DETAILED DESCRIPTION

[0024] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0025] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-4As shown, the embodiment of the utility model provides a needle for injection between soft tissue and hard tissue: comprising a needle tube 1, one side of the needle tube 1 is fixedly connected to a support rod 2, one end of the support rod 2 is rotatably connected to a turntable 3, one side of the turntable 3 is fixedly connected to a connecting rod 1 41 and a connecting rod 2 42, the outer walls of the connecting rod 1 41 and the connecting rod 2 42 are hinged with a connecting rod 3 5, a connecting rod 46 is arranged on the side of the turntable 3 away from the needle tube 1, one end of the connecting rod 46 is fixedly connected to a threaded rod 1 7, the other end of the connecting rod 46 is fixedly connected to a threaded rod 2 8, the outer wall of the threaded rod 2 8 is rotatably connected to a limiting block 21, the The limit block 21 is fixedly connected to the needle tube 1, and the outer walls of the threaded rod 2 8 and the threaded rod 1 7 are threadedly connected with a connecting block 9, and the connecting block 9 is hinged to one end of the connecting rod 3 5 away from the connecting rod 1 41 and the connecting rod 2 42, and the side of the turntable 3 close to the needle tube 1 is fixedly connected with a short rod 10, and the outer wall of the short rod 10 is hinged with a long rod 11, and the end of the long rod 11 away from the short rod 10 is hinged with a shell 12, and a needle 131 is slidably connected in the shell 12, and one end of the needle 131 is fixedly connected to a hose 132, and one end of the hose 132 is fixedly connected to a needle 2 133, and the needle 2 133 is connected to one end of the needle tube 1.

[0027] In one embodiment, an auxiliary plate 14 is fixedly connected to the outer wall of one end of the needle tube 1, a piston body 15 is slidably connected inside the needle tube 1, an end of the piston body 15 away from the needle tube 1 is fixedly connected to a piston handle 16, and an outer wall of one end of the piston body 15 located inside the needle tube 1 is fixedly connected to a piston gasket 19.

[0028] In one embodiment, a groove 17 is provided on the side of the piston handle 16 away from the needle tube 1, and an anti-skid particle 18 is fixedly connected in the groove 17. A handle 20 is fixedly connected to one end of the threaded rod 28 close to the piston handle 16. There are multiple anti-skid particles 18, and the multiple anti-skid particles 18 are evenly distributed. The multiple anti-skid particles 18 play an anti-skid role to prevent medical staff from slipping when pressing the piston handle 16. The threaded directions of the threaded rod 17 and the threaded rod 28 are opposite.

[0029] When the utility model is in operation: the medical staff holds the needle tube 1 and the piston handle 16, and sucks the medicine into the needle tube 1 through the cooperation of the piston body 15, the piston handle 16 and the piston gasket 19, and rotates the handle 20 according to the required angle. Since the handle 20 is fixedly connected with the connecting rod 4 6, the threaded rod 1 7 and the threaded rod 2 8, the rotation of the handle 20 drives the connecting rod 4 6, the threaded rod 1 7 and the threaded rod 2 8 to rotate. Since the connecting block 9 is threadedly connected with the threaded rod 1 7 and the threaded rod 2 8, the connecting block 9 moves on the outer wall of the threaded rod 1 7 and the threaded rod 2 8. Since the thread directions of the threaded rod 1 7 and the threaded rod 2 8 are opposite, the two connecting blocks 9 are close to each other. With the cooperation of the limit block 21, the connecting rod four 6, the threaded rod one 7 and the threaded rod two 8 rotate but do not move, and with the cooperation of the connecting rod three 5, the turntable 3 finally rotates counterclockwise around the support rod 2. Since the turntable 3 and the needle 131 are connected by the short rod 10, the long rod 11 and the shell 12, the needle 131 is driven to rotate during the rotation of the turntable 3, and the purpose of adjusting the angle of the needle 131 is finally achieved with the cooperation of the hose 132, and it can be adjusted at any time according to different needs, which is convenient for medical staff to use; after the adjustment is completed, the medical staff's thumb pushes the groove 17 according to the position of the groove 17 and the cooperation of the piston handle 16 to complete the injection to prevent slipping.

[0030] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
