Description

Technical Field

[0001] The present invention relates to the technical field of surgical instruments, and in particular to an integrated surgical system suitable for large blood vessel surgery. Background Art

[0002] Ultrasonic surgical scalpels utilize an ultrasonic frequency generator to drive the handle and blade to produce ultrasonic vibrations at an ultrasonic frequency (55.5kHz) to perform surgical incisions. This vibration breaks protein hydrogen bonds within contacted tissue cells, causing ruptured blood vessels to coagulate and stop bleeding, simultaneously achieving both incision and closure. This results in high reliability and surgical safety. Currently, ultrasonic surgical systems are the world's leading essential auxiliary instruments for minimally invasive surgery and are a staple in large and medium-sized hospitals worldwide and in China. They are widely used in general surgery, obstetrics and gynecology, urology, and other procedures. When ultrasonic waves propagate through a medium, they produce mechanical, thermal, and acoustic responses. Ultrasonic surgical systems utilize these properties to induce mechanical, thermal, and cavitation effects on tissue, achieving the desired tissue incision and closure, thus achieving clinical application. While ultrasonic scalpels inflict minimal damage, making them suitable for delicate incisions, such as those involving capillaries, their slow cutting speed makes them unsuitable for procedures requiring extensive muscle dissection.

[0003] However, for large blood vessels, their high blood pressure and thin vessel walls create a high risk of bleeding, making simultaneous coagulation with an ultrasonic scalpel unsuitable. Therefore, a high-frequency coagulation scalpel is used. Using this scalpel, at least three fingers of one hand are first used to clamp the blood vessel. This creates impedance within the tissue under the action of high-frequency waves, causing water molecules within the target tissue to instantly oscillate and vaporize under the action of high-frequency / radiofrequency waves, causing cell rupture and evaporation. At a constant temperature of 40°C, this scalpel achieves hemostasis and electrocoagulation. The remaining fingers of the hand are then used to push the blade to cut, completing the coagulation and cutting of the large blood vessel. However, a key issue with using this scalpel is that it's not known when the blood in the vessel will coagulate. Furthermore, the cutting speed is not very fast. Furthermore, operating multiple function buttons with one hand requires multiple steps for each closing and cutting operation, making it very inconvenient to use the entire hand. Summary of the Invention

[0004] In view of this, the present invention provides an ultrasonic high-frequency surgical integrated system ultrasonic scalpel that can solve the above technical problems.

[0005] A surgical integrated operation system suitable for large blood vessel surgery includes a high-frequency / radio frequency generator, an ultrasonic scalpel generator, and a control module that controls the working states of the high-frequency / radio frequency generator and the ultrasonic scalpel generator. The control module includes a coagulation threshold setting unit, a detection control unit, an electrocoagulation start-up and shut-down unit, and an ultrasonic scalpel start-up and shut-down unit. The coagulation threshold setting unit is used to set the coagulation threshold when the large blood vessel coagulates. The coagulation threshold includes a frequency change threshold and an impedance change threshold. The detection control unit is used to control the ultrasonic scalpel generator to detect the coagulation status value of the large blood vessel. The coagulation status value includes a frequency change amount and an impedance change amount. The electrocoagulation start-up and shut-down unit is used to control the high-frequency / radio frequency generator to turn on for electrocoagulation when the detection control unit controls the ultrasonic scalpel generator to turn on, and to turn off the high-frequency / radio frequency generator when the frequency change amount and impedance change amount output by the detection control unit are greater than the frequency change threshold and the impedance change threshold, respectively. The ultrasonic knife starting and closing unit is used to start the ultrasonic knife generator for ultrasonic cutting when the frequency change and impedance change output by the detection control unit are respectively greater than the frequency change threshold and the impedance change threshold.

[0006] Furthermore, the surgical integrated surgical system suitable for large blood vessel surgery also includes a tool assembly, which includes an outer tube, an inner tube inserted in the outer tube, a tool rod inserted in the inner tube, a clamping nozzle rotatably arranged on the inner tube, at least two insulating spacer rings arranged between the inner tube and the tool rod, and a transducer, and the ultrasonic knife generator is electrically connected to the transducer.

