Disposable puncture outfit sealing device

Abstract

The invention relates to a disposable puncture outfit sealing device. The disposable puncture outfit sealing device is used in cooperation with a disposable puncture outfit, is a minimally invasive endoscope cooperative surgical instrument, and is suitable for establishing surgical working channels in abdominal cavity, urinary and gynecology endoscope inspection and surgery processes. The disposable puncture outfit sealing device comprises a puncture sleeve, an air injection valve, an air injection switch, an air blocking sealing fin, a plane sealing fin and a valve body upper cover. A valve body is arranged at the rear portion of the puncture sleeve and integrated with the puncture sleeve. The air blocking sealing fin is installed in a valve body inner cavity. The plane sealing fin is arranged at the rear portion of the air blocking sealing piece in the valve body inner cavity. A valve body upper cover is installed in a valve body upper cover installing groove of the valve body. The plane sealing piece tightly-pressing step is matched with a valve body upper cover tightly-pressing groove of the plane sealing fin so that the plane sealing fin and the air blocking sealing fin can be tightly pressed.

Description

Technical field [0001] The invention relates to a disposable trocar sealing device. The disposable trocar sealing device is used in conjunction with the disposable trocar. It is a minimally invasive endoscopic surgical instrument suitable for abdominal cavity, urinary, gynecological endoscopy and surgery It is used to establish a working channel during the operation. Background technique [0002] The tip of the puncture cone of the current disposable trocar is relatively sharp, which is easy to scratch other tissues of the internal organs, cause bleeding, and cause unnecessary pain for the patient. In addition, the current trocar is easy to leak during the operation and the gas input into the abdominal cavity leaks Come out, make the abdominal cavity sink and affect the normal operation of laparoscopic surgery. [0003] In addition, the existing disposable trocar (Chinese patent 201010193536.1) has a complicated sealing device structure, difficult parts processing and assembly, hi...

AI Technical Summary

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 internal organs, cause bleeding, and cause unnecessary pain to the patient. In addition, the current puncture device is prone to air leakage during the operation and will leak the gas input into the abdominal cavity. come out, causing the abdominal cavity to sink and affect the normal operation of laparoscopic surgery

[0003] In addition, the existing disposable puncture device (Chinese patent 201010193536.1) has a complex structure of the sealing device, great difficulty in parts processing and assembly, high production cost and high sales price, which increases the financial burden on patients
