A SURGICAL PRACTICE APPARATUS FOR ANASTOMOSIS

The present invention relates to an instrument for anastomosis practice, and more particularly to an instrument for performing an anastomosis procedure for practicing a procedure of observing an incised microvascular microscope while sewing.

Microvascular anastomosis has been performed for the treatment of ischemic cerebrovascular disease accompanied by reconstructive surgery, transplantation or carotid artery or middle cerebral artery stenosis and prevention of secondary ischemic cerebrovascular disease. Microvascular anastomosis is different from general surgery in that microvascular anastomosis is performed by observing microvessels with a microscope and suturing tissues such as blood vessels, and microvascular suture requires a delicate and skilled procedure.

Therefore, a microvascular anastomist must skillfully suture vascular tissue through long-term training, which is directly related to patient safety problems.

A conventional instrument for training anastomosis practice to assist in microvascular anastomosis training is that a thin sheet of a general rubber material is attached to a support plate arbitrarily. The method of using the above-mentioned anastomotic practice tool is to incise the sheet of the rubber material according to the direction to be sewn, and then to observe the micro-needle with a microscope and then to sew it. However, There are a lot of problems in practice.

On the other hand, practice kits have been used when practicing medicine, veterinary medicine or veterinary medicine for sewing artificial skin, but it is difficult to utilize it for fine suture practice because it is not a microvascular suture.

It is an object of the present invention to provide an instrument for practicing an anastomosis practice which enables more sophisticated operation and fine suture in the practice of suturing a microvascular vessel as described above,

An anastomotic practice tool provided as an embodiment of the present invention is a combination of a first panel part having a structure in which a procedure practice area having a through structure is arranged according to a predetermined pattern and a first panel part, And a pad portion formed of a sheet made of the material.

1 shows a front view of an anastomosis practice instrument according to one embodiment of the present invention.

An anastomosis practice tool 1000 provided as an embodiment of the present invention comprises a first panel part having a structure in which a procedure practice area having a through structure is arranged according to a predetermined pattern, The pad unit 200 may be coupled to the first panel unit 100 and may include a pad unit 200 including a pad 100 and a sheet. Since the procedure area of the first panel unit 100 has a through-hole structure, the pad unit 200 can be exposed to the outside along with the first panel unit 100.

As shown in FIG. 1, the model of the procedure practice area of the through-hole structure formed in the first panel part 100 may be rectangular, circular, or polygonal, but is not limited thereto. In addition, a combination of a plurality of different models can be arranged according to a predetermined pattern. The predetermined pattern may be arranged in 2x2 or 4x1 as shown in Fig. 1, but is not limited thereto.

3 shows an example of a design of an anastomosis practice tool according to an embodiment of the present invention.

The first panel part 100 according to one embodiment of the present invention may be manufactured to have a predetermined size as in the design example shown in FIG. 3, a, b, and c are preferably 1.5 cm, 2 cm, and 8.5 cm, respectively, but are not limited thereto. The anastomotic practice tool 1000 according to an embodiment of the present invention can be manufactured in a compact size because it is used by utilizing a microscope.

The first panel part 100 according to an embodiment of the present invention may be formed of an acrylic plate, a synthetic resin, a paper or a metal, and the pad part 200 may be formed of a sheet made of a material having ductility And the material having ductility may be made of any one of synthetic resin, natural rubber, and latex, but is not limited thereto. That is, the sheet material having the soft material may include a material having properties similar to the blood vessels of the human body.

4 is an exploded view of an anastomosis practice instrument according to one embodiment of the present invention.

The apparatus 1000 for training an anesthesiologist according to the present invention further includes a second panel part 300 formed to have the same structure as that of the first panel part 100. The pad part 200 includes a first panel part 100, And the second panel unit 300, as shown in FIG.

The second panel part 300 of the present invention may be formed of an acrylic plate, a synthetic resin, a paper or a metal like the first panel part 100, but is not limited thereto.

Meanwhile, the pad unit 200 according to one embodiment of the present invention can be replaced by being detached from at least one panel part of the first panel part 100 or the second panel part 300, and can be replaced permanently have.

For example, in the first panel part 100 and the second panel part 300, the male and female parts of the first and second panel parts 100 and 300 are provided at the edges or corners of the first panel part 100 and the second panel part 300, The pad unit 200 can be replaced according to binding and separation. In other words, at the position of the second panel part 300 corresponding to the position of the groove formed at the edge or the corner of the first panel part 100, a protruding part capable of binding with the groove of the first panel part 100 is formed . Accordingly, when the pad unit 200 is placed on the first panel unit 100 and the second panel unit 300 is placed on the first panel unit 100, the male and female of the binding unit provided on the panel units 100 and 300 are fastened to the first panel unit 100 and the second panel part 300. [0051] Therefore, the replacement of the pad unit 200 can be performed by removing the binding members provided on the first panel unit 100 and the second panel unit 300, replacing the sheet of the pad unit 200, 100 and the second panel unit 300 are coupled to each other.

After the first sheet portion 100 or the second panel portion 300 is slid to expose the sheet portion of the pad portion 200, the sheet is separated from the non-slid panel portions 100 and 300, The pad unit 200 can be replaced in such a manner that the panel units 100 and 300 that have been slid back are restored to the original positions by sliding the panel units 100 and 300.

5 shows a grid pattern included in a sheet according to an embodiment of the present invention.

The inclusion of the grid pattern on the sheet according to one embodiment of the present invention has the advantage that the insertion and injection distance to the sheet can be measured when the cut surface of the sheet is sealed with the needle and the seal interval can be maintained constant. The procedure for keeping the suture interval constant is of clinically important significance in that blood leaks during vascular suturing are minimized and a minimum number of sutures can be determined.

