A dural suture pusher for simulating neuroendoscopic skull base surgery

Abstract

The invention discloses a neuroendoscopy skull base surgery dura mater suture line pusher for simulation. The neuroendoscopy skull base surgery dura mater suture line pusher for simulation comprises acasing, wherein the upper end of the casing is provided with a fixing block; a first movable post is arranged at the upper end of the casing in a penetrating and inserting way; a second movable postis arranged at the lower end of the casing in a penetrating and inserting way; the upper end of the first movable post is provided with a position limiting block; the lower end of the second movable post is provided with a line pushing block; the second movable post and the casing are connected through a movable sleeve; the lower end of each of the two sides of the casing is provided with a fixingdevice; hooks are arranged above the fixing devices and at the two sides of the casing; an opening is formed above the hooks and is positioned at one side of the casing; the fixing device comprises afirst fixing plate and a second fixing plate; one side of the first fixing plate is connected with the casing; an accommodating groove is formed between the first fixing plate and the second fixing plate; a first movable plate is arranged at each of two sides of one end of the first fixing plate; a second movable plate is arranged at each of two sides of the other end of the first fixing plate; in addition, the ends, far away from the first fixing plate, of the first movable plates and the second movable plates are connected with a movable rod; and the first movable plates and the second fixing plate are connected through a first movable shaft.

Description

technical field [0001] The invention relates to the medical field, in particular to a thread pusher for simulating neuroendoscopic skull base surgery for dura mater suture. 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 95% 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...

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.
