Disposable puncture device

Abstract

The invention relates to a disposable puncture device and relates to surgical instruments matched with endoscopes outside the breast and the abdomen. The disposable puncture device is a surgical instrument which is applied to thoracic cavity and enterocoelia endoscope detection and establishing of a thoracic cavity operation working channel and an enterocoelia operation working channel in an operation process. The disposable puncture device comprises a puncture device body device, a gas-tight sealing device, a locking device and a puncture cone device. The puncture device body device comprises a puncture device body, a gas exhausting pipe, a gas exhausting core, a gas intake valve, an arc sealing seat, a gas-tight sealing hood, a puncture cone guiding hood, a moving bolt cover and a gas-tight moving bolt. The gas-tight sealing device comprises a gas-tight sealing sleeve, a supporting ring, a sealing ring, a pressing sheet and a security sealing sheet. The locking device comprises a locking ring, a cannula, a protection ring, a locking gasket, a locking hood, a tightening wheel, a locking ring and a locking wrench. The puncture cone device comprises a cross cone, a puncture rod, a puncture rod seat and a puncture positioning nut. The puncture cone device is inserted into the puncture device body by going through the puncture cone guiding hood, the gas-tight sealing hood and the sealing device.

Description

technical field [0001] The disposable puncture device of the present invention relates to a surgical instrument for thoracic cavity and external laparoscopy, which is suitable for thoracic cavity and laparoscopic examination and for establishing thoracic cavity and abdominal cavity operation channels during operation. Background technique [0002] The front end of the puncture cone of the current disposable puncture device has a relatively sharp blade, which is easy to scratch other tissues of the internal organs, causing bleeding and unnecessary pain for the patient. In addition, the current puncture device is prone to air leakage during the operation and the gas input into the abdominal cavity will leak out. The subsidence of the abdominal cavity affects the normal operation of laparoscopic surgery. At the same time, ordinary trocars are inserted into the abdominal cavity and chest cavity, which is not very stable. The trocar is prone to loosening and easily affects the ...

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 and other tissues, causing bleeding and unnecessary pain for the patient. In addition, the current puncture device surgery It is easy to leak air during the process, and the gas input into the abdominal cavity will leak out, causing the abdominal cavity to sink and affecting the normal operation of laparoscopic surgery

At the same time, the ordinary puncture device is inserted into the abdominal cavity and chest cavity, which is not very stable. The puncture device is prone to loosening and easily affects the operation. The endoscope uses the puncture device to check that the front end of the endoscope body will touch the internal tissue and affect the inspection effect.
