Description

Technical Field

[0001] The utility model relates to the field of liposuction and fat dissolving accessories, in particular to a blade protection sleeve for ultrasonic lipolysis. Background Art

[0002] At present, liposuction is the most important weight loss method in the field of plastic and cosmetic surgery, and is also an essential component of fat transplantation.

[0003] Ultrasonic liposuction is a very effective way to lose weight, and the weight loss effect is also very good. Ultrasonic liposuction has cohesive force in liquid or biological tissue, but the molecular adhesion of tissues with different densities is different. In low-density fat tissue, the molecular adhesion is weak, and the low negative pressure generated by ultrasound can produce tissue gaps, which is physically called "cavitation phenomenon". Then use a high-energy negative pressure aspirator to extract the liquefied fat liquid, which is a crusher of fat cells.

[0004] At present, ultrasonic lipolysis technology mostly uses ultrasonic lipolysis blades. Due to the inaccurate positioning of the ultrasonic lipolysis blade during the insertion of the protective tube, it will come into direct contact with the skin. Therefore, a blade protection cover is added to the ultrasonic lipolysis blade. The traditional blade protection cover has the disadvantages of being unable to rotate during the operation (it is easy to fall off when rotating) and the variable cross-section will cause the wound skin section to be uneven (such as Figure 7 In addition, attempts have been made to directly add a limiting structure to the side wall of the blade protection cover, but when the blade protection cover is removed, the added limiting structure is likely to cause secondary damage to the skin. Utility Model Content

[0005] The utility model aims to provide a blade protection cover for ultrasonic lipolysis, which can protect the skin during the ultrasonic lipolysis operation and can ensure that the blade protection cover is taken out when no damage is caused to the skin through deformation.

[0006] The utility model is realized by the following technical scheme: a cutting edge protection sleeve for ultrasonic lipolysis, which comprises a sleeve 11 and a cutting edge protection plate 12, wherein the proximal end of the sleeve 11 is connected to the cutting edge protection plate 12; and the cutting edge protection plate 12 is provided with a guide hole 121 communicating with the sleeve 11;

[0007] The feature is that: the outer circumference of the sleeve 11 is provided with two retaining structures for preventing the sleeve 11 from falling off;

[0008] The locking structure includes a buckle 112, a spring 111, a connecting rod 123 and a pressing plate 122;

[0009] The outer wall of the sleeve 11 is provided with a groove extending from the incision protection plate 12 to the distal end, and the groove does not extend to the distal end of the sleeve 11;

[0010] The spring piece 111 is arranged in the groove and the distal end of the spring piece 111 is connected to the distal end of the groove, and the buckle 112 is located outside the distal end of the spring piece 111; the inner end of the connecting rod 123 is connected to the proximal end of the spring piece 111, and the outer end of the connecting rod 123 extends out of the incision protection disk 12 and is connected to the pressing plate 122; the proximal end of the spring piece 111 is swung inward through the pressing plate 122, so that the spring piece 111 tilts inward, allowing the buckle 112 to be received in the groove.

[0011] Compared with the previous technology, the beneficial effects of the utility model are:

[0012] 1. It retains the characteristics of the traditional incision protection cover that protects the incision 360° all around. At the same time, when the surgical instrument is pulled out, the sleeve of the blade protection cover is equipped with a buckle for limiting and preventing it from falling off, which can minimize the friction between the blade protection cover and the skin, avoid skin damage, and ensure the stable and effective operation.

[0013] 2. The tension on the incision is uniform, which can effectively reduce tissue damage. The positioning structure can ensure that the liposuction tube or lipolysis knife can be adjusted at different angles and directions without falling off. This fixing method is simple, convenient, reliable and safe to operate. It can be suitable for incisions in different parts of the body and avoid wound pain, congestion, redness, swelling and pigmentation.

