Description

Achilles tendon minimally invasive anastomat

Technical Field

The utility model belongs to the technical field of bone surgery, concretely relates to achilles tendon minimally invasive anastomat.

Background

Achilles tendon rupture is a clinically common acute injury, and with the increase of physical exercise, the incidence of achilles tendon injury also increases year by year. Current treatments for acute achilles tendon rupture are: non-operative treatment and operative treatment, the non-operative treatment has the defects of high incidence rate of achilles tendon re-rupture, poor strength recovery and the like, and the operative treatment can enable the tendon to be better healed. The surgical treatment commonly comprises open surgery and minimally invasive surgery, the broken end of the achilles tendon can be firmly and reliably sutured, the plantar flexion function of the ankle joint after the surgery is good, the risk of re-breaking the achilles tendon is low, and the occurrence of complications such as incision infection, sural nerve injury and the like is increased. Compared with the traditional operation, the minimally invasive operation can promote the functional rehabilitation of patients more quickly, the complication at the incision is less, and the average hospitalization day is also obviously shortened. Compared with the traditional open surgery, the percutaneous minimally invasive surgery has better clinical curative effect and lower surgical complications.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an achilles tendon minimally invasive anastomat to it has tendon week blood supply to damage big to solve current operation, and the adhesion is more serious, and the complication is many, and the motion function resumes slowly, has the fracture possibility again, probably damages the problem of avoiding the sural nerve moreover.

In order to achieve the above object, the utility model discloses a technical scheme be:

a minimally invasive achilles tendon anastomat comprises a group of rod bodies, wherein one end of each rod body is provided with a handle, the other end of each rod body is provided with a penetrating end, the thickness of the penetrating end is gradually reduced along the direction far away from the rod bodies, the thickness of the farthest end of the penetrating end is 1-2mm, and the penetrating end is provided with a through hole.

The length of the rod body is 15-20cm, and a phi 6 steel bar is adopted.

The penetrating end is 1-1.5cm in width and 3-5cm in length.

The through hole is circular or oval.

The diameter of the through hole is 4-5mm when the through hole is circular.

When the through hole is in an oval shape, the length of the long axis is 7-8mm, and the length of the short axis is 4-5 mm.

The handle is U-shaped, and the head end and the tail end of the handle are close to each other.

The utility model discloses compare in prior art's beneficial effect do:

the utility model discloses a set of body of rod carries out minimal access surgery, has following advantage:

1. small incision, small scar after operation, short operation time and less pain of patients.

2. The puncture end 3 of the blunt achilles tendon minimally invasive anastomat is adopted to establish an achilles tendon suturing channel, so that the sural nerve is prevented from being damaged.

3. By adopting the improved Kessler suture method and the auxiliary suture channel technology, the minimally invasive suture of the Achilles tendon rupture open surgery is successfully realized, and the risks of postoperative complications and recrudescence are reduced.

4. The peritendinous tissue is furthest preserved, the blood circulation around the achilles tendon is protected, the later-stage tissue repair of the achilles tendon and the brake time of the affected limb are further shortened, and the later-stage rehabilitation is facilitated.

5. The simple minimally invasive intrathecal suturing technology takes an Achilles tendon anastomat as a design basis, has small operation wound and is convenient and fast to operate.

6. The achilles tendon minimally invasive anastomat ensures the curative effect of the operation and greatly reduces the medical expenditure of a patient.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

The reference numerals have the following meanings: 1. a rod body; 2. a handle; 3. a penetrating end; 4. and a through hole.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in figure 1, the minimally invasive achilles tendon anastomat comprises a group of rod bodies 1, one end of each rod body 1 is provided with a handle 2, the other end of each rod body is provided with a penetrating end 3, the thickness of each penetrating end 3 is gradually reduced along the direction far away from the rod body 1, the thickness of the farthest end of each penetrating end 3 is 1-2mm, and each penetrating end 3 is provided with a through hole 4.

The length of the rod body 1 is 15-20cm, and a phi 6 steel bar is adopted.

The penetrating end 3 is 1-1.5cm in width and 3-5cm in length.

The through hole 4 is circular or oval.

The diameter of the through hole 4 is 4-5mm when the through hole is circular.

When the through hole 4 is in an oval shape, the length of the long axis is 7-8mm, and the length of the short axis is 4-5 mm.

The handle 2 is U-shaped, and the head end and the tail end of the handle 2 are close to each other.

If no anesthesia contraindication exists, subarachnoid anesthesia and prone position are adopted. Before operation, the broken part of the Achilles tendon is marked, a tourniquet is arranged on the root of the thigh of the affected limb, and a surgical field disinfection drape is used. Making a 3cm long longitudinal incision on the inner side of the broken end of the Achilles tendon, cutting skin, subcutaneous tissues and tendon sheaths, trimming the broken end of the Achilles tendon, and respectively penetrating absorbable suture marks into the tendon sheaths and the broken end of the Achilles tendon for later use. The penetrating end 3 of the achilles tendon minimally invasive anastomat is penetrated from the skin to the far end of the incision, the depth is 2cm, the achilles tendon suture with the needle is penetrated from the outside of the skin to the skin, and then the suture passes through the through hole 4 of the penetrating end of the achilles tendon minimally invasive anastomat and then passes through the middle of the achilles tendon perpendicularly. The penetrating end 3 of the achilles tendon minimally invasive anastomat penetrates into the other side of the far end of the achilles tendon subcutaneously by 2cm in depth, so that the suture passing through the achilles tendon with a needle penetrates through the through hole 4 of the penetrating end of the achilles tendon minimally invasive anastomat on the other side and penetrates out of the skin, the achilles tendon suture is placed in the far end 2cm of the broken achilles tendon at the moment, the subcutaneous achilles tendon minimally invasive anastomats on the two sides are removed, and meanwhile, the achilles tendon. The Achilles tendon suture was also placed 4 cm proximal to the Achilles tendon stump. The ankle joint is enlarged to plantar-flex to reduce the tension of the Achilles tendon, and the proximal side of the Achilles tendon suture at the two sides of the broken end is knotted to the distal side and the inner and outer sides of the Achilles tendon suture at the same time to carry out intra-tendon sheath suture. And then, putting the spare absorbable suture into the broken end of the Achilles tendon originally to tie and reinforce the broken end of the suture, and checking the closed condition of the broken end of the Achilles tendon under direct vision. Finally, the trimmed tendon sheaths are sutured after the incision is irrigated and the wound is closed.
