Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The invention provides a material implanter for cartilage grafting minimally invasive surgery, which comprises an outer sleeve 3, an inner sleeve 2 and a compression bar 1, wherein the inner sleeve 2 is arranged in the outer sleeve 3, and the compression bar 1 is arranged in the inner sleeve 2 as shown in figures 1, 2, 3, 4 and 5; the lower end of the inner sleeve 2 is provided with a limit groove 22, the lower end of the compression bar 1 is provided with a compression block 12, and the compression block 12 is arranged in the limit groove 22; in use, after the outer sleeve 3 is inserted into the surgical incision and positioned in the cartilage defect area, the compression block 12 is driven by applying a force to the compression rod 1 in the longitudinal direction to implant and adhere the cartilage graft material more tightly.
Further, the diameter of the compression block 12 is larger than the inner diameter of the inner sleeve 2.
Further, a boss 11 for limiting the downward sliding of the compression bar 1 is arranged at the upper end of the compression bar 1, and the boss 11 is matched with the upper end face of the inner sleeve 2.
Further, a protruding part 21 for limiting the inner sleeve 2 from sliding down is arranged at the upper end of the inner sleeve 2 around the circumference of the cylinder wall, and the protruding part 21 is matched with the upper end face of the outer sleeve 3.
Further, the distance from the lower end face of the outer sleeve 3 to the lower end face of the inner sleeve 2 is 1-3 mm; by setting this distance of 1 to 3mm, it is avoided that even if the compression block 12 is pressed downward by a mishandling force, the cell-rich cartilage graft (MACI) material is not destroyed.
Further, as shown in fig. 6, an insert 4 is arranged between the boss 11 and the upper end face of the inner sleeve 2; the inserting piece 4 is in a double-ended open spanner shape, one end of the inserting piece 4 is a hard inserting piece 41, and the other end is an elastic inserting piece 42; preferably, the hard insert 41 is made of stainless steel; the elastic tab 42 is made of rubber; when the hard insert 41 is inserted between the boss 11 and the inner sleeve 2, the compression block 12 is positioned in the limit groove 22 and clings to cartilage graft (MACI) material; when the elastic insert 42 is inserted, the compression bar 1 is pressed, and the compression bar 1 drives the compression block 12 to implant cartilage graft (MACI) material by means of the elastic force of the elastic insert 42 and make the cartilage graft (MACI) material more tightly adhered to fibrin glue.
Further, as shown in fig. 1, a viewing groove 32 is provided on the lower end side wall of the outer sleeve 3; by providing the observation groove 32 on the sidewall of the outer sleeve 3, the operator can observe the descending depth of the implanted cartilage graft (MACI) material.
Further, as shown in fig. 1 and 4, the lower end of the outer sleeve 3 is provided with a taper, and by providing the taper at the lower end of the outer sleeve 3, an operator can conveniently and rapidly insert the outer sleeve 3 into an operation incision, so that pain of a patient is reduced; the upper end of the outer sleeve 3 is provided with a handle 31, and the handle 31 is arranged, so that an operator can conveniently take the outer sleeve 3.
