Novel stay suture devices and stay suture combinations with meshes are disclosed. The stay suture devices have a clip and a suture. The clip has leg members that are mounted to a hernia mesh implant such that the leg members are locked in a closed configuration. Also disclosed are novel methods of mounting stay sutures to a surgical mesh implant and repairing a body wall defect such as a hernia defect.

A purse string suture instrument includes an end effector with first and second jaws disposed at a distal portion of an elongate tubular shaft. The first and second jaws are pivotably coupled to each other and to the elongate tubular shaft. The first and second jaws are spaced apart and define a gap therebetween. First and second pluralities of teeth extend perpendicularly from the first and second jaws respectively, and the first plurality of teeth is longitudinally offset from the second plurality of teeth. The first and second jaws are transitionable between open and approximated configurations. The approximated configuration is adapted to clamp tissue in the gap between the first and second jaws, thereby displacing sections of tissue outwardly between the first and second pluralities of teeth.

An ultrasonic surgical device comprises a handle assembly, a shaft assembly, and a removable transducer module. The transducer module includes a waveguide, a locking mechanism, and an electronics assembly including at least one button. The handle assembly includes a trigger assembly configured to actuate the button(s) of the electronics assembly when the transducer module is coupled with the handle assembly. The shaft assembly engages the waveguide of the transducer module and is disposed at the distal end of the handle assembly. The distal end of the shaft assembly includes a harmonic blade. When assembled with the handle assembly, the transducer module is capable of providing ultrasonic energy to the harmonic blade.

Devices and methods are provide for facilitating registration and calibration of surface imaging systems. Tracking marker support structures are described that include one or more fiducial reference markers, where the tracking marker support structures are configured to be removably and securely attached to a skeletal region of a patient. Methods are provided in which a tracking marker support structure is attached to a skeletal region in a pre-selected orientation, thereby establishing an intraoperative reference direction associated with the intraoperative position of the patient, which is employed for guiding the initial registration between intraoperatively acquired surface data and volumetric image data. In other example embodiments, the tracking marker support structure may be employed for assessing the validity of a calibration transformation between a tracking system and a surface imaging system. Example methods are also provided to detect whether or not a tracking marker support structure has moved from its initial position during a procedure.

A hand tool has a pivot connection pivotally attaching a first arm to a second arm, with the pivot connection fixed relative to the first arm and movable to first and second positions relative to the second arm. A spring urges the pivot connection into the first position. When jaws on the front ends of the arms clamp tissue with force greater than a pre-set threshold, the spring force is overcome and the jaws may move linearly apart, allowing for more uniform clamping of the tissue. The first arm may have an arm spring extending between a front segment pivotally attached to a rear segment of the first arm.

A surgical retractor is disclosed herein. In some embodiments, a surgical retractor includes a body extending from a proximal end to a distal end and having a first portion coupled to a second portion via a hinged connection, wherein the first and second portions are configured to rotate about a body axis; a first radiolucent tip coupled to a distal portion of the first portion; a second radiolucent tip coupled to a distal portion of the second portion; a holder coupled to one of the first or second portions; and a deformable member extending through the holder, wherein the deformable member is configured to be deformed to facilitate fixation of the surgical retractor at a desired location.

A surgical instrument (100) includes first and second shaft members (110, 120) defining proximal and distal end portions (112a, 122a, 112b, 122b) and including handles (114, 124) at the proximal end portions (112a, 122a) thereof. A pivot member (130) couples the distal end portions (112b, 122b) with a gap (G) defined therebetween proximally of the pivot member (130). First and second jaw members (210, 220) extend distally from the shaft members (110,120), distally of the pivot member (130). A lockout bar (160, 560, 660, 760) is movable between an unlocked position, withdrawn from the gap (G), and a locked position, disposed within the gap (G). The handles (114, 124) are pivotable between spaced-apart and approximated positions to pivot the jaw members (210, 220) between open and closed positions. The handles (114, 124) are yawable between the approximated position and a yawed position to yaw the jaw members (210, 220) between the closed position and a cutting position. The gap (G) provides clearance to permit yawing such that, when the lockout bar (160, 560, 660, 760) is disposed in the locked position, yawing of the handles (114, 124) is inhibited.

The surgical tool (1) is including a main unit (2) including a case (21) and a hollow shaft (22) provided on the case (21), a holder assembly (3) that holds a living tissue (T) in the body cavity, a connector (4) that connects the main unit (2) inserted through the shaft (22) to the holder assembly (3), an operating unit (5) that is provided on the main unit (2) to allow the connector (4) to enter or leave the shaft (22) and a tension adjustor (6) capable of adjusting the tension of the connector (4).

Aspects of the present disclosure are presented for a single surgical instrument configured to grasp, seal, and/or cut tissue through application of therapeutic energy, and also detect nerves through application of non-therapeutic electrical energy. A medical device may include two jaws at an end effector, used to apply therapeutic energy and to perform surgical procedures. The therapeutic energy may be in the form of ultrasonic vibrations or higher voltage electrosurgical energy. One of the jaws may be configured to cut tissue through application of the blade. In addition, one or both of the two jaws may be configured to apply nontherapeutic energy for nerve stimulation probing. The application of therapeutic energy may be disabled while the nontherapeutic nerve stimulation energy is applied, and vice versa. The nontherapeutic nerve stimulation energy may be applied to the use of one or more probes positioned near one or both of the jaws.

A clip-over disposable assembly includes a switch assembly and a disposable body. The disposable body includes a first disposable member, a second disposable member including first and second wall portions, and a third disposable member. The first wall portion defines a first aperture therethrough and a first cavity configured to receive therein a first portion of the switch assembly. The third disposable member includes a third wall portion, wherein a body of the second disposable member and the third wall portion define an opening configured to allow a shaft of a hemostat-style surgical instrument to pass therethrough. The second wall portion and the third wall portion cooperatively define a chamber in communication with the opening and configured to receive therein at least a portion of the shaft of the hemostat-style surgical instrument, wherein the at least a portion of the shaft is received in the chamber from an off-axis position.
