Abstract
Description
An improved non-surgical crushing and suction removal device capable of minimizing tissue damage for the removal of calcium deposits in calcific tendinitis
[0001] The present invention relates to an improved non-surgical crushing and suction removal device capable of minimizing tissue damage for the removal of calcium deposits in calcific tendinitis.
[0002] Calcific tendinitis of the rotator cuff is a relatively common shoulder joint disease, although its exact cause is unknown. Duplay first referred to it as 'scapulohumeral periarthritis' in 1872, but in 1934, Codman reported that the disease occurs within the rotator cuff rather than in the subacromial bursa.
[0003] Calcific tendinitis refers to a condition in which calcium deposits form within the rotator cuff through a reactive calcification process, leading to inflammation and causing severe pain. Although the exact cause of calcium deposition within the rotator cuff is unknown, there is no specific relationship with trauma; it is known to be associated with systemic diseases such as diabetes, thyroid disorders, and estrogen metabolism, and there are also claims that it is linked to some genetic predispositions.
[0004] In cases of calcific tendinitis, pain may improve and calcium deposits may be naturally absorbed with the administration of non-steroidal anti-inflammatory drugs (NSAIDs), physical therapy, or steroid injections into the subacromial space; however, if the calcium is not removed, symptoms often recur or pain persists.
[0005] Methods for removing calcium deposits include breaking them up using ultrasound-guided lithotripsy with a needle, or removing them through arthroscopy or open surgery.
[0006] Although surgical removal of calcium deposits within the rotator cuff can be a good treatment method as it significantly reduces pain the next day and often prevents recurrence, it often places a physical, mental, and economic burden on the patient due to the burden of general anesthesia, postoperative pain, and high surgical costs.
[0007] To overcome the disadvantages of such surgical treatment, there is a method to remove calcium deposits using only local anesthesia through ultrasound-guided lithotripsy. However, the results of this lithotripsy often depend heavily on the skill of the operator.
[0008] If the procedure is performed successfully, the calcium deposits should be slowly absorbed within one month; however, if the procedure is not performed properly, the calcium deposits often remain, frequently leading to surgical treatment.
[0009] Therefore, there is a need for a calcium deposit removal device that can remove a large amount of calcium with a high probability while minimizing tendon damage, thereby improving upon the disadvantages of conventional calcification lithotripsy treatment using only simple needles.
[0010] The present invention was devised to solve the aforementioned conventional problems and aims to provide a non-surgical crushing and suction removal device capable of crushing lime and suctioning it while minimizing tissue damage.
[0011] The present invention provides a non-surgical crushing and suction removal device comprising: an insertion guide (100) that is inserted into the human body and provides a passage; and a removal device (200) that is introduced into the human body through the insertion guide (100) to remove calcium deposits, wherein the removal device (200) includes a detachable bit (300).
[0012] The bit (300) may include a bit body (310) for removing lime deposits and a bit adapter for assembling the bit body (310) to a removal device (200).
[0013] The bit body (310) may include a bit body portion (312) that is formed in a cylindrical shape and extends long in the longitudinal direction, and a plurality of bit grooves (315) that are disposed at one end (313) of the bit body portion (312) and formed concavely from the outer surface toward the axis center (C).
[0014] A plurality of the bit grooves (315) are arranged spirally on the outer surface of the bit body part (312). The bit grooves (315) may be formed concavely.
[0015] One end (313) of the bit body part (312) is formed to be pointed, and in this embodiment, the one end (313) is formed in a conical shape, and the apex of the one end (313) can be positioned at the axis center (C) of the bit body part (312).
[0016] The above insertion guide (100) may include a bit guide part (110) that is inserted into the human body and has a guide hollow (115) formed therein so that the bit (300) can be inserted therein, a hopper part (120) that extends to the other side from the bit guide part (110), and a handle part (130) that extends downward from the hopper part (120).
[0017] First, since the bit protrudes into the human body through the insertion guide, the present invention has the advantage of minimizing damage to the human body caused by the movement of the bit and improving the recovery speed.
[0018] Second, since the present invention guides the bit to the bit guide section through the hopper section of the insertion guide, it has the advantage of preventing damage to the bit during the insertion process.
[0019] Third, the present invention has the advantage of improving surgical stability by fixing the insertion guide during surgery and minimizing damage to surrounding tissues.
[0020] Fourth, the present invention has the advantage of preventing bending deformation or frictional heat generated by high-speed rotation of the bit through a spiral inner groove formed on the inner circumference of the bit guide part.
