Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a surgical device equipped with an ultrasonic scalpel and an electric scalpel.

[Prior Art] As a surgical device, an ultrasonic scalpel transmits ultrasonic vibrations to a probe to crush, emulsify, and suction remove tissues. It has the characteristic that relatively elastic tissue can be preserved without being removed.

On the other hand, an electric scalpel is a device that can perform incision or hemostatic coagulation by passing a high-frequency current (several hundred KHz to several tens of MKHz) between the active electrode and the return electrode and concentrating the current at the active electrode. , widely used in surgical procedures.

2. Description of the Related Art Conventionally, devices have been known in which an ultrasonic scalpel and an electric scalpel can be used in combination to take advantage of their respective characteristics. For example, US Pat. No. 4,249,901 makes it possible to selectively supply and use an ultrasonic scalpel signal and an electric scalpel signal to one handpiece by changing a switch.

Further, WO39102725 provides a high-frequency scalpel device and an electric scalpel device, and allows an electric knife signal to flow from the high-frequency scalpel handpiece. Further, a hand switch is provided on the high-frequency scalpel I/end bead, and a connection cord to an electric scalpel device is provided so that the high-frequency scalpel handpiece can be used as a handpiece with a switch for electric scalpels.

[Problems to be Solved by the Invention] However, the above-mentioned USP 4249901 is designed so that it can be used by selectively supplying an ultrasonic scalpel signal and an electric scalpel signal to one handpiece. When using an electric knife, it is not possible to simultaneously apply an electric scalpel signal to coagulate bleeding from a capillary while proceeding with the surgery. Further, WO39102725 has a built-in vibrator in the high-frequency scalpel handpiece, so it is heavier than the electric scalpel handpiece, and it is difficult to perform detailed hemostasis and incision operations like the electric scalpel. Furthermore, since the electric scalpel device is integrated with a high-frequency scalpel, if it is used alone as an electric scalpel handpiece, it is necessary to prepare another electric scalpel device exclusively for it, or use the high-frequency scalpel during surgery. There is the inconvenience of having to exchange the connection cord for the electric scalpel handpiece and the electric scalpel handpiece that you want to use.

This invention was made in view of the above-mentioned circumstances, and its purpose is to provide a surgical operating device that can use a high-frequency scalpel and an electric scalpel alone or in combination, and that facilitates surgery and is highly safe. Our goal is to provide the following.

[Means and effects for solving the problem] In order to achieve the above object, the present invention provides an ultrasonic scalpel device with a first hand piece for an ultrasonic scalpel capable of outputting an electric knife signal, and also includes a connector. A second hand piece with a hand switch for electric scalpel is connected to this connector, so that the first hand piece and the second hand piece can be selectively used, and either one of the hand pieces can be used. A control means is provided for detecting the output of the hand piece and disabling the other hand piece when the other hand piece is used.

For example, even if the hand switch of the second hand piece is accidentally operated while the first hand piece is being used with an electric scalpel signal flowing through it, based on the detection result by the output detection means,
Unexpected output may occur from the second handpiece.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

Figures 1 and 2 show a first embodiment.
The figure shows a schematic configuration of a surgical operating device. 1 is an ultrasonic scalpel device, and 2 is an electric scalpel device. The ultrasonic scalpel device 1 is provided with a first connector 3, and an ultrasonic scalpel hand piece 4 as a first hand piece is connected to the first connector 3. Then, ultrasonic vibrations can be transmitted to the probe 5 of the ultrasonic scalpel handpiece 4 to ablate tissue.

The ultrasonic scalpel device W1 and the electric scalpel device W2 are connected by a connection cord 6, and an electric scalpel signal from the electric scalpel device 2 can be transmitted to the ultrasonic scalpel handpiece 4 via the first connector 3. It looks like this. Further, the ultrasonic scalpel handpiece 4 is provided with a hand switch 7, which allows the electric knife signal from the probe 5 to be turned on and off.

Further, the high-frequency scalpel device 1 is provided with a second connector 8 . An electric scalpel handpiece 9 is connected to this second connector 8, but it is normally connected to the third connector 1° of the electric scalpel device 2 so that it can be used as an electric scalpel. Further, the electric scalpel device 2 is provided with a patient electrode plate 11 . However, since the connection cord 6 is connected to the third connector 10, the electric scalpel handpiece 9 is connected to the second connector 8, and the electric scalpel signal is connected to the hand switch provided on the electric scalpel handpiece 9. 12 allows it to be turned on and off. In addition, the ultrasonic scalpel W1 has a foot switch 1.
3 is provided so that the ultrasonic scalpel signal can be turned on and off.

