A carotid artery compression hemostasis device for head and neck surgery

Abstract

The present invention provides a carotid artery pressurized hemostasis device for head and neck surgery, which belongs to the field of medical device technology. The device includes an adjustment mechanism, an arc-shaped rail is fixedly installed on the top of the adjustment mechanism, and a hemostasis device is movably installed on the inner side of the arc-shaped rail; the hemostasis device includes an arc-shaped block and a mounting hole. The hemostasis device of the present invention has significant advantages. During use, medical staff can conveniently adjust the angle and position of the hemostasis device according to the patient's wound condition. By rotating the second handle, the screw rod drives the slide, so that the hemostasis mechanism moves down smoothly to contact the wound. When pressure is applied, the buffer spring plays a role, effectively avoiding excessive pressure on the patient's neck, ensuring safe and comfortable operation. At the same time, the bottom plate moves up to squeeze the elastic water bag, and the water flows into the elastic hemostasis bag. As the slide moves further down, the elastic hemostasis bag expands and cooperates with the hemostasis plate, greatly improving the efficiency and accuracy of hemostasis, and providing strong protection for the treatment of patients.

Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly to a carotid artery compression hemostasis device for head and neck surgery. Background Art

[0002] The carotid artery is a large artery close to the heart. Once it ruptures and bleeds, it will cause shock or even death to the patient in a very short time. Therefore, timely and effective hemostasis of carotid artery bleeding is crucial. In previous medical practice, when encountering carotid artery injury or postoperative bleeding, manual pressure is often used. Others need to press the wound with both hands for a long time. This operation not only greatly increases the manpower burden, but also as the pressing time increases, the presser is very likely to become fatigued, which leads to a decline in pressing quality and difficulty in maintaining effective hemostatic pressure.

[0003] The traditional wrapping and compression method of hemostasis also has significant disadvantages. Due to the complex structure of the neck, the carotid artery is surrounded by the other carotid artery and important organs such as the trachea on the front of the neck. When using the wrapping and compression method to stop bleeding, it is easy to damage the other carotid artery if you are not careful, affecting its normal blood supply function, or causing compression to the trachea, hindering the patient's normal breathing, and causing serious complications.

[0004] To solve these problems, a Chinese patent with announcement number CN219183936U discloses a carotid artery surgical incision compression hemostasis device. The device achieves relatively precise compression hemostasis to a certain extent through the synergistic effect of structures such as the head fixing base, the neck arc support plate, the lower support rod, the neck arc clamping plate, the upper support rod and the hemostasis plate. It can only press the bleeding location, has the advantages of rapid hemostasis, long-term compression and uniform pressing force, and avoids damage to the trachea.

[0005] However, after an in-depth analysis of the performance of the device in actual applications, it is not difficult to find that it still has obvious limitations. When the base of the device is placed on the hospital bed, the inner hemostatic plate can only compress and stop bleeding on both sides of the neck. In actual clinical scenarios, the location of the bleeding point is not fixed on both sides of the neck. If the hemostatic point is located in other parts of the neck, such as on the upper part of the outer surface of the neck, the device will obviously not be able to be flexibly adjusted and adapted, and it is difficult to perform targeted squeezing and hemostasis at different positions of the neck. This greatly limits its application effect in complex bleeding situations. Summary of the Invention

[0018] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects:

[0019] In the above scheme, the adjustment mechanism of this device is extremely innovative in clinical applications, which greatly improves the flexibility and adaptability. During operation, the medical staff rotates the first handle. According to the principle of mechanical transmission, the first handle drives the first screw to rotate smoothly in the bottom rail. The rotation of the screw drives the movable block that cooperates with it to slide linearly along the predetermined track of the bottom rail, thereby pushing the top arc rail to produce displacement. The two arc rails adopt a unique sliding connection structure, which can be smoothly connected to form a ring rail under the drive of the movable block. By flexibly adjusting the sliding of the arc block in the arc rail, the spatial position and angle of the hemostasis device can be accurately adjusted in all directions. This enables the device to rotate flexibly around the patient's neck. No matter whether the wound is on the side, front or other complex positions of the neck, it can be accurately adapted, which greatly facilitates hemostasis operations for different patients and wound positions. After the adjustment is completed, twist the second screw on the first handle to insert it into the limit hole to self-lock and fix the first screw; manually twist the first screw to insert it into the mounting hole to assist in fixing the arc block and ensure the stability of the device.

