【背景技术】【Background technique】
高血压脑出血(HICH)是病死率极高的疾病，近年来发病人数呈上升趋势，发病年龄也越来越年轻化。不仅病死率高，而且致残率也居所有脑卒中类型的首位。对于幕上大于30ml,幕下大于10ml的脑出血的治疗方法及治疗效果一直是神经外科研究的重要课题。如去大骨瓣减压、大骨窗、小骨窗及近年开展的显微手术、内镜手术虽能在直视下清除颅内血肿，可仍有损伤大、术后并发症多等缺点。另外，高血压脑出血患者以中老年人居多。年老、体弱、甚至患有多种疾病，导致不宜实施全麻、开颅等。目前，国外对高血压脑出血外科治疗多采用“微侵袭”的方法治疗，达到既清除脑内血肿又注重术后的病人生存质量目的，并扩大了手术适应症的范围。目前国外利用先进的立体定向仪，借助超声外科吸引、CUSA、阿基米德钻、旋转绞丝、高压冲洗等方法将血肿粉碎后排出颅外。国内一些先进的大医院已引进上述部分项目，但是上述技术需在手术室全麻下进行，且在术中缺乏对血肿情况的动态监测，更无法床边及急诊救治；更因为设备高精端，治疗费用高。在脑出血的治疗上，国内大部分医院尤其基层医院仍然停留在传统开颅手术和保守治疗上。现有钻颅手术器械包括手动颅骨钻、摇臂式颅骨钻、开颅钻等。随着微创理念的深入，颅骨钻孔微创穿刺术在神经内外科预防、诊断、检测、保护、治疗和研究中已广泛应用。然而，目前没有适合微创钻孔器械。如：颅锥、手摇颅骨钻的使用对外科医生的临床经验和器械操作水平依赖非常强，且手术效果较差，特别是医生无法灵活操作，整个锥颅时间至少10分钟以上甚至更长，长时期操作，患者头部创口出血量大，血液可能回流到颅内，影响医生对病灶的观察和手术正常进行；同时，操作者的劳动强度很大，手术过程产生的疲劳，易造成手术失败；另外，手摇颅骨钻在钻穿颅骨的瞬间，无法自动停机，仅由操作者凭经验及手感判断停机，出错的风险极高，钻头10经常损伤硬脑膜，甚至深人到脑功能中枢区.造成死亡率很高的严重性手术事故。而急性脑积水、脑室内出血呼吸骤停的患者，呼吸停止超过6分钟脑组织就会产生不可逆的病理变化。所以对于急性脑积水、脑室内出血呼吸骤停的患者，急需一种钻颅时间在6分钟以内的锥颅工具。气动手术动力装置的机械结构尺寸较小，重量比较轻，钻头10受氢气或氮气等高压惰性气体驱动高速旋转，切削效果好。但是，需要专门的惰性气体源和复杂的耐高压辅助管路系统，而这些辅助设备和条件只有规模很大的医院拥有，而且气动钻的停机是靠操作者的力感手动控制，这种安全性隐患限制了气动钻使用范围。电机式手术动力系统采用大功率电机和微型电机作驱动动力源，软轴传递大动力扭矩，微电机提供高速转动，使用先进嵌人式计算机控制技术实现外科手术钻、铣、磨、锯摆全部功能，但其体积相对较大，需有线电源、价格较昂贵，对微创钻孔术来说其使用并不具有优势，连有软轴，其操作使用明显受到影响。Hypertensive intracerebral hemorrhage (HICH) is a disease with a high mortality rate. In recent years, the number of patients has been on the rise, and the age of onset is getting younger and younger. Not only the fatality rate is high, but also the disability rate ranks first among all stroke types. The treatment method and effect of cerebral hemorrhage greater than 30ml above the tentorium and greater than 10ml below the tentorium have always been an important subject of neurosurgery research. For example, decompressive large bone craniectomy, large bone window, small bone window, and microsurgery and endoscopic surgery developed in recent years can remove intracranial hematoma under direct vision, but there are still disadvantages such as large damage and many postoperative complications. In addition, most patients with hypertensive cerebral hemorrhage are middle-aged and elderly people. Old age, infirmity, or even suffering from various diseases make general anesthesia and craniotomy unsuitable. At present, the surgical treatment of hypertensive intracerebral hemorrhage in foreign countries mostly adopts the "micro-invasive" method to achieve the goal of removing intracerebral hematoma and paying attention to the quality of life of patients after surgery, and expands the scope of surgical indications. At present, advanced stereotaxic instruments are used abroad, and methods such as ultrasonic surgical suction, CUSA, Archimedes drill, rotating twisted wire, and high-pressure washing are used to crush the hematoma and discharge it outside the skull. Some advanced large hospitals in China have introduced some of the above-mentioned projects, but the above-mentioned technologies need to be carried out under general anesthesia in the operating room, and there is no dynamic monitoring of the hematoma during the operation, let alone bedside and emergency treatment; moreover, because of the high-end equipment , high treatment costs. In the treatment of cerebral hemorrhage, most hospitals in China, especially grassroots hospitals, still stay on traditional craniotomy and conservative treatment. Existing cranial drilling instruments include manual skull drills, rocker arm type skull drills, craniotomy drills and the like. With the deepening of the concept of minimally invasive, minimally invasive puncture of skull drilling has been widely used in the prevention, diagnosis, detection, protection, treatment and research of neurology and surgery. However, there are currently no suitable minimally invasive drilling instruments. For example, the use of cranial cones and