An elastic tightening band for vaginal tightening

Abstract

The present invention relates to an elastic tightening band for vaginal tightening, which includes a tightening band and a traction line arranged on the tightening band. The tightening band is made of an implant-grade elastic material into a long strip shape. The tightening band includes at least one force decomposition area along the longitudinal direction, and at least one through-seam is arranged on the force decomposition area. The through-seam evenly divides the force decomposition area along the longitudinal direction. A number of fixing holes are symmetrically arranged on both side edges of the tightening band. The inelastic traction line passes through the fixing holes in a crossed manner in sequence. The tightening band is arranged at different thickness layers at intervals along the transverse or oblique direction. The structure of the present invention is simple. The arrangement of the through-seam can change the force application direction on the tightening band and decompose the contraction force of the tightening band. The different thickness layers arranged at intervals along the transverse or oblique direction can make the force expansion degree of the tightening band different. Therefore, as an auxiliary instrument for vaginal tightening treatment, the tightening band can adapt to the different activities of multiple levels of the vaginal surrounding muscles, and further affect the vaginal folds to achieve a better postoperative effect.

Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to an elastic tightening band for vaginal tightening. Background Art

[0002] Vaginal relaxation refers to the relaxation, tearing, and aging of the vaginal sphincter, levator ani muscle, perineal muscles, ligaments, and elastic fiber structures in women due to natural childbirth or other reasons, resulting in thinning and relaxation of the vaginal wall. Vaginal relaxation can cause some pelvic floor dysfunction diseases such as stress urinary incontinence and uterine prolapse. The functional levels of the muscle groups around the vagina are complex, and the tendon fascia and elastic fiber tissues are crisscrossed. Traditional surgical treatments cannot compensate for the muscle strength of the vaginal sphincter and the elasticity of the surrounding tissues. Existing biological bands do not have the function of decomposing contraction force and have a uniform thickness. Therefore, when in use, they cannot adapt to the different activities of the multi-level surrounding muscle groups, have poor fusion with autologous tissues, and are prone to cause local discomfort after surgery. Summary of the Invention

[0003] The present invention provides an elastic tightening band for vaginal tightening, which solves the problems of mechanical defects and poor fusion with autologous tissues existing in existing biological bands in clinical use.

[0004] The present invention adopts the following technical solutions:

[0005] An elastic tightening band for vaginal tightening, comprising a tightening band and traction lines arranged on the tightening band. The tightening band is made of an implantable elastic material into a long strip shape. At least one force decomposition area is arranged longitudinally on the tightening band. At least one through-seam is arranged on the force decomposition area, and the through-seam evenly divides the force decomposition area longitudinally. A plurality of fixing holes are symmetrically arranged on both side edges of the tightening band. The traction lines pass through the fixing holes on both side edges in a crossed manner. Different thickness layers are arranged at intervals along the transverse or oblique direction of the tightening band.

[0006] Further, the width of the tightening band is 0.1 - 1.0 cm.

[0007] Further, the thickness of the tightening band is 0.1 - 3.0 mm.

[0008] Further, one end of the tightening band is arranged in a pointed shape to reduce the resistance when the tightening band enters the tissue.

[0009] Clinically, the contraction force generated by the tightening band is the reaction force of the expansion force. In the structure of ordinary biological bands, there is no setting of through-slits for force decomposition. Therefore, the contraction force of the ordinary band is directly borne by the tissue under the surface it binds and cannot be decomposed. The tightening band of the present invention is provided with a through-slit structure. During use, the contraction force of the tightening band is evenly decomposed. When the reaction force (resultant force) is the same, the more component forces there are, the more delicate and gentle the effect on the bound tissue will be. During the tissue expansion process of the present invention, due to the setting of the through-slits, the surface of the tightening band will be split open, forming gaps for adjusting the uneven thickness of local tissue occupancy. By changing the direction of the tightening force, the influence of the tightening effect of the tightening band on adjacent tissues is reduced, enabling the tightening force to have a gentle fluctuation space according to the expansion requirements, and thus being more adaptable to the different activities of the multi-level muscle groups around the vagina.

[0010] The advantages of the present invention are as follows:

[0011] (1) The structure of the present invention is simple and compact. The implant-grade elastic material can be selected according to the clinical use requirements to have different flexibility and mechanical properties. At least one force decomposition area is set on the tightening band, and at least one through-slit is set in each force decomposition area. The setting of the through-slits will change the force direction on the tightening band during use to decompose the contraction force. The different thickness layers arranged horizontally or obliquely at intervals can make the tightening band expand differently under force, thereby affecting the dynamics of the vaginal folds.

[0012] (2) The inelastic traction lines cross-set on the tightening band of the present invention can ensure that the elasticity of the tightening band is fixed in blocks, enabling the tightening band to pass through the tissue more smoothly, avoiding implantation failure and causing more damage to the vaginal wall.

[0013] (3) The present invention can assist in achieving vaginal tightening during surgery, achieving a comfortable and normal effect, and having a good degree of fusion with vaginal tissues. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the above-mentioned objects, features, and advantages of the present invention more obvious and understandable, the following further describes the specific embodiments of the present invention with reference to specific drawings.

[0020] The implant-grade elastic material described in the present invention is made of implant-grade silicone rubber material, implant-grade polyurethane material, etc.

[0021] Embodiment 1

[0022] As Figure 1 shown, an elastic tightening band 1 for vaginal tightening, the tightening band 1 is made of implant-grade silicone rubber material, the tightening band 1 is in a long strip shape, the length of the tightening band 1 is 15 cm, the width is 1 cm, and the thickness is 3.0 mm. There is only one force decomposition area 5 on the tightening band 1, and two through-slits 4 are provided in the force decomposition area 5.

