Embodiment 1

[0032] Special-shaped balloons that reduce human soft tissue and other tissue damage, such as Figure 1~2 As shown, its preparation method is: first extrude PLA with biocompatibility from the extruder to form a special-shaped balloon blank, which is composed of three sub-balloon blanks with openings. Two adjacent sub-balloon blanks are connected by a lamination line, and then each sub-balloon blank is formed by gas injection and blow molding using a balloon molding machine; wherein, the wall thickness of the sub-balloon is 0.1mm;

[0033]Each sub-balloon is columnar after inflated, all sub-balloons are arranged side by side, and the two ends of all sub-balloons and all pressing lines are flush; and along the arrangement direction of the sub-balloons, each sub-balloon The arc tapers toward its two ends, the distance between two adjacent sub-balloons is 0.4cm, and the distance between two adjacent pressing lines is 1cm; along the extension direction of each sub-balloon, the dist...

Embodiment 2

[0039] Special-shaped balloons that reduce human soft tissue and other tissue damage, such as Figure 3-4 As shown, the preparation method is as follows: first extrude biocompatible PLGA from the extruder to form a special-shaped balloon blank, which is composed of four sub-balloon blanks with openings. The two adjacent sub-balloon blanks are connected by a lamination line, and then the balloon molding machine is used to perform gas injection and blow molding on each sub-balloon blank; wherein, the wall thickness of the sub-balloon is 0.3mm;

[0040] Each sub-balloon is columnar after being inflated, all the sub-balloons are arranged side by side, and the two ends of all the sub-balloons and all the pressing lines are flush; and along the arrangement direction of the sub-balloons, the outermost sub-balloon The a-end is far away from the middle sub-balloon, the b-end is close to the middle sub-balloon, the outermost sub-balloon tapers from the middle to its a-end in a straight ...

Embodiment 3

[0043] Special-shaped balloons that reduce human soft tissue and other tissue damage, such as Figure 5-6 As shown, its preparation method is: first extrude the PCL with biocompatibility from the extruder to form a special-shaped balloon blank, which is composed of two sub-balloon blanks with openings. The two adjacent sub-balloon blanks are connected by a lamination line, and then the balloon molding machine is used to perform gas injection and blow molding on each sub-balloon blank; wherein, the wall thickness of the sub-balloon is 0.3mm;

[0044] One sub-balloon is spherical after inflation, and the other sub-balloon is hollow ring after inflation. The spherical sub-balloon is located in the hollow part of the hollow ring-shaped sub-balloon. The width of the pressing line is 0.2cm, and the hollow ring The width of the shaped sub-balloon is 0.4cm, the height of each sub-balloon is 0.8cm, and the height of the lamination line is 0.2mm;

[0045] The special-shaped balloon for...

Abstract

The invention relates to a special-shaped balloon for reducing human soft tissue and other tissue damage and a preparation method thereof. Firstly, a biocompatible material is extruded from an extruder to form a special-shaped balloon blank, and the special-shaped balloon blank is mainly It is composed of a plurality of sub-balloon blanks with openings, two adjacent sub-balloon blanks are connected by a lamination line, and then the balloon molding machine is used to perform gas injection and blow molding on each sub-balloon blank; the prepared The special-shaped balloon is an inflatable and biocompatible balloon, which is mainly composed of multiple sub-balloons, and two adjacent sub-balloons are connected by a pressing line. The special-shaped balloon for alleviating human soft tissue and other tissue damage of the present invention has a simple preparation method; the surface of the special-shaped balloon is uneven, the stability at the transplantation site is better, it is not easy to slip, and it can be stressed at multiple points during the movement, so The average force to a single point is small, and the pressure is relatively small, which can play a better buffering role and improve the wear fastness.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a special-shaped balloon for alleviating human soft tissue and other tissue damage and a preparation method thereof. Background technique [0002] After repeated strenuous movements, delicate soft tissues are often damaged by wear and tear by rubbing against each other and / or hard tissues such as bone. Torn tendons of the rotator cuff and ruptured joint capsules are examples of such injuries. Additionally, inflammation, infection, disease, and / or genetic predispositions to degeneration of these tissues can adversely affect these tissues. [0003] In order to solve the above problems, the patent CN104473704A discloses a prosthesis (balloon) for reducing human soft tissue and other tissue damage. For expansion, the filler can be gas, liquid or gel. This kind of gap filling can indirectly improve the smooth movement of joint tissues and relieve pain caused by joint discomfor...
