Description

TECHNICAL FIELD

[0001] The application relates to the technical field of cardiovascular internal medicine, and particularly relates to a guide wire separation device for coronary intervention surgery. BACKGROUND

[0002] Coronary intervention surgery is a complex and delicate medical procedure commonly used for diagnosing and treating coronary artery diseases. During this process, a catheter is precisely inserted into the patient's body to reach the diseased area for necessary treatment. To ensure that the catheter can smoothly enter and be accurately positioned, doctors usually insert multiple guide wires inside the catheter.

[0003] However, in actual operation, multiple guide wires inside the catheter are prone to entanglement. Since guide wires usually have considerable flexibility and length, they can easily intertwine with each other when moving inside the catheter, forming a complex entanglement structure. This guide wire entanglement not only increases the difficulty of the operation, but also may lead to the extension of the operation time, thereby increasing the risk of the patient and the uncertainty of the operation.

[0004] Therefore, the application provides a guide wire separation device for coronary intervention surgery to solve the above problems. CONTENT OF THE UTILITY MODEL

[0005] The application provides a guide wire separation device for coronary intervention surgery, which aims to solve the problem that the existing guide wires usually have considerable flexibility and length, and are prone to intertwine with each other when moving inside the catheter, forming a complex entanglement structure. This guide wire entanglement not only increases the difficulty of the operation, but also may lead to the extension of the operation time, thereby increasing the risk of the patient and the uncertainty of the operation.

[0006] To achieve the above-mentioned purpose, the application provides the following technical solution: a guide wire separation device for coronary intervention surgery, comprising a catheter, a fixing seat sleeved on the catheter, and a separation structure for separating multiple guide wires.

[0007] In order to separate several guide wires located in the catheter and prevent the guide wires from winding: the separation structure comprises a plurality of through holes in annular array opened on the catheter, a tapered tube arranged at one end of the fixing seat away from the catheter, and a feeding slot opened on the tapered tube and corresponding to the through holes for guiding the guide wire into the through hole. In use, the doctor first installs the coronary intervention surgery guide wire separation device of the application on the catheter and ensures that the fixing seat is firmly connected with the catheter. Then, the doctor guides each guide wire into the corresponding through hole from the feeding slot. Due to the cooperation of the through hole and the feeding slot, the adjacent guide wires are effectively separated, avoiding the winding phenomenon between the guide wires. The guide wire separation device is simple in structure and convenient to operate, which can effectively prevent the guide wires from winding in the catheter and improve the safety and success rate of the operation. By arranging the through holes in annular array, the adjacent guide wires are kept a certain distance apart, avoiding direct contact and winding between the guide wires. The design of the tapered tube and the feeding slot makes the installation process of the guide wire more convenient and efficient, improving the efficiency of the operation.

[0008] Preferably, in order to facilitate the insertion of the guide wire into the feeding slot: the feeding slot is in the shape of a conical hole. This design makes the guide wire enter the feeding slot more smoothly, and due to the gradual reduction of the hole diameter, the guide wire can be more accurately guided into the corresponding through hole, reducing the difficulty and error of operation.

[0009] Preferably, in order to facilitate the fixation of the tapered tube on the fixing seat: a sleeve is fixedly sleeved on one end of the tapered tube close to the fixing seat, and the other end of the sleeve is sleeved on the fixing seat away from the tapered tube. The sleeve fixing structure ensures the stable connection between the tapered tube and the fixing seat, simplifies the installation and disassembly process of the tapered tube, and improves the convenience and efficiency of the operation.

[0010] Preferably, in order to ensure the stability of the connection between the tapered tube and the fixing seat: a protruding ring is fixedly connected to one end of the tapered tube close to the fixing seat corresponding to the side of the through hole, and an insertion slot is opened at one end of the through hole close to the tapered tube for inserting the protruding ring. This design not only enhances the connection strength between the tapered tube and the fixing seat, but also ensures the accurate positioning of the tapered tube on the fixing seat, preventing it from shaking or falling off during the operation. At the same time, the cooperation of the protruding ring and the insertion slot also simplifies the installation and disassembly process of the tapered tube, improving the efficiency and convenience of the operation.

[0011] Preferably, in order to facilitate the operation of the fixing seat: a circular ring is fixedly connected to the fixing seat for positioning the thumb. The design of the circular ring provides a convenient operation means for the doctor, allowing the doctor to easily operate the fixing seat through the thumb, such as rotating, moving, etc., to achieve precise control of the entire device, further improving the efficiency and safety of the operation.

[0012] Preferably, the end of the catheter away from the fixing seat has a fluid guide groove, and an infusion tube communicating with the fluid guide groove is fixedly inserted into the catheter. The addition of the fluid guide groove and infusion tube structure meets the needs of irrigation, angiography, etc. during the operation, provides doctors with more surgical operation tools, and further improves the safety and success rate of the operation.

[0013] The guidewire separation device of this application has a simple structure and is easy to operate. It can effectively prevent guidewires from becoming entangled inside the catheter, improving the safety and success rate of the surgery. By setting a ring-shaped array of through holes, a certain distance is maintained between adjacent guidewires, avoiding direct contact and entanglement between them. The design of the tapered tube and the feeding groove makes the guidewire installation process simpler and faster, improving the efficiency of the surgery. Attached Figure Description

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] This embodiment provides a guidewire separation device for coronary interventional surgery, such as... Figures 1-5As shown, the guide wire separation device comprises a catheter 1, a fixed seat 2 sleeved on the catheter 1, and a separation structure 3 for separating a plurality of guide wires.

