Medical speculum filling pump

Abstract

The invention discloses a medical speculum filling pump which comprises a water supplying device, a speculum camera shooting water outlet device and a video recognition module. The water supplying device comprises a pump body and a heat exchanger, a first water inlet of the pump body is communicated with an external water supplying device, a first water outlet of the pump body is communicated with a second water inlet of the heat exchanger through a water pipe, and a second water outlet of the heat exchanger is communicated to a water outlet pipe of the speculum camera shooting water outlet device through a water pipe. The speculum camera shooting water outlet device comprises a video collector and a water outlet pipe with a check valve, the water pipe between the heat exchanger and the speculum camera shooting water outlet device is further provided with a temperature sensor and a first pressure sensor, and a second pressure sensor is arranged at the position, in front of the check valve, of the water outlet pipe. The video recognition module comprises a video receiving processing module and a video storage module, wherein the video receiving processing module is connected with the video collector and the video storage module. The medical speculum filling pump is simple in structure, convenient to operate, practical and safe.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a perfusion pump for a medical speculum. Background technique [0002] In recent years, minimally invasive treatment of tumors has attracted widespread attention due to its advantages of less trauma, fewer complications, and less pain for patients. During minimally invasive surgery, local high temperature or appendages such as smoke will be generated, as well as excised tissues, bleeding and stones, etc., all need to be washed with water. [0003] In the prior art, traditional Chinese medical endoscopes and medical perfusion pumps are widely used in clinical surgery and minimally invasive surgery. Through the surgical channel established during the operation, the water flow is flushed to the site where the operation is performed with an appropriate pressure to avoid the Local high temperature is generated to ensure a clear view of the intracavitary operation, and at the same t...

Problems solved by technology

However, the temperature of the perfusion water of the existing medical perfusion pump is generally the ambient temperature of the operating room, and the difference between the perfusion flushing fluid and the body temperature is more than 10 degrees. Especially in the percutaneous nephrolithotomy operation, a large amount of perfusion fluid flushing (3000-30000 ml) is required to ensure The surgical field of view is clear, so long-term perfusion and irrigation during the operation will take away a lot of body heat, which may lead to a drop in core body temperature and complications caused by postoperative hypothermia
