Needle and guidewire holder
View Patent ↗Device and method for puncturing blood vessels while using fluoroscopy. The disclosed device enables improved needle orientation control and avoids direct exposure of the clinician's hand to X-ray during the puncturing procedure.
1. A needle holder comprising:
an elongate stiff member having a proximal end, a distal end, and a longitudinal axis;
a connector coupled to the distal end of the elongate stiff member, wherein the connector is capable of connecting to a needle;
a guidewire holder coupled to the elongate stiff member proximally of the distal end, the guidewire holder comprising:
(a) a flexible locking element located proximally of the distal end of the elongate stiff member; and
(b) a sliding knob arranged to slide over the flexible locking element in a direction parallel to the longitudinal axis and force the flexible locking element in a radial direction; and
a lumen traversing the connector, the elongate stiff member, and the guidewire holder, wherein the lumen comprises an inner wall and an opening disposed proximally of the flexible locking element, wherein the lumen is configured to have a guidewire pass therethrough, whereupon sliding the sliding knob over the flexible locking element, the flexible locking element directly contacts and presses the guidewire against the inner wall and holds the guidewire in place.
2. The needle holder according to claim 1 , wherein the connector comprises a male luer connector.
3. The needle holder according to claim 1 , wherein the opening comprises a female luer connector.
4. The needle holder according to claim 1 , wherein the needle holder has a length of at least 12 cm.
5. The needle holder according to claim 1 , wherein the needle holder has a length of 20 cm to 25 cm.
6. The needle holder according to claim 1 further comprising a second opening in fluid communication with the lumen.
7. The needle holder according to claim 6 , wherein the second opening is located distal to the flexible locking element and proximal of the distal end of the elongate stiff member.
8. The needle holder according to claim 1 , wherein the elongate stiff member is constructed of a clear polymeric material.
9. The needle holder according to claim 1 , wherein the flexible locking element is located within a hole within the elongate stiff member.
