Description

Technical Field

[0001] This application relates to the field of surgical instruments, and in particular to an integrated ultrasonic scalpel and ultrasonic scalpel system. Background Technology

[0002] An integrated ultrasonic scalpel integrates the transducer into the handle housing of a handheld device, forming a non-detachable integral connection. Because the transducer is integrated into the handle housing, and the transducer needs to rotate circumferentially with the shaft assembly, the conductive connection between the transducer and the power cable must not impede the transducer's axial rotation, and must avoid cable entanglement caused by the transducer's circumferential rotation. Summary of the Invention

[0003] This invention proposes an integrated ultrasonic scalpel and ultrasonic scalpel system to solve the problems of electrical connection structure and anti-entanglement between transducer and power supply cable.

[0004] In a first aspect, this application proposes an integrated ultrasonic scalpel, which includes a transducer housed within a housing, a trigger assembly partially housed within the housing, a shaft assembly rotatably connected to the housing, an excitation assembly connected to the housing, a cable, and a conductive socket, wherein the cable is electrically connected to the conductive socket; the transducer includes...

[0005] The transducer housing is rotatably connected to the casing.

[0006] The transducer core is connected to one end of the transducer housing via a buffer and is used to connect to the waveguide to transmit ultrasonic vibrations to the waveguide.

[0007] Stacked units, which are fixedly connected to the transducer core, are used to convert electrical energy into ultrasonic vibration;

[0008] The conductive plug is electrically connected to the stacking unit and is attached to the other end of the transducer housing. The conductive plug is used to rotatably connect to the conductive socket to transfer electrical energy to the stacking unit.

[0009] In another embodiment, the transducer housing includes an upper shell, a middle shell, and a lower shell. The upper shell and the lower shell are respectively connected to both ends of the middle shell to form a receiving cavity. A portion of the transducer core and the stacking unit are disposed in the receiving cavity, and the conductive plug is plugged into the lower shell.

[0010] In another embodiment, the circumferential sidewalls of the middle shell are provided with heat dissipation holes.

[0011] In another embodiment, the lower housing includes at least one wire through hole for a conductor to pass through between the conductive plug and the stacking unit.

[0012] In another embodiment, the end face of the lower shell away from the middle shell is provided with a plug slot and a plurality of wire-locking parts arranged around the plug slot. The conductive plug is inserted into the plug slot, and the plurality of wire-locking parts are used to fix the wires.

[0013] In another embodiment, the lower shell has multiple dividing grooves along its circumferential sidewalls, so that the sidewalls of the lower shell form multiple cantilevered engagement portions.

[0014] In another embodiment, the lower housing includes contact electrodes that are electrically connected to the stacking unit. When the conductive plug is plugged into the lower housing, the contact electrodes are electrically connected to the conductive plug.

[0015] In another embodiment, the transducer housing is made of plastic.

[0016] In another embodiment, the buffer includes a first buffer and a second buffer, the first buffer being used to support the transducer housing in a first direction along the transducer axis, and the second buffer being used to support the transducer housing in at least a second direction along the transducer axis, wherein the first direction and the second direction are opposite.

[0017] Secondly, this application proposes an ultrasonic scalpel system, which includes an ultrasonic host and an integrated ultrasonic scalpel as described in any of the above claims. The host is electrically connected to the integrated ultrasonic scalpel and is used to provide power to the integrated ultrasonic scalpel.

[0018] The aforementioned integrated ultrasonic scalpel achieves a rotatable plug-in electrical connection by setting a transducer housing and a conductive plug set in the transducer housing and a conductive socket set in the housing for electrical connection with the cable. This decouples the rotation of the transducer from the cable, avoids cable tangling, and ensures the electrical connection between the cable and the transducer. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0038] In this specification, references to "one embodiment," "some embodiments," or simply "embodiment" mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment.

Furthermore, in one or more embodiments, specific features, structures, or characteristics may be combined in any suitable manner.

