The medical system can include a dynamic pulley coupled to the pull wire, the dynamic pulley configured to collapse during rotation in a first direction and to expand during rotation in a second direction opposite the first direction. | 2021-07-01 |
20210196416 | SURGICAL INSTRUMENT - A surgical instrument according to an embodiment may include a first pulley and a second pulley. A shaft-side pulley, which is provided at a position closest to the shaft among a plurality of pulleys including the first pulley and the second pulley, has a groove width greater than groove widths of the other pulleys. | 2021-07-01 |
20210196417 | MASTER CONTROLLER ASSEMBLY FOR A ROBOTIC SURGERY SYSTEM AND METHOD - A master controller assembly for a robotic surgery system has a slave robot assembly having a slave surgical grip device providing a grip degree-of-freedom of motion lying in a predefined slave grip plane and a control unit. The master controller assembly has a portable hand-held master input tool operatively connected to the slave robot assembly. The master input tool has a master tool body having a manipulandum surface, to be hand-held by the surgeon's fingers. The master input tool is mechanically unconstrained from the slave robot assembly and has a grip command detector device having an operative portion. The operative portion is manually operable by radially directed pressure action exerted at an operative surface. A sensing assembly detects the radially directed pressure action so that the radially directed pressure action exerted at the operative surface determines a paired slave grip motion action of the surgical slave grip device. | 2021-07-01 |
20210196418 | Glove with Medicinal Pads and Differing Thickness Regions with Attached Sticker - A glove with thinner and thicker parts is disclosed. The thinner parts, in one version of the glove, cover all of a thumb and index finger and a distal phalanx of a middle and ring finger. The rest of the glove, in such an embodiment, is thicker. The thicker parts can include the palm and dorsal side of the hand. The thinner region palmar side of the distal phalanx of the middle and ring finger include, in embodiments of the disclosed technology, a pad with a peelable cover which reveals a local anesthetic and disinfectant. Such pads can further be used/attached with a version of the glove with only thinner material throughout. In this manner, one can grasp with greater dexterity with the thinner regions of the glove compared to the thicker regions and also use a disinfectant followed by an anesthetic. The glove further has, covering a minority of a dorsal side of the glove, a removable and reattachable dorsal peelable pad. | 2021-07-01 |
20210196419 | SYSTEMS, PRODUCTS AND METHODS FOR REDUCING GLOVE WASTE AND CONTAMINATION - A system for reducing glove waste comprising a glove dispensing box having an enclosure formed by a top portion, a bottom portion, a first rectangular side portion, a second rectangular side portion, a first rectangular end portion, and a second rectangular end portion, the top portion having an opening though which a glove can be pulled; a flexible sheet adhered to the glove dispensing box, wherein the flexible sheet is connected adjacent to the opening, the flexible sheet having a nonlinear, elongated slit dimensioned to permit passage of a single glove therethrough and to inhibit the passage of multiple gloves with a single manual pull; and an antimicrobial material disposed to inhibit microbial growth proximate to the slit. Also disclosed herein are accompanying methods and devices for reducing glove waste and contamination. | 2021-07-01 |
20210196420 | COUPLER TO TRANSFER MOTION TO SURGICAL INSTRUMENT FROM TELEOPERATED ACTUATOR - A sterile adapter for coupling a surgical instrument and a surgical instrument manipulator includes a bottom component and a coupling component. The bottom component includes a bottom component opening with a bottom lip having a locking mechanism. The coupling component is rotatably coupled to the bottom component. The coupling component includes an engagement feature that engages the surgical instrument manipulator. The coupling component further includes a locking mechanism opening that engages the locking mechanism when the engagement feature has not engaged the surgical instrument manipulator. The coupling component may include a retention tab that is aligned with the keyway to insert the coupling component into the bottom component opening and then misaligned with the keyway to retain the coupling component in the bottom component opening. A ramp may be provided on a leading edge of a pocket to facilitate engaging the coupling component with the surgical instrument manipulator. | 2021-07-01 |
20210196421 | SUPPLY LINE FOR A ROBOTIC ARM INSTRUMENT - A surgical robotic arm drape, the drape comprising: a sheet defining a cavity for housing a robotic arm; and a set of guiding elements attached to the sheet configured to retain a supply line threaded there through for use in a surgical procedure. | 2021-07-01 |
20210196422 | METHOD OF OPERATING A SURGICAL MICROSCOPE AND SURGICAL MICROSCOPE - A method of operating a surgical microscope includes detecting a position of a user, and setting a rotation angle of a camera about its main axis such that it is between a first angle and a second angle. The first angle is the rotation angle required to display a first straight object as a vertical line, and the second angle is the rotation angle required to display a second straight object as a horizontal line. The first object extends along a first line arranged in a vertical plane containing a line connecting the position of the user with the field of view. The first line is horizontal and traverses the field of view. The second object extends along a second line traversing the field of view. The second line is horizontal and perpendicular to the first line. | 2021-07-01 |
