Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a laparoscopic blood clot removal device. Background Art

[0002] Currently, patients with abdominal lesions need to use a blood clot removal device during laparoscopic minimally invasive surgery to remove blood clots generated during the operation.

[0003] However, in the prior art, an aspirator is usually used to remove blood clots through the aspiration tube of the aspirator, but only some smaller blood clots can be removed, and some larger blood clots cannot be quickly and conveniently removed. For these larger blood clots, medical staff generally use forceps to clamp them out, but larger blood clots are easily broken when being clamped, resulting in the need for medical staff to repeatedly clean them, which undoubtedly increases the difficulty of operation for medical staff and is likely to delay the patient's condition. For this reason, we propose a laparoscopic blood clot removal device. Utility Model Content
