Abstract

The invention belongs to the field of medical technology and discloses a control system capable of automatically controlling torque in taking out of a minimally invasive hollow nail. The control system comprises an X-ray shooting module, a parameter setting module, a center control module, a three-dimensional imaging device, an anesthesia module, an optical positioning module, a removing module and a displaying module. According to the invention, through the three-dimensional imaging module, an X-ray shooting image before an operation of a patient is read and a three-dimensional stereo image is generated, so the position of the hollow nail can be directly observed; meanwhile, through the optical positioning module, an optical tracking mark on a minimally invasive surgery device is capturedso that the space position of the hollow nail in the body of the patient is figured out in a quite precise manner, so the removing accuracy of the hollow nail is improved; and all the modules work under control of the center control module.

Description

technical field [0001] The invention belongs to the field of medical technology, and in particular relates to a control system for taking out a minimally invasive hollow nail with automatic torque control. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Minimally invasive is a technology that only causes minor trauma to the patient during the surgical treatment and leaves only minor wounds after surgery. It is a scientific and technological achievement compared to traditional surgery. Therefore, minimally invasive is a word specially connected with surgery and surgery, such as minimally invasive surgery, minimally invasive surgery, etc. However, in the existing minimally invasive hollow nail removal process, the position of the hollow nail is observed through a plane image, which is not intuitive; at the same time, the position of the hollow nail is drawn with a brush, and the positioning is not acc...
