Rotary instrument storage, monitoring, and access control system
A smart storage and access control system for rotary instruments such as dental burs is provided. The system includes a base with at least one collet configured to secure or release a rotary instrument. A user authenticator is included to verify user identity and authorization, as well as a controller operatively connected to the authenticator and collet. Upon verification, the controller signals the collet to release or retain a rotary instrument associated with a user. The system may include sensors for detecting instrument presence, visual indicators for status display, and a protective cover that disables release when open. A cam-driven collet mechanism converts motor rotation into linear movement for secure clamping. The controller may record access data in a tamper-resistant digital ledger and analyze usage patterns using artificial intelligence to predict maintenance needs. The disclosed system and methods improve accountability, security, and reliability for usage of precision rotary instruments.
1 . A system for storage of a rotary instrument comprising:
at least one rotary instrument, the at least one rotary instrument having a working end and a holding end;
a base comprising at least one collet, the at least one collet configured to secure or release the holding end of the at least one rotary instrument;
a user authenticator configured to verify a user authorization; and
a controller configured to signal the at least one collet to secure or release the at least one rotary instrument upon receiving verification from the user authenticator if a user is authorized for removal of the at least one rotary instrument.
2 . The system of claim 1 , wherein the user authenticator is selected from the group consisting of: a fingerprint reader, a radio-frequency identification (RFID) reader, a facial recognition sensor, a passcode entry device, and combinations thereof.
3 . The system of claim 1 , wherein the at least one rotary instrument comprises two or more rotary instruments, and the base comprises at least two respective collets for the two or more rotary instruments, and wherein the controller is configured to permit a user to remove only one rotary instrument at a time until a previously removed rotary instrument is returned to its respective collet.
4 . The system of claim 1 , further comprising at least one sensor configured to detect a presence or absence of the at least one rotary instrument within a corresponding collet.
5 . The system of claim 4 , wherein the controller is further configured to generate an alert if the at least one rotary instrument is absent or incorrectly inserted into the corresponding collet.
6 . The system of claim 1 , further comprising a visual indicator associated with the at least one collet, the visual indicator comprising a light-emitting diode (LED) that changes color to indicate one or more conditions of the at least one collet selected from the group consisting of: available, in use, worn, unauthorized, an error condition, and combinations thereof.
7 . The system of claim 1 , further comprising a transparent protective cover configured to restrict access to the at least one rotary instrument when the transparent protective cover is closed, and a sensor configured to detect whether the transparent protective cover is open or closed.
8 . The system of claim 1 , wherein the controller is configured to record user identification data and rotary instrument access events in a data log stored on a secure digital ledger.
9 . The system of claim 1 , further comprising an artificial-intelligence (AI) module configured to analyze rotary instrument usage patterns and predict maintenance or replacement needs.
10 . The system of claim 1 , wherein the at least one collet is actuated between a secure position and a release position by a cam-driven mechanism.
11 . The system of claim 10 , wherein the cam-driven mechanism comprises a spur gear having a cam profile on an upper surface, the cam profile configured to lift or lower a collet holder to respectively release or secure the at least one rotary instrument.
12 . The system of claim 11 , wherein the spur gear is driven by an electric motor.
13 . The system of claim 10 , wherein the collet comprises a slotted structure that radially compresses around the holding end of the at least one rotary instrument when driven axially into a collet holder.
14 . The system of claim 13 , wherein the collet is biased toward an open position by a spring and transitions to a closed position when the collet holder is linearly advanced by the cam-driven mechanism.
15 . The system of claim 10 , further comprising an anti-rotational guide configured to prevent rotation of a collet holder while permitting vertical translation.
16 . A method for secure storage and controlled access of a rotary instrument, the method comprising:
providing a system for storing at least one rotary instrument and at least one rotary instrument stored therein;
receiving, by a user authenticator, an authentication request from a user;
verifying, by the user authenticator, a user authorization;
transmitting, by the user authenticator, a verification signal to a controller; and
upon determining that the user is authorized, signaling, by the controller, at least one collet to release a holding end of the at least one rotary instrument.
17 . The method of claim 16 , further comprising recording user identification data, time of access, and rotary instrument status in a data log stored on a tamper-resistant ledger or blockchain database.
18 . The method of claim 16 , further comprising detecting presence or absence of a rotary instrument using at least one sensor associated with the at least one collet.
19 . The method of claim 16 , further comprising analyzing recorded usage data with an artificial-intelligence module to predict rotary instrument wear or maintenance requirements.
20 . The method of claim 16 , further comprising illuminating an LED indicator associated with the at least one collet to indicate rotary instrument status during retrieval or return, and restricting access such that only one rotary instrument is released at a time until a previously released rotary instrument is returned.
