Device for cutting and collecting in-vitro bulk tissue under endoscope

Abstract

The invention discloses an in-vitro bulk tissue segmentation and collection device under an endoscope, and belongs to the field of surgical instruments, the device comprises a telescopic baffle, a hollow pipeline, a handle, a driving component, a negative pressure component and a collection box, the telescopic baffle is arranged at the front end of the hollow pipeline, the collection box is detachably arranged at the tail end of the hollow pipeline, the handle is arranged on one side of the hollow pipeline, and the driving component is arranged on the other side of the hollow pipeline. The driving component and the negative pressure component are arranged in the handle, the driving component is connected with the telescopic baffle, a cutting blade is arranged at the front end of the hollow pipeline, and the air suction end of the negative pressure component is communicated with the collecting box. The telescopic baffle is driven by the driving component to be attached to the cutting blade, large tissue blocks are rapidly cut into small cylindrical blocks, meanwhile, the small tissue blocks can be collected into the collecting box in a centralized mode after passing through the hollow pipeline, collection is convenient, through the cutting mode that the telescopic baffle is attached to the cutting blade, wounds of a patient are not obviously increased, the operation time can be shortened, and the operation efficiency is improved. And the increased infection probability caused by wound enlargement is avoided.

Description

technical field [0001] The invention relates to the field of surgical instruments, in particular to a device for dividing and collecting large pieces of tissue in vitro under a laparoscope. Background technique [0002] Compared with traditional surgery, laparoscopic surgery has the advantages of smaller incision and faster recovery, and its advantages are more and more prominent in surgical applications. However, the removal of large tissue (benign lesions) in vitro through small incisions is often time-consuming and laborious, and even increases the risk of trauma to patients If the tissue is taken out by expanding the incision, the advantage of the small incision of the endoscopic surgery is weakened, which will not only significantly increase the trauma of the patient, but also cause the increased infection probability due to the enlarged wound. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a device for dividing and collecting bul...

[0002] Compared with traditional surgery, laparoscopic surgery has the advantages of smaller incision and faster recovery, and its advantages are becoming more and more prominent in surgical applications. However, it is time-consuming and laborious to remove large tissue (benign lesions) from the body through small incisions, and even increases the risk of trauma for patients. If the tissue is taken out through an enlarged incision, the advantage of small incision in laparoscopic surgery will be weakened, which will not only significantly increase the trauma of the patient, but also increase the chance of infection due to the enlarged wound
