Neuroendoscopy skull base surgery dural suture pusher

Abstract

The invention discloses a neuroendoscopy skull base surgery dural suture pusher, including a fixing rod, a push head, a sliding sleeve, a mounting plate, a placing hole, a link pin, a finger ring, a placing plate, and a spring. The neuroendoscopy skull base surgery dural suture pusher has the advantages of ingenious structure, powerful function, and simple operation. By using the device, the suture knot can be pushed to a designated suture position of a patient, so that the suture knot after the knot is formed can be stably adhered to the designated suture position of the patient, and the suture effect is ensured.

Description

technical field [0001] The invention relates to a thread pusher, in particular to a thread pusher for endoscopic skull base surgery. Background technique [0002] At present, with the development of neuroendoscopic surgery techniques, more and more ventral skull base lesions and deep brain lesions that previously required craniotomy under a microscope can be resected by neuroendoscopic surgery. For example, approximately 90% of pituitary adenoma surgeries can be performed through endoscopic nasal surgery. The concept of total endoscopic skull base surgery has been accepted by more and more neurosurgeons. Compared with craniotomy microsurgery, neuroendoscopic surgery has many advantages such as close observation of lesions, less disturbance to brain tissue through the nose, wide-angle view, no facial incision, faster postoperative recovery, and shorter hospital stay. However, this method also has its own limitations. After endoscopic surgery, the operation area is deep, it...

AI Technical Summary

Problems solved by technology

After endoscopic surgery, the operation area is deep, and it is difficult to suture the dura mater. 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 operation cavity is deep, there is less room for other surgical instruments to operate, and the freedom of movement of the instruments is limited so it is difficult to complete the deep knotting operation, especially how to push the knot to the Specifying the suture site is one of the difficulties in the skull base reconstruction process in neuroendoscopic skull base surgery, which needs to be solved urgently. In view of the above defects, it is necessary to design a dural suture pusher for neuroendoscopic skull base surgery
