20150313672 | IDEAL VALUES FOR LASER PARAMETERS FOR CALCULI REMOVAL - A set of ideal values for laser parameters is provided for a laser system for the fragmentation and removal of calculi. Particularly, the ideal values for laser parameters increases the effectiveness of removing calculi by increasing the pulse width. This set of ideal values for laser parameters increases the effectiveness of calculi removal by decreasing retropulsion distance of calculi fragments and by breaking up the calculi into smaller fragments that can then be easily removed from the body without the use of baskets or graspers. | 2015-11-05 |
20150313673 | SHARPS CONTAINER - A sharps container for safe reception and storage of used pen needles, pen needle assemblies, syringe needles, syringe needle covers, and combinations thereof comprises a substantially non-porous housing which includes a means for receiving said pen needles, pen needle assemblies, syringe needles, syringe needle covers, and combinations thereof in an internal storage compartment sized to facilitate the safe storage of a plurality of used pen needles or syringe needles and optional needle covers. The internal storage compartment may include a material capable of absorbing and storing fluids which may incidentally be associated with the used pen needles or syringe needles. The means for receiving pen needles, pen needle assemblies, syringe needles, syringe needle covers, and combinations thereof is visually distinguished from the surrounding portions of the housing and conveys the pen needles, pen needle assemblies, syringe needles, syringe needle covers, and combinations thereof from the exterior of the container to the internal storage compartment. | 2015-11-05 |
20150313674 | BREAST BIOPSY LATERAL ARM SYSTEM - A breast biopsy lateral arm system includes a removable gun mount which attaches to a carriage that traverses along an X-axis defined by a lateral arm in order to position a biopsy needle relative to a patient. The carriage rides along the lateral arm on self-adjusting rollers which are loaded against the lateral arm by spring members. A cam-actuated carriage slide lock can be used to secure the carriage in a desired position relative to the lateral arm. A cam-actuated removable gun mount lock allows the gun mount to be quickly changed and offset orthogonally with respect to the X-axis. An X-axis stop can be used to establish a position to which the carriage can be returned with accuracy. | 2015-11-05 |
20150313675 | System and Device for A Fully Automated Approach to Facilitate Stellate Ganglion Block or Pulsed Radiofrequency Procedure for Treating PTSD - A system and method to facilitate a stellate ganglion block or a pulsed radiofrequency procedure to treat post-traumatic stress disorder. The method can be fully automated and guided by a computer or the process can be guided by the surgeon. A computer including a central processing unit (CPU) is connected to a body scanning device and an injection mechanism. The body scanning device is used to read images of a patient's body. The information collected from the images is transmitted to the CPU. A housing for the injection mechanism encloses syringes for delivery of an anesthetic and a clonidine mixture. After the anesthetic is injected into the patient's skin from a first syringe, the housing is relocated by a connecting arm and a second syringe moves a needle into contact with the patient's bone. An electric eye scans for blood before the clonidine mixture is injected by the second syringe. | 2015-11-05 |
20150313676 | WRISTED SURGICAL INSTRUMENT CAPABLE OF MULTIPLE FUNCTIONS, WITHOUT REQUIRING EXTRA INPUTS - The present invention is generally related to the art of surgical instruments for use in minimally invasive surgery and more specifically to robotic laparoscopic surgery. According to one aspect of the invention, this articulated instrument is capable of producing a wrist-like motion, i.e. the end effector generally has three degrees of freedom. Additionally, it also has another degree of freedom for actuation of the end effector. The end effector has a configurable set of arms which are capable of performing a first function in a first mode and a second function in a second mode. This end effector also has the capability to dynamically switch between two modes of different functions (e.g.: scissor and grasper). These actions of switching back and forth between the different modes (e.g.: scissor and grasper) can be described as extra actions. These extra actions are achieved without increasing the number of inputs. | 2015-11-05 |
20150313677 | REMOTE MANIPULATOR DEVICE - A system for operating a catheter having a distal end adapted to be navigated in the body, and a proximal end having a handle with a translatable control and a rotatable control for acting on the distal end of the device includes a support for receiving and engaging the handle of the catheter; a translation mechanism for advancing and retracting the support to advance and retract a catheter whose handle is received in the support; a rotation mechanism for rotating the support to rotate a catheter whose handle is received in the support; a translation operator for engaging the translatable control of a catheter whose handle is received in the support and operating the translatable control to act on the distal end of the device; and a rotation operator for engaging the rotatable control of a catheter whose handle is received in the support and operating the rotatable control to act on the distal end of the device. | 2015-11-05 |
20150313678 | SHEATH FOR SURGICAL INSTRUMENT - A method using a sheathed surgical apparatus includes equalizing a pressure differential between a surgical insufflation gas pressure and an initial pressure lower than the insufflation gas pressure. The insufflation gas pressure is external to a portion of a surgical apparatus upon which a sheath is disposed, and the initial pressure is within the surgical apparatus. The equalizing of the pressure differential occurs via permeation of insufflation gas through the sheath. | 2015-11-05 |
