Dr. Oppel 501

Description

What is the 4MHz Radio Frequency Surgical Unit?

Dr. Oppel’s electrode is not being heated by itself. Electrode lets the cellular tissue produce the joule heat, and operates hemostatis, cutting, and coagulation. 4MHz radio frequency makes possible precise cutting and deep coagulation even in blood.

There is no carbonization and damages to the surrounding cellular tissue by electric spark, and the safety secured.
Specially developed various Bipolar and Monopolar electrodes for OB/GYN, PS/DER, Urology has outstanding performance in Micro Surgery by their excellent output time function.

Radio Frequency – OBGYN

Radio frequency coagulation for Cervical Erosion

The mechanism of erosion cure

When columnar epithelium is defected in a special way, the erosion is cured by ingression of the near squamous epithelium.

Cause of residue and relapse of columnar epithelium in erosion cure

 

Since there are lots of unexpected cases when nabothian cysts are deeply formed in a patient’s cervix, even though columnar epithelium is defected with drug, cauterization, and cryosurgery, the perfect cure is said to be hard due to the difficulty of ingression of squamous epithelium resulting in insufficient removal of columnar epithelium.

For perfect removal of erosion, 5mm depth of coagulation is needed.

 

 

 

What is RF coagulation?

 

 

 

It’s a way of coagulation necrosis to the 5mm depth of tissue, when the radio frequency current flows from electrode, passing tissue, to the patient plate, by producing joule heat on the tissue itself close to electrode. It’s very hard to make necrosis with cauterization or cryosurgery because no deep coagulation is capable. However, coagulation necrosis is perfectly achieved in the coagulation with radio frequency current because electrode lets the tissue itself produce joule heat.

 

 

Coagulation range

 

 

First, insert 6mm semi-ball type electrode into the os to 1-1.5Cm depth and start coagulation until boiling noise is heard, and then rotate electrode and slide all areas of erosion. In addition, perform coagulation on the normal squamous epithelium of ectocervix region to be 2mm-5mm overlapped.

 

 

Self control of coagulation depth

 

 

The coagulative depth is decided by the electrode size and the device is designed to make different coagulation depth by the electrode size as above

 

 

Radical Conization by HFSU

Coagulation is performed for bleeding control and necrosis of the remaining lesion after conization.

Biopsy by conization

Procedure of radical conization

Place patient plate and carry out vaginal douche
1. Start Conization from the part where no lesion is inferred to exist.
2. Turn the Conization electrode 180 degree – Change the position of your hand.
3. Turn it 180 again.
After the Conization, coagulate the cut part widely by E01 (6mm bent electrode) to stop bleeding and necrose the lesion remains.

Procedure of LLETZ/LEEP

Operation progress

Healing progress

 

Pain during operation

As a rule, no anesthesia is needed. At times, there are some patients who feel painful, but most are operated easily without anesthesia. Only nulliparous woman is occasionally needed for that.

Late Bleeding

If the coagulation depth is shallow, necrosis region could be not enough and bleeding could occur due to vascular exposure. In this case, columnar epithelium is still remaining and squamous epithelium isn’t repaired. The important thing, in this case, is to perform coagulation to the 5mm depth with care in an early stage of the practice. In addition, warn the patient to be careful not to have necrosis region seperate by exercise or sexual intercourse. Therefore, to prevent late bleeding, it is required that the necrosis region should be remaining without seperation for 3 weeks until the blood vessel closes up.

Side effects

No report has been made about side effects such as infertility and atresia of cervix caused by excessive coagulation.

 

Radio frequency conization for CIN lesion

Special Points
1. Capable of a simple operation on an outpatient basis.
2. Tissue sample is used for pathology reading.
3. No general anesthesia is needed. Conization procedure takes only several seconds after local anesthesia.
(10 seconds in conization and 3-4 minutes in coagulation).
4. Various angles of conization probes.
5. Perfect bleeding control.
6. No suture is needed after conization.
7. Short healing period (4-6 weeks).
