DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rechargeable medical device provided with a battery capable of charging a medical instrument such as a surgical instrument or an endoscope, and more particularly, this medical instrument is suitable for sterilization such as autoclave sterilization. The present invention relates to a rechargeable medical device.

[0002]

2. Description of the Related Art Various types of medical instruments such as electrically driven surgical instruments are conventionally known. For example, an ultrasonic surgical apparatus for incising and coagulating a living tissue using ultrasonic vibration,
An electric scalpel device that incises and coagulates living tissue using high-frequency power, an ultrasonic suction tool that uses ultrasonic vibration to crush and suck living tissue, and a living body that uses the rotational force of a drill or the like There is an ablation device for crushing tissue. Further, recently, a battery-type medical instrument with improved operability has been proposed in which a battery for driving the treatment instrument is mounted on an electrically-driven treatment instrument, thereby removing a power cable. As a battery-type medical device, a battery-type endoscope provided with a light source driven by a battery is also known. As an example of such a battery-type medical device, 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 the drill. A cutting device having a configuration in which a motor and a battery for supplying power to the motor are provided in a grip portion is shown. By the way, in such a medical device, it is required to surely sterilize the medical device in order to prevent an infectious disease or the like through the medical device. Therefore, in using medical instruments in surgery or examination, sterilization by a sterilizer such as an autoclave sterilizer or a washing device is performed in advance. Autoclave sterilization is sterilization using high-temperature, high-pressure steam, and is based on US standard ANS.
In I / AAMIST 37-1992, 13
It is specified to be exposed to steam at 2 ° C. for 4 minutes.

[0003]

However, in the case of a battery-type medical device, if the battery is replaced when the remaining power becomes insufficient, when the remaining power becomes insufficient after disinfection, the medical device may be used. The operability was poor because the battery was replaced while taking considerable care to maintain the sterile condition of the instrument. Therefore, such a problem can be avoided by using a rechargeable medical device configured to be able to charge while a rechargeable battery is loaded. However, when the medical device is rechargeable, it is required that not only the medical device but also the charging device to be contacted by the medical device can be sterilized, but the conventional charging device is generally not sterilizable. Did not. If the charging device cannot be sterilized, the sterilization state of the medical device will not be maintained during charging, and after the medical device has been charged, the time and labor required to perform the sterilization process again will be reduced. There was a problem that the equipment could not be used immediately. In addition, in the case of a rechargeable medical device, in performing surgery or examination, not only sterilization of the medical device but also extra time for charging the battery is required, resulting in poor work efficiency. The present invention has been made in view of the above circumstances, while maintaining the sterilization state of the medical device or performing a sterilization process,
In addition, the rechargeable battery can be charged while the battery is loaded in the medical device, thereby reducing the time required for sterilization and improving work efficiency, and enabling the medical device to be used immediately after charging. It is intended to provide a medical device.
