Abstract
A biopsy needle that is based upon an opening at the tip of the needle, not the side, that permits the entire sample to be cut from the patient yet has smooth sides to reduce injury to the patient when the needle is inserted. The needle of the invention has a coaxial inner needle or tube that allows the opening at the tip to be completely closed and the sample or specimen to be cut off at its point of attachment after insertion of the needle. The needle of the invention samples tissue in front of the needle as it is pushed forward, rather than scraping tissue from the edges of the needle track. In accordance with the invention, the coaxial inner needle can be withdrawn and the sample obtained without moving the outer needle or tube. Several samples can thus be obtained with minimal need for repositioning the needle avoiding pain, tissue damage and risks associated with such repositioning.

CORE BITE BIOPSY NEEDLE
Background of the Invention Tlus application claims priority from U.S. Provisional Patent Application No.
601301,029 filed June 2G, 2001.
This invention relates to hiopsy needles and rnorc particularly relates to neeelles that can cut a tissue sample internally within a patient and then withdraw the sample.
A numbv,~r of biopsy ncccllcs for taking tissue samples are known but unfe~rtunately such known needles have ane tar more serittus diaadvantiiges.
Many of such needles, e.8. as described in U. S. Patents 4,640,296; 5,040,542;
5,492,130;
5,843,023; 5,916,175: European Application 0 455 626; British Application 2 347 8(i2 and International Application WO 00/56220 rely upon an open cutting edge of the needle which cuts around a sample arid forces it into the needle. With such a configuration, the end of the sample is not severed but the operator must move the needle within the patient to finally tear the end of the sample front attached tissue.
Such a procedure in a cc~nscyov.~ patient can he extremely pa.intul fmd trt~umatic and in any case can cause significant tissue damage to areas surrounding the removed Sample. This unsatisfactory proccdut'c is clearly illustrated in British patent application 2 347 862.
Another set of lortown biopsy needles does not cut at the tip c~f the needle but instead relies upon tissue overflowing into a side opcnit'1g which is then cut off by a Slidin8 sheath or other cuttin8 means, Such needles are for example dcscrihecl i.n 11.5.
Patents 4,6(')(),()1.4; 5,224,488; 5,313,958; 5,507,298; and 5,611,352.
~Vlrhil~ such needles are an improvement in that the entire sample is cut ratlier than partially tom frotu a patient, there is another different problem associated with such needles. Tn particular, such needles rely upon tissue overflow into the side opening. The samples, if present at all, arc thus irregular.
At least ont attempt has he~~n made W cut an entire sample while using an opening at the tip of the needle. Such an attempt is dGacrihed in U.S. Patent 4,651,752. Unfurlunalcly, the neCdle structure of IJ.S. Patent 4,651,752 is comrlex with rough sides that can tear and bruise tissue and further would be very dit~icult to make in a small needle.
Brief Description. of the Drawings Fiyre 1 shows a cross sectional view of a preferred embodiment of the biopsy needle of the invention.
Fifiurc 2 shows a tip view of the needle of Figure 1.
Figure 3 shows a top end view t~f ihG needle of Figure 1.
Figure 4 shows a top side perspective view of the nerdle ofFi~.~re 1.
Figure; 5 shows a perspective view of a huh detail. of the needle of the invention.
~I~igure b shows a cmss sectionnl view of the needle with the inner needle P;~rlially withdrawn.
Brief Description of the Invention In accordance with the invention, there is therefore provided a biopsy needle that is based upcm an UPening flt the tip of the needle, not the side, that permits the entire sample to be cut from the patient yet has smooth sides to reduce injury to the patient when the needle is inserted.
The needle of the invention has a coaxial ilmer needle or tube that allows the opening at the tip to be completely closed and the sample or specimen to be cut ofr at its point of attachment after insertion of the needle- 'I'hc needle of lhc invention samples tissue in front of the needle as it is pushed forward, rather than sc,~raring tissue from thv edges of the needle track. In acnorddncC wilh the invention, the caaxi3l inner needle can be withdrawn and the sample ohtaincd withc~ul mewing the vuler needle yr tube. Several samples can thus he obtained with minimal need for repositioning the needle avoidins pain, tissue damafie and asks associated with such repositioning.
Further, in closed position, the needle eau be iuscrtcd through supcrFcial LisSUr, pushing it to the side until a desired biopsy area is reached. The needle may then he opened near its point and further inserted to circumfi;rentially cut d bwpsy sample and the opening may then be closed to cut off the sample- Dsm.age lv superficial tissue and tissue in the area of the biopsy is thus minimir.ecl.
More particularly, the invention is a biopsy needle having an external liollow outer nec;dle (tube) with a smvolh side wall and an end with a point defined by at Icast nee slanted end wall. The end wall is provided with an opcrung so that when the needle is inserted into biological tissue, tissue extends through the end onen;ng in. the external tube. An internal cutter, rotatablc witliin the external hollow tube, is Provided to cut a biological sample within said opening from its point of attachment and to close the opc;ning upon making the cut.
In vmc embodiment, the internal cutter is an internal hallow tube fitting within the external hollow tube. The internal hollow tube has a shape corresponding with the Shape of the external hollow tube, including an end opening corresponding with the errd opening in the exlernul hollow tube so that when the needle is inserted into hiolc~gical tissue, tissue extends thmugh the end openings in both th.e external tube arid internal t<rbe fund rotation of the internal hollow tube cuts the tissue extending through the opening in the internal tube to obtain a cut sample and closes the opening ire the external hollow tube to retain the cut sample.
The internal tube pxcferably slides within the external tube so that after a sample is cut, the internal tube can be withdrawn with the sample from the external tube without disturbing the position of the external tube.
f)elailed f)escriplian u.f. Lh.e Invention A preferred embodiment of the izmenlion ma.y be seen in the drawings. A
biopsy needle 10 of the invenfion includes an outer needle or tube 12 and a coaxially rotatuble corresponding inner needle or tube 14. The outer tube 12 is defined by a smooth sidewall 16 and ttn end 1$ detuied by a slanted cud wall 19 with a point 2U.
The inner W be 14 has a corresponding end 22 witli a point 24 sufficiently smal lee in size to pcrtnit insertion within author tube 12. Ends 18 and 22 are provided with openings 2G and 28 rcspcctivcly. A handle 3U is provided that is attached to inner tube 14 to facilitate its rotation within a slot in a huh 32. 'fhe hub 32 attached to outer tube 12 holds and locks handle 3t) in positicm tn hold it longitudinally secure relative to outer tube 12 when inner tube 14 is rotated so that openings 26 and 2$ are aligtacd, Hub 32 permits rotation of handle 30 and attdc;hed tube 14 s~ that an edge 34 of inner tube 14 can be mewed lc~ cut a samplE and clnse e~pening;, 26 and 2~ by .relative opening offset. handle 3A is however removable fmm hub 32 tea permit withdrawal of handle 3U with attached iz~nex lobe 14 containing a sample, when opening 26 and 28 ~~re vt.'fseh Such an offset position helps to reCa.in the sample us inner tube 14 is removed.
It is to be understood that the invention also includes the method of taking a tissue sample using the biopsy needle of. the invention.
