Is the injection between Bucks and Dartos (seems most likely) or Tunica and Bucks or is it different by provider? There are a lot of arterial and vascular branches between Bucks and the Tunica. Shoving cannulas around seems risky.
Which locations are generally injected? The area I worry about most is the dorsal side. That anatomical diagram is not totally correct, as dorsal arteries can go quite lateral. Some people have funny anatomical variants.
Cannulas by design are meant to provide the additional advantage of being less pointy or abrasive when injected and have been demonstrably safe when handled by experienced practitioners. Believe it or not, even traditional needles can be relatively safe if handled by those who are very skilled in terms of dexterity & highly knowledgeable of the procedure(s). Both observations have come from the fact that many of the leading phallo-clinics have utilized both instruments in high enough volume (i.e. sample size) that would lead me to confidently put forward these assertions.
I suppose in theory a blunt-tip cannula would be relatively safer than a needle, and if it truly concerned you that much, you could request for a blunt-cannula if your performing physician normally uses needles (assuming of course, they are willing to grant this request).
Damage to to arterial, vascular, sensory/nervous, and/or tissue-related parts of your penile anatomy are exceedingly rare when reviewing feedback from both patients & physicians of the last 15 years or so, in fact possibly non-existent (i.e. patient reporting) when the injector is qualified, skilled, and experienced.
