A stimulation device includes an adapter component to increase the usability of the stimulation device. The adapter may be a bipolar adapter arranged to connect to the housing of the stimulation device. The adapter may include a clip having a first channel configured to receive an operative element therein and a second channel having a return operative element therein. The return operative element is in electrical communication with an electrical circuit of said stimulation control device. Alternatively, the adapter may be a percutaneous adapter comprising a connector configured to connect to an operative element of a stimulation device and a lead wire connected to the connector. A needle may be connected to the lead wire to deliver a electrical stimulation signal to a target tissue located beneath the skin of a subject patient.

A disposable bidirectional ratchet, which has a tubular hollow handle with an interior surface having teeth thereon; a toggle mounted movably within the handle; a knob connected to an end of the toggle moves the toggle inside the handle; a plurality of pins on another end of the toggle; a plurality of actuators each comprising: fingers, levers, toes and a head, and having a post guide formed therein; a plurality of posts affixed to a clutch; and, wherein the actuators are movable affixed to the clutch via the posts, and the pin position selects the direction of engagement via adjustment of the actuator position via applying force to the levers, which moves the lateral edges of the actuator towards or away from the teeth.

Systems and methods for a guide assembly for introducing a bone anchor to an operative target site. The guide includes an outer sleeve and an inner sleeve. The outer sleeve has a distal anchor engaging end, a proximal end, and a central passage extending from the distal end to the proximal end. The inner sleeve may be situated in the central passage of the outer sleeve. The inner sleeve is movable being between a first position and a second position. The first position permits insertion of the bone anchor in the central passage. The second position releasably fixes the bone anchor to the guide assembly.

An apparatus for inserting implants in a bone comprising a frame having a cartridge receiving chamber and a barrel. A cartridge defining a plurality of chambers is positioned in the cartridge receiving chamber so the chambers are selectively alignable with a longitudinal passage of the barrel. At least one instrument is positioned in one of the chambers, and a plurality of implants is positioned in the other chambers. A drive assembly is engageable with the instrument and the implants. The drive assembly is slidably and rotatably disposed in the frame and is moveable between a retracted position, an engaging position wherein the distal end of the drive assembly is positioned to engage the selected one of the instrument and the implants, and an extended position wherein the drive assembly extends through the chamber to transport the selected one of the instrument or the implant from the chamber to the distal end of the barrel.

An anchor for anchoring tensile members to bone includes: a housing extending along a central axis, with a hollow interior; a collet in the hollow interior having a central bore for accepting tensile members and an exterior surface, the collet being configured to swage around and against tensile members; a sleeve having a peripheral wall defining interior and exterior surfaces, the sleeve disposed in the housing's hollow interior axially adjacent to the collet, and movable parallel to the central axis between first and second positions; and wherein at least one of the collet exterior surface and the sleeve interior surface is tapered and the sleeve and the collet are arranged so movement of the sleeve from the first position to the second position causes the sleeve interior surface to bear against the collet exterior surface, causing the collet to swage radially inwards around and against one or more tensile members.

The disclosure describes systems and methods for altering bone sections in a patient. In one embodiment, a system may include an intramedullary implant including: a housing configured to be secured to a first section of bone, where the housing may include one or more shaft engaging grooves axially extending along an inner surface thereof; a distraction shaft configured to be secured to a second section of bone, where the distraction shaft may include one or more grooves axially extending along an inner surface thereof. The system may further include an actuator disposed within the housing and operably coupled to the distraction shaft, and in response to rotation of the actuator, the one or more grooves of the distraction shaft may engage with the one or more shaft engaging grooves of the housing, causing axial displacement of the distraction shaft relative to the housing.

Surgical instruments and methods for delivering bone anchor assemblies into bone are disclosed herein. Use of these anchors or instruments can eliminate one or more of the steps in a conventional bone anchor installation procedure, improving surgical efficiency and safety. In general, a surgical instrument can include a handle assembly having an elongate shaft extending distally therefrom. The handle assembly can be configured to axially translate a stylet extending therethrough relative to a bone anchor assembly coupled to the elongate shaft, and it can be configured to move the stylet proximally in response to distal advancement of a bone anchor assembly into bone. The surgical instruments can include various mechanisms for adjusting the position of the stylet.

A minimally invasive precision cutting guide, targeting guide, implant, and other instruments comprise a system that permits a physician to surgically correct a bunion or similar deformity with a minimum disruption of surrounding soft tissue. The precision cutting guide ensures that the physician cuts bone in the proper location and orientation. Each of the instruments is designed to minimize disruption to surrounding soft tissue. The system also precisely locates an orthopedic implant such that it can fixate two bone fragments after an osteotomy, or two bones after surgery. The precision cutting guide, targeting guide, implant, and other instruments are provided in a sterile kit for the convenience of the surgeon and safety of the patient.

An apparatus to limit a seating depth of a fastener can include a cylindrical housing, a pin, a driver, and a biasing element. The cylindrical housing can include a proximal portion couplable to a tool, a distal portion engageable with a workpiece, and a bore extending from an opening on the distal portion towards the proximal portion along a longitudinal axis of the housing. The pin can be secured to the housing and can extend radially inward into the bore. The driver can be translatable within the bore of the housing and can extend beyond the opening on the distal portion to engage the fastener. The driver can include a slot that can be engageable with the pin to receive a torque from the pin and can rotate with the housing to transfer the torque to a fastener when the pin engages the slot.

The present invention discloses an instrument of medical/dental insertion, the instrument comprising: an axle; a fixing region; and an insertion element; where the fixing region makes the connection of the insertion element and the axle; the axis rotating the insertion element when connected; where the fastening region comprises a magnet configured to fix the insertion element on the axle.

Thus, one of the advantages of the present invention is to eliminate the natural wear that occurs in the retention, mechanical type, between the tools, besides facilitating the handling of instruments.
