Fig. 5—Tumor forceps of a serviceable pattern for fistula 
operation. The style of the jaws in tumor forceps is a mat- 
ter that should be carefully noted in purchasing such an in- 
strument. For instance, some vulsellum forceps are so de- 
signed that the incomplete curve of the jaws together with 
their slender and weak construction makes them too delicate 
for much veterinary surgical work. The instrument illus- 
trated above is designed so that with them a firm grasp of 
tissues is possible and a secure hold is insured. 
Fic. 6.—DRrAINAGE TUBE AND INSERTER. 
By means of the drainage tube inserter it is possible to in- 
troduce a rubber drainage tube with a minimum of invasion 
of sound tissue. This, in many cases, is an important fac- 
tor, as it prevents needless contamination of uninvaded parts, 
limits the area of infected tissue and possible resultant com- 
plications and greatly facilitates the execution of this part of 
the technic. Hemorrhage is reduced to a minimum, opera- 
tions are completed with dispatch and, therefore, with less 
danger of stirgical shock when these appliances are employed.
