  • Publication number: 20230310017
    Abstract: A surgical tissue grasper includes a handle assembly having a trigger, an endoscopic assembly, and a jaw assembly. The endoscopic assembly includes an outer tube and a driver. The driver is movable within the outer tube and operatively coupled to the trigger. The jaw assembly includes a stem detachably coupled to the driver, and a pair of jaws extending distally from the stem such that actuation of the trigger transitions the pair of jaws between spaced apart and approximated configurations to enable clamping of tissue. Each jaw of the pair of jaws includes a gripping portion and an outer support. The gripping portion is configured to engage tissue. The outer support is disposed outward of the gripping portion and coupled to an end portion of the gripping portion to enable flexing of the gripping portion or the outer support when a clamping force applied to tissue exceeds a predetermined threshold.

  • Publication number: 20230270421
    Abstract: A specimen retrieval device for endoscopic procedures includes a sleeve, barbed sutures, guide members, and a contractible band that is supported about an open distal end of the sleeve. Each of the barbed sutures have an elongate body, a distal portion, a proximal portion, and barbs that extend proximally from the elongate body. The guide members are secured to an inner surface of the sleeve and slidably receive respective barbed sutures. A tissue specimen to be removed from a patient is placed within a cavity defined by the sleeve and within the confines of the barbed sutures. Proximal portions of the barbed threads can be independently or simultaneously pulled in a proximal direction to withdraw the tissue specimen and the sleeve from the body cavity.

  • Publication number: 20230181174
    Abstract: A specimen retrieval device for laparoscopic procedures includes a plurality of barbed threads, the barbed threads having an elongate body, a distal portion, a proximal portion, and barbs extending from the elongate body. The distal portions of the barbed threads are circumferentially affixed to a centering ring and a space is formed within a circumference of the barbed threads. A tissue specimen to be removed from a patient is placed within the space and the proximal portions of the barbed threads are pulled in a proximal direction to reduce the volume of the space within which the tissue specimen has been placed, so that the barbed threads come into contact with the tissue specimen, thereby securing the tissue specimen within the space. The specimen retrieval device may then be removed from the patient's body cavity.
