A surgical device that provides a suction force against a patient's body. The device includes a stem having a proximate end and a distal end, the stem disposed about a channel, a suction head extending from the stem and defining a suction chamber in fluid communication with the channel, the suction head having a contact surface, and an articulating joint disposed between the contact surface of the suction head and the distal end of the stem. The articulating joint may be an annular joint and a living hinge. The surgical device may also include a handle disposed about the channel directly or may be disposed about the stem which is disposed about the channel. The handle may include a plurality of ribs extending outward which form a profile matching a profile of a user's hand.

An aerosol generator is positioned adjacent to a patient as an attachment to a trocar. The trocar has an entry port for insufflation gas. Aerosol generated by a vibrating element is entrained in the insufflation gas and the mixture is delivered through the trocar. The aerosol may contain a medicament. The trocar may be a conventional trocar. Such trocars are typically used for a camera. The delivery of the aerosolized medicament can occur at the start of the procedure and be delivered in bolus. At the start of the procedure, the peritoneum is being inflated by means of the flow of insufflator gas. This gas flow will help to entrain the aerosolized medicament to the pneumoperitoneum regions. The surgeon can temporarily remove the camera from the trocar port to facilitate insertion and positioning of the aerosolizing unit.

An optically transparent actuator apparatus is provided that includes an optically transparent bi-stable member including an optically transparent liquid crystalline polymer layer. The bi-stable member is structured to move from a first state to a second state in response to a first stimulus and from the second state to the first state in response to a second stimulus. Also, a display apparatus includes a plate member and an actuator assembly coupled to the plate member. The actuator assembly includes a number of optically transparent liquid crystalline polymer layers, wherein each of the optically transparent liquid crystalline polymer layers is structured to move from a first state to a second state in response to a first stimulus.

Cannula devices, systems, and methods are provided for introducing one or more instruments into a patient's body to perform a procedure. In one example, the cannula device includes first and second housings defining a throughbore, and a plurality of elongate members extending distally from the housings, the elongate members cooperatively defining a passage axially aligned with the throughbore between proximal ends and distal tips of the elongate members. The first housing is moveable in an axial direction with respect to the second housing to cause the proximal ends of the elongate members to move outwardly to increase a size of the passage and, optionally, may taper when expanded. Optionally, one or more secondary devices, e.g., an obturator with a sharpened tip, or an obturator and tubular access device may be provided that may be inserted through the throughbore into the passage before expansion of the passage.

The present invention relates to an ultrasonic aerosolization platform that has a single access port (10) provided with a trocar (11) inserted into the surgical cavity through a single incision and provided with at least one internal channel (101) in which is positioned an ultrasonic aerosolizer (20) provided with a head (21) that houses a power piezoelectric transducer (214) and a resonating rod (22) that extends orthogonally from the head (21), provided with an internal channel (221) in communication with the internal channel (212) of the head (21) and a free end (222) with an atomization nozzle (30) with orifices (31); a high-frequency ultrasound generator (40) that provides an electrical signal to the power piezoelectric transducer (214), which converts said electrical signal into mechanical oscillations transmitted to the resonating rod (22) in the form of mechanical standing waves; and a processing unit (50) provided with an interface (60) for adjusting the excitation frequency of the transducer (214), adjusting the flow of the therapeutic substance, and adjusting the operating and actuation time of the electrode (not shown) arranged in the resonating rod (22).

A surgical access device sterilizes tissue at a surgical site and/or the air at the surgical site. The surgical access device may include a cannula including an elongated shaft having a fluid delivery channel defined therein, a fluid delivery port coupled to the cannula and in fluid communication with the fluid delivery channel, and a porous sleeve disposed around the elongated shaft and in fluid communication with the fluid delivery channel. The fluid delivery channel provides a pathway for fluid flow (e.g., an anti-infective agent) from the fluid delivery port into the porous sleeve. The surgical access device may include a cannula including an elongated shaft having an anti-infective agent disposed therein. The surgical access device may include an instrument housing secured to a cannula, and a light source (e.g., an air sanitizing light source) disposed within a cavity of the instrument housing.

Disclosed herein are sealing devices configured for improving sealing functionality with an engaged extension member of an apparatus. More specifically, disclosed herein are trocar sealing devices configured for improving insufflation gas containment in relation to trocars (and/or other related type of devices) that are used for enabling a surgical instrument such, for example, a laparoscope, to gain access to an abdominal cavity (or other body cavity). By providing for such improved insufflation gas containment, sealing devices as disclosed herein are particularly advantageous, desirable and useful in view of long-standing reasons for limiting insufflation gas leakage and in view of newly recognized reasons stemming from outbreak of COVID-19 disease for limiting insufflation gas leakage.

A surgical access device includes a seal assembly, an upper housing portion, a lower housing portion, and a tubular member. The seal assembly has an instrument seal and is coupled to the upper housing portion. A first valve is partially disposed in an upper chamber of the upper housing portion and a second valve is partially disposed in a lower chamber of the lower housing portion. A valve assembly extends from the upper housing portion and is in fluid communication with the upper chamber. A source of insufflation fluid is attachable to the valve assembly.

The present invention generally provides methods and devices for removing fluid from a surgical instrument. Surgical access devices and seal systems are generally provided having one or more valves or seal assemblies to create a closed system between the outside environment and the environment in which the surgical access device is being inserted. The devices of systems can also include a fluid remover in the form of a sorbent element, a scraper element, a wicking element, or any combination thereof that is configured to remove fluid from a working channel of the device or system and/or from a surgical instrument inserted therethrough.
