Embodiment 1

[0042] A kind of orthopedic surgery simulation method 100, such as figure 1 shown, including:

[0043] Step 110, receiving the cutting point information and pre-clearing site information input by the user, and marking the cutting position point corresponding to the cutting point information on the bone model;

[0044] Step 120: Aiming at the shortest connection line, connect two adjacent cutting position points along the edge of the smallest geometric unit constituting the bone model to form a closed zigzag cutting boundary;

[0045] Step 130, moving the points corresponding to the cutting position points on the closed jagged cutting boundary to shorten the distance between adjacent points to form a closed and smooth cutting boundary;

[0046] Step 140, starting from the closed smooth cutting boundary, traversing and clearing all the edges of the smallest geometric units corresponding to the pre-cleared part information to realize bone cutting, and forming a cutting plane based...

Embodiment 2

[0080] A storage medium stores instructions in the storage medium, and when the computer reads the instructions, the computer is made to execute any bone surgery simulation method described in the first embodiment above.

[0081] It should be noted that any orthopedic surgery simulation method in Embodiment 1 can also constitute a kind of orthopedic surgery simulation system, which includes:

[0082] The cutting position point marking module is used to receive the cutting point information and pre-cleared part information input by the user, and mark the cutting position point corresponding to the cutting point information on the bone model;

[0083] The closed zigzag cutting boundary forming module is used to connect two adjacent cutting position points along the edge of the smallest geometric unit constituting the bone model to form a closed zigzag cutting boundary with the goal of the shortest connection line;

[0084] The closed smooth cutting boundary forming module is use...

Embodiment 3

[0092] A preoperative demonstration system for orthopedic surgery includes: an intelligent terminal and a storage medium as described in the second embodiment above. The smart terminal is used to receive and display the bone model input by the user, and when receiving the cutting point information and pre-clearing site information input by the user, read the instructions in the storage medium, and clear the pre-clearing on the bone model based on the cutting point information The part corresponding to the part information and form a cutting surface, or remove the part corresponding to the pre-cleared part information on the bone model and form a cutting surface and form a metal block with the same shape as the removed part.

[0093] Such as figure 2 In the humanized pelvis model shown, the cutting point and the position of the cutting point farthest from the above cutting point are as follows: image 3 As shown, the dotted circle represents the cutting position, and the lowe...

Abstract

The invention discloses an orthopedic surgery simulation method and an application thereof, and the method comprises the steps: receiving cutting point information and pre-clearing part information inputted by a user, and marking a cutting position point corresponding to the cutting point information on a bone model; taking the shortest connecting line as a target, and connecting every two adjacent cutting position points along the edge forming the minimum geometric unit of the bone model to form a closed sawtooth-shaped cutting boundary; smoothing each included angle on the closed sawtooth-shaped cutting boundary into an obtuse angle to form a closed smooth cutting boundary; from the closed smooth cutting boundary, traversing the edges of all the minimum geometric units corresponding to the pre-removed part information and removing the edges to realize bone cutting, and forming a cutting surface based on the closed smooth cutting boundary. A bone cutting simulation algorithm providedby the invention provides a visual way for clearly describing the operation process for a patient and family members thereof before an operation, and also provides a new way for teachers to perform operation teaching on new doctors, so the operation teaching and practice cost can be reduced, and the user experience can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of operation simulation algorithms, and more particularly relates to a simulation method for orthopedic surgery and its application. Background technique [0002] The pace of people's life and work is getting faster and faster, and the pressure is also increasing. As a result, people's health is threatened to a certain extent, and there are more and more operations. Patients and their families have always been concerned about the operation process. Therefore, how to explain clearly to them before operation is an important task for doctors. In addition, for the cultivation of high-quality doctors, it is also very important for the professor to explain the operation process to the students, and in order to improve the teaching effect, the demonstration of the operation process plays a decisive role. [0003] Based on the above practical needs, image processing for orthopedic surgery began to be applied to Mic...
