Technical Field

The present disclosure relates to the field of medical transducers, and more particularly, to a transducer core fixation assembly suitable for use in a super-electric hybrid energy platform.

Background

High frequency scalpels (scalpels for short) are also a common surgical instrument commonly used for sealing blood vessels and require high frequency electrical energy to drive. The ultrasonic electrotome (for short, the ultrasonic electrotome) has the advantages of the ultrasonic electrotome and the electrotome, and is beneficial to improving the operation effect.

On the other hand, in order to reduce the improvement cost and ensure stable ultrasonic performance, the change of the core structure is also reduced.

In this case, a transducer suitable for use in a super-electric hybrid energy platform requires redesigning the fixed components of the transducer core to address the above-described issues.

For the scenario of surgical application of super-electric hybrid energy, the transducer and inner core fixing assembly structure suitable for the super-electric hybrid energy platform provided by the embodiment of the disclosure is shown in fig. 1-3.

First, the structure of the inner core and the internal structure of the outer shell proposed by the technical solution of the embodiment of the present disclosure will be described with reference to fig. 1. For clarity, other components in the transducer proposed by embodiments of the present disclosure are not shown in fig. 1.

In fig. 1, one end of the inner core 01 is provided with a conductive rod 011, the middle part is provided with a flange 012, and the other end is provided with an ultrasonic generator 013. Two ultrasonic electrodes 0131 are provided on the ultrasonic generator 013 for connecting an ultrasonic current line, thereby obtaining ultrasonic energy to drive the ultrasonic generator 013. The inner core 01 is of a general structure.

According to the embodiment of the disclosure, the casing 02 is cylindrical, a space for accommodating the inner core of the transducer is formed inside the casing 02, an annular inner wall flange 021 is arranged in the middle of the casing 02, and an axial limiting protrusion 022 is further arranged on the inner wall. The conductive rod 011 of the assembled core 01 will pass out of one end of the outer shell 02. In addition, in some embodiments, the transducer further includes a cable connection 08, secured to the other end of the housing 02. The following detailed description will be given with reference to the accompanying drawings.

In the following embodiments, unless otherwise specified, the direction in which the conductive rod 011 of the core 01 is pointed is referred to as "front".

Fig. 2 is a schematic view showing the internal structure of the assembled transducer, and fig. 3 is a schematic view showing the components of the transducer in fig. 2 separated.

The transducer in fig. 2 comprises: the elastic sleeve 03 comprises an inner core 01, an outer shell 02, an elastic sleeve 03, a first fixing piece 04 and a second fixing piece 05.

The front part of the inner core 01 is a conducting rod 011, the middle part is provided with a circumferential flange 012, the tail part is an ultrasonic generator 013, and the inner core 01 is an electric conductor and is used for connecting one electrode of a high-frequency current circuit.

The outer shell 02 has a cylindrical structure, and an annular inner wall flange 021 is arranged in the middle of the inner wall. The arrangement of the inner wall flange 021 can be better understood in conjunction with fig. 1. The case 02 is an electric conductor for connecting the other electrode of the high-frequency current line.

The elastic sleeve 03 wraps the flange 012, one end of the elastic sleeve 03 is provided with a clamping notch 031, and the outer edge of the elastic sleeve 03 is contacted with the inner wall of the shell 02. In some embodiments, one end of the flange 012 is provided with a plurality of notches, and a plurality of snap notches provided on the elastic sleeve 03 may be provided correspondingly.

The first fixing member 04 is provided at an end of the flange 012 remote from the conductive rod 011. One end of the first fixing piece 04 is provided with a clamping protrusion 041 for clamping with a clamping notch 031 at one end of the elastic sleeve 03. The other end of the first fixing piece 04 abuts against the inner wall flange 021, that is, the first fixing piece 04 is supported by the inner wall flange 021 as the bottom and fixed in the middle of the inner shell 02. The outer surface of the first fixing member 04 is in contact with the inner wall of the outer shell 02, and the inner surface is not in contact with the inner core 01.

