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.

A laparoscopic suturing device is provided. The suturing device can pass a suturing needle back and forth between jaws of a jaw assembly to suture tissue at a surgical site in a minimally invasive procedure. The jaw assembly can have a pivotable jaw member in each jaw to position the jaw assembly and needle in a low-profile stowed configuration for insertion through a low diameter surgical port. The jaw assembly can be actuated by a handle assembly that provides simultaneous needle passing from a driving jaw to a receiving jaw and latching the needle within the receiving jaw in a single trigger cycle.

The invention relates to a laparoscope suture knot pushing and suturing device. The device is characterized by comprising a guider (11) and a suturing probe (12); the opposite sidewalls of the guider are each obliquely provided with a guide hole (10), the two guide holes are staggered in the opposite directions of the guider, and the suturing probe is correspondingly matched with the guide holes in a guiding mode; the guider comprises a fixed sleeve, a pull rod (3) is connected into the fixed sleeve in a sliding fit mode, one side of the pull rod is connected with a locking handle (2), two movable wing plates (4) are hinged to the two symmetrical sides of the other end of the pull rod respectively, and a silicon thin film sheet (7) is arranged in each movable wing plate; the silicon thin film sheets are arranged on extension lines of the corresponding guide holes after the movable wing plates rotate. The laparoscope suture knot pushing and suturing device has the advantages of being reasonable in design, accurate in locating, ingenious in structure, easy to operate and capable of simplifying the suturing process; compared with a conventional suturing mode, the puncture hole suturing time is shortened obviously, so the laparoscope suture knot pushing and suturing device has an obvious safety function and will not hurt blood vessels in the body of a patient or potential visceral organs.

There are many methods of tying a knot in a surgical suture. One method is to form a loop in the suture and then pull the other end of the suture through the loop. To do this laparoscopically is the object of the present invention. The finger loop handles of two small diameter laparoscopic graspers are sacrificed, and their shafts are then placed within a single common sheath, using also a single common in-line handle. The jaws of the graspers are operated by spring loaded push knobs on the handle. A loop is formed by grasping the same suture at two points a short distance apart simultaneously with the two graspers, and then bringing them together. The present invention is capable of doing this by virtue of one of the two graspers being slide-able, extendable and retractable.
