A medical instrument effectively suppresses a situation in which the edge of a blade springs immediately after completion of incision, excision, or the like. The medical instrument (1) includes manipulation members (14) that are held by a user, elastic members (11) that are respectively secured on one end of the manipulation members, and intersect each other at one end thereof, and opening-closing members (15) that are respectively secured on the other end of the manipulation members (14), and intersect each other at a pivot (13), functional parts (15a) for implementing a gripping operation, a holding operation, a cutting operation, or the like being respectively provided at one end of the opening-closing members (15), the functional parts (15a) being opened and closed by adjusting a pressing force applied to the manipulation members (14), the opening-closing members (15), the manipulation members (14), and the elastic members (11) being configured so that the pressing force applied to the manipulation members (14) and an opening-closing amount of the functional parts (15a) have a linear proportional relationship during a period in which the functional parts (15a) are operated.

A turning mechanism of a temple with respect to a bracket capable of always keeping the resistance force relative to the turning of the temple T with respect to the bracket and of regulating the resistance force. The turning mechanism comprises a shaft supporting portion provided on the bracket and having a hollow hole section therein, a shaft portion provided on the temple and having a hollow hole section therein, and an expansion member, wherein the expansion member is press-fitted in the hollow hole section of the shaft portion in a state where the shaft portion is fitted in the shaft supporting portion to produce a friction force due to a pressing force of the expansion member, thereby applying a resistance force against the turning of the temple.

A bridge of rimless glasses is fixed to lenses in a state where it is prevented from being deformed or varied by deformation prevention members, and a fixing portion between the bridge and lenses is not deformed, and hence the fixation at the fixing portion is ensured, thereby enhancing durability. Superelastic metallic material can be directly used by the bridge as the rimless eyeglasses. The bridge of rimless glasses is formed of a superelastic metallic material, and the bridge is fixed to the lenses by way of deformation prevention members. The deformation prevention members have pad arms and fixing bolts fixed thereto. The bolts are inserted into holes bored in the lenses. The pad arms have fitting portions fitted in recesses defined in the lenses. The bridge further comprises lens pads for ensuring fixation to the lenses while bringing into contact with ends of the lenses, fixing bolts to be inserted in holes bored in the lenses, and pad arms fixed to the lens pads, wherein the lens pads and said fixing bolts are fixed to the deformation prevention members.
摘要:
A turning method and a turning mechanism in eyeglasses capable of turning a temple with respect to a bracket with a simplified mechanism without using joints or bolts. The turning mechanism comprises a bracket having a main trunk and a hook, and a temple being turnable with respect to the bracket, wherein the hook has a first part for supporting an end of the temple so that the temple is turned about the first part, and a second part for stopping turning of the temple. The turning mechanism can be made very light weight and dispense with additional parts such as bolts and nuts.
