An endoscopic surgical instrument is revealed herein, comprising a main body for control thereof, an outer tube, and a repair tool and an electrosurgical assembly. The outer tube fitted on a front end of the main body has an oblique incision on an external end thereof, and the repair tool passes through the inside of the outer tube to allow its cutting portion to be half exposed to the oblique incision. In this way, the electrosurgical assembly may be fitted at a position in the opening direction of the oblique incision. As a result, a wound can be electro-coagulated in a real-time manner when cutting injured tissue of a joint in the course of an arthroscopic surgery by use of the instrument, so as to swiftly stop bleeding and go forward with surgical procedures without obstacles.本發明係有關於一種內視鏡手術器具,其主要包含有一握持主體,於該握持主體前端設有一外管件,該外管件外側端形成一斜切口,且於外管件內部穿設一修護刀具,以讓該修護刀具之切削刀部半露於斜切口處,以對應切削關節組織,而於斜切口開口方向的區域位置可設置電燒組件;藉此,於器具運用在關節鏡手術進行的過程中,在切除關節受損組織的當下,即時進行傷口燒結,達到迅速止血且不阻礙手術進行的功效者。(2)‧‧‧外管件(21)‧‧‧斜切口(22)‧‧‧電燒組件(3)‧‧‧修護刀具(31)‧‧‧切削刀部(X)‧‧‧區域位置
