[0051]

[0052] The degradable balloons were prepared by the methods of Examples 1-30 respectively, and a complete integrated degradable balloon could be obtained without any holes, and the best uniformity was the formula of Example 1. .

[0053] In addition, using the preparation method of the degradable balloon in the above example, the degradable balloon is prepared. The degradable balloon can be used for various purposes according to the location of use, and can be used as a joint balloon and a cone balloon. Or the rotator cuff balloon is prepared into different shapes according to its shape requirements.

Abstract

The invention solves the problem that an existing method cannot well prepare a degradable balloon, and provides a preparation method of the degradable joint balloon and the degradable balloon preparedwith the method. The prepared balloon is of an integrated structure, does not hinder repairing of normal tissues while taking the supporting and buffering effects, and avoids the problems of degradation and decomposition of a degradable polymer in high-temperature processing. The preparation method comprises the following steps of S102, preparing an electrostatic spinning receiving device; S104,preparing a degradable polymer solution; S106, performing electrostatic spinning processing; S108, carrying out solvent treatment; and S110, performing demolding. The degradable balloon is characterized in that the preparation method of the degradable balloon according to any one of the claims is used.

Description

technical field [0001] The invention relates to the field of medical consumables, in particular to a method for preparing a degradable balloon and a balloon prepared by the method. Background technique [0002] Joint injuries such as ligament, joint capsule, tendon tear and other injuries are common injuries in daily life and sports in modern society. If it is not treated in time and effectively, it may cause sequelae such as obvious tendon contraction, low tissue quality, degeneration of articular cartilage, laxity of ligaments, repeated joint sprains, etc., seriously affecting the quality of daily life. [0003] At present, the clinical treatment methods for joint injuries include drug injection therapy, device-assisted therapy, arthroscopic debridement, partial repair, joint grafting or replacement, tendon transfer, prosthetic implantation and other methods. These methods are either expensive, or can only relieve symptoms but cannot fundamentally cure them, or cause majo...
