This creation department has a special bone knife for magnetic extensor sinus membrane peeling.The instrument for sinus membrane peeling for dental surgery includes a magnetic sensing device and a bone knife； wherein the magnetic sensing device includes an engaging opening, and the osteotome includes an engaging body, and the engaging opening can be used To engage the joint； the front end of the bone cutter includes a cutter on which a plurality of obliquely-rotating blades are disposed. The magnetic sensing device of the present invention can generate the phenomenon of back-and-forth oscillation, which can make the bone knife have better safety than the conventional one when peeling off the upper jaw and the sinus membrane. This case is rich in patent value and can improve the safety of surgery.本創作係有關於一種「磁伸式鼻竇膜剝離專用骨刀器械」，該種應用於牙科手術之鼻竇膜剝離用器械，包括有一感磁性裝置與一骨刀；其中該感磁性裝置包括有一接合口，至於該骨刀包括有一接合體，該接合口能用以接合該接合體；又該骨刀前端包括有一刀具，該刀具上設置有複數斜旋式刀片。利用本案之感磁性裝置能產生前後振盪之現象，能使骨刀相對於上顎骨與鼻竇膜進行剝離時具有較習知者更安全之優點。本案富具專利價值，且更能提升手術安全性。