[0007] Furthermore, the high frequency / radio frequency generator includes a positive output terminal and a negative output terminal, the positive output terminal is electrically connected to the knife rod, and the negative output terminal is electrically connected to the clamping nozzle, and the knife rod and the clamping nozzle form a pair of radio frequency cutters.

[0008] Furthermore, the surgical integrated operating system suitable for large blood vessel surgery also includes a negative plate electrically connected to the high-frequency / radio frequency generator, and the high-frequency / radio frequency generator includes a positive output end and a negative output end. The positive output end is electrically connected to the knife rod, and the negative output end is electrically connected to the negative plate. The knife rod and the negative plate form a pair of radio frequency cutters.

[0009] Furthermore, when the high frequency / radio frequency generator is turned on alone, the knife rod and the negative plate or the clamping nozzle form a pair of radio frequency cutters.

[0010] Furthermore, the surgical integrated operating system suitable for large blood vessel surgery also includes an integrated converter for switching the working states of the high-frequency / radio frequency generator and the ultrasonic scalpel generator. The integrated converter is used to control the working states of the high-frequency / radio frequency generator and the ultrasonic scalpel generator under the control of the control module.

[0011] Furthermore, the high-frequency / radio frequency generator, the ultrasonic knife generator, and the integrated converter are all independent components.

[0012] Furthermore, when the ultrasonic scalpel generator is turned on alone, the scalpel rod forms an ultrasonic scalpel. When the high-frequency / radio frequency generator and the ultrasonic scalpel generator are turned on at the same time, the scalpel rod is used as a radio frequency cutter and an ultrasonic scalpel at the same time.

[0013] Furthermore, the integrated converter includes a button selection switch arranged on the accommodating cavity.

[0014] Furthermore, the integrated converter includes a negative output unit, an integrated output unit, and a key drive selection unit, wherein the key drive selection unit is used to control the working status of the high-frequency / radio frequency generator and the ultrasonic knife generator, and the key drive selection unit includes an ultrasonic mode selection switch, a high-frequency mode selection switch, and a large blood vessel closure selection switch.

[0015] Compared with the prior art, the surgical integrated surgical system for large blood vessel surgery provided by the present invention fully utilizes the characteristics of the ultrasonic scalpel generator and the high-frequency / radiofrequency generator, especially utilizing the existing tool assembly of the ultrasonic scalpel and, under the control of the control module, first starting the high-frequency / radiofrequency generator for coagulation, then the detection control unit controls the ultrasonic scalpel generator to detect the coagulation state value of the large blood vessel, and when the frequency change and impedance change output by the detection control unit are greater than the frequency change threshold and the impedance change threshold, respectively, the high-frequency / radiofrequency generator is turned off, and then the ultrasonic scalpel start-up and closing unit turns on the ultrasonic scalpel generator for ultrasonic cutting. Therefore, the above-mentioned surgical operation can be controlled by only one button to control the working state of the control module, that is, the operation of the entire scalpel, thereby achieving the requirement of labor saving while also accurately judging the state of blood vessel coagulation, avoiding misoperation, and improving the safety of the surgery. In addition, integrating high-frequency / radiofrequency and ultrasound into one ultrasonic scalpel allows the ultrasonic scalpel to be utilized to the greatest extent, while also avoiding the risks brought to the patient by switching the scalpel.

[0022] The following is a further detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0023] like Figures 1 to 4 , which is a schematic diagram of the structure of an integrated surgical system suitable for major vascular surgery provided by the first embodiment of the present invention. The integrated surgical system suitable for major vascular surgery includes a tool assembly 10, a transducer 20 connected to the tool assembly 10, a high-frequency / radiofrequency generator 30 electrically connected to the tool assembly 10, an ultrasonic scalpel generator 50 that drives the tool assembly 10 to produce ultrasonic vibrations, an integrated converter 60 that controls the operating states of the high-frequency / radiofrequency generator 20 and the ultrasonic scalpel generator 50, and a control module 70 that is electrically connected to the integrated converter 60 and is used to control the operating states of the high-frequency / radiofrequency generator 20 and the ultrasonic scalpel generator 50. It is conceivable that the integrated surgical system suitable for major vascular surgery also includes other functional modules, such as a housing assembly, a mechanical assembly that drives the tool assembly, and an electrical connection assembly, etc. These are well known to those skilled in the art and will not be described in detail here.

