The body 32 is provided in a cylindrical tubular shape so that the endoscope 34 and the energy providing unit 36 can be accommodated. In addition, the body 32 is provided with a flexible material so as to have flexibility according to the shape of the organ or abdominal cavity inside the human body, and is provided with a biocompatible material that is harmless to the human body. For example, the body 32 is made of a biocompatible silicone material.

The endoscope 34 is formed of an optical fiber and disposed inside the catheter 30 along the longitudinal direction of the catheter 30. The endoscope 34 is optically connected to the image display unit 12 of the surgical unit 10 to photograph the inside of the human body.

The energy providing unit 36 is provided with the optical fiber like the endoscope 34 and is disposed inside the catheter 30 along the longitudinal direction of the catheter 30. That is, the energy providing unit 36 is accommodated in the catheter 30 so as to be parallel to the endoscope 34. The energy provider 36 is optically connected to the energy generator 14 to irradiate the laser oscillated from the energy generator 14 to the outside of the catheter 30. Here, the energy providing unit 36 includes an optical fiber for guiding and irradiating a laser from the energy generating unit 14 and a cooling passage for cooling high temperature heat from the optical fiber by surrounding the optical fiber.

The first blocking portion 52 is accommodated in the catheter 30, and the second blocking portion 54 is accommodated in the connecting portion 16. The first blocking unit 52 is an embodiment of the present invention, and is composed of a circuit including a fuse. In addition, the second blocking unit 54 receives electricity from the first blocking unit 52 and transmits the electricity to the power detecting unit 70. Here, when the first connection of the first blocking portion 52 and the second blocking portion 54, that is, the first connection of the surgical unit 10 and the catheter 30, the first blocking portion 52 and the second blocking portion 54 ) Is energized. On the other hand, when the electrical connection between the first blocking portion 52 and the second blocking portion 54 is cut off, that is, when the surgical unit 10 and the catheter 30 are separated, the fuse of the first blocking portion 52 is disconnected. In this way, the fuse of the first blocking portion 52 is disconnected, so that the electrical connection between the first blocking portion 52 and the second blocking portion 54 is permanently interrupted.

The power detector 70 detects the power provided from the second blocking unit 54. The power detection unit 70 transmits an operation signal to the control unit 90 when power is supplied from the second blocking unit 54. On the contrary, the power detecting unit 70 does not transmit an operation signal to the control unit 90 when power is not provided from the second blocking unit 54. The surgical unit 10 operates according to the presence or absence of a signal transmitted from the power detecting unit 70 to the control unit 90.

The controller 90 applies an operation control signal to the surgical unit 10 based on the signal from the power detection unit 70. That is, the controller 90 applies a control signal to operate the surgical unit 10 when a signal is transmitted from the power detection unit 70. At this time, since the surgical unit 10 and the catheter 30 are the first connection, the first blocking portion 52 and the second blocking portion 54 are electrically connected to each other.

On the other hand, the control unit 90 controls so that any one of the image display unit 12 and the energy generating unit 14 of the surgical unit 10 does not operate unless a signal is transmitted from the power detection unit 70. By the operation of the control unit 90, the surgical device 1 using the surgical energy is not operated.

Looking at the operation of the surgical device 1 using the energy for surgery according to the first embodiment of the present invention by such a configuration as follows.

First, the connecting portion 16 and the catheter 30 of the surgical unit 10 is connected. Then, the first blocking portion 52 of the catheter 30 and the second blocking portion 54 of the connecting portion 16 are electrically connected to each other. The second blocking unit 54 receives a power source, for example, a voltage of 3V to 5V according to the energization of the first blocking unit 52, and is sensed by the power detecting unit 70. The power detector 70 transmits a signal to the controller 90 when a voltage is detected from the second interrupter 54. The controller 90 determines that the surgical unit 10 and the catheter 30 are connected when a signal is applied from the power detection unit 70, and controls the operation of the surgical unit 10.

