Abstract
The present disclosure relates to a delivery device. The delivery device including a handle assembly, the assembly including a handle and a connector coupled to the handle, the connector including a channel and an opening to the channel; and a shaft coupled to the handle, the shaft including a proximal end and a distal end, the distal end including threads, grooves intersecting the threads, and a depth stop. Other delivery devices, screws, and delivery device/screw combinations are also disclosed.
Claims3
A delivery device comprising:
- a handle assembly, the assembly including a handle and a connector coupled to the handle, the connector including a channel and an opening to the channel;
- and
- a shaft coupled to the handle, the shaft including a proximal end and a distal end, the distal end including threads, grooves intersecting the threads, and a depth stop.
An interference screw comprising:
- a proximal end and a distal end, the screw including threads extending in an open helical form from the proximal end to the distal end, a depth stop extending a partial length of the screw, and a plurality of runners extending longitudinally along an interior of the screw.
A delivery device and screw combination comprising:
- a delivery device comprising a handle assembly, the assembly including a handle and a connector coupled to the handle, the connector including a channel and an opening to the channel;
- and a shaft coupled to the handle, the shaft including a proximal end and a distal end, the distal end including threads, grooves intersecting the threads, and a depth stop;
- and
- an interference screw coupled to the delivery device comprising a proximal end and a distal end, the screw including threads extending in an open helical form from the proximal end to the distal end, a depth stop extending a partial length of the screw, and a plurality of runners extending longitudinally along an interior of the screw, the screw located on the distal end of the delivery device such that a proximal end of the depth stop of the screw engages the depth stop of the delivery device.