[0021] Fifth, the present invention has the advantage of being able to rapidly dissipate heat from inside the insertion guide to the outside, as the inner groove can not only minimize the contact area with the bit but also allow fluid to flow in the longitudinal direction of the guide hollow.
[0022] Sixth, the present invention has the advantage of being able to more easily suck up and discharge crushed lime deposits through the inner groove.

In order to facilitate an overall understanding of the present invention, the same reference numerals are used for identical components in the drawings, and redundant descriptions of identical components are omitted.
[0037] FIG. 1 is an exploded front view of a non-surgical crushing suction removal device according to a first embodiment of the present invention, FIG. 2 is a front view of the bit shown in FIG. 1, and FIG. 3 is a front view of the insertion guide shown in FIG. 1.
[0038] The non-surgical crushing and suction removal device according to the present embodiment includes an insertion guide (100) that is inserted into the human body and provides a passage for surgery, and a removal device (200) that removes calcium deposits through the insertion guide (100).
[0039] The above removal device (200) includes a detachable bit (300).
[0040] The above removal device (200) includes a motor (not shown) that operates through applied power and a drive shaft (not shown) that rotates by the driving force of the motor, and the bit (300) is detachably assembled to the drive shaft.
[0041] The bit (300) includes a bit body (310) for removing lime deposits and a bit adapter for assembling the bit body (310) to a removal device (200).
[0042] One end of the bit body (310) is in contact with a lime deposit, and the other end is connected to the bit adapter.
[0043] The bit body (310) is formed in a cylindrical shape and includes a bit body portion (312) that extends long in the longitudinal direction, and a plurality of bit grooves (315) that are disposed at one end (313) of the bit body portion (312) and formed concavely from the outer surface toward the axis center (C).
[0044] The center of rotation of the bit body (310) is defined as the axis center (C).
[0045] In this embodiment, a plurality of bit grooves (315) are arranged spirally on the outer surface of the bit body portion (312). Since the bit grooves (315) are formed concavely, damage to human tissue can be minimized when removing the calcium deposits.
[0046] One end (313) of the bit body part (312) is formed to be pointed, and in this embodiment, the one end (313) is formed in a conical shape. The apex of the one end (313) is positioned at the axis center (C) of the bit body part (312).
[0047] In this embodiment, the outer diameter of the bit body part (312) is formed to be 1 mm.
[0048] The bit groove (315) may be formed only on one side of the bit body part (312).
[0049] The bit adapter is coupled to the other end (314) of the bit body part (312).
[0050] The bit adapter comprises an adapter body part (320) that is coupled to the other end (314) of the bit body part (312) and forms a diameter larger than the outer diameter of the bit body part (312), and an adapter catch part (330) that extends from the adapter body part (320) to the other side and forms a mutual catch with the drive shaft of the removal device (200).
[0051] The above adapter catch portion (330) includes teeth or catch grooves (332) arranged radially with respect to the axis center (C).
[0052] The above tooth profile or locking groove (332) is assembled with the drive shaft and transmits the rotational force of the removal device (200) to the bit body (310).
[0053] The adapter body part (320) includes a first adapter body part (321) formed to surround the other end of the bit body part (312) into which the other end of the bit body part (312) is inserted and coupled, a second adapter body part (322) that extends from the first adapter body part (321) to the other side and is formed with a larger diameter than the first adapter body part (321), and a third adapter body part (323) that extends from the second adapter body part (322) to the adapter catch part (330) side and is formed with a smaller outer diameter than the second adapter body part (322).
[0054] The outer diameter of the third adapter body part (323) is formed to be larger than that of the first adapter body part (321) and smaller than that of the second adapter body part (322).
[0055] Due to the difference in outer diameter between the second adapter body part (322) and the third adapter body part (323), a step is formed, and through the step, a more secure mutual locking can be formed with the removal device (200).
[0056] The insertion guide (100) has a guide hollow (115) formed therein so that a bit (300) can be inserted therein, and includes a bit guide part (110) inserted into the human body, a hopper part (120) extending to the other side from the bit guide part (110), and a handle part (130) extending downward from the hopper part (120).
[0057] The handle portion (130) extends downward from the bottom of the hopper portion (120).
[0058] The bit guide part (110) is formed in a cylindrical shape, and a guide hollow (115) is formed in the longitudinal direction inside.
