Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a mobile lifting frame. Background Technology

[0002] The content in this section only provides background information related to this utility model and may not constitute prior art.

[0003] In surgeries such as knee arthroscopy and shoulder arthroscopy, irrigating the surgical area with sterile saline is one of the key steps in the procedure. Irrigation with sterile saline not only removes blood, tissue debris, and foreign bodies from the surgical area, but also maintains a clear surgical field, reduces the risk of infection, and thus ensures the smooth progress of the surgery.

[0004] To achieve the desired flushing effect, sterile saline solution needs to be under pressure. Typically, the sterile saline bottle containing the solution needs to be suspended at a certain height above the ground so that gravity forces the saline solution to flow out and generate appropriate flushing pressure. Furthermore, during actual surgery, the flushing pressure may need to be dynamically adjusted depending on the surgical site, patient position, and the progress of the surgery. This necessitates the ability to flexibly adjust the height of the sterile saline bottle.

[0005] However, the common way to suspend sterile saline bottles is to hang them on ordinary IV stands. Since ordinary IV stands do not have height adjustment capabilities, medical staff often need to manually adjust the height of the sterile saline bottle. This method is not only cumbersome, labor-intensive, and inefficient, but the adjusted height of the sterile saline bottle may also be inaccurate. Summary of the Invention

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments. The same reference numerals in the accompanying drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Compared to the embodiments shown in the accompanying drawings, feasible embodiments within the scope of protection of this utility model may have fewer components, have other components not shown in the drawings, different components, components arranged differently, or components with different connections, etc. Furthermore, two or more components shown in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.

[0022] Example 1

[0023] Embodiment 1 of this utility model provides a mobile lifting frame, which is at least suitable for suspending sterile saline bottles at a certain height above the ground during surgeries such as knee arthroscopy and shoulder arthroscopy, so as to use pressurized sterile saline to irrigate the surgical area.

[0024] Figure 1 This is a schematic diagram of the structure of an exemplary mobile lifting frame disclosed in Embodiment 1 of this utility model. Figure 2 for Figure 1 A cross-sectional view of the movable lifting frame is shown. Figure 1 and Figure 2 In the embodiment shown, the mobile lifting frame may include a support frame 10, a height adjustment mechanism 20, a suspension assembly 30, and a control panel 40.

[0025] The support frame 10 is mainly used to provide a carrier for the installation of the height adjustment mechanism 20 and the control panel 40, and to support the entire mobile lifting frame on the ground.

[0026] Specifically, refer to Figure 1 and Figure 2 As shown, the support frame 10 may include a base 11 and a column 12. The column 12 extends along the height direction and is disposed on the base 11. The column 12 may be a hollow component to define an area within the column 12 such as... Figure 2 The accommodating cavity 121 is shown. The base 11 may have a rectangular structure, and the base 11 is provided with multiple outwardly extending extension arms 13. Each extension arm 13 is provided with a roller or other movable component 14 at its bottom, so that the support frame 10 has the ability to move, thereby facilitating the movement of the entire mobile lifting frame to different positions for use. Furthermore, the design of the extension arms 13 helps to improve the stability of the entire mobile lifting frame when it is supported on the ground.

[0027] The height adjustment mechanism 20 is mounted on the support frame 10, and particularly within the receiving cavity 121 inside the column 12, so that the column 12 provides protection for the height adjustment mechanism 20. Furthermore, the height adjustment mechanism 20 is configured to output reciprocating motion along the height direction. The height adjustment mechanism 20 can be a known device suitable for outputting reciprocating linear motion, such as a hydraulic cylinder, pneumatic cylinder, electric actuator, linear module, etc. For example, the height adjustment mechanism 20 described in this invention can be a hydraulic cylinder, so that the height adjustment mechanism 20 can output reliable and stable reciprocating motion, thereby facilitating more accurate control of the height position of the sterile saline bottle.

