Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a high-pressure cooling device for a surgical guide used in a digital implant surgery,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cooling device applied to a surge guide used in a digital implant surgery, and more particularly, to a surgeon's guide for effectively performing a drilling operation on a gum bone, To a pressure cooling apparatus for a surge guide of a digital implant surgery.

A dental implant (hereinafter simply referred to as an "implant ") is also called an artificial tooth or a third tooth. That is, the implant is a dental treatment method that restores the function of a natural tooth by implanting a biocompatible material such as a titanium-based metal artificial tooth on a portion of a tooth having a defect or a gum bone of a tooth extracted from the tooth, Or an artificial tooth itself.

In recent years, due to the development of CBCT (Cone Beam CT) and intra-oral scanner technology in the dental field, all information necessary for surgery has already been determined prior to surgery, and dental implant surgery The depth, and the direction of the drilling can be adjusted to a level that can be adjusted by using a surge guide (hereinafter, simply referred to as a surge guide).

In contrast, digital implant surgery using a surgeon guide has been widely used one day. This type of digital implant surgery is different from conventional surgery in that a surgical operation is performed by cutting the gum with a surgical knife and peeling the gum and observing the lower gum bone directly , The gums are not incised, and only a hole having a diameter of about 3 to 4 mm is pierced through the gums, and then the process proceeds in a flapless manner.

Despite the many advantages of digital implant surgery using a surgeon guide, there is one weak point: it does not detach the gums, and because the surgeon guides the surgical site, It is extremely difficult for the saline solution to reach the drill site and the alveolar bone site, which causes the heat generated in the alveolar bone during surgery to increase the possibility of failure of alveolar bone necrosis or osseointegration of the implant. Studies have shown that bone tissue cells can survive for one minute at 44-47 ° C and that bone turnover can damage bone regeneration if they are passed.

Since the heat generation of the alveolar bone is a serious problem, various measures have been proposed to solve this problem. For example, a method has been proposed in which saline is sprayed directly onto a perforated alveolar bone without drilling in the middle of drilling, which has a fundamental limitation that the heat itself generated during the drilling process can not be blocked. Alternatively, a method of supplying a saline solution by opening a part of the side surface of the surge tank guide has been proposed. However, this leads to a deterioration of the guiding performance, and even a low-speed drilling without water supply has been introduced. However, This is also not a solution as long as strong drilling for a long period of time does not lead to deadly bone damage.

Korean Registered Utility Model No. 20-0482232 (Registered on December 27, 2016)

An object of the present invention is to provide a pressurizing and cooling apparatus for a surge guide capable of effectively cooling the heat generated in a tooth placement part even when a drilling operation is performed on an alveolar bone using a surge guide.

The present invention relates to a pressurized cooling apparatus for a surge tank, comprising a pressurized air supply source for supplying pressurized air, a first inlet and a second inlet communicating with an inner space at one end, A first pressurized air line connecting the pressurized air supply source and a first inlet of the mixing chamber, and a second pressurized air line connecting the pressurized air supply source and the first inlet of the mixing chamber, A second pressurized air line connecting the pressurized air supply source and the sealed space of the saline solution container; And a pressurized saline solution line connecting the saline solution of the saline solution container and the second inlet of the mixing chamber.

The pressure regulating mechanism may be provided on the first pressurized air line and the pressurized saline solution line. For example, the pressure regulating mechanism may be a clamp for regulating the fluid.

The surgeon guiding system for dental implant surgery can be constituted together with the surge guide in the pressurizing and cooling apparatus for the surge guide of the present invention having the above-described structure. In the system, the surge guide is a drilling operation And a mixing chamber of the pressurizing and cooling device is inserted and fixed in the injection hole.

Here, the injection hole may be formed with a step that serves as a stopper so that the mixing chamber is not protruded toward the tooth placement target portion.

The pressurizing and cooling apparatus of the present invention having the above-described configuration does not merely spray only the saline solution but pressurizes the saline solution with the compressed air mixed. Therefore, according to the embodiment, It is possible to obtain a cooling effect that is enhanced several times as compared with the case where the saline solution is injected through the drill or through the surge guide or on the side of the surge guide.

Accordingly, the present invention enables the implant surgery to be performed without concern for alveolar bone damage, and the modification and thermal damage of alveolar bone cells are suppressed, which ultimately contributes greatly to the success rate of the implant surgery.

The present invention relates to a cooling device (100) applicable to a surgical guide (200) for use in dental implant treatment, and particularly relates to a cooling device (100) (Hereinafter, simply referred to as "pressurized cooling apparatus") for a tooth-implant surge guide capable of effectively cooling through mutual synergism of pressurized saline solution 142 and air. By applying the pressurizing and cooling apparatus 100 to the digital implant surgery, the implant operation can be performed safely without fear of bone damage, and as a result, the success rate of the implant surgery can be greatly increased. Hereinafter, the pressurized cooling apparatus 100 of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram showing the overall configuration of a pressurized cooling apparatus 100 according to the present invention.

