摘要： A method for removing a stone from a patient comprising the steps of: providing a suction evacuation assembly which includes a sheath and one or more side arms; inserting and positioning a distal end of the sheath into a lumen or cavity of a patient's body containing a stones; connecting a tube to one of the side arms and to a collection bottle; connecting another tube to the collection bottle and a negative pressure system; visualizing the stone or foreign body using a scope inserted through the assembly; activating the negative pressure system in order to remove the stone from the cavity if the diameter of the stone is narrower than an inside diameter of the sheath and the side arm, or performing a lithotripsy on the stone to create fragments with a decreased diameter which allow the passage through the assembly; and collecting the stone in the collection bottle.

摘要： A suture guiding device comprising a tubular shaft having opposite ends which are distal and proximal relative to a person holding the device for use in a suturing procedure, the distal end of the shaft being adapted to be inserted into a patient during the procedure. A suture guide is mounted at the distal end of the shaft for rotation relative to the shaft about an axis extending endwise with respect to the shaft. The guide has a guide surface for guiding a suture needle. A hand-operable control device is mounted on the shaft generally adjacent its proximal end. The guide and the control device are connected whereby hand-operation of the control device effects rotation of the guide to selectively adjust the suture-guiding position of the guide surface.

摘要： An instrument comprising a substantially rigid guide tube having opposite open ends which are distal and proximal relative to a person using the instrument. The guide tube has a shank portion and a distal end portion extending generally laterally with respect to the shank portion. A handle is provided on the shank portion of the guide tube generally adjacent the proximal end of the guide tube. A stiff but flexible shaft inside the guide tube has a distal end part movable distally relative to the guide tube to extend through and beyond the open distal end of the guide tube. A suture thread holder is provided on the distal end part of the shaft. The shaft is manually movable relative to the guide tube to move the distal end part of the shaft and the suture thread holder from a retracted position to an extended position along a substantially straight path extending generally laterally at an angle of not substantially less than ninety degrees with respect to the shank portion of the guide tube.