[0039] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0040] In a first aspect, this application proposes an integrated ultrasonic scalpel, which includes a housing 110, a transducer disposed within the housing 110, a trigger assembly 130 partially disposed within the housing 110, a shaft assembly 140 rotatably connected to the housing 110, an excitation assembly 150 connected to the housing 110, a cable 160, and a conductive socket 170, wherein the cable 160 is electrically connected to the conductive socket 170; the transducer includes

[0041] The transducer housing is rotatably connected to the housing 110;

[0042] The transducer core 121 is connected to one end of the transducer housing via a buffer and is used to connect to the waveguide to transmit ultrasonic vibrations to the waveguide.

[0043] Stacking unit 122 is fixedly connected to transducer core 121 and is used to convert electrical energy into ultrasonic vibration;

[0044] The conductive plug 127 is electrically connected to the stacking unit 122 and is connected to the other end of the transducer housing. The conductive plug 127 is used to rotatably connect to the conductive socket 170 to transfer electrical energy to the stacking unit 122.

[0045] The ultrasonic scalpel shaft assembly 140 includes an outer tube, an inner tube, and a waveguide disposed within the inner tube. The outer tube, inner tube, and waveguide are connected by pins, allowing them to rotate synchronously. The inner tube can also move relative to the outer tube. The distal ends of both the outer and inner tubes are rotatable with clamping arms, so that when the inner tube reciprocates relative to the outer tube, the clamping arms open and close. Figure 1 As shown, the shaft assembly 140 also includes a dial wheel 141, with the proximal end of the outer tube connected to the dial wheel 141, so that the rotation of the dial wheel 141 around the axial direction can drive the outer tube, the outer tube, and the waveguide to rotate synchronously; the transducer housing is rotatably connected to the interior of the ultrasonic scalpel housing 110. In a specific embodiment, the transducer housing is rotatably connected by a clearance fit between the first support portion 111 and the first support portion 112; the transducer core 121 is threadedly connected to the waveguide for transmitting ultrasonic vibrations to the waveguide, and the transducer core 121 is connected to the transducer housing through a buffer. The connection between the transducer core 121 and the transducer housing through the buffer restricts the relative rotation between the transducer core 121 and the transducer housing, so that when the dial wheel 141 rotates, it drives the waveguide to rotate, and at the same time, it drives the entire transducer to rotate within the ultrasonic scalpel housing 110.

[0046] like Figure 1As shown, the trigger assembly 130 includes a trigger 131, a connecting rod 132, a slider 133, and a reset member 134. A portion of the trigger 131 is disposed within the housing 110 of the ultrasonic scalpel and is rotatably connected to the housing 110 to form a rotating shaft. The slider 133 is disposed inside the housing 110 and is slidably connected to the housing 110. One end of the connecting rod 132 is rotatably connected to one end of the slider 133, and the other end of the connecting rod 132 is rotatably connected to the trigger 131, so that when the trigger 131 reciprocates, it drives the slider 133 to reciprocate. One end of the reset member 134 is connected to the housing 110, and the other end is connected to the slider 133, used to reset the slider 133 after the trigger 131 drives the slider 133 to move. The shaft assembly 140 also includes an elastic element 142, which is connected to the proximal end of the inner tube. One end of the elastic element 142 is fixedly connected to the inner tube, and the other end abuts against the end of the slider 133 away from the connection position of the connecting rod 132. When the slider 133 reciprocates, it drives the inner tube to reciprocate along the axial direction. The elastic element 142 is used to apply a preset driving force to the inner tube so that the clamping arm applies a preset clamping force to the tissue clamped between the clamping arm and the cutting head.

[0047] like Figure 1 As shown, the transducer in the ultrasonic scalpel is connected to the main unit via a cable 160. One end of the cable 160 is fixedly connected to the housing 110, and the other end is provided with a plug, which is plugged into the corresponding socket of the main unit. Since the cable 160 is fixedly connected to the housing 110, and the transducer can rotate within the housing 110, the structure of the conductive plug 127 and the conductive socket 170 between the transducer and the cable 160 allows the transducer to rotate relative to the cable 160 while achieving a conductive connection. The conductive socket 170 is connected to the housing 110 and electrically connected to the cable 160. In one specific embodiment, the conductive plug 127 has a cylindrical structure and includes at least a positive plug terminal and a negative plug terminal, which are insulated from each other. The corresponding conductive socket 170 is circular and includes at least a positive socket terminal and a negative socket terminal, which are insulated from each other. When the conductive plug 127 is inserted into the conductive socket 170, the positive plug terminal and the positive socket terminal are in contact and connected, and the negative plug terminal and the negative socket terminal are in contact and connected. At the same time, the conductive plug 127 can rotate relative to the conductive socket 170.

