Abstract

The invention relates to a skin pulling system and a skin pulling device. When the skin pulling device is used, a winding roller is rotated to wind a pulling wire on the winding roller, the winding roller is in a locking position, locking is achieved through matching of a turn-stopping structure and a matching strucutre, thus the winding roller is prevented from returning, when the pulling wire isneeded to be loosened, the winding roller is pushed along the winding roller, thus the winding roller moves to an unlocking position from the locking position, in this way, the turn-stopping structure and the matching structure are separated from being matched, the winding roller is in a free state, the pulling wire loosens and is separated from the winding roller under the action of opposite acting force, thus loosening of the pulling wire is achieved. According to the skin pulling device, when unlocking and locking are conducted, the winding roller is only needed to be axially moved, operation on other parts is not needed, and operation is convenient in use.

Description

technical field [0001] The invention relates to a skin pulling system and a skin pulling device thereof. Background technique [0002] When the skin tissue is damaged, the skin needs to be stretched with the help of special medical equipment, so that the damaged skin can grow under the action of tension until the wound is healed. A skin retractor is an instrument that can achieve this function. For example, the Chinese patent document with the application publication number CN109480942A discloses a skin retractor. In this skin retractor, two steel needles are worn on both sides of the wound. At the same time, the two steel needles are passed through the pull wire to apply a pulling force to the two steel needles. The free end of the pull wire is wound on the winding roller of the puller, and the pull wire is wound on the winding roller by rotating the winding roller. The length on the roller is used to adjust the pulling force of the pull wire. The pull wire is small in siz...
