1. A circular knitting machine jacquard needle equipped with a return structure installed in a circular knitting machine which includes a plurality of knitting needles controlled by a plurality of cams and a plurality of computer needle selected device which includes a plurality of needle selected sheets and a plurality of jacquard needles located on an upper needle dial; the jacquard needles are driven by the cams in normal conditions to move the knitting needles, the needle selected sheets being movable downwards to depress the jacquard needles to escape from the cams, each of the jacquard needles comprising:
a fulcrum connected with the knitting needle;
a neck extended from the fulcrum;
a force received section which is connected to the neck and includes a plurality of needle butts depressed by the needle selected sheets;
a needle foot which is extended from the force received section and located in a slide track formed on the cam in normal conditions; and
a return structure which is extended from the neck and includes a bend end at a distal end beneath the needle foot to butt an inner wall of the upper needle dial, and spaced from the force received section by a retraction gap to form a movement space while the force received section is depressed by the needle selected sheet, the return structure being bendable upon receiving a depressing force through the neck to generate an elastic force to rebound the force received section back.
2. The circular knitting machine jacquard needle equipped with a return structure of claim 1, wherein the return structure is formed in an arched manner and extended from the neck to the bend end.
3. The circular knitting machine jacquard needle equipped with a return structure of claim 1, wherein the neck is connected to the force received section through a shoulder which is extended upwards from the neck such that the force received section is at a higher horizontal elevation than the neck in the circular knitting machine.
4. The circular knitting machine jacquard needle equipped with a return structure of claim 3, wherein the shoulder includes an arched notch at one end of the retraction gap to reduce stress.
5. The circular knitting machine jacquard needle equipped with a return structure of claim 1, wherein the return structure is selectively an elastic plate, an elastic rod or an elastic strut.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An orthopedic implant for implantation into a cavity formed within an anatomical structure, comprising:
a bag including a fill access providing access to an interior of said bag; and
a structural support disposed at least partially within said bag.
2. The orthopedic implant of claim 1, wherein said structural support comprises a tube having an exterior wall and an interior wall defining a hollow interior.
3. The orthopedic implant of claim 2, wherein said bag is fixedly secured to at least one end of said tube.
4. The orthopedic implant of claim 2, further comprising a retaining ring circumferentially capturing said bag against said tube.
5. The orthopedic implant of claim 2, wherein said tube includes insertion tool engagement structure.
6. The orthopedic implant of claim 1, further comprising a lag, said lag cooperating with said structural support.
7. The orthopedic implant of claim 6, wherein said lag comprises at least one radially expandable finger.
8. The orthopedic implant of claim 7, wherein said lag comprises a plurality of radially expandable fingers.
9. The orthopedic implant of claim 8, wherein said lag has a central axis and upon axial compression of said lag along said central axis, said radially expandable fingers are deformable to radially expand.
10. The orthopedic implant of claim 1, wherein said bag comprises at least one material selected from the group consisting of biocompatible acrylic material, polymer material, glass fiber material, ceramic fiber material, stainless steel fiber material, titanium fiber material, titanium alloy fiber material, tantalum fiber material, shape-memory material, and hydrogel materials.
11. An orthopedic implant assembly for implanting an orthopedic implant into a cavity formed within an anatomical structure, comprising:
an orthopedic implant, said orthopedic implant comprising:
a bag including a fill access providing access to an interior of said bag; and
a structural support disposed at least partially within said bag, said structural support including first engagement structure; and
an implant insertion tool including second engagement structure engageable with said first engagement structure, said implant insertion tool including at least one passage which is placed in fluid communication with said fill access of said bag upon engagement of said first engagement structure with said second engagement structure.
12. The orthopedic implant assembly of claim 11, wherein said structural support comprises a tube having an exterior wall and an interior wall defining a hollow interior.
13. The orthopedic implant assembly of claim 12, wherein said bag is fixedly secured to at least one end of said tube.
14. The orthopedic implant assembly of claim 12, further comprising a retaining ring circumferentially capturing said bag against said tube.
