The waveguide rod portion 280 is threadedly coupled to the ultrasonic transducer 7, and one end of the waveguide rod portion 280 is provided with an opening (not shown) for being fitted to the fixing member 70 of the ultrasonic transducer 7, such that when the cutter bar assembly 28 is coupled to the ultrasonic transducer 7, the waveguide rod portion 280 of the cutter bar assembly 28 can be moved from the first position to the second position in a direction approaching the base 20, so that the waveguide rod portion 280 of the cutter bar assembly 28 and the ultrasonic transducer 7 are changed from an unstable coupled state to a stable coupled state. That is, when the waveguide rod 280 of the cutter bar assembly 28 is in the first position, the length of the opening of the fixture 70 of the ultrasonic transducer 7 into the waveguide rod 280 of the cutter bar assembly 28 is smaller than the length of the opening of the fixture 70 of the ultrasonic transducer 7 into the waveguide rod 280 of the cutter bar assembly 28 when the cutter bar assembly 28 is in the second position, such that when the waveguide rod 280 of the cutter bar assembly 28 is moved from the first position to the second position, the waveguide rod 280 of the cutter bar assembly 28 and the ultrasonic transducer 7 are changed from an unstable connection state to a stable connection state.
Referring to fig. 1 and 4-5, the wrench 6 is used to mount the blade bar assembly 28 of the ultrasonic surgical instrument 2 to the ultrasonic transducer 7 for connection to an ultrasonic generator (not shown) so that the ultrasonic generator can power the blade bar assembly 28 of the ultrasonic surgical instrument 2 through the ultrasonic transducer 7.
Specifically, the wrench 6 includes a main body 60 and an abutment 61. The main body 60 is provided with a mounting through hole 600 penetrating the main body 60 in the axial direction, wherein the mounting through hole 600 is for guiding the waveguide rod portion 280 of the cutter bar assembly 28 therethrough. In the present embodiment, the main body 60 has a substantially cylindrical shape, and the mounting through hole 600 is provided in the middle of the main body 60. Of course, the shape of the main body 60 and the installation position of the installation through hole 600 are not limited thereto.

Of course, the connection manner of the abutting portion 61 and the main body 60 is not limited thereto.
Wherein, when the waveguide rod 280 of the cutter bar assembly 28 is at the first position (i.e. the waveguide rod 280 of the cutter bar assembly 28 is in an unstable connection state with the ultrasonic transducer 7), the abutment 61 is located at one side of the tooth 22; when the waveguide rod portion 280 of the cutter bar assembly 28 is located at the second position (i.e., the waveguide rod portion 280 of the cutter bar assembly 28 is in a stable connection with the ultrasonic transducer 7), the abutment 61 is located on the other side of the tooth 22. In this way, the operator may consider the arbor assembly 28 and the ultrasonic transducer 7 to be already in a stable connection when the force acting on the wrench 6 to drive the waveguide rod portion 280 of the arbor assembly 28 in rotation is sufficient to drive the teeth 22 of the ultrasonic surgical instrument 2 slidingly against the abutment 61 of the wrench 6. When the cutter bar assembly 28 of the ultrasonic surgical instrument 2 is mounted on the ultrasonic transducer 7, no additional auxiliary tool is needed, and the ultrasonic surgical instrument is simple in structure and convenient to use.

In this way, when the force acting on the wrench 6 to drive the rotation of the knife bar assembly 28 is sufficient to drive the teeth 22 of the ultrasonic surgical instrument 2 slidingly against the abutment 61 of the wrench 6, the first abutment surface 221 of the teeth 22 of the ultrasonic surgical instrument 2 abuts against the first abutment surface 611 of the abutment 61 to drive a deformation of a portion of the abutment 61.
In the present embodiment, the first abutment surface 611 is an inclined surface or a curved surface, and the first abutment surface 221 is an inclined surface or a curved surface. Optionally, the first abutment surface 611 is arc-shaped or has a rounded chamfer. Of course, the shapes of the first abutment surface 611 and the first abutment surface 221 are not limited thereto.
In the present embodiment, the other side of the abutment 61 has a second abutment surface 612, the second abutment surface 612 being configured to abut against a second abutment surface 222 located on the other side of the lobe 22 of the ultrasonic surgical instrument 2 to prevent the waveguide rod 280 of the knife bar assembly 28 from moving from the second position to the first position. In this way, the waveguide rod portion 280 of the cutter bar assembly 28 can be prevented from being changed from a stable connection state to an unstable connection state with the ultrasonic transducer 7.
Optionally, the second abutment surface 612 is planar, and the second abutment surface 222 is planar. Of course, the shapes of the second abutment surface 612 and the second abutment surface 222 are not limited thereto.
Optionally, the abutment 61 of the main body 60 is provided with a groove 602, the abutment 61 comprises a connecting portion 613 extending from a side wall of the groove 602 and a clamping portion 614 extending from a side of the connecting portion 613 away from the side wall of the groove 602, wherein the connecting portion 613 has elasticity to be in an elastically deformed state when the abutment of the teeth 22 of the ultrasonic surgical instrument 2 is pressed close to the axis of the main body 60 to have a tendency to prevent the connecting portion 613 from moving towards the axis close to the main body 60, and the first abutment surface 611 and the second abutment surface 612 are provided on the clamping portion 614. Alternatively, the groove 602 communicates with the mounting through hole 600 of the main body 60. In this way, when the tooth 22 of the ultrasonic surgical instrument 2 slides onto the abutment 61, the tooth 22 of the ultrasonic surgical instrument 2 presses against the catching portion 614 of the abutment 61 to bring the connecting portion 613 of the abutment 61 into an elastically deformed state toward the side of the mounting through hole 600 near the groove 602.
Optionally, the wrench 6 further includes a wing portion 66 disposed on the outer side of the main body 60, and the wing portion 66 is provided with a hollowed-out hole 660. In this embodiment, there are two wings 66 and they are disposed opposite each other. Thus, the wrench 6 can be conveniently operated, and the hollow hole 660 can lighten the weight of the wrench 6 and strengthen the structural strength and the aesthetic degree of the wrench 6.
Optionally, the ultrasonic surgical instrument 2 comprises a number of teeth 22 and the wrench 6 comprises a number of abutments 61. Wherein, the number is at least 2. The number of the teeth 22 and the number of the abutment portions 61 may correspond.
The second embodiment of the present invention also provides a wrench 6 as above for mounting an ultrasonic surgical instrument 2.
In the wrench 6 provided by the embodiment of the invention, the wrench 6 comprises the abutting part 61 for slidably abutting against the convex tooth 22 of the ultrasonic surgical instrument 2, and when the waveguide rod 280 of the cutter bar assembly 28 is in the first position (namely, the waveguide rod 280 of the cutter bar assembly 28 is in an unstable connection state with the ultrasonic transducer 7), the abutting part 61 is positioned at one side of the convex tooth 22; when the waveguide rod portion 280 of the cutter bar assembly 28 is located at the second position (i.e., the waveguide rod portion 280 of the cutter bar assembly 28 is in a stable connection with the ultrasonic transducer 7), the abutment 61 is located on the other side of the tooth 22. In this way, by observing and judging the position of the abutment portion 61 relative to the tooth 22, it is possible to judge whether the waveguide rod portion 280 of the cutter bar assembly 28 and the ultrasonic transducer 7 are in a stable connection state, and when the waveguide rod portion 280 of the cutter bar assembly 28 of the ultrasonic surgical instrument 2 is mounted on the ultrasonic transducer 7, no additional auxiliary tool is needed, and the structure is simple and the use is convenient.
