这是什么

Remplir 神经包裹套是一种由天然猪组织制成的保护性套管。它用于神经手术中,以帮助修复受损神经。该装置旨在解决修复部位形成瘢痕组织的问题。瘢痕组织可能会阻碍神经信号传导并延缓愈合过程。

包裹套在缝合后的神经周围形成生物屏障。它可减少修复部位内部胶原纤维的堆积。这有助于保持该区域通畅,促进神经恢复。我们使用此包裹套在愈合过程中支持您的神经。它为神经再生提供了一个稳定的环境,避免过度瘢痕形成。

产品成分

该包裹由经动物组织处理的生物材料制成。其设计用于包裹神经,以引导神经愈合。您的外科医生会在手术过程中将其放置于神经周围,以支持修复部位。

该材料并非永久性植入物。随着神经愈合,它会在体内逐渐分解并溶解。该过程通过去除细胞以确保安全性,仅保留支持性结构,从而促进自然组织重塑。

外科医生如何使用该产品

外科医生可能在原发性外膜神经修复术中使用猪源性细胞外基质神经包裹物。这是对神经外层进行的直接修复。包裹物被放置在神经吻合口周围,即神经断端连接处。它有助于减少该区域的胶原沉积。然而,与单独进行原发性外膜神经修复相比,它并不能改善轴突再生、神经肌肉接头再支配或功能恢复。

我们还在复发性肘管综合征的二次减压术中使用该包裹物。当症状复发时,这是一种安全有效的治疗方法。在某些情况下,外科医生可能会使用纯化 I 型牛胶原导管来修复前臂远端的正中神经。这些导管充当管道,用于桥接长达 3 厘米的指部感觉神经缺损。它们有助于恢复感觉,并避免需要进行神经自体移植(即从您身体的其他部位取组织)。对于小于 3 厘米的缺损, processed nerve allografts(处理过的神经同种异体移植物)是另一种选择,与神经导管相比,在 6 个月时显示出更早改善的预后结果。

预期情况

您的外科医生会使用由天然组织制成的包裹物覆盖修复后的神经。该材料有助于减少修复部位的瘢痕组织增生。与单独进行标准修复相比,它并不能加速神经再生或改善肌肉功能。您的康复过程与主要手术相同。请参阅该手术页面的具体时间表和康复步骤。

该包裹物会随着时间逐渐在体内溶解。您无需担心它会在未来的X光或MRI检查中显现。它在常规影像学扫描中不可见。如果您对瘢痕组织或神经感觉有任何疑问,我们可以在随访期间进行讨论。我们的团队将指导您完成针对您具体手术的标准康复过程。

证据表明

研究表明,在初级神经修复中使用猪细胞外基质神经包裹物并不能改善轴突再生、神经肌肉接头再支配或功能恢复,与单纯修复相比无优势。然而,它可以减少修复部位内的胶原沉积。在复发性肘管综合征联合进行二次减压时,该材料也是一种有效且安全的选项。

对于3厘米或更短的指神经缺损,胶原神经管提供了一种恢复感觉的临床有效方法。它避免了神经自体移植相关的供区问题。在12个月的随访中,神经导管和 processed nerve allografts(处理过的神经同种异体移植物)对于这些缺损的感觉重建效果相当。然而,与神经导管相比,处理过的神经同种异体移植物在6个月时显示出更早的改善结果。

对于较大、较长、混合性或运动性神经缺损,神经自体移植仍然是金标准。在动物模型中,对于10毫米的神经缺损,自体移植在运动神经恢复方面优于胶原神经导管。可生物降解的神经导管在神经松解术后也能提供针对周围神经粘连的保护作用。对于某些应用,证据仍在积累中,需要更长期的研究来全面了解所有结果。

Our licenses are irrevocable. Licensors should read and understand the terms and conditions of the license they choose before applying it. Licensors should also secure all rights necessary before applying our licenses so that the public can reuse the material as expected. Licensors should clearly mark any material not subject to the license. This includes other CC- licensed material, or material used under an exception or limitation to copyright.

Considerations for the public: By using one of our public licenses, a licensor grants the public permission to use the licensed material under specified terms and conditions. If the licensor's permission is not necessary for any reason--for example, because of any applicable exception or limitation to copyright--then that use is not regulated by the license. Our licenses grant only permissions under copyright and certain other rights that a licensor has authority to grant. Use of the licensed material may still be restricted for other reasons, including because others have copyright or other rights in the material. A licensor may make special requests, such as asking that all changes be marked or described. Although not required by our licenses, you are encouraged to respect those requests where reasonable.

1. automatically as of the date the violation is cured, provided it is cured within 30 days of Your discovery of the violation; or

2. upon express reinstatement by the Licensor.

For the avoidance of doubt, this Section 6(b) does not affect any right the Licensor may have to seek remedies for Your violations of this Public License.

c. For the avoidance of doubt, the Licensor may also offer the Licensed Material under separate terms or conditions or stop distributing the Licensed Material at any time; however, doing so will not terminate this Public License.
