Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a disposable puncture device that can emit light. Background Art

[0002] Technological advances have made it possible to perform surgery through smaller incisions. This way, the tissue is less damaged than in traditional surgery. Through a keyhole-sized incision, surgeons can insert tiny light sources, cameras, and surgical instruments. Surgeons use images transmitted to a monitor to guide the operation of surgical instruments. Robotic surgery was developed from traditional laparoscopic surgery. Both are based on laparoscopic operating systems and fall into the category of minimally invasive surgery.

[0003] In laparoscopic or robotic surgery, the light source in the surgical area comes from the lens. The light source of the lens directly illuminates the surgical area so that the surgeon and assistant can see the surgical area clearly. In long-term practice, this method has two disadvantages: the light source of the lens directly illuminates the surgical area. In order for the surgeon and assistant to see the surgical area clearly, the brightness is generally adjusted to a relatively high level, which makes it easy for reflections to occur in the field of vision and shortens the service life of the lens bulb; the surgeon and assistant have different operating focuses. The current light source mainly cooperates with the surgeon's operation, causing the assistant to occasionally operate in the "dark". If there are multiple sources of light, the brightness of a single light source does not need to be too bright, and the light in the entire surgical field of view will be more uniform.

The LED light block 31 is installed at the head end of the puncture sleeve 11 and is electrically connected to the electric wire 33. The electric wire 33 passes through the power supply tube 14 and is connected to the power supply.

[0030] Specifically, when the device is used, the puncture cone 21 is first inserted into the puncture cannula 11 through the sealing rubber ring 15 on the tail seat 12, and then the head end of the puncture cone 21 together with the head end of the puncture cannula 11 is inserted from the patient's wound to the visceral area that needs to be treated or observed. Then, the puncture cone 21 is pulled out by holding the tail seat 12, and the sealing rubber ring 15 will be closed when it is pulled out. At the same time, the gas injection valve 13 is also in a closed state, and the puncture cannula 11 and the patient's body form a closed space. The subsequent laparoscope or robotic surgical instrument is then inserted into the sealing rubber ring 15 into the puncture cannula 11 and then into the patient's body to treat or observe. Observation, the gas injection valve 13 is used to inject carbon dioxide or inhale. When treatment or observation is performed, the wire 33 in the power tube 14 is connected to the power supply, and the LED light block 31 lights up to illuminate the patient's internal organs area close to the head end of the puncture cannula 11. On the basis of the light source of the laparoscope or robot camera, the device directly emits light from the puncture cannula 11, and does not need to rely on the laparoscope or robot surgical instrument camera to emit light, and there will be no reflection problem. During an operation, multiple parts need to be punctured, and each puncture cannula 11 can be illuminated to ensure the smooth progress of the operation.

[0031] In some possible embodiments, the head end of the puncture cannula 11 is a 45° inclined opening; there are two wiring grooves 32, which are respectively located at the tip and concave ends of the inclined surface of the head end of the puncture cannula 11; there are two wires 33, which are respectively located in the two wiring grooves 32; there are two LED light blocks 31, which are respectively located at the tip and concave ends of the head end of the puncture cannula 11 and are electrically connected to the two wires 33.

[0032] Specifically, the inclined opening at the head end of the puncture sleeve 11 makes it easier for it to enter the human body along with the puncture cone 21, while a flat head is prone to secondary damage to the wound; the tip of the puncture sleeve 11 is located at the front end, and an LED light block 31 is arranged at the tip to make its irradiation area larger, helping medical staff to see the internal situation more clearly. The concave end of the inclined surface of the head end of the puncture sleeve is located opposite to the tip, and an LED light block 31 is also arranged at the concave end to ensure a more comprehensive lighting area.

[0033] In some possible embodiments, the tip and concave end of the inclined surface at the head end of the puncture sleeve 11 are respectively provided with light grooves 34, and the two LED light blocks 31 are respectively snapped into the two light grooves 34. The two LED light blocks 31 both have two light-emitting surfaces, and the two light-emitting surfaces are respectively facing the outside and the bottom of the puncture sleeve 11.

[0034] Specifically, as shown in the figure, a lamp groove 34 is opened at the tip and concave end of the inclined surface of the head end of the puncture cannula 11, and the LED lamp block 31 is embedded therein. The three sides of the LED lamp block 31 are connected to the puncture cannula 11, and the two side surfaces and the bottom surface of the LED lamp block 31 are not blocked, and the bottom surface of the LED lamp block 31 and the outer side surface not facing the inside of the puncture cannula 11 are the light-emitting surfaces. When the LED lamp block 31 is working, the light source is directed to the bottom and outer side of the puncture cannula 11, which can better illuminate the patient's body and have a wider lighting range.

[0035] In some possible embodiments, the lighting assembly 3 also includes: an external wire 35, one end of which is detachably connected to the power tube 14 and electrically connected to the wire 33, and the other end of the external wire 35 is connected to the external power supply; a dimmer switch 36, which is arranged on the external wire 35.

[0036] Specifically, the external wire 35 connects the LED light block 31 to an external power source, and the dimmer switch 36 can control the opening and closing and brightness of the LED light block 31. When in use, medical staff turn the dimmer switch 36, adjust the resistance of the external wire 35, and then control the brightness of the LED light block 31. It can be adjusted according to the specific conditions during the operation, so that the brightness of the LED light block 31 meets the most suitable conditions for the operation for the lighting inside the patient's body, which is conducive to better progress of the operation. At the same time, the rotation adjustment is relatively simple and convenient to use.

[0037] In some possible implementations, one end of the external wire 35 is a circular electrical connector 351, a circular socket 141 matching the circular electrical connector 351 is provided on the power tube 14, the wire 33 is electrically connected to the circular socket 141, and the circular electrical connector 351 is plugged into the circular socket 141.

[0038] Specifically, the circular electrical connector 351 has good safety and stability, and has excellent corrosion resistance and wear resistance and will not be affected by the surgical environment. It is easy to install. When in use, the circular electrical connector 351 can be inserted into the circular socket 141 on the power tube 14; the connection between the power tube 14 and the tail seat 12 is sealed to prevent body fluids or blood from splashing into the power tube 14 during surgery to cause a short circuit, and to prevent bacteria in the power tube 14 from contaminating the puncture sleeve 11.

[0039] In some possible implementations, the puncture cannula 11 and the tail seat are both made of medical polyvinyl chloride material 12; and the gas injection valve 13 is a stop valve.

[0040] Specifically, medical polyvinyl chloride material has certain anti-coagulation and flexibility, and is cheap and low in cost, making it suitable for disposable medical devices; the opening and closing of the stop valve can be done by a stop switch, which is more convenient to use.

[0041] In some possible implementations, a knob 23 is provided at one end of the puncture seat 22 away from the puncture cone 21 .

[0042] Specifically, the knob 23 provided on the puncture seat 22 helps medical personnel to pull out the puncture cone 21 .
