Description

Technical Field

[0001] The utility model relates to the technical field of an arm tube for an instrument clamping table and an instrument clamping table, in particular to an arm tube for an instrument clamping table. Background Art

[0002] In surgical operations, since a large number of surgical instruments or materials required for the operation are needed, a surgical instrument table for holding these surgical instruments and materials needs to be set up next to the operating bed. The purpose of setting up the surgical instrument table is to facilitate doctors to replace surgical instruments and use materials required for the operation during the operation.

[0003] During surgical operations, patients often need to be anesthetized. In practice, many patients swing their arms wildly and are difficult to control after anesthesia, causing obvious interference to the surgeons nearby, which poses a great safety hazard. The existing practice is to wrap the arms with cloth and ropes and tie them to the bedside. This practice is inconvenient, unprofessional, and has poor fixation effect. Most of the current surgical bed instrument tables, such as solutions CN209629831U and CN210056235U, are mainly used to place surgical instruments and lack the function of fixing the arms.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is an arm tube for an instrument clamping table: it includes an arm tube and a lifting clamping plate, the arm tube is used to put on the arm, the lifting clamping plate is vertically arranged and has a wavy clamping surface; elastic wheels are provided at both ends of the arm tube on the side, the elastic wheels slide up and down along the wavy clamping surface, and the arm tube is clamped and fixed between the two lifting clamping plates and can move up and down.

[0006] As an improvement, the elastic wheel includes a V-shaped wheel frame and rollers at both ends thereof, and the V-shaped wheel frame can be elastically expanded.

[0007] As an improvement, the V-shaped wheel frame is rotatably connected to the crossbeam of the arm tube.

[0008] As an improvement, the V-shaped wheel frame is a metal frame, and the V-shaped angle is an obtuse angle.

[0009] As an improvement, the wave-shaped clamping surface includes a plurality of adjacent arc-shaped concave surfaces, and the arc-shaped concave surfaces can clamp the elastic wheel.

[0010] The instrument fixture table of the utility model includes the arm tube described in any technical scheme of the utility model, the lifting and lowering positioning plate serves as a part of the support rod of the instrument fixture table, the bottom of the support rod is provided with casters, there are four support rods and two arm tubes, which are symmetrically arranged, and the arm tube is located at the lower part of the instrument fixture table.

[0011] The advantages of the utility model compared with the prior art are: when the two lifting and clamping plates are fixed in the vertical position, the arm tube is pushed up or down with force, and the elastic wheel slides along the wave-like clamping surface, and the arm tube can move up and down between the two lifting and clamping plates. When the roller leaves the arc-shaped concave surface, the V-shaped wheel frame is stretched open, and when the roller enters the arc-shaped concave surface, the V-shaped wheel frame is restored. At this time, the roller is stuck and the height of the elastic wheel is fixed, thereby achieving fixed support for the arm tube. The patient lies on the operating bed, and various instruments are placed on the upper part of the instrument card table, and then placed on the upper part of the operating bed and the patient. Adjust the two arm tubes to the height of the arm, and then move the instrument card table so that both arms are inserted into the corresponding arm tubes. The casters can be positioned, and then the doctor can perform surgery-related operations.

[0012] The arm tube for the instrument card table is designed on the instrument card table of the operating table. It has a very good function of fixing the arm, preventing the patient's arm from swinging randomly to interfere with the surgeon. It is easy to use and has high practical value and promotion value.
