Description

Technical Field

[0001] The present invention relates to the technical field of abdominal drainage equipment, and in particular to a percutaneous visual abdominal exploration and precise drainage equipment under the guidance of an endoscope. Background Art

[0002] Abdominal surgery refers to the process of entering the abdominal cavity through surgery to diagnose, treat or repair organs or tissues in the abdominal cavity. This surgery can be performed through traditional open surgery or more minimally invasive laparoscopic surgery. Abdominal drainage refers to the placement of drainage tubes to drain fluid, pus, blood and other fluids in the abdominal cavity, thereby reducing pressure and fluid accumulation in the abdominal cavity and preventing complications.

[0003] However, the current bedside abdominal drainage tube equipment is often placed blindly, and the actual position of the catheter tip cannot be seen, so the local lesion cannot be accurately located. Therefore, most surgical operations are now performed by laparotomy, which causes greater surgical trauma. In addition, the current abdominal drainage tube equipment cannot achieve visual flushing and drainage, which can easily cause drainage deviations. Summary of the invention

[0024] Specifically, a first fixed port 12 is provided on the top of the drainage tube 11 , and the data line 14 is provided in the first fixed port 12 .

[0025] In the above technical solution, the first fixed port 12 is used to fix the data line 14, thereby preventing the normal use of the drainage tube 11 from being affected by the looseness of the data line 14 during use.

[0026] Specifically, a connector 22 is provided on the end surface of the injection tube 21 away from the drainage tube 11 , a connecting tube 23 is provided on the connecting tube 22 , and a syringe 24 is provided on the connecting tube 23 .

[0027] In the above technical solution, by using the syringe 24, the liquid medicine can flow into the patient's body along the connecting tube 23, the liquid inlet tube and the drainage tube 11 with the help of the pressure of the syringe 24, thereby making it convenient for medical staff to flush the patient.

[0028] Specifically, a sealing ring is provided between the connecting head 22 and the connecting pipe 23, and the sealing ring is made of rubber.

[0030] Specifically, a second fixed port 32 is provided on an end surface of the discharge pipe 31 away from the drainage pipe 11 , and a waste liquid bag is provided on the second fixed port 32 .

[0031] In the above technical solution, after flushing the wound area of ​​the patient, the negative pressure of the waste liquid bag is used to enable the flushed medicine liquid to flow along the drainage tube 11 and the discharge tube 31 under the action of negative pressure, and then flow into the waste liquid bag, thereby achieving the effect of recovering the flushed medicine liquid.

[0032] Specifically, a protective head 16 is threadedly provided on the bottom end surface of the drainage tube 11, and the protective head 16 is made of rubber.

[0033] In the above technical solution, by using the protective head 16 made of relatively soft material, the flexibility of the end face of the drainage tube 11 can be improved, and the situation in which the drainage tube 11 is scratched on the wound when passing through the micro-wound due to the relatively hard end of the drainage tube 11, thereby causing secondary damage to the wound, can be avoided as much as possible.

[0034] Specifically, a protective cover 17 is disposed inside the protective head 16 . The protective cover 17 is snap-fitted onto the bottom end surface of the data cable 14 , and the camera 15 is disposed inside the protective cover 17 .

[0035] In the above technical solution, by utilizing the protective cover 17 , the camera 15 can be protected.

[0036] During abdominal surgery, the display screen 42 is irradiated by light in the operating room, so that the display screen 42 is directly irradiated by the light, which may easily cause the display screen 42 to become blurred. Therefore, due to the blurriness of the display screen 42, the medical staff cannot clearly and effectively view the patient's abdominal cavity through the display screen 42. Therefore, the medical staff is required to adjust the angle of the display screen 42 so that the medical staff can effectively view the display screen 42. However, in the prior art, since the medical staff needs to operate the drainage tube 11 with one hand, it is not convenient for the other hand holding the handle 41 to adjust the angle of the display screen 42 with one hand, which affects the abdominal surgery operation.

