Description

Technical Field

[0001] The utility model belongs to the technical field of wireless cavity mirrors, and in particular relates to a wireless cavity mirror with convenient replacement of cold light sources. Background Art

[0002] Wireless laparoscope is an advanced medical technology that transmits endoscopic images from the patient's body to an external display through wireless transmission. During the operation, the wireless laparoscope captures images from the patient's body through its built-in camera and transmits these images to an external display in real time via wireless signals. Doctors can guide surgical operations by viewing the images on the display without having to directly observe the patient's body.

[0003] Currently, a Chinese patent with the announcement number CN217960037U discloses a laparoscope with a camera that can be rotated up and down to expand the surgical field. The laparoscope comprises a base and a shaft. The shaft is a hollow cylindrical structure with openings at both ends. A partition is disposed transversely in the middle of the shaft, separating an image transmission chamber and an irrigation chamber. A rotary motor is fixedly disposed on the end of the partition facing the base, and the output rotary shaft of the rotary motor is connected to a sleeve. A telescopic motor is fixedly disposed in the middle of the sleeve, and the output telescopic shaft of the telescopic motor is connected to a wireless camera. An LED cold light source is fixedly mounted on one end of the shaft located in the irrigation chamber. This laparoscope with a camera that can be rotated up and down to expand the surgical field expands the surgical field of view, providing the surgeon with a better surgical field. It can fully expose the surgical operation area, cleverly avoid the surgeon's manipulation of instruments, and avoid frequent changes in patient position, further improving surgical safety and reducing intraoperative and postoperative complications.

[0004] However, when the above device is in use, an LED cold light source is fixedly installed on one end of the mirror rod located in the flushing cavity. Since the LED cold light source needs to be external to ensure the lighting effect for the camera, the user may easily cause it to collide with a hard object such as a desktop and be damaged due to improper operation. However, the cold light source of the device is difficult to disassemble, which is inconvenient for the staff to operate. Therefore, a wireless laparoscope that is easy to replace the cold light source is needed. Utility Model Content
