  • Patent number: 11833770
    Abstract: The invention is generally related to a method for producing, in a relatively efficient and consistent manner, embedded or hybrid silicone hydrogel contact lenses, and also to unprocessed embedded or hybrid silicone hydrogel contact lenses, according to conventional cast-molding technologies. A method of the invention involve use of a polymeric non-reactive diluent in preparing a polymerizable composition for forming the silicone hydrogel material of the unprocessed embedded or hybrid silicone hydrogel contact lens, which is cast-molded with a lens mold. The unprocessed cast-molded embedded or hybrid silicone hydrogel contact lens has no or a minimal water-swelling degree, so that lens distortion or delamination during the hydration of the unprocessed embedded or hybrid silicone hydrogel contact lens.

  • Patent number: 11820170
    Abstract: Particular embodiments disclosed herein provide a retractable guard assembly coupled to a caster of a mobile equipment, comprising a housing and one or more guards at least partially disposed in the housing. The one or more guards are independently movably coupled to the housing. The retractable guard assembly further comprises corresponding one or more biasing elements coupled to the one or more guards and to the housing for biasing the one or more guards towards a fully deployed state. When the one or more guards are in the fully deployed state, contact between a fixed object and a portion of the one or more guards disposed outside the housing causes the one or more guards to transition into a retracted state, and when the contact is removed, the corresponding one or more biasing elements cause the one or more guards to transition into the fully deployed state.

  • Patent number: 11819274
    Abstract: A retina viewing system and method of using the same includes an ophthalmic microscope, a disposable lens attachment, and an electronic control unit (ECU). The microscope has an optical head and a set of internal focusing lenses, the latter providing the microscope with a variable working distance or focal length. The disposable lens attachment includes a resilient body with a proximal end connected to the optical head and a distal end connected to a high-power/high-diopter distal lens. The ECU executes instructions for viewing a retina or other intraocular anatomy of a patient eye. Execution of the instructions causes the ECU to automatically adjust the variable working distance or focal length of the microscope when viewing an image of the retina through the distal lens.

  • Patent number: 11806105
    Abstract: The present disclosure relates to high dexterity manipulation systems for microsurgical procedures. The surgical system includes a master apparatus controllably coupled to a slave apparatus configured to couple to a patient's head with a dual tripod structure having two pluralities of linear actuator links pivotally supporting a surgical tool shaft. The motions of the linear actuator links are controlled to provide at least 6 degrees of freedom for the surgical tool shaft. The slave apparatus may further include a redundant axis rotatable tool shaft, thus enabling 7 degrees of freedom for a surgical tool. The surgical system includes sensors enabling forces of interaction between the slave apparatus and its environment to be reflected back to the master apparatus. Forces imparted onto the master apparatus by an operator can be fed forward to control the slave apparatus and scaled down to reduce the forces on target tissues.
