Definitions

  • the invention relates to a device for inserting a drain into a wound with a needle having a sharp frontal end and a rear end which is provided with an attaching means for connecting the drain with the needle.
  • a drain is drawn from the wound side through the skin to the outside.
  • the sharp frontal end penetrates the skin and forms an opening for the drain to pass through.
  • the drain is detached from the needle and attached in a manner known in itself to an apparatus (such as a Redon bottle) for draining off wound fluid and the like.
  • the device according to the invention is characterized by a handle which is detachably connectable to the rear end of the needle and which is provided with a central channel for at least partially receiving the drain.
  • the needle itself may be less long than the conventional needles . This is an important advantage as said needles are generally used only once. A shorter needle produces less waste, resulting in a reduction in costs.
  • the handle may be reused.
  • the rear end of the needle in cross section has a polygonal, for example, hexagonal part, whereas the cen- tral channel of the handle debouches into a correspondingly shaped recess for receiving the polygonal part of the needle.
  • the cen- tral channel of the handle debouches into a correspondingly shaped recess for receiving the polygonal part of the needle.
  • the polygonal shape of the rear end of the needle and the corresponding recess in the handle have essential- ly two advantages. For one thing, a non-rotating connection between the needle and the handle is provided, so that by manipulating the handle, the needle, which is generally curved, may be brought into the most ideal position. Also, the polygonal shape facilitates fitting the needle into the handle, since the two parts always only need to rotate slightly with respect to each other in order for the two corresponding parts to fit together. For instance, if a hexagonal shape is involved, a reciprocal rotation of only 60° will be required in the most unfavourable situation.
  • the recess formed in the handle has an outer cylindrical part with a diameter that is slightly smaller than the maximum diameter of the inner polygonal part of the recess.
  • the polygonal rear end of the needle must first pass the outer cylindrical part of the recess in order to be able to engage the inner polygonal part of the recess . In this manner, the needle in its final fixed position is locked to prevent unintentional detachment .
  • the difference in diameter between the outer cylindrical part and the inner polygonal part then depends on the desired locking effect . Too great a difference in diameter should be avoided, as otherwise the movement of the polygonal rear part of the needle through the cylindrical part will become very difficult or even impossible.
  • an embodiment of the device according to the invention is preferred in which the end of the handle to be connected with the needle, tapers. This affords a smooth transition between the rear end of the needle and the frontal end of the handle, whereby unintentional damage to tissues can be prevented.
  • the material for the manufacture of the handles will be selected with a view to the application. If it is a matter of a reusable handle, the material will have to be resistant to the appropriate cleaning and sterilization methods .
  • Figure 1 shows a side view of a needle for use in the device according to the invention
  • Figure 2 shows a side view of a handle for use in the device according to the invention
  • Figure 3 shows a longitudinal section of the handle of Fig. 2;
  • Figure 4 shows a cross-sectional view of the handle of Fig. 2 according to line IV-IV;
  • Figure 5 shows a cross-sectional view of the handle of Fig. 2 according to line V-V
  • Figure 6 shows a cross-sectional view of the handle of Fig. 2 according to line VI-VI.
  • the device according to the invention for inserting a drain into a wound comprises a needle 1 shown in Fig. 1 and a handle 2 shown in Fig. 2.
  • the needle 1 At its frontal end the needle 1 has a sharp point 3 and at its rear end an attaching means 4 for a drain 5, indicated by the dotted line.
  • the attaching means may be a stub provided with a fine thread, over which the end of the drain 5 is clasped.
  • the rear end of the needle 1 which in cross section is seen to have a hexagonal part 6, directly adjoins to the attaching means 4.
  • the needle 1 in the conventional manner, is curved.
  • the handle shown in Fig. 2 in side view and in Fig. 3 as longitudinal section, is substantially shell-shaped with a central channel 7.
  • the central channel debouches into a likewise hexagonally shaped recess 8 and an adjoining cylindrical part 9.
  • the interior shape of the hexagonal recess 8 corresponds to the exterior shape of the hexagonal part 6 of the needle 1.
  • the inside diameter of the cylindrical part 9 is slightly smaller than the maximum inside diameter of the hexagonal recess 8 (that is to say the distance between two diametrically positioned angular points of the hexa- gon) .
  • the diameter of the cylindrical part of the needle 1, immediately adjacent to the hexagonal part 6, is slightly smaller than the maximum outside diameter of said hexagonal part 6. This allows the needle 1 to be fitted tightly into the handle 2. To this end the hexag- onal part 6 is pushed with some force through the cylindrical part 9 of the handle 2 until the hexagonal part 6 is admitted in the hexagonal recess 8. The drain 5 then extends through the central channel 7.
  • the handle 2 at the position of the recess 8 and the cylindrical part 9, is shaped to taper. When assembled, this will result in a gradual transition from the needle 1 to the handle 2.
  • Figs. 2 and 3 finally, show that in its wall the handle 2 is provided with two slot openings 10 and 11 which connect diametrically to the central channel 7. Said slot openings 10 and 11 form a connection between the surroundings and the central channel 7, making said channel easily accessible for cleaning and sterilizing.
  • the exterior of the handle 2 also has a polygonal, for instance, hexagonal form, providing a good grip on the surface of the handle 2. Of course, other surface profiles are also possible.
  • a drain 5 is " first connected to the rear end of the needle 1, in accordance with Fig. 1.
  • the drain 5 is pushed via the cylindrical part 9 and the recess 8 into the central channel 7 of the handle 2 , far enough for the hexagonal part 6 of the needle 1 to be admitted in the hexagonal recess 8 of the handle 2. Then the handle 2 is taken into the hand and the needle with its sharp point 3 is drawn from the wound through the skin to the outside. When the needle 1 has penetrated the skin sufficiently far, the handle is detached from the rear end of the needle and removed backward over the drain 5. The needle 1 can then be grasped on the outside of the skin and pulled outward so far that the frontal part of the drain 5 is also outside the skin. Finally, the drain 5 is detached from the needle 1 and attached in a manner known in itself to an apparatus (such as a Redon bottle) for draining off wound fluid and the like.
  • an apparatus such as a Redon bottle

Abstract

Cette invention concerne un dispositif permettant d'insérer un drain dans une blessure, lequel fait appel à une aiguille qui possède une extrémité avant pointue ainsi qu'une extrémité arrière équipée d'un système de fixation permettant de connecter le drain à ladite aiguille. Ce dispositif comprend également une poignée amovible qui est connectée à l'extrémité arrière de l'aiguille, et qui comporte un canal central permettant de recevoir une partie au moins du drain. La connexion entre l'aiguille et la poignée peut se faire par l'intermédiaire de l'extrémité arrière et polygonale de ladite aiguille, ainsi que d'un renfoncement d'une forme correspondante pratiqué dans la poignée.
