Devices and Methods for Continuous Surgical Suturing
A surgical suture module for a machine constructed and configured for automatic, continuous suturing for reduced or minimized scarring and reduced suturing time. A surgical suture module for continuous, subcuticular suturing. The module includes a generally circular needle with a needle shaft; a supply of thread; a thread guide; a hook with a hook shank, a holding arm mechanism; and a housing. The needle, rotationally movable between a first position and a second position, is configured to introduce the thread into a tissue. The hook is operable for hooking and lifting the thread in coordination with the needle and the holding arm mechanism is operable for pushing and catching the thread in automatic coordination with the hook. The needle, the hook, and the holding arm mechanism are held in position by the housing and the housing operable to attach to a power supply that provides power to the module.
Suturing devices for heart valve surgery
Disclosed are devices and methods for delivering several sutures accurately and simultaneously around the perimeter of an annular prosthetic device (prosthetic heart valve, annuloplasty ring, etc.) to secure the prosthetic device within a native heart valve region. Devices can comprise a proximal handle portion including an actuator and a distal suturing portion including several curved and straight needles arrayed around the shaft axis. The straight needles and the curved needles are configured to simultaneously guide a plurality of sutures through the native tissue and through the annular prosthetic device. The actuator can cause the straight needles to move axially relative to the curved needles and can also cause the curved needles to rotate, such that the motions are coordinated to simultaneously place all the sutures.
THORACIC IMAGING, DISTANCE MEASURING, SURGICAL AWARENESS, AND NOTIFICATION SYSTEM AND METHOD
A method for enhanced surgical navigation, and a system performing the method and displaying graphical user interfaces associated with the method. A 3D spatial map of a surgical site is generated using a 3D endoscope including a camera source and an IR scan source. The method includes detecting a needle tip protruding from an anatomy and determining a needle protrusion distance corresponding to a distance between the needle tip and a surface of the anatomy using the 3D spatial map. A position of a surgical tool in the 3D spatial map is detected and a determination is made by the system indicative of whether the needle protrusion distance is sufficient for grasping by the surgical tool. A warning is generated when it is determined that the needle protrusion distance is not sufficient for grasping by the surgical tool.
SYSTEMS AND METHODS FOR AUTONOMOUS SUTURING
The present disclosure provides a system for enabling autonomous or semi-autonomous surgical operations. The system comprises: one or more processors that are individually or collectively configured to: process an image data stream comprising one or more images of a surgical site; fit a parametric model to a tissue surface identified in the one or more images; determine a direction for aligning a tool based in part on the parametric model; determine an optimal path for automatically moving the tool to perform a surgical procedure at the surgical site; and generate one or more control signals for controlling i) a movement of the tool based on the optimal path and ii) a tension force applied to the tissue by the tool during the surgical procedure.
Suturing device and methods of use thereof
A suturing device includes a hollow needle. The hollow needle has a length extending between a proximal end and a distal end and defining a lumen having an inner diameter. The suturing device further includes a length of surgical suture having a leading end and a trailing end and an outer diameter smaller than the inner diameter of the lumen. At least a portion of the surgical suture is located within the lumen of the hollow needle. A surgical kit including the suturing device and methods of using the suturing device of the present invention are also disclosed.
Suturing device and clamp for use with same
A suturing device comprising an elongated member including a cavity formed in a surface thereof, a needle passage, and a vacuum port. When the elongated member is inserted into a body including tissue and a vacuum is applied to the cavity, the tissue is captured by the cavity. A needle pusher is operable to move a needle having a sutured attached thereto through the tissue until a first end of the needle is captured by a needle capturing assembly. A clamp coupled to the elongated member is used to extract the needle from the needle capturing assembly and reposition the needle with suture attached to be re-engaged by the needle pusher. The cavity may include a plurality of cavity portions for capturing multiple contiguous portions of the tissue such that a single pass of the needle and the suture results in the suturing of the multiple portions of the tissue.
Surgical dissectors configured to apply mechanical and electrical energy
A surgical instrument comprising an end effector is disclosed. The end effector comprises a surgical dissector. The surgical dissector can apply mechanical and/or electrosurgical energy to treated tissue.
ROTARY STITCHING DEVICE
A stitching device includes an end effector having first and second jaw members and first and second pins, a stationary cam, and a rotary cam. The first pin is supported on the first jaw member and the second pin is supported on the second jaw member. The stationary cam defines a first cam slot, and the rotary cam defines a second cam slot. The first and second cam slots receive the first and second pins and are configured to releasably secure one of the first or second jaw members to the rotary cam such that the first and second jaw members rotate about the stationary cam in alternating fashion. During each revolution of the rotary cam, the one of the first or second jaw members rotates with the rotary cam a substantially full revolution while the other of the first or second jaw members remains stationary.
Endoluminal sleeve gastroplasty
Devices and methods of endolumenal formation of gastric sleeves are described. Some embodiments allow templating of a gastric sleeve by a gastric bougie, exposing a selected amount of tissue for suturing access, while maintaining sufficient internal working space for suturing within the template lumen.
Thorascopic heart valve repair method and apparatus
An instrument for performing thorascopic repair of heart valves includes a shaft for extending through the chest cavity and into a heart chamber providing access to a valve needing repair. A movable tip on the shaft is operable to capture a valve leaflet and a needle is operable to penetrate a capture valve leaflet and draw the suture therethrough. The suture is thus fastened to the valve leaflet and the instrument is withdrawn from the heart chamber transporting the suture outside the heart chamber. The suture is anchored to the heart wall with proper tension as determined by observing valve operation with an ultrasonic imaging system.
