Minimally invasive traction bar

Abstract

The invention discloses a minimally invasive traction bar, and relates to the technical field of medical surgical instruments. The minimally invasive traction bar comprises a bar body and a chuck, wherein the chuck is connected with the lower end of the bar body through a clamping connection mechanism; the upper end of the bar body is a smooth curved surface; more than two through holes which run through the bar body along the axial direction are formed in the bar body; the through holes are uniformly distributed and arrayed along a center line, which serves as a center shaft, of the bar body; the upper ends of the through holes extend to the outer side of the bar body and are communicated with an exposed oblique groove in the periphery of an upper portion of the bar body; more than two steel wires are fixed on the upper end surface of the chuck and respectively penetrate in the through holes of the bar body; the upper ends of the steel wires extend out of the bar body along the groove; gauze wound at the upper end of the bar body can be clamped tightly; and a gauze locking structure is also arranged on the upper section of the bar body. The gauze wraps the upper section of the bar body; the steel wires are inserted in the through holes of the bar body; while the chuck is pushed towards the bar body, the upper ends of the steel wires extend out of the bar body along the through holes and the groove; and the gauze is firmly fixed under the clamping effect of the two steel wires. By the minimally invasive traction bar, tissue is convenient to drag, the surgery operation speed is increased, and the safety degree is improved.

Description

technical field [0001] The invention relates to the technical field of medical operation instruments. Background technique [0002] Adequate exposure of the surgical field of view is one of the important factors determining the success of the operation. During some surgical procedures, bodily tissues such as organs may block the areas the surgeon needs to reach during the procedure. Traditionally, retractors are used in surgical operations, and different shapes of retractors are used as retractors according to different operations, so that the surgical site can be exposed well. But with the development of minimally invasive technology, the surgical incision is getting smaller and smaller, and the retractor is obviously not suitable for minimally invasive surgery such as laparoscopic or endoscopic surgery. [0003] Laparoscopic surgery is a minimally invasive surgery in which the surgeon guides the operation of surgical instruments by inserting a small light source through ...

AI Technical Summary

Problems solved by technology

However, in laparoscopic surgery, the surgical incision is too small to conveniently deliver the gauze to the traction site, and when the tissue to be stretched is deeper than the incision, it is even more difficult to deliver the gauze, which makes the surgical field of vision unclear. Prolong the operation time and increase the operation risk
