OHST Hip Prosthesis Surgical Hand Instruments Set Analysis Report

Device Identification and Areas of Use

The products in the image are a set of surgical hand instruments used in hip prosthesis (arthroplasty) surgeries in the orthopedics and traumatology branch. These instruments are designed to prepare the patient’s bone structure for the prosthesis (reaming and rasping) and to insert (impact) the prosthesis components into the bone. The set is organized within two separate metal sterilization baskets.

Brand and Model Identification

Based on the handwritten information note at the bottom of the image, the brand of the set has been identified as OHST. The note states that the product is of German origin. No specific readable model number is found on the instruments.

Originality Assessment

The metal craftsmanship of the surgical instruments, the structure of the rasping and reaming surfaces, and the material of the handles used are compliant with professional medical equipment standards. The general appearance of the products supports their originality as surgical equipment.

Quantity Information and Content Analysis

The set consists of numerous pieces within two stainless steel wire sterilization baskets. The counts and identifications made from the image are as follows.

Upper Basket Contents

• 14 spherical, perforated acetabular reamer heads of various diameters.
• 2 long-shafted, mechanized holding hand instruments.
• 1 surgical scissor or clamp-like instrument.
• 2 white cylindrical pieces with the numbers 42 and 70 on them.
• Spherical heads in green, blue, and gray colors, and various screws.
• 1 small transparent pouch with contents not fully understood.

Lower Basket Contents

• 6 femoral rasps of various sizes.
• Percussion and guiding hand instruments of various lengths with brown handles.
• 1 hand instrument with a T-shaped handle.
• 1 surgical mallet with a white plastic tip.
• Various metal connection and impaction attachments.

General Condition and State

The surgical instruments are in used condition. The general condition of the instruments is good. There are usual dullnesses on the metal surfaces due to autoclave sterilization and surgical use. The overall integrity of the set has been preserved.

Physical Deformation and Mechanical Components

No breaks, cracks, or dents have been observed on the bodies of the instruments, the toothed surfaces of the rasps, or the cutting edges of the reamers. There are superficial color changes and minor scratches on the brown and white handles due to use. The connection points between the handles and the metal bodies appear solid. There are usual wear marks on the plastic tip of the surgical mallet due to impact.

Size and Compatibility

The numbers 42 and 70 are readable on the white cylindrical pieces located in the upper basket. These numbers likely indicate diameter or measurement in millimeters. The reamer heads and rasps are arranged in sequential sizes from small to large to accommodate different patient anatomies.

Label and Document Information

No directly readable laser marking, serial number, or barcode can be discerned on the instruments in the image. At the front bottom of the baskets, there is a paper with handwritten text: OHST (GERMAN) HIP PROSTHESIS INSERTION + IMPACTION SET. Behind this paper, there is an upside-down printed cardboard piece not directly related to the product. No official invoice or warranty document is visible in the image.

Existing Faults and Potential Fault Risk

No existing faults such as a broken part, missing mechanism, or rust that would prevent the use of the instruments have been detected in the images. The condition of the instruments appears sufficient and safe for surgical procedures. Since no serious wear and tear has been observed, no potential fault risk is foreseen.
