Embodiment 1

[0026] Such as figure 1 As shown, the anti-snoring implant disclosed in this embodiment includes a body made of degradable material through injection molding process. Degradable materials include polyglycolide, polylactide, polycaprolactone, or polydioxanone, or copolymers or blends of the above materials. A preferred embodiment is: the degradable material adopts poly(glycolide-caprolactone) copolymer and polydioxanone. In this embodiment, the main body is processed by injection molding process using poly(glycolide-caprolactone) copolymer, and the degradation period is 6 months.

[0027] When defining the use of the instrument, the end away from the operator is the distal end, and the end close to the operator is the proximal segment. In this embodiment, from the distal end to the proximal end, the body has the distal anchoring pawl 1 , the distal connecting rod 2 , the middle contraction section 3 , the proximal connecting rod 4 and the proximal anchoring ring 5 .

Embodiment 2

[0032] Such as image 3 As shown, the difference between the anti-snoring implant disclosed in this embodiment and Embodiment 1 is:

[0033] 1) The body is made of poly(glycolide-L-lactide) copolymer through injection molding process, and the degradation cycle is 5 months.

[0034] 2) The middle shrinkage section 3 is a continuous V-shaped structure in which multiple V-shaped ends are connected end to end.

[0035] 3) When the body is in a natural state, the length of the body is 16 mm, and the length of the middle contraction section 3 is 5 mm. The maximum outer diameter of the body is 2.6mm. After loading into the delivery system, the body is stretched to 26 mm with a maximum outer diameter of 2.0 mm.

[0036] Other structures and working principles of this embodiment are the same as those of Embodiment 1.

Embodiment 3

[0038] Such as Figure 4 As shown, the difference between the anti-snoring implant disclosed in this embodiment and Embodiment 1 is:

[0039] 1) The main body is woven from polydioxanone silk, and the degradation cycle is 6 months.

[0040] 2) The middle shrinkage section 3 is a spiral structure.

[0041] 3) When the body is in a natural state, the length of the body is 15 mm, and the length of the middle contraction section 3 is 5.5 mm. The maximum outer diameter of the body is 2.1mm. After loading into the delivery system, the body is stretched to 27mm and has a maximum outer diameter of 1.85mm.

[0042] 4) The anti-snoring implant is implanted into the body by a needle delivery device. Before implantation, the distal end of the implant is secured on a needle and the proximal end is stretched by a thread. When reaching the lesion site, the implant is released in the body, and during the recovery process of the middle contraction section 3, the tissue and the barbs are c...

Abstract

The invention relates to a snore-ceasing implant which is characterized by comprising a body made of a degradable material; the body is in a natural state without external force, the body can be stretched and lengthened under the external force so as to be changed into a stretched state from the natural state, and after the external force is removed, the body in the stretched state automatically retracts to the natural state; during the implanting process of the snore-ceasing implant, the body is in a stretched state; after the snore-ceasing implant is implanted, the body in the stretched state automatically retracts to the natural state until the length is kept stable; the outer surface of the body is provided with barbs, and tissues can be driven to contract through the barbs in the automatic retraction process of the body in the stretched state. The implant is stretched to be lengthened before being implanted and can automatically retract after being implanted, so that the length is reduced, and in the process of retracting the implant to the original length, the barbs at the two ends tightly grab tissues to shorten the length of the soft palate, so that the cross sectional area of an oropharynx ventilation cavity is increased, and the risk of sleep apnea is relieved or eliminated.

Description

technical field [0001] The invention relates to a stent implant, which is used to prevent snoring and reduce the risk of sleep apnea, and belongs to the technical field of medical devices. Background technique [0002] Obstructive sleep apnea is a sleep-breathing disease with sleep snoring accompanied by apnea and daytime drowsiness as the main clinical manifestations. It generally refers to the cessation of mouth and nose airflow for 10 seconds in the medical definition every time an attack occurs. Or longer, accompanied by a drop in blood oxygen saturation. During the 7 hours of sleep for adults every night, the number of attacks often reaches more than 30 times. The disease can cause intermittent hypoxia, hypercapnia, and sleep disorder, and can lead to hypertension, coronary heart disease, arrhythmia, cerebrovascular disease, cognitive dysfunction, type II diabetes and other multi-organ and multi-system damage. The etiology and risk factors include: age, sex, obesity, ...
