Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, and in particular to a cardiac pacemaker fixation component. Background Technology
[0002] A cardiac pacemaker delivers electrical pulses powered by a battery through a pulse generator. These pulses are conducted through electrodes to stimulate the myocardium in contact with the electrodes, causing the heart to beat and contract, thereby treating cardiac dysfunction caused by certain arrhythmias.
[0003] After surgery, the pacemaker needs to be fixed. The current method involves making an incision in the skin with a scalpel and suturing the pacemaker inside the skin for fixation. This method can ensure the stability of the pacemaker, but it has certain drawbacks. On the one hand, it increases the surgical incision area and prolongs the patient's recovery time. On the other hand, when the pacemaker needs to be replaced, it is necessary to make another incision in the skin to remove it. Also, if the pacemaker is accidentally damaged by external impact, it cannot be replaced in time. Therefore, a pacemaker fixation component is needed. Utility Model Content
[0004] The purpose of this invention is to provide a cardiac pacemaker fixation component to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a pacemaker fixation assembly, including a placement box, a first elastic band fixedly connected to one side of the placement box, a second elastic band fixedly connected to the other side of the placement box, a third elastic band fixedly connected to the surfaces of both the first and second elastic bands, an arc-shaped surface on one side of the inner wall of the placement box, and a vertical surface on the other side of the inner wall of the placement box, for fitting snugly against the surface of the pacemaker's outer shell, and a positioning and anti-detachment mechanism provided on the surface of the placement box;
[0006] The positioning and anti-detachment mechanism includes an installation groove formed on the surface of the placement box. A telescopic rod is fixedly connected to the inner wall of the installation groove. A moving plate is fixedly connected to one end of the telescopic rod. A limit slider is fixedly connected to the upper surface of the moving plate. A spring is sleeved on the surface of the telescopic rod. One end of the spring is fixedly connected to the inner wall of the installation groove, and the other end of the spring is fixedly connected to the surface of the moving plate. A contact arc groove is formed on the lower surface of the limit slider for fitting snugly against the surface of the pacemaker's outer shell.
[0007] Preferably, a flexible plastic plate is fixedly connected to the inner wall of the first elastic band, and the surface of the flexible plastic plate is provided with a plurality of slotted holes, and a sleeve is fixedly connected to the inner wall of the second elastic band.
[0008] Preferably, a T-shaped shaft is rotatably connected to the inner wall of the sleeve, one end of the T-shaped shaft is fixedly connected to a plate, a torsion spring is sleeved on the surface of the T-shaped shaft, one end of the torsion spring is fixedly connected to the inner wall of the sleeve, and the other end of the torsion spring is fixedly connected to the surface of the T-shaped shaft.

In this utility model, the arc-shaped surface and the vertical surface are used to fit and conform to the surface of the product shell of the heart pacemaker, and the contact arc groove is used to fit and conform to the surface of the product shell of the heart pacemaker. The advantage of doing so is that the heart pacemaker placed in the placement box is stabilized by limiting it with two surfaces, and the heart pacemaker can also be quickly replaced and disassembled.
[0014] 2. In this utility model, when the pacemaker is worn, it is worn on the patient's body through the first elastic band, the second elastic band and the third elastic band. The friction plate squeezes the surface of the third elastic band to generate friction and limit the third elastic band.

A contact arc groove 8 is formed on the lower surface of the limit slider 5 for fitting and conforming to the surface of the product shell of the heart pacemaker.
[0025] With the above structure, a placement box 1 is provided to install the appropriate pacemaker product. The placement box 1 is fixed in place by the first elastic band 2, the second elastic band 3 and the third elastic band 4. The arc-shaped surface 6 and the vertical surface 7 are provided to fit snugly against the surface of the pacemaker product shell.

