For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following is an explanation of the embodiments of the present utility model based on the overall structure of the present utility model.

[0028] Three components are packaged as a set and can be sterilized:

[0029] ① The blocking device is made of lightweight hard materials such as plastic, is not easy to puncture the blood vessel 10, is easy to disinfect and sterilize, and is disposable; the internal main pipeline 2 is white and the auxiliary pipeline 3 is blue for easy identification.

[0030] ② Cotton rope 9, used as a component for ligating blood vessels 10;

[0031] ③ A guide wire with a hook (not shown in the figure, this is a common tool in the field of medical devices), which serves as a component for guiding threading.

[0032] See also Figure 1-Figure 5 As shown in the figure, after the cotton rope 9 is circumferentially wrapped around the blood vessel 10, the two ends of the cotton rope 9 pass through the common pipe 6, the main pipe 2, and the auxiliary pipe 3 in the blocking device, and are tightened at the top of the blocking device. By tightening the two ends of the cotton rope 9, the blood circulation is blocked.

[0033] There are three embodiments as follows:

[0034] like Figure 1-Figure 5 As shown, embodiment 1: a pulmonary artery blocking device for thoracoscopic surgery, including a device body 1, the device body 1 is provided with a main pipeline 2, a secondary pipeline 3 and a common pipeline 6, the opening positions of the main pipeline 2 and the secondary pipeline 3 are located at the top end of the device body 1, the opening position of the common pipeline 6 is located at the bottom end of the device body 1, and the bottoms of the main pipeline 2 and the secondary pipeline 3 are connected to the common pipeline 6; a shearing portion 7 is opened on the side of the device body 1, and the shearing portion 7 is connected to the main pipeline 2 or the secondary pipeline 3.

[0035] The shearing portion 7 is an arc-shaped notch structure, which is recessed into the inside of the device body 1 and connected to the main pipe 2 or the auxiliary pipe 3. Firstly, it is convenient to check whether the cotton rope 9 is completely tightened. Secondly, when the cotton rope 9 is released from the tightened state, it is convenient to cut it at the shearing portion 7 with a scalpel, so as to prevent the blood vessel 10 from being easily damaged by cutting it with a scalpel at the bottom of the device body 1, or to avoid the situation where the cotton rope 9 is tightened at the top of the device body 1 and there is no suitable cutting position, which makes it difficult to cut the cotton rope 9.

[0036] The device body 1 is a truncated cone with a top diameter larger than a bottom diameter. When in use, the device body 1 is placed in the chest cavity, and the contact area between the bottom surface of the device body 1 and the chest cavity is smaller. When the cotton rope 9 is knotted on the top surface of the device body 1, the knotted point can be completely placed on the top of the device body 1.

[0037] A first gasket 4 is pasted on the top of the device body 1, and a through hole corresponding to the main pipeline 2 and the auxiliary pipeline 3 is provided on the first gasket 4. A second gasket 5 is pasted on the bottom of the device body 1, and a through hole corresponding to the common pipeline 6 is provided on the second gasket 5. The sizes of the first gasket 4 and the second gasket 5 are adapted to the end of the device body 1. The outer sides of the first gasket 4 and the second gasket 5 and the inner sides of the through hole are smoothly transitioned. The first gasket 4 and the second gasket 5 are made of silicone material. The flexible material of the second gasket 5 protects the chest cavity and the tied blood vessels 10 from damage. The flexible material of the first gasket 4 provides a buffer for the tied cotton rope 9 to avoid being tied too tightly and damaging the blood vessels 10. The device body 1 is a plastic part with a lightweight material to avoid excessive weight.

[0038] Working principle: as attached Figure 3 As shown, it includes: a cotton rope 9 for blocking a blood vessel 10; a guide wire with a hook (not shown, a common tool in the medical field), which can easily hook out the cotton rope 9. The blocking device is the main accessory, and the whole is made of lightweight hard materials such as plastic.

