Abstract
The utility model relates to the technical field of medial instruments, in particular to an infant tong-type nasal dilator, characterized in that a right half tong and a left half tong are connected into a tong body (1) by a hinge pin (2), the front portion of the tong body (1) comprises nasal upper and lower lobes (3), the rear portion comprises tong handles (4), and a locking mechanism (5) and an elastic resetting mechanism (6) are arranged on the tong handles (4). The utility model has simple structure, can be used conveniently, and meets the physiological structure characteristics of infant nasal cavity, in addition, the nasal dilator can be automatically locked so as to keep the opening of the nasal dilator during the use, thereby lowering the labor intensity of the doctor during operation and reducing the damage to the nasal cavity tissue.
Description
Technical field
This utility model relates to technical field of medical instruments, is specifically related to a kind of infant jaw type nasal speculum.
Background technology:
Nasal speculum is a kind of medical apparatus and instruments of routine, generally is made up of left sheet, right sheet, jump ring and connecting axle.Nasal speculum is usually used in nasal cavity routine examination, neuroendoscopy operation and nasal endoscopic surgery.
The infant nasal cavity is narrow and small, organize rapid wear, and existing nasal speculum can't satisfy the operation needs, during as the capable pituitary adenoma resection operation of per nasal-butterfly approach, existing nasal speculum can't in divide the position, it is prominent very easily to open the internal carotid artery gallery, tune before the damage.
The utility model content:
For overcoming the deficiencies in the prior art, this utility model provides a kind of infant jaw type nasal speculum.
The technical scheme that this utility model technical solution problem is adopted is a kind of infant jaw type nasal speculum, connect into vice body by the right side half pincers, a left side half pincers by joint pin, the front portion of vice body is the nose upper and lower lobes, and the rear portion is provided with retaining mechanism and flexible restoring organ for pincers handle, pincers handle.
In one embodiment, described retaining mechanism is pulled and is locked reed by sector rack, strap wrenches tooth and forms, sector rack is connected on the pincers handle of a left side, band plate hands tooth plate is hinged on the pincers handle of the right side, and locking reed group is connected on the right pincers handle and can flexibly band plate hands tooth plate be engaged on the optional position of sector rack.
In one embodiment, described flexible restoring organ is spring or jump ring.
In one embodiment, the length of described nose upper and lower lobes is 1-5cm.
In one embodiment, the outside of described pincers handle is provided with some non-slip process.
This utility model is simple in structure, easy to use, is suitable for the physiological structure characteristics of infant nasal cavity, and automatically lock and make this nasal speculum in use keep the folding degree, has reduced the labor intensity of doctor in the art and to the damage of nasal cavity tissue.
Description of drawings:
Fig. 1 is the overall structure sketch map of infant jaw type nasal speculum one more excellent example.
The specific embodiment:
Below in conjunction with the drawings and specific embodiments, further illustrate this utility model.Should be understood that these embodiment only to be used to this utility model is described and be not used in the restriction scope of the present utility model.
As shown in Figure 1, this utility model infant jaw type nasal speculum connects into vice body 1 by the right side half pincers, a left side half pincers by joint pin 2, the front portion of vice body 1 is a nose upper and lower lobes 3, the rear portion forms a jaw type nasal speculum for pincers handle 4, pincers handle 4 is provided with retaining mechanism 5 and flexible restoring organ 6 with this.The effect of retaining mechanism 5 is these jaw type nasal speculums that are locked after the exposure surgical field of view.Retaining mechanism 5 pulls 5b by sector rack 5a, strap wrenches tooth and locking reed 5c constitutes.Sector rack 5a is connected on the pincers handle 4a of a left side, and band plate hands tooth plate 5b is hinged on the pincers handle 4b of the right side, and locking reed 5c is connected in the optional position that right pincers handle 4b went up and can flexibly band plate hands tooth plate 5b be engaged on sector rack 5a.Described flexible restoring organ is a jump ring 6, is connected in left and right pincers handle 4a/4b.The length of described nose upper and lower lobes 3 is 1cm.
The profile of tooth of sector rack 5a and band plate hands tooth plate 5b can be made ratchet and ratchet shape respectively; left and right pincers handle 4a/4b can only be drawn close relatively and can not separate relatively; but pulling strap wrenches tooth plate 5b can make it overcome the coupling mechanism force of locking reed 5c and take off with sector rack 5a tooth; left and right pincers handle 4a/4b can freely separates or draws close, thereby makes nose upper and lower lobes 3 draw close or expand out.This retaining mechanism 5 has the function that can automatically lock after expansion is opened, thereby reason is by drawing close relatively away from the position nose upper and lower lobes 3 to be expanded nasal cavity when opening left and right pincers handle when special this jaw type nasal speculum of hands, band plate hands tooth plate 5b can overcome the active force of locking reed 5c because of the drive that handle 4b is clamped on the right side and regulate the position of engagement automatically, and stop hands to left and right pincers handle 4a/4b pinch active force the time, by the active force of locking reed 5c with sector rack 5a engagement locking.Simultaneously, the nasal cavity tissue also makes left and right pincers handle 4a/4b tighten to the active force of nose upper and lower lobes 3.This retaining mechanism 5 has different characteristics than prior art, can automatically lock, and is still more convenient, and retaining mechanism that retaining mechanism of the prior art for example is made of fan-shaped frid and fishbolt or the like is applicable to this nasal speculum too.
Scope of the present utility model is not subjected to the restriction of described specific embodiments, and described embodiment also comprises the method and the component of functional equivalent only as the single example of illustrating this utility model various aspects in this utility model scope.In fact, except content as herein described, those skilled in the art can easily grasp multiple improvement of the present utility model with reference to above description and accompanying drawing.Described improvement also falls within the scope of appended claims.
