拔牙钳的数种分类

Share:

拔牙钳顾名思义就是用来进行拔牙的器械,它是拔牙器械中对牙槽骨的损伤最小的,是在拔牙术中通常都会用到拔牙钳。

钳柄、关节及钳喙是拔牙钳三个主要组成部分。钳喙是主要工作端,是牙钳夹持牙体的部分。操作者握住的部分叫做钳柄,有四种形状:直角型、直线型、刺枪形和反角形,不同形状的拔牙钳各有不同的用法。

大多数拔牙钳钳喙都是对称型的,不对称的只有上颌磨牙钳因牙根分叉位置不同而采用不对称设计。

一套牙钳最少应由9把牙钳组成,分别是:下颌前磨牙钳、上颌前牙钳、上颌前磨牙钳、左上颌磨牙钳、上颌根尖钳、右上颌磨牙钳、下颌前牙钳、下颌磨牙钳、下颌根尖钳。

 

一、上颌前牙钳又根据口内解剖部分分类为:

1、上颌牙钳2、下颌牙钳3、左右拔牙钳

 

二、根据拔牙钳用途分类:

1、下颌前牙钳2、上颌第三磨牙钳3、上颌前牙钳4、下颌第三磨牙钳5、下颌双尖牙钳 6、牛角钳7、上颌根尖8、上颌磨牙钳9、下颌磨牙钳10、上颌双尖牙钳

从拔牙钳分类的名字,我们就可以知道它们究竟是作用于牙齿哪部分的手术。

大人和小孩的拔牙钳大小也不相同,小孩子因为会动,所以用的拔牙钳会比较大,不会因为孩子的乱动而锁定不了目标牙齿,大人的拔牙钳相对就会小,因为大人不会乱动,很容易就能钳住目标。

拔牙钳使用的注意事项:

1、用力适当,摇动、扭动和牵引相结合。

2、 根据牙齿的形态,尽量选择能够牢固夹持的牙钳。

3、牙钳应正确安置于牙颈部,勿伤及邻。

4、根据拔除牙位的不同,正确选用牙。

拔牙钳的正确握持方法:主要以右手使用,右手的大拇指放在牙钳关节处,虎口部贴紧钳柄,要使拔牙钳能开闭自如,食指及中指握紧对侧钳柄外侧而环指及小指置于其内。在夹牢牙体后,将环指及小指置于对侧钳柄外侧协助示、中二指形成合力握紧牙钳。

If you are working in any industrial plant or you are planning to set-up an industrial plant, you will also need an industrial flow meter. The industrial flow meters are very important for any industry as they are helpful in measuring the flow. There are different types of flow meter available in the market according to their uses and applications. Like digital rotameter flow meter, electromagnetic flow meter, chemical flow meter and many other. These flow meters are helpful in measuring the mass or volumetric flow rate. One can check the flow rate of liquids, gases, and different types of fluids using these flow meters. At present, there are many flow meter manufacturers available in the market who are manufacturing different types of rotameter transmitter, magnetic flow meter, and many others.

If you are also planning to get a flow meter for your industry, then, first of all, you should know about the different types of flow meters. Here we have shared the details about different types of flow meters based on different parameters.

Mass Flow Meters

As you can see in the name itself, that these are mass flow meters, which means they will be helpful in measuring the mass flow per unit of time. In the industries where the processes include the mass and not the volume, these types of flow meters are used. Some of the industries where these mass flow meters are used are power industry, pharma industry, mining industry, and many such other industries. Mostly people prefer to buy Coriolis mass meters.

Velocity Flow Meters

We have just read above about the mass flow meters which were basically used for mass flow rate measuring. The velocity flow meter is for calculating the volumetric flow rate. You will find different types of velocity flow meters like the electromagnetic flow meters, ultrasonic flow meters, and many such other flow meters.

