Description

Technical Field

[0001] The utility model relates to the technical field of laparoscopic surgery, in particular to a gastrointestinal lifting device for general surgical laparoscopy. Background Art

[0002] During laparoscopic surgery, in order to expose the surgical field and prevent the intestinal tract in the patient's body from affecting the medical staff's observation of the patient's abdominal cavity, it is necessary to use a gastrointestinal lifting device to lift and shift tubular internal organs such as the stomach, small intestine, and large intestine.

[0003] There are two types of gastrointestinal lifting devices at present. One is a negative pressure gastrointestinal lifting device, which uses a negative pressure suction cup to absorb and lift the stomach and intestines. However, since the surface of the stomach and intestines is relatively slippery, unstable adsorption is prone to occur, and the negative pressure is difficult to control accurately. Improper operation may cause damage to the stomach and intestines, so they are rarely used. The other is to use a lifting device similar to a lifting hook to lift and displace the stomach and intestines. For example, the existing patent with a publication number of CN213430299U discloses that it lifts the stomach and intestines by an arc rod similar to a lifting hook, but it lacks an anti-falling structure. In the process of lifting and moving the tubular viscera, the tubular viscera will slip off the lifting hook due to changes in gastrointestinal peristalsis, thereby causing damage to the tubular viscera.

Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more of the features; in the description of the utility model, unless otherwise specified, "plurality" means two or more.

[0021] Example 1

[0022] like Figures 1 to 3 As shown, an embodiment of the utility model provides a gastrointestinal lifting device for general surgical laparoscopy, comprising a lifting rod 1, a lifting ring 2 and an angle adjustment mechanism, the lifting ring 2 is vertically arranged below the lifting rod 1, and one side of the lifting ring 2 has an opening 21 for allowing tubular viscera to pass through; the angle adjustment mechanism is arranged between the lifting rod 1 and the lifting ring 2, and is used to adjust the angle of the opening 21, the angle adjustment mechanism comprises an arc-shaped slider 31, an arc-shaped slide groove 32, and a traction rope 33; the arc-shaped slider 31 is fixed to the lower end of the lifting rod 1; the arc-shaped slide groove 32 is arranged on the circumferential outer wall of the lifting ring 2, and the cross-section of the arc-shaped slide groove 32 is an inverted T-shape, the arc-shaped slider 31 is slidably connected in the large-diameter notch of the arc-shaped slide groove 32, and the arc-shaped slide groove 32 is coaxially arranged with the arc-shaped slider 31; one end of the traction rope 33 is connected to the upper end of the lifting ring 2 near its opening 21.

[0023] In this embodiment, when it is necessary to lift the tubular viscera during gastrointestinal laparoscopic surgery or other medical procedures, the tubular viscera to be lifted are first passed through the opening 21 into the lifting ring 2, and then the angle of the lifting ring 2 is adjusted by the angle adjustment mechanism, and the traction rope 33 is pulled upward to pull the lifting ring 2. Since the lifting ring 2 cooperates with the arc slider 31 through the arc slide groove 32, when the lifting ring 2 is pulled, the lifting ring 2 will rotate around the arc slider 31, so that the opening 21 is adjusted from horizontal to inclined upward, forming a limit and anti-detachment structure for the tubular viscera, and then the lifting rod 1 is moved to drive the lifting ring 2 to move to realize the process of lifting and moving the tubular viscera. Since the opening 21 is inclined upward during the movement, it can form a limit and anti-detachment structure for the tubular viscera, thereby avoiding the problem of the tubular viscera easily detaching from the lifting ring during the process of lifting and moving the tubular viscera.

[0024] Further, such as Figure 2 As shown, in order to enable the opening 21 to automatically return to a horizontal position from being tilted upward after the lifting is completed so as to remove the tubular viscera, a return spring 4 is provided in the arc-shaped slide groove 32, one end of the return spring 4 is connected to the side wall of the arc-shaped slider 31, and the other end of the return spring 4 is connected to the groove wall of the arc-shaped slide groove 32 close to the opening 21. The return spring 4 provided can automatically realize the process of resetting the position of the opening 21. When the traction rope 33 is pulled upward to make the lifting ring 2 rotate around the arc-shaped slider 31, the return spring 4 will be squeezed. When the traction rope 33 is released, the lifting ring 2 will automatically rotate in the opposite direction to the initial position under the action of the return spring 4, so that the opening 21 automatically returns to a horizontal position from being tilted upward.

