Description

Pulse generator take-up device and pulse generating system Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a pulse generator wire-receiving device and a pulse generating system. Background Art

[0002] Existing medical pulse generators are generally connected to electrode wires, which transmit signals between the human body and the pulse generator. For example, pulse generators are used in implantable cardiac pacemaker systems, temporary cardiac pacemaker systems, brain pacemaker systems, etc. Since electrode wires are non-customized products, taking implantable cardiac pacemaker systems as an example, after the pacemaker (i.e., pulse generator) is implanted, a certain length of the tail end usually protrudes from the implantation incision. After connecting to the electrical connector of the pulse generator, the excess length of the electrode wire is coiled on the surface of the pulse generator and placed in the pouch together with the pulse generator.

[0003] After the pulse generator and the coiled electrode wires are stuffed into the narrow space of the pouch, the electrode wires coiled around the pulse generator will become loose as the pouch is worn on the human body and the human body moves. Relative movement will occur between the electrode wires and the metal casing of the pulse generator, resulting in friction. Long-term friction can cause the insulation layer of the electrode wires to rupture or even the conductor to break. Existing pulse generators do not have a dedicated electrode wire storage structure. In actual use, they are all manually coiled, and the coiling method is affected by personal habits, resulting in huge differences in the coiling methods of different people. This results in irregular coiling of the electrode wires, resulting in different coiling curvatures. Even coiled electrode wires will be rolled up in a disorderly manner during the process of being stuffed into the pouch, which may cause the electrode wires to be locally over-bent. This over-bent part has a high probability of rupturing the insulation layer or breaking the electrode wire after long-term stress. It also causes the pulse generator pouch area to bulge, which can easily cause abrasion of the human skin and affect the appearance.

[0004] In view of the above technical defects, a pulse generator winding device and a pulse generating system are needed to facilitate and regularly store the electrode wires. This can prevent friction between the electrode wires and the pulse generator, and facilitate and quickly store the electrode wires. When the pulse generator is placed in the pouch, the volume of the pouch can also be effectively reduced, making the pouch easy to use and more beautiful. Summary of the Invention

[0005] The present invention provides a pulse generator wire-retracting device and a pulse generating system. The wire-retracting device allows the electrode wires to be conveniently and regularly stored, thereby preventing friction between the electrode wires and the pulse generator and conveniently and quickly storing the electrode wires. When the pulse generator is placed in a pouch, the volume of the pouch can also be effectively reduced, making the pouch convenient to use and more beautiful.

DETAILED DESCRIPTION

[0026] The following is a detailed description of the pulse generator wire take-up device proposed in the present invention, with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are highly simplified and not to exact scale, and are intended solely to facilitate and clarify the purpose of illustrating the embodiments of the present invention.

Therefore, features specified as "first", "second", and "third" may explicitly or implicitly include one or at least two of the features. In addition, as used in the present invention, "mounted", "connected", "connected", and one element "disposed" on another element should be understood broadly and generally only indicate that there is a connection, coupling, mating, or transmission relationship between the two elements, and the connection, coupling, mating, or transmission between the two elements can be direct or indirect through an intermediate element. It should not be understood to indicate or imply a spatial positional relationship between the two elements, that is, one element can be in any orientation such as inside, outside, above, below, or to the side of another element, unless the content clearly indicates otherwise. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, directional terms such as above, below, up, down, upward, downward, left, right, etc. are used with respect to the exemplary embodiments as they are shown in the figures, with the upward or upper direction being toward the top of the corresponding figure and the downward or lower direction being toward the bottom of the corresponding figure.

[0029] In this embodiment, the axial direction is based on the central axis of rotation of the rotating member.

[0030] The pulse generator wire-winding device in this embodiment can be applied to a pulse generating system, which may be a brain pacemaker system, a cardiac pacemaker system, or a temporary cardiac pacemaker system.

