Abstract

The invention relates to a negative-pressure rotary cut specimen extractor used for laparoscopic surgery. The extractor is characterized by comprising a handle, a specimen collecting chamber and a rotary cut sleeve pipe. One end of the specimen collecting chamber is fixedly provided with the handle, the other end of the specimen collecting chamber is fixedly provided with the rotary cut sleeve pipe, a power motor is installed in the handle, a rotating shaft of the power motor is connected with a rotary cut blade through a connection rod, the rotary cut blade is located in the rotary cut sleevepipe, the power motor is connected with an external power supply through a wire, and the top of the specimen collecting chamber is provided with a negative-pressure device connection opening. The extractor is scientific and reasonable in design, a large-size specimen can be smoothly taken out, after the specimen is orderly taken out from the body, the original structure of the specimen still canbe restored, and the follow-up pathological study is facilitated.

Description

technical field [0001] The invention belongs to the field of medical supplies, and relates to a specimen extractor, in particular to a negative pressure rotary cutting specimen extractor for laparoscopic surgery. Background technique [0002] With the rapid development of minimally invasive techniques, laparoscopic surgery is becoming more and more mature, and the indications for laparoscopic surgery are also expanding. Surgical methods for large-volume solid tumors have broken the original forbidden zone, and minimally invasive treatment based on laparoscopy has gradually become the preferred option for larger tumors. However, especially for tumors above 5 cm, after minimally invasive laparoscopic resection, most of them need to extend the incision again to remove the whole piece, which again brings the trauma of large incision to the patient. [0003] At present, the specimen bags routinely used in clinical laparoscopic surgery can play a good sealing role, which can avoi...
