Description

Technical Field

[0001] The present invention relates to the field of laparoscopes, and more specifically, to a negative pressure lifting gastrointestinal device for laparoscopic surgery. Background Art

[0002] Laparoscopic surgery is a minimally invasive surgical technique that operates by inserting a laparoscope and surgical instruments through small incisions. During laparoscopic surgery, organs such as the gastrointestinal tract may block the surgical area, affecting the vision. The lifting device temporarily fixes the gastrointestinal organs in a position that does not interfere with the surgery by lifting them, providing a clear operating field of vision for the doctor.

[0003] During laparoscopic surgery, when the laparoscope enters the patient's abdominal cavity, organs such as the patient's gastrointestinal tract may block the laparoscope, causing the laparoscope to be unable to observe the affected area, thereby affecting laparoscopic surgery. Traditionally, in the face of this situation, most often an assistant uses a retractor to reach into the patient's abdominal cavity and move it to push aside the patient's gastrointestinal organs, etc., so that the observation of the laparoscope is clearer. However, when this method is carried out, the cooperation between the assistant and the doctor requires extremely high tacit understanding, and during a long operation, it will also cause the assistant to be physically exhausted, resulting in situations such as the retractor shaking, which is likely to cause secondary harm to the patient. Summary of the Invention

[0012] Optionally, a locking member for changing the friction between the second support frame and the sliding bracket is also installed at the hinge joint between the sliding bracket and the second support frame. A connecting bracket is fixedly installed on one side of the sliding bracket. The fixed disk is fixedly installed at one end of the connecting bracket away from the sliding bracket.

[0032] As shown in the figure, in order to clearly implement the structure of the embodiments of the present invention, specific structures and devices are marked in the figure, but this is only for schematic needs and is not intended to limit the present invention to this specific structure, device, and environment. Those of ordinary skill in the art can adjust or modify these devices and environments according to specific needs. Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0034] Such as Figures 1 to 8As shown, an embodiment of the present invention provides a laparoscopic surgery negative pressure gastrointestinal lifting device, including a bottom seat plate 1, a pressure plate 11 is provided above the bottom seat plate 1, a negative pressure lifting member 5 for generating negative pressure to lift the patient's stomach and intestines is provided above the bottom seat plate 1, a first support frame 2 is provided on one side of the bottom seat plate 1, a sliding bracket 21 is provided on the middle sliding card of the first support frame 2, a second support frame 3 is hinged on the top end of the sliding bracket 21, a U-shaped bracket 31 is fixedly installed on the top end of the second support frame 3, an arc-shaped sliding rod 4 is provided on the middle sliding card of the U-shaped bracket 31, and the negative pressure lifting member 5 is fixedly installed on the end of the arc-shaped sliding rod 4 away from the U-shaped bracket 31.

[0035] During actual use, the patient is first allowed to lie flat on the pressure plate 11. At this time, the negative pressure lifting member 5 can project an indicator line on the patient's abdomen. The doctor makes an incision on the patient's abdomen through the indicator line, and then rotates the first support frame 2 to adjust the position of the negative pressure lifting member 5 and extend the negative pressure lifting member 5 into the patient's abdominal cavity. The negative pressure lifting member 5 can absorb the gastrointestinal tissue through negative pressure, and adjust the sliding bracket 21 to slide inside the first support frame 2, and then the height of the sliding bracket 21 can be changed so that the height of the negative pressure lifting member 5 is adjusted, thereby achieving precise lifting of the gastrointestinal tissue. Because the arc sliding rod 4 is arc-shaped, rotating the arc sliding rod 4 around the center point of the arc sliding rod 4 can adjust the negative pressure lifting member 5 in a horizontal position. At this time, the arc sliding rod 4 will slide along the U-shaped bracket, and by rotating the second support frame 3, the negative pressure lifting member 5 can be driven to move horizontally in another direction, so that the negative pressure lifting member 5 can accurately move in all directions, ensuring the flexibility and accuracy of the surgical operation.

