Description

Technical Field

[0001] The present invention belongs to the technical field of medical auxiliary devices. Specifically, it particularly relates to a brain surgery auxiliary device. Background Art

[0002] Neurosurgery is a branch of surgery. Based on surgery as the main treatment method, it applies unique neurosurgical research methods to study the human nervous system, such as the brain, spinal cord, and peripheral nervous system, as well as related accessory organs, such as structures like the skull, scalp, cerebral blood vessels, and meninges. It also studies injuries, inflammations, tumors, deformities, and certain genetic metabolic disorders or functional disorders of these structures. A brain surgery auxiliary device refers to various devices and instruments used in neurosurgery to assist doctors in surgical operations, ensuring surgical precision and patient safety. These devices are usually designed to fix the patient's head, provide a clear surgical field of view, assist in positioning, and simplify surgical procedures, etc.

[0003] After retrieval, Chinese Patent No. CN115462997A discloses a neurosurgical brain surgery auxiliary instrument, which relates to the field of neurosurgery. The first ends of two first connecting rods are respectively connected to the outer sides of two support legs. The second ends of the two first connecting rods are respectively movably connected to support seats, and the second ends of the two first connecting rods are respectively connected to both ends of the support seats. In the present invention, by pulling the handle outwards, when the handle drives the support seat to move outwards, it also drives the second connecting rod to move upwards. When it moves to a suitable position, the patient lies on the bed board, places the head on the head support block, and then adjusts the clamping device to clamp and fix the patient's head, which is convenient for doctors to perform brain surgery. Compared with the existing surgical headrests, the operation is simple, and the inconvenience of adjusting and fixing each rotating joint is eliminated. At the same time, when the present invention is not in use, the self-locking nut can be directly loosened, and under the action of the spring, the entire brain surgery auxiliary instrument automatically moves under the bed board, without occupying space. However, when the above patent is actually used, the angle of the patient's head cannot be adjusted, which is not conducive to subsequent surgical operations. And when the above patent is actually used, it cannot fix and clamp patients with different head sizes, resulting in the need to replace different clamping plates, reducing the surgical efficiency. Summary of the Invention

[0004] In view of the problems in the related art, the present invention proposes a brain surgery auxiliary device to overcome the above-mentioned technical problems existing in the related art.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention relates to a brain surgery assistance device, including an operating table. The operating table is rotatably installed with a bed board. One end of a connecting rod is rotatably installed on the bed board, and the other end of the connecting rod is rotatably installed on a sliding block. The sliding block is slidably connected inside a first chute. The first chute is opened on the operating table. A first threaded rod is rotatably installed inside the first chute, and the first threaded rod is threadedly connected with the sliding block; By rotating the first threaded rod, the sliding block moves along the inside of the first chute, driving the connecting rod to rotate, and causing the bed board to rotate along the operating table; A buffer headrest is arranged above the bed board. A second chute is opened above the bed board, and a fixing mechanism is arranged inside the second chute. The fixing mechanism is used to fix the patient's head.

[0006] Further, one end of the first threaded rod is fixedly installed with a first handle, and the first handle is rotatably installed on the operating table.

[0007] Further, the fixing mechanism includes a bidirectional threaded rod arranged inside the second chute. The bidirectional threaded rod is rotatably installed inside the second chute, and the bidirectional threaded rod is threadedly connected with a first rod.

[0008] Further, a second rod is slidably connected inside the first rod. The second rod is fixedly installed with an arc-shaped fixing plate, and a protective pad is fixedly installed inside the arc-shaped fixing plate.

[0009] Further, a second threaded rod is rotatably installed inside the first rod. The second threaded rod is threadedly connected with the second rod. The second threaded rod is fixedly installed with a turbine, and the turbine meshes with a worm. The worm is rotatably installed on the first rod.

[0010] Further, one end of the bidirectional threaded rod is fixedly installed with a first bevel gear. The first bevel gear is rotatably installed inside the bed board, and the first bevel gear meshes with a second bevel gear.

[0011] Further, the second bevel gear is rotatably installed inside the bed board. The second bevel gear is fixedly installed with a second handle, and the second handle is rotatably installed on the bed board.

[0012] Further, a connecting block is fixedly installed on one side of the operating table. The connecting block is provided with a connecting hole, and an elastic band is fixedly installed on the other side of the operating table.

[0013] Further, a magic tape is arranged on the elastic band. The magic tape passes through the connecting hole to form a fixation.

[0014] Further, support legs are fixedly installed at the bottom of the operating table, and there are four support legs.

[0015] The present invention has the following beneficial effects compared with the prior art: 1. Through the cooperation of the first threaded rod and the sliding block, the present invention can flexibly adjust the angle of the bed board, thereby changing the position of the patient's head. This design enables medical staff to easily adjust the head angle of the patient as needed during the operation, providing great convenience for the operation, and improving the accuracy and safety of the operation.

[0016] 2. Through the combination of the bidirectional threaded rod, the first rod, the second rod, the arc-shaped fixing plate and the protective pad, the present invention realizes the personalized clamping and fixing of the patient's head. Medical staff can adjust the position of the second rod in the first rod according to the size of the patient's head to ensure that the head is firmly fixed. This design not only improves the comfort of the patient, but also enhances the stability during the operation and reduces the surgical risks caused by head shaking.

[0017] 3. The present invention firmly clamps the patient's head through the fixing mechanism. On the other hand, elastic bands and Velcro are used to tie and tighten the patient's body parts to prevent the patient from shaking during the operation. Under the combined action of these measures, it provides all-round safety protection for the operation process, further improving the safety and success rate of the operation.

[0018] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS
