Thoracic cavity opening device for cardiothoracic surgery department

Abstract

The invention discloses a thoracic cavity opening device for the cardiothoracic surgery department, and particularly relates to the field of the cardiothoracic surgery department. The device comprises a base plate, supporting columns are arranged on the two sides of the base plate, a mounting rod is arranged at the top ends of the supporting columns, a fixing ring is arranged at one end of the mounting rod, and a positioning ring is arranged at the bottom end of the fixing ring. By arranging the fixing ring, the positioning ring and a limiting rod, before use, after the operation position and direction are determined, the fixing ring is pulled back and forth along the mounting rod, so that the transverse position of the positioning ring is adjusted till the positioning ring moves to the position over the operation position, and after positioning is completed, plug pins are inserted into the corresponding first limiting holes downwards to fix an inner tube, when the direction of the positioning ring is adjusted, the positioning ring rotates along the fixing ring to adjust the direction until the pulling direction of the opening structure is perpendicular to the direction of a surgical incision, the position of the positioning ring can be adjusted at any time according to different conditions, and the device is practical.

Description

technical field [0001] The embodiments of the present invention relate to the field of thoracic and cardiothoracic surgery, and in particular to a thoracic cavity expansion device for thoracic and cardiothoracic surgery. Background technique [0002] Cardiothoracic surgery requires the patient's chest to be opened for surgery. In the past, the chest was in a state of continuous contraction due to the need for physiological breathing of the patient, which affected medical staff's surgical operations. [0003] There are following deficiencies in the prior art: when using the existing thoracic cavity expansion device, it is necessary to determine the specific position of the operation and the direction of the surgical incision, and then install it. After the installation, the position of the expansion mechanism cannot be adjusted. Adjustment has certain limitations in use. Contents of the invention [0004] To this end, the embodiment of the present invention provides a thor...

Problems solved by technology

[0004] To this end, the embodiment of the present invention provides a thoracic cavity expansion device for thoracic surgery. Through the fixing ring, the positioning ring and the limit rod, before use, after the operation position and direction are determined, the fixing ring is pulled back and forth along the installation rod, In this way, adjust the lateral position of the positioning ring until the positioning ring moves directly above the operation position. After the positioning is completed, insert the pin down into the corresponding first limiting hole to fix the inner tube, and then adjust the direction of the positioning ring. At the same time, the positioning ring is rotated along the fixed ring to adjust the direction until the pulling direction of the stretching structure is perpendicular to the direction of the surgical incision, and the position of the positioning ring can be adjusted at any time according to different situations, which is more practical and solves the problem of the prior art. The problem caused by the difficulty in adjusting the strut structure
