1. The function of the eyepiece of an optical microscope It is to further enlarge the real image that has been magnified by the objective lens and has a clear resolution, to the extent that the human eye can easily distinguish it.

A surgeon uses a handheld device that uses ultrasonic energy. This is electricity converted into mechanical energy. It's used to cut tissue, seal blood vessels, and control bleeding.

Like many medical facilities across the nation, our supply chain is feeling the effects of Hurricane Helene’s aftermath. Johns Hopkins Medicine currently has a sufficient sterile fluid supply to meet treatment, surgical and emergency needs. However, we have put proactive conservation measures into place to ensure normal operations, always with patient safety as our first priority. Examples of sterile fluids include intravenous (IV), irrigation and dialysis fluids. Learn more.

2. The relationship between the eyepiece and objective lens of an optical microscope. The objective lens has already distinguished the fine structures clearly. If it is not magnified by the eyepiece, it cannot reach the size that the human eye can distinguish, and then it cannot be seen clearly; However, fine structures that cannot be distinguished by the objective lens cannot be seen clearly even after being magnified by a high-power eyepiece. Therefore, the eyepiece can only serve as a magnifying lens and will not improve the resolution of the microscope. Sometimes, although the objective lens can distinguish two objects that are very close together, the distance between the images of these two objects is smaller than the resolution distance of the eye, so it is still difficult to see clearly. So, the eyepiece and objective lens are both interrelated and mutually restrictive.

Eyepiece: Installed at the upper end of the lens barrel, usually with 2-3 pieces, engraved with symbols of 5 ×, 10 ×, or 15 × to indicate its magnification, usually equipped with a 10 × eyepiece Objective lens: Installed on the rotator at the lower end of the lens barrel, there are usually 3-4 objective lenses, among which the shortest one engraved with the "10 ×" symbol is the low magnification lens, the longer one engraved with the "40 ×" symbol is the high magnification lens, and the longest one engraved with the "100 ×" symbol is the oil lens. In addition, a circle of different colored lines is often added to distinguish between the high magnification lens and the oil lens

Surgeons may use traditional tools. These include surgical knives (scalpels). But both open and minimally invasive surgery can also use these other methods. Their use depends on what needs to be done.

The magnification of the eyepiece is inversely proportional to its length, while the magnification of the objective lens is directly proportional to its length.

The objective lens is equivalent to the lens of a projector, and objects are inverted and magnified into a real image through the objective lens; The eyepiece is equivalent to a regular magnifying glass, and the real image formed by the objective lens is then transformed into an upright and magnified virtual image through the eyepiece

A surgeon can also use electrical tools. These run on high-frequency electric currents that cut and control bleeding. One example of this is electrocoagulation. It helps control bleeding by clotting the blood. Another example is electrodesiccation. It's used to remove small growths by destroying the tissue with an electric current.

The difference between eyepiece and objective lens in optical microscope The eyepiece and objective of a microscope are both convex lenses, with the difference being that the focal length of the eyepiece is shorter,

A laser is a device that sends out a concentrated focused beam of light. It can repair damaged tissue or destroy certain cells. The surgeon can use it to cut through tissue without damaging nearby cells. Laser has been used in place of surgical cutting tools in various surgeries. These include eye surgery, gynecological procedures, and dental procedures. It can also be used in cosmetic surgery. This would be used to remove skin scars, tattoos, wrinkles, and also small tumors.
