    摘要: A stabilizer is provided to secure and fix the position of a cannula assembly relative to tissue. The stabilizer is a liquid swellable member which expands within an incision in tissue in response to the absorption of a liquid. The stabilizer includes an inner adhesive layer to secure the stabilizer relative to a cannula assembly. The stabilizer is formed of a polymeric gel or foam. In one embodiment, the stabilizer is fixedly secured to an elongate tubular member of a cannula assembly. In an alternative embodiment, the stabilizer is mounted for longitudinal movement along an elongate tubular member of a cannula assembly.

    摘要: A cannula assembly includes a cannula adapted for insertion within tissue and having a longitudinal passage extending along a longitudinal axis of the cannula for passage of a surgical instrument. An expandable member is mounted to the cannula and longitudinally spaced from a distal end of the cannula. The expandable member is adapted to expand, upon introduction of fluids therein, in a radially outward direction relative to the longitudinal axis whereby the expandable member engages the tissue to facilitate anchoring of the cannula relative to the tissue, and also to expand in a radially inward direction relative to the longitudinal axis and within the longitudinal passage to engage the surgical instrument positioned within the longitudinal passage to facilitate formation of a seal about the surgical instrument.

    摘要: A soluble needle (100) for hair transplantation, wherein the soluble needle (100) comprises a fixing plate (30) and a plurality of micro-needles (20) made of water-soluble polymers arranged on the fixing plate (30), wherein each of said micro-needle (20) comprises a needle wall (21) to penetrate scalps and a needle cavity (22) confined by the needle wall (21) and configured for accommodating a hair follicle. A method of manufacturing a soluble needle (100) for hair transplantation, wherein the method includes: dissolving water-soluble polymers in water to prepare a molding solution (S101); delivering the molding solution into a mold (S102); letting the molding solution settle in the mold to shape (S103); and separating and removing the mold to produce the soluble needle (S104). The soluble needle (100) effectively shortens the time of surgery, reduces the pain of the patients, and increases the viability rate of transplanted hair follicles.
