Abstract
The utility model discloses a three-purpose gun nozzle extension gun head for microscopic root canal treatment. The three-purpose muzzle extension gun head body consists of a pintle and a needle head which are integrally formed, and a bolt support structure is arranged at one end of an opening of the pintle; the outer wall of the pintle is attached with anti-skid particles; the inner wall of the pintle is attached with a rubber sleeve. The utility model discloses supporting three way rifle mouth uses and to go deep into root canal depths with the rifle head for the inside piece or the liquid of clearance root canal can operate under the microscope, does not influence the operator field of vision, has solved the technical defect that traditional three way rifle head can't go deep into the inside operation of root canal under the microscope, but high temperature disinfection reuse saves social resource and satisfies the market demand.
Description
Technical Field
The utility model relates to the field of medical equipment, especially, relate to a three way rifle mouth extension rifle head that can be used to micro root canal therapy.
Background
Endodontic surgery, also known as endodontic treatment, is an operation in dentistry to treat pulp necrosis and root infection. This procedure preserves the teeth and is thus complementary to an extraction procedure. The principle of root canal therapy is to remove infectious substances and necrotic tissues in a root canal to the greatest extent by mechanical and chemical methods, and prevent or promote healing of periapical lesions by filling the root canal and closing the crown and the apical tip.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a three way rifle mouth extension rifle head to prior art not enough. The utility model discloses simple structure, modern design, reuse.
The utility model aims at adopting the following technical scheme to realize: a three-purpose muzzle extension gun head for microscopic root canal therapy, the body is composed of a pintle and a needle head which are integrally formed, one end of the opening of the pintle is provided with a bolt support structure, and the bolt support is used for installing the three-purpose gun on the original muzzle, the three-purpose gun is convenient to bear force and simple to install; the anti-skid particles are attached to the outer wall of the pintle, so that the surface friction force of the pintle is increased, and the installation and the disassembly of the lance head are conveniently prolonged; the rubber sleeve is attached to the inner wall of the pintle, so that the friction force between the extension gun head and the three-purpose gun nozzle can be effectively increased, and the effective air tightness between the pintle and the three-purpose gun nozzle can be ensured; the inlet position of the rubber sleeve is in an inverted cone structure, so that the three-purpose gun nozzle can be conveniently and quickly inserted; the tail end of the needle head is provided with a nozzle.
As a supplement to the above technical scheme, the length of the needle head is 15mm, the inner diameter is 0.3mm, and the outer diameter is 0.6mm.
As a supplement to the above technical solution, the pintle has a length of 15mm, an inner diameter of 4mm, and a U-shaped cross-section.
As a supplement to the technical scheme, the thickness of the rubber sleeve is 0.6mm.
The utility model has the advantages that: the utility model discloses supporting three way rifle mouth uses and to go deep into root canal depths with the rifle head for the inside piece or the liquid of clearance root canal can operate under the microscope, does not influence the operator field of vision, has solved the technical defect that traditional three way rifle head can't go deep into the inside operation of root canal under the microscope, but high temperature disinfection reuse saves social resource and satisfies the market demand.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, a bolt support 1, a rubber sleeve 2, a pintle 3, anti-skid particles 4, a needle head 5 and a nozzle 6.
Detailed Description
The invention is further described with reference to the drawings and the detailed description.
As shown in figure 1, the three-purpose muzzle extension gun head for the micro root canal therapy of the utility model comprises a body which is composed of a pintle 3 and a needle head 5 which are integrated into a whole, one end of the opening of the pintle 3 is provided with a bolt support 1 structure, the bolt support 1 is used for installing the three-purpose muzzle on the original muzzle of the gun, the utility model is convenient to bear force and simple to install; the anti-skid particles 4 are attached to the outer wall of the pintle 3, so that the surface friction force of the pintle 3 is increased, and the gun head is convenient to assemble and disassemble; the rubber sleeve 2 is attached to the inner wall of the pintle 3, so that the friction force between the extension gun head and the three-purpose gun nozzle can be effectively increased, and the effective air tightness between the pintle 3 and the three-purpose gun nozzle can be ensured; the inlet of the rubber sleeve 2 is in an inverted cone structure, so that the gun nozzle of the three-purpose gun can be rapidly inserted conveniently; the end of the needle 5 is provided with a spout 6.
As shown in fig. 1, the working principle of the present invention is as follows: it is handheld the utility model discloses a on 3 outer walls of pintle of three way rifle mouth extension rifle head, convenient atress when bolt support 1 makes the installation, the installation is simple, 3 outer walls of pintle are with anti-skidding granule 4, increase the surperficial friction power of pintle 3, the installation and the dismantlement of convenient extension rifle head, insert three way rifle mouth in the pintle 3, 3 inner walls of pintle are with rubber sleeve 2, can effectively increase the frictional force of extension rifle head and three way rifle mouth, and guarantee effectual gas tightness between pintle 3 and the three way rifle mouth, and 2 import positions of rubber sleeve are the back taper structure, the three way rifle mouth of being convenient for insert fast, after the installation is accomplished, length is 15mm, the internal diameter is 0.3mm, the external diameter can be deep depths for 0.6 mm's syringe needle 5, can produce a large amount of dentine pieces among the clearance root canal preparation process, but high temperature disinfection reuse.
The foregoing embodiments have been described in some detail for the purposes of illustration, but are not to be construed as limiting the invention, and those skilled in the art will be able to make variations, modifications, substitutions and alterations herein without departing from the principles and spirit of the invention.