[0048] The stacking unit 122 includes multiple piezoelectric ceramics and positive and negative electrodes disposed between each piezoelectric ceramic. The stacking unit 122 has an overall tubular structure and is pressed to the end of the transducer core 121 away from the waveguide by bolts 123. The positive terminal of the conductive plug 127 is electrically connected to the positive electrode, and the negative terminal is electrically connected to the negative electrode, thereby applying the electrical energy transmitted from the host to both ends of each piezoelectric ceramic. The piezoelectric ceramic converts the electrical energy into ultrasonic vibration, which is then transmitted to the waveguide through the transducer core 121. After vibration wave amplification and other processing by the waveguide, it is transmitted to the cutting head and finally acts on the clamped tissue to achieve cutting and / or coagulation of the clamped tissue.

[0049] like Figure 1 As shown, the excitation assembly 150 includes at least one excitation switch, which is fixedly mounted on the housing 110 and electrically connected to the cable 160. When the excitation switch is activated, it generates an excitation signal, which is transmitted to the host computer via the cable 160 to instruct the host computer to output power to the transducer. In some embodiments, the excitation assembly 150 includes a first excitation switch and a second excitation switch. The two excitation switches are used to generate different control signals to instruct the host computer to provide different power outputs to the transducer. In some specific embodiments, the first excitation switch is a high-power output switch, and the second excitation switch is a low-power output switch.

[0050] In one embodiment, such as Figure 2 As shown, the transducer housing includes an upper shell 124, a middle shell 125, and a lower shell 126. The upper shell 124 and the lower shell 126 are respectively connected to the two ends of the middle shell 125 to form a receiving cavity. A part of the transducer core 121 and the stacking unit 122 are disposed in the receiving cavity. The conductive plug 127 is plugged into the lower shell 126.

[0051] The upper shell 124 and the lower shell 126 are connected to the middle shell 125 by a snap-fit ​​method.

[0052] like Figure 3 As shown, the upper shell 124 includes an upper outer shell body 124-1, which includes a side wall and an end wall. The side wall is annular, and the end wall is fixedly connected to one end of the side wall. When a snap-fit ​​connection is used, multiple first snap-fit ​​protrusions 124-3 are provided on the inner side of the side wall away from the end wall. These first snap-fit ​​protrusions 124-3 are used for snap-fit ​​connection with the middle shell 125. Multiple reinforcing ribs 124-5 are provided at the connection point between the inner side wall and the end wall to strengthen the connection between the side wall and the end wall. A clearance hole is provided at the center of the end wall for the transducer core 121 to pass through the receiving cavity. Additionally, multiple perforations 124-2 are arranged circumferentially near the side wall for heat dissipation, and a buffer groove 124-4 is provided around the clearance hole on the inner side of the end wall to accommodate a buffer component.

[0053] like Figure 4As shown, the middle shell 125 includes a middle outer shell body 125-1, which is tubular, with its first end connected to the upper shell 124 and its second end connected to the lower shell 126. When a snap-fit ​​connection is used, the outer wall of the first end is provided with a plurality of first snap-fit ​​grooves 125-2 evenly spaced around the circumference, and a second snap-fit ​​groove 125-4 arranged in a ring around the circumference. Each of the first snap-fit ​​grooves 125-2 extends along the axis of the middle shell 125 and communicates with the second snap-fit ​​groove 125-4. The number of first snap-fit ​​grooves 125-2 is greater than or equal to the number of first snap-fit ​​protrusions 124-3 on the upper shell 124. When the upper shell 124 is snap-fitted to the first end, each first snap-fit ​​protrusion 124-3 corresponds to a first snap-fit ​​groove 125-2 and slides into the second snap-fit ​​groove 125-4 through the first snap-fit ​​groove 125-2. Then, the upper shell 124 is rotated by a preset angle so that at least a part of the first snap-fit ​​protrusion 124-3 coincides with the protrusion between the two first snap-fit ​​grooves 125-2, thereby preventing the upper shell 124 from detaching from the first end of the middle shell 125. In addition, the end face of the first end is provided with a plurality of buffer protrusions 125-3 spaced axially. These buffer protrusions 125-3 are connected to the buffer member to restrict the radial movement and axial rotation of the buffer member relative to the first end. When a snap-fit ​​connection is used, the outer wall of the second end is provided with a third snap-fit ​​groove 125-7 circumferentially, which is used to snap-fit ​​with the lower shell 126. In a specific embodiment, the end face of the second end is provided with at least one limiting groove 125-6, which is used to connect with the lower shell 126 to restrict the axial rotation of the lower shell 126 relative to the second end.

