Device and methods for use during arthroscopic surgery

摘要

The present disclosure relates to a method of use during arthroscopic surgery. The method includes inserting a cannulated needle into a joint area of the body, inserting a guidewire through the needle, removing the needle, and inserting an arthroscopy knife into the joint area via the use of the guidewire. An arthroscopy knife and another method of its use is also disclosed.

主权项

1. A method of use during arthroscopic surgery comprising:
inserting a cannulated needle into a joint area of the body; inserting a guidewire through the needle; and inserting an arthroscopy knife into the joint area via the use of the guidewire, the knife comprising a distal end including a blade and a guidewire component by which the knife is coupled to the guidewire, and wherein a distal tip of the blade is fixed relative to the guidewire component; touching the distal tip of the blade of the knife to the guidewire such that the blade and the guidewire create an angle greater than zero degrees therebetween; and wherein the guidewire component receives the guidewire and defines a longitudinal axis of the guidewire which is at an angle relative to and intersects a longitudinal axis of the knife at a point proximal to the distal tip of the blade and distal to a proximal end of the knife, the longitudinal axis of the knife extending from the distal tip of the blade to the proximal end of the knife when the knife is not coupled to the guidewire, such that the blade is biased against the guidewire when the knife is coupled to the guidewire and the distal tip of the blade is touched to the guidewire.
