Abstract

A surgical instrument holder has a head assembly and a drive spindle assembly. The head has a second coupling end with a coupling device and interface for receiving and holding a surgical instrument. The instrument is held by a releasable locking mechanism having a ring slideably biased against the coupling device by a spring, and a connection device retaining the spring in a fixed position during use. The spindle assembly has a drive spindle rotatably housed in a cylindrical tube. The connection device provides a quick-release connection between the head and drive spindle assemblies, such that unlocking the connection device enables quick disassembly of the connection for cleaning and component sterilization. A method of use of the instrument holder allows the surgical instrument to be installed through an incision in a least invasive orientation separate from the holder.

Claims23

Dependent claims

A surgical instrument holder comprising:

a) a head assembly having a shank with a first driveable end connectable to a drive spindle assembly so as to transmit torque therethrough, and second coupling end comprising a coupling device having an interface for engaging a surgical instrument tool;
and
b) a releasable coupling locking mechanism disposed about the shank, the locking mechanism having a coupling ring slideably disposed about the shank and normally biased against the coupling device by a spring biased against the coupling ring by a connection device, the connection device releasably held to the shank in a fixed position during use;
and
c) the coupling end including parking and locking features for respectively parking and locking the surgical tool in the interface, the parking feature comprising a catch formed in the coupling end which receives a feature of the coupling ring to permit the releasable coupling locking mechanism to lock in a park position.
