A surgical device is defined as a single-impulse suturing device. The single-impulse suturing device allows both suturing and grasping a needle at the opposite end for one time without any need for another tool to retrieve the needle after being passed through a tissue during the suturing process, and the single-impulse suturing device includes the following characteristics of; allowing a safe and minimal invasive access to narrow and deep surfaces; performing a well-directed suturing from a determined point due to its semi-mobile jaw structure, having a stopper that enables suturing by staying at a distance from neurovascular structures in an invisible area, and allowing a multiple suturing with the same needle. The single-impulse suturing device keeps suturing function of the single-impulse devices reserved and develops the same in addition to combining this function with ergonomic size characteristics and practical handle advantages of double-impulse devices.

A removal tool uses magnetic attraction to guide the removal tool toward an implantable device subcutaneously implanted in subcutaneous tissue of a host and to remove the implantable device from the host. The removal tool may include first and second lever members that are pivotably connected together, and the first and second lever members include a pair of jaw members configured to move between open and closed positions to grasp the implantable device. The first jaw member may include a magnet to magnetically attract and couple to an implantable device implanted subcutaneously below a skin surface of a host.

A surgical instrument has an ultrasonic blade that connects to a distal end of an ultrasonic waveguide. A clamp arm assembly is moveable from an opened position for receiving a tissue, toward a closed position for clamping the tissue. A clamp arm actuator connected to the clamp arm assembly directs the clamp arm assembly from the opened position toward the closed position. An outer sheath surrounds at least a portion of the ultrasonic waveguide. The outer sheath includes a cover removably received against a sheath body, and a sheath securement feature able to detachably couple the cover to the sheath body such that the cover can be detached from the sheath body for accessing the ultrasonic waveguide within the outer sheath.

Methods and apparatus for treating disorders of the ear, nose, throat or paranasal sinuses, including methods and apparatus for dilating ostia, passageways and other anatomical structures, endoscopic methods and apparatus for endoscopic visualization of structures within the ear, nose, throat or paranasal sinuses, navigation devices for use in conjunction with image guidance or navigation system and hand held devices having pistol type grips and other handpieces.

The disclosed technology includes improved microsurgical tools providing multiple degrees of freedom at the wrist level, including roll, pitch, and grasp DOFs, a tight articulation bending radius, low radial offset, and improved stiffness. Some implementations include an end effector platform moveable along a fixed trajectory on a fictional axle so as not to interfere with a central-axis aligned working channel; a crossed-arm mechanical linkage for articulating an end-effector platform throughout a pitch DOF with an amplified pitch angle; and a partial pulley system to articulate the arms while maximizing pulley radius to shaft diameter, and permitting a constant transmission efficiency to the arms throughout the range of articulation. In some implementations, a tool shaft outer diameter may be smaller than 3 mm; a pitch DOF range may be 90, a roll DOF range may be 180, and a grasp DOF range may be 30.

A surgical forceps includes a first shaft member including a proximal portion having a handle at a proximal end thereof and a distal portion having a jaw member at a distal end thereof. The proximal and distal portions are pivotable between an aligned position and an angled position. A second shaft member includes a jaw member at a distal end thereof and a handle at a proximal end thereof. The shaft members are pivotable relative to one another between a spaced-apart position and an approximated position for moving the jaw members relative to one another between an open position and a closed position to grasp tissue therebetween. The proximal portion of the first shaft member is pivoted relative to the distal portion of the first shaft member from the aligned position to the angled position upon movement of the first and second shaft members towards the spaced-apart position.

A forceps having at least a first jaw with a longitudinal axis is disclosed. The first jaw can include a body portion, a first flange, a second flange and a cam pin. The first flange can define a first cam slot with a longitudinal extent along the longitudinal axis. The second flange can be spaced from the first flange a distance transverse to the longitudinal axis of the first jaw and can have a second cam slot. The cam pin, with a longitudinal axis, can be moveably secured within the first cam slot and the second cam slot. A diameter of the cam pin can be less than a width between a first longitudinal edge that defines a first side of each of the first cam slot and the second cam slot and a second longitudinal edge that defines a second opposing side of each of the first cam slot and the second cam slot so that the cam pin is moveably received by both the first cam slot and the second cam slot. With the first jaw pivoted to at least a first position, the cam pin and first flange can be configured such that the first longitudinal edge is contacted by the cam pin but the second longitudinal edge is spaced from the cam pin. The cam pin and second flange can be configured such that the first longitudinal edge is spaced from the cam pin but the second longitudinal edge is contacted by the cam pin.

Forceps can include an outer tube, a first jaw, a second jaw, and an inner tube. The outer tube can extend along a longitudinal axis and can include a pair of outer arms extending from a distal portion of the outer tube. The first jaw can be pivotably connected to the outer tube and the first jaw can include a first flange and a second flange each located at a proximal portion of the first jaw. The first flange and the second flange can each include a proximal portion extending outward of the outer tube when the jaws are in an open position. The proximal portions can be shaped to limit extension of the proximal portions laterally beyond the outer arms.

A surgical tool can include a shaft, a pin, an end effector, and a translating member. The shaft can define a longitudinal axis. The pin can be located at a distal portion of the shaft. The end effector can be connected to the shaft. The translating member can be positioned laterally inward of the shaft. The translating member can include a track and the pin can extend into the track to limit translation of the translating member along the longitudinal axis with respect to the end effector.

A forceps having a first jaw and a second jaw, where at least one of the first and second jaws is capable of moving between an open position and a closed positions. The forceps including an inner shaft located within an outer shaft and extending along the longitudinal axis, and a drive bar coupled to and extending distally from the inner shaft. The drive bar including a pair of drive bar struts extending from a distal portion of the inner shaft and positioned laterally inward of at least one of first and second set of flanges of the first and second jaws. A drive pin is securable to the pair of drive bar struts and the drive bar is translatable within the outer shaft to translate the drive pin to move the first jaw and/or the second jaw between open and closed positions.