[0031] This embodiment is described by taking a temporary pacing system as an example. The temporary pacing system includes a wire winding device of a pulse generator;

[0032] The wire winding device of the pulse generator includes: a wire winding part 10 and a rotating part 20;

[0033] Please refer to FIGS. 1 and 2. The wire winding part 10 includes a body 11, an end cover 12 and an outer edge 13. The outer contour of the body 11 is cylindrical, the end cover 12 is disc-shaped, and the rotating part 20 is annular. The three are coaxially arranged. The outer peripheral surface of the second axial end (the lower end of the body 11 in FIGS. 1 and 2) of the body 11 has an annular outer edge 13 extending radially outward. Therefore, the outer edge 13 and the outer peripheral surface of the body 11 form an annular notch with an "L" - shaped cross section. And this notch communicates along the axial direction of the body 11 to the first end (the upper end of the body 11 in FIGS. 1 and 2) of the body 11 along the axial direction; the end cover 12 is arranged at the first end (the upper end of the body 11 in FIGS. 1 and 2) of the body 11. The end cover 12 and the outer edge 13 are axially opposite. Therefore, the end cover 12, the outer peripheral surface of the body 11 and the outer edge 13 form the wire winding groove 15. The wire winding groove 15 is integrally annular, and the cross section of the wire winding groove 15 is approximately "匚" - shaped.

[0034] A first wire hole 14 communicating with the wire winding groove 15 is formed on the wire winding part 10; the first wire hole 14 is used for connecting an electrode lead or for the electrode lead to pass through.

[0035] Please continue to refer to FIG. 1. The rotating part 20 covers the wire winding groove 15 to form an annular storage cavity for accommodating the electrode lead.

[0036] The rotating part 20 is rotatably arranged on the wire winding part 10 around the wire winding groove 15. A second wire hole 21 communicating with the wire winding groove 15 is formed on the rotating part 20. The second wire hole 21 is used for the electrode lead to pass through. Therefore, when the first wire hole 14 and the second wire hole 21 are aligned, the electrode lead directly passes through the first wire hole 14 and the second wire hole 21 into the interior of the wire winding device of the pulse generator. As shown in FIG. ①, when the rotating part 20 rotates relative to the body 11, the first wire hole 14 and the second wire hole 21 are misaligned, and the edge of the second wire hole 21 will squeeze the electrode lead, forcing a part of the electrode lead to enter the wire winding groove 15 and wind orderly along the wire winding groove 15. Similarly, when the rotating part 20 rotates in the opposite direction relative to the body 11, the electrode lead can be released.

[0037] The above structure eliminates the need for individual coiling habits to store the electrode leads, allowing for standardized electrode lead storage. During rotation of the rotating portion 20, the electrode leads can be conveniently and regularly stored or released. This prevents loose electrode leads from rubbing against the pulse generator, reducing damage caused by friction. It also facilitates quick and easy storage of the electrode leads and effectively reduces the size of the pouch, making it easier to use and more aesthetically pleasing. This solves a series of issues associated with manually coiling electrode leads, such as the disordered and time-consuming process, pouch bulges, and increased infection.

[0038] In this embodiment, the wire take-up portion 10 is a split structure consisting of a body 11 and an end cap 12. This facilitates the body 11 and end cap 12 forming a box-like structure, allowing for integration of a battery and circuit board. Furthermore, it facilitates assembly with the rotating portion 20. For example, after removing the end cap 12, the rotating portion 20 can be placed over the outer circumference of the body 11, and then the end cap 12 is installed. The end cap 12 and the outer edge 13 clamp the rotating portion 20, thereby achieving installation and positioning of the rotating portion 20. Specifically, a portion of the rotating portion 20 is positioned within the wire take-up groove 15 and is axially positioned by the two axial sidewalls of the wire take-up groove 15 (the first sidewall 151 and the second sidewall 152 of the wire take-up groove 15 in FIG2 ). Furthermore, an annular track can be provided on the end cap 12 and / or the outer edge 13. The rotating portion 20 cooperates with the annular track and guides the rotational direction of the rotating portion 20, thereby achieving circumferential and radial positioning of the rotating portion 20.

[0039] In other alternative embodiments, the take-up portion 10 may also be configured as an integrated structure, and the rotating portion 20 may be directly sleeved on the take-up portion 10 and form a single-degree-of-freedom rotational cooperation relationship with the take-up portion 10 .

