Description

Technical Field

[0001] The present invention relates to the field of surgical instruments, and in particular to an ultrasonic high-frequency instrument input control system. Background Art

[0002] The ultrasonic surgical system uses an ultrasonic frequency generator to drive the handle and the blade to perform ultrasonic vibration at an ultrasonic frequency (55.5kHz) to perform surgical cutting. When cutting, it can break the protein hydrogen bonds in the contacted tissue cells, coagulate the ruptured blood vessels to stop bleeding, and achieve cutting and closure at the same time, so it has strong reliability and high surgical safety. At present, the ultrasonic surgical system is the world's most advanced basic auxiliary instrument for minimally invasive surgery. It is also a routine and essential medical equipment and supplies for large and medium-sized hospitals around the world and China. It is widely used in general surgery, obstetrics and gynecology, and urology. The ultrasonic surgical system generally consists of three parts: a generator, a handle, and a blade. When ultrasonic waves propagate in a certain medium, they will produce mechanical, thermal, acoustic and other responses. The ultrasonic surgical system uses the characteristics of ultrasonic waves to produce mechanical, thermal and cavitation effects on tissues, perform related tissue cutting and closure, and thus achieve clinical applications.

[0003] However, for large blood vessels, their blood pressure is relatively high, their blood vessel walls are relatively thin, and the risk of bleeding is high, making it no longer suitable to use the ultrasonic scalpel to perform blood coagulation while cutting. Therefore, a high-frequency large blood vessel closure device (force ligation bundle) is used. When using this high-frequency large blood vessel closure device (force ligation bundle), first use at least three fingers of one hand to clamp the blood vessel, so that the blood vessel generates impedance under the action of high-frequency electric waves, and the water molecules in the target tissue oscillate and vaporize instantly under the action of high-frequency / radio frequency waves, causing cells to rupture and evaporate, and achieve hemostasis, electrocoagulation and other functions under its constant temperature (40°C). Then use the remaining fingers of the hand to push the blade to cut, thereby completing the coagulation and cutting of the large blood vessels.

[0004] In order to simplify clinical operations and achieve one-step closure of large blood vessels, high-frequency scalpels are now integrated into ultrasonic handpiece scalpels. However, when high-frequency scalpels are integrated into ultrasonic scalpels, the driving lines and control lines used are different, which makes it easy to cause winding during use, and at the same time, it requires major changes to the structure and circuit design of the original transducer system and blade system. Undoubtedly, the winding phenomenon is unacceptable for tense operations, and major changes will lead to reduced compatibility of ultrasonic high-frequency scalpels, higher costs, high manufacturing difficulties, and major changes in clinical usage habits. Summary of the invention

[0005] In view of this, the present invention provides an ultrasonic high-frequency instrument input control system that solves the above-mentioned problem.

[0006] An ultrasonic high-frequency instrument input control system includes a handle assembly, a transducer connected to the handle assembly, a wiring harness assembly arranged on the handle assembly, a wire controller electrically connected to the wiring harness assembly, and a control device electrically connected to the wire controller. The wiring harness assembly includes an ultrasonic wire group connected to the transducer, a high-frequency wire group connected to the knife bar assembly, and an excitation wire group arranged on the handle assembly. The wiring harness assembly passes through the handle assembly and includes a connector. The connector includes a male plug and a female plug. The female plug is arranged on the handle assembly, and the male plug is separated from the handle assembly. The wire controller is electrically connected to the wiring harness assembly and includes a mode selection key and two energy control keys. The control device includes a high-frequency drive module and an ultrasonic drive module. The mode selection key is used to select between the high-frequency drive module and the ultrasonic drive module. When the high-frequency drive module is selected, only the high-frequency wire group provides energy to the handle assembly, and when the ultrasonic drive module is selected, only the ultrasonic wire group provides energy to the transducer.

[0007] Furthermore, the excitation line group includes control lines for controlling the ultrasonic output size and the high-frequency output size.

[0008] Furthermore, the handle assembly includes a handle and a knife rod assembly disposed on the handle, and when the ultrasonic drive module is selected, the transducer drives the knife rod assembly to perform ultrasonic operation.

[0009] Furthermore, one of the two energy control keys is used to increase energy, and the other is used to decrease energy.

[0010] Furthermore, the control device also includes an insertion identification module, a key identification module, and an instrument identification module.

[0011] Furthermore, the insertion identification module is used to determine whether an instrument component is electrically connected to the control device, the button identification module is used to identify which button in the wire controller is pressed, and the instrument identification module is used to identify the state of the electrically connected knife rod component.

