LOADING FIXTURE FOR USE WITH ENDOSCOPIC STITCHING DEVICE
A loading fixture for use with an endoscopic stitching device includes a needle and a loading portion configured to receive jaws of the endoscopic stitching device. The loading portion includes a shuttle configured to detachably support the needle thereon. The shuttle is transversely slidable such that the needle supported on the shuttle engages at least one of the jaws of the endoscopic stitching device. The loading portion further includes guides to position the jaws of the endoscopic stitching device therebetween and a biasing member configured to bias the shuttle toward one of the guides.
Needle for laparoscopic suturing instrument
A surgical needle includes a pair of ends, a mid-region extending between the ends, and at least one grasping feature configured for grasping by a suturing instrument. An end of a suture is secured to the mid-region of the needle in a manner such that the end of the suture defines an oblique angle with at least part of the centerline defined by the mid-region of the needle. The end of the suture may be disposed in a hollow portion of the needle. The grasping feature may include a notch such as a scallop. The suture may be pivotally coupled with the needle via a ball or pin. The needle may have one or more sharp points. The sharp point may include three converging cutting edges, at least two planar surfaces bounded by the three cutting edges, and a rounded surface bounded by two of the three cutting edges.
Laparoscopic suturing instrument with perpendicular eccentric needle motion
A suture needle driving instrument comprises a shaft and an end effector. The end effector is located at the distal end of the shaft and includes a pair of needle grasping arms. Each grasping arm extends along a respective arm axis. The grasping arms are operable to drive a suture needle along a rotational path about an axis, such as one of the arm axes, that is offset from the central longitudinal axis of the shaft. The rotational path may be perpendicular to the axis of the shaft. A needle driven by the end effector may have an arc radius that is greater than the radius of the shaft. At least one of the needle grasping arms may include a dogleg feature positioning a distal portion of the grasping arm outside the radius of the shaft. The instrument may be used through a trocar during minimally invasive surgery.
ENDOSCOPIC STITCHING DEVICE
An elongate shaft assembly for use with a stitching device includes a hub assembly and an end effector. The hub assembly includes insertion and engaging portions. The insertion portion includes a main rod, a rotatable hub operatively coupled with the main rod such that axial displacement of the main rod rotates the rotatable hub, and first and second arms operatively coupled with the rotatable hub such that rotation of the rotatable hub causes reciprocating axial displacement of the first and second arms. The engaging portion is movable relative to the insertion portion between a reload position in which the rotatable hub is in a distal-most position and rotatable independent of axial displacement of the main rod, and a loaded position in which axial displacement of the main rod rotates the rotatable hub.
Suturing Device
Disclosed is a suturing device comprising a lower jaw rigidly attached to an elongated suturing device body, an upper jaw mobile with respect to the lower jaw, and an activation mechanism for actuating movement of the upper jaw, wherein each jaw comprises at least two apertures or channels within the lower jaw configured and dimensioned to allow a suture thread to pass through. Also disclosed is a suturing device comprising an elongated drive shaft, a handle assembly comprising a tubular handle body, at least one movable element connected to the drive shaft, and an activation mechanism comprising an rotatable activation knob for actuating movement of the at least one movable element. A suturing device combining the above-described jaw elements and activation mechanism is additionally provided. Further, kits comprising disclosed devices and surgical methods utilizing the same are also provided.
Suturing instrument with multi-mode cartridges
A surgical kit includes an instrument and two or more cartridges. The instrument includes a body, a shaft assembly, and a cartridge receiving assembly. The cartridge receiving assembly has a movable output feature, which is configured to move in response to activation of the actuation input feature. The cartridges may include a first suturing cartridge and a second suturing cartridge, with first and second suture needles, respectively. The second suture needle may extend along an arc that has a larger radius of curvature than an arc associated with the first suture needle. The cartridges may also include a drive assembly that is operable to drive the needle along an orbital path in response to movement of the actuation input feature. The cartridges may also include features that are operable to apply clips or staples. The cartridges may also include features that are operable to grasp or cut.
METHOD AND APPARATUS FOR LOADING SUTURE
A loader is disclosed that can load a suture and/or a shuttle into a suture device. The loader can have a suture and/or a shuttle that can be moved (e.g., via a loader control) from a non-loaded configuration to a loaded configuration without damaging the suture or the shuttle. The shuttle can be moved from a shuttle first position to a shuttle second position. When the shuttle is in the shuttle first position, a suture device can be positionable in a device space on the loader. When the suture device is positioned in the device space, the shuttle can be moved from the shuttle first position to the shuttle second position. When the shuttle is in the shuttle first position, the shuttle can be outside the suture device. When the shuttle is in the shuttle second position, the shuttle can be inside the suture device.
METHOD AND APPARATUS FOR PASSING SUTURE
A device that can pierce and hold tissue and then pass suture through tissue. The device can have a shuttle that can removably attach to a suture and jaws that can be rotatably opened and closed with respect to each other. The device can have a first jaw having a first jaw channel and a first jaw first stop. The shuttle can have a shuttle longitudinal axis and a shuttle first stop. The shuttle first stop can have a shuttle first stop distal end. The shuttle first stop distal end can be deflectable into the first jaw first stop. When the shuttle first stop distal end is in contact with the first jaw first stop, the shuttle can be passively retained in the first jaw. A method for using the device to repeatedly pass the suture through the tissue without removing the suture or device from the target site.
Angled suture passer and method of use thereof
A suture passer which is sized and shaped to be inserted through the femoral notch during a meniscal repair. The suture passer includes upper and lower jaws that may be straight or that may have an angled offset in relation to the common axis of the suture passer in order to gain an indirect access to meniscal tissue in a constricted space. The jaws of the suture passer may be angled, either to the left or to the right, up to 45 degrees from the central axis of the shaft. The suture passer is also able to grasp meniscal tissue prior to suture passing. A nitinol needle housed within one of the jaws can then be deployed to pass a preloaded suture through the tissue to be captured on the opposite side of the tissue.
Needle reload device for use with endostitch device
A needle reload device includes a loading assembly including a needle holder pulley and a needle release arm. The needle holder pulley includes a base including first and second portions configured to receive a needle. The needle release arm is transitionable between an engaged state, in which the needle release arm engages the needle holder pulley to inhibit rotation of the needle holder pulley, and a disengaged state, in which the needle release arm is disengaged from the needle holder pulley such that the needle holder pulley is rotatable. When the needle release arm is in the engaged state, the first portion of the needle holder pulley is positioned between jaws of a stitching device, and when the needle release arm is in the disengage state, the second portion of the base of the needle holder pulley is positioned between the jaws.
