Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a nursing frame for abdominal surgery based on operating room nursing. Background Art

[0002] Laparoscopic surgery is a newly developed minimally invasive surgical procedure. It requires minimal incision and offers significant results, making it widely used. Laparoscopic surgery nursing racks are used to display necessary tools during surgery, making it easier for surgeons to access them. This prevents panic during the most demanding situations, shortens surgical procedures, and alleviates pain. Laparoscopic surgery nursing racks offer significant benefits to both surgeons and patients, leading to their widespread adoption and development in the medical industry. However, existing nursing racks still have certain drawbacks. Because the fixed trays on the racks hold the necessary supplies, they are often inconvenient for medical staff to access, reducing surgical efficiency.

[0003] To this end, the Chinese patent publication number "CN214858652U" discloses a "laparoscopic surgery nursing stand for operating room nursing", the main structure of which includes a base and a support column. The inner wall of the base is fixedly connected to the support column, the surface of the support column is movably connected to a collar, the surface of the support column is movably connected to a limit block by a bolt, the surface of the collar is fixedly connected to a connecting rod, and the number of the connecting rods is four, two of which are fixedly connected to square nursing trays at one end, and the other two are fixedly connected to circular nursing trays at one end. The bottom of the support column is fixedly connected to a support block, and one end of the support block is fixedly connected to a placement block. When the support rod moves downward inside the support column, the first spring movably connects the block to the button, so that the support plate supports the entire nursing stand. Pressing the button will eject the block and move the support rod upward. Tightening the limit bolt will fix the support rod in the support column, thereby facilitating the movement of the entire nursing stand.

[0004] However, the above-mentioned abdominal surgery nursing frame for operating room nursing changes the angle of the square nursing tray by rotating the ring, and the connection relationship between the ring and the support column is a nested connection. The friction between the ring and the support column cannot be controlled, resulting in the ring easily having too much or too little rotational resistance when rotating. If the rotational resistance is too large, the square nursing tray will be difficult to move, which is not conducive to taking instruments located inside different square nursing trays, and if the rotational resistance is too small, the square nursing tray will be too flexible and the braking accuracy will be low. Summary of the Invention

The elastic strength of the spring is utilized to generate a certain braking friction force between the brake ring and the longitudinal support column.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1 and Figure 2 , a nursing stand for abdominal surgery based on operating room nursing, includes a bottom supporting base plate 1 with a universal roller 2 installed below, a longitudinal supporting column 3 installed on the upper surface of the bottom supporting base plate 1, a No. 1 rod through-hole 4 arranged at the center of the bottom supporting base plate 1 and the longitudinal supporting column 3 and with the top and bottom ends both open, and an instrument placement tray 5 and a garbage storage bin 6 located around the longitudinal supporting column 3. The longitudinal supporting column 3 is pushed and, under the action of the universal roller 2, it is moved to the working area, and then the instruments required for the operation are placed in the instrument placement tray 5, and the garbage generated during the operation is thrown into the garbage storage bin 6.

[0025] In order to make the rotation resistance of the instrument placement tray 5 and the garbage storage bin 6 tend to be within a moderate range, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4, it is necessary to set up a controllable rotation mechanism 7, which is provided with a hollow sleeve 71 installed on the outer periphery of the column of the longitudinal support column 3 through a bearing and with a hollow interior, which plays a connecting and supporting function for the instrument placement tray 5 and the garbage storage bin 6; a radial hollow shell 75 which is integrally provided on the outer circumference of the hollow sleeve 71 and has a hollow interior; a brake ring 711 which can move axially along the radial hollow shell 75 and can resist the outer circumference of the column of the longitudinal support column 3; and a brake ring 711 which is placed inside the radial hollow shell 75 and can generate elastic pressure on the brake ring 711 toward the longitudinal support column 3.

When the instrument placement tray 5 and the garbage storage bin 6 are rotating, they need to overcome this friction force. When the force during rotation is greater than the friction force, the instrument placement tray 5 and the garbage storage bin 6 can be rotated. When the rotation force is less than the friction force, the instrument placement tray 5 and the garbage storage bin 6 will stop in time, so that the rotation resistance of the instrument placement tray and the garbage storage bin can be brought into a moderate range, thereby ensuring the movement accuracy and stability of the instrument placement tray.

