所属技术领域Technical field
本发明涉及医疗辅助器械技术领域，特别是涉及一种用于脊柱外科手术中的脊柱固定及手术辅助支撑装置。The invention relates to the technical field of medical auxiliary equipment, in particular to a spinal fixation and surgical auxiliary support device used in spinal surgery.
背景技术Background technique
目前国内进行脊柱外科手术主要的是通过人手工进行手术，由于脊柱外科手术是高风险手术，医生长时间进行手术难以保证手工手术操作的持续性精度。利用脊柱手术辅助器械如导引器等可提高手术操作的精度，降低长时间手术因医生疲劳或手颤等因素而对患者造成的伤害几率。At present, domestic spinal surgery is mainly performed manually. Since spinal surgery is a high-risk operation, it is difficult for doctors to perform surgery for a long time to ensure the continuous accuracy of manual surgery. The use of auxiliary equipment for spinal surgery such as guides can improve the accuracy of surgical operations and reduce the chance of injury to patients caused by factors such as doctor fatigue or hand tremors during long-term operations.
随着计算机、微电子技术以及医学科学的迅猛发展，各种计算机辅助医疗技术和设备层出不穷。三维导航引导下的术中导航技术已经开始广泛的使用。医尘根掘计算机辅助设备给出的图像，来确定手术的位置和姿态。With the rapid development of computer, microelectronics technology and medical science, various computer-aided medical technologies and equipment emerge in an endless stream. Intraoperative navigation technology under the guidance of three-dimensional navigation has begun to be widely used. Doctors use the images given by computer-aided equipment to determine the position and posture of the operation.
在利用计算机辅助系统对患者进行脊柱手术时，需要将病患位置处的信息注册到计算机中，一旦注册结束后就要保证病患位置在术中不发生再次移动，因此需要一个固定脊柱的装置，防止在病患脊柱信息注册后发生再一次的移动。同时手术辅助器械需要具有辅助支撑和定位的装置，如机械臂等，本发明和五自由度脊柱手术导引器或六自由度脊柱手术导引器配合使用，为脊柱关节尺寸位置提供了一个外部参考，同时也为脊柱手术导引器的放置提供一个可移动的基座，和其共同组成整个脊柱外科手术辅助系统。当前为脊柱手术导引器定位和支撑的机构只是普通的托架，其结构占用空间大，不利于CT导航系统获取医学影像及计算机信息注册。因此，发明一种用于脊柱手术的脊柱固定及手术辅助支撑装置，能够保证患者脊柱与病床在术中位置的相对固定、支撑脊柱手术导引器并且方便医学影像的扫描及计算机信息注册是本技术领域的一个重要需求。When using a computer-assisted system to perform spinal surgery on a patient, it is necessary to register the information of the patient's position into the computer. Once the registration is completed, it is necessary to ensure that the patient's position does not move again during the operation, so a device for fixing the spine is required , to prevent another movement after the patient's spine information is registered. At the same time, surgical auxiliary instruments need to have auxiliary support and positioning devices, such as mechanical arms. The present invention is used in conjunction with a five-degree-of-freedom spinal surgery guide or a six-freedom spinal surgery guide to provide an external position for the size and position of the spinal joints. Reference, and also provide a movable base for the placement of the spinal surgery guide, together with it to form the entire spinal surgery assisting system. The current positioning and supporting mechanism for the spinal surgery guide is just an ordinary bracket, which takes up a lot of space, which is not conducive to the CT navigation system to obtain medical images and computer information registration. Therefore, inventing a spinal fixation and surgical auxiliary support device for spinal surgery, which can ensure the relative fixation of the patient's spine and the patient's bed during the operation, support the spinal surgery guide, and facilitate the scanning of medical images and computer information registration. An important need in the technical field.
