Abstract

A combined surgical laser fibre cleaver and stripper for use with all sizes of surgical laser fibre. The hinged device contains a cleaving blade 5 fixed on the lower part of the lid 3, a multi holed stripping blade 4 split between the upper part of the lid 2 and the base 1, and a compartment 6 to collect glass and plastic fragments. Grooves 8 in the base 1 and lid 2 of the device may securely clamp the laser fibre in position for cleaving and stripping. The lower lid part 3 holding the cleaving blade 5 may have an overhang 7 which acts as a finger guard. The blades 4, 5 may be removable and replaceable. The split lid 2, 3 enables the stripping blade 4 to make transverse cuts through the cable cladding to enable its removal, without cutting the glass core of the fibre using the blade 5.

Description

II
A combined surgical laser fibre deaver and stripper
Background
This invention relates to a device that will cleave and strip a laser fIbre optic cable used during laser surgical procedures. The fibre optic cables are referred to as surgical laser fibres and are made of a glass core covered with a plastic material such as nylon or Teflon, referred to as a cladding, in a manner similar to electrical wires. Several different diameter laser fibres are used depending on the type of surgery and type of laser being used.
When lasers are used to perform surgical operations they generally need a fibre optic cable to deliver the laser energy to the site of operation. During surgery tissue often sticks to the tip of the laser fibre which then burns and chars the tip of the fibre. A burnt or charred tip prevents the laser energy reaching the tissue and thus reduces the efficiency of surgery. To continue surgery the laser fibre must be deaved and stripped to remove the tissue and return the laser fibre to its original condition.
The current method of deaving and stripping surgical laser fibres requires the use of a tungsten blade mounted on a steel rod very much like a pen, or a pair of ceramic scissors and a pair of plastic pliers wire strippers. The problem is that two items are required to deave and strip the laser fibre.
Moreover, the stripper pliers have either a fixed diameter and a different pair is required for each diameter of laser fibre. There is a style of adjustable fibre stripper but the adjustment is often difficult to perform especially as safety glasses with coloured fitter lenses have to be worn and can restrict vision.
Statement of Invention
A combined surgical laser fibre deaver and stripper for use with all sizes of surgical laser fibres, containing a fixed cleaving blade, a split linear multi holed stripping blade and compartment to collect contaminated glass and plastic fragments.
Advantaaes The invention deaves and strips the laser fibre using just one device.
A measured length of cladding can be stripped without the need to change position of the laser fibre.
The cut off portion of the laser fibre and cladding, together with any contaminated tissue, Is collected in the recessed compartment. The glass portion can then safely be disposed of.
The divided lid enables a laser fibre to be stripped separately if required.
Introductioato drawinas The invention Is shown in the following drawings, Figure 1 shows the complete Invention and Figure 2 is an exposed drawing of the stripping blades that are set into the base and lid of the invention.
Detailectdescriotlon The Invention Is a metal box that contains cleaving and stripping blades set Into the lid and base. The metal box Figure 1 Is a box with grooves 8 and a compartment 6 cut Into the base 1 and grooves 8 cut into the first part 2 of the two part hinged lid 2 and 3.
Each groove 8 is a different size and Is machined to accept the appropriate diameter laser fibre. The laser fibre must be placed into the appropriate groove 8 such that the tip of the fibre to be cleaved overhangs the compartment 6. When the grooved part of lid 2 is dosed on to the laser fibre It is securely held in position for deaving and stripping.
The stripping blades 4 are inset Into the grooves 8o1 the base 1 and the grooves 8 of lid 2. The stilpping blades 4 are adjacent to each other so that when the lid 2 is dosed the blades 4 press into the plastic dadding of the laser fibre and drcumscribes the dadding ready for stripping. The stripping blades 4 are also positioned at a fixed distance horn the deaving blade 5 to remove the same length of cladding every time the laser fibre is deaved and stripped for each laser fibre size.
The second part of the lid 3 holds the cleaving blade 5. When the lId 3 Is closed the cleaving blade 5 deaves the overhanging end of the laser fibre.
The piece of glass and plastic cladding Is caught in the compartment 6 In the base 1. Lid 3 that holds the deaving blade 5 has an overlapping edge 7. The overlapping edge 7 holds lid 2 dosed as well as acting as a guard to protect fingers from the deaving blade 5.
The laser fibre is deaved and stripped by opening both lids 2 and 3, placIng the laser fibre in the correct size groove 8 so the end of the laser fibre overhangs the compartment in base 1. Lid 2 is then dosed to secure and drcumscnbe the fibre cladding. The second lid 3 is now dosed to deave the laser fibre and hold lid 2 securely dosed. Firm pressure is then maintained on both lIds 2 and 3 and the laser fibre is pulled from the cleaver and stripper device. The laser fibre is thus deaved and stripped ready to continue laser surgery.
The blades 4 Figure 2 are pre-cut to an exact size for each laser fibre size in order that only the plastic cladding of the laser fibre is cut and not the glass core of the laser fibre. palms