hand-operated skull drills is very dependent on the surgeon's clinical experience and equipment operation level, and the surgical effect is poor, especially if the doctor cannot operate flexibly. During long-term operation, the patient's head wound will bleed a lot, and the blood may flow back into the brain, which will affect the doctor's observation of the lesion and the normal operation. At the same time, the operator's labor intensity is very high, and the fatigue generated during the operation may easily lead to operation failure. ;In addition, the hand-operated skull drill cannot stop automatically at the moment of drilling through the skull, and the operator can only judge the shutdown based on experience and hand feeling, and the risk of making mistakes is extremely high. . Serious surgical accidents with a high mortality rate. In patients with acute hydrocephalus and intraventricular hemorrhage and respiratory arrest, irreversible pathological changes will occur in the brain tissue if the breathing stops for more than 6 minutes. Therefore, for patients with acute hydrocephalus and intraventricular hemorrhage and respiratory arrest, there is an urgent need for a cranial cone tool with a drilling time of less than 6 minutes. The mechanical structure of the pneumatic surgery power unit is small in size and light in weight. The drill bit 10 is driven by high-pressure inert gas such as hydrogen or nitrogen to rotate at high speed, and the cutting effect is good. However, a special inert gas source and a complex high-pressure-resistant auxiliary pipeline system are required, and these auxiliary equipment and conditions are only available in large-scale hospitals, and the shutdown of the pneumatic drill is manually controlled by the operator's sense of force. Sexual hazards limit the scope of use of pneumatic drills. The motor-type surgical power system uses high-power motors and micro-motors as the driving power source, the flexible shaft transmits large power torque, and the micro-motor provides high-speed rotation. It uses advanced embedded computer control technology to realize surgical drilling, milling, grinding and sawing. Function, but its volume is relatively large, it needs a wired power supply, and its price is relatively expensive. It does not have advantages in its use for minimally invasive drilling. It is connected with a flexible shaft, and its operation and use are obviously affected.
此外，现有的钻孔装置都没有对钻孔的骨渣处理，都是钻的过程中用生理盐水冲洗或钻完后掏洗，常出现掏洗不净及淘洗过程中对周围组织再损伤，引起出血较多、伤口不易愈合。另外，目前医院所用钻头10较大，以直径8――12mm居多，而微创钻孔术所需一般为直径6mm及以下。钻头10大，所需切口明显扩大，出血明显增多，对引流管固定，止血都会影响，由于钻孔较大，引流管进入颅内方向，位置容易改变，易出现穿刺位置偏差或穿刺失败。In addition, the existing drilling devices do not deal with the drilled bone residues. They are all rinsed with normal saline during the drilling process or washed after drilling. It often occurs that the washing is not clean and the surrounding tissues are regenerated during the elutriation process. Injury, causing more bleeding and difficult wound healing. In addition, the drill bits 10 used in hospitals are relatively large at present, mostly with a diameter of 8-12mm, while the required diameter of minimally invasive drilling is generally 6mm and below. The size of the drill bit is 10, the required incision is significantly enlarged, and the bleeding is significantly increased, which will affect the drainage tube fixation and hemostasis. Due to the large drill hole, the drainage tube enters the intracranial direction, and the position is easy to change, which is prone to puncture position deviation or puncture failure.

【具体实施方式】【detailed description】
下列实施例是对本发明的进一步解释和补充，对本发明不构成任何限制。The following examples are further explanations and supplements to the present invention, and do not constitute any limitation to the present invention.
