Calcaneal-fracture-closed-reduction-internal-fixation assisting method based on digitized 3D printing tool

Abstract

The invention discloses a calcaneal-fracture-closed-reduction-internal-fixation assisting method based on a digitized 3D printing tool. The method includes the steps of modeling and analyzing an illness state; simulating fracture reduction; determining the position of an internal fixation device; determining positions of reduction kirschner wires after fracture reduction; determining positions ofthe reduction kirschner wires before fracture reduction; designing a steering tool before fracture reduction; designing a fracture internal fixator implantation guide plate; preparing and testing allsteering tools through 3D printing.

Description

technical field [0001] The invention relates to the field of 3D printing and fracture reduction and fixation, in particular to an auxiliary method for closed reduction and internal fixation of calcaneal fractures based on digital 3D printing tools. Background technique [0002] Closed reduction and internal fixation of fractures: refers to a surgical method of closed reduction and internal fixation of fractures. It is a combined process of closed reduction and internal fixation of fractures. [0003] Closed reduction of a fracture: A surgical procedure that restores the correct anatomical relationship between the fracture pieces without incising or exposing the fractured area. [0004] Internal fixation of fractures: A surgical method that connects the fracture fragments into a whole through internal fixation devices such as screws, steel plates, intramedullary nails, and steel wires, and helps the fractures to maintain a relatively fixed position and heal.

AI Technical Summary

Problems solved by technology

[0014] 1. Before the operation, the details of the calcaneal fracture cannot be intuitively understood;

[0015] 2. Before the operation, it is impossible to intuitively and repeatedly carry out surgical planning and simulated surgery, so as to determine the operation plan of calcaneal fracture closed reduction and internal fixation;

[0016] 3. Before the operation, the type and model of the internal fixation device cannot be completely determined;

[0017] 4. During the operation, a small incision is still required to expose the subtalar articular surface;

[0018] 5. During the operation, the fracture of the calcaneus must be confirmed through real-time observation (such as: subtalar joint micro-incision, repeated intraoperative X-ray fluoroscopy, etc.);

[0019] 6. During the operation, repeated attempts are required to obtain a satisfactory reset;

[0020] 7. During the operation, the installation position of the internal fixation device is not accurate;

[0022] 9. During the operation, the internal fixation device must be installed after repeated intraoperative X-ray fluoroscopy guidance or verification
