Abstract
A removable attachment for selectively connecting coaxial medical instruments comprises a first instrument having a proximal end, a distal end and a lumen extending therethrough. The first instrument comprises an arm extending from a fulcrum located on the first instrument and a second instrument movably placed within the lumen of the first instrument, the second instrument comprising a hub at a proximal end thereof. The hub comprises a distal edge to engage a proximal end of the first instrument. The arm pivots around the fulcrum and is configured to selectively engage the hub to provide a removable locking connection between the first and second instruments.
Claims19
A removable attachment for selectively connecting coaxial medical instruments comprising:
- a first instrument having a proximal end, a distal end and a lumen extending therethrough, the first instrument comprising an arm extending from a fulcrum located on the first instrument;
- and
- a second instrument movably placed within the lumen of the first instrument, the second instrument comprising a hub at a proximal end thereof, the hub comprising a distal edge to engage a proximal end of the first instrument, wherein the arm pivots around the fulcrum and is configured to selectively engage the hub to provide a removable locking connection between the first and second instruments.
The removable attachment of claim 3, wherein the pin is received in a bore formed in a wall of the first instrument, an end of the bore preventing entry of the pin into the lumen.
A device for facilitating insertion of a flexible instrument into a living body, comprising:
- an elongated body extending longitudinally from a proximal end to a distal end, the body defining a lumen extending therethrough;
- and
- a gripping mechanism extending from a proximal end comprising a handle to a distal end comprising an abutting surface, the gripping mechanism pivotally mounted to the elongated body for movement between a gripping configuration in which the abutting surface engages a corresponding abutting surface of the flexible instrument inserted through the lumen and an open configuration in which the abutting surface is radially separated from the elongated body.
A device for facilitating insertion of a flexible instrument in a living body, comprising:
- a body portion extending from a proximal end to a distal end;
- a gripping mechanism comprising a first arm movable from an open configuration in which the first arm extends distally out of the body portion in a radially expanded configuration to a gripping configuration in which the first arm is partially retracted into the body portion;
- and
- a first abutting surface formed on a distal end of the gripping mechanism and configured to engage a proximal portion of a flexible instrument received within the body portion.
