Surgical instruments for joint surgery of trees {OPERATIVE INSTRUMENT FOR HOLLOW TREATMENT OF TREE}

The present invention relates to a surgical instrument for joint surgery of a tree used in surgery for regenerating trees, and more particularly, to an artificial surgical instrument used for treating a cavity of a tree.

In particular, the present invention relates to a surgical instrument for artificial tree joint surgery, which can not only treat the appearance of a tree using natural objects in a natural state as in the original state, but also maintain the integrity of the cavity.

In general, Korea designated special guns, nominal trees, giant trees, wild trees, and deformed trees as natural monuments and protected trees. Among these trees, loggers often form cavities exposed to the outside by windbreaks.

When the bark is split by the phenomena of phenomenon, the cavity is formed in the form of bulging from the base to the top, or ② when the bark is peeled together when the thick branches are broken, the bulge progresses from the top to the bottom. It is formed in the form of being exposed to the outside, or ③ If the swelling progresses due to a wound of a stem or branch, it is formed inside the tree without being exposed to the outside as it progresses from the top to the bottom.

Cavities, if left untreated, are continuously rotted or damaged by bacteria or pests, killing trees. Therefore, the tree can continue to grow only after the site where the cavity is formed through surgery.

The above-mentioned surgical procedures usually proceed in the order of removal of rot, exposure of the cavity forming layer, insecticide sterilization and antiseptic treatment, cavity filling, waterproofing, artificial bark treatment, and antioxidant treatment. At this time, the cavity is filled with a filler such as epoxy resin, unsaturated polyester, polyurethane or urethane rubber.

However, the surgical operation as described above is made of a material 24 different from that of the tree 10, the filling of the inside of the cavity 12, which is shielded by the artificial bark 22, as shown in FIG. As the 10 is stretched, a space is created between the filling 24 and the inner side of the cavity 12.

Therefore, in the case of the conventional surgical procedure as described above, the rainwater flowing from the branch or the wound of the branch penetrates into the space formed between the filling and the inner surface of the cavity 12, or promotes the over-humidity of the cavity 12 portion or However, there is a problem of facilitating the edge of the cavity 12 while accumulating in the aforementioned space. In particular, conventional surgeries do not evaporate the rainwater absorbed in the above-mentioned space due to the non-breathable fillers 24, so that a humid state is maintained for a long time or softening is promoted more quickly.

In addition, there is a problem that a small size pest enters the space between the filling and the cavity 12.

In particular, the cavity 12 formed in the base portion 19 of the tree 10 is in contact with the ground and organically connected to many branches at the top as shown in FIG. More vulnerable to the problem That is, since the cavity 12 formed in the paper portion 19 is in contact with the ground, the cavity 12 is not only more vulnerable to the above-mentioned problem due to the temperature difference of the ground, but also the rainwater flows in various directions through a plurality of branches formed on the upper portion. More vulnerable to the problem

On the other hand, reference numeral 10a of FIG. 1 is a core part positioned in the center of the tree 10, 10b is a sapwood part located outside the core part 10a, and 10c forms a surface of the sapwood part 10b. It is the shell of the tree (10).

There is also.

Hereinafter, referring to the surgical instrument for the joint surgery of the tree according to an embodiment of the present invention with reference to the accompanying drawings as follows, the attached Figure 3 is a surgical instrument for joint surgery of the tree according to an embodiment of the present invention 4 is a perspective view of the tree, and FIG. 4 is a plan view of the tree shown in FIG.

3, the surgical instrument for joint surgery of the tree according to the embodiment of the present invention shields the cavity 12 of the tree 10 as shown. Such surgical instruments include a shield (SD) that shields the cavity 12 as shown, and a supporter 80 that supports the shield SD in the cavity 12.

The shield SD is composed of a shielding network 50 having a mesh, a fibrous filter 60 and an artificial skin 70 as shown. And, the supporter 80 is composed of a horizontal anchor 82 and cross anchor 84 as shown. Referring to the components of the shield (SD) and the supporter 80 in more detail as follows.

First, in the case of the shield SD, the shielding network 50 is preferably composed of a stainless steel mesh of about 80 mesh excellent in durability and breathability. This screen 50 is secured inside the opening 12a of the cavity 12 as shown. At this time, the shielding net 50 is fixed to the opening portion 12a by a pin-shaped fastener 52 to be described later in a state in which the edge portion is bent as shown by "b" as shown in the incision. Thus, the shielding net 50 shields the opening 12a of the cavity 12 in a ventilated and closed manner.