The pressurized cooling apparatus 100 is composed of a plurality of lines connecting the pressurized air supply source 110, the saline solution container 140, and the mixing chamber 120 to each other.

The pressurized air supply source 110 means an apparatus or means for supplying pressurized (compressed) air. The air compressor may be used as the pressurized air supply source 110. In particular, since the present invention is used for a dental implant, pressurized air may be supplied from a compressed air supply end of a unit chair of a dental hospital . The pressurized air supply source 110 may be provided with an air regulator 112 to adjust the pressure to an appropriate level.

The mixing chamber 120 forms a terminal in which the pressurized air and the saline solution 142 are combined and sprayed together. One end of the mixing chamber 120 is provided with a first inlet 124 and a second inlet 126 communicating with the internal space 122. At the other end of the mixing chamber 120, (128). It is noted that the first and second inlets 124 and 126 do not limit and refer to any particular structure (e.g., a connecting nipple), and more widely pressurized air and saline 142 may be present in the mixing chamber 120 And means a passage into the inner space 122 (see the embodiment of FIG. 2).

The saline solution container 140 refers to a container for containing sterilized, sterilized saline solution 142. The saline solution 142 occupies a part of the entire space of the saline solution container 140, and the remaining part of the saline solution 142 forms the closed space 144. That is, the saline solution container 140 receives the pressure supplied from the pressurized air supply source 110 and can be sealed (capable of being opened for saline supply) so that the pressure therein can rise, and sufficient It is necessary to have pressure resistance.

The pressurized air supply source 110, the saline solution container 140, and the mixing chamber 120 are connected to each other through a plurality of lines. The first pressurized air line 130 connects the pressurized air supply source 110 and the first inlet 124 of the mixing chamber 120. The second pressurized air line 132 connects the pressurized air supply source 110 and the enclosed space 144 of the saline solution container 140 and the pressurized saline solution line 134 connects the saline solution 142 of the saline solution container 140, And the second inlet (126) of the mixing chamber (120).

The first pressurized air line 130 is a line for directly supplying the compressed air supplied from the pressurized air supply source 110 into the mixing chamber 120. The second pressurized air line 132 is a line for supplying compressed air to the enclosed space 144 of the saline container 140 to apply pressure to the saline 142 therein and the pressurized saline solution line 134 is a line Is a line connecting the brine 142 pressurized by the compressed air of the pressurized air line 132 to be pushed into the mixing chamber 120.

Thus, the pressurized air is directly supplied to the mixing chamber 120 by the pressurized air supply source 110, and the saline solution 142 is indirectly pressurized by the pressurized air to be supplied to the mixing chamber 120, And the saline solution 142 are mixed in the inner space 122 of the mixing chamber 120 and are strongly ejected through the injection hole 128.

2 shows that at least a portion of the first pressurized air line 130 and the pressurized saline solution line 134 are connected to the first pressurized air line 130 while the pressurized saline solution line 134 forms the inner tube 134 ' 130 "). If the two lines (hoses) are elongated separately, it is inconvenient and uncomfortable to use, and the concentric double pipe line as shown in Fig. 2 is very helpful in solving such a problem. In addition, since the pressurized saline solution line 134 through which the saline solution 142 flows is disposed in the inner tube 134 ', the outer tube 130' seals the pressurized saline solution when there is some leakage in the pressurized saline solution line 134 It is possible to further reduce the concern that the pressurized saline solution 142 is sprayed to the surrounding environment.

An embodiment in which the first pressurized air line 130 and the pressurized saline solution line 134 are connected to one end of the mixing chamber 120 when they form a concentric double pipe structure is also shown in FIG. One end of the mixing chamber 120 is formed as an open side and the inner tube 134 'as the pressurized saline solution line 134 is inserted into the inner space 122 of the mixing chamber 120 while the first pressurized air line 130 The first inlet 124 and the second inlet 126 also have a concentric structure by closely fixing the outer tube 130 'on the outer circumferential surface of one end of the mixing chamber 120. Although not shown, various reinforcing structures may be added, such as forming or annularly pressing a plurality of annular projections on the outer circumferential surface of the mixing chamber 120 to enhance the clamping force of the first pressurized air line 130 .

In addition, a spiral structure 123, for example, a spiral protrusion or a groove, which forms a swirling flow, may be formed on the inner peripheral surface of the inner space 122 of the mixing chamber 120. The helical structure 123 promotes the mixing and interaction of the air and the saline solution 142 and provides a rotating speed component when discharged from the spray hole 128 so that the cooling effect of the tooth placement target portion 240 It helps to strengthen.

