Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a rotation adjustment mechanism for a surgical operating table. Background Technology

[0002] An operating table (also called an operating table) is an essential tool for doctors during surgery. It is the most important tool for accommodating patients and providing a more convenient surgical environment for doctors. Operating tables are mainly divided into electric operating tables and hydraulic operating tables. They can also be classified according to their purpose, such as multi-functional operating tables, gynecological operating tables, orthopedic operating tables, etc.

[0003] Existing operating tables achieve head-to-leg interchangeability by switching the head and legs, but the bed surface lacks a steering angle adjustment function. This makes the head-to-leg interchange installation cumbersome, limits C-arm imaging at the base, and fails to meet the needs of surgeons.

[0004] Therefore, we propose a rotation adjustment mechanism for a surgical operating table. Utility Model Content

[0005] The present invention aims to solve the technical problems existing in the prior art and provide a rotation adjustment mechanism for a surgical operating table.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rotation adjustment mechanism for a surgical operating table, comprising a base assembly, an automatic rotation adjustment mechanism provided on the upper end of the inner wall of the base assembly, a rotating bed fixedly mounted on the top of the automatic rotation adjustment mechanism, the base assembly including a mounting base, a mounting groove provided at the middle of the top of the mounting base, a limit sliding groove provided on the outer side of the mounting groove at the top of the mounting base, the automatic rotation adjustment mechanism including a gear dustproof box, and the outer wall of the gear dustproof box being fixedly connected to the inner wall of the mounting base at the mounting groove, the inner wall of the gear dustproof box being provided with a self-locking drive mechanism, and the top of the self-locking drive mechanism movably penetrating through the top of the gear dustproof box.

[0007] Preferably, a rotating connecting block is fixedly installed on the top of the self-locking drive mechanism, and the top of the rotating connecting block is fixedly connected to the middle of the bottom of the rotating bed.

[0008] Preferably, connecting rods are uniformly fixedly installed on the lower end of the outer wall of the rotating connecting block, and an installation ring is fixedly installed on the end of the connecting rod away from the rotating connecting block.

[0009] Preferably, the outer wall of the mounting ring is evenly and movably mounted with a limiting roller via a rotating shaft, and the lower end of the outer wall of the limiting roller is movably connected to the inner wall of the mounting base at the limiting groove.

[0010] Preferably, the self-locking drive mechanism includes a servo motor, and the back of the servo motor is fixedly connected to the right side of the front of the gear dustproof box, and the output end of the servo motor moves through the front end of the inner wall of the gear dustproof box.

[0011] Preferably, a worm gear is fixedly installed at the output end of the servo motor, and the back of the worm gear is movably connected to the rear end of the inner wall of the gear dustproof box.

[0012] Preferably, a worm wheel is movably engaged on the left side of the outer wall of the worm.

[0013] Preferably, a rotating shaft is fixedly installed on the inner wall of the worm gear, and the bottom of the rotating shaft is movably connected to the bottom of the inner wall of the gear dustproof box.

[0014] Preferably, the top of the rotating shaft extends movably through the top of the gear dustproof box, and the top of the rotating shaft is fixedly connected to the bottom of the rotating connecting block.

[0015] This invention provides a rotation adjustment mechanism for a surgical operating table. It has the following beneficial effects:

[0016] 1. The rotation adjustment mechanism of this surgical operating table is equipped with an automatic rotation adjustment mechanism. During use, a servo motor drives a worm gear to rotate, which in turn drives a worm wheel to rotate. The worm wheel drives a rotating shaft to rotate, which in turn drives a rotating connecting block to rotate. The rotating connecting block then drives the rotating table to rotate and adjust, allowing for head-to-tail interchange without rotating or disassembling the entire device. This facilitates X-ray imaging. Limiting rollers and limiting slides can limit the rotation of the table, preventing it from shifting during rotation.

[0017] 2. The rotation adjustment mechanism of this surgical operating table, by setting a self-locking drive mechanism, ensures the stability and accuracy of transmission after the worm gear is driven to rotate by a servo motor. This makes the rotation adjustment of the operating table more stable and reliable. The design of the self-locking drive mechanism can also realize the automatic locking function of the operating table. When the servo motor stops working, the meshing of the worm gear and worm wheel can prevent the operating table from rotating accidentally due to external forces, thereby ensuring the safety and stability of the operating table.

[0018] 3. The rotation adjustment mechanism of this surgical operating table, by setting up a gear dustproof box, can protect the worm gear and worm wheel from dust, avoid dust affecting the operation of the worm gear and worm wheel, and improve the service life of the rotation adjustment mechanism of this surgical operating table.
