[0050] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , an aspiration tube with electrocoagulation function comprises

[0051] The aspiration tube 1 has an aspiration cavity 2.

[0052] The adjusting assembly 3 has an adjusting cavity 4, and the adjusting cavity 4 is communicated with the aspiration cavity 2, and the adjusting assembly 3 further has a vacuum degree adjusting piece 5.

[0053] The suction assembly 6 is connected with the adjusting assembly 3, and the suction end of the suction assembly 6 is communicated with the adjusting cavity 4.

[0054] The electrocoagulation assembly 7 is installed on the aspiration tube 1, and the electrocoagulation end of the electrocoagulation assembly 7 is located at the end of the aspiration tube 1.

[0055] The utility model discloses a suction pipe 1 end is inserted to the wounded place through the endoscope channel, and the suction component 6 suction makes the suction cavity 2 have certain vacuum degree, is favorable to the suction of the bleeding or the blood clot of the wounded place, and the vacuum degree adjusting assembly 5 is used for adjusting the vacuum degree of suction cavity 2, is favorable to the real -time adjustment according to different wounded position and bleeding amount,

[0056] Meanwhile, the electrocoagulation assembly 7 is used for electrocoagulation hemostasis and scabbing under the cooperation of the endoscope, blood, body fluid and smoke generated by electrocoagulation hemostasis are quickly extracted by the suction pipe 1, and too many instruments do not have to be built into the endoscope channel, so as to reduce interference.

[0057] The suction pipe 1 and the electrocoagulation assembly 7 are prepared as a whole, the functions are integrated, miniaturization, the waste of the wounded place is discharged while electrocoagulation hemostasis, the electrocoagulation scabbed place is kept clean, it is favorable to the functional use of narrow channel operation such as neuroendoscopic surgery, avoids expanding the operation channel, excessive traction and the like, reduces the secondary injury to the patient, and improves the functional prognosis of the functional patient.

[0058] As shown in Figure 1 , Figure 2 As shown in some embodiments, the adjusting assembly 3 includes an adjusting block 8, which can be made of stainless steel, and an adjusting cavity 4 is located in the adjusting block 8. The vacuum degree adjusting member 5 includes a vacuum degree adjusting hole 9, which is in communication with the adjusting cavity 4. Specifically, the vacuum degree adjusting hole 9 includes an arc-shaped hole 10 and a rectangular hole 11, which are in communication. The arc-shaped hole 10 is used for coarse adjustment, and the rectangular hole 11 is used for fine adjustment. When a medical staff holds the adjusting block 8 and presses the arc-shaped hole 10 and the rectangular hole 11 with the thumb, the vacuum degree in the suction cavity 2 can be accurately controlled according to the opening degree of the arc-shaped hole 10 and the rectangular hole 11, so as to avoid damage to the wounded place of the patient caused by excessive vacuum degree of the suction cavity 2.

[0059] In another embodiment, the suction component 6 includes a suction pipe 12, which is in communication with the adjusting cavity 4, and the other end of the suction pipe 12 is connected with a suction device. Specifically, the end of the suction pipe 12 is connected with the suction device through a quick connector. The suction device is used to create a vacuum in the adjusting cavity 4 and the suction cavity 2, so as to facilitate the suction of waste from the wounded place. In order to facilitate the observation of bleeding and coagulation in human tissues, the end of the suction pipe 12 is provided with an imaging module in some embodiments. The pipe wall of the suction pipe 12 is usually made of PET material, which has a smooth inner wall and a specific shape of the pipe body, so as to facilitate the suction and transportation of blood or thrombus. Some suction pipes 12 can have a metal braided structure to increase their pushability and resistance to folding. The suction pipe 12 also has sufficient strength to avoid rupture or leakage. The suction pipe 12 is coated with an anti-adsorption coating to reduce the adsorption and coagulation of blood components. The side of the end of the suction pipe 12 is provided with a side hole, which is in communication with the suction cavity 2. The side hole facilitates the medical staff to suck the coagulation from multiple directions, and reduces the swing amplitude of the suction pipe 12.

