BIOPSY NEEDLE Filed Oct. 29, 1958 Patented Apr. 23, 1940 UNITED STATES PATENT OFFICE BIOPSY NEEDLE Irving Silver-man, Brooklyn, N. Y.

Application October 29, 1938, Serial No. 237,720 2 Claims. 01. 120-2) This invention relates to needles of that type generally known in the art as biopsy needles and has particular reference to the provision of a needle of this type which is certain in its action 8 yet oi comparatively simple construction.

An object of the present invention is to provide a needle oi the type mentioned having means for severing a portion oi! the tissue of the human body, for instance as embodied in a tumor,

10 whereby the same may be examined for pathological diagnosis.

Another object of the invention is the provision of a space within the needle for storing the selected tissue and protecting the same while it is being withdrawn from the body of a patient.

Other and further objects of the invention will become apparent from the following specification taken in conjunction with the drawing.

The invention is illustrated in the accompanyi0 ing drawing, forming part of this specification,

wherein Figure 1 is a side view of a needle embodying I the invention and illustrating the method of its use, Figure 2 is a like view, partly broken away, illustrating a further step in the use of the instrument, t

Figure 3 is an enlarged sectional view of one end of the needle,

Figure 4 is an enlarged sectional view taken along line 4-4 of Figure 3 and Figure 5 is an enlarged view, partly broken away, of the biopsy needle.

- Referring more particularly to the drawing,

there is shown therein an instrument embodying my invention and including a hypodermic needle in having the customary pointed and beveled end I l and the usual needle hub i2.

Rotatably and slidably mounted within the customary passage I: of the needle II is an interior needle having a shank ll adapted to snugly fit within the passage l3 and an operating hub It at its'outer-end. The inner end of the interior needle is split for a goodly portion of its J 4 length, i. e., from point to hub, as indicated at It, the two portions thus formed havinz divergently pointed and beveled inner extremities ii. The split portions of the interior needle are hollowed on their inner faces, as shown at II in Figures 4 and 5.

, For the purpose oi illustrating the invention,

there has been shown in the drawing a portion ll of a human body having a tumor 10 therein andg a specimen removed by this instrument is shownat 2i in Figures 3 and 4.

In operation, it will be seen that when a physician desires to secure a specimen of the interior of a suspected portion of a human body, that, after first anesthetizing the skin with novocain or the like, he plunges the needle ill into the suspected portion until it reaches, for I example, the tumor 20. The next step is the insertion of the interior needle into the tumor itself in the manner indicated in dotted lines in Figure 1. This action causes the points H, by reason of their beveled extremities, the bevels 10 extending in opposite directions, to be spread apart, thus assuring the inclusion of a specimen of the tumor and the holding of such specimen therebetween. The next step is the further insertion of the needle it to a point where it en- 1 closes the interior needle. This action causes the split portions of the interior needle to be compressed together, thus firmly enclosing the desired specimen. Both outer and inner needles are then rotated together, thereby cutting away the lower end 01' the specimen. The needles are then withdrawn as a unit and the specimen 2i may be examined at will.

While but one form of the invention has been shown herein, it will be readily apparent to those skilled in the art that various minor modifications may be made without departing from the spirit of the invention or the scope of the appended claims.

What is claimed is:

1. A biopsy needle comprising two members, one slldable within the other, the inner member being split longitudinally with the split portions thereof substantially straight, and having their extremities pointed and beveled, the bevels extending in opposite directions, whereby the two split portions, constituting prongs, when inserted into the mass of tissue, take divergent paths and move from each other so as to readily engage and include-between them a section of the mass, and, upon the advancement of the outer member over such inner member, become compressed, firmly grasping and maintaining the included section of tissue between them.

2. In a biopsy instrument, an elongated I needle having a hubpat one end, a shank, and two elongated and straight prong members having their free ends beveled, the bevels extending in opposite directions whereby said prong members wheninserted into a mass 01' tissue, take so divergent paths and move from each other thereby engaging and including between them a sec- .tion of the mass into which they have been inserted.
