Medical Devices and Components

The products manufactured by making full use of abundant know-how and expertise of MaruhoHatsujyo.

Coiling

Torque Coil (Multiwire-Multilayer Coil)

The coil retains super flexibility with appropriate pushability. Even if the coil is bent, it can transmit the torque by synchronizing the root and the tip.

Marking
Application example(Neck oscillation rings of endoscope)*Patent number:3530011

This section is composed by multi layered link-less rings. Thus, it secures a large working channel within its diameter. And it also contributes to miniaturization of the endoscopes.

Electro Polishing

Role

  • Materials:Ni-Ti,SUS,CoCr,Ti etc.
  • Possible to polish the surface up to 0.1μm, surface roughness (Ra).

Integrated production at Maruho Hatsujyo
from laser cuttingto electro polishing.

Other Processing Technology

Brazing

Brazing a coil terminal finely, and then the end face can be processed in cutting work such as stepped processing.

Rolling

Board thickness of 20μm at minimum.
Stable processing is possible up to 1:5 = board thickness: board width.

Other medical equipment (under development)

We develop a variety of medical equipment and prototypes by applying the technologies we have built over the years.
