A mechanized punch for making cylindrical excision of hair follicles (10) is connected to an electronic instrument (60) and includes a tubular element (11) and a rectilinearly advancing rotary mechanism (20). The rectilinearly advancing rotary mechanism (20) includes a circle-cutting device (21) and a rectilinear movement module (40), in which the circle-cutting device (21) comprises a transmission shaft (22) having a first end connected with a drive element (25) and a second end connected with a chuck (23) so that the chuck (23) is allowed to clamp tight a tubular punch (24). When donor skin (52) is contacted by the tubular punch (24), the electronic instrument (60) actuates the drive element (25) to drive the transmission shaft (22) and the tubular punch (24) for rotation while the linear actuator (44) in the rectilinear movement module (40) drives the circle-cutting device (21) in a rectilinear forward motion until a cylindrical cut (53) of predetermined depth is made on the donor skin (52) by the punch (24).一種取毛囊用打孔器連接於一電子儀器,其包括一管狀元件;及一前進旋轉機構,安裝在該管狀元件內,其包含一打孔裝置及一控制模組。該打孔裝置具有一傳動軸其一端與一夾頭連結,該傳動軸的另一端與一驅動元件連結,並使該夾頭夾持有一針管;該控制模組具有一連接端子,一觸控傳感器及一行程控制器;當該針管接觸頭皮時,該觸控傳感器經由電子儀器啟動該驅動元件,並帶動該傳動軸旋轉,且同時帶動針管旋轉,及該行程控制器可精確地帶動該打孔裝置以直線前進,直到該針管在頭皮上打出一個預定深度的圓柱孔,接著使該針管復歸;完成上述打孔工作時,即可準備取出毛囊。10‧‧‧取毛囊用打孔器11‧‧‧管狀元件12‧‧‧手握管13‧‧‧帽蓋14‧‧‧第一管狀端部15‧‧‧第二管狀端部20‧‧‧前進旋轉機構21‧‧‧打孔裝置22‧‧‧傳動軸23‧‧‧夾頭24‧‧‧針管25‧‧‧驅動元件27‧‧‧連接端30‧‧‧按壓元件32‧‧‧伸縮桿40‧‧‧控制模組41‧‧‧支持板42‧‧‧連接端子43‧‧‧觸控傳感器50‧‧‧傳輸線
