Connecting structure for seat plate and leg plate of operating table

Abstract

The invention relates to a connecting structure for a seat plate and a leg plate of an operating table, which comprises a seat plate and a leg plate interface, wherein the seat plate is connected with the leg plate interface by a rotating shaft, and the rotating shaft is provided with a locking device; the upper end of the leg plate interface is connected with the seat plate by a screw, and the lower end is connected with the seat plate by the rotating shaft; the rotating shaft is fixedly connected with the leg plate interface by a leg plate fixing pin; the locking device comprises a leg plate interface spline gear, a seat plate spline gear and a handle, the leg plate interface spline gear is arranged below the leg plate interface, the seat plate spline gear is fixedly connected with the seat plate at a position corresponding to the leg plate interface spline gear, the handle is arranged below the seat plate, and the handle is in threaded connection with the rotating shaft; and the leg plate spline gear and the seat plate spline gear are respectively fixedly connected with the leg plate interface and the seat plate by a locking spline gear fixing pin. By using the structure, the leg plate can be bent downwards or outwards and can be locked at any position, thereby facilitating doctors to select the stance. Besides, the invention lowers the maintenance cost, thereby greatly relieving the burden of hospitals on operating table maintenance.

Description

technical field [0001] The invention relates to an operating bed in the medical device industry, in particular to a connection structure between a seat board and a leg board of the operating bed. Background technique [0002] The operating bed is an essential auxiliary tool for the surgical operation and diagnosis of various parts of the human body in the operating room of the hospital. There are two types of connection between the seat board and the leg board of the operating table: 1. The leg board interface is directly fixed on the seat board In this way, the leg board cannot be rotated outward; 2. The connection between the leg board and the seat board is provided with a small locking gear, which makes it difficult to lock the leg board conveniently and quickly. Both of the above two design forms have the same disadvantage: once the leg plate interface is damaged, it will be required to replace the whole set of seat plate, and the material cost and maintenance cost will ...

[0002]The operating bed is an essential auxiliary tool for the surgical operation and diagnosis of various parts of the human body in the operating room of the hospital. Two forms: 1. The leg board interface is directly fixed on the seat board. In this way, the leg board cannot be rotated outward; 2. The connection between the leg board and the seat board is equipped with a small locking gear, which makes it difficult to Easy and fast locking leg plate

The above two design forms have the same disadvantages: once the leg plate interface is damaged, it will be required to replace the entire seat plate, and the material cost and maintenance cost will increase greatly
