Description

Technical Field

[0001] The invention relates to an ultrasonic detection device, in particular to a device for assisting esophagus ultrasonic detection. Background Art

[0002] Esophageal ultrasound testing equipment plays a vital role in heart testing. The doctor inserts the ultrasound probe into the patient's esophagus and adjusts the position and angle of the probe so that it can accurately point to different parts of the heart. The device then emits ultrasound waves and receives the reflected sound wave signals, which are processed and converted into visual images displayed on the screen. Doctors can observe these images in real time to understand the structure, function and blood flow of the heart. This device provides doctors with clear, high-resolution images of the heart's interior through the special path of the esophagus, especially the structure on the back of the heart, which is difficult to reach with traditional transthoracic ultrasound.

[0003] However, existing esophageal ultrasound detection equipment has certain challenges in operation. Since the equipment needs to control the probe to penetrate the esophagus and adjust the direction and angle of the probe at the same time, medical staff usually need to hold the control handle with one hand to adjust the angle and position of the probe, and use the other hand to control the probe to penetrate the esophagus. This two-handed operation method requires high operating skills of medical staff, which not only increases the complexity of the operation, but also may affect the accuracy and safety of the test.

[0004] To solve this problem, it would be very helpful to design a device that can place the control handle. Summary of the invention

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0030] Embodiment: A device for assisting esophageal ultrasound detection, such as Figure 1-Figure 7 As shown, it includes a base 1, the base 1 is equipped with a self-locking moving wheel 24, the main bracket 2 is fixed to the base 1, the extension frame 3 is fixed to the upper end of the main bracket 2, and a hanging rod 25 is arranged on the top of the extension frame 3 for hanging the probe, the rotating seat 4 is rotatably connected to the lower end of the extension frame 3, and the side of the rotating seat 4 is connected to the placement frame 5, and also includes a rotating mechanism and an air pressure pump 11 for driving the placement frame 5 to lift. The rotating mechanism consists of a crawler track 6, an articulated rod 7, a rotating shaft 8, a first gear 9 and an inner gear ring 10. The crawler track 6 is rotatably connected in the base 1, and the rotating shaft 8 is rotatably connected in the main bracket 2. The bottom of the rotating shaft 8 is fixed with an articulated rod 7, and the articulated rod 7 can be retracted. The end of the articulated rod 7 is rotatably connected to an articulated seat, and the articulated seat is connected to the crawler track. 6, a first gear 9 is fixedly connected to the upper end of the rotating shaft 8, and the first gear 9 is meshed with the inner gear ring 10 fixedly connected to the bottom of the rotating seat 4. The air pressure pump 11 is arranged in the rotating shaft 8, and the pressing head 1101 of the air pressure pump 11 is partially located in the base 1. The extension frame 3 is hollow and the side wall is provided with an axial guide groove 301. The lifting head 1102 is limitedly slid in the guide groove 301, and the lifting head 1102 is rotatably connected to the rotating seat 4 by a key connection. The air pressure pump 11 can be pressurized by high-frequency stepping on the pressing head 1101, and the lifting head 1102 moves upward. Continuous stepping on the pressing head 1101 can relieve the pressure on the air pressure pump 11, and the lifting head 1102 moves downward under the action of gravity.

[0031] like Figure 6 and Figure 7As shown, a clamping mechanism is arranged in the placement frame 5, and the clamping mechanism consists of a bearing block 12, a wedge push rod 13, a clamping rod 14 and a connecting rod 15. The bearing block 12 slides vertically and penetrates the middle part of the placement frame 5. A spring is connected between the bearing block 12 and the placement frame 5. The end face of the bearing block 12 is set to a concave shape, and the concave part is provided with a rubber sheet, which can not only accurately and stably place the control handle, but also the rubber sheet can greatly improve the friction coefficient between the control handle and the bearing block 12, so as to improve the stability of the control handle after placement. The wedge push rod 13 is slidably connected to the bottom surface of the placement frame 5, the bearing block 12 can contact and push the wedge push rod 13, and the clamping rod 14 limits The control handle 12 is placed on the support block 12 and is then moved downwards to push the wedge head push rod 13 toward the two ends of the support block 12. At the same time, the connecting rod 15 on the side of the wedge head push rod 13 will pull the clamping rod 14 to slide in the opposite direction, and the clamping rod 14 will clamp and fix the control handle. A limit contact 16 is arranged on the upper end of the clamping rod 14 and a spring is connected between the two. The limit contact 16 can further clamp and fix the control handle. At this time, the medical staff can operate the control handle without holding the control handle.

[0032] like Figure 6 and Figure 7 As shown, it also includes a locking rod 17, which is slidably connected in the placement frame 5. The locking rod 17 limits and fixes the support block 12. An inclined surface is provided at the end of the locking rod 17. When the support block 12 descends, the inclined surface can be pushed to make the locking rod 17 move horizontally, and then the locking rod 17 limits and fixes the support block 12 under the action of the spring. At this time, the clamping rod 14 and the limit contact 16 fix the control handle. When the fixation needs to be released, the locking rod 17 can be pulled outward. After the locking rod 17 is separated from the support block 12, the support block 12 is reset under the action of the spring, and the clamping rod 14 will also release the limit on the control handle, so that the medical staff can take out the control handle.

