The invention discloses a single-crystal magnesium alloy wire for acupoint catgut embedding and weight losing and a preparation method of the single-crystal magnesium alloy wire, the chemical composition expression of the single-crystal magnesium alloy wire is Mg-yM-zR, in the formula, y and z represent the mass fraction of M and the mass fraction of R in magnesium alloy respectively, y is larger than or equal to 1.2 and smaller than or equal to 1.7, z is larger than or equal to 0.3 and smaller than or equal to 0.8, and the balance is Mg; m is one of Sr, Ce and Co, and R is one of Ge, Sm and Dy; the wire is prepared through the processes of smelting and casting, homogenizing treatment, hot extrusion, multi-pass cold drawing, intermediate annealing and zone smelting and directional solidification, and has uniform and controllable degradation rate, excellent mechanical property and biocompatibility; after the catgut embedding slimming agent is embedded into the acupuncture point of a human body, fat metabolism is promoted through mild and lasting physical stimulation and chemical ion regulation, intergranular corrosion and premature fracture caused by a polycrystalline structure are avoided, and the safety and durability of a catgut embedding slimming therapy are improved.

A biopsy gun capable of simultaneously forming a hemostatic hydrogel within the puncture channel after biopsy sampling is disclosed. The gun comprises a cannula that is ejectibly mounted to the gun body, multiple powder storage chambers arranged around a central through-hole, each with a puncture-proof bottom at the end furthest from the gun body. Two types of hydrogel precursor powders capable of cross-linking with bodily fluids are alternately placed in the powder storage chambers. A needle core is ejectibly mounted to the gun body and passes through the central through-hole, with a sampling groove at the end furthest from the gun body. Multiple needles connected to the proximal end of the needle core are inserted into the powder storage chambers in an L-shape. A medical silicone plug is fitted onto the needle, forming a sealed environment with the powder storage chambers. Upon activation, the needle core ejects first, and the needles, along with the silicone plug, puncture the bottom of the powder storage chambers, generating a pulsed pressure that releases the two precursor powders into the wound. The cannula ejects later to cut the tissue and complete the sampling. After sampling, the needle core and cannula are withdrawn, and the hydrogel precursor powders absorb blood from the wound, forming a hydrogel in situ to fill the wound.

The application discloses a kind of high expansion cellulose sponge with arch layer structure and its preparation method and application.The method is: with carboxymethyl cellulose and cellulose or its micro-nano fiber as raw material, crosslinking agent is added to prepare hydrogel.Subsequently, the sponge sample is obtained by two-way freezing of hydrogel-freeze drying, the sponge sample is soaked in the solution that can be reacted with carboxyl, the solution includes at least one of calcium chloride solution, chitosan solution or the mixed solution of two, finally, the sponge is obtained by secondary freeze-drying.The sponge of the application has good biocompatibility, high liquid absorption rate, and the volume expansion ratio can reach 10-15 times;after compression, it is used for bleeding site, can swell rapidly, block wound, and quickly stop bleeding.The sponge of the application has arch layer structure between layers, can realize high compression, and can provide expansion support force for more than 4 hours.The sponge prepared by the application can be used for deep bleeding, such as deep and narrow penetrating wound bleeding, human interface bleeding, etc.

The present invention provides a series of new percutaneous concepts of paravalvular repairs including identifying the leak location, several repair techniques and finally built-in means for leak prevention, built on percutaneous valves. A catheter-delivered device locates cavities occurring between a prosthetic valve (250) and the wall of the body vessel where the valve is implanted, the cavities producing paravalvular leaks during diastole, the device comprising at least one of a plurality of flexible wires, the wire having attached to it a balloon, wherein the balloon is pulled by the leak through the cavity and wherein the wire then serves to mark the cavity location.
