Esy®-Hook

Esy®-Hook

With the growing prevalence of minimally invasive surgery (MIS), the importance of retractors used in these surgeries is widely recognized. Moreover, the current situation also considers the need for securing medical personnel and managing costs during surgery.

The Esy®-Hook was developed as a solution to address these challenges. It is designed to maximize the surgical field visibility for the surgeon while ensuring smooth retention of various retractors.

Background and Concept of Esy®-Hook Development

As minimally invasive surgery becomes more common, the significance of retractors used in these procedures is now well understood.

Additionally, the challenges of managing surgical staff and controlling costs are also taken into account.
The Esy®-Hook was created as a solution to these issues, designed to optimize the surgical field and provide smooth retention of various retractors.

Concept

  • Low Profile Design: Maximizes surgical workspace.
  • Simple Structure: Single-hook shape and one-way slide function improve operability.
  • Versatility: Suitable for a wide range of surgeries, not just orthopedic hip surgeries.
  • Cost-Effective: Ideal for surgeries with fewer personnel.

Esy®-Reamer

Esy®-Reamer

TThe positioning of the Acetabular Cup in Total Hip Arthroplasty (THA) is based on various concepts developed by orthopedic surgeons, and the method of placement significantly influences postoperative clinical outcomes. In the short term, it affects the initial fixation and dislocation of the cup, while in the long term, it impacts the wear of the implant and the long-term stability of the shell and stem.

Background and Concept of Esy®-Reamer Development

The position of the Acetabular Cup in THA is determined according to different concepts by orthopedic surgeons, and the placement technique has a direct impact on clinical outcomes after surgery. In the short term, it affects initial fixation and dislocation, while in the long term, it influences implant wear and the long-term stability of the shell and stem.
Furthermore, the positioning of the cup affects the hip's rotation center, which influences femoral offset and the biomechanics of the hip joint.

Concept

  • Accuracy : Supports reaming to the pre-planned position (mainly addressing initial reaming depth issues).
  • Safety : Features a stopper function for added safety.
  • Cost-Effectiveness : Potential for reduced surgical time.

Design

  • Esy-Reamer Standard is designed to cut approximately 8-12 mm thick bone.
  • Esy-Reamer Shallow is designed for cutting approximately 5-7 mm thick bone.
    (Note: Small variations may occur depending on bone quality.)
  • Navigation systems: The blade’s position should ideally be set to Φ47mm.

Esy®-Revision Blade

Esy®-Revision Blade

In cementless femoral stem removal during hip joint revision surgery, traditional methods often involve using thin chisels and hammers to carefully separate the bone-stem interface. The Esy®-Revision Blade is designed to be attached to a reciprocating saw, allowing for smooth separation of the bone-stem interface through axial movement of the femur.

Background and Concept of Esy®-Revision Blade Development

The Esy®-Revision Blade features a full blade design for proximal (short) applications, which are more visible, and a design with a reduced cutting surface for distal (long) applications, making it easier to avoid excessive bone removal. The blade has been designed to ensure it does not penetrate the bone too easily, especially in the medullary cavity, considering elasticity and optimal blade thickness and width.

Concept

  • User-Friendly : Smooth separation when attached to a reciprocating saw.
  • Safety : Designed to prevent excessive bone penetration with appropriate blade thickness and width.
  • Cost-Effectiveness : Potential for reduced surgical time.

Esy®-Positioner

Esy®-Positioner

In Total Hip Arthroplasty (THA), the patient's position is typically either lateral or supine. The Esy®-Positioner was developed to allow for a unique and new position known as Antero Lateral 60° (AL60). This tool enables quick and precise positioning of the AL60 during THA, providing optimal access and stability.

Concept

  • Speed : Enables faster AL60 positioning compared to traditional pelvic fixators.
  • Safety : Minimizes moving parts in the pelvic fixator to prevent instability during positioning.
  • Accuracy : AL60-specific pelvic angle gauge ensures accurate positioning with reference to the anterior superior iliac spine (ASIS).
