Embodiment Construction

[0020] Embodiments of the present invention will be described below with reference to the drawings. figure 1 It is a diagram showing a schematic configuration of an electrosurgical system to which the present invention is applied. Connected to the electrosurgical device 1 through the flexible wires 6a to 6d are respectively: a power cord 2; an electric scalpel 3 for treating the patient according to the high-frequency energy provided by the electrosurgical device 1; installed on the patient's leg or back, etc. The pole plate 4 on the top; and the foot switch 5 that inputs the high-frequency output indication. The tip portion of the electric scalpel 3 has an electrode portion 7 . The electrode portion 7 is made of SUS304 (stainless steel S304) and is conductive.

[0021] A force sensor 8 (here, a strain gauge) is attached to a part of the insulating cover 9 of the electric scalpel 3 to detect the force applied to the tip of the electric scalpel 3 . figure 2 It is a cross-se...

Abstract

The present invention provides a medical apparatus which has a treatment device for treating an imaging object. An energy supply section supplies energy to the treatment device to drive it. A sensor acquires information on conditions of the treatment device. An energy change detection section detects whether the magnitude of the energy supplied to the treatment device has changed. A control section controls drive of the sensor based on the result of detection obtained by the energy change detection section.

Description

technical field [0001] The present invention relates to a medical device having a sensor for obtaining information on the state of a treatment tool. Background technique [0002] Endoscopic surgery is widely practiced because it can approach an affected area without making a large incision of the patient's body, that is, it is so-called low-invasiveness. As the treatment tools used in this case, there are high-frequency treatment tools that perform incision and coagulation using high frequency or electric current, and energy treatment tools such as electric scalpels. These energy management tools are widely used in surgical procedures including endoscopic surgery because they do not need to suppress bleeding and do not need to use high force to cut. These energy treatment tools are sometimes equipped with sensors that obtain information about the state of the treatment tool. [0003] For example, Japanese Patent Application Laid-Open No. 2000-227367 discloses the following...
