Minimal-invasion surgical fetching system capable of smashing specimen by pneumoperitoneum

Abstract

The invention relates to the technical field of medical apparatus, in particular to a minimal-invasion surgical fetching system capable of smashing a specimen by pneumoperitoneum, and the system can take out an internal bulk-mass-lesion excised tissue during a surgery. The system includes a fetching bag device, the fetching bag device includes a bag body, a bag opening of the bag body is provided with an extendable ring, and the system further includes a sealing cover matched with the extendable ring, an air-inflation device for inflating the bag body and a smashing device for smashing pathological tissues. An air inflation channel for the air inflation device and a smashing channel for the smashing device are arranged on the sealing cover, air seal is conducted between the air inflation channel and the air inflation device, and the air seal is conducted between the smashing channel and the smashing device. The fetching system capable of conducting rotary cutting on foreign matters by pneumoperitoneum can take out bulk-mass pathological tissues from smaller incisions, and internal residual pathological tissues are avoided. The fetching system is safe and reliable, and reduces the risk of disease relapse of patients.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a system capable of removing large-volume diseased tissues in the body during surgery. Background technique [0002] In surgery, especially in minimally invasive surgery, it is often necessary to remove the resected diseased tissue from the incision. The method of removal is generally to remove the diseased tissue and put it into the retrieval bag, and then take out the retrieval bag together with the diseased tissue , there are many patents related to the retrieval bag, such as the application number 201410643242.2, which is called the patent of the disposable retrieval bag for minimally invasive surgery, which discloses a retrieval bag composed of a sleeve, a push rod and an opening bag. The diseased tissue is removed and placed in a bag, which is then removed through the incision. But the shortcoming of above-mentioned prior art is, when the diseased tissue that cuts ...

AI Technical Summary

Problems solved by technology

But the shortcoming of above-mentioned prior art is, when the diseased tissue that cuts off is bigger, can't take out from incision, the solution has two, and one is to enlarge incision, but this will bring greater misery to the patient, Another way to prolong the recovery period is to chop up the diseased tissue and put it into the retrieval bag to take it out, but this method is likely to leave diseased tissue in the patient's body, increasing the chance of disease recurrence
