Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically to a special-shaped occlusion balloon for proximal anastomosis operation of coronary artery bypass grafting. Background Technique

[0002] When treating patients with coronary heart disease, coronary artery bypass grafting is a conventional treatment method. During this operation, an auxiliary medical device - an occlusion balloon is required. Its main function is to block the patient's artery to provide a good bloodless operation environment for the subsequent anastomosis operation, thereby facilitating the operation. Generally, the usage method is to first make an incision on the surface of the artery, then insert the occlusion balloon into the artery through the incision, and then inject water through the water injection pipe of the balloon to inflate the balloon, thereby blocking the artery.

[0003] When the existing occlusion balloons are in use, most of them are inserted into the artery to be blocked, and the balloon needs to be far away from the anastomosis (suture) position to facilitate anastomosis at the incision. However, in this case, due to the contractility of the artery, most of the incisions will contract. At this time, in order to facilitate suturing, external auxiliary tools are generally required to hold the incision open. In this way, too many surgical instruments will be placed on the operating table, which will undoubtedly interfere with the doctor's operation and thus affect the progress of the operation. Generally speaking, it has certain defects in use. Content of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a special-shaped occlusion balloon for proximal anastomosis operation of coronary artery bypass grafting to solve the problems existing in the above background technique.

[0005] The utility model provides the following technical solutions: A special-shaped occlusion balloon for proximal anastomosis operation of coronary artery bypass grafting, including a catheter. A balloon main body is arranged on the surface of the catheter. The balloon main body includes a sub-balloon and an occlusion balloon. The sub-balloon is fixedly installed on the surface of the catheter, and the occlusion balloon is fixedly included on the surface of the sub-balloon. Water outlet holes are formed on the surface of the catheter, and the water outlet holes are communicated with the sub-balloon. A number of water distribution holes are formed on the surface of the sub-balloon, and the water distribution holes are communicated with the occlusion balloon. The occlusion balloon is circular, the sub-balloon is cylindrical, and the height of the sub-balloon is less than the height of the occlusion balloon and forms a concave part in the middle of the balloon main body. A water injection pipe is connected to the surface of the catheter, and a connector is fixedly installed at the end of the water injection pipe far away from the catheter. The connector is connected to an external syringe, and a valve is installed in the middle of the water injection pipe.

[0006] Further, both the sub-balloon and the occlusion balloon are made of elastic materials, and anti-puncture protective layers are covered on the surfaces of both the sub-balloon and the occlusion balloon.

[0007] Further, the surface of the occlusion balloon in contact with the inner wall of the blood vessel is a cylindrical surface.

[0008] Further, a plurality of circular grooves are provided on the surface of the blocking bladder, and the circular grooves are evenly spaced from each other.

[0009] Further, a pig-tail-shaped protective sleeve is fixedly installed at the end of the catheter away from the water injection pipe, and the protective sleeve is made of a flexible material.

[0010] Further, an indicating balloon is fixedly installed at the end of the catheter close to the water injection pipe.

[0011] The technical effects and advantages of the present utility model:

[0012] 1. In the whole using process of the present utility model, the whole balloon main body is placed under the incision on the artery for blocking, and a concave part is also provided on the surface of the balloon main body. In this way, on the basis of blocking the artery, the balloon main body will simultaneously expand the incision, and the concave part can facilitate the doctor to suture. Thus, the operation can be carried out without the assistance of external instruments to expand the incision, greatly reducing the number of medical instruments on the operating table, and effectively facilitating the doctor's operation.

[0013] 2. In the present utility model, since the blocking bladder on the balloon main body is circular, when the blocking bladder does not fit tightly with the inner wall of the artery inside the artery, the catheter can be directly pulled to tilt the whole blocking bladder, so that the whole artery can be directly blocked, and there is no need to adjust it through a syringe additionally, effectively simplifying the operation and further facilitating the use.

Specific Embodiments

[0018] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The present invention involves a special-shaped blocking balloon for proximal anastomosis of coronary artery bypass grafting and is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0019] Reference Figures 1-3 The utility model provides a special-shaped blocking balloon for proximal anastomosis operation of coronary artery bypass grafting, comprising a catheter 1, a balloon body 2 is arranged on the surface of the catheter 1, the balloon body 2 comprises a sub-balloon 3 and a blocking balloon 4, the sub-balloon 3 is fixedly installed on the surface of the catheter 1, the blocking balloon 4 is fixedly included on the surface of the sub-balloon 3, a water outlet hole 5 is opened on the surface of the catheter 1, and the water outlet hole 5 is communicated with the sub-balloon 3, a plurality of water outlet holes 6 are opened on the surface of the sub-balloon 3, and the water outlet holes 5 are communicated with the sub-balloon 3, the water outlet holes 6 are communicated with the blocking balloon 4, the blocking balloon 4 is annular, the sub-balloon 3 is cylindrical, and the height of the sub-balloon 3 is less than the height of the blocking balloon 4 and a concave portion 9 is formed in the middle of the balloon body 2, a water injection pipe 7 is connected to the surface of the catheter 1, and a connector 8 is fixedly installed at the end of the water injection pipe 7 away from the catheter 1, and the water injection pipe 7 is connected to an external syringe through the connector 8, and a valve 10 is installed in the middle of the water injection pipe 7.