[0020] After the hemostasis is completed, twist the third screw on the second handle and insert it into the card hole to lock the second screw, ensuring the stability of the device.

[0021] In clinical usage scenarios, the hemostatic mechanism replacement design of this device is extremely convenient. If hemostatic plates and elastic hemostatic bags of different specifications need to be replaced, medical staff only need to adjust the slide to move upward, and the slide squeezes the elastic water bag to disengage the bayonet from the snap-in hole, and then the existing parts can be quickly disassembled for replacement. When replacing, first insert the new mounting block into the mounting slot, and then insert the bayonet into the snap-in hole. After the elastic water bag is reset, squeeze the bayonet to stabilize the new part. This convenient replacement design is not only convenient and fast, but also makes the device reusable, fully meeting the diverse and personalized clinical needs. It can play an important role both in emergency treatment and routine medical scenarios, effectively improving medical efficiency and quality, and providing solid guarantees for medical treatment.

[0022] When the pressure detector detects that the water pressure in the elastic hemostatic bag reaches the set threshold, the second one-way valve and the first one-way valve are controlled to open, so that the water in the elastic hemostatic bag flows into multiple elastic massage bags through the liquid inlet pipe, avoiding excessive pressure on the hemostatic area and causing tissue damage. At the same time, the "excess pressure" is converted into massage power to achieve resource recycling. The impact pressure of the water flow drives multiple micro-rotating plates to rotate around the central axis. The rotation of the central axis drives the turntable to rotate through the rotating shaft and then drives the crank to make the movable block slide up and down along the slide groove on the inside of the limit block through the slider. When the movable block slides up and down, the micro-massage ball is driven to move back and forth up and down through the connecting rod, so that non-pressurized areas (such as the back of the neck and shoulders) can be gently massaged, improving the microcirculation of surrounding tissues and reducing the risk of local ischemia.

[0052] like Figures 1 to 11As shown, an embodiment of the present invention provides a carotid artery pressurization hemostasis device for head and neck surgery, comprising an adjustment mechanism 1 , a curved rail 2 is fixedly mounted on the top of the adjustment mechanism 1 , and a hemostasis device 3 is movably mounted on the inner side of the curved rail 2 . The hemostatic device 3 includes an arc-shaped block 31 and a mounting hole 32. The mounting holes 32 are arranged in an arc shape at equal intervals and are opened on the outside of the arc-shaped rail 2. The arc-shaped block 31 is slidably connected to the inside of the arc-shaped rail 2. A mounting arm 34 is fixedly installed on the outside of the arc-shaped block 31. A mounting frame 35 is fixedly installed on the top of the mounting arm 34. A base frame 36 is fixedly installed on the inside of the mounting frame 35. The base frame 36 is arranged in a "S" shape. An adjustment mechanism 37 is fixedly installed on the inside of the base frame 36. An elastic mechanism 38 is fixedly installed on the bottom of the adjustment mechanism 37. A hemostatic mechanism 39 is provided at the bottom of the elastic mechanism 38. A first screw 310 is threadedly connected to both sides of the top of the mounting frame 35. The bottom of the first screw 310 passes through the mounting frame 35 and is inserted into the inside of the mounting hole 32.

[0053] The combination of the adjustment mechanism 1 and the arc-shaped rail 2 of this device gives the hemostatic device 3 excellent flexibility. During clinical use, medical staff can flexibly adjust the position and angle of the hemostatic device 3 according to the specific location of the patient's wound. Whether it is located on the side of the neck, the front, or other complex parts of the wound, it can achieve precise adaptation, greatly improving the pertinence and effectiveness of the hemostatic operation. The sliding design of the arc-shaped block 31 inside the arc-shaped rail 2 facilitates quick alignment with the bleeding point, gaining precious time for timely hemostasis. The mounting arm 34 and the mounting frame 35 provide a stable support structure for the internal components, ensuring the stability of the entire device during operation. The base frame 36 is arranged in a "J" shape, which not only enhances the structural strength, It also facilitates the installation of the adjustment mechanism 37. The adjustment mechanism 37 can accurately adjust the position of the elastic mechanism 38 and the hemostasis mechanism 39 to meet the individual needs of different patients. The elastic mechanism 38 plays a key buffering role in the hemostasis process, effectively preventing the hemostasis mechanism 39 from causing excessive pressure on the patient's neck, and fully ensuring the safety and comfort of the operation process. In addition, the first screws 310 on both sides of the top of the mounting frame 35 cooperate with the mounting holes 32 arranged in an arc shape at equal intervals on the outside of the arc rail 2, which can firmly lock the arc block 31 after the adjustment is completed to prevent it from accidentally sliding during the hemostasis process, thereby ensuring the stability of the device and providing a solid guarantee for efficient and reliable carotid artery pressurization hemostasis.

