Description

Technical Field

[0001] This invention relates to an improved non-surgical abrasive removal device that minimizes tissue damage to remove scale from calcified tendinitis. Background Technology

[0002] Calcific tendinitis of the rotator cuff is a relatively common shoulder joint condition. Although the exact cause is unclear, it was first described by Duplay in 1872 as "glenohumeral nerve root". It was called "frozen shoulder", but in 1934, Codman reported that the condition did not occur in the subacromial bursa, but rather within the rotator cuff.

[0003] Calcific tendinitis refers to a condition in which calcification occurs within the rotator cuff through a reactive calcification process, causing inflammation and extreme pain. The exact cause of rotator cuff calcification is unclear, but its specific relationship with trauma is also unknown. It is known to be associated with systemic diseases such as diabetes, thyroid disorders, and estrogen metabolism, and some theories suggest a link to these conditions. There is some genetic predisposition.

[0004] In some cases, calcified tendinitis can be relieved with the use of nonsteroidal anti-inflammatory drugs (NSAIDs), physical therapy, and steroid injections into the subacromial space, and the limestone may be absorbed naturally. However, if the limestone is not removed, the symptoms may disappear. Frequent recurrences or persistent pain are also possible.

[0005] Limestone can be broken up using lithotripsy or removed via arthroscopy or open surgery.

[0006] Surgical removal of limestone from the rotator cuff can significantly reduce pain the following day and usually does not recur, making it a good treatment option. However, it involves the burden of general anesthesia and pain in the surgical area. Post-operatively, the high cost of surgery often places a physical, psychological, and financial burden on patients.

[0007] To overcome these drawbacks of surgical treatment, a method for removing limestone using ultrasound-guided lithotripsy under local anesthesia has been developed. However, the outcome of such lithotripsy often depends on the operator's skill.

[0008] If the surgery is performed well, the lime will be absorbed slowly within a month after the lithotripsy. However, if the surgery is not performed well, lime often remains, which usually leads to surgical treatment.

[0009] The deposition removal device can remove large amounts of lime with high probability by overcoming the shortcomings of traditional lime lithotripsy treatment that only uses simple needles, while minimizing damage to the tendons.

[0015] The problem that the invention aims to solve

[0016] The present invention addresses the aforementioned problems and aims to provide a non-surgical pulverizing and aspirating removal device that can pulverize and aspirate lime while minimizing tissue damage.

[0017] means for solving problems

[0018] The present invention includes an insertion guide 100 inserted into the human body and providing a channel; a removal device 200 introduced into the human body through the insertion guide 100 to remove lime deposits; it includes a non-surgical grinding and suction removal device comprising a removable drill bit 300.

[0019] The drill bit 300 has a drill bit body 310 for removing lime deposits, and the drill bit body 310 is assembled into a removal device 200, which may include a drill bit adapter.

[0020] The drill bit body 310 is cylindrical and has a longitudinally extended drill bit body portion 312 disposed at one end 313 of the drill bit body portion 312, and has an axis C on its outer peripheral surface. It may include a plurality of concave drill bit grooves 315.

[0021] Multiple drill bit grooves 315 are arranged in a spiral pattern on the outer peripheral surface of the drill bit body 312. The drill bit grooves 315 can be formed in a concave shape.

[0022] One end 313 of the drill bit body 312 is sharp; in this embodiment, the end 313 is conical, and the apex of the end 313 is the apex of the drill bit body 312. Axis center C.

[0023] The insertion guide 100 has a guide hollow portion 115 formed therein to allow the drill bit 300 to be inserted, and includes a drill bit guide portion 110 inserted into the human body. The insertion guide 100 may include an extended funnel portion 120 on the other side, and a handle portion 130 extending downward from the funnel portion 120.

[0024] Invention Effects

[0025] First, the present invention has the following advantages: it minimizes the harm to the human body caused by the movement of the drill bit, and improves the recovery speed because the drill bit protrudes into the human body after passing through the insertion guide.

[0026] Secondly, since the present invention guides the drill bit to the drill bit guide portion through the hopper portion of the insertion guide, it has the advantage of preventing damage to the drill bit during the drill bit insertion process.

[0027] Third, the present invention has the advantage of improving surgical stability and minimizing damage to surrounding tissues by fixing the insertion guide during surgery.

[0028] Fourth, the present invention has the advantage of preventing bending deformation or frictional heat caused by the high-speed rotation of the drill bit through the helical inner groove formed on the inner circumferential surface of the drill bit guide portion.

