Abstract
Description
Technical Field
[0001] This invention relates to the field of cardiovascular detection technology, and more specifically, to a cardiovascular intubation imaging aid device and its application method. Background Technology
[0002] During cardiac surgery or examinations, doctors often need to hold a laryngoscope assembly for inspection. Existing technology provides a CN112754412A – a cardiovascular intubation imaging-assisted detection device. To avoid hand tremors caused by prolonged manipulation of the laryngoscope assembly inside the patient, which could lead to swaying and collisions with pathogens, affecting both observation accuracy and patient health, this solution uses a clamping and fixing method to prevent hand tremors. While this method solves the problem of tremor prevention after the laryngoscope assembly is in place, it severely restricts its movement. Furthermore, placing and removing the laryngoscope assembly is difficult, and the possible positions and angles for fixing it are very limited, especially at oblique angles. The clamp itself also hinders movement. A more flexible tremor prevention method is needed. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to provide a cardiovascular intubation imaging-assisted device and application method, in view of the above-mentioned defects of the prior art.
[0004] The technical solution adopted by this invention to solve its technical problem is:
[0005] A cardiovascular intubation imaging-assisted device is constructed, comprising a detection host and a laryngoscope assembly connected to the detection host, and a mounting base for mounting the detection host. The mounting base is provided with a top bracket, and the top bracket is provided with a clutch connector and a three-phase motion mechanism that can be manually operated and moved along the X, Y, and Z axes. A spherical stainless steel ball is fixedly provided at the tail end of the operating handle of the laryngoscope assembly. The clutch connector includes a base fixedly connected to the movable end of the three-phase motion mechanism. A hemispherical cover that cooperates with the spherical stainless steel ball is connected to the base via a universal joint. Multiple electromagnets that attract the spherical stainless steel ball and control switches that control the operation of the multiple electromagnets are arranged in a ring on the hemispherical cover. Multiple oblique positioning rods and multiple oblique through holes corresponding to the positioning rods are arranged in a ring on the base. The lower end of the positioning rod is provided with an iron piece that fits against the outer surface of the hemispherical cover.
[0006] The cardiovascular intubation imaging-assisted device of the present invention includes a three-phase motion mechanism comprising a Z-axis assembly and an XY-axis assembly disposed on the top support; the Z-axis assembly is a longitudinal damping telescopic rod connected to the movable end of the XY-axis assembly, and the base is connected to the lower end of the damping telescopic rod.
[0007] The cardiovascular intubation imaging-assisted device of the present invention includes an XY-axis assembly comprising a first lead screw arranged along the X-axis and a second lead screw arranged along the Y-axis; the first lead screw is mounted on the top support, and the movable end of the first lead screw is provided with a strip-shaped mounting plate for mounting the second lead screw; the second lead screw is mounted on the lower surface of the mounting plate, and the movable end of the second lead screw is connected to the damping telescopic rod.
[0008] The cardiovascular intubation imaging-assisted device of the present invention includes a first damping shaft on the top support that provides rotational damping force to the lead screw shaft of the first lead screw; and a second damping shaft on the mounting plate that provides rotational damping force to the lead screw shaft of the second lead screw.
[0009] The cardiovascular intubation imaging-assisted device of the present invention includes a top support comprising a strip plate for mounting the first lead screw and a longitudinal support rod connected to one end of the strip plate, wherein the longitudinal support rod is fixedly connected to the mounting base.
[0010] The cardiovascular intubation imaging aid device of the present invention includes a wire-passing hole inside the strip plate and a wire-passing sleeve on the side of the base. Power lines for supplying power to the multiple electromagnets pass through the wire-passing sleeve and the wire-passing hole in sequence and are electrically connected to the detection host.
[0011] A method for applying a cardiovascular intubation imaging-assisted device, which is used in the cardiovascular intubation imaging-assisted device described above, is implemented as follows:
[0012] The operator holds the operating handle of the laryngoscope assembly with their right hand. When the laryngoscope is moved to the position where it needs to be fixed for observation, the operator raises their left hand to hold the hemispherical cover and pulls it to move and cover the spherical stainless steel bead. Then, the operator closes the control switch, which energizes multiple electromagnets. One end of each electromagnet attracts the spherical stainless steel bead for fixation, and the other end of each electromagnet attracts the positioning rod to fix the current tilt angle of the hemispherical cover, thus completing the fixation of the operating handle position of the laryngoscope assembly.
