Problems solved by technology

[0003] However, the integrated branch stent has the following problems during use: the branches of the stent are positioned in the branch vessels, and after the release of the main body of the stent is completed, when the delivery device is retracted, the delivery device is likely to cause disturbance to the stent, causing the stent to shift, and in severe cases It may even cause the stent branch to protrude from the branch vessel, so that the branch blood flow is blocked

Abstract

The invention relates to a support device and a support system, the support device comprises a support and a holding mechanism, the support comprises a main support and a branch support arranged on the main support, and a connecting part is arranged on the branch support; the holding mechanism comprises a traction part, the near end of the traction part is used for being connected with the connecting part, and the far end of the traction part is used for being connected with an external positioning mechanism; the traction part is configured to apply pulling force to the connecting part under the action of the external positioning mechanism so that the stent can be kept at the preset position, and displacement of the stent caused by influence in the surgical operation and the withdrawing process of the conveying device is avoided.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a bracket device and a bracket system. Background technique [0002] The one-piece branch stent can effectively isolate the hemangioma cavity when applied to the lesion involving the branch vessels of the aortic arch, and at the same time avoid the endoleak problem at the branch vessels. Blood flow blocking effect. [0003] However, the integrated branch stent has the following problems during use: the branches of the stent are positioned in the branch vessels, and after the release of the main body of the stent is completed, when the delivery device is retracted, the delivery device is likely to cause disturbance to the stent, causing the stent to shift, and in severe cases It may even cause the stent branch to protrude from the branch blood vessel, so that the branch blood flow is blocked. Contents of the invention [0004] The purpose of the present invention i...
