Specimen take-out device under laparoscope

Abstract

The invention provides a specimen take-out device under a laparoscope, mainly relating to the field of medical apparatus and instruments. The specimen take-out device under the laparoscope comprises amain rod, wherein a first through hole and a second through hole are arranged in the main rod, a first blade is fixedly arranged at one end of the main rod, a second blade is hinged to the first blade, a first rotation ring is arranged at the hinged point of the second blade, a first handle is arranged at one end, far away from the first blade, of the main rod, a second handle is hinged to the first handle, a second rotation ring is arranged at the hinged point of the second blade, a stretching rod is arranged in the second through hole, an elastic ring is arranged at one end, close to the first blade, of the stretching rod, a storage bag is arranged on the elastic ring, and a grabbing handle is arranged at one end, close to the first handle, of the stretching rod. The specimen take-out device under the laparoscope has the beneficial effects that the specimen take-out device well accords with the ergonomics principle, the matching between a specimen take-out bag and minimally invasivesurgical scissors is good, the surgery time can be effectively shortened, and the success rate of the minimally invasive surgery is improved.

Description

technical field [0001] The invention mainly relates to the field of medical instruments, in particular to a laparoscopic sample taking device. Background technique [0002] Minimally invasive surgery refers to a new technology that performs surgery in the human body through laparoscopy, thoracoscopic and other endoscopes. Minimally invasive surgery has the advantages of less trauma, less pain and faster recovery. In minimally invasive surgery, doctors use special surgical scissors to resect or sample patient tissues under the guidance of laparoscopy or thoracoscopy. Surgical gloves, syringe packaging bags, etc. are temporarily made. During the operation, special surgical scissors for minimally invasive surgery are used to cut off the sample to be removed, and the temporarily made sample removal bag is used to pick it up. This method of sample removal has the following problems: [0003] 1. The temporary specimen retrieval bag is not easy to open in the abdominal cavity, and...

AI Technical Summary

Problems solved by technology

[0003] 1. The temporary specimen retrieval bag is not easy to open in the abdominal cavity, and the specimen is not easy to put into the specimen retrieval bag, which is difficult to operate, and the temporary specimen retrieval bag is not tightly sealed after loading the specimen, which may easily cause the specimen to fall Contamination of the abdominal cavity and other issues

[0004] 2. The handle of the existing special surgical scissors for minimally invasive surgery is rotated by the thumb during operation, which does not conform to ergonomics and is easy to cause the scissors to shake during operation, and may be scratched when cooperating with the specimen removal bag. Break the specimen removal bag, or cause damage to the patient's abdominal cavity

[0005] 3. Using the special surgical scissors for minimally invasive surgery and the specimen removal bag to cooperate with the operation, it is necessary to open two incisions for the surgical scissors and the specimen removal bag wound on the patient's abdomen, which increases the pain of the patient and the risk of surgery
