Analysis of 70 laparoscopic surgery patients
Multi-joint instruments are better than fixed types.
Reduce surgery time by 34 minutes
Reduces bleeding by half
Seoul National University Bundang Hospital (Director Song Jeong-han) announced that ‘multi-joint instruments’ can reduce surgery time and improve prognosis compared to existing fixed instruments in laparoscopic colon surgery.
According to Seoul National University Bundang Hospital on the 22nd, the surgical team led by Oh Heung-kwon (corresponding author) and Shin Hye-rim (first author) demonstrated that multi-joint instruments increase the efficiency of the surgical process and improve prognosis compared to existing fixed instruments in laparoscopic colon surgery. did it
Laparoscopic surgery of the large intestine is highly difficult because it requires performing various manipulations with surgical instruments in a narrow space inside the body. It was pointed out that existing fixed instruments only move in a single direction, making it difficult to secure the operator’s field of view and perform precise processing.
Multi-joint instruments were introduced to improve efficiency and accuracy in the surgical process. This device is known to have a multi-joint design that mimics the movements of a person’s wrist and allows manipulation in multiple directions, providing freedom of movement even in narrow spaces within the body.

The Seoul National University Bundang Hospital research team began work to determine how much multi-joint laparoscopic instruments could improve surgical effectiveness and safety compared to existing fixed instruments.
First, 70 patients requiring laparoscopic surgery for colon cancer, etc. were selected. Afterwards, they were divided into a group using fixed instruments (20 people) and a group using multi-joint instruments (50 people) and the surgical outcomes were analyzed.
This evaluation was conducted by analyzing surgical videos and using ‘mGOALS’, a global laparoscopic surgery technology evaluation tool.
mGOALS is an index that evaluates four key areas, including the operator’s depth perception, two-hand technique, efficiency, and tissue processing, and provides systematic and objective information on surgical performance. In addition, surgery time, bleeding amount, hospitalization period, and postoperative complication rate were additionally analyzed.
According to the research team, when using a multi-joint instrument, the surgery time was shortened by about 34 minutes compared to the existing fixed type. The amount of bleeding during surgery was reduced by about half. The operator’s ability to handle tissue and recognize depth also showed significant improvement in the group using multi-joint instruments compared to the fixed instrument.
This means that multi-joint laparoscopic instruments can improve surgical performance by increasing operator operability and enabling accurate vision and precise manipulation during surgery.
Additionally, it was confirmed that the surgical performance continued to improve as the medical staff gained proficiency in using the instruments. According to the research team, sufficient proficiency can be achieved by using the multi-joint device about 10 times.
The results of this study are the first to verify the effectiveness and safety of a multi-joint instrument in laparoscopic colon surgery. It is significant to discover the possibility that a multi-joint instrument can increase the efficiency of colon surgery and have a positive effect on the patient’s recovery speed.
Professor Oh said, “Multi-joint laparoscopic surgical instruments are more economical than robotic surgery and provide similar level of multi-directional manipulation functions, so we expect them to be widely used in various medical settings in the future,” adding, “We have verified the effectiveness of multi-joint laparoscopic instruments in other complex surgeries.” “We plan to secure more clinical evidence by conducting as much research as possible,” he said.
This study was supported by the Korea Health Industry Development Institute’s Innovative Medical Device Demonstration Support Project and was published in the Journal of the European Society of Colorectal Surgery last month.
**Considering the study’s findings regarding surgery time, bleeding, and patient recovery, what are the potential long-term implications of using multi-joint instruments on overall patient outcomes and quality of life after colon surgery?**
