JPH08735A - Tube catheter - Google Patents

Abstract

PURPOSE:To provide a catheter capable of easily penetrating into skin even if the skin is cut small to suppress the invasion to a patient to the least when the connector part is guided out of the patient and securely holding the connector part. CONSTITUTION:A tubular connector part 2 with an inner hollow communicating to the hollow of the tube 1 is fastened to the end part of the tube 1 of the tube catheter. The connector part 2 is provided with a guide part 3 tapered toward the end installed on its end, the tip of the guide part 3 is covered and a protruding plate-like holding part 4 is equipped on the end part. A hole 5 and a protrusion are made on the end part of the holding part 4 and a ring type ditch 7 is formed on the outer periphery of the connector part 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved tube catheter.

[0002]

2. Description of the Related Art As an example of a tube catheter, a surgical drain tube is mainly used for drainage after a surgical operation and is left in the body. Separately, a method is employed in which a small incision is made in the skin, forceps are inserted through the small incision, the connector of the drain tube inside the body is grasped by the forceps, and the skin is guided from the small incision site to the outside of the body. However, since the connector of the conventional surgical drain tube has a cylindrical shape, when it is guided from the inside to the outside of the body, not only is it not easy to pass through the skin, but also it is not easy to securely grasp with forceps. was there.

[0003]

An object of the present invention is to facilitate the in vitro guidance of a tube catheter and to ensure that it can be grasped by forceps, and to safely perform the procedure within a short time and It is to reduce the invasion of. Surgery, despite the effort of the practitioner, is not a heavy burden on the patient, and the fact that the procedure is safe and reliable in each and every step of the procedure means that the physical burden on the patient is ultimately high. Is reduced that much,
Naturally, it can have a significant impact on the prognosis. On the other hand, even on the practitioner's side, the fact that each of the treatment processes can be performed easily, safely and reliably means that the mental and physical burdens are reduced accordingly, and the surgical operation has a very difficult main purpose. Even so, it will lead to a margin to deal with this.

[0004]

[Means for Solving the Problems] To solve the above problems, in the case where a connector portion provided at an end portion of a tube catheter is formed into a conical shape and the tube catheter is guided outside the body through a small incision provided in the skin. It is possible to minimize the resistance of. In addition, when gripping the connector portion with forceps, a grip portion is provided that enables this securely and reliably, and a thin plate shape is provided so that the grip portion does not increase its resistance when passing through a small skin incision. A hole was bored in this, and / or a protrusion was provided so that the tip of the forceps was engaged with the hole or protrusion so that the grasping did not come off when the tube catheter was guided outside the body.

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view showing the outline of the embodiment, and FIG. 2 is FIG.
A sectional view taken along the line A, and FIG. 3 are partial explanatory views showing an example of the grip portion. The tube (1) is a tubular catheter tube made of synthetic resin or the like, and has a tubular connector portion (2) provided with a cavity (9) communicating with the lumen (8) thereof. In the first embodiment, a guide portion (3) having a substantially conical shape is provided at the end portion of the connector portion (2) in the distal direction to reduce the resistance when guiding from a small incision in the skin to the outside of the body. Configured to do so. Whether the end of the guide (3) is closed or left open is a matter of design. Further, the conical shape of the guide portion (3) is appropriately selected depending on the size of the diameter of the connector portion, the convenience of gripping with forceps, and the like. In another embodiment, in order to facilitate grasping with forceps and facilitate the operation, the connector portion (2) is covered with the tip of the guide portion (3), and a plate-like grasping portion (4) projecting from this is covered. To provide. In the case where this is difficult only with the guide part (3) because it is necessary to cover the tissue and make the incision site different in the thickness of the tissue passing through when guiding it outside the body, and to increase the force gripped by the forceps,
This is to ensure the grip and to prevent the resistance from increasing as much as possible. Therefore, in order to make gripping more surely and easily, one or a plurality of holes (5) or protrusions (6) are provided at the end of the gripping part (4) so that they can be engaged with the forceps. The shape of the grasping portion (4) should be selected in consideration of the reduction in human tissue resistance and the ease of grasping, such as the thickness and width of the plate and whether the tip has an acute angle. Similarly, when the tube (1) is thick, the shape of the connector portion (2) may be designed so that the end portion is thin and the resistance of human body tissue is small. By the way, after the guide of the tube catheter is completed, the guide part (3) and the like should be excluded in order to obtain the original function of the connector part (2), but at that time, cut with scissors or the like. However, according to the present invention, the connector part (2) is provided so that the guide part (3) can be easily broken outside the body.
A circular cut (7) was provided on the outer peripheral wall of the.

[0006]

According to the present invention, the surgical drain tube can be easily guided to the outside of the body, the time required for the entire operation can be shortened, and the prognosis of the patient can be ensured. In addition, the mental and physical burden on the practitioner can be reduced, and the patient can concentrate on the original surgery.
