Description

Technical Field

[0001] The present invention relates to the field of medical instruments, and in particular to a power line distribution device for surgical equipment. Background Art

[0002] A conventional minimally invasive surgical operation requires multiple medical devices such as an operating table, anesthesia machine, monitor, infusion pump, laparoscope system, microscope, high-frequency electrosurgical unit, power system, etc. During the specific operation, the surgeon, nurses, and personnel wearing sterile clothing and sterile gloves are usually required to stand next to the operating table. After that, other staff will move various equipment around the operating table area. Because each device must have a power cord, there are at least seven or eight or even more than a dozen wires around the operating table. The number of the above wires is large and the lengths are different. The wires are freely scattered on the floor of the operating room. Not only are they easily pulled or crushed by mistake, but they also affect the placement of medical equipment and restrict the free movement of staff.

[0003] In order to solve the above technical problems, the current conventional practice in hospitals is to directly take electricity from the wall socket. And cover various power cords with cloth to prevent the wires from being pulled and stepped on to a certain extent. However, the above-mentioned scheme of taking electricity from the wall socket will cause a large number of wires and long distances in the corridor for various medical equipment. The above-mentioned excessive and long wires are easily damaged by being stepped on and crushed by the wheels of medical equipment, and will also affect the placement of surgical equipment and the movement of staff. In addition, another conventional practice in hospitals is to guide a plug board to the bottom of the operating bed through wires, and various equipment takes electricity from the plug board under the operating bed. Although taking electricity from the plug board under the operating bed avoids the problem of too many wires in the corridor. However, since the power cords of the equipment are usually relatively long, this will cause the wires between the operating bed and various medical equipment to be many and long, and the above-mentioned wires are also easily damaged by being stepped on or crushed by wheels, and will also affect the position of the surgeon and nurse. Moreover, in the above-mentioned scheme of taking electricity from the wall socket and the above-mentioned scheme of taking electricity from the plug board at the bottom of the operating bed, there is a problem of wires being entangled with each other. The excessive and long wires mentioned above are entangled with each other and may be pulled accidentally, which may cause the surgical equipment to lose power and shut down, resulting in sudden interruption of the operation, affecting the medical effect and even causing medical safety risks.

[0004] Therefore, technical personnel in this field urgently need a power cord distribution device for surgical equipment, so as to solve the problem in the prior art that there is a lack of power cord distribution devices for storing and organizing the power cords of medical equipment, which leads to equipment damage and medical safety hazards.
