Problems solved by technology

The clamp head is generally made of stainless steel, and is equipped with a tooth structure to prevent the blood vessel from falling off. If the clamping force is too small, the blood flow cannot be effectively blocked, and if the clamping force is too large, it is easy to damage the blood vessel.
In addition, the volume of the vascular blocking forceps is too large to occupy a certain operative field, which affects the operation

Abstract

The invention relates to a split type noninvasive magnetic blood vessel blocking device and belongs to the technical field of medical apparatuses and instruments. The split type noninvasive magnetic blood vessel blocking device comprises a pair of blocking strip feeding forceps, a blocking strip I and a blocking strip II. The blocking strip I is connected to one forceps jaw of the blocking strip feeding forceps, the blocking strip II is connected to the other forceps jaw of the blocking strip feeding forceps, one side of the blocking strip I has magnetism, one side of the blocking strip II hasmagnetism, and the blocking strip I and the blocking strip II can attracted with each other in a clamping state of the blocking strip feeding forceps. After the blocking strips are clamped on the blood vessel by using the split type noninvasive magnetic blood vessel blocking device, the blocking strip feeding forceps can be taken away, and it can be achieved that the surgical operation is not affected and a surgical view field is widened.

Description

technical field [0001] The invention relates to a split-type non-invasive magnetic blood vessel blocking device, which belongs to the technical field of medical instruments. Background technique [0002] Some surgical procedures require the use of vascular blocking forceps to clamp blood vessels to block blood flow and perform surgical procedures. Most of the currently used vascular blocking forceps are made of stainless steel, including a pliers head, a pliers handle, and a handle. The clamp head is generally made of stainless steel, and is provided with a toothed structure to prevent the blood vessel from falling off. If the clamping force is too small, the blood flow cannot be effectively blocked, and if the clamping force is too large, it is easy to damage the blood vessel. In addition, the large size of the vascular blocking forceps occupies a certain operative field, which affects the operation. Contents of the invention [0003] The present invention solves the ab...
