Inflatable double-opened-blade protection type puncturing device for thoracoscope

Abstract

The invention discloses an inflatable double-opened-blade protection type puncturing device for a thoracoscope. The inflatable double-opened-blade protection type puncturing device comprises a hollow tube pipe; a pair of clamping arms rotating around a fixed shaft and an airbag mechanism for driving the clamping arms to clamp a thoracoscope lens are arranged at the end part of the hollow pipe body; each clamping arm consists of a long movable blade and a short movable blade; air cavity bags are arranged on the inner lateral faces of the long movable blades and the short movable blades and the surface of the end part of the hollow pipe body; and when the air cavity bags are full of gas, the long movable blades and the short movable blades rotate around the fixing shaft to an expansion state until the long movable blades and the short movable blades are compactly connected with the thoracoscope lens at the bottom of the hollow pipe body. The double-opened movable blades lead bloods at a cut position well, so that the pollution on the thoracoscope lens can be reduced. The airbags at the end parts of the hollow pipe body are prevented from being damaged on intercostals nervus vascularis and the like through the design; and meanwhile, the inflatable double-opened-blade protection type puncturing device has certain effects of hemostasis by compression on the cut. Furthermore, the airbags at the inner sides of the double-opened movable blades form a protection cushion to buffer the upper turning shape of the thoracoscope lens. Therefore, the inner side of the chest wall can be prevented from being damaged.

Description

technical field [0001] The invention relates to a medical device, in particular to an inflatable double-leaf protective thoracoscopic trocar. Background technique [0002] The trocar (Trocar) is a necessary auxiliary surgical instrument in laparoscopic surgery. It helps the laparoscope not to be polluted when it enters and exits the incision, and reduces the incision damage caused by the lens repeatedly entering and exiting the incision. [0003] However, the Trocars used in the existing thoracoscopic surgery are all laparoscopic Trocars, so that there is a large damage to the intercostal blood vessels and nerves. In addition, the existing Trocars all have the problem that once the incision bleeds, the blood will stay along the Trocar wall. Pollution of the lens down will slow down the operation process; at the same time, when the distal end or close to the chest wall is observed during the operation, the endoscope is upwardly warped and compresses the chest wall tissue (esp...

Problems solved by technology

[0003] However, the Trocars used in the existing thoracoscopic surgery are all laparoscopic Trocars, so that there is a large damage to the intercostal blood vessels and nerves. In addition, the existing Trocars all have the problem that once the incision bleeds, the blood will stay along the Trocar wall. Pollution of the lens down will slow down the operation process; at the same time, when the distal end or close to the chest wall is observed during the operation, the endoscope is upwardly warped and compresses the chest wall tissue (especially when using a 0-degree endoscope), resulting in damage or bleeding that is difficult to observe and handle during the operation , leading to increased risks of secondary surgery and postoperative pain
