Abstract: A tool that allows a person to attach a fixture to a ceiling, and do the job on their own, quickly, safely, and without frustration. The tool includes a guiding rod that is selectively attached to the ceiling mounted electric junction box, a fixture support that is movable along the length of the guiding rod, and a lock that secures the fixture support at any of a number of desired positions along the length of the guiding rod. A first embodiment of the tool is used in pairs and includes a threaded cavity at the distal end of the guiding rod that is selectively attachable to one of the pair of holding screws extending down from the junction box. The second embodiment of the tool includes a threaded section on the outside of the distal end that is selectively attachable to a junction box crossbar that has a central threaded opening. The embodiment chosen by the installer depends on the fixture design and the preference of the installer.

Abstract: A device (10) for introducing and removing a laparoscopic needle (200) through an incision (301) in a wall (302) of a body cavity (300) wherein the device (10) comprises a rod unit (11) including an elongated rod member (20) having a proximal (21) and a distal (22) end segment disposed on the opposite ends of an interior chamber (34) provided with an elongated slot (33) dimensioned to receive a curved laparoscopic needle (200) and a handle member (40) for manipulating the position of the laparoscopic needle (200) within the body cavity (300). In one version of the preferred embodiment, the curved needle (200) is releasably engaged between the tubular proximal end segment (21″) and distal end (51) of the elongated slot (33′) of the rod member (20′).

Abstract: An acoustical ring and bell sound system 10 for use with a variety 101, 102, 103 of musical wind instruments 100; wherein, the sound system comprises an acoustical ring element 21 and an acoustical bell element 31 dimensioned to releasably engage the proximal 104 and distal 105 ends of the musical instrument 100 for producing air turbulence control in the interior of the instrument 100.

Abstract: A clarinet ligature and grasping ring device (10) for use with a mouthpiece/reed assembly (100) wherein the device (10) includes a ligature unit (11) having a reed clamp member (20) and an elongated spring member (40) operatively connected to a mouthpiece member (101) having a reed member (103); and, a grasping ring unit (50) operatively connected to the mouthpiece member (101) and having a pair of apertured post members (71) which operatively engage spaced portions of the elongated spring member (40) for operatively and moveably connecting the ligature unit (11) to the grasping ring unit (12).

Abstract: A clarinet ligature and grasping ring device (10) for use with a mouthpiece/reed assembly (100) wherein the device (10) includes a ligature unit (11) having a reed clamp member (20) and a pair of spring support members (30) operatively joined together in a surrounding relationship with the mouthpiece member (101) of the assembly (100) by an elongated spring member (40); and, a grasping ring unit (12) fixedly secured to the mouthpiece member (101) so that the mouthpiece member (101) may be removed from the clarinet barrel member (106) without disturbing the engagement between the ligature unit (11) with the mouthpiece (101).

Abstract: A gynecologic instrument or uterine mobilizer having a tube with one end attached to a journal pivotally mounted and maintained within a channel in the head of the instrument via a pin engaging a groove in the head. The head includes structure, such as an attachment or collar, for manipulating a desired place of a vaginal wall when the instrument is inserted in the vagina. In one embodiment, the structure includes a collar having a concave surface lying over a surface of the head that is substantially crescent-shaped. In another embodiment, the structure includes a substantially disc-shaped element. In one of two related embodiments, the substantially disc-shaped element may be provided with an indentation or notch in a peripheral surface.

Abstract: A gynecologic instrument or uterine mobilizer having a tube with one end fitted to a tube holder and another end attached to a journal pivotally mounted and maintained within a channel in the head of the instrument via a pin engaging a groove in the head. It is adapted to be disassembled by first releasing the tube from the tube holder and rotating the journal to which the tube is attached a prescribed degree to permit the pin to disengage the groove in the head to permit the tube to be removed from the head.

Abstract: A clarinet ligature and grasping ring device (10) for use with a mouthpiece/reed assembly (100) wherein the device (110) includes a ligature unit (11) having a reed clamp member (20) and a pair of spring support members (30) operatively joined together in a surrounding relationship with the mouthpiece member (101) of the assembly (100) by an elongated spring member (40); and, a grasping ring unit (12) fixedly secured to the mouthpiece member (101) may be removed from the clarinet barrel member (106) without disturbing the engagement between the ligature unit (11) with the mouthpiece (101).

Abstract: An apparatus for injection of dye or contrast medium into a uterine cavity. An elongated member having a first and a second end and an intermediate portion has a liquid impervious expandable tube disposed around it and is sealed on each end thereof to the exterior thereof. A first fluid passageway extends from one end of the elongated member to a barrier and another fluid passageway extends from the other end of the elongated member to the barrier. A first opening in the elongated member allows fluid communication between the first passageway and the inside of the balloon tube and a second opening in the elongated member provides fluid communication between the second fluid passageway and the inside of the balloon tube.

Abstract: A chorion biopsy instrument for sampling chorion tissue including a housing and first and second telescoping tubes with the first tube being closed at one end thereof and having an opening on one side near the closed end. The second outer tube has a cutting edge which slides along the exterior of the first tube. A mechanism is provided for moving the second tube with respect to the first tube between a first position wherein the second tube covers the opening in the first tube and a second position wherein said second tube does not cover the opening in the first tube. A syringe is fluidly connected to a first passageway through the first tube and a bottle of culture medium is fluidly connected to a second passageway leading through the housing, between the two tubes, with the opening in the first tube connecting the first passageway to the second passageway when the tubes are in the first relative position thereof.

Abstract: This invention relates to a gynecologic instrument comprising a stem, a uterine hook, said uterine hook being pivotally mounted adjacent one of its ends to an end of said stem for angular adjustment with respect to the stem, and control means connecting with said uterine hook and extending therefrom to a location adjacent the end of said stem that is remote from the end where said uterine hook is connected for controllably turning said hook about its connection with said stem. There is also disclosed a method of using this instrument.
