Example Embodiment

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or a centered element may also exist. When an element is considered to be "connected" to another element, it can be directly connected to the other element or an intermediate element may be present at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

Abstract

The invention provides a mold for preparing a degradable joint balloon and a use method thereof. During using, a degradable polymer solution is prepared first; the prepared degradable polymer solutionis injected into a forming cavity of a combined mold through any runner; after the degradable polymer solution is solidified, a first external mold and a second external mold are detached to obtain afirst mold release product; dissolving a soluble internal mold in the first mold release product to obtain a second mold release product; changing clean water to clean the second mold release productfor multiple times; and after the second mold release product is dried, a degradable balloon can be prepared, wherein the degradable balloon is prepared by using a degradable polymer material with good biocompatibility, can be gradually degraded in vivo and absorbed by human body within 2-18 months, can have a supporting and stress buffering effect, cannot obstruct the repairing of normal tissuesand does not need to be taken out through second operation.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a mold for preparing a degradable joint balloon and a use method thereof. 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...
