Description
Technical field
This utility model relates to medicine technology field, particularly a kind of degradable composite tubular urethra rack.
Background technology
Traumatic or iatrogenic urethral injury, the urethral stricture that the gonococcal or various factors such as nonspecific urethritis and congenital urethra pathological changes causes is one of difficult problem of facing of urological surgeon.Conventional treatments comprises urethral dilatation, internal urethrotomy, end-to-end anastomosis of urethra etc. and is only applicable to the shorter urethral stricture patient of distance, patient for long section urethral stricture mainly adopts alternative operative treatment, and genital skin, bladder mucosa, albuginea penis, oral mucosa and lingual mucous membrane are all used as the patching material of urethra prosthesis; But draw materials and usually can cause the complication at position of drawing materials, and the amount of drawing materials is restricted.
Summary of the invention
The purpose of this utility model causes for when existing and draw materials in existing long section urethral stricture Therapeutic Method the weak point that wound, material taken amount are limited, position of drawing materials easily leads to complications, and provides a kind of degradable composite tubular urethra rack.
This utility model completes in the following way: a kind of degradable composite tubular urethra rack, this degradable composite tubular urethra rack is a kind of degradable tissue engineering bracket, comprise internal layer and skin, internal layer is tubulose, and skin is located on the outer surface of internal layer; Described internal layer and skin all adopt degradable macromolecular material and acellular matrix to make.
In the degradable composite tubular urethra rack of described one, described makes internal layer and outer field degradable high polymer material employing Poly(D,L-lactide-co-glycolide PLGA thin film, and described acellular matrix adopts small intestinal acellular matrix SIS thin film; Interconnect between Poly(D,L-lactide-co-glycolide PLGA thin film and small intestinal acellular matrix SIS thin film.
In the degradable composite tubular urethra rack of described one, pass through between described Poly(D,L-lactide-co-glycolide PLGA thin film with small intestinal acellular matrix SIS thin film together with suturing with thread management; Described Poly(D,L-lactide-co-glycolide PLGA thin film and small intestinal acellular matrix SIS thin film are all in strip structure; Described line is employing 9/0 nylon wire.
In the degradable composite tubular urethra rack of described one, described skin is wrapped on the outer surface of internal layer by spiral way.
In the degradable composite tubular urethra rack of described one, Poly(D,L-lactide-co-glycolide PLGA thin film on described internal layer and the placing flat of small intestinal acellular matrix SIS film water, longitudinal separation arrangement is stitched together in the form of sheets, around catheter external latasuture synthesis tubulose.
In the degradable composite tubular urethra rack of described one, the Poly(D,L-lactide-co-glycolide PLGA thin film on described skin and small intestinal acellular matrix SIS thin film level are intervally arranged and are stitched together in strip.
In the degradable composite tubular urethra rack of described one, described internal layer is arranged by the Poly(D,L-lactide-co-glycolide PLGA thin film of two rectangles and the small intestinal acellular matrix SIS thin film longitudinal separation of two rectangles and is formed; Described skin is intervally arranged by two rectangular-shaped Poly(D,L-lactide-co-glycolide PLGA thin film and two rectangular-shaped small intestinal acellular matrix SIS thin film levels and is stitched together.
This utility model has good biocompatibility and mechanical property, has both elasticity and pliability, can keep stable tube-like condition in vivo; What this utility model adopted is polymeric biomaterial and acellular matrix, is conducive to seed cell and sticks, breeds and break up, and promotes the growth of surrounding tissue; Bi-material can progressively be decomposed into small-molecule substance by respective mode and naturally absorb in vivo, without the need to taking out.
Adopting this utility model to carry out urethra Reparation and Reconstruction, without the need to carrying out autologous drawing materials, avoiding the complication that position of drawing materials may cause; Mucous membrane of urethra epithelial cell, stem cell, smooth muscle cell etc. can adhere to and breed on support, can be directly used in urethra Reparation and Reconstruction, are applicable to clinical practice.
