Embodiment Construction

[0014] As used herein, the term "proximal" means the handle end of the device that is held by the user, while the term "distal" means the opposite end. The term "surgical imaging device" means an endoscope that includes CCD, ultrasound, fiber optic and CMOS devices, as well as other devices used to visualize internal parts of a patient's body, such as a laparoscope or bronchoscope.

[0015] The reference shows the tissue sampling needle device 100 Figures 1A-1D One embodiment of a tissue sampling needle device will be described. Such as Figure 1A As shown in a side plan view of , the device includes a proximal handle or hub 102 from which an elongated tubular sleeve 104 extends distally. Cannula 104 includes a cannula wall 106 that defines a cannula lumen 108 . The distal end 110 of the cannula 104 is beveled so as to include a long side 110a that is substantially parallel to the central longitudinal axis of the cannula 104 and extends to its most distal tip end. The shor...

Abstract

A notched tissue-collection needle configured similarly to a fine- needle-aspiration needle is provided with a cutting edge disposed in the notch and configured to excise tissue into the notch for collection. A stylet may be provided through a lumen of the needle during introduction into a patient body. The needle may be provided with echogenicity-enhancing features.

Description

[0001] Cross References to Related Applications [0002] This application is a formal application claiming priority to US Provisional Application Serial No. 61 / 321,243, filed April 6, 2010, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention generally relates to endoscopic surgical equipment. More particularly, the present invention relates to a biopsy needle configured for use during minimally invasive procedures, such as endoscopic surgery. Background technique [0004] Fine needle aspiration (FNA) is a diagnostic biopsy procedure used to obtain a sample from a targeted location within a patient. A thin needle (eg, 19 gauge to 25 gauge) is guided to the target location and suction is applied at the proximal end of the needle lumen to withdraw cells through its distal end. The procedure is typically far less invasive than other biopsy techniques, whether performed percutaneously (for example, to sample suspected breast...
