技术领域Technical Field
本发明涉及一种为外科手术骨磨削过程中高温钻头及骨组织提供有效低温冷却的装置，尤其是涉及一种用于钻骨的低温生理盐水刀具内冷装置。The invention relates to a device for providing effective low-temperature cooling for a high-temperature drill bit and bone tissue during surgical bone grinding, and in particular to a low-temperature physiological saline tool internal cooling device for bone drilling.
背景技术Background technique
骨钻削手术经常被应用于整形外科和创伤科等手术治疗中。在骨钻削过程中由于钻削刀具和人体组织的剧烈摩擦,皮质骨的温度会不断上升、力逐渐增大,当温度高于50℃，骨组织会出现不同程度的热损伤，神经组织对温度更为敏感，其热损伤的临界温度值为43℃。目前，在临床医学中最常使用的生理盐水滴灌或外冷却方式对钻骨区域进行冷却，从而冷却高温区域。这种方式冷却效率较低，冷却液不能很好的进入钻削区域，冷却效果不明显。采用低温冷却液可以提高换热性能，但临床中担心采用低温生理盐水进行滴灌冷却会引起流血不止的问题。Bone drilling surgery is often used in surgical treatments such as plastic surgery and traumatology. During the bone drilling process, due to the intense friction between the drilling tool and human tissue, the temperature of the cortical bone will continue to rise and the force will gradually increase. When the temperature is higher than 50°C, the bone tissue will suffer varying degrees of thermal damage. Nerve tissue is more sensitive to temperature, and the critical temperature value of thermal damage is 43°C. At present, the most commonly used method in clinical medicine is to cool the drilled bone area with saline drip irrigation or external cooling, thereby cooling the high-temperature area. This method has low cooling efficiency, the coolant cannot enter the drilling area well, and the cooling effect is not obvious. The use of low-temperature coolant can improve the heat exchange performance, but in clinical practice, there is a concern that the use of low-temperature saline for drip cooling will cause bleeding.
发明内容Summary of the invention
为了克服在外科手术钻骨过程中存在因钻削热量积聚易造成骨组织和神经组织的热损伤、低温生理盐水易引起流血不止的缺陷，本发明提供了一种用于钻骨的低温生理盐水刀具内冷装置，目的就是要尽量降低产生热损伤的风险；采用内冷方式将低温生理盐水形式直接输送至磨削区域持续稳定地降温，通过调节节流阀获得适当的冷却液流量和温度，使磨削区域温度控制在43℃以内，减少手术所带来的二次风险。In order to overcome the defects in the process of bone drilling in surgical operations that the accumulation of drilling heat can easily cause thermal damage to bone tissue and nerve tissue, and low-temperature saline can easily cause bleeding, the present invention provides a low-temperature saline tool internal cooling device for bone drilling, the purpose of which is to minimize the risk of thermal damage; the low-temperature saline is directly delivered to the grinding area in the form of internal cooling to continuously and stably cool it down, and the appropriate coolant flow and temperature are obtained by adjusting the throttle valve, so that the temperature of the grinding area is controlled within 43°C, thereby reducing the secondary risks brought by the operation.