[0013] When the laryngoscope assembly needs to be moved, hold the operating handle of the laryngoscope assembly with your right hand and turn on the control switch with your left hand. The multiple electromagnets will lose power and release their attraction, allowing you to remove the laryngoscope assembly.
[0014] The beneficial effects of this invention are as follows: The operator holds the operating handle of the laryngoscope assembly with their right hand. When moving it to the desired fixed observation position, the operator lifts and grasps the hemispherical cover with their left hand, pulling it to cover the spherical stainless steel bead. Then, the control switch is closed, energizing multiple electromagnets. One end of each electromagnet attracts and fixes the spherical stainless steel bead, while the other end attracts the positioning rod, fixing the current tilt angle of the hemispherical cover and thus fixing the position of the operating handle of the laryngoscope assembly. When the laryngoscope assembly needs to be moved, the operator holds the operating handle with their right hand and opens the control switch with their left hand. The multiple electromagnets are de-energized and released, allowing the laryngoscope assembly to be removed. The support does not obstruct the use of the laryngoscope assembly and solves the problem of fixing the position of the laryngoscope assembly in an oblique position, which is impossible with existing equipment. This significantly improves operational flexibility and further addresses the issue of hand tremors. Attached Figure Description

The drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0017] Figure 2 This is an enlarged schematic diagram of the clutch connector of the cardiovascular cannulation imaging aid device according to a preferred embodiment of the present invention. Detailed Implementation
[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.
[0019] The cardiovascular intubation imaging-assisted device of a preferred embodiment of the present invention, such as Figure 1 As shown, see also Figure 2The device includes a detection host 1 and a laryngoscope assembly 2 connected to the detection host 1, and a mounting base 3 for mounting the detection host 1. The mounting base 3 has a top bracket 4, and the top bracket 4 has a clutch connector 5 and a three-phase motion mechanism 6 that can be manually operated and moved along the X, Y, and Z axes. A spherical stainless steel ball 7 (preferably hollow inside, and multiple slots can be provided on the surface of the ball to reduce weight) is fixedly mounted on the end of the operating handle of the laryngoscope assembly 2. The clutch connector 5 includes a base 50 fixedly connected to the movable end of the three-phase motion mechanism 6. A hemispherical cover 52 that cooperates with the spherical stainless steel ball 7 is connected to the base 50 via a universal joint 51. Multiple electromagnets 53 for attracting the spherical stainless steel balls are arranged in a ring on the hemispherical cover 52, and multiple electromagnets 53 for controlling the movement of the spherical stainless steel balls are also present. The electromagnet operates with a control switch 54; the base 50 has multiple oblique (preferably 30-60 degrees) positioning rods 55 arranged in a ring on it (the number and distribution of the positioning rods need to be relatively dense to ensure that at least two positioning rods distributed on different sides of the base are attracted each time they are attracted, so that the hemispherical cover 52 and at least two positioning rods form a single V-shaped or multiple V-shaped structure, thereby fixing the deflection angle of the hemispherical cover; when the electromagnet releases the attraction of the positioning rods, the lower end of the positioning rod abuts against the hemispherical cover and can move freely in the oblique through hole 56 with the squeezing and pushing force of the hemispherical cover) and multiple oblique through holes 56 corresponding one-to-one with the positioning rods 55; the lower end of the positioning rod 55 is provided with an iron piece 57 that fits against the outer surface of the hemispherical cover 52.