[0054] like Figures 1 to 5As shown, the adjusting mechanism 1 includes a bottom rail 11, and a first screw rod 12 is rotatably connected to the inside of the bottom rail 11. The threads at both ends of the first screw rod 12 rotate in opposite directions, and both ends of the first screw rod 12 are threadedly connected to a movable block 13. The movable block 13 is slidably connected to the two ends inside the bottom rail 11, and the top of the movable block 13 is connected to the bottom of the guide rail. One end of the first screw rod 12 passes through the bottom rail 11 and is fixedly connected to a first handle 14. A fixed plate 15 is fixedly installed on the side of the bottom rail 11 close to the first handle 14, and limiting holes 16 are evenly spaced on the outside of the fixed plate 15. The high end of the first handle 14 is threadedly connected to a second screw rod 17, and the end of the second screw rod 17 passes through the adjusting handle and is inserted into the inside of the limiting hole 16.

[0055] The first screw rod 12 is rotatably connected to the bottom rail 11 of the device, and the threads at both ends thereof are rotated in opposite directions, so that when the first screw rod 12 is rotated, the movable block 13 threadedly connected at both ends can move in the same direction or in the opposite direction, and the position of the movable block 13 in the bottom rail 11 can be accurately and conveniently adjusted, thereby efficiently adjusting the position of the guide rail connected thereto and the upper hemostatic device 3, and quickly adapting to the complex conditions of the neck wounds of different patients. The sliding connection design of the movable block 13 and the bottom rail 11 ensures the stability and smoothness of movement. One end of the first screw rod 12 passes through the bottom rail 11 and is connected to the first handle 14, which is convenient for medical personnel to manually operate. The first screw rod 12 can be flexibly rotated according to actual needs. The setting of the fixed plate 15 and the limiting hole 16 cooperates with the second screw rod 17 threadedly connected to the first handle 14. After adjustment, the end of the second screw rod 17 can be inserted into the limiting hole 16 to lock the first screw rod 12 and prevent it from rotating due to accidental touch, etc., ensuring that the position of the hemostatic device 3 is stable during the hemostasis process, and providing reliable adjustment and stable support for the carotid artery pressurization hemostasis operation.

[0056] like Figures 5 to 9 As shown, the adjustment mechanism 37 includes a rail frame 371, which is fixedly installed inside the base frame 36, and the inside of the rail frame 371 is rotatably connected to a second screw rod 372, and the second screw rod 372 is rotatably connected to the inside of the rail frame 371.

The rail frame 371 is fixed to the inside of the base frame 36, providing a stable installation foundation, and the second screw rod 372 rotatably connected to the rail frame 371 cooperates with the slide 373 threadedly connected to the outer surface. When the second screw rod 372 is rotated, the slide 373 can slide smoothly inside the rail frame 371, realizing precise adjustment of the height and position of the elastic mechanism 38 and the bottom hemostasis mechanism 39, and can be flexibly adapted according to the patient's wound depth, position and other specific conditions to meet diverse hemostasis needs. The top of the second screw rod 372 passes through the rail frame 371 and is connected to the second handle 374, which is convenient for medical staff to manually operate and easy to control. The clamping holes 376 arranged in a ring at equal intervals on the top of the rail frame 371 cooperate with the third screw 375 threadedly connected to one side of the second handle 374. After adjusting the position of the hemostasis mechanism 39, the end of the third screw 375 is inserted into the clamping hole 376, which can effectively lock the second screw rod 372 to prevent it from accidentally rotating, ensuring the stable position of the hemostasis mechanism 39 during the hemostasis process. The first screw 310, the second screw 17, and the third screw 375 are all set to be hand-tightened, which is easy to operate and convenient for medical staff to quickly adjust and lock. The cross-section of the internal cavity of the movable block 13 and the bottom rail 11 is set to a convex shape, so that the movable block 13 is more stable when sliding in the bottom rail 11, and will not deviate or fall out, ensuring the smoothness and reliability of the entire adjustment process, and providing accurate and stable adjustment support for carotid artery pressurization hemostasis.

