Surgery

Surgical applications include urology, cardiovascular

and veterinary surgery. Lasers offer an advantage

because the high intensity can cut tissue and

coagulate blood at the same time.

 

Researchers have demonstrated that

laser surgery results in the removal

of much less tissue than traditional

procedures, improving

patient recovery.

There is a diverse range of surgical applications that utilize lasers in the operating room.  From general surgery to surgical specialties, surgeons use lasers to cut, coagulate and remove tissue. Depending on the laser type, wavelength and delivery system, lasers oftentimes replace conventional surgical tools due to their better outcomes in wound healing.

Lasers are used for surgical applications in either contact or non-contact mode. In the former case, laser radiation heats up a specially designed surgical tip, which, in turn, is used to cut tissue through thermal conduction. Diode lasers are well suited for this mode of operation. Alternatively, in the non-contact mode, wavelength  of the laser source is selected to utilize high water content of most soft tissues.  Erbium-doped fiber lasersThulium-doped fiber lasers and Mid-IR hybrid lasers have demonstrated their suitability for this mode of operation.

Cardiovascular Surgery
Transmyocardial revascularization (TMR) is a surgical procedure to treat angina (chest pain). TMR uses a laser to create channels in heart muscle and restore blood flow. The ease of use of a Ho:YAG fiber laser delivery system allows the surgeon to perform the procedure through a catheter.

Urology
Benign prostatic hyperplasia is a urological condition that is caused by an enlarged prostate gland.  Surgeons use a laser to remove the prostate tissue and improve flow into the urethra. IPG’s Thulium fiber laser has demonstrated positive outcomes for this application.

Another widespread urological application is lithotripsy. Ho:YAG laser is de facto standard of care for this procedure, whereas potential of QCW thulium fiber laser is currently being explored.

Laser-assisted Cartilage Reshaping
Laser-assisted cartilage reshaping (LACR) is a procedure that is gaining popularity to correct defects of cartilage shape through laser heating and subsequent mechanical correction. Diode lasers are a good choice as a laser source for this modality.
