Description

Technical Field

[0001] The utility model relates to the field of catheter fixing, in particular to a catheter fixing frame for surgical nursing. Background Art

[0002] As we all know, common techniques such as laparoscopic surgery, which use a thin catheter to insert into the abdominal wall of the human body, can provide feasible operating space for the laparoscope and surgical instruments. Therefore, catheter interventional therapy, as a commonly used medical method in clinical gastrointestinal surgery, is the basic technical prerequisite for minimally invasive gastrointestinal surgery.

[0003] In actual use, interventional catheters need to be kept in the same position for a long time, which puts higher requirements on the stability and reliability of the catheter fixing device. For example, the prior art CN217612429U discloses a catheter fixing frame for gastrointestinal surgical nursing, including a support cabinet, the lower surface of which is fixedly connected with a universal wheel, and the inner bottom wall of the support cabinet is fixedly placed with a disinfection cabinet; the catheter can be effectively fixed by the clamping piece.

[0004] However, the prior art still needs to use a clamping piece to clamp and fix the catheter. After the catheter is clamped on both sides, it is easy to cause the catheter to be squeezed and deformed, which will affect the normal use of the catheter. In addition, sufficient clamping force is usually required to clamp it. Even if it is not deformed, it will cause a large squeezing impact on the catheter, which may easily cause damage to the catheter in the long run. In order to avoid the above defects, the utility model provides a catheter fixing frame for surgical nursing. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-4 A catheter fixing frame for surgical care includes a lifting motor 2 fixedly mounted on a surgical care vehicle 1, a frame 3 fixedly mounted on the output end of the lifting motor 2, and a plurality of support tubes 4 fixedly mounted on the frame 3; an arc-shaped positioning airbag 6 for negative pressure positioning of a catheter 7 is provided on the inner side of the support tube 4;

[0025] The two arc-shaped positioning airbags 6 are fixedly connected to the movable block 5 on the side away from each other, and the inner walls on both sides of the support tube 4 are provided with through holes 401, and the movable block 5 slides in the horizontal direction to the outside of the through holes 401; the movable block 5 is provided with a negative pressure mechanism for sucking air into the arc-shaped positioning airbag 6 and generating negative pressure, and the arc-shaped positioning airbag 6 uses the negative pressure generated by the negative pressure mechanism to negatively pressure adsorb and position the two sides of the catheter 7;

[0026] A guide slider 402 is fixedly connected to the top inner wall and the bottom inner wall of the through hole 401, a guide slot 11 is symmetrically provided on the movable block 5, and the guide slider 402 is slidably installed in the guide slot 11 along the horizontal direction; a first electromagnet 8 is fixedly connected to the right side of the guide slider 402, and a second electromagnet 9 is fixedly connected to the right inner wall of the guide slot 11, and the magnetic directions generated by the first electromagnet 8 and the second electromagnet 9 are set in opposite directions after power is turned on.

[0027] In this example, the negative pressure mechanism includes a piston chamber 501 arranged on the movable block 5, a piston 503 is movably arranged in the piston chamber 501, an electric telescopic rod 502 is fixedly installed on the left inner wall of the piston chamber 501, and the output end of the electric telescopic rod 502 is fixedly connected to the piston 503; a negative pressure suction tube 504 is also connected between the piston chamber 501 and the arc-shaped positioning airbag 6.

[0028] In this example, the negative pressure mechanism also includes an air suction one-way solenoid valve 505 arranged on the negative pressure suction pipe 504; an exhaust pipe 506 is also connected to the right inner wall of the piston chamber 501, and the other end of the exhaust pipe 506 extends to the outside of the movable block 5 and is fixedly connected to an exhaust one-way solenoid valve 507.

[0029] In this example, the negative pressure mechanism further includes a plurality of negative pressure positioning holes 601 disposed inside the two arc-shaped positioning airbags 6, and the plurality of negative pressure positioning holes 601 are evenly and equidistantly arranged.

[0030] In this example, a guide slide bar 10 is fixedly installed in the guide slide groove 11, a guide slide hole is provided on the guide slide block 402, and the guide slide block 402 is slidably sleeved on the guide slide bar 10 along the horizontal direction through the guide slide hole.

[0031] Among them, casters are arranged on the bottom side of the surgical nursing cart 1; a controller is also arranged on the front side of the surgical nursing cart 1, and the controller is electrically controlled and connected with the lifting motor 2, the electric telescopic rod 502, the first electromagnet 8, the second electromagnet 9, the suction one-way solenoid valve 505, and the exhaust one-way solenoid valve 507 respectively.

[0032] like Figure 1-4As shown, the utility model provides a catheter fixing frame for surgical care. During use, by setting a negative pressure mechanism, the arc-shaped positioning airbags 6 on both sides can negatively pressure adsorb and position the catheter 7 through the negative pressure positioning hole 601; when not positioned, the catheter 7 can be moved inside the support tube 4, so that the position of the catheter 7 can be adjusted. After adjusting to the required position, it can be negatively pressure positioned and fixed by the arc-shaped positioning airbags 6. That is, when the negative pressure is positioned and fixed: first, the first electromagnet 8 and the second electromagnet 8 are energized through the controller. Since the magnetic directions generated by the first electromagnet 8 and the second electromagnet 9 after being energized are set in opposite directions, and according to the principle that the same magnetic poles repel each other, the first electromagnet 8 can generate a reverse magnetic repulsive force on the second electromagnet 9 after being energized, so that the second electromagnet 9 can move to the right. When the second electromagnet 9 moves to the right, it drives the movable block 5 and the arc-shaped positioning airbag 6 to move to the right, so that the arc-shaped positioning airbag 6 moves to contact the outer wall of the catheter 7; then, the electric telescopic rod 502 in the negative pressure mechanism pushes the piston 503 to move left and right in the piston chamber 504; When the piston 503 moves to the left, negative pressure is generated in the right space of the piston chamber 504, which in turn prompts the suction one-way solenoid valve 505 on the negative pressure suction pipe 504 to open, so that negative pressure can be generated in the arc-shaped positioning airbag 6; when the piston 503 moves to the right, the pressure in the right space of the piston chamber 504 increases, which in turn prompts the exhaust one-way solenoid valve 507 on the exhaust pipe 506 to open, so that the piston chamber 504 is exhausted; in this way, through the above-mentioned operations, negative pressure can be continuously generated in the arc-shaped positioning airbag 6, and then the arc-shaped positioning airbag 6 can negatively adsorb and position the catheter 7 through the negative pressure positioning hole 601, so that the catheter 7 can be stably positioned. Finally, the first electromagnet 8 and the second electromagnet 9 are powered off to make their magnetism disappear. In this way, the arc-shaped positioning airbag 6 is prevented from generating a clamping force on the catheter 7. Finally, the catheter 7 is fixed by negative pressure only through the negative pressure in the arc-shaped positioning airbags 6 on both sides. This avoids the situation in which the catheter is squeezed and deformed due to the use of clamping plates to clamp and fix the catheter in the prior art, thereby greatly ensuring the normal use of the catheter and avoiding the disadvantage of the prior art that the catheter is squeezed and clamped, which is easy to cause damage to the catheter, which is beneficial to ensuring the service life of the catheter.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
