DETAILED DESCRIPTION

[0029] The present invention will be further described below with reference to the accompanying drawings.

[0030] like Figure 1 As shown, the preferred embodiment of the present invention's mobile display screen bracket for critical care ultrasonic puncture includes a base 1, a robotic arm 2, and a fixing clamp 3. The fixing clamp 3 is used to clamp the display screen 5. It should be noted that the display screen 5 can be connected to the ultrasound instrument through wireless communication and display the ultrasound results. The fixing clamp 3 is installed on the robotic arm 2. The robotic arm 2 can adjust its position and angle at will. In this way, the angle and position of the fixing clamp 3 can be adjusted, thereby changing the angle and position of the display screen 5, which can better display the ultrasound structure and make it more convenient for doctors to operate. The robotic arm 2 can use the existing one. The robotic arm 2 is detachably mounted on the base 1. The base 1 is used to be fixed to the bedside guardrail 4. The base 1 can install the robotic arm 2 and the fixing clamp 3 on the bedside guardrail 4 of the ICU bed. The robotic arm 2 and the base 1 are installed in a detachable manner. The robotic arm 2 can be installed without the robotic arm 2 when the base 1 is installed, which makes it more convenient to install the base 1.

[0031] like Figures 2 to 4As shown, the base 1 includes a first clamping seat 11, a second clamping seat 12, a locking screw 13, a first clamping plate 14, a second clamping plate 15 and a mounting plate 16. The upper end of the first clamping seat 11 is hinged to the upper end of the second clamping seat 12, and the lower end of the first clamping seat 11 is locked with the lower end of the second clamping seat 12 by the locking screw 13, thereby clamping the first clamping seat 11 and the second clamping seat 12 on the rod 41 of the bedside guardrail 4. That is, after the first clamping seat 11 and the second clamping seat 12 are locked, a clamping hole 10 is formed, and the rod 41 is located in the clamping hole 10. The first clamping plate 14 is sleeved on the locking screw 13. Rotating the locking screw 13 can move the first clamping plate 14 toward the second clamping plate 15, thereby clamping the first clamping plate 14 and the second clamping plate 15 on the baffle 42 of the bedside guardrail 4, preventing the first clamping seat 11 and the second clamping seat 12 from turning over, and ensuring the stability of the base 1. The mounting plate 16 is disposed on the first clamping seat 11 , and the robotic arm 2 is mounted on the mounting plate 16 .

[0032] Specifically, the first clamping seat 11 extends outward on a side away from the second clamping seat 12 to form the mounting plate 16, that is, the mounting plate 16 is integrally formed with the first clamping seat 11, thereby reducing the number of assembly steps. The first clamping seat 11 is provided with a first receiving groove on a side close to the second clamping seat 12, and the second clamping seat 12 is provided with a second receiving groove on a side close to the first clamping seat 11, and the first receiving groove and the second receiving groove form a clamping hole 10. The lower end of the first clamping seat 11 is provided with a through hole adapted to the locking screw 13, and the locking screw 13 passes through the through hole to connect with the second clamping seat 12. The use of the through hole can facilitate the locking screw 13 to quickly pass through the first clamping seat 11 and connect with the second clamping seat 12; of course, in other embodiments, the lower end of the first clamping seat 11 can also be provided with a screw hole adapted to the locking screw 13. The lower end of the second clamping seat 12 is provided with a locking screw hole adapted to fit the locking screw 13. The locking screw 13 passes through the through hole and is screwed into the locking screw hole, thereby locking the first clamping seat 11 and the second clamping seat 12. The locking screw 13 includes a rod body 131 for connecting to the second clamping seat 12 and a gripping portion 132 connected to the rod body 131 and used to apply force. The first clamping plate 14 is sleeved on the rod body 131. In this way, when the locking screw 1 locks the first clamping seat 11 and the second clamping seat 12, the first clamping plate 14 abuts between the first clamping seat 11 and the gripping portion 132, ensuring that the gripping portion 132 does not abut against the first clamping seat 11, making it easier to apply force to the gripping portion 132. When installing the base 1, flip the second clamp seat 12 to the other side of the headboard guardrail 4. At this time, the locking screw 13 is not screwed into the second clamp seat 12. Then screw the locking screw 13 into the second clamp seat 12 and tighten it to ensure that the first clamp seat 11 and the second clamp seat 12 are clamped on the rod 41, and the first clamp plate 14 and the second clamp plate 15 are clamped on the baffle 42. In this way, even if subjected to external force, the base 1 cannot rotate around the headboard guardrail 4, ensuring that the base 1 can be stably fixed on the headboard guardrail 4.

