Abstract

PROBLEM TO BE SOLVED: To provide a surgical instrument whose operability can be enhanced by making a surgical instrument smaller in size and lighter in weight, assuring a sufficient power capacity, and preventing entanglement of a power cable. SOLUTION: A battery 3 is freely detachably mounted in the battery holding part 11 of a battery holder 6 which can move slidably on a rail 5 mounted on a bed 4 and electric power is supplied from the battery 3 to a surgical instrument 2 via a power cable. The surgical instrument 2 can be miniaturized and made lightweight since it has no battery built in. Since the battery 3 is separated from the surgical instrument 2, a sufficient power capacity can be assured. Also, since the battery 3 is freely movable by the battery holder 6, the power cable can be shortened and prevented from being entangled whereby operability can be enhanced.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surgical apparatus characterized by an electric drive type surgical instrument or a means for supplying power to an endoscope.

[0002]

2. Description of the Related Art Various types of electrically driven surgical instruments have been conventionally known. For example, an ultrasonic surgical apparatus for incising and coagulating a living tissue using ultrasonic vibration, and heat using high-frequency electric power are used. An electrosurgical unit that dissects and coagulates the living tissue by using an ultrasonic device, an ultrasonic suction device that uses the ultrasonic vibration to crush and aspirate the living tissue, and a crushed and aspirated living tissue that uses a rotating drill There is an excision device, an ultrasonic trocar that punctures the opposite wall using ultrasonic vibration, and guides a surgical instrument into a body cavity. As an example of such an electrically driven surgical instrument, for example, in the first embodiment of Japanese Patent Publication No. 2-43501, a drill for crushing living tissue is provided at the tip of a probe, and a rotational driving force is supplied to this drill. FIG. 1 shows a cutting device having a configuration in which a gripping portion is provided with a motor to be driven and a battery for supplying power to the motor. Further, for example, in the second embodiment of Japanese Patent Publication No. 2-43501, a drill for crushing a living tissue is provided at the tip of the probe, and a motor for supplying a rotational driving force to the drill and the motor are provided for the grip portion. A cutting device having a configuration in which a power cable for supplying electric power to the motor from an external power source is provided in a grip portion is shown. For example, in Japanese Patent Application No. 10-107734, a connector for detachably connecting a surgical tool such as an electric scalpel, a drive circuit for driving the surgical tool, and a cable for receiving power supply from an external AC adapter. A surgical instrument having a configuration provided with is shown.

[0003]

However, when the battery is housed in the surgical instrument as in the first embodiment of Japanese Patent Publication No. 2-43501, the mobility of the surgical instrument is improved, but the battery is built into the surgical instrument. Therefore, if the surgical tool becomes heavy, the battery capacity is reduced to keep the size of the surgical tool small and the continuous use time is shortened, and if the battery runs out during the operation, it takes time to replace the battery. There was a problem that it took. Also, 2-43
As in the second embodiment of No. 501 and Japanese Patent Application No. 10-107734, when the power cable extends from the surgical instrument,
Although a large power supply capacity can be ensured and the weight of the surgical tool can be reduced, there is a problem in that the power cable is entangled during the operation, which complicates the operation and hinders the mobility of the surgical tool. The present invention has been made in view of the above circumstances,
It is an object of the present invention to provide a surgical apparatus capable of improving operability by reducing the size and weight of a surgical tool, securing a sufficient power supply capacity, and preventing a power cable from becoming entangled.

[0004]

According to one aspect of the present invention, there is provided an electric drive system for performing or observing a medical procedure in close proximity to a patient to be examined on a bed. A battery for supplying electric power to a surgical tool or an endoscope, a rail provided on the bed, and a battery holder movable along the rail and detachably holding the battery. I have.
