Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of surgical instruments, and more particularly, to a surgical instrument suitable for a super-electric hybrid energy platform. BACKGROUND

[0002] An ultrasonic knife used in surgical procedures is a kind of surgical instrument based on ultrasonic waves, which converts ultrasonic signals into mechanical vibrations through an ultrasonic transducer, and is often used for cutting tissue. A high-frequency electrotome (referred to as an electrotome) is also a commonly used surgical instrument, which is often used for sealing blood vessels and requires high-frequency electric energy to drive. An ultrasonic electrotome (referred to as an ultrasonic electrotome) has the advantages of both ultrasonic knives and electrotomes, which helps to improve the surgical effect.

[0003] In order to obtain a better surgical effect when applying an ultrasonic electrotome, a super-electric hybrid energy platform can be built. In this platform, the instruments used to perform surgical operations, energy transmission lines, transducers related to energy conversion, electrical connection devices, and energy source equipment, etc. all need to be specially designed to ensure the safety and stability of the system during operation.

[0004] The ultrasonic energy conversion device suitable for the super-electric hybrid energy platform, also known as the ultrasonic transducer (hereinafter referred to as the transducer), not only converts the ultrasonic energy (such as ultrasonic current with a frequency of 55 kHz) that drives the ultrasonic knife function into mechanical vibration and transmits it to the knife head at the front end of the surgical instrument, but also serves as an electrical channel between the surgical instrument and the energy source equipment. It also needs to transmit high-frequency energy (such as high-frequency current with a frequency of 470 kHz) to the jaw at the front end of the surgical instrument, as well as some signals generated at the instrument end for control or detection back to the equipment end and other functions.

[0005] The general structure of the surgical instrument described in the present disclosure includes a handle for holding and an operating part for performing surgery. The main components of the operating part include a knife shaft, an inner sleeve, and an outer sleeve. The distal end of the operating part is the execution end, which includes a knife head and a jaw. When it is necessary to use super-electric hybrid energy to perform surgical operations, high-frequency current needs to be transmitted to the execution end, and the transmission path of the energy needs to be specially designed to achieve it. Among them, the handle of the surgical instrument not only provides the operator with convenient operation, but also connects with the transducer and transmits energy or signals, so the design of its structure is one of the important links to realize the use of super-electric hybrid energy of surgical instruments.

Also, portions irrelevant to the description of the exemplary embodiments are omitted in the accompanying drawings for the sake of clarity.

[0041] In the present disclosure, it should be understood that terms such as "include" or "have" are intended to indicate that there are features, numbers, steps, actions, components, parts or combinations thereof disclosed in the specification, and do not exclude the possibility that one or more other features, numbers, steps, actions, components, parts or combinations thereof exist or are added.

[0042] It is also necessary to note that the embodiments in the present disclosure and the features in the embodiments can be combined with each other without conflict. The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0043] In the scenario of applying super-electric hybrid energy in surgical operation, the blade head and the jaw of the surgical instrument are used to perform surgical operation by super-electric hybrid energy. For example, in one mode, after clamping the tissue between the blade head and the jaw, two poles of high-frequency current are formed to realize the function of electric knife, and in another mode, the blade head only performs the function of ultrasonic knife. In addition, the surgical instrument also needs to facilitate the operator to select the working mode or to check the working state. Based on this requirement, the specific embodiments of the surgical instrument proposed in the present disclosure are as follows.

[0044] The surgical instrument suitable for the super-electric hybrid energy platform provided by the present disclosure is shown in Figure 1 . Figure 1 The schematic diagram showing that the surgical instrument 1 is connected with the transducer 2 for use is shown.

[0045] Figure 1 The surgical instrument 1 comprises a handle body 11, a first electrode 12, a second electrode 13, and an operating part 14, a signal circuit board 15 and a third electrode 16.

[0046] The first electrode 12 is arranged inside the handle body 11, near the position where the transducer is connected (shown by the dashed line in the figure), for connecting with one electrode of the high-frequency current circuit in the connected transducer 2.

[0047] The second electrode 12 is arranged inside the handle body 11, near the position of the operating part 14 (shown by the dashed line in the figure), and is electrically connected with the first electrode 12.

