Background technology
Nasal sinuses is the organ that the mankind are used to breathe, and tends to suck airborne impurity and antibacterial in the nostril, thereby causes nose diseases, as cartilage proliferation, in therapeutic process, need nasal cavity to organize organ pipe to shear and separate, this type of operation is comparatively fine and smooth, needs to use special-purpose instrument.Prior art is to carry out nasal cavity with the operation on nasal sinus cutter to organize the organ pipe excision, the operation trouble, and the required time of performing the operation is long, does not satisfy ideal surgical effect.
The utility model content
The purpose of this utility model is to overcome above shortcomings in the prior art, and a kind of reasonable in design is provided, and is easy to use, dependable performance, the nasal endoscope staight scissors of good operation effect.
The technical scheme in the invention for solving the above technical problem is: these nasal endoscope staight scissors comprise fixed handle, flexible handle and handle connecting bolt, described flexible handle is connected on the fixed handle by the handle connecting bolt, its characteristics are: also comprise swinging plate, fixed blade, movable scissors, push rod, claw beam, the push rod slide, steady pin, push rod pin and connecting pin, described swinging plate is fixed on the flexible handle, one end of described claw beam is fixed on the fixed handle, the other end of this claw beam is fixed on the fixed blade, one end of described push rod is connected on the swinging plate by steady pin, the other end of this push rod is connected on the movable scissors by push rod pin, have chute on the described push rod, this pushing rod sleeve is contained on the claw beam, described pusher slide cover for seat is contained in the claw beam, this push rod slide is connected in the chute of push rod, described movable scissors is connected on the fixed blade by connecting pin, is provided with the blade of mutual coupling on described fixed blade and the movable scissors.
Swinging plate described in the utility model is fixed by welding on the flexible handle.
One end of claw beam described in the utility model is fixed by welding on the fixed handle.
This utility model compared with prior art has the following advantages and effect: provide a kind of being exclusively used in to shear and the organ pipe of organizing that separates nasal cavity, the art designs of shears folder can be curved structure, reasonable in design, and surgical result is good.
The designed staight scissors shears folder of this utility model can be divided into bending structure and lower bending shape structure, and the art designs of the shears folder of last bending structure and lower bending shape structure is convenient to the doctor and is selected to use according to pathologic condition.During use, as long as hold flexible handle with a firm grip, flexible handle promotes push rod, and fixed blade and movable scissors clamp, and in operation was used, what nasal cavity was cut and be separated in to the shears tongs organized organ pipe effective.
This utility model can adopt metal material to make, and can clean and high-temperature sterilization, and is of the present utility model simple in structure, reasonable in design, and control is flexible, good operation effect.
