Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to a complete set of automatic cleaning devices for laparoscope lenses, which can clean the lenses at any time during an operation. Background Art

[0002] Laparoscopic surgery is a newly developed minimally invasive method that makes it possible to perform surgery through smaller incisions. In this way, the damage to tissues is less than that of traditional surgical operations. Through a keyhole-sized incision, surgeons can insert a small light source, a camera and surgical instruments. The surgeon guides the operation of surgical instruments to perform surgery through the image transmitted to the monitor. The laparoscope includes a tube, an image transmission channel arranged inside the tube, a lens is arranged at the front end of the image transmission channel, and the lens is arranged in an inclined manner. A light source optical fiber channel is also arranged inside the tube, and a handle is arranged at the rear end of the tube. During laparoscopic surgery, the tube is inserted into the abdominal cavity for image search. During the operation, blood or grease in the abdominal cavity may contaminate the lens area, resulting in unclear surgical field. In addition, because the lens and surgical instruments are in the body, it is impossible to quickly clean the lens and restore the surgical field. To solve this problem, the conventional method is to remove the tube and clean it outside the body, which will cause the operation to be suspended and increase the operation time. At the same time, the doctor cannot observe the patient's abdominal cavity status in time, which poses a huge safety hazard. In recent years, other special trocars have appeared, which are equipped with flushing and cleaning channels. When in use, the scope tube is returned to the trocar channel to provide continuous water flow to complete the lens cleaning. They are relatively convenient to use, but the forward and backward movement of the scope tube may lead to the loss of the surgical field. After reinserting the scope tube, the surgical site needs to be found again. Summary of the invention

The working state of the air pump can be configured to be air extraction or air discharge. When configured to be air extraction, the liquid collection bottle can be used to collect the residual liquid during flushing. When configured to be air discharge, the liquid collection bottle is not required. The host 1 is also provided with a temperature control switch, an air pump speed control switch 16 and a peristaltic pump speed control switch 17. The power of the air pump and the peristaltic pump 12 are respectively adjusted and controlled by the corresponding speed control switches.

The heating platform 13 has a heating chamber 133 composed of a chassis 131 and an outer peripheral cylinder wall 132, and a receiving port 1311 is also provided in the center of the chassis 131. The liquid supply bottle can be inverted in the heating chamber 133, and the bottle head can extend from the receiving port 1311. The flushing tube has a heating and constant temperature function for heating the flushing liquid in the internal flushing channel. For example, heating is performed by a heating wire or a heating plate.

[0028] The internal flushing channel of the flushing tube may be provided with one, which is connected to the air pump (which can suck or spray air) and the peristaltic pump at the same time, for flushing the lens of the laparoscope or absorbing the body fluid; or provided with two, respectively connected to the air pump and the peristaltic pump, or provided with more than two. Multiple internal flushing channels are connected. One or more flushing holes may be provided, for spraying out flushing liquid or sucking in body fluid. The flushing liquid may be sterile saline or clean water. The internal flushing channel can also serve as an air supply channel, thereby providing a high-pressure airflow to quickly blow away the residual water stains near the lens; or as an air suction channel, the residual water stains near the lens can be quickly sucked away. The control switch is a three-stage bridge switch. When the switch is horizontal, the flushing, spraying or exhausting functions are turned off; pressing one side of the switch activates the flushing function; similarly, pressing the other side of the switch activates the jet or exhaust function.

[0029] The flushing tube of the device has a simple structure and low cost. It can be manufactured through conventional processing methods such as 3D printing, injection molding, and extrusion, and is compatible with ordinary trocars and can be customized according to the length of the laparoscope.

[0031] When in use, place the liquid supply bottle on the heating platform 13 and keep the temperature of the water outlet slightly higher than the body temperature to avoid fogging of the lens 22. Connect the external peristaltic pump 12 to the liquid supply bottle, and control the water outlet for flushing or absorbing the body fluid through the control switch 61, and control the flow rate of the flushing water flow and the suction air flow respectively through the speed regulating knob.

[0032] The flushing tube, filter, liquid collection bottle and pipeline in the present invention are disposable, which can avoid cross infection of patients and facilitate the cleaning and maintenance of the main unit.
