When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0040] During plastic surgery, a medical handpiece drives the blade body to move accordingly, performing procedures such as sawing or cutting bone tissue. In existing technologies, the connection between the blade body and the handpiece is weak, causing the blade body to vibrate during surgery, which can lead to serious medical accidents.

[0041] In order to solve the above technical problems, the present invention proposes a blade mounting structure.

[0042] See also Figure 1-4 In one embodiment of the present invention, the blade mounting structure is applied to a medical plastic surgery mobile phone 100; the blade mounting structure is used to mount a blade body 200 to the medical plastic surgery mobile phone 100, wherein the blade body 200 includes a blade portion 210 and a cylindrical handle portion 220;

[0043] Specifically, the blade mounting structure includes:

[0044] The shaft tube 300 is installed. The interior of the shaft tube 300 is provided with a mounting cavity 310. The mounting cavity 310 is used to sleeve the handle portion 220. The inner side wall of the mounting cavity 310 is in contact with the outer side surface of the handle portion 220 to limit the radial movement of the handle portion 220.

[0045] Among them, a limit piece 230 is provided at the end of the handle part 220 away from the blade part 210, and a notch portion 240 is provided at the connection between the limit piece 230 and the handle part 220; the blade mounting structure also includes a first positioning block 320 and a second positioning block 330; the first positioning block 320 is fixedly arranged in the mounting cavity 310, and the first positioning block 320 is used to be embedded in the notch portion 240 to limit the axial movement of the handle part 220; the second positioning block 330 is slidably connected to the mounting cavity 310, and the second positioning block 330 is used to abut the side of the limit piece 230 to limit the circumferential movement of the handle part 220.

[0046] The technical solution of the present invention is to set the shank portion 220 into a cylindrical structure. When the shank portion 220 is sleeved on the mounting cavity 310, the inner side wall of the mounting cavity 310 and the outer side surface of the shank portion 220 are in contact with each other, so as to achieve the purpose of limiting the radial movement of the shank portion 220; at the same time, a first positioning block 320 and a second positioning block 330 are provided inside the mounting cavity 310. After the shank portion 220 is installed in the mounting cavity 310, on the one hand, the first positioning block 320 is embedded in the notch portion 240. At this time, the two sides of the first positioning block 320 respectively abut against the ends of the shank portion 220 and the limiting member 230 on the opposite side, so that the blade body 200 cannot move axially under the restriction of the first positioning block 320; on the other hand, the second positioning block 330 slides until it abuts against the side of the limiting member 230. Due to the obstruction of the second positioning block 330, the limiting member 230 cannot rotate along the axis of the shank portion 220, that is, the circumferential movement of the shank portion 220 is limited. In summary, the radial movement, axial movement and circumferential movement of the handle portion 220 are all restricted, so that the blade body 200 cannot be displaced relative to the mounting shaft tube 300, thereby improving the connection strength between the blade body 200 and the medical plastic surgery mobile phone 100, to ensure that the blade body 200 does not deviate from vibration during the operation.

[0047] Furthermore, a preset gap 380 is defined between the first positioning block 320 and the mounting cavity 310. The cross-sectional area of ​​the preset gap 380 is greater than that of the stopper 230, but smaller than that of the handle 220. This arrangement allows the preset gap 380 to pass through, but prevents the handle 220 from passing through. After the stopper 230 passes through the preset gap 380, the blade body 200 is rotated a certain angle, allowing the notch 240 of the stopper 230 to engage with the first positioning block 320, thereby achieving the purpose of limiting the axial movement of the handle 220 by the first positioning block 320.

[0048] As a preferred solution of the above embodiment, refer to the attached Figure 1-4The mounting structure also includes a sliding ring 340 that is slidably sleeved on the mounting shaft tube 300. A sliding groove 350 is opened on the side of the mounting shaft tube 300, and the groove direction of the sliding groove 350 is arranged along the axial direction of the mounting shaft tube 300; a connecting pin 360 is slidably connected in the sliding groove 350, and the sliding ring 340 is fixedly connected to the second positioning block 330 through the connecting pin 360; a first spring 370 is provided in the mounting cavity 310, and the first spring 370 is arranged between the second positioning block 330 and the inner bottom of the mounting cavity 310. When the handle 220 is inserted into the mounting cavity 310, the limiting member 230 passes through the preset gap 380 and abuts against the end of the second positioning block 330; as the handle 220 continues to be inserted, the limiting member 230 drives the second positioning block 330 to move toward the inner bottom direction of the mounting cavity 310, during which the second positioning block 330 compresses the first spring 370; when the blade body 200 is rotated to a certain angle so that the notch 240 of the limiting member 230 and the first positioning block 320 are interlocked, the limiting member 230 is rotated to the point where it does not abut against the end of the second positioning block 330, and the second positioning block 330 is missing the limiting member 230. 30 abuts, thereby driving the second positioning block 330 to move toward the shank portion 220 under the elastic force of the second spring, so that the side of the second positioning block 330 abuts against the limiting member 230; since the second positioning block 330 is connected to the sliding ring 340 through the connecting pin 360, and the connecting pin 360 is restricted from sliding in the sliding groove 350 of the mounting shaft tube 300, the movement trajectory of the second positioning block 330 can only move along the axial direction of the mounting shaft tube 300, and cannot move circumferentially; thereby, the limiting member 230 abutted by the second positioning block 330 cannot move circumferentially, so as to achieve the purpose of limiting the circumferential movement of the shank portion 220.

