In this guide 6 sections
Buy a ready product for the standard parts of an implant maker’s work, such as stock, purchasing and documents. Build custom only where your process is unusual, such as surgeon set loan records or serial tracing from bar stock to patient. Most makers end up with both, joined by one lot number.
Split the work into standard and unusual
Start by listing what the business does, line by line. Purchasing, invoicing, stock and payroll look alike in every factory. A ready product covers them well. It costs less than writing them again.
The unusual part is what an auditor and a surgeon ask you about. Which bar-stock heat produced this titanium stem? Which passivation bath? Which instrument set went to which hospital last month?
Draw a line between the two lists. Be blunt. The build-or-buy question then shrinks to the second list.
- Standard: purchasing, stock, invoicing, accounts
- Unusual: serial tracing from bar stock to finished implant
- Unusual: loaner set tracking by hospital
- Unusual: special process records by lot
Implant lot tracing is the test
An implant carries a serial or lot number that must lead back through machining, cleaning, passivation, marking, packaging and sterilisation. It must also lead back to the material certificate and the mill heat.
Ask each vendor to show this on a live demo using your own part, say a tibial tray, and give them a lot number. Then ask for the heat number, the CNC program revision, the inspection report and the sterilisation load.
If they answer with slides, you have learned something. Slides are not a trace. If they say a customisation is needed, ask who writes it and how upgrades treat it.
Sterilisation and surgeon sets
Many implants ship sterile after gamma or ethylene oxide treatment at an outside facility. Your records must hold the load, the dose or cycle report and the release date. Implants shipped non-sterile need a different path, with cleaning instructions for the hospital.
Surgeon sets are the odd one out. A set holds trays, trials, inserters and implants, travels to a hospital for a case, returns, and is cleaned and inspected before the next loan. Ready products built for factories rarely track a set by tray and by hospital.
This gap is often the strongest case for a custom module. Test it first.
- Sterilisation load and release record
- Set contents by tray and part
- Loan, return and inspection dates
- Missing or damaged instrument log
Weigh cost, change and ownership
A ready product starts sooner and has a known upgrade path, and you adapt to its screens. A custom build fits your process, but you carry maintenance and need someone who knows the code.
Ask who fixes defects at night before a shipment. Ask who holds the source files, and how each change to the lot trace is documented. Quality systems expect changes to software that holds records to be controlled and tested.
A middle route works for many makers. Buy the standard core, then build the lot trace and the set tracker as a separate piece that reads the core’s part and lot numbers.
A decision to take this month
Write a one-page requirements list with the ten questions your auditors and surgeons ask most, such as heat number, sterilisation load and loaner set location. Mark each one as met by a ready product, met with configuration, or needing custom work.
Show that list to two vendors and one developer, then compare their answers on the unusual items only. The price of the standard items will be similar across vendors, so spend your time on the differences.
Build or buy decision grid
A grid on one page with ten rows, one per question an auditor or surgeon asks, such as heat number lookup or set location. Columns mark ready product, configuration, custom work, the owner of the answer and the vendor’s demo result. A bottom block holds code ownership and support questions.
Open a blank worksheet to printQuestions owners ask
Can a ready product handle serial tracing?
Some can, within limits. Test it with a real part and a real lot. Ask the vendor to trace from finished serial back to the bar-stock heat on screen.
Is custom work always slower?
Not always. A small, focused module can be quicker than configuring a large product. Scope matters more than the label.
What about validation of the software?
Software that holds quality records needs documented testing, whether bought or built. Ask each vendor what validation support they provide, and plan the time.
Should surgeon set tracking be separate?
Often yes. It follows a loan cycle, not a production order, so a separate module linked by part and lot number can be simpler to run.
