Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to a guidewire handle. Background Technology

[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items that are used directly or indirectly on the human body.

[0003] In vascular surgery, especially interventional cardiac artery surgery, it is necessary to measure intravascular blood pressure at fixed points in real time to accurately understand the blood conditions and help doctors accurately determine whether blood flow is obstructed and the degree of obstruction. Existing technologies have disclosed various guidewires and guidewire handles for intravascular pressure measurement. By installing a pressure sensor at the distal end of the guidewire, the blood pressure in the blood vessel is obtained based on the pressure signal from the pressure sensor, and the FFR value is calculated to assess the blood flow level of the vessel, ultimately functionally determining whether the vessel is still obstructed.

[0004] When monitoring vascular status using a pressure guidewire during treatment, a signal receiver is installed at the head of the guidewire to facilitate the smooth transmission of signals by the fiber optic pressure guidewire, and a guidewire handle is installed at the tail of the guidewire, with the end of the guidewire handle connected to a pressure sensor.

[0005] Most existing guidewire handles utilize a structure of buttons, springs, and silicone blocks. The operator presses the button with their finger, compressing the spring and applying force to the silicone block with a guide channel to compress the guidewire. However, this method cannot maintain constant pressure on the guidewire during operation, potentially leading to guidewire movement during surgery. Furthermore, excessive spring force can cause operator fatigue over time, affecting the pressure and effectiveness of the compression.

[0006] Therefore, it is necessary to provide a guide wire handle to solve the above-mentioned technical problems. Summary of the Invention

[0007] This invention provides a guidewire handle that solves the problem that current pressure guidewire handles, which use silicone blocks to press the guidewire, cannot firmly fix the pressure guidewire, potentially leading to guidewire movement during surgery.

[0008] To solve the above-mentioned technical problems, the present invention provides a guide wire handle, comprising:

[0009] The upper shell and the lower shell are provided with a second slot on opposite sides of the upper shell and the lower shell. A jumper assembly is provided inside the second slot. The jumper assembly includes a jumper connector and a jumper is connected to one end of the jumper connector.

[0010] A through groove is provided on one side opposite to the upper shell and the lower shell. An extrusion assembly is provided inside the through groove. The extrusion assembly includes a ceramic sleeve. A ceramic insert is provided inside the ceramic sleeve. A limiting ring is sleeved on the surface of the ceramic insert. A spring is sleeved on the surface of the ceramic insert.

[0011] A first slot is provided on one side opposite to the upper shell and the lower shell. A movable component is provided inside the first slot. The movable component includes a guide shaft. A threaded connector is provided at one end of the guide shaft. A collet is provided inside the guide shaft. A nut is threadedly connected to the surface of the threaded connector.

[0012] Preferably, one end of the guide shaft has a spring groove adapted to the spring, and one end of the ceramic insert is movably inserted into the guide shaft.

[0013] Preferably, the guide shaft has a guide hole inside, and one end of the nut has a guide groove.

[0014] Preferably, the guide shaft is provided with a limiting structure, and the openings of the upper and lower shells are arc-shaped openings that bend inwards. The arc-shaped openings are used to prevent the limiting structure from coming out between the upper and lower shells.

[0015] Preferably, the spring is located between the guide shaft and the limiting ring.

[0016] Preferably, the lower shell surface is connected to the upper and lower sides with snap-fit ​​blocks, and the upper shell has a snap-fit ​​groove on one side that is adapted to the snap-fit ​​blocks.

[0017] Preferably, one side of the lower shell is connected to a plurality of fixing posts, and one side of the upper shell is provided with a plurality of fixing holes that are adapted to the plurality of fixing posts.

[0018] Compared with related technologies, the wire guide handle provided by the present invention has the following beneficial effects:

[0019] This invention provides a guidewire handle, which is provided between the upper and lower shells with a jumper connector with a jumper wire, a ceramic sleeve, a ceramic insert, a limiting ring, a spring, and movable components that work together to allow the pressure guidewire to be moved to a designated position during pressure guidewire surgery. This allows for quick and secure fixation of the pressure guidewire, making it less prone to displacement. At the same time, it makes the operation easier for the operator during treatment and does not affect their work status. Attached Figure Description

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0034] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 ,in, Figure 1 This is a schematic diagram of a preferred embodiment of a guide wire handle provided by the present invention; Figure 2 for Figure 1 The diagram shows the structure of the active component. Figure 3 for Figure 2 The diagram shows the internal structure of the guide shaft. Figure 4 for Figure 1 The diagram shows the overall internal structure of the device. Figure 5 for Figure 1 A three-dimensional structural diagram of the overall device shown; Figure 6 for Figure 5 The diagram shows a cross-sectional view of the overall device. A guide wire handle includes:

