Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a surgical knot exercising device for mastering knot tying in a surgical operation.

(Prior Art) Generally, it is well known that a dummy is used for repetitive practice in order to acquire and improve the technique. Also in the medical field, instruments for learning how to tie surgical threads are used in the field of surgery. When tying the surgical thread, it is assumed that the surgical field (the incised affected area) is narrow and deep, but a hook is simply prepared, and the surgical thread is practiced to be tied to the hook.

(Problems to be solved by the device) However, since there are blood transfusion and bypass tubes in the actual surgical field, the movements of the hands and fingers for knotting are delicate, and moreover, it is only necessary to tie the surgical yarn. Since it is also necessary to take care not to press the tube without doing so, conventional instruments have been required to be more practical than conventional ones.

An object of the present invention is to provide a surgical thread knot training device that can assume various conditions according to the above requirements.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a tubular body 1, a lateral member (1a) integrally attached to the inside of a lower portion thereof, and a lateral member (1).
a) a hook member 3 fixed to the upper surface of the lateral member (1a), and a tubular member 1;
A tube 4 made of silicon rubber or the like, which is inserted into a through hole 1d formed in the wall surface of the cylindrical body 1 and is arranged across the inside of the tubular body 1.
It consists of and.

(Operation) With the above configuration, the present invention allows not only the hook member 3 to be tied with the surgical thread (T) but also the practice of tying the tube 4 without affecting the tube 4, and the practice of binding the tube 4 together. .

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS.

In the figure, a tubular body 1 forming an operation field has a bottom portion 1a which is a lateral member and a skirt portion 1b, and a projection 1c which fits into a mounting recess 2a of a suction cup 2 which is an adsorption member is provided at the center of the lower surface of the bottom portion 1a. Has been formed. The suction cup 2 fitted and attached to the protrusion 1c is partially covered by the skirt portion 1b. A hook member 3 is screwed to two places on the bottom portion 1a, and a tube 4 made of silicon rubber or the like is internally passed from a hole 1d formed in the peripheral wall to a different hole 1d across the center of the inner wall. Have been stretched over. This number may be reduced or increased. Further, the tube 4 located at the upper part of the tubular body 1 passes through a plurality of annular holes 1d and is attached along the peripheral wall.

By using this device, in addition to practicing the operation of tying the surgical thread T with the hook member, the operation can be performed without pressing the tube 4, and the tube can be bound by simulating it as a blood vessel. The surface fixed by the suction cup 2 is not limited to the horizontal surface and may be fixed anywhere.

The tubular body 1 does not have to have a circular cross section as shown in the embodiment, and if the bottom portion 1a can support the hook member 3 and the suction cup 2,
An elongated plate may be provided in the center. Further, the cylindrical body 1 may be made of any material, but if it is made of plastic, post-processing is easy and the positions of the holes can be changed. Also, if you make it transparent, you can check the operation from the side,
Making it opaque makes it more practical.

(Effect of the Invention) Since the present invention is configured as described above, since the tube is located above the hook member, a more practical practice of tying the surgical thread can be performed. Further, since the suction member is attached to the lower portion of the tubular body, the tubular body is in a state of slightly moving, which is more practical.
