本発明は、切開することなく体腔外から体腔内、例えば
膝等の関節腔内の軟骨（関節半月、関節軟骨）、軟骨瘤

関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention can be used to remove cartilage (articular meniscus, articular cartilage), chondrocele, tumor, etc. from outside the body cavity to within the body cavity without making an incision, for example, in the joint cavity of the knee etc. This relates to a surgical resection instrument that excises and expels the body from the body cavity.

要としていた。[Problems to be solved by conventional techniques and inventions] Conventionally,
Joint surgery was primarily performed by the open method (open external oblique). For example, in general joint surgery, tumors on the patella are removed, or damaged cartilage is removed from the knee joint.
This involves removing bones, etc., but requires relatively large incisions.
そのため、切開による外傷を生じ、苦痛と運動制限とを
伴い、直るまでに多くの時間を要するという欠点を有し

等にこれらが開示されている。Therefore, in recent years, under observation using an arthroscope (endoscope), a small puncture hole is formed in the joint without incision, and a probe inserted into the puncture hole is used for surgery (closed surgery). A device has been proposed. For example, Special 1 [54-77
These are disclosed in No. 493, Special Publication No. 57-156753, etc.

材を経て吸引排出するように構成している。The device according to the prior art includes an elongated fixed outer tube in which a cutting opening extending in the axial direction or opening at the tip is formed on the outer periphery;
A tubular inner member rotatably housed within the outer tube and forming an internal rotary blade at the cutting opening, a main body, a suction device, and a drive motor are provided to remove tissue pieces, etc. into the cutting opening by vacuuming. At the same time, the rotary blade is rotated by the drive motor to perform cutting, and the cut pieces are suctioned and discharged through the tubular inner member.

切削性が悪いといった問題がある。However, these conventional instruments have a rotary blade for cutting, and since this rotary blade is installed inside an outer tube with a small inner diameter and is extremely small, advanced technology is required to process it. There are problems such as poor productivity. Furthermore, in conventional instruments, the insertion portion is formed in a straight line, and the cutting opening is also formed on the outer periphery or the tip of this linear part, making it difficult to see the cutting opening and making it difficult to target the target tissue. Further, the conventional instrument is configured to cut tissue using a milling rotary blade with a cutting edge, but it is particularly suitable for cutting tissues in body cavities, such as damaged joint meniscus, cartilage, etc. in the knee joint cavity.
Target tissues such as tumors are elastic and viscous, so
There are problems such as poor machinability.
