A "SURE GRIP" TYPE OF RESECTOSCOPE SHEATH LOCK GEORGE 0. BAUMRUCKER
There is an increasing tendency among urologists to perform a more complete prostatic resection by endoscopic means. There is also a greater tendency to use counter pressure against the prostate rectally to obtain this end. As a result, there has been an increase in the use of the one-hand technique of holding the resectoscope, the other hand being used for rectal pressure. The friction grip between the sheath and the working element of all resectoscopes on the market was made to separate easily and ·was designed for the original Stern-McCarthy resectoscope, where no pull was made at this junction. Often after a year's use or less, there is a tendency for the prongs to separate and the sheath to disengage from the working element during resection.
Fro. 1
Mr. Frederick J. 'Wallace of American Cystoscope J\l[akers, Inc., has suggested that substitution of the bayonet lock, as now used on the cystoscope, would solve the problem. I believe this ·would be an excellent modification, but until this comes to pass, the following simple modification (fig. 1) will suffice. For the past 6 years I have had success in this respect by using a small rubber band between the water post of the sheath and its spring knob. This will hold the working element to the sheath rather than expel it, as is true with the present spring action. SUMMARY
This device holds the sheath against the ·working element firmly and allows for a one-handed technique. The sheath can be released from the working element simply twisting the knob forward.
