Intelligent planning method and device for hand bone fracture nail placement channel

Abstract

The invention relates to an intelligent planning method and device for a hand bone fracture nail placement channel. The method comprises the following steps: acquiring a target image of a fractured hand bone; receiving a fractured skeleton area specified by a user in the target image; carrying out expansion and corrosion treatment on the fractured skeleton area so as to separate the fractured skeleton area into two island-shaped areas; according to the two island-shaped areas, determining a to-be-fixed nail placement channel through a preset channel determination strategy; and determining a target nail placement channel from the to-be-fixed nail placement channels. Thus, by obtaining the target image of the fractured hand bone, determining the to-be-fixed nail placement channel through the preset channel strategy and determining the target nail placement channel from the to-be-fixed nail placement channel, the nail placement channel can be accurately determined on the premise of taking the image data as the basis, intelligent planning of the nail placement channel is achieved, the reliability of planning of the nail placement channel can be improved, the risk coefficient of manually determining the nail placement channel is reduced, and excessive dependence on experience of doctors can be avoided.

Description

technical field [0001] The present disclosure relates to medical technology, and in particular, to an intelligent planning method and device for nail channels for treatment of hand bone fractures. Background technique [0002] Fixing the fracture fragments with steel nails after fracture is a commonly used treatment method in modern medicine. Fixing the fracture fragments with steel nails can avoid the displacement of the fracture fragments due to the pulling of other muscle tissues or ligaments, and ensure that the fractured bones are in the correct position. Position, heal with proper posture. However, if the position of the nail placement channel is determined incorrectly, the fractured bone cannot be completely fixed, or the position is inaccurate, it will have a certain impact on the fracture patient, such as the fractured bone heals at an inappropriate position, resulting in inconvenience for the patient after healing. Tolerate longer or more severe pain, loss of cons...

AI Technical Summary

Problems solved by technology

However, if the position of the nail placement channel is determined incorrectly, the fractured bone cannot be completely fixed, or the position is inaccurate, it will have a certain impact on the fracture patient, such as the fractured bone heals at an inappropriate position, resulting in inconvenience for the patient after healing. Tolerating longer or more severe pain, loss of consciousness in some areas of nerve damage, blood vessel damage, etc.

However, at present, doctors usually plan the position of the nail placement channel based on clinical experience, and artificially designate the nail placement channel according to the specific bone fracture condition. The risk factor is relatively low, and the risk factor will be higher for the position of the nailing channel determined by doctors who are not particularly rich in clinical experience
