Description

Technical Field

[0001] The utility model relates to the technical field of aortic valve implantation surgical instruments, in particular to a conveying device for transcatheter aortic valve implantation surgery with a valve positioning function. Background Art

[0002] With the continuous development of medical technology, interventional cardiac surgery technology is also constantly innovating. Transcatheter aortic valve implantation has become a relatively common alternative to traditional open surgery. In order to further improve the accuracy and safety of the operation, it is necessary to continuously improve surgical equipment and tools, including delivery devices.

[0003] Traditional surgical delivery devices cannot provide sufficient precision, so a new delivery device with valve positioning function is needed.

[0004] A delivery device for transcatheter aortic valve implantation surgery with a valve positioning function is now proposed. Utility Model Content

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A delivery device for transcatheter aortic valve implantation surgery with valve positioning function comprises a driving mechanism, one end of the driving mechanism is movably connected to the delivery mechanism, the delivery mechanism clamps and installs a catheter, a sleeve is sleeved on a part of the outer surface of the catheter, a camera is arranged at the right end of the catheter, the driving mechanism comprises a delivery motor; the delivery mechanism comprises a sleeve clamp.

[0007] A further improvement of the technical solution of the utility model is that the sleeve and the conveying motor of the driving mechanism are fixed on the operating table when in use.

[0008] A further improvement of the technical solution of the utility model is that a conveying disc is driven and installed on one end of the conveying motor, and a fixing screw is fixedly inserted on one end of the conveying disc.

[0009] A further improvement of the technical solution of the utility model is that the conveying plate is rotatably mounted with a conveying rod through a fixed screw rod.

[0010] A further improvement of the technical solution of the utility model is that a connecting screw is inserted through one end of the conveying rod, and one end of the connecting screw is threadedly fixed and inserted on one side of the conveying mechanism.

[0011] A further improvement of the technical solution of the utility model is that the driving mechanism is rotatably connected to the conveying mechanism through a connecting screw.

[0012] A further improvement of the technical solution of the utility model is that: clamping plates are fixedly installed at both ends of the sleeve clamp, an electric push rod is installed on the clamping plate, and a connecting shaft is fixedly installed on one side of the clamping plate.

[0013] A further improvement of the technical solution of the utility model is that the conveying mechanism is connected to the driving mechanism via a connecting shaft, and one end of the electric push rod penetrates through the sleeve clamp and the clamping plate and contacts the two sides of the catheter.

[0014] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0015] 1. The utility model provides a delivery device for transcatheter aortic valve implantation surgery with a valve positioning function. A camera is provided at the right end of the catheter to provide image guidance. During the operation, the camera uses real-time imaging technology to help the surgeon accurately guide the device to the correct position and ensure the correct implantation of the artificial valve, ensuring that the artificial valve can be accurately positioned at the patient's aortic orifice during the implantation process. When in use, the sleeve and the delivery motor are fixed on the operating table for catheter delivery.

[0016] 2. The utility model provides a delivery device for transcatheter aortic valve implantation surgery with a valve positioning function. The delivery disc is installed with a delivery rod by rotating a fixed screw. The fixed screw deviates from the center point of the delivery disc. The delivery motor drives the delivery disc to rotate, and after the rotation, the delivery rod is driven to reciprocate laterally. The driving mechanism is connected to the delivery mechanism by rotating the connecting screw, thereby driving the delivery mechanism to reciprocate on the outer surface of the catheter, cooperating with the delivery mechanism to clamp and release the catheter, thereby continuously pushing the catheter to move, so that the catheter can be delivered in or continuously pulled out.

[0017] 3. The utility model provides a delivery device for transcatheter aortic valve implantation surgery with a valve positioning function. The driving mechanism rotates the connected delivery mechanism through a connecting screw, thereby driving the delivery mechanism to reciprocate on the outer surface of the catheter, and one end of the electric push rod penetrates the sleeve clamp and the clamp plate and contacts the two sides of the catheter. When the sleeve clamp moves to the right, the electric push rods on both sides of the catheter clamp the two sides of the catheter, thereby pushing the catheter to one side for delivery. When the sleeve clamp moves to the right after the maximum distance and starts to move back, the electric push rod cancels the clamping of the two sides of the catheter, so that the sleeve clamp will not drive the catheter when it is reset. This step is repeated to continuously deliver the catheter. The sleeve plays a positioning and guiding role to ensure the correct position and good function of the valve. By providing a delivery device with a valve positioning function, errors and risks during the operation can be reduced, and the incidence of complications can be reduced.

[0024] The present invention is further described in detail below in conjunction with the embodiments:

[0025] like Figure 1-2 As shown, the utility model provides a delivery device for transcatheter aortic valve implantation surgery with a valve positioning function, including a driving mechanism 1, one end of the driving mechanism 1 is movably connected to a delivery mechanism 2, the delivery mechanism 2 clamps and installs a catheter 4, a sleeve 3 is partially sleeved on the outer surface of the catheter 4, a camera 5 is arranged at the right end of the catheter 4, and the sleeve 3 and the delivery motor 11 of the driving mechanism 1 are fixed on the operating table when in use.

[0026] In this embodiment, a camera 5 is provided at the right end of the catheter 4 to provide image guidance. During the operation, the camera 5 uses real-time imaging technology to help the surgeon accurately guide the device to the correct position and ensure the correct implantation of the artificial valve, ensuring that the artificial valve can be accurately positioned at the patient's aortic orifice during the implantation process. When in use, the sleeve 3 and the delivery motor 11 are fixed on the operating table to carry out catheter 4 delivery.

