LASERS
MULTIPULSE TM+1470(Thulium) 120 W
JenaSurgical introduces MultiPulse Tm+1470 the last generation thulium laser, unmatched in terms of efficiency, accuracy and safety in multiple surgical application fields. MultiPulse Tm+1470 is the only system that combines a 1,940 nm Thulium laser with a 1,470 nm diode laser (maximum power 120 W + 30 W), designed to deliver the best performance in the operating room.
Unmatched in terms of efficiency, accuracy and safety.
The choice of emitting at 1940 nm is not accidental. This wavelength is absorbed by water more than 1st generation Thulium at 2040 or Holmium at 2100 nm.
To have a more significant coagulation effect, MultiPulse Tm +1470 is integrated with a 1,470 nm Raman laser, which can be combined as desired in the same fiber optics.
When a greater coagulation effect is required, it is sufficient to change from the “cutting-mode” to the “coagulation-mode”, selecting the 1,470nm diode only by pressing a different pedal. The pedal control allows the surgeon to select the required mode without changing the laser fiber and without looking away from the operating field.
The ability to mix or separate these two wavelengths, combined with the innovative technological solutions of MultiPulse Tm+1470, allows optimization of the laser beam interaction with the tissue. This ensures perfect vaporization and better hemostasis when cutting, using less working power and thus minimizing residual carbonization. Moreover, in addition to the continuous mode (CW), the MultiPulse Tm+1470 thulium laser system can work with pulsed emission, to operate with maximum precision and delicacy even in those areas that require “colder” action.

Urethral Stricture
Treatment of urethral stricture, resulting from spongiofibrosis due to different causes such as inflammation or trauma, can now be quickly and effectively treated with holmium laser urethrotomy using MultiPulse Ho. This minimally invasive and safe procedure is suitable for short urethral strictures as well as for more significant strictures or for the treatment of urethral atresia. The laser ablates damaged tissue with a clean cut, free of bleeding and without penetrating too deeply. This reduces the risk of lateral thermal damage, complications, recurrences or the formation of post-surgery fibrosis, resulting in complete restoration of normal urinary flow.
The MultiPulse Ho system is also an excellent tool for ablation procedures, incision and coagulation of soft tissue, providing maximum operating control and minimal damage to adjacent areas. It offers a wide set of applications in surgery for tumors in the bladder, urethra, ureter and kidney.
UROLOGY
The continuous progress in surgical lasers with fiber optics, combined with the widespread use of miniaturized endoscopic instruments able to go where a hand or scalpel could never reach, makes laser surgery the best support for the urologist and for the development of endourology.
Especially holmium and thulium lasers offer advanced performance with a lower intraoperative bleeding risk and shorter hospital stays and catheterization of patients,making endoscopic procedures safer and less invasive than traditional surgical techniques and open surgery.
Endosurgical laser treatments for BPH
BPH (Benign Prostatic Hyperplasia) – The laser has been used since the 80s for the treatment of BPH: after several evolutions of laser sources and surgical techniques, today the holmium laser and the more recent latest generation thulium laser, are the most advanced technology and high performance tools for endoscopic prostatectomy procedures.
In the beginning the pulsed Ho:YAG laser, with its wavelength of 2100 nm (well absorbed by the water contained in tissues), was usedfor the vaporization of the prostate, through HoLAP (Holmium Laser Ablation of the Prostate), an ablation procedure that is easy to learn but does not produce great results especially for large prostates. Subsequently HoLEP (Holmium Laser Enucleation of the Prostate) was developed: an enucleation technique that, with the help of the morcellator, enables treatment of BPH, regardless of the size of the adenomas. In recent years, a new laser source has gained popularity after holmium: the thulium laser. The arrival of the second generation of 1.9 µm Thulium laser, combined with a 1470 nm diode, helped further spread the use of ThuLEP (Thulium Laser Enucleation of the Prostate).