The second fixing member 05 is provided at an end of the flange 012 near the conductive rod 011 and is fixedly connected to the outer case 02 so that the inner core 01 is fixed in the outer case 02. The center of the second fixing member 05 is provided with a through hole for the conductive rod 011 to pass through. The second fixing element 05 and the casing 02 may be connected by screwing, clamping, welding, riveting, etc., and a simple and stable manner is screwing.

By wrapping the flange 012 with the elastic sleeve 03, direct contact between the inner core 01 and the outer shell 02 is isolated, and insulation between the two electrodes can be achieved when the inner core 01 and the outer shell 02 are connected with a high-frequency current line. The elastic sleeve 03 can absorb part of noise caused by friction or impact of the inner core 01 to the outer shell 02 during vibration, so that the effects of buffering and noise reduction are achieved.

On the basis of the elastic sleeve 03, the inner core 01 is fixed in the outer shell 02 by the first fixing piece 04 and the second fixing piece 05 on the two sides of the flange 012, so that the front-back movement of the inner core 01 during operation is limited not to exceed the safety range. The first fixing piece 04 and the inner core 01 adopt a non-contact structure, so that the first fixing piece 04 is conveniently sleeved on the inner core 01 during assembly, and meanwhile, the creepage distance between the inner core 01 and the two electrodes of the outer shell 02 is increased, so that better insulating performance is obtained.

Further, according to the embodiment of the present disclosure, the inner wall of the housing 02 is further provided with an axial limit protrusion 022, and fig. 1 may be combined to more clearly understand the arrangement manner of the limit protrusion 022. And the outer surface of the first fixing piece 04 is provided with a limiting groove 042 corresponding to the limiting protrusion 022, so that the axial fixing between the first fixing piece 04 and the inner wall of the shell 02 can be realized. To enhance fixation, such a limit setting may also be provided in multiple sets.

The above-mentioned clamping and fixing of the first fixing member 04 and the flange 012, and the axial fixing between the first fixing member 04 and the housing 02 mainly have the following effects: when the transducer is connected to the surgical instrument, the cutter bar of the surgical instrument is fixed to the conductive rod 011 of the inner core 01, usually by screwing, and when the cutter bar is rotated to connect the transducer, the above structure can play a role of limiting the rotation of the inner core 01, so that the cutter bar can be mounted on the conductive rod 011.

Further, according to embodiments of the present disclosure, the second fixture 05 may be a split structure composed of two or more components. For example, as shown in fig. 3, the second fixing member 05 includes a metal ring 051 and a monopolar electrode disc 052. The metal ring 051 and the monopole electrode plate 052 are sleeved and fixed at the front end of the flange 012, and the monopole electrode plate 052 is connected with a signal wire extending to the tail part of the inner core. In addition, in the sleeving structure of the metal ring 051 and the monopolar electrode disc 052, an O-shaped sealing ring 053 can be arranged at the joint to achieve a better sealing effect. As shown in fig. 3, 2O-rings 053 were employed. The second fixing element 05 may also be a component of one-piece construction, for example, the second fixing element 05 is a bipolar electrode disk, one of the electrodes of which is connected to the signal conductor and the other electrode is connected to the housing 02.

The second fixing element 05 has the function of an electrode, and in the case that the second fixing element 05 is in a split structure as shown in fig. 3, the metal ring 051 is connected with the shell 02 to form one electrode of a high-frequency current circuit, the monopole electrode disc 052 is insulated from the inner core 01 and the shell 02, the electrode is connected with a signal wire, and the signal wire is used for being connected with a signal circuit in a surgical instrument to realize transmission of various signals. When the transducer is connected to the surgical instrument, high frequency current may be conducted from the transducer to the actuating end of the surgical instrument through the eyelet 051 and the conductive bar 011 to perform the function of a high frequency electric knife. Therefore, the metal ring 051 can be made of copper with good conductivity and screwed to the front end of the housing 02, thereby forming the same high-frequency current electrode as the housing 02.

Further, according to an embodiment of the present disclosure, a wire routing groove 043 is further provided at the outer surface of the first fixing member 04. The wire wiring groove 043 can limit the signal wire in the wiring groove, avoids the direct contact of the wire and the inner core 01, and reduces the risks of aging, damage or short circuit and the like of the wire due to the influence of factors such as heating of the inner core.

