Description

The present invention relates to an ultrasonic incision coagulation apparatus capable of performing a treatment using a high-frequency current in addition to a treatment for removing or coagulating a living tissue by ultrasonic vibration.

In recent years, by inserting an elongated insertion portion into a body cavity, an internal organ in the body cavity is observed, and various treatments are performed under endoscopic observation as necessary.

As one of the methods for performing a therapeutic treatment under the endoscope observation, a treatment of sucking or grasping a living tissue and applying ultrasonic vibration to the sucked or gripped member to cut or coagulate the living tissue is performed. What you do is known.

For example, Japanese Patent Application Laid-Open No. Sho 62-127042 discloses an ultrasonic lithotripter in which a calculus is grasped and crushed by ultrasonic vibration. Japanese Patent Application Laid-Open No. 1-223944 discloses a surgical operation apparatus in which a living tissue is grasped and fixed by grasping forceps and incised by an ultrasonically vibrating probe. Further, Japanese Patent Application Laid-Open No. 1-223245 discloses a surgical operating apparatus in which a living tissue is adsorbed and fixed, and the incision is made with a scalpel that vibrates ultrasonically. Further, Japanese Patent Application Laid-Open No. 1-223248 discloses a surgical resection forceps in which living tissue can be efficiently resected by applying ultrasonic vibration to the resection forceps. Further, Japanese Patent Application Laid-Open No. 1-223949 discloses a surgical method in which a living tissue is fixed by a gripping means and a treatment is applied to the living tissue by a movable member to which ultrasonic vibration is applied, as in the above-mentioned Japanese Patent Application Laid-Open No. 1-223244. A surgical device is shown. In US Pat. No. 5,322,055, a gripping member is provided which is rotatable toward an ultrasonic probe. The ultrasonic probe and the gripping member grip living tissue and apply ultrasonic vibration to coagulate the living tissue. A clamp coagulation device and cutting system for an ultrasonic surgical instrument capable of being dissected is shown. In these devices for performing treatment using ultrasonic waves, the treatment can be performed while grasping the living tissue as in the case of using ordinary surgical forceps, so that a better treatment can be performed than in the case where the treatment is performed with a single probe.

On the other hand, a treatment instrument for endoscopic surgery as disclosed in Japanese Patent Application Laid-Open No. H6-179049 is generally used as a treatment device capable of performing treatment using a high-frequency current. Through the return section called the body electrode to perform treatment. This type of treatment tool had excellent hemostatic performance.

On the other hand, the treatment tool called bipolar disclosed in JP-A-6-30947 was of a type in which a high-frequency current circuit was incorporated between gripping members of a forceps portion. This type of treatment instrument is configured such that high-frequency current does not flow to unnecessary portions of the living tissue, electrically insulates the forceps member, and insulates the transmission member that drives the forceps member from the sheath. Each was provided with a power supply means.

However, in the above-described apparatuses for performing treatment using ultrasonic waves disclosed in JP-A-62-127042, JP-A-1-232944, JP-A-1-232948, and the like, an ultra-fine treatment is performed on a living tissue. Only treatment by sonic vibration could be performed. In general, treatment by ultrasonic vibration is inferior to hemostatic treatment by high-frequency current.Therefore, when urgently necessary to stop bleeding, the treatment device using ultrasonic vibration must be replaced with a treatment device using high-frequency current. It was not easy to use.

On the other hand, the treatment tool for endoscopic surgery disclosed in Japanese Patent Application Laid-Open No. H6-179049, which can perform a treatment using a high-frequency current, has a problem that a current may flow to an unnecessary portion of a living tissue. An endoscopic treatment tool that performs a treatment only with high-frequency current can perform treatment with high frequency current, and has good hemostasis performance, but has a large effect on living tissue, and may cause excessive cauterization.

For this reason, it is ideal for the operator who actually performs the treatment to perform the treatment by the ultrasonic vibration as much as possible and to perform the treatment by the high-frequency current only when necessary. It was impossible to perform treatment by ultrasonic vibration and to perform treatment by high-frequency current only when necessary.

In order to solve these problems, Japanese Patent Application Laid-Open Nos. Hei 3-111037, Hei 5-23348 and US Pat. No. 4,931,047 disclose an ultrasonic aspirator or the like which can use both ultrasonic vibration and high-frequency current. A sonic treatment device is shown. In these devices, a rod-shaped or spatula-shaped probe is pressed against a living tissue for treatment. For this reason, it is difficult to perform the treatment while securely holding the probe on the target living tissue, and it has been necessary to assist with a plurality of forceps or the like in order to perform a fine operation. However, even with operations that are not a problem in normal laparotomy, in endoscopic surgery, the use of forceps, which is a treatment instrument for multiple endoscopic surgical operations, causes many holes in biological tissue Therefore, there was a problem in terms of minimally invasive. Furthermore, it is difficult to perform a remote operation while observing an endoscopic image displayed on a monitor screen, and it is difficult to cooperate with a plurality of treatment tools. Was desired. Although the clamp coagulation apparatus and the cutting system disclosed in US Pat. No. 5,322,055 solve this problem, there is a problem that a treatment using a high-frequency current cannot be used together as described above.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and requires a single apparatus to coagulate or dissect a desired living tissue by using a single device without exchanging a treatment tool according to each treatment of coagulation, dissection and hemostasis. In addition, another object of the present invention is to provide an ultrasonic incision coagulation apparatus for performing a treatment using a high-frequency current having a high hemostatic ability.

The operation of the ultrasonic incision coagulation apparatus 1 configured as described above will be described.
First, the ultrasonic incision coagulation device 1 is made to face a target living tissue in a living body. Then, the movable member 4b of the operation unit 4 is operated so as to be in an open state, and the gripping member 6 is opened to the probe 5.

In addition, since treatment by ultrasonic vibration and treatment by high-frequency current can be performed simultaneously, treatment by ultrasonic vibration is performed as much as possible, and treatment by high-frequency current is performed only when necessary. Both effects of preventing tissue degeneration can be obtained.

Furthermore, when performing a treatment by passing a high-frequency current, the treatment is performed by passing the high-frequency current through the living tissue using an electrode plate, or the living tissue is grasped between the grasping member and the probe without using the electrode plate. The operator has a wider range of choices, for example, by applying a high-frequency current to the living tissue between the gripping member and the probe.
