Auxiliary device for minimally invasive surgery and control method thereof

Abstract

The present invention provides a minimally invasive surgery assisting device, comprising: an extracorporeal device, the extracorporeal device including an external magnetic generating device providing a rotating magnetic field, a driving mechanism for driving the external magnetic generating device to move and / or rotate; an internal device, The internal device includes a magnetic auxiliary part and a fixing clip connected with the magnetic auxiliary part; a positioning probe, the positioning probe includes a magnetic field sensor for detecting the magnetic field strength of the external magnetic generation device; a control system, the driving mechanism, The positioning probes are directly or indirectly connected to the control system; the present invention can achieve the effects of easy control of the rolling angle of the mucosa, high operation repeatability, fast speed, and safety and reliability for the mucosa to be peeled off in any spatial orientation. .

Description

technical field [0001] The invention relates to an auxiliary device for minimally invasive surgery, in particular to an auxiliary device for minimally invasive surgery that can assist in expanding the surgical field and a control method thereof. Background technique [0002] Minimally invasive surgery, as a treatment method to change the traditional surgical mode, has won the favor of hospitals and doctors for its advantages of less bleeding, small wounds, less impact on organ functions, quick recovery, and fewer postoperative complications. Substantial breakthroughs and applications have been achieved in many surgical operations. While the advantages of minimally invasive surgery are being recognized more and more, its defects are also gradually revealed, such as extended learning time for doctors and higher requirements for operational accuracy; traditional surgical instruments can no longer meet the needs, and need to be continuously improved or even completely Innovatio...

Problems solved by technology

However, the specific spatial position and orientation information of the mucosa cannot be obtained only through endoscopic image feedback, making it difficult for an external magnet to precisely control the rolling of the mucosa in the desired direction, and only rely on the operator to observe the movement direction of the magnetic column in the body relative to the mucosa Continuous trial and error, controlling the direction of the magnetic field outside the body to roll over the mucosa, such an operation method is difficult, with low operation repeatability, long time, and low safety, which is not conducive to the promotion and application of magnetically controlled stretching technology in ESD clinical practice