[0040] In this embodiment, the outer contour of the wire take-up portion 10 is set to be cylindrical, and the wire take-up groove 15 is provided on the outer circumferential surface of the wire take-up portion 10. In other alternative embodiments, the wire take-up groove 15 can also be provided at one axial end of the wire take-up portion 10, and correspondingly, the rotating portion 20 can also be rotatably mounted on one axial end of the wire take-up portion 10.

[0041] In this embodiment, the wire take-up groove 15 is configured as a circular ring. In other alternative embodiments, the wire take-up groove 15 can also be configured as an arc, such as a semi-annular ring, a 3 / 4 circular ring, an elliptical arc, or an arc groove of other shapes.

[0042] In this embodiment, the outer contour of the wire take-up portion 10 is cylindrical, and the wire take-up groove 15 is a circular arc-shaped groove coaxial with the wire take-up portion 10, that is, the groove depth of the wire take-up groove 15 is constant. In other alternative embodiments, the wire take-up groove 15 can also be an elliptical ring or a special-shaped ring extending along the outer circumference of the wire take-up portion 10, in which case the groove depth of the wire take-up groove 15 is variable. The specific shape of the wire take-up groove 15 can be adjusted based on actual usage requirements.

[0043] In this embodiment, the outer contour of the take-up unit 10 is cylindrical. In other alternative embodiments, the entire outer contour of the take-up unit 10 can also be a rectangular parallelepiped or a special-shaped structure. In this case, the take-up groove 15 can be provided on one end surface of the take-up unit 10, and the corresponding rotating portion 20 can also be rotatably provided on this end. The outer contour shape of the take-up unit 10 and the location of the take-up groove 15 can be adjusted based on actual usage requirements.

[0044] Furthermore, a guide surface 23 is provided on the outer circumferential surface of the rotating portion 20 , and the guide surface 23 is located on at least one side of the second wire hole 21 along the circumferential direction thereof.

[0045] The guide surface 23 may be an inclined surface or a curved surface structure, which is mainly used to guide the electrode wire into or out of the wire-receiving groove 15 during the process of releasing or retrieving the wire, and to prevent the electrode wire from being scratched.

[0046] Please refer to Figures 1 and 5. In this embodiment, a guide surface 23 is provided on one side of the second wire hole 21 in a counterclockwise direction along its circumference. In this embodiment, when the rotating part 20 rotates counterclockwise, the electrode wire is screwed into the wire take-up groove 15. Here, the direction in which the rotating part 20 rotates counterclockwise is referred to as the first direction. The guide surface 23 is tilted from the outside of the second wire hole 21 to the inside against the first direction. Here, the inside of the second wire hole 21 refers to the side close to the wire take-up groove 15, and the outside of the first wire hole 21 refers to the side away from the wire take-up groove 15. Please continue to refer to Figures 1 and 5. When the rotating part 20 rotates counterclockwise, the inner side of the electrode wire fits against the guide surface 23 and enters the wire take-up groove 15; when the rotating part 20 rotates clockwise, the guide surface 23 presses against the inner side of the electrode wire, forcing the electrode wire to be screwed out of the wire take-up groove 15.

[0047] In other alternative embodiments, guide surfaces 23 may be provided on both sides of the second wire hole 21 along its circumference. For example, the existing guide surfaces 23 may be retained, and a guide surface may be added to the inner wall of the second wire hole 21 on the clockwise side along its circumference. Similarly, the guide surface may be inclined from the outside of the second wire hole to the inside, counterclockwise to the first direction. Thus, when the rotating portion 20 rotates counterclockwise, the newly added guide surface presses against the outside of the electrode wire, causing it to be screwed into the wire take-up groove 15.

