The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0027] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] In order to make the technical personnel in this field better understand the present application scheme, the following Figures 1-8 , clearly and completely describe the technical solutions in the embodiments of this application.

[0029] As attached Figure 1 -Attached Figure 8 As shown, the present application provides an ultrasonic bone knife handle, comprising: a shell 1 and a tail cover 2 arranged on the shell 1, the ultrasonic bone knife handle also includes a limiting connecting block 3, the tail cover 2 is detachably connected to the shell 1 through the limiting connecting block 3, and a snap structure 100 is provided on the limiting connecting block 3, and the snap structure 100 is respectively engaged with the shell 1 and the tail cover 2 to limit the axial movement of the shell 1 and the tail cover 2.

[0030] The limiting connecting block 3 of the present application is respectively engaged with the shell 1 and the tail cover 2 through the snap structure 100, so that the shell 1 and the tail cover 2 are detachably connected together through the limiting connecting block 3. Compared with the fixing method by glue injection in the prior art, the snap connection fixing method of the present application is firmly fixed, and no additional control is required on the shell 1 and the tail cover 2 during fixation, so that the tail cover 2 can be fixed on the shell 1 to ensure that the shell is neat. At the same time, the detachable connection fixing method can remove the tail cover 2 or the limiting connecting block 3 in time when the tail cover 2 or the limiting connecting block 3 becomes loose and reinstall it, which is convenient for rework and facilitates the later maintenance of the ultrasonic bone knife handle, reducing rework and maintenance costs.

[0031] As attached Figure 1 -Attached Figure 8 As shown, the buckle structure 100 further includes a first buckle 31 and a second buckle 32. The housing 1 is provided with a first latch 11 adapted to the first buckle 31, and the tail cover 2 is provided with a second latch 21 adapted to the second buckle 32. The housing 1 and the position-limiting connecting block 3 are connected by the engagement of the first buckle 31 with the first latch 11, and the tail cover 2 and the position-limiting connecting block 3 are connected by the engagement of the second buckle 32 with the second latch 21. This fixing method of the buckle and the latch is convenient for installation and disassembly, does not require other locking accessories, is low in cost, and meets the design requirements of the ultrasonic osteotome handle.

[0032] As attached Figure 1 -Attached Figure 8As shown, further, a first notch 111 is provided between the two first latching positions 11 for the first latch 31 to pass through during axial assembly, and a slot 34 is provided on the first latch 31 for the first latching position 11 to engage during rotational engagement. The position-limiting connecting block 3 is fixed to the housing 1 by rotational engagement. The rotational engagement method makes the assembly and disassembly process very fast and convenient, does not require additional fasteners, has a compact structure, reduces the space required for fasteners, and has good reusability. At the same time, the rotational engagement method is highly reliable, provides a stable connection, and can withstand the vibration of the transducer.

[0033] As attached Figure 1 -Attached Figure 8 As shown, further, the second snap 32 is an elastic snap, which is deformed by pressure and resets to engage with the second latch 21. The tail cover 2 is fixed to the limit connection block 3 by the elastic snap. When the tail cover 2 is pressed to move toward the limit connection block 3, the second latch 21 squeezes the second snap 32 so that the second snap 32 is compressed and deformed inwardly. When the second snap 32 passes the second latch 21, the pressure disappears and the second snap 32 is reset, so that the second snap 32 and the second latch 21 are engaged with each other, limiting the axial movement of the tail cover 2. The assembly and disassembly process becomes very fast and convenient, without the need for additional fasteners, the structure is compact, and the space required for fasteners is reduced. Compared with the rotational engagement method, the elastic snap simplifies the design.

[0034] As attached Figure 1 -Attached Figure 2 and attached Figure 4 -Attached Figure 5 As shown, the ultrasonic osteotome handle further includes a transducer assembly 4 disposed within the housing 1. A wiring harness 41 is connected to the transducer assembly 4. The position-limiting connection block 3 further includes a third notch 33 for the wiring harness 41 to engage. This prevents the housing 1 and the inner wall of the tail cover 2 from squeezing the wiring harness 41 during connection. The third notch 33 ensures that the wiring harness 41 has ample space to pass through without being squeezed, thereby protecting the wiring harness 41, extending its service life, and ensuring the integrity and stability of power supply and signal transmission.

[0035] As attached Figure 1 -Attached Figure 2 and attached Figure 4 -Attached Figure 5As shown, the limiting connecting block 3 is further provided with a connecting portion 35 connected to the transducer assembly 4. The snap-fit structure 100 is provided on the outer circumferential surface of the connecting portion 35. One end of the connecting portion 35 is provided with a connecting cavity 351 for partially inserting the transducer assembly 4. The connecting cavity 351 is a blind hole, which facilitates connection with the transducer assembly 4 and limiting the position of the transducer assembly 4, thereby improving the stability of the connection.