According to the embodiment of the disclosure, the first fixing member 04 is made of a high-temperature resistant insulating material, for example, a Polyetheretherketone (PEEK) material, which is a high-molecular steel material with good physical and mechanical properties. The elastic sleeve and the elastic gasket are made of high-temperature resistant elastic materials, such as fluororubber, silica gel and the like, and fluororubber has good high-temperature resistance of 200 ℃ and can be preferable. The insulating portion in the second fixing member 05 may be made of the same material as the first fixing member 04. The selection of these materials can be adapted to the high temperature sterilization environment of the transducer during use without affecting the performance of the transducer.

According to an embodiment of the present disclosure, the transducer further includes an elastic pad 06 covering the front end surface of the flange 012 and being pressed and fixed by the second fixing member 05. After the elastic gasket 06 is arranged, the sealing effect on the inner core can be further obtained, and the water vapor is prevented from entering the outer shell 02 to influence the ultrasonic generator 013 of the inner core 01. For example, when the transducer is sterilized by using plasma, ethylene oxide, liquid immersion or under high temperature and high pressure environment, the phenomenon that the transducer cannot work normally due to water inlet or moisture in the transducer can be avoided. On the other hand, the elastic gasket can further absorb vibration noise and plays a role in buffering and noise reduction.

There are various structures for wrapping the elastic sleeve 03 around the flange 012 according to the embodiments of the present disclosure, for example, two structures for wrapping the elastic sleeve 03 around the flange 012 as shown in fig. 4 and 5. The elastic sleeve 03 in fig. 4 wraps the front and rear end surfaces of the flange 012. The elastic sleeve 03' in fig. 5 only wraps the rear end face and the outer edge of the flange 012. The wrapping structure of fig. 4 has a larger creepage distance between the inner core 01 and the outer shell 02 and higher reliability, but the wrapping structure of fig. 5 is simpler to assemble. In addition, there is a third wrapping structure, which is slightly adjusted on the wrapping structure in fig. 4, so that the area of the front end of the flange 012 is reduced, only a part of the edge is wrapped, the creepage distance between the two electrodes of the inner core 01 and the outer shell 02 is ensured to be enough, and then the elastic gasket 06 is matched at the moment, so that a good sealing effect can be obtained.

In the above-mentioned wrapping structure of the elastic sleeve 03 on the flange 012, the elastic sleeve 03 needs to be insulated from the housing 02, so that the thickness of the wrapped flange 012 needs to meet the insulation requirement, but the thickness of the outer edge of the elastic sleeve 03 should not be too large, otherwise, the inner core 01 is inclined due to uneven edge extrusion during assembly, and the vibration effect is affected. Thus, the thickness of the elastic sleeve 03 may be set to: the thickness of the package at the outer fringe of ring flange 012 (i.e. between ring flange 012 outer fringe and the inner wall of shell 02) is between 1mm ~ 4mm, for example 2mm, and the thickness of the package at ring flange 012 front and back terminal surface sets up according to the demand, because the part of package at ring flange 012 rear end face needs to be in joint with first mounting 04, can slightly thick, for example 3mm, and the whole rear end face of package ring flange 012, and the part of package at preceding terminal surface can slightly thin, for example 1mm, and the area of package can slightly be little, for example only wrap up a part of preceding terminal surface border, and such structure not only fastening effect is good also is convenient for the assembly. Similarly, the thickness of the elastic pad 06 is also ensured that the elastic compression amount thereof can support the axial vibration generated by the inner core 01, so that the transducer works normally, for example, the thickness of the elastic pad 06 can be 3mm.

