Embodiment 1

[0056] Please refer to Figure 1-Figure 3 ,in, figure 1 It is a schematic cross-sectional view of the delivery carousel for surgery according to Embodiment 1 of the present invention; figure 2 It is a schematic front view of the limiting part of Embodiment 1 of the present invention; image 3 It is a schematic front view of the rotating part of Embodiment 1 of the present invention.

[0057] Such as figure 1 As shown, the present embodiment provides a delivery carousel for surgery, which is used to store, coil and deliver a long catheter 50 or guide wire 60 . The delivery carousel includes a rotating part 02, and a guide groove 021 matching the diameter of the catheter 50 or the guide wire 60 is provided along at least a part of the outer circumference of the rotating part 02, and the guide groove 021 is used for storing The catheter 50 or the guide wire 60 is coiled. The rotating part 02 is used to deliver the catheter 50 or the guide wire 60 through forward and reverse...

Embodiment 2

[0094] Please refer to Figure 7 , which is a schematic cross-sectional view of the delivery device for surgery according to the second embodiment of the present invention.

[0095] The difference from Embodiment 1 is that in this embodiment, the second conveying carousel 20 is directly arranged on the first rotating part 12 . Specifically, in this embodiment, the first rotating part 12 of the first conveying carousel 10 has a certain structural strength, and the second limiting part 21 is arranged on one side of the first rotating part 12 provided with the first fixing part 122. side and directly connected with the first rotating part 12. Such a structure can also realize that the rotation of the first delivery carousel 10 synchronously drives the second delivery carousel 20 to rotate, and then can drive the catheter 50 and the guide wire 60 to advance and retreat synchronously. Therefore, the connection part 23 in the first embodiment is eliminated, which can make the stru...

Embodiment 3

[0098] Please refer to Figure 8 , which is a schematic partial cross-sectional view of the delivery carousel for surgery according to the third embodiment of the present invention.

[0099] The difference from Embodiment 1 is that in this embodiment, the first rotating part 12 has a raised outer peripheral part, the first guide groove 121 is arranged in the raised outer peripheral part, and the first limiting part 11 is an ordinary The disc has no flange, and its first limiting wall 111 is the outer peripheral wall of the disc. The inner diameter of the turned outer peripheral part of the first rotating part 12 is slightly larger than the outer diameter of the first limiting part 11. Moreover, the first limiting portion 11 is concentrically arranged with the first rotating portion 12 , so that the first limiting portion 11 is actually sleeved inside the first rotating portion 12 . Likewise, the first guide groove 121 matches the outer contour of the conduit 50 , and the cond...

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...
