[0040] In conjunction Figures 1 to 3 According to a specific embodiment of the present application, a conductive structure for an ultrasonic knife is provided.

[0041] Specifically, the conductive structure for the ultrasonic knife comprises a fixing seat 30, a first conductive ring 10, and a second conductive ring 20. The fixing seat 30 has a mounting hole 300. The first conductive ring 10 is connected to the fixing seat 30. The first conductive ring 10 is provided with at least one first protrusion 101. The first protrusion 101 has a first contact position in contact with a transducer. The first conductive ring 10 is used to be electrically connected with a switch of the ultrasonic knife. The second conductive ring 20 is connected to the fixing seat 30. The second conductive ring 20 is provided with at least one second protrusion 201. The second protrusion 201 has a second contact position in contact with the transducer. The second conductive ring 20 is used to be electrically connected with the switch. Wherein, the moment generated when the first protrusion 101 is located at the first contact position is opposite in direction to the moment generated when the second protrusion 201 is located at the second contact position.

[0042] In conjunction Figure 1 and Figure 6As shown, the mounting hole 300 is used to mount the transducer, the first conductive ring 10 is electrically connected with the switch of the ultrasonic knife 40, and the second conductive ring 20 is electrically connected with the switch of the ultrasonic knife 40. When the first conductive ring 10 and the second metal ring 52 of the transducer are in contact, and the second conductive ring 20 and the first metal ring 51 of the transducer are in contact, the torque directions generated by the first protrusion 101 and the second protrusion 201 when in contact are opposite. This symmetrical torque balance mechanism eliminates the force imbalance that may be caused by asymmetric connection, thereby avoiding the problem of poor contact and ensuring the stability and safety of the ultrasonic knife during the operation.

[0043] In an optional embodiment of the present application, the first protrusion 101 is a plurality of first protrusions 101, each first protrusion 101 has a first contact position when in contact with the transducer, and the directions of the torques generated by the plurality of first protrusions 101 when located at the first contact positions are opposite to the direction of the torque generated by the second protrusion 201 when located at the second contact position. When there are a plurality of first protrusions 101 on the first conductive ring 10, the directions of the torques generated by each first protrusion 101 when in contact with the second metal ring 52 of the transducer all point to the center of the fixed seat 30. Since the plurality of first protrusions 101 are distributed along the circumference of the first conductive ring 10, the direction of the resultant torque generated by the plurality of first protrusions 101 will be more concentrated and stable, and can more effectively counteract the torque generated by the second protrusion 201 on the second conductive ring 20, thereby achieving torque balance of the entire conductive structure.

[0044] In an optional embodiment of the present application, the second protrusion 201 is a plurality of second protrusions 201, each second protrusion 201 has a second contact position when in contact with the transducer, and the directions of the torques generated by the plurality of first protrusions 101 when located at the first contact positions are opposite to the directions of the torques generated by the plurality of second protrusions 201 when located at the second contact positions.

[0045] The resultant torques generated by the plurality of first protrusions 101 on the first conductive ring 10 are opposite to the resultant torques generated by the plurality of second protrusions 201 on the second conductive ring 20. When the transducer 50 is installed in place, the resultant torques generated by the first conductive ring 10 and the second conductive ring 20 will cancel each other out, thereby ensuring stable positioning of the conductive structure assembly in the entire ultrasonic knife system. In addition, the first protrusion 101 and the second protrusion 201 are both provided in a plurality, so that even if various external forces are encountered during the operation, the conductive structure can remain stable, thereby avoiding affecting the stability of the overall electrical connection due to the failure of a single contact point, and ensuring normal operation of the equipment and safety of the operator during the operation.

[0046] In an optional embodiment of the present application, the number of first protrusions 101 is equal to the number of second protrusions 201.

[0047] Further, the direction of the moment generated when the first protrusion 101 is at the first contact position is across the axis of the mounting hole 300. This arrangement not only ensures electrical contact between the first conductive ring 10 and the transducer 50, but also aligns the axis to allow the moment to act on the center point of the entire structure, thereby improving the transmission efficiency of the moment and the stability of the conductive structure.
