Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surgical operation system having a function such as coagulation and incision by an electric knife and performing treatment such as incision using ultrasonic energy.

[0002]

2. Description of the Related Art Conventionally, various surgical devices for surgical operations have been developed. Among them are an ultrasonic scalpel device that cuts tissue while coagulating using ultrasonic vibration, and an electric scalpel device that coagulates or cuts by applying a high-frequency signal to living tissue from the probe tip.

Since these various surgical devices have their own advantages or disadvantages, surgery is performed by appropriately combining the respective surgical devices.

For example, Japanese Patent Application Laid-Open No. 9-38098 discloses that
It is disclosed that an ultrasonic surgical device is provided with a function of an electric scalpel so that a high-frequency current is passed from the tip of the probe so as to stop bleeding that is gradual or bleeding from a wall surface such as the abdominal wall.

Further, for example, Japanese Unexamined Patent Publication No. 11-318919 discloses a surgical operation apparatus in which a surgical operation apparatus using ultrasonic waves has a function of a bipolar electric knife.

To supply the electrosurgical knife signal to the handpiece, a cord is connected to the electrosurgical knife device and installed on the opposite side.
This can be done by connecting the plug to the connector provided on the handpiece.

By operating a foot switch provided in the electric scalpel device, an electric scalpel signal can be output from the tip of the ultrasonic probe.

This conventional example will be described with reference to FIG. Reference numeral 101 is an ultrasonic surgical apparatus, reference numeral 102 is a foot switch for turning on / off the ultrasonic output, reference numeral 103 is a monopolar electric scalpel device, reference numeral 104 is a foot switch for turning on / off the output of the electric knife, and reference numeral 105 is A handpiece for treatment with ultrasonic waves and an electric scalpel, reference numeral 106 is a hand switch provided on the handpiece, reference numeral 107
Is a counter plate, reference numeral 108 is an electric knife code for supplying the output of the electric knife device 103 to the handpiece 105, and reference numeral 109 is a connector means.

In this system, the handpiece 105 normally performs coagulation / incision by ultrasonic vibration, and the electric knife cord 108 is attached to the handpiece 105 as necessary.
By operating the foot switch 104 or the hand switch 106 by connecting to the connector 109 provided in, the hemostasis operation by the electric knife can be performed.

However, as described above, in order to operate the electric knife signal, two cords, the hand switch 106 and the electric knife cord 108, must be connected to the handpiece 105 each time.

On the other hand, when performing an endoscopic surgical operation using an ultrasonic surgical device or an electric scalpel device, a dedicated display means provided on a monitor showing an endoscopic image of the operating state of these devices or in the vicinity thereof The technology for displaying is disclosed.

[0012]

However, in the configuration as shown in each of the prior examples, the output of the ultrasonic surgical device and the output of the electric scalpel are operated by arranging the foot switches for each device. There was the complexity of having to do it.

Further, when displaying the status of these surgical devices on the monitor, there is usually only a choice between always displaying on the monitor and not displaying it. Therefore, if the user wants to obtain the information only when an error occurs, the information has to be displayed on the monitor at all times, so that the status is displayed even when the error does not occur.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a surgical operation system capable of improving operability.

[0015]

A surgical operation system according to the present invention is an ultrasonic transducer for generating ultrasonic vibration capable of treating a living tissue, and the ultrasonic vibration from the ultrasonic transducer is converted into the living tissue. To the handpiece, a high-frequency current generating means for generating a high-frequency current capable of treating the living tissue, and a connector means provided on the handpiece for connecting the high-frequency current generating means. A first contact provided on the connector means for inputting the high-frequency current generated by the high-frequency current generating means to the probe so that the probe can supply the high-frequency current, and the first contact provided on the handpiece. An openable and closable switch means to which one terminal is connected, a second contact provided to the connector means, to which the other terminal of the switch means is connected, Based on the conduction state between the contacts of the switch means, and comprises a control means for controlling said high-frequency current generating means.