[0014] 3. When the incision protective cover is taken out, the buckle can shrink without damaging the skin incision section, and the incision recovers quickly. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The utility model is described in detail below in conjunction with the accompanying drawings, but the protection content of the utility model is not limited to the following:

[0024] like Figure 1-6 As shown, a cut edge protection sleeve for ultrasonic lipolysis comprises a sleeve 11 and a cut edge protection plate 12, wherein the proximal end of the sleeve 11 is connected to the cut edge protection plate 12; and the cut edge protection plate 12 is provided with a guide hole 121 communicating with the sleeve 11;

[0025] The feature is that: the outer circumference of the sleeve 11 is provided with two retaining structures for preventing the sleeve 11 from falling off;

[0026] The locking structure includes a buckle 112, a spring 111, a connecting rod 123 and a pressing plate 122;

[0027] The outer wall of the sleeve 11 is provided with a groove extending from the incision protection plate 12 to the distal end, and the groove does not extend to the distal end of the sleeve 11;

[0028] The spring piece 111 is arranged in the groove and the distal end of the spring piece 111 is connected to the distal end of the groove, and the buckle 112 is located outside the distal end of the spring piece 111; the inner end of the connecting rod 123 is connected to the proximal end of the spring piece 111, and the outer end of the connecting rod 123 extends out of the incision protection disk 12 and is connected to the pressing plate 122; the proximal end of the spring piece 111 is swung inward through the pressing plate 122, so that the spring piece 111 tilts inward, allowing the buckle 112 to be received in the groove.

[0029] When in use, the buckle 112 is put into the groove by pressing the pressing plate 122; after the blade protection sleeve is inserted into place, the pressing plate 122 is released, so that the popped-out buckle 112 is higher than the side surface of the sleeve 11, and the buckle 112 is stuck inside the skin tissue to prevent the blade protection sleeve from falling out. Of course, in actual use, the pressing plate 122 can be omitted, and the buckle 112 can be squeezed inward by the tissue to reduce damage to the tissue.

[0030] If it needs to be removed, the clip 112 can be put into the groove, and then the blade protection cover can be removed by pulling it up.

[0031] In actual design, the cut protection plate 12 is provided with a guide slot extending inwardly and outwardly, and the connecting rod 123 is placed in the guide slot. In this way, the connecting rod 123 can be guided and limited by the guide slot.

[0032] In the actual design process, the actual size of the cannula can be adjusted according to the actual situation. By designing a smaller cannula, the required incision length can be reduced, and it can be further applied to the action area of ​​the smaller ultrasonic lipolysis blade or the thinner subcutaneous tissue area (such as: around the eyes, face, neck, limbs, etc.). The positioning structure has the function of skin anchoring, and at the same time allows the channel inside the blade protection cover to rotate all around during the surgical operation, making the surgical operation more flexible and convenient.

[0033] The blade protection cover is fixed to the inner layer of the skin in a buckle manner so as not to shift or fall off during the suction process, and the fixing method can ensure that the protector can change with the angle change of the liposuction tube. The utility model can be sterilized by ethylene oxide and can also be used once.

[0034] Furthermore, the overall material of the utility model is PVC, PP, PTFE or silicone, so that it has the characteristics of anti-deformation, self-lubrication and biocompatibility, and can ensure that the material can be sterilized.

[0035] Generally speaking, the buckle 112 is in the shape of a chamfered edge, so as to ensure that the buckle 112 will not get stuck when the blade protection sleeve is inserted; and when not pressed, the buckle 112 can be opened at the bottom of the tissue.

[0036] The pressing plate 122 is an arc-shaped plate recessed toward the middle of the cut protection plate 12. The pressing plate 122 is two symmetrical finger-shaped structures, which play an auxiliary pinching and pressing role.