[0039] When the pulmonary artery needs to be blocked during surgery, the pulmonary artery is fully freed. First, a cotton rope 9 is tied around the side of the blood vessel 10 several times, and then a hooked guide wire is passed through the main pipeline 2 or the auxiliary pipeline 3 of the blocking device, and the two ends of the tied cotton rope 9 are hooked out from the main pipeline 2 and the auxiliary pipeline 3 respectively. Then, a double-jointed instrument is used to place the blocking device next to the pulmonary artery in the chest cavity, and a knotter is used to tie and tighten the cotton rope 9. The knot is located on the side of the main pipeline 2. The cotton rope 9 can be fixed and provide space for disconnection. At this time, the blood flow of the pulmonary artery is blocked, and subsequent surgical operations can be performed. After the surgical operation is completed, it is necessary to release the blocking device and restore the blood flow of the pulmonary artery. At this time, laparoscopic scissors are used to cut the cotton rope 9 at the shearing part 7 on the side of the main pipeline 2 or the auxiliary pipeline 3, remove the cotton rope 9, release and remove the blocking device, and restore blood flow. The cut device can be easily removed using a double-jointed instrument.

[0040] like Figure 6-Figure 7 As shown, in the second embodiment, the shearing part 7 can also be the separation part 1-1 of the device, and the device body 1 includes the main body 1-2 and the separation part 1-1, and the main body 1-2 and the separation part 1-1 are combined to form the main pipeline 2 and the common pipeline 6, or to form the secondary pipeline 3 and the common pipeline 6. After the operation is completed, it is necessary to release the blocking device, restore the pulmonary artery blood flow, and separate the separation part 1-1 of the device. At this time, the cotton rope 9 can be cut with laparoscopic scissors, and the cotton rope 9 can be taken out, and the blocking device can be released and taken out to restore the blood flow. The cut device can be easily taken out using a double-joint instrument.

[0041] The main body 1-2 and the separation part 1-1 are connected by magnetic attraction or snap-on connection. After the operation, the internal cotton rope 9 can be directly cut by disassembling the separation part 1-1, and the first gasket 4 and the second gasket 5 are divided according to the shape of the top and bottom of the main body 1-2 and the separation part 1-1, and are placed on the main body 1-2 and the separation part 1-1 respectively.

[0042] like Figure 8-Figure 9 As shown, in the third embodiment, the shearing portion 7 can also be a shearing groove 8, which is arranged to be inclined downward and connected to the main pipeline 2 or the auxiliary pipeline 3. The setting position and direction of the shearing groove 8 facilitate the insertion of scissors and the shearing operation. After the surgical operation is completed, it is necessary to release the blocking device to restore the blood flow of the pulmonary artery. At this time, the laparoscopic scissors are used to cut the cotton rope 9 at the position of the shearing groove 8 on the side of the main pipeline 2 or the auxiliary pipeline 3, remove the cotton rope 9, release and remove the blocking device, and restore the blood flow. The sheared device can be easily removed using a double-joint instrument.

[0043] This device is designed as a set and sterilized, so that doctors can use it at any time, which improves the efficiency of the operation. The device is simple and effective in design, and can safely block blood flow, providing protection for the operation. During the suturing process, the blocking device can be placed in the chest cavity as a whole to avoid passing through the incision, reduce problems such as winding and instrument interference, simplify the operation process, and ensure the safety of the operation. After the anastomosis is completed, the main pipeline 2 and the auxiliary pipeline 3 are set in the main body 1 of the device, and the cotton rope 9 is directly and quickly cut at the position of the shearing part 7, and the blocking device is safely, quickly and simply removed to avoid entanglement and problems with the anastomosis, thereby improving the success rate of the operation.

[0044] The device has a simple structure and is easy to operate. It reduces interference and risks and improves surgical efficiency. It will provide more effective tools and technical support for minimally invasive surgery, and is expected to improve difficulties during the operation and enhance the safety and success rate of the operation. After the blocking device is placed in the chest cavity, it will not cause the cotton rope 9 to be entangled with the instrument, or the instruments to interfere with each other, thereby improving the efficiency of the operation.

[0045] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is limited by the appended claims rather than the above description. Therefore, it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the present invention, and any figure marks in the claims should not be regarded as limiting the claims involved.
