Embodiment Construction

[0034] figure 1 A schematic diagram illustrating a system 100 for aligning an elongate tool (eg, surgical tool 102 , such as a hollow needle) with an occlusion target 104 is shown, according to an example embodiment. In the following description, the system 100 is described with reference to a surgical application, and the occlusion target is a kidney stone 104 . However, it should be understood that system 100 may be used in various other applications.

[0035] System 100 includes adjustment mechanism 106 . Adjustment mechanism 106 is configured to adjust the angular orientation of surgical tool 102 relative to pivot point 108 . The system 100 also includes an imaging device in the form of a C-arm fluoroscopy 110 configured to capture one or more x-ray images of the surgical tool 102 and the occluding target (eg, kidney stone 104 ). The system 100 also includes a processor 112 communicatively coupled to the adjustment mechanism 106 and the C-arm fluoroscopy 110 . The proc...

Abstract

The present invention discloses a system and method for aligning an elongate tool with an occlusion target. The system includes: an adjustment mechanism configured to adjust the angular orientation of the elongated tool relative to a pivot point spaced apart from the target; an imaging device configured to capture one or more of the elongated tool and the target an x-ray image; and a processor communicatively coupled with the adjustment mechanism and the imaging device, wherein the processor is configured to: extract the detail based on image data of the x-ray image received from the imaging device Euclidean vector data for an elongated tool; and controlling the adjustment mechanism to iteratively adjust the angular orientation of the elongated tool based on the Euclidean vector data so as to align the longitudinal axis of the elongated tool with the The target is aligned with the pivot point.

Description

technical field [0001] The present invention broadly relates to a system and method for aligning an elongate tool with an occlusion target. Background technique [0002] Percutaneous kidney access (PAK) or renal access is a minimally invasive procedure used to establish keyhole access in percutaneous nephrolithotomy (PCNL) to remove kidney stones. In this procedure, a trocar (trocar) is passed through the patient's skin through layers of the body and into the kidney to reach the stone target. Surgical instruments such as guide wires, ultrasound probes, and vacuum devices are then passed through the hole in the trocar to perform the stone removal procedure. [0003] Conventionally, the PAK procedure is performed by the surgeon holding a trocar in his hand, with one end of the trocar resting on the patient's skin. The other end of the trocar is tilted several times to establish accurate alignment between the trocar and the calculus target. Trocar alignment was determined wi...
