The present invention relates to a see-through extension, and more particularly to a see-through extension for an operating table.

According to the general operating table, when performing orthopedic surgery, it is unable to meet the special needs of orthopedics, especially hip to foot surgery. Therefore, an orthopaedic operating table has been developed. However, because the orthopedic operating table has its own particularity, if it is to be applied to general surgery, it is limited by its function and cannot meet the needs.

Therefore, how to make the general operating table and the function of the orthopedic operating table become very necessary, because it can avoid repeated investment and at the same time be more flexible in use. The conventional practice is nothing more than the integration of an orthopedic traction frame to the end of the general operating table. For example, the patent application No. 414077 of the applicant's patent application "Improvement of the operating table connection device" patent (corresponding to the Chinese utility model) Patent No. 99211717.6 makes it possible to integrate a general operating table into a multi-purpose operating table, which is widely used by medical institutions.

However, the skeletal frame of the aforementioned orthopedic traction frame is a metal frame, and the X-ray (X Ray) full-transmission angiography function cannot be performed. Based on the requirement of the pelvic full-transmission angiography, the related industry has developed a perspective extension frame to replace the foregoing. The orthopedic traction frame, the front end of the see-through extension is coupled to the end of the operating table, so that the end of the see-through extension forms a suspended configuration, which is unfavorable for the load. Therefore, the related manufacturer further combines a supporting device at the end of the see-through extension to increase the load capacity of the see-through extension, so that the patient can lie smoothly on the shelf of the see-through extension, The X-ray machine for the 3D C-arm (C-Arm) performs fluoroscopy of the pelvis.

Due to the operation of the handle, it is necessary to turn the hand by the medical staff, failing to comply with the principle of aseptic technique, and easily lead to the risk of cross-infection, which is a drawback.

The main purpose of the present invention is to provide a see-through extension for an operating table, which can be quickly attached to a supporting device at the end of the frame, and the lifting control of the supporting device is not operated by hand to conform to the principle of aseptic technique operation while avoiding crossover. The risk of infection.

In order to achieve the foregoing objectives, the technical means adopted in the present invention is to provide a see-through type extension for an operating table, comprising a frame having a pair of axially parallel and X-ray transparent fixed tubes, Before and after the fixed pipe, a pair of radially parallel front and rear connecting pipes are combined to form a rectangular frame, and a pair of radially extending spanning shafts are arranged outside the front end of the pair of fixed pipes, and the rear connecting pipe is provided a plurality of through holes are formed at an appropriate position on the bottom surface; and a supporting device has a cylindrical hydraulic mechanism mounted on a base, and a plunger inserted into the sleeve hole is protruded from a center of the top of the lifting rod above the hydraulic mechanism, The bottom of the hydraulic mechanism is pivotally connected to a pressure rising pedal and a pressure drop pedal for controlling the lifting rod to be lifted and lowered.
