Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an integrated endoscopic surgical device for removing intestinal polyps. Background Art

[0002] With the development of digestive endoscopy technology, the indications for minimally invasive endoscopic treatment have been continuously expanded, and endoscopic submucosal dissection, endoscopic mucosal resection, and polypectomy have been gradually popularized.

[0003] Traditionally, most endoscopic surgical devices are single-instrument-channel endoscopes, that is, only a lens and a cutting mechanism can be arranged in the channel. When removing intestinal polyps, only cutting can be performed, and no lifting action can be provided during the cutting of polyps. Therefore, the doctor's personal skills and experience are highly required during the entire surgical process, which increases the risk of surgical complications and prolongs the surgical time. Currently, dual-instrument-channel endoscopic surgical devices have gradually emerged on the market. For example, the "A Digestive Tract Surgery-Assisting Robot System" with the publication (announcement) number of CN108354668B adds an external auxiliary instrument cavity on the basis of the original single-instrument channel, and a multi-degree-of-freedom robotic arm is arranged in the cavity to cooperate with the endoscope and the electrocautery knife to jointly achieve the functions of lifting and cutting the target mucosa. However, there is only a pair of clips at the end of the robotic arm, so only a single polyp can be clamped and lifted. For intestinal polyps, the phenomenon of multiple polyps often occurs. Therefore, the existing endoscopic surgical devices cannot meet the requirement of removing a polyp group at one time, and repeated operations are required multiple times, which prolongs the resection time and greatly increases the surgical risk.

At a position near the rear end on the outer peripheral wall of the cylindrical member 6.1, there is a first annular groove 6.1.10 that is snap-fitted with the top of the clamp 14, so as to facilitate the fixed connection of the auxiliary component 6 and the front end of the auxiliary sleeve 5 with the front end of the main sleeve 2. In order to facilitate the insertion in the intestine, the front end of the cylindrical member 6.1 is set in a hemispherical shape.

The third air pipe 9 is sleeved on the rear end of the pipe member 6.4.1; the fourth air pipe 10 is sleeved on the rear end of the collection chamber 6.1.4.

[0023] The pressure exhaust assembly 11 is used to adjust the air pressure on the front and rear sides of the plug body 6.4.2 through the first air pipe 7 and the second air pipe 8. Among them, the pressure exhaust assembly 11 includes a high-pressure gas tank 11.1 and a booster air pump 11.2 provided on the top of the high-pressure gas tank 11.1 for inputting high-pressure gas into the high-pressure gas tank 11.1. A connection cavity 11.3 is provided on the side wall of the top end of the high-pressure gas tank 11.1. An intake solenoid valve one 11.4 and an intake solenoid valve two 11.7 are sleeved on the side wall of the connection cavity 11.3. The output ends of the intake solenoid valve one 11.4 and the intake solenoid valve two 11.7 are respectively connected to a first three-way joint 11.5 and a second three-way joint 11.8. The front ends of the first three-way joint 11.5 and the second three-way joint 11.8 are respectively connected to the rear ends of the first air pipe 7 and the second air pipe 8. Exhaust solenoid valves one 11.6 and two 11.9 are respectively installed at the top ports of the first three-way joint 11.5 and the second three-way joint 11.8. A pressure relief valve 11.10 is installed on the side wall of the top end of the high-pressure gas tank 11.1.

[0024] The negative pressure assembly 12 is used to provide a negative pressure state for the pipe fitting 6.4.1 and the collection cavity 6.1.4 through the third air pipe 9 and the fourth air pipe 10 respectively. Among them, the negative pressure assembly 12 includes a suction pump 12.1, a negative pressure three-way joint 12.2 with its middle port connected to the input end of the suction pump 12.1, a first negative pressure suction pipe 12.3 and a second negative pressure suction pipe 12.5 connected to the two side ports of the negative pressure three-way joint 12.2, and a first negative pressure solenoid valve 12.4 and a second negative pressure solenoid valve 12.6 respectively connected to the front ends of the first negative pressure suction pipe 12.3 and the second negative pressure suction pipe 12.5. The front ends of the first negative pressure solenoid valve 12.4 and the second negative pressure solenoid valve 12.6 are respectively connected to the third air pipe 9 and the fourth air pipe 10.

[0025] In summary, when performing an intestinal polyp resection operation, according to the operation of conventional endoscopic surgery, the main sleeve 2 and the auxiliary sleeve 5 are inserted into the intestine under the guiding action of the columnar member 6.1. The insertion depth is judged and designed and the steering is adjusted through the image collected by the camera 3, so that the suction cup 6.2 and the electrocautery 4 are both oriented towards the polyp part to be resected.

