Description
Technical field
The utility model relates to oral surgery the field of medical instrument technology, more particularly to one kind is for pulling out lower jaw impacted tooth
The device of embryo.
Background technique
With the development of the society, the adjustment of people's dietary structure, the disease incidence of lower jaw impaction is continuously increased, especially third
The position ground one's teeth in sleep is special, in close relations with adjacent teeth, causes operating difficulty larger.Third molar impaction usually causes pericoronitis,
Two saprodontias ground one's teeth in sleep and the symptoms such as loosening, the inflammatory absorption of alveolar bone, remporomandibular joint snap, pain of dehiscing, need to pull out more.Mouthful
It is to bone that chamber Clinical Surgery, which pulls out the step of complete mandibular denture tooth bud most critical, pulls out the common chisel bone Traditional chisel of impacted tooth
Bone, split tooth, advantage be it is time-consuming short, veteran patient can be to complete extraction of boning, but the disadvantage is that when hammering in the short time
Vibration is big, the fracture of postoperative more concurrent swelling, pain, bleeding and the damage of mandibular nerve and mandibular.With technological progress,
Boning, there are also high speed turbine mobile phones and piezosurgery osteotomy for instrument: high speed turbine mobile phone is to be carried out using air turbine high-speed rotation to tooth body
The medical instrument grind, bore, cutting, cutting etc., its working principle is that turbine high speed rotation is driven using high-speed gas, to drive rotor
Clamped vehicle needle high speed rotation, but high-speed turbine drill bones and divides tooth, takes a long time, and the visual field is poor, and head is put into mouth easily
Shield portions sight, water spray also make blurred vision, and misoperation drill point Yi Juanzhu surrounding soft tissue cause damage and gas into
Enter surrounding tissue and cause wind-puff etc., in addition there are also the defects of expensive, maintenance is at high cost for high speed turbine mobile phone；Ultrasonic bone
Knife is to control the Oscillation Amplitude of cutter head by adjusting supersonic frequency to have the function that cutting, carry out lower tooth using piezosurgery osteotomy
The close impacted tooth of slot nerve channel neighbouring relationship pulls out operation, has and can protect soft tissue, effectively prevention neurotrosis, precision
The advantages such as sensitivity height, but the disadvantage is that operation is at high price, operating time is long, and the operation of time-consuming huge length is brought psychologically to patient
Pain physiologically.Currently, clinically not dedicated for pulling out the device of lower jaw impaction tooth bud.
Therefore, it is urgent to provide a kind of for pulling out the device of lower jaw impaction tooth bud, to solve the above problems.
Utility model content
The purpose of the utility model is to provide a kind of for pulling out the device of lower jaw impaction tooth bud, is for the first time used for it
Lower jaw impaction tooth bud is pulled out, operating time can be greatly shortened, improves procedure efficiency；The peripheral surface of its interconnecting piece is equipped with
Along the radial direction limiting section outstanding outwardly of the interconnecting piece, prevents from excessively cutting lower jaw impaction tooth bud and injure lower alveolus mind
Through and damage adjacent teeth.
To achieve the goals above, the utility model takes following technical scheme.
It is a kind of for pulling out the device of lower jaw impaction tooth bud, described device includes cylinder, interconnecting piece and bar portion, the connection
The both ends in portion are respectively connected to the cylinder and the bar portion, wherein the cylinder is hollow structure, described cylinder one end end face
Equipped with sawtooth, run through the other end of the cylinder along aperture, the aperture is axially arranged in the cylinder lateral wall；In the connection
Limiting section is set in the peripheral surface in portion, and the limiting section protrudes outwardly along the radial direction of the interconnecting piece.
Further, the cylinder, the interconnecting piece and the bar portion are an integral structure.
Further, graduation mark is equipped on the outside of the cylinder.
Further, the cylinder is cylinder, and internal diameter range is 6~12mm.
Further, the bar portion is equipped with a bayonet in one end far from the interconnecting piece, and the bayonet is for being clamped dentistry
Plant contra-angle handpiece.
Further, the limiting section is in the non-aperture side wall same lateral position of the cylinder.
A kind of good effect for pulling out the device of lower jaw impaction tooth bud of the utility model is:
(1) it is used to pull out lower jaw impaction tooth bud, the time of operation can be greatly shortened, improve efficiency.
(2) design of limiting section can prevent from excessively cutting lower jaw impaction tooth bud, to avoid nervus alverlaris and damage is injured
Hurt adjacent teeth.
(3) easy to operate, do not easily cause bone to burn, necrosis, it is more minimally invasive.
