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

Abstract

The invention relates to a skin defect type surgical wound gathering and suturing device and an operation method thereof, and belongs to the field of medical instruments. The skin defect type surgicalwound gathering and suturing device comprises an edge sealing mechanism and a tightening mechanism, wherein the edge sealing mechanism comprises a spiral spring, and a sharp needle sleeves the head end of the spring; the tightening mechanism comprises an outer cylinder, wherein an inner rod matched with the inner part of the outer cylinder, lower holes are evenly distributed in the lower part ofthe outer cylinder in the circumferential direction, annular lower grooves are formed in the inner rod and correspond to the lower holes in positions, lower thin wires are respectively arranged in thelower holes, the inner ends of the lower thin wires are fixed to the lower grooves of the inner rod, and all the lower thin wires are equal in lengths. Small hooks are fixed to the end of the lower thin wires, stand rods are fixed to the upper end of the outer cylinder, reeds are vertically and respectively fixed on the stand rods, each gear is coaxially fixed on the corresponding inner rod, andeach gear is matched with the corresponding reed. Skin or skin flaps do not need to be transplanted, extra wounds cannot be caused, a skin cancer surgical wound is sutured in a slow advancing mode, the healing period is reasonably adjusted according to the self-healing capacity of a human body, stitches are uniform and regular, scars are not obvious after healing, the stitches are small in stress,and tearing is not liable to happen.

Description

technical field [0001] The invention relates to a skin defect surgical wound gathering and suturing device and an operating method thereof, which belong to the field of medical instruments. Background technique [0002] Skin tumor is a cell proliferative disease that occurs in the skin and is a common disease. There are many types of neoplasms that occur in the intradermal or subcutaneous tissue, clinically divided into benign tumors and malignant tumors. Malignant tumors can continue to proliferate, cause metastasis, and threaten life, which is called skin cancer. [0003] Skin tumors are currently difficult to treat dermatological diseases. They generally refer to benign and malignant tumors that originate in the skin, mainly including: [0004] 1. Benign skin tumors: seborrheic keratosis, pigmented nevus, hemangioma, etc. [0005] 2. Malignant skin tumors: basal cell carcinoma, squamous cell carcinoma, malignant melanoma and Paget's disease. [0006] 3. Cutaneous T-ce...

Problems solved by technology

However, the skin is usually not as extensible as the gastrointestinal tract. Excessive stretching can easily lead to tearing of the suture. If the wound area is too large, the purse string suture can only reduce the wound area, but cannot be completely sutured.

In addition, irregular purse string suture stitches lead to uneven thickness of the wound edge, which will form unsightly scars even after healing, affecting the appearance