The filter 60 is composed of a main filter 62 and a sub filter 64 as shown. The main filter 62 is cut in close contact with the shielding network 50 as shown in the cut and directly shields the shielding network 50. In addition, the sub filter 64 overlaps the main filter 62 to shield the shielding network 50 secondly as shown. The main and sub filters 62 and 64 are preferably made of a nonwoven fabric having hydrophilic properties and excellent breathability. In particular, the main and subfilters 62 and 64 are preferably made of a nonwoven fabric made of environmentally friendly fibers such as cotton, viscose rayon, pulp, and the like.

The main and subfilters 62 and 64 are sequentially superimposed on the shielding net 50 as shown and then fixed to the opening 12a of the cavity 12 by means of a fixture 52 described below. Of course, the main and sub-filters 62 and 64 are fixed in a state where the edge portion is bent in the same manner as the shielding net 50.

The sub filter 64 may be applied to the surface of the insect repellent material to prevent the habitat of pests or strains. Of course, the main filter 62 may also be applied to the insect repellent material on the surface. Such insecticides are preferably composed of, for example, pharmaceutical insect repellents such as insecticides and pesticides, or activated carbon having excellent antibacterial and insect repellency while being excellent in dry and dry properties.

Insect repellent and activated carbon may be applied on the subfilter 64 in a mixed state, or alternatively, they may be applied on the subfilter 64 in separate states. Insect repellent and activated carbon may also be applied onto the subfilter 64 in a mixed state with ocher powder or ore powder having dry and functional properties. Ore powder is, for example, elvan, which has toxic neutralization and antibacterial and insect repellent properties, or germanium, which prevents the growth of strains such as mold by its constant temperature ability, or bioceramic having bactericidal effects such as Escherichia coli and Staphylococcus aureus. And the like.

Here, the above-described sub filter 64 may be omitted in some cases. In other words, the subfilter 64 may be selectively applied. Alternatively, the sub filter 64 may be configured in plural. At this time, the plurality of sub-filters 64 is preferably configured in a state in which different insect repellent material is applied.

Artificial skin 70 is integrally coupled to the surface of filter 60 as shown. This artificial cuticle 70 is composed of an inner cuticle 72 and an outer cuticle 74 as shown incision. At this time, the inner skin 72 is attached to the sub-filter 64 in an overlapping state as shown. And, the outer skin 74 is attached to the surface of the inner skin 72 in an overlapping state as shown.

Artificial skin 70 is made of granules 70a of uniform size, as shown enlarged. That is, the inner and outer skin 72, 74 is composed of a plurality of grains 70a. These granules 70a form an aggregate as the viscous curable binder is blended into the same body as shown enlarged. At this time, as the granules 70a are formed to have a uniform size, as shown in the enlarged form, the air holes AH are formed in the gaps between the gaps.

The granules 70a are preferably made of an organic material, and more preferably made of an environmentally friendly material such as cork, natural latex or gum arabic.

The binder is preferably composed of, for example, an epoxy cured into a solid phase in a viscous gel state. Such an epoxy is more preferably mixed with a solvent such as acetone for controlling the viscosity. This binder adheres the aggregate of organic grains 70a to the surface of the above-described subfilter 62 by its viscosity. In other words, the artificial skin 70 is attached onto the subfilter 62 by a binder.

Here, the above-described inner skin 72 is composed of an aggregate of grains 70a composed of the grains 70a and the binder described above. In addition, the outer skin 72 described above is configured in the same manner as the inner skin 72, except that the pigment is further added to the inner skin 72. Thus, the outer epidermis 72 expresses a different color than the inner epidermis 72. The outer skin 72 is preferably composed of a color similar to the outer skin of the tree 10 by the pigment, or a color causing natural harmony with the tree 10.

The inner skin 72 may be omitted when forming the outer skin 74 thickly. That is, the artificial cuticle 70 may be composed of only the outer skin 74.

Meanwhile, as described above, the supporter 80 supports the shield SD through the plurality of horizontal anchors 82 and the cross anchors 84 fixed to the inside of the cavity 12 so as to cross each other. In this case, the horizontal anchor 82 and the cross anchor 84 may be bound to each other by the binding hole 89 as shown in the cross section. The binding port 89 may be configured of a tie band for binding a metal wire or an electric wire.