[0059] One side of the guide hollow (115) is open and exposed to the inside of the human body, and the other side is connected to the inside of the hopper part (120).
[0060] The inner diameter of the guide hollow (115) is formed to be greater than 1 mm and less than or equal to 2 mm.
[0061] One end of the bit guide portion (110) is formed to be pointed. In this embodiment, the bit guide portion (110) forms a guide inclined surface (114) that is formed to be inclined downward toward the lower side.
[0062] The outer surface (112) of the bit guide part (110) is connected to the outer surface of the hopper part (120), and the inner surface (111) forms the guide hollow (115).
[0063] The bit (300) protrudes from one end of the guide hollow (115) and penetrates the guide inclined surface (114) to be exposed to the outside. That is, only one end (313) of the bit body part (312) is exposed to the outside from the guide inclined surface (114).
[0064] One end of the hopper section (120) is connected to the other end of the bit guide section (110).
[0065] The above hopper section (120) includes a hopper body section (122) that is formed pointed in one direction and has one end communicating with the guide hollow (115) of the bit guide section (110), and a hopper space (125) formed inside the hopper body section (122).
[0066] In this embodiment, the hopper body part (122) is formed in the shape of a truncated cone or a cone with a pointed side. Unlike this embodiment, the hopper body part (122) may be formed in the shape of a polygonal pyramid or a polygonal pyramid.
[0067] One side and the other side of the above hopper body part (122) are each opened.
[0068] The inner surface of the hopper body part (122) forms a hopper inclined surface (123).
[0069] With respect to the above axis center (C), the hopper inclined surface (123) is formed at an angle greater than 15 degrees and less than 30 degrees. Thus, the cone angle of the hopper space (125) is formed at an angle greater than 30 degrees and less than 60 degrees.
[0070] The above-mentioned axis center (C) is positioned to penetrate the guide hollow (115) and the hopper space (125). The above-mentioned axis center (C) is positioned to penetrate the center of a cross-section perpendicular to the longitudinal direction of the guide hollow (115) and to penetrate the center of a cross-section perpendicular to the longitudinal direction of the hopper space (125).
[0071] A cone-shaped hopper space (125) is formed inside the hopper section (120). One end of the hopper space (125) is formed to be pointed.
[0072] The inner diameter of the other end of the hopper space (125) is formed to be larger than the inner diameter of the first end.
[0073] The above hopper space (125) is formed such that the cross-section becomes narrower as it moves from one side to the other.
[0074] One end of the hopper space (125) is connected to the other end of the guide hollow (115).
[0075] Since the other side of the hopper space (125) is wide, the bit (300) can be easily inserted, and one end of the bit (300) can be easily guided to the guide hollow (115) through the hopper inclined surface (123).
[0076] The handle portion (130) extends downward from the bottom of the hopper portion (120). A plurality of grip protrusions (132) are formed along the length of the handle portion (130), thereby improving grip strength during use.
[0077]
[0078] FIG. 4 is a front cross-sectional view of an insertion guide and a bit according to a second embodiment of the present invention, and FIG. 5 is a cross-sectional view cut along AA of FIG. 4.
[0079] The insertion guide (100) according to the present embodiment further includes an inner groove (140) formed on the inner circumferential surface (111) of the bit guide portion (110) and formed in the longitudinal direction of the bit guide portion (110), and the inner groove (140) reduces resistance when the bit (300) rotates.
[0080] The crushed lime deposit can be sucked in through the insertion guide (100) and discharged to the outside. The inner groove (140) is characterized by providing a passage for the crushed lime deposit to move, thereby effectively enabling suction and discharge.
[0081] The inner groove (140) is formed concavely from the inner surface (111) toward the outer surface, one end is connected to the guide inclined surface (114), and the other end is connected to the hopper inclined surface (123).
[0082] In this embodiment, three inner grooves (140) are arranged.
[0083] The inner groove (140) includes a first inner groove (141), a second inner groove (142), and a third inner groove (143).
[0084] The first inner groove (141), the second inner groove (142), and the third inner groove (143) are arranged radially with respect to the above-mentioned axis center (C) and form an angle of 120 degrees between them.
[0085] The first inner groove (141), the second inner groove (142), and the third inner groove (143) may be formed in a straight line along the length direction of the bit guide part (110).
[0086] In this embodiment, the first inner groove (141), the second inner groove (142), and the third inner groove (143) are formed spirally along the longitudinal direction of the inner surface (111).
[0087] The first inner groove (141), the second inner groove (142), and the third inner groove (143) may be in the shape of a steel wire.
