The development of radiotherapy equipment technology has led to clinical advancement. Major equipment manufacturers include Varian Medical Systems, Medical Medical, and ACCURAY. The latest technologies and progress of these three radiotherapy systems will be introduced below.

Varian's new technology progress

In the Varian Radiation Therapy Solution, the RapidPlan Automated Therapy Design System was introduced. RapidPlan is an automated design tool based on empirical knowledge, using standard treatment plan design templates, and its database is derived from top-level oncology centers. The system's self-performing “learning” and training can improve the quality and consistency of program design, significantly reduce planning time, standardize the treatment planning process, and automatically optimize and provide multiple treatment options. At present, domestic Beijing Cancer Hospital and Fudan Cancer Hospital have carried out clinical tests.

Varian's new True Beam and EDGE radiosurgery integrated solution is a surgical system that enables non-invasive screen "surgery" without the need for third-party products. Both True Beam and EDGE can be used for radiation therapy in all parts of the body. Its advantages are reflected in the rapid sharpening of the edge dose drop, the sub-millimeter clinical accuracy and advanced imaging technology, and equipped with robot bed placement technology and real-time tumor tracking technology.

Based on a deep understanding and thinking of the development trend of radiosurgery, Varian Medical System has launched a new targeted radiosurgery system for the market. It is a comprehensive integration and innovation of current clinical radiosurgery technology, and is the pinnacle of radiosurgery system. The Targeted Positioning System integrates Calypso radiosurgery navigation system, robotic kV-level target tracking imaging technology, 3D/4D CBCT technology, large-scale high-speed dynamic EPID imaging technology and respiratory gating technology to provide complete clinical requirements. Targeted four-dimensional image guidance and target tracking in treatment.

Specially equipped with a cone-shaped light-limiting tube for SRS treatment of small lesions, high-resolution MLC system (2.5mm blade width) for SRS and SBRT, fully automatic control of six-degree-of-freedom treatment bed for precise positioning. The intelligent control system (Maestro) automatically implements accurate beam engraving projections around the lesion under the guidance of its sharp viewing angle, while its physically steep dose drop characteristics give better protection to surrounding normal tissue. Ultra-high dose rate (1400~2400MU/min) and ultra-fast control system response speed (10ms).

Through the original RapidArc volume-modulated illumination technology, the scalpel-like high-dose high-energy beam instantly delivers tumor-damaging ablation. Under the precise guidance of the kV image target real-time tracking or Calypso radiosurgery navigation system, the beam is dynamically manipulated for respiratory-gated spot-directed illumination, or the multi-leaf collimator is used to follow the tumor to provide tracking illumination to achieve accurate target Strike.

About RapidArc

Calypso Radiation Surgery Navigation System - a tool for targeted tracking of motor tumors: GPS electromagnetic beacons (3) that are specifically recognized by individuals are directly implanted into the tumor, and tumor movement is continuously monitored during the treatment. When the amplitude of motion exceeds the preset error limit, the beam can be automatically cut off to ensure the safety of treatment. The use of electromagnetic technology rather than ray tracing avoids secondary damage to the patient. GPS beacons are CT/MR compatible and do not affect CT analog positioning and MR scanning after implantation. The PortalDosimetry airborne quality control system can more effectively escort complex treatment technologies. With the support of the onboard system, QA work can be completed within 5 minutes, making complex treatment techniques more accessible to everyday clinical practice.

Single Use Trocar Site Closure Device

A fascial closure device is a laparoscopic instrument used to close the fascia, the layer of tissue that covers and separates abdominal organs and muscles. The device is used during laparoscopic surgery to create a secure closure of the fascia after the surgical procedure is complete.

The fascial closure device consists of a needle and suture material attached to a handle. A needle is used to puncture the fascia, then suture material is passed through the puncture site and tied tightly to close the fascia. The device's handle is used to control the movement of the needle and suture material, allowing precise placement and closure of the fascia.

The use of fascial closure devices during laparoscopic surgery can help reduce the risk of postoperative complications such as hernias, wound infections, and intestinal obstruction. It also closes the fascia more quickly and efficiently, reducing the overall time required for the procedure.