[0058] like Figures 5 to 8As shown, the elastic mechanism 38 includes a base plate 381, which is fixedly connected to the bottom of the slide 373, and a shell 382 is fixedly connected to both sides of the top of the base plate 381. A buffer spring 383 is fixedly connected to the interior of the shell 382, ​​and a sliding block 384 is fixedly connected to the bottom of the buffer spring 383. The bottom of the sliding block 384 is fixedly connected to a connecting rod 385. The bottom of the connecting rod 385 is connected to the top of the hemostatic mechanism 39. The hemostatic mechanism 39 includes a bottom plate 391, which is fixedly connected to the bottom of the connecting rod 385. A mounting groove 392 is provided on the inner side of the bottom plate 391, and a mounting block 393 is installed inside the mounting groove 392. The bottom of the mounting block 393 is fixedly installed with a hemostatic plate 39 4. A hemostatic component 6 is fixedly installed on the inner side of the hemostatic plate 394, and the hemostatic component 6 includes an elastic hemostatic bag 61 and a connecting tube 62. The elastic hemostatic bag 61 is fixedly connected to the bottom of the hemostatic plate 394, and the connecting tube 62 is fixedly connected to the top of the hemostatic plate 394. The bottom of the connecting tube 62 is connected to the interior of the elastic hemostatic bag 61, and an elastic water bag 63 is fixedly installed on the top of the connecting tube 62. The elastic water bag 63 is placed on the top of the bottom plate 391, and a bayonet 64 is fixedly connected to the bottom of the elastic water bag 63. A bayonet hole 65 is provided on the top of the bottom plate 391 and in the middle of the mounting block 393. The end of the bayonet pin 64 passes through the mounting hole 32 on the bottom plate 391 and is inserted into the bayonet hole 65 in the middle of the mounting block 393.

[0059] The elastic mechanism 38 and the hemostatic mechanism 39 of the device are exquisitely designed and practical, with outstanding advantages. In the specific elastic mechanism 38, the base plate 381 is fixed to the bottom of the slide 373, the shell 382 on both sides of the top and the internal buffer spring 383. When the hemostatic mechanism 39 contacts the patient's neck wound and applies pressure, the buffer spring 383 is compressed, and the sliding block 384 and the connecting rod 385 effectively buffer the pressure of the hemostatic mechanism 39 on the patient's neck, avoiding excessive pressure, ensuring safe and comfortable operation, and reflecting humanistic care. The bottom plate 391 of the hemostatic mechanism 39 is connected to the elastic mechanism 38 through the connecting rod 385. The design of the mounting groove 392 and the mounting block 393 allows for quick and easy replacement of hemostatic plates 394 of different specifications to meet diverse needs. The hemostatic component 6 on the inner side of the hemostatic plate 394, the elastic hemostatic bag 61 cooperates with the elastic water bag 63 and the connecting tube 62. When pressure is applied, the elastic water bag 63 is squeezed, and the water flows into the elastic hemostatic bag 61 through the connecting tube 62 to expand it, thereby enhancing the hemostatic effect. The arrangement of the latch 64 and the snap-in hole 65 secures the mounting block 393 and the hemostatic plate 394, ensuring the stability of the components during the hemostatic process, and providing a reliable and efficient solution for carotid artery pressurization hemostasis.

[0060] like Figures 9 to 11As shown, one side of the hemostatic plate 394 is provided with a plurality of elastic massage bags 67, and the plurality of elastic massage bags 67 are arranged in a non-pressurized area. The plurality of elastic massage bags 67 are connected to each other through a water conduit 68. One end of the elastic massage bag 67 is connected to the elastic hemostatic bag 61 through a liquid outlet pipe 66, and the other end of the elastic massage bag 67 is connected to the elastic hemostatic bag 61 through a liquid inlet pipe 69. A second one-way valve 5 is provided in the liquid inlet pipe 69, and a first one-way valve 4 is provided in the liquid outlet pipe 66. A pressure detector is provided in the elastic hemostatic bag 61, and the pressure detector is electrically connected to the first one-way valve 4 and the second one-way valve 5. A massage component 7 is provided in each of the elastic massage bags 67.

