Embodiment Construction
[0111] Refer below Figure 1A and Figure 1B The first embodiment of the present invention will be described. Figure 1A The overall schematic configuration of the ultrasonic treatment instrument 12 according to this embodiment is shown. The ultrasonic treatment instrument 12 has a grip portion 14 that is gripped by an operator. An ultrasonic vibrator 17 that generates ultrasonic vibrations is accommodated in a main body portion 16 of the grip portion 14 . In this embodiment, a bolted Langevin type transducer (BLT: Bolt-clamped Langevin Type Transducer) is used as the ultrasonic transducer 17 . In addition, the ultrasonic vibrator 17 may be a laminated piezoelectric bulk vibrator, a magnetostrictive vibrator, an electrostrictive polymer vibrator, an air gap type electrostatic actuator, or the like as long as it has a function of converting electrical vibration into mechanical vibration.
[0112] An output end 18 for outputting ultrasonic vibrations is disposed on the front e...

The present invention provides an ultrasonic treatment implement which comprises the following components: an ultrasonic transducer which generates ultrasonic vibration; an elongated vibration transmission connected with the ultrasonic transducer at the proximal end and transmits ultrasonic vibration from the proximal end to the distal end of component; and a treatment section which is installed at the distal end of the vibration transmission component and applies the ultrasonic vibration to the object to be treated. The treatment section is provided with a front end surface section which is provided with a holding part that can hold the object to be treated. The treatment section is provided with a small-diameter part extending from the proximal end to the distal end and a large-diameter part installed at the distal end of small-radius part. The outer diameter of at least one part of section of large-diameter part perpendicular to the longitudinal shaft of small-diameter part is larger than the outer diameter of at least one part of section of small-diameter part perpendicular to the longitudinal shaft of small-diameter part. The treatment part is provided with an edge-shaped edge part which is installed on the small-diameter part or between the small-diameter part and the large-diameter part.
Description
[0001] This application is a divisional application of the invention patent application with the filing date: May 31, 2005, the application number: 200580030802.6, and the invention title "ultrasonic treatment device, probe for ultrasonic treatment device, treatment part and large diameter part" . technical field [0002] The present invention relates to an ultrasonic treatment tool that applies ultrasonic vibrations to a treatment object to perform treatment. Background technique [0003] Conventionally, ultrasonic treatment instruments that apply ultrasonic vibrations to living tissue to perform treatment have been used. In such an ultrasonic treatment instrument, a probe is connected to an ultrasonic vibrator that generates ultrasonic vibrations, and the probe performs treatment using the ultrasonic vibrations transmitted from the ultrasonic vibrator. An example of such a probe is disclosed in US Patent No. 5,324,299. [0004] The probe of US Pat. No. 5,324,299 is a sur...