[0029] Fifth, in this invention, because the inner groove not only minimizes the contact area with the drill bit but also allows fluid to flow longitudinally along the hollow portion of the guide, heat inserted into the guide can be quickly dissipated to the outside. This is an advantage. Attached Figure Description

[0047] Figure 1 This is an exploded front view of the non-surgical grinding suction removal device according to the first embodiment of the present invention. Figure 2 yes Figure 1 The front view of the drill bit shown. Figure 3 This is the main view of the insert. (Guidelines follow...) Figure 1 As shown.

[0048] The non-surgical abrasive removal device according to this embodiment includes an insertion guide 100 inserted into the human body to provide a surgical channel and a removal device 200 for removing lime deposits through the insertion guide 100.

[0049] The removal device 200 includes a removable drill bit 300.

[0050] The removal device 200 includes a motor (not shown) that is operated by applying power and a drive shaft (not shown) that is rotated by the driving force of the motor, and the drill bit 300 is connected to the drive shaft and is detachably assembled.

[0051] The drill bit 300 has a drill bit body 310 for removing lime deposits, and the drill bit body 310 is assembled into a removal device 200 including a drill bit adapter.

[0052] One end of the drill body 310 is in contact with lime deposits, while the other end is connected to the drill adapter.

[0053] The drill bit body 310 is cylindrical and has a longitudinally extended drill bit body portion 312 located at one end 313 of the drill bit body portion 312, and has an axis C on its outer peripheral surface. It includes a plurality of concave drill bit grooves 315.

[0054] The rotation center of the drill body 310 is defined as the axis C.

[0055] In this embodiment, multiple drill grooves 315 are arranged in a spiral pattern on the outer peripheral surface of the drill body 312. Since the drill grooves 315 are concave, damage to human tissue can be minimized when removing lime deposits.

[0056] One end 313 of the drill bit body 312 is sharp; in this embodiment, one end 313 is conical. The apex of one end 313 is located at the axis C of the drill bit body 312.

[0057] In this embodiment, the outer diameter of the drill bit body 312 is 1 mm.

[0058] The drill bit groove 315 may be formed only on one end of the drill bit body portion 312.

[0059] The drill bit adapter is connected to the other end 314 of the drill bit body part 312.

[0060] The drill bit adapter is connected to the other end 314 of the drill bit body portion 312 and has an adapter body portion 320, the diameter of which is larger than the outer diameter of the drill bit body portion 312, and the adapter body portion 320 extends from the other end. It also includes an adapter locking portion 330 that is interlocked with the drive shaft of the removal device 200.

[0061] The adapter locking portion 330 includes teeth or locking grooves 332 arranged radially relative to the axis center C.

[0062] The tooth or locking groove 332 is assembled with the drive shaft and transmits the rotational force of the removal device 200 to the drill body 310.

[0063] The adapter body portion 320 is connected by insertion into the other end of the drill bit body portion 312, and includes a first adapter body portion 321 formed around the other end of the drill bit body portion 312, and first adapter body portions 321, 322 extending from the body portion 321 to the other side, and formed to have a larger diameter than the first adapter body portions 321 and 322. Figure 2 As shown, it includes a third adapter body portion 323, which extends from the adapter body portion 322 toward the adapter locking portion 330 and has an outer diameter smaller than that of the second adapter body portion 322.

[0064] The outer diameter of the third adapter body 323 is greater than the outer diameter of the first adapter body 321 and less than the outer diameter of the second adapter body 322.

[0065] The difference in outer diameter between the second adapter body 322 and the third adapter body 323 forms a step, which can form a more secure interlock with the removal device 200.

[0066] The insertion guide 100 has a guide hollow portion 115 formed therein to allow the drill bit 300 to be inserted, a drill bit guide portion 110 inserted into the human body, and an extended funnel portion of the drill bit guide portion 110 located on the other side. It also includes a hopper portion 120 and a handle portion 130 extending downward from the hopper portion 120.

[0067] The handle unit 130 extends downward from the bottom of the hopper unit 120.

[0068] The drill bit guide portion 110 is formed in a cylindrical shape, and a guide recess 115 that is longer in the length direction is formed inside it.

[0069] One side of the guide hollow 115 opens and exposes the inside of the human body, while the other side is connected to the inside of the hopper unit 120.

[0070] The inner diameter of the guide cavity 115 is greater than 1 mm and less than 2 mm.

