A shaver arrangement for a surgical instrument includes an outer member and cutting blade at a distal end; the cutting blade being serrated to form teeth forming one or more tissue engaging cutting points being arranged to snag and/or cut tissue and being located inwardly from the outer member such that there are no tissue engaging cutting points capable in use of snagging and/or cutting tissue located on or outwards of an outer surface of the outer member. The shaver arrangement reduces the likelihood of collateral damage to surrounding non-target tissue. The shaver arrangement does not have tissue engagement cutting points on the outer profile of the cutting blade of the shaver arrangement, thereby reducing the likelihood of collateral damage when manoeuvring the surgical instrument as tissue is less likely to be inadvertently caught by the tissue cutting points.

An apparatus includes a modular colpotomy cup component and a modular shaft component. The modular colpotomy cup component includes a proximal base, an elongated sleeve, an expanding member, and a colpotomy cup. The proximal base is configured to couple to a distal end of a head of a robotic arm. The modular shaft component includes a coupling body and an elongated shaft. The coupling body is configured to couple to the head of the robotic arm such that the modular shaft component and the modular colpotomy cup component are attached to each other via the head of the robotic arm. The elongated shaft extends distally from the coupling body and is configured to be inserted through the opening of the proximal base such that the coupling body is configured to couple to the head of the robotic arm.

An endoscopic medical system can include an endoscopic end effector including three or more jaws. Each of the three or more jaws can respectively include a corresponding electromagnetic energy signal conductor. The end effector can also include two or more jaw linkages, an individual jaw linkage corresponding to a respective one of the jaws, such that at least two of the jaws are configured to move, independent of one another.

Instruments, systems and methods are provided for performing submucosal medical procedures in a desired area of the digestive tract using endoscopy. Instruments include a safe access needle injection instrument, a submucosal tunneling instrument, a submucosal dissection instrument, a mucosal resection device. Systems include a combination of one or more of such instruments with or without injectable agents. Embodiments of various methods for performing the procedures are also provided.

Embodiments of the invention provide hydrodissection and/or PCO prevention or reduction in a patient undergoing eye surgery. In one embodiment, the invention is a surgical device for cutting and excising a portion of tissue, for example in performing a lens capsulotomy. A capsulotomy tip is inserted into an eye through an incision in the surface of the eye. The capsulotomy tip includes a suction cup to provide suction to the lens capsule. Then suction is applied via the suction cup to secure the capsulotomy tip to the eye. In some embodiments, after the capsulotomy tip is secured to the lens capsule, a cutting element of the capsulotomy tip is used to cut a tissue of the eye. Fluid is pushed through the capsulotomy tip and the capsulotomy tip is removed from the eye. Moreover, disclosed is an intraocular lens (IOL) to be used in conjunction with the surgical device.

An unattended approach can increase the reproducibility and safety of the treatment as the chance of over/under treating of a certain area is significantly decreased. On the other hand, unattended treatment of uneven or rugged areas can be challenging in terms of maintaining proper distance or contact with the treated tissue, mostly on areas which tend to differ from patient to patient (e.g. facial area). Delivering energy via a system of active elements embedded in a flexible pad adhesively attached to the skin offers a possible solution. The unattended approach may include delivering of multiple energies to enhance a visual appearance.

The present disclosure relates to devices and methods for cosmetic treatment of a skin of a subject with RF energy. Examples of the present disclosure include movable electrodes and/or movable skin temperatures sensors.

An excision apparatus for removing cellular tissue includes a housing provided with a fixation portion. The fixation portion is configured to be arranged on cellular tissue such that a closed space is formed by the cellular tissue and an inner surface of the fixation portion. The fixation portion is configured to fixedly retain the cellular tissue near the inner surface by removal of air from the closed space via an air evacuating means. The apparatus further includes a cutting element moveably arranged in the housing such that the cutting element is movable between a retracted position and an extended position with respect to the fixation portion. The cutting element includes an electrode arranged at a distal end of the cutting element and is configured for cutting a section of cellular tissue retained by the fixation portion when the cutting element is in the extended position.

An ablation device including a body having a lumen for receiving a distal end of an endoscope, a cover portion extending from a side of the body, the cover portion defining a recess between the cover portion and the body, and an electrode platform having at least one electrode positioned thereon, the electrode platform movable between a covered position, where the at least one electrode is covered by the cover portion, and an exposed position, where the at least one electrode is at least partially exposed beyond the cover portion. At least one vacuum port is formed in the electrode platform.

An ablation cap including a body having a lumen for receiving a distal end of an endoscope, the body having a central axis extending therethrough, and at least one guide for receiving at least one lateral extension of an electrode platform, wherein at least a portion of the at least one guide extends at an angle relative to the central axis of the body.
