Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an ultrasonic scalpel that can also be used as an electric knife.

[Conventional technology]

Ultrasonic scalpels concentrate ultrasonic energy on unnecessary tissue, crush or emulsify the tissue, and expel it to the outside. Because it can selectively remove tumors, stones, etc., it is widely used in surgical procedures. It has been applied in various fields and has shown excellent medical effects.

On the other hand, electric scalpel is also essential for surgical operations.
Not only is it effective for incising the skin and separating muscle and cartilage, but it is also extremely useful for hemostasis and coagulation at the surgical site.

However, in the past, it has often been necessary to use both in surgical operations and the like. However, since they are originally configured independently, it is necessary to interrupt the operation and use a different scalpel each time to change the scalpel, adjusting it according to the situation of the surgical field at that time. However, the adjustment takes time and effort, and as a result, it has become an obstacle to performing a quick, appropriate, and efficient surgery.

Furthermore, a drawback of conventional ultrasonic scalpels is that patients who come into contact with the tip of the tip may receive an electric shock, causing burns or other accidents. In other words, since chips are primarily required to be rigid, special composite steels such as titanium, chromium, titanium, and barium are often used, but since these are good electrical conductors, they are not susceptible to vibration. Electrical leakage from electrical equipment that rotates the tip is often conducted to the tip of the tip, causing an electric shock to the patient during surgery, and there is a strong need for countermeasures against this problem.

[Problem that the invention attempts to solve]

This invention was made in view of the actual situation,
If blood vessels are damaged and bleeding occurs during the stage of crushing and emulsifying tissue using an ultrasonic scalpel, this ultrasonic scalpel device is equipped with an electric scalpel that allows immediate hemostasis and coagulation, making it extremely easy to use. In addition to being equipped with the ability to convert from an ultrasonic scalpel to an electric scalpel, and from an electric scalpel to an ultrasonic scalpel, the tip's constituent materials This ultrasonic scalpel has been changed to a material with electrical insulation properties such as plastic, and the tip of the electric scalpel that protrudes from the tip is energized only when used as an electric scalpel, making the ultrasonic scalpel much safer. Its purpose is to provide.

[Means for solving problems]

In the present invention, the following measures are adopted to solve the problems. That is, a) an ultrasonic scalpel comprising a tip that is attached to the tip of a vibrator and whose vibrations are transmitted by the vibrator, b) the tip is made of an electrical insulator such as plastics or ceramics, and c) a tip. A tongue piece for an electric scalpel that can be energized is attached to a turn spring body fixed to the tip surface slightly behind the tip of the tip, and protrudes from the tip tip when the turn spring body is reversed. Female.

The above is the summary.

The present invention will be described below based on embodiments with reference to the drawings.

〔Example〕

FIG. 1 is a perspective view of essential parts showing an ultrasonic scalpel that also serves as an electric knife according to the present invention. The chip 1 attached to the tip of the vibrator 2 via a screw etc. is the vibrator 2.
transmitted to the vibrations of the Although not shown, the vibrator 2 is connected to an oscillator built into the main body.
The tip end surface 1a of the tip 1 is formed flat so as to be pressed perpendicularly to the target surface, and a hollow hole 1b is formed in the tip. The unnecessary tissue that has been collected and crushed or emulsified by the suction device is discharged to the outside. However, since these details are not directly related to the present invention, a detailed explanation will be omitted.

A feature of the present invention is that the chip 1 is made of an electrical insulator such as plastics or ceramics. Plastics suitable for the chip include, for example, polyacrylate, polyether sulfon or glass fiber reinforced plastics, and ceramics include, for example, alumina, magnesia,
It is composed mainly of oxides such as silica and has relatively high rigidity and good moldability. Both are electrically poor conductors, that is, insulators, and the vibrator 2
There is no possibility that electric leakage from sources such as the like will reach the tip of the tip and cause an electric shock to the patient.

Next, other important features of this invention are:
A tongue piece 3 for the electric knife tip extends from the tip of a turn spring body 4 fixed to the tip surface slightly behind the tip surface 1a of the tip 1. When the scalpel according to the present invention is used as an electric knife, the turn spring body 4 is turned over to the tip end surface 1a side as shown in FIG. Electricity is applied to the tongue piece 3 through the wire 5, and it is used for hemostasis, coagulation, etc. When the tongue piece 3 is used, it is turned back to its original position and the tip end surface can crush, emulsify, etc. again. .

[Effect of idea]

The present invention is based on the above configuration, and
First, since the chip is made of an electrical insulator,
The risk of electric shock to patients when using an ultrasonic scalpel is completely eliminated, and bleeding caused by damage to blood vessels caused by the use of an ultrasonic scalpel can be quickly stopped and coagulated, improving efficiency in surgical operations. This is an extremely useful device that can significantly improve safety and safety.
