Publication number: 20210244423Abstract: A surgical apparatus having a locking mechanism that receives a cutting burr and that may include a loading and running position. The locking mechanism may include a motor driven spindle that carries a locking pawl and a detent pawl that lock the cutting burr in place an prevent the cutting burr from inadvertently falling out of the surgical drill instrument when in its load position. A diamond-shaped portion of the cutting burr may be formed in a six-sided diamond configuration and a perpendicular back end surface. The end of the cutting burr may include another diamond-shaped portion formed in a six-sided diamond shape surface that mates with a complementary surface formed in the receiving end of the spindle of the motor/locking mechanism. In an aspect, the attachment of the cutting burr is such that the cutting burr has substantially zero axial movement and runs true in the running condition.Type: ApplicationFiled: April 26, 2021Publication date: August 12, 2021Inventors: Eddy H. del Rio, Duane Jeffrey Enck

Publication number: 20210244424Abstract: A universal drill guide system includes a universal drill guide, interchangeable drill tubes, and interchangeable drill bits. Each interchangeable drill tube corresponds to one of the interchangeable drill bits, and can be detachably coupled to the universal drill guide. A cannulated drill with K-wire retention features a drill bit with a retention mechanism that prevents axial advancement of a K-wire during drilling. A drill removal tool includes a drill remover that can be placed around a drill bit to remove it from bone after a hole is drilled, while leaving a K-wire in place in the bone. A bone screw driver with K-wire retention includes a shaft that can be passed over a K-wire, a distal end for attachment to a cannulated bone screw, and a K-wire retention module for preventing advancement of the K-wire as the screw driver drives the cannulated bone screw into bone.Type: ApplicationFiled: February 1, 2021Publication date: August 12, 2021Applicants: Aesculap Implant Systems, LLC, Aesculap AGInventors: PETR SUCHOMEL, RALPH KOTHE, TAMARA LEDER, ERNIE CORRAO, SCOTT LARSEN, KEHUI CHEN, CHRISTOPHER SCHWARTZ, NICOLE SROKA, RON LITKE

Publication number: 20210244426Abstract: An insertion tool facilitating assembly of a surgical instrument includes a housing defining a distal end portion, a proximal end portion, and a central lumen. The central lumen extends therethrough the housing between a distal opening and a proximal opening, and defines a proximal portion and a distal portion. The central lumen is configured to receive a portion of a pin within the distal portion thereof. The insertion tool further includes retention channel defined about the housing at the distal end portion thereof. The retention channel is in communication with the central lumen. A D-ring is at least partially seated within the retention channel and extends into the distal portion of the central lumen to retain the pin therein by applying a compressive force to the pin. A plunger is configured to slide through the central lumen to deploy the pin distally from the distal opening of the central lumen.Type: ApplicationFiled: February 10, 2020Publication date: August 12, 2021Inventor: Amir Roomi

Publication number: 20210244427Abstract: According to the present disclosure, provided is a surgical instrument in which an actual motion of bending an end tool or performing a surgical treatment intuitively matches a motion of a manipulation portion corresponding thereto. In detail, to this end, provided are an end tool having various degrees of freedom, a manipulation portion having a structure to enable intuitive manipulation of a motion of the end tool, and a driving force transmission portion for transmitting a driving force of the manipulation portion to the end tool so that the end tool operates as manipulated by the manipulation portion.Type: ApplicationFiled: October 31, 2019Publication date: August 12, 2021Inventors: Jung Joo LEE, Hee Jin KIM, Dong Kyu JANG

Publication number: 20210244428Abstract: A surgical instrument for use with a robotic surgical system includes a knife blade configured to cut tissue and a knife tube coupled to the knife blade and configured to translate to move the knife blade for cutting tissue. The surgical instrument also includes a gearbox assembly coupleable to a robotic surgical system and configured to translate the knife tube to move the knife blade for cutting tissue and a knife blade lock operably coupled to the gearbox assembly. The knife blade lock is movable from a locked position wherein the knife blade lock prevents translation of the knife tube to an unlocked position in response to coupling of the gearbox assembly to the robotic surgical system wherein the knife tube is permitted to translate to move the knife blade for cutting tissue.Type: ApplicationFiled: February 10, 2020Publication date: August 12, 2021Inventor: Zachary S. Heiliger
