3 results about "Fine-needle aspirate" patented technology

Disclosed is a method for examining cells including: acquiring image data of cells acquired from a region suspected to be a cancer lesion; analyzing the image data; determining whether an amount of the cells is sufficient based on the analyzed result; and determining whether cancer-probable cells are included in the cells based on the analyzed result and the determined result; wherein the cells are acquired through Fine Needle Aspiration (FNA).

An automated rapid on-site evaluation (ROSE) system for smearing, staining and capturing a digital image of a biological sample such as a fine needle aspiration (FNA) sample is presented. The system comprises a housing with a user interface monitor or screen, a smearing system, a staining system, and an image capture system. The housing can further include a receiver for a biological sample that can direct the sample to a sample slide. The smearing system is configured to smear the sample on the sample slide. The staining system is configured to stain the sample. The image capture system is configured to capture a magnified image of the sample and store the digital image in the housing or remotely. The digital images may be available immediately for local or off-site review. The wait time between staining the sample and image capture can be less than 60 seconds.

The described technology pertains to a sampling device (100) designed for fine-needle aspiration, addressing challenges in obtaining high-quality cytological samples. The device comprises a body (110) configured to hold a disposable syringe (120), a first actuator (130) for sliding the syringe housing (121) along its longitudinal axis (122), and a second actuator (140) for sliding the syringe plunger (123) along the same axis. A control arrangement (160) operates the device in various modes, including loading, idle, ready, sampling, and unloading, by controlling actuator movements within predefined stroke limits. The device facilitates precise sample collection through synchronized or independent actuator motions, creating vacuum conditions and enabling reciprocating movements for tissue extraction. The assembly includes a disposable syringe and needle (150), and the method involves sequential operational modes for sample collection and preparation for analysis. The described technology enhances diagnostic accuracy, reduces operator dependency, and minimizes patient risks.
