Abstract

The utility model belongs to the technical field of medical devices, and relates to a device for washing and wiping a lens of a cavity mirror, which comprises four components of a tube of the cavity lens, a flushing system, a scrubbing system and a control switch. The laparoscopic sleeve is an eccentric sleeve composed of two cylindrical sleeves. A flushing system, a mirror cleaning system and a control switch are arranged on the thicker side of the sleeve. The flushing system includes a water jet slightly protruding from the mirror surface, a flushing pipe and an end interface. The flushing system realizes the water spray action through the control switch. The mirror cleaning system consists of an elastic sheet lined with absorbent cotton, buckles and sliding rods. The mirror cleaning system also realizes the mirror cleaning action through the same control switch. The utility model integrates the flushing system and the mirror cleaning system, and is controlled by the same switch. It is not necessary to take the laparoscope out of the body, which greatly shortens the time spent on cleaning the mirror and re-entering the country to find the original surgical field during the entire operation process. At the same time, the risk of infection is reduced, especially in the case of intracavitary hemorrhage, which has obvious advantages over manual mirror wiping outside the cavity.

Description

A mirror cleaning device for laparoscopic lens

technical field

The utility model relates to the field of medical equipment, and is designed as a cavity mirror auxiliary device with a washing lens and a wiping lens.

Background technique

Laparoscope (such as chest, laparoscope, etc.) is a surgical instrument with a lens. It is an instrument for inserting a laparoscope into a patient's body cavity to assist in surgical operations and intra-abdominal inspections. As an important part of minimally invasive surgery, laparoscopic surgery has become one of the future development directions of surgery due to its advantages of less trauma, less postoperative pain, lower incidence of infection, and wider operation range than open surgery. With the popularization of laparoscopic surgery, minimally invasive surgery plays an increasingly important role in various surgical operations. During laparoscopic surgery, because there is a temperature difference between the inside and outside of the body cavity or the temperature difference between the two sides of the objective lens when cutting tissue, fog will be formed on the objective lens of the laparoscope; in addition, when tissue is cut or blood vessels are accidentally damaged, blood stains may splash onto the objective lens. Therefore, fog and blood stains often appear on the objective lens during laparoscopic surgery, affecting the surgical field of view. When fog and blood stains appear on the objective lens, the clinical operation often needs to be temporarily interrupted, and the endoscope is taken out from the body cavity, and the objective lens is scrubbed clean before re-entering the body cavity before continuing the operation, which increases the time-consuming operation and reduces the efficiency of the operation , it will increase the risk of intracavitary or wound infection, especially when the blood vessels in the body cavity are bleeding, cleaning the lens outside the body will waste the time for emergency hemostasis, and a large amount of blood loss will cause hemorrhagic shock and endanger the life of the patient.

The patent with the authorized notification number CN 202446249 U discloses a laparoscopic lens washing and drying device, including a sleeve, a washing tube, a drying assembly, a connector and a handle.
