In the prior art, the operation is troublesome, and the operation effect is poor when the pair of nasal endoscope surgery scissors is used for cutting off the perforating cartilage. The pair of nasal endoscope rear cutting scissors comprises a fixed handle, and a movable handle connected on the fixed handle. The scissors is characterized by further comprising a connecting plate, a setscrew, a push rod, a forceps rod, a push rod sliding seat and a forceps holder, wherein one end of the connecting plate is fixed on the fixed handle, the other end of the connecting plate is fixed on the push rod, one end of the forceps rod is fixed on the fixed handle, a push rod chute is arranged on the forceps rod, the push rod sliding seat is arranged in the push rod chute and is fixed on the push rod; and a forceps holder bone gouging tooth is arranged at the front end of the push rod, the bottom of the forceps holder is fixed on the push rod by the push rod fixing pin, the bottom end of the forceps holder is fixed on the forceps rod by a forceps holder fixing pin, and the forceps holder and the forceps holder bone gouging tooth are matched. The pair of nasal endoscope rear cutting scissors has the advantages of being reasonable in structural design, convenient for use, safe and reliable in performance, and good in operation effect.

Description

Cutting scissors behind the nasal endoscope

Technical field

This utility model relates to cutting scissors behind a kind of nasal endoscope, is exclusively used in the cartilaginous tissue in the excision nasal sinuses when the treatment nose diseases, belongs to a kind of medical device technology machinery that is used for the treatment of the human body facial disease.

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, causes nose diseases, as cartilage proliferation, in the process of treatment nose diseases, need be with the cartilage proliferation excision of nasal cavity, this type of performs the operation fine and smooth, needs to use special-purpose instrument.Prior art is to carry out the cartilage proliferation excision with the operation on nasal sinus shears, and operation is used and do not matched, and the operation trouble 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 easy to use, performance is safe and reliable, cutting scissors behind the good nasal endoscope of surgical result.

The technical scheme in the invention for solving the above technical problem is: cutting scissors comprises fixed handle behind this nasal endoscope, flexible handle and handle attaching nut, described flexible handle is connected on the fixed handle by the handle attaching nut, its characteristics are: also comprise connecting plate, fixed screw, push rod, claw beam, the push rod slide, clamp, push rod steady pin and clamp steady pin, one end of described connecting plate is fixed on the fixed handle by the handle attaching nut, the other end of this connecting plate is fixed on the push rod by fixed screw, one end of described claw beam is fixed on the fixed handle, this claw beam be positioned at push rod under, have the push rod chute on the described claw beam, described pusher slide seat is arranged in the push rod chute, and this push rod slide is fixed on the push rod; The front end of described push rod has clamp and stings the bone tooth, and the bottom of described clamp is fixed on the push rod by the push rod steady pin, and the bottom of this clamp is fixed on the claw beam by the clamp steady pin, and described clamp and clamp are stung the bone tooth and be complementary.

One end of claw beam described in the utility model is fixed by welding on the fixed handle.

The medium position of claw beam described in the utility model has the push rod chute.

This utility model compared with prior art has the following advantages and effect: have clamp at the front end of push rod and sting the bone tooth, in operation is used, cutting scissors penetrates human body nasal cavity lesions position, and clamp is clamped the cartilage bone, the pulling flexible handle, push rod promotes clamp, and clamp bites away inferior bone.Designed clamp and clamp are stung the bone tooth, are similar to a toothed chopper, and in the operation application process, the bone that clamp is clamped growth is inferior, it can arbitrarily not come off, and it is effective to sting bone, and the surface is cut very smooth like cutter.

It is big that the designed push rod of this utility model promotes clamp system strength, and the healthcare givers is in the operative treatment process, and clamp clamps the cartilage bone, and general ossa articularia is inferior can both to be bitten away easily, uses flexibly performance safety, reliable.

This utility model can adopt metal material to make, and can clean and high-temperature sterilization.Of the present utility model simple in structure, reasonable in design, control is flexible, good operation effect.