[0048] Further, please refer to Figures 1 and 2. The interior of the main body 11 has an installation cavity, and the installation cavity extends to the first end of the main body 11 (the upper end of the main body 11 in Figures 1 and 2). That is, in Figures 1 and 2, the main body 11 is a hollow structure with an open upper end and a closed lower end. When the end cover 12 is arranged at the first end of the main body 11 (the upper end of the main body 11 in Figures 1 and 2), the installation cavity is closed. The installation cavity is provided to install devices such as batteries and circuit boards to assemble a pulse generator. The pulse generator winding device serves as the outer shell structure of the pulse generator. This makes the structure of the pulse generator more integrated and more compact.

[0049] The electrode wire needs to be electrically connected to the circuit board through an electrical connector. The function of the first wire hole 14 will also change depending on the assembly method of the electrical connector and the body 11.

[0050] In this embodiment, the electrical connector is integrally formed with the body 11 . The first wire hole 14 can serve as a part of the electrical connector. One end of the electrode wire is located in the first wire hole 14 and is electrically connected to the electronic component of the electrical connector.

[0051] Alternatively, the electrical connector can be independently mounted within the mounting cavity. In this case, the first wire hole 14 extends through the mounting cavity, serving as a threading hole. One end of the electrode wire passes through the first wire hole 14 into the mounting cavity to electrically connect with the electronic components of the electrical connector. Furthermore, to enhance the waterproof performance of the pulse generator wire take-up device, a sealing structure can be provided between the first wire hole 14 and the electrical connector to prevent external moisture from entering the mounting cavity.

[0052] Continuing with Figures 1 and 5 , the outer periphery of the rotating portion 20 is provided with an anti-slip structure. The outer periphery of the rotating portion 20 is provided with a plurality of ridges 25 extending axially. The ridges 25 can be formed by stamping or injection molding. The ridges 25 are evenly spaced along the circumference, and grooves are formed between adjacent ridges 25. The ridges 25 form an anti-slip structure to facilitate manual rotation of the rotating portion 20.

[0053] In other alternative embodiments, the anti-slip structure on the rotating part 20 may be an anti-slip groove or a small protrusion formed by frosting.

[0054] Please continue to refer to Figures 1 and 3. The end cap 12 is provided with an anti-slip structure. The end cap 12 is provided with a radial anti-slip groove 18 at one axial end away from the body 11. A convex structure is formed between adjacent anti-slip grooves 18. The anti-slip structure formed by the anti-slip grooves 18 facilitates the fixing of the body 11 after pressing the end cap 12, thereby facilitating the rotation of the rotating part 20 relative to the body 11. The lower end of the body 11 of the pulse generator winding device can be fixed to the user by means of gluing or the like. When the rotating part 20 needs to be rotated, the end cap 12 can be pressed by fingers or palms so that the end cap 12 and the body 11 are fixed to the human body. Then, the rotating part 20 can be rotated with two fingers to release or retract the electrode wire.

[0055] Alternatively, when the pulse generator wire collection device is placed in the pouch and the electrode lead needs to be adjusted, two fingers axially clamp the end cap 12 and the body 11, and then use the other hand to hold the undulating rotating part 20 to rotate it. The anti-slip structure on the rotating part 20 and the end cap 12 facilitates single-handed operation to release or retract the electrode lead.

[0056] In other alternative embodiments, the anti-slip structure on the end cover 12 may be an anti-slip groove or a small protrusion formed by frosting.

[0057] As shown in Figures 3 and 4 , the end cap 12 is disc-shaped with an outwardly arched center. Three connecting posts 17 are provided on the inner side of the end cap 12. The first end of the corresponding body 11 (the upper end of the body 11 in Figures 1 and 2 ) is provided with a connecting hole (not shown). The end cap 12 is mounted on the first end of the body 11, and the connecting posts 17 are inserted into the connecting holes. The connecting posts 17 can be fixed in the connecting holes by an interference fit or adhesive bonding, thereby achieving the connection between the end cap 12 and the body 11.

[0058] In other alternative embodiments, a snap-fit ​​structure may be provided on the inner wall of the end cap 12, and a snap-fit ​​hole adapted to the snap-fit ​​structure may be provided on the corresponding body 11, thereby achieving a detachable snap-fit ​​connection between the end cap 12 and the body 11. Alternatively, the end cap 12 may be connected to the body 11 by screws, welding, or the like, which will not be described in detail here.

