Sealing device for minimally invasive disposable puncture device

Abstract

The invention discloses a sealing device for a minimally invasive disposable puncture device, and relates to the sealing device matched with the minimally invasive disposable puncture device for use. The sealing device is a surgical instrument which is matched with minimally invasive endoscopy and suitable for laparoscopy and establishment of abdominal cavity operation working channels in the surgery process. The sealing device comprises a locking and fixing cover, an elastic sealing ring assembly, a compaction ring and a positioning guide cover; the upper end of the locking and fixing cover is provided with an installation platform which is provided with a plurality of positioning pillars; the elastic sealing ring assembly comprises an elastic sealing ring, elastic cloth, an upper fixing ring and a lower fixing ring; the elastic cloth is adhered to two sides of the elastic sealing ring; the upper fixing ring is fixed with lower fixing ring installation holes; the lower fixing ring is provided with sealing ring positioning protruded pillars; the upper fixing ring and the lower fixing ring are arranged on two sides of the elastic sealing ring to which the elastic cloth is adhered respectively; the elastic sealing ring assembly is arranged on the installation platform at the upper end of the locking and fixing cover; and the positioning guide cover is fixed on the upper part of the compaction ring through welding.

Description

technical field [0001] The sealing device of the minimally invasive disposable puncture device of the present invention relates to a sealing device used in conjunction with a minimally invasive disposable puncture device. For working channels. technical background [0002] The front end of the puncture cone of the current disposable puncture device uses a relatively sharp blade, which is easy to scratch other tissues in the interior, causing bleeding and causing unnecessary pain to the patient. Leak out, so that abdominal cavity subsidence affect the normal operation of laparoscopic surgery. [0003] At present, the elastic sealing cap of the disposable puncture device is made of silicone rubber. When the surgical puncture operation is performed, the tubular puncture cone and the olecranon puncture knife cone arranged at the front end will easily puncture the elastic sealing cap and cause abdominal leakage. Gas, the operation cannot proceed normally. Contents of the inve...

Problems solved by technology

[0002] The front end of the puncture cone of the current disposable puncture device uses a relatively sharp blade, which is easy to scratch other tissues in the interior, causing bleeding and causing unnecessary pain to the patient. Leak out, causing the abdominal cavity to sink and affect the normal operation of laparoscopic surgery

[0003] At present, the elastic sealing cap of the disposable puncture device is made of silicone rubber. When the surgical puncture operation is performed, the tubular puncture cone and the olecranon puncture knife cone arranged at the front end will easily puncture the elastic sealing cap and cause abdominal leakage. gas, the operation cannot proceed normally
