At present, in the jaw bone repair and reconstruction operation, aiming at a large-area jaw bone defect patient, vascularized osseous muscle flap free transplantation is generally used, and the commonly used osseous muscle flaps are fibula flaps and ilium flaps. Because the jaw bone is of an irregular structure, the transplanted bone flap is required to be shaped in a three-dimensional form in the operation process so as to meet the repair requirement. After the skeletal muscle flap is cut, the cutting and shaping are completed as soon as possible to make the skeletal muscle flap conform to the jaw bone shape of the affected area, and then the vascular anastomosis and fixation are performed. However, at present, when a surgeon performs bone graft shaping, the surgeon still mostly uses handheld forceps to fix, the operation has high requirements on the strength and skill of a main surgeon and an assistant, and because the forceps are required to be clamped again to fix bone blocks every time, and complex shaping is completed, and multiple times of cutting and adjustment are required, the method for fixing the bone graft to perform the shaping work usually occupies a large amount of operation time and energy of the surgeon, and is not easy to perform delicate operation. In addition, the duration of the free musculoskeletal flap ischemia can influence the survival rate of the musculoskeletal flap, and the molding effect of the musculoskeletal flap can also influence the function and the beauty of the jaw bone of the patient after the operation. Therefore, at present, the fine shaping of the musculoskeletal flap is one of the key points and difficulties of the free transplantation of the vascularized musculoskeletal flap, and how to efficiently and accurately shape the musculoskeletal flap is a problem that surgeons want to solve.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Fig. 1 shows an embodiment of the present invention, which includes a bottom plate 2 and two fixing components, each of which includes an absorption component, a fixed jaw 7, a movable jaw 8 and a clamping component; the adsorption component is positioned at the lower end of the fixed jaw 7, is fixedly connected with the fixed jaw 7 and is fixed on the bottom plate 2 in a magnet adsorption mode, the adsorption component comprises a shell 4, a knob 5 and a magnet 6, the magnet 6 is arranged in the shell 4, and the knob 5 is arranged on the shell 4 and is fixedly connected with the magnet 6 in the shell 4; the movable jaw 8 is opened and closed through rotation relative to the fixed jaw 7; the clamping assembly comprises a connecting rod 9, a ratchet 13, a bolt fixing block 10, a groove 15, a long hole 16, a bolt 11, a spring 12 and a nut 14, the upper end of the connecting rod 9 is hinged to a handle of the movable jaw 8, the lower end of the connecting rod is hinged to the bolt fixing block 10, the middle of the fixed jaw 7 is provided with the groove 15 and the long hole 16 which penetrates through the groove 15, the ratchet 13 is installed in the groove 15, the bolt fixing block 10 is installed in the long hole 16 and can slide up and down along the long hole 16, and the bolt 11, the spring 12 and the nut 14 are arranged in an inner cavity of the bolt fixing block 10; the clamping assembly may prevent the movable jaw 8 from moving to maintain the clamped state.
In the above embodiment, two identical fixing parts are used for fixing a large block/long bone, and the two fixing parts are adsorbed on an iron bottom plate 2 together; the knob 5 of the adsorption component is fixedly connected with the magnet 6, and the magnet 6 is driven to rotate by rotating the knob 5, so that the polarity of the magnet 6 is changed, and the fixed part and the bottom plate 2 are adsorbed, fixed or detached; in order to prevent the iron bottom plate 2 from rusting and being difficult to clean, the bottom plate 2 is preferably subjected to electroplating treatment; when the two fixing parts work cooperatively, when the position or the direction of any one fixing part needs to be adjusted, the operation can be flexibly carried out only by rotating the knob 5, thereby greatly saving the time for shaping the transplanted bone and improving the working efficiency. Of course, if the bone to be shaped is small, a fixing member may be used for fixing.