[0049] Furthermore, two connecting pins 360 are symmetrically arranged on opposite sides of the second positioning block 330, and the sliding grooves 350 correspond one-to-one with the connecting pins 360. This arrangement ensures that when the sliding ring 340 slides on the second positioning block 330 via the connecting pins 360, the forces on the opposite sides of the second positioning block 330 are balanced, which helps to improve the smoothness of the sliding of the second positioning block 330.

[0050] As an alternative to the connecting pin, in another embodiment, the blade mounting structure can be designed to include a connecting bolt and a connecting nut. The connecting bolt passes through the sliding groove, the sliding ring, and the second positioning block in sequence before being threadedly connected to the connecting nut. In this arrangement, the combination of the connecting bolt and the connecting nut allows the sliding ring and the second positioning block to be combined to form a single unit, capable of sliding along the sliding groove. It will be appreciated that through-holes for the connecting bolt are provided in the sliding ring and the second positioning block to ensure that the connecting bolt can smoothly pass through the dynamic ring and the second positioning block.

[0051] As a preferred solution of the above embodiment, refer to the attached Figure 1-4 The mounting structure further includes a push sleeve assembly 400, which is used for the operator to slide the sliding ring 340. This arrangement takes into account that when replacing the blade body 200, it is necessary to first release the restriction of the second positioning block 330 on the limiter 230, so that the shank portion 220 can rotate circumferentially until its limiter 230 is aligned with the preset gap 380, so that the limiter 230 can pass through the preset gap 380 and thus remove the shank portion 220 from the mounting shaft tube 300. Therefore, the operator needs to slide the sliding ring 340 to move the second positioning member toward the inner bottom of the mounting cavity 310, thereby releasing the restriction of the second positioning block 330 on the limiter 230. In order to facilitate the operator's sliding operation on the sliding ring 340, this embodiment provides a push sleeve assembly 400 on the mounting structure.

[0052] Specifically, the push sleeve assembly 400 includes a guide sleeve 410 that is slidably mounted on the mounting shaft tube 300, and a push sleeve 420 that is slidably mounted on the first end of the guide sleeve 410. At least a portion of the push sleeve 420 is exposed to the outside of the medical plastic surgery mobile phone 100, and the guide sleeve 410 is fixedly connected to the medical plastic surgery mobile phone 100; a guide groove 411 is provided on the side of the guide sleeve 410, and the groove direction of the guide groove 411 is arranged along the axial direction of the mounting shaft tube 300; a push pin 430 is slidably connected in the guide groove 411, one end of the push pin 430 is fixedly connected to the push sleeve 420, and the other end of the push pin 430 abuts against the end of the sliding ring 340 away from the second spring. With this arrangement, at least a portion of the push sleeve 420 in this embodiment is exposed outside the handle body. An operator slides the push sleeve 420 through the exposed portion, causing it to move toward the inner bottom of the mounting cavity 310. Because the push sleeve 420 is connected to a push pin 430, during movement, the push pin 430 pushes the sliding ring 340 toward the inner bottom of the mounting cavity 310, thereby releasing the second positioning block 330 from the restraint on the limiter 230. Furthermore, because the push pin 430 is constrained to slide within the guide groove 411 of the guide sleeve 410, and the guide groove 411 is axially disposed along the mounting shaft tube 300, the push sleeve 420 can only move axially along the mounting shaft tube 300 when pushed by the operator, thereby improving the guiding performance of the push sleeve 420 during movement.

