An anchoring system for cannulas or tools to be inserted into a surgical workspace in the body, particularly the brain, of a patient. The system comprises a grommet which may be fixed to the skull to both secure the system to the skull and protect the skull opening from passage of cannulas and tools, a resilient clip with grasping jaws adapted to firmly grasp a cannula or tool, and a flexible membrane secured to the outer rim of the grommet and the clip.

A needle guide comprising a base to which a pair of horizontal slide bars are secured, the horizontal slide bars including a channel opening running between the bars, a needle stabilizer with a central tube is slideably engaged with the pair of horizontal slide bars, wherein the needle stabilizer extends through the channel opening and has the ability to change positions along a length of the horizontal slide bar, an angular ruler is secured to the base and located proximal to the needle stabilizer to allow accurate adjustment of the angle of the externally adjustable needle guide and one or more virtual visualization bars to aid in visualization using radiography, ultrasound, or magnetic resonance (or any other medical imaging technology) to visualize the virtual visualization bars.

A medical device for injecting fat while simultaneously allowing the injection site to be viewed with ultrasound. The device may comprise a handle with a front portion and a rear portion, a cannula having a cannula tip, extending from the front portion of the handle, and an ultrasound probe attached to the handle, the ultrasound probe comprising an ultrasound head. The ultrasound head is aligned with and spaced apart from the cannula tip, and remains so aligned during the injection process so that the injection area may be continuously viewed during the procedure.

The present disclosure provides methods for forming or enlarging holes in objects. Objects may include bone tissue and methods for fixing matched medical plates to bodies. The movable trocar with toroidal interface is adjustable relative to the surface. The present disclosure also provides for products produced by the methods of the present disclosure and for apparatuses used to perform the methods of the present disclosure.

One or more example embodiments relate to a positioning support system for positioning a medical device based on at least one medical image, the positioning support system comprising at least one channel for the medical device and configured to be pierced with the medical device, the channel configured to be at an acute first angle to a normal of a surface, the channel including a water-containing medium including at least one polymerizable component, the water-containing medium being configured to cure after being pierced with the medical device when the medical device is coated with a polymerization catalyst, wherein the positioning support system is configured to be placed on the surface, and the positioning support system permits the medical device in the water-containing medium to be depicted in the at least one medical image.

A trocar assembly for releasable engagement with an adapter assembly of a surgical stapling instrument includes a bearing assembly for distributing the axial load experienced by a drive member during tissue stapling. The bearing assembly is disposed within a housing between a flange of the housing and a flange of a drive member. The bearing assembly is configured to rotatably support the drive member and includes a thrust bearing, a rigid member, and a compressible member disposed between the thrust bearing and the rigid member. The compressible member includes a first compressed condition having a first thickness during a clamping stroke of the surgical stapling instrument and a second compressed condition having a second thickness during a stapling stroke of the surgical stapling instrument. The second thickness is less than the first thickness.

Interventional localization guides and methods for MRI guided pelvic interventions are disclosed. The interventional localization guides can include a stereotactic perineum positioning device having integrated MR receive coil array and fiducial receive array. The interventional localization guide can also include a physical template for guiding a surgical device, such as a biopsy needle. In various instances, the MRI guided pelvic interventions including co-registering biopsy locations on third party MRI scans.

An apparatus for targeting an injection site using anatomical landmarks includes a first landmark identifier, a second landmark identifier, and a targeting band. The targeting band is connected with the first landmark identifier at a first end and a second landmark identifier at a second end. At least a portion of the targeting band is linearly deformable. In another embodiment, an apparatus for targeting an injection site using anatomical landmarks on a patient includes a targeting band having a first end and a second end, at least a portion of the targeting being linearly deformable, a first landmark identifier pivotably connected to the targeting band at the first end, a second landmark identifier configured to be connected with the second end of the targeting band; and a fastener configured to secure the first and second landmark identifiers to the patient.

A perineal prostate biopsy apparatus comprising a cannula for reaching a prostate gland of an adult human male through his perineum; and a coaxial needle comprising a hollow needle shaft having an open piercing tip at its distal end and being arranged to lie within the cannula so that the piercing tip protrudes from a distal end of the cannula; and, a stylet adapted to lie within the hollow needle shaft so that a distal tip of the stylet closes the piercing tip of the needle.

Methods for accessing a disc space of a patient as a part of an interbody fusion, as well as the tools employed therewith. An exemplary method may include inserting a leading end of a tool into the patient's back at a location on the posterior surface that is laterally offset from a patient's spinous process and disc. The tool's initial entry into the patient may be from a posterior approach. As the tool is advanced along its designated path, it begins to deviate from the posterior approach towards a lateral approach. When the leading end reaches the disc, it may access the disc from a lateral or substantially lateral location. The tool may be used to access the disc location, to remove disc material, to deliver a cutting tool for removing the disc material, and other steps associated with the spinal interbody fusion procedure.
