Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a laparoscope lens rinsing device that can clean the lens at any time during surgery. Background Technology

[0002] Laparoscopic surgery is a newly developed minimally invasive technique that makes it possible to perform surgery through smaller incisions. This results in less tissue damage than traditional surgery. Through a keyhole-sized incision, surgeons can insert tiny light sources, cameras, and surgical instruments. The surgeon guides the manipulation of the surgical instruments based on images transmitted to a monitor. A laparoscopy system includes a tube, an image transmission channel within the tube, a lens at the front end of the image transmission channel (tilted), a fiber optic channel for the light source inside the tube, and a handle at the rear end of the tube. During laparoscopic surgery, the tube is inserted into the abdominal cavity for imaging. However, blood or grease in the abdominal cavity can contaminate the lens area, leading to an unclear surgical field. Furthermore, because the lens and surgical instruments are inside the body, it is difficult to quickly clean the lens and restore the surgical field. The conventional method to address this issue is to remove the tube and clean it externally, which interrupts the surgery, increases surgical time, and prevents the surgeon from timely monitoring of the patient's abdominal cavity, posing significant safety risks. In recent years, other specialized trocars have also emerged, which are equipped with a water-washing channel. When in use, the endoscope tube is retracted into the trocar channel to provide a continuous flow of water for cleaning the lens. They are relatively convenient to use, but the back-and-forth movement of the endoscope tube may cause the surgical field to be lost, and the surgical point needs to be re-found after the endoscope tube is reinserted.

[0039] The internal flushing channel of the flushing pipe can be provided with one channel connected with the air pump (suction or jet) and the water supply pump for flushing or sucking the liquid in the body cavity, or provided with two channels connected with the air pump and the water supply pump respectively, or more than two channels. The multiple internal flushing channels are communicated. The flushing hole can be provided with one or more for jetting the flushing liquid or sucking the liquid in the body cavity. The flushing liquid can be sterile normal saline or clean water. The internal flushing channel can serve as the air supply channel to provide high-pressure air flow to quickly dry the residual water stains near the lens, or as the air suction channel to quickly suck the residual water stains near the lens. The flushing pipe is provided with a heating constant temperature function for heating the flushing liquid in the internal flushing channel. The heating is achieved by heating wires or heating sheets. The water flushing or liquid sucking in the body cavity can be controlled by the control switch 61. The control switch is a three-stage bridge switch. When the switch is horizontal, the functions of flushing water, jetting air or sucking air are closed. When one side of the switch is pressed, the water flushing function is activated. Similarly, when the other side of the switch is pressed, the air jetting or sucking function is activated.

[0040] The flushing pipe structure of the device is simple and low in cost. The device can be manufactured by conventional processing methods such as 3D printing, injection molding and extrusion, and can be compatible with ordinary puncture devices. The device can be customized according to the length of the endoscope.

[0041] During assembly, the endoscope lens tube 11 is inserted into the lens tube insertion channel 21 of the flushing pipe 2 of the device, and then the controller 6 in the adjusting assembly 3 arranged at the rear end of the flushing pipe 2 is arranged on the endoscope. Specifically, the pipe clamp head 62 is clamped on the rear end of the lens tube 11, and the U-shaped clamp 63 is clamped on the positioning column 131, so as to ensure the direction of the lens tube 11 inserted into the flushing pipe 2, so that the lens 12 is inclined towards the flushing hole.

[0042] Then the flushing pipe and the lens tube are combined together and placed in the ordinary puncture device. The circular pipe section 25 of the flushing pipe and the sealing ring of the puncture device are sealed to prevent gas leakage during the operation. By rotating the adjusting knob 311 to drive the gear to rotate, the axial relative position of the lens 12 and the flushing pipe 2 is adjusted for fine adjustment, so that the lens 12 corresponds to the front end opening 23 of the flushing pipe 2, and the lens 12 is better exposed to the surrounding field of view. The inclined surface of the lens 12 faces the flushing hole 211 at a suitable position, the flushing effect of the flushing hole 211 on the lens 12 is good, and the requirement of cleaning the endoscope lens in the channel is met, and the endoscope does not need to be removed for cleaning.
