A trocar with camera has a camera section. The camera section obtains a trocar image that includes an image of a white part on a surface of a puncture member by performing imaging when the puncture member of a trocar shaft is exposed at a deployed position. A white balance setting section for trocar image sets a white balance for the trocar image based on the image of the white part in the trocar image.

A device to access interior body regions includes a grippable handle, a cannula having a proximal end and a distal end, a retractable obturator disposed within the cannula and extending prominently of the distal end of the cannula, the retractable obturator being spring-biased away from the proximal end of the cannula and having an axially-extending lateral slot that is open at a distal end of the obturator and an arrow-headed blade received within the slot of the obturator, the blade being exposed only when the obturator is urged toward the proximal end of the cannula, the blade having a tip with an edge-to-edge angle in a range of 30 to 50. The cannula is selectively securable to a blade subassembly at a distal end of the grippable handle by a hub that can be decoupled from the device by pressing a cannula/hub release button of the blade subassembly.

The present disclosure provides a cannula assembly having a tube with an internal lumen, a proximal end portion and a distal end portion configured for insertion into a patient. The cannula assembly further includes a housing rotatably coupled to the tube between a closed position and one or more open positions. The housing contains an electronic component comprising an image transmission device, such as a camera, for collecting and receiving images of the surgical site. The housing is adapted to provide the image transmission device with a longitudinal or forward view when the housing is in the closed position and a transverse view (i.e., offset from the longitudinal axis) when the housing is in one of the open positions. The housing is disposed distal to the proximal end portion and proximal to the distal end portion of the tube to protect the image transmission device as the distal end portion creates an incision and/or passes through an existing incision in the patient.

A device and method is provided to gain access to interior body regions. The system includes a safety needle, a stylet assembly, a blade assembly, an obturator assembly, a cannula assembly, a handle assembly, an actuator assembly, and a lock assembly. The safety needle accesses an interior body region. The actuator assembly, lock assembly, and handle assembly interact to expose the blade assembly, after which the blade assembly expands the pathway created by the safety needle. The obturator then further expands the pathway and delivers the cannula assembly to the desired location. The safety needle, obturator assembly, blade assembly, handle assembly, actuator assembly, and lock assembly are removed, leaving the cannula assembly in place for future procedures.

An optical trocar system that includes an elongated obturator member having a first diameter. The elongated obturator member has a distal region, the distal region having a first diameter section having a diameter that is substantially equal to the first diameter of the elongated obturator member. The elongated obturator member has a second diameter section having a diameter that is less than the first diameter. The optical trocar system also includes an optical member attached to the distal region of the elongated obturator member such that the optical member encapsulates the second diameter section of the elongated obturator member and at least a portion of the first diameter section. A longitudinal bore through the elongated tubular obturator member is configured to receive an endoscope.

Adjacent tissue layers can be accessed using a catheter device with a distal tip having a conductive portion including a first cutting feature and one or more projections extending from the first cutting feature towards an outer diameter of the distal tip. Electrical energy can be supplied to the conductive portion of the device to cut tissue. A stent can be delivered to form a fluid communication between the adjacent tissue layers.

The surgical robotic access system provides access for robotic instruments and/or actuators including the introduction, operation and withdrawal of such robotic manipulators into a body cavity without permitting the escape of pressurized fluid or gas. The surgical robotic access system also provides a multi-faceted range of movement without touching or effecting pressure on the opening in the patient's body cavity.

Tools for brachytherapy providing an introducer sheath and an afterload catheter with particular marks and gratings that allow for a more precise and safe positioning of the tools and the load of the afterload catheter. In particular, the invention refers to a kit for use in brachytherapy.

Surgical devices having a plurality of outwardly-biased flexible fins capable of both inward convergence and outward flexion, provide for fluid retention and soft tissue retraction during surgical procedures. The outwardly-biased flexible fins also provide for soft tissue compression, decreasing the length of the lumen or passageway through which instruments pass, allowing for a wider range of movement of instruments and better access to the surgical site, especially in patients with greater amounts of fat tissue that would otherwise require longer lumen lengths in prior art endoscopic cannulas. An obturator assembly including a cannulated handle member with a cannulated shaft attached to said handle member, said shaft extending distally and terminating at a cannulated obturator tip. A hood structure found on such obturator tip may be used to secure one or more flexible fins prior to deployment.
