A trocar including a trocar head attached to a cannula having a lumen with a distal opening, the cannula includes at least one elastomeric band positioned across said lumen.

A surgical device including a handle assembly, an elongated portion, an end effector, a drive shaft, and a wick is disclosed. The wick is disposed within an outer sleeve of the elongated portion and is made from a fibrous material. The wick is configured to transfer moisture from a first portion of the wick to a second portion of the wick.

A percuscopic access device is disclosed. The percuscopic access device has a hollow shaft with a proximal opening and a distal opening. The percuscopic access device also has one or more barrier ridges on the outside of the hollow shaft. The percuscopic access device also has one or more recesses on the inside of the hollow shaft and in communication with the distal opening. A cleaning obturator for use with the percuscopic access device is also disclosed. The cleaning obturator and percuscopic access device may be combined as a surgical apparatus. The cleaning obturator has a guide rod having a proximal end and a distal end. The cleaning obturator also has a plugging tip on the distal end. The cleaning obturator further has one or more swab guides proximal to the plugging tip.

An obturator sleeve for a trocar assembly and method of its use are disclosed for infiltrating a liquid medication such as a local anesthetic into the tissue walls of a port site wound during a laparoscopic procedure. The sleeve includes an internal flow passage for receiving the liquid medication. A diffusion polymer, located within the internal flow passage, first absorbs the liquid medication and then releases the liquid medication through a plurality of apertures in the sleeve. When port site wound tissue contacts the diffusion polymer, the diffusion polymer within the sleeve steadily releases the absorbed medication through the plurality of apertures. The obturator sleeve provides a means to adequately infiltrate medication into the tissues of the port site wound, and can be used to block the free nerve endings of the port site wound as well as nearby sensory and motor nerves.

A probe may be inserted into a body cavity to perform diagnostic intervention(s), therapeutic intervention(s), or both. The probe may be inserted through a body aperture that is naturally occurring or man-made, intentionally or by accident. The body aperture may form a seal encircling the probe so that insufflation retention material may be effectively retained in the body cavity so that an operator can perform the intervention(s). However, there may be leakage of the insufflation material. The insufflation retention device is configured to form an effective seal contactingly adjacent the body aperture and to provide a passageway for the introduction of the probe into the body cavity, such that a diagnostic intervention or therapeutic intervention or both may be performed.

The present disclosure relates to a trocar assembly with an integrated scope-cleaning structure. The trocar assembly may include a housing defining boundaries of a chamber with (a) a proximal opening configured to receive a distal end of a scope, and (b) a distal opening in fluid and mechanical communication with a trocar cannula. The trocar assembly may further include a cleaning element located at least partially between the proximal opening and the distal opening, where the cleaning element is movable with respect to the housing from at least a first setting where a first portion of the cleaning element may be in a first location and may form a first cleaning surface within the chamber, the first cleaning surface configured to remove debris from a distal end of the scope when the distal end of the scope contacts the first portion of the cleaning element.

The present disclosure relates to a housing for a laparoscopic trocar assembly with an integrated scope-cleaning structure. The housing may include a shell forming a wall portion of a chamber and a cleaning element forming at least a portion of an internal surface of the chamber, the cleaning element configured to remove debris from a distal end of a scope upon contact between the cleaning element and the distal end of the scope. The cleaning element may be movable with respect to the shell of the housing in response to an input force upon the shell that moves a portion of the shell and a portion of the cleaning element between a default state and a displaced state.

A surgical access system facilitates access to a surgical site within a patient's body through an incision in the body. Surgical access systems can have at least one retention member and a fluid transportation member configured to deliver fluid to a surgical site or to remove fluid from a surgical site. In some embodiments, a surgical access device irrigates a surgical site to reduce surgical site infections and removes fluid from the surgical site to increase a physician's visibility into the surgical site.

A diffuser for use with a wound retractor and configured to deliver gases includes an interface tube for connecting to a gases supply and a diffuser interface positioned at a proximal end of the interface tube, the diffuser interface configured for delivering gases received from the gases supply through the interface tube, and the diffuser interface comprising a diffusion mechanism configured to deliver gases in a diffusion direction. A wound retractor with an integrated diffuser is also disclosed. The wound retractor includes an upper ring, a lower ring, a sleeve extending between and connecting the upper ring to the lower ring, and an integrated diffuser interface having a gases inlet and a diffusion mechanism.

A surgical access device is configured to provide an access path via an elongated cannula so that a medical scope can be advanced into a surgical field within a patient. A housing of the surgical access device encloses a wipe assembly configured to clean a lens of the medical scope. An access passage having an axis can be defined within the housing, and the wipe assembly can be spaced from the access passage so that the medical scope is angled off of the access passage axis in order for the lens to engage the wipe assembly. Portions of the housing can define fulcrum surfaces about which the medical scope can be rotated in order to align the lens with the wipe assembly.
