The present disclosure relates generally to the field of medical devices and establishing access to a target within the body, such as placing an access needle into a renal capsule into the human body. In particular, the present disclosure relates to devices and methods for performing a percutaneous nephrolithotomy (PCNL) procedure accurately and efficiently while minimizing exposure of the medical professional to harmful radiation.

A biopsy device includes an elongated probe having a central longitudinal axis, a proximal end, and a distal end. A tissue penetrating tip includes a proximal base and a sharp distal point. The proximal base is secured to the distal end of the elongated probe. The sharp distal point is distal to the proximal base and is aligned with the central longitudinal axis. The tissue penetrating tip has a plurality of concave surfaces annularly arranged to form at least three adjacent pairs of concave surfaces. Each concave surface of the plurality of concave surfaces extends from the proximal base to the sharp distal point. Each adjacent pair of concave surfaces intersect to form a concave curved cutting edge. Cumulatively, the at least three adjacent pairs of concave surfaces form a plurality of concave curved cutting edges that distally terminate at the sharp distal point.

Tactile sensing devices, systems, and methods to image a target tissue location are disclosed. When force is applied to the tactile sensing device, voltage data is detected and visualized on a screen, indicating the target tissue location.

A dermatological skin treatment device is provided. The device comprises a handpiece and a cutting tool, wherein the tool is inserted through the conduit and percutaneously inserted into a tissue disposed within a recessed area of the handpiece. The device and method cut the fibrous structures under the skin that cause cellulite at an angle substantially parallel to the surface of the skin and replace these structures with a non-cellulite forming structure by deploying a highly fibrous mesh through a single needle hole to create a highly fibrous layer directly or through wound healing processes.

A surgical access assembly and method of use is disclosed. The surgical access assembly comprises an outer sheath and an obturator. The outer sheath and obturator are configured to be delivered to an area of interest within the brain. Either the outer sheath or the obturator may be configured to operate with a navigational system to track the location of either device within the brain.

This disclosure describes a surgical instrument comprising a combination femoral nerve localizer and needle placement guide instrument. The instrument may be used with a neuromonitoring system to localize and monitor the femoral nerve during a spinal procedure.

A method for guiding resection of local tissue from a patient includes generating at least one image of the patient, automatically determining a plurality of surgical guidance cues indicating three-dimensional spatial properties associated with the local tissue, and generating a visualization of the surgical guidance cues relative to the surface. A system for generating surgical guidance cues for resection of a local tissue from a patient includes a location module for processing at least one image of the patient to determine three-dimensional spatial properties of the local tissue, and a surgical cue generator for generating the surgical guidance cues based upon the three-dimensional spatial properties. A patient-specific locator form for guiding resection of local tissue from a patient includes a locator form surface matching surface of the patient, and a plurality of features indicating a plurality of surgical guidance cues, respectively.

Insertion devices, systems, and methods for inserting a needle into a target tissue in an individual in need thereof are disclosed herein. Also disclosed herein are needle cartridges comprising a needle, a plate, and a needle holder. Also disclosed herein are methods of introducing a catheter into a target tissue in an individual in need thereof.

The exoskeleton (10) for assisting surgical positioning is made of biocompatible material and formed to be substantially form-preserving. The exoskeleton (10) comprises a shell (11) having a coupling surface (15b) fitting to at least a part of a surface of an organ to be operated, and a guiding channel (13) is formed in the shell (11) at a predetermined position, said guiding channel having a predetermined orientation with respect to said shell and a predetermined cross-sectional area for directing a surgical tool to the organ to be operated.
