Abstract
A sniper needle has a tubular passage 3 mounted on a pillar 2 attached to the hub 1 of the needle 4 so that the tubular passage can be used to precisely guide another needle or probe to a predetermined site.
Description
I Sniper Needle 2356143 This invention relates to a needle that can be
used to perform medical procedures, such as Internal jugular cannulation much more safely than by the methods presently available. A small-bore shorter needle is often used to seek out the primary location of a structure before passing a longer wide bore needle. This is to prevent accidental damage to the vital structures in the vicinity. But the smaller needle has nothing to guide the larger needle by to the identified site. The only guide for the larger needle is the direction of the smaller needle. This frequently results in loss of direction, and delay or failure of the procedure. The object of the present invention is to provide a needle that can precisely guide a longer wide bore needle to the identified site. Accordingly, this invention provides the smaller needle with an attachment to guide the larger needle to its target. This attachment must be made of tough, unbreakable material that can be sterilised for use during medical procedures. A preferred embodiment of the invention will now be described with reference to the accompanying drawing in which: Figure 1 shows side view of the invention Figure 2 shows the invention as viewed from the hub end of the needle Figure 3 shows the sniper needle with a large bore needle passed through the attachment. As shown in Figure 1, the sniper needle consists of the hub 1 of the needle 4, to which is attached a vertical pillar 2. A long narrow tubular passage 3 is attached to the upper end of the pillar and runs the whole length of its upper border. Figure 2 shows the arrangement as seen from the hub of the needle.
2 The tubular passage slopes from behind forwards towards the tip of the needle so that any other needle passed through this would come to lie with its sharp point approximated close to the sharp point of the sniper needle as shown in figure 3. The length, the angle and the diameter of the tubular passage are crucial to the construction and can be varied depending on the nature and the site of the procedure. When the whole length of the large bore needle used for a particular procedure is inserted through the tubular passage as shown in Figure 3, the proximal part of the passage would be against the hub of the larger needle. At the same time, the tips of the two needles would be close together. The larger needle should not project beyond the tip of the sniper needle. The diameter of the tubular passage should be just enough for the large bore needle to pass through and should not- allow side to side swaying of the large needle along its long axis. To perform a procedure such as internal jugular cannulation the sniper needle is first attached to a syringe. The needle is inserted through the skin with a constant suction applied through the syringe. The site would be identified by the flow back of body fluids into the syringe. Once the site is reached, the needle is held by the nondominant hand to maintain the position and the appropriate large needle is passed to its full length through the tubular passage to hit the target. Once the procedure is completed, the needles can be withdrawn simultaneously.
3 3 Claims
1. A Sniper needle consists of the hub of the needle to which is attached a vertical pillar with a tubular passage designed to precisely guide another needle or instrument to the tip of the sniper needle.
2. A Sniper needle as claimed in Claim I wherein the tubular passage mounted on the pillar is of a predefined length and width to precisely guide another instrument to a predetermined site.
3. A Sniper needle substantially as described herein with reference Figures I - 3 of the accompanying drawing.