The MultiPulse HoPLUS and MultiPulse Tm +1470 systems by JenaSurgical represent the latest technology available today to urologists for transurethral operations, enabling them to operate on a prostate of any size for a precise adenoma removal at the surgical capsule level. These devices are excellent, minimally invasive, effective and safe alternatives to traditional TURP and open prostatectomy. The prostate enucleation e with Ho:YAG or Thulium + 1470 diode laser is less prone to recurrences or complications (such as TUR syndrome or bleeding during and after surgery) and involves shorter periods of catheterization and hospitalization. Thanks to their excellent hemostatic effect, they are recommended in the case of surgery on cardiopathic patients or those with coagulation problems (e.g. under those being treated with anticoagulants). Moreover, the use of the morcellator, unlike other procedures, allows for histopathological analysis to be performed on excised tissue in all cases.
Endoscopic Lithotripsy and Treatments for Stones in the Urinary System
Even for the surgical treatment of urinary tract stones, the development of holmium lasers has offered safer and minimally invasive alternatives compared to traditional lithotripsy techniques.
Due to this, the JenaSurgical product range includes holmium systems with fiber sets specially developed for laser endoscopic lithotripsy such as MultiPulse Ho (35W) and MultiPulse HoPLUS (140W), which support urological surgery for the treatment of a wider range of diseases.
The various lithotripsy techniques are used from time to time according to the shape, size, chemical composition and the anatomical location of the stone to be treated. The patient’s symptoms and condition such as the presence of stenosis of the urinary tract are two other important criteria for choosing the procedure. The major advantages of using a Ho:YAG laser source like the one supplied with MultiPulse Ho and MultiPulse HoPLUS consist of high efficiency for all types of stones and the low percentage of migration and retrograde propulsion of fragments treated.
If ureteroscopy (URS) is suitable for the surgical treatment of different types of ureteral stones, RIRS (Retrograde Intra-Renal Surgery) can be considered as the evolution of URS which, using latest generation endoscopes, also treats many kidney stones. Using a flexible ureterorenoscope with active and passive deflection, it is possible to reach the kidney cavity backwards.
Neither of these procedures requires incisions: a ureteroscope or a ureterorenoscope is directly inserted through the urethra into the bladder, ureter and then, when necessary, in the kidney channels. The laser light is delivered via a flexible fiber optic inserted in the endoscope until it enters in direct contact with the stone. Here the energy emitted by holmium can bring about the pulverization or fragmentation. In the first case, the residue is subsequently expelled spontaneously with urination; in the second case, the fragments are collected and removed using special probes called “stone baskets”.
Percutaneous nephrolithotomy (PCNL) is the procedure most often used for larger kidney stones or for those of harder consistency. Under general anesthesia, a small incision is made on the patient side at the level of the kidney, for the direct passage of a nephroscope that brings the laser in direct contact with the kidney stone for fragmentation. When the operation is completed, a special inner catheter (double- J stent) is inserted, to function as a link between the kidney and the bladder to allow the outflow of urine, thus avoiding the occurrence of colic.
Urethral Stricture
The development of more effective and long-lasting treatments for urethral stricture, using minimally invasive and safe procedures, continues to be an important research area. These fibrotic strictures of the urethra, resulting from spongiofibrosis originating from different causes such as inflammation or trauma, can now be quickly and effectively treated with thulium or holmium laser urethrotomy using MultiPulse Ho, MultiPulse HoPLUS or MultiPulse Tm+1470. The use of the laser is suitable for short urethral strictures as well as for more significant strictures or for the treatment of urethral atresia. The laser performs the ablation of the damaged tissue with a clean cut, free of bleeding and without penetrating too deeply. This reduces the risk of lateral thermal damage, complications, recurrences or the formation of post-surgery fibrosis, resulting in complete restoration of normal urinary flow.
Tumors
The laser is an excellent surgical instrument widely used in surgical oncology. In urology, both the Ho:YAG and the Thulium lasers can be used for the excision of tumors of the urethra, bladder, ureter and kidneys. The use of wavelengths that are transmitted through fiber optics allows the work to be performed easily endoscopically. By suitably adjusting the parameters, precise control of both the cutting and ablation is achieved. In particular, the MultiPulse Tm+1470 system allows for quick work with an excellent hemostatic effect (it can be adjusted simply using a pedal according to need, by appropriately mixing the two wavelengths 1940 nm and 1470 nm) and extremely reduced thermal damage to the surrounding tissue.