[0037] The utility model provides a blade protection cover for enlarging the skin incision and inserting and removing the blade, which cooperates with the skin protector for lipolysis or liposuction equipment to facilitate the insertion of the ultrasonic lipolysis blade into the skin. In addition, during the operation, the blade protection cover is kept in a specific position to block the direct contact between the liposuction tube or lipolysis knife and other surgical instruments and the skin at the incision, and the fixing method can ensure that the blade protection cover can change with the angle change of the liposuction tube. Since the buckle 112 may scratch the tissue, the buckle is contracted into the area inside the sleeve 11 by pressing the pressing plate 122 when it is removed. In this way, whether the blade protection cover is fixed or removed, it can be ensured that the buckle 112 will not cause damage to the tissue.

[0038] In addition, since the spring sheet 111 is not easy to press, a connecting rod 123 is added here to drive the entire spring sheet 111 and the buckle 112 to be received in the area below the surface of the sleeve 11, making it more convenient to use.

[0039] The pressing plate 122 is an arc-shaped concave structure that is recessed toward the cutout protection plate 12 .

[0040] The outer circumference of the sleeve 11 is provided with two retaining structures for preventing the sleeve 11 from falling off;

[0041] The two latching structures are arranged in mirror symmetry. The symmetrically arranged latching structures can achieve easier pressing, making the use of the utility model easier.

[0042] During use, the skin is first incised, and the blade protection cover is inserted into the skin incision. The ultrasonic lipolysis blade head is inserted into the subcutaneous fat layer through the skin protector to perform the operation. During the operation, water is continuously injected into the front end of the handle through the water injection channel and the front protective cover to cool down; the ultrasonic lipolysis blade head is inserted into the blade protection cover through the entrance formed by the guide hole, thereby avoiding direct contact between the lipolysis blade head and the skin at the incision site. The incision protection cover can prevent the ultrasonic lipolysis blade head from directly contacting the skin due to inaccurate positioning during the insertion of the protection tube.

[0043] After the operation is finished, the ultrasonic lipolysis blade is first pulled out, and then the buckle 112 is made not higher than the surface of the sleeve 11 by pressing the spring piece 111 or the pressing plate, and finally the blade protection cover is taken out.

[0044] In addition, after the pressing plate 122 is pressed into place, the outer contour size of the buckle structure is less than or equal to the outer diameter of the skin protection tube, which is convenient for insertion into the skin opening; buckles with different depths can be selected to adapt to different skin thicknesses. (The buckle depth can be 5 / 10 / 15 / 20 / 25mm, which basically covers the thickness of human abdominal skin).

[0045] In summary, the blade protection cover described in the utility model protects the skin of the incision area during ultrasound-assisted liposuction, so that the skin is not injured by heat and friction. The blade protection cover is made of a material that is resistant to deformation and can be sterilized by gas (ethylene oxide) or steam, so that it has an appropriate shape so that it can be kept in place during the operation. The introducer is used for blunt dissection to form a hole for inserting the blade protection cover and the ultrasound probe, and is also used as a guide when forming a skin incision of appropriate size. The operating member is used to expand the skin incision and to insert or remove the blade protection cover. The buckle has a skin anchoring function, which can minimize the possibility of the blade protection cover being accidentally pulled out of the incision.

[0046] like Figure 4 As shown: the skin is first incised, the blade protection cover is inserted into the skin incision, and the ultrasonic lipolysis blade is inserted into the blade protection cover and merged into the subcutaneous fat layer to perform the operation. The ultrasonic lipolysis blade is inserted into the entrance formed by the through hole in the blade protection cover, thereby avoiding direct contact between the lipolysis blade and the skin at the incision site. The incision protection plate can prevent the ultrasonic lipolysis blade from directly contacting the skin due to inaccurate positioning during the insertion of the protection tube.

[0047] Although the utility model uses specific embodiments and their alternatives to illustrate and describe the utility model, it should be understood that various changes and modifications can be implemented as long as they do not deviate from the spirit and scope of the utility model. Therefore, it should be understood that except for the limitations of the attached claims and their equivalents, the utility model is not limited in any sense.
