Problems solved by technology

In the existing slave-end devices of interventional surgery robots, most of the entire device is exposed to the outside during use; it is easy to transfer bacteria in the main device to the upper catheter holder and guide wire holder
[0011] Even if a hygienic isolation membrane is laid above the main body of the device, due to its irregular structure, especially the position of its large gear, it will cause a large tear at the catheter holder and guide wire holder of the hygienic membrane.
Not conducive to sanitary isolation
[0012] However, in medical operations, the hygienic requirements are almost harsh, and the existing devices are not conducive to the aseptic isolation in the actual operation, and cannot meet the hygienic requirements of the operation.

Abstract

The invention discloses a driven end device of an interventional operation robot and a control method thereof, and belongs to the technical field of a minimally invasive blood vessel interventional operation. The device comprises a main body part, a catheter holder, a guide wire clamper, a torsional assembly and a force measuring assembly, wherein the catheter holder is used for holding a catheter; the guide wire clamper is used for clamping or releasing a guide wire; both the catheter holder and the guide wire clamper can be detachably arranged on the main body part; the catheter holder comprises a medical three-way valve and a clamping assembly; the medical three-way valve is connected with the catheter and is fixed on the main body part through the clamping assembly; the torsional assembly is used for driving a screw cap of the medical three-way valve to drive the catheter to rotate; the force measuring assembly is used for detecting the pushing force of the catheter; the torsionalassembly, the catheter holder and the guide wire clamper are detachably arranged on an upper cover of the main body part. A sanitary isolating membrane can be conveniently added in the operation process; good sanitary conditions are reached; the device is suitable for practical application.

Description

technical field [0001] The invention belongs to the technical field of minimally invasive vascular interventional surgery, and relates to the control technology for catheter guide wires in interventional surgery, and more specifically, to a slave end device of an interventional surgery robot and a control method thereof. Background technique [0002] The increasing incidence of cardiovascular and cerebrovascular diseases has seriously affected national health and social life, and brought enormous pressure to China's medical and health system. Cardiovascular and cerebrovascular diseases have become one of the three major causes of human death. Every year, 16.7 million people die from cardiovascular and cerebrovascular diseases in the world, accounting for 29.2% of all disease mortality. Every year, there are 9 million patients with cardiovascular and cerebrovascular diseases in my country. 2.5 million people died. [0003] Cardiovascular and cerebrovascular minimally invasive...
