でに多くの時間を要するという欠点を有していた。[Problems to be Solved by Conventional Techniques and Inventions] Conventionally, joint surgery has been performed mainly by an incision method (open surgery). For example, in general joint surgery, tumors on the patella are excised, damaged cartilage, bone, etc. are excised from the knee joint, but these operations require relatively large incisions. I was there. For this reason, there is a drawback in that trauma due to incision is caused, pain and movement limitation are involved, and it takes a long time to completely recover.

できない部位が発生するという問題点があった。Therefore, in recent years, under the observation of an arthroscope (endoscope), a surgical excision instrument for performing a surgical operation by forming a small puncture hole in this joint without incising the joint and inserting an insertion portion into this puncture hole has been developed. Proposed. For example, in Japanese Unexamined Patent Publication No. 61-170449, a pair of notched blades is provided at the tip of a hard, linearly extended outer tube, and the pair of notched blades smoothly slides along a straight line and a curved line. A surgical cutting instrument having an outer blade having a formed cutting edge and an inner blade made of a helical cutter blade rotatably mounted in the outer tube is disclosed. However, in this conventional technique, the tissue to be cut is taken in between the outer blade made of a pair of notched blade portions, and when cutting and cutting by rotation of the inner blade, the cutting edge in the outer blade is straight and curved. Since it is configured to be smooth with and, the tissue to be cut escapes from between the pair of notched blade portions, and there is a problem that there is a portion that cannot be excised by any means.