[0020] The operator holds the operating handle of the laryngoscope assembly 2 with their right hand. When moving it to the position where fixed observation is needed, the operator raises their left hand to grasp the hemispherical cover 52 and pulls it to move it and cover the spherical stainless steel bead 7 (at this time, if the operating handle is angled, the hemispherical cover will also be deflected at a certain angle to cover the spherical stainless steel bead). Then, the operator closes the control switch 54, which energizes multiple electromagnets 53. One end of each electromagnet 53 attracts the spherical stainless steel bead 7 for fixation, while the other end of each electromagnet 53 attracts the corresponding... The attached positioning rod 55 fixes the current tilt angle of the hemispherical cover 52, thus fixing the position of the operating handle of the laryngoscope assembly 2. When it is necessary to move the laryngoscope assembly 2, hold the operating handle of the laryngoscope assembly 2 with your right hand and turn on the control switch 54 with your left hand. The multiple electromagnets 53 will be de-energized and released from their attraction, allowing you to remove the operating handle of the laryngoscope assembly. The bracket will not obstruct the use and operation of the laryngoscope assembly, and at the same time, it can solve the problem of fixing the position of the laryngoscope assembly in an oblique state, which is impossible with existing equipment. This greatly improves the flexibility of operation and further solves the problem of hand tremors.
[0021] Preferably, the three-phase motion mechanism 6 adopts a damped non-active drive structure, wherein the Z-axis assembly is a longitudinal damping telescopic rod 60, and the XY-axis assembly consists of a first lead screw 61 arranged along the X-axis and a second lead screw 62 arranged along the Y-axis; the first lead screw 61 is mounted on the top bracket 4, and the movable end of the first lead screw 61 is provided with a strip-shaped mounting plate 63 for mounting the second lead screw 62; the second lead screw 62 is mounted on the lower surface of the mounting plate 63, and the movable end of the second lead screw 62 is connected to the damping telescopic rod 60; the top bracket 4 is provided with a first damping shaft 40 that provides rotational damping force to the lead screw shaft of the first lead screw 61; the mounting plate is provided with a second damping shaft that provides rotational damping force to the lead screw shaft of the second lead screw 62;
[0022] During operation, the operator manually drives the hemispherical cover 52 to move, thereby causing the damping telescopic rod 60 to extend, retract, and laterally move. The lateral movement of the damping telescopic rod 60 will cause the first lead screw and the second lead screw to move in the corresponding direction, and the corresponding damping shaft will provide the positioning force after the movement. The magnitude of the damping force can be selected or adjusted according to actual needs. All components constituting the three-phase motion mechanism can use existing components. Among them, the first damping shaft 40 and the second damping shaft can adopt a structure consisting of an inner shaft and an outer damping sleeve. During installation, one of the inner shaft and the outer damping sleeve is fixed coaxially with the corresponding lead screw shaft, and the other is fixed with the top bracket 4.
[0023] Preferably, the top support 4 consists of a strip plate 42 for mounting the first lead screw and a longitudinal support rod 43 connected to one end of the strip plate 42. The longitudinal support rod 43 is fixedly connected to the mounting base 3. The strip plate 42 has a wire hole inside, and the base 50 has a wire sleeve 58 on its side. The power cords that supply power to the multiple electromagnets 53 pass through the wire sleeve 58 and the wire hole in sequence and are electrically connected to the detection host 1. Preferably, the power cords need to have some slack to avoid affecting the movement adjustment of the hemispherical cover.
[0024] A method for applying a cardiovascular intubation imaging-assisted device, which is used in the cardiovascular intubation imaging-assisted device described above, is implemented as follows:
[0025] The operator holds the operating handle of the laryngoscope assembly with their right hand. When the laryngoscope is moved to the position where it needs to be fixed for observation, the operator raises their left hand to hold the hemispherical cover and pulls it to move and cover the spherical stainless steel bead. Then, the operator closes the control switch, which energizes multiple electromagnets. One end of the multiple electromagnets attracts the spherical stainless steel bead for fixation, and the other end of the multiple electromagnets attracts the positioning rod accordingly, fixing the current tilt angle of the hemispherical cover and completing the fixation of the laryngoscope assembly.
[0026] When the laryngoscope assembly needs to be moved, hold the laryngoscope assembly with your right hand and turn on the control switch with your left hand. The multiple electromagnets will lose power and release their attraction, and the laryngoscope assembly can be removed.
[0027] By applying the method of this application, the support will not obstruct the use and operation of the laryngoscope assembly, and at the same time, it can solve the problem of fixing the position of the laryngoscope assembly in an oblique state, which is impossible with existing equipment, greatly improving the flexibility of operation and further solving the problem of hand tremors.
[0028] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