[0036] The negative pressure lifting member 5 includes a connecting air cylinder 51, a lower end movable card of the connecting air cylinder 51 is provided with a toggle tube 53, a movable disk 54 is provided below the toggle tube 53, a second spherical part 541 is provided in the middle of the movable disk 54 through a ball and socket fitting card, a fixed disk 55 is provided below the movable disk 54, a first spherical part 56 is provided in the middle of the fixed disk 55 through a ball and socket fitting card, the toggle tube 53 passes through the second spherical part 541 and the first spherical part 56, and the toggle tube 53 is fixedly installed on the second spherical part 541, a rubber tube 531 and a rubber disk 532 are fixedly installed on the bottom end of the toggle tube 53, a plurality of evenly distributed connecting rods 57 are provided between the movable disk 54 and the fixed disk 55, and the two ends of the connecting rods 57 are respectively connected to the movable disk 54 and the fixed disk 55 through a ball and socket structure, a negative pressure pump 52 is fixedly installed on the top of the connecting air cylinder 51, and a laser marker 58 capable of emitting colored light beams is fixedly installed on the outer ring of the fixed disk 55.

[0037] The arc-shaped sliding rod 4 and the first spherical member 56 are arranged concentrically. The first spherical member 56 and the hinge of the connecting bracket 22 and the sliding bracket 21 are located on the same horizontal line. The first spherical member 56 and the center of the circular rotating plate 24 are located on the same vertical line.

[0038] After the abdominal incision of the patient is completed, the sliding bracket 21 is operated to slide along the inside of the first support frame 2 to reduce its height, which will drive the second support frame 3 and the negative pressure lifting member 5 to descend, so that the rubber cylinder 531 and the rubber disc 532 enter the patient's abdominal cavity. At this time, the negative pressure pump 52 can generate negative pressure, and the connecting air cylinder 51 transmits the negative pressure to the rubber cylinder 531 and the rubber disc 532 through the dialing tube 53, so as to adsorb the gastrointestinal tissue. When the arc-shaped sliding rod 4 rotates, because the arc-shaped sliding rod 4 and the first spherical member 56 are concentrically arranged, the connecting air cylinder 51 is driven to perform a circular motion at this time, and the dialing tube 53 is fixedly installed on the second spherical member 541. When the connecting air cylinder 51 moves, it will drive the second spherical member 541 to move. At this time, due to the ball socket structure between the second spherical member 541 and the moving disc 54, the moving disc 54 has a tendency to be driven to perform a circular motion, but because a plurality of connecting rods 57 are connected between the moving disc 54 and the fixed disc 55, the moving disc 54 is restricted to only perform horizontal movement. Therefore, when the connecting air cylinder 51 drives the dialing tube 53 to rotate, the moving disc 54 will be driven to move horizontally. When the rubber cylinder 531 enters the patient's abdominal cavity, the fixed disc 55 is closely attached to the patient's incision. Therefore, the swing of the dialing tube 53 will always swing around the first spherical member 56. No matter how the position of the negative pressure lifting member 5 is adjusted, the dialing tube 53 will always move around the first spherical member 56, preventing the incision position of the patient from being torn due to movement and avoiding secondary injury to the patient.

[0039] When the moving disc 54 moves horizontally, all the connecting rods 57 are driven to tilt. When the connecting rod 57 changes from vertical to tilted, according to the Pythagorean theorem, the distance between the moving disc 54 and the fixed disc 55 is shortened at this time. At this time, the relative movement between the dialing tube 53 and the first spherical member 56 occurs, that is, when the dialing tube 53 swings to a position away from the center of the circle, the length of the dialing tube 53 increases. When the moving disc 54 gradually moves back to its original position, the dialing tube 53 gradually returns to its original length, so that no matter how the moving disc 54 moves, the rubber disc 532 always moves on the same plane, preventing the device from pulling the gastrointestinal tissue that does not need to move during movement due to circular motion, ensuring the accuracy and safety of the surgical operation, and avoiding unnecessary tissue damage.

[0040] A first sliding groove 101 is formed in the middle of the bottom seat plate 1. Placement grooves 102 are formed on both the upper and lower sides of the first sliding groove 101. A third support frame 23 is fixedly installed at the bottom end of the first support frame 2. A circular rotating plate 24 is fixedly installed at one end of the third support frame 23 away from the first support frame 2. The circular rotating plate 24 is located inside the first sliding groove 101. A square sliding block 25 is rotatably clamped in the middle of the circular rotating plate 24. The square sliding block 25 is slidably clamped inside the placement groove 102. A second corrugated plate 251 is provided on the upper surface of the square sliding block 25. A plurality of uniformly distributed stabilizing rods 111 are fixedly installed on the lower surface of the pressing plate 11. The stabilizing rods 111 are slidably clamped on the upper surface of the bottom seat plate 1. A first corrugated plate 112 is fixedly installed at a position corresponding to the placement groove 102 on the lower surface of the pressing plate 11. A plurality of uniformly distributed first springs 113 are fixedly connected between the pressing plate 11 and the bottom seat plate 1. The first springs 113 are sleeved outside the stabilizing rods 111.

