Abstract

The invention discloses a composite polytetrafluoroethylene material for a guide sleeve framework in an operating table hydraulic system. The system comprises a first hydraulic oil cylinder and a second hydraulic oil cylinder which are installed with a first hip plate and a second hip plate in a matched mode, a first piston of the first hydraulic oil cylinder divides a first cylinder body into a cavity and a cavity b, and a second piston of the second hydraulic oil cylinder divides a second cylinder body into a cavity c and a cavity d; the cavity c is communicated with the cavity a, a first oil compensating pipe is arranged on the end face, provided with the first piston, of the first cylinder body, and a first control valve is arranged on the first oil compensating pipe. The technical purpose of providing the hydraulic system, achieving oil compensation, of an operating table is achieved, and the hydraulic system can make the first piston rod and the second piston rod of the hip plates of the operation table move more accurately and synchronously.

Description

[0001] This case is a divisional application, the application number of the parent case is 2016108285361, and the filing date is 20160919. technical field [0002] The invention relates to the field of operating tables, in particular to a hydraulic system of an operating table. Background technique [0003] The column longitudinally offset operating table can meet the body position requirements that ordinary operating tables cannot meet, and can realize the detection of the patient's whole body. [0004] In the process of adjusting the buttock plate of the existing operating table, due to the influence of the manufacturing accuracy and the wear of the seal after a long period of use, the oil leaks slowly, and the oil flows on both sides of the piston, making it difficult to achieve synchronous adjustment , causing the operating table to need frequent maintenance, causing too much inconvenience to the user, and also making the maintenance cost too high.
