Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a medical imaging gantry with an adjustment mechanism. Background Technology

[0002] Mobile digital X-ray machines are suitable for use in radiology departments, orthopedics departments, wards, emergency rooms, operating rooms, and intensive care units, meeting the needs for digital imaging of various parts of the body, including the head, limbs, chest, spine, lumbar spine, and abdomen. Mobile DR machines can perform bedside imaging without transferring patients, providing convenience for both medical staff and patients. Compared to traditional diagnostic radiology equipment, mobile DR imaging is easier to operate, has a simpler workflow, faster imaging speed, and can adapt to different environments and usage scenarios.

[0003] In recent years, lightweight mobile DR has become increasingly prominent in radiological diagnostics. A lightweight DR machine consists of a head unit, detector, acquisition workstation, mechanical moving trolley, and lifting and folding arm assembly to perform imaging in various patient positions. Among the overall structure of the mobile DR, the lifting and folding of the head unit is particularly important, allowing for adjustment of the head unit's height for imaging. In actual use, the head unit is generally mounted on a lifting and folding arm assembly to perform lifting and locking functions. Due to the need to bear a large weight, and the limitations of size and weight in lightweight mobile DR, it is generally supported by gas springs to complete the lifting and folding function.

[0004] Among the relevant technical means, refer to Figure 1 Folding arms supported by gas springs on the market are generally fixed support structures. The main structure of the fixed spring support consists of column 2, support shaft 412, movable shaft 423, support arm 413, gas spring support shaft 427, detection head 3, and gas spring 421.

[0005] Regarding the aforementioned technical means, the operating force at certain specific angles during the raising and lowering of the machine head is very large, making it difficult to operate. For example, the operating force is greatest when the folding arm is at 45°. When the fulcrum gas spring fulcrum is adjusted upward, the operating force at the 45° angle will decrease, but the operating force at the 130° angle will increase. Thus, there is a problem of large operating force and low convenience during the adjustment of the machine head. Summary of the Invention

[0006] To address the issue of high operating force and low convenience during the adjustment of the camera head, this application provides a medical imaging gantry equipped with an adjustment mechanism.

[0007] This application provides a medical imaging gantry with an adjustment mechanism, which adopts the following technical solution:

[0008] A medical imaging gantry with an adjustment mechanism includes a pusher base, a column, an imaging head, and an adjustment support arm. The column is vertically fixed to the pusher base. One end of the adjustment support arm is fixedly connected to the column, and the other end is fixedly connected to the imaging head. The adjustment support arm includes a support component and an adjustment component. One side of the support component and one side of the adjustment component are both fixedly connected to the column, and the support component is located above the adjustment component. The other side of the support component is rotatably connected to the other side of the adjustment component. The support component includes a fixed connecting plate, a support shaft, and a support arm. One side of the fixed connecting plate is mounted on the top of the column, and the support arm is disposed on the other side of the fixed connecting plate. One side of the support arm is connected to the support shaft. The rotating shaft is rotatably connected, and the detection head is fixedly connected to the side of the support arm away from the support rotating shaft. The adjustment assembly includes a gas spring, a support mounting bracket, a movable rotating shaft, a balance spring, and a spring limiting block. The support mounting bracket is mounted on the column and has a movable waist-shaped hole. The movable rotating shaft can slide and rotate within the movable waist-shaped hole. One end of the gas spring is rotatably connected to the movable rotating shaft, and the other end is rotatably connected to the support arm. The spring limiting block is located on the support mounting bracket. One end of the balance spring abuts against the movable rotating shaft, and the other end abuts against the spring limiting block. The balance spring is in a compressed state. When the pressure on the gas spring is greater than the elastic force of the balance spring, the movable rotating shaft moves along the length direction of the movable waist-shaped hole.

[0009] By adopting the above technical solution, during the up-and-down movement of the inspection head, when the support arm and the column are clamped at 45 degrees, the gas spring is in a compressed state and the pressure is at its maximum. At this time, the operating force required to move the inspection head is the maximum. At this time, the gas spring presses against the balance spring through the movable shaft. When the pressure on the gas spring is greater than the elastic force of the balance spring, the movable shaft moves along the length direction of the movable waist-shaped hole, and the axial distance between the support shaft and the movable shaft decreases. At the same time, due to the movement of the movable shaft, the piston rod of the gas spring can relax to a certain extent under the compressed state, and achieve a state in which the pressure of the gas spring and the pressure of the balance spring are balanced, thereby reducing the operating force required to move the inspection head.

[0010] Optionally, the compression spring limiting block is fixedly connected to the support mounting bracket, and the installation direction of the compression spring limiting block is the same as the extension direction of the movable waist-shaped hole.

