  • Publication number: 20220000471
    Abstract: Provided are a one-way lifting embedded thread, a lifting device and a plastic surgery method using the same. The one-way lifting embedded thread includes a pulling thread and at least one cam body sleeved on the pulling thread. Two ends of the pulling thread are a lifting end and a free end. The free end is provided with an anchor structure for securing the pulling thread. Two sides of the cam body are a large end face and a small end face. The large end face of the cam body faces the free end of the pulling thread. As for the one-way lifting embedded thread, the arrangement of the anchor structure secures the one-way lifting embedded thread to the skin tissue temporarily and prevents the lifting embedded thread from completely slipping into the skin tissue.

  • Publication number: 20210393256
    Abstract: Provided are a suture, a suturing apparatus and applications thereof. The suture includes an elongated body, a first cam assembly and a second cam assembly both sleeved on the elongated body. The elongated body includes a first free end and a second free end. The first cam assembly and the second cam assembly each include at least one cam. The small end of the cam of the first cam assembly faces the first free end of the elongated body and the small end of the cam of the second cam assembly faces the second free end of the elongated body. A cross-sectional area of the small end of the cam is less than a cross-sectional area of the large end of the cam. A wall thickness of the cam tapers along a direction from the small end to the large end.

  • Publication number: 20190328659
    Abstract: An elastic sheet for re-activating an endometrial basal layer in a uterine cavity comprises a silicone rubber and a drug, wherein the drug is encased inside the silicone rubber in the manner of a drug storage zone, or uniformly dispersed inside the silicone rubber, or carried by an outer surface of the silicone rubber as a coating, and the drug comprises an estrogen. A method for forming the elastic sheet with a drug in a matrix-type elastic sheet; or as a sustained release coating is provided. The estrogen is loaded on the silicone rubber, and thus the endometrial basal layer is continuously activated through drug stimulation, allowing for the endometrial basal layer to re-proliferate the functional layers, thereby restoring the normal endometrial structure and completely preventing adhesions.