[0033] like Figures 5 to 7As shown, the fixing clamp 3 includes a fixed plate 31, a movable plate 32, a first spring 33, a locking mechanism 34, a lifting rod 35, and a movable handle 36. The fixed plate 31 is fixed to the robot arm 2, and the movable plate 32 is slidably arranged on the movable plate 32. The movable plate 32 and the fixed plate 31 are both provided with clamping hooks 37 for fixing the display screen 5. The first spring 33 is used to reset the movable plate 32, thereby providing a downward force to the movable plate 32, so that the clamping hooks 37 on the movable plate 32 and the clamping hooks 37 on the fixed plate 31 clamp the display screen 5. The locking mechanism 34 is used to lock the movable plate 32 and limit it to the highest position. That is, the movable plate 32 slides upward on the fixed plate 31. When the movable plate 32 slides to the highest position, the locking mechanism 34 locks the position of the movable plate 32. When the locking mechanism 34 releases the restriction on the movable plate 32, the first spring 33 drives the movable plate 32 to reset, thereby automatically clamping the display screen 5. The lifting rod 35 is mounted on the movable plate 32. The lifting rod 35 is used to pull the movable plate 32, thereby providing a fulcrum for pulling the movable plate 32. This allows for better pulling of the movable plate 32 without having to pull the clamping hook 37. This protects the clamping hook 37 of the movable plate 32 and extends the service life of the clamping hook 37. The movable handle 36 is fixed to the fixed plate 31. Holding the movable handle 36 can drive the entire fixed clamp 3 to move. When the display screen 5 needs to be moved, only the movable handle 36 needs to be held without touching other parts. The movable handle 36 can be sterilized in advance to ensure aseptic operation even if the display screen 5 needs to be moved during the puncture process.

[0034] like Figure 8 As shown, the movable plate 32 includes a connecting portion 321, a sliding portion 322 and a reset abutting portion 323. The sliding portion 322 is connected to the connecting portion 321. The reset abutting portion 323 is arranged on the sliding portion 322. The sliding portion 322 is U-shaped. The reset abutting portion 323 is arranged at the U-shaped bottom of the sliding portion 322. There are three reset abutting portions 323. In other embodiments, the reset abutting portion 323 can also be one or more, which can be set according to needs.

[0035] like Figure 9As shown, the fixed plate 31 includes a plate body 311 and a cover plate 312. The plate body 311 is provided with a first slide groove 3111 and a second slide groove 3112. The first slide groove 3111 is U-shaped. The sliding portion 322 of the movable plate 32 slides in the first slide groove 3111. The first spring 33 is placed in the second slide groove 3112. The return abutment portion 323 of the movable plate 32 slides in the second slide groove 3112. The upper end of the first spring 33 abuts the top of the second slide groove 3112, and the lower end of the first spring 33 abuts the return abutment portion 323 of the movable plate 32. The cover plate 312 is fixed to the plate body 311 to limit the thickness direction of the slide groove, ensuring that the movable plate 32 cannot be separated from the thickness direction. The U-shaped sliding portion 322 and the first slide groove 3111 can prevent the movable plate 32 from separating from the fixed plate 31 in the height direction and can also limit the upward and downward sliding positions of the movable plate 32. Since the movable plate 32 cannot be directly inserted into the fixed plate 31 , the fixed plate 31 is provided with two parts, namely a plate body 311 and a cover plate 312 , so as to facilitate the assembly of the movable plate 32 onto the fixed plate 31 .

[0036] like Figures 8 to 11As shown, the locking mechanism 34 includes a trigger pin 341, a locking pin 342, a sealing plug 343, and a second spring 344. A first receiving hole 3113 is provided on the fixing plate 31. The first receiving hole 3113 penetrates the fixing plate 31 in the thickness direction and is used to accommodate the trigger pin 341. One end of the trigger pin 341 extends out of the fixing plate 31, facilitating the pressing of the trigger pin 341. The first receiving hole 3113 and the trigger pin 341 are both T-shaped. The diameter of the trigger pin 341 near the display screen 5 is smaller than the diameter of the trigger pin 341 away from the display screen 5. This effectively prevents the trigger pin 341 from falling off the side of the fixing plate 31 in contact with the display screen 5. When the locking cam 342 is unlocked, the locking cam 342 is unlocked and the locking cam 343 is unlocked, so that the locking cam 342 can be unlocked when the locking cam 342 is unlocked. The end of the locking pin 342 proximal to the trigger pin 341 is provided with an arcuate guide surface 3421, which guides the locking pin 342 out of the first receiving hole 3113 even when it is not fully released. Thus, even if the locking pin 342 is not fully released from the first receiving hole 3113, the first spring 33 can still allow the locking pin 342 to release from the first receiving hole 3113, thereby unlocking the movable plate 32. When the movable plate 32 is moved to its uppermost position, the second receiving hole 3231 aligns with the first receiving hole 3113, and the locking pin 342 is pushed into the first receiving hole 3113 by the second spring 344. As a result, the locking pin 342 partially pushes the trigger pin 341 out of the first receiving hole 3113, thereby securing the movable plate 32. When unlocking is required, the trigger pin 341 is pressed, and the trigger pin 341 pushes the locking pin 342 out of the first receiving hole 3113 , and the movable plate 32 moves downward under the action of the first spring 33 , so that the clamping hook 37 automatically clamps and fixes the display screen 5 .

[0037] When the display screen 5 needs to be clamped, the display screen 5 is placed on the clamping hook 37 on the fixing plate 31 and leaned on the fixing plate 31 , and the display screen 5 is pressed at the same time, and the display screen 5 can be automatically fixed and clamped 3 tightly under the action of the first spring 33 .

[0038] The movable handle 36 is L-shaped, which is convenient for applying force by turning it left and right, and also convenient for applying force by turning it up and down, making adjustment more convenient.

[0039] When the doctor needs to move the display screen 5 during ultrasound-guided puncture, he or she can hold the moving handle 36 to move the display screen 5 and adjust the angle, so that the display screen 5 is in the best position, which can better perform ultrasound-guided puncture and shorten the time of ultrasound-guided puncture.

[0040] The above is only an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure made using the contents of the description and drawings of the present invention, directly or indirectly used in other related technical fields, is also within the patent protection scope of the present invention.
