Detailed Description
Preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While the preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein.
Referring to fig. 1 to 5, the bearded needle pull rod type skin stretching closer according to the present invention includes: one side of the pull rod 5 is provided with a tooth socket; the middle of each joint is provided with a through hole 7, the pull rod 5 penetrates through the through holes 7 in the middle of the two joints, one joint 3 is positioned at the starting end of the pull rod 5, and the other joint 4 is positioned on the tooth groove of the pull rod 5; the buckle 6 is fixedly arranged above the joint and is movably matched with the tooth groove on one side of the pull rod 5; two groups of crochet hooks are respectively and fixedly connected below the two connectors, the hook directions of the two groups of crochet hooks are opposite, referring to fig. 1, one group of crochet hooks 1 is connected below the connector 3, and one group of crochet hooks 2 is connected below the connector 4.
In the bearded needle pull rod type skin stretching closer, the buckle 6 can be lifted or fallen, when the buckle is lifted, the pull rod 5 penetrating through the through hole 7 in the middle of the joint can realize drawing movement, when the buckle 6 falls, the buckle is tightly clamped with the tooth socket on one side of the pull rod 5, and the pull rod 5 is fixed. The pull rod can be pulled and fixed by the aid of the buckles matched with the tooth grooves, and the pull rod can be pulled reversibly because the buckles can be lifted up or fall down. The invention adopts the pull rod, the buckle and the crochet hook to draw the skin of the wound, the tension force can be conveniently adjusted and can be reversibly adjusted, the invention can adapt to the irregular wound of a plane and a non-plane, has small wound to the skin and smaller volume, does not influence the postoperative activity of a patient, and has very convenient operation and low price.
