A treatment device has an arm member having a plurality of arms to have an open state and a closed state; a wire having a distal end connected to the arm member and the distal end is attachable and detachable to the arm member; a sheath through which the wire is inserted; an operator connected to a proximal end of the sheath; a slider connected to the wire and attached to the operator to be slidable toward a distal end or a proximal end of the operator, wherein the slider makes the plurality of arms to be in the closed state when the slider is disposed in a first range, and the slider makes the plurality of arms to be in the open state when the slider is disposed in a second range; and a slider restriction mechanism provided between the distal end of the operator and the slider.

Clamping forceps device includes two clamps in pivotal connection to one another and each having an operator end for being operated by a health care provider. The device also includes an extension extending aft of the operator end of each clamp, the extension forming a space therebetween sized to form a disconnecting wedge mechanism for separating a tube from a patient tube connector. Each extension defines a ramped surface increasing in thickness moving from an extension tip towards the operator end.

A suturing apparatus comprises a pair of jaws. A bendable needle housed in one of the jaws is adapted to carry a suture. A suture receiver is disposed adjacent to, or integral with, the opposite jaw to help disengage the suture carried by the bendable needle. A transition block curves the needle and directs it in a direction generally unparallel to an axis of the carrying jaw. The jaw housing the needle may include a lateral opening through which the suture may be inserted. The needle may also include a lateral notch which may be aligned with lateral opening to receive the suture. An actuator coupled to the needle enables the user to move the needle proximally to align the notch with the lateral slot.

A surgical instrument includes a first member having an inner surface and an outer surface. A second member has an inner surface and an outer surface. At least one of the inner surfaces defines at least one mating element and the outer surfaces are engageable with tissue. The members are relatively movable between a first configuration and a second configuration to space the tissue and define an opening between the members. At least one third member defines at least one mating element engageable with the at least one mating element of the inner surface such that the at least one third member is disposed within the opening. Systems and methods are disclosed.

Devices, methods, and systems are provided for placing an implant into a patient and removing it therefrom.

Bone reduction forceps provide both continuous and discrete adjustment of force. A worm gear rotatably attached to one arm of the forceps engages a rack attached to another arm of the forceps to provide both the continuous and discrete force adjustment. Buttress threads on the worm and/or the rack allow for rapid closure by squeezing the handles of the forceps. Rotating the worm gear allows for fine adjustment of closing force. A five-bar linkage provides increased mechanical advantage and an extra degree of freedom, compared to conventional forceps. Interchangeable tips provide flexibility, allowing a user to customize the forceps to a task or the user's preferences.

A disposable device for tissue retraction, including first and second elongated curved members, each having respective proximal and distal ends, a hinge pivotably connecting first and second elongated curved members, wherein first and second curved members curve away from one another, a first blade extending from the distal end of the first elongated curved member, and a second blade extending from the distal end of the second elongated curved member. The device further includes a first latching portion extending from the proximal end of the first elongated curved member, a second latching portion extending from the proximal end of the second elongated curved member, and a third bladed elongated member lockingly engageable to the hinge. The first and second latching portions are lockingly engageable. The retractor is made of a generally electrically insulating nonmagnetic radiolucent material.

A method of performing an operation, e.g. a spinal operation, on a patient using a retractor comprising a pair of blade assemblies which are adapted to open about a set of axes that are not parallel to a third spatial axis, and further comprising a pair of arms, which are adapted to move the pair of blade assemblies apart from one another in the third spatial axis. In the method, the blade assemblies are closed to assume a low profile, inserted into a relatively small incision, and stretched apart from each other, thereby stretching the skin about the incision to form an aperture longer than the incision. The blade assemblies are then opened by rotating the blades about the set of axes, stretching the skin around the incision in a second direction that is substantially perpendicular to the first direction (i.e. the direction of the incision.).

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 tenaculum includes a first handle and a second handle pivotally coupled to each other about a pivot pin. The first handle includes a palm grip configured to support a palm of a user's hand. The second handle includes a loop defined therein configured to support a user's digit to facilitate pivoting the first handle toward the second handle. A first grasper arm extends from the first handle. A second grasper arm extends from the second handle. The first and second grasper arms are configured to grasp tissue. A first ratchet extension extends from the first handle towards the second handle and a second ratchet extension extends from the second handle towards the first handle. The first ratchet extension is configured to selectively engaged the second ratchet extension upon movement of the first and second handles towards one another to engage tissue between the first and second grasper arms.
