A negative pressure suction device for thoracoscopic surgery

Abstract

A negative pressure suction device for thoracoscopic surgery, comprising a negative pressure suction device for thoracoscopic surgery, a video optical fiber cable, a miniature optical fiber camera, a monitoring screen, a switching power supply, and a GPRS module. There are through holes in the middle, and the video optical fiber cable is sheathed in three through holes, two of which are located at the upper right end of one side of the suction head and the front side of the through hole in the middle right, and there are pull ropes on the left and right sides of the through hole in the middle of the handle shell. Through hole, the third camera is sleeved in the ferrule, the front and rear ends of the ferrule are respectively connected with one end of the two pull ropes, the middle part of the connecting rod on the rear side of the ferrule is hingedly installed on the rear side of the upper left part of the adsorption head; the lower part of the handle shell There are two shaft holes on the front side, and the rear shaft rods of the two gears are located in the two shaft holes respectively. rear end of the shaft. The invention absorbs the body fluid of the patient, and can provide 360-degree video information without dead angle for the surgeon.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a negative pressure suction device for thoracoscopic surgery. Background technique [0002] Thoracoscopic surgery (TV-assisted thoracoscopic surgery) is a surgical instrument and equipment that combines modern camera technology and high-tech technical means. The essence of thoracoscopic surgery is the same as the principle of open surgery, but the traditional surgical approach, separation steps, ligation and suture methods, and observation methods during the operation (from direct naked eye observation to endoscopic observation) have been changed. The surgeon completes complex intrathoracic surgery under the chest wall cannula or tiny incision. Compared with traditional open surgery, it has the technical characteristics of less trauma, faster recovery, and shorter hospital stay. Surgical operation brings great convenience, so it is more and more widely used in clinical medicine....

Problems solved by technology

[0004] In order to overcome the limitations of the structure of the existing negative pressure suction device for thoracic surgery, the inconvenience for the surgeon to operate, and the disadvantages of causing the patient's body to be injured by the suction head, the present invention provides a main body of the negative pressure suction device for thoracoscopic surgery. Multiple miniature fiber optic cameras are added on the basis of the above-mentioned technology. Multiple miniature fiber optic cameras are connected by fiber optic cables and fiber optic monitoring screens. One of the cameras can be easily adjusted during use, which is beneficial for the surgeon to effectively control the internal conditions of the patient. The body of the miniature optical fiber camera probe, optical fiber cable and thoracoscopic surgery negative pressure suction device is compact and effectively combined, which facilitates the operation of the surgeon. The position of the suction head in the patient's body can effectively absorb the tissue fluid in the patient's body, and reduce the chance of the patient's organs being injured, and the video signal can be transmitted to the remote monitoring personnel (such as the superior doctor in charge) in real time during the operation, and then the remote monitoring personnel A negative pressure suction device for thoracoscopic surgery that can monitor the operation process in real time
