Embodiment Construction

[0030] An endoscopic specimen retrieval system includes a retrieval tool mechanism and a retrieval execution mechanism. The retrieval tool mechanism includes a quick-change connector 1, a quick-change device sleeve 4, a push rod 5, and an outer tube 7. The push rod 5 One end is connected with the quick-change device sleeve 4 and the quick-change connector 1. The outer sleeve 7 is covered with the push rod 5 and the outer side of the quick-change device sleeve 4; the fetching actuator includes a fetching outer tube 20 and a fetching bag 17 And the cross joint 19, the taking bag 17 and the cross joint 19 are set in the taking outer tube 20; the quick change joint 1 of the quick change device sleeve 4 is connected with the cross joint 19 of the taking bag 17, the outer tube 7 and the taking jacket The tube 20 is connected.

[0031] A positioning groove 6 is provided on the outer side of the sleeve 4 of the quick change device, a positioning boss 16 is provided on the outer sleeve 7,...

Abstract

The invention relates to the technical field of medicinal minimally invasive instruments, in particular to a system for taking an endoscope specimen. The system comprises a taking tool mechanism and a taking executing mechanism. The taking tool mechanism comprises a quick-change connector, a quick-change device sleeve, a pushing rod and an outer sleeve. One end of the pushing rod is connected with the quick-change device sleeve and the quick-change connector, and the pushing rod and the outer side of the quick-change device sleeve are arranged inside the outer sleeve in a sleeved mode; the taking executing mechanism comprises a taking outer sleeve, a taking bag and a cross joint, and the taking bag and the cross joint are arranged inside the taking outer sleeve in a sleeved mode; the quick-change connector of the quick-change device sleeve is connected with the cross joint of the taking bag, and the outer sleeve is connected with the taking outer sleeve. The taking tool mechanism can be repeatedly sterilized for usage, so that the using cost of equipment is substantially lowered. Positioning grooves are formed in the outer side of the quick-change device sleeve, and positioning bosses are arranged on the outer sleeve and clamped to the positioning grooves. The outer sleeve is positioned, the pushing rod and the quick-change device sleeve are effectively prevented from axially moving when the system is used, and therefore a doctor can operate conveniently.

Description

Technical field [0001] The invention relates to the technical field of medical minimally invasive instruments, in particular to an endoscopic specimen retrieval system. Background technique [0002] With the development of modern medicine, people have higher and higher requirements for professional technology. Endoscopic surgery is the core technology of minimally invasive surgery. Its appearance has reduced the surgical incision to the extreme, but if the incision is not used and handled correctly, it can turn minimally invasive surgery into a mega-invasive. In the small incision stomatoscope surgery for patients with infectious diseases and tumor patients, in addition to strictly following the principle of “tumor-free operation”, how to quickly and safely remove and remove diseased specimens from the patient’s body? These are whether endoscopic surgery The key to success. In recent years, the use of disposable endoscopic specimen retrieval bags has been widely used in various...
