Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an aortic puncture and perforation device. Background Technology

[0002] Aortic punchers are used in coronary artery bypass grafting surgery in cardiac surgery to create circular openings in the aortic wall, i.e., to create an anastomosis on the aortic side of the graft. The punching effect of the aortic puncher directly affects the success of the graft anastomosis, and thus the overall surgical outcome.

[0003] Currently, when performing aortic puncture and perforation, it is usually necessary to first use tissue scissors to remove the adventitia of the aortic wall, then use a blade to cut open the aortic wall at the pre-perforation site, and then use an aortic punch to vertically insert the end of the aortic punch into the aortic wall incision. By holding the handle and pushing the piston of the punch, the sleeve of the punch is driven through the end, thereby forming a regular, circular hole.

[0004] The applicant has found that the prior art has at least the following technical problems: the aortic puncture and perforation process is relatively complicated, the operation is relatively inconvenient, and it will also increase the operation time. Utility Model Content

[0005] The purpose of this invention is to provide an aortic puncture and perforation device to solve the technical problems existing in the prior art. The preferred technical solutions among the various technical solutions provided by this invention and their numerous technical effects are detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An aortic puncture and perforation device includes a sharp blade and an end cap. The sharp blade includes a blade body and a cutting section. The blade body is a sheet-like structure with a uniform thickness. The front end of the blade body forms a blade tip, and a cutting section is provided on each side of the blade body. The rear end of the blade body is connected to the front end of the end cap, and the width of the rear end of the blade body is the same as the diameter of the end cap.

[0008] Preferably, the cutting part is a blade capable of cutting the aortic wall.

[0009] Preferably, the two cutting portions are arranged symmetrically.

[0010] Preferably, the planar shape of the blade body is an isosceles triangle.

[0011] Preferably, the rear end of the blade body is fixedly connected to the front end of the tip.

[0012] Preferably, it further includes a connecting rod, a handle, a sleeve, a piston, and an elastic element. The front end of the connecting rod is connected to the rear end of the end head. The connecting rod is connected to the handle. The sleeve is located between the connecting rod and the handle. The sleeve is rotatably connected to the handle and connected to the piston. The piston is slidably connected to the handle. The elastic element is connected to both the handle and the piston.

[0013] Preferably, the elastic element is a spring.

[0014] Preferably, the handle has two symmetrically arranged handle portions for gripping.

[0015] The beneficial effects of this utility model are as follows: When using the aortic puncture and perforation device, it can directly puncture the aortic wall perpendicularly at the predetermined puncture position. First, the tip of the blade is inserted into the aortic wall, and then it is pushed forward. The cutting parts on both sides can cut the aortic wall, further enlarging the incision. The incision shape is straight. Furthermore, since the width of the rear end of the blade body is the same as the diameter of the tip, after the blade is fully inserted into the aortic wall, the tip can also be inserted into the aorta relatively smoothly.

[0016] When using the aortic puncture and punching device, by attaching a sharp blade to the front end of the tip, the steps of cutting the aortic wall adventitia and cutting the aortic wall can be eliminated. The entire process only requires the aortic puncture and punching device, and the aortic puncture can be completed in one go, which is more convenient and optimizes the operation process, effectively saving surgical time.

[0030] Reference Figures 1 to 2 The present invention provides an aortic puncture and punching device, including a sharp blade 1 and an end 2. The sharp blade 1 includes a sharp blade body 11 and a cutting part 12.

[0031] The blade body 11 is a sheet-like structure with a consistent thickness, meaning that the blade body 11 as a whole has the same thickness;

[0032] The front end of the blade body 11 forms a blade tip 13, and a cutting part 12 is provided on each side of the blade body 11;

[0033] The rear end of the blade body 11 is connected to the front end of the end head 2, and the width of the rear end of the blade body 11 is the same as the diameter of the end head 2.

[0034] When using the aortic puncture punch, it can be used to puncture the aortic wall perpendicularly at the predetermined puncture location. First, the tip 13 of the blade is inserted into the aortic wall, and then it is pushed forward. The cutting parts 12 on both sides can cut the aortic wall to further enlarge the incision. The incision shape is straight. Since the width of the rear end of the blade body 11 is the same as the diameter of the end 2, after the blade 1 is fully inserted into the aortic wall, the end 2 can also be inserted into the aorta relatively smoothly.

[0035] When using the aortic puncture and punching device, by adding a sharp blade 1 to the front end of the end 2, the steps of cutting the aortic wall adventitia and cutting the aortic wall can be eliminated. The entire process only requires the aortic puncture and punching device, and the aortic puncture can be completed in one go, which is more convenient and optimizes the operation process, effectively saving surgical time.

[0036] As an optional implementation, the cutting part 12 is a blade, which is sharper and has a better cutting effect. The blade can cut the aortic wall.

[0037] As an optional implementation, the two cutting portions 12 are symmetrically arranged. The two symmetrically arranged cutting portions 12 can achieve precise cutting and effectively improve the cutting effect.

[0038] As an optional implementation, the planar shape of the blade body 11 is an isosceles triangle. This configuration allows it to cooperate with the two symmetrically arranged cutting sections 12 to achieve more precise cutting and effectively improve the cutting effect.

[0039] As an optional implementation, the rear end of the blade body 11 is fixedly connected to the front end of the tip 2. This configuration can further enhance the connection strength between the blade 1 and the tip 2, allowing them to be connected together to form a whole and thus maintain synchronous movement.

[0040] As an optional implementation, it also includes a connecting rod 3, a handle 4, a sleeve 5, a piston 6, and an elastic element 7;

[0041] The front end of the connecting rod 3 is connected to the rear end of the end 2. Preferably, the connection is an integral connection to make the connection more secure.

[0042] The connecting rod 3 is connected to the handle 4, and the two can move synchronously, which is equivalent to the synchronous movement between the pointed blade 1 and the end 2, and between the connecting rod 3 and the handle 4.

[0043] Sleeve 5 is located between connecting rod 3 and handle 4. Sleeve 5 is rotatably connected to handle 4 and connected to piston 6. Piston 6 is slidably connected to handle 4. Elastic element 7 is connected to handle 4 and piston 6 respectively. When piston 6 is pressed forward, piston 6 can move relative to handle 4 under external pressure, and at the same time can drive sleeve 5 to move forward. Sleeve 5 can also rotate relative to handle 4 while moving forward. When sleeve 5 moves to end 2, it can cooperate with end 2 to complete the cutting. When the cutting is finished, piston 6 is no longer under external pressure. At this time, elastic element 7 can drive piston 6 to rebound, and then drive sleeve 5 to move backward and return to the initial position.

[0044] As an alternative implementation, the elastic element 7 is a spring, which has good elasticity and is also less expensive.

[0045] As an optional implementation, the handle 4 is symmetrically provided with two handle portions 41 for holding, which provide a wider range of holding options and are more convenient.

[0046] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
