Description

Technical Field

[0001] This utility model relates to the field of interventional surgery assistance technology, specifically an auxiliary fixation device for interventional surgery. Background Technology

[0002] Interventional radiology, also known as interventional therapy, is an emerging clinical discipline and an important component of minimally invasive medicine. It is considered the third major clinical discipline, independent of traditional internal medicine and surgery. Without incisions to expose the lesion, it utilizes advanced imaging equipment (such as DSA, ultrasound, and CT) to create tiny channels (a few millimeters in diameter) in the skin or through existing body cavities. Specialized needles and catheters are then inserted into the diseased organ or tissue to directly inject drugs, embolic agents, or place stents to treat various diseases. In actual surgical procedures, the operating tables used in interventional radiology are typically relatively narrow. This design feature can lead to challenges for patients during the procedure. Inevitably, the patient's hand will naturally droop to the edge of the bed. Given that interventional surgeries often require a long operation time, patients are prone to discomfort and fatigue if they maintain this drooping arm position for an extended period. To optimize the patient's surgical experience and improve their comfort during treatment, medical staff will take professional measures to properly fix the patient's arm on one side. This also facilitates intravenous puncture in that arm for intravenous infusion, medication administration, or connection of various monitoring devices to monitor the patient's vital signs in real time. More importantly, it effectively restricts the patient's unconscious hand movements, avoiding surgical risks or interference that may be caused by random hand movements, while also allowing the patient to receive treatment in a more stable and comfortable posture.

[0003] Currently, when immobilizing a patient's arm, the common method is to wrap and tighten the arm with a strap to secure it to the positioning plate. However, this method, which requires careful wrapping and tightening, is quite cumbersome, affecting not only the ease of operation but also reducing its practicality to some extent. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary fixation device for interventional surgery to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary fixation device for interventional surgery, including a bed body, a sliding groove inside the bed body, a positioning plate slidably connected inside the sliding groove, a plurality of symmetrically arranged straps fixedly connected to the positioning plate, a mattress placed on the top of the bed body, and a pad placed on the top of the positioning plate.

[0006] The positioning plate is provided with a tightening mechanism, which includes two mounting slots and two limiting slots. A rotating rod is rotatably connected inside each mounting slot. A gathering roller is fixedly connected to each rotating rod. A connecting rod is slidably connected to one end of each rotating rod. A limiting ring is fixedly connected to one end of each connecting rod.

[0007] Preferably, the mounting grooves are symmetrically formed inside the positioning plate, and the limiting grooves are symmetrically formed on one side of the positioning plate.

[0008] Preferably, the mounting grooves are all in communication with the corresponding limiting grooves, and one end of each strap slides through the top wall of the positioning plate and is fixedly connected to the corresponding gathering roller.

[0009] Preferably, the linkage rod is square in shape, and the limiting rings are all slidably connected inside the corresponding limiting grooves.

[0010] Preferably, symmetrically arranged handles are fixedly connected to the positioning plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: simply remove the limiting ring from the limiting groove, and then drive the gathering roller to rotate by rotating the limiting ring. As the gathering roller rotates, the straps will be effectively gathered and tightened, thereby achieving a firm fixation of the patient's arm. After the strap tightening operation is completed, simply reset the limiting ring back into the limiting groove to easily complete the entire fixation process. This method is not only simple and quick to operate, but also can tighten two straps at the same time, greatly improving practicality and efficiency. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 The present invention provides the following technical solution:

[0019] Example 1: An auxiliary fixation device for interventional surgery includes a bed body 1, a sliding groove 2 inside the bed body 1, a positioning plate 3 slidably connected inside the sliding groove 2, a plurality of symmetrically arranged straps 4 fixedly connected to the positioning plate 3, a mattress 5 placed at the top of the bed body 1, a pad 6 placed at the top of the positioning plate 3, and symmetrically arranged pull handles 8 fixedly connected to the positioning plate 3.

[0020] When in use, the positioning plate 3 can be pulled out of the slide groove 2 by the handle 8. After being pulled out to a suitable distance, the pad 6 can be placed on the positioning plate 3 through the two straps 4, and then the patient's arm can be wrapped and fixed by the straps 4.

[0021] Example 2: The technical solution of this example that differs from that of Example 1 includes: a tightening mechanism 7 is provided on the positioning plate 3. The tightening mechanism 7 includes two mounting grooves 71 and two limiting grooves 72. A rotating rod 73 is rotatably connected inside each mounting groove 71. A gathering roller 74 is fixedly connected to each rotating rod 73. A connecting rod 75 is slidably connected to one end of each rotating rod 73. A limiting ring 76 is fixedly connected to one end of each connecting rod 75.

[0022] The mounting grooves 71 are symmetrically opened inside the positioning plate 3, and the limiting grooves 72 are symmetrically opened on one side of the positioning plate 3. The mounting grooves 71 are all in communication with the corresponding limiting grooves 72. One end of the strap 4 slides through the top wall of the positioning plate 3 and is fixedly connected to the corresponding gathering roller 74. The linkage rod 75 is square in shape, and the limiting rings 76 are all slidably connected inside the corresponding limiting grooves 72.

[0023] In use, the patient's arm can be placed on the pad 6 on the positioning plate 3, and the patient's arm can be passed through the two straps 4. At this time, the limiting ring 76 can be pulled out of the limiting groove 72. The movement of the limiting ring 76 will cause the connecting rod 75 to extend out of the rotating rod 73. When the limiting ring 76 is separated from the limiting groove 72, the limiting ring 76 can be rotated directly. The rotation of the limiting ring 76 will cause the connecting rod 75 to rotate together. Since the connecting rod 75 is square, the rotation of the connecting rod 75 will cause the rotating rod 73 to rotate together. The rotation of the rotating rod 73 will cause the gathering roller 74 to rotate. The rotation of the gathering roller 74 will roll up the straps 4. At this time, the straps 4 will be wrapped around the gathering roller 74. The tightened straps 4 will fix the patient's arm on the pad 6. Then, the limiting ring 76 can be returned to the limiting groove 72 to complete the operation. The operation is very convenient.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
