Problems solved by technology

[0002] With the development of society and the improvement of people's living standards, people pay more and more attention to their own health. Regular physical examination has become an important method for people to prevent diseases in advance. With the increasing abundance of material resources in recent years, people suffer from The probability of cerebrovascular diseases is also greatly increased. Cerebrovascular diseases lead to stasis on the inner wall of blood vessels, resulting in insufficient blood supply to the brain, which often causes sudden death and poses a huge threat to people's lives. However, when the existing vascular stent is placed, it can only maintain the stability of the stent by a fixed amount of stretching, and it is easy to cause damage to the inner wall of the blood vessel when it is placed, causing people to suffer secondary injuries.

Embodiment 1

[0023] see Figure 1-3 , a carotid artery stent implantation device for ischemic cerebrovascular disease, comprising a fixed sleeve 1, the top of the fixed sleeve 1 is rotatably connected with a stretch adjustment seat 2, and the top of the stretch adjustment seat 2 is slidably connected with a stretch handle 3. A stretch mechanism 4 is provided inside the stretch adjustment seat 2 .

[0024] The stretch mechanism 4 includes a deep hose 41, which is connected to the fixed sleeve 1, and the stretch soft rod 45 provided inside the deep hose 41 is provided with a square hole adapted to the inside of the stretch adjustment seat 2. The square groove of the stretching soft rod 45 is provided at the end far away from the stretching adjustment seat 2 with a circular groove suitable for the in-depth hose. The thickness of the part of the deep blood vessel that the circular groove cooperates with the in-depth soft rod 41 is kept consistent to prevent protrusion In order to cause damage...

Embodiment 2

[0026] see Figure 4-5 , a carotid artery stent implantation device for ischemic cerebrovascular disease, also includes an automatic steering mechanism 5, the automatic steering mechanism 5 includes a steering head 51, and the inside of the steering head 51 is provided with a circular through hole adapted to the floating plate 52 , the interior of the turning head is provided with a rectangular chute adapted to the moving slider 55, one end of the moving slider 55 is provided with a gear tooth adapted to the adjustment wheel 515, and the outer side of the turning head 51 is provided with a gear tooth adapted to the induction frame 56.

Abstract

The invention relates to the technical field of cerebrovascular diseases, and discloses ischemic cerebrovascular disease carotid artery stent implantation equipment, which comprises a fixed sleeve, the top of the fixed sleeve is rotatably connected with a stretching adjusting seat, and the top of the stretching adjusting seat is slidably connected with a stretching handle. According to the ischemic cerebrovascular disease carotid artery stent implantation equipment, an adjusting seat is rotated to drive a stretching soft rod to rotate, the stretching soft rod drives an adjusting sleeve to rotate, the adjusting sleeve moves up and down, a stretching handle is pulled to drive the stretching soft rod to move, the stretching soft rod drives the adjusting sleeve to move, the adjusting sleeve drives a stretching frame to bend, the stretching frame drives a sliding shaft to compress a reset spring, the stretching frame drives an intravascular stent to expand, and then through cooperative use of a deep hose and other mechanisms, the expanding diameter can be freely adjusted according to the width of the blood vessel, a catheter can be deeply inserted to conduct outer side real-time adjusting action, placement and adaptability of the stent are better facilitated, and germs are prevented from being brought in.

Description

technical field [0001] The invention relates to the technical field of cerebrovascular diseases, in particular to a carotid artery stent implantation device for ischemic cerebrovascular diseases.