[0071] One end of the drill bit guide portion 110 is formed as a sharp point. In this embodiment, the drill bit guide portion 110 forms a downwardly inclined guide slope 114.

[0072] The outer peripheral surface of the hopper section 120 is connected, and the inner peripheral surface 111 forms a guide recess 115.

[0073] The drill bit 300 protrudes from one end of the guide hollow 115, passes through the guide slope 114, and is exposed to the outside. That is, only one end 313 of the drill bit body 312 is exposed to the outside on the guide slope 114.

[0074] One end of the hopper unit 120 is connected to the other end of the drill bit guide unit 110.

[0075] The hopper section 120 is formed into a sharp point in one direction and has a hopper body section 122 and a hopper body section 122. One end of the hopper body section 122 communicates with the guide hollow section 115 of the drill bit guide section 110. The hopper section 120 includes a hopper space 125 formed inside it.

[0076] In this embodiment, the hopper body 122 is formed as a truncated cone or a cone with a cusp on one side. In contrast, the hopper body 122 may be formed as a polygonal pyramid or a pyramidal shape.

[0077] One side and the other side of the main body of the hopper 122 are open.

[0078] The inner surface of the hopper body 122 forms the hopper inclined surface 123.

[0079] The inclined surface 123 of the hopper is formed at an angle greater than 15 degrees and less than 30 degrees relative to the axis C. Therefore, the cone angle of the hopper space 125 is formed at an angle greater than 30 degrees and less than 60 degrees.

[0080] The axis C is configured to pass through the guide cavity 115 and the hopper space 125. The axis C is configured to pass through the center of a cross section orthogonal to the longitudinal direction of the guide cavity 115 and through the center of a cross section orthogonal to the longitudinal direction of the hopper space 125.

[0081] The hopper section 120 has a conical interior forming a hopper space 125. One end of the hopper space 125 is sharp.

[0082] The inner diameter of the other end of the hopper space 125 is larger than the inner diameter of the first end.

[0083] The hopper space 125 is formed to have a narrower cross-section as it moves from one side to the other.

[0084] One end of the hopper space 125 is connected to the other side of the guide cavity 115.

[0085] The other side of the hopper space 125 is wider, so the drill bit 300 can be easily inserted, and one end of the drill bit 300 can be easily guided through the hopper inclined surface 123 to the guide cavity 115. It has usable features.

[0086] The handle unit 130 extends downward from the bottom of the hopper unit 120. A plurality of grip protrusions 132 are formed along the longitudinal direction of the handle portion 130, which can improve the grip strength during use.

[0087] A front sectional view of the insertion guide and drill bit according to a second embodiment of the present invention. Figure 5 It is along Figure 4 A sectional view taken from AA.

[0088] According to this embodiment, the insertion guide 100 is formed on the inner peripheral surface 111 of the screwdriver bit guide portion 110, and also includes an inner groove 140 formed along the longitudinal direction of the screwdriver bit guide portion 110. The inner groove 140 reduces the resistance during insertion. The drill bit 300 rotates.

[0089] The inner groove 140 is formed concavely from the inner peripheral surface 111 to the outer peripheral surface, with one end connected to the guide inclined surface 114 and the other end connected to the hopper inclined surface 123.

[0090] In this embodiment, there are three inner grooves 140.

[0091] The inner groove 140 includes a first inner groove 141, a second inner groove 142 and a third inner groove 143.

[0092] The first inner groove 141, the second inner groove 142, and the third inner groove 143 are arranged radially based on the axis center C and form an angle of 120 degrees with each other.

[0093] The first inner groove 141, the second inner groove 142, and the third inner groove 143 can be formed as a straight line along the longitudinal direction of the drill bit guide portion 110.

[0094] In this embodiment, the first inner groove 141, the second inner groove 142 and the third inner groove 143 are formed in a spiral shape along the length direction of the inner circumferential surface 111.

[0095] The first inner groove 141, the second inner groove 142 and the third inner groove 143 may have a wire-like shape.

[0096] The first inner groove 141, the second inner groove 142 and the third inner groove 143 are arranged in the spiral direction of the drill bit 300.

[0097] When viewed from a cross section perpendicular to the longitudinal direction of the screwdriver tip guide portion 110, the first inner groove 141, the second inner groove 142, and the third inner groove 143 are formed in a semi-circular shape.

