Technical Field
[0001] The utility model relates to the technical field of puncture body position fixing, in particular to a bone marrow puncture body position fixing device. Background Art
[0002] Bone marrow aspiration is a commonly used diagnostic and treatment technique in clinical practice, particularly important in the diagnosis of hematological disorders and tumors. The procedure requires the patient to maintain a specific position, typically in the lateral position, to ensure accurate and safe entry of the needle into the bone marrow cavity. However, maintaining patient positioning during the procedure often presents numerous challenges, particularly in elderly and frail patients.
[0003] Traditionally, patients undergoing bone marrow aspiration are usually placed on a regular operating table and fixed in position using a rigid fixator or strap. This fixation method has several significant problems:
[0004] Unstable fixation: When using bandages or rigid fixators, controlling the tightness is crucial. If the fixation is too loose, the patient may shift position during surgery, increasing the difficulty and risk of the procedure. If the fixation is too tight, it may increase patient discomfort and even cause skin damage.
[0005] Complex operation: Traditional fixation methods often require multiple adjustments based on the patient's body shape and surgical needs. The operation is cumbersome and time-consuming, increasing the workload of medical staff.
[0006] Therefore, those skilled in the art have proposed a bone marrow puncture position fixing device to solve the problems raised in the background art. Summary of the Invention
[0007] To address the aforementioned technical issues, the present invention provides a bone marrow puncture position fixation device, designed to enhance patient comfort, stability, and personalized adjustment capabilities during the procedure through innovative design. The device utilizes a perforated bedplate with removable rods, allowing for flexible adjustment of the position fixation angle based on the patient's body shape and surgical requirements. Specifically, the rods can be placed at the ankles, knees, and shoulders, allowing precise fixation of the patient's position by fine-tuning the rod's position and angle.
[0008] A bone marrow puncture position fixing device comprises a fixed base, the top of the fixed base is fixedly connected to a connecting bed board, the top of the connecting bed board is fixedly connected to a headboard, and two side walls of the top of the connecting bed board are fixedly connected to two outer baffles;
[0009] The limiting mechanism is arranged at the top end of the connecting bed board.
[0010] Preferably, the limiting mechanism includes mounting holes, which are arranged in groups at the top end of the connecting bed board, the inner side walls of the mounting holes are provided with mounting rods, and the outer side walls of the mounting rods are provided with a plurality of limiting protrusions.
[0011] Preferably, the limiting protrusion on the outside of the mounting rod is snap-connected to the inner wall of the mounting hole, and there are multiple mounting rods, and the top ends of multiple mounting rods are fixedly connected with multiple first limiting rods, among which the outer walls of the top ends of several first limiting rods are fixedly connected with storage sleeves, and the outer walls of the top ends of several other first limiting rods are fixedly connected with second limiting rods, and the outer sides of the first limiting rod, the second limiting rod and the storage sleeve are provided with soft pads that are connected to the patient's skin to prevent the skin from being squeezed.
[0012] Preferably, the inner side wall of the storage sleeve is fixedly connected to a support spring, the outer side wall of the support spring is fixedly connected to a sliding card rod, and the sliding card rod is also slidably connected to the inner side wall of the storage sleeve.
[0013] Preferably, the inner side wall of the second limiting rod is provided with a connecting groove, and the sliding clamping rod limits the second limiting rod through the connecting groove in the second limiting rod.
[0014] Preferably, the mounting rod is engaged with the inner wall of the mounting hole through the outer limiting protrusion, and the limiting protrusion can be arbitrarily installed in different mounting holes.
[0015] Preferably, the length of the first limiting rod is adjusted accordingly according to different torso lengths and sizes, and the storage sleeve and the second limiting rod are adjusted accordingly to the length of the first limiting rod to fix the torso.
[0016] Preferably, the sliding clamping rod and the second limiting rod are snap-connected together to form a whole to limit the torso, and a plurality of spliced mattresses are provided on the top of the connecting bed board. The spliced mattresses are spliced together in multiples and can be freely spliced as needed.
