A surgical tool for use with a drill bit to prevent skiving at an implant insertion site on a bone includes a cannulated sleeve having a distal end defining a burr surface. The distal end may be detachable from a body of the cannulated sleeve. The tool may be used with more than one distal end, each of the distal ends defining a burr surface having a different cutting surface from the others. The tool may form a system that includes the drill bit.

Meniscal repair devices, systems, and methods are provided.

A cannula device (1) comprises a housing (11), a cannula (10) arranged on the housing (11), and a puncture device (17) which, in a use state, is arranged on the housing (11) and comprises a puncture trocar (18) received in the cannula (10). The puncture trocar (18) is displaceable with respect to the cannula (10) and comprises a trocar tip (180) which, by displacing the puncture trocar (18) with respect to the cannula (10) in a puncturing direction (P), is movable to protrude from the cannula (10) in said puncturing direction (P), wherein the puncture device (17) is removable from the housing (11) in a removal direction (A) opposite the puncturing direction (P). A protection element (15) is received in the housing (11) and comprises a connection portion (150) arranged on the puncture trocar (18) and at least one shielding leg (152, 153) pivotably connected to the connection portion (150), wherein the puncture trocar (18) is configured to carry the protection element (15) along when the puncture trocar (18) is removed from the housing (11) in said removal direction (A), the at least one shielding leg (152, 153) being configured to be pivotably moved with respect to the connection portion (150) to approach the trocar tip (180) when the protection element (15) is carried along by the puncture trocar (18).

A method of using a surgical modular robotic assembly including an interchangeable motor pack, a hand-held surgical instrument, and a robotic surgical instrument is disclosed. The method includes releasably attaching an interface portion of the interchangeable motor pack to the hand-held surgical instrument, causing the interchangeable motor pack to drive a first surgical tool of the hand-held surgical instrument, stopping the interchangeable motor pack from driving the first surgical tool, disconnecting the interface portion from the hand-held surgical instrument, and releasably attaching the interface portion of the interchangeable motor pack to the robotic surgical instrument.

Selectively lockable holding arrangements for a surgical access assembly are disclosed. One holding arrangement includes a body portion, an engagement barrel and a retaining member configured as a hook at a distal end of the body portion. The engagement barrel is position on a proximal end of the body portion and is configured to be selectively rotated about the body portion when operatively connected to a surgical holding arrangement. A rotation brake is mounted on the body section. The rotation brake is selectively operable to lock the engagement barrel against rotation.

An aiming arm system comprises an aiming arm and a guide sleeve. The aiming arm has 1) a body and a guide hole that extends through the body along a hole axis, and 2) a retention element supported relative to the body. The aiming arm is configured to be positioned such that the hole axis is aligned with a target location of an anatomical implant. The guide sleeve extends along a linear direction, and is sized to be inserted through the guide hole in the linear direction. Relative rotation between the guide sleeve and the retention element transitions the aiming arm system between an unlocked configuration whereby the guide sleeve is insertable through the guide hole, and a locked configuration whereby the retention element applies a retention force to the guide sleeve that substantially prevents the guide sleeve from moving further along the linear direction.

A trocar for peritoneal dialysis is disclosed herein. An example trocar includes a conduit having two or more parallel lumens and a head connected to a first end of the conduit. The head includes two (or more) parallel lumens that are aligned respectively with the parallel conduit lumens and includes at least one of a gasket or a seal for each lumen. The trocar also includes a coupler connected to the head. The coupler includes two (or more) parallel lumens that are aligned respectively with the parallel lumens of the head. The coupler includes a coupling mechanism for each lumen for securing surgical tools in place after insertion into a patient. The trocar may also include an obturator having a shaft that is removably inserted through the coupler, head, and conduit to protrude from a second end of the conduit.

Surgical visualization systems and related methods are disclosed herein, e.g., for providing visualization during surgical procedures. Systems and methods herein can be used in a wide range of surgical procedures, including spinal surgeries such as minimally-invasive fusion or discectomy procedures. Systems and methods herein can include various features for enhancing end user experience, improving clinical outcomes, or reducing the invasiveness of a surgery. Exemplary features can include access port integration, hands-free operation, active and/or passive lens cleaning, adjustable camera depth, and many others.

Exemplary systems and methods encompass suture knot tools and suture knot tools pre-loaded with sutures for use in tendon repair and other surgical procedures. Related methods may include forming a nail knot between a suture and a tissue of a patient during a surgical procedure by drawing tissue into a port sleeve of an arthroscopic system, moving the port sleeve relative to a free end portion of the tissue and a nail knot cinch of a suture, to allow the nail knot cinch of the suture to contact the free end portion of the tissue; and tightening the nail knot cinch of the suture about the free end portion of the tissue, so as to form the nail knot with the suture and the tissue.

A puncture adapter of an embodiment holds a puncture needle and is attached to an ultrasonic probe having an ultrasonic probe group. The puncture adapter has a puncture bracket that can be fixed to the ultrasonic probe and a puncture needle guide that is attached to the puncture bracket. The puncture bracket is not fixed to the ultrasonic probe when the puncture needle guide is not attached. The puncture bracket is fixed to the ultrasonic probe when the puncture needle guide is attached.
