[0032] As shown in the figure, in order to clearly realize the structure of the embodiments of the application, specific structures and devices are marked in the figure, but this is only for the need of illustration, and is not intended to limit the application in the specific structure, device and environment, and those skilled in the art can adjust or modify these devices and environment according to specific needs. DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the application; obviously, the described embodiments are only part of the embodiments of the application, not all the embodiments, and all other embodiments obtained by those skilled in the art without creative labor based on the embodiments in the application belong to the protection scope of the application.

[0034] As Figures 1 to 8As shown, the embodiment of the present application provides a laparoscopic surgery negative pressure lifting gastrointestinal device, which comprises a bottom seat plate 1, a pressing plate 11 arranged above the bottom seat plate 1, a negative pressure lifting piece 5 for generating negative pressure to lift the patient's intestines and stomach, a first support frame 2 arranged on one side of the bottom seat plate 1, a sliding support 21 slidably arranged in the middle of the first support frame 2, a second support frame 3 hingedly arranged at the top end of the sliding support 21, a U-shaped support 31 fixedly arranged at the top end of the second support frame 3, an arc-shaped sliding rod 4 slidably arranged in the middle of the U-shaped support 31, and the negative pressure lifting piece 5 is fixedly arranged at one end of the arc-shaped sliding rod 4 away from the U-shaped support 31.

[0035] In actual use, first, let the patient lie on the pressing plate 11, at this time the negative pressure lifting piece 5 can project an indication line on the patient's abdomen, the doctor makes an incision on the patient's abdomen according to the indication line, then rotates the first support frame 2 to adjust the position of the negative pressure lifting piece 5, and the negative pressure lifting piece 5 is inserted into the patient's abdominal cavity, the negative pressure lifting piece 5 can adsorb the gastrointestinal tissue through negative pressure, the sliding support 21 is adjusted to slide in the first support frame 2, and then the height of the sliding support 21 is changed so that the height of the negative pressure lifting piece 5 is adjusted, thereby realizing accurate lifting of the gastrointestinal tissue, because the arc-shaped sliding rod 4 is arc-shaped, rotating the arc-shaped sliding rod 4 around the center point of the arc-shaped sliding rod 4 can adjust the horizontal position of the negative pressure lifting piece 5, at this time the arc-shaped sliding rod 4 will slide along the U-shaped support, and rotating the second support frame 3 can drive the negative pressure lifting piece 5 to move horizontally in another direction, so that the negative pressure lifting piece 5 can accurately move in all directions, ensuring the flexibility and accuracy of the operation.

[0036] The negative pressure lifting piece 5 comprises a connecting air cylinder 51, a push pipe 53 movably arranged at the lower end of the connecting air cylinder 51, a moving disc 54 arranged below the push pipe 53, a second spherical piece 541 arranged in the middle of the moving disc 54 through ball socket cooperation, a fixed disc 55 arranged below the moving disc 54, a first spherical piece 56 arranged in the middle of the fixed disc 55 through ball socket cooperation, the push pipe 53 penetrating the second spherical piece 541 and the first spherical piece 56, and the push pipe 53 is fixedly arranged on the second spherical piece 541, a rubber cylinder 531 and a rubber disc 532 fixedly arranged at the bottom end of the push pipe 53, a plurality of connecting rods 57 evenly distributed between the moving disc 54 and the fixed disc 55, the two ends of the connecting rod 57 being connected to the moving disc 54 and the fixed disc 55 through ball socket structures, a negative pressure pump 52 fixedly arranged at the top end of the connecting air cylinder 51, and a laser marker 58 capable of emitting colored light beams fixedly arranged at the outer ring of the fixed disc 55.

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

[0038] When the abdominal incision of the patient is completed, the sliding support 21 is operated to slide along the interior of the first support frame 2 and to lower its height, which drives the second support frame 3 and the negative pressure lifting piece 5 to descend, so that the rubber cylinder 531 and the rubber disc 532 enter the abdominal cavity of the patient, at this time the negative pressure pump 52 can generate negative pressure, the connecting air cylinder 51 transmits the negative pressure to the rubber cylinder 531 and the rubber disc 532 through the poking pipe 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 part 56 are concentrically arranged, at this time the connecting air cylinder 51 is driven to move in a circle, and the poking pipe 53 is fixedly installed on the second spherical part 541, when the connecting air cylinder 51 moves, the second spherical part 541 is driven to move, at this time, because of the ball-and-socket structure between the second spherical part 541 and the moving disc 54, the moving disc 54 has a tendency to move in a circle, 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 limited to move horizontally, so that when the connecting air cylinder 51 drives the poking pipe 53 to rotate, the moving disc 54 moves horizontally, when the rubber cylinder 531 enters the interior of the abdominal cavity of the patient, the fixed disc 55 is tightly attached to the incision of the patient, so that the swinging of the poking pipe 53 is always centered on the first spherical part 56, no matter how the position of the negative pressure lifting piece 5 is adjusted, the poking pipe 53 always moves with the first spherical part 56 as the center, which prevents the incision position of the patient from being torn due to movement, and the secondary injury to the patient.

