Description

Wireless laparoscope

Technical Field

The invention discloses a wireless abdominal cavity endoscope system and a using method thereof, which are used for abdominal cavity examination and operation and relate to the technical field of medical instruments.

Background

The shadowless lamp and the naked eye direct vision are the characteristics of the traditional abdominal open surgery, the straightness characteristics of light rays and sight restrict the freedom degree of the surgery, and the mutual crowding effect exists between the shadowless lamp and the head of an operator and between the operator and an assistant, so that a large incision is often needed for compensation.

The laparoscopic surgery consisting of the pneumoperitoneum machine, the cold light source optical fiber, the camera imaging system and the digital television obviously changes the defects, and the illumination is transmitted into the abdomen through the optical fiber cable; the intra-abdominal images obtained by video camera connection are displayed on a television screen, the crowding effect of the light and the sight is changed in a cable mode, the operation incision is changed from meeting the requirements of the light, the sight and the operation to the requirement of only supplying the equipment and the instruments through the abdominal wall, namely a plurality of key holes, and the abdominal operation is in a minimally invasive age. From multi-aperture to single-aperture, multi-site incisions to transumbilical single-site incisions, the continuing evolution of laparoscopic surgery is moving forward to the aesthetic healing boundary of no visible knife marks after surgery. At the same time, the defects of laparoscopy are also objectively revealed:

1. the armrest and associated physical obstructions: the special role derived from the prior laparoscope technology, namely, the assistant special for the laparoscope on the operating table holds the angle and the distance of the laparoscope to provide illumination and an operation visual field for the whole operation, the posture of the hand of the laparoscope is often different from the intention of a doctor at the main knife, the training and running-in of considerable time and examples are needed for realizing the tacit cooperation, and the extra labor cost is increased and difficult to be introduced. The laparoscope body and the cable thereof have physical obstacles such as occupation, touch, limitation and the like on surgical instruments and surgical operations, and particularly hinder ultra-minimally invasive development of the transumbilical single-site laparoscope.

2. Two-dimensional plane operation field: the laparoscope is limited to monocular photography and imaging technology, the view field of the laparoscope is a two-dimensional plane, deep vision is lacked, long-time special training is needed to adapt, and the laparoscope is a step back compared with the natural three-dimensional view field of open surgery;

3. shadow illumination: the illumination of the laparoscope is monocular illumination, and the problem that the operating instrument blocks light exists, so that the operating freedom of an operator is influenced. Compared with the shadowless lamp for open operation, the shadowless lamp is changed from shadowless illumination to shadowy illumination, which is a step back;

4. contradiction between brightness and resolution: the illumination optical fiber and the video cable are bound in the same lens body, and the thickness (and performance) of the illumination optical fiber and the video cable are reduced, so that the brightness and the resolution are improved, and the expectation of reducing the lens body is limited. The lighting angle and the camera shooting angle are coaxial and coplanar, the natural ecological included angle between light rays and sight lines is lost, and the phenomenon of convex light reflection distortion exists particularly when the front surface of the 0-degree mirror is irradiated.

These defects are inherent defects of laparoscopy, and are mainly caused by wired mode of laparoscopy and monocular and rigid characteristics of light and mirror.

The progress of bluetooth, WIFI, 4G, 5G's image wireless transmission and display screens such as 4K, 8K provides the scientific and technological guarantee for solving these defects. The present invention introduces these modern wireless communication technologies into the evolution of laparoscopy, provides a systematic wireless laparoscopic solution, eliminates the role of a scope holder and greatly improves the above-mentioned drawbacks.
