System's one kind of the present invention has the ultrasonic auxiliary system of two groups of detecting units and the method using the system to simulate operation, the system includes: a probe, one first group of detecting unit, it includes a first transmitter and one first receiver, one second group of detecting unit, it includes a second transmitter and a second receiver, the perforation between first group of detecting unit of Ji Yiwei what and second group of detecting unit； An and image processing mould group. In an embodiment by the probe close to what analog detection object tissue, and first and second transmitter is towards analog detection object tissue emissions low frequency Supersonic wave ray, and it is pattern image by signal resolution and is sent to screen and shows, thereby using a surgical instrument to puncture the predetermined target placement to the analog detection object tissue from perforation place of the probe, to clamp the simulation lesion tissue in the position what analog detection object tissue, in order to the efficiency person for reaching the training simulation operation using ultrasonic auxiliary system.本發明係一種具有二組偵測單元之超音波輔助系統及使用該系統以模擬手術之方法，該系統包括：一探頭，一第一組偵測單元，其包括一第一發射器及一第一接收器，一第二組偵測單元，其包括一第二發射器及一第二接收器，及一位於第一組偵測單元與第二組偵測單元間之穿孔；及一影像處理模組。在一實施例將該探頭貼近於模擬探測物組織，而該第一及第二發射器朝向模擬探測物組織發射低頻超音波射線，並將信號解析為圖案影像及傳送至螢幕顯示，藉此利用一手術器械以從該探頭之穿孔處穿刺至該模擬探測物組織內之預定標靶位置，以夾取位於該模擬探測物組織內之模擬病灶組織，俾達到利用超音波輔助系統之訓練模擬手術之效能者。
