Description

Therapeutic Devices for Cardiovascular Interventional Surgery

technical field

The utility model relates to the technical field of medical devices, in particular to a therapeutic device for cardiovascular interventional operations.

Background technique

Cardiovascular disease is one of the common diseases that threaten human health. Cardiovascular disease is also called circulatory system disease. The circulatory system refers to the organs and tissues in the human body responsible for transporting blood, such as the heart and blood vessels. In the prior art, the treatment methods for cardiovascular diseases generally include surgery and interventional therapy. Compared with surgical treatment, interventional therapy has the advantages of less trauma, less pain and faster recovery, so the existing cardiovascular diseases mostly use interventional therapy. .

In the prior art, when performing cardiovascular interventional treatment, a puncture needle is often used to directly puncture a blood vessel, and then a guide wire is passed through the puncture needle, thereby sending the guide wire into the blood vessel. In the above method, after the puncture needle is inserted into the blood vessel, a lot of blood is likely to flow out of the puncture needle and pollute the operation surface; since the puncture needle is filled with blood, it will block the doctor's operating field of vision, and the guide wire will easily be shifted during puncture, making the The doctor cannot smoothly insert the guide wire into the puncture needle, which reduces the puncture efficiency.

Utility model content

The utility model intends to provide a treatment device for cardiovascular interventional surgery to solve the problem in the prior art that blood flows out and pollutes the operating surface during puncture, which affects the doctor's operation.

In order to achieve the above object, the utility model provides the following technical solutions:

A therapeutic device for cardiovascular interventional operations, including a puncture needle, which is provided with an isolation mechanism for isolating blood. The puncture needle outside the isolation mechanism is provided with a liquid outlet, and the fluid outlet is located on the side of the isolation mechanism close to the needle. The liquid hole is connected with a liquid guiding mechanism.

The principles and beneficial effects of this program are:

The puncture needle is used to penetrate into the cardiovascular system to introduce the guide wire, and the isolation mechanism is used to isolate the blood to prevent the blood from flowing directly out of the puncture needle, preventing the inside of the puncture needle from being filled with blood and blocking the doctor's view; the blood entering the puncture needle is isolated due to The mechanism blocks it, so it can only flow from the liquid outlet to the liquid guiding mechanism. If there is no blood in the puncture needle, it will not block the doctor's field of vision, which is convenient for the doctor to insert the guide wire. The blood collection mechanism is externally connected to the liquid guide mechanism, and the blood is guided to the external blood collection device, which can prevent the blood from contaminating the operation surface.

Further, the isolation mechanism is an isolation sleeve, and the isolation sleeve is provided with guide wire holes for the guide wire to pass through. The isolation sleeve is used to isolate the blood and prevent the blood from flowing out directly from the puncture needle; the guide wire hole is used to insert the guide wire. Medium offset and wobble.

Further, the spacer sleeve is in the shape of a circular platform, the small-diameter end of the circular platform is close to the needle head of the puncture needle, the large-diameter end of the circular platform is connected with the puncture needle, the guide wire hole is arranged on the small-diameter end of the circular platform, and the liquid outlet is arranged on both ends of the large-diameter end of the circular platform. side. The frustum-shaped isolation sleeve can play a role of "separation" for the blood entering the puncture needle. When the blood flows to the frustum-shaped isolation sleeve, the blood can flow to the outside of the isolation sleeve under the action of the isolation sleeve, so that It can prevent blood from entering the guide wire hole; the liquid outlet hole is set on the side of the isolation sleeve close to the needle, and the blood that is "shunted" to the outside of the isolation sleeve can flow away directly from the outlet hole, reducing the chance of blood staying in the puncture needle Time can prevent excessive blood accumulation from entering the guide wire hole.

Further, the small-diameter end of the spacer sleeve is elastic, the guide wire hole is a conical hole, and the small-diameter end of the guide wire hole is close to the needle of the puncture needle. The guidewire hole adopts a conical hole, and it is difficult for blood to flow in from the small-diameter end of the guidewire hole, but it is more convenient to insert the guidewire from the large-diameter end of the guidewire hole; in addition, the small-diameter end of the isolation sleeve is elastic, It is also possible to use the guide wire to stretch the guide wire hole without affecting the guide wire insertion; and the aperture of the guide wire hole in a free state will be smaller than the aperture when the guide wire is inserted, thereby further improving the effect of the isolation sleeve on blocking blood.

Further, the axis of the guide wire hole coincides with the axis of the puncture needle. This can prevent the guide wire from abutting against the inner wall of the puncture needle after passing through the guide wire hole, thereby ensuring that the guide wire can pass through the puncture needle smoothly.

Further, the liquid guide mechanism is a guide channel opened in the wall of the puncture needle, and one end of the guide channel extends to the tail of the puncture needle. The diversion channel is used to guide the blood flow out, and the diversion channel extends to the needle tail to facilitate the external connection of the blood collection device; the diversion channel is directly set on the needle wall of the puncture needle, which can reduce the volume of the utility model compared with other mechanisms , easy to operate, and will not block the doctor's field of vision.

Further, the other end of the diversion channel is located at the communication place between the diversion channel and the liquid outlet hole. After the blood flows into the diversion channel from the liquid outlet hole, it can directly flow along the diversion channel to the tail of the puncture needle without returning to the needle head, which reduces the accumulation of blood in the diversion channel.

Further, the needle tail of the puncture needle is provided with a connection hole, and the connection hole communicates with the flow guiding channel. The connection hole is used for externally connecting the blood collection device.

