Description

Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to a medical device delivery device. Background Technology

[0002] When installing a rapid exchange balloon, you need to first control the guidewire to disengage from the drive mechanism, then control the head end of the rapid exchange balloon to pass through the tail end of the guidewire, and the tail end of the guidewire to pass through the rapid exchange port of the rapid exchange balloon. Then, move the rapid exchange balloon along the guidewire towards the drive mechanism. Finally, the rapid exchange balloon enters the drive mechanism.

[0003] During the installation of a rapid exchange balloon, the guidewire tip needs to be fixed to ensure safety, meaning the guidewire tip cannot be displaced. However, the guidewire is not fixed during installation, and whether the guidewire tip moves depends on the operator's control. Therefore, the installation of a rapid exchange balloon has high requirements and is difficult. Summary of the Invention

[0007] During device installation, the guidewire front end fixing mechanism clamps the guidewire, inserts the head end of the rapid exchange balloon through the tail end of the guidewire, and the tail end of the guidewire exits through the rapid exchange port of the rapid exchange balloon. The guidewire front end fixing mechanism releases the guidewire, and the portion of the rapid exchange balloon before the rapid exchange port enters the drive mechanism.

[0008] Furthermore, the driving mechanism includes a catheter delivery device, and the catheter delivery device and the guidewire tip fixing mechanism are arranged sequentially;

[0010] During disassembly, the rapid exchange balloon is sequentially withdrawn from the catheter delivery device and the guidewire tip fixing mechanism. The guidewire tip fixing mechanism clamps the guidewire and moves the rapid exchange balloon away from the catheter delivery device along the guidewire, causing the rapid exchange balloon to withdraw from the guidewire. The guidewire tip fixing mechanism then releases the guidewire.

[0036] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0037] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0038] This application provides a medical device delivery device, such as... Figure 1 and Figure 2 As shown, the medical device delivery device includes: a drive mechanism 1 and a guidewire front end fixing mechanism 2; the guidewire front end fixing mechanism 2 is used to clamp or release the guidewire a.

[0039] When installing the device, the guidewire front end fixing mechanism 2 clamps the guidewire a, inserts the head end of the rapid exchange balloon from the tail end of the guidewire, and the tail end of the guidewire exits the rapid exchange port of the rapid exchange balloon. The guidewire front end fixing mechanism 2 releases the guidewire a, and the portion of the rapid exchange balloon before the rapid exchange port enters the drive mechanism 1.

[0040] The beneficial effects of the medical device delivery device provided in this application embodiment are as follows: When installing the rapid exchange balloon, the guide wire a is fixed by the guide wire front end fixing mechanism 2 to prevent the guide wire a from moving away from the lesion position when the rapid exchange balloon moves relative to the guide wire a, avoids the guide wire a being repeatedly placed in the lesion position, increases the stability of the guide wire a, reduces the difficulty of operation, and thus improves the efficiency, accuracy and safety of the surgery.

[0041] like Figure 1 and Figure 2 As shown, the driving mechanism 1 further includes a catheter delivery device 11, and the catheter delivery device 11 and the guidewire front end fixing mechanism 2 are arranged in sequence.

[0042] When installing the device, the guidewire front-end fixing mechanism 2 clamps the guidewire a, inserts the head end of the rapid exchange balloon through the tail end of the guidewire a, and the tail end of the guidewire a exits the rapid exchange port of the rapid exchange balloon; the guidewire front-end fixing mechanism 2 releases the guidewire a, and the portion of the rapid exchange balloon before the rapid exchange port passes through the guidewire front-end fixing mechanism 2 and enters the catheter delivery device 11.

[0043] During disassembly, the rapid exchange balloon is sequentially withdrawn from the catheter delivery device 11 and the guidewire tip fixing mechanism 2. The guidewire tip fixing mechanism 2 clamps the guidewire a and moves the rapid exchange balloon along the guidewire a in a direction away from the catheter delivery device 11, so that the rapid exchange balloon is withdrawn from the guidewire a. The guidewire tip fixing mechanism 2 then releases the guidewire a.