3 shows an embodiment in which the pressure regulating mechanism 150 is provided in the pressurized saline solution line 134 and the first pressurized air line 130, respectively. The pressure of the air sprayed from the mixing chamber 120 and the pressure of the saline solution 142 can be adjusted through the air regulator 112 as a whole, It is useful to separately provide a pressure regulating mechanism 150 in the pressurized saline solution line 134 and the first pressurized air line 130, respectively.

In the illustrated embodiment, the pressure regulating mechanism 150 is applied with a clamp for controlling fluid. A fluid control clamp is a known technique for controlling the flow rate of fluid by linearly changing the cross-sectional area of a flexible and resilient hose (changing the degree of pressing while moving the roller of the clamp). However, if the fluid control clamp is applied to the concentric double pipe line, the first pressurized air line 130, which is the outer pipe 130 ', may be closed before the pressurized brine line 134, which is the inner pipe 134' , And it is preferable that they are respectively installed in the pressurized saline solution line 134 and the first pressurized air line 130 before they are merged into the concentric double pipe line.

FIG. 4 shows an embodiment in which the pressurizing and cooling apparatus 100 for a surgeal guide according to the present invention having the above-described structure constitutes a surgeal guiding system 10 for dental implant surgery together with a surge guide 200 have.

The surge guide 200 is provided with a guide hole 220 for guiding a drilling operation for dental implant treatment. The surgeon 200 surrounds the tooth placing part 240 on the basis of the three-dimensional data obtained from the mouth cavity of the subject It is an on-site attachment with a profile similar to a mouthpiece made of a fixed profile. However, the surge guide 200 is fixed to the teeth or gums around the subject 240 and does not necessarily have to be an arch that covers the mandible or the maxillary dental arch, and a part of the dental arch It can be made in a short wrapping form. The detailed structure of the surge guide 200 itself can be found in Patent Document 1.

Thus, the surgeon guide 200 has a guide hole 220 for guiding a drilling operation for dental implant treatment. As shown in the cross-sectional view of "AA" in FIG. 5, And a main water hole 230 is formed so as to penetrate toward the tooth placing part 240. Even if the guide hole 220 of the surge guide 200 is formed on the inner circumferential surface of the metal sleeve 210, the height of the sleeve 210 is only about half the height of the surge guide 200, It is not unreasonable to form the through hole 230 so as to bypass the through hole 230.

The mixing chamber 120 forming the end of the pressurizing and cooling apparatus 100 is inserted and fixed in the injection hole 230 of the surge guide 200. That is, the diameter of the injection hole 230 has a diameter and a tolerance such that the mixing chamber 120 can be inserted and fixed by the frictional force. Since the injection hole 230 of the mixing chamber 120 is formed so as to pass through the guide hole 220 and face the tooth placement target portion 240, the injection hole 128 of the mixing chamber 120 is formed in the front . Accordingly, when the pressurizing and cooling apparatus 100 is operated to perform the drilling operation on the alveolar bone, the pressurized air and the saline solution 142 are injected into the to-be-placed object part 240 in a mixed state to cool the alveolar bone. do. When the saline solution 142 is refrigerated and stored in the saline solution container 140 immediately before the implant surgery, a more excellent cooling effect can be obtained.

6 shows an embodiment in which a step 232 acting as a stopper of the mixing chamber 120 is formed in the main injection hole 230 of FIG. When the mixing chamber 120 is excessively inserted and protruded from the main injection hole 230 because the main injection hole 230 passes through the guide hole 220 and is directed toward the tooth placement target portion 240 It may cause interference with the progress of the drill. A step 232 is formed in the injection hole 230 so as to form an inlet diameter corresponding to the outer diameter of the mixing chamber 120 and an outlet diameter smaller than the outer diameter of the mixing chamber 120. When the mixing chamber 120 is inserted, It is possible to prevent the drill from interfering with the mixing chamber 120 with the drill.

As described above, according to the present invention, since the saline solution 142 is sprayed in a state in which the compressed air is mixed rather than simply spraying the saline solution, 240), it is possible to obtain a cooling effect that is enhanced several times as compared with the case where the ordinary water stream is sprayed on the side or side of the surge guide, or through the drill. Accordingly, the present invention enables the implant surgery to be performed without concern for alveolar bone damage, and the modification and thermal damage of alveolar bone cells are suppressed, which ultimately contributes greatly to the success rate of the implant surgery.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit of the invention as set forth in the appended claims. It will be understood that various modifications and changes may be made by those skilled in the art without departing from the scope of the present invention.
