一种用于模拟神经内镜颅底手术硬膜缝合推线器A dural suture pusher for simulating neuroendoscopic skull base surgery

技术领域technical field

本发明涉及医疗领域，具体来说，涉及一种用于模拟神经内镜颅底手术硬膜缝合推线器。The invention relates to the medical field, in particular to a dural suture thread pusher for simulating neuroendoscopic skull base surgery.

背景技术Background technique

目前，随着神经内镜手术技术的发展，越来越多的先前需要开颅在显微镜下完成的腹侧颅底病变和脑深部病变能够通过神经内镜手术切除。比如，约95％的垂体腺瘤手术能通过经鼻内镜手术完成。全内镜下颅底外科的概念被越来越多的神经外科医生接受。神经内镜手术与开颅显微手术相比具有近距离观察病变、经鼻完成对脑组织骚扰轻、广角视野、无颜面部切口、术后康复快、住院时间短等诸多优点。但该术式亦有其自身的局限性。内镜手术后术区深在，缝合硬脑膜困难，围手术期容易发生脑脊液漏和颅内感染，在某种程度上影响了神经内镜颅底手术的推广。由于内镜本身占据一定空间，术腔较深，留给其他手术器械的操作空间较小，器械移动自由度受限难以完成深部打结操作，特别是缝线成结后如何将线结推向指定缝合部位是神经内镜颅底手术中颅底重建过程的难点之一，因此，增加手术医生的模拟操作训练提高手术技巧是解决这一难题的最佳方案。At present, with the development of neuroendoscopic surgical techniques, more and more lesions of the ventral skull base and deep brain lesions that previously required craniotomy to be completed under the microscope can be resected by neuroendoscopic surgery. For example, about 95% of pituitary adenoma surgery can be done by transnasal endoscopic surgery. The concept of total endoscopic skull base surgery is increasingly accepted by neurosurgeons. Compared with craniotomy microsurgery, neuroendoscopic surgery has many advantages, such as close observation of lesions, less harassment of brain tissue, wide-angle field of view, no facial incision, faster postoperative recovery, and shorter hospital stay. But this technique also has its own limitations. After endoscopic surgery, the operative area is deep, it is difficult to suture the dura mater, and cerebrospinal fluid leakage and intracranial infection are prone to occur during the perioperative period, which affects the promotion of neuroendoscopic skull base surgery to some extent. Since the endoscope itself occupies a certain space and the surgical cavity is deep, there is less room for other surgical instruments to operate, and the freedom of movement of the instruments is limited, and it is difficult to complete the deep knotting operation, especially how to push the knot to the suture after the knot is formed. Specifying the suture site is one of the difficulties in the process of skull base reconstruction in neuroendoscopic skull base surgery. Therefore, increasing the surgeon's simulated operation training to improve surgical skills is the best solution to this problem.

为了方便理解本发明的上述技术方案，以下就本发明在实际过程中的工作原理或者操作方式进行详细说明In order to facilitate the understanding of the above technical solutions of the present invention, the working principle or operation mode of the present invention in the actual process will be described in detail below.