As shown in FIG. 2, the ultrasonic scalpel device 1 is provided with an ultrasonic oscillator 14, and the electric scalpel device 2 is provided with a high frequency oscillator 15. Inside the ultrasonic scalpel device 1 are a hand piece 4 for an ultrasonic scalpel and a hand piece 9 for an electric scalpel.
Output detection circuits 16, 17 and 18 are provided as output detection means for detecting the states of the hand switch 7.12 and the foot switch 13, which control on/off of signals to be supplied to the circuit. That is, the output detection circuit]
6 indicates the state of the hand switch 7 for outputting the electric knife signal from the hand piece 4 for ultrasonic scalpel, and the output detection circuit 17 indicates the state of the hand switch 9 for outputting the electric knife signal from the hand piece 9 for electric knife. However, the output detection circuit 18 has a function of detecting the states of the foot switches 13 for causing the ultrasonic scalpel handpiece 4 to ultrasonic vibration. The detection results of these output detection circuits 16, 17 and 18 are manually input to the control device 19, and the control device 19
are switches 20.21.22 that open and close signals to the ultrasonic scalpel handpiece 4 and the electric scalpel handpiece 9;
and 23.

For example, when the foot switch 13 is turned on and the output detection circuit 18 detects that the ultrasonic scalpel handpiece 4 is performing ultrasonic resection, the control device 19 controls the It has a function of controlling so that even if the switch 12 is turned on, the switch 22 is not turned on, that is, the electric knife signal is not output. In this case, when the ultrasonic scalpel handpiece 4 outputs an electric scalpel signal to use the functions of an ultrasonic scalpel and an electric scalpel at the same time, if the hand switch 7 of the ultrasonic scalpel handpiece 4 is turned on, the switch is turned on. 21 is turned on, the switch 23 is turned on and an electric scalpel signal is also output from the ultrasonic scalpel handpiece 4.

On the other hand, the hand switch 12 of the electric scalpel handpiece 9
When the output detection circuit 17 detects that the switch 22 and the switch 23 are turned on and used as an electric scalpel signal, the switch 7 of the ultrasonic scalpel knife bead 4 is turned on. Even if the foot switch 13 is turned on, the switch 21 will not be turned on, and the switch 20 will not be turned on even if the foot switch 13 is turned on. Therefore, the ultrasonic scalpel handpiece 4 becomes unusable.

In this way, the output is prevented from being output from a handpiece other than the handpiece actually held by the operator, so safety is high.

Furthermore, the ultrasonic scalpel handpiece 4 can be used both as an ultrasonic scalpel and as an electric knife, and can simultaneously output an ultrasonic scalpel signal and an electric knife signal. Furthermore, the electric scalpel handpiece 9 can be used while being connected to the second connector 8 of the ultrasonic scalpel device fl, allowing the operator to quickly respond to surgical conditions. Furthermore, according to this first embodiment,
Existing electric scalpel handpieces can be combined as long as their output can be controlled by a hand switch, resulting in a highly versatile system.

FIG. 3 shows a second embodiment, and the same components as those in the first embodiment are given the same numbers and their explanations will be omitted.

The ultrasonic scalpel device 1 is provided with an output detection circuit 25 that detects the state of the hand switch 7 of the ultrasonic scalpel handpiece 4 and an output detection circuit 26 that detects the state of the hand switch 12 of the electric scalpel handpiece 9. ing. Furthermore, a prohibition signal line 27 is connected between these output detection circuits 25 and 26 and the ultrasonic oscillator 14 to transmit each state. Further, the ultrasonic scalpel device 1 is provided with relay circuits 28 and 29, which transmit the electric scalpel signal from the high frequency oscillator 15 in the electric scalpel device W2 to the ultrasonic scalpel handpiece 4 and the electric scalpel handpiece 9. It is designed to be selectively supplied. That is, each of the relay circuits 28 and 29 has a first contact 28a.

29a and second contacts 28b, 29b,
It is connected to be turned on and off by the output detection circuits 25 and 26.

Further, the output signals of the output detection circuits 25 and 26 are input to the OR circuit 30, and the output side thereof is connected to the output control device f131 of the electric scalpel device 2 via the connection cord 6. The output control device 31 connects the electric knife signal from the high frequency oscillator 15 so that it is turned on and off.

Note that the ultrasonic oscillator 14 is turned on and off by a foot switch (not shown) or the like.

Therefore, when the second switch 12 of the electric scalpel/X-end bead 9 is turned on, the output detection circuit 26 is activated, the relay circuit 29 is activated, and the OR circuit 3
0, the output control device 31 in the electric scalpel device 2 is activated, and the high frequency oscillator 15 is activated.
operates and outputs the electric scalpel signal (for electric scalpel)
\An electric scalpel signal is output from the throat piece 9. In other words,
When the relay circuit 29 operates, the electric scalpel signal path to the ultrasonic scalpel/end bead 4 is connected to the first
The contact point 28g of the relay circuit 29 and the second contact point 29b of the relay circuit 29 are doubly disconnected. In addition, the output detection circuit 26
While in operation, a prohibition signal is transmitted to the output detection circuit 25 and the ultrasonic oscillator 14, and neither the ultrasonic scalpel signal nor the electric knife signal is transmitted to the ultrasonic scalpel handpiece 4.

