Description

Technical Field

[0001] The present invention relates to the technical field of tumor resection, and in particular to a laparoscopic minimally invasive tumor resection device. Background Art

[0002] Laparoscopic surgery is a newly developed minimally invasive method and an inevitable trend in the development of surgical methods in the future. With the rapid development of industrial manufacturing technology, the integration of related disciplines has laid a solid foundation for the development of new technologies and methods. Coupled with the increasingly skilled operation of doctors, many open surgeries in the past have now been replaced by endoscopic surgeries, greatly increasing the opportunities for surgical options.

[0003] During minimally invasive surgery for tumor resection under laparoscopy, the surgeon needs to remove the tumor by inserting a knife into the patient's abdominal cavity. Most of the removed tumor masses are transferred to another instrument through the knife, and then removed from the abdominal cavity by another instrument. This takes a long time, and there is also a risk of the tumor mass falling off during the transfer process. If the tumor mass cannot be removed in time, it may increase the difficulty of the operation and further increase the risk of treatment. Therefore, when performing tumor resection surgery, a resection device that can remove the tumor mass in time is needed. Summary of the invention
