The utility model belongs to the medical instrument field suitable for orthopedics operation, concretely relates to a multipurpose periosteal distraction device, at least includes: the periosteal distraction board is the strip board that presents the arc shape bending in the length direction, one end of periosteal distraction board is provided with locking hole, the bone needle has the needle head of inserting on the skeleton in one end, is equipped with the limit snap ring in the other end, the distraction nail is equipped with the through cavity that penetrates the distraction nail along the length direction inside, the distraction nail is divided into the nail head and the threaded rod that is screwed with locking hole, the distraction nail is screwed with periosteal distraction board, the bone needle is inserted in the through cavity, the limit snap ring is located nail head side, the needle head protrudes distraction nail outside. The utility model's periosteal distraction device can solve the technical defects of the periosteal distraction board of prior art because of stripping incision bilateral periosteum and big trauma, poor applicability when skull periosteum is distracted and bone needle inserts too deep.

The present invention relates to an exosome-stabilized skin-improving cosmetic composition comprising a vitamin complex, which can improve the structural stability of exosomes. The composition comprises bone spicule, lactic acid bacteria exosome, and ceramide in a weight ratio of 0.6:3.0:0.01, the lactic acid bacteria exosome comprising a substance obtained by culturing Lactobacillus curvatus GFC-AM5 strain (deposited number KCCM12245P) at 37°C for 20 hours and concentrating it by 40 times or more. In addition, by including a vitamin complex of two or more selected from the group consisting of vitamin C or a derivative thereof, vitamin E or a derivative thereof, nicotinamide, and panthenol, oxidation of the lipid bilayer of the exosome can be inhibited, and the increase in particle size during storage can be reduced. Thereby, the structural integrity of the exosome can be maintained, thereby preserving the cell signaling function for a long time, and the stabilized exosome is delivered to the inside of the skin through the microchannels formed by the bone spicule, thereby effectively exerting a skin-improving effect.

This utility model relates to a metal bone needle with an openable hole and a chip-dispersing groove, comprising a metal bone needle body and an opening / closing spring. The metal bone needle body includes a cylindrical needle body and a needle tip. A threading notch or two threading notches are provided on the side of the needle body near the needle tip. An upper arc-shaped groove and a lower arc-shaped groove are respectively provided at both ends of the threading notch. A baffle is provided at the edge of the upper arc-shaped groove, and a connecting hole is provided in the lower arc-shaped groove. The opening / closing spring includes an opening / closing piece, an arc-shaped piece, and a connecting piece. One end of the arc-shaped piece is connected to the opening / closing piece, and the other end of the arc-shaped piece is connected to the connecting piece. The arc-shaped piece engages in the lower arc-shaped groove, the connecting piece is inserted into the connecting hole, and the other end of the opening / closing piece presses against the inner side of the baffle in the upper arc-shaped groove. Three or four edges are evenly distributed on the side of the needle tip, and chip-dispersing grooves are provided between adjacent edges. The advantage is that it solves the technical problem that existing needle holes cannot be opened, making it difficult to insert double-stranded sutures.

This utility model belongs to the field of surgical reference frame technology and discloses a omnidirectional connection and fastening device for a surgical reference frame. A hinge ball connects to a bone needle, one end of a locking screw is hinged to the hinge ball, a clamping block is fitted onto the locking screw, the reference frame is rotatably connected to the clamping block, and a locking nut is screwed to the other end of the locking screw and fixes the clamping block. The omnidirectional adjustment of the reference frame is achieved by setting three rotational degrees of freedom. The locking screw is also fitted with a toothed slider, one side of which has a ball socket. The hinge ball is rotatably positioned in the ball socket. The hinge ball has an arc-shaped external toothed ring, and the ball socket has an arc-shaped internal toothed ring that meshes with the arc-shaped external toothed ring to prevent the toothed slider from causing the locking screw to rotate relative to the hinge ball. A first toothed ring is located on the side of the toothed slider away from the ball socket, and a second toothed ring that meshes with the first toothed ring on the clamping block to prevent the clamping block from rotating relative to the toothed slider. This effectively prevents the reference frame from loosening and ensures its stability.
