The present disclosure relates to modular plate tips for prophylactic cervical fixation for use in the treatment of metaphyseal fractures.SOLUTION: The device includes a body 110 having a connecting portion 130 connectable to a bone plate and an anchoring portion 120 attachable to a bone. The connecting portion 130 has a top surface 121 configured to face away from the bone and a bottom surface 122 configured to face toward the bone. The bottom surface 122 of the connection portion 130 has a first shelf 134 extending substantially perpendicularly from the bottom surface 122 at a first side 132a of the bottom surface 122 and a second shelf 135 extending substantially perpendicularly from the bottom surface 122 at a second side 132b of the bottom surface 122. The second shelf 135 includes a rail 136 that extends toward the first shelf 134 such that the second shelf 135 defines an undercut between the rail 136 and the bottom surface 132.SELECTED DRAWING: Figure 1A-B

The invention relates to the technical field of medical instruments, in particular to a swallowing function training and neck fixing composite device after anterior cervical surgery, which comprises a fixing box, a liquid storage box is fixedly connected to the bottom of the fixing box, disinfectant is filled in the liquid storage box, and straps are symmetrically and fixedly connected to the outer side wall of the liquid storage box. Telescopic pieces are symmetrically and fixedly connected to the two inner side walls of the fixed box; a first neck fixing assembly is arranged on the fixing box, and transmission assemblies are arranged on output shafts of the telescopic pieces. A second neck fixing assembly, a swallowing training assembly and a disinfection assembly are further arranged in the fixing box. Multi-stage fixing of the neck of a patient is achieved through the first neck fixing assembly and the second neck fixing assembly, the second neck fixing assembly and the swallowing training assembly cooperate, the patient is assisted in swallowing training while the neck of the patient is fixed, the collaboration of the fixing function and the auxiliary swallowing function is improved, and the swallowing training effect of the patient is improved. The rehabilitation efficiency and the rehabilitation quality of the patient are improved.

The invention relates to the technical field of medical instruments, in particular to a rear pillow type cervical vertebra fixing device which is mounted on a base and comprises a cervical vertebra pillow, an up-down position adjusting mechanism and a front-back position adjusting mechanism. The axial middle part of the cervical vertebra pillow is provided with a concave circular arc curved surface which is attached to the rear part of the cervical vertebra of a human body, and each radial section in the axial position of the cervical vertebra pillow is a circular arc surface of which the curvature is gradually changed; the concave arc in the axial middle of the cervical pillow is in contact with the cervical vertebra of a human body to fix the position of the cervical vertebra and prevent the cervical vertebra from moving leftwards and rightwards; the middle concave arc allows the head to rotate backwards under the action of pushing force, the cervical pillow serves as a contact support of the rear portion of the cervical vertebra during cervical traction, and when the pushing mechanism acts, the lower jaw rotating bracket for supporting the head is pushed to rotate in the curved direction along the rotating center shaft arranged on the rear portion of the cervical vertebra, so that the head of the human body conducts curved arc traction backwards. Existing upward lifting type traction is converted into curved traction, so that the cervical vertebra can naturally stretch, and the original curvature of the cervical vertebra is recovered.
