Disposable laparoscopic soft instrument sheath device

Abstract

The invention discloses a disposable laparoscopic soft instrument sheath device which relates to an endoscopic matching surgical instrument, which is used for gynecological pneumoperitoneum-free suspension laparoscopic surgery and small incision surgery, and is used for expanding incision field, protecting incision from injury and reducing incision infection. The device comprises an instrument introduction assembly, an intake and exhaust protector body, a locking mechanism and a cut-in sleeve. An instrument introduction sleeve device in that instrument introduction assembly comprise a fixing ring, an instrument introduction sleeve, a gas-blocking upper seal sleeve, a gas-blocking sleeve, a gas-blocking re, a gas-blocking lower seal sleeve and a connecting seat. The puncture sealing sleevedevice comprises a puncture sealing sleeve, a sealing gasket, a sealing fixing ring, a sealing gasket and a sealing connector. The intake and exhaust protector body comprises an intake valve, an exhaust valve, a connecting bottom pipe and an intake and exhaust ring body. The connecting and locking mechanism comprises a fixed ring body piece, an inner bayonet plate, an outer bayonet plate and a locking buckle. The cutout access sleeve comprises an access sleeve connector, an access sleeve outer ring, an access sleeve passage and an access sleeve insertion ring.

Description

technical field [0001] The disposable laparoscopic soft instrument sheath device of the present invention relates to an endoscope matching surgical instrument, and is used in gynecological pneumoperitoneum suspension laparoscopic surgery and small incision surgery to expand the incision field, protect the The incision is protected from injury and reduces incision infection. Background technique [0002] The current disposable protective cover often cannot absorb the smoke generated in the operation, which affects the vision. Also can not inject gas to provide good operation environment, and sealing is poor, influences operation effect. In addition, the current disposable protective cover can only be used for a single operation channel, and theoretically only one surgical instrument can enter, or multiple surgical instruments enter the abdominal cavity through a single operation channel, and interfere with each other, rub, collide, and affect the operation of the operator. ...

Problems solved by technology

[0002] The current disposable protective cover often cannot absorb the smoke generated during the operation, which affects the vision

It also cannot inject gas to provide a good surgical environment, and the sealing is poor, which affects the surgical effect

In addition, the current disposable protective cover can only be used for a single operation channel, and theoretically only one surgical instrument can enter, or multiple surgical instruments enter the abdominal cavity through a single operation channel, and interfere with each other, rub, collide, and affect the operation of the operator. Increased instrument wear and damage

Although there are multi-channel incision protective sleeves, due to the poor sealing of the channel instrument inlets, it is easy to leak air, resulting in the leakage of gas injected into the abdominal cavity during the operation, and the use safety is not high.

In addition, the connection structure between the incision protective cover and the connection locking mechanism is complicated, and inconvenient use will affect the operation

At present, the incision protective cover is usually made of hose or silicone material, which is not easy to adjust the height and angle
