Between the cavity of bar 2 to be connected with movable head 32.Flexible handle 11 tractive bracing wire when fixed handle 12 carries out far and near stretch
23 and drive movable head 32 movable, flexible handle 11 is opened away from movable head during fixed handle 12 32, and flexible handle 11 is near solid
When determining handle 12, bracing wire 23 affects so that movable head 32 closes.Maximum angle between fixing head 31 and movable head 32 can basis
The practical situation of patient and operation needs are designed, and such as its maximum angle can be 30 °-75 °.
According to a kind of detailed description of the invention of the present utility model, as it is shown in figure 1, fixing head 31 and movable head 32 can be phase
The binding clip coordinated mutually.Affect bracing wire 23 that two panels binding clip folding can be made to complete the action of clamp by flexible handle 11.Binding clip
Shape can be designed according to the practical situation of patient, can be such as triangle, hollow out triangle, rim of a cup shape, circle,
The shapes such as hollow out circle, crocodile mouth shape.
According to another kind of detailed description of the invention of the present utility model, as in figure 2 it is shown, fixing head 31 and movable head 32 can also
For the scissors bit cooperated.Affect bracing wire 23 that two panels scissors bit folding can be made to complete the dynamic of shearing by flexible handle 11
Make.The shape of scissors bit can be designed according to the practical situation of patient, such as, can be the shapes such as triangle.Described shears
Head can have radian.
According to the third detailed description of the invention of the present utility model, as it is shown on figure 3, work 3 can also be cutter head.Pass through
Flexible handle 11 affect bracing wire 23 can make cutter head moved cutting action.The shape of cutter head can be rhombus, crescent,
Triangle etc..Described cutter head can have radian.
In order to improve the stability of operation further, between described fixed handle 12 and flexible handle 11, it is provided with angle locking
Structure, for the angle between locking fixed handle 12 and flexible handle 11.It is embodied as according to one of the present utility model
Mode, as it is shown in figure 1, described angle latch-up structure includes that gag lever post 8, described flexible handle 11 have elongated hole, described gag lever post 8
One end is hinged on fixed handle 12, and the other end passes described elongated hole, and described gag lever post 8 surface configuration has multiple stopper slot, institute
State and elongated hole is provided with the clamping block mated with described stopper slot.When the head that works is the binding clip cooperated, binding clip pincers are clamped
After destination organization, make the stopper slot on gag lever post 8 surface mutually lock with the clamping block in the elongated hole of flexible handle 11, can fix
Angle between flexible handle 11 and fixed handle 12, improves the fastness that binding clip accommodates, and prevents the destination organization accommodated from coming off.
The patient of glottis difficult exposure under running into supporting laryngoscope, after using arc visible laryngoscope to expose glottis, can use
Operating theater instruments of the present utility model carries out the process of Vocal cord lesion, thus ensures that under supporting laryngoscope, the patient of glottis difficult exposure obtains
To effective operative treatment, reduce patient and suspend the incidence rate of operation owing to glottis appears dissatisfied.In operation process permissible
More intuitively observed the situation in affected part by photographic head, do not cause the visual field to be obstructed, in patient throat because of blocking of operating theater instruments
Still hands can be smoothed out by the light source that this operating theater instruments carries when situation complexity causes shadowless lamp cannot irradiate or irradiate difficulty
Art.
The use process of larynx operating theater instruments of the present utility model is as follows: the work head of this larynx operating theater instruments and intermediate bar
Enter oral cavity from patient's bicker, along oral cavity, the physiological bending of throat be the most progressively deep to reach into vocal cords level, in view of this practicality newly
The angle of type and length can arrive diseased region easily, and Vocal cord lesion is carried out biopsy or excision, and pathological tissues will not arbitrarily take off
Fall.
Preferred implementation of the present utility model is described in detail above in association with accompanying drawing, but, this utility model does not limit
Detail in above-mentioned embodiment, in technology concept of the present utility model, can be to skill of the present utility model
Art scheme carries out multiple simple variant, and these simple variant belong to protection domain of the present utility model.
It is further to note that each the concrete technical characteristic described in above-mentioned detailed description of the invention, at not lance
In the case of shield, can be combined by any suitable means, in order to avoid unnecessary repetition, this utility model is to respectively
Plant possible compound mode to illustrate the most separately.
Additionally, combination in any can also be carried out, as long as it is not disobeyed between various different embodiment of the present utility model
Carrying on the back thought of the present utility model, it should be considered as content disclosed in the utility model equally.
