Intelligently-regulated skin stretching closer

Abstract

The invention discloses an intelligently-regulated skin stretching closer. The intelligently-regulated skin stretching closer is characterized in that a stretching unit composed of a central stretching module A and stretching modules on the two sides and arranged on a connecting plate and another stretching unit composed of a central stretching module B and stretching modules on the two sides andarranged on the connecting plate are adopted, wherein the central stretching module A and the stretching modules on the two sides and the central stretching module B and stretching modules on the twosides are arranged on the connecting plates; and the two stretching units are connected through a T-shaped pull rod to form the H-shaped skin stretching closer. Compared with the prior art, the intelligently-regulated skin stretching closer has the advantages that no secondary trauma exists, scars are minimized, the epidermis healing effect is perfect, the stretching force is monitored in real time, the stretching force is accurately controlled to be at a stable safety level, the best stretching closing effect is achieved, complications such as skin necrosis are reduced, the situation that thestretching effect is affected due to the fact that the hard stretching force is too large or too loose is effectively prevented, and the intelligently-regulated skin stretching closer can adapt to different curved surface wounds during installation, is good in attaching protection performance and simple in structure and has wide application prospects in medical suturing.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary devices, in particular to a closer for intelligently regulating skin stretching suitable for orthopedic surgery. Background technique [0002] At present, the method of using the elasticity of the skin to pull to close the wound and repair the skin defect is more commonly used in clinical practice. This method uses instruments to assist in pulling, apposition, locking and maintaining moderate extrusion of the apposition skin edges on both sides. to promote the natural healing of the skin. At present, there are two main types of this device: one is temporary, rapid and repeated stretching during the operation to suture the wound after the skin is loosened, such as the skin stretcher made in Germany, which uses hook feet to hook both sides of the skin and pulls it through a connecting rod , the traction force is large, because it is a temporary application during the operation, the elasti...

AI Technical Summary

Problems solved by technology

The two key parts of this type of device are the skin fixation part and the tension closure part on both sides of the wound. Different products have different designs. The fixation part is generally adhered to the skin through adhesive materials. There are skin allergies; some products are fixed by skin nails, and their strength and depth are not enough; some are inserted into the skin on both sides by steel needles, which have greater strength, but the trauma is large and it is difficult to apply to irregular wounds

The tension closure components mainly include plastic toothed pull buckles, elastic rubber belts, etc. The tension force is small, and the tension force of the threaded rod is large, but the direct mechanical force is difficult to adjust and cannot be quantified, and it is easy to appear too loose. Complications that affect the stretching effect or cause skin ischemia and necrosis due to overtightening

[0003] The skin stapler in the prior art cannot accurately monitor and control the pulling force, including the pulling force of a single device or the balance of pulling force between multiple devices, all rely on the operator's feel to adjust the tightness, which is prone to Excessive pulling force will lead to skin necrosis or deep muscle ischemic necrosis, and too small pulling force will lead to a decrease in the efficiency of wound closure, and when multiple devices are applied at the same time, the unbalanced pulling force of each device will also lead to the above two unfavorable factors appearing at the same time, thus Affect the treatment effect