如图1～图3所示，本发明的多功能颅钻包括主机1和钻头10两部分。所述主机1包括电池3卡槽2、电池3、手柄4、马达、照明灯5、开关保险6、散热孔7、电机、钻头10连接卡槽底座8及离合装置。所述电池3卡槽2设于主机1的底端，所述电池3装设于所述电池3卡槽2内，所述照明灯5装设于所述手柄4的前端，所述开关保险6装设于手柄4易于操控的位置，所述电机设于所述主机1内，所述散热孔7与所述电机位置相对应。所述钻头10连接卡槽底座8可选用公知的结构，其设于主机1的头端，用于可拆卸连接钻头10。所述钻头10可拆卸地与所述钻头10连接卡槽底座8连接。为实现自停，在所述钻头10上设有传感器9，该传感器9与电机联动连接。当传感器9检测到钻头10钻透时，传感器9便联动所述电机断电而停止工作。本实施例中，所述传感器9包括转速传感器929和转矩传感器919。所述转速传感器929用于实时检测钻头10的转速。所述转矩传感器919用于实时检测钻头10的转矩。由于钻头10钻透骨头时，其钻速会突然升高，因此可通过转矩传感器919检测钻头10是否钻透骨头。此外，为防止误判，利用转矩传感器919进一步检测来判断钻头10是否真正钻头10。这样，当钻头10一旦钻透骨头，传感器9检测到相应的信号，便联动所述电机停止工作，从而迫使所述钻头10及时停止转动，有效避免假通情况的发生，避免电机空转而损坏电机。As shown in FIGS. 1 to 3 , the multifunctional cranial drill of the present invention includes two parts: a host machine 1 and a drill bit 10 . The host 1 includes a battery 3 slot 2, a battery 3, a handle 4, a motor, a lamp 5, a switch insurance 6, a cooling hole 7, a motor, a drill 10 connected to a slot base 8 and a clutch device. The battery 3 slot 2 is arranged at the bottom of the host 1, the battery 3 is installed in the battery 3 slot 2, the lighting lamp 5 is installed at the front end of the handle 4, and the switch is secured. 6 is installed at a position where the handle 4 is easy to operate, the motor is arranged in the host 1, and the cooling hole 7 corresponds to the position of the motor. The drill bit 10 can be connected to the slot base 8 using a known structure, which is arranged at the head end of the host 1 for detachable connection to the drill bit 10 . The drill bit 10 is detachably connected to the drill bit 10 connection slot base 8 . In order to realize self-stop, a sensor 9 is arranged on the drill bit 10, and the sensor 9 is linked with the motor. When the sensor 9 detects that the drill bit 10 has penetrated, the sensor 9 will be linked to the power failure of the motor to stop working. In this embodiment, the sensor 9 includes a rotational speed sensor 929 and a torque sensor 919 . The rotational speed sensor 929 is used to detect the rotational speed of the drill bit 10 in real time. The torque sensor 919 is used to detect the torque of the drill bit 10 in real time. Because the drill bit 10 drills through the bone, its drilling speed will suddenly increase, so the torque sensor 919 can be used to detect whether the drill bit 10 drills through the bone. In addition, in order to prevent misjudgment, the torque sensor 919 is used for further detection to determine whether the drill bit 10 is a real drill bit 10 . In this way, once the drill bit 10 drills through the bone, the sensor 9 detects a corresponding signal, and the motor is linked to stop working, thereby forcing the drill bit 10 to stop rotating in time, effectively avoiding the occurrence of a false connection, and avoiding the motor from idling and damaging the motor .
本实施例中，所述钻头10可拆卸，其可根据需要而选择不同类型的钻头10，其优选不锈钢钻头10。In this embodiment, the drill bit 10 is detachable, and different types of drill bits 10 can be selected according to needs, and stainless steel drill bits 10 are preferred.
