Description of the Related Art Generally, a spraying tool for an endoscope is formed by fitting a screw body having a spiral groove formed on the outer periphery thereof into a cap having an injection hole formed at the center of the tip to form a spray nozzle. A spray nozzle is attached to the tip of the tube for feeding the spray liquid into the inside.

ら外れて体腔内に落下してしまう危険性がある。However, the screw body and the cap constituting the spray nozzle must be subjected to extremely precise processing despite being very small parts, so that the production cost is very high. In addition, there is a risk that the spray nozzle may fall off the tip of the tube and fall into the body cavity due to the liquid pressure during spraying.

口形成したことを特徴とする。In order to achieve the above object, an endoscope spraying device according to the present invention has a spiral groove formed at least on an inner peripheral surface near a distal end of a flexible tube through which a spraying liquid passes. It is characterized in that an opening is formed at the tip of the flexible tube.

In FIG. 1, reference numeral 1 denotes a flexible tube formed of, for example, tetrafluoroethylene resin for passing a spray liquid, and can be freely inserted into and removed from a forceps channel of an endoscope.

の噴出口３が、前方に向けて開口形成されている。[0008] A spiral groove 2 is formed on the inner peripheral surface of the flexible tube 1 over substantially the entire length, and the distal end portion of the flexible tube 1 is tapered, and a flexible portion is formed at the center of the distal end. A spout 3 having a diameter smaller than the inner diameter of the spiral groove 2 of the sex tube 1 is formed to open forward.

め込まれている。A luer lock base 4 for connecting a syringe (not shown) is connected to the proximal end of the flexible tube 1. In the flexible tube 1, a metal core 5 having a thickness substantially covering the inner diameter of the spiral groove 2 is inserted from the luer lock base 4 side to just before the tip.
The base end is wound in an annular shape and fitted into the bottom of the luer lock base 4.

に接続して、可撓性チューブ１内に散布液を注入する。When using the endoscope dispersing tool constructed as described above, the flexible tube 1 is inserted into the forceps channel of the endoscope, and the ejection port 3 at the distal end is set in the target cavity in the body cavity. After aiming at the site, insert the syringe containing the spray liquid into the luer lock base 4
And the spray liquid is injected into the flexible tube 1.

れる。Then, since the inner diameter portion of the spiral groove 2 in the flexible tube 1 is closed by the metal core 5, the spray liquid flows in the spiral groove 2 and spirally rotates around the axis. While spraying forward, the spray is sprayed outward at a wide angle from the thin jet port 3.

芯金５を挿入しなくてもよい。The present invention is not limited to the above-described embodiment. For example, the spiral groove 2 may be formed at least on the inner peripheral surface near the distal end of the flexible tube 1. If the inner diameter of the two parts is made very small, the core metal 5 does not necessarily have to be inserted.

するおそれが無く極めて安全である。According to the endoscope spraying tool of the present invention, the spiral groove is formed on the inner peripheral surface of the flexible tube itself, so that the spraying can be performed without attaching any parts to the tip of the flexible tube. Since the liquid can be sprayed, it can be manufactured at a very low cost, and it is extremely safe without the possibility of parts falling off from the tip.
