Definitions

  • ABSTRACT An instrument for taking samples from internal organs of humans and animals in which a cannula for insertion into the organ is detachably connected to a handle portion provided with a plunger pump for drawing the sample into the cannula and a needle of homogeneous material is secured in the pump plunger for axial movement within the cannula and serves to prevent undesired fragments of connective tissues entering the cannula when the cannula passes through the tissues surrounding the internal organ being sampled.
  • a usual hypodermic syringe was used and which was provided with a relatively large cannula having an outside diameter of about 2 mm and a conventionally ground clown point into which a tissue sample was sucked.
  • the tissue samples thus taken are to a high degree mixed with connective tissues from the tissues surrounding the internal organ in question. For this reason, introduction was made of the method of placing into the cannula a needle of a homogenous material, and removing the needle after the cannula had penetrated through the tissues in front of the organ into the organ. The quality of the sample thus taken was improved, but the sampling technique showed, certain disadvantages restricting its application.
  • the large cannula as a matter of fact, in many cases gave rise to complications in the form of bleedings and infections and was somewhat painful for the patient.
  • a device for taking samples from internal organs which was developed at a later date utilizes a capillary cannula with an outer diameter of 0.3 0.4 mm, the point of which is cutoff perpendicularly and ground to a cone angle of 40 50 to form a circular edge.
  • the inconvenience and the risk of complications are at a minimum, and the sample taken, when correctly applying the sampling technique, is substantially free of undesirable connective tissue fragments.
  • the device is not entirely satisfactory since it involves obtaining an accurately adjusted vacuum of about 150 mm water-column for sucking the sample into the cannula.
  • this vacuum has to be connected to a separate pump or suc tion hose, which has made it relatively difficult to handle thedevice in practical use.
  • the sampling technique is improved and simplified.
  • the cannula preferably is so designed in accordance with the above mentioned prior art device that the advantages of a capillary canuia with its special grinding of the point can be utilized.
  • the outer diameter possibly is to be increased to about 0.5 mm, for preventing the needle from being so thin that it would be uncomfortable to insert the needle into the cannula when the instrument is to be cleaned and sterilized.
  • the needle diameter is so adjusted in relation to the inner diameter of the cannula that the play therebetween allows the pump to effect sucking through the gap formed, but prevents the tissue sample sucked in to pass the needle.
  • the length of the needle is so adjusted that its free end terminates immediately outside of the cannula mouth when the plunger is in its end position closest to the cannula.
  • the sliding portion is mounted on a cover plate covering a gap, in which a spring clip runs which is secured on the lower surface of the cover plate.
  • the spring clip embraces the plunger in a groove and acts as a carrier.
  • the gap in the pump tube limits the pump stroke.
  • the outer cross-section of the handle can be given a round shape or, which is more advantageous, an angular shape with slightly rounded corners, or it may be given another suitable shape providing a comfortable and safe grip for the hand holding the instrument in the manner of a thick pencil.
  • FIG. 1 is a view of longitudinal section through the instrument, with the plunger being in its forward position, I
  • FIG. 2 is a view taken along-the line 11-11 in FIG. 1, the view looking in the direction of the arrows,
  • FIG. 3 shows the needle position when the plunger is fully inserted
  • FIG. 4 the needle position when the plunger is fully retracted
  • FIG. 5 is a fragmentary view illustrating the manner in which the needle is secured in the plunger.
  • the instrument shown in FIG. 1 comprises a tubular body defining an elongated pump tube ll having a hexagonal outer cross-section with slightly rounded corners, FIG. 2, so as to provide a safe and comfortable grip for the hand.
  • the grip is improved in that the forward portion of the pump tube 1 is knurled.
  • a long plunger 2 provided with a sealing ring 4 mounted in a groove 3 in the plunger.
  • the plunger 2 is actuated by a finger portion 5 on a cover plate s which is connected with the plunger 2 by a spring clip 7 embracing a groove 19 in the plunger 2.
