Description

[Detailed Description of the Invention] The present invention relates to a new flexible suction tube that is capable of smoothly suctioning and discharging drainage fluid that accumulates in an affected area mainly during brain surgery and other surgical operations.

Conventionally, tubes that were simply flexible and elastic were used, so when suspended using a supporter, etc., they would swing around, making it difficult to suction fluid from the affected area. It had some serious flaws.

Furthermore, even when the tube is desired to be positioned far from the hand during surgery, the tube tends to come closer to the user due to its elasticity and cannot be fixed at a far position without using another support, which is a hassle.

The present invention has been devised in view of these points, and its contents will be explained below based on the illustrated embodiments.

Reference numeral 1 denotes a flexible tube body made of silicone resin or the like, and is composed of a first tube 2 with a small diameter, a second tube 3 with a medium diameter, and a third tube 4 with a large diameter.

Reference numeral 5 indicates a through hole portion of the first tube 2, and reference numeral 6 indicates a bendable wire embedded in the first tube 2, which is made of stainless steel wire.

By embedding the wire 6, when the first tube 2 is bent appropriately, it can be bent into a desired shape and the bent state can be maintained, making it easier to perform surgery.

7 is the suction tip of the first tube 2, and the tip 6A of the wire 6 is retracted by a distance l to make it flexible so as to bring it into direct contact with the affected area 8. 1
Reference numeral 1 denotes an extension of a wire 6 protruding from the first tube 2, and is shielded with silicone resin or the like.

9 is a large diameter wire embedded in the second tube 3, which is thicker than the wire 6.

This large diameter wire 9 is also made of stainless steel wire, and the second tube 3 is appropriately bent from the root to strengthen the waist of the entire tube body 1 and maintain its bent position.

Reference numeral 10 denotes a through-hole portion of the second tube 3, which integrally connects the base portion 12 of the first tube 2 and an extension portion 11 shielded with silicone resin.

Next, the manner of use of the product of the present invention having the above configuration will be explained.

Support the tube body 1 with appropriate metal fittings (not shown)
After attaching the suction tip 7 to the affected area 8, the second tube 3 and the first tube 2 are appropriately bent and deformed.

At that time, the first tube 2 and the second tube 3 maintain their appropriately bent and deformed shapes and maintain their positions.

In this state, the operator or the like can easily perform the surgery and can continuously aspirate the drained fluid from the affected area 8 using a suction pump (not shown).

Therefore, the present invention has the above-mentioned structure and operation, and in particular, the metal wire 6 is embedded in the first tube 2 and the extension part 11 connected thereto, and the metal wire 6 is embedded in the extension part 11. Since a large-diameter metal wire 9 is embedded in the second tube 3 so as to be partially parallel to the metal wire 6, the tube remains intact even if the second tube 3 is bent appropriately from the base. Because the waist is strong relative to the entire body 1,
The desired bent shape position can be stably maintained without the need for any kind of support, making it easier to perform surgery, etc., and in particular, the lumbar region can also be used to aspirate drainage fluid from the affected area in a limited area. This can be done smoothly and reliably by improving the stability of the process. In addition, the tip 6A of the wire 6 is variably set so that it can be retracted by an appropriate distance l depending on the shape of the affected area 8 that it directly contacts, rather than the suction tip 7, so the suction tip 7 can be made into a different shape. It has great practical effects, such as being able to have flexibility as appropriate without having to change it or add a separate member, and there is no risk of damaging the affected area 8.
