Overview

What Is a Litho Sheath?

A litho sheath is a reusable urology instrument component that provides an access and protective channel for a compatible endoscopic stone-management instrument system. Depending on its design, it may accommodate a telescope, obturator, stone punch, lithotrite or another system-specific working component.

The term “litho sheath” is used for different configurations in the market. It should not be assumed to describe one universal size, connector or instrument interface.

A litho sheath must be matched with the complete system rather than ordered by its French size or appearance alone.

Compatibility Notice

Similar dimensions, appearance or brand-type wording do not prove mechanical or functional compatibility. A brand-type reference does not mean the product is manufactured by the referenced OEM, fits every model produced by that company, or indicates endorsement by the trademark owner. All third-party trademarks remain the property of their respective owners.

Clinical selection and use must follow the applicable instructions for use and institutional protocols.

Product Range

Bharat Surgical Litho Sheath Range & Components

Bharat Surgical lists Litho Sheath as a dedicated category within its urology instrument range. The current public category page does not state exact sizes or model-specific specifications.

Configurations & Comparisons

Obturator, Stone Punch & System Differences

Litho Sheath with Obturator

A litho sheath may be supplied or quoted with a matching obturator. The obturator must correspond to the sheath’s nominal French size, usable working length, internal geometry, distal profile, proximal locking mechanism, and manufacturer or system series.

An obturator from a visually similar sheath should not be used unless compatibility has been established. A loose, incomplete or incorrectly matched connection indicates that the assembly requires further technical review.

Litho Sheath and Stone Punch Compatibility

Bharat Surgical also publishes a stainless-steel or brass urology stone punch set with an obturator. However, this does not mean that every litho sheath fits every stone punch. When sourcing a sheath for an existing stone punch, provide:

Stone punch manufacturer
Exact product or catalogue number
Existing sheath size
Working length
Connection and locking photographs
Obturator details
Telescope details, where applicable
Required irrigation arrangement

ObturatorMust match the exact litho sheathMust match the exact cystoscope sheath
InterchangeabilityNot assumedNot assumed
Procurement priorityWorking instrument, telescope, sheath and obturatorTelescope, bridge, sheath and obturator

A cystoscope sheath should not be substituted for a litho sheath solely because the French size appears similar.

Litho Sheath vs Lithoclast Sheath

The names are sometimes used inconsistently by buyers and suppliers. A “litho sheath” may refer to a sheath for a mechanical lithotrite, stone punch or another stone-management system. “Lithoclast” may refer to a particular type or brand of stone-fragmentation equipment. Before quotation, the buyer should identify the exact device and intended interface.

Technical Sizing

Irrigation Flow, French Scale & Optical Integration

Standard and Continuous-Flow Configurations

Depending on the system, a litho sheath may have a standard irrigation arrangement or separate flow paths.

Standard-Flow Configuration: A standard sheath may have one defined connection for fluid management according to the system design.

Continuous-Flow Configuration: A continuous-flow arrangement may use separate inflow and outflow connections, inner and outer sheath components, multiple stopcocks, and model-specific seals and connectors. The selected configuration should be checked against the telescope, working instrument and facility’s approved fluid-management equipment.

Understanding French Size

Litho sheaths may be specified in French size, abbreviated as Fr. French size is converted into nominal millimetres using: Diameter in millimetres = French size ÷ 3.

French sizeApproximate mathematical diameter
18 Fr6.0 mm
21 Fr7.0 mm
24 Fr8.0 mm
25 Fr8.3 mm
26 Fr8.7 mm

These figures explain the French scale only. They are not Bharat Surgical litho sheath specifications and should not be used as proof of availability or compatibility. The exact outside diameter, internal bore, working length and dimensional tolerances should be confirmed in the final product specification.

Telescope Compatibility

Where the litho sheath is used with a rigid telescope, confirm:

Telescope manufacturer
Telescope model or catalogue number
Outer diameter
Working length
Viewing angle
Proximal connection
Light-post type
Sheath locking interface
Working-component interface

Two telescopes with the same nominal diameter may differ in working length, viewing angle and locking geometry.

Obturator & Port Configurations

Before ordering an obturator, confirm litho sheath model, French size, sheath length, tip profile, locking mechanism, instrument-system manufacturer, and existing obturator markings.

Depending on the model, litho sheaths may include fixed irrigation ports, removable stopcocks, one-way stopcocks, two-way stopcocks, separate inflow/outflow ports, or model-specific tubing connectors.

Care & Checklist

Materials, Reprocessing & Compatibility Checklist

Material and Construction Considerations

Reusable litho sheath configurations may contain stainless-steel components along with model-specific seals, valves, stopcocks or other materials. The precise material grade should be confirmed in the technical quotation.

Hospital and distributor buyers should evaluate sheath straightness, surface finish, internal-channel finish, wall condition, distal-end profile, locking accuracy, obturator alignment, stopcock movement, seal condition, channel patency, corrosion resistance, product identification, and reprocessing compatibility.

Reusable Status & Autoclaving

A reusable litho sheath must be cleaned and reprocessed according to its current product-specific instructions for use. Reusable status does not mean that every cleaning agent, ultrasonic process or sterilisation cycle is suitable. Read the FDA’s reusable-device reprocessing information.

Steam sterilisation should be used only when the manufacturer’s validated instructions permit it for the exact sheath and all its components. Confirm permitted sterilisation method, required disassembly, cycle parameters, chemical compatibility, seal and stopcock compatibility, drying requirements, packaging/tray requirements, and any stated service-life limitation.

Cleaning must precede sterilisation or high-level disinfection because retained soil can interfere with the process. See the CDC disinfection and sterilisation guideline.
