Abstract

The invention discloses a guide pin positioning guide plate customization and simulation verification system and a method thereof. The guide pin positioning guide plate customization and simulation verification system comprises a data receiving input module, a data processing module, a three-dimensional reconstruction module, a guide plate model matching module, a guide plate model verification module, a data output module, a guide plate manufacturing system, and an interactive query module. The interactive query module is respectively connected with the three-dimensional reconstruction module, the guide plate model matching module and the guide plate model verification module; the guide plate model verification module comprises a guide pin insertion verification module and a simulation verification module. According to the guide pin positioning guide plate customization and simulation verification system and the method thereof, CT data is processed, a skeleton three-dimensional model is reconstructed, then a guide plate model is obtained through fitting and matching in the skeleton three-dimensional model according to skeleton three-dimensional data, various verifications such as guide pin insertion operation simulation verification and simulation activity verification can be achieved, operation simulation, error correction, drilling and verification can be carried out in the guide pin positioning guide plate customization and simulation verification system. Meanwhile, a customized and personalized guide plate can be accurately printed and manufactured, and operation implementation is facilitated.

Description

technical field [0001] The invention relates to a fracture medical system, in particular to a guide pin positioning guide plate customization and simulation verification system and method thereof. Background technique [0002] Fracture is a relatively common injury in the elderly. Due to the decline in bone density and osteoporosis in the elderly, the chance of fracture after a fall is greater. Most patients with fractures require surgery, and one of the most common surgical methods is the placement of internal fixators in the bone for fixation. In the operation, the internal fixation is inserted into the frame (mainly bone) and the fracture site is connected with the whole frame. The position and angle of the internal fixation are determined by the initially inserted guide wire. Therefore, when inserting the guide wire, the requirements for the insertion angle and insertion point of the guide wire are very high. When inserting the guide pin, the guide pin will easily devi...

Problems solved by technology

When inserting the guide pin, the guide pin will easily deviate from the designed path, or even deviate from the optimal surgical point. If the guide pin is not inserted according to the optimal design path, it will easily lead to poor fixation effect, and the patient will need a long period of postoperative recuperation. The risk of a second operation, and even the possibility of internal fixation loosening and fracture displacement

Traditional fracture surgery operations often require experienced attending doctors to perform surgical treatment. Generally speaking, the main steps of fracture surgery are anesthesia, incision, guide pin insertion, reaming, main nail insertion, guide pin extraction, and screw insertion. The blade and the distal end are locked and stapled and sutured; during the operation of fracture surgery, especially the process of inserting the guide pin, fluoroscopy confirmation is required at any time (the difficulty of the operation is mainly the insertion angle and insertion point of the guide pin, and fluoroscopy is also for observing the guide pin at any time). Whether there is deviation of the needle), resulting in long operation time and high radiation, especially for the elderly, the long operation process is likely to bring more negative effects, complications, and even death

Therefore, the step of inserting the guide pin in fracture surgery requires high requirements on the position and angle of the guide pin. The clinical experience of the attending doctor will have a great impact on the time and effect of the operation. There is no instrument and simulation study to assist guide pin insertion, the tools used are simple, the guide pin cannot be positioned accurately, and it all depends on the doctor's surgical experience