[0044] In this embodiment, when installing the rapid exchange balloon, the tip of guidewire a is first fixed by the guidewire tip fixing mechanism 2 to prevent displacement of the tip of guidewire a during the insertion of the rapid exchange balloon from the tail end of guidewire a. When removing the rapid exchange balloon, after the rapid exchange balloon has sequentially exited the catheter delivery device 11 and the guidewire tip fixing mechanism 2, the tip of guidewire a is again fixed by the guidewire tip fixing mechanism 2 to prevent displacement of the tip of guidewire a during the exit of the rapid exchange balloon. This embodiment reduces the operational difficulty of installing or removing the rapid exchange balloon, thereby improving the efficiency, accuracy, and safety of the surgery.

[0045] like Figure 3 and Figure 4 As shown, the guide wire front end fixing mechanism 2 further includes a mounting frame 21 and a clamping device 22. The mounting frame 21 is provided with a channel 23 for the guide wire a or the rapid exchange balloon to pass through. The clamping device 22 is movably mounted on the mounting frame 21.

[0046] When installing the device, the clamping device 22 moves toward the channel 23 to clamp the guide wire a in the channel 23, inserts the head end of the rapid exchange balloon through the tail end of the guide wire a, and the tail end of the guide wire a exits the rapid exchange port of the rapid exchange balloon. The clamping device 22 moves away from the channel 23 to release the guide wire a, and the portion of the rapid exchange balloon before the rapid exchange port passes through the channel 23 and enters the drive mechanism 1.

[0047] During disassembly, the rapid exchange balloon is removed from the drive mechanism 1 and the channel 23. The clamping device 22 moves toward the channel 23 to clamp the guide wire a within the channel 23. The rapid exchange balloon is moved along the guide wire a away from the guide wire front end fixing mechanism 2, causing the rapid exchange balloon to exit the guide wire a. The clamping device 22 moves away from the channel 23 to release the guide wire a.

[0048] In this embodiment, the clamping device 22 moves away from the channel 23 to release the guidewire a, and then passes the portion of the rapid exchange balloon before the rapid exchange port through the channel 23 and into the catheter delivery device 11.

[0049] In this embodiment, during disassembly, after the rapid exchange balloon is removed from the catheter delivery device 11 and the channel 23, the clamping device 22 moves toward the channel 23.

[0050] In this embodiment, the guide wire a is clamped or released by moving the clamping device 22 toward or away from the channel 23, which reduces the operational difficulty of the medical device delivery device.

[0051] like Figure 3 and Figure 4 As shown, the catheter delivery device 11 further includes a T valve 111 for mounting catheter b.

[0052] In this embodiment, during device installation, the portion of the rapid exchange balloon before the rapid exchange port is passed through the channel 23, and then the portion of the rapid exchange balloon before the rapid exchange port passes through the T valve 111 and enters the catheter b. During disassembly, the rapid exchange balloon is sequentially withdrawn from the T valve 111 and the channel 23.

[0053] Furthermore, the medical device delivery device also includes a rapid exchange delivery device (not shown). The catheter delivery device 11, the guidewire tip fixing mechanism 2, and the rapid exchange delivery device are arranged in sequence. The rapid exchange delivery device is used to deliver the rapid exchange balloon.

[0054] During device installation, the guidewire tip fixing mechanism 2 clamps the guidewire a, inserts the tip of the rapid exchange balloon through the tail end of the guidewire a, and the tail end of the guidewire a exits the rapid exchange port of the rapid exchange balloon; the guidewire tip fixing mechanism 2 releases the guidewire a, passes the portion of the rapid exchange balloon before the rapid exchange port through the guidewire tip fixing mechanism 2, and enters the catheter delivery device 11; the portion of the rapid exchange balloon after the rapid exchange port enters the rapid exchange delivery device.

[0055] During disassembly, the rapid exchange balloon is sequentially withdrawn from the catheter delivery device 11 and the guidewire tip fixing mechanism 2. The guidewire tip fixing mechanism 2 clamps the guidewire a and moves the rapid exchange balloon along the guidewire a in a direction away from the catheter delivery device 11, so that the rapid exchange balloon is withdrawn from the guidewire a. The guidewire tip fixing mechanism 2 then releases the guidewire a.

