Description

Adjustable upper limb universal fixation frame for operating table

Technical field

The utility model relates to a medical instrument, in particular to an adjustable upper limb universal fixation frame for an operating bed.

Background technique

Spine endoscopy and other surgeries are routine minimally invasive surgeries for the treatment of lumbar disc herniation and spinal stenosis. In recent years, due to the continuous development of surgical technology and endoscopic instruments, posterior lumbar decompression and fusion surgeries have gradually become minimally invasive, Endoscopy.

During endoscopic posterior lumbar decompression and fusion surgery, the patient is usually positioned prone, with both upper limbs placed on the rectangular handrests on both sides of the operating bed, and the vertebral body is positioned before the operation, and the vertebral body is positioned during the operation. The skin is implanted with positioning guide wires, pedicle screw rods and fusion cages under the microscope, and the implants are reconfirmed after surgery. Since the G-arm needs to be used for intraoperative fluoroscopy during these critical periods before, during and after surgery, the G-arm needs to move back and forth on the operating bed during the fluoroscopy process in order not to affect the surgical process. At this time, the operating bed is used The conventionally configured rectangular armrest has the following disadvantages: (1) Since the conventional armrest is large in size and takes up a lot of space, and the surgical space is fixed, on the one hand, the obstruction of the conventional armrest will greatly hinder the movement of the G-arm. The speed of movement leads to prolonged operation time. On the other hand, the obstruction of the conventional armrest will continuously adjust the height of the operating table during the fluoroscopy process, thereby increasing the number of fluoroscopy; (2) Since the conventional armrests are fixed on both sides of the operating bed, , the angle of the upper limbs of patients with different body types cannot be adjusted at will, which affects the control of the G-arm; (3) Because the conventional arm rest takes up a large space, the G-arm working space is small, and the G-arm will move when moving in a small space. It causes compression to the patient's elbow, causing damage to the nerves in the elbow and pressure injuries to the skin of both upper limbs.

Utility model content

The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide an adjustable upper limb universal fixation frame for an operating bed, which is small in size, takes up little space, can reduce the number of intraoperative fluoroscopy and shorten the operation time, and The angle can be adjusted at will, which is convenient for G-arm control and can avoid nerve damage in the elbow and pressure damage to the skin of both upper limbs.

In order to solve the above technical problems, the utility model adopts such an adjustable upper limb universal fixator for operating beds, which includes a C-shaped supporting plate, a universal ball joint and a support plate. The universal ball joint includes a universal ball. and a ball seat and a set screw. The universal ball is sleeved in the ball seat. The set screw is threadedly connected to the ball seat. A connecting rod is arranged vertically above the universal ball. The lower end of the connecting rod is fixedly connected to the top of the universal ball, the upper end of the connecting rod is fixedly connected to the bottom of the C-shaped support plate, and a vertically arranged sliding rod is provided below the ball seat, and the upper part of the sliding rod is The cylindrical section and the lower part are threaded sections, and the upper end of the sliding rod is fixedly connected to the bottom of the ball seat; the support plate consists of a horizontal plate arranged along the length direction of the operating bed, a transverse plate arranged along the width direction of the operating bed, and a horizontal plate arranged along the height direction of the operating bed. The arrangement is composed of vertical plates, a first opening slot is opened along the length direction on the horizontal plate, a second opening slot is opened along the length direction on the transverse plate, and a second opening slot is opened along the length direction on the vertical plate. There is a third open groove, the first open groove is connected with the second open groove, the cylindrical section of the sliding rod is placed in the first open groove and the second open groove, and the cylindrical section is connected with the first open groove and the second open groove. The second open slot is slidingly connected. The threaded section of the sliding rod is placed under the first open slot and the second open slot and is threadedly connected to the fastening nut. The support plate is connected to the support plate through bolts passing through the third open slot. The operating table is fixedly connected.
