Runner is assemblied in inside cutter head handle；The rotating wheel includes mounting portion and clicking section, and mounting portion is connect with knife bar, cutter head handle
Top, which is opened up, stirs slot for what clicking section was exposed.
In above scheme, rotating wheel is arranged on cutter head handle, can further the distance between thumb and rotating wheel, pass through
Thumb manipulation clicking section makes rotating wheel drive knife bar rotation, achievees the purpose that adjust cutter head jaw direction.Due to different operations
The length difference of person's thumb is less than the length difference of index finger, and the structure adjusted by thumb is arranged, can convenient more operations
Person.Again due to being thumb manipulation by index finger operation change, remaining four finger is more stable to the gripping of cutter head handle, and surgical procedure is more smart
It is quasi- laborsaving, meet Human Engineering Principle.The cutter head structure of cutter head handle front end is arranged in the more existing knob of this component, adjusts knife
Head jaw direction is easier, and operation is more reliable and more stable, also more convenient safety.
For the operating characteristics for further increasing device, it is described stir slot and be opened in hold cutter head handle and carry out operation Shi Yu great
Thumb position corresponding position.
For the connection for realizing rotating wheel and knife bar, the mounting portion includes the first sleeve and second sleeve axially connected,
The diameter of second sleeve is less than first sleeve；The first sleeve is connect with clicking section, and second sleeve is connect with knife bar.
Further, the second sleeve opens up radial pin hole, and second sleeve is connect with knife bar by pivot pin.
Further, the mounting portion and clicking section integrated injection molding.
The utility model also provides a kind of ultrasound knife, including ultrasonic transducer and above-mentioned ultrasound knife cutter head assembly, described super
Sonic transducer is accessed from cutter head handle caudal, and head end and rotating wheel are cooperatively connected.
The advantages of the utility model, is with effect:
1, rotating wheel is arranged on cutter head handle, the distance of furthered thumb and rotating wheel, can be dialled by thumb manipulation
Dynamic portion and adjust cutter head jaw direction, remaining four refers to and holds to cutter head handle that the structure is arranged than current rotating wheel in knife
First hand front end, in such a way that index finger stirs cutter head jaw direction it is more reliable and more stable precisely, also more convenient safety；
2, the length difference of thumb is significantly less than the length difference of index finger between different operators, can by thumb control
To widen use scope, it is suitable for more operators；
3, after changing rotating wheel onto cutter head handle in front of cutter head handle, cutter head rotating wheel and patient's pneumoperitoneum be can avoid
On puncture outfit contact, be equivalent to the effective length increase at least 20mm of ultrasonic knife bar, entire ultrasound knife cutter head can reach
The anatomical position in more deep improves the range of clinical application.
