A kind of medical diagnosis device and its medical system. Medical system includes external diagnostic device and medical diagnosis device. Medical diagnosis device includes line mould group, needle-shaped group die-filling group and micro process mould group. Line mould group is to send or receive line signal. Needle-shaped group die-filling group to detect lesion to generate detection signal or treatment lesion. Micro process mould system is electrically connected line mould group, and with needle-shaped group of die-filling group of mutual assembly and connection, micro process mould group detects obtained detection signal to receive needle-shaped group die-filling group, and via line mould group to be transmitted to external diagnostic device, or make external diagnostic device by needle-shaped group die-filling group to treat the lesion.一種醫療診斷裝置及其醫療系統。醫療系統包括外部診斷裝置及醫療診斷裝置。醫療診斷裝置包括連線模組、針狀組裝模組及微處理模組。連線模組用以傳送或接收連線訊號。針狀組裝模組用以偵測病灶以產生偵測訊號或治療病灶。微處理模組係電性連接連線模組，並與針狀組裝模組互相組裝連接，微處理模組用以接收針狀組裝模組所偵測得到之偵測訊號，並經由連線模組以傳輸至外部診斷裝置，或使外部診斷裝置藉由針狀組裝模組以治療該病灶。
