Negative pressure aspirator for thoracoscopic surgery

Abstract

The present invention discloses a negative pressure aspirator for thoracoscopic surgery which comprises a thoracoscopic surgery negative pressure aspirator body, a video optical fiber cable, a miniature optical fiber camera, a monitoring screen, a switching power supply and a GPRS module. Through holes are formed in the front end and the middle parts in the left and right ends of an outer shell ofthe aspirator body; the video optical fiber cable is sleeved in the three through holes; the two cameras are located at the upper right end of one side of the adsorption head and in front of the right middle through hole, pull rope through holes are formed in the left side and the right side of the middle through hole of the handle shell respectively, the third camera is sleeved with the ferrule,the front end and the rear end of the ferrule are connected with one ends of the two pull ropes respectively, and the middle of the ferrule rear side connecting rod is hinged to the upper left rear side of the adsorption head. Two shaft holes are formed in the lower front side of the handle shell, shaft rods at the rear ends of the two gears are located in the two shaft holes respectively, a front cover of the handle shell is installed at the front ends of the two gears, and the other ends of the two pull ropes are fixedly installed at the rear side ends of the two gear shaft rods in a winding mode respectively. The device is adsorbed in body fluid of a patient, and 360-degree omnibearingvideo information can be provided for surgeons.

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 that combines modern camera technology and high-tech techniques. The essence of thoracoscopic surgery is the same as that of open surgery, but it changes the traditional surgical approach, separation steps, ligation and suture methods, and the observation method during the operation (from direct naked eye observation to endoscopic observation); during the operation, Surgeons complete complex intrathoracic surgery under the chest wall cannula or tiny incision. Compared with the traditional open surgery, it has the technical characteristics of less trauma, faster recovery, and shorter hospital stay; Surgical operation has brought 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
