Problems solved by technology

[0002] At present, the clinical treatment of anal fistula is mainly based on surgery, including anal fistula incision, anal fistula thread setting, sphincter preservation surgery, etc., gradually changing from open surgery with large trauma to minimally invasive surgery, from incision surgery to surgery. Restorative surgery, however, for the treatment of complex anal fistula, postoperative recurrence, slow healing and other clinical problems, there is no good solution and equipment. Most of the existing tissue closures use materials that cannot be absorbed by the human body. When the internal opening of anal fistula is closed, stainless steel nails are used to anastomose the incision, or titanium alloy closing clips are used to close the internal opening of anal fistula. The steel nails or closing clips need to be removed by secondary surgery, which increases the pain of the patient and the risk of surgery, and causes harm to the patient. greater psychological trauma

Embodiment 1

[0032] Embodiment one, with reference to Figure 1 to Figure 14: A degradable anal fistula internal opening occluder, comprising a coil-shaped implant main body 1, the coil-shaped implant main body 1 also includes irregular tooth-shaped protrusions, and the irregular tooth-shaped protrusions are connected with the coil-shaped implants respectively. The implant body 1 is connected and fixed. The coil-shaped implant body 1 is composed of two right-hand helical structures. Both ends of the coil-shaped implant body 1 are quadrilateral cross-sections 101. The irregular tooth-shaped protrusions include the outer protrusions 2 and The downward convex 3 and the external convex 2 include triangular arc protrusions, which protrude clockwise along the coil-shaped implant body 1, and the downward protrusions 3 are pointed downward protrusions. The connection part of the coil-shaped implant body 1 and the triangular arc protrusion of the outer protrusion 2 contains a fillet 4, and the conn...

Embodiment 2

[0033] Embodiment two, refer to Figure 1 to Figure 10 : The main body 1 of the coil-shaped implant is set to 3, 4 and 5 sections, the best number of helical structures through the coil-shaped implant is 2 sections, and 3, 4 and 5 sections are produced according to the actual situation, which is convenient according to the patient's situation to use.

Embodiment 3

[0034] Embodiment three, refer to Figure 1 to Figure 10 : The coil-shaped implant body 1 includes two sections of right-hand helical structure, the total length of the coil-shaped implant body 1 is 10mm, the pitch of the coil-shaped implant body 1 is 5mm, and the largest outer diameter of the coil-shaped implant body 1 protrudes The diameter is 8.2mm, the width of the triangular arc protrusion along the coil-shaped implant body 1 is 0.51 mm, the height of the triangular arc protrusion is 1.2 mm, and the height of the tine protrusion is 0.71 mm. The included tooth angle is 30-60°, the total length of the coil-shaped implant body 1 remains unchanged at 10 mm, and the pitches of the three-segment coil-shaped implant body 1 are 3.3 mm, 2.5 mm, and 2 mm, respectively.

[0035] When in use, an absorbable coil-shaped implant body 1 is wrapped around the inner opening of the anal fistula through the push assembly 5, and provides circumferential compression of the inner opening of the...

Abstract

The invention discloses a degradable anal fistula internal opening plugging device, which comprises a coil-shaped implant main body, the coil-shaped implant main body further comprises irregular tooth-shaped protrusions, the irregular tooth-shaped protrusions are connected and fixed to the coil-shaped implant main body, the coil-shaped implant main body is composed of two sections of right spiral structures, the two ends of the coil-shaped implant body are both quadrilateral sections, the irregular tooth-shaped protrusions comprise outer protrusions and lower protrusions, and the outer protrusions comprise triangular arc protrusions. The degradable anal fistula internal opening plugging device is used for closing an inner opening of anal fistula, curing a fistulous tract, preventing relapse and keeping a normal defecation function, the plugging device material has good biocompatibility, can ensure that inflammatory reaction does not occur after the plugging device is implanted into a human body, can be completely degraded within six months, does not need secondary operation, and achieves the treatment effect of no foreign matter in the body; the plugging device is an absorbable coil-shaped implant with irregular tooth-shaped protrusions, is simple in structure and convenient to operate, and can be rapidly implanted into the body of a patient to reduce pain.
