Embodiment 1

[0056] Such as Figure 1 to Figure 7 The surgical implantation device of the medical blood vessel dilator shown includes a shaft 1 and a plurality of sleeves 2 sleeved outside the shaft. The end face is provided with at least one control rod 5 along the axial direction of the shaft sleeve, which can be set as two or one. The two control rods can facilitate the control of the rotation of the sleeve, but the installation is cumbersome. Rod 5 is made as one; Control rod 5 is provided with detachable rotating strut 6, and described cover disc 2 is provided with retaining ring 3 on the same side, and blood vessel dilator 8 is installed in retaining ring 3, and retaining ring 3 The outer diameter of the ring is the same as that of the sleeve 2, the thinner the wall thickness of the retaining ring 3, the better, as long as its strength can be satisfied, the material of the retaining ring 3 can be stainless steel, and the sleeve 2 includes an inner disc 21 and The outer disc 22 insta...

Embodiment 2

[0069] Such as Figure 7 to Figure 14 The new surgical implantation device of the medical vascular dilator shown includes a shaft 1 and a number of sleeves 2 sleeved outside the shaft. The control end of the shaft 1 is covered with a sleeve 4, and the sleeve 4 is close to the sleeve. The end face of the shaft sleeve is provided with at least one control rod 5 along the axial direction of the shaft sleeve, and the control rod 5 is provided with a detachable rotating strut 6, and the same side of the sleeve 2 is provided with a stop ring 3, and Outer diameter is identical with the outer diameter of cover disc 2, and described cover disc 2 comprises inner disc 21 and the outer disc 22 that is installed on the outer periphery of inner disc; It is convenient to control the rotation of the sleeve, but the installation is cumbersome. In this embodiment, the control rod 5 is set as one. The thinner the wall thickness of the retaining ring 3, the better. As long as its strength can mee...

Abstract

The invention discloses a medical surgery implant device of a vessel dilator. The device comprises a shaft rod and a plurality of sleeve plates, wherein the shaft rod is sleeved with the sleeve plates, an operation end of the shaft rod is sleeved with a shaft sleeve, the end face, close to the sleeve plates, of the shaft sleeve is provided with at least one control rod along an axial direction ofthe shaft sleeve, the control rod is provided with a detachable rotation supporting rod, same side faces of the sleeve plates are provided with baffle rings, the outer diameters of the baffle rings are the same as those of the sleeve plates, and each sleeve plate comprises an inner plate and an outer plate arranged on the periphery of the corresponding inner plate. The invention aims for providingthe medical surgery implant device of the vessel dilator capable of being operated in surgeries and an operation method thereof.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a surgical implantation device of a medical blood vessel dilator and an operation method thereof. Background technique [0002] A vasodilator is a medical device used to dilate blood vessels so that blood can flow smoothly. Chinese patent 2010202319042 discloses a kind of cardiovascular expansion device, the mesh stent is installed in a guide tube in advance, and a stylet is also installed in the guide tube at the same time, the guide tube is implanted into the blood vessel first during the operation, and then used The die pushes the mesh support out. Although this "cardiovascular expansion device" can simplify the operation to a certain extent and improve the accuracy of the mesh stent in place, its application range is limited because the diameter of the guide tube is larger than that of the mesh stent, and it makes installation difficult. bigger. Contents of the invention ...