  • a slot 8 for the spring clip 7 is provided in the pump tube l and limits the length of the pump stroke.
  • An aperture 9 in the pump tube ll connects the interior of the pump tube l with the outer air and brings about a pressure balance immediately prior to the arrival of the plunger 2 at its retracted end position, when the aperture 9 is exposed after a suffi ciently great tissue sample has been sucked into the instrument.
  • the rearward portion of the pump tube l is closed by a-rounded plug ill), and the forward portion of tube 1 is designed as a reduced end piece llll having an axial through bore and a gasket l2.
  • a quick-coupling 13 of a bayonet type serves to detachably connect a capillary sampling cannula 14 to the end piece.
  • the cannula Rd has a pointed end 15, FIGS., 3 and i which preferably is ground conical to form a sharp circular edge, but it also may have another suitable form (not shown).
  • a needle 16 of a homogeneous material is fastened and the needle extendsthrough the axial bore in the end piece 11 and the cannula 11d and terminates in a point 17.
  • the point 1'7 extends immediately outside of the pointed end 15 of the cannula 14 when the plunger 2 isin its inner end position (MG. 3).
  • the diameter of the needle 16 is so adjusted in relation to the inner diameter of the cannula id as to form a narrow gap 18 therebetween, which, during the pumping operation,v allows for a pressure balance between the cannula 14 and the interior of the pump tube ll, but which is sufficiently narrow to prevent the tissue sample taken from passing past the point E7 of the needle (FIG. 4).
  • the needle 16 is mounted detachably in the plunger 2, and more specifically, the plunger 2 is provided with an axial cylindrical hole 20, the forward portion or mouth of which is widened to provide a conical guide 21 for a twice-folded resilient holder 22 of the needle 16.
  • the resilient holder 22 is moved in the direction of the arrow against the plunger 2 with the insertion into the hole ill) being facilitated by the guide 21.
  • the needle 16 having reached the bottom of the hole 20, is resiliently secured in the plunger 2.
  • the force of resilience is sufficient for the needle to to participate in the movements of the plunger 2, but the force is such that the needle easily can be withdrawn from the hole Jill for exchange purposes.
  • the length of the needle T16 is so adjusted that it projects after mounting, some distance outside of the pointed end i5 of the cannula lid. This piece is cut old to align with the pointed end 115.
  • the instrument is then held similar to a pencil with one finger on the sliding portion 5, which is held in its forward position while the cannula 14 is inserted through the tissue surrounding the organ until the pointed end l5 reaches the sampling area in the internal organ.
  • the plunger 2 is slowly retracted by means of the sliding portion 5 at the same time as the cannula M is inserted an additional short distance whereby a tissue sample is sucked into the forward portion of the cannula id in front of the returning needle 16.
  • the plunger 2 exposes the aperture 9
  • the vacuum in the instrument is balanced, and the suction of the tissue sample is completed.
  • the instrument can now carefully be pulled. out while the plunger 2 still is in its retracted position.
  • the sample then removed from the cannula id for examination by moving the plunger 2 to its forward position.
  • An instrument for taking tissue samples from internal organs of humans and animals comprising a tubular body having an open end and a closed end, a plunger mounted for axial movement within the body, said body and plunger constituting a vaccum pump, with said body also serving as a handle for the instrument, a cannula constituting a sampling portion of the instrument, said cannula having an outer diameter of about 0.4 min, means detachahly connecting the cannula to the open end of the body, a needle of homogeneous material, means resiliently supporting the needle in the plunger, said needle extending through the open end of the body into the cannula and terminating in a point located immediately outside the end of the cannula when the plunger is at the end of its strolte towards the open end of the body, the outer diameter of the needle and the inner diameter of the cannula being such as to provide a narrow annular gap between the needle and cannula, said gap allowing for a pressure balance between the cannula and
  • the resilient supporting means for the needle comprises a twice-folded resilient holder and an axial cylindrical hole in the plunger having a widened mouth to form a conical guide into which the holder may be inserted and removed.
