[0027] Hereinafter, embodiments disclosed in the present disclosure will be described in detail with reference to the accompanying drawings.

[0028] FIG. 1 is a side view for explaining an implant surgical instrument for sinus lift technique using hydraulic pressure according to an embodiment of the present disclosure, and FIG. 2 is an internal cross-sectional view of the extrusion control unit shown in FIG. 1.

[0029] As shown in FIG. 1 and FIG. 2, the implant surgical instrument for sinus lift technique using hydraulic pressure 10 according to the embodiment of the present disclosure may include a body portion 100, a fastening portion 200, and a connection portion 300. In this case, the body portion 100, the fastening portion 200, and the connection portion 300 may include a through hole 400 therein when formed integrally, but is not limited thereto.

[0030] The body portion 100 may include the through hole 400 therein, and an outer side thereof may include a flat portion 120 and a compatible component coupling portion 140.

[0031] The flat portion 120 may be formed in a cylindrical shape, and the outer surface may be formed flat.

[0032] The compatible component coupling portion 104 may be integrally connected with the flat portion 120, and an adapter 500 may be coupled to the outer surface.

[0033] In the present embodiment, the compatible component coupling portion 140 may include a coupling portion 142 formed of at least one surface and a coupling connection portion 144 connecting the coupling portion 142. In this case, although the coupling portion 142 is disclosed as two, the present disclosure is not limited thereto.

[0034] Depending on the embodiment, the coupling portion 142 may be coupled to a screw, but is not limited thereto, and may be coupled to a ratchet.

[0035] In the present embodiment, at least one surface of the compatible component coupling portion 140 is disclosed in a square shape, but is not limited thereto.

[0036] The fastening portion 200 is connected to one side of the body portion 100 and has a predetermined length, and a screw thread is formed on the outer circumferential surface thereof to be screwed into an implant hole 3 of a perforated maxilla 2. That is, the fastening portion 200 may be integrally connected with the flat portion 120 of the body portion 100.

[0037] In this case, the screw thread of the fastening portion 200 is screwed into the implant hole 3, so that it can be inserted and extracted into the implant surgical instrument for sinus lift technique using hydraulic pressure 10.

[0038] The fastening portion 200 may be formed such that the outer circumferential surface gradually decreases from a surface connected to the flat portion (120) (i.e., an upper part) to a lower part. That is, the fastening portion 200 may be formed to be inclined downward.

[0039] A diameter of a top surface of the fastening portion 200 may be larger than a diameter of a bottom surface of the fastening portion 200.

[0040] For example, the diameter d1 of a top surface of the fastening portion 200 may be 4.0 mm, the diameter d2 of a middle surface may be 3.5 mm, and the diameter d3 of a bottom surface may be 3.1 mm when a fixture diameter of the implant surgical instrument for sinus lift technique using hydraulic pressure 10 is 4.0 or 4.5.

[0041] Furthermore, the diameter d1 of the top surface may be 4.9 mm, the diameter d2 of the middle surface may be 4.4 mm, and the diameter d3 of the bottom surface may be 3.9 mm when the fixture diameter of the implant surgical instrument for sinus lift technique using hydraulic pressure 10 is 5.0 or 5.5.

[0042] In addition, the diameter d1 of the top surface may be 5.6 mm, the diameter d2 of the middle surface may be 5.3 mm, and the diameter d3 of the bottom surface may be 4.8 mm when the fixture diameter of the implant surgical instrument for sinus lift technique using hydraulic pressure 10 is 6.0 or 7.0.

[0043] The fastening portion 200 formed to be inclined downward as described above may be screwed into the implant hole 3 of the perforated maxilla 2, so that water supplied to the maxilla 2 can be prevented from leaking. In addition, by preventing the water supplied to the maxilla 2 from leaking, it is possible to keep the hydraulic pressure inside the maxillary sinus 1 uniform.

[0044] The connecting portion 300 may be connected to and formed on other side of the body portion 100 and may include at least one locking projection 320. That is, the connection portion 300 may be integrally formed with the compatible component coupling portion 140 of the body part 100.

[0045] In the present embodiment, although the locking projection 320 of the connection portion 300 is disclosed as two, the present disclosure is not limited thereto, and the connection portion 300 may include one or more locking projections 320.

[0046] The connection portion 300 having such a structure may be connected to a water supply member 4.

[0047] The water supply member 4 may include a connection member formed of a rubber material that is coupled to the locking projection 320 of the connection portion 300, a connection pipe 40 leading from the connection member, and a push rod 44 for pushing water filled in a syringe 42. By pressing the push rod 44 of the syringe 42, the water filled in the syringe 42 is supplied to the implant surgical instrument for sinus lift technique 10 through the connection pipe 40, and since the hydraulic pressure of the supplied water lift the sinus membrane, it is possible to perform the sinus lift easily and conveniently without damaging the inner membrane.

[0048] The through hole 400 may include a first through hole 420 disposed in the body portion 100 and the fastening portion 200, and a second through hole 440 disposed in the body portion 100 and the connection portion 300.

[0049] According to the embodiment, the second through hole 440 may be fastened to the water supply member 4 in the form of a screw, but is not limited thereto. Since the second through hole 440 and the connection pipe 40 of the water supply member 4 are fastened in the form of a screw, separation can be prevented and water leakage can be prevented.

