Rat varicocele model building tool and use method thereof

Abstract

The invention discloses a rat varicocele model building tool. The tool comprises a tool body and tool accessories; the tool body comprises a handle and a narrowing rod, the tail end of the narrowing rod is connected with the upper end of the handle through a movable joint, the head end of the narrowing rod is conical, a flexible protective layer is arranged outside the narrowing rod, and a step isarranged on a rod body of the narrowing rod; the tool accessories comprise a ligature and a ligature clamping buckle. The invention further discloses a use method of the rat varicocele model buildingtool. The rat varicocele model building tool and the use method thereof have the following advantages that the ligature is positioned, the phenomenon that due to slipping, the final accuracy is affected is avoided; the rebound diameter can be effectively controlled, and the narrowing effect is more precise; damage to organs can be avoided during operation; knotting is better facilitated, and slippage or tightening can be prevented.

Description

Technical field [0001] The invention belongs to the construction technology of a rat model of varicocele, and specifically relates to a construction tool of a rat varicocele model and a method of use thereof. Background technique [0002] The rat model is used in the study of spermatic vein, and to construct this model, the renal vein of the rat needs to be narrowed, so that figure 1 The left spermatic vein 1 in the middle joins the left renal vein 2. figure 1 3 is the inferior vena cava. At present, the procedure usually uses: self-made a thin metal rod (usually a metal suture needle), place it on the surface of the renal vein 2, and then tie the renal vein 2 and the thin metal rod together (in figure 1 A), and then withdraw the thin metal rod, and then rebound from the renal vein. Due to the restriction of knotting, it cannot rebound to the original diameter, thus achieving the narrowing of the renal vein. After the renal veins are narrowed, the return of the spermatic vein wil...

AI Technical Summary

Problems solved by technology

[0003] However, the above-mentioned traditional operations have the following problems: 1. The specifications of the self-made thin metal rods are not uniform, the rebound diameter is not easy to control, and the narrowing is not precise enough; , It is not easy to control when pulling out, and it is easy to damage the kidneys and large blood vessels; 3. The knot on the thin metal rod is easy to loosen, and it is difficult to grasp it well. to the effect of narrowing
