AI Technical Summary

Technical Problem

Existing axillary fixation systems cannot dynamically optimize the initial positioning and real-time adjustment of the axillary blocking post based on the patient's individual body shape parameters, resulting in uneven pressure, traction failure, and local tissue compression damage, which affects surgical safety and repositioning effectiveness.

Method used

The acquisition module accurately collects physiological data such as shoulder width and axillary depth of patients, and calculates initial positioning parameters by combining BMI body type classification. The primary adjustment module adjusts the angle and position of the blocking column in real time, the secondary adjustment module monitors the traction status, and the early warning module monitors the equipment status in multiple dimensions, so as to achieve personalized positioning of the blocking column and stability of the traction process.

Benefits of technology

It achieves personalized initial positioning of the blocking column, avoids errors caused by manual setting, ensures balanced local pressure, improves fixation safety, guarantees fracture reduction accuracy, and reduces surgical risks.

Abstract

The present application relates to the technical field of orthopedic surgical equipment, in particular to an axillary counter-traction humeral fracture intraoperative body position fixing system and method, comprising: a collection module, a primary adjustment module, a secondary adjustment module and a warning module; the collection module collects physiological data such as patient shoulder width and axillary depth, and calculates the initial positioning parameters of the blocking column in combination with BMI body type classification; the primary adjustment module synchronously collects pressure and temperature data, and adjusts the angle and position of the blocking column in real time to ensure pressure balance; the secondary adjustment module monitors the traction state, and maintains traction stability through pressure-angle double compensation; the warning module multi-dimensionally monitors the equipment operation and protection state, and accurately identifies abnormal scenarios. The present application realizes personalized adaptation and intelligent regulation and control of body position fixation, improves surgical reduction accuracy and safety, and effectively reduces the risk of local tissue damage and traction failure.