[0011] By adopting the above technical solution, the simplicity of the adjustment components can be maintained as much as possible, while still achieving the function of reducing the distance between the movable pivot and the support pivot.

[0012] Optionally, the adjustment assembly further includes a directional shaft, which is fixed on the compression spring limiting block, and the balance compression spring is sleeved on the outer circumferential surface of the directional shaft.

[0013] By adopting the above technical solution, the possibility of the balance spring disengaging from the movable shaft and the spring limiting block is reduced when the balance spring is in a compressed state.

[0014] Optionally, the adjustment assembly further includes a gas spring support shaft, which is rotatably connected to the side of the gas spring away from the support mounting bracket. The support arm has a support waist-shaped hole, and the gas spring support shaft can slide and rotate within the support waist-shaped hole.

[0015] By adopting the above technical solution and supporting the waist-shaped hole, the gas spring can move not only at the other end of the movable shaft, but also at the other end. This allows the gas spring to have a slack for relaxation in the compressed state, further reducing the operating force required to move the detection head.

[0016] Optionally, the movable shaft has an anti-detachment groove, and the balancing spring abuts against the bottom of the anti-detachment groove.

[0017] By adopting the above technical solution, since the movable rotating shaft is cylindrical, the balance spring may detach when it is pressed against the non-planar surface under excessive pressure. The anti-detachment groove can reduce the risk of detachment due to excessive pressure.

[0018] Optionally, the column includes a sliding mounting block, the support mounting bracket is fixed on the sliding mounting block, the side wall of the column has a mounting groove, and the height of the mounting groove is greater than the height of the sliding mounting block, and the sliding mounting block slides in the mounting groove.

[0019] By adopting the above technical solution, when the operating force of the moving inspection head is too large, the sliding mounting block can be actively slid upward, reducing the distance between the moving shaft and the supporting shaft, making the moving inspection head move more easily.

[0020] Optionally, the mounting groove is open at the top of the column, and the column further includes a sliding limiting block. The sliding limiting block is fixed in the mounting groove and has a sliding gap with the sliding mounting block. A reciprocating spring is provided in the sliding gap, with one end of the reciprocating spring abutting against the sliding limiting block and the other end abutting against the sliding mounting block.

[0021] By adopting the above technical solution, the reciprocating spring can prevent the sliding mounting block from abutting the sliding limit block, allowing the sliding mounting block to be moved manually as much as possible, thereby reducing the operating force selectively by the user.

[0022] Optionally, the mounting groove has an inner groove and an outer groove, the width of the inner groove is greater than that of the outer groove, so that the mounting groove is stepped, the inner groove is located inside the mounting groove on the column, and the shapes of the sliding limit block and the sliding mounting block match the shape of the mounting groove.

[0023] By adopting the above technical solution, when the sliding mounting block slides in the mounting groove, the step of the sliding mounting block abuts against the step of the mounting groove, thus restricting the detachment of the sliding mounting block.

[0024] Optionally, the sliding mounting block has a first abutting groove on the side facing the sliding limiting block that abuts against the reciprocating spring, and the sliding limiting block has a second abutting groove on the side facing the sliding mounting block that abuts against the reciprocating spring.

[0025] By adopting the above technical solution, the setting of the first abutting groove and the second abutting groove can also reduce the risk of disengagement due to the reciprocating spring being compressed to too extreme.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Reduce wheelbase. During the up-and-down movement of the inspection head, when the clamping angle between the support arm and the column is approximately 45 degrees, the gas spring is compressed and at its maximum pressure. This requires the greatest operating force to move the inspection head. At this point, the gas spring presses against the balance spring via the movable shaft. When the pressure on the gas spring exceeds the spring force of the balance spring, the movable shaft moves along the length of the movable slot, reducing the wheelbase between the support shaft and the movable shaft. Simultaneously, due to the movement of the movable shaft, the piston rod of the gas spring can relax to a certain extent under compression, achieving a balance between the pressure of the gas spring and the balance spring, thereby reducing the operating force required to move the inspection head.

[0028] 2. Active control to reduce wheelbase. The gas spring is indirectly connected to the sliding mounting block through the movable pivot and the support mounting bracket. Under the force of the gas spring, the sliding mounting block may continuously abut against the sliding limit block. The reciprocating spring can prevent the sliding mounting block from abutting against the sliding limit block, so that the sliding mounting block can be moved manually as much as possible, thereby selectively reducing the operating force.

[0043] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0044] This application discloses a medical imaging gantry with an adjustment mechanism. (See also...) Figure 2 and Figure 3 A medical imaging gantry with an adjustment mechanism includes a pusher base 1, a column 2, an imaging head 3, and an adjustment support arm 4. The pusher base 1 is placed on the ground, the column 2 is vertically mounted on the pusher base 1, one end of the adjustment support arm 4 is connected to the column 2, and the imaging head 3 is connected to the other end of the adjustment support arm 4. Specifically, the adjustment support arm 4 includes a support component 41 and an adjustment component 42.

