 for charging and storing the main unit 200 and the backup battery 300, a portable ultrasonic scalpel main unit 200, and a backup battery 300. The main unit 200 has a detachable main unit battery 20. The charging storage base 100 has a main unit charging storage slot 110 and a battery charging storage slot 120. The main unit 200 is inserted into the main unit charging storage slot 110 and can be charged via a first charging component 40. The backup battery 300 is inserted into the battery charging storage slot 120 and can be charged via a second charging component 50. Here, the main unit battery 20 and the backup battery 300 are interchangeable. When the main unit battery 20 is depleted, it is inserted into the battery charging storage slot 120 for charging. The original spare battery 300 is inserted into the main unit 200 and becomes the main unit battery 20. The main unit 200 is connected to the charging storage cradle 100, which supplies power to the main unit 200 and charges the battery. At the same time, the charging storage cradle 100 also charges the spare battery 300. In this way, one charge can provide at least two battery cycles. If charging conditions are available, the main unit 200 can be removed and cut while the spare battery 300 is charged, which can extend the battery life. When carrying it out, the charging storage cradle 100 also becomes a storage cradle or base for the main unit 200 and the spare battery 300, so there is no need to make additional packaging for the main unit 200 or the spare battery 300. Therefore, it is very convenient to use.

[0110] Specifically, as shown in Figures 22 to 24 and Figures 27 to 30, the first charging assembly 40 includes a first charging pin 41 and a first charging contact 42. A main control board 102 is located inside the charging storage base 100. A charging main board 103 is located at the upper end of the main control board 102. The first charging pin 41 extends upward from the charging main board 103 and passes through the host charging storage slot 110. The lower end of the host 200 is provided with the first charging contact 42. When the host 200 is inserted into the host charging storage slot 110, the first charging contact 42 engages with the first charging pin 41. The main unit 200 is charged by contacting the electrical pin 41. The second charging component 50 includes a second charging pin 51 and a second charging contact 52. The upper side of the charging motherboard 103 is also provided with a second charging pin 51. The lower end of the backup battery 300 is provided with a second charging contact 52. When the backup battery 300 is inserted into the battery charging storage slot 120, the second charging contact 52 contacts the second charging pin 51 to charge the backup battery 300. The charging motherboard 103 is electrically connected to the main control board 102. Preferably, the charging motherboard 103 is a pogo-pin board.

[0111] Specifically, referring to Figures 22 to 24 and Figure 30, the main unit 200 has a first handheld part 210 and a first plug-in part 220. The upper end of the first handheld part 210 is provided with the main unit battery 20, and the lower end of the first handheld part 210 is provided with the first plug-in part 220. The shape of the first plug-in part 220 matches that of the main unit charging storage slot 110. Preferably, the first plug-in part and the charging storage slot are rounded rectangular shapes, which allows for quick alignment and insertion. A first positioning block 221 is provided on one side of the first plug-in part 220, and the inner side of the main unit charging storage slot 110 corresponds to the first positioning block 221. The position of block 221 is provided with a first positioning groove 111. The spare battery 300 has a second hand-held part 320 and a plug 62. The lower end of the second hand-held part 320 is provided with the plug 62. A first rotation limiting protrusion is provided on one side of the plug 62. The battery charging storage slot 120 is provided with a second positioning groove 121 corresponding to the position of the first rotation limiting protrusion. Preferably, the second positioning groove 121 is a vertical slot. The first rotation limiting protrusion can be inserted downward along the vertical slot, so that the second charging pin 51 is aligned and contacted with the second charging contact 52, and ensures that no deflection occurs during the charging process.

[0112] Furthermore, a blade receiving groove 130 is provided on the bottom wall of the main unit charging storage tank 110. The cross-sectional area of ​​the blade receiving groove 130 is smaller than that of the main unit charging storage tank 110. The blade 31 of the main unit 10 and the end of the transducer 3 are inserted into the blade receiving groove 120.

[0113] To address the issues of retrieving and storing the blades 68, please refer to Figures 21, 25, 26, and 31 to 34. A blade box 60 is also designed here. The blade box 60 is detachably connected to one side of the charging storage base 100. This detachability is achieved using methods such as magnetic attraction or snap-fit. The blade box 60 includes a housing 600. A first storage cavity 6A and a second storage cavity 6B are provided within the blade box 60 / housing 600. The first storage cavity 6A is used to store blades 68 to be used, and the second storage cavity 6B is used to store discarded blades 68. A retrieval slot 610 communicating with the first storage cavity 6A is provided on one side, and a discard slot 620 communicating with the second storage cavity 6B is provided on one side.

