Description

Skin defect type operation wound gathering and suturing device and operation method thereof

Technical Field

The invention relates to a skin defect type operation wound gathering and suturing device and an operation method thereof, belonging to the field of medical instruments.

Background

Skin tumors are cell proliferative diseases occurring in the skin, and are a common disease. There are many new species of organisms occurring in the intradermal or subcutaneous tissue, and there are clinically benign and malignant tumors. Malignant tumors can proliferate constantly, causing metastases, threatening life, and are called skin cancers.

Skin tumors are dermatological diseases that are currently more difficult to treat, generally refer to benign and malignant tumors that originate in the skin, and mainly include:

1. benign skin tumors: seborrheic keratosis, pigmented nevus, hemangioma, etc.

2. Malignant skin tumor: basal cell carcinoma, squamous cell carcinoma, malignant melanoma, Paget's disease, etc.

3. Cutaneous T-cell lymphoma, mainly consisting of mycosis fungoides: infiltrative plaques, nodules, which occur locally or systemically on the skin, ulceration may occur at a later stage.

4. Other skin tumors: solar keratosis, Bowen's disease, and skin adnexal tumor, manifested as skin spots, plaques, and tumors, with skin lesions persistent and not easy to resolve.

For surgical treatment of skin tumors, the tumor is usually removed by digging out along with surrounding skin tissue, usually leaving a circular wound. Since this wound is a defective wound, it is not suitable for a common suture method, and is generally classified into a method of grafting a skin or a method of implanting a flap to perform a suture. If the skin soft tissue is only defected and no important tendon or bone is exposed, the skin grafting mode can be adopted for treatment, and if the tendon or bone is exposed, a free or local skin flap with a pedicle is adopted to cover the wound surface. The skin grafting has no blood supply and no blood vessel, and the postoperative skin usually generates adhesion and scars and has deviation of wear resistance. The skin flap, no matter carrying or dissociating, has the same structure as the skin of the normal tissue of the human body, and has larger differences in appearance, skin color, texture and flexibility with skin grafting. Both of these methods require skin or flap extraction from healthy skin, not only causing additional trauma and pain, but also the transplanted part is not a hundred percent alive, and needs to be transplanted again once becoming black and necrotic, which seriously leads to wound infection and necrosis and faces the risk of amputation.

For suturing of defective wounds, purse string suturing is now commonly used. However, purse string suturing has its limitations, and it is usually used as a suture method for gastrointestinal tract, which has the advantages of free gastrointestinal tract, strong extensibility, convenient operation and good healing effect. However, the skin is usually not as ductile as the gastrointestinal tract, the suture is easy to tear when the skin is stretched too much, and the purse string suture can only reduce the wound area if the wound area is too large and cannot completely suture. In addition, the irregular purse-string suture stitch results in uneven thickness of the edge of the wound, and even after healing, an unsightly scar is formed, which affects the appearance.