[0045] Reference Figure 3 and Figure 4 The support assembly 41 includes a fixed connecting plate 411, a support rotating shaft 412, and a support arm 413. The fixed connecting plate 411 is fixedly installed on the top of the column 2. The support rotating shaft 412 passes through the left side of the fixed connecting plate 411 and rotates on the fixed connecting plate 411. The right side of the support arm 413 is rotatably connected to the support rotating shaft 412. The detection head 3 is fixedly installed on the left side of the support arm 413. The adjustment assembly 42 includes a gas spring 421, a support mounting bracket 422, a movable rotating shaft 423, a balance spring 424, a spring limiting block 425, a directional shaft 426, and a gas spring support shaft 427. The support mounting bracket 422 is fixedly installed on the left side of the column 2. The support mounting bracket 422 has a movable waist-shaped hole 4221 and a movable cavity 4222. The movable cavity 4222 is open at the top, bottom, and left side of the support mounting bracket 422 to form two protruding ends 4223. The movable waist-shaped hole 4221 is provided on the protruding ends 4223. The length direction of the movable waist-shaped hole 4221 is located at a 45-degree angle with the horizontal plane and faces the column 2. The movable rotating shaft 423 is rotatably connected to the movable waist-shaped hole 4221 and can slide back and forth along the length direction of the movable waist-shaped hole 4221.

[0046] Reference Figure 3 and Figure 5 The support arm 413 has a support waist-shaped hole 4131 at one end near the inspection head 3. The length direction of the support waist-shaped hole 4131 is the length direction of the support arm 413, and the support waist-shaped hole 4131 is set perpendicular to the axis of the support arm 413. The gas spring support shaft 427 is rotatably connected to the support waist-shaped hole 4131 and can slide back and forth along the length direction of the support waist-shaped hole 4131. One end of the gas spring 421 is rotatably connected to the movable rotating shaft 423, and the other end is rotatably connected to the gas spring support shaft 427. The compression spring limit block 425 is installed on the support mounting bracket 422. One end of the balance compression spring 424 abuts against the movable rotating shaft 423, and the other end abuts against the compression spring limit block 425. At this time, the balance compression spring 424 is in a compressed state.

[0047] Reference Figure 4 and Figure 6During the up-and-down movement of the inspection head 3, when the angle between the support arm 413 and the column 2 is 45 degrees, the gas spring 421 is in a compressed state and the pressure is at its maximum. At this time, the operating force required to move the inspection head 3 is the maximum. At this time, the gas spring 421 presses against the balance spring 424 through the movable shaft 423. When the pressure on the gas spring 421 is greater than the elastic force of the balance spring 424, the movable shaft 423 moves along the length direction of the movable waist-shaped hole 4221. The axial distance between the support shaft 412 and the movable shaft 423 decreases. At the same time, due to the movement of the movable shaft 423, the piston rod of the gas spring 421 can relax to a certain extent under the compressed state, and achieve a state of mutual balance between the pressure of the gas spring 421 and the pressure of the balance spring 424, thereby reducing the operating force required to move the inspection head 3. Meanwhile, the setting of the support waist-shaped hole 4131 allows the gas spring 421 to move not only to the other end of the movable rotating shaft 423, but also to allow the gas spring 421 to have a relaxation margin in the compressed state, further reducing the operating force required to move the detection head 3.

[0048] Reference Figure 7 In this embodiment, the compression spring limiting block 425 is located in the movable cavity 4222 and locked to the inner wall of the support mounting bracket 422 by bolts. The movable rotating shaft 423 passes through the support mounting bracket 422 and both ends of the movable rotating shaft 423 are respectively located in the movable waist-shaped hole 4221. The movable rotating shaft 423 slides and engages with the support mounting bracket 422 through the movable waist-shaped hole 4221. When the moving inspection head 3 is in motion, the gas spring 421 rotates up and down, that is, the gas spring 421 rotates relative to the movable shaft 423. The movable shaft 423 is located in the movable waist-shaped hole 4221 and does not rotate. When the support arm 413 and the column 2 are clamped at 45 degrees, the gas spring 421 is in a compressed state and the pressure is at its maximum. The movable shaft 423 moves along the length direction of the movable waist-shaped hole 4221, so that the pressure of the gas spring 421 and the pressure of the balance spring 424 are balanced. This reduces the operating force required to move the inspection head 3, while maintaining the simplicity of the adjustment component 42 as much as possible, and still achieving the function of reducing the distance between the movable shaft 423 and the support shaft 412.

