MULTI-FUNCTION DERMATOLOGICAL BIOPSY PEN

摘要

A method for effecting a dermatological biopsy procedure and a hand-held instrument for use in such procedure. The instrument has a pen-like housing with an aperture and a biopsy site marker. A syringe for dispensing an anesthetic to a selected marked biopsy site on a patient's skin and a biopsy-sampling blade such as a skin punch or scraper and a wound closure device for closing the biopsy wound with a suture, adhesive or cauterant are contained within the housing. The aperture of the instrument is placed directly against the marked biopsy site and the syringe, biopsy blade and wound closure device are controlled to alternately extend and retract through the aperture and operatively effect anesthetic dispensing, biopsy sampling and wound closure.

主权项

1. An instrument for use in a dermatological biopsy sampling procedure comprising a hand-held device comprising:
c) a member configured for effectively dispensing an anesthetic to a selected biopsy site on a patient's skin, and d) a member configured for taking a biopsy sample from the biopsy site, wherein the instrument comprises a housing for the anesthetic dispensing member and biopsy sample taking member, the housing having an aperture therein adapted to be placed into contact directly against the biopsy site and wherein the instrument comprises an extension and retraction mechanism configured to enable the anesthetic dispensing member and biopsy sample taking member to be alternately brought into proximate position relative to the selected biopsy site through the aperture, to alternately and sequentially provide an anesthetic to the selected biopsy site and to take a biopsy sample from the anesthesized biopsy site, respectively, without necessity for removal of the instrument from contact with the biopsy site.