[0048] The operating part 14 is fixedly installed at one end of the handle body 11, away from the transducer. The operating part 14 comprises an outer sleeve 141 and a waveguide rod 142 inside the outer sleeve 141. The distal end of the outer sleeve 141 is connected with a clamp arm 143, and the proximal end is connected with the second electrode 13. The distal end of the waveguide rod 142 is a blade head 1421, and the proximal end is inside the handle body 11, for connecting with the other electrode of the high-frequency current circuit in the connected transducer 2. The outer sleeve 141 and the waveguide rod 142 are both conductive bodies and are insulated from each other, so that two electrodes of the high-frequency current can be formed at the clamp opening formed by the blade head 1421 and the clamp arm 143. In some embodiments, the operating part 14 further comprises a knob 144 arranged at the proximal end of the outer sleeve 141 and the waveguide rod 142, and connected with the handle body 11, through which the waveguide rod 142 can be rotated to be screw-connected with the conducting rod of the connected transducer.

[0049] When the surgical instrument 1 with the above structure is connected with the transducer 2, the high-frequency current is transmitted to the clamp arm 143 and the blade head 1421 through the outer sleeve 141 and the waveguide rod 142, and at the same time the waveguide rod 142 can also obtain ultrasonic vibration from the connected transducer 2, to drive the blade head 1421 to realize the ultrasonic knife function, and realize the bipolar electrotome function at the clamp opening formed by the blade head 1421 and the clamp arm 143, so that the surgical operation can be performed by using the super-electric hybrid energy at the end, which is beneficial to improve the surgical effect.

[0050] The signal circuit board 15 is arranged inside the handle body 11, and the third electrode 16 is arranged inside the handle body 11 close to the transducer 2. The signal circuit board 15 is electrically connected with the first electrode 12 and the third electrode 16 respectively. When the surgical instrument 1 is connected with the transducer 2, the first electrode 12 is connected with one electrode of the high-frequency current circuit in the transducer 2, and also connected with one electrode of the signal current circuit. The connection mode of the high-frequency current circuit and the signal current circuit sharing one electrode can reduce one electrode in the handle, simplify the structure of the handle, and also reduce the risk caused by poor electrode contact. Since the high-frequency current is usually a high-voltage (for example, 220V) differential signal, and the signal current is usually a low-voltage (for example, 12V) level signal, the current transmission of the two different signals shares one electrode, and the crosstalk between them is within an acceptable range, so the safety and stability of the system can be ensured.

[0051] The signal circuit board 15 is an integrated circuit board without power supply, and the required power supply current is obtained through the first electrode 12 and the third electrode 16. Unlike the structure of the existing surgical instrument using a switching circuit board requiring three electrodes, the signal circuit board in the embodiment of the present disclosure only needs to be connected with two electrodes to obtain the power supply current. At the same time, the signal current circuit not only has a power supply function, but also has a transmission function, and the communication signal between the signal circuit board 15 and the device end is also transmitted through the signal current circuit.

[0052] Further, the surgical instrument according to the embodiment of the present disclosure further comprises an input assembly 17 arranged on the handle body 11. The signal circuit board 15 can receive the input instruction of the input assembly 17 to generate a first signal, and the first signal is transmitted to the device end through the connected transducer 2.

[0053] The input assembly 17 can be a press key switch and / or a slide key switch, and is in contact connection with the signal circuit board 15. For example, Figure 1In some embodiments, the input component 17 includes two finger button switches, which are convenient for the operator to press with fingers when holding the handle, and a slide button switch, which can have multiple gears and can be selected by sliding the slide button. In order to adapt to the operation habits of the operator, the slide button switch can be two groups, which are respectively arranged on the two sides of the handle. The input component 17 can also be a touch screen, which is electrically connected with the signal circuit board 15. The input component 17 can also be a wireless remote controller, which is wirelessly connected with the signal circuit board 15. The input instructions of the input component 17 can be set according to requirements. For example, the two finger button switches can be used to select the energy gears, and the slide button switch can be used to select more detailed energy modes, such as outputting ultrasonic energy first and then outputting electric energy in one energy mode, outputting ultrasonic-electric hybrid energy first and then outputting electric energy in another energy mode, and so on. The signal circuit board receives the input instructions of the input component to generate a first signal, and the first signal is sent to the device end through the signal current line. The device end can output ultrasonic-electric hybrid energy based on the first signal.