On the other hand, the hand switch 7 of the hand piece 4 for ultrasonic scalpel
When turned on, the output detection circuit 25 is activated and the relay circuit 28 is activated. In this case, the electric scalpel signal to the electric scalpel handpiece 9 is doubly disconnected by the first contact 29a of the relay circuit 29 and the second contact 28b of the relay circuit 28. In addition, the output detection circuit 2
5 or while the ultrasonic oscillator 14 is operating, a +L signal is transmitted to the output detection circuit 26, and the hand switch 12 of the electric scalpel handpiece 9 is disabled, and even if the electric scalpel handpiece 9 is turned on, the electric scalpel handpiece 9 becomes unusable.

With this configuration, the electric knife path is reliably transmitted to only one of the handpieces, and since the relay circuit is provided with double contacts, for example, the relay circuit 28 may malfunction. Even if the hand switch 7 is operated, the electric scalpel signal is output from the ultrasonic scalpel hand piece 4, but when the hand switch 12 is turned on, the ultrasonic scalpel hand piece 4 However, the electric scalpel signal will not be output unexpectedly.

FIG. 4 shows a third embodiment, in which the output detection circuit for detecting the states of the hand switch 7 of the hand piece 4 for ultrasonic scalpel and the hand switch 12 of the hand switch 9 for electric scalpel is the same as that of the above embodiment. different.

The ultrasonic scalpel handpiece 4 and the electric scalpel handpiece 9 are designed to output two types of output from the electric scalpel device 2: CUT current for incision and C0AG current for coagulation and hemostasis.
Two hand switches 7a (COAG), 7b (CU
T), 12a (COAG) 12b (CUT)
It is equipped with 32 is a four-man powered NAND circuit, and 33 is a two-man powered NAND circuit. Four four-person powered NAND circuits 32 are provided, and the input and output of each circuit are connected in a sash pattern. Furthermore, four two-manpower NAND circuits 33 are provided, and the two combinations of the outputs of the four-manpower NAND circuits 32 are ORed.

Therefore, the circuit described above becomes a priority output circuit for the four hand switches 7a, 7b, 12a, and 12b, and for example, when the hand switch 7a is turned on, the output
is output, and its output inhibits the operation of the remaining three 4-person NAND circuits 32. That is, the hand switch 7a
is turned on, the other hand switches 7b, 12
a.

Even if 12b is turned on, the output O is held and no other outputs are output. As a result, four 4-person NAND
Only one of the outputs 0, P, Q, and R of the circuit 32 will be output, and by ORing this output,
The type of output light of the ultrasonic scalpel handpiece 4 and the electric scalpel handpiece 9 can be selected. Therefore, the danger of double operation of each hand switch can be reliably prevented.

FIGS. 5 and 6 show a fourth embodiment, which differs from the previous embodiment in the electric knife output selection circuit.

The ultrasonic scalpel device 1 is provided with relay circuits 34 and 35 to select the output light of the electric scalpel signal to the ultrasonic scalpel handpiece 4 and the electric scalpel handpiece 9. Furthermore, a relay circuit 36 turns on and off the output of the electric knife signal, and a control device 37
has the function of controlling the relay circuits 34, 35 and 36.

Therefore, when the hand switch 7 is turned on in order to output an electric knife signal from the ultrasonic scalpel handpiece 4, the contact 34 of the relay circuit 34
a is closed, and an ultrasonic scalpel signal path to the ultrasonic scalpel handpiece 4 is created.

After a certain period of time (1), the relay circuit 36 closes, the electric scalpel device 2 operates, and an electric scalpel signal is output.

When the hand switch 7 is turned off, the relay circuit 36 is opened at the time of falling, and after a certain period of time (t'), the relay circuit 34 is opened.
Open the contact 34a.

Similarly, when the hand switch 12 on the hand switch 12 side of the electric scalpel hand piece 9 is turned on, the contact 35a of the relay circuit 35 closes at the same time as the hand switch 12 starts up, and an electric scalpel signal path to the electric scalpel hand piece 9 is established. , an electric scalpel signal is output. When the hand switch 12 is turned off, the electric knife signal path is cut off.

In this way, the contacts 34a and 135a of the relay circuits 34 and 35 that open and close high-voltage and large-current electric scalpel signals can be protected. Therefore, contact 34a.

Accidents of welding of 35a can be prevented.

In addition, each of the above-mentioned fruit t! In example i, the ultrasonic scalpel device and the electric scalpel device were explained as separate units, but it is also possible to combine these devices or other surgical devices, such as a laser device or a microwave device. good.

A second hand piece with a female hand switch is connected, and the first hand piece and the second hand piece can be selectively used, and when either hand piece is used, its output is By providing a control means that detects this and disables the other handpiece, it is highly safe, and the high-frequency scalpel and electric scalpel can be used alone or in combination, allowing for faster surgery. This has the effect of allowing you to do this.
