23 Jul MINIMALLY INVASIVE SURGICAL INSTRUMENT FOR CARTILAGE TRANSPLANT WITH TISSUE ENGINEERING
Abstract
A minimally invasive surgical instrument for cartilage transplant with tissue engineering comprises a forceps (1) having two forceps tips (2) as curved tips. The forceps tip (21) disposed on an upper side is provided with through holes (5) distributed uniformly on a surface of the forceps tip (21), wherein the through holes (5) pass through two side surfaces of an upper side and a lower side of the forceps tip (21), and a first barrier portion (8) is provided between two adjacent through holes (5); the forceps tip (22) disposed on a lower side is provided with recesses (6) on an outer surrounding wall, and the recesses (6) are disposed at an interval along the outer surrounding wall, and have locations corresponding to the locations of the through holes (5), wherein a second barrier portion (7) is provided between two adjacent recesses (6), and a rectangular tooth-shaped structure is formed between the recess (6) and the second barrier portion (7). The holder having two curved forceps tips (2) provided with holes and teeth respectively forms suture holes after closed, thus addressing the problem of holding a collagen membrane in place during arthroscopic suturing.
