Description
Technical field
The present invention relates to medical instruments fields, and in particular to a kind of opener.
Background technology
During Medical treatment, be frequently encountered some especial patients, morbidity when can critical mandibular joint, when need open
When mouth is treated, the upper and lower tooth for prying open patient is needed.And this process is usually completed with opener.Opener is also known as dehisced
Device is for having difficulty in breathing or the clouded in mind instrument for strutting oral cavity needed whens gastric lavage etc..Usual opener ontology is in " U "
Shape,
Traditional opener is usually " U " shape, and two ends of opener ontology are connected with a handle respectively.It is using
In the process, " U " shape opener is typically placed in the oral cavity of patient's mouth rear distraction patient, using the opener of this structure,
It is simple in structure, easy to operate and of low cost, but in operation, due to usually unhygienic in oral cavity, to avoid oral cavity
Pollution steals to taste will spray oral-cavity disinfectant in oral cavity, currently, what the sprinkling of oral-cavity disinfectant was usually performed manually by, there is behaviour
Make inconvenient problem.
Invention content
The invention is intended to provide a kind of opener, spread by hand oral-cavity disinfectant is needed to solve traditional opener, operation is not
Just the problem of.
In order to achieve the above objectives, technical scheme is as follows：A kind of opener, including propulsive mechanism, propulsive mechanism
Including fixed plate, lead screw is rotatably connected in fixed plate, lead screw is equipped with threaded portion, nut is threaded on threaded portion, Gu
First support bar and second support bar are fixedly connected on fixed board, first support bar is inclined centered on lead screw with second support bar
Tiltedly it is arranged, the first sliding block is slidably connected in first support bar, second support bar is equipped with the second sliding block, the first sliding block, nut
And second be equipped with through-hole on sliding block；Lead screw outer cover, which is equipped with, promotes case, promotes and is equipped with fixed link in case, and one end of fixed link is solid
Surely it is connected on the inner wall for promoting case, the other end of fixed link is each passed through the logical of first sliding block, nut and the second sliding block
Hole is simultaneously fixedly connected on opposite inner wall；It promotes in case and slidably connects isolation board, first is fixedly connected on isolation board and is stretched
Contracting plate and the second expansion plate, the first expansion plate and the second expansion plate form the first containing liquid chamber and second with the inner wall of case is promoted respectively
It is equipped with liquid outlet on containing liquid chamber, the first containing liquid chamber and the second containing liquid chamber；Further include having supporting mechanism, supporting mechanism includes the upper jaw
Plate and mandibular plate with maxillary plate rotation connection, are equipped with multiple disinfection mouths, maxillary plate and lower jaw on maxillary plate and mandibular plate
It is equipped with sliding slot on plate, case is promoted to be slidably connected in sliding slot, reservoir is equipped on maxillary plate and mandibular plate, is consolidated in reservoir
Surely be connected with partition board, slidably connect sliding tube in reservoir, sliding tube is equipped with filtering port, sliding tube respectively with the first liquid storage
Storehouse and the second containing liquid chamber are connected.
Using above-mentioned technical proposal, when practical application, propulsive mechanism, which plays, promotes maxillary plate and mandibular plate, it is made to open
Effect, operating personnel's rotary screw rod, due to being threaded with nut on the threaded portion of lead screw, lead screw rotation drives nut rotation,
It is moved along lead screw while nut rotation, nut moves along lead screw and drives the first sliding block and the second sliding block edge respectively by fixed link
First support bar is slided with second support bar, and isolation board movement, isolation board are pushed in the first sliding block and the second sliding block sliding process
Movement can squeeze the first expansion plate and the second expansion plate, and the first expansion plate and the second expansion plate are squeezed after-contraction so that the
The area of one containing liquid chamber and the second containing liquid chamber reduces, and the first containing liquid chamber and the second containing liquid chamber play the role of storing thimerosal, when
After its area reduces, thimerosal can outflow, and since the first containing liquid chamber is connected with sliding tube, thimerosal flow to sliding tube along liquid outlet
It is interior, and flow in reservoir by filtering port.
Fixed link movement simultaneously drives the propulsion case movement of connection fixed thereto, due to promoting case to be slidably connected at sliding slot
It is interior, promote case that can be moved along sliding slot, maxillary plate and mandibular plate play the role of fixed patients teeth position, and case is promoted to be moved along sliding slot
During dynamic maxillary plate can relatively rotate with mandibular plate, increase the opening angle between maxillary plate and mandibular plate, play opening
The effect of patient's mouth, meanwhile, it promotes case to be slided along sliding slot and sliding tube is driven to be slided along reservoir, sliding tube is slided along reservoir
The area of reservoir can be reduced in the process so that the thimerosal in reservoir, which is flow to by disinfection mouth in patient's mouth, to carry out disinfection.
The advantageous effect of the technical program is：
Nut is driven to move 1. the present apparatus is rotated by lead screw, nut movement drives connection fixed thereto by fixed link
Case movement is promoted, achievees the purpose that adjust maxillary plate and mandibular plate opening angle, by adjusting the advance distance of case, adjustment is promoted
Opening angle between maxillary plate and mandibular plate, it is easy to operate.
It drives nut to move 2. the present apparatus is rotated by lead screw, and then the first sliding block and the second sliding block is driven by fixed link
Movement, the first sliding block and the second slide block movement can squeeze the area of the first containing liquid chamber and the second containing liquid chamber by isolation board, in turn
Thimerosal in first containing liquid chamber and the second containing liquid chamber is expressed to by sliding tube in reservoir, on the other hand, the present apparatus is logical
The mobile drive sliding tube movement for promoting case is crossed, sliding tube moves the area that can squeeze reservoir so that the disinfection in reservoir
Liquid is flow in patient's mouth automatically by disinfection mouth, easy to operate.
Preferably, as an improvement, multiple indentation slots are equipped on maxillary plate and mandibular plate.The setting of indentation slot is convenient
The tooth of patient is fixed, and then the preferably position of fixed maxillary plate and mandibular plate, avoid maxillary plate and mandibular plate from
It falls off in patient's mouth.
Preferably, as an improvement, one end of lead screw passes through fixed plate and is fixedly connected with rotating disk.It is revolved by rotating
Driven by rotary disc lead screw rotates, and rotating disk is related to facilitating doctor to replace the rotation direction of lead screw at any time, before realizing and promote case
Into and retreat, and then reach adjustment maxillary plate and mandibular plate between opening angle, it is easy to operate.
Preferably, as an improvement, rotating disk outer wall is equipped with anti-skid chequer.Anti-skid chequer can increase rubbing for rotating disk outer wall
It wipes, avoids having skidded phenomenon when rotation rotating disk.
Preferably, as an improvement, maxillary plate is made with mandibular plate of elastic material.Elastic material is compared to metal
Material can provide higher comfort level to patient, while elastic material can avoid maxillary plate, mandibular plate and patients teeth and generate just
Property contact, play the role of protect patients teeth.
Preferably, as an improvement, case is promoted to be equipped with headlamp close to one end of maxillary plate.Promote the headlamp on case
Doctor can be facilitated to observe the intraoral state of patient, it is easy to operate.
