The multifunctional cervical vertebra repairing pillow comprises a pillow body, a back sleeping area, side sleeping areas, a neck support and a hardness adjusting structure, the pillow body is of a rectangular structure, the back sleeping area is arranged in the middle of the top of the pillow body, the back sleeping area is in a concave shape, the side sleeping areas are arranged on the two sides of the back sleeping area, and the neck support is fixedly connected to the front side of the pillow body. The neck support is cylindrical, a magnet area is arranged in the middle of the top of the neck support, and the hardness adjusting structure is arranged in the side sleeping area and the neck support. Compared with the prior art, the pillow has the advantages that the neck support is cylindrical, higher than the surface of the pillow body and used for supporting the cervical vertebra and keeping the cervical vertebra in a comfortable posture, the magnet area is arranged in the middle of the top of the neck support, and the cervical vertebra condition is further improved through the magnetic therapy effect.

The utility model relates to ophthalmic operation technical field discloses a kind of posterior sclera pad pressure implant, including silica gel piece, multiple suture holes are opened in both ends of silica gel piece, storage cavity is opened in silica gel piece, the silica gel piece located at the both sides in storage cavity is also opened and placed inlet, pressure block is movably installed in storage cavity, gasket is movably installed between the bottom of pressure block and storage cavity, the inboard of storage cavity is also coated with ion exchange coating.Place inlet design can place pressure block and gasket before suturing, convenient operation, and pressure block adopts hydrogel, can flexibly adapt to eye demand and cooperate with the silica gel material quality and limit protrusion of gasket, effectively limit pressure block movement, and reduce the pressure of pressure block to eye socket inside, simultaneously, the ion exchange coating in storage cavity, can accurately position hydrogel, improve support accuracy, near macular area Special arc-shaped structure and thickening design, enhanced the pertinence support to macular area, can effectively improve patient eye condition, improve operation effect.

The application provides a reciprocating driving mechanism of a curved needle in a laparoscope suture device, which comprises a suture driving wheel, a curved needle transmission connecting rod and a guide connecting rod; the first end of the curved needle transmission connecting rod is hinged to one point of the curved needle, the second end of the curved needle transmission connecting rod is hinged to the suture driving wheel, the first end of the guide connecting rod is hinged to the curved needle transmission connecting rod, the second end of the guide connecting rod is hinged to a curved needle mounting block, the line from the hinge point of the curved needle transmission connecting rod and the suture driving wheel to the rotation center of the suture driving wheel is always parallel to the guide connecting rod, the line from the hinge point of the guide connecting rod and the curved needle mounting block to the rotation center of the suture driving wheel is always parallel to the curved needle transmission connecting rod, the curved needle is driven to move along the curved needle groove in the form of double parallelogram transmission, the translation of the curved needle transmission connecting rod is ensured, the driving force of the curved needle is always kept in the direction of tangent line, that is, the direction of maximum effective force, and the motion condition of the curved needle and the quality of surgical suturing are improved.
