Single-port laparoscope sheath pipe assembly

Abstract

The invention claims a single-port laparoscope sheath pipe assembly, comprising a flexible protection sleeve and a surgical instrument introduced conduit, wherein the flexible protection sleeve comprises a plurality of flexible channels, an airbag in the protection sleeve, a fixing ring in vitro, an elastic corrugated retraction pipe and a fixing ring in vivo; the lower end of the flexible protection sleeve comprises the fixing ring in vitro, the elastic corrugated retraction pipe and the fixing ring in vivo, which are integrally connected from top to bottom; each of a plurality of the flexible channels at the upper end of the flexible protection sleeve is provided with an air check valve; the conduit is inserted into a plurality of the flexible channels and penetrates through the centers of the fixing ring in vitro, the waved elastic retraction pipe and the fixing ring in vivo; an elastic corrugated device connects the plurality of the flexible channels with an exterior ring of the flexible protection sleeve; the conduit is composed of a dual gas check value and an instrument guide pipe; and the dual gas check value is installed above the channel of the instrument guide pipe. In the invention, the flexibility of the surgical instrument operation is increased; and the dual gas check value employs a dual-sealing structure to guarantee the sealing of a guiding channel before and after insertion of the instrument.

Description

technical field [0001] The invention relates to a novel single-hole laparoscopic sheath tube design and component assembly, belonging to the technical field of medical devices. Background technique [0002] With the further development of minimally invasive surgery, abdominal wall scarless surgery has become a new research hotspot, mainly in two aspects: natural orifice endoscopic surgery (NOTES) and transumbilical endoscopic surgery (TUES). [0003] The basic idea of ​​NOTES is to complete intra-abdominal surgery through the natural orifice of the human body, such as the mouth, vagina, anus or urethra, with the help of an endoscopic platform. At present, it is believed that several problems need to be solved before the clinical application of NOTES: firstly, the choice of natural orifice approach is confusing and difficult to close; secondly, the limitation of the operating platform and the single equipment; thirdly, the contrast of spatial positioning and the fixed pattern...

AI Technical Summary

Problems solved by technology

At present, it is believed that several problems need to be solved before the clinical application of NOTES: firstly, the choice of natural orifice approach is confusing and difficult to close; secondly, the limitation of the operating platform and the single equipment; thirdly, the contrast of spatial positioning and the fixed pattern of operating habits. These are the difficulties that NOTES is currently difficult to overcome

The problem is that the incision is not sufficiently retracted and the operation complexity is increased, which makes it difficult to insert and replace surgical instruments and easily damages the sheath

However, there are many deficiencies in the application of existing surgical retractors, mainly due to poor sealing, which cannot expand the necessary surgical space, which affects the field of view and operation
