Description
Technical Field
The invention relates to the field of medical instruments, in particular to a minimally invasive surgery magnetic anchoring system, a control module and a minimally invasive surgery auxiliary device.
Background
With the rapid development of the minimally invasive endoscope technology in the medical field, more and more early gastric cancer, intestinal cancer, precancerous lesion and gastrointestinal submucosal diseases can be removed under the endoscope through a minimally invasive operation, so that larger operation wounds are avoided. Such as Endoscopic Submucosal Dissection (ESD), ESD surgery allows for the total removal of lesions with diameters greater than 2cm, compared to conventional Endoscopic surgery, thereby avoiding local recurrence. However, ESD has the defects of long operation time, high risk, difficult operation and the like, especially when lesions with a diameter of more than 3cm are completely peeled off, complications such as bleeding and perforation are easy to occur, and the most important point for avoiding perforation of the digestive tract in the operation is to keep the operation visual field clear all the time in the ESD operation. Generally, the ESD operation is to operate the thin-wall hollow viscera in a limited space, the angle can be adjusted only in a limited way through an endoscope, effective operative field exposure is lacked, the operation difficulty is high, and the technical requirement is high.
To solve the above problems, Magnetic anchoring-assisted endoscopic mucosal dissection (MAG-ESD) has been developed internationally. This technical scheme utilizes the scope passageway will take the magnetic ring anchor clamp to fix in intracavity pathological change tissue edge, and external magnet fully pulls with different angles to the operation district and shows, effectively assists scope doctor's operation, reduces the operation degree of difficulty and perforation risk.