[0053] Furthermore, a protrusion 412 is provided at the second end of the guide sleeve 410, and a second spring 440 is sleeved on the guide sleeve 410. The second spring 440 is disposed between the push sleeve 420 and the protrusion 412. With this arrangement, when the push sleeve 420 pushes the sliding ring 340, the push sleeve 420 compresses the second spring 440. When the blade body 200 and the medical plastic surgery handpiece 100 are separated, the operator releases the force applied to the push sleeve 420, and the push sleeve 420 returns to its original position under the elastic force of the second spring 440.

[0054] Furthermore, two push pins 430 are symmetrically arranged on opposite sides of the push sleeve 420, and the sliding grooves 350 correspond one to one with the connecting pins 360. This arrangement ensures that when the push sleeve 420 pushes the sliding ring 340 via the push pins 430, the forces on both sides of the sliding ring 340 are balanced, which helps to improve the smoothness of the sliding ring 340 during sliding.

[0055] Furthermore, the exposed area of ​​the push member 420 is provided with anti-skid lines 421. Such arrangement increases the friction between the operator and the push member 420 through the anti-skid lines 421, thereby facilitating the operator to push the push member 420.

[0056] The following describes the disassembly and assembly process of the blade body 200 and the handle body in detail in combination with the above embodiment:

[0057] When installing the blade body 200:

[0058] Step 1: Refer to the attached Figure 5 The handle portion 220 of the blade body 200 is inserted into the mounting cavity 310 of the mounting shaft tube 300 located inside the medical plastic surgery mobile phone 100. Since the inner side surface of the mounting cavity 310 and the outer side surface of the handle portion 220 are in contact with each other, the radial movement of the handle portion 220 is restricted. At this time, the limiting member 230 of the handle portion 220 is aligned with the preset gap 380 between the first positioning block 320 and the mounting cavity 310.

[0059] Step ②: Refer to the attached Figure 6 As the shank portion 220 continues to be inserted, its limiting member 230 passes through the preset gap 380 until the first positioning block 320 and the end of the shank portion 220 abut against each other; during this period, the limiting member 230 abuts against the end of the second positioning block 330 after passing through the preset gap 380, and as the shank portion 220 continues to be inserted, the limiting member 230 drives the second positioning block 330 to move toward the inner bottom of the installation cavity 310, during which the second positioning block 330 compresses the first spring 370;

[0060] Step 3: Refer to the attached Figure 7-8The blade body 200 is rotated by a certain angle. On the one hand, the notch portion 240 of the limiting member 230 is engaged with the first positioning block 320 to limit the axial movement of the handle portion 220; on the other hand, the limiting member 230 is rotated until it does not abut against the end of the second positioning block 330, and the second positioning block 330, due to the lack of abutment of the limiting member 230, moves toward the handle portion 220 under the elastic force of the first spring 370, so that the side of the second positioning block 330 abuts against the limiting member 230; since the second positioning block 330 cannot move circumferentially, the circumferential movement of the handle portion 220 is limited; thereby, the installation operation of the blade body 200 is completed.

[0061] When the blade body 200 is disassembled:

[0062] Step 4: Push the push sleeve 420, and use the push sleeve 420 to push the sliding ring 340 toward the inner bottom of the installation cavity 310 via the push pin 430. The sliding ring 340 and the second positioning block 330 are connected to each other via the connecting pin 360, so that the second positioning block 330 also moves toward the inner bottom of the installation cavity 310 synchronously, thereby releasing the restriction on the limiting member 230 by the second positioning block 330, that is, the second positioning block 330 releases the restriction on the circumferential movement of the blade body 200;

[0063] Step 5: The blade body 200 is circumferentially moved until the limiting member 230 is aligned with the preset gap 380. At this time, the notch portion 240 is released from the mutual engagement with the first positioning block 320, that is, the first positioning block 320 releases the restriction on the axial movement of the blade body 200.

[0064] Step ⑥: Pull the shank portion 220 out of the mounting shaft tube 300. At this time, the limit member 230 can pass through the preset gap 380 until the shank portion 220 and the mounting shaft tube 300 are separated from each other, thereby completing the disassembly operation of the blade body 200; then the push sleeve 420 is reset under the elastic force of the second spring 440, and at the same time, the second positioning block 330 is also reset under the elastic force of the first spring 370.

[0065] This embodiment also discloses a medical plastic surgery handpiece 100, which includes a blade mounting structure according to any of the aforementioned embodiments.