Further, one end of the inner core 01 is provided with a conductive rod 011, and the other end is provided with an ultrasonic generator 013, and the transducer of the disclosed embodiment further includes a third fixing member 07, which is disposed between the ultrasonic generator 013 of the inner core 01 and the inner wall of the outer casing 02. The third fixing piece 07 is sleeved outside the ultrasonic generator 013 and is not contacted with the ultrasonic generator 013, a wire hole 071 and a coil holder 072 for fixing wires are arranged at the bottom of the tail inner sleeve piece 07, so that the wires in the transducer can conveniently pass through and be wound and fixed, and the probability of contact with the inner core 01 due to movement or looseness of the wires is reduced. In some embodiments, the wires inside the transducer include signal wires connecting the front electrode pads, ultrasonic wires soldered to the two ultrasonic electrodes 0131 of the ultrasonic generator. For example, the signal wire is routed in the inner housing 02 along the wire routing groove 042 on the outer surface of the first fixing member and then is threaded out from the wire hole 071 of the third fixing member 07, so that the effect of isolating and routing the signal wire can be achieved, and the signal wire is prevented from contacting the inner core or the outer housing. At the same time, an ultrasonic wire welded to the ultrasonic electrode 0131 on the ultrasonic generator is also passed through the wire hole 071, and the ultrasonic wire is used for connecting the two electrodes of the ultrasonic current line, so that the ultrasonic current drives the ultrasonic generator 013 to generate mechanical vibration.

The third fixing member 07 is also made of an insulating material, and the same material as that of the first fixing member 04 can be used. The third fixing piece 07 not only plays a role of conducting wire routing, but also insulates and isolates the ultrasonic generator, so that the electrode of the ultrasonic generator is prevented from being contacted with the shell, the high-voltage breakdown phenomenon caused by too close distance between the electrode and the shell is avoided, and the stability of equipment is improved.

Further, a transducer according to an embodiment of the present disclosure further comprises a cable connection 08. The cable connector 08 is fixedly connected to the housing 02 and is provided with a cable hole 081 for the passage of a transmission cable. The transmission cable is connected with energy source equipment in the super-electric hybrid energy platform, so that high-frequency current, ultrasonic current and signal current transmission are realized. The cable connection 08 may be made of the same metal as the case 02, and may be directly connected to one electrode of the high-frequency current line in the transmission cable, thereby changing the case 02 into one electrode of the high-frequency current line. The cable connector 08 and the housing 02 can be screwed, sleeved or welded.

When the transducer of the present disclosure is used to connect with a surgical instrument, high frequency current is supplied to the jaw at the front end of the surgical instrument through the inner core 01 and the outer shell 02, and when the jaw clamps tissue, a loop of high frequency current is formed at the jaw due to the conductivity of the tissue, thereby realizing the function of a high frequency electric knife. It will be appreciated that ultrasound energy and high frequency energy may be mixed or alternatively delivered to a surgical instrument using the transducers of the present disclosure in the context of the application of super-electric mixed energy, as desired for a surgical procedure. On the other hand, the transducer can also be connected with a common ultrasonic knife, and only the function of the ultrasonic knife is realized. Therefore, the transducer has more universal application scenes.

Fig. 6 shows an external structural schematic of a resulting transducer according to an embodiment of the present disclosure. After the inner core 01, the outer shell 02 and the cable connecting piece 08 are assembled fixedly, the front part of the transducer only exposes a conducting rod 011 of the inner core 01 and is used for being connected and fixed with a waveguide rod of a surgical instrument to transmit ultrasonic vibration, a metal ring 051 of the front end fixing piece 05 is used as one electrode of a high-frequency current line to be matched with the conducting rod 011 to transmit the high-frequency current to a jaw of the surgical instrument, and a monopolar electrode disc 052 of the front end fixing piece 05 is used for being connected with a signal current line in the surgical instrument. The cable connection 08 at the tail of the transducer is connected with a transmission cable to realize the electrical connection between the transducer and the super-electric hybrid energy source device.

The following briefly describes a method of assembling a transducer using a fixture assembly of embodiments of the present disclosure: the elastic sleeve 03 and the first fixing piece 04 are sequentially sleeved on the inner core 01, the inner core 01 is placed in the outer shell 02, the first fixing piece 04 stands on the inner wall flange 021, the elastic gasket 06, the monopole electrode disc 052, the metal ring 051 and an O-shaped sealing ring required by a connecting position are placed in the inner core, and after the metal ring 051 is screwed and fixed with the outer shell 02, the inner core 01 is also fixed in the outer shell 02. Further, the third fixing member 07 is sleeved at the tail of the inner core 01, the wires inside the transducer are wound and fixed on the coil rack 072 after being penetrated out from the wire holes 071 and connected with the corresponding wires in the cable, and finally the cable connecting member 08 is connected and fixed with the outer shell 02 to complete the assembly.
