IMPROVEMENTS IN AND RELATING TO SURGICAL INSTRUMENTS, SYSTEMS AND METHODS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240016625 titled 'IMPROVEMENTS IN AND RELATING TO SURGICAL INSTRUMENTS, SYSTEMS AND METHODS

Simplified Explanation

The abstract describes a surgical instrument and system designed for the removal of a polyethylene acetabular liner from an implanted shell, minimizing the risk of damage to the shell.

  • The instrument consists of a stem with a proximal end and a distal end, a handle portion provided towards the proximal end of the stem, and a guide element provided towards the distal end of the stem.
  • The guide element includes a body element that defines a guide channel with a longitudinal axis, open at both ends along the axis, and one or more positioning elements.
  • The instrument is specifically designed for the removal of a polyethylene acetabular liner from an implanted shell, allowing for its replacement without damaging the shell.

Potential applications of this technology:

  • Orthopedic surgery: The instrument can be used in hip replacement surgeries to remove and replace polyethylene acetabular liners without damaging the implanted shell.
  • Medical device manufacturing: The system can be utilized in the production of hip replacement implants, ensuring the ease and safety of liner removal and replacement.

Problems solved by this technology:

  • Minimizing damage to the implanted shell: The instrument and system provide a solution to the challenge of removing and replacing polyethylene acetabular liners without causing harm to the shell holding it.

Benefits of this technology:

  • Improved surgical procedures: The instrument allows for the efficient and safe removal of polyethylene acetabular liners, reducing the risk of complications during hip replacement surgeries.
  • Extended lifespan of implants: By enabling the replacement of polyethylene acetabular liners, the technology can contribute to the longevity and functionality of hip replacement implants.


Original Abstract Submitted

a surgical instrument () and system incorporating such instruments, the instrument comprising: a stem (), the stem having a proximal end () and having a distal end (); a handle portion (), the handle portion being provided towards the proximal end of the stem; and a guide element (), the guide element being provided towards the distal end of the stem, wherein the guide element provides: a body element () defining a guide channel (), the guide channel having a longitudinal axis (x-x) and being open at both ends along the longitudinal axis; and one or more positioning elements (). the instrument and system are suited to the removal of a polyethylene acetabular liner () from an implanted shell (), for instance to remove that liner and replace it with another, whilst minimising the risk of damage to the shell holding it.