[0023] Two through-slits 4 are arranged longitudinally and parallelly on the tightening band 1 to decompose the contraction force of the tightening band 1, enabling the tissues in the acting area of the tightening band 1 to obtain fine-tuning conditions under the restraint of different contraction forces. The two through-slits 4 divide the tightening band evenly into a first edge area, a middle area, and a second edge area. The tightening band forms areas with different thicknesses in the transverse direction, where thick layers and thin layers are arranged alternately. As Figure 1 shown, the thickened parts at the edges of the tightening band are thickened areas. It can be seen that the thickened areas on the tightening band are arranged at intervals. The setting of this structure enables different degrees of deformation to occur when the tightening band is expanded. The thin parts deform more than the thick parts, thus affecting the dynamics of the vaginal folds.

[0024] A plurality of fixing holes 3 are provided in the first edge area, and fixing holes 3 identical to those in the first edge area are symmetrically arranged on the second edge area. The traction line 2 starts from the fixing hole 3 at the end of the tightening band and passes through the fixing holes 3 in the first edge area and the second edge area in a crossed manner in turn. The traction line 2 is used to connect the threading needle at the head end of the tightening band. The non-elastic traction line 2 passes through a plurality of fixing holes 3 in the first edge area and the second edge area in turn, enabling the tightening band to be stressed in sections when implanted into tissues, and it can enter the tissues while maintaining a small elastic deformation. One end of the tightening band 1 is set to be pointed to reduce the resistance when the tightening band enters the tissues.

[0025] Embodiment 2

[0026] As Figure 2 shown, an elastic tightening band 1 for vaginal tightening, the tightening band 1 is made of implant-grade polyurethane material, the tightening band 1 is in a long strip shape, the length of the tightening band 1 is 15 cm, the width is 0.8 cm, and the thickness is 3.0 mm. There are only two force decomposition areas on the tightening band, and each force decomposition area is provided with a through-slit. The tightening band forms areas with different thicknesses in the transverse direction. Figure 2The thickened part at the edge of the tightening band is the thickened area. It can be seen that the thickened areas on the tightening band are arranged at intervals.

[0027] Fixed holes 3 are symmetrically arranged on both sides of the tightening band 1. The inelastic traction line 2 passes through the fixed holes 3 in a crossed manner in the same way as in Embodiment 1, and a threading needle is connected to one end of the tightening band 1.

[0028] Embodiment 3

[0029] As Figure 3 shown, a stretch tightening band for vaginal tightening is made of medical silicone rubber material. The tightening band is in a long strip shape, with a length of 15 cm, a width of 0.5 cm, and a thickness of 0.1 mm. Only one force decomposition area is provided on the tightening band, and only one through-seam is provided on the force decomposition area. The tightening band forms areas with different thicknesses in the transverse direction. The thickened part at the edge of the tightening band in the figure is the thickened area. It can be seen that the thickened areas on the tightening band are arranged at intervals.

[0030] Fixed holes 3 are symmetrically arranged on both sides of the tightening band 1. The inelastic traction line 2 passes through the fixed holes 3 in a crossed manner in the same way as in Embodiment 1, and a threading needle is connected to one end of the tightening band 1.

[0031] Embodiment 4

[0032] As Figure 4 shown, a stretch tightening band for vaginal tightening is made of medical silicone rubber material. The tightening band is in a long strip shape, with a length of 15 cm, a width of 0.1 - 1 cm, and a thickness of 2.0 mm. Only two force decomposition areas are provided on the tightening band, and only three through-seams are provided on each force decomposition area. The tightening band forms areas with different thicknesses along the diagonal direction. The thickened part at the edge of the tightening band in the figure is the thickened area. It can be seen that the thickened areas on the tightening band are arranged at intervals.

[0033] Fixed holes 3 are symmetrically arranged on both sides of the tightening band 1. The inelastic traction line 2 passes through the fixed holes 3 in a crossed manner in the same way as in Embodiment 1, and a threading needle is connected to one end of the tightening band 1.

[0034] Processing method:

[0035] (1) Select an implantable elastic material with appropriate flexibility and mechanical properties according to clinical needs, and perform a film-making treatment on the elastic material to obtain a tightening band material with alternating thicknesses.

[0036] (2) Use a stamping die that integrates tape cutting, slitting (slitting according to the requirements of different numbers of force decomposition areas and different through-seams), and punching to stamp a tightening band of a certain length. Sufficient positions for fixed sutures should be left at both ends of the head and tail of the tightening band.

[0037] (3) Pull line fixing method: Take a non-elastic pull line, fold it in half according to the required length, and start from the fixed hole at the end of the tightening band. Use the positive "Z" shape threading method of "through the left hole → through the right hole → through the left hole → through the upper right hole → through the upper left hole..." at one end and the reverse "Z" shape threading method of "through the right hole → through the left hole → through the right hole → through the upper left hole → through the upper right hole..." at the other end. Pass the line through the fixed hole at the beginning of the tightening band in an alternating manner. The two ends of the pull line are interlaced in the hole and then passed out to form a pull line head for connecting the traction needle;

[0038] (4) Package and sterilize for future use.

[0039] Directions:

[0040] (1) The band can be cut to a suitable length according to the needs of the operation. The needle is inserted through the skin between the labia minora and the vaginal opening (such as the 3 o'clock position), and the needle is passed through the posterior vaginal wall in a semicircle to the opposite side (such as the 9 o'clock position). After the band is implanted in place, the traction line at the end of the band is cut and the traction line is pulled out.

[0041] (2) Tighten the ends of the band until the required tightening is achieved, cut off the excess part of the band, and suture the band to the deep tissue to fix it;

[0042] (3) Steps (1) and (2) may be repeated as needed, but the locations where the tightening band passes may be different to increase the length of the tightened vagina.
