Embodiment Construction

[0069] Figure 1 ~ Figure 40B 1st Embodiment is shown. figure 1 The overall schematic structure of the handpiece 1 of the ultrasonic treatment device according to the present embodiment is shown. The ultrasonic treatment device according to the present embodiment is an ultrasonic coagulation and incision treatment device capable of performing high-frequency treatment at the same time as incision, excision, or coagulation of living tissue using ultrasonic waves.

[0070] Such as figure 2 As shown, the handpiece 1 includes four units of a vibrator unit 2 , a probe unit (probe unit) 3 , a handle unit (handle unit) 4 , and a sheath unit (sheath unit) 5 . These 4 units are respectively connected in a detachable manner.

[0071] A vibrator 6 described later is assembled inside the vibrator unit 2 (refer to Figure 36 ). The vibrator 6 is used to generate ultrasonic vibrations using a piezoelectric element that converts electric current into ultrasonic vibrations. The outside ...

Abstract

The present invention provides an ultrasonic operating apparatus which includes an ultrasonic transducer (6) which generates ultrasonic vibration, a probe unit (3) which is coupled to the ultrasonic transducer (6) and transmits the ultrasonic vibration from the ultrasonic transducer (6), an ultrasonic transducer unit (2) having a casing section (7) which stores the ultrasonic transducer (6), an electric cable (9) which is provided at a proximal end portion of the ultrasonic transducer unit (2), a handle unit (4) in which the probe unit (3) is inserted and which includes a coupling end portion for coupling to a distal end portion of the ultrasonic transducer unit (2), and a coupling section which couples an outer periphery of the distal end portion of the ultrasonic transducer unit (2) and a proximal end portion of the handle unit (4), wherein the coupling section includes a different-type assembly prevention section (140b) which prevents assembly between the ultrasonic transducer unit (2) and the handle unit (4) which are of different types.

Description

technical field [0001] The present invention relates to an ultrasonic treatment device capable of performing high-frequency treatment while using composite energy of ultrasonic waves and high-frequency to incise, resect or coagulate biological tissue. Background technique [0002] Generally, as an example of an ultrasonic treatment device that can perform high-frequency treatment while using ultrasonic waves to incise, resect, or coagulate living tissue, Japanese Patent Application Laid-Open No. 2003-265496 (Patent Document 1) Ultrasonic treatment apparatus described in JP-A-2005-278933 (Patent Document 2) and the like. [0003] The aforementioned Patent Document 1 discloses a structure in which the main body of an ultrasonic treatment device is assembled from three units, namely, a vibrator unit, a probe unit, and a handle unit. Here, an example of means for preventing erroneous assembly when assembling the three units of the vibrator unit, the probe unit, and the handle u...