[0037] Specifically, the adjustment mechanism 5 includes a fixed seat 501 fixedly mounted on the top of the handle 41, a support plate 502 fixedly mounted on the top surface of the fixed seat 501, a worm 503 rotatably mounted on the support plate 502, and a first bevel gear 504 fixedly mounted on one end of the worm 503; a first rotating rod 505 rotatably mounted on the fixed seat 501, a second bevel gear 506 meshing with the first bevel gear 504 fixedly mounted on the top of the first rotating rod 505, and a second bevel gear 506 meshing with the first bevel gear 504 is fixedly mounted on the bottom end of the first rotating rod 505. A first circular gear 507 is fixedly installed, and a first gear plate 508 meshing with the first circular gear 507 is rotatably arranged on the circumferential surface of the handle 41; a rotating frame 509 is also rotatably arranged on the support plate 502, and a rotating shaft 510 is rotatably arranged on the rotating frame 509, and a worm wheel 511 matching with the worm 503 is fixedly installed on the circumferential surface of the rotating shaft 510; mounting frames 512 are rotatably installed on the end surfaces of both ends of the rotating shaft 510, and the mounting frames 512 are fixedly installed on the bottom end of the display screen 42.

[0038] Furthermore, a second rotating rod 513 is rotatably provided on the fixed seat 501, a third bevel gear 514 is fixedly installed on the top end of the second rotating rod 513, and a fourth bevel gear 515 meshing with the third bevel gear 514 is fixedly installed on the side wall of the rotating frame 509; a second circular gear 516 is fixedly installed on the bottom end of the second rotating rod 513, and a second gear plate 517 meshing with the second circular gear 516 is also rotatably provided on the circumferential surface of the handle 41.

[0039] In the above technical solution, the first gear plate 508 is used, and the first round gear 507 on the first rotating rod 505 is used to cooperate with each other, so that the second bevel gear 506 on the first rotating rod 505 is rotated, and the worm 503 on the supporting plate 502 is rotated by using the mutual cooperation between the first bevel gear 504 and the second bevel gear 506, and the display screen 42 can be swung left and right by remembering the mutual cooperation between the worm 503 and the worm wheel 511; By utilizing the second gear plate 517 and cooperating with the second circular gear 516 on the second rotating rod 513, the fourth bevel gear 515 on the second rotating rod 513 is rotated, and by utilizing the mutual cooperation between the third bevel gear 514 and the fourth bevel gear 515, the rotating frame 509 on the supporting plate 502 is rotated, so that the display screen 42 can swing back and forth; Therefore, through the cooperation between the above structures, medical staff can adjust the angle of the display screen 42 on the handle 41 with only one hand, thereby improving the convenience of the display screen 42.

[0040] Specifically, a first knob 518 and a second knob 519 are rotatably provided on the circumference of the handle 41 . The first knob 518 and the second knob 519 are fixedly connected to the first gear plate 508 and the second gear plate 517 respectively, and the second knob 519 is rotatably sleeved on the first knob 518 .

[0041] In the above technical solution, by using the first knob 518 and the second knob 519, the first gear plate 508 and the second gear plate 517 can be easily operated to rotate.

[0042] Working principle: After a minimally invasive opening is made in the patient's abdominal cavity, the drainage tube 11 is used to extend into the patient's abdominal cavity through the minimally invasive opening, and the information spied on by the camera 15 is fed back to the display screen 42 through the data line 14 by the display mechanism 4, so that the medical staff can peek into the patient's abdominal cavity; When it is necessary to clean the patient's abdominal wound, the syringe 24 is used to make the liquid medicine flow into the patient's body along the connecting tube 23, the liquid inlet tube and the drainage tube 11 by pressing the syringe 24, so that the medical staff can flush the patient's abdominal cavity. After flushing the patient's wound, the liquid medicine after flushing can flow along the drainage tube 11 and the liquid discharge tube 31 under the action of negative pressure by using the negative pressure of the waste liquid bag, and then flow into the waste liquid bag, and then the liquid medicine after flushing can be recovered. When the angle of the display screen 42 on the handle 41 needs to be adjusted, the first gear plate 508 is used, and the first circular gear 507 on the first rotating rod 505 cooperates with each other, so that the second bevel gear 506 on the first rotating rod 505 rotates, and the first bevel gear 504 and the second bevel gear 506 cooperate with each other, so that the worm 503 on the support plate 502 rotates, and the display screen 42 can be swung left and right by remembering the cooperation between the worm 503 and the worm wheel 511; The disk 517, and through the mutual cooperation with the second circular gear 516 on the second rotating rod 513, the fourth bevel gear 515 on the second rotating rod 513 is rotated, and through the mutual cooperation between the third bevel gear 514 and the fourth bevel gear 515, the rotating frame 509 on the support plate 502 is rotated, so that the display screen 42 can swing back and forth; therefore, through the mutual cooperation between the above-mentioned structures, the medical staff only needs one hand to adjust the angle of the display screen 42 on the handle 41, thereby improving the convenience of the display screen 42. The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
