Description

TECHNICAL FIELD

[0001] The utility model relates to surgical bed technical field more specifically, it is a surgical bed with trundle lifting structure. BACKGROUND

[0002] In prior art, surgical bed as patient support equipment is the key equipment indispensable for normal operation, and the common structure of surgical bed is as shown in the figure, which comprises a bed body 01, a base 03 and a stand 02 for connecting the bed body 01 and the base 03. Figure 1 During operation, the surgical bed must be reliably locked and stable and reliable, so as to provide solid support for operation, therefore, the base 03 of the surgical bed needs to provide a large enough support plane, and the support plane of the base 03 must be in contact with the ground when locked.

[0003] At present, the locking modes of surgical bed mainly include: 1, central control trundle 04, that is, the trundle 04 itself can be adjusted to the locking position to realize the locking of the bed body 01, but due to the limitation of its own structure, this locking mode is not firm enough, and is only used in places where the stability requirement of the bed body 01 is not high; 2, brake column fixed type, that is, the base 03 is lifted by a separate brake column, so that the trundle 04 is separated from the ground, the brake column can be mechanically controlled or driven by electricity, but the stability of this structure needs to be improved, only when the brake column contacts the ground, the base 03 is suspended as a whole, the brake column is easy to be damaged after long time use, and the ground structure of the operating room is easy to be damaged due to the small contact area of the brake column; 3, base landing type, that is, the trundle 04 is made into a lifting structure, the trundle 04 is extended to contact the ground during movement, and the trundle 04 is retracted into the base 03 during locking, and the base 03 falls back to the ground as a whole, this structure is more stable during locking, and has a large contact area with the ground, so it is not easy to damage the ground.

[0004] The common base landing type structure is as shown in the figure, the trundle 04 is fixed on the mounting plate 07, and the mounting plate 07 can move relative to the base 03. Figure 2 The position of the trundle 04 and the mounting plate 07 is fixed by the guide pin 06, and the trundle 04 can only move in the vertical direction. The driving structure 05 is vertically fixed on the base 03 and has the function of axial extension and retraction, so that the distance between the trundle 04 and the mounting plate 07 and the base 03 can be controlled by the extension and retraction of the driving structure 05, that is, the trundle 04 can be extended from the base 03 or retracted into the base 03. In order to ensure the convenience of moving the surgical bed, the trundle 04 needs to be as large as possible, but in the operation of taking pictures and perspective, the overall height of the base 03 cannot be too high in order to ensure the use of C-arm during operation, otherwise the picture taking equipment will be interfered.

[0005] However, the driving structure 05 of the existing structure overlaps with the caster 04 and the mounting plate 07 in the vertical direction, which makes it difficult to compress the overall height of the base 03, resulting in the problem that the overall height of the base 03 is too high to meet the use requirements. Some manufacturers avoid this problem by making a step on the top of the base 03, that is, only locally higher at the caster 04, and lower outside the caster 04, but cannot completely avoid the existence of high points, and there is still a risk of collision in use. At the same time, the existence of the step surface is not conducive to daily cleaning and disinfection, and may increase the risk of infection in the operating room.

[0006] In summary, how to provide a lifting structure that is convenient to realize the lifting movement of the caster and can make the overall structure of the base compact and avoid mutual collision and interference with the radiographic equipment is a problem that needs to be solved by the technical personnel in the field at present.
