Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, and in particular to a special wire-passing device for percutaneous minimally invasive repair of Achilles tendon. Background Art

[0002] The Achilles tendon is a tendinous structure that extends from the lower end of the belly of the triceps surae, namely the gastrocnemius and soleus muscles, and ends at the calcaneal tuberosity. It is one of the thickest and largest tendons in the human body, and is of great significance for the body's walking, standing and maintaining balance. Achilles tendon rupture is a relatively common injury in foot and ankle surgery, and often occurs during training exercises such as running and jumping. After the injury, the patient loses the calf bouncing power, which affects the motor function. Achilles tendon repair is usually required, and the sutures need to be connected and repaired using a thread guide.

[0003] However, the existing dedicated wire guide for percutaneous minimally invasive repair of Achilles tendon has the following disadvantages:

[0004] (1) The injured area usually needs to be cut open with a scalpel to fully expose the Achilles tendon and then anastomosed and repaired, which may sometimes lead to complications such as wound infection, necrosis, Achilles tendon exposure, and long-term adhesion.

[0005] (2) The depth of needle insertion needs to be controlled by medical staff based on experience, which may easily lead to repair failure due to the needle insertion being too deep or too shallow.

[0006] Therefore, the utility model provides a special wire-passing device for percutaneous minimally invasive repair of Achilles tendon. Utility Model Content

[0007] 1. Technical issues to be resolved

[0008] The technical problem solved by the utility model is to provide a special thread passer for percutaneous minimally invasive repair of Achilles tendon, which is highly practical, can be simply operated and has a relatively simple structure. It solves the problems proposed in the above-mentioned background technology that complete exposure and anastomosis of the Achilles tendon may sometimes lead to complications such as incision infection and necrosis, and the needle insertion depth is difficult to control.

[0009] (II) Technical solution

[0010] To achieve the above objectives, the utility model is implemented through the following technical solutions: a special wire passer for percutaneous minimally invasive repair of Achilles tendon, comprising a thin steel tube, the outer diameter of the thin steel tube is 1.5 mm, the inner diameter of the thin steel tube is 1.0 mm, a suture thread runs through the inside of the thin steel tube, the inner wall and the outer wall of the thin steel tube are both smoothly designed, the inflected mouth of the thin steel tube is smoothly designed, the puncture edge of the thin steel tube is round and blunt, and the surface of the thin steel tube is provided with scale lines.

[0011] Optionally, the thin steel tube is made of stainless steel and is ground and polished. The grinding and polishing ensures the smoothness of the thin steel tube, which is beneficial for the flexion and sliding of the Achilles tendon line.

[0012] Optionally, the thin steel tube is designed to be in a long arc shape, and electrochemical polishing is used at the long arc-shaped inflection point, and the electrochemical polishing ensures the smoothness of the long arc-shaped inflection point.

[0013] Optionally, the scale lines are evenly distributed from top to bottom on the surface of the thin steel tube, and the scale line spacing is mm. The setting of the scale lines ensures the accuracy of the needle insertion depth.

[0014] Optionally, the length of the thin steel tube is 120 mm, and the long diameters at both ends of the thin steel tube are 2.5 mm.

[0015] Optionally, both ends of the thin steel tube are provided with threading holes, and the surface of the threading holes is smooth and not sharp. The smooth and non-sharp surface of the threading holes can avoid puncturing important structures such as blood vessels and nerves.

[0016] (III) Beneficial effects

[0017] The utility model provides a special thread-passing device for percutaneous minimally invasive repair of Achilles tendon, which has the following beneficial effects:

[0018] 1. The dedicated wire guide for minimally invasive percutaneous repair of Achilles tendon is provided with a thin steel tube with an outer diameter of 1.5 mm and an inner diameter of 1.0 mm. The inner and outer walls and the folded opening are smooth, which is conducive to the folded sliding of the Achilles tendon line. The puncture blade of the thin steel tube is round and blunt to avoid puncturing important structures such as blood vessels and nerves. The thin steel tube is designed in a long arc shape to ensure that it can cross the effective distance of the Achilles tendon stump for suture repair. It can be done with only a needle hole but no large incision. The stump and the perianal membrane can be repaired with an auxiliary small incision, which not only solves the problem of incision infection and necrosis in traditional open surgery, but also eliminates the problems of nerve damage, skin and deep adhesion that are prone to occur in minimally invasive treatment of Achilles tendon.

[0019] 2. This special thread guide for percutaneous Achilles tendon minimally invasive repair can help doctors understand the depth of needle insertion through the setting of scale lines, avoiding the failure of repair caused by the needle insertion being too deep or too shallow.

Since the inner and outer walls and the folded mouth of the thin steel tube 1 are smooth, it is conducive to the folding and sliding of the Achilles tendon line. The puncture edge of the thin steel tube 1 is blunt to avoid puncturing important structures such as blood vessels and nerves. The thin steel tube 1 is designed in a long arc shape to ensure that it can cross the effective distance of the Achilles tendon end for suture repair;

[0035] Step 2: When performing puncture, observe scale line 3. Scale line 3 can help the doctor understand the depth of needle insertion and avoid the situation where the repair fails due to the needle insertion being too deep or too shallow.