[0026] For the specific structure of the controllable rotating mechanism 7, please refer to Figure 3 and Figure 4, including a hollow sleeve 71, the center of which is provided with a central sleeve cavity 72, and the two end surfaces of the hollow sleeve 71 are provided with shaft mounting holes 74, and the hollow sleeve 71 is mounted on the cylindrical surface of the longitudinal support column 3 through a bearing at the position located in the shaft mounting hole 74, and the outer circumferential surface of the hollow sleeve 71 is provided with a radial docking plate 73 which is an integral structure therewith and can be connected to the instrument placement tray 5 and the garbage storage bin 6, and the outer circumferential surface of the hollow sleeve 71 is provided with a radial hollow shell 75 which is an integral structure therewith, and a component movable cavity 76 is provided inside the radial hollow shell 75, and one end of the component movable cavity 76 is communicated with the side of the central sleeve cavity 72 through the No. 2 rod body through-hole 77, and the radial hollow shell 75 is located at the component movable cavity 76 An inner movable plate 78 capable of axially moving along the component movable cavity 76 is placed inside, and a radial interference rod 710 that passes through the No. 2 rod body through-hole 77 is fixedly installed on the end face of the inner movable plate 78 facing the No. 2 rod body through-hole 77, and a coil spring 79 is placed on the other end of the inner movable plate 78, and one end of the radial interference rod 710 is fixedly installed with a brake ring 711 that interferes with the column surface of the longitudinal support column 3, one end of the coil spring 79 interferes with the corresponding end face of the inner movable plate 78, and the other end interferes with one end of the inner cavity of the radial hollow shell 75, and the initial length of the coil spring 79 is greater than the axial depth of the component movable cavity 76, and when the brake ring 711 interferes with the column surface of the longitudinal support column 3, there is a gap between the two ends of the inner movable plate 78 and the two end faces of the component movable cavity 76.

[0027] To achieve the bottoming out braking function of the device, refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6 , it is necessary to set up an adsorption type brake mechanism 8, which is provided with an upper fan-shaped permanent magnet 88 fixedly mounted on the bottom of the bottom support base plate 1, a lower brake disc 82 located directly below the upper fan-shaped permanent magnet 88 and capable of longitudinally moving relative to the upper fan-shaped permanent magnet 88 and in contact with the ground, a lower fan-shaped permanent magnet 89 fixedly connected to the lower brake disc 82 and capable of generating a magnetic attraction effect with the upper fan-shaped permanent magnet 88, and a longitudinal active member that passes through the through hole 4 of the No. 1 rod body and can drive the lower brake disc 82 to move longitudinally. When the movable rod 84 moves, the cap 85 is pulled upward, and the longitudinal movable rod 84 will drive the lower fan-shaped permanent magnet 89 to move upward until the lower fan-shaped permanent magnet 89 is adsorbed on the bottom of the upper fan-shaped permanent magnet 88. At this time, the device can be moved. When braking is required, the cap 85 is pressed downward to make the lower fan-shaped permanent magnet 89 separate from the upper fan-shaped permanent magnet 88 and move downward. Under the action of gravity, the bottom of the lower brake disc 82 is in contact with the ground, and at this time, a braking effect can be achieved.

[0029] When in use, when moving, pull the cap 85 upward, the longitudinal movable rod 84 will drive the lower fan-shaped permanent magnet 89 to move upward until the lower fan-shaped permanent magnet 89 is adsorbed on the bottom of the upper fan-shaped permanent magnet 88. At this time, the device can be moved. When braking is needed, press and pull the cap 85 downward to make the lower fan-shaped permanent magnet 89 separate from the upper fan-shaped permanent magnet 88 and move downward. Under the action of gravity, the bottom of the lower brake disc 82 is in contact with the ground. At this time, the braking effect can be achieved, and the instruments required for the operation are placed in the instrument placement tray 5, and the garbage generated during the operation is placed in the garbage storage bin 6. When the instrument placement tray 5 and the garbage storage bin 6 are rotating, they need to overcome the friction force. When the rotation force is greater than the friction force, the instrument placement tray 5 and the garbage storage bin 6 can be rotated.
