Maquet launches versatile Alphastar Pro OR table

Maquet has recently launched the new Alphastar Pro OR table.

Its modular design makes it suitable for all surgical disciplines. It has an extensive range of accessories that can be easily connected using the simple ‘Easy-Click’ system. This allows the rapid deployment of a broad range of socket-mounted modules. The accessories enable the table to be used for a wide range of patient sizes and for orthopaedic, traumatology, cardiology and neurosurgical interventions.

A new, multi-sectioned table top ensures the anatomically correct positioning of the patient and can be adjusted for the corresponding surgical intervention. 360° radiotranslucent carbon fibre modules enable intraoperative monitoring with imaging processing. Additionally, a seat plate extension can be connected to give optimal radioscopy of the urogenital area. The motor-powered, exceptionally stable, leg plates are a significant improvement, particularly with gynaecological and urological operations.

The flexible height adjustment, from 598 mm to 1120 mm, allows the surgeon to work in an ergonomic position during operations, whether seated or standing.

The OR table is controlled using an IR or cable-corded hand control and guarantees safe operation, even at critical phases of the surgical procedure. Safe handling is also possible with the illuminated keypad, even in darkened operating theatres.

BOWA’s NiteKNIFE – quick, efficient, safe

Conventional electro coagulation reaches its limit at vessels with a diameter of more than approximately 2 mm. In this case, haemostasis and a permanent sealing can only be achieved with ligation bipolar vessel sealing: the bunched vessels or tissue are gripped by a special instrument and pressed together under a constant, specified level of pressure.

With the new, quick ligation ARC 350L V2.6 this procedure lasts just 5 seconds on average and stops automatically when finished.

Bipolar vessel sealing with the reusable BOWA TissueSeal and NightKNIFE has several advantages over other procedure such as ligature, suture and the use of clips, including: quick preparation, quick and safe vessel sealing, no foreign bodies left in the area of the operation, and low costs. This means that there is a shorter operating time and less blood loss, which in turn means better care for the patient.

The integrated cutting function on the NightKNIFE takes away any inconvenient time loss caused by changing instruments in laparoscopic procedures. The angled and non-traumatic toothed tips of TissueSeal enable ultimative safe tissue grip in vaginal or open hysterectomy.

The reusable device reduces costs and is a particularly strong economic incentive for using the BOWA NiteKNIFE, TissueSeal and ligator ligation instruments.

The fields of application for these sealing instruments extend from numerous open and laparoscopic interventions to specialist areas of surgery, urology and gynaecology.

US FDA to review Hologic’s revolutionary 3D breast imaging

A US-based company, Hologic, has revolutionised breast imaging by developing 3D imaging of the breast through a process called tomosynthesis.

The US FDA announced recently that they were setting up a panel to look at Hologic’s Selenia Dimensions 3D digital mammography tomosynthesis system. Hologic says they expect FDA approval sometime next year. The product has been commercially available in Europe since the end of 2008.

Andy Smith PHD, physicist and author of a white paper on breast tomosynthesis, says: “There hasn’t been a revolution of this magnitude since the beginning of breast imaging. “There have been incremental improvements over the years, but really this is what is going to make a big difference in breast imaging.”

In tomosyntheses the breast is viewed from multiple angles, so 2 objects that are superimposed in 2D become separated in tomosysnthesis. Hologic’s system takes 15 images in an arc over the breast. These images are mathematically synthesised into a ‘tomogram’ which shows the breast tissue as layers. This shows an entire 3D restructuring of the breast providing an image of the breast every millimeter – so if the breast is 5 centimetres you end up with 50 one-millimetre slices that can be viewed up and down through the breast. These slices can be looked at individually or shown in dynamic ciné mode.

Tomosynthesis imaging consists of a series of low dose exposures, with every acquisition about 5-10% of a normal single-view mammogram. Because each exposure is low dose, it is essential that the image receptors have a high quantum efficiency and low noise. Because images are being acquired at a rate of several images per second, rapid imaging is a benefit of this procedure. Hologic says the scan is quick. It can do the entire tomogram in around five seconds.

The clinical benefits of digital breast tomosynthesis are improved diagnostic and screening accuracy, higher cancer detection rates, fewer recalls, fewer biopsies, greater radiologist confidence, and 3D lesion localisation.

Carestream Health showcases new DRX-1C detector

At the annual meeting of the American Healthcare Radiology Administrators (AHRA) in August, Carestream Health showcased their new Carestream DRX- 1C detector, the latest expansion to its family of imaging solutions based on its wireless, cassette-size DR detectors. The new detector uses a cesium iodide scintillator to deliver exceptional image quality, with DQE (detective quantum efficiency) that is substantially higher than the DRX-1 detector.

The Carestream DRX-1 system allows healthcare facilities to quickly and cost effectively upgrade existing analog x-ray rooms from film or CR systems to DR technology in less than a day

The new detector is wireless and cassette-size, and uses the same battery and electronics as the existing DRX-1 detector. Like the DRX-1 detector, the DRX-1C detector is designed to be used with all three DRX-based imaging solutions: the Carestream DRX-1 System, Carestream DRX-Mobile Retrofit kit and Carestream DRX-Evolution suite.

DRX-Mobile Retrofit Kit

Also at the show, Carestream Health announced that that DRX-Mobile Retrofit Kit, in addition to supporting select GE and Siemens mobile units, would soon be ready to support three Shimadzu systems, enabling these systems to convert to wireless DR technology. The retrofit kit can currently be integrated with GE AMX-4, GE AMX-4 Plus, Siemens Mobilett Plus, Siemens Mobilett XP and Siemens Mobilett XP Hybrid. Beginning in October, it will also support Shimadzu MobileArt, Shimadzu MobileArt Plus and Shimadzu Evolution.

SoftView technology improves visibility of soft tissue in the lungs

Siemens has enhanced its digital radiography systems with technology that produces a soft tissue image of the chest. Riverain Medical’s SoftView Enhanced Chest Imaging technology automatically suppresses the ribs and clavicles to improve the visibility of soft tissue structures in the lungs, allowing the physician to interpret pulmonary nodules with greater certainty. Furthermore, as SoftView uses the existing chest X-ray to produce the soft tissue image, it eliminates additional dose and motion artifacts commonly associated with dual energy solutions.

Siemens is offering SoftView from Riverain Medical with Ysio, their latest digital radiography system. SoftView can also be acquired as an upgrade for other digital radiography systems from Siemens. The software can easily be integrated and requires no adaptation of the clinical protocols for chest X-rays.

The products mentioned here are not commercially available in all countries. Due to regulatory reasons the future availability in any country cannot be guaranteed. Further details are available from the local Siemens organisations.
