Description of the Related Art As a treatment method for saphenous varices, sclerotherapy combined with vein ligation and conventional stripping surgery (vein extraction) are widely used. The former is less invasive and allows outpatient surgery, but has a problem of curability, such as frequent recurrence via the femoral perforator. The latter is highly curable,
It is extremely low-invasive and is not possible as a short-term operation. The present inventors have proposed a stripping tool for inversion, which is preferably used for a selective vein removal operation by an internalization method, in particular, a selective vein removal method for LSV, as a surgical method that achieves both high curability and low aggression. I have proposed it earlier.

A needle tube for injecting a liquid medicine characterized by having a structure, or flexibility capable of manually forming the needle tube into a curved shape, and having a small hole for injecting a liquid medicine at least at the tip side portion. The problem can be solved by providing a medicinal solution injection needle tube having a rounded structure in which the distal end portion does not puncture a biological tissue. The drug solution injection needle tube of the present invention has a rounded structure whose tip does not puncture biological tissue so as not to puncture human tissues such as blood vessels as described above.
When inserting the needle tube into the living tissue, it is used after the insertion site is incised with another incision instrument. Further, the curved shape has the function of facilitating insertion of the drug solution injection needle tube into the living tissue, and further having the function of facilitating movement within the body tissue, and inserting the drug solution injection needle tube into the living tissue and It is a shape having a radius of curvature (R) that does not puncture or damage the living tissue when it is moved. In particular, the curved shape is a curved shape in which the entire needle tube has a uniform curvature as shown in FIG. 1, and it is particularly preferable that the degree of curvature is gentle in order to achieve the above-mentioned function. The specific radius of curvature is about 650 to 850 ares, and more preferably about 700 to 780 ares. However, the curved shape or the degree of curvature is appropriately selected according to the location where the drug solution injection needle tube of the present invention is used for living tissue, and is not limited to a specific range. .

Further, the bending portion is formed by manually forming a needle tube which is not curved as shown in FIG. 2 before the operation as described above,
The shape can be formed according to the treatment site, or the size or shape of the treatment site. However, the curved shape may be formed in advance by the manufacturer or the seller of the drug solution injection needle tube. In order to satisfy the above-mentioned various characteristics, it is preferable that at least a part of the base material is made of a copper material as the base material that constitutes the drug solution injection needle tube of the present invention.

Particularly, those having 14 to 16 gauge are more preferable. If the diameter of the needle tube is less than 12 gauge, a large amount of the medicinal solution is injected at one time, and if it exceeds 18 gauge, the injection resistance becomes large when the medicinal solution is injected into the living tissue, and the necessary amount of the medicinal solution is injected. Becomes difficult. Further, the length before forming the curved portion of the drug solution injecting needle tube of the present invention is also not particularly limited as long as it is long so as to achieve the object of the present invention, depending on the site to be treated, One needle tube for chemical injection is L
Since it can be commonly used for both SV and SSV, it is preferably about 20 cm or more. As shown in FIGS. 1 and 2, a needle base portion 6 is attached to the needle tube of the liquid medicine injection needle tube of the present invention. As the needle base portion, it is preferable that a female luer is formed in the portion so that it can be connected to a male luer of a syringe. Further, the female luer has a tapered portion so that the male lure can be easily connected. It is preferable that

有しない閉塞構造であることが好ましい。The drug solution injection needle tube of the present invention is preferably one in which at least one small hole is formed in at least the tube wall at the tip side portion of the needle tube for injecting the drug solution in the needle tube into the human tissue around it. The number of the small holes may be one or more, but if the number of the small holes is too large, it becomes difficult to inject the liquid only into the target site, and the holes formed with a large number may be used. The chemical solution leaks to other parts, resulting in poor efficiency. It is not possible to evenly infiltrate large amounts of solution at one time around human tissue, such as LSV or SSV. Therefore, the number of the small holes is preferably about 1 to 3. When the number of small holes is 3 or more, the drug solution is injected into the living tissue at one time, and it becomes difficult to efficiently wet the drug solution to the target site of the living tissue. When the number of the small holes is plural, the positions of the plural holes provided in the side wall of the needle tube may be formed only on one side of the side wall, but they are formed alternately on different side walls, particularly opposite side walls. However, it is preferable from the viewpoint that the chemical can be efficiently moistened. Also, all the small holes are 35 mm from the tip.
It is preferable to be formed within the range because the liquid medicine can be injected into the living tissue without waste. Furthermore, since the tip portion of the needle tube is likely to have a rounded structure, it is preferable that it has a closed structure having no small holes.

Using a rounded long needle tube attached to a syringe with a capacity of 50 cc, add epinephrine 0.3
% Xylocaine (lidocaine) solution was infiltrated into the surrounding tissues along the LSV at around 100 ml per limb.
The needle tube has one small hole 2 on one side wall whose tip is within 35 mm, and two small holes 3 and 4 on the opposite side wall, that is, three small holes in total. The infiltration of the xylocaine solution causes the tissue to swell to "water soak" and the skin to become pale due to vasoconstriction. By adopting this TLA method, not only body movements due to bleeding and pain at the time of vein removal are reduced, but also infiltration of a large amount of physiological saline facilitates separation of the vein from surrounding tissues, and vein removal can be performed smoothly. Further, the analgesic action by the TLA method described above lasts during the operation, on the day of the operation, and on the next day, and almost no arthroscopic drug is required.

１個、対向する側壁に２個の合計３個の小孔を有する。Example 2 Inversion varicose vein removal surgery for SSV In the inversion varicose vein removal surgery of Example 1, a skin incision was made in the lower knee, and epinephrine-added 0.3% xylocaine (lidocaine) solution was used. For injection, epinephrine was added using a long needle tube having a curved portion as described above and having a diameter of 15 G and a length of 15 cm with a rounded tip, which was attached to a syringe with a capacity of 30 cc. 0.
A 3% xylocaine (lidocaine) solution was infiltrated into the surrounding tissues along SSV at around 100 ml per limb. The needle tube has a total of three small holes, one on one side wall with a distal end within 35 mm and two on the opposite side walls.

施例１のＬＳＶに対する内翻抜去と同様に行った。As an inversion stripper for SSV, a bendable silver-plated copper rod having a diameter of 2 mm and a length of 27 mm is joined with a stainless wire having a diameter of 1.2 mm and a length of 45 cm. A vein ligation part is provided on the wire side. The stainless rod can be inserted into a vein and projected from the skin incised in the peripheral portion.
Also, a Babcock is attached to the end of the stainless wire.
A bell-shaped head (extraction head) can be attached so that it can be changed to the law. The inversion of the SSV was performed in the same manner as the inversion of the LSV of Example 1.
