Description

Calcification device for soft tissue calcification lesions

The present invention relates to a descaling device for soft tissue calcified lesions, and more particularly, to a descaling device for soft tissue calcified lesions capable of effectively removing lime for calcific tendonitis disease occurring in the shoulder joint.

Soft tissue calcification is the deposition of calcium in soft tissue, and a typical example is calcific tendonitis.

Calcific tendinitis of the shoulder joint is a disease that causes acute and chronic pain around the shoulder due to the deposition of calcium in the rotator cuff.

Conservative treatment typically includes administration of non-steroidal anti-inflammatory drugs and subacromial steroid injection therapy, but temporary pain relief can be expected, but the treatment effect is limited because it cannot fundamentally remove the deposited lime.

Non-surgical methods to remove deposited lime include multiple perforation, lavage aspiration, and extracorporeal shock wave therapy.

Multiple puncture and irrigation aspiration have been evaluated as useful methods to relieve acute pain by reducing increased intra-tendon pressure and promote drainage and resorption of calcified nodules.

However, since this method has difficulty in accurately determining the site of lime deposition, a method using fluoroscopy or ultrasound has been attempted to accurately insert the injection needle.

After confirming the location and form of lime deposits through ultrasound examination and disinfecting the treatment area, local anesthesia is performed on the skin, subcutaneous tissue, and subacromial bursa using 5 ml of 1% lidocaine at the location where the injection needle will be inserted.

After anesthesia, multiple puncture is performed on the calcined area with a 20-gauge injection needle, and then an injection solution of 1% 1ml lidocaine and 1ml steroid (Triamcinolone acetonide, 40 mg/ml) is mixed into the subacromial bursa while avoiding the perforated area. inject

Extracorporeal shock wave therapy is emerging in terms of high therapeutic effect and non-invasive method, and shock wave therapy is performed after marking the location of lime using ultrasound.

In Korean Patent Publication No. 10-2014-0074884 and Publication Patent Publication No. 10-2019-0079155, techniques for treatment using shock waves are shown.

10 is a perspective view of a hollow discharge member according to a fourth embodiment of the present invention, and FIG. 11 is a use process diagram of the hollow discharge member according to a fourth embodiment of the present invention.

Compared to the above-described first embodiment, the fourth embodiment has a difference in that it further includes a hollow discharge member 70 as shown in FIG. 10, and this will be mainly described.

In the first embodiment, small pieces of crushed lime 50 were discharged to the outside using the crushing member 20 having a hollow shape.

However, when the pieces of crushed lime 50 are large, it is difficult to discharge them to the outside through the inside of the crushing member 20.

In this case, the hollow discharge member 70 according to this embodiment is mounted.

The hollow discharge member 70 is made of a hollow shape.

In addition, a suction member 40 made of a vacuum pump or the like is mounted on the other end of the hollow discharge member 70 .

As shown in FIG. 11 (a), after crushing the lime 50 with the crushing member 20 and the guide member 10 and removing the crushing member 20 and the guide member 10, FIG. 11 ( As shown in b), the hollow discharge member 70 is inserted and disposed adjacent to the pieces of crushed lime 50.

At this time, the inner diameter of the hollow discharge member 70 is formed larger than the inner diameter of the crushing member 20.

After that, when the suction member 40 is operated, since the diameter of the hollow discharge member 70 is larger than the diameter of the crushing member 20, as shown in FIG. 11(c), the crushed lime 50 Even if the size of the pieces is large, the pieces of lime 50 crushed by the crushing member 20 by the operation of the suction member 40 pass through the inside of the hollow discharge member 70 to the suction member 40. is moved to and discharged.

In addition, one end of the hollow discharge member 70 for sucking the pieces of lime 50 into the inside may be formed open along the longitudinal direction in an inclined shape like a general syringe needle, but as shown in the drawings of the present embodiment, It is preferable that the opened end of the hollow discharge member 70 is bent in the lateral direction of the longitudinal direction of the hollow discharge member 70 .

As the open end of the hollow discharge member 70 is formed as described above, it is possible to prevent one end of the hollow discharge member 70 from being blocked by pieces of lime 50 .

The present invention, a descaling device for soft tissue calcification lesions, is not limited to the above-described embodiment, and may be modified and implemented in various ways within the scope permitted by the technical concept of the present invention.

The present invention can be used as a device for removing lime according to soft tissue calcified lesions, and thus has industrial applicability.
