Methods and devices are provided for accessing a body cavity. In one embodiment, a surgical access device is provided that includes a housing having at least one access or sealing port for receiving a surgical instrument, and a retractor removably coupled to the housing and having a working channel configured to extend into a body cavity. The housing can include releasably matable upper and lower portions, with the upper portion being configured to freely rotate 360° relative to the lower portion and to the retractor when the housing is mated thereto.

Apparatuses, systems, and methods for sternal locators for placement of an intraosseous device into the sternum of a human patient.

A surgical access assembly includes an elongated cannula member having a proximal end portion and a distal end portion, a balloon anchor coupled to the distal end portion of the elongated cannula member, a sleeve of the balloon anchor extending proximally along an outer surface of the elongated cannula member, a chamber defined between the sleeve of the balloon anchor and the outer surface of the elongated cannula member, and a first collar is coupled to the elongated cannula member. The first collar is slidable along the elongated cannula member and engageable with the sleeve of the balloon anchor.

A sleeve clamp has a body with a through bore for receiving a sleeve, and a clamping element. The clamping element includes a clamping edge and may be arranged at the body so as to be movable between two positions, i.e. a neutral position and a deflected position. In the neural position, the clamping edge protrudes laterally into a lumen which is occupied by the sleeve when the sleeve is received in the through bore. In the deflected position, the clamping element may be elastically deformed and the clamping edge does not protrude into the lumen which is occupied by the sleeve when the sleeve is received in the through bore.

A pad is provided having a body for providing a gas seal over a surgical site, a port extending between a first surface of the body and a second surface of the body and sized accept a surgical instrument, and a lumen situated along the body and having a first opening and a second opening, the second opening aligned with the surgical site for communicating a fluid flow to the surgical site.

A cannula for use in a terminable intraosseous device comprises a cannula body, and a penetrator-independent proximal bone penetration indicator (PBPI) associated with the body for positively indicating initial penetration into the proximal bone. In various embodiments, the PBPI comprises a roughened surface provided at a distal end of the cannula body to assist in increasing an amplitude of vibrations that are generated immediately upon contact with a proximal bone cortex during performance of an intraosseous injection, a resilient element fixed at one end which becomes plastically deformed, a visually indicative element which is exposed when the distance between the cannula body and penetrator is changed, or a frictionally engageable element. In some embodiments, a stopper prevents additional penetration into the proximal bone, and a reinforcing member inserted within a cannula body lumen reinforces a thin-walled portion of the cannula body.

A medical device includes an elongate member and a port. The elongate member defines a lumen extending from a first end portion of the elongate member to a second end portion of the elongate member. The elongate member defines a helical pathway configured to convey a fluid. The port defines a lumen. The lumen of the port being in fluid communication with the pathway.

A surgical port includes an end face with a channel extending through the end face. The channel has a cross section shaped to receive a surgical instrument cannula. A lateral wall extends around a perimeter of the end face. The lateral wall and end face enclose an open volume. A rim extends radially inward from the lateral wall and projects into the open volume. An apron portion extends radially outward from the lateral wall and in a direction axially away from the end face. Surgical systems may include surgical ports. Methods relate to using surgical ports.

Systems, devices, and methods for performing Lapidus bunionectomy procedures are disclosed. An example method includes inserting a plurality of metatarsal pins into the first metatarsal at a first predetermined spacing relative to the first tarsometatarsal (TMT) joint, excising the first TMT joint by cutting the bases of the first metatarsal and the first cuneiform proximate the first TMT joint, inserting a plurality of cuneiform pins into the first cuneiform at a second predetermined spacing relative to the first TMT joint, compressing the first TMT joint using a compressor block such that a cut face of the first metatarsal contacts a cut face of the first cuneiform, and fixing the first TMT joint using a bone plate and a plurality of bone screws. At least one of the plurality of bone screws may be a cross screw extending at an angle of less than 90 degrees relative to the bone plate and may anchor the resected first TMT joint to the second metatarsal or the second cuneiform to prevent recurrence of the bunion.

An endoscope and methods of use thereof are provided, which includes at least one multi-functional extending arm supporting a plurality of imaging, lighting and other sensory elements. The arms provide a mounting platform upon which cameras, lights and sensors may be mounted to generate multiple-angled images and video, arena-like lighting and other data for performing a minimally-invasive surgical (MIS) procedure. The arms may be inserted through a single portal in the endoscope and extended outward in multiple directions from the single portal once inserted into a body cavity. The endoscope may also include support arms which support the extending arms within the body cavity and a stabilization plate which anchors the endoscope to an external surface of the body. An endoscopic tool with optical, lighting and other sensors integrated into a functional end is also provided.
