Abstract
A surgical device for arthroscopy includes an insertion arm having a folded contact end, a handle connected to a connection end of the insertion arm, opposite to the folded contact end, and extending transversely to the insertion arm, and a retrieval element connected to the insertion arm and mobile along the insertion arm between a retracted position and an extracted position in which it intercepts a leading end of a suture thread at the folded contact end, and mobile between the extracted position and the retracted position in which it holds the leading end. The retrieval element is a basket made of flexible material defining a containment volume for receiving said leading end of the suture thread. The containment volume is configured to expand in the transition between the retracted position and the extracted position and to shrink in the transition between the extracted position and the retracted position.
Core Innovation
The invention relates to a surgical device for arthroscopy for PCL reconstruction, including an insertion arm with a folded contact end configured to abut the surgical device against a patient's bone. The insertion arm is connected to a handle that extends transversely to the insertion arm and provides a connection end for the insertion arm opposite the folded contact end.
The device includes a retrieval element connected to the insertion arm and configured to be mobile along the insertion arm between a retracted position and an extracted position. In the extracted position, the retrieval element intercepts a leading end of a suture thread at the folded contact end, and in the retracted position it holds the leading end.
The retrieval element is a basket made of flexible material defining a containment volume suitable for receiving the leading end of the suture thread. The basket containment volume expands in the transition between the retracted position and the extracted position and shrinks in the transition between the extracted position and the retracted position.
A containment channel guides and protects the basket, including an outlet section and an inlet section, and the device includes a switch or slider and optional spring to move the basket between non-operational, semi-operational, and operational configurations.
Claims Coverage
The independent claim covers an arthroscopy surgical device with four inventive features. It combines a folded contact end for bone abutment with a transverse handle and a mobile basket-type retrieval element that intercepts and then holds a suture thread leading end, with a containment volume that expands and shrinks across movement between retracted and extracted positions.
Folded contact end abutting the patient's bone
An insertion arm having a folded contact end configured to abut the surgical device against a patient's bone.
Transverse handle connected to the insertion arm
A handle connected to a connection end of the insertion arm, opposite to said folded contact end, and extending transversely to said insertion arm.
Mobile retrieval element intercepting and holding a suture thread leading end
A retrieval element connected to said insertion arm and configured to be mobile along said insertion arm between a retracted position and an extracted position in which the retrieval element intercepts a leading end of a suture thread at said folded contact end, and mobile between said extracted position and said retracted position in which the retrieval element holds said leading end.
Flexible-material basket with expandable and shrinkable containment volume
The retrieval element is a basket made of flexible material defining a containment volume suitable for receiving said leading end of the suture thread, said containment volume being configured to expand in the transition between the retracted position and the extracted position and to shrink in the transition between the extracted position and the retracted position.
Overall, the claim coverage centers on a folded contact end for bone abutment and a mobile basket-type retrieval element that intercepts and retains the suture thread leading end, with an expandable and shrinkable containment volume.
Stated Advantages
Improves precision/safety.
Reduces instrument exchanges.
Reduces operative time by enabling grasping without additional tools.
Documented Applications
Used for PCL reconstruction in arthroscopy, including embodiments discussed in connection with tibial-tunnel outlet interception and pull-through with a suture thread.
