20220249187 | ROBOTIC SURGICAL INSTRUMENTS WITH ROTARY SHAFT POWER TRANSMISSION - A robotic surgical tool includes a handle and an elongate shaft extendable through the handle and including an outer proximal tube and an inner spline rotatably received within the outer proximal tube. A first actuation system is housed within the handle and operable to rotate the inner spline relative to the outer proximal tube and thereby transfer torque to a proximal or distal end of the shaft. A second actuation system is housed within the handle and operable to drive the outer proximal tube and thereby advance or retract the elongate shaft in z-axis translation through the handle. | 2022-08-11 |
20220249188 | SURGICAL DRAPE HAVING AN EXTENDABLE SLEEVE FOR COVERING A SURGICAL INSTRUMENT AND METHODS OF MAKING AND USING SAME - A surgical drape assembly, including a surgical drape having an opening located on the surgical drape, an extendable sleeve assembly operatively connected to the surgical drape, wherein the extendable sleeve assembly is operatively connected to the opening, and a surgical instrument, wherein the surgical instrument is covered by the surgical drape and a portion of the surgical instrument is located within the extendable sleeve assembly when the extendable sleeve assembly is in an extended condition. | 2022-08-11 |
20220249189 | STERILIZATION PACKAGING METHOD FOR BODY-ATTACHABLE-TYPE BIOMETRIC MONITORING DEVICE - The present disclosure relates to a sterilization packaging method for a body-attachable biometric monitoring device. Provided is a sterilization packaging method for a body-attachable biometric monitoring device, the method in which a sterilization packaging process can be performed in a convenient and simple manner, further contamination which can occur during a sterilization process is prevented, damages due to moisture and the like after the packaging is complete are also prevented and thus complete sterilization packaging can be performed, in order to separately perform a sterilization packaging step in two steps, primary packaging is performed for a sterilizable state and then sterilization is performed, secondary packaging is performed to maintain airtightness for a primary packaged article which has been sterilized and thus penetration by an external contaminant and the like during the sterilization and packaging processes is prevented to prevent damages to a biometric monitoring device, a separate adsorbent is positioned outside the primary packaged article and then the secondary packaging is performed and thus functional degradation of the adsorbent during the sterilization process is prevented to enable inner packaging of the adsorbent in an excellent functional state, and a moisture removal function can be performed stably to enable a complete sterilization packaging. | 2022-08-11 |
20220249190 | SKULL PORTAL DEVICE FOR CRANIAL ACCESS - Apparatus for providing repeated cranial access comprises a hollow shaft sized to fit within a hole extending through a skull bone, the hollow shaft having a length of at least a thickness of the skull bone, a lip extending laterally form a first end of the hollow shaft for abutting the skull bone around the hole, and, a plug sized to fit into the hollow shaft, the plug extending at least the length of the hollow shaft and configured to be removably secured within the hollow shaft. | 2022-08-11 |