[0054] like Figure 5As shown, the lower shell 126 includes a lower outer shell body 126-1, which includes a side wall and an end wall. The side wall is tubular, and the end wall is fixedly connected to one end of the side wall. When a snap-fit ​​connection is used, a second snap-fit ​​protrusion 126-7 arranged in a ring is provided on the inner side of the side wall away from the end wall. The second snap-fit ​​protrusion 126-7 is used to engage with the third snap-fit ​​groove 125-7 to at least restrict the lower shell 126 from axially disengaging from the middle shell 125. In addition, the lower shell 126 is provided with a plurality of dividing grooves 126-4 along the circumferential side wall so that the side wall of the lower shell 126 forms a plurality of cantilever snap-fit ​​parts. Specifically, a plurality of dividing grooves 126-4 are provided on the side wall away from the end wall. The dividing grooves 126-4 extend from the end face of the side wall away from the end wall along the axial direction of the lower shell 126, thereby dividing the side wall away from the end wall into a plurality of cantilever structures. The cantilever structure has better flexibility, so that the lower shell 126 and the second end of the middle shell 125 are connected with appropriate plastic deformation so that the second snap-fit ​​protrusion 126-7 slides and snaps into the third snap-fit ​​groove 125-7 to form a snap-fit. In another specific embodiment, at least one limiting protrusion 126-8 is provided on the inner side of the side wall. The limiting protrusion 126-8 is used to cooperate with the limiting groove 125-6 at the second end of the middle shell 125 to restrict the rotation of the lower shell 126 relative to the second end after the lower shell 126 is connected to the second end of the middle shell 125.

[0055] In another embodiment, the lower housing 126 includes at least one through hole for the passage of a connecting wire between the conductive plug 127 and the stacking unit 122.

[0056] The electrical connection between the conductive plug 127 and the stacking unit 122 is achieved using a flexible wire connection. This minimizes contact between the stacking unit 122 and other components, improving the performance of the stacking unit 122 and reducing vibration issues such as howling caused by contact between other components and the stacking unit 122. To facilitate the connection between the wire and the conductive plug 127, at least one through-hole is provided inwardly on the side wall of the lower housing 126. Specifically, as shown in... Figure 5In the embodiment shown, the wiring holes include a first wiring hole 126-2 and a second wiring hole 126-3. When connecting the stacked unit 122 connected to the transducer core 121 and the conductive plug 127, a wire of a preset length can be used for connection first. Then, the connected conductive plug 127 is inserted from the first end of the middle shell 125 and exited from the second end of the middle shell 125. Further, the wire is passed through the wiring hole through the lower shell 126. Finally, the lower shell 126 is snapped together with the second end. In another embodiment, the wire hole can also be a through hole provided on the end wall of the lower outer shell 126-1. When the through hole is larger than the maximum diameter of the conductive plug 127, the conductive plug 127 can be connected to the stacking unit 122 wire first, then the conductive plug 127 can be inserted from the first end of the middle shell 125 and exited from the second end, and then the conductive plug 127 can be passed through the wire hole. Finally, the lower shell 126 can be snapped to the second end. Alternatively, when the through hole is smaller than the maximum diameter of the conductive plug 127, the wire can be connected to the stacking unit 122 first, then the wire can be inserted from the first end of the middle shell 125 and exited from the second end, and then the wire can be passed through the wire hole of the lower shell 126 and connected to the conductive plug 127. Finally, the lower shell 126 can be snapped to the second end. However, this solution with a smaller wire hole is more complicated in the assembly process than the previous two solutions. In another embodiment, a through hole can be opened on the end wall of the lower outer shell 126-1. Further, a contact electrode is provided on the outside of the end wall, and a part of the contact electrode passes through the through hole. During connection, the wire can be connected to the stacking unit 122 first, and then the wire can be inserted from the first end of the middle shell 125 and exited from the second end. The wire can be further connected to the contact electrode, and then the lower shell 126 can be snapped into the second end. Finally, when the conductive plug 127 is detachably inserted into the lower shell 126, the conductive plug 127 abuts against the contact electrode to conduct electricity.

