Shaping and reinforcing device for transplanted bone

Abstract

The invention discloses a shaping and reinforcing device for a transplanted bone. The device comprises a chassis, a shaping arm, a force arm, a gland and a shaft type joint, shaping arms are arrangedat the top end of the chassis at equal intervals; every two adjacent shaping arms are hinged through a shaft type joint; a force arm is hinged to the outer wall of one side of the shaft type joint. Alengthened handle rod is arranged at one end of the force arm; the surface of the shaft type joint is sleeved with a fixing ring. Rotary accommodating grooves are formed in the surfaces of the shapingarm and the force arm on the outer side of the fixing ring; the fixing ring is located in the rotary containing groove. Meanwhile, the depth of the rotary containing groove is larger than the thickness of the fixing ring, a gland is arranged on the inner side of the shaping arm, a handle is installed in the center of the surface of the gland, and horizontal columns are embedded in the two outer side walls of the bottom of the substrate. According to the invention, the convenience of extrusion reinforcement of the shaping reinforcer is improved, the simulation and fixation functions of any defected bone shape are realized, and the stress uniformity of the gland during pressing is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a bone grafting plastic reinforcement. Background technique [0002] In clinical orthopedic surgery, bone grafting is often required for patients with fracture defects. Bone grafting is divided into autologous bone and artificial bone, and the main method of transplantation is direct packing. However, in actual operation, there is often a problem of matching the shape of the grafted bone with the defect site. At present, 3D printing technology still has problems such as low popularity and poor economy. Manual kneading has poor accuracy and is not easy to shape firmly. Therefore, plastic reinforcement is usually used for bone grafting in clinical practice. [0003] Chinese Patent No. 2018209291570.6 discloses an alveolar bone shaper, which includes a bone support, which includes a contact surface that cooperates with the alveolar bone and an inner cavity for dental implan...