[0039] When the moving disc 54 moves horizontally, at this time all the connecting rods 57 are driven to incline, when the connecting rods 57 change from being vertical to being inclined, 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 poking pipe 53 moves relative to the first spherical part 56, that is, when the poking pipe 53 swings away from the center position, the length of the poking pipe 53 increases, when the moving disc 54 gradually moves back to the original position, at this time the length of the poking pipe 53 gradually returns to the original length, so that no matter how the moving disc 54 moves, the rubber disc 532 always moves on the same plane, which prevents the device from pulling the gastrointestinal tissue that does not need to be moved due to circular motion, ensures the precision and safety of the operation, and avoids unnecessary tissue damage.

[0040] The middle part of the bottom seat plate 1 is provided with a first sliding groove 101, and the upper and lower sides of the first sliding groove 101 are provided with a placing groove 102. The bottom end of the first supporting frame 2 is fixedly installed with a third supporting frame 23, and the end away from the first supporting frame 2 of the third supporting frame 23 is fixedly installed with a circular rotating plate 24.

The lower surface of the pressing plate 11 is fixedly installed with a plurality of evenly distributed stabilizing rods 111 which are slidably clamped on the upper surface of the bottom seat plate 1. The lower surface of the pressing plate 11 is fixedly installed with a first corrugated plate 112 at the position corresponding to the placing groove 102. A plurality of evenly distributed first springs 113 are fixedly connected between the pressing plate 11 and the bottom seat plate 1, and the first springs 113 are sleeved on the outside of the stabilizing rods 111.

[0041] Because the body types of patients are different, the incision positions of patients are also different, and then when the patient has not yet lain on the pressing plate 11, the pressing plate 11 is pushed away from the bottom seat plate 1 by the first springs 113. 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 placing groove 102, so as to change the positions of the third supporting frame 23 and the first supporting frame 2, and then change the horizontal position of the negative pressure lifting piece 5, so as to adapt to different patients. When moving to the appropriate position, the patient lies on the pressing plate 11, and at this time the pressing plate 11 is pressed to be closely attached to the bottom seat plate 1 under the weight of the patient. At this time, the first corrugated plate 112 recontacts the second corrugated plate 251, and the position of the square sliding block 25 is locked.

[0042] The middle part of the third supporting frame 23 is provided with a second sliding groove 231, and the inside of the second sliding groove 231 is slidably clamped with a center sliding block 27.

Under the pushing of the second spring 232, the two limiting plates 26 will be closely attached to the side edge of the bottom seat plate 1. When the circular rotating plate 24 rotates to the appropriate position, the locking piece 6 can be tightened, so that the limiting plate 26 and the center sliding block 27 cannot relatively move, and the angle of the circular rotating plate 24 is limited.

[0044] The hinged joint of the sliding support 21 and the second support frame 3 is also provided with a locking piece 6 for changing the friction between the second support frame 3 and the sliding support 21, and one side of the sliding support 21 is fixedly provided with a connecting support 22, and a fixed disc 55 is fixedly arranged at the end of the connecting support 22 away from the sliding support 21, and the locking piece 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, and the locking piece 6 comprises a screw knob 61, and the bottom end of the screw knob 61 is sleeved with a matched sleeve 62 through thread cooperation.

[0045] The locking piece 6 at the hinged joint of the sliding support 21 and the second support frame 3 can adjust the friction size, and ensure that the sliding support 21 and the second support frame 3 are stably fixed at a specific angle, and the locking piece 6 between the sliding support 21 and the first support frame 2 is used for locking the position of the sliding support 21 and the first support frame 2, and only needs to rotate the screw knob 61 to reduce the distance between the screw knob 61 and the matched sleeve 62 to lock.
