In the using process, the invention is mainly divided into two steps of operating the oral cavity opening mechanism 2 to open the oral cavity of a patient and operating the channel flexible outer tube mechanism 4 to bite the gastroscope pipeline.
As shown in fig. 5 and 6, the specific operation steps of the oral cavity distracting mechanism 2 are as follows:
step 100, the thrust conversion box 1 is placed in the oral cavity of a patient, and the oral cavity opening mechanisms 2 at the upper end and the lower end of the thrust conversion box 1 are aligned with the upper jaw teeth and the lower jaw teeth of the patient.
Step 200, the driving tube 3 is integrally loosened and tightened through unidirectional rotation so as to drive the oral cavity opening mechanisms 2 at the upper end and the lower end of the thrust conversion box 1 to be unfolded, and the front row of upper teeth and lower teeth of a patient are occluded into the oral cavity opening mechanisms 2 at the upper end and the lower end.
The linkage tightening disc 34 of the integral elastic driving tube 3 is screwed clockwise in a single direction, so that the linkage tightening disc 34 drives the positioning connecting cylinder 33 and the one-way toothed tube 31 to synchronously rotate, and along with the clockwise one-way rotation of the one-way toothed tube 31, the two driving racks 22 meshed with the outer side of the one-way toothed tube 31 start to move relatively, and therefore the oral cavity opening mechanisms 2 at the upper end and the lower end of the thrust conversion box 1 are driven by the driving racks 22 moving relatively to move relatively and expand.
In the process that the two oral cavity opening mechanisms 2 move relatively and expand, the upper lip and the lower lip of the patient can be positioned between the tooth occlusion tightening mechanism 23 and the oral cavity external limiting plate 24, and at the moment, the teeth at the downward front row of the oral cavity can be occluded into the medical rubber 233 arranged in the V-shaped groove at the top end of the M-shaped downward pressing tightening coupling frame 232 of the tooth occlusion tightening mechanism 23.
When the teeth bite the medical rubber 233, the teeth are firstly clamped into the tooth punching grooves 2332 at the top end of the medical rubber 233, and the tooth punching grooves 2332 are inclined outwards from two side surfaces, so that the teeth can adapt to the teeth with different shapes and play a role in guiding, and the teeth can accurately apply pressure to the bottom end surface of the tooth punching grooves 2332 when being vertically meshed, in addition, when the medical rubber 233 is replaced, the medical rubber 233 is only required to be taken out from the groove at the top end of the downward pressing tightening connecting frame 232, and the plurality of strip-shaped grooves 2331 on the two outer sides of the new medical rubber 233 are clamped in the V-shaped groove at the top end of the downward pressing tightening connecting frame 232.
Along with medical rubber 233 is lasted perpendicular interlock by the tooth, it tightens up the whole deformation that takes place of antithetical couplet frame 232 to drive to push down, the protruding structure of its top V type groove both sides can inwards draw in and extrude the both sides of medical rubber 233, make the occlusion go into medical rubber 233 top tooth washtrough 2332's tooth positive and negative by the medical rubber 233 centre gripping that draws in, the area of contact of medical rubber 233 with the tooth has been increased, cooperate two outer limiting plate 24 laminating patient's lips outsides in oral cavity, make the device whole be fixed in the patient oral cavity, and can correspondingly promote along with patient's bite-force reinforcing steadiness.
And step 300, loosening the oral cavity opening mechanisms 2 at the upper end and the lower end of the thrust conversion box 1 through the elastic ratchet mechanism 32 arranged in the integral elastic driving tube 3, so that the thrust conversion box 1 can be conveniently taken out of the oral cavity of a patient.
The elastic ratchet mechanism 32 mainly pushes the track slider 321 and the one-way engaging ratchet 322 through the slider forward-pushing spring 323, so that the one-way engaging ratchet 322 is elastically abutted to the toothed structure on the outer side of the one-way gear tube 31, and when the one-way gear tube 31 rotates clockwise and one-way, the one-way engaging ratchet 322 sequentially overlaps the toothed structure on the outer side of the one-way gear tube 31 without affecting the clockwise rotation of the one-way gear tube 31.
When the unidirectional gear tube 31 rotates counterclockwise, the unidirectional engaging ratchet 322 abuts against the toothed structure outside the unidirectional gear tube 31, so that the unidirectional gear tube 31 cannot rotate counterclockwise, the external box driving lever 324 outside the thrust conversion box 1 needs to be manually operated to drive the rail slider 321 to move back and extrude the slider forward pushing spring 323, so that the unidirectional engaging ratchet 322 does not contact the unidirectional gear tube 31, and at this time, a patient can drive the two sets of oral cavity opening mechanisms 2 to move relatively to the retracted thrust conversion box 1 when biting, thereby facilitating taking out the thrust conversion box 1.
