Description

Technical Field

[0001] This utility model relates to the field of hand surgery positioning fixation, specifically a limb surgery positioning fixation table. Background Technology

[0002] Current limb surgery positioning and immobilization tables are typically replantation surgery immobilization tables, which are made of metal. During operation, bleeding and irrigation of the surgical field often lead to blood and water accumulation on the table, making it difficult to collect and drain the accumulated blood and irrigation fluid. This easily causes the table surface to become wet, contaminating the surgical field. To keep the table surface dry, surgical drapes need to be changed, or the hand needs to be removed from the immobilization table and repositioned during irrigation, affecting surgical time and causing inconvenience. Moreover, current devices can only maintain the hand in a single plane during surgery, limiting the possible positions. Many special positions require assistants, resulting in wasted personnel. Furthermore, hand surgeries often use microsurgical sutures of 9-0 or higher. Frequent changes in drapes or positioning during surgery can easily lead to suture loss, posing surgical risks. Additionally, for foot surgeries, traction ropes are needed. After traction, the ropes are usually fixed on both sides. Adjusting the tension after fixation requires reopening the fixation, which is cumbersome. Therefore, how to facilitate the drainage of wastewater after irrigation while also allowing for adjustment of the rope position after fixation is a problem that urgently needs to be solved by technicians in this field. Utility Model Content

[0003] The purpose of this invention is to provide a limb surgical positioning fixation table to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a limb surgical positioning and fixation table, comprising a square shell, the top left end of which is tilted to the right to facilitate limb placement, and a drain pipe connected to the bottom of the shell. The top and left ends of the shell are open, and a support mechanism with permeable holes for supporting the limb is inserted into each opening. The table also includes a fixing mechanism for fixing the limb at the front and rear ends of the shell. A sliding mechanism for fixing pull ropes at the front and rear ends is also included, which can slide left and right and then be fixed to adjust the position of the pull ropes.

[0005] Preferably, the fixing mechanism includes a sliding mechanism for fixing the foot pull rope. The sliding mechanism can slide left and right and then be fixed to adjust the fixed position of the pull rope. The sliding mechanism can slide left and right to adjust the position and realize the adjustment of the tension of the pull rope. It also includes a finger fixator that is detachably installed on the support mechanism for fixing the fingers. It is used to fix the hand and fix the fingers, and is detachable.

[0006] Preferably, the support mechanism includes a tray with a shape adapted to the opening of the shell. The tray has support plates at both its front and rear ends that abut against the bottom of the shell's inner cavity, and water-permeable holes are evenly distributed on the support plates. The shell, tray, and support plates are all made of stainless steel for easy sterilization. Note that although the left end of the shell is open, a vertical distance is left to prevent waste liquid from spilling out, providing a certain storage effect so that it can be discharged through the drain pipe.

[0007] Preferably, the sliding mechanism includes two guide rails mounted on the front and rear ends of the housing, arranged left and right, and a slider sleeved on the guide rails. The slider is equipped with a hook for fixing a pull rope. It also includes a locking mechanism between the slider and the guide rails to achieve fixed adjustment. The slider slides along the guide rails to adjust its fixed position, and the locking mechanism secures the slider after adjustment.

[0008] Preferably, the locking mechanism includes a stop rod inserted into one of the opposite ends of the two sliders, and a pull block is provided at the end of the stop rod. The guide rail has equally spaced slots corresponding to the stop rods, and the pull block is connected to the slider by a spring sleeved on the stop rod. Under the action of the spring, the stop rod engages with the slot to achieve fixation. When the position needs to be adjusted, the stop rod can be pulled out directly to slide left or right, thus eliminating the need for a pull rope on the hook, making it more convenient.

[0009] Preferably, the stop rod has a square cross-section, and the shape of the slot corresponds to the stop rod. The pull block is a flat plate, and the pull block has multiple gaps to facilitate the insertion of the rope. Here, the rope can be directly wound around the gaps on the pull block.

[0010] Preferably, the finger retainer includes multiple inverted "U"-shaped retaining rings installed on the water-permeable holes, and the lower end of the retaining ring is connected with a nut to achieve a detachable connection, allowing the finger to be inserted into the retaining ring.

[0011] Preferably, the tray is an arc shape with a concave center and convex sides, which makes it easy to place the legs or arms and prevents them from sliding back and forth.

[0012] Preferably, the upper right side of the housing is provided with a slot for easily fastening the tray.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Place your feet on the support plate and your lower legs on the left side of the support plate. Tie the rope into a loop and attach it to the hook. When you need to adjust the position, pull the pull block. The stop bar will slide out of the slot, and you can slide left or right to adjust the position without having to untie the rope. It is simple and convenient.

[0015] 2. The pull block has gaps, which can also be used to directly lock and fix the rope. Simply pull the rope back and wrap it around the gaps to secure it.

[0016] 3. The retaining ring makes it easy to secure the fingers of the hand, and it is detachable, easy to adjust the position, and flexible in use. Attached Figure Description
