Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a surgical device having a function of crushing cells using ultrasonic vibrations and a function of cauterizing cell tissue using high-frequency current.

The purpose of the present invention is to perform surgical operations that can emit the amplitude and power of ultrasonic vibrations capable of crushing cell tissues and high-frequency currents capable of cauterizing cell tissues in a wide range of biological tissue fields. The purpose is to provide equipment.

Conventionally, electric scalpels cauterize cell tissues and blood vessels such as capillaries at the same time, stopping bleeding during incision, and using ultrasonic vibrations to crush and cut cells to be removed without damaging blood vessels or nerves. It is known to do.

The present invention does not damage conventional blood vessels or nerves. <1.
A device using ultrasonic vibrations that can crush and cut the cells to be removed cauterizes the cell tissue and at the same time cauterizes blood vessels such as capillaries, and has the functionality of an electric scalpel surpassed above in order to eliminate defects in which bleeding cannot be stopped. It was equipped with a surgical device that uses sonic vibrations.

The present invention crushes biological tissue by ultrasonic vibrations generated by an ultrasonic transducer having an ultrasonic transducer made of an electrostrictive transducer or a magnetostrictive transducer; This is a surgical device characterized by having a horn and supplying a high frequency current to the horn to cauterize living tissue.

This can be used to quickly and reliably stop bleeding in other areas during the disruption of cell tissue by the ultrasonic vibration of the horn at the surgical site where blood vessels and nerves are concentrated after incision, and the surgical tool This eliminates the time required to change hands and reduces the time required for surgery.

The present invention will be described in detail below with reference to the accompanying drawings. In FIG. A horn (3) is attached to the tip of the ultrasonic transducer (2). The main body (1) includes an ultrasonic oscillation circuit section (
8), high frequency generation circuit section (9), and switching relay 00,a
It is composed of υ. The maximum rating value of the ultrasonic oscillation circuit section (8) is 50 to 500 W1, and the output frequency is 20 to 40 KI.
(The maximum rating value of the z1 high frequency generation circuit section (9) is 50 to 5.
00W, and the output frequency is preferably 1 to 10 MH2. In Figure 2, when disrupting cells by ultrasonic vibration,
The relay (lot) becomes conductive and the relay housing becomes open. In this state, ultrasonic vibrations are generated in the ultrasonic transducer (2), and the ultrasonic vibrations are transmitted by the horn (3). The ultrasonic amplitude is expanded and the cells are crushed by the horn (3). At this time, the ultrasonic amplitude of the horn (3) is preferably 50 to 250 μm. A high frequency current is supplied to the horn (3) to cauterize the cells. When performing hemostasis, relay aυ becomes conductive, and relay α (rei becomes open. Ultrasonic transducer (2) is 20 to 40 K). Ultrasonic vibration is performed at the frequency of IZ, so this Since ultrasonic vibrations are not generated in response to a high frequency current of 1 to 10 MHz, the high frequency current is supplied to the high frequency generating circuit (9) and the horn (3).

In FIG. 3, the shape of the pawn (3) is preferably of three types: a horn 03 with a right-angled end face, a horn α9 with an angled end face, and a horn α4) with a rectangular tip.
