Description
Technical Field
The utility model relates to the technical field of medical equipment, in particular to a stringy kirschner wire for treating malformation of hammered finger by reconstructing extensor tendon stop.
Background
The hammer finger is a bent deformity of the distal interphalangeal joint caused by the limitation of extension of the distal interphalangeal joint of the finger due to the rupture or avulsion of the extensor tendon in the area I of the extensor tendon of the finger. Hammer refers to a common and frequently occurring disease in hand surgery, which is caused by direct violence due to trauma. Because the tendon tissue of the distal interphalangeal joint is weak, the position is superficial, and the peripheral blood supply of the tendon is poor, the healing effect of the tendon after reluctant repair is poor, and the movement limitation or relapse of the distal interphalangeal joint is easy to occur. How to effectively reconstruct the extensor tendon insertion point and reduce postoperative complications becomes a hot spot for research of surgeons.
Treatment with hammer fingers includes both conservative and surgical treatment. Conservative treatment generally adopts splints, brace supports and the like, bends the proximal interphalangeal joint by 60 degrees, slightly stretches the distal interphalangeal joint, and fixes the affected finger for at least 6 weeks. However, it fails to work due to the external fixation brace being easy to loosen, long treatment time, and the retraction of the tendon ends of the extensor muscles. The surgical treatment comprises first-stage surgical repair of the original anatomical structure and restoration of the balance of the flexion and extension forces of the joint, and second-stage surgical repair can be performed if conservative treatment fails. Based on the poor effect of conservative treatment and the improvement of the expectation of the curative effect of patients, with the development of internal fixation, surgical treatment hammer finger gradually becomes the main treatment means. In recent years, the tendon fixing direct suture method, the pure kirschner wire fixing method, the crossed kirschner wire fixing method and the suture anchoring implantation method are commonly used. The direct sewing has poor sewing strength, and is easy to tear off to cause secondary fracture; the kirschner wire fixation is easy to cause risks of loosening, fixation failure, limited back stretching and the like due to improper fixation; the bone anchor has good effect with suture, but is easy to cause postoperative complications such as internal fixation failure caused by postoperative loosening and prolapse.
In view of this, a new and desirable surgical instrument is needed.

Detailed Description
The following detailed description of the present invention is provided to facilitate further understanding of the invention.
Fig. 1 is a schematic view of a kirschner wire with a wire for reconstruction of extensor tendon insertion points to treat mallet finger deformities. As shown in the figure, the utility model discloses a take line ke shi needle, including ke shi needle 1, ke shi needle 1 is provided with two strands of tendon stylolite 2 in the horizontal section, and each tendon stylolite 2's tip all is provided with round needle 3.
Further, the tendon suture is 3-0 tendon suture with a round needle. The preferred tendon suture is 30cm long. The Kirschner wire 1 has a length of 3mm and a diameter of 1 mm. The two tendon suture threads 2 are 1mm apart on the kirschner wire and 1mm apart from the two ends of the kirschner wire.
Further, the ends of the two tendon suture threads 2 are embedded in the k-wire 1.
The utility model discloses a use method of taking line kirschner wire as follows:
(1) punching and establishing a bone tunnel: drilling a Kirschner wire with the common diameter of 1.2mm into the dorsal base of the distal phalanx to penetrate out of the phalanx, and drilling a bone tunnel in an oblique manner;
(2) threading the kirschner wire with the wire from the bone tunnel: penetrating the novel kirschner wire with the wire into the ventral side from the dorsal bone tunnel;
(3) blocking the band wire kirschner wire on the ventral side: the tendon suture is left on the dorsal side and is tensioned to enable the kirschner wire to be in a transverse state and be blocked on the ventral side;
(4) tendon suture extensor tendon proximal end: the tendon suture is used for suturing the proximal end of the extensor tendon to reconstruct a dead point, the two ends of the suture are respectively and symmetrically inserted from the broken end of the tendon to the proximal end, the suture is withdrawn by about 5mm, then passes through the tendon transversely, and the two ends of the suture are knotted at the dorsal side of the tendon. The proximal end of the extensor tendon was sutured and tied off dorsal to the tendon.
(5) The hyperextension of the distal interphalangeal joint is kept at 5-10 degrees by fixing a common kirschner wire with the diameter of 1.0 mm.
Clinical research shows that compared with the traditional treatment method, the application has the advantages of simple operation, firm fixation, lower cost, fewer postoperative complications and better treatment effect.
Although the present invention has been described with reference to the above embodiments, it is not intended to limit the present invention, and various alternatives and modifications can be made by those skilled in the art without departing from the spirit and scope of the present invention.