[0050] The first through hole 420 and the second through hole 440 may be formed in a cylindrical shape, but are not limited thereto.

[0051] A diameter of the first through hole 420 may be smaller than a diameter of the second through hole 440, but is not limited thereto. In this case, the diameter of the first through hole 420 may be smaller than a diameter of the fastening portion 200, and the diameter of the second through hole 440 may be smaller than a diameter of the connection portion 300.

[0052] Due to the difference in diameter of the through hole 400 having a structure having a larger diameter of the second through hole 440 disposed in the connection portion 300 into which water is injected than the diameter of the first through hole 420 of the fastening portion 200 disposed in the maxillary sinus, water can quickly moves to the maxillary sinus, and only a desired part can be quickly lifted.

[0053] FIG. 3 is a side view for explaining an implant surgical instrument for sinus lift technique using hydraulic pressure according to another embodiment of the present disclosure, and FIG. 4 is a view for explain an implant surgical instrument for sinus lift technique using hydraulic pressure shown in FIG. 3, and FIG. 4(a) is a view for explaining the adapter, and FIG. 4(b) is a view for explaining the coupling state of the adapter and the implant surgical instrument for sinus lift technique using hydraulic pressure.

[0054] As shown in FIG. 3 and FIG. 4, the implant surgical instrument for sinus lift technique using hydraulic pressure 20 may include an adapter 500 coupled to the outside of the body portion 100.

[0055] Except for the adapter 500 shown in FIG. 3 and FIG. 4, it may have the same characteristics as the implant surgical instrument for sinus lift technique using hydraulic pressure 10 shown in FIG. 1 and FIG. 2.

[0056] In FIG. 3 and FIG. 4 below, detailed descriptions of content overlapping with those described in FIG. 1 and FIG. 2 may be omitted, and different points may be mainly described. Accordingly, components that perform the same functions as those of the implant surgical instrument for sinus lift technique using hydraulic pressure 20 shown in FIG. 3 and FIG. 4 are denoted by the same reference numerals as in FIG. 1 and FIG. 2, and detailed descriptions thereof will be omitted.

[0057] The adapter 500 may include an insertion hole 520 corresponding to the shape of the outer surface of the body portion 100 so as to be coupled to the outer surface of the body portion 100 therein, and at least one outer circumferential groove 540 formed on the outer circumferential surface.

[0058] The insertion hole 520 may be formed in a square shape corresponding to the outer shape of the coupling portion 142. That is, the insertion hole 520 may be formed in a square shape corresponding to the shape of the compatible component coupling portion 140, but is not limited thereto. In particular, it may be formed to correspond to the shape of the coupling portion 142 of the compatible component coupling portion 140.

[0059] The outer circumferential groove 540 may be formed in a curved shape, but is not limited thereto.

[0060] The operation of the implant surgical instrument for sinus lift technique using hydraulic pressure 10 of this structure is as follows. FIGS. 5A, 5B are a view for explaining a state of use of an implant surgical instrument for sinus lift technique using hydraulic pressure according to an embodiment of the present disclosure, and FIG. 5A is a view for explaining a state before injecting water into the sinus, and FIG. 5B is a view for explaining a state in which water is injected into the sinus.

[0061] First, as shown in FIGS. 5A, 5B, in the method of sinus lift using hydraulic pressure, the implant surgical instrument for sinus lift technique using hydraulic pressure 10 is inserted into the implant hole 3 formed to match the diameter of the implant, and inserted to the maxilla 2 under a periosteum of the maxillary sinus 1 so as not to reach the periosteum (not shown) in the maxillary sinus 1 (See FIG. 5A). Then, the water supply member 4 is connected to the implant surgical instrument for sinus lift using water pressure 10, and the periosteum of the bottom of the maxillary sinus 1 can be lifted using the hydraulic pressure generated by water (see FIG. 5B).

[0062] Moreover, due to the difference in diameter of the through hole 400 disposed in the implant surgical instrument for sinus lift technique using hydraulic pressure, water quickly move to the sinus and quickly lift only the desired part. That is, the diameter of the second through hole 440 disposed in the connection portion 300 into which water is injected is formed larger than the diameter of the first through hole 420 of the fastening portion 200 disposed in the sinus, and thus, by pressing the push rod 44 of the syringe 42, the water filled in the syringe 42 passes through the paths of the connection pipe 40, the connection portion 300, the body portion 100, and the fastening portion 200, and the periosteum of the bottom of the sinus 1 can be lifted easily and conveniently without damaging the inner membrane.

[0063] The steps of a method or algorithm described in connection with the embodiments of the present disclosure may be implemented directly in hardware, implemented as a software module executed by hardware, or a combination thereof. Software may also reside on random access memory (RAM), read only memory (ROM), erasable programmable ROM (EPROM), electrically erasable programmable ROM (EEPROM), flash memory, hard disk, removable disk, CD-ROM, or any type of computer-readable recording medium well known in the art to which the present disclosure pertains.

[0064] In the above, embodiments of the present disclosure have been described with reference to the accompanying drawings, but those of ordinary skill in the art to which the present invention pertains will be able to understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential features thereof. Therefore, the embodiments described above are illustrative in all respects and should be understood as non-limiting.
