医療用具
Document Type and Number:
Japanese Patent JP4905647
Kind Code:
B2
Abstract:
In a medical apparatus (1), tubular insertion device (10A) and tubular insertion device having the medical apparatus (1), the medical apparatus (1) has a main body (2) regulated to rotate around an axis of the tubular insertion device (10A) and having a cylindrical body (3) provided in contact with the main body (2) to rotate integrally with the main body (2). A torque regulation mechanism (4) is provided to release the integral rotation in unison with the main body (2) so as to block a torque transmission to the tubular insertion device (10A) when a torque applied to the cylindrical body (3) is more than a predetermined value. The block of the transmission renders it incapable to further rotate the tubular insertion device (10A), whereby preventing a torsional buckling from being induced on the insertion device (10A), and enabling the operator to quickly perceive an excessive torque.