[0036] As attached Figure 1 -Attached Figure 2 and attached Figure 4 -Attached Figure 5 As shown, further, the transducer assembly 4 is provided with a nut 5 and a buffer washer 6, one end of the buffer washer 6 abuts against the nut 5, and the other end of the buffer washer 6 abuts against the inner wall of the connecting cavity 351. The nut 5 is threadedly connected to the transducer assembly 4, and the end of the nut 5 away from the transducer assembly 4 abuts against the inner wall of the connecting cavity 351 through the buffer washer 6, so that the inner wall of the connecting cavity 351 can provide the transducer assembly 4 with a position limit for the nut 5 toward the transducer assembly 4. At the same time, the buffer washer 6 can prevent energy loss, so that the energy of the transducer assembly 4 can act on the bone cutter as a whole.

[0037] As attached Figure 1 -Attached Figure 2 and attached Figure 4 -Attached Figure 5 As shown, the other end of the connecting portion 35 is connected to a water pipe 7, and the transducer assembly 4 is provided with a water inlet 43 inserted into the connecting cavity 351 and communicating with the water pipe 7. The water inlet 43 and the connecting cavity 351 are plug-fitted together, which is easy and fast to install, improves work efficiency, and facilitates maintenance and replacement without the need for additional fasteners. The position-limiting connecting block 3 is engaged with the housing 1 to limit the position of the water inlet 43 and the connecting cavity 351.

[0038] As attached Figure 1 -Attached Figure 2 and attached Figure 4 -Attached Figure 5 As shown, further, a sealing groove 44 is formed on the water inlet 43, and a sealing ring 8 is disposed in the sealing groove 44. The sealing groove 44 provides a suitable installation position for the sealing ring 8, so that it can better exert its sealing function and ensure the sealed connection between the water inlet 43 and the connecting cavity 351.

[0039] As attached Figure 1 -Attached Figure 2 and attached Figure 7As shown, further, the tail cover 2 is provided with an installation cavity 22 with both ends being open, and the water pipe 7 passes through the installation cavity 22 and is exposed outside the ultrasonic osteotome handle. The water pipe 7 is used to connect to an external water source to provide water for the transducer assembly 4.

[0040] Furthermore, the water pipe 7 is made of metal, which improves the strength and durability of the water pipe 7.

[0041] Furthermore, the front end of the shell 1 is also connected to a front cover 91 and an LED light assembly 92. The front cover 91 is threadedly connected to the shell 1. The LED light assembly 92 can provide a light source during treatment, thereby improving the convenience of using the ultrasonic bone knife.

[0042] During installation, install the LED lamp assembly 92 on the housing 1 and screw in the front cover 91, then install the transducer assembly 4 into the housing 1, tidy up the wiring harness 41, align the first buckle 31 with the first notch 111 and push the limiting connection block 3 forward to insert it into the housing 1, and snap the wiring harness 41 into the third notch 33, then rotate the limiting connection block 3 to a certain angle so that the limiting connection block 3 is rotationally engaged with the handle housing 3, that is, the first clamping position 11 is screwed into the slot 34, and finally the The tail cover 2 is inserted into the limiting connecting block 3. When the tail cover 2 is pressed to move it toward the limiting connecting block 3, the second clamping position 21 squeezes the second buckle 32 so that the second buckle 32 is compressed and bends inward. When the second buckle 32 passes the second clamping position 21, the pressure disappears and the second buckle 32 is reset. At this time, a sound of the second buckle 32 resetting can be heard, so that the second buckle 32 and the second clamping position 21 are engaged with each other, so that the tail cover 2 is connected to the limiting connecting block 3, and the assembly is completed.

[0043] Based on the above-mentioned ultrasonic bone knife handle, the present application also provides an ultrasonic bone knife device, including the ultrasonic bone knife handle, the limiting connecting block 3 is respectively engaged with the shell 1 and the tail cover 2 through the snap structure 100, so that the shell 1 and the tail cover 2 are detachably connected together through the limiting connecting block 3. Compared with the fixing method of the prior art by injection of glue, the snap connection fixing method of the present application is firmly fixed, and no additional control is required on the shell 1 and the tail cover 2 during fixation, so that the tail cover 2 can be fixed on the shell 1 to ensure that the shell is neat. At the same time, the detachable connection fixing method, when the tail cover 2 or the limiting connecting block 3 becomes loose, the tail cover 2 or the limiting connecting block 3 can be removed and reinstalled in time, which is convenient for rework and facilitates the later maintenance of the ultrasonic bone knife handle, reducing rework and maintenance costs.