[0049] Furthermore, to position the compression spring 424, a compression spring limiting block 425 passes through the directional shaft 426. One end of the directional shaft 426 is fixed to the compression spring limiting block 425, and the other end is mounted on the movable shaft 423. The balance compression spring 424 is sleeved on the outer circumferential surface of the directional shaft 426. This reduces the possibility of the balance compression spring 424 detaching from the movable shaft 423 and the compression spring limiting block 425 when it is under compression. Specifically, the outer circumferential surface of the movable shaft 423 has an anti-detachment groove 4231. One end of the directional shaft 426 abuts against the bottom of the anti-detachment groove 4231 and is fixedly connected to the movable shaft 423. The anti-detachment groove 4231 reduces the risk of the directional shaft 426 detaching due to excessive pressure.

[0050] Reference Figure 8 The column 2 includes a sliding mounting block 21 and a sliding limiting block 23. The side of the column 2 facing the inspection head 3 has a mounting groove 22. The mounting groove 22 opens at the top of the column 2 and extends downward. The sliding limiting block 23 is fixedly installed on the upper part of the mounting groove 22. At the same time, the top surface of the sliding limiting block 23 and the top surface of the column 2 coincide and are covered by a fixed connecting plate 411. The sliding mounting block 21 slides in the remaining space of the mounting groove 22. There is a space between the sliding mounting block 21 and the sliding limiting block 23, forming a sliding gap 24. The support mounting bracket 422 is fixedly installed on the side of the sliding mounting block 21. This allows the sliding mounting block 21 to slide upward actively when the operating force of the moving inspection head 3 is too large, reducing the distance between the movable rotating shaft 423 and the support rotating shaft 412, making the moving inspection head 3 easier.

[0051] A reciprocating spring 25 is provided in the sliding gap 24. One end of the reciprocating spring 25 abuts against the sliding mounting block 21, and the other end abuts against the sliding limiting block 23. The gas spring 421 is indirectly connected to the sliding mounting block 21 through the movable rotating shaft 423 and the support mounting bracket 422. Under the force of the gas spring 421, the sliding mounting block 21 may continuously abut against the sliding limiting block 23. The reciprocating spring 25 can prevent the sliding mounting block 21 from abutting against the sliding limiting block 23, allowing the sliding mounting block 21 to be moved manually as much as possible, thereby selectively reducing the operating force. The side of the sliding mounting block 21 facing the sliding limiting block 23 has a first abutting groove 211 that abuts against the reciprocating spring 25, and the side of the sliding limiting block 23 facing the sliding mounting block 21 has a second abutting groove 231 that abuts against the reciprocating spring 25. The first abutting groove 211 and the second abutting groove 231 can also reduce the risk of the reciprocating spring 25 disengaging due to being compressed to its limit.

[0052] Reference Figure 8 and Figure 9The mounting groove 22 is divided into an inner groove 221 and an outer groove 222. The width of the inner groove 221 is greater than the width of the outer groove 222. Therefore, the mounting groove 22 has a stepped shape. The outer groove 222 opens on the side of the column 2, and the inner groove 221 is closer to the center of the column 2. At the same time, the shapes of the sliding mounting block 21 and the sliding limiting block 23 match the shape of the mounting groove 22 and are both stepped. This allows the sliding mounting block 21 to slide into the mounting groove 22, with the stepped part of the sliding mounting block 21 abutting against the stepped part of the mounting groove 22, thus restricting the sliding mounting block 21 from detaching.

[0053] The implementation principle of a medical imaging gantry with an adjustment mechanism according to an embodiment of this application is as follows:

[0054] During the up-and-down movement of the inspection head 3, when the clamping angle between the support arm 413 and the column 2 is approximately 45 degrees, the gas spring 421 is in a compressed state and the pressure is at its maximum. At this time, the operating force required to move the inspection head 3 is at its maximum. At this time, the gas spring 421 presses against the balance spring 424 through the movable shaft 423. When the pressure on the gas spring 421 is greater than the elastic force of the balance spring 424, the movable shaft 423 moves along the length direction of the movable waist-shaped hole 4221, and the axial distance between the support shaft 412 and the movable shaft 423 decreases. At the same time, due to the movement of the movable shaft 423, the piston rod of the gas spring 421 can relax to a certain extent under the compressed state, and the pressure of the gas spring 421 and the pressure of the balance spring are balanced, thereby reducing the operating force required to move the inspection head 3. Simultaneously, the movable sliding mounting block 21 causes the support mounting frame 422 to actively move closer to the fixed connecting plate 411, actively reducing the axial distance and further reducing the operating force required to move the inspection head 3.
