Description

Technical Field

[0001] The invention relates to the technical field of prenatal ultrasonic diagnosis and treatment, in particular to a prenatal diagnosis and examination device for clinical use in obstetrics and gynecology. Background Art

[0002] Prenatal diagnosis refers to the detection and diagnosis of the developmental status of the embryo or fetus, whether it has a disease, etc. before birth. Currently, prenatal diagnosis can help us seize the initiative and choose the appropriate time for intrauterine treatment for treatable diseases, while making informed choices for untreatable diseases.

[0003] Gynecological ultrasound examination, also known as gynecological ultrasound or gynecological ultrasound, is a common medical examination and treatment method used to evaluate the female reproductive system, including the uterus, ovaries and pelvic organs. This non-invasive examination method provides detailed images by using ultrasound technology to help doctors diagnose and monitor various gynecological diseases, as well as assist in women's reproductive health and pregnancy management. As disclosed in Chinese patent CN111617394B, a new type of multi-purpose ultrasound therapeutic device for obstetrics and gynecology is suitable for ultrasound treatment and examination in obstetrics and gynecology. The rotation of the horizontal axis drives the first cylinder and the second cylinder to rotate simultaneously in different directions, so that the rotation directions of the balls corresponding to the first cylinder and the second cylinder are different. Not only can the essential oil or developer be evenly applied to the part that needs treatment or detection, but also the ultrasound probe can be used for detection or treatment.

[0004] However, during the ultrasound examination, the pregnant woman usually needs to lie on the examination bed, and the doctor needs to apply coupling agent to the surface of the ultrasound probe. Then, the doctor places the ultrasound probe on the pregnant woman's abdomen with one hand and moves it, and uses the other hand to operate the imaging device and recording device to record the ultrasound image. After finding the required part, the probe will stay there to monitor the patient's internal organs. However, during the long-term moving and searching process, the hands lack support and are prone to fatigue. In addition, the ultrasound probe is not fixed, which makes it easy for the position to deviate during the staying process. At the same time, the ups and downs of the pregnant woman's abdomen and the adjustment of her body position can easily affect the accuracy of the stay, thereby affecting the accuracy of prenatal diagnosis and treatment.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] For example, see Figure 1-10 , the present invention provides a technical solution: a prenatal diagnosis and examination device for clinical use in obstetrics and gynecology, comprising an ultrasonic probe 1 and an examination bed body 21;

[0038] Then, an adsorption component is arranged on the top of the ultrasonic probe 1 , and a quick fixing assembly 9 is arranged on the top of the shell 3 . A support ring 20 is fixedly installed on one side of the examination bed body 21 , and a fixing ring 19 is fixedly connected to the outer wall of the shell 3 corresponding to the support ring 20 .

[0039] Furthermore, the adsorption component includes a rubber piston 5 , the top of the guide plate 6 is in a truncated cone shape, and the bottom of the rubber piston 5 fits with the top of the sealing ring 2 .

[0040] The quick fixing assembly 9 includes a fixing rod 901, the bottoms of the two fixing rods 901 are fixedly connected to the top of the housing 3, and then the fixing rods 901 are slidably connected with a clamping column 903 inside, and the top of the clamping column 903 is fixedly connected with a spring 904, and the other end of the spring 904 is fixedly connected with a connecting frame 905, and then the bottom of the connecting frame 905 is fixedly connected to the top of the fixing rod 901;

[0041] More specifically, in this embodiment, the ultrasonic probe 1 is connected to the imaging device and the recording device through a wire, and the imaging device and the recording device are installed on the examination bed body 21, so as to detect, diagnose and treat the patient at any time. When the device is used, first hold the handle 13 to take the shell 3 out of the support ring 20, then apply the coupling agent to the bottom of the ultrasonic probe 1, and then fix the sealing ring 2 through the outer wall of the ultrasonic probe 1, and the outer wall of the sealing ring 2 is fixedly connected to the shell 3, so that the shell 3 can be held by one hand to place the ultrasonic probe 1 on the surface of the pregnant woman's belly, and cooperate with the imaging device and the recording device to find the required part;

[0042] When the required part is found, the guide plate 6 is fixedly connected to the top of the rubber piston 5, and the top of the guide plate 6 is rotatably connected to the pull rod 7, and the top of the pull rod 7 extends through and extends to the outside of the shell 3, and the extended end of the pull rod 7 is fixedly connected to the handle 13, so that the handle 13 can be pulled outward by the other hand to drive the rubber piston 5 away from the sealing ring 2. At this time, the suction cup 4 is fixedly connected to the outer wall of the shell 3, and the outer wall of the rubber piston 5 and the inner wall of the shell 3 fit and slide, and the top of the sealing ring 2 is equidistantly penetrated by the rubber piston 5. A through hole 12 is opened, so that during the pulling process, a negative pressure state is formed between the sealing ring 2 and the rubber piston 5. At this time, they are connected through the through hole 12, so that the cavity formed by the suction cup 4 and the surface of the pregnant woman's belly is in a negative pressure state, thereby completing the preliminary positioning and fixing of the current position of the device quickly, and at the same time, the negative pressure can be controlled by controlling the distance that the handle 13 is pulled outward, so that the adsorption strength of the suction cup 4 can be controlled, and the adjustment is convenient and fast;

[0043] During the outward pulling process, the outer wall of the extended end of the pull rod 7 is symmetrically fixedly connected with a fixing block 8 at an equal distance, thereby synchronously driving the fixing block 8 to move. When the adjustment is completed, a fixing groove 902 is opened on the corresponding fixing block 8 on the side where the two fixing rods 901 are close to each other, and the outer wall of the fixing block 8 slides in contact with the inner wall of the fixing groove 902, so that the fixing block 8 is driven to move in a circle by rotating the handle 13 until it is screwed into the fixing groove 902. At this time, under the action of negative pressure, the rubber piston 5 has a force to move toward the ultrasonic probe 1, and then when the fixing block 8 is screwed into the fixing groove 902, it is quickly fixed and convenient to fix.

[0044] Then, a slot 14 is formed through the top of the fixing block 8 corresponding to the card column 903, and the card column 903 forms a telescopic structure with the connecting frame 905 through the spring 904, and the bottom of the card column 903 is truncated, so that when the fixing block 8 is screwed into the fixing groove 902, it first contacts the inclined surface of the card column 903, so that the card column 903 is forced to move in the direction of the spring 904 and compress the spring 904. When the bottom of the card column 903 is aligned with the card slot 14, the spring 904 rebounds and drives the card column 903 to be stuck in the card slot 14, and the secondary fixation is quickly completed to avoid accidental touching of the handle 13 to rotate and cause the adsorption to disappear;

[0045] As described above, when the required part is found, the current position of the device can be quickly and preliminarily positioned and fixed by pulling the handle 13 to avoid deviation during the fixing process. The adsorption strength of the suction cup 4 can then be controlled according to the pulling distance. The adjustment is convenient and fast, thereby ensuring the diagnostic and treatment efficiency of the device. At the same time, after the adsorption strength of the suction cup 4 is adjusted, the fixing block 8 can be driven by rotating the handle 13 to be clamped into the fixing groove 902 to complete the fixation, thereby maintaining the current adsorption strength and being easy to fix. The current adsorption strength can be further reinforced for a second time through the cooperation of the spring 904, the clamping column 903 and the clamping groove 14, thereby ensuring the diagnostic and treatment effect of the device.

[0046] Embodiment 2, on the basis of the above embodiment, the outer wall of the shell 3 is provided with grooves 10 at equal distances, and the inner wall of the groove 10 is provided with an auxiliary component 11, and the auxiliary component 11 is transmitted with the adsorption component, so that when the adsorption component is lifted or lowered, the auxiliary component 11 is used to control the corners of the suction cup 4, and then the inner wall of the groove 10 is provided with a through groove 15 corresponding to the auxiliary component 11, and the inner wall of the through groove 15 is provided with a limiting groove 16 corresponding to the auxiliary component 11, and the inner wall of the groove 10 is symmetrically provided with a circular groove 17 corresponding to the auxiliary component 11, and at the same time, the inner wall of the groove 10 is symmetrically provided with a sliding groove 18 corresponding to the auxiliary component 11.

[0047] Further, the auxiliary component 11 includes a first gear rod 1101, and then the two ends of the rotating rod 1103 are rotatably connected to the inner wall of the circular groove 17, and the outer wall of the rotating rod 1103 is fixedly connected with a transmission gear 1104 at an equal distance;

[0048] More specifically, in the present embodiment, when the required position is found and the handle 13 is pulled, the top of the guide plate 6 is in a truncated cone shape, so that when the guide plate 6 rises, the end of the first gear rod 1101 can be guided and squeezed by the inclined surface, so that the four first gear rods 1101 move away from each other, and the limiting strip 1106 is fixedly connected to the top of the first gear rod 1101, and the limiting strip 1106 has a T-shaped shape, and the outer wall of the limiting strip 1106 fits and slides with the inner wall of the limiting groove 16, so that the first gear rod 1101 can be supported and the moving direction can be limited by the limiting strip 1106, so as to ensure the stability of the first gear rod 1101 during the movement;

[0049] Then, a driving gear 1102 is meshed with the bottom of the first gear rod 1101, and a rotating rod 1103 is fixedly connected to the inner center of the driving gear 1102, so that when the first gear rod 1101 moves, the rotating rod 1103 can be driven to rotate by the driving gear 1102, and then a transmission gear 1104 is fixedly connected to the outer wall of the rotating rod 1103 at an equal distance, so that the transmission gear 1104 can be driven to rotate by the rotating rod 1103, and then a second gear rod 1105 is meshed with one side of the transmission gear 1104, and a connecting rod 1107 is fixedly connected to the bottom of the second gear rod 1105, and the two ends of the connecting rod 1107 are fitted and slid with the inner wall of the slide groove 18, so that the second gear rod 1105 can be supported and restricted by the connecting rod 1107 and the slide groove 18, and then the second gear rod 1105 can be driven to descend by the rotation of the transmission gear 1104;

