Embodiment 1

[0033] Please refer to the attached figure 1 , with figure 1 It is a flushing and drying device for a cavity mirror lens in the present invention, including a flushing nozzle 1, a drying nozzle 2, a flushing pipe 3, a drying pipe 4, a flushing liquid connection device 5, a pressure gas connection device 6, a flushing switch 7, a drying spray switch 8, Pressure pump 9, endoscopic lens 10, endoscopic barrel 11, endoscopic handle 12;

[0034] The rinsing nozzle 1 and the drying nozzle 2 protrude within 1 mm of the inclined surface of the cavity mirror lens 10, and the openings of the water nozzle and the air nozzle formed by the rinsing nozzle 1 and the drying nozzle 2 are small inside and large outside; Both the flushing pipe 3 and the drying pipe 4 are hard pipes, which run through the lens barrel 11 of the endoscope and the handle 12 of the endoscope, and the parts passing through the handle 12 of the endoscope are respectively connected with the pressure pump 9; External co...

Embodiment 2

[0037] Please refer to the attached image 3 , with image 3 It is an enlarged schematic diagram of the lens part of another washing and drying device for the lens of the laparoscopic lens of the present invention. This embodiment is basically the same as Embodiment 1, except that the water jets and air jets of the flushing nozzle 1 and the drying nozzle 2 face the lens plane at an angle of about 30°, which can clean the lens more effectively. Reduces time spent cleaning lenses, which in turn shortens surgery time.

[0038] The washing and drying device of the laparoscopic lens of the present invention utilizes the integrated structure design of the laparoscope and the washing and drying device, which facilitates the preparatory work before the operation. Extra pressure on the intercostal nerves and blood vessels in the thoracic cavity, thereby reducing the damage to the human body; use the combined use of the flushing nozzle and the drying nozzle to spray sterile physiologi...

Abstract

The invention relates to an endoscope lens flushing and drying device which comprises a flushing sprayer, a drying sprayer, a flushing pipe, a drying pipe, a flushing fluid connecting device, a pressure gas connecting device, a flushing switch, a drying spray switch, a pressure pump, an endoscope lens, an endoscope lens cone and an endoscope handle. The flushing sprayer and the drying sprayer project over the inclined surface of the endoscope lens cone, the flushing pipe and the drying pipe penetrate the endoscope lens cone and the endoscope handle, the pressure pump is externally connected with the flushing fluid connecting device and the pressure gas connecting device, and the flushing switch and the drying spray switch are positioned on the endoscope handle. The endoscope lens flushingand drying device has the advantages that the lens can be directly flushed and dried in a body cavity without being moved instead of being drawn out, wiped and then placed into the body cavity again when the lens is fuzzy in a surgical process, surgical operation is greatly facilitated, unnecessary time waste is reduced, and surgical risk is further reduced based on safety.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a washing and drying device for a laparoscopic lens. Background technique [0002] Thoracoscopic surgery is a hard instrument with a miniature camera and a cold light source. It is widely used in various types of thoracoscopic lung resection and other operations. Compared with traditional open surgery, it has obvious advantages of small wounds, fast recovery and fewer complications. Advantage. In thoracoscopic surgery, an endoscopic lens with a diameter of about 10mm is inserted into the chest cavity through the intercostal incision, and a cold light source is used for illumination. Using digital camera technology, the images captured by the endoscopic camera are transmitted through optical fibers and processed by the background system. The final image signal is displayed on the external monitor. Doctors analyze and judge the anatomy and condition in the surgical fi...