[0098] The first inner groove 141, the second inner groove 142, and the third inner groove 143 can expand the guide cavity 115 radially outward, thereby enabling the drill bit 300 to rotate at high speed. This reduces the resistance generated during rotation.

[0099] The cross-sectional diameter of the drill bit 300 is 1 mm, so it may deform or generate frictional heat due to resistance during high-speed rotation.

[0100] The inner groove can reduce the deformation or frictional heat that may be generated when the drill bit rotates at high speed of 300, which has the characteristic of ensuring the reliability of operation during surgery.

[0101] The first inner groove 141, the second inner groove 142, and the third inner groove 143 not only minimize the contact area with the drill bit 300, but also extend longitudinally along the guide cavity 115. Because fluid can flow, heat-injected material inside the guide 100 can be quickly expelled to the outside.

[0102] Thus, in this embodiment, the inner and outer diameters of the guide cavity 115 can be minimized by forming the inner groove 140, and thereby the size of the perforation during surgery can be minimized.

[0103] In the following text, since the remaining configurations are similar to those in the first embodiment, detailed descriptions will be omitted.

[0104] A front sectional view of the insertion guide and drill bit according to a third embodiment of the present invention.

[0105] Unlike the second embodiment, the non-surgical abrasion and suction removal device according to this embodiment also includes a handle member 150 that is rotatably assembled relative to the insertion guide 100.

[0106] The handle component 150 is installed to replace the handle part 130.

[0107] The insertion guide 100 has a guide hollow portion 115 formed therein to allow the drill bit 300 to be inserted, a drill bit guide portion 110 inserted into the human body, and an extended funnel portion of the drill bit guide portion 110 located on the other side. It also includes a hopper portion 120 and a handle mounting portion 160 extending from the hopper portion 120 to the other side.

[0108] The handle mounting portion 160 is cylindrical and includes a handle mounting body 162 extending from the hopper body portion 122 to the other side, and is disposed inside the handle mounting body 162 and in the handle of the hopper space A. It also includes a mounting space 165 communicating with 125, and a radially outwardly projecting handle mounting body 162, which includes a handle guide 164 that guides the rotation of the handle member 150.

[0109] The handle mounting body 162 is formed in a ring or cylindrical shape.

[0110] The handle guide 164 protrudes radially outward from the outer peripheral surface of the handle mount 162. The handle guide 164 is formed in a ring shape.

[0111] The inner circumferential surface 163 of the handle mounting body 162 is connected to the inclined surface 123 of the hopper.

[0112] The drill bit 300 can enter the hopper space 125 through the handle mounting space 165.

[0113] The handle component 150 can rotate along the handle guide 164.

[0114] The guide ramp 114 must be set to face the lime deposit so that the lime deposit can be removed by the drill bit 300.

[0115] However, depending on the location of the lime deposit, the inclined surface 114 of the guide may be difficult to rotate, so when the handle portion 130 is fixed to the insertion guide 100 as in the first embodiment, the insertion guide 100 may be difficult to fix.

[0116] In this embodiment, since the handle member 150 can rotate relative to the insertion guide 100, it has the advantage of being able to easily fix or support the insertion guide 100 even when the lime deposit is in a difficult position.

[0117] The handle component 150 includes a handle body 152 configured to surround the handle mount 162 and formed to be radially recessed from the inner peripheral surface of the handle body 152, and a handle guide 164 including a guide groove 154, into which the handle guide 164 is inserted, and a grip portion 156 extending radially outward from the handle body 152.

[0118] The grip portion 156 may have a strip shape, and a plurality of grip grooves 157 may be formed on the outer surface along the longitudinal direction.

[0119] The handle body 152 is formed in the shape of a ring or a cylinder.

[0120] After the handle body 152 is made into left and right parts, it can be assembled into a body 162 that surrounds the handle.

[0121] The handle guide 164 is inserted into the guide slot 154.

[0122] The position of the grip 156 is changed by rotating the handle member 150 while holding the insertion guide 100.

[0123] Although not explained separately, the internal recess 140 may be provided in the insertion guide 100.

[0124] Hereinafter, since other structures are the same as in the second embodiment, detailed descriptions will be omitted.

[0125] Specific embodiments have been described in the detailed description of this invention; however, various modifications can, of course, be made without departing from the scope of the invention. Therefore, the scope of the invention should not be limited to the described embodiments, but should be determined not only by the scope of the patent claims described subsequently, but also by the scope of the claims of this patent and their equivalents.
