Self-demisting and decontaminating thoracoscope for thoracic surgery department

Abstract

The invention discloses a self-demisting and decontaminating thoracoscope for a thoracic surgery department. The thoracoscope comprises an inner pipeline, an end cover is fixedly connected to the lower end of the inner pipeline, the end cover is in a semi-spherical shape, the side wall of the inner pipeline is fixedly connected with an outer pipeline through a fixing ring, and the inner wall of the inner pipeline is fixedly connected with the side wall of the outer pipeline through a thermo-electric power generation plate. A plurality of positive wires and negative wires are uniformly embedded in the lower end of the end cover, the positive wires and the negative wires are in coupling connection with the positive electrode and the negative electrode of the thermo-electric power generation plate respectively, and an annular groove is formed in the lower end of the fixing ring. Power is supplied to the positive wire and the negative wire through current on the thermo-electric power generation plate, no current exists in the positive wire and the negative wire, when fog is formed on the outer side of the end cover due to temperature difference and condensed into water drops, the adjacent positive wire and negative wire are communicated through the water drops at the moment, so that the water drops on the end cover are heated, evaporated and rapidly disappear, therefore, a good demisting effect is achieved, and clear shooting of the camera is prevented from being affected by water mist on the end cover.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a self-defogging and decontaminating thoracoscope for thoracic surgery. Background technique [0002] Thoracic surgery is specialized in the study of internal thoracic organs, mainly referring to the diagnosis and treatment of esophagus, lung, and mediastinal lesions. At present, when it is necessary to perform surgery on internal thoracic organs, a thoracoscope needs to be inserted into the thoracic cavity to provide feedback on the internal conditions of the thoracic cavity. , the doctor then makes a hole in another location based on the captured field of view, and then inserts surgical instruments to perform the operation. [0003] Generally speaking, the temperature inside the human body will be higher than the temperature outside the human body. After the thoracoscope is inserted into the body, there will be a significant temperature difference on the end cap of th...

Problems solved by technology

[0003] Generally speaking, the temperature inside the human body will be higher than the temperature outside the human body. After the thoracoscope is inserted into the body, there will be a significant temperature difference on the end cap of the thoracoscope, and then water mist will condense on the end cap, making the camera inside the thoracoscope It is impossible to take a clear picture, which affects the progress of the operation. Therefore, it is necessary to take out the thoracoscope, wipe off the water mist on the end cap, and then shoot. The operation is cumbersome, and it is inevitable that the end cap will It will be splashed with blood stains, which will further affect the clear shooting of the camera
