Description

Technical Field

[0001] This invention relates to the field of medical technology, and in particular to a device for cleaning and defogging endoscopic lenses. Background Technology

[0002] Thoracoscopic surgery is short for Video-Assisted Thoracic Surgery (VATS). Essentially, it involves performing surgery using a "laparoscopy" (or laparoscopic surgery).

[0003] In actual thoracoscopic surgery, although the bony thoracic cage can provide some space for laparoscopic operation, in the limited space, when using high-energy instruments such as electrocautery, ultrasonic scalpel, and energy platform to separate wounds, sever tissues and blood vessels, oil droplets, blood droplets, water mist and other contaminants will inevitably appear on the laparoscopic lens.

[0004] In addition, blood and smudges flowing down the endoscopic cannula from the incision site of the trocar cause repeated contamination of the endoscopic lens. This necessitates frequent interruptions during the procedure to remove the lens outside the chest cavity for cleaning. After the cleaned lens is placed back into the chest cavity, the temperature difference between the operating room (20-24℃) and the chest cavity (37℃) often causes fogging. This requires repeated wiping or prolonged warming in hot water before re-insertion, a time-consuming process.

[0005] Repeated contamination can significantly prolong surgery time, increase the dosage of anesthetic drugs, and increase the surgeon's energy and physical exertion. Furthermore, it can lead to repeated traction on organs and repetitive surgical procedures due to the need to rearrange the field of vision, which may result in complications such as intraoperative bleeding and injury.

[0006] In summary, there is an urgent need to design a laparoscope lens cleaning and defogging device to overcome the aforementioned technical problems. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a laparoscopic lens cleaning and defogging device.

[0060] To facilitate understanding of the purpose, technical solution, and effects of this invention, the invention will now be further described in detail with reference to the embodiments.

[0061] like Figure 1-7 As shown, the endoscope lens cleaning and defogging device of the present invention includes:

[0062] The base body 1 consists of a heating box 11 and a partition assembly 12 disposed on its outer side wall;

[0063] The cleaning and defogging assembly 2 includes an integrally connected tube body assembly 21 consisting of a cleaning sleeve 211, a connecting hose 213, and a heating tube 212; a liquid storage assembly 22 located at the top of the cleaning sleeve 211; a drain pipe 24 located at the bottom of the cleaning sleeve 211; and a brushing assembly 23; the cleaning and defogging assembly 2 is mounted on the base body 1.

[0064] The control component 4 is located in the bottom receiving groove of the heating box 11, and is electrically connected to the brushing component 23, the electric heating wire 112 in the heating box 11, and the electronic valve 223 located at the liquid storage component 22.

[0065] The endoscope lens cleaning and defogging device of this application embodiment, during use:

[0066] Medical staff will first put a sterile protective cover that meets the usage specifications on the base body 1, and then install the cleaning and demisting component 2 on the base body 1; first, insert the heating tube 212 into the heating box 11 through the through hole 111 on the side wall of the heating box 11, so that the connecting hose 213 is located at the through hole 111; then, clamp the electronic valve 223 onto the liquid outlet tube 222, and connect the brush rod 2312 to the output shaft of the motor 232;

[0067] After assembly, inject an appropriate amount of sterile water into the water storage tank 221. When in use, insert the endoscope lens into the opening end of the cleaning sleeve 211. When the sensor 1 31 senses the insertion of the endoscope lens, it transmits the sensing signal to the microprocessor 43, and the electronic valve 223 opens, allowing sterile water to flow from the water storage tank 221 to moisten the lens. At the same time, the motor 232 starts working, driving the brush head 2311 to start rotating and cleaning the lens. When the sensor 2 32 senses the endoscope lens, the electronic valve 223 closes and the motor 232 stops working. The electric heating wire 112 starts heating, and the lens enters the heating tube 212 until heating ends. The alarm component 46 then activates the alarm operation, and the lens can be removed and pulled out for further use.

[0068] After use, pour out the liquid in the recycling box 13 and replace the cleaning and defogging component 2. The sterile protective cover can be discarded together.

[0069] It should be noted that before using the cleaning and defogging device, a sterile protective cover that meets its usage requirements must be fitted onto the base body 1. Therefore, the sterile protective cover has multiple corresponding openings to ensure that it can be fitted normally without affecting the normal operation of the cleaning and defogging.

[0070] The endoscope lens cleaning and defogging device of this application embodiment has a cleaning and defogging component 2 that is a disposable medical consumable that needs to be replaced after use.

It should be noted that in order to ensure the stability of the device, the heating box 11 has a larger weight on one side, so its stability is good and it will not tip over or cause other problems.

[0077] like Figure 2 As shown, in the endoscope lens cleaning and defogging device of the present invention, the drain pipe 24 passes through the opening 1231 on the support plate 123 and the corresponding drain hole on the bottom plate 122 and is inserted into the recycling hole at the top of the recycling box 13.

[0078] The brush rod 2312 of the brushing assembly 23 passes through the opening 1232 on the support plate 123 and is connected to the output shaft of the motor 232 located at the bottom of the support plate 123.

[0079] In the endoscope lens cleaning and defogging device of this application embodiment, the support plate 123 is used to place the cleaning sleeve 211, so it must be provided with an opening 1231 and an opening 1232 for the drainage pipe 24 and the brush rod 2312 to pass through.

[0080] In the endoscope lens cleaning and defogging device of this application embodiment, one end side wall of the recovery box 13 can be connected to the side wall of the heating box 11 by plugging. In order to facilitate the smooth entry of cleaning fluid into the recovery box 13, an exhaust hole 14 is required on the side wall of the recovery box 13 near the top.

[0088] It should be noted that both sensor 31 and sensor 32 are infrared sensors. Infrared sensors are sensors that use infrared light for data processing and have advantages such as high sensitivity. Infrared sensors can control the operation of the drive device. Those skilled in the art can select appropriate sensors according to their needs.

[0089] like Figure 3 As shown, in the endoscope lens cleaning and defogging device of the present invention, the heating box 11 has an internal electric heating wire 112 and a temperature sensor 113.

[0090] The electric heating wire 112 and the temperature sensor 113 are respectively electrically connected to the microprocessor 43 of the control component 4.

[0094] The endoscope lens cleaning and defogging device of this application embodiment is composed of a disposable cleaning brush 231 and a motor 232. The brush rod 2312 of the cleaning brush 231 passes through the opening at the cleaning sleeve 211 to the output shaft of the motor 232.

[0095] The brush head 2311 is designed as a ring and is an absorbent sponge brush, with the lens passing through the middle of the brush body; the diameter of a typical endoscope lens is 10mm, so a diameter of 12mm for the cleaning brush 231 is sufficient for use.

[0096] At the same time, the lens assembly can also be manually rotated to thoroughly clean it; the brush head 2311 is located at one end of the cleaning sleeve 211, and when cleaning is required, the cavity lens can be rotated so that the brush head 2311 can thoroughly clean the cavity lens.

[0097] like Figure 6 As shown, the endoscope lens cleaning and defogging device of the present invention includes a control component 4 comprising a control box 41, a PCB circuit board 42 disposed therein, a microprocessor 43 integrated on the PCB circuit board 42, a power supply component 44, a micro temperature controller 45, an alarm component 46, and a power on / off switch 47 disposed on the surface of the control box 41.
