Patent Application
20190076139
A button is used in a rotator cuff surgical procedure to retain a tendon to a bone. A hole is drilled in the bone. A suture anchor is then inserted into the hole in the bone, and a suture strand attached to the suture anchor is used to secure the tendon to the bone. The button is located above the tendon, and the suture strand is tied to assist in securing the tendon to the bone.
The button can be made of stainless steel, titanium alloy, titanium, PEEK, PLLA or any material. As the button is solid, the tissue cannot incorporate into the button, allowing the button to shift over time.
A surgical repair assembly includes a button including a body portion formed of embroidered yarn. The button includes at least one aperture. A suture strand engages the button to secure soft tissue to the bone, and the suture strand is received in the at least one aperture of the button.
In one example, the suture anchor can be received in a hole in a bone, and the suture strand can engage the suture anchor. In one example, the body portion includes two apertures to receive the suture strand. Each of the two apertures can be oblong in shape. The tissue button can include a suture eyelet loop secured to the body portion of the tissue bottom. The suture eyelet loop can be integral with the body portion of the tissue button to define a single integral monolithic unitary component. The suture eyelet loop can also be secured to the body portion by glue or a knot. The yarn of the suture anchor can be polyester yarn.
A surgical repair assembly includes a suture anchor received in a hole in a bone. A tissue button includes a body portion formed of polyester embroidered yarn and a feature through which a suture strand is threaded. The suture strand engages the suture anchor and the tissue button to secure soft tissue to the bone. Soft tissue is secured between the tissue button and the bone.
In one example, the feature is two apertures, and the body portion includes the two apertures to receive the suture strand. Each of the two apertures can be oblong in shape. The feature can be a suture eyelet loop, and the tissue button includes the suture eyelet loop which is secured to the body portion of the tissue bottom. The suture eyelet loop is integral with the body portion of the tissue button to define a single integral monolithic unitary component. The feature can be a slit, and the tissue button includes the slit.
A method of performing a surgical repair includes inserting a suture anchor into a hole in a bone, passing the suture strand through soft tissue, passing the suture strand through a slit in a fixation button, pulling the suture strand through a knot pusher, pushing the fixation button towards the soft tissue, temporarily fixing the soft tissue against the bone with the fixation button, and securing the suture strand to secure the soft tissue to the bone after the step of temporarily fixing.
Other advantages of the present invention can be understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:
When repairing a rotator cuff tear, a hole 12 is drilled in the bone 14. A suture anchor 16 is then inserted in the hole 12 in the bone 14. A suture strand 18 is secured by the suture anchor 16 to the bone 14. In one example, the suture strand 18 is located around a rigid member in the suture anchor 16. In another example, the suture strand 18 is wedged between the suture anchor 16 and the bone 14.
The suture strand 18 is threaded through the tendon 20 (or other tissue, such as a ligament). An embroidered tissue button 22 is positioned above the tendon 20 and is employed to secure the tendon 20 to the bone 14 to repair the tear. The suture strand 18 passes through defined apertures 24 in the embroidered tissue button 22, and the suture strands 28 are tied in a knot 26 on top of the embroidered tissue button 22. After the suture strand 18 is tied, the embroidered tissue button 22 is fixed on top of the tendon 20. The tendon 20 is secured to the bone 14, and the tied suture strand 28 prevents the embroidered tissue button 22 from moving.
Although the embroidered tissue button 22 is disclosed and illustrated as being utilized in shoulder, it is to be understood that the embroidered tissue button 22 can be used in any surgical application. For example, the embroidered tissue button 28 can also be used in a procedure for acromioclavicular repair. Additionally, the embroidered tissue button 22 can also be used to secure a ligament or any soft tissue to bone or can be used in any another joint.
The embroidered tissue button 22 also includes two apertures 30 and 32. In one example, the embroidered tissue button 28 is round. In another example, the embroidered tissue button 28 is oblong. In one example, the apertures 30 and 32 are round. In another example, the apertures 30 and 32 are oblong. In one example, the apertures 30 and 32 together are centered relative to the embroidered tissue button 28.
The embroidered tissue button 28 has a tight mesh, and the embroidered tissue button 28 is less traumatic to the body. The spaces 44 in the embroidered tissue button 28 promote tissue ingrowth and capture between the yarn 46. During healing, the tissue can grow into the spaces 44 in the embroidered tissue button 22, securing the embroidered tissue button 22 in the body and preventing the embroidered tissue button 22 from floating in the body. As the embroidered tissue button 28 does not include any metal, there also is no x-ray artifact.
In one example, the embroidered yarn is polyester yarn. The polyester yarn can have any size or thickness. The largest dimension of the embroidered tissue button 28 is approximately 8 mm.
In this embodiment, a suture strand 40 is threaded through the suture eyelet 38 to secure the tendon 20 to the bone 14. The embroidered tissue button 34 is located above the tendon 20. After threading the suture strand 40 through the tendon 20 and the suture eyelet 38, the suture strand 40 is tied in a knot 42 that is located between the tendon 20 and the embroidered tissue button 34. The embroidered tissue button 34 is fixed on top of tendon 20 to help secure the tendon 20 to the bone 14.
In
The fixation button 48 can be made out of any material. In one example, the fixation button 48 is made out of embroidery or an embroidered yarn. In one example, the fixation button 48 is embroidered from polyester yarn. The slot 58 can be formed by making a cut in the fixation button 48.
In
As shown in
The knot pusher 60 can also be employed with both the embroidered tissue buttons 22 or 34 described above.
The foregoing description is only exemplary of the principles of the invention. Many modifications and variations of the present invention are possible in light of the above teachings. The preferred embodiments of this invention have been disclosed, however, so that one of ordinary skill in the art would recognize that certain modifications would come within the scope of this invention. It is, therefore, to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described. For that reason the following claims should be studied to determine the true scope and content of this invention.
