Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0014] see figure 1 The structural diagram of the surgical anastomosis auxiliary magnetic ring includes a magnetic ring cylinder 1, the magnetic ring cylinder 1 is cylindrical, and is used in pairs during surgery. On the outer circumference of the magnetic ring cylinder 1, there are several open grooves 2 along the axial direction, and the several open grooves 2 are connected and communicated with several circular through holes 3 arranged on the wall of the magnetic ring cylinder. ; On the end face of the magnetic ring cylinder 1, there are two symmetrical removal slots 4 along the axial direction on the cylinder wall along the diameter direction. The dismantling seam 4 divides the magnetic ring cylinder body 1 into two halves, which are magnetically anastomosed during use, and the magnetic ring is separated and taken out after the operation is completed.

Abstract

A magnetic ring for helping the surgical anastomose features that a pair of cylindrical magnetic rings is needed for surgical operation, and said magnetic ring has serveral open axial slots on its external circumference surface and symmetrical axial seams for dividing it into two halves. When surgical operation is performed, said two halves are magnetically connected. When the operation is finished, they can be taken away.

Description

technical field [0001] The invention relates to a surgical medical instrument, in particular to a surgical anastomosis auxiliary magnetic ring which can be used for blood vessel anastomosis or biliary tract operation. Background technique [0002] The traditional method of manual suturing of blood vessels is to use a blood vessel clip to clamp the two broken ends of blood vessels, and perform short anastomosis after closing them together. Small blood vessels need to be operated under a microscope. Although it has the advantages of being meticulous and reliable, it is not easy to guarantee the needle distance and spacing. The soft blood vessels move back and forth during the anastomosis, making it difficult to insert and exit the needle, and the anastomotic thread is easy to knot. The front and rear walls are sewn together, so it is difficult to grasp, and it is difficult to popularize in the field of surgery, especially in the field of organ transplantation. [0003] The co...
