Description

Technical Field

[0001] This utility model belongs to the field of medical devices and relates to a universal fixing lock for operating tables. Background Technology

[0002] Depending on the surgical needs, patients require different surgical positions during the operation. These positions necessitate the use of different positioning brackets, which are connected to the operating table via locking mechanisms. Different brands of operating tables have varying specifications and bracket models, meaning that positioning brackets from different brands (including imported, joint-venture, and domestic) can only be paired with the same brand of locking mechanism. This causes significant inconvenience in clinical management and use. In particular, a malfunction of the brand-specific locking mechanism renders the positioning bracket unusable, resulting in unsatisfactory positioning, impacting patient safety and work efficiency.

[0003] The existing Chinese utility model patent with announcement number CN202236115U is a universal operating table bracket fixing lock, which includes a lock body and a spiral top rod. The fixing lock has a side rail groove with a hook edge on the end face of the lock body. The lock body has a rod fixing hole for adjusting the tightness by means of the spiral top rod. The rod fixing hole extends towards the end face to form an extension hole edge for fixing the lock body by means of the rod.

[0004] The existing technology has the following technical defects:

[0005] The fixed lock has only one type of mounting slot. To accommodate different types of accessory connection sections, two different types of fixed locks for accessory connection sections must be equipped, which is cumbersome in actual use. Furthermore, the installation dimensions are fixed, and the side rail slot can only accommodate a single type of side rail, making it incompatible with different bed types. Secondly, although the fixed lock can be adapted to different specifications of operating tables, it is fixed to the side rail by the fixed lock hook. For side rails of different thicknesses, the reserved space of the fixed lock determines whether the two are tightly fixed. For side rails of different thicknesses, there will be wobbling. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a universal fixing lock for operating tables.

[0007] The universal operating table locking device of this utility model includes a side rail bracket, on which a locking post with a central through-hole is fixedly connected. A pressing rod with a threaded connection to the top of the locking post is threaded through the top of the post. A handle is connected to the top of the pressing rod. A pressing base and a connecting section lock housing are sequentially fitted around the locking post. The connecting section lock housing is provided with a circular mounting groove and a rectangular mounting groove. The bottom of the connecting section lock housing abuts against the top of the pressing base. A pressing block is provided on the pressing base. A sliding groove adapted to the pressing block is provided on the side rail bracket.

[0008] Working process or working principle:

[0009] In use, the edge rail clamping seat is clamped on the edge rail of the operating bed, the body position support connecting section has a circular shape and a rectangular shape, the connecting section lock shell is rotated to align the corresponding installation slot with the middle through hole of the locking column, the body position support connecting section is inserted into the installation slot, after the position is adjusted, the rotating handle is rotated to move the pressing rod downward and press the connecting section, the connecting section is pressed to move the connecting section lock shell downward and press the pressing base, the pressing block of the pressing base is in contact with the edge rail of the operating bed and gradually increases the pressing force, so that the fixing is completed.

[0010] The locking column is fixedly connected with the edge rail clamping seat through bolts.

[0011] The edge rail clamping seat is provided with a one-side opening, and the one-side opening facilitates quick mounting and dismounting of the edge rail of the operating bed.

[0012] The working surface of the edge rail clamping seat is provided with a chamfer, so that there is no gap after being locked with the edge rail of the operating bed, and the generation of shaking is prevented.

[0013] The end, at which the pressing base and the connecting section lock shell abut, is provided with corresponding connecting teeth, and the connecting section lock shell can be quickly switched to the through hole matched with the connecting section by separating the teeth.

[0014] The pressing rod is hinged with the handle, so that the use is facilitated.

[0015] Compared with the prior art, the utility model has the beneficial effects that:

[0016] At present, the size and thickness of the edge rail of the operating bed of different brands on the market are 8-10mm, and the width is 24-30mm, the edge rail clamping seat of the utility model is provided with a side opening, the opening is larger, and the installation space is larger, and the edge rail of the operating bed in the above size range can be matched. The utility model is quickly connected with the edge rail of the operating bed, without any additional fixing measures, the operation is more convenient and fast, and the locking mechanism has two different installation slots, which is matched with various accessories, including the cylindrical connecting section accessories and the rectangular connecting section accessories with a diameter of less than 20mm.
