What is a Vaginal Speculum?

A vaginal speculum is a medical device that is used to help visualize the vagina and cervix during a gynecologic exam. It is also used to help obtain samples of tissue or fluid from the vagina or cervix for testing. Vaginal speculums come in many different sizes and shapes, but all have a handle and two blades that open and close like a pair of scissors. The most common type of vaginal speculum is the metal, screw type. When inserting the vaginal speculum, the examiner will first lubricate thedevice and then insert it into the vagina. The blades of the speculum are opened once it has been inserted far enough into the vagina so that they can be placed on either side of the cervix. The examiner then opens the blades slightly so that they can get a good view of the inside of the vagina and cervix. Samples of tissue or fluid can be collected by swabbing them with a cotton-tipped applicator or by using a small brush. Biopsies can also be taken with a small punch biopsy instrument.

Special Features of the Screw Type Vaginal Speculum

The screw type vaginal speculum has a number of special features that make it an ideal choice for many women. First, the screw type design means that the device can be inserted and removed without having to remove any clothing. This is a great advantage for women who are self-conscious about their bodies or who do not want to have to remove their clothes in public. Second, the screw type design also allows the user to adjust the angle of insertion, which can be helpful in providing a more comfortable experience. Finally, the screw type vaginal speculum is made from medical grade stainless steel, which makes it durable and easy to clean.

Why Choose Screw Type Vaginal Speculum?

If you are looking for a vaginal speculum, you may be wondering why you should choose a screw type over another type. There are several reasons why screw type vaginal speculums are a good choice:


1. They are easy to use. Screw type vaginal speculums have a handle that you can twist to open and close the blades. This makes them much easier to use than other types of vaginal speculums, which can be difficult to open and close.


2. They are less likely to cause discomfort. Because screw type vaginal speculums have a smooth opening and closing motion, they are less likely to cause discomfort than other types of vaginal speculums.


3. They provide a better view. Screw type vaginal speculums tend to provide a better view than other types of vaginal speculums because the blades can be opened wider. This allows you to get a better look at the inside of the vagina.


4. They are easy to clean. Screw type vaginal speculums are easy to clean because they have fewer parts than other types of vaginal speculums. This means that there is less chance of bacteria build-up, which can lead to infection.

Screw Type Variations

There are three main types of screw type vaginal speculum: the Wickham, Graves, and Deschamps. The Wickham speculum is the most commonly used type of screw type vaginal speculum. It is made up of two blades that are hinged at the top and bottom. The blades are opened and closed by turning a knob at the top of the handle. The Graves speculum is similar to the Wickham speculum, but it has only one blade. The blade is hinged at the top and bottom and is opened and closed by turning a knob at the top of the handle. The Deschamps speculum is made up of two blades that are hinged together in the middle. The blades are opened and closed by pushing or pulling on a rod that runs through the middle of the handle.

Today there is an increasing demand for advanced procedures and machines that have the capability to produce high-quality precision parts at low cost. This demand has led to the invention of new types of machines and other machines are upgraded to increase or improve their capabilities. The Swiss screw machines are a type of machining equipment that has been developed with the sole purpose of machining components with great precision and efficiency. Are you interested to know how these machines work? The following post will help you understand the detailed working of the Swiss screw machines. Screw Type A

How Do Swiss Screw Machines Work?

It is not that difficult to understand how these Swiss screw machines work. Here are some steps involved in the working of these machines.
  • Step 1: Holding the Workpiece
This is the first step in the working of these screw machines. The headstock in a conventional lathe is fixed. A chuck or collet is used to hold the workpiece in place. This chuck is extended into the enclosure of the machine as a cantilever. Alternatively, it can also be supported by the tailstock on the end.
  • Step 2: Passing of Bar Stock
The chucking collet provides a passage for the bar stock to pass through it. The bar stock passes in the headstock which clamps it.
  • Step 3: Locating the Bar
The bar passes through the guide bushing and then emerges into the tooling area. During the machining, the bar is then located radially by the tooling area.
  • Step 4: Movement of Headstock
The Swiss screw machine has a headstock that moves. This distinguishes these machines from other types. The headstock moves back and forth along with the bar. This movement is performed by the headstock in the Z direction.
  • Step 5: Provision of Feed for Cutting
The gang slides of the machine feature turning tools. These tools make contact with the bar. The distance between this contact and the guide bushing is minimal, i.e. within the range of 1 mm to 3 mm. The bar moves in such a way that feed is provided for cutting.

Where are Swiss Screw Type a Health Equipments Parts Used?

The parts machined using the Swiss screw machining technique are used in a variety of industries, including aerospace, electronics, defense, etc. The most common applications which use these parts are as follows:
  1. Fasteners used in medical applications
  2. Grommets and bobbins
  3. Miniature screws
  4. Contact pins for electronic components
  5. Collets for watch balance springs
So, this is how these machines work. Swiss screw machining is preferred by most industries due to the benefits offered by this technique. High precision can be obtained by implementing this method. We pride ourselves on offering quality work to our customers.  Norwood Screw Machine Parts is one of the most experienced and trusted Swiss screw machining parts manufacturers in the USA.
