The compression piston may cause the impacting element to apply controlled force on a broach adapter to create a precise opening for subsequently disposing a prosthesis in a patient. The tool allows forward or backward impacting for expanding the size or volume of the opening or for facilitating removal of the broach and tool from the opening. A force adjustment control of the tool allows a user to increase or decrease the impact force. A light source and hand grips improve ease of operation of the tool. | 2022-01-20 |
20220015775 | METHODS OF NAVIGATION AND TREATMENT WITHIN A VERTEBRAL BODY - System and methods for channeling a path into bone include a trocar having a proximal end, distal end and a central channel disposed along a central axis of the trocar. The trocar includes a distal opening at or near the distal end of the trocar. The system includes a curved cannula sized to be received in the central channel, and having a curved distal end configured to be extended laterally outward from the distal opening in a curved path extending away from the trocar. The curved cannula has a central passageway having a diameter configured allow a probe to be delivered through the central passageway to a location beyond the curved path. | 2022-01-20 |

20220015777 | SHAVER WITH BLOOD VESSEL AND NERVE MONITORING FEATURES - A surgical instrument for cutting a first tissue and detecting a second tissue includes a shaft, a cutting member, and a tissue monitor system. The shaft extends along a longitudinal axis and includes a shaft lumen and a shaft opening. The cutting member is disposed within the shaft lumen and configured to cyclically move from a first position to a second position relative to the shaft. The cutting member is further configured to cut a tissue portion of the first tissue for removal therefrom. The tissue monitor system is associated with at least one of the shaft or the cutting member configured to detect the second tissue distinct from the first tissue for selectively cutting and removing the first tissue relative to the second tissue. | 2022-01-20 |
20220015778 | SURGICAL GUIDE FOR USE IN LIGAMENT REPAIR PROCEDURES - Devices, systems, and methods are provided for ligament repair procedures, and can be used to establish a location and trajectory for forming a bone tunnel in bone. One exemplary embodiment of a surgical guide for using in a ligament repair procedure includes a guide arm and a carriage that can be selectively locked along the guide arm to define an angle of the bone tunnel. The guide arm also defines a location of a distal end of the bone tunnel. In some embodiments the carriage is configured to have a bullet side-loaded into it, and the bullet can be used to define a location of a proximal end of the bone tunnel. The present disclosure also provides for a gage that limits the distance a drill pin that drills the bone tunnel can travel. A variety of other, devices, systems, and methods are also provided. | 2022-01-20 |
