A tissue guard for insertion within an access device disposed within an operating cavity includes a base section defining open proximal and distal ends and a lumen extending therethrough between the open proximal end and the open distal end. The base section includes one or more openings in a side thereof in fluid communication with the lumen. The proximal end of the base section includes an evacuation ring in fluid communication with the lumen. A tissue cuff is configured to encapsulate the base section and is selectively moveable between a distal position for facilitating insertion of the tissue guard within an access device disposed within a tissue opening in an operating cavity and a proximal position wherein the tissue cuff encloses the one or more openings to form an evacuation channel between the one or more openings and the evacuation ring to facilitate fluid evacuation from the operating cavity.

An access device configured for inserting an intraosseous catheter into an interior portion of a bone is disclosed. In one embodiment, an intraosseous access device is disclosed, comprising a device body, a trocar needle included with the device body, and an intraosseous catheter removably disposed on the trocar needle. The device body is configured to enable a user of the access device to manually insert a distal tip of the trocar needle through a skin surface of a body of a patient to an external surface of a bone of the patient. An advancement mechanism is also disclosed and is configured to selectively and distally advance the trocar needle and intraosseous catheter a predetermined distance into an internal portion of the bone of the patient after the distal tip of the trocar needle has been inserted to the external surface of the bone.

A force sensor includes a substrate, a plurality of sensing elements, and a plate. The substrate includes a central aperture extending along a longitudinal axis of the substrate, and has a proximal surface, a distal surface, a first side surface, a second side surface, a top surface, and a bottom surface. A recess is defined in at least one of the distal surface, the first side surface, the second side surface, the top surface, or the bottom surface of the substrate. The plurality of sensing elements are disposed within the recess, and the plate is disposed over the recess and mounted to the substrate to hermetically seal the plurality of sensing elements within the substrate.

Trocar components and methods of use are described, wherein the trocar components are configured to provide access to intraperitoneal space via the rectouterine pouch to surgical tools, which optionally include one or more surgical robot members. The surgical tools are optionally 5 mm or more in diameter. In some embodiments, a cannula part has a lumen sized to provide to a plurality of the surgical tools simultaneous transvaginal access to the intraperitoneal space via the rectouterine pouch. In some embodiments, an incision sized to receive a distal aperture of the cannula is created, optionally using one or two dilators. The dilators are sized to create (optionally starting from a puncture by a needle 2 mm in diameter or less) an oblong aperture. In some embodiments, the oblong aperture is at least twice as wide across a long diameter as across a short diameter.

A safety needle is disclosed having a puncture needle with a needle lumen and a ground tip; a holding device that, during use, bears on the skin of a patient and holds the puncture needle; and a safety mechanism with a protection element that has a first, opened state and a second, closed state. When the holding device is taken away from the skin and/or when the holding device is moved with respect to the defined position, the safety mechanism automatically moves the protection element from a first position, in which the tip of the needle is exposed, to a second position, in which the tip of the needle is covered as the protection element at the same time transfers automatically from the first, opened state to the second, closed state.

A device for treating the vaginal canal by a laser beam. The device for treating the vaginal canal includes a retractor for the wall of the vaginal canal, associated with a scanning system for scanning the laser beam towards the wall by means of a pyramidal mirror for laser beam reflection.

An access port for sealing an opening of a natural orifice and supplying access to a body cavity through the natural orifice including: a sealing unit; an unobstructed single lumen cannula extending to the body cavity; a connector connecting the cannula to the sealing unit; an access opening through the sealing unit to the single lumen; a cap including a plurality of cap openings configured to seal between medical instruments inserted into the openings and the access opening.

Surgical tools and kits for performing methods include a grommet with cylindrical shaft, cutting tip, annular flange with suture retaining anchoring fixture; a grommet jig for extending between adjacent grommets and guiding a needle therebetween; a family of needles with single and double pointed ends, reinforced eyelets, stops to limit inadvertent exiting, double shaft construction with a longitudinal gap and sharpened, slicing ends, including a J shape embodiment; a bone anchor with ring to secure sutures about a patient's clavicle; a tissue dissector having radially extending cones to nick taut connecting tissues; a tissue rasp having a series of crisscrossing grooves along an end; a tissue mesher comprising one or more blocks having a matrix of holes for clamping a plurality of needles and a supporting framework; and a kit device and a method of surgically inserting an internal mesh brassiere under the breast skin.

A tissue guard includes a body defining an open proximal end, an open distal end, and a lumen extending through the body between the open proximal end and the open distal end. The tissue guard further includes a lip extending radially outwardly from the open proximal end of the body. The lip includes a plurality of spaced-apart cut-outs defined about the outer circumference of the lip to define a plurality of tabs of the lip. Each tab includes an outer edge segment. The body and the lip are monolithically formed as a single piece of material.

Systems and methods for preventing the seeding of cancerous cells during morcellation of a tissue specimen inside a patient's body and removal of the tissue specimen from inside the patient through a minimally-invasive body opening to outside the patient are provided. One system includes a cut-resistant tissue guard removably insertable into a containment bag. The tissue specimen is isolated and contained within the containment bag and the guard is configured to protect the containment bag and surrounding tissue from incidental contact with sharp instrumentation used during morcellation and extraction of the tissue specimen. The guard is adjustable for easy insertion and removal and configured to securely anchor to the body opening. Protection-focused and containment-based systems for tissue removal are provided that enable minimally invasive procedures to be performed safely and efficiently.
