Abstract
The utility model discloses a kind of ostium of maxillary sinus gag, it is the hinged composition of fixed handle and flexible handle, fixed handle front end is fixed with stay pipe, the head of stay pipe connects the afterbody of the expansion apparatus that can outwards expand, the head of expansion apparatus is fixed on slip-on head, slip-on head is connected with the head of flexible handle by the drag-line in stay pipe, and this utility model has simple, easy to operate, the safe feature of use.
Description
Technical field
This utility model belongs to technical field of medical instruments, especially relates to a kind of ostium of maxillary sinus gag.
Background technology
Maxillary sinus is positioned at the below of human face's eye socket, its opening is positioned at nasal cavity middle nasal meatus, during findings in endoscopic sinus surgery of being expert at, the open natural opening expanding maxillary sinus of usual needs, be generally adopt polyp forceps to sting hole mouth sclerotin and mucosa to cut at present, it is more inconvenient that this mode operates, and cut through in journey stinging, if angle is grasped bad, than being easier to, damage being caused to the position such as eye socket and lachrymal sac, causing more serious postoperative complication.
Summary of the invention
The purpose of this utility model provides a kind of in the deficiency with improvement prior art and uses simple, easy to operate, safe ostium of maxillary sinus gag.
The purpose of this utility model realizes like this, a kind of ostium of maxillary sinus gag, it is the hinged composition of fixed handle and flexible handle, be characterized in that fixed handle front end is fixed with stay pipe, the head of stay pipe connects the afterbody of the expansion apparatus that can outwards expand, the head of expansion apparatus is fixed on slip-on head, and slip-on head is connected with the head of flexible handle by the drag-line in stay pipe.
In order to realize the purpose of this utility model further, can be stay pipe head upwards to bending, form 60-80 degree angle.
In order to realize the purpose of this utility model further, the middle part of can be described expansion apparatus be two connecting rods is hinged, and the other end of two connecting rods is hinged with slip-on head, stay pipe respectively.
In order to realize the purpose of this utility model further, can be described expansion apparatus be that slip-on head is connected with one end of limited post, the other end of limited post is connected with drag-line, and the two ends being positioned at the elastic expansion silk of limited post outer surface are connected with slip-on head and stay pipe respectively.
Compared with the prior art this utility model has following distinguishing feature and good effect: this utility model adopts fixed handle front end to be fixed with stay pipe, the head of stay pipe connects the afterbody of the expansion apparatus that can outwards expand, the head of expansion apparatus is fixed on slip-on head, slip-on head is connected with the head of flexible handle by the drag-line in stay pipe, this device stay pipe head is goed deep into maxillary sinus nature Dou Kou, drag-line is driven by flexible handle, slip-on head is pulled to move backward by drag-line, extrusion expansion device, expansion apparatus is outwards expanded, then expansion apparatus is involved, thus realize the object of expansion ostium of maxillary sinus, simple to operate, easy to use, damage can not be caused to organ near hole mouth, stay pipe head, upwards to bending, form 60-80 degree angle, is applicable to the opening angle of ostium of maxillary sinus, is convenient to placement operation, expansion apparatus adopts expansion apparatus link-type or elastic expansion wire form, the needs under different surgery situation can be applicable to, adopt link-type when needing tension force larger, use when the applicable needs tension force of elastic expansion wire form is less, its limited post ensures that elastic expansion silk can only outwards expand.