In addition, since the grid pattern is formed at a right angle, it is easy to insert or inject the needle because the needle can be sewn at right angles to the cut surface (see Fig. 6 (b)).

More specifically, a needle must be inserted into a portion of the incised sheet paper, for example, three times (about 300 microns) of the thickness of the needle at the time of the sealing practice, because the distance can be measured by a grid pattern. Can be grasped accurately. In addition, the position at which the needle is pulled out from the incision surface after inserting the needle into the incision should also be parallel to the portion where the needle is inserted, and the injection or insertion interval of the needle should be the same with reference to the cross section of the incised sheet. At this time, the grid pattern has the effect of providing a guideline for determining the needle insertion or injection position in anastomosis practice. Therefore, an anastomotic practice tool including a lattice pattern can easily perform an anastomosis practice among the practitioners of an anastomosis procedure, and can improve an anastomosis technique.

In order to improve the efficiency of anastomosis practice using an instrument 1000 for anastomosis practice according to an embodiment of the present invention, a line or a lattice pattern constituting the lattice pattern may be coated with a fluorescent material. Therefore, when observing the grid pattern of the sheet by a microscope, the position of the grid pattern can be easily grasped by the influence of the light emission by the fluorescent substance when the sheet is sewn with the needle, so that injection or insertion of the needle into the grid pattern can be performed more precisely It is possible.

6 (a) shows the size of the grid pattern according to an embodiment of the present invention.

Referring to FIG. 6, the scale 1 corresponds to 1 nanometer (1 nm). The horizontal and vertical lengths of one grid (one side) according to one embodiment of the present invention is 100 microns, and the diameter of the needle used in this case is also about 100 microns. However, a needle having a different needle thickness may be used for each type of anastomosis (for example, different types of anastomosis according to the size of an artery or a vein or an organs in which anastomosis is performed), or an operator's level . Therefore, the spacing of the grid pattern formed on the sheet can have different values for each sheet depending on the type of the anastomosis procedure or the level of the anastomist. That is, the width (spacing of the lattice pattern constituting lines) between the plurality of lines constituting the grid pattern may have different values each having a predetermined size for each sheet.

For example, in order to practice a high-level anastomosis procedure (e.g., an anastomosis procedure between microvessels), a user may be required to have a lattice pattern of densely spaced lines and a finer size Needles can be used. In addition, in order to practice lower-level anastomoses such as a beginner or an introductory person, a sheet having a lattice pattern composed of relatively coarse-interval lines as compared with the advanced level can be used.

In addition, in order to construct an anastomosis practice step by step using the tool 1000 for anastomosis practice according to one embodiment of the present invention, one sheet may include both a plaid pattern and a non-patterned pattern (FIG. 7). FIG. 7 shows an instrument for practicing anastomosis practice including both a plaid pattern and a non-patterned pattern according to an embodiment of the present invention.

FIG. 8 shows an embodiment of the use of an anastomotic practice tool according to an embodiment of the present invention.

In the actual operating room, the practitioner can not perform the operation by adjusting the direction of the surgical site in a direction that is easy to suture. Therefore, it is necessary to practice the method of suturing in various directions. Accordingly, a method for assisting in the practice of suturing of incisions in various directions can be presented by an anastomosis practice tool 1000 according to an embodiment of the present invention. Practices for sewing the incision sheet in various directions using the anastomotic practice tool 1000 will be described with reference to Figs. 8 (a) and 8 (b).

As shown in FIG. 8 (a), a number 1, 2, 3, and 4 are numbered in an operation practice area arranged according to a predetermined pattern in an anastomotic practice tool 1000 according to an embodiment of the present invention, Can be indicated. As shown in FIG. 8 (b), the sheets corresponding to the practice region are cut out at 135 degrees (degrees), as shown in the cutting directions (Nos. 1, 2, 3 and 4) indicated on the panel units 100 and 300 located at the upper end of the pad unit 200 ), 90 °, 180 °, and 45 °.

By practicing suturing of incised incisions in different directions in 1, 2, 3, and 4 number order, it is possible to practice sequentially from the direction of easy suture to the direction difficult to suture. In addition, a left-handed anastomotic practice tool 1000 and a right-handed anastomotic practice tool 1000 can be manufactured. In the left-handed anastomotic practice tool 1000, right-handed use and incision direction may be different.

The sheet according to one embodiment of the present invention may be made of an opaque material, and the opaque material may have a low light transmittance characteristic. The advantage that the sheet is made of an opaque material is that the completeness of the suture can be confirmed through the back surface (FIG. 2) when the suture is completed. In practice, suturing requires that the needle pass through all layers of tissue layers, such as blood vessels. Therefore, in the training process, it is necessary to check whether the tissue has passed through the stitched back face after the anastomosis practice.

Therefore, the practitioner or the user performs an anastomosis procedure (for example, stitching) on the incision sheet for the practice of anastomosis, and conducts a light permeability test by passing light or the like through a sheet made of an opaque material can do. In other words, if the anastomosis practice is performed well, there will be almost no transmitted light. If the anastomosis practice is performed relatively poorly, the light will penetrate through the incised part, so that the success of the anastomosis practice can be grasped easily.

It will be understood by those of ordinary skill in the art that the foregoing description of the present invention has been presented for purposes of illustration and that those skilled in the art will readily understand that various changes in form and details may be made without departing from the spirit and scope of the present invention. will be.