[0026] Preferably, a flexible plastic plate 17 is fixedly connected to the inner wall of the first elastic band 2, and a plurality of slotted holes 21 are opened on the surface of the flexible plastic plate 17. A sleeve 19 is fixedly connected to the inner wall of the second elastic band 3.
[0027] By setting a flexible plastic plate 17, it can bend and deform under force, better fit the patient's skin, and not affect the patient's limb movement. By setting a slotted hole 21, the installation of the slotted plate 22 is avoided.
[0028] Preferably, a T-shaped shaft 18 is rotatably connected to the inner wall of the sleeve 19, one end of the T-shaped shaft 18 is fixedly connected to a plate 22, a torsion spring 20 is sleeved on the surface of the T-shaped shaft 18, one end of the torsion spring 20 is fixedly connected to the inner wall of the sleeve 19, and the other end of the torsion spring 20 is fixedly connected to the surface of the T-shaped shaft 18.
[0029] By setting a T-shaped shaft 18 and rotating the T-shaped shaft 18, the installation angle of the straight plate 22 is changed. By setting a torsion spring 20, the T-shaped shaft 18 and the straight plate 22 are rotated and reset, ensuring that the straight plate 22 is in contact with the surface of the tough plastic plate 17 to form an inverted buckle.
[0030] Preferably, a U-shaped sleeve 13 is fixedly connected to the surface of the first elastic band 2, a friction plate 14 is slidably connected to the inner wall of the U-shaped sleeve 13, and a screw 15 is threadedly connected to the inner wall of the U-shaped sleeve 13, with one end of the screw 15 rotatably connected to the surface of the friction plate 14.
[0031] By setting the screw 15, the operator can rotate the screw 15 to change the position of the friction plate 14, thereby squeezing the surface of the third elastic band 4 and keeping the third elastic band 4 stably positioned on the shoulder.
[0032] Preferably, a breathable adhesive tape 16 is fixedly connected to one side of the box 1.
[0033] When the placement box 1 needs to be re-secured by setting the breathable adhesive tape 16, the breathable adhesive tape 16 can be torn off and the placement box 1 can be fixed to the patient's skin surface by adhesive.
[0034] Preferably, the inner wall of the placement box 1 is provided with a plurality of first ventilation holes 24, and the surface of the first elastic band 2 is provided with a plurality of second ventilation holes 12.
[0035] By providing the first vent 24, heat dissipation is ensured when the pacemaker installed in the placement box 1 is working, and by providing the second vent 12, breathability and comfort are ensured when wearing it.
[0036] The working principle of this utility model is as follows: A pacemaker fixation component, in use, inserts the two catheters of the pacemaker into the correct position in the heart, sutures the surgical wound, and then installs the pacemaker in the placement box 1. It is then worn on the patient's body via the first elastic band 2, the second elastic band 3, and the third elastic band 4. During pacemaker installation, the limiting slider 5 is pushed to place the pacemaker in the placement box 1. Releasing the limiting slider 5 allows it to reset under the action of the spring 10, so that the surface of the contact groove 8 contacts the surface of the pacemaker. The pacemaker is installed in the placement box 1 in an inverted position, maintaining stable pressure. When wearing the first elastic band 2 and the second elastic band 3, the T-shaped shaft 18 is rotated to insert the flat plate 22 into the flat hole 21. At this time, the torsion spring 20 is taut. After the plate 22 is inserted into the hole 21, the T-shaped shaft 18 is released, allowing the plate 22 to return to its original position under the action of the torsion spring 20. The surface of the plate 22 contacts the surface of the tough plastic plate 17, forming an inverted buckle through the plate 22, ensuring that the first elastic band 2 and the second elastic band 3 will not separate. Rotating the screw 15 drives the friction plate 14 to squeeze the surface of the third elastic band 4 to generate friction, limiting the third elastic band 4. Before wearing the placement box 1, the protective film of the breathable adhesive 16 can be peeled off and the breathable adhesive 16 can be adhered to the patient's skin surface. With the above structure, the increase of surgical wound caused by suturing the pacemaker under the skin is prevented. At the same time, when the pacemaker fails or is damaged, it can be quickly replaced to ensure the safety of the user.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
