Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical auxiliary apparatus, and particularly relates to a surgical traction device for general surgery department. BACKGROUND

[0002] The surgical traction device is a key surgical auxiliary tool for exposing the operation field, reducing intraoperative injury and improving operation accuracy by mechanically pulling or fixing tissues. In radical gastrectomy, the liver and transverse colon need to be retracted to expose the posterior wall of the stomach to avoid injury to the spleen or pancreas. In colon cancer surgery, the S-shaped retractor is used to retract the lateral peritoneum to clearly expose the inferior mesenteric vessels and reduce the risk of bleeding. In abdominal surgery, the wet saline gauze pad is used in combination with the retractor to prevent the intestine from flowing into the operation field and reduce the incidence of intestinal adhesion.

[0003] The traction range of conventional traction devices is usually determined by the size and shape of the device, which cannot be dynamically adjusted to a larger range according to the surgical needs. If a large abdominal retractor is used for a superficial wound, the surrounding tissues may be excessively pulled due to the large size of the device, increasing unnecessary injury. If a small thyroid retractor is used for a deep operation field, it may not be able to fully expose the deep structure due to insufficient traction force or limited range, increasing the difficulty and risk of surgery. In addition, the traction device usually fixes the tissues by continuous pressure, and long-term traction may cause ischemia, increase anaerobic metabolism of tissues, accumulate lactic acid, and further aggravate cell damage. Therefore, the surgical traction device for general surgery department is proposed. SUMMARY
