[0023] A method for using a skin burn skin grafting and plastic surgery auxiliary device comprises the following steps:

[0024] S1. When in use, the operator holds the handle frame and moves the auxiliary bracket to the position of the skin to be transplanted, and supports the auxiliary bracket on the patient's body surface through the pads on both sides of the auxiliary bracket. Then the operator uses the thumb to move the adjustment ring on the surface of the auxiliary bracket, so that the adjustment ring brings the transmission gear rod to mesh with the threaded gear rod, and then the threaded gear rod drives the circular gear and the corresponding transmission screw to rotate. Under the cooperation of the U-shaped sleeve and the U-shaped insert strip between the two transmission screws, the two transmission screws rotate synchronously. At this time, the thread sleeve on the surface of the transmission screw drives the corresponding main winding roller to translate at the side wall position of the auxiliary bracket, and synchronously adjust the distance between the two main winding rollers;

[0025] S2. When the two main winding rollers are adjusted to the positions on both sides of the skin to be transplanted, the operator pulls the pull ring rod with the middle finger, so that the pull ring rod brings the pressure plate to fit toward the inner wall of the auxiliary bracket. At this time, the pressure plate brings the connecting telescopic rod and the pull rod to move synchronously, so that the pull rod pulls the corresponding U-shaped adjustment sleeve to translate inside the main winding roller. At the same time, under the cooperation of the four hinged rods of the diamond structure and the adjustment rod, the U-shaped adjustment sleeve inside the slave winding roller translates in the opposite direction. During the translation of the U-shaped adjustment sleeve, the L-shaped adjustment groove and the adjustment pin cooperate to slide and extend the needle inside the sink groove, so that the needle penetrates into the skin. The two main winding rollers and the two slave winding rollers cooperate to position the skin on all sides.

[0026] S3, as the pull rod continues to move with the U-shaped adjustment sleeve, the adjustment rod continues to move toward the inside of the secondary winding roller and is pressed against the secondary winding roller by the corresponding U-shaped adjustment sleeve. At this time, the secondary winding roller and the main winding roller move away from each other for a short distance, tightening the longitudinal position of the positioned skin. At the same time, the pressure plate pulls the cone plate with the connected telescopic rod to move between the two cone sleeves, so that the side walls of the two cone sleeves are compressed. Then, the two transmission screws move away from each other with the corresponding main winding rollers, tightening the transverse position of the positioned skin.

[0027] S4, then turn the adjustment ring to make the two transmission screws rotate synchronously and move the two main winding rollers synchronously relative to each other. During the translation of the main winding rollers, the synchronous gears on the surfaces of the main winding rollers mesh with the synchronous racks on the inner walls of the transmission grooves, so that the two main winding rollers rotate synchronously in opposite directions to rewind the stretched skin, and then transfer the skin to the burn position. Finally, turn the adjustment ring in the opposite direction to make the two main winding tubes rotate in the opposite direction and translate, unfold the rolled skin, and apply it to the burn position. After the skin is applied, release the pull ring rod, and the compression spring resets the pressure plate, so that the pull rod resets the U-shaped adjustment sleeve, and the needle is automatically retracted into the sink, so that the auxiliary bracket can be separated from the skin.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] In the present invention, through the coordinated use of components such as an auxiliary bracket, an adjustment mechanism and a transfer mechanism, by turning the adjustment ring on the adjustment mechanism, the adjustment mechanism leads the two main winding rollers on the transfer mechanism to move in opposite directions, and then the pull ring rod is pulled to make the needle extend from the corresponding main winding roller and from the inside of the winding roller to position the skin to be transplanted. Then, the two main winding rollers move relative to each other and rotate to wind up the skin, and then move to the patient's burn position. After the adjustment ring is rotated in the opposite direction to unfold the skin, it can be quickly applied to the burn position, which is convenient to use.

[0030] In the present invention, through the coordinated use of components such as the auxiliary bracket, the transfer mechanism and the pull ring rod, after the needles on the two main winding rollers and the slave winding roller have positioned the skin to be transplanted, the pull ring rod is continued to be pulled so that the two main winding rollers and the slave winding roller can be fine-tuned in opposite directions, thereby tightening the positioned skin to avoid wrinkles and improving the flatness of the skin during the later application to the burn position.

[0031] In the present invention, by using the handle frame, the transmission gear rod and the adjustment ring and other components in coordination, the two transmission screws can be rotated synchronously by turning any adjustment ring, so that the operator can operate the auxiliary device with both hands according to the surgical habits, thereby improving the convenience of use.

[0061] In this embodiment, Figures 1 to 8 As shown, a method for using a skin burn skin grafting and plastic surgery auxiliary device comprises the following steps:

[0062] S1. During use, the operator holds the handle frame 710 and moves the auxiliary support 1 to the position of the skin to be transplanted, and supports the auxiliary support 1 on the patient's body surface through the pads 3 on both sides of the auxiliary support 1. Then, the operator uses the thumb to move the adjustment ring 714 on the surface of the auxiliary support 1, so that the adjustment ring 714 brings the transmission gear rod 713 to mesh with the threaded gear rod 716, and then the threaded gear rod 716 drives the circular gear 715 to rotate with the corresponding transmission screw 6. Under the cooperation of the U-shaped insert 703 and the U-shaped insert strip 704 between the two transmission screws 6, the two transmission screws 6 rotate synchronously. At this time, the screw sleeve 705 on the surface of the transmission screw 6 drives the corresponding main winding roller 9 to translate at the side wall position of the auxiliary support 1, and synchronously adjusts the distance between the two main winding rollers 9.

[0063] S2. When the two main winding rollers 9 are adjusted to the positions on both sides of the skin to be transplanted, the operator pulls the pull ring rod 711 with the middle finger, so that the pull ring rod 711 brings the pressure plate 707 to fit toward the inner wall direction of the auxiliary bracket 1. At this time, the pressure plate 707 brings the connecting telescopic rod 708 and the pull rod 1003 to move synchronously, so that the pull rod 1003 pulls the corresponding U-shaped adjustment sleeve 1007 to translate inside the main winding roller 9. At the same time, under the cooperation of the four hinged rods 1014 of the diamond structure and the adjustment rod 1006, the U-shaped adjustment sleeve 1007 inside the slave winding roller 1005 translates in the opposite direction. During the translation of the U-shaped adjustment sleeve 1007, the L-shaped adjustment groove 1008 cooperates with the adjustment pin 1009 to slide and extend the needle 1011 inside the sink groove 1010, so that the needle 1011 penetrates into the skin.