[0057] In another embodiment, the circumferential sidewall of the middle shell 125 is provided with heat dissipation holes 125-5, specifically, as shown in... Figure 4 As shown, a plurality of heat dissipation holes 125-5 are provided on the sidewall between the first end and the second end for heat dissipation of the stacked unit 122.

[0058] In another embodiment, the end face of the lower shell 126 away from the middle shell 125 is provided with a plug slot 126-6 and a plurality of wire-locking parts 126-5 arranged around the plug slot 126-6. The conductive plug 127 is inserted into the plug slot 126-6, and the plurality of wire-locking parts 126-5 are used to fix the wires.

[0059] The conductive plug 127 is a metal conductive component, while the lower housing 126 is generally made of a different material than the conductive plug 127. The conductive plug 127 and the lower housing 126 are independently manufactured parts; therefore, a connection structure for the conductive plug 127 needs to be provided on the lower housing 126, such as... Figure 5 As shown, a plug slot 126-6 is provided on the end face of the lower shell 126 away from the middle shell 125. The plug slot 126-6 is a tubular structure extending from the end face of the lower shell 126 away from the middle shell 125 along the axial direction of the lower shell 126. At least one groove is formed in the side wall of the tubular structure to avoid the wire connection portion of the positive and / or negative terminals of the conductive plug 127. In addition, since the stacking unit 122 is connected to the conductive plug 127 by wires, in actual connection and assembly, in order to facilitate assembly, the wire length will be larger than that when the lower shell 126 and the middle shell 125 are connected at the second end, and the distance between the lower shell 126 and the stacking unit 122 will be increased by a factor of two. Therefore, when the lower shell 126 and the middle shell 125 are snapped together and the conductive plug 127 is inserted into the plug slot 126-6 of the lower shell 126, there will be redundant wires. To better constrain the redundant wires, multiple wire-holding portions 126-5 are provided on the end face of the lower shell 126 away from the middle shell 125, surrounding the plug slot 126-6. In a specific embodiment, as shown... Figure 5 As shown, the wire-locking portion 126-5 consists of a plurality of plate-shaped protrusions extending from the end face of the lower housing 126 and arranged around the plug slot 126-6, and each plate-shaped protrusion has at least one wire groove, which is used to support the wire groove and to fix the wire.

[0060] In another embodiment, the housing of transducer 120 is made of plastic.

[0061] In the integrated ultrasonic scalpel, the transducer housing is made of plastic. Plastic allows for better injection molding of the upper shell 124, middle shell 125, and lower shell 126, enabling one-time injection molding without additional machining processes. This significantly reduces the processing cost of the housing. Furthermore, plastic's superior flexibility makes it more suitable for snap-fit ​​connections, facilitating assembly. In contrast, traditional metal-cased transducers use interference fit connections, requiring machining of the metal shell, greatly increasing processing costs and complicating assembly. Additionally, plastic housings are lighter, and since the integrated ultrasonic scalpel's transducer is hidden inside the ultrasonic scalpel housing 110, the shape, texture, and aesthetics of the transducer housing are significantly reduced compared to a separate, reusable transducer. Therefore, considering the differences in manufacturing process, assembly process, and aesthetics compared to a separate, reusable transducer, the integrated ultrasonic scalpel uses a plastic transducer.

