The utility model relates to a human operation intracavity exposes strutting arrangement relates to a surgery operation medical instrument, can extensively be used for the medical instrument of human operating field field extension. A human operation intracavity exposes strutting arrangement comprises exposed core no. 1, exposed core no. 2 and linkage segment, be provided with exposed core no. 1 in one side of linkage segment, the other end is provided with exposed core no. 2. The linkage segment be elastic material, elastic material is elasticity filament, adj. Tabular spring or coil spring, exposed core no. 1 is bracketing or clip. Exposed core policy of "literature and art should serve both people and socialism" bracketing or clip. The bracketing is U -shaped, V -arrangement or a plurality of U -shaped, V -arrangement side by side, and the bracketing is platelike structure or the filament coiling becomes U -shaped, V -arrangement or a plurality of U -shaped, the V -arrangement structure of formation side by side. When elastic material is the elasticity filament, the filament of two equal length of need. Elastic material is the elasticity filament, and has one during for the clip in the exposed core no. 1, exposed core no. 2 at least, and the clamp holder on the clip is connected to every filament.