[0024] The tool assembly 10 includes an outer tube 101, an inner tube 102 inserted into the outer tube 100, a plurality of insulating sealing rings 103 disposed between the outer tube 101 and the inner tube 102, a knife rod 104 inserted into the inner tube 102, at least two insulating spacer rings 105 disposed between the inner tube 102 and the knife rod 104, an insulating sleeve 106 sleeved on the outer side wall of the outer tube 101, and a clamping nozzle 107 rotatably disposed on the inner tube 102. For example, the technical solution disclosed in Patent No. 201921175228.9, entitled "Detachable Ultrasonic Scalpel for Preventing Pin from Disengaging," discloses the outer tube 101, inner tube 102, insulating sealing ring 103, knife rod 104, clamping nozzle 107, and insulating spacer ring 105, etc. Therefore, the above-mentioned parts are all prior art and will not be described in detail here. For details, please refer to the prior art. The insulating sleeve 106 is not disclosed in the prior art and can be made of an insulating material, such as a rubber sheath, a thermoplastic material, or an insulating adhesive coated on the outside of the outer tube 101 by a coating process. The insulating sleeve 106 is used to insulate the outer tube 101 from the outside world to prevent electrical conduction between the outer tube 101 and the outside world, such as muscle.

[0025] The transducer 20 itself is also prior art and is connected to the tool assembly 10. The transducer 20 provides energy to the tool assembly 10, causing the tool shaft 104 to vibrate ultrasonically, thereby achieving the purpose of the surgery. Since the transducer 20 is prior art, it will not be described in detail here.

[0026] The high-frequency / radio frequency generator 30 is used to provide high-frequency power. This is prior art and well-known to those skilled in the art, such as the controller in the technical solution disclosed in Patent No. 201521098679.9, entitled "Radio Frequency Electrosurgical Device." Therefore, the specific circuitry and operating principles of the high-frequency / radio frequency generator 30 will not be described in detail here. The high-frequency / radio frequency generator 30 includes a positive output terminal 31, a negative output terminal 32, and a negative plate 33 electrically connected to the negative output terminal 32. The positive output terminal 31 is electrically connected to the blade rod 104, providing the blade rod 104 with very high-frequency electromagnetic waves, generally above 1.5 MHz. These waves are concentrated in a small area through electrodes. Since cells contain a large number of water molecules (water molecules are polar molecules and are affected by electromagnetic fields), the water molecules oscillate rapidly under the action of this local high-frequency electromagnetic field, achieving the purpose of evaporation, thereby achieving the effect of blood coagulation. Of course, it is conceivable that at higher frequencies, tissue will be damaged, reaching the state of cutting blood vessels. In this embodiment, the frequency provided by the high-frequency / radio frequency generator 30 only causes blood to coagulate. The negative output terminal 32 is electrically connected to the negative plate 33. The negative plate 33 is a conductive metal plate, and its structure and size can be set according to actual needs, which will not be described in detail here. When in use, the negative plate 33 is attached to the human body, and the head of the knife rod 104 can cause the blood in the corresponding blood vessel to coagulate. In addition, the electrical connection method between the positive output terminal 31 and the knife rod 104 is the same as the electrical connection method between the transducer 20 and the knife rod 104, and is also electrically connected to the knife rod 104 by means of an electric ring, which is a prior art, as described in Patent No. 201921175228.9. In addition, the high-frequency / radio frequency generator 30 may also include a high-frequency instrument identification and key input module. The high-frequency device identification and key input module itself is a prior art, which is used to identify the control signal from the integrated converter 60 and transmit it to the high-frequency / radio frequency generator 30 to control its output and shutdown.

[0027] The ultrasonic scalpel generator 50 itself is also prior art and is well known to those skilled in the art, and will not be described in detail here. The ultrasonic scalpel generator 50 is used to provide energy to the transducer 20 to cause the scalpel rod 104 to ultrasonically vibrate, thereby performing muscle cutting. The cutting principle is prior art and will not be described in detail here. In addition, the ultrasonic scalpel generator 50 also includes an ultrasonic scalpel instrument identification and key input module for identifying control signals from the integrated converter 60 and transmitting them to the ultrasonic scalpel generator 50 to control its output and shutdown.