[0056] like Figure 3 and Figure 4As shown, the clamping device 22 further includes a first power assembly 221, a first clamping plate 222 and a second clamping plate 223 disposed on the mounting frame 21, and the channel 23 is located between the first clamping plate 222 and the second clamping plate 223; the first power assembly 221 is connected to the first clamping plate 222 and / or the second clamping plate 223, and is used to drive the first clamping plate 222 and the second clamping plate 223 to cooperate in clamping or releasing the guide wire a in the channel 23.

[0057] During device installation, the first power assembly 221 drives the first clamping plate 222 and the second clamping plate 223 to cooperate in clamping the guidewire a in the channel 23, inserting the tip of the rapid exchange balloon from the tail end of the guidewire a, and the tail end of the guidewire a exiting the rapid exchange port of the rapid exchange balloon; the first power assembly 221 drives the first clamping plate 222 and the second clamping plate 223 to cooperate in releasing the guidewire a in the channel 23, allowing the portion of the rapid exchange balloon before the rapid exchange port to pass through the channel 23 and enter the catheter delivery device 11.

[0058] During disassembly, the rapid exchange balloon is removed from the catheter delivery device 11 and the channel 23. The first power component 221 drives the first clamping plate 222 and the second clamping plate 223 to cooperate and clamp the guidewire a in the channel 23. The rapid exchange balloon is moved along the guidewire a away from the guidewire front end fixing mechanism 2, so that the rapid exchange balloon is removed from the guidewire a. The first power component 221 drives the first clamping plate 222 and the second clamping plate 223 to cooperate and release the guidewire a in the channel 23, so as to facilitate subsequent delivery of the guidewire a.

[0059] In this embodiment, the first clamping plate 222 and the second clamping plate 223 are driven by the first power component 221 to cooperate, which facilitates the clamping or release of the guide wire a in the channel 23 and reduces the operation difficulty of the medical device delivery device.

[0060] In one embodiment, the second clamping plate 223 is fixed to the mounting bracket 21; the first power assembly 221 is connected to the first clamping plate 222 and is used to drive the first clamping plate 222 to move toward or away from the second clamping plate 223 to clamp or release the guide wire a in the channel 23. Driving the first clamping plate 222 toward or away from the second clamping plate 223 by the first power assembly 221 to clamp or release the guide wire a in the channel 23 simplifies the structure of the clamping device 22, making it easier to clamp or release the guide wire a.

[0061] Furthermore, the first power assembly 221 includes a driving member 2211, a connecting member 2212, and an elastic member 2213; the driving member 2211 is disposed on the mounting bracket 21, the connecting member 2212 is connected to the output end of the driving member 2211, one end of the connecting member 2212 away from the driving member 2211 is connected to the first clamping plate 222, and the two ends of the elastic member 2213 are respectively connected to the first clamping plate 222 and the mounting bracket 21.

[0062] In this embodiment, the driving member 2211 drives the first clamping plate 222 to move toward the second clamping plate 223 via the connecting member 2212 to clamp the guide wire a in the channel 23; the driving member 2211 drives the first clamping plate 222 to move away from the second clamping plate 223 via the connecting member 2212 to release the guide wire a in the channel 23.

[0063] In this embodiment, when the first power assembly 221 is installed, the elastic member 2213 provides a pushing force to the first clamping plate 222, causing the first clamping plate 222 to move toward the second clamping plate 223, so that the first clamping plate 222 and the second clamping plate 223 are clamped and fixed, and the connecting member 2212 also remains stationary under the drive of the first clamping plate 222, so that when the drive member 2211 is installed, the output end of the drive member 2211 is connected to the connecting member 2212.

[0064] Furthermore, there are two elastic elements 2213, which are respectively disposed on both sides of the first clamping plate 222 near the end of the connector 2212, and the connector 2212 is located between the two elastic elements 2213; the two elastic elements 2213 provide the same force to both sides of the first clamping plate 222, maintaining the force balance of the first clamping plate 222.

[0065] Furthermore, the elastic element 2213 is a spring.

