Embodiment Construction

[0091] Detailed description of the preferred embodiment

[0092] exist figure 1 , generally discloses how a user U (eg a physician) uses an endoscope 40 to guide a biopsy instrument 1 through a body cavity of a patient P to a sample site 50 . By inserting the endoscope 40 through the patient's body cavity and following the insertion of the biopsy instrument 1 into the working channel 41 of the endoscope 40 , the biopsy instrument 1 is inserted into the patient's body to the desired sample site 50 . Such as figure 1 shown and in figure 2 As shown in more detail in , the endoscope is provided with an inlet opening 41a at the proximal end of the remainder outside the patient's body, wherein the biopsy instrument 1 is intended to be inserted into the endoscope via the inlet opening 41a. Endoscope 40 is usually provided with a camera and / or ultrasound probe and is usually connected to screen 44 via a processing unit 45 capable of converting data from the camera or ultrasound ...

Abstract

A biopsy instrument (1) comprising a base member (10) which extends from a proximal end (10a) to a distal end (10b) along a central geometrical axis (A), wherein at least a distal end portion (10b') of the base member (10) is shaped as an elongated hollow tube (10), the distal end (10b) being intended to be at least partly inserted into a tissue (50) from which a biopsy is to be obtained, wherein the hollow tube (10) is provided with a distally facing circular cutting edge (11) defining a mouth (10c) of the distal end (10b) of the hollow tube (10), wherein the hollow tube (10) has, at a distal portion (10b') of the hollow tube (10), a hollow elongated tubular sample acquiring portion (10b') having a smooth interior surface (12). The disclosure also relates to a kit of parts and a method of acquiring a biopsy.

Description

[0001] field of invention [0002] The present invention relates to biopsy instruments. [0003] The invention also relates to a kit of parts. [0004] The invention also relates to methods of obtaining biopsies. [0005] technical background [0006] A biopsy is a medical test, usually performed by a physician, that involves the sampling of cells or tissue for examination. Biopsies are typically taken using a biopsy instrument inserted into the patient's body via an endoscope. A variety of endoscopic biopsy instruments are commercially available today, the bodies of which are biopsy forceps that pinch a tissue sample, or thin needles that aspirate cells by applying negative pressure. [0007] For some diagnostic purposes, a millimeter-sized sample retrieved with forceps is sufficient, but for some types of lesions and tumors (eg, relatively deep lesions or deeply growing tumors), such small and superficial samples are insufficient to make a diagnosis. Thin needles are oft...
