Conveying rotary disc for operation, conveying device, and method for storing and delivering catheter guide wire

Abstract

The invention provides a conveying rotary disc for an operation, a conveying device and a method for storing and delivering catheter guide wire. The conveying rotary disc comprises a rotary part provided with a guide groove in the circumferential direction, a catheters or a guide wire are wound and stored on the rotary part, a storage size of the catheter and the guide wire is saved, the size of awhole surgical robot is reduced, and the structure of the surgical robot is simplified. The rotating part is used for conveying the catheter or the guide wire wound on the rotary part through forwardand reverse rotation, the problem that in the prior art, when friction wheels are adopted for pushing and encounter resistance, the friction wheels are prone to slipping and losing steps is solved, and therefore advancing and retreating conveying control precision of the catheter and the guide wire can be improved, and control difficulty is lowered. The catheter or guide wire coiled and stored onthe conveying rotary disc are basically in a closed state and are not directly exposed, so that the reliability of sterile operation is greatly improved. In the conveying device, a second conveying rotary disc is preferably arranged on a first conveying rotary disc, advancing and retreating conveying of the catheter or the guide wire can be controlled respectively, and synchronous advancing and retreating conveying of the catheter and the guide wire can also be controlled.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to a delivery carousel for surgery, a delivery device and a storage and delivery method for catheter guide wires. Background technique

[0002] In recent years, endovascular interventional technology has become one of the main means of treating cardiovascular and cerebrovascular diseases because of its minimal invasiveness and good therapeutic effect. The core technology of endovascular interventional technology is that under the guidance of CT and other images, the guide wire and catheter cooperate to exchange and transport the diagnostic and therapeutic interventional equipment to the target position. Catheters and guidewires can be delivered manually or by surgical robots or a combination of manual and mechanical. The manual delivery method needs to rely on the operator's personal experience, which is prone to misoperation and takes a long time. Surgical robots can effe...