[0114] Specifically, as shown in Figures 31 to 24, a spring assembly 630 is provided at the bottom inner side of the first storage cavity 6A. A blade holder 640 is provided at the upper end of the spring assembly 630. An inner groove 6410 is provided at the bottom of the blade holder 640. The spring assembly 630 is composed of several springs, which are arranged in the internal spring channel or sleeved on the spring post 631. The spring post 631 is embedded in the inner groove 6410. Alternatively, the blade holder 640 is longitudinally arranged through a limiting channel to prevent it from deviating to the left or right, ensuring that the holder always pushes upward. The blade 68 is located at the upper end of the blade holder 640, and the blade 68 is supported upward by the blade holder 640, so that a part of the blade 68 is always exposed on one side of the retrieval groove 610. When the knife needs to be removed, press the topmost blade 68 with your finger and use the downward friction to slide the blade 68 outward. Once it reaches the outermost edge, the blade 68 can be removed. Specifically, the retrieval groove 610 has an inner limiting end face 611 and an outer limiting end face 612. The horizontal height of the inner limiting end face 611 is higher than that of the outer limiting end face 612. In this way, when the topmost blade 68 slides outward, it will not directly pierce the other end of the retrieval groove 610, but can slide outward along the other end. In order to make the blade 68 slide out at an angle for easy finger retrieval, the outer side of the retrieval groove 610 is provided with a sliding ramp 613 for the blade 68 to slide outward at an angle.

[0115] In a preferred embodiment, the blade holder 640 has a beveled surface that causes the upper blade 68 to tilt outward toward the take-up slot 610, making it easier to take up the blade 68.

[0116] Specifically, the outer side of the retrieval slot 610 is also provided with a transition slot 650, and a magnetic suction component 651 is provided on the transition slot 650. The magnetic suction component 651 is used to attract and pull when retrieving the blade 68 or to temporarily attract the blade 68 when replacing the blade 68. The principle is that when the blade 68 is slid outward by the finger and forms a slightly raised angle along the inclined surface 613, the outer end of the blade 68 just slides above the magnetic suction component 651. The magnetic suction component 651 attracts the outer end of the blade 68 downward, thereby giving the blade 68 a traction force, allowing the blade 68 to be taken out more quickly.

[0117] Specifically, referring to Figures 26, 31 to 33, one side of the charging storage base 100 is provided with a plug-in female component 71, and one side of the blade box 60 is provided with a plug-in male component 72 that is plugged into and engaged with the plug-in female component 71. The blade box 60 and the charging storage base 100, as well as adjacent blade boxes 60, are detachably connected via the plug-in male component 72 and the plug-in female component 71. On the opposite side of the blade box 60, a plug-in female component 71 is provided that is plugged into and engaged with the plug-in male component 72. Thus, one side of the blade box 60 is detachably connected to the charging storage base 100 via the plug-in male component 72 and the plug-in female component 71, and the other side of the blade box 60 is detachably connected to adjacent blade boxes 60 via the plug-in male component 72 and the plug-in female component 71.

[0118] Specifically, the male plug-in component 72 includes a passageway portion 721 and an embedded portion 722 that are perpendicular to each other. The passageway portion 721 is connected to the main body of the blade box 60, and the embedded portion 722 is located outside the passageway portion 721. The female plug-in component 71 includes a passageway groove 711 and an embedded groove 712 that are interconnected. The passageway groove 711 is slotted outward, and the embedded groove 712 is slotted downward. When the male plug-in component 72 is inserted into the female plug-in component 71 from the bottom upward, the passageway portion 721 is just locked in the passageway groove 711, and the embedded portion 722 is just locked in the embedded groove 712.

[0119] As an optional embodiment, as shown in FIG22, a charging indicator light 104 is also provided on one side of the charging storage base 100. The charging indicator light 104 includes a main unit 200 charging indicator light 104 and a backup battery 300 charging indicator light 104. The charging of the main unit 200 and the backup battery 300 are indicated by different indicator lights to facilitate observation of the charging status. In addition, in this ultrasonic device, both the charging storage base 100 and the main unit 200 are equipped with charging sockets, which facilitate charging the main unit battery 200 through the main unit 200 alone, or charging the main unit battery 200 by inserting the main unit 200 into the charging storage base 100. The charging storage 100 can charge the main unit battery 20 and store the main unit 200. In addition, as a subsequent improved embodiment, the charging storage 100 is also equipped with a backup power source, which is equivalent to a second backup battery 300. This allows the charging storage 100 to charge the main unit 200 or the backup battery 300 independently when there is no charging, achieving three or even more battery lifespans. Here, battery lifespan refers to the battery life of the main unit 200 powered by a single battery. Under rechargeable conditions, through fast charging and battery swapping, near-unlimited battery life can be achieved, thus solving the battery life anxiety of traditional ultrasonic scalpels.

[0120] As an optional embodiment, please refer to FIG23, a counterweight component 105 is provided on the inner side of the charging storage base 100. The counterweight component 105 is preferably a counterweight iron to help the charging storage base 100 have a stable center of gravity and resist the lateral tilting force of the elongated main unit 200 above.

[0121] Compared with traditional ultrasonic scalpel devices, the ultrasonic scalpel device of this application has a longer battery life, is more portable, and is easier to store and charge. At the same time, the blade 68 is easy to handle and the waste blade 68 can be recycled in an environmentally friendly manner.

[0122] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