[0061] The massage component 7 includes a plurality of micro-rotating plates 71 arranged at the water conduit 68, one end of each of the micro-rotating plates 71 is fixedly connected to the central axis, and both ends of the central axis are connected to a turntable 72 through a rotating shaft, and each turntable 72 is fixedly connected to a crank 73 on the side away from the central axis, and one end of the crank 73 is movably connected to a movable block 74, and a limit block 75 is provided on the outer side of the movable block 74. The limit block 75 is fixedly installed on the inner wall of the elastic massage bag 67, and the movable block 74 is slidably connected to the sliding groove inside the limit block 75 through a slider. The bottom end of the movable block 74 slides through the limit block 75 through a connecting rod and is connected to a micro massage ball 76. By controlling the water pressure in the elastic hemostatic bag 61, the water is transported through the water pipe 68 in multiple elastic massage bags 67, and the impact pressure of the water flow drives multiple micro turn plates 71, turntables 72 and cranks 73 to rotate, thereby causing the movable block 74 to slide up and down along the limit block 75 and drive the micro massage ball 76 to move back and forth up and down through the connecting rod, so that non-pressurized areas (such as the back of the neck and shoulders) can be gently massaged, thereby improving the microcirculation of surrounding tissues and reducing the risk of local ischemia.

[0062] The technical solution provided by the present invention has the following workflow:

[0063] During operation, the medical staff manually rotates the first handle 14. According to the principle of mechanical transmission, the rotation of the first handle 14 accurately drives the first screw 12 connected to it, causing it to rotate smoothly inside the bottom rail 11. The rotation of the first screw 12 drives the movable block 13, which is threaded with it, to slide linearly along a predetermined track inside the bottom rail 11. The linear displacement of the movable block 13 pushes the arc-shaped rail 2 connected to its top to change its position synchronously. The two arc-shaped rails 2 adopt a unique sliding connection structure. Under the drive of the movable block 13, they can be smoothly docked and spliced ​​into a complete ring rail structure. At this time, by flexibly adjusting the sliding of the arc-shaped block 31 inside the arc-shaped rail 2, the spatial position and angle of the entire hemostatic device 3 can be precisely adjusted in all directions. With this adjustment mechanism, the hemostatic device 3 can be flexibly rotated around the patient's neck. According to the specific location of the wound on the patient's neck, whether it is the side, front or other complex positions, accurate and flexible adjustment and adaptation can be achieved, which greatly facilitates efficient hemostasis operations for different patients and different wound locations.

[0064] After completing the position and angle adjustment of the hemostatic device 3, to ensure its stability during the subsequent hemostatic process and prevent the device's position from changing due to factors such as accidental touch, the medical staff twists the second screw 17 on the first handle 14 to move it along the predetermined threaded path and accurately insert it into the limiting hole 16. Through this mechanical locking method, the first screw 12 is effectively self-locked and fixed, ensuring the stability of the device during use. When the angle of the hemostatic device 3 is adjusted to the ideal state, the medical staff manually twists the first screw 310 to move it and accurately insert it into the mounting hole 32. The mutual insertion and limiting effect between the first screw 310 and the mounting hole 32 assists in the clamping and fixing of the arc block 31, ensuring that the arc block 31 is stably fixed within the arc rail 2 without displacement or shaking. This adjustment mechanism 1 not only enables flexible and precise adjustment of the angle of the hemostatic device 3, but also is equipped with a reliable double locking function, greatly improving the convenience and adaptability of the device in actual clinical use, and providing strong support for medical staff's operation.

