Examples
Referring to fig. 1 to 3, the skin stretching closer comprises a base body 3, a compression device 1, a retraction mechanism and a needle clip. The muscle pressing device 1 is arranged on the matrix 3 and is used for pressing the muscles in the wound surface, so that the phenomenon that the wound surface is healed due to the overflow of the muscle protrusions is avoided. And the compression device 1 is adjustable along the axial direction relative to the matrix 3, and the compression device 1 is positioned at a proper position according to the condition of wound surface.
The contraction mechanism comprises a pair of connecting rods 2 respectively hinged on opposite sides of a base body 3, and an adjusting piece 5 connected with the pair of connecting rods 2, wherein the adjusting piece 5 is used for expanding or contracting the pair of connecting rods 2, and a needle is clamped at the tail end of the connecting rods 2. The distance between the two needle clamps can be adjusted according to the size of the wound surface through the functions of expanding and furling of the contraction structure, so that healing of the wound surface is better assisted. For example, when the patient applies the closer for the first time, the needle clamps at the two ends of the contraction mechanism are arranged at proper positions according to the size of the wound surface of the patient, and then the contraction mechanism is adjusted daily or for a certain period according to the healing condition of the patient, so that the healing of the patient is better assisted.
The myopic device 1 comprises a myopic plate 12 and a first screw 11, wherein the myopic plate 12 is arranged at one end of the first screw 11, and the myopic plate 12 adopts a round plate block, so that the myopic plate can be pressed against muscles in a wound surface with a larger area, and protruding overflow of the muscles is avoided. The base body 3 is provided with a threaded hole, the first screw 11 penetrates through the threaded hole of the base body 3 to form threaded connection with the base body 3, so that the screw can be axially adjusted relative to the base body 3, and the position of the myopressing plate 12 can be adjusted in a wound surface condition adapting mode.
The compression device 1 is provided with a through hole in the axial direction for setting the bone needle X passing through the first screw 11 and the compression plate 12. When the bone needle X is used, the bone needle X is fixed on the bone through the muscle, so that the closer can be better fixed on the wound surface, and the situation that the closer falls off or the wound surface is pulled due to the movement of a patient is reduced.
Preferably, one end of the adjusting member 5 is provided on one link 2, and the second screw 51 of the adjusting member 5 is screw-coupled to the other link 2. The head 52 of the adjusting piece 5 is arranged on one connecting rod 2, the distance between the two connecting rods 2 is adjusted through the threaded connection relation between the second screw rod 51 of the adjusting piece 5 and the other connecting rod 2, and the adjusting piece 5 with the structure is more convenient and rapid in unilateral adjustment. For example, the needle clip at one end is fixed and the rotation adjuster 5 pulls one of the links 2 closer or farther relative to the other link 2. The connecting rod 2 is provided with a connecting piece 4 for connecting with the adjusting piece 5, preferably, the connecting rod 2 is provided with a connecting part 21 connected with the connecting piece 4, and the connecting piece 4 is detachably inserted on the connecting rod 2.