[0041] Because the body shapes of patients are different, the incision positions of patients are also different. Therefore, when the patient has not yet lain on the pressing plate 11, the pressing plate 11 is pushed by the first spring 113 to separate from the bottom seat plate 1. At this time, the first corrugated plate 112 is separated from the second corrugated plate 251, and the square sliding block 25 can slide along the inside of the placement groove 102, so that the positions of the third support frame 23 and the first support frame 2 can be changed, and then the horizontal position of the negative pressure lifting member 5 can be changed to facilitate adaptation to different patients. When it is moved to a suitable position, let the patient lie on the pressing plate 11. At this time, under the weight of the patient, the pressing plate 11 is pressed to closely fit with the bottom seat plate 1. At this time, the first corrugated plate 112 contacts the second corrugated plate 251 again, locking the position of the square sliding block 25.

[0042] A second sliding groove 231 is formed in the middle of the third support frame 23. A central sliding block 27 is slidably clamped inside the second sliding groove 231. Limiting plates 26 are rotatably installed at both the upper and lower ends of the central sliding block 27. A second spring 232 is fixedly connected between the central sliding block 27 and the second sliding groove 231. The limiting plates 26 and the central sliding block 27 are fixed by a locking member 6.

[0043] When the circular rotating plate 24 rotates, the limiting plates 26 will be blocked by the side of the bottom seat plate 1. Under the push of the second spring 232, the two limiting plates 26 will closely fit with the side of the bottom seat plate 1. When the circular rotating plate 24 rotates to a suitable position, the locking member 6 can be tightened so that the limiting plates 26 and the central sliding block 27 cannot move relative to each other, for limiting the angle of the circular rotating plate 24.

[0044] A locking member 6 for changing the friction force between the second support frame 3 and the sliding support 21 is also installed at the hinge joint between the sliding support 21 and the second support frame 3. A connecting bracket 22 is fixedly installed on one side of the sliding support 21. The fixed disk 55 is fixedly installed at the end of the connecting bracket 22 away from the sliding support 21. A locking member 6 for changing the position of the sliding support 21 is also fixedly connected between the sliding support 21 and the first support frame 2. The locking member 6 includes a screw handle 61, and a mating sleeve 62 is sleeved at the bottom end of the screw handle 61 through thread fit.

[0045] The locking member 6 at the hinge joint between the sliding support 21 and the second support frame 3 can adjust the friction force to ensure that the sliding support 21 and the second support frame 3 are stably fixed at a specific angle. The locking member 6 between the sliding support 21 and the first support frame 2 is used to lock the positions of the sliding support 21 and the first support frame 2. When locking, only need to rotate the screw handle 61 to reduce the distance between the screw handle 61 and the mating sleeve 62 to lock.

[0046] A stabilizing sleeve 311 is fixedly installed at the position corresponding to the arc-shaped sliding rod 4 in the middle of the U-shaped bracket 31. The arc-shaped sliding rod 4 is slidably clamped inside the stabilizing sleeve 311. A locking screw 32 is clamped at the end of the U-shaped bracket 31 away from the second support frame 3 through thread fit. A rubber slider 33 is rotatably installed at the end of the locking screw 32. The rubber slider 33 is slidably clamped inside the U-shaped bracket 31.

[0047] Rotating the locking screw 32 can change the position of the rubber slider 33. One side of the rubber slider 33 is made of rubber. The locking screw 32 presses the rubber slider 33 against one side of the stabilizing sleeve 311, and then can lock the arc-shaped sliding rod 4 and change the tightness of the arc-shaped sliding rod 4, which is convenient for fixing and adjusting.

[0048] The above is only the preferred specific implementation manner of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improvement concept, makes equivalent substitution or change, and should be covered by the protection scope of the present invention.
