Vascular interventional instrument twisting device and method

Abstract

The invention relates to the technical field of surgical robots, and provides a blood vessel interventional instrument twisting device and method. The blood vessel interventional instrument twisting device comprises a supporting table on which two parallel first guide rails are arranged; a driving wire feeding mechanism which comprises a first support assembly, a driving conveying belt and a driving carrier roller belt wheel, the first support assembly being arranged on the first guide rail in a sliding mode, and the driving conveying belt being matched with the driving carrier roller belt wheel in a tensioning mode; a pressing mechanism which comprises a second support assembly, an adjusting assembly and a pressing plate; a driven wire feeding mechanism which comprises a driven conveying belt and a driven carrier roller belt wheel. The gap between the driven conveying belt and the driving conveying belt is adjusted through an adjusting assembly to adjust the clamping force on a guide wire, so that the slipping phenomenon in the twisting process is prevented, relative movement between the driving conveying belt and the driven conveying belt is guaranteed, effective twisting force is generated on the guide wire, and the twisting efficiency, the operation efficiency and the safety are improved.

Description

technical field [0001] The invention relates to the technical field of surgical robots, in particular to a twisting device and method for vascular interventional instruments. Background technique [0002] At present, the number of cardiovascular diseases continues to increase, leading to increased medical burdens, and has gradually become the number one disease that threatens the lives and health of the people. At present, the mainstream way to treat such cardiovascular and cerebrovascular diseases is interventional therapy, that is, firstly, the radial artery or femoral artery is punctured, and then the interventional device is delivered to the lesion area through the human blood vessel, so as to achieve the purpose of dilating narrowed blood vessels and embolizing malformed blood vessels. Interventional surgery needs to be guided by the digital subtraction angiography (DSA) system, so that the operator needs to wear heavy protective clothing and be exposed to the radiation...