[0028] When the height adjustment mechanism 20 is a hydraulic cylinder, the output end of the height adjustment mechanism 20 (which can be understood as the output shaft of the hydraulic cylinder) extends beyond the top of the column 12 so as to facilitate the integrated installation of the suspension assembly 30 on the output end of the height adjustment mechanism 20.

[0029] The suspension assembly 30 is disposed at the output end of the height adjustment mechanism 20, so that it can reciprocate along the height direction under the drive of the height adjustment mechanism 20. The suspension assembly 30 includes a hook 31 suitable for suspending sterile saline bottles. The hook 31 may be a generally J-shaped component to facilitate the suspension of the sterile saline bottles.

[0030] The control panel 40 can be mounted on the support frame 10, particularly on the outer wall of the column 12, to optimize the overall structural design of the mobile lifting frame. Furthermore, the height adjustment mechanism 20 is communicatively connected to the control panel 40. The control panel 40 is used for human-machine interaction, allowing control commands to be sent to the height adjustment mechanism 20, which in turn responds to these commands and performs corresponding actions.

[0031] For example, buttons such as "Parameter Setting," "Up," and "Down" can be set on the control panel 40 to achieve different functions. For instance, the "Parameter Setting" button is used to input parameters for controlling the travel of the suspension assembly 30; the "Up" and "Down" buttons are used to control the upward and downward movement of the height adjustment mechanism 20, respectively. Additionally, the control panel 40 can also have buttons such as "Start" and "Emergency Stop." The "Start" button is used to power on the relevant electrical components of the entire mobile lifting frame, while the "Emergency Stop" button is used to stop the relevant electrical components of the entire mobile lifting frame in case of an emergency.

[0032] Based on the above setup, when actually using the mobile lifting frame disclosed in this embodiment, the entire mobile lifting frame is first moved to the target position by the moving part 14 of the support frame 10. Then, the sterile saline bottle can be suspended on the hook 31 of the suspension assembly 30. Based on this, medical personnel can input the stroke of the suspension assembly 30 along the height direction according to the target height position of the sterile saline bottle corresponding to the surgical area irrigation needs using the control panel 40. Subsequently, the medical personnel press the corresponding control button, and the height adjustment mechanism 20 drives the suspension assembly 30, along with the sterile saline bottle, to move along the height direction to the target height position, thereby relying on the sterile saline bottle at the target height position to output sterile saline that meets the pressure required for surgical area irrigation.

[0033] As can be seen, the mobile lifting frame disclosed in the embodiments of this utility model, by adding a height adjustment mechanism 20 that can drive the suspension component 30 used to suspend the sterile saline bottle to move back and forth in the height direction, and in conjunction with the control panel 40, can assist medical staff in automatically adjusting the height position of the sterile saline bottle. This design not only simplifies the operation of adjusting the height position of the sterile saline bottle, reduces the intensity of manual labor, and improves efficiency, but also enables more accurate adjustment of the height position of the sterile saline bottle.

[0034] In some embodiments, combined with Figure 3 As shown, the suspension assembly 30 may include multiple hooks 31 to allow for the suspension of a greater number of sterile saline bottles at a time.

[0035] In addition, the suspension assembly 30 may further include a rotary drive component 32, which is disposed at the output end of the height adjustment mechanism 20. Furthermore, the rotary drive component 32 includes a rotary shaft 321 capable of outputting horizontal rotational motion. For example, the rotary drive component 32 may be a motor.

[0036] In this arrangement, multiple hooks 31 of the suspension assembly 30 are sequentially arranged on the rotation shaft 321 along the circumference of the rotation shaft 321, so as to drive the multiple hooks 31 to rotate in the horizontal plane through the rotation shaft 321.