As shown in the horizontal anchor 82, one end is fixed to the inside of the cavity 12, the other end is fixed to the shield (SD). Therefore, the horizontal anchor 82 supports the inside of the shield SD in the cavity 12. This horizontal anchor 82 may be composed of a stud bolt (computer screw) as shown. In addition, the horizontal anchor 82 may have the washer 88 and the nut 86 fixed to the other end, such that the other end is firmly fixed to the shield SD.

The cross anchors 84 are fixed to the inside of the cavity 12 in a state where they cross with the horizontal anchors 82 while being horizontal as shown. The cross anchor 84 is composed of stud bolts in the same way as the horizontal anchor 82 described above, and supports the horizontal anchor 82 through a portion intersecting with the horizontal anchor 82. Therefore, the cross anchor 84 prevents the bending deformation of the horizontal anchor 82. Of course, the cross anchor 84 may be omitted when the size of the cavity 12 is narrow so that only the horizontal anchor 82 can sufficiently support the shield SD. In other words, the cross anchor 84 is an element to be selectively applied.

On the other hand, the fabric 60 and artificial skin 70 may be provided with a reinforcing net 90 in close contact with each other as shown. The reinforcing net 90 is preferably composed of a stainless steel mesh of about 20 mesh smaller than the shielding net 50 described above.

The reinforcing net 90 is attached to one side of the artificial skin 70 in one body. The reinforcing net 90 damps the elastic force of the artificial skin 70 stretched by the temperature difference while shielding one side of the artificial skin 70 to allow ventilation. That is, the reinforcement net 90 serves as a reinforcing bar applied to the concrete structure. Therefore, the artificial skin 70 is reinforced with thermal stress by the reinforcement net (90).

Here, the reinforcing net 90 is fixed to the opening 12a by the fastener 52 described later after the edge portion is bent in the same shape as the edge of the shielding network 50 described above.

Referring to Figure 4, the fastener 52 may be composed of a member such as a pin, nail or screw as shown. The fastener 52 is sequentially fastened through the bent edge of the overlapping shielding net 50 and the fabric 60 and the reinforcing net 90 as shown in the fastening portion 12a. Accordingly, the fastener 52 firmly fixes the shield SD to the opening 12a.

On the other hand, as shown in the supporter 80, the ends of the horizontal anchor 82 and the cross anchor 84 are embedded in the inner surface of the tree 10 which is located inside the cavity 12 and fixed. Thus, the supporter 80 is fixed horizontally in the air inside the cavity 12.

Referring to Figure 3 attached to the installation and operation of the surgical instrument for joint surgery according to the embodiment of the present invention configured as described above are as follows.

As shown, the surgical instrument for joint surgery of the tree according to an embodiment of the present invention is installed as the support (80) is preferentially installed on the tree 10, the shield (SD) is installed. The supporter 80 is removed from the decay portion formed in the cavity 12, the opening 12a of the cavity 12 is exposed, and after the process of disinfection and antiseptic treatment is completed horizontally inside the pupil 12 Installed in a state. At this time, the horizontal anchor 82 and the cross anchor 84 is installed inside the cavity 12 while making a cross state with the washer 88 mounted at the end of the cavity 12. In addition, the horizontal anchor 82 and the cross anchor 84 are cross-linked by the binding holes 89. Thus, the horizontal and cross anchors 82 and 84 are firmly fixed in the crossed state.

The shield SD is installed in the opening 12a of the cavity 12 after the installation of the supporter 80 is completed. Shield (SD) is a shield (50), the filter 60 consisting of the main filter 62 and the sub-filter 64, and the reinforcing network 90 is sequentially overlapped by the opening portion (12a) by the fixture 52 It is fixed to). In this case, the shield SD is fixed to the opening 12a in a state in which a hole (not shown) through which the horizontal anchor 82 penetrates the shielding net 50, the filter 60, and the reinforcing net 90 is formed. Therefore, the shield SD exposes the other end of the horizontal anchor 82 through the hole. The shield SD is provided with an artificial skin 70 on the sub filter 64 of the filter 60 in a state where the other end of the horizontal anchor 82 is exposed.

