Amplitude detector for supersonic blade

Abstract

The disclosed detection device combining computer with general medical stereomicroscope provides following features: displaying amplitude of knifepoint on display, recording it in storage device of computer for further calling back and processing, low cost and simple structure. The detection device includes microscope, unit for fixing ultrasonic knife, the knife fixed on the unit connected to an ultrasonic operation device. Characters of the ultrasonic knife are: (1) camera through communication line is connected to computer, and the picked images are stored and displayed; (2) there is bar groove for knife body to be places on a flute of test board, ultrasonic; knife is suspended on the bar groove; a ruler bar is on side wall of the flute and knifepoint of the ultrasonic knife is aligned to zero line of the ruler bar.

Description

technical field [0001] The invention relates to an ultrasonic knife amplitude detection device, in particular to an ultrasonic knife amplitude detection device using a common medical stereo microscope as a detection workbench. Background technique [0002] Ultrasonic surgical device is a new type of surgical device that began to develop rapidly in the 1980s, and is known as a major breakthrough in the international medical field. Compared with high-frequency electric knife, laser knife and microwave knife, it has less damage to the tissue around the surgical site or section, less bleeding (or even no bleeding), clear surgical field of view, less surgical risk, high safety, and convenient operation. The series have outstanding advantages and are widely used in ophthalmic surgery, neurosurgery, tumor treatment and other surgical fields, and have become one of the high-tech medical products that are competing to be developed at home and abroad. [0003] At present, it is gener...

AI Technical Summary

Problems solved by technology

[0003] At present, it is generally believed at home and abroad that the key parameter for judging whether the ultrasonic surgical device is qualified is the axial offset of the main knife tip of the hand-held treatment head when the ultrasonic generator is working, that is, the amplitude of the treatment head. The general amplitude range is 32-350 μm. If the amplitude is too small, it will affect the operation effect and prolong the operation time. On the other hand, if the amplitude is too large, it will increase the difficulty of holding the treatment head and the manufacturing cost, and reduce the service life. Therefore, the amplitude is generally set between 200 and 350 μm

[0004] There is no effective detection equipment in China for the measurement of the amplitude of the hand-held treatment head. Generally, the method of direct...
