Description

Surgical endoscope defogging device

technical field

The utility model relates to a defogging device, in particular to a surgical endoscopic defogging device suitable for medical endoscopic surgery.

Background technique

Laparoscopic surgery is an emerging minimally invasive surgery. It uses laparoscope and related instruments for surgery, uses cold light source illumination, inserts the laparoscopic lens into the abdominal cavity through a small incision, and uses digital camera technology to display the images captured by the laparoscopic lens on a special monitor in real time. The patient's organ image displayed on the monitor screen analyzes and judges the patient's condition, and uses special laparoscopic instruments for surgery. Laparoscopic surgery can effectively avoid leaving excessive trauma and scars on the abdomen of patients, leaving only 1 to 3 small scars of 0.5 to 1 cm, with minimal trauma, reducing the risk of surgery and pain, and allowing patients to recover after surgery. Shortening and reducing the surgical expenditure of patients is a surgical project that has developed rapidly in recent years.

A frequently encountered problem in laparoscopic surgery is the fogging of the laparoscopic lens, which directly affects the clarity of the surgical field of view on the monitor. The fogging of the laparoscopic lens is generally caused by the temperature difference between inside and outside the body. Therefore, in order to avoid fogging of the laparoscopic lens in the body, it is necessary to heat the laparoscopic lens to a temperature similar to the body temperature before entering the abdominal cavity. At present, the clinically adopted method of defogging the laparoscope is to heat sterile saline to 37°C to 50°C and then pour it into a sterilized thermos cup for use. After taking it out, insert it into a thermos cup, and then insert it into the patient's abdominal cavity again after warming it with warm physiological saline to remove the fog.

The technical problems existing in the prior art are: (1) The existing thermos cups are generally household thermos cups, and the household thermos cups are made of stainless steel. High maintenance costs after eyepiece damage cause medical costs to rise. In order to avoid the occurrence of this problem, those skilled in the art have designed a lining that matches the shape of the cup body, and the lining is generally made of silicone material. When in use, put the inner liner into the thermos cup, and the inner liner can protect the eyepiece of the endoscope. However, this design still has certain risks. The lining and the inner wall of the thermos cup are in a fit state. When the endoscope reaches into the lining and touches the inner wall of the thermos cup, it will also touch the inner wall of the thermos cup at the same time, which cannot completely avoid the collision between the endoscope and the inner wall of the thermos cup. touch. (2) The bottom of the household thermos cup is generally made of powdered material or foam material for weighting, which is not suitable for frequent high temperature and high pressure sterilization in medical use. Sterilization failed. (3) The household thermos cup is easy to be dumped during the operation. It needs to be carefully placed on the operating table after each defogging operation to avoid the spilling of the normal saline caused by the dumping, which will bring inconvenience to the operation.

How to solve the above-mentioned problems in the prior art is still a research hotspot for those skilled in the art.