 On the other hand, the operator mixes the organic granules (70a) of uniform size made of cork to the epoxy-based binder added with acetone, and then aggregates (mixtures) of the granules (70a) forming a lump to the sub-filter 64 To form an inner skin 72. When the formation of the inner skin 72 is completed, the worker adds a pigment of a desired color to the remaining mixture in which the granules 70a and the binder are mixed and then remixes, and then internally aggregates the remixed granules 70a. The outer skin 74 is formed by attaching to the surface of the skin 72. Thus, the shield SD has an artificial skin 70 composed of an inner skin 72 and an outer skin 74 on the outside.

Here, the outer skin 74 described above makes a beautiful appearance at the outermost side of the shield SD, and substantially plays a role corresponding to the outer skin of the tree 10.

On the other hand, when the curing of the binder forming the artificial skin 70 is completed, the washer 88 and the nut 86 is fastened to the other end exposed to the outside of the shield (SD). Therefore, the horizontal anchor 82 is not only firmly fixed but also firmly supports the shield SD.

The shield SD supported in this way supplies the outside air to the cavity 12 through the air vent AH between the grains 70a constituting the artificial skin 70 as shown in an enlarged view. At this time, the reinforcing net 90 prevents the introduction of pests introduced through the vent hole AH of the artificial cuticle 70 while preventing the deformation of the artificial cuticle 70. Then, the sub-filter 64 coated with the antimicrobial insect repellent material such as activated carbon filters the pests and strains introduced into the air vent (AH). Then, the main filter 64 once again filters the pests and strains in the air passing through the sub-filter 64. Finally, the shielding network 50 blocks the influx of pests in a ventilated state while supporting the filter 60. Therefore, the pest or strain is not introduced into the cavity 12 due to the shield (SD).

On the other hand, the cavity 12 is ventilated in the antibacterial and insect repellent state by the shield (SD) can always maintain a comfortable environment in a dry state. That is, the cavity 12 may immediately discharge the moisture or rainwater introduced through the branch to the outside by evaporation.

In the surgical instrument for joint treatment of trees according to the embodiment of the present invention as described above, the supporter 80 made of a rod such as a stud bolt is installed in a horizontal state in the space of the cavity 12, and the shield (SD) is insect repellent While shielding the opening 12a of the cavity 12 in a ventilated state, the cavity 12 can be kept empty at all times. Therefore, the moisture content of the cavity 12 can be maintained at 18% to 35% or less while preventing the invasion of rot fungi or pests, thereby preventing the expansion of the cavity 12 due to the decay of the cavity 12.

In addition, since the supporter 80 is installed inside the cavity 12 without being installed outside of the tree 10, it does not interfere with the growth portion of the tree 10. Therefore, it is possible to continuously grow a larger portion of the tree 10 of the forest.

In addition, the shielding net 50, the main and sub-filters 62 and 64, the reinforcing net 90, and the inner and outer skins 72 and 74 of the shield SD made of different materials are multi-stepted. And while performing the insect repellent ventilate the inside and outside of the cavity 12 can be more securely protected the tree 10, the cavity 12 is formed.

In particular, the insecticide applied to the sub-filter 64 prevents the access and habitat of fungi or pests, so that the trees 10 can be more safely protected.

In addition, since the inner and outer skins 72 and 74 are predominantly based on granules 70a such as cork, and the outer skin 74 expresses various colors desired by the pigment, it can provide an eco-friendly appearance by hydrophilicity. In addition, the heterogeneity of the shield (SD) can be significantly reduced, and since the air hole (AH) is formed between the grains 70a, excellent breathability can be secured.

Furthermore, since the reinforcing net 90 strengthens the durability of the outer skin 74, the outer skin 74 may be minimized from being cracked or peeled off due to a temperature difference.

In addition, since the horizontal anchor 82 and the cross anchor 84 of the supporter 80 are installed in an intersecting state, they are not only firmly fixed to the cavity 12 by the support force of each other, but also support the shield SD more stably. It is possible to prevent the collapse of the shield SD from disturbance such as wind pressure.

Since the above embodiments are merely illustrative of preferred embodiments of the present invention, the scope of application of the present invention is not limited to the above, and appropriate modifications are possible within the scope of the same idea. Therefore, since the shape and structure of each component shown in the embodiment of the present invention can be carried out by deformation, it is natural that the modification of the shape and structure belong to the appended claims of the present invention.
