Description

An adjustable ventricular drainage tube clamping system for neurosurgery Technical Field

[0001] This invention relates to the field of drainage tube clamping devices, specifically an adjustable ventricular drainage tube clamping system for neurosurgery. Background Technology

[0002] Ventricular drainage is a technique that involves inserting a drainage tube with several side holes into the ventricle through a burr hole or cone hole in the skull. The end of the tube is connected to a sterile drainage bottle to drain cerebrospinal fluid from the body. It is a commonly used treatment and emergency measure in neurosurgery to save lives. Ventricular drainage is suitable for relieving increased intracranial pressure caused by cerebrospinal fluid circulation disorders, especially in cases of impending or newly formed brain herniation. Performing ventricular drainage can prevent or slow the occurrence of brain herniation and has a significant life-saving effect. Drainage tubes are frequently used in ventricular drainage procedures. Commonly used drainage tubes are used in the procedure... In ventricular drainage tube clamping devices are required for positioning and fixation. These tools are called clamping devices. With the rapid development of science and technology, they have also been improved. However, when using existing technology, although the clamping device can be used to position and manage the tube, it is not convenient to adjust the clamping position and direction when the direction of the drainage tube changes or the clamping position is inconvenient. This can easily cause the drainage tube to be bent or compressed at the clamping device, causing inconvenience. In addition, the adjustment and fixation of the device using existing technology is relatively cumbersome, which makes it inconvenient to operate in medical use and affects the effect of use. Summary of the Invention

[0003] The technical problem to be solved by this invention is to overcome the above-mentioned technical defects.

[0004] To solve the above problems, the technical solution of the present invention is: an adjustable ventricular drainage tube clamping system for neurosurgery, comprising a fixation box, an adjustment component, a fixation component, and a clamping component;

[0005] The fixing box has a square structure and is provided with a sliding groove and a recess inside. The recess is located on the front side of the fixing box, and the adjustment component is located inside the sliding groove.

[0006] The adjustment assembly includes a one-way threaded rod, which is rotatably connected to a slide groove and its end passes through the slide groove. A slider is provided on the one-way threaded rod, and a connecting post is connected to the bottom of the slider. An adjustment box is fixedly connected to the bottom of the connecting post, and two clamping cylinders are provided on the adjustment box.

[0007] The fixing component is located in the groove. The fixing component includes a slot located on one side of the groove. The fixing component includes a second spring, which is fixedly connected to the groove. A clamping plate is fixedly connected to its end. Guide rods are fixedly connected to both sides of the clamping plate for limiting the position.

[0008] Furthermore, a rotating wheel is connected to the end of the one-way threaded rod for adjusting rotation.

[0009] Furthermore, the adjustment box is provided with a placement cavity, and a threaded rod is provided in the placement cavity. A second slider is provided on the threaded rod. A connecting groove is fixedly connected to the front side of the second slider. A spring is provided in the connecting groove. A limiting block is fixedly connected to the end of the spring. Connecting rods are fixedly connected to both sides of the limiting block.

[0010] Furthermore, the two connecting rods are respectively fixedly connected to the clamping cylinder for clamping and fixing the clamping cylinder.

[0011] Furthermore, the front side of the clamping plate is provided with a second slot that cooperates with the slot for limiting clamping.

[0012] Furthermore, the clamping assembly includes a clamping cylinder, which comprises a fixed base, a safety locking mechanism, and an anti-dislodgement hook. The adhesive layer on the fixed base uses a medical pressure-sensitive adhesive patch to fix the clamping cylinder to the patient's skin or bed sheet. A strap groove is included. The safety locking mechanism uses a buckle and twist lock to prevent accidental release of the clamping force. The anti-dislodgement hook automatically locks after insertion and requires a specific angle to be pulled out.

[0013] The advantages of this invention compared to existing technologies are:

[0014] The present invention is provided with a fixed box, on which an adjustment component, a fixing component and a clamping component are provided. The one-way threaded rod on the adjustment component is rotatably connected to the slide groove. The movement of the slider on the one-way threaded rod can drive the adjustment box to move, thereby allowing the clamping cylinder to move.

[0015] The fixing component includes a slot located on one side of the groove, which uses the elastic force of spring two to adjust the clamping plate. In addition, guide rods on both sides of the clamping plate are used for limiting the position. Attached Figure Description
