Description

Technical Field

[0001] The present invention relates to the field of medical technology, and more specifically to a low-radiation-dose angiography system for inserting a cardiovascular stent. Background Art

[0002] The basic principle of cardiovascular angiography is to input two frames of X-ray images taken before and after the injection of contrast agent into an image computer through digitization, and eliminate the bone and soft tissue images on the angiography image through the process of subtraction, enhancement and re-imaging to obtain a clear pure vascular image. It is an examination method that combines electronic computers with conventional X-ray angiography. The angiography equipment mainly uses flat-panel detectors. Different from the image-enhanced angiography equipment in the past, the flat-panel detector type has the advantages of high spatial resolution, large dynamic range of imaging, small afterglow, rapid acquisition, and low radiation dose. The new generation of three-dimensional image fusion DSA system further reflects the characteristics of meeting various clinical needs. From the appearance point of view, angiography equipment is divided into two types: floor-standing and suspended.

[0003] However, there are still some shortcomings in its actual use. For example, when the current imaging equipment is used to photograph patients, due to the different heights and body shapes of various groups of people, the height adjustment range of the imaging equipment is limited in actual use, and it cannot meet the actual use of people with large height differences. At the same time, when the device is adjusted, the span of a single adjustment distance is large, and the speed cannot be effectively controlled, which makes it difficult for personnel to ensure the clarity of the imaging equipment during continuous shooting, thereby bringing difficulties to subsequent observations.

[0004] The existing structures and defects are studied and improved, and a low-radiation dose angiography system for cardiovascular stent implantation is provided, in order to achieve a more practical purpose. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a low-radiation dose angiography system for cardiovascular stent implantation. By setting a drive adjustment component, a fixed panel and a supporting side frame, and utilizing the mutual cooperation of the several components, first, the operator holds the fixed handle and then rotates it counterclockwise. At this time, the fixed handle drives the second pulley to rotate, and then drives the connecting belt to rotate counterclockwise through the second pulley, and then the connecting belt drives the first pulley at its top to rotate, and finally drives the driving gear on its side to rotate synchronously through the first pulley. At this time, the driving gear meshes and drives the fixed rack plate on the back side of the fixed panel to move upward, thereby raising the height of the scanning area plate on the front side of the fixed panel. Conversely, the fixed handle can be rotated clockwise to make the fixed panel move downward for adjustment, thereby improving the flexibility of the device and meeting the requirements of patients of different height types. At the same time, when rotating, the minimum unit is a tooth distance of the gear, thereby improving the accuracy of the device during adjustment, and the rotation of the gear and the belt is controlled by the handle, so that the stability is very high. Therefore, during development, the clarity is optimized, which facilitates subsequent observation, so as to solve the problems raised in the above-mentioned background technology.

[0015] Technical effects and advantages of the present invention:

[0016] 1. The present invention sets a driving adjustment component, a fixed panel and a supporting side frame, and utilizes the mutual cooperation of the several. First, the operator holds the fixed handle and then rotates it counterclockwise. At this time, the fixed handle drives the second pulley to rotate, and then drives the connecting belt to rotate counterclockwise through the second pulley, and then the connecting belt drives the first pulley at its top to rotate, and finally drives the driving gear on its side to rotate synchronously through the first pulley. At this time, the driving gear meshes and drives the fixed rack plate on the back side of the fixed panel to move upward, thereby raising the height of the scanning area plate on the front of the fixed panel. Conversely, the fixed handle can be rotated clockwise to make the fixed panel move downward for adjustment, thereby improving the flexibility of the device and meeting the requirements of patients of different heights. At the same time, when rotating, the minimum unit is a tooth distance of the gear, thereby improving the accuracy of the device during adjustment, and the rotation of the gear and the belt is controlled by the handle, so that the stability is very high. Therefore, during development, the clarity is optimized, which facilitates subsequent observation and improves the overall working effect of the device.

[0017] 2. The present invention sets a driving adjustment component, a locking structure and a supporting side frame, and utilizes the mutual cooperation of the several components. Subsequently, the limiting back plate on the side of the clamping rotating plate can be blocked by the locking pin, thereby locking it, and at the same time, it can be pulled out of the through hole, thereby loosening the clamping rotating plate, thereby achieving a flexible installation effect, and the clamping rotating plate is pressed by a compression spring, so that the arc-shaped opening on one side is fitted and clamped to the surface of the connecting shaft, thereby locking it, thereby locking the two pulleys, limiting the fixation and protecting the equipment, and then effectively locking the entire device to prevent it from rotating;

[0018] 3. The present invention provides a compression spring and a rotating plate. The elastic force of the compression spring can automatically drive the clamping rotating plate to rotate and clamp it to the surface of the connecting shaft, thereby improving the degree of automation of the device. During the rotation of the clamping rotating plate, the center of the fixed rotating rod on one side of the rotating plate is used as the basis to make a circular motion, thereby improving the stability and smoothness of the rotating plate during the rotation and clamping process, thereby improving the practicality of the device.

