Development of new ultrasonic probe for intraoral use and clinical evaluation

设计了一种新的探头，以提高诊断和手术能力。该探头主要由一个内置直电缆的立方柱和一个扫描元件组成。加长的柱子对我们的抓握和处理很有用。扫描组件使临床医生能够识别受损病变的精确外观。探头外表面覆盖有坚硬的长方体圆柱体，但探头内的探测索包括有盖的水囊。该元件为直线型，检查视野范围为10 mm，采用脉冲多普勒方法进行扫描，在B模式下获得彩色断层图像。证明本研究所开发的水囊扩张器可与靶器官紧密接触。该仪器成功地获得了良好的分辨率和清晰的焦距。使用专门为口内使用而开发的新型超声探头，我们获得了正常的唇、舌、牙龈、腭、我们的超声波仪器对口腔和颊部的正常人的口腔底部的正常人基于这些发现，该探头由于其出色的可操作性和清晰图像的产生而非常有用。

A new probe was devised to improve the diagnostic and operative ability. This probe consisted mainly of a cubic column with straight cable inside and a scanning element. The prolonged column was useful for griping and handling at our discretion. The scanning component enabled clinicians to recognize a precise appearance of the impaired lesions. The outer surface of this probe was covered with hard cuboid column except the searching prove including covered water bag. This element was linear type and the range of examining view was 10 mm. Scanning was performed by the pulse Doppler method to obtain color tomograms in the B mode. The prove that we have developed in this study could make close contact with the target organs by expanding water bag. Good resolution and clear focal distance were successfully obtained by this devised instrument. Precise ultrasonic analysis of internal-, marginal-, posterior-, and vascular- echoes were indispensable for the accurate diagnosis.Using the new ultrasonic probe, especially developed for intraoral use, we obtained normal ultrasonic local images of the lip, tongue, gingiva, palate, floor of the mouth and cheeks of healthy individuals as by 0.1mm.Our ultrasonic instrument appears to be preferable for the accurate diagnosis of hampered disease in the oral cavity.Based on these findings, the probe was very useful due to its excellent operationality and production of sharp images.