[0033] like Figure 8 As shown, it also includes a second gear 18 and a rack 19. The placement rack 5 is rotatably connected to the rotating seat 4. The second gear 18 is fixed to the rotating shaft of the placement rack 5, and the rack 19 is fixed to the extension rack 3. The rack 19 can engage with the second gear 18. The medical staff steps on the pressing head 1101 to make the lifting head 1102 move upward, and the lifting head 1102 drives the rotating seat 4 to move upward. The rack 19 contacts the second gear 18 and drives it to rotate. The tooth length of the rack 19 is set to 1 / 4 of the circumference of the second gear 18. Therefore, the horizontal placement rack 5 will be rotated 90 degrees to a vertical state, and the medical staff can easily place the control handle on the placement rack 5 to achieve the effect of convenient storage.

[0034] like Figure 8-Figure 10As shown, it also includes a locking block 20 and a contact rod 21. The locking block 20 is slidably connected in the rotating seat 4. A slot is provided on the side of the second gear 18. The locking block 20 can be slidably embedded in the slot to fix the second gear 18. The contact rod 21 is fixed to the side of the rack 19. The contact rod 21 can push the locking block 20 to move. Specifically, an inclined surface is provided on the side of the locking block 20, and the inclined surface faces the direction of the second gear 18. In the initial state, the locking block 20 is embedded in the second gear 18. At this time, the second gear 18 is in a locked state, that is, the placement frame 5 is in a locked state. When the rotating seat 4 moves upward, the contact rod 21 can contact and push the locking block 20 to move it in the direction away from the second gear 18, thereby releasing the lock of the second gear 18, and then the rack 19 can drive the second gear 18 to rotate.

[0035] like Figure 1 and Fig.11 As shown, it also includes a holder 22, which is fixedly connected to the extension frame 3. The holder 22 is hollow, and a reed 2201 is provided on the hollow inner wall. A magnetic buckle 2202 is provided at the lower part of the holder 22. The holder 22 can hold medical instruments, such as the main body part of an ultrasonic detection machine or simple instruments, such as a stethoscope, etc. The reed 2201 clamps the medical instrument laterally, and the magnetic buckle 2202 hangs and fixes the medical instrument.

[0036] like Figure 1 and Figure 2 As shown, a correction button 23 is also included, which is arranged in the rotating seat 4. The inner end of the correction button 23 is a retractable sphere, which can be embedded in the guide groove 301. Through this component, medical staff can move the rotating seat 4 to the initial position, and the rack 19 at this position can accurately cooperate with the second gear 18.

[0037] The working principle of the embodiment of the present invention is as follows: the medical staff places the main body part of the ultrasonic detection machine in the card seat 22, and the medical staff places the control handle on the support block 12 and presses it lightly. The support block 12 will move downward and then push the wedge head push rod 13 to move toward the two ends of the placement frame 5. The support block 12 is fixed by the locking rod 17. At the same time, the connecting rod 15 on the side of the wedge head push rod 13 will drive the clamping rod 14 to slide in the opposite direction, and the clamping rod 14 thereby clamps and fixes the control handle. The limit contact 16 arranged on the upper end of the clamping rod 14 can firmly clamp and fix the control handle. The medical staff operates the control handle while the control handle is on the placement frame 5, avoiding the situation that the medical staff holds the control handle for a long time. On the other hand, the probe of the ultrasonic detection machine is inserted into the corresponding part of the patient's esophagus for inspection. During this period, as the inspection angle changes, if the ultrasonic detection machine needs to be rotated, the foot can be gently placed on the track 6 to rub it to make the track 6 rotate, and the track 6 will be driven by the hinge rod 7 When the rotating shaft 8 rotates, the rotating shaft 8 drives the inner gear ring 10 to rotate through the first gear 9, and then drives the rotating seat 4 to rotate, and the placement rack 5 will also rotate accordingly, so as to cooperate with the medical staff's control of the control handle. The medical staff pulls the locking rod 17 to unlock the clamping rod 14, and the control handle can be taken out. The medical staff steps on the pressing head 1101 to pressurize the air pressure pump 11, so that the lifting head 1102 moves upward, and the lifting head 1102 can drive the rotating seat 4 to move up synchronously. After the lifting head 1102 drives the rotating seat 4 to rise to a certain height, the contact rod 21 pushes the locking block 20 that restricts the second rack 19 to unlock it, and then the rack 19 can contact and drive the second gear 18 to rotate, so that the placement rack 5 is rotated from the horizontal use state to the vertical storage state. When the medical staff needs to use it, they can step on the pressing head 1101 to relieve the pressure on the air pressure pump 11, and the placement rack 5 will be rotated and reset from the vertical state to the horizontal state, and the medical staff can also operate the control handle more conveniently.

[0038] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, all equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
