The present disclosure in one aspect provides an adjustable depth drill guide comprising a trigger assembly further comprising a trigger and a primary actuating element and a telescopic rotational assembly which abuts the primary actuating element and further comprises an intermediate actuating element. The drill guide described herein allows a surgeon to adjust the depth of the drill guide using only one hand while in-situ.

Briefly, the invention relates to a surgical tool and method for forming a pilot bore by inserting a guide wire into bone. More particularly, the device includes a cannulated hand grip and driving tool used for the rotation of a pedicle screw into bone. The rear portion of the hand grip includes a slide assembly that is suited to grip a guide wire. The slide assembly includes a user adjustable stop to control the sliding movement of the guide wire. The rear surface of the slide assembly is constructed to be impacted with a hammer or similar device, whereby the stop prevents the guide wire from penetrating the bone further than desired. Should it be desired that the guide wire be retracted, a screw jack is included to allow the guide wire to be precisely retracted.

A surgical tool adaptor (10) includes a distal interface member (12) and a proximal holder (14). The surgical tool adaptor is formed with a lumen (16) through the distal interface member and the proximal holder for passing a guiding element (24), e.g. a K-wire, distally through the distal interface member. The proximal holder includes a locking element (26) for locking the guiding element in the lumen and the distal interface member includes a connecting element (18) for connecting to a surgical tool. The proximal holder is movable relative to the distal interface member so that the proximal holder is movable to a position wherein the guiding element does not protrude proximally out of the proximal holder.

Tool assemblies, system, and methods for manipulating tissue and methods for performing a surgical procedure on a vertebral body adjacent soft tissue. A dilator probe is configured to be attached to a robotic manipulator. A sleeve is disposed coaxially around the dilator probe and releasably engaged with the dilator probe. A navigation system tracks the vertebral body and defines an insertion trajectory with respect to the vertebral body. Controller(s) control the robotic manipulator to align the dilator probe and the sleeve to the insertion trajectory and advance the dilator probe and the sleeve along the insertion trajectory to penetrate the soft tissue. After penetration of the soft tissue, the sleeve remains embedded in the soft tissue and the dilator probe is robotically or manually retracted to disengage from the sleeve to enable the sleeve to create a working channel through the soft tissue.

Briefly, the invention relates to a surgical tool and method for forming a pilot bore by inserting a guide wire into bone. The surgical tool is constructed and arranged for use in conjunction with X-ray or ultrasound machines. More particularly, the device includes a cannulated hand grip and driving tool used for the rotation of a bone or pedicle screw into bone. The rear portion of the hand grip includes a slide assembly that is suited to grip a guide wire. The slide assembly includes a user adjustable stop to control the sliding movement of the guide wire. The rear surface of the slide is constructed to be impacted with a hammer or similar device, whereby the stop prevents the guide wire from penetrating the bone further than desired. Should it be desired that the wire be retracted, a jack member is included to allow the wire to be precisely retracted. The hand grip is securable to various surgical driving tools for the purpose of providing the ability to cooperate with various brands of pedicle screws and other surgical implants for spinal procedures.

The Infrared Endoscopic Probe represents a new instrument to bore pilot holes in vertebra pedicles while imaging the operation in the infrared spectrum with an integrated fiber optics endoscope. The pilot holes are bored to provide entry points for pedicle screws that serve as anchor points for spine stabilizing rods to treat several spine conditions. The device consists of a metal body that terminates in a tapered incision tip, an endoscope that runs inside said metal body, a handle to drive the device into pedicle boney tissue and a fiber optics harness that enters the device handle and is used to connect to imaging, illumination, irrigation and suction devices to enable the endoscopic functions of the device. The fiber optics harness connects to an imaging camera that provides an electrical signal to a monitor to view the operation in real time. A method is described to accomplish this procedure.

The present invention is directed to an innovative pedicle probe that uses a force-sensing electromechanical system coupled with haptic and visual feedback. The probe of the present invention reduces the rate of pedicle screw breaches during spinal fusion surgery. The probe provides an effective guidance system to aid surgeons in detecting and preventing cortical bone breaches, thereby minimizing risk of intraoperative injury to the patient. Moreover, the probe invention decreases surgeon reliance on intraoperative radiation, reducing harmful exposure to both patients and surgeons.

The invention relates to a system for determining the quality of a bone structure, comprising: a body adapted for drilling through the bone structure; a first electrode arranged on the body so as to come into contact with the bone structure during drilling; a second electrode arranged on the body so as to come into contact with the bone structure at a distance from the first electrode during drilling; an electric generator adapted to apply an electric current between the first and second electrodes for a pre-determined period of time; a measuring device adapted (i) to measure the electric current, continuously and over the pre-determined period, an electrical magnitude representative of the aptitude of the bone structure for allowing electric current to pass therethrough and (ii) to deliver, continuously and over the pre-determined period, a signal representative of the quality of the bone structure between the contact surfaces of the first and second electrodes, using the determined electrical magnitude.

A system and method of neurostimulation that is coupled with spinal fixation or the spine, implanted at the time of spine surgery, and allowing for a delayed minimally invasive connection to a stimulation source. The components of the system include the conduit anchor that secures to the instrumentation or spine; conduit housing through which leads enter and channels are isolated; the conduit cap to protect the implant; the lead adaptor entry port, wherein leads enter and channels are isolated; the lead adaptor pin housing, which contains contact pins; the keyed MIS tube, through which the lead adaptor is implanted in a second surgery; a grooved applicator to assist with lead placement; and an encircling clip to assist in securing a lead. The method of generating a signal in the frequency domain is described. The method of minimally invasive stimulation trial placement is described.