[0088] The spiral direction of the first inner groove (141), the second inner groove (142), and the third inner groove (143) is arranged in the rotational direction of the bit (300).
[0089] When viewed in a cross-section perpendicular to the longitudinal direction of the bit guide part (110), the first inner groove (141), the second inner groove (142), and the third inner groove (143) are formed in a semicircular shape.
[0090] The first inner groove (141), the second inner groove (142), and the third inner groove (143) can extend the guide hollow (115) radially outward, thereby reducing resistance generated during high-speed rotation of the bit (300).
[0091] Since the cross-sectional diameter of the bit (300) is formed to be 1 mm, it may bend or deform due to resistance during high-speed rotation or generate frictional heat.
[0092] The above inner groove has the feature of being able to reduce deformation or frictional heat that may occur during high-speed rotation of the bit (300), thereby ensuring operational reliability during surgery.
[0093] The first inner groove (141), the second inner groove (142), and the third inner groove (143) can not only minimize the contact area with the bit (300) but also allow fluid to flow in the longitudinal direction of the guide hollow (115), thus having the characteristic of being able to quickly discharge heat inside the insertion guide (100) to the outside.
[0094] In this embodiment, the inner groove (140) is formed to minimize the inner and outer diameters of the guide hollow (115), thereby minimizing the size of the perforation during surgery.
[0095] The remaining configurations below are similar to the first embodiment above, so a detailed description is omitted.
[0096]
[0097] FIG. 6 is a cross-sectional view of an insertion guide and a bit according to a third embodiment of the present invention.
[0098] Unlike the second embodiment, the non-surgical crushing suction removal device according to the present embodiment further includes a handle member (150) that is rotatably assembled to an insertion guide (100).
[0099] The above handle member (150) is installed instead of the handle part (130).
[0100] The above insertion guide (100) has a guide hollow (115) formed therein so that a bit (300) can be inserted therein, and includes a bit guide part (110) inserted into the human body, a hopper part (120) extending from the bit guide part (110) to the other side, and a handle installation part (160) extending from the hopper part (120) to the other side.
[0101] The handle installation part (160) is formed in a cylindrical shape and includes a handle installation body (162) extending to the other side from the hopper body part (122), a handle installation space (165) disposed inside the handle installation body (162) and communicating with the hopper space (125), and a handle guide (164) protruding radially outward from the handle installation body (162) and guiding the rotation of the handle member (150).
[0102] The handle installation body (162) is formed in a ring or cylindrical shape.
[0103] The handle guide (164) protrudes radially outward from the outer surface of the handle mounting body (162). The handle guide (164) is formed in a ring shape.
[0104] The inner surface (163) of the handle installation body (162) is connected to the hopper inclined surface (123).
[0105] The bit (300) can enter the hopper space (125) through the handle installation space (165).
[0106] The handle member (150) can be rotated along the handle guide (164).
[0107] The guide slope (114) must be positioned so as to face the lime deposit so that the lime deposit can be removed through the bit (300).
[0108] However, depending on the location of the lime deposit, it may be difficult to rotate the guide inclined surface (114), and as a result, when the handle part (130) is fixed to the insertion guide (100) as in the first embodiment, it may be difficult to fix the insertion guide (100).
[0109] In this embodiment, since the handle member (150) can be rotated relative to the insertion guide (100), there is an advantage in that the insertion guide (100) can be easily fixed or supported even if the lime deposit is in a difficult position.
[0110] The handle member (150) comprises a handle body (152) arranged to surround the handle mounting body (162), a guide groove (154) formed concavely outwardly from the inner circumference of the handle body (152) and into which the handle guide (164) is inserted, and a grip portion (156) extending outwardly from the handle body (152).
[0111] The above grip portion (156) may be in the shape of a bar, and a plurality of grip grooves (157) may be formed along the length direction on the outer surface.
[0112] The handle body (152) is formed in a ring shape or a cylindrical shape.
[0113] After the above handle body (152) is manufactured in two parts, left and right, it can be assembled to wrap around the above handle installation body (162).
[0114] The handle guide (164) is inserted into the guide groove (154).
[0115] The user can change the position of the grip portion (156) by rotating the handle member (150) while holding the insertion guide (100).
[0116] Although not separately explained, an inner groove (140) may be placed in the insertion guide (100) above.
[0117] The remaining configuration below is similar to the second embodiment, so a detailed description is omitted.
[0118]