[0030] The drive adjustment structure 8 includes a pair of symmetrical fixed rack plates 81, the inner sides of the two fixed rack plates 81 are commonly connected with a reinforcing rib plate 82, the side of one of the fixed rack plates 81 is meshedly connected with a driving gear 83, the top end of the driving gear 83 is fixedly connected with a first pulley 84, the other end of the driving gear 83 is fixedly sleeved with a fixed shaft 85, the surface of the first pulley 84 is fitted with a connecting belt 86, the other end of the connecting belt 86 is fitted with a second pulley 87, the top of the second pulley 87 is fixedly connected with a fixed handle 88, the bottom end of the second pulley 87 A connecting shaft 89 is fixedly installed, and a driven gear 891 is meshedly connected to the side of the other fixed rack plate 81. A rotating shaft is set at the bottom end of the driven gear 891. The bottom end of the rotating shaft extends to the interior of the second fixed sleeve 10 and is rotatably sleeved therewith. The locking structure 9 includes a clamping rotating plate 91, and the side of the clamping rotating plate 91 is integrally formed with a limiting back plate 92. An arc-shaped opening 93 is opened on the other side of the clamping rotating plate 91. A rotating plate 94 is fixedly installed at the bottom end of the clamping rotating plate 91. A fixed rotating rod 95 is fixedly connected to the side of the rotating plate 94. A compression spring 96 is fixedly installed at the bottom end of the clamping rotating plate 91.

[0031] For details, please refer to the attached manual Figure 3-6 The other end of the compression spring 96 is fixedly mounted with a fixed back plate 97, and the left and right sides of the fixed back plate 97 are both inlaid with connecting side plates 98. The surfaces of the two connecting side plates 98 are both provided with through holes 99, and a locking pin 991 is detachably inserted into the inside of the through hole 99.

[0032] The specific implementation method is: a locking pin 991 is detachably inserted into the through hole 99, so that the locking pin 991 can block the limiting back plate 92 on the side of the clamping turn plate 91, thereby locking it, and at the same time can be pulled out from the through hole 99, thereby loosening the clamping turn plate 91, thereby achieving a flexible installation effect.

[0033] For details, please refer to the attached manual Figure 4-7 The compression spring 96 is fixedly installed on the side surface of the fixed back plate 97 and the surface of the supporting side frame 1 at an angle of forty-five to sixty degrees and is arranged at the bottom end of the clamping rotating plate 91. The left and right sides of the fixed slide groove 3 are respectively located on the same horizontal line with the outer sides of the two fixed rack plates 81. The surfaces of the driving gear 83 and the fixed rack plate 81 are evenly coated with a layer of lubricating grease. The bottom end of the fixed rotating shaft 85 extends to the interior of the second fixed sleeve 10 and is rotatably sleeved.

[0034] The specific implementation method is: a layer of lubricating grease is evenly coated on the surface of the driving gear 83 and the fixed rack plate 81, so that when the two are in relative meshing and sliding, the friction between the structural parts of the two can be reduced, thereby reducing the wear rate of the parts, and further ensuring the service life of the driving gear 83 and the fixed rack plate 81.

[0035] Working principle of the present invention:

[0036] Step 1: First, the operator assembles the various components of the device normally, and then starts the device normally.

[0037] Step 2: First, the operator holds the fixed handle 88 and then rotates it counterclockwise. At this time, the fixed handle 88 drives the second pulley 87 to rotate, and then the second pulley 87 drives the connecting belt 86 to rotate counterclockwise, and then the connecting belt 86 drives the first pulley 84 at its top to rotate, and finally the first pulley 84 drives the driving gear 83 on its side to rotate synchronously. At this time, the driving gear 83 engages and drives the fixed rack plate 81 on the back side of the fixed panel 5 to move upward, thereby raising the height of the scanning area plate 6 on the front side of the fixed panel 5. Conversely, the fixed handle 88 can be rotated clockwise to make the fixed panel 5 move downward for adjustment, thereby lifting its device. Flexibility can meet the requirements of patients of different heights. A locking pin 991 can be removably inserted into the through hole 99 later, so that the locking pin 991 can block the limiting back plate 92 on the side of the clamping turn plate 91, thereby locking it. At the same time, it can be pulled out from the through hole 99 to loosen the clamping turn plate 91, thereby achieving a flexible installation effect. The compression spring 96 is used to press the clamping turn plate 91 so that the arc-shaped opening 93 on one side fits and clamps to the surface of the connecting shaft 89, thereby locking it, thereby locking the two pulleys, limiting and fixing the equipment, and finally the device completes the scanning height adjustment process of the equipment.

[0038] Step 3: First, the operator shuts down the device normally, then checks whether the fixation between the various components of the device is normal, and then replaces and repairs the aged and severely worn parts inside the device.

[0039] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection.

In the absence of conflict, the same embodiment and different embodiments of the present invention can be combined with each other;