[0062] In another embodiment, the buffer includes a first buffer 128 and a second buffer 129, the first buffer 128 being used to support the transducer housing in a first direction along the transducer axial direction, and the second buffer 129 being used to support the transducer housing in at least a second direction along the transducer axial direction, wherein the first direction and the second direction are opposite.

[0063] The connection between the transducer housing and the transducer core 121 needs to restrict their relative movement along the axial direction and radial direction of the transducer core 121, and to ensure that the transducer housing rotates synchronously with the transducer core 121, it is further necessary to restrict the rotation of the transducer housing relative to the transducer core 121 about the axial direction. However, the transducer core 121 experiences ultrasonic vibration during transducer operation. If the transducer housing and transducer core 121 are rigidly connected, it will affect the transducer's vibration performance and cause a whistling problem at the connection point. Therefore, the transducer core 121 is indirectly connected to the transducer housing via a buffer component. The buffer component solves the whistling problem and reduces the impact on the transducer's vibration performance. Figure 2 As shown, the buffer includes a first buffer 128 and a second buffer 129. The first buffer 128 is an O-ring, and the second buffer 129 is an L-shaped rubber ring. The first buffer 128 is disposed between the flange 121-1 of the transducer core 121 and the buffer groove 124-4 of the upper shell 124, and is located within the buffer groove 124-4. It restricts the movement of the upper shell 124 relative to the transducer core 121 towards the proximal end of the transducer, i.e., in the first direction of the transducer's axial direction, thus supporting the upper shell 124 along the first direction. The second buffer 129 is disposed between the flange 121-1 of the transducer core 121 and the buffer protrusion 125-3 of the middle shell 125. Figure 6As shown, the second buffer 129 includes a buffer body 129-1, and a buffer protrusion 129-2 and a buffer groove 129-3 disposed on the buffer body 129-1. In a specific embodiment, the buffer protrusion 129-2 and the buffer groove 129-3 are arranged in a one-to-one correspondence, which is more conducive to the design of the structural strength of the second buffer 129. The buffer protrusion 129-2 cooperates with the groove on the transducer flange 121-1, thereby restricting the radial and axial relative movement of the second buffer 129 relative to the transducer core 121. The buffer groove 129-3 cooperates with the buffer protrusion 125-3, thereby restricting the radial and axial relative movement of the second buffer 129 relative to the middle shell 125. In addition, the cross-section of the second buffer 129 is L-shaped, wherein a part of the L-shaped buffer is located between the transducer flange 121-1 and the middle shell 125, and the other part is disposed around the outside of the transducer flange 121-1, thereby realizing the movement of the middle shell 125 along the transducer core 125. The transducer core 121 is limited in the radial and axial directions of the second direction to support the middle shell 125 in the second and radial directions of the transducer core 121. At the same time, since the upper shell 124 is snapped to the middle shell 125, that is, the upper shell 124 and the middle shell 125 are connected as a whole by snapping, and the transducer core 121 supports the upper shell 124 in the first direction, which is opposite to the second direction, the transducer flange 121-1 is surrounded and clamped by the first buffer 128 and the second buffer 129, so that the transducer core 121 achieves the purpose of supporting the transducer shell through the first buffer 128 and the second buffer 129.

[0064] In another embodiment of this application, the upper shell 124, the middle shell 125, and the lower shell 126 are connected by a threaded connection. When the threaded connection is used, the inner walls of the upper shell 124 and the lower shell 126 are provided with internal threads, and the outer walls of the first and second ends of the middle shell 125 are provided with external threads. The upper shell 124 is threaded to the external thread of the first end, and the lower shell 126 is threaded to the external thread of the second end.

[0065] Secondly, this application proposes an ultrasonic scalpel system, which includes an ultrasonic host and an integrated ultrasonic scalpel as described in any of the above claims. The host is electrically connected to the integrated ultrasonic scalpel and is used to provide power to the integrated ultrasonic scalpel.

[0066] The ultrasonic scalpel main unit includes multiple ultrasonic scalpel cable 160 connectors, allowing one ultrasonic scalpel main unit to connect to multiple ultrasonic scalpels simultaneously.