[0020] When in use, first insert the catheter 1 into the artery from the incision and continue to extend it until the balloon body 2 is below the incision. At this time, the syringe filled with water can be connected to the connector 8, and the valve 10 can be opened. Then the water in the syringe is injected into the catheter 1. At this time, the injected water will pass through the water outlet 5 into the air dividing bag 3, and then enter the blocking bag 4 from the water dividing hole 6 to prop up the blocking bag 4. In this way, the blocking bag 4 will block the artery below the incision, and because the blocking bag 4 is below the incision, it will also synchronously open the incision, thereby facilitating the doctor's suture operation. It should be noted that in this process, since the air dividing bag 3 forms a recessed portion 9 in the middle of the balloon body 2, the movement of the needle can be facilitated during the suturing operation, thereby further facilitating the suture operation.

[0021] The dividing airbag 3 and the blocking bag 4 are both made of elastic materials, and the surfaces of the dividing airbag 3 and the blocking bag 4 are covered with an anti-puncture protective layer. In this way, the blocking effect can be ensured while ensuring that the needle will not pierce the balloon body 2 during suturing.

[0022] The surface of the blocking balloon 4 that contacts the inner wall of the blood vessel is a cylindrical surface. In this way, it can ensure the close fit between the blocking balloon 4 and the inner wall of the blood vessel. A number of circular grooves 11 are provided on the surface of the blocking balloon 4, and the circular grooves 11 are evenly spaced from each other. In this way, after the blood enters the circular grooves 11, due to the influence of its own tension, a seal will be formed here, which will play a role in strengthening the blockage.

[0023] A pigtail-shaped protective sleeve 12 is fixedly installed at the end of the catheter 1 away from the water injection pipe 7, and the protective sleeve 12 is made of a flexible material. In this way, it can ensure that the catheter 1 will not scratch the inner wall of the artery when inserted into the artery. An indicating balloon 13 is fixedly installed at the end of the catheter 1 close to the water injection pipe 7. In this way, the inflation state of the balloon main body 2 can be obtained through the indicating balloon 13.

[0024] Therefore, the complete usage process is as follows: First, insert the protective sleeve 12 into the artery from the incision and continue to extend it until the balloon main body 2 is below the incision. At this time, a syringe filled with water can be docked with the connector 8, and the valve 10 is opened. Then, the water inside the syringe is injected into the catheter 1. At this time, the injected water will pass through the water outlet holes 5 and enter the sub-balloon 3, and then enter the inside of the blocking balloon 4 through the water distribution holes 6 to support the blocking balloon 4. In this way, the blocking balloon 4 will block the artery below the incision, and since the blocking balloon 4 is below the incision, it will also synchronously expand the incision, thus facilitating the suture operation of the doctor. It should be noted that during this process, since the sub-balloon 3 forms a concave portion 9 in the middle of the balloon main body 2, during the suture operation, the movement of the needle can be facilitated, and further the suture operation can be facilitated.

[0025] In summary, during the entire usage process, the entire balloon main body 2 is placed below the incision on the artery for blocking, and a concave portion 9 is also provided on the surface of the balloon main body 2. In this way, the balloon main body 2 will expand the incision while blocking the artery, and the concave portion 9 can facilitate the doctor's suture. In this way, the operation can be carried out without the assistance of external instruments to expand the incision, greatly reducing the number of medical devices on the operating table, thus effectively facilitating the doctor's surgical operation.

[0026] At the same time, since the blocking balloon 4 on the balloon main body 2 is circular in shape, when the blocking balloon 4 does not fit tightly with the inner wall of the artery inside the artery, the catheter 1 can be directly pulled to tilt the entire blocking balloon 4. In this way, the entire artery can be directly blocked, so that it is not necessary to adjust it through a syringe additionally, effectively simplifying the operation and further facilitating the use.

[0027] Finally, it should be noted that: in the attached drawings of the disclosed embodiments of the present invention, only the structures related to the disclosed embodiments are involved, and other structures can refer to the general design. Without conflict, the same embodiment and different embodiments of the present invention can be combined with each other;

[0028] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
