Description

Bifilar surgical suture needle

Technical Field

The utility model belongs to the technical field of the medical appliances technique and specifically relates to a twin line surgical suture needle.

Background

The holding force suitable for the double-strand single-locking surgical knot is necessary for maintaining wound apposition and ensuring tissue healing. Knot unraveling can lead to serious complications, especially for some high tension suturing procedures, such as tendon repairs, and recently has even been reported to be as high as 86%. To solve this problem, it is generally recommended to increase the number of knots, however, as the number of knots increases, a larger lump of foreign matter is formed, which itself encroaches on some space. For example, in the repair of flexor tendons, the space of the tendon sheaths is relatively fixed and it is difficult to accommodate the larger knot. And the large knot as a foreign body also affects the healing process of the tendon, reducing the repair strength. In order to improve the strength of the knots and reduce the number of knots, Chunfeng ZHao professor in Mayo medical center has designed a new knotting method, which consists of three knots: double-strand unijunctions add two common unijunctions, namely double-strand single-locking junctions (TSOL). And mechanical properties of different suture materials and knotting methods are evaluated, and relevant conclusions are published on the recent JBJS.

Figure 5 illustrates a knotting method for TSOL junctions. The needle holder starts under the two sutures, winds 360 degrees (1), then holds the proximal suture (the ends of the two sutures) (2) with the needle holder, inserts forceps before the needle holder withdraws the coil, holds the looped coil open, and slides the coil to the base to tie off (3). If the loop is tightened (closed), the knot cannot be slid into place adjacent the tissue being sutured. If the tension of the knot is not high, the assistant holds the knot in place and then withdraws the forceps to close the loop and knot (4 a). In addition, if a suture material with a relatively hard friction is used, such as a braided composite polymer (braided polyblend), after the first double single knot is made, the two sutures may be pulled in opposite directions to tighten the knot (4 b). After the first double-strand unijunction is drilled, two single-strand unijunctions, namely TSOL junctions (F), are drilled.