[0028] The integrated converter 60 is electrically connected to the output terminals of the high-frequency / radio frequency generator 30 and the ultrasonic scalpel generator 50 and is used to control the operating states of the high-frequency / radio frequency generator 30 and the ultrasonic scalpel generator 50. Specifically, when the integrated converter 60 switches to the high-frequency / radio frequency generator 30 to activate the high-frequency / radio frequency generator 30, the blade rod 104 and the negative plate 40 form a pair of RF blades. When the integrated converter 60 switches to the ultrasonic scalpel generator 50 to activate the ultrasonic scalpel generator 50, the blade rod 104 forms an ultrasonic scalpel. When the integrated converter 60 controls the high-frequency / radio frequency generator 30 and the ultrasonic scalpel generator 50 to be activated simultaneously, the blade rod 104 can function as both an ultrasonic scalpel and an RF blade. The integrated converter 60 includes a negative plate output unit 61 electrically connected to the negative plate 33, an integrated output unit 62 electrically connected to the cutting tool assembly 10, and a key-driven selection unit 63. The negative plate output unit 61 outputs power to the negative plate 33. Its circuitry is currently available and will not be further described here. The integrated output unit 62 is electrically connected to the high-frequency / radio frequency generator 30 and the ultrasonic scalpel generator 50, converting the received power signal into power suitable for use with either the RF electroscalpel or the ultrasonic scalpel. The key-driven selection unit 63 controls the operating states of the high-frequency / radio frequency generator and the ultrasonic scalpel generator. It is a selection circuit, which is currently available. The key-driven selection unit 63 includes an ultrasonic mode selector switch 631, a high-frequency mode selector switch 632, and a large vessel closure selector switch 633. The ultrasonic mode selector switch 631 is used to select the ultrasonic mode. When the ultrasonic mode selector switch 631 is selected, the ultrasonic scalpel generator 50 is selected and activated directly. The high-frequency mode selector switch 632 is used to select the high-frequency mode. When the high-frequency mode selector switch 632 is selected, the high-frequency / radio frequency selection generator 30 is selected and activated directly. When the ultrasonic mode selector switch 631 or the high-frequency mode selector switch 632 is selected, the ultrasonic scalpel generator 50 or the high-frequency mode selector switch 632 is activated. This is conventional technology and will not be described in detail here. When the large vessel sealing selector switch 633 is selected, surgery on the large vessels is performed. It is contemplated that the integrated converter 60 operates under the control of the control module 70.

[0029] The control module 70 includes a separate ultrasonic scalpel activation unit 71, a separate high-frequency / radiofrequency electroscalpel activation unit 72, and a large vessel sealing activation unit 73. When the ultrasonic mode selection switch 631 is selected, the separate ultrasonic scalpel activation unit 71 only drives the ultrasonic scalpel generator 50 to begin operation. When the separate high-frequency / radiofrequency electroscalpel activation unit 72 is selected, only the high-frequency / radiofrequency generator 30 is activated. When the large vessel sealing selection switch 633 is selected, the large vessel sealing activation unit 73 is activated.

[0030] The large vessel closure initiation unit 73 includes a coagulation threshold setting unit 731, a detection control unit 732, an electrocoagulation on / off unit 733, and an ultrasonic scalpel on / off unit 734. The coagulation threshold setting unit 731 is used to set the coagulation threshold for the large vessel during coagulation. During the coagulation process, the impedance of the large vessel and the frequency of the high-frequency / radiofrequency electroscalpel at the coagulated large vessel change due to water loss. Therefore, by detecting the impedance and frequency changes at the large vessel, it is possible to detect whether the large vessel has completed coagulation. Assuming the initial frequency and impedance are F1 and Z1, respectively, the critical frequency and impedance when coagulation is complete are F2 and Z2, respectively. Coagulation is considered complete when |Z2-Z1|>kzA and |F2-F1|>kfB, where Kz is the tissue impedance coefficient, Kf is the tissue frequency coefficient, and A and B are constants. Therefore, the coagulation thresholds set by the coagulation threshold setting unit 731 are kzA and kfB. The detection control unit 732 is used to control the ultrasonic scalpel generator 50 to detect the coagulation state value of the large blood vessel, that is, to detect the real-time impedance change value and frequency change value. Therefore, the coagulation threshold includes the frequency change threshold and the impedance change threshold.

