Description

A line body for soft tissue is fixed

Technical Field

The utility model relates to the field of medical equipment, especially, relate to a line body for soft tissue fixation.

Background

The most of the soft tissue injuries are complete or partial detachment of tendons, ligaments or other soft tissues from bones, which mainly occur in joints of human bodies, and the injuries caused by hyperkinesia or over-stress of the soft tissues along with aging usually need surgical operations. A common form of repair currently used in surgery is the use of a suture anchor device to secure the detached soft tissue to the bone.

For example, the rotator cuff tissue is a complex of a set of tendons that wraps around the head of the humerus and plays an extremely important role in maintaining the stability and movement of the shoulder joint. Surgical treatment of rotator cuff injuries has evolved over the years from open surgery to arthroscopic shoulder treatment. The sleeves were sutured and repaired under arthroscopy by using a suture anchor. Through research and research for many years, the surgical techniques comprise a bone-through suture technique, a single-row technique, a double-row technique and the most advanced suture bridge technique at present. The suture bridge technology is characterized in that the operations of traction reduction, knotting fixation, suture pressing and the like are carried out on the rotator cuff by utilizing the inner row and the outer row of band wire anchors so as to restore the anatomical position of the rotator cuff, promote the healing of the tendon bones and restore the physiological function of the rotator cuff. At present, shoulder arthroscopy technology is not popularized in all levels of hospitals in China yet and belongs to high-difficulty arthroscopy operation. The technology has long learning period, complex operation and large difference of postoperative effects. The arthroscopic repair of rotator cuff injury needs to apply a suture anchor, however, although the existing suture anchors have various brands, the functions are different, the suture management in the operation is very complicated, and doctors can only master the suture anchor after long-term training and practice. The problems of no healing and secondary fracture of the rotator cuff after surgical suture are still rare. The reason for this is that, in addition to iatrogenic reasons, there is a direct relationship with suture anchor design and suture technology, and even though the current suture bridge technology is developed, the effect is still not as good as possible.

The key points of the rotator cuff operation are as follows: 1. resetting the rotator cuff to enable the shortened rotator cuff to return to fully cover the original dead point; 2. the rotator cuff can be in close contact with the bone bed, which is a precondition for healing; 3. the suture fixation is strong, and the rotator cuff is prevented from being fixed and failing before healing and being torn off again. According to the design of a common anchor with a thread for a rotator cuff at present, the tip is a threaded nail head, the nail head is provided with a perforation or a pulley design and is connected with one or two slidable threads, the tail ends of the threads are separated, the tail of the same thread can be pulled to freely slide, and operations such as knotting, sewing and the like can be performed. The method comprises the steps of screwing an anchor into a proper position of an original stopping point bone bed of the rotator cuff by an arthroscope operation, penetrating a tail of a thread through the rotator cuff to the upper surface by a suture instrument, suturing the torn rotator cuff by knotting, performing traction reduction on the shortened rotator cuff, and finally pressing all suture threads to the surface of the rotator cuff by a row of nails to reduce the rotator cuff and contact the bone surface (figure 1) so as to achieve the possibility of healing the tendon and bone. This method is an improvement over single row fixings, but still suffers from certain drawbacks. 1. The suture cuts the traction of the rotator cuff, and particularly for the old patients with poor rotator cuff quality, the suture can be torn, so that the fixation fails; 2. the operating space under the acromion is limited, the suture needs to carry out multi-point repeated puncture and suture on the rotator cuff, the operation is complicated, the operation is difficult, and the suture is also a damage to soft tissues and the rotator cuff; 3. the pressing rotator cuff is of a single point or linear structure, the contact area of the rotator cuff and a bone bed is small, large-area pressing force is not generated on the edge of the rotator cuff, the edge of the rotator cuff is easy to be turned up, or cat ears are formed, and the rotator cuff is not favorable for healing.