如图2所示，为方便钻孔，在所述钻头10上套设有可调套管11。所述可调套管11呈圆管状，其内径与所述钻头10的外径相匹配。所述可调套管11的尖端为锯齿状，当可调套管11套设于钻头10外时，其锯齿端与钻头10的端部靠近，可调套管11的锯齿端可进一步增加钻孔时切割骨质的速度，从而起到省力的作用。在所述可调套管11的中部设有外螺纹12，其用于螺纹连接三角架13。所述三角架13可选用公知的三角架13，其通过螺母可与所述可调套管11螺纹连接。钻孔时，在所述可调套管11外螺纹12连接三角架13可起到固定钻头10的作用，防止钻头10在钻孔过程中晃动。为使可调套管11与钻头10相对固定进行使用，在所述可调套管11的与锯齿端相对的一端端部设有钻头固定螺钉14。所述钻头固定螺钉14与所述可调套管11垂直，其可拧紧拧松而调节可调套管11在钻头10上的位置。此外，在所述可调套管11上还设有若干个通孔15，其用于排渣。As shown in FIG. 2 , in order to facilitate drilling, an adjustable sleeve 11 is sheathed on the drill bit 10 . The adjustable sleeve 11 is in the shape of a circular tube, and its inner diameter matches the outer diameter of the drill bit 10 . The tip of the adjustable sleeve 11 is serrated. When the adjustable sleeve 11 is sleeved outside the drill bit 10, its serrated end is close to the end of the drill bit 10. The serrated end of the adjustable sleeve 11 can further increase the drill bit. The cutting speed of the bone when the hole is cut, so as to save labor. The middle part of the adjustable sleeve 11 is provided with an external thread 12, which is used for threading the tripod 13. The tripod 13 can be a known tripod 13, which can be threadedly connected with the adjustable sleeve 11 through a nut. When drilling, connecting the tripod 13 with the external thread 12 of the adjustable sleeve 11 can play a role in fixing the drill bit 10, preventing the drill bit 10 from shaking during the drilling process. In order to make the adjustable sleeve 11 and the drill bit 10 relatively fixed for use, a drill fixing screw 14 is provided at one end of the adjustable sleeve 11 opposite to the sawtooth end. The drill bit fixing screw 14 is perpendicular to the adjustable sleeve 11 , which can be tightened and loosened to adjust the position of the adjustable sleeve 11 on the drill bit 10 . In addition, several through holes 15 are provided on the adjustable sleeve 11 for slag discharge.
藉此，便形成了本实用新型的多功能颅钻。使用前，先根据需要而调节可调套管11在钻头10上的位置，并装好三角架13。当手术环境光线较暗时，可通过多功能颅钻手柄4前端的照明灯5进行照明。钻孔时，由于三脚架的作用，钻头10不易移动而造成钻孔偏位及滑动。且由于钻头10外设有可调套管11，可调套管11上设有通孔15，钻孔时刻有效将骨渣导出头皮外，防止骨渣进入脑皮质内，引起继发性癫痫。此外，由于钻头10外套设有可调套管11，其能有效固定于颅骨上，防止钻孔后皮肤软组织移位，遮挡钻孔处，以致为反复寻找钻孔处，引起局部过多出血，及皮肤组织损伤，甚至置管失败。由于本发明依靠离合装置实现自停，其钻头10较小，可实现微创，且使用过程中不会出现钻头10晃动等情况，不会受患者骨质影响而出现假通情况。此外，本实用新型颅钻的主机1可以与钻头10分离，在急诊、急用或多个患者使用时，只需高温消毒钻头10、或更换钻头10，主机1使用隔离袋便可以使用，其方便而实用。本实用新型的多功能颅钻具有快速、方便、安全、微创、定位、定向、排屑、导引、及利于冲洗等作用，宜大力实施。Thereby, the multifunctional cranial drill of the present utility model is formed. Before use, adjust the position of the adjustable sleeve 11 on the drill bit 10 as required, and install the tripod 13 . When the operating environment is dark, it can be illuminated by the illuminating lamp 5 at the front end of the multifunctional cranial drill handle 4 . During drilling, due to the effect of the tripod, the drill bit 10 is not easy to move and cause drilling deviation and sliding. And because the drill bit 10 is provided with an adjustable sleeve 11, the adjustable sleeve 11 is provided with a through hole 15, and the bone dregs are effectively exported outside the scalp during drilling to prevent the bone dregs from entering the cerebral cortex and causing secondary epilepsy. In addition, since the drill bit 10 is covered with an adjustable sleeve 11, it can be effectively fixed on the skull to prevent the skin and soft tissue from shifting after drilling, and to block the drilling site, so that excessive local bleeding may be caused in order to repeatedly search for the drilling site. And skin tissue damage, or even catheter failure. Because the present invention relies on the clutch device to realize self-stopping, the drill bit 10 is small, which can realize minimally invasive, and the drill bit 10 will not shake during use, and will not be affected by the patient's bone quality to cause false passage. In addition, the main unit 1 of the cranial drill of the present invention can be separated from the drill bit 10. When emergency treatment, emergency use or multiple patients are used, only the high-temperature disinfection of the drill bit 10 or the replacement of the drill bit 10 is required, and the main unit 1 can be used with an isolation bag, which is convenient. And practical. The multifunctional cranial drill of the utility model has functions such as quickness, convenience, safety, minimally invasiveness, positioning, orientation, chip removal, guidance, and benefit for washing, and should be implemented vigorously.
