Abstract: Provided is a position adjustment mechanism including: a case; a moving member including a first engaging part and a second engaging part; a lock member provided in the case so as to be movable between a lock position for regulating movement of the moving member in a first direction with respect to the case and a separate position for allowing relative movement of the moving member with respect to the case; and a long member. The lock member includes: a first engaged part engaging with the first engaging part in the first direction; and a second engaged part engaging with the second engaging part in the first direction. When the lock member is at the separate position, the lock member regulates separation of the moving member from the case by engagement of the first engaging part with the first engaged part in the first direction.

The two holding portions are configured to hold the target member from both sides. The joining portion connects two first ends of the two holding portions. The projecting portion protrudes from the joining portion toward an opening between two second ends of the two holding portions. The two second ends are opposite the two first ends of the two holding portions. The projecting portion has an end close to the opening, and the end protrudes further than at least one of the two second ends of the two holding portions in a direction where the projecting portion protrudes from the joining portion.

Abstract: A loading unit includes a shell assembly and a locking collar. The shell assembly has an annular ring that defines a locking slot and a proximal opening. The proximal opening configured to receive a distal end portion of the surgical instrument. The locking collar is rotatably disposed about the annular ring. The locking collar has a body including a flexible tab that has an inwardly extending lock. The locking collar is moveable about the annular ring between a locked and unlocked configuration. In the locked configuration, the lock passes through the locking slot and into the proximal opening of the annular ring. In the unlocked configuration, the body of the locking collar is rotated about the annular ring from the locked configuration to move the lock from within the proximal opening.

Abstract: In this cable linking device, when a lock member (16) is located in a restricting position for restricting the movement of a joint piece (13), an interposing member (17) can move to an interposing position between the lock member (16) and a holding member (11) and the interposing member (17) can be shifted between the interposing position and a movement-permitting position, and when the interposing member (17) has moved to the interposing position, the lock member (16) is restricted from moving to a restriction release position for releasing the restriction on the movement of the joint piece (13), therefore preventing a linking member from accidentally moving farther into the holding member.

Abstract: A locking retainer can be used with a slidable support that includes a two support member with respective sets of locking apertures, with the two support members slidably engaging each other to define a support profile. A strap can at least partly bound an internal area and can support a locking pin that extends into the internal area. The strap can have a locking configuration in which, with the slidable support disposed within the internal area, the locking pin extends into two of the locking apertures to lock the slidable support at a fixed length. A locking retainer can be installed by disposing the slidable support within the internal area, aligning two locking apertures of the slidable support, and applying lateral pressure to a side arm of the locking retainer to seat a locking pin in the aligned locking apertures.

Abstract: An improved coiled pin comprises a rectangular strip of metal coiled to form a substantially cylindrical pin having leading and trailing ends with a longitudinal edge on the pin exterior extending between the leading and trailing ends. The longitudinal edge has a transverse slit closer to the leading end than to the trailing end, thereby forming a flap having a width extending between the slit and the leading edge and having a free end aligned with the longitudinal edge. When the pin is fully installed and the flap is immediately adjacent the exit of the hole, the compression of the pin at the hole exit tends to expand the flap beyond such natural relaxation, approaching its neutral diameter, thereby providing a more pronounced mechanical stop against withdrawal.

Abstract: A retaining device to secure a socket to an anvil including an O-ring, an integral projection extending inwardly from the O-ring, and an insert secured at or near a far end of the integral projection. The insert may be made from a non-metallic high modulus material that can compress up to 50% of its original diameter without breaking. The insert may also include a socket wear indicator that consists, for example, of a raised ridge located within a recess on the side of the insert. The raised ridge, if crushed at the juxtaposition between the socket and the anvil, provide an early indication that the socket's drive aperture is worn and that the socket should be replaced.
