NAJUTA
NAJUTA is a custom-made fenestrated stent graft designed according to each patient’s aorta shape and location of branch vessels.
By creating a fenestration in the stent graft, the NAJUTA can treat arch aneurysms involving the great vessels.

OHKI BAUM is a multi-functional device with tweezer functions at the tip of the scissors that enables cutting, spreading, cautilizing and grasping with one device.
When exposing the femoral artery during this case, a variety of functions of the OHKI BAUM can be seen.

Radio lucent wound retractor
Conventional wound retractors appear and distort X-ray images, but this retractor is designed to let X-rays pass through so it will not obstruct the X-ray images.

〈　Surgical point　〉
if possible, preoperative mapping using ICG photodynamic lymphangiogram
Local anesthesia (painless) for talk with patients
minimal incisions
Detection and dissection for lymphatic channels under loops or operation microscope
Accurate supermicrosurgical vascular anastomosis for lymphatic channel and vein
Multiple lymphovenous bypass
Bloodless surgery using Xylocaine with adrenalin

〈　About medical devices　〉
30G needle for injection (Nipro and Termo): For painless local anesthesia.
Loops with prism (Hoya): microvascular detection and dissection for lymphatics and subcutaneous veins. Protection for surgeon’s neck spine.
Supermicrosurgical instruments (Emi): supermicrosurgical dissection and anastomosis for lymphatics and vein.
Supermicro-needle (Crown Jun): 50 micron needle (12-0) for anastomosis of 0.3-0.5 mm vessels.
Mitaka’s operation microscope: dissection and anastomosis for lymphatics and veins.

〈　Surgical point　〉
1) The side-plate prevents postoperative displacement, especially varus displacement.
2) Compression can be applied between fragments by a screw and barrel mechanism.
3) This is an accurate and reproducible procedure with a small incision and short operation time using sophisticated instruments.

〈　About medical devices　〉
The screw and barrel mechanism is perioperatively compressed between the fragments.
In addition, a one-holed plate barrel strongly prevents postoperative displacement of the femoral head, especially varus displacement.
Sophisticated instruments enable a quick and accurate procedure by small incision.
These implants can be applied to both displaced and non-displaced femoral neck fractures and have been used for over ten years in Japan.

〈　Surgical point　〉
1) Before procedures, adequate preoperative reduction and verification is necessary.
2) The "true lateral view” technique allows optimal insertion of implants into the femoral head
3) Fid-blade prevents intra- and postoperative displacement of the femoral head, especially rotational displacement.

〈　About medical devices　〉
Magnum nails can be used in all trochanteric fractures except for those involving the low subtrochanteric area.
As the simple Fid-blade is driven into the femoral head through an uncomplicated maneuver, postoperative displacement, especially rotation of femoral head, is prevented.
In addition, the Magnum nail is designed based on detailed anatomic data, so adaptation of implants is ideal in most cases.
The Fid-blade can be inserted in optimal position within the femoral head by a technique using true lateral view.

Total Knee Arthroplasty（TKA) for Medial Gonarthrosis.
By measuring the internal tissue balance using the "modified gap technique", artificial joints are developed to match the Asian skeleton.
In this video, you can see Japanese elaborate TKA procedures and products.

Laparoscopic subtotal gastrectomy performed by Dr. Naoki Hiki, MD, PhD at the Cancer Institute Hospital of JFCR.
Surgical blood loss is minimized in the procedures of a Roux-en-Y anastomosis and D1+ dissection.

Transanal Total Mesorectal Excision (TaTME) for colorectal cancer
TaTME is the focus of attention globally in colon surgeons’ society, as an advanced minimally invasive surgery for colorectal cancer.

In this video, TaTME is applied to a case of lower rectal cancer under the aid of laparoscopic procedure, and colo-anal anastomosis is conducted by hand sewing.

It is our great privilege to introduce Japanese advanced medical operation, implemented by excellent surgical techniques as well as their supporting devices made in Japan.
