Electromagnetic heating temperature control system for in vivo memory alloy

Abstract

The invention discloses an electromagnetic heating temperature control system for in vivo memory alloy. The system includes a temperature sensing module used for sensing temperature change of the in vivo memory alloy, an in vitro electromagnetic heating module used for electromagnetic heating of the in vivo memory alloy, a temperature control module controlling whether the in vitro electromagneticheating module to work or not according a comparison result of the temperature sensed by the temperature sensing module and a threshold temperature, wherein a sensing terminal of the temperature sensing module is arranged in contact with the memory alloy, so that the accurate temperature of the in vivo memory alloy can be collected accurately. The temperature sensing module converts temperature signals to digital signals and sends to the temperature control module. The temperature control module performs analysis and comparison on the real time temperature and a preset target temperature, sothat the temperature control module can perform accurate control on the in vitro electromagnetic heating module according to the comparison result. Therefore, accurate control over the deformation range of the memory alloy can be realized and the accuracy of corrective procedures can be ensured.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an electromagnetic heating temperature control system for memory alloys in the body. Background technique [0002] Scoliotic deformity seriously affects the appearance, organ function, social ability, and psychological state of patients, especially adolescent idiopathic scoliosis patients. Therefore, if early intervention treatment is not available, it will seriously affect the normal development and growth of children . In the current prior art, although there is a device for correcting scoliosis designed with a memory alloy rod, it uses the principle of lateral translation correction to effectively correct the apical cone with the largest longitudinal load, thereby correcting the convexity of the vertebral body. Compressive stress is applied to the plate, and then tensile stress is applied to the end plate of the concave side of the vertebral body to restore the shape of the ver...

In the current prior art, although there is a device for correcting scoliosis designed with a memory alloy rod, it uses the principle of lateral translation correction to effectively correct the apical cone with the largest longitudinal load, thereby correcting the convexity of the vertebral body. Compressive stress is applied to the plate, and then tensile stress is applied to the end plate of the concave side of the vertebral body to restore the shape of the vertebral body and retain the growth ability of the spine. The fused frame reduces the occurrence of decoupling, short rods, etc. At the same time, although the patent application publication number CN 1697630A discloses the use of nickel-titanium memory alloy to correct spinal deformation, remote access tools including electromagnetic radiation components can be used for remote activation and correction Force or locking orthopedic operations, but because the temperature cannot be monitored in real time, it is impossible to guarantee the precise control of the deformation of the memory alloy and ensure safety