[0054] Further, according to the surgical instrument of the embodiments of the present disclosure, the signal circuit board 15 can also generate a second signal based on the detection of the working state of the operating part 14. For example, by detecting the impedance value after the knife head 1421 and the jaw 143 are closed to determine whether abnormal wear occurs at the jaw 143, corresponding prompt information is sent. The second signal generated by the signal circuit board 15 can also be transmitted to the device end, which is processed by the device end to prompt the operator, or is used to detect the number of uses of consumables and other aspects of performance improvement, which is not limited by the present disclosure.

[0055] The surgical instrument 1 can also include a prompt component arranged on the handle main body 11. The signal circuit board 15 can send corresponding prompt information to the prompt component according to the detection of the working state of the operating part 14. For example, when the prompt component is an LED indicator, the corresponding prompt information is to light up the indicator of different colors to indicate to the operator whether the working state of the operating part 14 is normal, which is convenient for the operator to detect faults. The prompt component can also be an audio indication component, which can prompt the operator through different warning sounds, or an audio + light combined indication component.

[0056] Figure 2 The structure in the handle main body of the surgical instrument of the embodiments of the present disclosure is shown in the schematic view.

[0057] Figure 2In the embodiment, the first electrode 12 and the third electrode 16 are both ring-shaped contact electrodes, and are fixed in the same electrode plate, which is shaped and positioned to match the connected transducer 2. The electrode plate has a through hole in the center to facilitate the passage of the conducting rod 21 of the transducer 2 to connect with the proximal end of the waveguide rod 142. The second electrode 13 is a ring-shaped electrode on the front of the handle main body, to connect the outer sleeve 141 to the high-frequency current circuit. The signal circuit board 15 is positioned inside the handle main body 11 near the input assembly, and the two electrodes of the signal circuit board 15 are connected to the first electrode 12 and the third electrode 13, respectively.

[0058] Figure 3 FIG. 4 is a schematic diagram of the structure of the transducer 2 connected to the surgical instrument 1 according to the embodiment of the present disclosure.

[0059] Figure 3 In the embodiment, the front end of the transducer 2 is a conducting rod 21, which is used to connect with the waveguide rod 142 in the surgical instrument 1 to transmit ultrasonic vibrations, and to transmit one electrode of the high-frequency current circuit to the blade head 1421 through the waveguide rod 142. The front end of the housing 22 of the transducer 2 also has two electrodes, one of which is a common electrode 23 for the signal current circuit and the high-frequency current circuit, and the other is a signal electrode 24, which is the other electrode of the signal current circuit.

[0060] For clarity, the connection relationship between the surgical instrument 1 and the transducer 2 according to the embodiment of the present disclosure is schematically shown in Figure 4

[0061] Figure 4 In the embodiment, the ultrasonic vibrations generated by the transducer 2 are transmitted to the waveguide rod 142 through the conducting rod 21. One electrode of the high-frequency current circuit is transmitted to the outer sleeve 142 through the transducer common electrode 23, via the first electrode 12 and the second electrode 13, and the other electrode is directly transmitted via the waveguide rod 142. One electrode of the signal current circuit is transmitted to the first electrode 12 of the surgical instrument 1 via the common electrode 23 of the transducer 2, to connect the signal circuit board 15, and the other electrode is transmitted to the third electrode 16 of the surgical instrument 1 via the signal electrode 24 of the transducer 2, to connect the signal circuit board 15. Through the above structure, ultrasonic hybrid energy can be used in surgical operations. At the same time, by using the common electrode, the signal circuit board 15 built-in the handle main body not only can obtain power supply, but also can transmit the signals generated thereby to the device end via the signal current circuit in the transducer 2, to realize the functions of control, optimization, etc. of the surgical process, and to help improve the surgical effect.
