Technical Field
[0001] This utility model relates to the field of pedicled flap repair instruments, specifically a traction fixation device for pedicled flap repair. Background Technology
[0002] A pedicled flap is a surgical procedure that preserves the blood supply to the base of the tissue before transplanting it to the defect site. The pedicled flap is typically connected to the donor site via a pedicle to maintain blood supply, while the affected area is partially separated from the donor site. The flap is usually mobile and can be transplanted from one part of the body to another. During the transfer, the bases of two flaps are connected, and the blood vessels anastomose after transplantation, resulting in better skin grafting outcomes. It is a type of reconstructive plastic surgery, most commonly seen in burn and plastic surgery, including procedures for repairing the arm and other areas.
[0003] In addition, during the repair of the pedicled flap of the arm, after the repair surgery is completed, in order to avoid the tearing of the wound during the postoperative recovery process, it is necessary to use a corresponding traction and fixation device. Furthermore, the size of the traction and fixation arm varies from patient to patient due to the different arm thicknesses, so it is necessary to make corresponding adjustments according to the arm thickness.

[0026] This utility model provides the following technical solution:
[0027] Example 1
[0028] Combination Figures 2 to 6A traction and fixation device for pedicled flap repair includes a base 1, a locking mechanism 2 fixedly connected inside the base 1, and a locking mechanism 3 fixedly connected to the surface of the locking mechanism 2.
[0029] The locking mechanism 2 includes a rotating rod 21, which is fixedly connected to the inside of the base 1. An arc-shaped fixing plate 22 is rotatably connected to the surface of the rotating rod 21. An arc guide seat 23 is fixedly connected to the surface of the arc guide seat 22. An arc-shaped strip 24 is slidably connected inside the arc guide seat 23. A top seat 25 is fixedly connected to the top of the arc-shaped fixing plate 22. There are two arc-shaped strips 24. A support seat 26 is fixedly connected to the top of the left arc-shaped strip 24, and a mounting seat 29 is fixedly connected to the top of the right arc-shaped strip 24. A first spring 261 is fixedly connected to the front and rear ends of the support seat 26. A T-shaped rod 262 is fixedly connected to one end of the first spring 261. A T-shaped block 27 is fixedly connected to one end of the T-shaped rod 262. A slanted locking block 28 is fixedly connected to one end of the T-shaped block 27. A limiting cavity is opened inside the support seat 26. The surface of the T-shaped block 27 is slidably connected to the inside of the limiting cavity. A T-shaped slot is opened inside one end of the mounting seat 29. The surface of the slanted locking block 28 matches the inside of the T-shaped slot.
[0030] Furthermore, an opening is made inside the top seat 25, and the surface of the arc-shaped strip 24 is located inside the opening. The arc-shaped pad 291 is put on the arm, and then the support seat 26 is pushed so that the inclined locking block 28 inside it is inserted into the mounting seat 29. Under the elastic support of the first spring 261, the inclined locking block 28 is engaged with the inside of the mounting seat 29. At this time, the arc-shaped pad 291 just covers the arm, thereby protecting the skin near the wound on the arm and preventing the skin wound from being torn.
[0031] Example 2
[0032] See Figure 1-6 Furthermore, based on Embodiment 1, the positioning mechanism 3 further includes a positioning arc strip 31, which is fixedly connected to the side of the arc guide seat 23. A support plate 32 is fixedly connected to the bottom end of the arc strip 24. A second spring 33 is fixedly connected to both ends of one side of the support plate 32. A pull bar 34 is fixedly connected to one end of the second spring 33. A locking rod 35 is fixedly connected to both ends of one side of the pull bar 34. The surface of the locking rod 35 is slidably connected to the inside of the support plate 32. A positioning hole is opened on the surface of the positioning arc strip 31, and the surface of the locking rod 35 matches the inside of the positioning hole.
[0033] Furthermore, a limiting cavity two is opened inside the arc guide seat 23, and the surface of the support plate 32 is slidably connected to the inside of the limiting cavity two. When the pull bar 34 is pulled open and the locking rod 35 is moved inside the support plate 32, the locking rod 35 is disengaged from the locking position inside the positioning arc bar 31, thereby adjusting the position of the support plate 32 inside the arc guide seat 23, thereby changing the position of the arc bar 24. The arc bar 24 can be adjusted according to the thickness of the arm, and after the adjustment is completed, the locking rod 35 can be locked into the positioning arc bar 31.
[0034] In actual operation, when this device is used to repair pedicled flaps of the arm, it is used to fix the skin around the wound and prevent the skin wound from tearing. At this time, the arc-shaped pad 291 is put on the arm, and then the support seat 26 is pushed so that the inclined block 28 inside it is inserted into the mounting seat 29. Under the elastic support of the first spring 261, the inclined block 28 is engaged with the inside of the mounting seat 29. At this time, the arc-shaped pad 291 just covers the arm, which can protect the skin near the wound of the arm and thus prevent the skin wound from tearing.
[0035] Furthermore, when skin fixation is performed, and the thickness of the retrograde arm needs to be adjusted, the pull bar 34 is pulled open and the locking rod 35 moves inside the support plate 32, causing the locking rod 35 to disengage from the locking position inside the positioning arc strip 31. This allows the position of the support plate 32 inside the arc guide seat 23 to be adjusted, thereby changing the position of the arc strip 24. The arc strip 24 can be adjusted according to the thickness of the arm. After adjustment, the locking rod 35 can be locked back into the positioning arc strip 31.
