技术领域technical field

本发明涉及神经外科技术领域，具体是一种用于神经外科病人的头部支撑装置。The invention relates to the technical field of neurosurgery, in particular to a head support device for neurosurgery patients.

背景技术Background technique

神经外科(Neurosurgery)是外科学中的一个分支，是在外科学以手术为主要治疗手段的基础上，应用独特的神经外科学研究方法，研究人体神经系统，如脑、脊髓和周围神经系统，以及与之相关的附属机构，如颅骨、头皮、脑血管脑膜等结构的损伤、炎症、肿瘤、畸形和某些遗传代谢障碍或功能紊乱疾病，如：癫痫、帕金森病、神经痛等疾病的病因及发病机制，并探索新的诊断、治疗、预防技术的一门高、精、尖学科，神经外科是主治由于外伤导致的脑部、脊髓等神经系统的疾病，例如脑出血出血量危及生命，车祸致脑部外伤，或脑部有肿瘤压迫需手术治疗等。Neurosurgery is a branch of surgery, which uses unique neurosurgery research methods to study the human nervous system, such as the brain, spinal cord and peripheral nervous system, on the basis of surgery as the main treatment method. Related subsidiary organs, such as skull, scalp, cerebrovascular meninges and other structural injuries, inflammation, tumors, deformities and certain genetic metabolic disorders or dysfunctional diseases, such as: the etiology of epilepsy, Parkinson's disease, neuralgia and other diseases and pathogenesis, and to explore new diagnosis, treatment, and prevention techniques. Neurosurgery is a high-level discipline that treats brain, spinal cord and other nervous system diseases caused by trauma, such as cerebral hemorrhage, which is life-threatening. Brain trauma caused by a car accident, or tumor compression on the brain requiring surgical treatment, etc.

在发生车祸或者头部顶部受到撞击等情况时，需要对大脑的内部结构(如颅骨、头皮等)或者伤口处神经进行检查时，如果病人出现乱动的情况，将会影响检查的进行，经常需要对病人的头部进行支撑并固定处理。When a car accident occurs or the top of the head is hit, etc., it is necessary to check the internal structure of the brain (such as the skull, scalp, etc.) or the nerves at the wound. If the patient moves around, it will affect the inspection. The patient's head needs to be supported and fixed.

在病人检查过程中，往往不方便对病人的头部进行夹持，医护人员在进行调节时，往往不能够对头部进行更加精准的夹持，如果误操作会使病人头部出现疼痛，病人不能根据实际夹持的情况进行微调；对于不同年龄的病人，如成年人与小孩，头部的大小相差较大，常用的夹持装置往往不能有效的适用，使得夹持的效果较差。针对这种情况，本领域技术人员提供了一种用于神经外科病人的头部支撑装置。In the process of patient examination, it is often inconvenient to clamp the patient's head. When the medical staff adjusts, they often cannot clamp the head more accurately. It cannot be fine-tuned according to the actual clamping situation; for patients of different ages, such as adults and children, the size of the head is quite different, and the commonly used clamping device is often not suitable for effective application, making the clamping effect poor. Aiming at this situation, those skilled in the art provide a head support device for neurosurgical patients.

在图1和图3中：插块36的顶部固定安装有推板312，推板312与顶块34的一侧内壁之间设置有弹簧一317，使得插块36可复位。In Fig. 1 and Fig. 3: a push plate 312 is fixedly installed on the top of the insert block 36, and a spring one 317 is arranged between the push plate 312 and one side inner wall of the top block 34, so that the insert block 36 can be reset.

在图1中：底箱1的两侧底部拐角处均固定安装有安装块11，安装块11上设置有安装孔，可对整体进行固定安装，防止在使用过程中发生偏移。In Fig. 1: the bottom corners on both sides of the bottom box 1 are fixedly installed with mounting blocks 11, and the mounting blocks 11 are provided with mounting holes, which can be fixedly installed as a whole to prevent deviation during use.

本发明的工作原理是：病人平躺在病床上，本装置可放置于床头，利用本装置可对头部进行支撑和限位，防止病人乱动，在使用时，病人可将头部放置于枕板2上方，通过医护人员调节第一气缸22，可对头部进行合理高度的支撑，枕板2与连接板32、弧形板31与连接板32、弧形板31与底箱1均转动连接，当枕板2向下运动后，两个夹板320可对头部进行夹持，夹持的位置为太阳穴附近，当夹持的不够紧时，医护人员可推动插块36进行夹持，病人脸颊还可触碰到推杆311，推杆311推动齿条39和插杆38，齿轮310与插块36和齿条39啮接，可推动插块36向脸部靠近，可实现微调使得夹持更紧，左右晃动头部即可实现限位，操作比较简单快捷，插块36向头部运动后，弧形块313的顶部可顺着插块36底部的齿槽滑动，在弹簧二318的作用下，插块36将不会逆向运动，拉动圆块316，可将弧形块313从齿槽内拉出，插块36可实现复位；The working principle of the present invention is: the patient lies flat on the hospital bed, the device can be placed on the head of the bed, and the head can be supported and limited by the device to prevent the patient from moving. When in use, the patient can place the head On the top of the pillow board 2, the first cylinder 22 can be adjusted by the medical staff to support the head at a reasonable height. Both are connected by rotation. When the pillow board 2 moves downward, the two splints 320 can clamp the head. The clamping position is near the temple. When the clamping is not tight enough, the medical staff can push the insert 36 to clamp the head. Hold, the patient's cheeks can also touch the push rod 311, the push rod 311 pushes the rack 39 and the insertion rod 38, the gear 310 meshes with the insertion block 36 and the rack 39, and the insertion block 36 can be pushed closer to the face, which can realize Fine-tuning makes the clamping tighter, and the limit can be realized by shaking the head left and right. Under the action of the second spring 318, the inserting block 36 will not move in reverse, and the circular block 316 can be pulled to pull the arc-shaped block 313 out of the tooth groove, and the inserting block 36 can be reset;

当病人的年龄不同时，脸部的大小也会有差异，可拨动长板33使得滑块46顺着滑槽49滑动，可进一步调节夹板320的位置，启动第二气缸41可将滑动板44从侧槽43内推出，不同位置的凸块45可插入到限位孔47内，可实现对长板33的夹持固定，使得夹板320能更加的适用于不同大小的病人的头部，在使用过程中，启动第三气缸412，可带动连接架413运动，可对弹簧四415进行挤压，可调节挤压板411与滑块46之间的凸起挤压带来的摩擦力，可保持长板33稳定，还可调节长板33滑动的顺畅程度，方便长板33在调节槽48内滑动。When the age of the patient is different, the size of the face will also have differences. The long plate 33 can be moved to make the slider 46 slide along the chute 49, and the position of the splint 320 can be further adjusted, and the second cylinder 41 can be activated to move the slide plate. 44 is pushed out from the side groove 43, and the protrusions 45 at different positions can be inserted into the limiting holes 47, which can realize the clamping and fixing of the long plate 33, so that the splint 320 can be more suitable for the heads of patients of different sizes. During use, starting the third cylinder 412 can drive the connecting frame 413 to move, can squeeze the spring four 415, and can adjust the friction force caused by the convex extrusion between the extrusion plate 411 and the slider 46, The long plate 33 can be kept stable, and the smoothness of the long plate 33 sliding can also be adjusted to facilitate the long plate 33 to slide in the adjustment groove 48 .