[0035] The upper shell 1 and the lower shell 2 each have a second slot 3 on opposite sides. A jumper assembly 4 is housed inside the second slot 3. The jumper assembly 4 includes a jumper connector 41, one end of which is connected to a jumper wire 42. A guide wire connects to the jumper connector 41 to transmit signals (the jumper assembly is existing technology and will not be described in detail here). The end of the jumper wire 42 away from the jumper connector 41 is connected to a pressure sensor to receive signals transmitted from the guide wire. A through groove 5 is formed on opposite sides of the upper shell 1 and the lower shell 2. The through groove 5 contains... An extrusion assembly 6 is provided, which includes a ceramic sleeve 61. A ceramic insert 62 is disposed inside the ceramic sleeve 61. A limiting ring 63 is fitted on the surface of the ceramic insert 62, and a spring 64 is fitted on the surface of the ceramic insert 62. A first slot 7 is provided on one side opposite to the upper shell 1 and the lower shell 2. A movable assembly 8 is disposed inside the first slot 7. The movable assembly 8 includes a guide shaft 81. A threaded connector 82 is provided at one end of the guide shaft 81. A collet 9 is disposed inside the guide shaft 81. A nut 10 is threadedly connected to the surface of the threaded connector 82. The first slot 7, the through slot 5, and the second slot 3 are connected. When the fiber optic guide wire is inserted, ensuring full contact with the patch cord assembly, the guide shaft 81 moves towards the nut 10 within the first slot 7 as the nut 10 and threaded connector 82 are tightened. The collet 9 abuts against the inner side of the nut 10, thus pressing the collet 9 circumferentially against the structure of the nut 10 and threaded connector 82, fixing the fiber optic guide wire in place. Simultaneously, due to the action of the spring 64 and the limiting ring 63, the ceramic ferrule 62 moves at one end of the guide shaft 81, abutting against the patch cord assembly 4 for signal transmission. The other end of the patch cord connector 41 is connected to the ceramic ferrule 62 via the ceramic sleeve 61, and the other end of the spring 64 contacts the spring groove 83 on the guide shaft 81. One end of the guide shaft 81 has a spring groove 83 adapted to the spring 64, and one end of the ceramic ferrule 62 is movably inserted into the guide shaft 81. The guide shaft 81 has a guide hole 15 inside, and the nut 10 has a guide groove at one end. A limiting structure is provided on the guide shaft 81. The openings of the upper shell 1 and the lower shell 2 are curved inwards, forming an arc-shaped notch to prevent the limiting structure from dislodging between the upper shell 1 and the lower shell 2. The spring 64 is located between the guide shaft 81 and the limiting ring 63. The lower shell 2 has snap-fit ​​blocks 11 connected to both its upper and lower surfaces. One side of the upper shell 1 has a snap-fit ​​groove 12 that matches the snap-fit ​​blocks 11. Multiple fixing posts 13 are connected to one side of the lower shell 2, and multiple fixing holes 14 that match the fixing posts 13 are opened on one side of the upper shell 1. The snap-fit ​​blocks 11, snap-fit ​​grooves 12, fixing posts 13, and fixing holes 14 facilitate the connection and fixation between the upper shell 1 and the lower shell 2.

[0036] The guidewire passes through the nut 10 and guide shaft 81 sequentially into the ceramic ferrule 62. Since the guidewire used in this product is a fiber optic pressure guidewire, it transmits signals via fiber optics. During use by the doctor, the signal from the tip of the guidewire needs to be transmitted to the receiving device. The receiving device also leads out a fiber optic cable and inserts it into the ceramic ferrule 62 outside the guidewire handle. Using the elastic force of the spring 64, the jumper 42 connector 41 is tightly pressed against the end face of the ceramic ferrule 62 to achieve signal transmission. To fix the pressure guidewire, the nut 10 is turned so that the inclined surface inside the nut 10 presses against the collet 9, thus pressing the pressure guidewire. The guidewire handle is used to adjust the position of the guidewire end in the ceramic ferrule 62 inside the guidewire handle. When the doctor has adjusted the position, the guidewire can be fixed through the guidewire handle. The guide groove facilitates the insertion of the guidewire, and the guide shaft 81 has a guide hole inside to facilitate the guidewire entering the guide sleeve.

[0037] Compared with related technologies, the wire guide handle provided by the present invention has the following beneficial effects:

[0038] This invention provides a guidewire handle, in which a jumper connector 41 with a jumper wire 42, a ceramic sleeve 61, a ceramic insert 62, a limiting ring 63, a spring 64, and a movable component 8 are arranged between the upper shell 1 and the lower shell 2. These components work together to quickly and securely fix the pressure guidewire during pressure guidewire surgery, making it less prone to displacement. At the same time, it is easier for the operator to operate during treatment without affecting their work status.
