Abstract
The utility model discloses a subdural drainage tube which comprises a drainage tube body, a soft metal needle core and an air bag. An air inlet channel is formed in the tube wall of the drainage tube body, the soft metal needle core is arranged in the air inlet channel of the drainage tube body, a side air hole is formed in the head end of the drainage tube body, and the air bag is arranged on the side air hole. The subdural drainage tube is convenient to use, can be shaped at will in an operation, and can reduce the injury probability of the brain tissues substantially. The subdural drainage tube can be fixed after being placed in and effectively reduce the occurrence rate of postoperation subdural or epidural hematoma, the drainage tube body can be effectively prevented from slipping off, the air bag is convenient to inflate and deflate, and the drainage tube is not pulled out stiffly.
Description
Technical field
This utility model relates to a kind of medical instrument, in particular drainage tube under a kind of dura mater.
Background technology
Subdural effusion and chronic subdural hematoma are the neurosurgery commonly encountered diseases, and under traditional silica gel dura mater, the drainage tube quality is soft, and the sphenotresia aperture is less, drainage tube is inserted inconvenience, the easy damaged cerebral tissue, sometimes even need to enlarge boring, and this often may cause under the secondary dura mater or epidural hematoma.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and drainage tube under a kind of dura mater is provided, can be according to different operative site random-shapings in art, and the inner table of skull so that drainage tube is fitted to greatest extent, effectively fixedly drainage tube is avoided slippage.
This utility model is achieved through the following technical solutions, this utility model comprises drainage tube, soft metal nook closing member and air bag, in the tube wall of described drainage tube, is provided with air intake duct, and the soft metal nook closing member is arranged in the air intake duct of drainage tube, the head end of drainage tube is provided with the side pore, and air bag is arranged on the side pore.
The end of described drainage tube is provided with irrigation channel, and described irrigation channel and drainage tube form y-type structure.Irrigation channel is for rinsing.
Described drainage tube length is 20～30cm, can meet general neurosurgery demand.
The head end of described soft metal nook closing member is provided with conical blunt nosed, and end is provided with draw ring, can be according to different operative site random-shapings in art, and the inner table of skull so that drainage tube is fitted to greatest extent, avoid injured brain tissue.
This utility model has the following advantages compared to existing technology: this utility model is easy to use, but random-shaping in art can significantly reduce the brain tissue impairment probability; Can fix after inserting, effectively prevent the drainage tube slippage; Can effectively reduce under postoperative dura mater or the epidural hematoma incidence rate; The air bag inflation/deflation is convenient, not rigid tube drawing.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below embodiment of the present utility model is elaborated; the present embodiment is implemented take technical solutions of the utility model under prerequisite; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 1, the present embodiment comprises drainage tube 1, soft metal nook closing member 2 and air bag 3, is provided with air intake duct 11 in the tube wall of described drainage tube 1, and soft metal nook closing member 2 is arranged in the air intake duct 11 of drainage tube 1, the head end of drainage tube 1 is provided with side pore 12, and air bag 3 is arranged on side pore 12.
The end of drainage tube 1 is provided with irrigation channel 13, and described irrigation channel 13 and drainage tube 1 form y-type structure.Irrigation channel 13 is for rinsing.
Drainage tube 1 length is 25cm, can meet general neurosurgery demand.
The head end of soft metal nook closing member 2 is provided with conical blunt nosed 21, and end is provided with draw ring 22, can be according to different operative site random-shapings in art, and the inner table of skull so that drainage tube 1 is fitted to greatest extent, avoid injured brain tissue.
During use, until drainage tube 1 insert angle and the degree of depth satisfied after, air bag 3 inflations, effectively fixedly drainage tube 1 avoid under slippage, secondary dura mater or epidural hematoma transparent, can make all the time drainage tube 1 laminating cerebral dura mater, avoid brain to open again rear drainage tube 1 and thrust cerebral tissue simultaneously.