[0066] Optionally, the driving component 2211 is a lead screw motor, pneumatic cylinder, electromagnet, etc.; the driving component 2211 drives the first clamping plate 222 to move in a straight line toward or away from the second clamping plate 223, thereby realizing the horizontal movement of the first clamping plate 222 to clamp or release the guide wire a in the channel 23.

[0067] Optionally, the drive component 2211 includes a cam (not shown), a rotating rod (not shown), and a motor (not shown). The motor is mounted on the mounting bracket 21, the rotating rod is connected to the rotating shaft of the motor, the cam is mounted on the rotating rod, the side of the cam abuts against the first clamping plate 222, one end of the first clamping plate 222 is rotatably connected to the mounting bracket 21, and the outer diameter of the cam increases along the rotation direction of the first clamping plate 222. When the motor drives the cam to rotate clockwise or counterclockwise through the rotating rod, the cam pushes the first clamping plate 222 to rotate toward the second clamping plate 223 to clamp or release the guide wire a in the channel 23.

[0068] Furthermore, the first power assembly 221 also includes a force detection sensor (not shown), the two ends of which are connected to the output end of the drive member 2211 and the connector 2212, respectively.

[0069] In this embodiment, a force detection sensor is used to detect the clamping force applied by the first clamping plate 222 to the guide wire a, so as to prevent the first clamping plate 222 from damaging the hydrophilic coating on the surface of the guide wire a.

[0070] Optionally, the force detection sensor may employ resistance strain gauge, piezomagnetic, piezoelectric, or vibrating wire detection methods.

[0071] Furthermore, the first clamping plate 222 and the second clamping plate 223 each have a plurality of first grooves 224 on their adjacent sides, and the first grooves 224 are perpendicular to the axial direction of the guide wire a.

[0072] In this embodiment, the first groove 224 is provided so that the adjacent sides of the first clamping plate 222 and the second clamping plate 223 are both wavy. Since the guide wire a has a hydrophilic coating and low friction, the guide wire a can be effectively fixed by maintaining its state through the wavy first clamping plate 222 and the second clamping plate 223 without damaging the guide wire a.

[0073] In another embodiment, the first power assembly 221 is connected to the first clamping plate 222 and the second clamping plate 223, and is used to drive the first clamping plate 222 and the second clamping plate 223 to move in opposite directions relative to each other, so as to clamp or release the guide wire a in the channel 23. The first power assembly 221 causes the first clamping plate 222 and the second clamping plate 223 to move in opposite directions and move closer to each other, so as to achieve concentric clamping of the first clamping plate 222 and the second clamping plate 223 to clamp the guide wire a in the channel 23; or the first power assembly 221 causes the first clamping plate 222 and the second clamping plate 223 to move in opposite directions and move away from each other, so as to release the guide wire a in the channel 23.

[0074] Optionally, the first power assembly 221 includes two opposing first power members (not shown), which drive the first clamping plate 222 and the second clamping plate 223 respectively; or, the first power assembly 221 includes a second power member (not shown) and a rotating member (not shown), the rotating member being connected to the output end of the second power member, the rotating member having symmetrically arranged first and second threads, and the first clamping plate 222 and the second clamping plate 223 being respectively connected to the rotating rod through the first and second threads. Various structures can be used to drive the first clamping plate 222 and the second clamping plate 223 to move in opposite directions relative to each other, and this application does not impose any limitations on this.

[0075] like Figure 1 and Figure 2 As shown, the driving mechanism 1 further includes a guide wire delivery device 12, which is used to reciprocate the guide wire a. The guide wire front end fixing mechanism 2 and the guide wire delivery device 12 are arranged in sequence.

[0076] When the guide wire a is delivered, the guide wire delivery device 12 clamps the tail end of the guide wire a, and the guide wire front end fixing mechanism 2 releases the front end of the guide wire a. The guide wire delivery device 12 moves toward the guide wire front end fixing mechanism 2 to deliver the guide wire a. The guide wire front end fixing mechanism 2 clamps the guide wire a. The guide wire delivery device 12 releases the guide wire a. The guide wire delivery device 12 moves away from the guide wire front end fixing mechanism 2 to reset.

