Description

Opener

Technical field

The utility model relates to medical instruments, especially for prying open the opener of patient's maxillary and mandibular teeth.

Background technique

Some Special patients are tightly grited one's teeth passs when falling ill, when need to be open treat when, the maxillary and mandibular teeth of patient need to be pried open.It is existing Some medical mouth gags are the jaw type and spiral of dehiscing, and jaw type of dehiscing is made of metal material.Since opener rack is rigidly strong, And the opening mode prized firmly above and below is taken, and it is often that the tooth sled of patient is bad, new damage is caused to patient.It is spiral to use Taper, tapered outer circumferential surfaces are threaded.The hatch method of above two opener pries open the upper and lower jaw of patient using physical constraints Tooth.Operationally there is larger difficulty, causes accidental injury probability big patient.

Jaw-jerk reflex and swallowing reflex, referred to as K can be induced by the discovery K point stimulation of thousand branch of Japanese language therapist island Point stimulus method.K point is also K-poin, positioned at the central location of the height of retromolar triangle, palatoglossal arch and pterygomandibular, is located at two The rear position of dental floss intersection point, actually one is recessed herein, and the K point stimulus method is by thousand branch of Japanese language therapist island It foundes, since the first letter of the English translation name Kojima of thousand branch of island is " K ", therefore is named as K point.The stimulation of K point is direct It is stimulated for oral cavity, especially for the patient that some cognitive abilities, ability to model are poor, his operability and safety The higher and better effect of property；With easy to operate, and Noninvasive therapy, the advantages that patient compliance is high, therefore it is existing clinically It is used widely.

At present when actual clinical operates, stimulated with finger based on, medical staff wears gloves, and finger is stitched from tooth and buccal mucosa Gap enters stimulation K point and cooperates traditional spiral type mouth opening device to strut patient's mouth to realize after patient stimulates opening, from And convenient further operation.But this method is easy to be bitten finger by patient, and there are cumbersome, stimulation and opener operations Cooperation linking is more difficult, after the completion of stimulation, fills in opener not in time, patient is again silent, failure easy to operate.

Summary of the invention

The present utility model purpose: to overcome defect of the existing technology, the utility model provides a kind of utilization K point Stimulus method implements opening manipulation, and structure is simple, the opener of simple and safe operation.

To achieve the above object, the utility model provides following technical solution:

A kind of opener, including opener ontology, it is characterised in that: the opener ontology includes oral cavity expanding handle, mouth The front end that chamber struts handle, which is equipped with K point, stimulates end, and the end of K point stimulation end is arc-shaped, and the rear end of oral cavity expanding handle is equipped with Hand-held part.

By using above-mentioned technical proposal, when operation, hold hand-held part by K point stimulate end from tooth and buccal mucosa gap into Enter to stimulate K point, when patient dehisces, take advantage of a situation by oral cavity expanding handle be directly plugged between patient's teeth space realize dehisce to support, avoid Patient is silent again；Instead of security risk existing for existing finger manipulation, while stimulating in K point and can connect with operation of dehiscing Continuous, more closely, operation is more simple, and single medical staff can be completed for linking.

Preferably, the oral cavity expanding handle is the taper being gradually increased to the back-end by front end, taper oral cavity expanding handle periphery Face is provided along its length spiral bar.It is under structure design, the design of oral cavity expanding handle is tapered and with spiral bar, realize spiral shell Rotation advanceable directly struts patient's oral area, operates more simple and convenient.

Preferably, K point stimulation end is center axis and oral cavity expanding handle central axis is in the curved of angle cooperation Head.Under structure design, it is more preferably and more easy to be sharp into assassinating to K point to be convenient for K point stimulation end, so that operation is more convenient, Especially in the case where oral cavity expanding handle is the conical design being gradually increased to the back-end by front end, under bend design, it can guarantee to K point Stimulation applications.

Preferably, the central axis of K point stimulation end and oral cavity expanding handle central axis in angle be 90 to 160°.Under structure design, it is convenient for K point stimulation end more preferably and more easy to be sharp into assassinating to K point, so that operation is more square Just.

Preferably, the opener ontology is using medical-grade plastics material molding one.It is easy to process under structure design, Good integrity.

The utility model is further described with reference to the accompanying drawing.

Detailed description of the invention

Fig. 1 is the utility model specific embodiment opener perspective view；

Fig. 2 is the utility model specific embodiment opener structural schematic diagram.

Specific embodiment

Referring to attached drawing 1 and attached drawing 2, a kind of opener disclosed by the utility model, including opener ontology, the opener Ontology includes oral cavity expanding handle 1, and the front end of oral cavity expanding handle 1, which is equipped with K point, stimulates end 2, and the end 21 of K point stimulation end 2 is in Arc-shaped (more soft, to avoid damaging patient), the rear end of oral cavity expanding handle 1 is equipped with hand-held part 3.

The oral cavity expanding handle 1 is the taper being gradually increased to the back-end by front end, and 1 outer peripheral surface of taper oral cavity expanding handle is along it Length direction is equipped with spiral bar 11.The design of oral cavity expanding handle is tapered and with spiral bar, realize that screwfeed formula will directly be suffered from Person's oral area struts, and operates more simple and convenient.Certainly it is used as the feasible scheme of the utility model, oral cavity expanding handle can be directly circle Mast is only used for the supporting role after patient dehisces, and carries out further operating using existing screw-wedge, but directly will Oral cavity expanding handle is designed to that screw-wedge structure is formed, operationally more convenient.

Further, K point stimulation end 2 is that center axis and oral cavity expanding handle central axis make an angle alpha cooperation Elbow.Under straight design, K point stimulates the stimulation of end inconvenient, is designed into elbow, and K point is enabled to stimulate end More readily K point is swashed into assassinating so that operation is more convenient, especially oral cavity expanding handle be by front end to the back-end gradually Under the conical design of increase, under bend design, it can guarantee the stimulation applications to K point.

It is 90 to 160 ° that the central axis and 1 central axis of oral cavity expanding handle of K point stimulation end 2, which make an angle alpha,.More It is 125 ° to 135 ° designs for preferred angle α, angle is controlled, human oral cavity can be preferably adapted to, stimulates end convenient for K point It is more preferably and more easy to be sharp into assassinating to K point, so that operation is more convenient.

To be easy to process, the opener ontology is using medical-grade plastics material molding one.

The opener operating method of the invention are as follows: when operation, hand-held hand-held part glues K point stimulation end from tooth and cheek Film gap enter stimulation K point, when patient dehisces, take advantage of a situation by oral cavity expanding handle be directly plugged between patient's teeth space realize dehisce to prop up Support, avoid patient silent again, laggard screwfeed realization patient's oral area is further strutted；Instead of existing finger exercise Make, it is safer reliable, while K point stimulate and with dehisce to operate that cooperating is more convenient, and more closely, operation is more for linking To be simple, single medical staff be can be completed.
