技术领域technical field
本实用新型涉及推线器，尤其涉及神经内镜颅底手术硬膜缝合推线器。The utility model relates to a thread pusher, in particular to a dural suture thread pusher for 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90％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，亟待解决，鉴于以上缺陷，实有必要设计神经内镜颅底手术硬膜缝合推线器。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 90% 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. Designing the suture site is one of the difficulties in the process of skull base reconstruction in neuroendoscopic skull base surgery, which needs to be solved urgently. In view of the above shortcomings, it is necessary to design a dural suture pusher for neuroendoscopic skull base surgery.

The medical staff then tie the suture at the patient's suture and the other end of the knot passes through the placement hole at the right mounting plate of the fixing rod, and the medical staff then rotates the positioning pin clockwise by hand. Under the action of the screw transmission between the pin and the mounting plate, the positioning pin exerts a pressing force on the suture in the placement hole, so that the suture at both ends of the knot is fixed through the placement hole. At this time, the suture of the suture is fixed. The thread knot is at the bottom of the thread pusher, and the medical staff then places the thumb of the left hand at the position between the placing plate and the connecting belt. The connecting belt has an elastic function. The thumb is firmly connected to the placement plate. The medical staff then inserts the index finger and middle finger of the left hand into the corresponding finger rings on the left and right sides of the sliding sleeve. The medical staff then moves the left thumb and index finger and middle finger toward each other. The sliding sleeve drives the mounting plate to move in the direction of the fixing rod, that is, the mounting plate moves in the direction of the placing plate, synchronously, and the spring is in a compressed state. At this time, the thread pusher pushes the thread knot to move in the direction of the patient's sutured part, and at the same time, the sliding sleeve drives the mounting plate to move along the direction of the placement plate, so that the sutures at both ends of the thread knot are in a horizontal direction, so as to avoid pulling upwards and making it hard The membrane is stretched and torn. Through the above methods, the knot of the suture is pushed to the designated suture site of the patient. The medical staff then rotates the bolt clockwise with the right hand, so that the bolt is inserted into the corresponding positioning hole. The purpose is to push the knot after the suture into a knot to the patient's designated suture site for position fixation. This neuroendoscopic skull base surgery dural suture pusher has an ingenious structure, powerful functions and simple operation. , By using the device, the knot after the suture is knotted can be pushed to the designated suture site of the patient, so that the knot after the suture is knotted and the suture site designated by the patient can be firmly attached to ensure the suture effect. At the same time, the spring is for the sliding sleeve to drive the mounting plate together with the connecting pin and the finger ring to reset quickly. The connecting pin is the mounting carrier of the finger ring and the spring. During the use of the device, when the sliding sleeve moves in the direction of placing the plate , that is, when the sliding sleeve moves in the direction of the fixed rod, the sliding connection between the guide strip and the guide groove prevents the sliding sleeve from rotating along the fixed rod, and ensures that the sliding sleeve moves along the fixed rod. Stability of directional movement.