[0077] Repeat the steps described above for delivering the guidewire a until the guidewire a is delivered to the set position.

[0078] In existing technologies, due to the tortuousness of blood vessels and the elastic properties of guidewire a itself, guidewire a may rebound or become sluggish during advancement, retraction, or rotation. To address this issue and maintain the stability of guidewire a within the blood vessel, this application first clamps the guidewire by the guidewire front-end fixing mechanism 2 before the guidewire delivery device 12 moves away from the guidewire front-end fixing mechanism 2 to reset it. This keeps guidewire a in its current state, preventing it from rebounding and facilitating operator control over guidewire a, thus achieving surgical precision.

[0079] It should be noted that the front end and the tail end of the guide wire a are not fixed ends. Instead, the part of the guide wire a that is close to the guide wire front end fixing mechanism 2 is the front end, and the part of the guide wire a that is close to the guide wire delivery device 12 is the tail end.

[0080] Furthermore, the catheter delivery device 11, the guidewire tip fixing mechanism 2, and the guidewire delivery device 12 are arranged sequentially.

[0081] Furthermore, the catheter delivery device 11, the guidewire tip fixing mechanism 2, the quick-connect delivery device, and the guidewire delivery device 12 are arranged in sequence.

[0082] like Figure 3 and Figure 4 As shown, the guide wire delivery device 12 further includes a fixing frame 121, a second power assembly (not shown), a first movable plate 122 and a second movable plate 123. The second power assembly is disposed on the fixing frame 121 and is connected to the first movable plate 122 and the second movable plate 123. The second power assembly is used to drive the first movable plate 122 and the second movable plate 123 to move in opposite directions relative to each other to clamp or rotate the guide wire a.

[0083] When the guide wire a is delivered, the second power component drives the first movable plate 122 and the second movable plate 123 to move closer to each other, so that the first movable plate 122 and the second movable plate 123 clamp the guide wire a, and the guide wire front end fixing mechanism 2 releases the front end of the guide wire a. The guide wire delivery device 12 moves toward the guide wire front end fixing mechanism 2 to deliver the guide wire a. After the guide wire front end fixing mechanism 2 clamps the guide wire a, the second power component drives the first movable plate 122 and the second movable plate 123 to move away from each other, so that the first movable plate 122 and the second movable plate 123 release the guide wire a, and the guide wire delivery device 12 moves away from the guide wire front end fixing mechanism 2 to reset.

[0084] Repeat the steps described above for delivering the guidewire a until the guidewire a is delivered to the set position.

[0085] In this embodiment, the second power component can also drive the first movable plate 122 and the second movable plate 123 to move upward and downward respectively, so that the first movable plate 122 and the second movable plate 123 rotate the guide wire a in a stabbing manner.

[0086] In this embodiment, the first movable plate 122 and the second movable plate 123 are driven to move in opposite directions relative to each other by the second power component to clamp or rotate the guide wire a, which simplifies the structure of the guide wire delivery device 12 and makes it easy to clamp or rotate the guide wire a.

[0087] Furthermore, each of the adjacent sides of the first movable plate 122 and the second movable plate 123 is provided with a plurality of second grooves (not shown), and the second grooves are perpendicular to the axial direction of the guide wire a.

[0088] In this embodiment, the second groove is provided so that the adjacent sides of the first movable plate 122 and the second movable plate 123 are both wavy. Since the surface of the guide wire a has a hydrophilic coating and low friction, the guide wire a can be effectively fixed by maintaining its state through the wavy first movable plate 122 and the second movable plate 123 without damaging the guide wire a.

[0089] like Figure 1 and Figure 2 As shown, the medical device delivery device further includes a linear component 3, the drive mechanism 1 is mounted on the linear component 3, and the linear component 3 is used to drive the drive mechanism 1 to move linearly.

[0090] In this embodiment, the catheter delivery device 11 and the guidewire delivery device 12 are sequentially mounted on the linear assembly 3, and the guidewire front end fixing mechanism 2 is mounted on one end of the catheter delivery device 11 adjacent to the guidewire delivery device 12.