[0027] like Figure 3-4 As shown, the utility model provides a technical solution: preferably, the driving mechanism 1 includes a conveying motor 11, one end of the conveying motor 11 is driven to install a conveying disc 12, one end of the conveying disc 12 is fixedly plugged with a fixing screw 14, the conveying disc 12 is rotatably installed with a conveying rod 13 through the fixing screw 14, one end of the conveying rod 13 is penetrated and plugged with a connecting screw 15, one end of the connecting screw 15 is threadedly fixed and plugged on one side of the conveying mechanism 2, and the driving mechanism 1 is rotatably connected to the conveying mechanism 2 through the connecting screw 15.

[0028] In this embodiment, the conveying disc 12 is rotatably installed with the conveying rod 13 through the fixed screw 14, and the fixed screw 14 deviates from the center point of the conveying disc 12. The conveying motor 11 drives the conveying disc 12 to rotate, and after the rotation, it drives the conveying rod 13 to reciprocate horizontally, and the driving mechanism 1 is connected to the conveying mechanism 2 by rotating the connecting screw 15, thereby driving the conveying mechanism 2 to reciprocate on the outer surface of the catheter 4, cooperating with the conveying mechanism 2 to clamp and release the catheter 4, thereby continuously pushing the catheter 4 to move, so that the catheter 4 can be transported in or continuously pulled out.

[0029] like Figure 5 As shown, the utility model provides a technical solution: preferably, the conveying mechanism 2 includes a sleeve clamp 21, and clamps 22 are fixedly installed at both ends of the sleeve clamp 21, and an electric push rod 23 is installed on the clamp 22. A connecting shaft 24 is fixedly installed on one side of the clamp 22. The conveying mechanism 2 is connected to the driving mechanism 1 through the connecting shaft 24, and one end of the electric push rod 23 penetrates the sleeve clamp 21 and the clamp 22 and then contacts both sides of the catheter 4.

[0030] In this embodiment, the driving mechanism 1 is connected to the conveying mechanism 2 by rotating through the connecting screw 15, thereby driving the conveying mechanism 2 to reciprocate on the outer surface of the catheter 4, and one end of the electric push rod 23 penetrates the sleeve clamp 21 and the clamp plate 22 and contacts the two sides of the catheter 4. When the sleeve clamp 21 moves to the right, the electric push rods 23 on both sides of the catheter 4 clamp the two sides of the catheter 4, thereby pushing the catheter 4 to one side for conveying. When the sleeve clamp 21 moves to the right after the maximum distance and starts to move back, the electric push rod 23 cancels the clamping of the two sides of the catheter 4, so that the sleeve clamp 21 will not drive the catheter 4 when it is reset. Repeat this step to continuously convey the catheter 4. The sleeve 3 plays a positioning and guiding role to ensure the correct position and good function of the valve. By providing a conveying device with a valve positioning function, errors and risks during surgery can be reduced, and the incidence of complications can be reduced.

[0031] The working principle of the delivery device for transcatheter aortic valve implantation surgery with valve positioning function will be described in detail below.

[0032] like Figure 1-5As shown, a camera 5 is provided at the right end of the catheter 4 to provide image guidance. During the operation, the camera 5 uses real-time image technology to help the surgeon accurately guide the device to the correct position and ensure the correct implantation of the artificial valve, and ensure that the artificial valve can be accurately positioned at the patient's aortic orifice during the implantation process. When in use, the sleeve 3 and the delivery motor 11 are fixed on the operating table to deliver the catheter 4. The delivery disc 12 is rotated to install the delivery rod 13 through the fixed screw 14. The fixed screw 14 deviates from the center point of the delivery disc 12. The delivery motor 11 drives the delivery disc 12 to rotate, and after the rotation, it drives the delivery rod 13 to reciprocate horizontally. The driving mechanism 1 is connected to the delivery mechanism 2 by rotating the connecting screw 15, thereby driving the delivery mechanism 2 to reciprocate on the outer surface of the catheter 4, and cooperates with the delivery mechanism 2 to clamp and release the catheter 4, thereby continuously pushing the catheter 4 to move, so that The catheter 4 can be delivered in or continuously pulled out. The driving mechanism 1 is connected to the delivery mechanism 2 by rotating through the connecting screw 15, thereby driving the delivery mechanism 2 to reciprocate on the outer surface of the catheter 4, and one end of the electric push rod 23 penetrates the sleeve clamp 21 and the clamp plate 22 and contacts the two sides of the catheter 4. When the sleeve clamp 21 moves to the right, the electric push rods 23 on both sides of the catheter 4 clamp the two sides of the catheter 4, thereby pushing the catheter 4 to one side for delivery. When the sleeve clamp 21 moves to the right after the maximum distance and starts to move back, the electric push rod 23 cancels the clamping of the two sides of the catheter 4, so that the sleeve clamp 21 will not drive the catheter 4 when it is reset. Repeat this step to continuously deliver the catheter 4. The sleeve 3 plays a positioning and guiding role to ensure the correct position and good function of the valve. By providing a delivery device with a valve positioning function, errors and risks during surgery can be reduced, and the incidence of complications can be reduced.

[0033] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