在实际应用时：首先受训医生将缝合部位的缝合线打结后线结的一端穿过壳体1左侧的放置槽13内，再将另一端穿过壳体1 右侧的放置槽13，此时，受训医生拉动拉绳19，将拉绳19挂到挂钩9上，进而拉绳19固定，因此，拉绳19带动连接块18运动，使得连接块18带动活动杆16运动，因为活动杆16与活动板一14及活动板二15通过活动轴三22连接，进而活动杆16的运动带动活动板一14及活动板二15运动，因为活动板一14与固定板二12之间通过活动轴一17连接，进而活动板一14带动固定板二12向上运动，进而放置槽13内的两侧锯齿20相互接触，将线结固定在放置槽13的内侧，此时，缝合线的线结处于推线块6的底部位置，通过夹槽35将线接卡住，受训医生再用大拇指按压挤压片23，使得挤压片23向壳体1内侧运动，当挤压片 23上的连接柱30与开口10分离时，连接柱30完全进入到壳体 1的内侧，此时，弹簧28处于展开状态，通过弹簧28产生弹力，使得活动柱一3带动弹簧28向活动柱二4的方向运动，进而弹簧 28带动挡块27挤压挡片二31，使得挡片二31挤压连接柱30及挡片一29，因为挡片一29与限位柱24通过卡槽32连接，进而挡片一29挤压活动柱二4使得活动柱二4向壳体1的外侧运动，此时，推线块6推动线结沿着缝合部位方向移动，通过导向条33 和导向槽34滑动相连的作用，防止活动柱一3沿着活动套7方向移动时不会出现旋转现象的发生，确保了活动柱一3移动的稳定性。In practical application: firstly, the trained doctor ties the suture at the suture, and then one end of the knot passes through theplacement slot 13 on the left side of thehousing 1, and then passes the other end through theplacement slot 13 on the right side of thehousing 1, At this time, the trainee pulls thepull rope 19, hangs thepull rope 19 on thehook 9, and then fixes thepull rope 19. Therefore, thepull rope 19 drives the connectingblock 18 to move, so that the connectingblock 18 drives themovable rod 16 to move, because themovable rod 16 is connected with themovable plate 1 14 and themovable plate 2 15 through themovable shaft 3 22, and then the movement of themovable rod 16 drives themovable plate 1 14 and themovable plate 2 15 to move, because themovable plate 14 and the fixedplate 2 12 pass through the movement. The shaft one 17 is connected, and the movable plate one 14 drives the fixed plate two 12 to move upward, and then the two sides of theserrations 20 in theplacement groove 13 contact each other, and the knot is fixed on the inner side of theplacement groove 13. At this time, the knot of the suture thread At the bottom position of thepush wire block 6, the wire connection is clamped by theclip groove 35, and the trainee presses thesqueeze sheet 23 with his thumb, so that thesqueeze sheet 23 moves to the inside of thehousing 1. When the connectingcolumn 30 is separated from theopening 10, the connectingcolumn 30 completely enters the inner side of thehousing 1. At this time, thespring 28 is in an expanded state, and thespring 28 generates elastic force, so that themovable column 13 drives thespring 28 to themovable column 24. Then thespring 28 drives thestopper 27 to squeeze thesecond stopper 31, so that thesecond stopper 31 squeezes the connectingpost 30 and thestopper piece 1 29, because thestopper piece 29 and thelimit post 24 are connected through theslot 32, and then The blockingpiece 29 squeezes themovable column 2 4 to move themovable column 2 4 to the outside of thehousing 1 . At this time, thethread pusher block 6 pushes the thread knot to move along the direction of the suture, and is slidably connected to theguide groove 34 through theguide bar 33 It can prevent the rotation phenomenon from occurring when the movable column one 3 moves along the direction of themovable sleeve 7, and ensure the stability of the movement of the movable column one 3.

综上所述，借助于本发明的上述技术方案，通过壳体1内的伸缩装置带动推线块6运动，使得推线块6将缝线成结后的线结推向患者的指定缝合部位，通过弹簧28的弹力作用，受训医生将缝线成结后的线结推向的指定缝合部位的状态进行位置固定；本发明的模拟神经内镜颅底手术硬膜缝合推线器，结构简单，功能强大，操作方便，使用该装置确保了缝合效果，通过导向条33和导向槽34滑动相连的作用，防止活动柱一3沿着活动套7方向移动时不会出现旋转现象的发生，确保了活动柱一3移动的稳定性。To sum up, with the help of the above technical solutions of the present invention, thepusher block 6 is driven to move by the telescopic device in thehousing 1, so that thepusher block 6 pushes the knotted suture to the designated suture site of the patient. , through the elastic force of thespring 28, the trainee will fix the position of the designated suture position where the suture is pushed into the knot; the dural suture pusher for simulating neuroendoscopic skull base surgery of the present invention has a simple structure , powerful function, easy to operate, the use of this device ensures the stitching effect, through the sliding connection of theguide strip 33 and theguide groove 34, to prevent themovable column 1 3 from moving along themovable sleeve 7. The phenomenon of rotation will not occur, ensuring that The stability of the movement of the movable column one 3 is improved.