Further, the needle tail of the puncture needle is covered with a non-slip sleeve. The anti-slip sleeve can increase the friction between the hands of the medical staff and the puncture needle, prevent the hands of the medical staff from slipping during operation, and improve the stability of the operation.

Further, the anti-slip sleeve is provided with a plurality of annular protrusions. In this way, the anti-slip performance of the anti-slip sleeve can be further improved.

Detailed ways

The following is further described in detail through specific implementation methods:

The reference signs in the accompanying drawings of the description include: anti-slip sleeve 1, puncture needle 2, diversion channel 3, liquid outlet hole 4, isolation sleeve 5, guide wire hole 6.

Embodiment is shown in Figure 1 basically:

The therapeutic device for cardiovascular interventional surgery of the utility model comprises a puncture needle 2, and an anti-slip sleeve 1 is provided on the needle tail of the puncture needle 2 to prevent the hands of medical personnel from slipping when holding the 2 needles of the puncture needle. Having a plurality of annular protrusions can further improve the anti-slip effect of the anti-slip sleeve 1 . An isolation mechanism for isolating blood is installed in the puncture needle 2, and the isolation mechanism is arranged close to the needle head. The isolation mechanism is an isolation sleeve 5, and the isolation sleeve 5 is in the shape of a circular platform. The puncture needle 2 is connected. The small-diameter end of the spacer 5 has elasticity, and the small-diameter end of the spacer 5 in the present embodiment is made of rubber, and the small-diameter end of the spacer 5 is provided with a guide wire hole 6 for the guide wire to pass through. The guide wire hole 6 is Conical hole, the small-diameter end of the guide wire hole 6 is close to the needle head of the puncture needle 2, and the axis of the guide wire hole 6 coincides with the axis of the puncture needle 2.

The puncture needle 2 on the outer side of the isolation sleeve 5 is provided with a liquid outlet hole 4, which is located on the side of the isolation sleeve 5 close to the needle, and the liquid outlet hole 4 is connected with a liquid guide mechanism, which is opened on the puncture needle 2. Diversion channel 3 in the wall. The left end of the diversion channel 3 extends to the needle tail of the puncture needle 2, the right end of the diversion channel 3 is located at the connection between the diversion channel 3 and the outlet hole 4, and the needle tail of the puncture needle 2 is provided with a connecting hole, and the connecting hole and the guide Flow channel 3 communicates.

In practical application, connect the catheter in the connection hole to connect the blood collection device externally, and then the medical personnel hold the puncture needle 2 and puncture the patient's cardiovascular system. The anti-slip sleeve 1 on the puncture needle 2 can prevent the hand of the medical personnel from slipping during operation, improving operational stability. The blood flowing from the blood vessel into the puncture needle 2 during puncture can be blocked by the frustum-shaped isolation sleeve 5. Although the small-diameter end of the isolation sleeve 5 is provided with a guide wire hole 6, the guide wire hole 6 is a conical hole, and its small-diameter end is located in the isolation sleeve. At the small-diameter end of the sleeve 5, and because the isolation sleeve 5 is in the shape of a truncated cone, the blood flowing to the isolation sleeve 5 can be "shunted" to the outside of the isolation sleeve 5 under the action of the isolation sleeve 5, so the blood cannot pass through the guide wire hole. 6 flow into the spacer 5.

In addition, the blood that is "shunted" to both sides of the isolation sleeve 5 can quickly flow from the liquid outlet hole 4 outside the isolation sleeve 5 into the diversion channel 3, and finally flow along the diversion channel 3 to the external blood collection device . Therefore, the blood flowing out during puncturing will not flow out from the puncture needle 2 to the operation surface, and the inside of the puncture needle 2 will not be polluted by blood to block the doctor's field of vision. Because the operation surface is polluted and the doctor's field of vision is blocked, it is convenient for the doctor to operate.

After the puncture needle 2 penetrates into the blood vessel, the medical staff can insert the guide wire into the puncture needle 2 from the tail end, and make the guide wire pass through the guide wire hole 6, and finally insert it into the blood vessel. The small-diameter end of the isolation sleeve 5 is elastic, and the guide wire hole 6 is opened at the small-diameter end of the isolation sleeve 5. When the guide wire is inserted into the guide wire hole 6, the guide wire hole 6 can be forced to deform so as to expand the guide wire hole 6 Therefore, the aperture of the guide wire hole 6 is smaller than the aperture when the guide wire is inserted in a free state, which can further improve the effect of the isolation sleeve 5 on isolating blood. After the guide wire passes through the guide wire hole 6, the spacer 5 at the guide wire hole 6 can clamp the guide wire due to its elastic recovery deformation, thereby providing support for the guide wire and preventing the guide wire from being damaged during the puncture process. Shake to avoid deflection of the puncture. In addition, the isolation sleeve 5 with the guide wire hole 6 can also guide the medical staff when guiding the wire: the guide wire passing through the guide wire hole 6 means that the guide wire does not deviate, which ensures the accuracy of the puncture Moreover, the axis of the guide wire hole 6 coincides with the axis of the puncture needle 2, which can prevent the guide wire from being stuck against the inner wall of the puncture needle 2 after passing through the guide wire hole 6 and cause the guide wire to be stuck, ensuring the safety of the guide wire. Imported smoothly.

The utility model realizes the blocking and shunting of the blood, as well as the guiding and positioning of the guide wire by arranging a conical isolation sleeve 5 in the puncture needle 2, so as to avoid the blood flowing to the operation surface during puncture and affect the doctor's operation, and at the same time It can avoid deviation when the guide wire is inserted.
