Description

Technical Field

[0001] The utility model relates to the technical field of instrument racks, in particular to a gastrointestinal surgical instrument rack. Background Art

[0002] A gastrointestinal surgical instrument rack is a device for supporting and fixing instruments and equipment required in surgical operations. Publication No. CN 213963643 U discloses a gastrointestinal surgical instrument rack. The gastrointestinal surgical instrument rack described in the utility model can change the distance between the limiting main rod and the limiting auxiliary rod, so as to fix instrument trays of different sizes, and has a wider range of uses. The instrument tray is fixed between the movable part and the fixed part, and the limiting main rod and the limiting auxiliary rod are in contact with the surface of the instrument tray, which can improve the stability of the instrument tray and bring better prospects for use.

[0003] When the above-mentioned prior art is in use, "the instrument tray is placed on the support rod and the supporting sub-rod by pulling the movable part, the movable part is released, the automatic reel is started, the movable part is driven to move, and the instrument tray is clamped". This type of fixation of the instrument tray relies on the resistance force of the movable part to clamp and fix the front and back sides of the instrument tray. The left and right sides of the instrument tray are not constrained, and its stability is poor. Moreover, when the width of the instrument tray is much larger than the distance between the two groups of support rods, after placing the instrument on the inner instrument tray, if the instrument is unevenly distributed in the instrument tray, causing the center of gravity to be closer to the left or right side, its stability is even worse. Utility Model Content

[0005] In view of this, the purpose of the utility model is to propose a gastrointestinal surgical instrument rack, and the technical problem to be solved is a method of clamping and fixing the front and rear sides of the instrument tray using movable parts. When the instruments are placed on the inner instrument tray, if the instruments are unevenly distributed in the instrument tray, causing the center of gravity to be closer to the left or right side, then its stability will be worse.

[0006] (II) Technical solution

[0014] Preferably, a threaded rod is rotatably connected to the top of the second toothed plate via a bearing, and the threaded rod passes through the second hollow plate and is threadedly connected to the second hollow plate.

[0015] It can be seen from the above technical solutions that the present application has the following beneficial effects:

[0016] 1: Put down the instrument tray so that the cylindrical rod passes through the round hole, then pull the connecting plate and turn it over, rotate the connecting plate and the positioning rod to be above the moving rod, and make the positioning rod and the positioning hole face each other, then stop pulling the moving rod. At this time, the positioning rod is driven to be embedded in the positioning hole under the spring rebound force, that is, the side plate is fixed on the cylindrical rod. This installation method is more stable.

[0017] 2: Rotate the bidirectional screw to drive the two cylindrical rods on the same cylinder to move closer to or away from each other, and then rotate the threaded rod to drive the second tooth plate to move up. When the second tooth plate is separated from the first tooth plate, the first tooth plate is moved to make the cylindrical rods on different cylinders move closer to or away from each other, so that the device can fix instrument trays of different sizes.