[0060] When using the suction tube 12, the suction tube needs to be flushed first to activate the hydrophilic coating and generate negative pressure through the connected syringe. Under the condition of fluoroscopy, the suction tube is gently and slowly advanced to the thrombus position, and then the suction is started. The suction tube 12 is moved forward and backward in the occluded blood vessel. During the suction process, sufficient negative pressure should be maintained, and the advancing speed of the suction catheter should not be too fast. When using the suction tube 12, attention should be paid to prevent the risk of embolism caused by thrombus embolization. The coaxiality of the suction catheter and the guide catheter should be maintained. The negative pressure should be maintained before the catheter is withdrawn, and the blood in the guide catheter should be sucked back to avoid thrombus embolization.

[0061] In the embodiment, the end of the suction tube 1 has a convex portion 13 and a concave portion 14, both of which are circular arc-shaped. The electrocoagulation assembly 7 includes electrocoagulation holes 15 arranged on the wall of the suction tube 1. The two electrocoagulation holes 15 are located at the position of the convex portion 13. A positive electrode 16 and a negative electrode 17 are respectively arranged in the two electrocoagulation holes 15. The positive electrode 16 and the negative electrode 17 are in gap cooperation with the electrocoagulation holes 15. The positive electrode 16 and the negative electrode 17 are connected with wires 26 and control devices. The control devices respectively apply positive charges and negative charges to the positive electrode 16 and the negative electrode 17 through the wires 26 and act on the wound, which is beneficial to rapid scabbing and hemostasis.

[0062] A barrier is arranged between the positive electrode 16 and the electrocoagulation hole 15, and between the negative electrode 17 and the electrocoagulation hole 15. The barrier can be made of elastic rubber, which not only seals the electrocoagulation hole 15, but also fixes the electrode. In one embodiment, the end of the positive electrode 16 and the negative electrode 17 is spherical. The positive electrode 16 and the negative electrode 17 are made of special metal to ensure good electrical conductivity and durability. Some high-quality electrodes can use gold material, which helps to avoid tissue adhesion and reduce the risk of heat damage to surrounding normal tissues. The use of the positive electrode 16 and the negative electrode 17 provides more accurate hemostasis effect and reduces damage to surrounding tissues. It is particularly suitable for use in neurosurgery, cerebral hemorrhage and other areas with high accuracy requirements. At the same time, the positive electrode 16 and the negative electrode 17 are installed in the wall of the suction tube 12, thereby canceling the buttock electrode and improving the operation precision and accuracy of electrocoagulation hemostasis.

[0063] Embodiment two

[0064] As Figure 3 , Figure 4As shown, the difference between the second embodiment and the first embodiment is that the suction tube 1 is provided with a flushing hole 18, and a flushing device is communicated with the flushing hole 18, and the flushing device sprays physiological saline or the like through the flushing hole 18 to the wound, which is beneficial to clean the wound, and the waste water generated by the flushing is discharged through the suction cavity 2. The bipolar electrocoagulation hemostasis is achieved by short-time discharge to rapidly increase the local temperature to about 80 degrees Celsius, which causes the intracellular water to rapidly evaporate, the blood vessels to shrink, and the collagen in the cells to coagulate, thereby achieving hemostasis. The physiological saline also serves to reduce the temperature to avoid tissue damage caused by overheating.

[0065] In one embodiment, the suction tube 1 is further provided with a mounting hole 19, and a scraper assembly 20 is mounted in the mounting hole 19. Specifically, the scraper assembly 20 includes a first scraper 21, a second scraper 22, a third scraper 23, and a fourth scraper 24 connected in sequence, and the first scraper 21, the second scraper 22, the third scraper 23, and the fourth scraper 24 are all made of elastic material. The first scraper 21 is connected with a connecting rod 25, and the end of the connecting rod 25 extends out of the mounting hole 19.

[0066] When the scraper assembly 20 is not used, it is retracted in the mounting hole 19, and when it is needed to be used, the connecting rod 25 pushes the scraper assembly 20 out of the mounting hole 19, so that the first scraper 21, the second scraper 22, the third scraper 23, and the fourth scraper 24 rebound to form a rectangular frame under the action of their own elasticity, and the side edges of the rectangular frame form scrapers. The side edge scrapers lightly scrape the wound by agitating the suction tube 1 or the connecting rod 25, crush the coagulated blood clots, clean them with the clean water sprayed through the flushing hole 18, and then discharge them out of the body through the suction cavity 2.

[0067] In the description of the present specification, the description of the terms "one embodiment", "some embodiments", "an example", "a specific example", or "some examples" and the like means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application.
