Robotic surgical tools, systems, and methods for preparing for and performing robotic surgery include a memory mounted on the tool. The memory can perform a number of functions when the tool is loaded on the tool manipulator: first, the memory can provide a signal verifying that the tool is compatible with that particular robotic system. Secondly, the tool memory may identify the tool-type to the robotic system so that the robotic system can reconfigure its programming. Thirdly, the memory of the tool may indicate tool-specific information, including measured calibration offsets indicating misalignment of the tool drive system, tool life data, or the like. This information may be stored in a read only memory (ROM), or in a nonvolatile memory which can be written to only a single time. The invention further provides improved engagement structures for coupling robotic surgical tools with manipulator structures.

This invention relates to a device (20) for inserting and positioning surgical instruments (10) in the body of a patient, with an outer cover (22), into which outer cover (22) at least a front part (11) of the surgical instrument (10) is insertable, and which outer cover (22) is removable for positioning the surgical instrument (10) at the point of application, the outer cover (22) being pulled away from the front part (11) of the surgical instrument (10) by means of a pulling device (21). In particular, the outer cover (22) is able to be pulled backwards over the front part (21) <sic. (11)> of the surgical instrument (10), and the surgical instrument (10), or respectively its front part, is able to be uncovered again, so that the function assigned to the surgical instrument (10) is able to be carried out unimpeded. The outer cover (22) can be returned to the starting position, in particular also by means of a return device. The outer cover (22) is preferably able to be controlled by means of the pulling device (21) using the handle (15) of the surgical instrument (10).

According to the present invention, a heat generating element to be current-carried is provided at a grasp portion on the tip side of a treatment portion, the patient's body tissue grasped between a pair of grasp portions is coagulated by heat of the heat generating element, and a metal scissors blade for cutting the patient's body tissue is provided on the rear side of the grasp portion in the treatment portion.

The present invention provides a surgical manipulator including a manipulator arm, an end-effector held by the robotic arm, surgical tools held by the end-effector and manipulator joints, particularly right-angle drive devices for transmitting rotational motion in one axis to a perpendicular axis.

A system and method for the temporary closure of a wound, especially an abdominal wound, to facilitate re-entry, final closure, and long term healing of the wound. An abdominal wound dressing and methods of use are described that enable the application of negative pressure to the wound site in a site healing promoting manner while also limiting the formation of adhesions that would prevent the removal of the dressing. The dressing comprises a layer of porous foam material (36) enclosed by sheets of elastomeric material (38) punctuated by a number of appropriately placed holes (34). Multiple layers of porous foam may also be used. A suction tube connector (16) is provided on an upper surface of a layer of foam (12) for connection to a negative pressure source. At least one layer of foam is enclosed in elastomeric material and is placed in direct contact with the tissue within the open wound. Fluids are drawn by negative pressure through the holes positioned in the elastomeric envelope, and through the foam. If multiple foam layers are employed, the lower layer(s) of foam are of a finer porosity while the upper layer of foam is coarse. An adhesive elastomeric sheet (14) covers the entire wound dressing and seals the edges to the skin surrounding the wound. An appropriate vacuum device is attached to the suction tube connector.

Introducers for introducing a surgical circular stapler into a patient. Various embodiments comprise cover members that are applied over a stapling head portion of the circular stapler. In some embodiments, the cover members are fabricated from a flexible stretchable material and have a bumper portion that protrudes distally beyond the distal face of the stapling head. The staples may be fired through the cover member and the balance of the cover member is withdrawn from the patient with the stapling head. Other cover embodiments are selectively movable from a position wherein the distal face of the stapling head is covered and other positions wherein the distal face of the stapling head is exposed.

A disposable shield designed to sheath a patient control device prevents contaminants from contacting or entering the device. The shield has a bi-directional opening through which the hand-operated device is inserted and removed from the shield. A removable sealing device is used to preserve the integrity of the shield when the sealing device is removed. The shield can therefore be changed each time the device is handled by a different person, minimizing the chances of cross-contamination. The shield also extends the life of the device by preventing biological contaminants from contacting the device.

A surgical system includes a surgical instrument, a battery assembly, and an aseptic bag. The battery assembly is configured to removably couple to the surgical instrument. The aseptic bag is sized and configured to encapsulate and seal the battery assembly within an inner chamber. The aseptic bag can cooperate with a fixed handle of the surgical instrument to encapsulate and seal the battery assembly within the aseptic bag. The aseptic bag may additionally or alternatively encapsulate a generator of the surgical system.

Devices, systems and methods for dynamically stabilizing the spine are provided. The devices include an expandable spacer having an undeployed configuration and a deployed configuration, wherein the spacer has axial and radial dimensions for positioning between the spinous processes of adjacent vertebrae. The systems include one or more spacers and a mechanical actuation means for delivering and deploying the spacer. The methods involve the implantation of one or more spacers within the interspinous space.

An isolation system for isolating a mobile computing device from an environment while retaining the functionality of the mobile computing device that includes at least one sheet and a sealable region. The sheet may include one or more layer to maintain functionality of the enclosed mobile computing device during use. The isolation system may include a sterilizable outer surface for rendering an enclosed mobile computing device usable in a surgical environment. The isolation system may include a pump and channels or valves to allow for fluid removal or addition to the interior of the isolation system. The sheet of the isolation system may further comprise microtextured inner layer so as to maintain functionality of the enclosed mobile computing device in an aqueous environment or in a soiled condition.

A method of preparing a surgical system for surgery includes inserting a battery assembly into an inner chamber of an aseptic bag through an open end of the aseptic bag, positioning a portion of a housing of a surgical instrument through the open end of the aseptic bag, coupling the battery assembly to the surgical instrument, and sealing the open end of the aseptic bag. The battery assembly is coupled to the surgical instrument while the battery assembly is within the inner chamber of the aseptic bag. When the open end of the aseptic bag is sealed the battery assembly is encapsulated within the inner chamber of the aseptic bag. A generator of the surgical system may additionally or alternatively be encapsulated similarly.