[0037] Understandably, by setting multiple hooks 31 and adding a rotary drive component 32 to drive multiple hooks 31 to rotate in the horizontal plane, it is not only beneficial to hang more sterile saline bottles on the suspension assembly 30, but also, when medical staff need to use sterile saline bottles at different horizontal positions, they only need to use the rotary drive component 32 to drive the corresponding hook 31 and the sterile saline bottle hanging on it to the position of the medical staff, without the medical staff having to adjust their own position, thus improving the convenience for medical staff to use sterile saline bottles at different horizontal positions.

[0038] The rotary drive component 32 can also be connected to the control panel 40 so that the control panel 40 can send control commands to the rotary drive component 32 to control its operation, thereby making the rotary drive component 32 work automatically in response to the corresponding control commands.

[0039] In some embodiments, continue to refer to Figure 3 When there are multiple hooks 31, the suspension assembly 30 may further include a mounting ring 33 sleeved on the rotation shaft 321 of the rotation drive component 32, the mounting ring 33 being coaxial with the rotation shaft 321. Multiple hooks 31 are disposed on the mounting ring 33.

[0040] The installation ring 33 facilitates the convenient installation of multiple hooks 31 on the rotating shaft 321 of the rotary drive component 32, and also facilitates the overall replacement of multiple hooks 31.

[0041] In some embodiments, refer to Figure 1 As shown, the support frame 10 may also include a handle 15. For example, the handle 15 may be mounted on the column 12. The handle 15 facilitates the easy movement of the entire mobile lifting frame by medical personnel.

[0042] Example 2

[0043] Based on Embodiment 1, considering the case where the rotation drive component 32 is located at the output end of the height adjustment mechanism 20, and the rotation drive component 32 is communicatively connected to the control panel 40, refer to... Figure 4 As shown, a communication cable 50 exists between the rotary drive component 32 and the control panel 40. Therefore, when the rotary drive component 32 moves back and forth along the height direction, to avoid interference with the communication cable 50, the length of the communication cable 50 between the rotary drive component 32 and the control panel 40 is usually required to be sufficiently long. However, in this way, as the rotary drive component 32 continuously moves back and forth along the height direction, the communication cable 50 may become tangled and messy, thus affecting the normal use of the mobile lifting frame.

[0044] Therefore, Embodiment 2 of this utility model discloses another improved mobile lifting frame. Unlike Embodiment 1, the mobile lifting frame disclosed in Embodiment 2 may further include a retraction assembly 60. This retraction assembly 60 is suitable for retracting the communication cable 50 between the rotary drive component 32 and the control panel 40, so as to reduce the risk of it becoming tangled during the movement of the rotary drive component 32.

[0045] Specifically, structure Figure 4 and Figure 5 As shown, the take-up and take-up assembly 60 may include a take-up and take-up roller 61 and a take-up and take-up drive mechanism 62.

[0046] The take-up and release roller 61 has a first end and a second end. The first end of the take-up and release roller 61 is rotatably mounted on the support frame 10, and in particular, is rotatably mounted in the receiving cavity 121 inside the column 12; the second end of the take-up and release roller 61 extends horizontally. The take-up and release roller 61 is drively connected to the take-up and release drive mechanism 62 so that the take-up and release roller 61 is driven to rotate about its own axis by the take-up and release drive mechanism 62.

[0047] For the communication cable 50 between the rotary drive component 32 and the control panel 40, the first end of the communication cable 50 is connected to the control panel 40, such as... Figure 5 As shown, the second end of the communication cable 50 extends from the center of the second end of the take-up roller 61 into the interior of the take-up roller 61 and then exits through the circumferential outer wall of the take-up roller 61. The communication cable 50 that exits through the circumferential outer wall of the take-up roller 61 is wound around the circumferential outer wall of the take-up roller 61 and then connected to the rotary drive component 32. The communication cable 50 is bonded and fixed to the take-up roller 61 when it exits through the circumferential outer wall of the take-up roller 61.

