Internal fracture fixing device

Abstract

The invention discloses a fracture internal fixing device. The fracture internal fixing device comprises: a steel plate and fixing nails, wherein the steel plate is fixedly connected with a bone through the fixing nails; a plurality of stress sensors, which are fixedly arranged on the outer surface of the steel plate and annularly distributed around the fixing nails; a built-in acquisition module,which is electrically connected with the plurality of the stress sensors; a built-in battery, which is arranged on the outer surface of the steel plate and is electrically connected with the stress sensors and the built-in acquisition module; and an external display, which is in wireless connection with the built-in acquisition module and is used for displaying data of the stress sensors. According to the invention, through arrangement of the stress sensors on the steel plate, the stress value of the steel plate can be detected and further visually displayed through the external display, so medical staff can conveniently judge whether the steel plate is broken or not in advance according to the change of the stress value to take preventive measures in advance; meanwhile, the steel plate taking-out opportunity can be roughly judged, and the treatment effect and efficiency are improved.

Description

Technical field [0001] The invention relates to the technical field of medical devices, and more specifically to a fracture internal fixation device. Background technique [0002] The vast majority of fracture patients require surgical treatment. Open reduction and internal fixation with steel plate fix the steel plate to the bone through steel nails to help fracture healing. Before the fracture is healed, the steel plate plays a role of stress support. After the fracture is healed, the steel plate often loses its stress support function. Therefore, the steel plate needs to be taken out of the patient; and in clinical practice, patients with broken steel plates are often encountered. Eventually lead to the failure of the operation and seriously affect the quality of life of the patient. However, the current method of judging whether there is a risk of fracture of the steel plate and the timing of when to remove the steel plate is generally based on postoperative imaging examinat...

Problems solved by technology

Before the fracture heals, the steel plate plays the role of stress support. After the fracture heals, the steel plate often loses the stress support function, so the steel plate needs to be taken out of the patient; and in clinical practice, patients with broken steel plates are often encountered. Ultimately lead to the failure of the operation, which seriously affects the quality of life of the patient

However, the current method of judging whether there is a risk of fracture of the steel plate and when to take out the steel plate generally relies on postoperative imaging examination (filming), which is time-consuming and laborious, and the treatment efficiency is low. Second, it relies on the experience of the operator and is less accurate.