[0073] Example 2:

[0074] Reference Attachment Figure 12-14 In this embodiment, the blade body 200 is selected as an oscillating saw, that is, when the blade body 200 performs reciprocating oscillating motion around its own axis in the circumferential direction:

[0075] The transmission structure 500 includes a second eccentric assembly 530 and a second gear assembly 540. The second eccentric assembly 530 includes a swinging member 531 and a second eccentric wheel member 532. The central axis and the rotation axis of the second eccentric wheel member 532 are located on non-colinear lines. The swinging member 531 is provided with a swinging groove 533 with an inwardly concave setting. The groove direction of the swinging groove 533 is arranged along the radial direction of the mounting shaft tube 300. The second eccentric wheel member 532 is arranged in the swinging groove 533, wherein the swinging groove 533 is provided with a second eccentric wheel member 532 for receiving the second eccentric wheel member 532. The second eccentric wheel member 532 has a movable space for reciprocating eccentric rotation, and at least part of the outer surface of the second eccentric wheel member 532 is in contact with the inner wall of the swing groove 533; the rotation drive device can drive the second eccentric wheel member 532 to perform reciprocating eccentric rotation through the second gear assembly 540; the mounting shaft tube 300 is rotatably connected to the interior of the medical plastic surgery mobile phone 100, the first end of the mounting shaft tube 300 is connected to the handle portion 220, and the second end of the mounting shaft tube 300 is fixedly connected to the swing member 531.

[0076] In this way, when the blade body 200 performs reciprocating swinging motion around its own axis in the circumferential direction, the transmission structure 500 is configured to include a second eccentric assembly 530 and a second gear assembly 540, wherein the second eccentric assembly 530 includes a swinging member 531 and a second eccentric wheel member 532, and the central axis and the rotation axis of the second eccentric wheel member 532 are located on non-coaxial lines; when the rotary drive device drives the second eccentric wheel member 532 to perform reciprocating eccentric rotational motion through the second gear assembly 540, at least part of the outer side of the second eccentric wheel member 532 is rotated. The surface of the second eccentric wheel 532 maintains contact with the inner sidewall of the swing groove 533, and the mounting shaft tube 300 is rotatably connected to the interior of the medical plastic surgery handpiece 100. This allows the swing member 531 to only perform reciprocating swinging motion around the axis of the mounting shaft tube 300, under the dual constraints of the second eccentric wheel 532 and the mounting shaft tube 300, thereby driving the mounting shaft tube 300 to perform reciprocating swinging motion around its own axis. Furthermore, because the mounting shaft tube 300 is connected to the handle portion 220, the blade body 200 is driven to perform reciprocating swinging motion around its own axis. Furthermore, the swing groove 533 of the transmission structure 500 is provided with a movable space for the reciprocating eccentric rotation of the second eccentric wheel 532. This movable space also serves as an adjustment space for the relative position of the second eccentric wheel 532 and the swing member 531, thereby enabling small adjustments within the transmission structure 500 to reduce the risk of the oscillating saw from jamming during operation, thereby improving the smoothness of the surgical process and preventing medical accidents.

[0077] It can be understood that the driving mode of the above-mentioned rotation driving device is to rotate back and forth in a manner of alternating clockwise rotation and counterclockwise rotation, so as to achieve the purpose of driving the blade body 200 to perform reciprocating swinging motion.

[0078] Furthermore, the second eccentric assembly 530 also includes a second eccentric shaft 534 and a second bearing seat (not shown in the drawings). The first end of the second eccentric shaft 534 is connected to the second eccentric member 532, which is then mounted within the second bearing seat. The second eccentric shaft 534 is rotationally connected to the medical plastic surgery handpiece 100 via the second bearing seat. This arrangement, in which the second eccentric shaft 534 is rotationally connected to the medical plastic surgery handpiece 100 via the second bearing seat, allows the second eccentric member 532, connected to the second eccentric shaft 534, to smoothly perform reciprocating eccentric rotational motion relative to the medical plastic surgery handpiece 100, thereby ensuring the smooth implementation of the technical solution of this application.

[0079] Furthermore, the second gear assembly 540 includes an outer gear 541 and an inner gear ring 542. The outer gear 541 is located inside the annular ring of the inner gear ring 542, and the outer gear 541 and the inner gear ring 542 mesh with each other for transmission. The outer gear 541 is connected to the driving end of the rotary drive device, and the inner gear ring 542 is fixedly connected to the second end of the second eccentric shaft 534 via a connecting plate 543. In this arrangement, the outer gear 541 and the inner gear ring 542 are combined to form the second gear assembly 540, which reduces the speed of the rotary drive device to a speed that meets the rotary drive force required for plastic surgery. The connecting plate 543 then drives the second eccentric shaft 534 to reciprocate, and the second eccentric shaft 534 then drives the second eccentric member 532 to perform reciprocating eccentric rotation. This embodiment has a simple structure and is highly practical.
