Problems solved by technology

However, the stapler only has 3 guide pin holes, and it uses the figure-eight suture method, which often requires a large number of sutures to be located around the Achilles tendon. The suture strength and soft tissue irritation around the tendon are still issues worth noting.

Embodiment 1

[0021] Such as Figure 1 to Figure 3 As shown, a guide device for repairing Achilles tendon rupture includes a double U-shaped Achilles tendon aimer and a puncture needle guide with wire slots; the double U-shaped Achilles tendon aimer includes a first body 1 and a second body 2, which are U-shaped respectively. The first body 1 and the second body 2 include a base and two inner positioning rods 3 and outer positioning rods 4 extending upward from both sides of the base. The base surfaces of the first body 1 and the second body 2 are respectively provided with a 30-degree angle for holding the slope; the base of the first body 1 and the second body 2 are connected by adjusting bolts 5, two guide rods 11 are set between the bases of the first body 1 and the second body 2, and the adjustable bolts 5 are strengthened Fixed, the two inner positioning rods 3 adjacent to the first body 1 and the second body 2 are designed to be inclined, and the two inner positioning rods 3 fit toge...

Abstract

The invention belongs to the field of medical minimally invasive achilles tendon repairing apparatuses for the orthopedics department, and particularly relates to an achilles tendon rupture repairingand guiding device. The achilles tendon rupture repairing and guiding device comprises a dual-U-shaped achilles tendon sighting device and a trunking puncture needle guiding apparatus, the dual-U-shaped achilles tendon sighting device comprises a first body and a second body, each body comprises a base part and two inner-side locating rods and outer-side locating rods which are upwards extended from the two sides of the base part; the base parts of the two bodies are connected through adjusting bolts, the four locating rods are accordingly provided with locating holes respectively, and the trunking puncture needle guiding apparatus comprises an achilles tendon near-end puncture device and an achilles tendon far-end puncture device. A trunking puncture needle plays an effect of a suture guiding apparatus after conducting puncturing according to the locating holes, by adjusting different angles, typical Kessler and Bunnell suturing of the achilles tendon is completed, so that a suture isarranged in the core of the achilles tendon, the suturing strength is guaranteed, and irritation of surrounding tissues due to exposure of the suture is avoided; the surgical operation is simple, thetrauma is small, and the risks of complications like the sura nerve injury, cutaneous necrosis and infection can be obviously reduced.

Description

technical field [0001] The invention belongs to a medical orthopedic minimally invasive Achilles tendon repair instrument, in particular to a guide device for Achilles tendon rupture repair. Background technique [0002] The Achilles tendon is the thickest tendon in the human body, and it is also one of the tendons with the highest incidence of rupture. It is mostly caused by sports injuries and is a common disease in orthopedics. The treatment methods include conservative treatment and surgical treatment. After conservative treatment, the occurrence rate of Achilles tendon re-rupture is high, and plantarflexion weakness is prone to occur, which seriously affects the patient's function. Although the traditional incision can reliably fix the Achilles tendon, extensive exposure will cause great damage to the blood supply of the Achilles tendon and peritendon tissue, which is prone to Achilles tendon adhesion and delays the healing of the Achilles tendon. Postoperative pain a...
