Problems solved by technology

[0003] In the existing medical field, it is necessary to use multiple hinges to realize the support with universal function and to control the spatial position. If it is realized simply by using two-dimensional hinges, multiple two-dimensional hinge devices are required, which will cause the structure of the support to be complicated. , and it is not easy to control, and it is troublesome to operate. If the ball joint is used to connect, only a few ball joints are needed, and the structure of the ball joint is simple, easy to operate, and easy to control; if the ball joint is used in the medical field , the ball joint needs to be self-locked during use, so it is necessary to design a self-locking ball joint for brackets in the medical field

Abstract

The invention belongs to the technical field of universal rotation of medical instruments, and particularly relates to a support self-locking device in the medical field. The support self-locking device comprises a first hinged rod, a second hinged rod and piston-type hydraulic cylinders, wherein the support self-locking device, as a universal joint device, has all functions of a spherical hinge;and compared with a traditional spherical hinge, a switch valve between a second pipeline and an elastic liquid bag can be controlled to control the relative swing and rotation between the first hinged rod and the second hinged rod so as to enable the first hinged rod and the second hinged rod to achieve a self-locking function. If the device is applied to a support in the medical field, comparedwith a traditional support which is used by matching the two-dimensional hinge and the universal hinge, the support is simpler to operate and easy to control, and the working efficiency of workers isimproved; and according to the device, the same elastic liquid bag can be used for the plurality of piston-type hydraulic cylinders, that is, the self-locking of a plurality of hinge points can be simultaneously controlled by controlling a switch of one liquid bag.

Description

[0001] Technical field [0002] The invention belongs to the technical field of universal rotation of medical equipment, and in particular relates to a bracket self-locking device in the medical field. Background technique [0003] In the existing medical field, it is necessary to use multiple hinges to realize the support with universal function and to control the spatial position. If it is realized simply by using two-dimensional hinges, multiple two-dimensional hinge devices are required, which will cause the structure of the support to be complicated. , and it is not easy to control, and it is troublesome to operate. If the ball joint is used to connect, only a few ball joints are needed, and the structure of the ball joint is simple, easy to operate, and easy to control; if the ball joint is used in the medical field , the ball joint needs to be self-locked during use, so it is very necessary to design a self-locking ball joint for brackets in the medical field.
