A bone marrow access apparatus includes a bone penetrating member and a cap. The bone penetrating member includes a tubular insertion portion, and a head portion provided at a proximal end of the tubular insertion portion. A cross-sectional shape of the head portion is wider than a cross-sectional shape of the tubular insertion portion. A recess is provided in the head portion, and an internal channel is provided through the head portion and the tubular insertion portion. The cap accommodates the head portion of the bone penetrating member therein. The cap includes a lower wall which covers at least a part of a distal side of the head portion, and a projection which projects into the recess of the head portion.

A medical device to protect a body opening, such as a vagina. The medical device may include a lumen and anchoring structure(s) for securing the device in the body opening. In some embodiments, the medical device includes a sleeve, a proximal ring attached to a proximal end of the sleeve, and a distal ring attached to a distal end of the sleeve.

A surgical port includes a shell and a seal assembly. The shell has a housing and a cannula that extends from the housing. The housing has a sidewall defining a window therethrough. The seal assembly includes one or more seals. The seal assembly is selectively receivable into the housing through the window of the housing of the shell.

Described herein are devices for approximating targeted tissue by intertwining two or more sutures together. The sutures are attached to the targeted tissue and routed to a twister device. The twister device secures end portions of the sutures and twists them to intertwine the sutures. Controlling the number of twists provides control over the forces applied to the targeted tissue. In conjunction with visualization feedback, real-time adjustments can be made to achieved targeted results, such as elimination of mitral regurgitation when the disclosed methods and apparatus are applied to mitral valve repair.

An introducer system for use with a navigation probe. The introducer system has an introducer and a probe retainer configured to selectively connect to the introducer. The probe retainer includes a receiver configured to receive a navigation probe shaft and limit movement of the navigation probe shaft in the lateral direction. A first clamp and a second clamp are connected to the receiver with the receiver located between the first clamp and the second clamp. Each of the first clamp and the second clamp is selectively engageable with respective portions of the introducer sidewall to hold the receiver at a fixed location relative to the introducer. The receiver, the first clamp, and the second clamp are configured to provide a visual path through the probe retainer and into the introducer passage.

A guide device for TMJ arthroscopy including one or more pairs of arms pivotly connected at one end to a working cannula holder and defining a working cannula axis; and at the opposite end to at one or more arms via one or more pivot connections to form with the arm one or more adjustable parallelograms, an end of the arm is connected to an irrigation cannula holder defining an irrigation cannula axis, the irrigation cannula axis intersecting with the working cannula axis at an intersection, intersection and one or more of the pivot connections between connecting the arms are located at opposing vertices of one or more of the adjustable parallelograms.

A surgical system includes a surgical assist robot including a robot main body and a slave controller, and a console. The robot main body has an entry guide, an entry guide support device, and at least one manipulator having an end effector provided at a distal end. The entry guide includes an inner cylinder, an outer cylinder into which the inner cylinder is inserted in an insertion axial direction, and a guide advancing device that displaces the inner cylinder in the insertion axial direction with respect to the outer cylinder. While a position and a posture of the end effector that has advanced from the entry guide are maintained, the inner cylinder is caused to advance toward the end effector within a predetermined movable range along the insertion axial direction with respect to the outer cylinder.

Provided is an eyeball attachment tube that is temporarily attached to an outer membrane of an eyeball in ophthalmic surgery for communication between the inside and the outside of the eyeball such that the eyeball attachment tube is inhibited from becoming unstable when attached in a direction deviating from a direction perpendicular to the external surface of the eyeball.

An eyeball attachment tube includes: a tubular portion configured to be in a state of puncturing an outer membrane when the eyeball attachment tube is attached to the outer membrane; and a large diameter portion which is disposed on a proximal end side of the tubular portion. An end portion of the large diameter portion on the tubular portion side is formed as a plane inclined relative to a center axis of the tubular portion.

Example embodiments relate to robotic arm assemblies. Embodiments of the robotic arm assembly include a shoulder segment and upper arm segment having a motor drive portion. Embodiments also include a shoulder coupling joint assembly connecting the upper arm segment to the shoulder segment. Shoulder coupling joint assembly includes a distal shoulder joint subassembly connected to the upper arm segment. The distal shoulder joint subassembly includes a distal shoulder joint forming a first axis. The distal shoulder joint subassembly includes a shoulder planetary gear assembly. Embodiments include an elbow coupling joint assembly connecting the upper arm segment to the forearm segment. The elbow coupling joint assembly includes a proximal elbow joint subassembly connected to the upper arm segment. The proximal elbow joint subassembly includes a proximal elbow joint forming a second axis. The proximal elbow joint subassembly includes an elbow planetary gear assembly.

A tissue guard includes a body having a proximal end and a distal end and defining a lumen therethrough. The distal end has a long petal and a short petal disposed in substantial opposition relative to one another and the short petal is configured to move between a first position wherein the short petal is disposed within the lumen to facilitate insertion of the long petal within an incision and a second position wherein the short petal is extended relative to the lumen and in substantial opposition to the long petal to facilitate retention of the tissue guard within the incision.
