Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to an intelligent skin stretcher. Background Art

[0002] Tension wounds (incisions) caused by various reasons are common, such as traumatic skin defects caused by severe trauma, skin defects after large-area burn scar excision and repair, skin defects after resection of huge benign (malignant) tumors on the body surface, skin defects in the donor area of ​​flaps (slices), chronic and refractory wounds, wounds after incision and decompression of compartment syndrome, skin defects after internal fixation of severe open fractures and chronic osteomyelitis, etc. Such wounds (incisions) are difficult to suture directly due to the large number of skin defects and high skin tension.

[0003] At present, clinical experts in related fields at home and abroad are actively exploring and innovating, and have developed a number of surgical instruments designed to stretch the wound (incision) skin and reduce the tension of the wound (incision) skin, such as TopClosure skin stretcher, skin stretcher, pull-rod wound skin expander, etc. The application of these instruments has solved the problem that large wounds (incisions) cannot be sutured in the first stage due to excessive skin tension. However, they all have the disadvantages of requiring continuous manual intervention and management, the inability to accurately control the traction force and time, and many complications (skin cutting effect, ischemic necrosis), which not only affect the traction effect, but also restrict the clinical application and promotion of this technology.

The rotor of the electric device 304 is connected to the gear 303. The gear 303 is located between the first pulling rack 400 and the second pulling rack 500. The gear 303 contacts the first pulling rack 400 and the second pulling rack 500.