[0031] When both the impedance change value and the frequency change value reach the coagulation threshold value set by the coagulation threshold setting unit 731, it can be determined that the large blood vessel has completed blood coagulation and the next operation, i.e., the cutting step, can be performed. The electrocoagulation start and close unit 733 is used to control the high-frequency / radio frequency generator 30 to turn on for electrocoagulation when the detection control unit 732 controls the ultrasonic knife generator 50 to turn on, and to turn off the high-frequency / radio frequency generator when the frequency change and impedance change output by the detection control unit 732 are greater than the frequency change threshold and the impedance change threshold, respectively. Therefore, when electrocoagulation is performed on a large blood vessel, the ultrasonic generator 50 and the high-frequency / radio frequency generator 30 work simultaneously, i.e., the ultrasonic generator 50 performs detection and the high-frequency / radio frequency generator 30 performs electrocoagulation.

[0032] The ultrasonic scalpel on / off unit 734 is configured to activate the ultrasonic scalpel generator 50 for ultrasonic cutting when the frequency change and impedance change output by the detection control unit 732 are greater than the frequency change threshold and the impedance change threshold, respectively. Simultaneously, when the frequency change and impedance change output by the detection control unit 732 are greater than the frequency change threshold and the impedance change threshold, respectively, the electrocoagulation on / off unit 733 deactivates the high-frequency / radiofrequency generator 30.

[0033] When assembling the high-frequency / radio frequency generator 30, ultrasonic scalpel generator 50, and integrated converter 60, the high-frequency / radio frequency generator 30, ultrasonic scalpel generator 50, and integrated converter 60 can all be independent components. In this case, the ultrasonic scalpel of the ultrasonic high-frequency surgical integrated system can use existing functional modules without the need for redesign and manufacturing, which helps reduce costs. Figure 5 As shown, it is a circuit formed by connecting existing functional modules and a schematic diagram of the working principle.

[0034] Of course, the high frequency / RF generator 30, ultrasonic knife generator 50, and integrated converter 60 can also be accommodated in a housing cavity, and the integrated converter 60 is a button selection switch set on the housing cavity, so that the cost is integrated as a whole, which is good for appearance and easy to take. Figure 6 As shown, it is a schematic diagram of the circuit and working principle of the high-frequency / radio frequency generator 30, the ultrasonic knife generator 50, and the integrated converter 60.

[0035] Compared with the prior art, the surgical integrated surgical system for large blood vessel surgery provided by the present invention fully utilizes the characteristics of the ultrasonic scalpel generator and the high-frequency / radiofrequency generator, especially utilizing the existing tool assembly of the ultrasonic scalpel and, under the control of the control module, first starting the high-frequency / radiofrequency generator for coagulation, then the detection control unit controls the ultrasonic scalpel generator to detect the coagulation state value of the large blood vessel, and when the frequency change and impedance change output by the detection control unit are greater than the frequency change threshold and the impedance change threshold, respectively, the high-frequency / radiofrequency generator is turned off, and then the ultrasonic scalpel start-up and closing unit turns on the ultrasonic scalpel generator for ultrasonic cutting. Therefore, the above-mentioned surgical operation can be controlled by only one button to control the working state of the control module, that is, the operation of the entire scalpel, thereby achieving the requirement of labor saving while also accurately judging the state of blood vessel coagulation, avoiding misoperation, and improving the safety of the surgery. In addition, integrating high-frequency / radiofrequency and ultrasound into one ultrasonic scalpel allows the ultrasonic scalpel to be utilized to the greatest extent, while also avoiding the risks brought to the patient by switching the scalpel.

[0036] like Figure 6, which is a schematic diagram of the circuit principle provided by the second embodiment of the present invention. The only difference between the first and second embodiments is that the high-frequency / RF generator 30 of the first embodiment utilizes a separate negative electrode plate 33. In the second embodiment, the high-frequency / RF generator 30 directly electrically connects the negative electrode output terminal 32 to the clamping nozzle 107 connected to the inner tube 102, thereby forming a pair of RF cutters with the blade 104 and the clamping nozzle 107. This saves space and is more convenient to use.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention.
