Detailed Description

First, the design of the present invention is designed originally, and in the actual gastroscopy work, medical staff often encounters a patient who obstructs the endoscopy due to the limited opening. The reasons for the restricted stoma are such as: 1. temporomandibular joint disorder syndrome; 2. temporomandibular joint rigidity; 3. inflammation: pericoronitis of the wisdom tooth, maxillofacial infection, osteomyelitis of the mandible and the like can all cause mouth opening restriction; 4. trauma: the mouth opening of a patient is limited due to the fact that masticatory muscle spasm is caused by mandibular fracture, zygomatic arch and zygomatic bone fracture press coracoid process and the like, and the mouth opening of the patient is limited, so that a bite or mouth pad for an endoscope cannot be placed, and gastroscopy cannot be finished.

It is often necessary to use a mouth gag to assist the opening to the bite or mouth pad for the endoscope, which is a cumbersome operation and may damage the teeth, gums, mandible, etc. of the patient. Through clinical practical application, observe that ordinary mouth gag can assist the opening, nevertheless can not provide the support passageway for the scope, the bite-line for the scope can provide the support passageway for the scope, nevertheless does not possess the opening function, can't directly place to the difficult person of opening one's mouth. For solving this clinical difficulty, the utility model designs an oral cavity strutting arrangement is used in scope inspection that both had the opening function, can provide the support channel again for the scope, has protection tooth, gum function when this strutting arrangement assists the open-ended.

The device is particularly a mouth gag for an endoscope, and the structure and the working principle of the mouth gag for the endoscope are detailed below:

as shown in fig. 1-3, the principle of the overall structure of the present invention is first explained, the present invention adopts a manner that two handles 1 are hinged, for easy understanding, two ends of the handle 1 are defined as an active end and a passive end, and when one end is pressed, the other end is opened, and vice versa. The active end of the handle 1 is opened by pressing down the active end of the handle 1, and when the passive end of the handle 1 is pressed, the active end is opened, if the limitation on the active end can be realized through a certain structure, especially the limitation on the opening of the active end, the side enables the passive end to resist external force when the passive end is pressed, and the opening and fixing effects on the passive end are realized. Based on the design idea, the utility model discloses a structure has been designed.

The utility model discloses a two handles 1 and the locking bolt 2 that is located handle 1 end, and the middle part position of two handles 1 is articulated, and handle 1 includes head 101 and arm 102, and this handle 1 is foretell two handles 1 promptly, and its head 101 is foretell passive end promptly, and its arm 102 is foretell active end promptly, and the in-process that two arm 102 were opened, head 101 can be closed simultaneously, vice versa, and locking bolt 2 is the structure that the aforesaid was used for restricting the active end promptly. In order to realize the hinge joint of the two handles 1, a hinge shaft 4 for hinge-jointing the two handles 1 is penetrated and connected at the hinge joint position of the two handles 1.

In order to combine the locking bolt 2 with the handle 1, it is necessary to open a locking hole 5 at the end of the arm 102, then insert the locking bolt 2 into the two locking holes 5, and the locking bolt 2 further comprises a screw 201 and a nut 202, two fins 203 convenient for people to pull manually are fixed on the outer side wall of the nut 202, a cap with a diameter larger than that of the locking hole 5 is fixed on the head 101 of the screw 201, this structure can limit the two arms 102 between the cap of the locking bolt 2 and the nut 202 at the same time, and by rotating the nut 202, the distance between the nut 202 and the cap is changed, thereby restricting the size of the opening of the two arms 102, and further restricting the minimum closing degree of the head 101 of the handle 1, so that the handle can still maintain a certain opening size when forced, it should be noted that the connection mode of the nut 202 on the screw 201 is a threaded connection, in order to achieve a better screw-on locking while avoiding problems with disengagement during use, a fine-pitch threaded connection is preferred here.

In order to leave the support channel for the scope, set up scope passageway 3 at the central point of handle 1, its specific position of seting up runs through to the top of handle 1 head 101 from the bottom of articulated shaft 4, so, can stretch into the patient oral cavity with the scope through this scope passageway 3, avoided in the conventional product because of not having scope support channel, and the condition that the scope that leads to is pushed down by the patient.

The above explains the mode of structure and locking bolt 2 design that scope passageway 3 was seted up, and the problem that leads to immediately is, need remove in certain space range during the scope inspection, and the position of locking bolt 2 has just in time sheltered from the scope action in scope passageway 3, so just caused the interference of locking bolt 2 to the scope, in order to solve this problem, the utility model discloses design into the S type with arm 102 'S structural style to make locking bolt 2 avoid scope passageway 3' S central line position (the position that the gastroscope probably exists), avoided the interference of locking bolt 2 to the gastroscope.

Through the structure, the mouth gag has the functions of opening and fixing and holding simultaneously, and in order to optimize the structure and combine practical use considerations, partial structural characteristics are added on the basis of the structure, specifically comprising the following steps 1. the cross section of the head 101 of the handle 1 is designed to be flat and trapezoidal, and the cross section is flatter the closer to the top end of the head 101, so that the design mode is convenient for inserting the head 101 of the handle 1 into the oral cavity of a patient; 2. the aperture of scope passageway 3, the position aperture that is close to the head 101 top is little, the position aperture that is close to arm 102 is big, on the one hand because the cross-section at 1 head 101 top of handle is little, do not suitably open the large aperture, on the other hand is along with opening of head 101, the 3 apertures of scope passageway on its top can expand naturally, can not influence in-service use, can also guarantee simultaneously that the intensity on head 101 top can not cut down the material and reduce its use strength 3. the marginal shape on 1 head 101 top of handle is the arc of anastomosing with the teethridge shape, can make head 101 more agree with the profile of tooth like this, be convenient for to the support of patient's oral cavity, be difficult for droing.

Having described the structure and principles between its various parts, the system will now be described in its entirety with reference to the methods and principles of use.

Firstly will the utility model discloses a head 101 inserts in patient's mouth, then manually presses arm 102, is pressing the closed in-process of arm 102, and handle 1 head 101 that is arranged in patient's mouth can open, and then struts patient's oral cavity, struts suitable size, and manual rotating nut 202 locks arm 102, and handle 1's head 101 this moment also can be fixed, plays the effect of fixed stay and fixed oral cavity. Medical staff can then stretch into patient's stomach with the gastroscope through scope passageway 3 oral cavity and carry out the gastroscope inspection, after the inspection finishes, takes out the scope, reverse rotating nut 202 loosens arm 102, along with the relaxation of arm 102, the head 101 of handle 1 is closed gradually, reach suitable degree and directly take out from patient's mouth can.

Above-mentioned technical scheme has only embodied the utility model discloses technical scheme's preferred technical scheme, some changes that this technical field's technical personnel probably made to some parts wherein have all embodied the utility model discloses a principle belongs to within the protection scope of the utility model.