[0059] Furthermore, a first stop-rotation structure 16 is provided on the take-up part 10, and a second stop-rotation structure 22 is provided on the rotating part 20. The first stop-rotation structure 16 is located on the rotation path of the second stop-rotation structure 22 when the rotating part 20 rotates, so as to limit the rotation angle of the rotating part 20.

[0060] 4 and 5 , the first anti-rotation structure 16 is an arc-shaped groove extending around the rotation center axis of the rotating portion 20 . The first anti-rotation structure 16 is disposed on the inner wall of the end cover 12 .

[0061] The second anti-rotation structure 22 is a cylindrical protrusion, and the second anti-rotation structure 22 is provided on the rotating part 20. As shown in Figure 5, the upper end of the rotating part 20 has an annular inner edge 24 extending radially outward, and the second anti-rotation structure 22 is provided on the inner edge 24. The provision of the inner edge 24, on the one hand, provides a mounting position for the second anti-rotation structure 22, and on the other hand, when the end cover 12 is provided on the main body 11, the end cover 12 axially fits with the inner edge 24 to axially limit the rotating part 20. The protrusion is located in the arc-shaped groove. By setting the length of the arc-shaped groove, the movement stroke of the protrusion in the arc-shaped groove can be adjusted, thereby adjusting the rotation angle of the rotating part 20 relative to the main body 11. In addition, the cooperation between the protrusion and the arc-shaped groove also plays a guiding role for the rotating part 20, allowing the rotating part 20 to rotate along a predetermined track. At the same time, it also plays a positioning role, which can prevent the rotating part 20 from moving radially, thereby playing a role in radial positioning of the rotating part 20.

[0062] By disposing the first anti-rotation structure 16 and the second anti-rotation structure 22, the rotation angle of the rotating portion 20 can be accurately controlled, thereby controlling the winding length of the electrode wire to avoid winding the wire too tightly and pulling the electrode wire.

[0063] In other alternative embodiments, when the wire take-up groove 15 is configured as an arc-shaped groove, the wire take-up groove 15 itself can also serve as the first anti-rotation structure 16 .

[0064] In other alternative embodiments, the second anti-rotation structure 22 can be configured as a protrusion of other shapes, such as a rectangular protrusion structure.

[0065] In other alternative embodiments, the first anti-rotation structure 16 can be set as a protrusion structure, and the second anti-rotation structure 22 can be set as an arc-shaped groove structure, that is, the positions of the protrusion and the arc-shaped groove are interchangeable.

[0066] In other alternative embodiments, the first stop structure 16 and the second stop structure 22 can also be set to other structures. For example, the first stop structure 16 in Figure 4 is replaced by two blocking blocks, and the two blocking blocks are located on the rotation path of the second stop structure 22. Then, the second stop structure 22 can only rotate between the two blocking blocks to achieve the purpose of limiting the rotation angle of the rotating part 20.

[0067] In addition, this embodiment also provides a pulse generating system, which is a temporary pacing system, including an electrode wire and a pulse generator. The pulse generator includes the pulse generator winding device described above. The pulse generator also includes a circuit board and a battery, etc. The battery supplies power to the circuit board, and the circuit board and the battery are arranged in the pulse generator winding device. One end of the electrode wire is located in the winding part 10 and is connected to the circuit board through an electrical connector, and the other end of the electrode wire passes through the first wire hole 14, the winding groove 15 and the second wire hole 21 in sequence to the outside of the pulse generator winding device for collecting user body signals, such as collecting heart rate. The electrode wire is also used to transmit the collected signal to the circuit board. The installation method and connection method of the circuit board and the battery are both existing technologies, and the other structures of the pulse generating system are consistent with the existing structure and will not be repeated here.

[0068] In addition, the above-mentioned pulse generating system can also be a brain pacemaker system or a cardiac pacemaker system.

[0069] The above description is only a description of the preferred embodiments of the present invention and is not intended to limit the scope of the present invention. Any changes and modifications made by ordinary technicians in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