[0026] First, open the intake solenoid valve two 11.7 and the exhaust solenoid valve one 11.6, so that the high-pressure gas sequentially enters the rear part of the piston cavity 6.1.2 through the second three-way joint 11.8, the second air pipe 8, and the second jack 6.1.6. The high-pressure gas pushes the plug body 6.4.2 forward. The plug body 6.4.2 moves forward and sleeves in the piston cavity 6.1.2, and pushes the flexible air pipe 6.3 forward through the pipe fitting 6.4.1. The flexible air pipe 6.3 pushes the suction cup 6.2 out of the radial hole 6.1.1, so that the suction cup 6.2 fits on the polyp to be resected. At the same time, the gas in the front part of the piston cavity 6.1.2 is discharged sequentially from the first jack 6.1.5, the first air pipe 7, and the first three-way joint 11.5 through the exhaust solenoid valve one 11.6.

[0027] Subsequently, the suction pump 12.1 is started, and at the same time, the first negative pressure solenoid valve 12.4 is opened, so that the inner cavity of the suction cup 6.2 is in a negative pressure state, thereby adsorbing the polyp to be removed; then the pressure on both sides of the plug body 6.4.2 is adjusted (that is, the first air inlet solenoid valve 11.4 and the second exhaust solenoid valve 11.9 are first opened, so that the high-pressure gas sequentially enters the front part of the piston cavity 6.1.2 from the first three-way joint 11.5, the first trachea 7, and the first jack 6.1.5), so that the plug body 6.4.2 slightly moves backward in the piston cavity 6.1.2 by a certain distance, and the pipe fitting 6.4.1 pulls the suction cup 6.2 through the flexible trachea 6.3 to achieve the lifting effect on the polyp to be removed, so as to facilitate the electric knife 4 to remove the lifted polyp.

[0028] Continue to supply high-pressure gas into the front cavity of the piston cavity 6.1.2, so that the plug body 6.4.2 continues to move backward until the suction cup 6.4.2 together with the removed polyp enters the radial hole 6.1.1.

[0029] Then, the second negative pressure solenoid valve 12.6 is opened, and at the same time, the first negative pressure solenoid valve 12.4 is closed, so that the collecting cavity 6.1.4 is in a negative pressure state, and the removed polyp is sucked into the rear end of the collecting cavity 6.1.4. Thus, a polyp removal and collection cycle is completed.

[0030] And so on, all the polyp particles in the polyp group are removed and collected in accordance with the above steps. Finally, the main sleeve 2 and the auxiliary sleeve 5 are withdrawn from the intestine, and the removed polyps in the collecting cavity 6.1.4 are cleared. And the equipment is disinfected.

[0031] In order to prevent the removed polyp adsorbed by the suction cup 6.2 from colliding with the orifice of the radial hole 6.1.1 when entering the radial hole 6.1.1 and causing the polyp to fall off, a short pipe 6.2.1 fixedly connected to the front end of the flexible trachea 6.3 is provided at the top of the suction cup 6.2, and a plurality of flexible flaps 6.2.2 are provided along the circumferential direction on the outer edge of the suction cup 6.2. When the removed polyp enters the radial hole 6.1.1 along with the suction cup 6.2, the orifice will form a closing effect on the flexible flaps 6.2.2, so that the flexible flaps 6.2.2 wrap the polyp to ensure that the polyp smoothly enters the radial hole 6.1.1.

[0032] In order to prevent the removed polyp inhaled into the collecting cavity 6.1.4 from falling off from the front end of the collecting cavity 6.1.4 through the radial hole 6.1.1, a flexible membrane flap 6.1.7 is provided on the peripheral wall of the collecting cavity 6.1.4 near the front end. The flexible membrane flap 6.1.7 forms a one-way opening "door panel" to prevent the removed polyp from falling off when the negative pressure in the collecting cavity 6.1.4 disappears. A filter screen 6.1.8 is provided at a position near the rear end of the collecting cavity 6.1.4, that is, the removed polyp is intercepted in the cavity between the filter screen 6.1.8 and the flexible membrane flap 6.1.7 to prevent the removed polyp from entering the fourth trachea 10 and causing a blockage phenomenon.

[0033] To prevent the intestinal substances aspirated by the third trachea 9 and the fourth trachea 10 from entering the suction pump 12.1, collection boxes 13 are respectively connected between the first negative pressure solenoid valve 12.4 and the third trachea 9, and between the second negative pressure solenoid valve 12.6 and the fourth trachea 10. Among them, the collection box 13 includes a horizontally placed cup body 13.1 and a cover body 13.2 buckled to the front end of the horizontally placed cup body 13.1. At the top of the rear end of the horizontally placed cup body 13.1, interfaces two 13.4 corresponding to the first negative pressure solenoid valve 12.4 and the second negative pressure solenoid valve 12.6 are respectively provided. A sleeve of the front wall of the cover body 13.2 is provided with interfaces one 13.3 corresponding to the third trachea 9 and the fourth trachea 10. That is, when a small part of the substances aspirated by the third trachea 9 and the fourth trachea 10 enter the collection box 13, they will fall to the bottom of the horizontally placed cup body 13.1; removing the cover body 13.2 from the horizontally placed cup body 13.1 can facilitate the removal of the intestinal substances accumulated in the horizontally placed cup body 13.1.
