An access device for accessing an intervertebral disc having an outer shield comprising an access shield with a larger diameter (˜16-30 mm) that reaches from the skin down to the facet line, with an inner shield having a second smaller diameter (˜5-12 mm) extending past the access shield and reaches down to the disc level. This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, “ultra-MIS” techniques.

A surgical retractor assembly for providing surgical exposure. The surgical retractor assembly consists of two frame segments connected by adjustable ratchet mechanisms to form a retractor frame. The ratchet mechanisms can be attached to tissue retractor blades that provide exposure of the wound when expanded, without the requirement of a direct connection/attachment to an operating table or bed frame. The tissue retractor blades are attached in a manner that is adjustable and facilitates the ability of the overall surgical retractor assembly to be raised or lowered with respect to the patient. The retractor frame also allows attachments of additional retractor blades or other surgical retractor accessories for additional surgical exposure.

An assembly comprising a drive gear coupled to a shaft and a dial. The drive gear is configured to rotate along a first axis based on movement of the dial. The assembly includes a first linking member located along a second axis and configured to rotate about the second axis based on contact with the drive gear as the drive gear is rotated. The assembly includes a second linking member located along the second axis and configured to rotate about the second axis based on rotation of the drive gear and a coupling between the first linking member and the second linking member. The assembly includes a linking member selector configured to rotate about the first axis and for selecting at least a position corresponding to the first linking member that causes the coupling between the first linking member and the second linking member.

The pupil expander is used to expand a pupil in ophthalmic surgery and includes a ring portion forming a ring and an iris hooking portion provided to the ring portion. The ring portion includes a first ring portion formed in a shape curved radially inward and a second ring portion formed in a shape curved radially outward, the first ring portion and the second ring portion being arranged alternately along a circumferential direction of the ring portion. The first ring portion is provided with the iris hooking portion. The iris hooking portion is configured to be hooked on a pupillary margin of an iris in a manner such that the first ring portion and the second ring portion are arranged on a front surface side of the iris.

A sternal elevator apparatus is disclosed. The sternal elevator may include a panel, a support beam traversing the panel, and a post coupled to a proximal end of the panel. The apparatus may also include an indicator handle coupled to the sternal elevator, an actuator drive pivotably coupled to the indicator handle, and a housing movably coupled to the actuator drive. The sternal elevator apparatus may have an actuator drive incorporating a linear rack. The housing further may include a cylindrical gear where the cylindrical gear is engaged with the linear rack.

The present invention includes a system, kit and apparatus to aid in the realignment of one or more bones of a patient. The present invention provides a substantially rigid orthopedic stabilization scaffold for attachment of one or more external fixators for the realignment of one or more bones of a patient. The orthopedic stabilization scaffold includes a first anchorable frame and a second anchorable frame that are removably attachable to an operating table and connected adjustably by one or more crossbars.

A surgical instrument includes a first member including a groove. A second member includes an aperture and teeth configured to slidably engage the groove. A third member is positioned in the aperture and includes a passageway defining a first longitudinal axis and a flange. A fourth member is positioned in the passageway and includes a lip that engages the flange. The lip extends at an acute angle relative to a second longitudinal axis defined by the fourth member. A fifth member is rotatably disposed in the passageway and includes a first end surface that engages a second end surface of the fourth member defined by the lip. In a first configuration, the fourth member extends perpendicular to the first longitudinal axis. In a second configuration, the fourth member extends at an acute angle relative to the first longitudinal axis. Systems and methods are disclosed.

A retractor blade assembly includes an arm member, blade connector and a retractor blade having stem member provided at the top of the blade. The stem member includes a first pin member, provided at an upper portion of the stem member. The first pin member has at least one abutment extending outward from the stem member, a first groove provided below the first pin member, a second groove provided below the first groove, provided about the circumference of the stem member, a second pin member having at least one abutment extending from the second groove. The blade connector cooperatively engages the stem member permitting the retractor blade to operate in a rotatable mode and a locked mode.

A wound retractor clamp includes an annular clamp body including a periphery configured to surround a proximal end of a wound retractor, and one or more resilient members connected to the periphery of the clamp body. The one or more resilient members deflect radially outward upon engagement of the clamp body with the wound retractor. The one or more resilient members snap onto the wound retractor and secure the clamp body to the wound protector subsequent to the engagement of the clamp body with the wound protector.

An umbilical catheterization device that allows a physician to prepare an umbilical cord and apply appropriate retraction to widen vessels to introduce a catheter. The device comprises a base and a plurality of arms. The arms may include retraction devices or may be compatible with independent retraction devices, including but not limited to sutures. The retraction devices are attached to the umbilical cord, and used to provide retraction.
