Description

Technical Field

[0001] The invention relates to the technical field of puncture and drainage of cerebral hemorrhage, in particular to a puncture and drainage fixing device for cerebral hemorrhage. Background Art

[0002] Cerebral hemorrhage puncture and drainage is a commonly used surgical method for treating cerebral hemorrhage in specific cases. Part of the blood is drawn out through puncture, and a drainage tube is placed to drain the remaining blood in small clots. Urokinase and other drugs are injected through the drainage tube to dissolve the blood clots and promote the absorption of hematomas. The existing puncture and drainage devices have certain limitations in the process of puncture and drainage for patients, and are prone to inaccurate puncture positioning during the puncture process, causing secondary injuries to patients and affecting normal puncture and drainage. Inaccurate puncture seriously affects the patient's brain health.

[0003] In order to overcome the above-mentioned defects, prior art 1 (publication number: CN114748302A, Chinese patent with publication date of 2022-07-15) is a cerebral hemorrhage puncture drainage fixation device, which relates to the field of medical equipment technology. Through the cooperation between the set support seat and the fixing component, the two head fixing blocks can be driven to approach each other, thereby achieving the effect of fixing the patient's head, avoiding the patient's head from shaking during the drainage process, thereby affecting the normal head drainage, and after the patient's head drainage is completed, the two threaded rods 2 are rotated so that the two threaded rods 2 drive the two circular extrusion plates away from each other. At this time, with the cooperation between the set spring 1, T-shaped push rod, elastic airbag 1, elastic airbag 1 and connecting tube, the two head fixing blocks can be automatically driven to reset.

[0004] There is also prior art 2 (publication number: CN113520621B, Chinese patent with publication date of 2022-08-09) a cerebral hemorrhage puncture drainage fixation device, which is used for fixing the brain during brain puncture surgery, including a mounting portion and a base, and also includes: a fixing mechanism, the fixing mechanism is arranged on the base, and is used to fix the patient's head; and a buffer mechanism, the buffer mechanism is arranged between the mounting portion and the base, and is used to reduce the impact force generated during the puncture surgery; and a clamping mechanism, the clamping mechanism is arranged on the outer wall of the side of the mounting portion away from the base, and is used to fix the device to the mounting surface. The present invention can flexibly fix the device to different mounting surfaces through the clamping mechanism, and the brain can be restricted by the fixing mechanism on the base, which is convenient for doctors to operate. At the same time, during the puncture and drainage surgery, the buffer mechanism between the mounting portion and the base can effectively mitigate the impact, avoid secondary injuries to the patient, and have a better use effect.

[0005] Although the existing technologies 1 and 2 can limit and fix the patient's head to prevent the patient's head from shaking during the puncture and drainage process, their devices cannot further fix the puncture and drainage equipment, and a single fixation of the patient still has a certain degree of stability.

[0006] Therefore, we propose a puncture drainage fixation device for cerebral hemorrhage to solve the above-mentioned problems. Summary of the invention

At this time, the slide plate is not limited in position. The medical staff can drive the slide plate to slide within the slide slot to limit the position, thereby driving the limit cylinder to move to the part of the patient where puncture is required, thereby improving the applicability of the device. When the puncture is completed, the medical staff can manually rotate the adjustment ring and move the adjustment ring upward. At this time, the adjustment ring will squeeze and push the push plate to move toward the inside of the limit cylinder. During the movement of the push plate, the positioning plate will be driven to move synchronously, so that the positioning plate is close to the drainage tube and clamps the drainage tube to prevent the drainage tube from falling off due to external influences.
