All three cautery tips—thepoint, the knife, and the button—should be in thorough benzin chamber of the cautery should be replenished andthe cap screwed on, and the rubber tube and bulb tip is held in a gas flame until it becomes a dull red. Thebenzin vapor is forced through the cautery by squeezing therubber bulb. Care is taken not to fill the rubber air reservoir. Fig. 22.—Thermocautery.

If this is doneprematurely, the vapor cools the tip and the heating process hasto be repeated. Some cauteries are provided with an apparatusby which the preliminary heating is accomplished through anextra tube connecting the benzin chamber, a stopcock controllingthe flow of benzin. From three to five minutes should be allowedto get the cautery in running order. Once heated, the rubberbulb should only be pressed sufficientl