[0050] Then, a connecting plate 1108 is fixedly connected to a side wall away from the ultrasonic probe 1 through the connecting rod 1107, and a connecting strip 1109 is hinged inside the connecting plate 1108, and the other end of the connecting strip 1109 is hinged to a connecting block 1110, and at the same time, the bottom of the connecting block 1110 is fixedly connected to the corner of the suction cup 4, so that in the process of pulling the handle 13, the connecting rod 1107 can be synchronously driven to descend, so that the corner of the suction cup 4 gradually contacts the surface of the pregnant woman's belly, completing the subsequent fixing effect, and then in the process of rotating the rotating rod 1103, one end of the torsion spring 1111 is overlapped on the outer walls of the two ends of the rotating rod 1103, and the other end of the torsion spring 1111 is overlapped on the inner wall of the circular groove 17, so that when the corner of the suction cup 4 contacts the surface of the pregnant woman's belly, the torsion spring 1111 is in a compressed state;

[0051] When it is necessary to release, the handle 13 can be rotated to make the fixing block 8 disengage from the fixing groove 902. At this time, firstly, with the assistance of negative pressure, the handle 13 is controlled to move toward the direction of the ultrasonic probe 1. When one end of the first gear rod 1101 contacts the inclined surface of the guide plate 6, it means that the negative pressure has been released. At this time, the torsion spring 1111 will assist and drive the multiple first gear rods 1101 to approach each other. Under the inclined surface of the guide plate 6, the guide plate 6 continues to move toward the direction of the ultrasonic probe 1. In the process after the negative pressure is released, the connecting rod 1107 will drive the corners of the suction cup 4 to gradually move upward until the rubber piston 5 contacts the top of the sealing ring 2. At this time, the corners of the suction cup 4 are away from the surface of the pregnant woman's belly, so as to avoid the corners of the suction cup 4 contacting the belly skin during the search process and triggering adsorption to affect the search efficiency. At the same time, it is also convenient for subsequent search of other required parts, thereby ensuring the efficiency of prenatal diagnosis and treatment.

[0052] As described above, in the process of finding the required part, the torsion spring 1111 can be used to control the corners of the suction cup 4 to avoid contact with the belly skin during the search process and triggering adsorption, which affects the search efficiency. At the same time, when the required part is found and the handle 13 is pulled, the corners of the suction cup 4 can be automatically brought into contact with the belly skin to complete the subsequent fixation effect, thereby further improving the diagnostic and treatment efficiency of the device.

[0053] Working principle: First, hold the handle 13 to remove the housing 3 from the support ring 20, then apply the coupling agent to the bottom of the ultrasound probe 1, then hold the housing 3 with one hand to place the ultrasound probe 1 on the surface of the pregnant woman's belly, and use imaging equipment and recording equipment to find and treat the required parts;

[0054] When the required part is found, the handle 13 can be pulled outward by the other hand to drive the rubber piston 5 away from the sealing ring 2, and the four first gear rods 1101 are moved away from each other through the guide plate 6, so that the corners of the suction cup 4 gradually contact the surface of the pregnant woman's belly;

[0055] When the corners of the suction cup 4 are in contact with the surface of the pregnant woman's belly, the cavity formed by the suction cup 4 and the surface of the pregnant woman's belly is in a negative pressure state, thereby completing the initial positioning and fixing. At the same time, the negative pressure can be controlled by controlling the distance that the handle 13 is pulled outward, thereby controlling the adsorption strength of the suction cup 4;

[0056] When the adjustment is completed, the handle 13 is rotated to drive the fixing block 8 to rotate into the fixing groove 902 to complete the quick fixation, and the spring 904 can drive the clamping column 903 to clamp into the clamping groove 14 to quickly complete the secondary fixation, avoiding the accidental touch of the handle 13 to rotate and cause the adsorption to disappear;

[0057] When the monitoring of the current part is completed and other parts need to be replaced, the handle 13 can be rotated to disengage the fixed block 8 from the fixed groove 902. Under the assistance of negative pressure, the handle 13 is controlled to move toward the direction of the ultrasonic probe 1. When one end of the first gear rod 1101 contacts the inclined surface of the guide plate 6, it means that the negative pressure has been released. At this time, the torsion spring 1111 will assist and drive multiple first gear rods 1101 to approach each other. Under the inclined surface of the guide plate 6, the guide plate 6 continues to move toward the direction of the ultrasonic probe 1. In the process after the negative pressure is released, the connecting rod 1107 will drive the corners of the suction cup 4 to gradually move upward until the rubber piston 5 contacts the top of the sealing ring 2. At this time, the corners of the suction cup 4 are away from the surface of the pregnant woman's belly, and the release state is completed. At this time, other parts can be found for treatment again.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
