Description

Technical Field

[0001] The utility model specifically relates to a rotary skin flap auxiliary design plan line measuring ruler. Background Art

[0002] At present, in skin repair surgery, the rotation flap repair method is often used to repair circular skin defects. Compared with the traditional diamond flap or Z flap, the rotation flap repair method has the characteristics of less rotation tension and less damage to the tissue around the flap.

[0003] In the rotational flap repair method, it is necessary to make a wound tangent perpendicular to the minimum tension line RSTL determined at the defect site, and the length of the wound tangent is 1.5 times the diameter of the wound. Then, an incision with an angle of 60° is made along the end of the wound tangent, and the wound is repaired by rotating the flap. Then, an incision with an angle of 45° is made at the other end of the wound tangent to form a triangular flap repair donor area. At this time, a marking measuring ruler is required to assist in the marking operation. Most existing marking measuring rulers have a simple structure, and the ruler body needs to be continuously adjusted to control the marking angle when marking. It is more troublesome to use and reduces the efficiency of marking. Therefore, in view of the above technical problems, a rotational flap auxiliary design marking measuring ruler is proposed.

[0030] See also Figure 1 , Figure 2 In one embodiment, a rotational flap auxiliary design plan line measuring ruler includes a main ruler 10, a first secondary ruler 20, a second secondary ruler 30 and an adjustment component 40.

[0031] The first secondary ruler 20 is located at one side of the main ruler 10, and one end is connected to one end of the main ruler 10, and the angle between the first secondary ruler 20 and the main ruler 10 is 45°. Specifically, two groups of first open bayonet pins 201 are oppositely arranged at one end of the first secondary ruler 20, and two groups of first bayonet pin holes 101 are oppositely opened at one end of the main ruler 10, and the two groups of first open bayonet pins 201 can be clamped in the two groups of first bayonet pin holes 101.

[0032] In the above embodiment, the first secondary ruler 20 is connected to the main ruler 10 by snap-fitting, so that the first secondary ruler 20 can be easily carried after being disassembled, and the first secondary ruler 20 can be prevented from being squeezed and deformed during carrying, and the angle between the first secondary ruler 20 and the main ruler 10 can be prevented from changing.

[0033] See also Figures 1 to 3 In one embodiment, the second secondary ruler 30 is located at the other side of the main ruler 10. The adjustment assembly 40 includes a guide seat 401 and a fixing bolt 402. The guide seat 401 can be slidably arranged on the main ruler 10 along the length direction of the main ruler 10. Specifically, two groups of first guide grooves 102 are relatively opened on the main ruler 10, and two groups of first guide blocks 4011 are relatively arranged on the guide seat 401.

[0037] See also Figure 3 In one embodiment, the adjustment assembly 40 also includes a mounting seat 403 and a driving member; the mounting seat 403 can be slidably set on the guide seat 401 along the length direction of the main ruler 10, the driving member can be rotatably set on the guide seat 401 and connected to the mounting seat 403, the rotating driving member can drive the mounting seat 403 to slide, and one end of the second secondary ruler 30 is set on the mounting seat 403.

[0038] Specifically, the driving member includes an adjusting screw 404; a second guide groove 4012 is opened on the guide seat 401, and a second guide block 4031 is arranged on the mounting seat 403. The second guide block 4031 can be slidably arranged in the second guide groove 4012 along the length direction of the main ruler 10, and the adjusting screw 404 can be rotatably arranged in the second guide groove 4012 and is threadedly connected with the second guide block 4031.

[0039] In the above embodiment, the second guide block 4031 can be driven to move by rotating the adjusting screw 404 in coordination with the second guide block 4031, and the movement of the second guide block 4031 can drive the mounting seat 403 to move, and the movement of the mounting seat 403 can drive the second secondary ruler 30 to move, and the second guide block 4031 can be fixed by stopping the rotation of the adjusting screw 404, so that the second secondary ruler 30 can be fixed at any position. The movement and fixation of the second secondary ruler 30 are convenient, and the position of the second secondary ruler 30 can be fine-tuned, thereby improving the accuracy of subsequent marking.

[0040] On the basis of the above embodiment, further, two groups of second open bayonet pins 4032 are arranged on the mounting seat 403, and two groups of second bayonet pin holes 301 are opened on one end of the second secondary ruler 30, and the two groups of second open bayonet pins 4032 can be clamped in the two groups of second bayonet pin holes 301.

[0042] The specific implementation of the above rotation flap auxiliary design plan line measuring ruler is as follows:

[0043] First, the fixing bolt 402 is rotated to separate the fixing bolt 402 from the main scale 10, and then the guide seat 401 is moved along the main scale 10. The guide seat 401 moves through the mounting seat 403 to drive the second sub-scale 30 to move, so as to quickly adjust the position of the second sub-scale 30. When the second sub-scale 30 moves to the approximate position, the fixing bolt 402 is rotated in the opposite direction to make the fixing bolt 402 contact with the main scale 10, so as to fix the guide seat 401. Then, the second guide block 4031 can be driven to move by rotating the adjusting screw 404 to cooperate with the second guide block 4031. The movement of the second guide block 4031 can drive the mounting seat 403 to move. The movement of the mounting seat 403 can drive the second sub-scale 30 to move. When the second sub-rule 30 moves so that the distance between the ends of the first sub-rule 20 and the second sub-rule 30 along the main ruler 10 is 1.5 times the diameter of the wound surface, the second sub-rule 30 can be fixed by stopping rotating the adjusting screw 404. The position of the second sub-rule 30 can be adjusted quickly and accurately by moving the guide seat 401 and rotating the adjusting screw 404, thereby improving the subsequent marking accuracy. After the position of the second sub-rule 30 is adjusted, the main ruler 10 is moved so that the main ruler 10 is perpendicular to the minimum tension line RSTL of the wound surface, and a tangent matching the wound surface can be drawn along the first sub-rule 20, the main ruler 10 and the second sub-rule 30. There is no need to adjust the main ruler 10 during the marking process, which is convenient and labor-saving to use and improves the marking efficiency.

[0044] At the same time, the first secondary ruler 20 and the second secondary ruler 30 are both connected to the main ruler 10 by snap-fitting, so as to facilitate carrying of the device after the first secondary ruler 20 and the second secondary ruler 30 are disassembled, thereby preventing the first secondary ruler 20 and the second secondary ruler 30 from being squeezed and deformed during carrying, and preventing the angle between the first secondary ruler 20 and the second secondary ruler 30 and the main ruler 10 from changing.