[0023] In order to separate the guide wires in the catheter 1 and prevent the guide wires from winding each other, the separation structure 3 comprises a plurality of through holes 31 arranged in a ring array on the catheter 1, a tapered tube 32 arranged at one end of the fixed seat 2 away from the catheter 1, and a feeding slot 33 arranged on the tapered tube 32 and corresponding to the through holes 31 for guiding the guide wires into the through holes 31. The number of the through holes 31 matches the number of the guide wires to be inserted, and the diameter of each through hole 31 is slightly larger than the diameter of the guide wire to ensure smooth passage. The through holes 31 are arranged in a ring array on the catheter 1, maintaining a certain distance between adjacent through holes 31 to avoid contact and winding of the guide wires inside the catheter 1. The tapered tube 32 gradually narrows the opening of the feeding slot 33, facilitating the accurate introduction of the guide wire into the corresponding through hole 31 during the operation. At the same time, the design of the tapered tube 32 also increases the stability of the device, preventing it from shaking or falling off during the operation. The feeding slot 33 corresponds to the through hole 31, and its width is slightly larger than the diameter of the guide wire to ensure that the guide wire can smoothly slide from the feeding slot 33 into the corresponding through hole 31. The arrangement of the feeding slot 33 not only simplifies the installation process of the guide wire, but also improves the efficiency of the operation. In use, the doctor first installs the guide wire separation device for coronary intervention surgery of the present application on the catheter 1 and ensures that the fixed seat 2 is firmly connected with the catheter 1. Then, the doctor introduces each guide wire into the corresponding through hole 31 from the feeding slot 33. Due to the cooperation of the through hole 31 and the feeding slot 33, adjacent guide wires are effectively separated, avoiding the winding phenomenon between the guide wires. The guide wire separation device is simple in structure and easy to operate, which can effectively prevent the guide wires from winding inside the catheter 1, improve the safety and success rate of the operation. By arranging the through holes 31 in a ring array, the adjacent guide wires maintain a certain distance, avoiding direct contact and winding between the guide wires. The design of the tapered tube 32 and the feeding slot 33 makes the installation process of the guide wire more convenient and efficient, improving the efficiency of the operation.

[0024] The inner wall of the through hole 31 is lined with soft polymer material (such as silicone or polyurethane). This material not only has excellent biocompatibility, which can reduce the friction damage to the surface of the guide wire, but also provides certain elastic buffer, making the guide wire more smooth when passing through the through hole 31, reducing the jamming and resistance.

[0025] Further, in order to facilitate the insertion of the guide wire into the feeding slot 33, the feeding slot 33 is in the shape of a conical hole. This design allows the guide wire to enter more smoothly when inserted into the feeding slot 33, and due to the gradual reduction of the hole diameter, the guide wire can be more accurately guided into the corresponding through hole 31, reducing the difficulty and error of operation.

[0026] Specifically, in order to facilitate the fixation of the conical tube 32 on the fixed seat 2, a sleeve 321 is fixedly sleeved on the end of the conical tube 32 close to the fixed seat 2, and the sleeve 321 is sleeved on the fixed seat 2 away from the conical tube 32. The sleeve 321 fixing structure ensures the stable connection between the conical tube 32 and the fixed seat 2, simplifies the installation and disassembly process of the conical tube 32, and improves the convenience and efficiency of the operation. When installing, the conical tube 32 is sleeved on the fixed seat 2 through the sleeve 321, ensuring the stable connection between the conical tube 32 and the fixed seat 2.

[0027] More specifically, in order to ensure the stability of the connection between the conical tube 32 and the fixed seat 2, a protruding ring 322 is fixedly connected to the side of the through hole 31 close to the end of the conical tube 32, and a insertion slot 311 is provided on the end of the through hole 31 close to the conical tube 32 for the insertion of the protruding ring 322. This design not only enhances the connection strength between the conical tube 32 and the fixed seat 2, but also ensures the accurate positioning of the conical tube 32 on the fixed seat 2, preventing it from shaking or falling off during the operation. At the same time, the cooperation of the protruding ring 322 and the insertion slot 311 also simplifies the installation and disassembly process of the conical tube 32, improving the efficiency and convenience of the operation. When installing, the conical tube 32 is inserted into the insertion slot 311 on the end of the through hole 31 close to the conical tube 32 through the protruding ring 322 on it, ensuring the stable connection between the conical tube 32 and the fixed seat 2.

[0028] Specifically, in order to facilitate the operation of the fixed seat 2, a circular ring 4 for positioning the thumb is fixedly connected to the fixed seat 2. The design of the circular ring 4 provides a convenient operation means for the doctor, so that the doctor can easily operate the fixed seat 2 by the thumb, such as rotating, moving and other actions, to realize accurate control of the entire device, further improving the efficiency and safety of the operation. In use, the doctor places the thumb on the circular ring 4, easily operates the fixed seat 2 to rotate, move and other actions through the positioning support provided by the circular ring 4, in order to adjust the device to the best position.

[0029] Specifically, the catheter 1 is provided with a liquid guide groove 5 at the end away from the fixing base 2, and a liquid infusion tube 51 is fixedly inserted on the catheter 1 and communicates with the liquid guide groove 5. The increase of the structure of the liquid guide groove 5 and the liquid infusion tube 51 meets the needs of flushing, imaging and other operations in the surgical process, provides more surgical operation means for the doctors, and further improves the safety and success rate of the surgery. When the flushing or imaging operation is needed, the doctors can connect the source of the liquid such as the flushing liquid and the contrast medium to the other end of the liquid infusion tube 51, and open the liquid source. In this way, the liquid will flow into the liquid guide groove 5 through the liquid infusion tube 51, and smoothly enter the patient's body, meeting the needs of flushing, imaging and other operations in the surgical process.

[0030] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
