Abstract

The invention discloses a knee joint posterior cruciate ligament tibial insertion avulsion fracture bone fracture plate 3D printing device, and relates to the technical field of 3D printing. Comprising a base and a placing plate, a shell and a first supporting block are connected to the base, a first supporting plate is connected to the first supporting block, a moving assembly is arranged between the first supporting plate and a first gear ring, a first supporting frame is arranged on the moving assembly, a plurality of first motors are hinged to the first supporting frame, and first sleeves are connected to the first motors through connecting plates; a second sleeve is connected to an output shaft of the first motor, sliding rods are inserted into the second sleeve, sliding grooves are formed in the circumferential sides of the sliding rods, guide blocks are connected to the inner side wall of the second sleeve, the multiple sliding rods are hinged through a first connecting frame, and a spraying assembly is arranged on the first connecting frame. Lateral printing can be achieved, and the application range of the device is widened.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a 3D printing device for a bone plate for avulsion fracture of the posterior cruciate ligament of the knee joint. Background technique [0002] The bone plate used for the avulsion fracture of the posterior cruciate ligament of the knee joint often needs to be customized according to the specific situation of the patient, and the shape of the bone plate is different, sometimes some parts are inclined in one direction, and 3D printing needs to be adjusted. This part of the support can be printed, but the support will affect the structure due to the hot melt state [0003] The existing 3D printing has vertical and inclined, but there is no 3D printer that can adjust the vertical and inclined printing at any time, and in the face of parts with different shapes, it is necessary to select the printing angle and direction in advance. A lot of time, can not print in tim...
