Description

Automatic closing device for skin wound

Technical Field

The utility model belongs to the field of medical supplies, concretely relates to automatic closer of skin wound.

Background

The skin stretching closer is a medical device which is applied to transform a wound surface from high tension closure to low tension closure through a dynamic principle, and helps the closure and the rehabilitation of a skin wound by temporarily and gradually tensioning skin tissues. The skin stretching closer is used in the wound closing period or the initial stitch removing period and plays a reinforcing role like a skin zipper. The needle-thread wound healing ointment is beneficial to wound healing, effectively avoids the defects that the traditional needle-thread suture skin wound is easy to cause new skin wound, thread allergy, foreign body residue, easy infection, centipede foot-like scars left by the healing wound and the like, and is widely used for treating various skin injuries.

Chinese patent CN1524507 discloses a skin wound closure device, which comprises two strip-shaped supporting belts and a base belt, wherein the two strip-shaped supporting belts and the base belt are respectively arranged along two sides of a skin wound, the base belt is arranged on the upper surface of the strip-shaped supporting belt, and one or more pairs of locking devices connected with the base belt are arranged on the base belt. However, when a doctor uses the closer, the wound is sealed in the whole process, the operation and the adjustment are difficult, the whole suturing process can be completed only by other auxiliary tools, and the suturing force applied to the wound can be arbitrarily increased or reduced, so that excessive adjustment force or insufficient adjustment force can be caused.

Chinese patent CN201683935U also discloses a skin stretching closer, which has two supporting structures with the same structure, and a lock catch is arranged at the end of the supporting structure, and the skin on both sides of the wound is tensioned by a ratchet strip passing through the two lock catches. However, the right-angled saw teeth on the ratchets of the skin stretching closer are two right-angled saw teeth facing different directions, that is, when the skin stretching closer is tensioned, one end of each ratchets needs to be connected to the latch of one of the support structures, the other end of each ratchets needs to be connected to the latch of the other support structure, then the ratchets are tensioned in different directions, and finally the effect of tensioning the skin is achieved.
