Cannula with recessed hub structure

Abstract

A portable and passive safety intraosseous device to allow for direct introduction of medications, etc., within the intermedullary space of a subject patient's bone or, if needed, the removal of certain substances from such a subject patient's bone. Such a device permits direct drilling and placement of a cannula within the subject bone with access external to the subject patient's skin, permitting, as well, connection of a tube for such introduction / removal purposes. The ability to provide a passive safety unit allows for facilitated utilization in, for instance, emergency situations with the entire device provided for utilization thereof. The device includes a drilling component with a permanently attached stylet and a removable cannula, a power supply for a single drilling operation, a mechanism to draw the stylet back into the drill component after use and disengagement from the cannula, and an automatic closure that activates with the separation of the cannula.

AI Technical Summary

Benefits of technology

The invention is a versatile apparatus for drilling bones that has several technical advantages. It includes a drill with a stylet / cannula implement that is safe to use and can be easily disposed of. The drill has a single portable structure that can be easily operated and disposed of. The stylet can be retracted back into the drill for easy disposal. The device can be used with a sensor to measure pressure during bone entry. The device can be provided with an internal movable combination of a stylet and cannula that allows for simultaneous attachment and detachment. The device can be easily transported and disposed of. The device can be provided with a protective cap to prevent closure and a light to aid in visibility. The device can be used with a sensor to measure pressure during bone entry. The sensor can also activate the retraction mechanism and detach from the cannula. The overall device is designed to provide safety and ease of use during bone drilling procedures.

Problems solved by technology

Such a distance has been known to be rather susceptible to contact with surfaces and objects through patient movement, at least.

As a result, there has been a rather important, yet unmet, need within the industry to supply a suitable structure to accommodate such needed modifications.
