Magnetic control device for carrying wireless micro-devices to enter and exit abdominal cavity

Abstract

The invention belongs to the technical field of medical instruments, and provides a magnetic control device for carrying wireless micro-devices to enter and exit an abdominal cavity, wherein the magnetic control device is used for an intra-abdominal surgery and detection. The magnetic control device comprises an internal portion, an external portion and a feeder, the internal portion and the external portion are provided with corresponding magnetic materials, and a carrying bin is arranged in the front of the internal portion and can carry the micro-devices such as a wireless light source anda wireless camera. Magnetic materials are arranged at the front end of a telescopic rod of the feeder, the internal portion is fed into the abdominal cavity and magnetically draws with the external portion outside a body, the internal portion and the external portion are fixed inside and outside a front abdominal wall, and the internal portion is withdrawn and taken out after the surgery. Feeding,removal and fixation of the wireless micro-devices entering and exiting the abdominal cavity are finished by magnetic force, moving adjustment of the wireless micro-devices on the front abdominal wall is finished, the magnetic control device is simple and reasonable in design, reliable and practical, abdominal incisions are not increased, a plurality of light sources and a plurality of cameras can be arranged in the front abdominal wall in a dome-like combined manner, and effective assistance is provided for intra-abdominal shadowless lighting, stereoscopic camera shooting, wireless abdominalendoscopic surgeries and the like.

Description

technical field [0001] The invention relates to a magnetic control device equipped with wireless micro-equipment to enter and exit the abdominal cavity, which is used for laparoscopic surgery and relates to the technical field of medical instruments. Background technique [0002] Laparoscopic surgery supported by modern technology such as cold light source, camera and image display system has won the reputation of minimally invasive surgery for its small incision and quick recovery, and is widely used clinically. However, as a wired hard mirror that integrates camera and cold light source, its features and disadvantages are also very prominent: first, single-light illumination, which is blocked by instruments and affects surgical operations, which is a step backward compared to traditional surgical shadowless lighting; second It is a single lens, and the derived two-dimensional plane vision loses the three-dimensional sense of natural vision, and the visual reality of surgic...

However, as a wired hard mirror that integrates camera and cold light source, its features and disadvantages are also very prominent: first, single-light illumination, which is blocked by instruments and affects surgical operations, which is a step backward compared to traditional surgical shadowless lighting; second It is a single lens, and the derived two-dimensional plane vision loses the three-dimensional sense of natural vision, and the visual reality of surgical operations is reduced, requiring a considerable amount of time for adaptive training; moreover, the lighting and camera optical fibers are combined in a hard mirror to interact with each other. Overcrowded, both the operative field should be bright enough and the camera should be clear, which needs to be taken into account, and it is difficult to make it smaller and more minimally invasive; in addition, rigid mirrors, power cords, optical fibers and manipulation assistants (scope hands) occupy a considerable amount inside and outside the abdominal cavity. The operating space has certain obstacles to the operation of the surgeon, especially in the case of transumbilical single-port laparoscopic surgery, the rigid mirror and the operating instruments occupy each other in the limited navel, and the "chopstick effect" such as blocking the field of view and instrument collision during the operation Very prominent, in the development of umbilicus endoscopy that completely hides the surgical incision in the navel, it has shown its "flaws"
