Surgical needle device
View Patent ↗Various surgical introducer needle and anchor systems are provided. The systems can include an introducer needle and a tissue support implant or sling device. The implant device can include one or more anchoring devices. The introducer needle device can include a handle assembly and a needle assembly. The needle assembly can include a generally hollow needle, and a wire traversable therein. The wire can include a distal tip adapted to selectively retract or withdraw from the engaged anchoring device upon deployment of the anchor and/or implant.
1. A surgical needle device, comprising:
a needle including a lumen, a proximal portion, and a wire disposed in and traversable along at least a portion of the lumen; and
a handle assembly including a depressible actuator and a body portion, the depressible actuator having an elongate portion, and integral angled portions, and the body portion having a longitudinal axis, a proximal portion, a distal portion, and a side surface, the distal portion having opposing side channels and a curved end portion, with the distal portion coupled to the proximal portion of the needle, wherein the depressible actuator is in operative communication with a portion of the wire such that the integral angled portions extend distally beyond the curved end portion away from the needle and the elongate portion traverses within the handle assembly such that the depressible actuator traverses generally linearly along the longitudinal axis within the opposing side channels and toward the proximal portion.
2. The device of claim 1 , wherein a distal portion of the needle receives an anchor device.
3. The device of claim 2 , wherein the anchor device includes one or more extending tines to facilitate soft tissue engagement.
4. The device of claim 1 , wherein a distal portion of the needle includes a barb guard to abutably receive an anchor device.
5. The device of claim 1 , wherein the distal portion of the needle includes a curved length.
6. A surgical implant system, comprising:
a sling implant having opposing end portions and a support portion, and at least one anchor provided at one of the opposing end portions;
an implant introducer tool including;
a needle having a generally straight length, a lumen, a distal portion, and a wire extending through and traversable along at least a portion of the lumen for selective engagement with the at least one anchor; and
a handle assembly having a body, opposing channels extending out from the body, and at least one depressible actuator integral with an elongate member and operatively connected with the wire, the body having a distal end portion, a proximal end portion, and a side portion, the distal end portion having a curved end surface, wherein the generally straight length of the needle extends out from the distal end portion of the body and the at least one depressible actuator angles out from the side portion, extends out distally past the curved end surface, and is retractable a distance back into the distal end portion of the body, with the elongate member housed and traversable generally linearly and longitudinally within the body of the handle assembly such that the at least one depressible actuator traverses within the opposing channels away from the distal end portion and toward the proximal end portion.
7. The system of claim 6 , wherein the at least one anchor includes one or more extending tines to facilitate soft tissue engagement.
8. The system of claim 7 , wherein the distal portion of the needle includes a barb guard to abutably receive the at least one anchor.
9. The system of claim 6 , wherein the at least one depressible actuator includes first and second actuators angling out from the distal end portion of the body at an angle less than ninety degrees relative to the generally straight length of the needle.
10. The system of claim 6 , wherein a portion of the needle includes a generally curved length.
11. The system of claim 6 , wherein the at least one anchor includes an anchor device provided at each of the opposing end portions of the sling implant.
12. The system of claim 6 , wherein the sling implant is constructed at least in part of a polymer mesh material.
13. The system of claim 6 , wherein the distal portion of the needle includes a barb guard having an angled barb surface, and the at least one anchor has an angled anchor surface that abuttably seats with the angled barb surface.
14. The system of claim 6 , wherein a distal tip of the wire extends through and out of the at least one anchor.
