Abstract
A uniportal surgical device having a slotted clear cannula, a blade and a housing, wherein the cannula is attached to the housing, and wherein the blade is enclosed in the housing and is slidable into the cannula is disclosed. The device further has a device for locking a viewing device in place relative to other components of the device. A method for a performing an operative procedure on a target tissue in a subject using the uniportal surgical device is also described.
Core Innovation
The invention provides a surgical device that includes a housing and a slotted clear cannula attached to a distal end of the housing. The slotted clear cannula includes a cannula body with a proximal end and a distal end, and a longitudinal slot extending from the proximal end to the proximity of the distal end. A tube assembly having a proximate end and a distal end allows for inserting a viewing device.
The surgical device further includes a blade assembly comprising a blade, where the blade assembly is attachable to the distal end of the tube assembly. The device also includes a latch assembly with a scope lock assembly for holding the viewing device in a stationary position relative to the tube assembly. The scope lock assembly is a two-button pinch-type assembly, where compressing the buttons releases the viewing device and allows movement of the viewing device through the tube assembly.
The latch assembly is configured so that the proximate end of the tube assembly attaches to the latch assembly, and the distal end of the tube assembly slides through the housing and is capable of entering the slotted clear cannula from the proximal end of the clear cannula. The background problem described is the need for a compact uniportal endoscopic/arthroscopic surgical device that reduces conventional instrument and incision steps and avoids removing the endoscope to insert a blade.
Claims Coverage
This patent family has one independent claim. The independent claim covers a compact surgical device combining a slotted clear cannula, a blade assembly deployable via a tube assembly, and a two-button pinch-type latch/scope lock that holds a viewing device stationary relative to the tube assembly until compressed.
Slotted clear cannula attached to housing with longitudinal slot
A housing and a slotted clear cannula attached to the distal end of the housing, the slotted clear cannula comprising a cannula body having a proximal end and a distal end, and a longitudinal slot extending from the proximal end of the cannula to the proximity of the distal end of the cannula.
Tube assembly insertable viewing device with distal sliding through housing
A tube assembly having a proximate end and a distal end, wherein the tube assembly allows for inserting a viewing device, and wherein the proximate end of the tube assembly attaches to the latch assembly and the distal end of the tube assembly slides through the housing and is capable of entering the slotted clear cannula from the proximal end of the clear cannula.
Blade assembly attachable to distal end of tube assembly
A blade assembly comprising a blade, wherein the blade assembly is attachable to the distal end of the tube assembly.
Two-button pinch-type scope lock holding viewing device stationary
A latch assembly having a proximal end and a distal end, wherein the latch assembly comprises a scope lock assembly for holding the viewing device in a stationary position relative to the tube assembly, wherein the scope lock assembly is a two-button pinch-type assembly, wherein compressing the buttons releases the viewing device and allows movement of the viewing device through the tube assembly.
The independent claim centers on a compact uniportal surgical device architecture that aligns a viewing device with a slotted clear cannula using a tube assembly, while deploying a blade assembly via the same tube assembly. A two-button pinch-type scope lock assembly holds the viewing device stationary relative to the tube assembly and releases it when compressed.
Stated Advantages
Fewer instruments and incision steps compared with conventional methods.
Eliminates cannula obturator.
Avoids removing the endoscope to insert a blade.
Documented Applications
Example application: plantar fascia release / plantar fasciotomy using the device in a uniportal context.
Example application: lateral patellar release / patella realignment using an arthroscopic approach with the device.
