Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to an anterior rhinoscope with a spreader function.
Background
The front rhinoscope examination is an examination mode commonly used by outpatient doctors in otorhinolaryngology, namely the nostrils are supported by using the forceps like east and west, so that the conditions in the nasal cavity can be clearly seen, the parts which can be seen under the front rhinoscope comprise nasal mucosa, nasal vestibules, nasal septum, inferior turbinate, nasal secretion and the like, generally speaking, the front rhinoscope is used for expanding the nostrils, and meanwhile, the nose hair can be prevented from blocking the visual field, and the front rhinoscope examination mainly plays a screening role.
The front rhinoscope examination method is that a doctor holds the front rhinoscope by hands, pinches the joint of the front rhinoscope by a thumb and a forefinger, places one handle on the palm center of the hand, holds the other handle by the other three fingers, and extends the front rhinoscope with two closed leaves and the bottom of the nose into the nasal vestibule in parallel to slightly open the nasal vestibule, and the doctor needs to pay attention to the fact that the front rhinoscope cannot enter too deep so as to avoid causing pain or injuring the mucosa of the nasal septum to cause bleeding symptoms. The two leaves can not be completely closed when the rhinoscope is taken out, so that the phenomenon that the nose hair is clamped to cause pain is avoided, and the color, the hypertrophy and the like of the mucous membrane should be taken care during the examination.
However, the existing front rhinoscope has the following defects in actual use:
firstly, the expansion stability is poor, because when a doctor expands the nostrils of a patient by using the front rhinoscope, the current holding state (including the force for holding the front rhinoscope and the direction of the front rhinoscope) needs to be kept by the hand holding the front rhinoscope, however, the change of the holding force may occur in the hand holding the front rhinoscope due to other unexpected conditions, so that the size of the nostril of the patient is expanded by the front rhinoscope;
second, only one nostril can be dilated at a time, and the conventional anterior rhinoscope can only dilate one nostril at a time, which affects the speed of the doctor in the overall examination of the patient (the overall examination refers to performing the anterior rhinoscope examination on both nostrils of the patient);
thirdly, the use is inconvenient, when the traditional anterior rhinoscope is used, the doctor needs to hold the anterior rhinoscope with a hand, pinch the joint of the anterior rhinoscope with a thumb and a forefinger, place one handle on the palm of the hand, hold the other handle with the other three fingers, extend the anterior rhinoscope with two closed leaves and the bottom of the nose into the nasal vestibule in parallel and open lightly, and pay attention to the too deep that the anterior rhinoscope can not enter (so as to avoid causing pain or damaging nasal septum mucosa to cause bleeding symptoms) and the tight double leaves that can not be closed when taking out the rhinoscope (so as to avoid causing pain due to clamping nasal hair);
fourthly, the safety is not good, when the doctor uses the front rhinoscope to prop open the nostrils of the patient, the head of the patient may shake suddenly due to discomfort or other environmental factors, and at the moment, the front rhinoscope in the doctor's hand may extend into the nasal cavity of the patient excessively, thereby causing injury to the patient.

The side wall of the stay bar 2 is provided with a bar-shaped guide groove 12 which is matched with the limit shaft 11 and runs through the bar body of the stay bar 2, the stay bar 2 is movably installed on the limit shaft 11 through the bar-shaped guide groove 12, the bolt body of the tightening bolt 13 is screwed in the first screw groove 10, and the bottom of the tightening bolt 13 is provided with a first rotating groove 14 matched with the limit shaft 11 along the central axial direction thereof.
A pair of biting blocks 22 are symmetrically arranged on the left and right of the inner side of the mouthpiece 1, and the upper and lower surfaces of the biting blocks 22 are respectively provided with an anti-slip bulge 23 which is uniformly distributed, so that a patient can more comfortably and reliably hold the mouthpiece 1 in the mouth.
The ventilation tube 4 is made of hard material which meets the medical standard.
All seted up damping groove 24 on the lateral wall of 4 one ends of scavenge pipe are kept away from to hornblock 5, the terminal of 6 both ends lever arms of U type pole and the one end that is close to each other all fixed damping head 25 that is equipped with and damping groove 24 matches make U type pole 6 can chew 1 relatively in the turned angle allowed band and hover of arbitrary angle like this, and the middle part body of rod of U type pole 6 is straight form to the body of rod cross-section of U type pole 6 is the rectangle.
The length value of the limiting shaft 11 is equal to the sum of the distance value between the inner side walls of the two lug bosses and the thickness value of one lug boss along the central axis direction of the first thread groove 10, the radius value of the limiting shaft 11 is 0.4 times of the radius value of the first thread groove 10, and the limiting shaft 11 is arranged on the lug bosses which are parallel to each other and are close to the two hinge seats 9.
The length of the strip-shaped guide groove 12 is 0.9 times that of the support rod 2, and the center of the strip-shaped guide groove 12 coincides with that of the support rod 2, so that the support rod 2 can have a sufficient range of advance and retreat with respect to the hinge base 9 to accommodate different patients because the distance from the nose to the mouth of different patients is different.
The stay bar 2 is made of hard materials meeting medical standards, and the thickness value of the stay bar 2 is 1.5 mm, so that the blocking of the nasal cavity of a patient is reduced as much as possible while the nostril of the patient can be propped open by the stay bar 2.
The rod head of the screw rod 19 is also provided with a retaining piece 26 matched with the second rotating groove 21, so that the reliability of the synchronous component 3 in operation can be further improved.
When in use:
firstly, a doctor looses a jacking nut and restores the synchronizing assembly 3 and the U-shaped rod 6 to an initial state (the initial state refers to a state that the synchronizing assembly 3 is completely unexpanded, a central axis of the U-shaped rod 6 is vertical to the ground, and the state of the U-shaped rod 6 and the synchronizing assembly 3 shown in figure 1 in the attached drawings of the specification is the initial state);
secondly, the doctor respectively adjusts the depth values of the two support rods 2 extending into the nasal cavity of the patient to be proper, and then adjusts the jacking nut to ensure that the support rods 2 are reliably fixed on the hinged support 9;
thirdly, the doctor rotates the U-shaped rod 6 appropriately, so that the support rod 2 can enter the nasal cavity of the patient vertically to the nostril of the patient;
fourthly, the doctor adjusts the screw rod 19 to increase the distance between the two sliding blocks 8, so that the two nostrils of the patient are simultaneously propped open by the support rods 2;
fifthly, examining two nasal cavities of the patient by a doctor;
sixthly, when the examination is finished, the doctor only needs to adjust the screw rod 19 to reduce the distance between the two sliding blocks 8 until the nostrils of the patient restore to the state before being propped open, and simultaneously loosens the jacking nut to enable the stay bar 2 to withdraw from the nasal cavity of the patient automatically due to gravity, and finally takes the mouthpiece 1 out of the mouth of the patient.
