  • Patent number: 10279489
    Abstract: The present invention provides a cutter knife, which even if made with only the metal parts, smoothness of sliding operation of the blade is not degraded in time, even without lubricating oil nor friction resistant coating, A slider of the cutter knife carries rolling member, which is made rolling contact with the outer surface of the cutter knife. Further, the slider has a protrusion which extends into the cutter knife body and is engaged into a hole formed on the blade. Since an external force applied onto the slider is received by the rolling member, the slider can be operated smoothly. Besides, the height of the protrusion is determined, such that the protrusion does not touch the inner surface of the cutter knife. Thus, the protrusion tip never interfere with the inner surface of the cutter knife, thereby the sliding operation of the slider would not be prevented.

  • Patent number: 10112312
    Abstract: A knife (1) with automatic blade retraction including a housing (2), a moveable actuating device (4), a rotatable blade unit (30), and a retraction element (34) which always applies a retraction force to the blade unit (30) in the direction of the retracted position. The rotatable blade unit (30) can be brought into engagement with the actuating device (4) and is moveable by means of the actuating device (4) from a position retracted in the housing (2) into a position extended from the housing (2). The blade unit (30) is also rotatable by the action of a cutting force in an extended position from an engagement position in which the blade unit (30) is in engagement with the actuating device (4) into a release position in which the blade unit (30) is not in engagement with the actuating device (4).

  • Patent number: 10076846
    Abstract: A tool includes a housing and a slidable blade assembly configured to move between a first, second and third positions. The blade assembly is configured to receive a removable blade, such that the blade is stored within the housing when the blade assembly is in the first position, a portion of the blade extends outwardly from the housing when the blade assembly is in the second position, and the blade is completely outside of the housing when the blade assembly is in the third position, facilitating removal from the blade assembly. The housing comprises a guide path associated with movement of the blade assembly. The guide path includes a first path portion associated with the blade assembly being in the first position or the second position, and a second path portion associated with the blade assembly being in the third position, the first and second path portions being noncontiguous.

  • Patent number: 9849027
    Abstract: An ocular implantation device comprises a housing having a longitudinal axis, a needle configured to receive an implant, and a plunger and a rod operatively coupled together. The plunger and the rod are disposed in the housing and are collectively, translationally moveable along the longitudinal axis of the housing. The rod is configured to be receivable within at least a portion of the needle to enable the rod to move the implant therethrough. An actuator is operatively engaged with the plunger such that movement of the actuator in a direction aligned with the longitudinal axis of the housing results in the translational movement of the plunger and the rod along the longitudinal axis of the housing in order to deliver the implant through the needle to a target site. An alternative embodiment of an ocular implantation device uses a retractable needle to deliver an implant.