[0065] The hemostatic device 3 equipped with this device is designed with full consideration of the actual needs of the clinical front line. It has two significant advantages: efficient hemostasis and convenient replacement. After completing the angle and position adjustment of the hemostatic device 3 according to the patient's wound condition, the medical staff rotates the second handle 374 to drive the second screw rod 372 inside the rail frame 371 to rotate smoothly. Based on the mature mechanical cooperation principle between the screw rod and the slide 373, the rotation of the second screw rod 372 drives the slide 373 to slide smoothly along the preset track inside the rail frame 371. The sliding of the slide 373 pushes the base plate 381 connected to its bottom to move downward. The downward movement of the base plate 381 drives the connected hemostatic mechanism 39 to move downward synchronously. When the hemostatic mechanism 39 contacts the wound on the patient's neck, as the applied pressure gradually increases, the buffer spring 383 is squeezed and produces corresponding expansion and contraction deformation. The expansion and contraction of the buffer spring 383 effectively plays a buffering role, preventing the hemostatic mechanism 39 from causing excessive pressure on the patient's neck, ensuring the safety and comfort of the entire hemostatic operation process.

[0066] When the hemostatic mechanism 39 contacts the patient's neck and continuously applies pressure, the bottom plate 391 moves upward by the reaction force from the wound, thereby squeezing the elastic water bag 63 placed in advance on its top. The elastic water bag 63 is pre-filled with an appropriate amount of water. When squeezed, the water is orderly transported to the elastic hemostatic bag 61 through the connecting tube 62. The medical staff continues to rotate the second handle 374, and the second screw rod 372 further drives the slide 373 to move downward. The downward movement of the slide 373 causes the buffer spring 383 inside the shell 382 to be further compressed, thereby applying a greater squeezing force to the elastic water bag 63. Under the action of the greater squeezing force, the elastic water bag 63 transports more water to the elastic hemostatic bag 61, causing the elastic hemostatic bag 61 to further expand. The expanded elastic hemostatic bag 61 can squeeze the patient's bleeding wound more stably, and work together with the hemostatic plate 394 to achieve a more efficient and accurate hemostatic effect. When the liquid is transported to the elastic hemostatic bag 61, when the pressure detector detects that the water pressure in the elastic hemostatic bag 61 reaches the set threshold, the second one-way valve 5 and the first one-way valve 4 are controlled to open, so that the water in the elastic hemostatic bag 61 flows into the multiple elastic massage bags 67 through the liquid inlet pipe 69, avoiding excessive pressure on the hemostatic area and causing tissue damage. At the same time, the "excess pressure" is converted into massage power to achieve resource recycling. When the water is transported in the multiple elastic massage bags 67 through the water conduit 68, the impact pressure of the water flow drives the multiple micro-rotating plates 71 to rotate around the central axis. The rotation of the central axis drives the turntable 72 to rotate through the rotating shaft, and then drives the crank 73 to make the movable block 74 slide up and down along the inner groove of the limit block 75 through the slider. When the movable block 74 slides up and down, it drives the micro-massage ball 76 to move back and forth up and down through the connecting rod, so that the non-pressurized area (such as the back of the neck and shoulders) can be gently massaged, improving the microcirculation of the surrounding tissues and reducing the risk of local ischemia.

[0067] After completing the hemostatic pressure operation, in order to lock the second screw rod 372 to prevent it from changing the hemostatic pressure due to accidental rotation and affecting the hemostatic effect, the medical staff twists the third screw rod 375 on the second handle 374 to make it insert into the clamping hole 376 along the threaded path. Through the mutual limiting effect between the third screw rod 375 and the clamping hole 376, the second handle 374 is stably fixed, thereby achieving effective locking of the second screw rod 372, ensuring the stability and reliability of the hemostatic device 3 during use. During actual use of this device, if it is necessary to replace the hemostatic pressure plate 394 and the elastic hemostatic bag 61 of different specifications, it is only necessary to adjust the slide 373 to move upward, and the upward movement of the slide 373 squeezes the elastic The water bag 63 causes the latch 64 to disengage from the inside of the latch hole 65. At this time, medical staff can quickly disassemble the existing elastic hemostatic bag 61 and the blood pressure plate 394 and replace them. During replacement, the new mounting block 393 is inserted into the mounting groove 392, and then the latch 64 is inserted into the inner side of the latch hole 65. After the elastic water bag 63 is reset, the latch 64 is squeezed to ensure that the newly replaced elastic hemostatic bag 61 can be firmly installed. The hemostatic device 3 of this device can not only provide an efficient and reliable hemostatic function, but also has a convenient and fast hemostatic mechanism 39 replacement design, which can realize the reuse of the device, fully meet the diverse and personalized clinical needs, and provide strong technical support for medical treatment.
