DETAILED DESCRIPTION

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] It should be noted that in the description of the present invention, the proximal end and the distal end are relative to the operator of the artificial valve delivery device. The proximal end refers to the end relatively close to the operator, and the distal end refers to the end relatively far from the operator.

[0035] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a delivery device, which is used to deliver an artificial valve, and the delivery device includes an outer tube 100, a sheath tube 200, and an inner tube 300; one end of the sheath tube 200 is connected to one end of the outer tube 100, and the sheath tube 200 is rotatably connected to the outer tube 100, wherein the sheath tube 200 is used to accommodate the artificial valve; the inner tube 300 is arranged in a combined cavity formed by the outer tube 100 and the sheath tube 200, and the inner tube 300 at least partially extends out of the combined cavity; a first operating handle 310, the first operating handle 310 is arranged at one end of the inner tube 300 away from the sheath tube 200; a first hand-held portion 311, the first hand-held portion 311 is arranged on the outer surface of the first operating handle 310, and a holding space is formed between the two; wherein, when the first operating handle 310 is driven to reciprocate along the length direction of the inner tube 300, the inner tube 300 is at least partially extended out of or enters the combined cavity.

[0036] For example, when the user holds the first operating handle 310 during use of the delivery device, the user extends his hand into the holding space to hold the first operating handle 310, so that the inner tube 300 at least partially extends out or enters the combined cavity. This prevents the user from slipping or accidentally falling off the first operating handle 310 due to sweating hands or other reasons during operation of the delivery device, thereby improving the stability and safety of the delivery device during operation.

[0037] Further, such as Figure 2 As shown, the delivery device further includes a second operating handle 110, which is disposed at one end of the outer tube 100 away from the sheath tube 200 and is fixedly connected to the outer tube 100; and a second hand-held portion 111, which is disposed on the outer surface of the second operating handle 110. When the user holds the second operating handle 110 to drive the outer tube 100 to rotate relative to the sheath tube 200, the second hand-held portion 111 limits the position of the user's hand, thereby preventing the user from slipping or accidentally falling off the second operating handle 110 due to sweating of the hands or other reasons during the operation, further improving the stability and safety of the delivery device during the operation.

[0038] Further, such as Figures 3 to 5As shown, a rotating component 400 is provided between the sheath tube 200 and the outer tube 100 for driving the sheath tube 200 to rotate relative to the outer tube 100, and the delivery device further includes a third operating handle 410, which is connected to the rotating component 400; and a third hand-held portion 411, which is provided on the outer surface of the third operating handle 410. The stability and safety of the delivery device during operation are further improved.

[0039] Further, such as Figure 3 As shown, the conveying device also includes a first adsorption member 320 and a second adsorption member 430, the first adsorption member 320 is arranged on the first end surface of the first operating handle 310 close to the third operating handle 410, and the second adsorption member 430 is arranged on the second end surface of the third operating handle 410 close to the first operating handle 310; wherein, when the first end surface and the second end surface abut against each other, a mutually attractive adsorption force is generated between the first adsorption member 320 and the second adsorption member 430, so that the first operating handle 310 and the third operating handle 410 are fitted together, thereby increasing the stability of the conveying device during operation.

[0040] Specifically, either the first adsorption component 320 or the second adsorption component 430 is a first magnetic component, and the other is a metal component that forms a magnetic attraction with the first magnetic component; or, the first adsorption component 320 is a second magnetic component, and the second adsorption component 430 is a third magnetic component, and the two form a first magnetic force that attracts each other.

[0041] Further, such as Figures 3 to 5 As shown, the conveying device further includes a pull rope 420 , which is disposed between the inner tube 300 and the outer tube 100 , and passes through the second operating handle 110 to connect the rotating component 400 and the third operating handle 410 .

[0042] Further, such as Figures 3 to 5 As shown, the delivery device further includes a fixing head 500 , which is disposed inside the sheath tube 200 , and is used for installing an artificial valve.

[0043] Specifically, Figure 5 As shown, the artificial valve is provided with a fixing protrusion, and the fixing head 500 is provided with a fixing groove 510 that cooperates with the fixing protrusion; wherein, the fixing protrusion cooperates with the fixing groove 510 to fix the artificial valve on the fixing head 500 when the artificial valve is received.

[0044] Further, such as Figure 2As shown, the conveying device also includes a guide component 600, which is arranged at one end of the sheath tube 200 away from the outer tube 100; and the guide component 600 is connected to the fixed head 500 through a connecting tube, and the guide component 600 has a streamlined appearance structure; wherein, when the first operating handle 310 is driven to reciprocate along the length direction of the inner tube 300, the inner tube 300 drives the fixed head 500 and the guide component 600 to reciprocate along the length direction of the inner tube 300.

[0045] On the other hand, Figure 6 As shown, the utility model also provides a surgical device, which includes a conveying device and a disinfection box 700 as in any of the above technical solutions. The disinfection box 700 is provided with a placement space for placing the conveying device. The disinfection box 700 is used to sterilize and disinfect the conveying device to avoid contamination of the conveying device when not in use.

[0046] When in use, the user controls the first operating handle 310 to move distally, so that the fixing head 500 and the guide component 600 move distally, and when the fixing head 500 is exposed from the sheath 200, the fixing protrusion of the artificial valve is fixed in the fixing groove 510. After the artificial valve is fixed, the first operating handle 310 is controlled to move proximally, so that the fixing head 500 and the artificial valve are pulled into the sheath 200, and the guide component 600 seals the sheath 200. When in use, the user controls the first operating handle 310 through the first hand-held part 311, which avoids the first operating handle 310 from falling off during operation, and improves the stability of the delivery device during operation.

[0047] Furthermore, the guide component 600 is controlled to probe into the puncture port, and the sheath 200 containing the artificial valve is brought into the human body. The guide component 600 enters the heart along the blood vessels of the femoral vein, and the sheath 200 is transported to the diseased valve. After the outer tube 100 is fixed, the second operating handle 110 is controlled by the second hand-held part 111 to pull the pull rope 420, so that the rotating part 400 drives the sheath 200 to rotate relative to the outer tube 100. When the sheath 200 rotates, it drives the fixing head 500, the artificial valve and the guide component 600 to rotate together to adjust the position of the artificial valve.

[0048] After the positions of the sheath 200, the fixing head 500 and the artificial valve are determined, the first operating handle 310 is controlled to move distally through the first hand-held portion 311, so that the guide component 600 moves distally. After the artificial valve in the sheath 200 is released, the first operating handle 310 is controlled to move proximally through the first hand-held portion 311, so that the guide component 600 moves proximally, and the fixing head 500 is pulled back into the sheath 200. At the same time, the guide component 600 is pulled back to seal the sheath 200.

[0049] Finally, the first hand-held portion 311 and the third hand-held portion 411 are used to simultaneously control the first operating handle 310 and the third operating handle 410 to move toward the proximal end, so as to remove the delivery device from the human body.

[0050] Although the utility model is disclosed as above, the utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the scope defined by the claims.