[0012] Furthermore, the handle assembly includes a handle and a knife bar assembly arranged on the handle, the handle includes a handshake portion, and the connector is passed through the handshake portion to avoid entanglement during use.

[0013] Furthermore, the female plug of the connector is fixed on the handshake portion and connected to a wiring harness assembly arranged inside the handle, and the male plug is fixed on the wiring harness assembly outside the handle.

[0014] Furthermore, the knife rod assembly includes a knife rod and a sleeve sleeved on the outside of the knife rod, and the high-frequency wire group is electrically connected to the sleeve.

[0015] Compared with the prior art, the ultrasonic high-frequency instrument input control system provided by the present invention can prevent the occurrence of wire entanglement by setting the wiring harness assembly on the handle of the handle assembly instead of on the transducer. At the same time, due to the existence of the wire controller, it can be set near the handle assembly, especially near the user who operates the handle assembly, which can greatly improve the convenience of using the handle assembly, thereby improving work efficiency.

[0020] The specific embodiments of the present invention are further described in detail below. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0021] like Figures 1 to 4 As shown, it is a schematic diagram of the structure of the ultrasonic high-frequency instrument input control system provided by the present invention. The ultrasonic high-frequency instrument input control system includes a handle assembly 10, a transducer 20 connected to the handle assembly 10, a wiring harness assembly 30 arranged in the handle assembly 10, a wire controller 40 electrically connected to the wiring harness assembly 30, and a control device 50 electrically connected to the wire controller 40. It can be imagined that the ultrasonic high-frequency instrument input control system also includes some other functional modules, such as electrical connection components, a control program loaded in the control device 50, and assembly components, etc., which are well known to those skilled in the art and will not be repeated here.

[0022] The handle assembly 10 can be an ultrasonic scalpel, and the ultrasonic scalpel can be modified to have the function of a high-frequency scalpel. The handle assembly 10 includes a handle 11 and a knife bar assembly 12 arranged on the handle 11. The handle 11 and the knife bar assembly 12 themselves are prior art, such as patent number CN201821241462.2, and the patent name is the structure of an ultrasonic scalpel disclosed in an ultrasonic scalpel and an ultrasonic scalpel system. The handle 11 is grasped by the user, so according to ergonomics, the handle 11 includes a handgrip 111, and the wiring harness assembly 30 passes through the handgrip 111 to avoid winding during use. The knife bar assembly 12 includes a knife bar 121, and a sleeve 122 sleeved on the outside of the knife bar 121, which are all prior art.

[0023] The transducer 20 is used to provide ultrasonic energy to the knife bar assembly 12. When the transducer 20 is powered on, it outputs ultrasonic waves and drives the knife bar 121 to output ultrasonic waves for tissue cutting.

[0024] The harness assembly 30 includes an ultrasonic wire group 31 connected to the transducer 20, a high-frequency wire group 32 connected to the shank assembly 12, and an excitation wire group 33 arranged on the handle assembly 10. The ultrasonic wire group 31 is electrically connected to the transducer 20. As is known to all, the transducer 20 has two copper rings for power connection, so the ultrasonic wire group 31 has two wires, which are respectively electrically connected to the two copper rings for power connection to supply power to the transducer 20. The ultrasonic wire group 31 and the high-frequency wire group 32 are integrated together and passed through the handle assembly 10, so that the high-frequency wire group 32 does not need to pass through the transducer 20, so the electrodes of the transducer do not need to be changed, and at the same time, the number of wires in the harness assembly 30 is not limited, and the number of buttons is also not limited, so that the compatibility and expansibility of the entire instrument can be improved.

[0025] The high-frequency line group 32 is electrically connected to the sleeve 122 and the knife rod 121, and provides high-frequency energy to the sleeves 122 and 121. The high-frequency line group 32 has two conductors. When energy is passed through, a high-frequency energy loop is formed, so that the ultrasonic scalpel can be used as a high-frequency scalpel. The sleeve 122 and the knife rod 121 can be switched to achieve monopolar and bipolar energy switching. The excitation line group 33 is a control line for controlling the ultrasonic output size and the high-frequency output size. Specifically, it is used to excite the transducer 20 、The energy output of the sleeve 122 and the knife rod 121 generally has two gear output modes, which is the prior art and will not be repeated here. Of course, the wiring harness assembly 30 also includes some other functional lines, such as signal lines for transmitting signals, etc., which are the prior art and will not be repeated here. The wiring harness assembly 30 finally forms a wiring harness that passes through the handshake portion 111 of the handle 11, preferably, passes through the end of the handle of the handshake portion 111, so that when the doctor uses it, it will not cause winding, because during use, the wiring harness assembly 30 is always freely hanging down, and it will not be like the instrument disclosed in patent number CN201821241462.2, and the patent name is ultrasonic scalpel and ultrasonic scalpel system. In the ultrasonic scalpel disclosed in patent number CN201821241462.2, the wiring harness is connected to the tail of the transducer, and it will be wound as the transducer rotates during use, which will undoubtedly affect the normal use of the doctor.