However, when the connecting portion 16 and the catheter 30 of the surgical unit 10 are separated from each other by the user, electricity is not permanently generated by the circuit of the first blocking portion 52. That is, even when the first blocking portion 52 and the second blocking portion 54 are reconnected, the first blocking portion 52 and the second blocking portion 54 are not energized with each other. As such, even when the first blocking unit 52 and the second blocking unit 54 are interconnected, the voltage is not sensed by the power detecting unit 70, so that the control unit 90 is configured to operate the surgical unit 10. It does not generate the necessary control signal.

Surgical device 300 using the surgical energy according to the second embodiment of the present invention, unlike the first embodiment, does not include a catheter 30 for receiving the endoscope 330 and the energy providing unit 340. . The endoscope 330 and the energy providing unit 340 of the surgical device 300 using the surgical energy according to the second embodiment of the present invention may be inserted into the human body individually.

The surgical unit 320 includes an image display unit 322, an energy generator 324, a first connector 326, and a second connector 328. The first connector 326 is connected to the endoscope connector 334 of the endoscope 330, which will be described later, and the second connector 328 is connected to the energy connector 344, which will be described later.

The endoscope 330 includes an endoscope 332 which is made of an optical fiber and is optically connected to the image display unit 322, and an endoscope connector 334 that is connected to the first connector 326. Since the endoscope 330 is inserted into the human body, the endoscope 330 is made of a flexible material and a biocompatible material. The endoscope 330 is inserted into the human body separately from the energy providing unit 340. The endoscope connector 334 is optically connected to the first connector 326. That is, the endoscope connecting portion 334 and the first connecting portion 326 are optically connected because they do not include the blocking portion 350 and the power receiving portion 360 that are electrically connected. However, although the blocking unit 350 and the power receiving unit 360 of the second embodiment of the present invention are accommodated in the energy connecting unit 344 of the second connecting unit 328 and the energy providing unit 340, the first connecting unit 326 ) And the endoscope connection 334.

The breaker 350 is received in the energy contact 344. The blocking unit 350 is electrically connected to the power receiving unit 360 accommodated in the second connector 328. Of course, the blocking unit 350 is electrically connected only at the first connection with the power receiving unit 360, and is electrically shorted when reconnecting. The blocking unit 350 has the same circuit configuration as the first embodiment of the present invention, thereby permanently interrupting the electrical connection when disconnecting from the power receiving unit 360.

The power receiver 360 is accommodated in the second connector 328. The power receiver 360 is electrically connected to the breaker 350 to generate a voltage. For example, the power receiver 360 generates a voltage of 3V to 5V.

The power detector 370 transmits a signal to the controller 390 according to the voltage detection of the power receiver. The controller 390 applies an operation control signal to the energy generator 324 when a signal is transmitted from the power detector 370. On the contrary, the controller 390 does not apply an operation control signal to the energy generator 324 unless a signal is transmitted from the power detector 370. Here, since the endoscope 330 and the image display unit 322 are optically connected, the controller 390 continuously applies an operation control signal to the image display unit 322.

Looking at the operation of the surgical device 300 using the surgical energy according to the second embodiment of the present invention by such a configuration as follows.

When the second connector 328 and the energy connector 344 are initially connected, the breaker 350 and the power receiver 360 are electrically connected to each other. Then, the power detector 370 detects the voltage received by the power receiver 360, and the power detector 370 transmits a signal to the controller 390. The controller 390 applies an operation control signal of the energy generator 324 based on the signal from the power detector 370.

On the other hand, when the second connection portion 328 and the energy connection portion 344 are separated, the electrical connection is permanently blocked even when the breaker 350 and the power receiver 360 are reconnected by the circuit operation of the breaker 350. . Then, the controller 390 does not apply the operation control signal to the energy generator 324.

Thus, by controlling the operation of the surgical unit by electrical connection and disconnection in accordance with the detachable connection of the energy supply unit and surgical unit providing the surgical energy, the energy supply unit can be used for one-time use, thus eliminating the sterilization process of the energy provider and In addition, hygiene safety during surgery can be improved.
