Abstract

The utility model pertains to head bearing support nose mirror which is a medical appliances that are usually used in rhinology. The utility model is characterized in that: the utility model can be directly fixed and supported by being worn on the head of patients. The movement of the patient is consistent with the device free from the restriction of environment. When checking the nasal cavity, the utility model changes the shortages of traditional nasoscope and is needless of being fixed by the hands of operator, therefore, the utility model greatly improves work efficiency and accuracy. The utility model is convenient to use, small in size, stable and durable, and is free from the limit of the body position and direction. Each component is demountable and can be repaired. The used materials are harmless to human body and can be sterilized chemically and physically.

Description

Wear-type supports asoscope

1, affiliated technical field

This utility model is a kind of medical apparatus and instruments, is one of nose section of hospital apparatus commonly used.It can fixed support in nasal cavity inspection, treatment, operation, especially can be directly fixed on patient head.

2, background technology

At present, the asoscope that uses in the inspection of hospital clinical nose section, treatment and the operation mostly is handle type, and in operating, the operator only can carry out with one hand, brings many restrictions to the operator, has increased the difficulty of operation.In this case, some easy asoscopes that support also occur, can in use play certain supporting role, but in actual use, because of its making clumsy, very flexible, it is not firm to support, and is subjected to shortcomings such as operating environment restriction, makes clinical use be subjected to very big restriction.

3, summary of the invention

In order to overcome existing asoscope shortcoming and drawback in use, this utility model provides a kind of wear-type to support asoscope, and this asoscope can not only fixedly secure support, and easy to use flexible, is not subjected to the operating environment condition restriction.Characteristics and the advantage of this utility model in actual use of clinical nose section is: can be directly fixed on patient head, be not subjected to the operating environment condition restriction, in the operating process, the change of patient's head position can be harmonious with device, need not to adjust repeatedly angle, make operation quick more freely; Can fixed support, solved the drawback of using one-handed performance in traditional asoscope operation, but operator's both hands operate, increase work efficiency greatly and accuracy; This device is easy and simple to handle, and is easy to carry, and the volume exquisiteness is used flexibly, and is with low cost, stablizes durablely, is better than previously other asoscope of nose section of hospital; This utility model material therefor is all harmless to human body, each part detachable, maintenance and chemically-resistant sterilization and physical sterilization.

5, the specific embodiment

The picture of three secondary figure reflection overall pictures of the present utility model and major part different angles, digital nominal unanimity among the figure.This utility model has four parts and forms: headband (4-1), and expansion link (3-1), universal joint (2-1), fixedly asoscope (1-1) is seen accompanying drawing.Headband (4-1) is made up of head circle (4-5), hold-down nut (4-3), slide opening (4-4) etc.; Section header circle (4-5) diameter that hold-down nut (4-3) is adjustable, slide opening (4-4) links to each other with expansion link, and screw (4-2) is arranged on its hole, adjustable and retractable bar (3-1) length.Expansion link (3-1) is made up of the straight-bar body and the two ends of band chute, and expansion link (3-1) end is formed an end of universal joint (2-1), and the other end is the nut (3-2) that prevents slippage, and the chute on the straight-bar communicates with headband slide opening (4-4).Fixedly asoscope (1-1) is by direction selector bar (1-2), with deciding screw (1-3), fixed body (1-4), two leaf working heads (1-5) are formed, direction selector bar (1-2) end is formed an end of universal joint (2-1), and the other end links to each other with fixed body (1-4), and wherein a leaf is movable for two leaf working heads (1-5), its openings of sizes scalable, and control by the hold-down screw (1-3) on the fixed body (1-4).Whole device is reasonable in design, and is easy to use, flexible.

When wear-type supports the asoscope use, headband is worn the head in the patient, fixedly slide opening with fixed firm, is adjusted length of telescopic bar with headband forward, make working head and patient's prenaris in same level, and the straight nasal cavity that struts of energy, regulate the active operation head, prenaris is strutted reach desirable amount, regulate fixedly asoscope angle more as required, up to obtaining satisfied visual field effect.Fixedly associated screw is operated treatment accordingly.

Claims

1. asoscope, can be fixed in patient head, play fixed supporting role, be called wear-type and support asoscope, by headband, expansion link, universal joint, fixedly asoscope four parts are formed, it is characterized in that: headband is fixed in patient head, and expansion link one end links to each other with slide opening on the headband, the expansion link other end links to each other with universal joint one end, and the universal joint other end links to each other with direction selector bar on the fixing asoscope.Fixedly the prenaris of putting into patient of two leaf working heads on the asoscope struts work.

2. according to right 1 described asoscope, it is characterized in that: fixedly asoscope can be regulated direction by universal joint, regulates length by expansion link, headband fixing down can firm fixation, the work of capable of expansion and contraction, flexible coordination.

3. according to right 1 described asoscope, it is characterized in that: when fixedly two leaf working heads on the asoscope were worked, its openings of sizes was regulated as required, and its openings of sizes can be fixed by the hold-down screw on the fixed body after regulating.
