Description

Technical Field

[0001] This utility model provides a surgical instrument for repairing diabetic foot wounds. It belongs to the field of medical instrument technology. Background technology:

[0002] Diabetic foot refers to a disease state in diabetic patients where ulcers and gangrene occur due to decreased lower limb protective function caused by neuropathy, and insufficient arterial perfusion caused by macrovascular and microvascular lesions, leading to microcirculatory disorders. It is one of the important causes of disability and even death in diabetic patients, causing not only pain to patients but also a huge economic burden.

[0003] Not all diabetic patients will develop diabetic foot. It is only when the condition progresses to a more severe stage that symptoms such as intermittent claudication, rest pain, and gangrene of the extremities appear.

[0004] The symptoms and signs of diabetic foot vary depending on the course and severity of the disease. Mild cases may only present with mild foot pain and superficial skin ulcers; moderate cases may present with deeper penetrating ulcers and soft tissue inflammation; severe cases may present with soft tissue abscesses, bone lesions, localized gangrene of the toes, heel, or dorsum of the foot, and in some cases, gangrene of the entire foot may occur.

[0005] There are many methods for classifying diabetic foot, including the Wagner method, the TEXAS classification and staging, and the Chinese Medical Association's classification of diabetic foot, which share the same principles and similar methods.

[0006] The Wagner method, which grades patients' conditions according to their severity, is widely accepted and is divided into 0 to 5 levels.

[0007] Grade 0: This refers to individuals with risk factors for developing ulcers.

[0008] Grade 1: Ulcers on the surface of the foot, but without signs of infection. Ulcers commonly occur on protruding parts of the foot, such as the heel, sole, or foot, and are often surrounded by calluses.

[0009] Grade 2: Characterized by deep penetrating ulcers, often accompanied by soft tissue infection, but without osteomyelitis or deep abscess.

[0010] Grade 3: Deep ulcers often affect bone tissue and may involve deep abscesses or osteomyelitis.

[0011] Grade 4: Characterized by ischemic ulcers with gangrene, often accompanied by neuropathy without severe pain, and infection may be present on the surface of the necrotic tissue.

[0012] Grade 5: Gangrene affects the entire foot; the lesions are extensive and severe, and some develop rapidly.

[0013] Western medical treatment for diabetic foot:

[0014] (1) General treatment: In addition to strictly controlling blood sugar and improving overall health, it is necessary to eliminate some known risk factors for vascular diseases, such as treating hypertension, lowering blood lipids, and quitting smoking.

[0015] (2) Eliminate edema: As long as there is edema, all ulcers will not heal easily, regardless of the cause of the ulcer. Diuretics can be used for treatment.

[0016] (3) Treatment of neuropathic foot ulcers: 90% of neuropathic foot ulcers can heal with conservative treatment. The key is to reduce the pressure load on the foot. This can be achieved by using special pressure-altering orthotic shoes or foot orthoses to change the pressure on the patient's foot.

[0017] In addition, the frequency of dressing changes and the amount of topical medication should be determined based on the depth, size, amount of exudate, and whether there is a concurrent infection.

[0018] (4) Management of ischemic lesions: If there is no indication for surgery for vascular occlusion, conservative treatment can be adopted, such as intravenous infusion of vasodilators and drugs that improve blood circulation, such as tanshinone, ligustrazine, heparin, etc.

[0019] For patients with insufficient blood supply to the feet, angiography should be performed after infection control, followed by vascular reconstruction. Vascular reconstruction can promote ulcer healing, relieve pain, improve lower limb function, and enhance quality of life.

[0020] Amputation is a viable option when various treatments fail or when not amputating would threaten the patient's life. Based on angiography or Doppler ultrasound results, the lowest possible level of the lower limb should be amputated to preserve as much function as possible. Even after unilateral amputation, there is still a possibility of ulceration or gangrene developing on the other side; therefore, patients must be educated about foot protection.

[0021] (5) Treatment of infection: Patients with foot infections, especially those with osteomyelitis and deep abscesses, should undergo intensive insulin therapy while monitoring blood glucose levels to bring blood glucose to or near normal levels. Appropriate antibiotics should be selected based on bacterial culture results and drug sensitivity tests.

[0022] (6) Surgical treatment: Refractory ulcers can be treated surgically. When diabetic foot infection or gangrene affects most or the middle part of the foot, the surgeon must choose between major amputation or conservative treatment as much as possible.

[0023] Debridement: Most advocate thorough debridement, incision and drainage of the infected lesion, and debridement should extend to healthy tissue with bleeding. All necrotic tissue should be removed, and vital tendons and ligaments should be protected as much as possible. Gangrenous lesions with small openings and large cavities should have enlarged incisions. Polycystic abscesses should have multiple incisions to maintain unobstructed drainage.

[0024] Treatment of local blisters and blood blisters should be carried out under strict disinfection. A sterile syringe should be used to aspirate the contents of the blisters from the lowest point, and 2.5% iodine solution should be applied to the area to prevent infection. Appropriate pressure should be applied to the area to make it dry up.

[0025] Wound management: Change dressings daily. Locally, clean and apply a mixture of antibiotics, insulin, and anisodamine (654-2) (e.g., 250-500 ml of 5% saline, 40 U of human insulin, 240,000 U of gentamicin, or other antibiotics and 40 mg of anisodamine (654-2) injection). Insulin can improve the function of white blood cells, stimulate the growth of epithelial cells and fibroblasts, and promote protein synthesis, which is beneficial to wound healing. Local application of antibiotics can enhance the anti-infection effect. Local application of anisodamine (654-2) can improve blood circulation. During the day, keep the wound exposed as much as possible without bandaging. At night, bandaging can be used to avoid further damage. Traditional Chinese medicine powder can be used to promote tissue regeneration, reduce inflammation and pain, and improve microcirculation. Mechanical padding can reduce the weight-bearing on the ulcer site. Bed rest and the use of special shoes are also recommended. In addition, local irradiation with a Zhoulin spectrum instrument or light bulb can help keep the wound dry and improve blood circulation. Each session should last half an hour, 3-4 times a day. Elevating the affected limb can help reduce local edema (ulcers of any cause are difficult to heal if there is edema). Diuretics can be used if necessary.

[0026] Traditional wound care requires frequent changes of scalpels, tissue scissors, and curettes due to the varying structure and nature of wounds. This makes the treatment process inconvenient, inefficient, and time-consuming, necessitating a composite surgical instrument. Currently, while scalpels, tissue scissors, and curettes can clean wounds, their precision and speed need improvement in the complex treatment of diabetic foot wounds. A dedicated, integrated composite instrument warrants further research and development. Summary of the Invention:

[0027] In view of this, the present invention provides a diabetic foot wound repair device, which utilizes the file, blade tip and side blade on the repair device head to achieve convenient cutting, smoothing and rinsing of the wound. The shape and specifications of the repair device can be diversified according to different parts of the patient, making the operation light and convenient, and enhancing the practicality of the product.

[0028] To solve the above problems, the present invention adopts the following technical solution:
