Abstract

The invention relates to the technical field of machinery, in particular to a minimally invasive incision decompression device for osteofascial compartment syndrome, especially a device for deep fascia minimally invasive incision decompression of a patient with the osteofascial compartment syndrome. The device includes an external tube body and an operation tube body installed in the external tubebody. The minimally invasive incision decompression device drives a transmission tooth to rotate through an adjusting tooth to wind a first pulling rope onto a rotating shaft, so that the two ends ofa connecting strip are fitted to the intermediate position, and two shanks are driven to be attached to the intermediate position to achieve angle adjustment of upset head scissors. A clamping toothof a safety lever is clamped on the transmission tooth, so that the opening angle of the upset head scissors is fixed, and the upset head scissors are prevented from being closed during operation. Anadjusting head is rotated to drive a transmission shaft to rotate, and the position of a holder can be changed by changing the position of a ball screw nut, so that adjustment of the extension lengthof the upset head scissors can be achieved.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a minimally invasive incision and tension reduction instrument for compartment syndrome. Background technique [0002] Compartment syndrome is a series of early symptoms and signs of muscles and nerves in the compartment formed by bone, interosseous membrane, intermuscular septum and deep fascia due to acute ischemia and hypoxia. Also known as acute compartment syndrome and compartment syndrome. Once compartment syndrome is diagnosed, the deep fascia should be incised and decompressed immediately. Early and complete deep fascia decompression is the only effective way to prevent muscle and nerve avascular necrosis. [0003] The existing osteofascial compartment syndrome requires multiple open incisions to reduce tension, the skin incision is large, the trauma is large, and the wound surface oozes blood and oozes a lot. There are no special tools for minimally invasive incis...
