Abstract
The utility model provides an indirect nasopharyngoscope which can settle a problem that the slipping is easily generated when a holding nasopharyngoscope handle is rotated according to the prior indirect nasopharyngoscope. The utility model provides a technical solution that the indirect nasopharyngoscope comprises a lens and a nasopharyngoscope handle which comprises raised grains. The friction force between the finger and the nasopharyngoscope handle is increased when the nasopharyngoscope is held by an operator. The phenomenon of slipping is prevented. The positioning is accurate and stable when the nasopharyngoscope is used by the operator. The surgery time is greatly reduced.
Description
Technical field
This utility model belongs to medical apparatus and instruments, a kind of indirect nasopharyngeal endoscope that particularly otorhinolaryngologic nasopharynx part is used.
Background technology
The nasopharynx part position is dark and hidden, is the multiple position of nasopharynx disease.At present, the most frequently used inspection means of nasopharynx part are to observe with indirect nasopharyngeal endoscope, it is to be made of camera lens and mirror handle, when observing patient's nasopharynx part, the operator need be with two finger grip mirror handles, and constantly rotate the direction of camera lens, so that see nasopharynx part clearly comprehensively, simple, the easy row of the method, economic, the doctor grasps easily.But because existing indirect nasopharyngeal endoscope mirror handle is a smooth thin bar, the operator is easy to generate slip when rotating with two fingers, make camera lens be not easy to rotate, especially for older doctor, the curable grip of its finger a little less than, more be easy to generate slip, originally inspection had anxiety, was afraid of reaction painful or that feel sick the patient to this kind, if doctor's operating time is long, the patient suffering increases, produce negative feeling, influence the diagnosis of the state of an illness.
Summary of the invention
The utility model proposes a kind of convenient gripping, rotate flexibly nasopharyngeal endoscope indirectly, can solve existing indirect nasopharyngeal endoscope and grip the problem that is easy to generate slip when the mirror handle rotates.
For solving the problems of the technologies described above, this utility model is achieved by the following technical solutions:
A kind of indirect nasopharyngeal endoscope comprises camera lens and mirror handle, wherein, has asperities on the described mirror handle.
Further, this utility model also has following technical characterictic: described asperities can be screw thread.
Further, this utility model also has following technical characterictic: described threaded portion is positioned at mirror handle upper end, and the length of threaded portion is the 1/3-1/2 of whole mirror handle length.
Further, this utility model also has following technical characterictic: described screwed mirror shank diameter is 1.5-2 times of not threaded mirror shank diameter.
Compared with prior art, advantage of the present utility model and good effect are as follows:
1, is carved with asperities on the indirect nasopharyngeal endoscope mirror of this utility model handle, increased when the operator grips the frictional force between finger and the mirror handle, avoided the phenomenon of skidding;
2, the screwed mirror shank diameter of this utility model 1.5-2 that is not threaded mirror shank diameter doubly, general mirror handle is thinner, grip uncomfortablely, the mirror shank diameter of grip portions is increased, can obviously feel laborsaving, comfortable when the operator grips the mirror handle, rotate freely.
This utility model is simple in structure, and is easy to process, and operating time has been shortened in accurate positioning when the operator uses, stable, has greatly guaranteed success rate of operation.
Description of drawings
Fig. 1 is this utility model embodiment one structural representation;
Fig. 2 is this utility model embodiment two structural representations;
Wherein, 1, mirror handle; 1-1, threaded mirror handle; 1-2, not threaded mirror handle; 2, camera lens; 3, screw thread.
The specific embodiment
Below in conjunction with the drawings and specific embodiments this utility model is described in further detail.
Embodiment one, and as shown in Figure 1, the indirect nasopharyngeal endoscope of present embodiment comprises mirror handle 1, camera lens 2, and mirror handle 1 upper end has screw thread 3, and the length of threaded portion is 1/2 of whole mirror handle 1 length.
Embodiment two, as shown in Figure 2, are with embodiment one difference, and this implements screwed mirror handle 1-1 diameter 1.5-2 times for not threaded mirror handle 1-2 diameter, and the length of threaded portion is 1/3 of whole mirror handle 1 length.
During use, grip screwed part on the mirror handle, because screw thread has increased the frictional force between finger and the mirror handle, it is more flexible to make that the operator rotates the mirror handle, thereby can undergo surgery smoothly.
Certainly, this utility model is not limited to be carved with screw thread on the mirror handle, also can carve other decorative patterns on the mirror handle, makes the mirror handle become coarse as long as can satisfy.
The above, it only is preferred embodiment of the present utility model, be not to be the restriction of this utility model being made other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
Claims (4)
1, a kind of indirect nasopharyngeal endoscope comprises camera lens and mirror handle, it is characterized in that: have asperities on the described mirror handle.