Open Channel Flow Meters

The open channel flow meters are usually big, and dam shaped. They are mostly used in calculating the flow rate of flowing liquids. And that is why they are generally used for rivers, streams, sewer, irrigation channels, and other flowing liquids. One can take or calculate the reading of the flow rate with the help of these open channel flow meters.

Final words

These are some of the common flow meters which we have mentioned above, that can be used for different purposes. Other than these flow meters, there are few more like Differential Pressure Flow Meters, Positive Displacement Flow Meters, and many others. These flow meters vary in shapes and sizes, and the kind of materials they are used to measure. If you want to buy a flow meter for your industry, we recommend you check that for what purpose you need it. So that you do not end up buying the wrong flow meter. You can also ask other people who are of the same industry, to help you in selecting the right flow meter.

WHAT ARE SOLAR PANELS?

A solar panel is a device which is used for converting the heat energy into electricity. This device is used to convert the heat energy which we get from the sun in the form of ultraviolet rays. This is done by fixing the silicon chips over the solar device. The energy which we get after converting the heat energy is known as solar energy. Solar panels are nothing but a simple rectangular plate which is fixed on a pole. It is not mandatory to fix it on a pole, but generally, solar panels are used in this way. These silicon chips are generally known as solar cells. These cells produce more electricity when more light or ultraviolet rays fall on them. Solar cells are not much being used because silicon chips, which are used in it for producing electricity are very costly. However, many people have started using solar panels as it is more environment-friendly as compared to other electricity resources. For more information click here https://www.best-solar-panels.com/

WHAT IS SOLAR CHARGE CONTROLLER?

A solar charge controller is a device which is used for managing the power inside the battery of the solar panels. In the mechanism of the solar panels, a battery is present there which is used for storing the energy or power during the day when ultraviolet rays fall on the panels. The solar charge controller is responsible for keeping the power or energy balanced inside the battery. Here, balanced means not overcharged. If the battery of the panels gets overcharged during the day, then the battery will be drained in the night and the solar panels won’t be able to perform the task for which they are designed. That’s why a solar charge controller checks that the battery doesn’t get overcharged. There are other tasks too which a solar charge controller performs, but checking the power is its main task.

Generally, there are two types of a solar charge controller or we can say there are two technologies in which a solar charge controller works. They are as follows–>

1) PWM solar charge controller
2) MPPT solar charge controller
It has been said that the MPPT solar charge controller is more costly as compared to the PWM solar charge controller.

WHAT IS PWM SOLAR CHARGE CONTROLLER?

The PWM solar charge controller is an acronym for pulse width modulation. In PWM solar charge controller a direct connection is established between the solar panels and the battery. When the battery charge continuously at that time the voltage of the solar panels is made the same as of the battery. After the charging of the battery, the voltage of the battery is elevated, which in turn elevates the voltage of the solar panels. The voltage of both, solar panel and battery cannot be at the same level initially. If we do so, then the battery won’t be charged.

ADVANTAGES OF PWM SOLAR CHARGE CONTROLLER

Here are some advantages of the PWM charge controller–>
1) PWM solar charge controllers are less costly as compared to the MPPT solar charge controller.
2) These solar charge controllers are more durable.
3) These charge controllers are available in different sizes.
4) PWM solar charge controllers are being used in the solar systems for a long time and hence are reliable.

WHAT IS AN INVERTER?

An inverter is a device which is used for changing the frequency of direct current (DC) into the frequency of alternating current (AC). Alternating currents are more preferred than the direct currents in home appliances. But in most electronic devices, direct current is used. There was a need for conversion of alternating current to direct current and direct current to alternating current. That’s why an inverter was introduced in the market. But an inverter converts only direct current to alternating current. An inverter is also known as a power inverter. These two terms are used interchangeably. On the other hand, the device which is used for converting an alternating current into the direct current is known as a rectifier.

ADVANTAGES OF A POWER INVERTER

Here are some advantages of the power inverter–>
1) Power inverters are efficient.
2) Power inverter assures safety.
3) The physical properties of the power converter are very good. It has a very high capacity for load bearing.