As shown in fig. 1 to 4, the specific operation steps of the channel flexible outer tube mechanism 4 are as follows:
step 100, the gastroscopic tube is passed through the tunnel flexible outer tube mechanism 4 and inserted into the patient's stomach.
The gastroscope pipeline sequentially passes through the telescopic cylinder 42, the flexible connecting pipe 43 and the fixed cylinder 41 of the channel flexible outer pipe mechanism 4, and a plurality of intra-pipe hinged ridge strips 44 arranged on the inner side of the flexible connecting pipe 43 are occluded on the outer side of the gastroscope pipeline by applying pressure to the flexible connecting pipe 43 subsequently.
Step 200, after the gastroscope pipeline stretches into a proper position, the omnibearing tightening cylinder 5 is rotated in a unidirectional mode to enable the omnibearing tightening cylinder 5 and the integral elastic driving tube 3 to be matched with each other to evenly extrude the channel flexible outer tube mechanism 4, and the channel flexible outer tube mechanism 4 is meshed with the gastroscope pipeline.
By rotating the omnidirectional tightening barrel 5 in both directions, the front end portions of the plurality of hinged tightening fin rods 341 on the linkage tightening disk 34 inside the omnidirectional tightening barrel 5 are inclined in the forward direction or the reverse direction in sequence, and the front end portions of the hinged tightening fin rods 341 inside the omnidirectional tightening barrel 5 are inclined, rotated and furled in along with the inclination of the front end portions of the hinged tightening fin rods 341 inside the omnidirectional tightening barrel 5, so that the outer side of the flexible connecting tube 43 is uniformly extruded by the plurality of hinged tightening fin rods 341, and at this time, the plurality of intra-tube hinged ridges 44 inside the flexible connecting tube 43 start to bite the outer side of the gastroscope tube.
When the omnidirectional tightening barrel 5 rotates clockwise, the front end portions of the hinged tightening fin rods 341 inside the omnidirectional tightening barrel 5 are sequentially inclined in the forward direction, the whole front end portions of the plurality of hinged tightening fin rods 341 are in a furled structure, and at this time, the outer side of the flexible connecting tube 43 is uniformly extruded by the front end portions of the plurality of hinged tightening fin rods 341.
When the omnidirectional tightening barrel 5 rotates counterclockwise, the front end portions of the hinged tightening fin rods 341 located inside the omnidirectional tightening barrel 5 are inclined in reverse order, and the front end portions of the plurality of hinged tightening fin rods 341 are in an unfolded structure as a whole, and are all away from the plurality of hinged tightening fin rods 341 outside the extruded flexible connecting tube 43.
In addition, when the flexible connecting tube 43 is not extruded, the plurality of internal hinged ridges 44 are in a linear structure, and at the moment, the telescopic gastroscope pipeline inside the flexible connecting tube 43 cannot be obstructed, because the front ends of the plurality of hinged tightening fin rods 341 rotate along with the inclination to extrude the outside of the flexible connecting tube 43, and the telescopic tube 42 can be driven to rotate synchronously when the omnibearing tightening tube 5 is rotated, so that after the flexible connecting tube 43 is extruded, the internal hinged ridges 44 inside the flexible connecting tube 43 can be deformed into a spiral structure, and the stability of the external side of the gastroscope tube band occluded by the spiral internal hinged ridges 44 is higher.
Step 300, loosening the channel flexible outer tube mechanism 4 by reversely rotating the omnibearing tightening barrel 5, so that the gastroscope pipeline can stretch out and draw back along the interior of the channel flexible outer tube mechanism 4 again.
Because the elastic abutting spring in the thrust conversion box 1 always props up the one-way toothed tube 31, and the one-way toothed tube 31, together with the positioning connecting tube 33 and the omnibearing tightening tube 5, moves towards the back of the thrust conversion box 1, the annular insection on the back of the omnibearing tightening tube 5 is always attached to the one-way insection ring 342 on the front surface of the linkage tightening disc 34, and therefore, the omnibearing tightening tube 5 can only rotate clockwise in a one-way mode in a conventional state, and the front end positions of the plurality of hinged tightening fin rods 341 are controlled to be closed.
When a plurality of articulated fin poles 341 that tighten up need to expand, need the all-round section of thick bamboo 5 of straining of manual pull-back, drive one-way tooth pipe 31 extrusion elasticity butt spring, all-round 5 whole forward movements of a section of thick bamboo of straining this moment are a small amount of distances for the annular insection at the all-round 5 back of straining breaks away from the one-way insection ring 342 of the positive quotation of linkage tightening plate 34, can all-round 5 of straining of counter-clockwise rotation this moment, thereby expand a plurality of articulated fin poles 341 that tighten up.