[0026] In order to facilitate wiring, the wiring harness assembly 30 further includes a connector 34, and the connector 34 includes a male plug 341 and a female plug 342. The female plug 341 is arranged on the handle assembly 10. Specifically, the female plug 341 is fixed on the handshake portion 111 and connected to the wiring harness assembly 30 arranged inside the handle 11. The male plug 342 is separated from the handle assembly 10 and fixedly connected to the wiring harness assembly 30 outside the handle 11. The wiring harness assembly 30 outside the handle 11 can be separated from the entire handle assembly 10 by the connector 34, so that the wiring harness assembly 30 outside the handle 11 can be reused, while the handle assembly 10 is still disposable, which can further reduce the medical burden of the patient.

[0027] The wire controller 40 is electrically connected between the wiring harness assembly 30 and the control device 40, and is arranged on the wiring harness assembly 30 outside the handle 11, and includes a mode selection key 41, and two energy control keys 42. The mode selection key 41 is used to put the blade rod assembly 12 and the transducer 20 of the handle assembly 10 in different working states according to the user's selection. The energy control key 42 is used to adjust the energy output by the blade rod assembly 12 and the transducer 20 of the handle assembly 10. It can be imagined that one of the two energy control keys 42 is used to increase energy and the other is used to reduce energy. The working principle of the mode selection key 41 and the energy control key 42 itself should be the prior art, that is, each time it is pressed, it triggers a signal to the control device, so its specific structure and working principle are not repeated here. The wire controller 40 can be set on the wire harness assembly 30 close to one side of the handle assembly 10 but outside the handle 11. During use, the doctor can operate the wire controller 40 at close range, such as operating the instrument assembly 10 with the right hand and operating the wire controller with the left hand, so as to conveniently select the working state of the handle assembly 10 and the transducer 20. In this way, there is no need to ask other people to cooperate with the doctor's needs, which improves the doctor's work efficiency. Therefore, by adding the wire controller 40, the setting button of the ultrasonic blade head can be placed on the wire controller 40, and only the excitation button is set on the handle assembly 10, so as to realize the separation of excitation and setting. This will not change the doctor's usage habits, thereby further reducing the head cost of the handle assembly 10, and at the same time allowing the doctor to easily adjust the function and energy settings.

[0028] The working principle and control program of the control device 50 are prior art, and include a high-frequency driving module 51, an ultrasonic driving module 52, an insertion identification module 53, a button identification module 54, and an instrument identification module 55. The high-frequency driving module 51 is used to drive the handle assembly 10 to be used as a high-frequency scalpel, so when the mode selection key 41 selects the high-frequency driving module 51, the handle assembly 10 is a high-frequency scalpel. When the ultrasonic driving module 52 is selected, the handle assembly 10 is an ultrasonic scalpel, and the transducer 20 can drive the knife bar assembly 12 to perform ultrasonic work. The insertion identification module 53 is used to determine whether there is a handle assembly 10 or a transducer 20 electrically connected to the control device 60. The button identification module 64 is used to identify which button in the wire controller 40 is pressed. The instrument identification module 65 is used to identify the state of the electrically connected knife bar assembly 12, such as life parameters, specifications, etc. The insertion recognition module 53, the key recognition module 54, and the device recognition module 55 are existing technologies and will not be described in detail here.

[0029] Compared with the prior art, the ultrasonic high-frequency instrument input control system provided by the present invention can prevent the occurrence of wire entanglement by setting the wiring harness assembly 30 on the handle 11 of the handle assembly 10 instead of on the transducer 20. At the same time, due to the existence of the wire controller 40, it can be set near the handle assembly 10, especially near the user who controls the handle assembly 10, which can greatly improve the ease of use of the handle assembly 10, thereby improving work efficiency.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention is included in the scope of the claims of the present invention.