[0048] Understandably, by setting up the take-up and release assembly 60, the excess communication cable 50 between the rotary drive component 32 and the take-up and release roller 61 can be wound around the take-up and release roller 61, so that the take-up and release roller 61 can take up and release this part of the communication cable 50 to adapt to the position of the rotary drive component 32.

[0049] Specifically, assuming that in the initial state, the rotary drive component 32 is at its lowest position under the action of the height adjustment mechanism 20, the communication cable 50 between the take-up and release rollers 61 and the rotary drive component 32 is in a taut state. On this basis, when the rotary drive component 32 moves upward under the drive of the height adjustment mechanism 20, the take-up and release drive mechanism 62 simultaneously drives the take-up and release rollers 61 to rotate, so that the line is continuously released through the take-up and release rollers 61. As a result, the communication cable 50 between the rotary drive component 32 and the take-up and release rollers 61 gradually becomes longer as the rotary drive component 32 moves upward, so as to adapt to the position change of the rotary drive component 32. Correspondingly, when the rotary drive component 32 moves downward under the drive of the height adjustment mechanism 20, the take-up and release drive mechanism 62 simultaneously drives the take-up and release roller 61 to rotate in the opposite direction, so that the line is continuously taken up through the take-up and release roller 61. This causes the communication cable 50 between the rotary drive component 32 and the take-up and release roller 61 to be continuously wound around the take-up and release roller 61, thereby making the communication cable 50 between the rotary drive component 32 and the take-up and release roller 61 gradually shorter as the rotary drive component 32 moves downward, in order to adapt to the position change of the rotary drive component 32. During the upward or downward movement of the rotary drive component 32, since the communication cable 50 between the take-up and release roller 61 and the control panel 40 passes through the center of the second end of the take-up and release roller 61, the length of the communication cable 50 between the take-up and release roller 61 and the control panel 40 does not change with the rotation of the take-up and release roller 61.

[0050] In this way, the communication cable 50 between the rotary drive component 32 and the take-up roller 61 is taken up and put down during the continuous reciprocating movement of the rotary drive component 32 along the height direction, thereby reducing the risk of the communication cable 50 becoming tangled during the movement of the rotary drive component 32.

[0051] In some embodiments, the retraction drive mechanism 62 may be constructed in the following manner, but is not limited to.

[0052] Combination Figure 5 As shown, the retraction drive mechanism 62 may include a rack 621 and a gear 622. The rack 621 extends along the height direction and can move synchronously with the rotary drive component 32. For example, the rack 621 may be connected to the output end of the height adjustment mechanism 20. Of course, in other embodiments of this invention, the rack 621 may also be directly connected to the rotary drive component 32. The gear 622 is coaxially arranged with the take-up and take-down rollers 61 and is connected to each other for transmission, so that the two can rotate synchronously. Furthermore, the gear 622 meshes with the rack 621 for transmission.

[0053] With this configuration, when the rotary drive component 32 moves along the height direction under the drive of the height adjustment mechanism 20, the gear 622 and the take-up / release roller 61 can rotate synchronously through the transmission engagement of the gear 622 and rack 621. Furthermore, as the direction of movement of the rotary drive component 32 changes, the rotation direction of the take-up / release roller 61 also changes, allowing for the take-up and release of the communication cable 50. This design eliminates the need for an additional drive device to rotate the take-up / release roller 61, achieving the take-up and release of the communication cable 50 between the rotary drive component 32 and the take-up / release roller 61 while simultaneously reducing the operating cost of the mobile lifting frame.

[0054] In some embodiments, the take-up and unwind assembly 60 may further include two limiting members 63, which are disposed opposite to each other on the take-up and unwind roller 61 along the axial direction. The communication cable 50, extending from the circumferential outer wall of the take-up and unwind roller 61, is wound between the two limiting members 63. The limiting members 63 effectively limit the communication cable 50 wound on the take-up and unwind roller 61, preventing it from detaching from the roller.

[0055] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
