Direction adjusting equipment accessory applied in medical treatment field

Abstract

The invention belongs to the technical field of medical instrument universal rotation, and particularly relates to a direction adjusting equipment accessory applied in the medical treatment field. Thedirection adjusting equipment accessory applied in the medical treatment field comprises a first connecting rod, a second connecting rod and a hydraulic cylinder. A universal joint device has all functions of a spherical hinge, and compared with a traditional spherical hinge, the device has the advantages that relative swinging and rotating between the first connecting rod and the second connecting rod can be controlled by controlling a switching valve between a second liquid pipe and an elastic liquid sac, and then the first connecting rod and the second connecting rod achieve the self-locking function. According to the direction adjusting equipment accessory applied in the medical treatment field, when a piston rod rotates relative to a piston shell, the limiting effect on a limiting plate installed on the piston rod is achieved through a clamping plate installed on the upper end face of a sleeve of a piston column, the rotation angle is smaller than 360 degrees, the condition thatin the process that the piston rod rotates relative to a piston inner shell, an inner thread formed in a threaded sleeve installed on the piston inner shell is separated from an outer thread formed inthe piston rod, and the safety of the device is improved.

Description

[0001] Technical field [0002] The invention belongs to the technical field of universal rotation of medical equipment, and in particular relates to a direction adjustment equipment accessory in the medical field. Background technique [0003] In the existing medical field, the use of a stent with a universal function to control the spatial position requires multiple hinges to realize. If it is realized simply by using two-dimensional hinges, multiple two-dimensional articulated devices are required, which will cause the structure of the stent to be complicated. control, and it is cumbersome to operate. If the ball joint is used to connect, only a few ball joints are needed to realize the ball joint. The structure of the ball joint is simple, the operation is convenient, and it is easy to control; In the process, the ball joint needs to be self-locked, so it is very necessary to design a self-locking ball joint for the bracket in the medical field. [0004] The invention des...
