Description

Technical Field

[0001] The utility model relates to the technical field of skin stretching devices, in particular to a skin stretching device with negative pressure suction. Background Art

[0002] A skin stretching device is a device that closes cracked skin or wounds to help patients with larger wounds heal, or to assist doctors in suturing larger wounds.

[0003] At present, most skin stretching devices close the cracked wound by clamping or threading when in use, but the contact part with the skin is generally in the shape of a sharp hook, which may cause puncture injury to the skin when clamping the patient's skin. In addition, the clamping angle of the existing skin stretching device cannot be adjusted when in use, and cannot be adjusted accordingly according to the different wound conditions of different patients, and the structure is rigid.

[0004] The Chinese utility model patent with the current announcement number: CN215503215U discloses a skin stretching device with negative pressure suction. The negative pressure docking tube is set in conjunction with the negative pressure suction hole and the clamping hook, so that when the device clamps the patient's skin, the patient's skin can be adsorbed through the negative pressure suction hole, making the clamping more stable and without causing puncture damage to the patient's skin. At the same time, the rotating rod is set in conjunction with the first threaded rod and the second threaded rod, so that when the device is in use, the clamping angle and the upper and lower distances can be better adjusted, so that the device can better adapt to different patients, solving the problem that traditional skin stretching devices may cause puncture damage to the patient's skin when used, and the structure is relatively rigid and cannot be adjusted at multiple angles.

[0005] In view of the above problems, the existing patent provides a solution, but the second threaded rod is rotated to rotate the clamp to fix the adjusting rod. This method is not as reliable as adjusting the height of the support rod to adapt to the position of the patient's wound. Since the adjusting rod is not fixed, there is a great possibility of uncertainty when negative pressure suction is performed on the patient's wound.

[0006] For this purpose, a skin stretching device with negative pressure suction is proposed. Utility Model Content

Rotating the threaded rod 602 can drive the cross plate 1 to rotate, so that the angle of the negative pressure suction component 4 can be adjusted to meet the needs of wounds in different positions of the patient. At this time, the adjustment plate 3 moves along the trajectory of the moving groove 502 through the moving block 501, and The moving block 501 will drive the threaded column 504 to move along the trajectory of the through groove 503. When the distance between the adjustment plate 3 and the support plate 2 reaches the required specified position, the hand-tightening nut 505 on the outer periphery of the threaded column 504 is tightened so that one end of the hand-tightening nut 505 is tightly pressed against the side wall of the horizontal plate 1. By adjusting the distance between the support plate 2 and the adjustment plate 3, the negative pressure suction component 4 can be used to meet the needs of wounds of different areas.
