Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a double-concave lifting operating table. Background Art

[0002] When performing microsurgical operations on the hand in a hospital, precise operation is required, and the operation time is relatively long. The surgeon is prone to trembling due to arm fatigue, which may lead to the failure of the operation. Therefore, a wide platform is needed to place the patient's arm and support the surgeon's forearm to complete delicate microsurgical operations. Secondly, some surgical devices need a platform to be placed, and most of the usage methods of such devices are foot-operated devices. Moreover, when performing some orthopedic surgeries, fluoroscopic imaging is required.

[0003] For example, the Chinese utility model patent with the authorization announcement number CN 205612564 U discloses a stepless variable-speed adjustable hand support for microsurgical operations, which is more practical and convenient during the operation. The hand support is small and light, uses a pneumatic spring as the power system, can easily adjust the height arbitrarily, and the switch for adjusting the height is located at the bottom of the hand support, and the operator can control it with the foot. However, its disadvantages are as follows: 1. The hand support has no moving casters and is not convenient to move; 2. There is no bottom plate at the lower part of the hand support, and for surgeries that require auxiliary equipment, additional devices are needed to place the equipment; 3. The upper table surface has no concave design, does not conform to ergonomics, and wastes physical strength during use; 4. The table surface is not X-ray transmissive, which is not convenient for surgical fluoroscopy; 5. The single column has potential safety hazards and is not convenient for fluoroscopy. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a double-concave lifting operating table.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The present utility model will be further described below through specific embodiments in conjunction with the drawings.

[0032] Embodiment 1:

[0033] Such as Figures 1-3As shown in FIGS. 5, a double-concave lifting operating table includes a top plate 2 and a base support 4. One side of the base support 4 is connected to one side of the top plate 2 through a lifting support rod 3, and the other side of the base support 4 is connected to the other side of the top plate 2 through a gas spring lifting rod 7. The gas spring lifting rod 7 includes a lifting upper rod 71 connected to the top plate 2, a lifting lower rod 73 connected to the base support 4, a gas spring release rod 9 installed on the top plate 2, and a gas spring 72. The lifting upper rod 71 is slidably sleeved with the lifting lower rod 73. The gas spring 72 is installed inside the lifting upper rod 71 and the lifting lower rod 73. The upper end of the piston rod of the gas spring 72 is provided with a gas spring release button 74, and the gas spring release button 74 is connected to the gas spring release rod 9 through a pull rope 75.

[0034] Embodiment 2:

[0035] A double-concave lifting operating table, different from Embodiment 1 in that the gas spring release button 74 is connected to the lifting upper rod 71 through a pin shaft 76.

[0036] As Figure 4 shown, the lifting support rod 3 includes a universal joint 31 provided at the lower end of the top plate 2, a support upper rod 32 connected to the universal joint 31, a support lower rod 34 connected to the base support 4, and a tightening handle 33. The support upper rod 32 and the support lower rod 34 are connected through the tightening handle 33. A rubber plug 35 is provided on the base support 4, and the lower end of the support lower rod 34 is installed on the rubber plug 35.

[0037] Furthermore, the lower end of the support upper rod 32 is sleeved inside the support lower rod 34, and a limiting block 36 for preventing the support upper rod 32 from coming out is provided at the bottom of the support upper rod 32. Through the anti-disengagement limiting block 36 between the support upper rod 32 and the support lower rod 34, it can be ensured that the lifting can be carried out within a certain range without coming out. Similarly, this structure also exists inside the gas spring lifting rod 7 to achieve the same purpose.

[0038] Furthermore, a side rail 8 for hanging surgical instrument accessories is provided on the side of the top plate 2. The setting of the side rail 8 allows medical staff to more effectively organize and access the instruments and accessories required for the operation, improving the operation efficiency and reducing the time for finding tools during the operation.

[0039] Furthermore, a bottom plate 5 is provided on the base support 4, and universal casters 6 are provided at the lower end.

[0040] Furthermore, a bolt 10 is provided at the lower end of the top plate 2. Since the support lower rod 34 and the base support 4 are connected by a rubber plug 35, the support lower rod 34 can be pulled out of the rubber plug 35 and rotated 90° around the universal joint 31 to fix the overall lifting support rod 3 to the lower part of the top plate 2 through the bolt 10 to meet the unobstructed requirement for the entry of the C-arm in special surgical procedures; as Figures 6-7 shown.

[0041] Furthermore, a sponge pad 1 is provided on the upper end surface of the top plate 2. The sponge pad 1 covers the upper end surface of the top plate 2, providing a comfortable lying experience for the patient. The top plate 2 adopts a double concave design, meeting the comfort requirements for doctors to perform microsurgery in a sitting position, with strong hand stability and more accurate microsurgery operation.

[0042] Furthermore, the bottom plate 5 has an ultra-low floor plate design, making the operating table more stable. It can accommodate the doctor's feet and the equipment footrest, and the sitting posture is more comfortable.

[0043] Furthermore, the top plate 2 is made of resin plate or carbon fiber plate, with an X-ray transmissive design, facilitating surgical fluoroscopy. At the same time, there is a sufficient height difference between the top plate 2 and the bottom plate 5 to meet the requirements of the C-arm fluoroscopy equipment during the operation;

[0044] The working principle of the present utility model is as follows:

[0045] During use, first loosen the tightening handle 33, pull the pull rope 75 through the gas spring release rod 9, and then adjust the height of the overall operating table through the gas spring release button 74. It can be lifted and lowered according to the height of the bed to meet the surgical height requirements. After ensuring the height, lock the tightening handle 33. Then spread the sterile cloth on the operating table, loosen the universal caster 6, push it to the operating bed side, and fix the universal caster 6 before performing the operation. If auxiliary instruments or equipment are needed, the relevant equipment can be placed on the bottom plate 5.

[0046] In summary, the present utility model realizes the height adjustment function of the operating table by adopting a combination of gas spring lifting and mechanical lifting support. The gas spring lifting rod 7 is responsible for the lifting on one side, and the lifting support rod 3 is responsible for the lifting on the other side. The two work together to ensure the balance and stability of the operating table during the lifting process.
