Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
It is to be noted that, unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the invention pertains.
As shown in fig. 1-6, an ultrasound and high frequency energy integrated dual mode system comprises a surgical instrument 1, a main machine 2 and a transducer;
an ultrasonic energy channel A, a high-frequency energy channel B, ultrasonic buttons 1-3 and high-frequency buttons 1-4 are integrated on the surgical instrument 1;
the ultrasonic buttons 1-3 and the high-frequency buttons 1-4 are used for controlling the host 2 to output ultrasonic energy and high-frequency energy respectively, and the host 2 can output frequency, voltage and power;
the output ultrasonic energy passes through an ultrasonic energy channel A acting on the tissue and is separated from the tissue through the ultrasonic vibration of the wave guide rod 5 and the clamp gasket 9-1;
the ultrasonic energy path A is a conducting loop formed by electrically connecting a host 2, a conducting ring 3 in the transducer 10 and the positive and negative electrodes of piezoelectric ceramic 10-1, the transducer 10 comprises piezoelectric ceramic 10-1, an amplitude transformer 4 and the conducting ring 3, and the amplitude transformer 4 is connected with a waveguide rod 5;
the output high-frequency energy realizes tissue closure through a high-frequency energy channel B acting on the tissue;
the high-frequency energy path B is a conducting loop which is sequentially and electrically connected with the host 2, the conducting strip 6, the thrust rod 7, the outer tube 8, the clamp 9, the tissue, the waveguide rod 5 and the amplitude transformer 4 and returns to the COM end;
the ultrasonic energy output end and the high-frequency energy output end are provided with respective interfaces at the host end and are switched by a relay;
the ultrasonic energy path A and the high-frequency energy path B are connected with the same port of the host machine 2 and return to the host machine.
The ultrasonic energy and the high-frequency energy are integrated on the same host and the surgical instrument, and the energy of two different working frequencies is effectively integrated, so that the dual-mode (the switchable output mode that the ultrasonic energy and the high-frequency energy are integrated) work which can emit two different frequencies and can meet respective working requirements is realized;
typically, the operating frequency range of the ultrasonic energy is 20KHz to 60KHz, and the operating frequency range of the high frequency energy is 200KHz to 600KHz.
In the above, the horn 4, the waveguide rod 5, the thrust rod 7, the inner tube 11, the outer tube 8, and the clamp 9 all have conductivity, and the clamp pad 9-1 is an insulating sheet.
Further, when working with high frequency energy, because the inner tube 11, the outer tube 8 and the clamp 9 are the energy output poles, and the other pole is the waveguide rod 5, the gap between the waveguide rod 5 and the inner tube 11 is small, and in order to make them work normally, it is necessary to avoid direct short circuit. Therefore, the direct short circuit is effectively prevented by adopting the following structure:
the first mode is as follows: the inner wall of the inner tube 11 is coated with an insulating coating. Because the inner pipe is longer, in order to ensure that the inner side of the pipe wall is adhered with the coating, the simple spraying mode can not meet the requirement. The coating is generally prepared by a CVD (chemical vapor deposition) process, which is a liquid immersion method and can ensure that the coating is uniformly attached to the inner wall. The insulating coating type can be selected from macromolecule coatings, and the following is recommended to be used: PTFE (polytetrafluoroethylene), PI (polyimide), PAI (imide), and optionally the thickness of the insulating coating is 0.002mm-0.20mm, so that the pressure resistance can be more than 1000V.
The second way is shown in fig. 8: a polytetrafluoroethylene sleeve 12 is arranged between the waveguide rod 5 and the inner tube 11, and the waveguide rod 5 is inserted in the polytetrafluoroethylene sleeve 12. The teflon sleeve 12 is designed to still retain the head support ring in support. Optionally, the polytetrafluoroethylene sleeve 12 has a wall thickness of 0.05mm to 0.25mm. The polytetrafluoroethylene sleeve can be replaced by PI (polyimide), PU (polyurethane), PE (polyethylene) and other extruded pipes with good insulating property.
The third approach is shown in fig. 9: a silica gel support ring 13 is arranged between the wave guide rod 5 and the inner tube 11, and the wave guide rod 5 is inserted in the silica gel support ring 13. The inner tube 11 and the waveguide rod 5 are directly added outside and inside the silica gel support ring 13, and a plurality of support rings are required according to length confirmation, so that mutual contact is avoided and a circuit short circuit is caused.
Based on the scheme as follows: materials selected include, but are not limited to: the material of the waveguide rod 5 is titanium alloy, the material of the inner tube 11 and the material of the outer tube 8 are both SS304 stainless steel, the material of the thrust rod 7 is aluminum alloy or stainless steel, the material of the amplitude transformer 4 is aluminum alloy, the material of the clamp 9 is 17-4SS stainless steel, and the material of the clamp gasket 9-1 is PTFE.
As a possible implementation, as shown in fig. 10, the host 2 includes a digital signal processor 2-1, an analog-to-digital converter 2-2, a digital-to-analog converter 2-3, a voltage adjustable controller 2-4, a transformer 2-5, an LC circuit 2-6, a relay K12-7, and a relay K22-8; the analog-to-digital converter 2-2 is connected with the digital signal processor 2-1, the digital signal processor 2-1 is connected with the digital-to-analog converter 2-3, the digital-to-analog converter 2-3 is connected with the voltage adjustable controller 2-4, the voltage adjustable controller 2-4 is connected with the LC circuit 2-6 through the transformer 2-5, the LC circuit 2-6 is connected with the relay K12-7, the relay K12-7 is connected with the relay K22-8, the relay K22-8 controls the switching of the US output port 2-9 and the RF output port 2-10, and the digital signal processor 2-1 is connected with the transformer 2-5 through the MOS switch.
In the embodiment, the DSP/ARM controls PWM1 or PWM2 to control the output frequency change through the MOS switch, the ultrasonic energy frequency range is adjusted to be 20KHz-60KHz, the high-frequency energy output range is 200KHz-600KHz, in addition, the DAC can adjust the output voltage through a voltage-adjustable controller (BUCK-BOOST CONTROLLER), the energy is boosted through a transformer 2-5 and is adjusted to be sine output through an LC circuit 2-6, the ultrasonic energy and the radio-frequency energy are switched through 2 relays, the LC circuit is switched through a relay K12-6 to meet the requirement of the output frequency, the output port is switched through a relay K22-7, and US (ultrasonic energy) and RF (high-frequency energy) have independent output ports and share a com port.

When a high-frequency button 1-4 is pressed, a digital signal processor 2-1 receives signals, the signals are adjusted to be sine output signals through a voltage adjustable controller 2-4, a transformer 2-5 and an LC circuit after being processed, a relay K12-6 switches the LC circuit to meet the requirement that a DSP/ARM controls PWM1 or PWM2 to control output frequency (200 KHz-600KHz frequency) through an MOS switch, the signals are switched to an RF output port 2-10 through a relay K22-8 to output high-frequency energy, a waveguide rod 5 and a clamp 9 form a double pole of a high-frequency path through a high-frequency energy path B, the current passes through tissues and heats the tissues to denature the tissues to form a closed band, the tissues are closed, the high-frequency button is released, and the ultrasonic energy is stopped from being output. In the high-frequency working process, the impedance of the tissue can be calculated in real time according to the sampling result of the ADC, and the output voltage and power can be adjusted in real time by the host according to the feedback of the impedance of the tissue.
