Stryker System 4 Single Trigger Rotary Handpiece.
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Symptoms: Handpiece runs slow, stalls when drilling / cutting, or does not run at all.
Root cause: Worn motor / turbine, worn gears / bearings, a low or aged battery, or (pneumatic) low supply pressure / a worn hose.
Symptoms: Handpiece or attachment gets hot quickly, burn / thermal-necrosis risk.
Root cause: Worn bearings / gears, a dry / seized attachment, or over-duty use.
Symptoms: Few cases per charge, will not reach full charge, sudden shutdown.
Root cause: Aged battery pack or a charger fault.
Symptoms: Bur / blade / pin slips or will not lock, attachment wobbles, quick-coupler worn.
Root cause: Worn chuck / collet or coupling.
Symptoms: Speed will not vary, forward/reverse or oscillate will not select, trigger sticks.
Root cause: Worn trigger / control mechanism or its seals.

Due to potential for tourniquet cuffs to detach from the bladder at the welding connection and result in the cuff not being able to maintain pressure.
Due to manufacturing issue, reprocessed shears, may become stuck in the "on position" resulting in continuous activation.
Tourniquet cuff flange may become detached from the bladder. If leak occurs during the procedure, there may be risk of hemorrhage, resulting in blood loss greater than expected. Other serious risks include cerebral hypotension and cardiovascular collapse and arrest, risking stroke or death. Specific to IVRA, patient toxicity may also occur due to rapid systemic absorption of anesthetics.
Stryker Neurovascular has observed that devices with Out of United States (OUS) approved Instructions for Use (IFU) and Packaging Labels (pouch and carton), different configurations, have been erroneously distributed to customers in the US.
Mislabeling; tourniquet cuff packaging labeled as dual port single bladder but contains a tourniquet cuff single port single bladder.
Unreleased software was installed on customer systems resulting in the visual feedback on the screen to show the points to be off from the physical reference point of the pointer or suction.
Stryker Neurovascular is recalling their DAC- Distal Access Catheter -038 136cm, a Distal Access Catheter by removal. The reason for the recall is: the DAC Lot #0000486382 was released with out-of-specification endotoxin results.
Increased incidence of disposable tourniquet cuffs "not able to achieve desired pressure" and "not holding pressure" due to 1) Cuff fabric tearing during use, and 2) Pinched or unseated O-ring at the connection between the cuff, disposable fill line, and/or cuff hosing, which may lead to loss of vascular occlusion, which may lead to operative site blood loss, hemorrhage, or other complications.
Mislabeling; dual-bladder tourniquet cuffs are labeled as single-bladder inflatable cuffs.
Potential for the inner bit to contain a crack, that may or may not be visible, which may lead to metal fragments entering the surgical site and/or delayed disengagment during use.
Seal integrity of the blister pack may be compromised and sterility cannot be assured
There is a potential for the cuff to leak air leading to a loss of vascular occlusion.
Tourniquet cuffs are potentially mislabeled. If used may lead to (1) Device misuse during procedure (2) Inadequate Limb Compression Force.
Complaints have been received regarding difficulty in removing the driver from the screw. High driver removal forces can lead to the screw pulling out still attached to the driver. This could result in an additional anchor insertion site in the bone being used.
A design related issue can contribute to the device exhibiting brittle behavior. This behavior may result in fractures of the catheter shaft.
Stryker Instruments is voluntarily recalling specific lots of sterile MIS Toolsteel Burs because the burs may exhibit signs of corrosion.
Issue with the process for detection of leaking Pressure Tourniquet Cuffs (PTC). Leaking PTC devices may result in excessive blood loss requiring surgical or medical intervention or systemic leakage of local anesthetic during Bier Block requiring medical intervention.
Stryker Sustainability Solutions has received reports indicating that devices from one lot (lot# 3574704) were labeled as 100mm models (CB5LT) while the devices inside of the packaging were 75mm models (CB5ST).
Stryker Instruments is recalling the Stryker SelectCore Variable Throw Biopsy Device due to the potential for for the stylet to eject from the SelectCore device during actuation.
Stryker Instruments is voluntarily recalling the CBCII Wound Drains and Ambulating Bulb for a potential sterility breach in the packaging
The Color Cuff Sterile Disposable Tourniquet Cuffs with Quick-Connect Fitting may have an incorrect end-connector. A customer reported having received a luer connector instead of a quick connect fitting. An incorrect connector may lead to an inoperable system due to incompatibility with the Smart Pump.
Stryker received reports from the field of the impaction plate dissociating/fracturing from the main body of the broach handle.
Stryker has identified a potential for the auger and/or cannula to fracture when the Dekompressor is used contrary to the warnings in the Instructions For Use (IFU). Specifically, manually bending the cannula can weaken the device and may result in a fracture of the auger and/or cannula. This could result in the need for additional medical intervention to remove the broken piece, pain or loss of m
Stryker Osteosynthesis has become aware that LEFT GAMMA3 nails are marked as right nails.
When preparing plasma using VitaPrep, it was reported that a small amount of blood collected in the bottom of the centrifuge cup following the centrifugation step. Firm has since discovered that if blood is present in the Luer connection of the VitaPrep following the blood draw step, this blood could be displaced to the outside of the syringe when the VitaPrep cap is reattached to the syringe. T
Stryker Orthopaedics has become aware of the potential for the above noted Accolade Rasp Handle Assembly to fracture upon use.
Product was packaged with a four inch needle in stead of the correct five inch needle. There is a potential that the needle may not be able to reach the fracture site, which may require additional medical intervention. In addition, if the stylet needs to be changed and the additional stylet that comes in the package is used, this additional stylet is one inch longer than the needle. which could l
Stryker Orthopaedics has become ware that there is the potential for interpretation of the product labeling which may lead to an incorrect implant being used.
There is potential for a breach in sterility in the blister packaging. This can lead to the use of non-sterile product which, if contaminated, could lead to a patient infection.
Failure to infuse and potential compromised sterility: The seal on the tyvek tray cover may fail, compromising sterility, and the device may fail to infuse the drug, resulting in a loss of pain mitigation.
The label on one side on the Ray TFC Device (Ray Cage) is incorrect. It reads 20 mm x 26 mm instead of 20 mm x 21 mm.
Kit fibers may not illuminate along entire length, which may result in inadequate visibility of the urethral structures during surgery
