WIDE HEMOSTASIS CLIP
A device for treating tissue includes a capsule extending longitudinally from a proximal end to a distal end and including a channel extending therethrough, the capsule releasably coupled to a proximal portion of the device and clip jaws, proximal ends of which are slidably received within the channel of the capsule so that the clip jaws are movable between an open configuration and a closed configuration. Clip jaws are configured so that a distance between the distal ends of the clip jaws in an open configuration is between 15 and 18 millimeters. Clip jaws further include barbs extending from a distal portion thereof.
MULTI-CAP REMOVING-AND-HOLDING INSTRUMENT FOR SPINAL SURGERIES
A multiple-cap-remover for removing and holding spinal-implant guide caps, including a chamber component and a plunger movable disposed within the chamber. The chamber component has a chamber wall extending to an open end, and a cap-retaining component extending radially inward from an inner surface of the chamber at or adjacent the distal end. The distal opening is sized and shaped to allow the guide caps to pass through the opening and into the chamber component. The chamber component is sized and shaped to receive, one at a time, and hold simultaneously, multiple caps removed from respective spinal-implant assemblies using the instrument. The instrument may further have a sliding component connected movably to a body and connected to the plunger such that, when moved distally, it moves the plunger to push the caps captured beyond the cap-retaining component and out of the chamber component via the opening.
TISSUE RESECTING DEVICE WITH DEFLECTABLE TIP
A tissue resecting device includes a housing having an outer shaft extending therefrom, the outer shaft including a tool portion disposed at a distal end thereof, the tool portion having a window defined therein. A rotatable inner shaft is disposed within the outer shaft and includes a cutting member disposed at the distal end thereof in concentric alignment with the tool portion and configured to rotate concomitantly with the inner shaft. The cutting member includes a series of slots defined therein configured to facilitate articulation of the cutting member and a blade disposed at a distal end thereof configured to cut tissue upon rotational engagement therewith. An actuator is configured to articulate the tool portion and the cutting member upon actuation thereof between a neutral position wherein the blade is aligned for radial cutting and articulated positions wherein the blade is aligned for varying degrees of axially-aligned cutting.
ADJUSTABLE LENGTH TROCAR
A trocar is provided for providing access to body cavities during minimally invasive surgeries. The trocar possesses an elongate body formed of an outer tube and an inner tube, both of which are threaded. Rotating the outer tube about the inner tube permits adjustment of the length of the elongate body of the trocar. A locking collar on the trocar is used to maintain the elongate body at the desired length.
SYSTEMS AND METHODS FOR INSERTING AN ELONGATE FLEXIBLE INSTRUMENT INTO AN ENVIRONMENT
Illustrative systems and methods for inserting an elongate flexible instrument into a target environment are described. An illustrative system includes a guide device positioned near an opening to the target environment and having a rotary mechanism and a motor configured to drive the rotary mechanism. The system further includes a sensor system associated with insertion of the elongate flexible instrument along an insertion axis and a processor communicatively coupled to the motor and the sensor system. The processor is configured to receive sensor data from the sensor system, evaluate the sensor data, and control, based on the evaluation, the motor to actuate the elongate flexible instrument along the insertion axis. In some examples, the processor controls the motor to vary a rate of rotation of the rotary mechanism based on a determined system status.
Minimally invasive surgical instruments with terminal steerable mechanism
The present invention provides a minimally invasive surgical instrument with a terminal steerable mechanism, comprising an intervention device, a control device and one or more wires. The strip-shaped intervention device sequentially includes a main section, a flexible section and an operation section from the top to the end. The control device includes a sphere with a preset rotational degree of freedom, and an operating lever connected to the sphere. Said one or more wires are extended along the main section of the intervention device. Here, the second ends of said at least one or more wires are connected to the flexible section or the operation section of the intervention device, and the first ends thereof are connected to at least a part of the control device.
MINIMALLY INVASIVE INTERVERTEBRAL ROD INSERTION
A system and method for the minimally invasive insertion of an intervertebral rod into the vertebrae of a subject, according to a preoperative surgical plan also defining positions for the insertion of rod clamping screws into the vertebrae. The rod shape for connecting the heads of the screws is calculated, and a path planning algorithm used to determine whether the distal end of the rod can be threaded through the screw heads by longitudinal and rotational manipulation of the proximal end of the rod. If so, instructions are provided for forming that rod shape and for the robotic insertion of the screw holes and the rod. If not, either or both of the screw positions and the rod shape are adjusted, to moderate the bends in the rods, until insertion becomes possible. The insertion can be performed robotically, or, if a navigation tracking system is added, manually.
SYSTEMS AND METHODS CONFIGURED TO INSERT AN IMPLANT IN AN ABDOMINAL CAVITY
An implantation system and methods of inserting an implant are disclosed. The method includes the step of making an incision in an abdominal wall with an instrument positioned within an abdominal cavity. The method further includes the steps of forming a pocket between a first surface of the abdominal wall and a second surface of the abdominal wall, such that the incision defines an opening into the pocket, inserting an implant through the opening and into the pocket, and closing the opening such that the implant is captured within the pocket.
PERCUTANEOUS ACCESS PATHWAY SYSTEM
An improved method and device are provided for forming and/or maintaining a percutaneous access pathway. The device generally comprises an access pathway. The provided assembly substantially reduces the possibility of injury while accessing and/or re-accessing a body space.
Minimally invasive bunionectomy procedure using chevron osteotomy guide
A chevron osteotomy guide for use in a minimally invasive bunionectomy procedure comprises an oblong base plate having a modified rectangular shape with two parallel longitudinal sides, and having a semi-circular proximal end and a chevron shaped distal end. The chevron shape is isosceles triangular in which a dorsal edge and a plantar edge intersect to form an apex angle that is less than 90 degrees and greater than 60 degrees. In the bunionectomy procedure, the chevron osteotomy guide is attached to the first metatarsal bone using two K wires or pins through proximal and distal apertures in the guide. The proximal aperture is surrounded by two concentric tubular projections which are orthogonal to the plane of the base plate. These projections consist of an inner tubular core, having a circumference that coincides with that of the proximal aperture, and an outer tubular haft, which serves as a handle by which the surgeon adjusts the position of the guide on the first metatarsal bone. Once the osteotomy guide is stabilized on the medial side of the first metatarsal bone, the surgeon uses a sagittal saw sequentially guided along the dorsal edge and then along the plantar edge of the chevron guide, so as complete osteotomies through the dorsal and plantar cortices of the first metatarsal bone. These osteotomies allow the metatarsal head to be translated and pivoted into a position that corrects the patient's bunion condition.
