8 results about "Percutaneous surgery" patented technology

A percutaneous surgical device (10; 110) includes a body (12; 112) and a needle (14; 114) extending therefrom. At least one sensor (20; 120) at or adjacent to the needle (14; 114) is configured to produce cutting data indicative of a force acting on the cutting edge (18) of the needle (14; 114). A controller (22) is communicated with the or each sensor (20; 120) to identify whether a tissue is being cut by the cutting edge (18) based on the cutting data.

Disclosed are systems and methods for biopsy, drainage, drug administration, electrode implantation and / or tumor ablation employing percutaneous procedures for diagnostic or therapeutic purposes, performed by inserting a needle or probe through the skin of patient towards target anatomy using a patient mounted robot.

The utility model discloses a percutaneous operation interventional device based on three axes, which comprises a base, an adjusting table and three groups of connecting arms, clamping mechanisms used for clamping interventional tools are arranged on the base and the adjusting table, and driving mechanisms matched with the connecting arms in number are arranged on the base. The driving mechanisms are arranged in the outline periphery of the upper surface of the base, the connecting arms are movably hinged between the driving mechanisms and the adjusting table, the driving mechanisms independently drive the corresponding connecting arms to rotate so as to adjust the postures of the adjusting table and the intervention tool, and the connecting arms are always located in a projection area of the base in the moving process. The device has the advantages of compact structure and improved operation safety.

A surgical robotic platform operates within a constrained space of an imaging scanner in which a patient resides. The platform includes a gross positioning stage configured to be located outside of the constrained space An end-effector having a rotatable shaft is extendable from the gross positioning stage and into the constrained space of the imaging scanner. The shaft has a proximal end operatively coupled to the positioning stage outside of the constrained space and a distal end configured to be located in the constrained space. The distal end has a medical instrument gripper for holding a medical instrument used in a percutaneous procedure. The end-effector further includes a joint arrangement operatively coupling the shaft to the medical gripper for providing motion to the medical instrument gripper for enabling position and / or orientation control of the medical instrument. A drive module controls the joint arrangement.