[0025] Furthermore, Figure 3 As shown, in order to facilitate the operator to pull the traction rope 33, a traction mechanism is also included, which is used to pull the traction rope 33 to move. The traction mechanism includes a moving plate 51, a pulling portion 52, a fixed plate 53, a telescopic sleeve rod and a locking assembly 55; the moving plate 51 is slidably sleeved on the lifting rod 1, and the end of the traction rope 33 away from the lifting ring 2 is fixed to the lower end of the moving plate 51; the pulling portion 52 is fixed to the top of the moving plate 51; the fixed plate 53 is sleeved and fixed on the lifting rod 1, and is located directly below the moving plate 51 A slot 531 is provided on the fixed plate 53 for the traction rope 33 to pass through, and the traction rope 33 is inserted into the slot 531; the telescopic sleeve includes a fixed cylinder 541 and a movable column 542, the fixed cylinder 541 is fixed to the upper end of the fixed plate 53, one end of the movable column 542 is slidably sleeved in the fixed cylinder 541, and the other end of the movable column 542 is fixed to the bottom of the movable plate 51; the locking assembly 55 is arranged between the fixed cylinder 541 and the movable column 542, and is used to lock the moving position of the movable column 542.

[0026] When the operator pulls the traction rope 33 through the traction mechanism, the operator puts his finger on the pulling part 52 and uses the pulling part 52 to pull the movable plate 51 upward. During the movement of the movable plate 51, the traction rope 33 will be pulled to drive the lifting ring 2 to rotate. Through the provided telescopic sleeve rod, a limiting guiding effect on the movable plate 51 can be formed in the process of pulling the movable plate 51, so that the movable plate 51 can maintain vertical movement and prevent the movable plate 51 from rotating around the lifting rod 1. At the same time, the provided locking component 55 can lock the position of the movable column 542 when the movable plate 51 is pulled to a certain height by the pulling part 52, so that the opening 21 is adjusted from horizontal to inclined upward, thereby locking the height position of the traction rope driven by the movable plate 51 to rise, so as to keep the opening 21 always inclined upward during the lifting process. After the lifting is completed, the locking function of the locking component 55 on the moving position of the movable column 542 is released, and then the opening 21 is restored from inclined upward to horizontal under the reset of the reset spring 4.

[0027] Specifically, Figure 3 As shown, as a specific implementation of the locking component 55, the locking component 55 in this embodiment is an adjusting bolt, and a threaded hole is opened on the side wall of the fixed cylinder 541, and the adjusting bolt is threadedly connected to the threaded hole. When the movable column 542 is locked by the locking component 55, the adjusting bolt is tightened so that the end of the adjusting bolt is against the side wall of the movable column 542, and the movable column 542 is locked by friction. When the movable column 542 is unlocked by the locking component 55, it is only necessary to loosen the adjusting bolt, which is very convenient to operate.

[0028] Among them, as an optional implementation of the pulling portion 52, as Figure 3 As shown, the pulling portion 52 is a pull rod, which is fixed to the top of the movable plate 51. When in use, the operator pulls the pull rod with his fingers to drive the movable plate 51 to move.

[0029] Among them, as another optional implementation of the pulling part 52, the pulling part 52 is a pull ring (not shown in the figure), and the pull ring is fixed to the top of the movable plate 51. When in use, the operator pulls the pull ring by hand to drive the movable plate 51 to move. At the same time, compared with the pull rod, the pull ring also has the advantage of being able to prevent fingers from slipping and falling off.

[0030] Further, such as Figure 2 As shown, a through hole 22 for passing the traction rope 33 is provided at the upper end of the lifting ring 2 near its opening 21, and a drag rod 6 is fixed to the end of the traction rope 33 away from the movable plate 51 after passing through the through hole 22. The drag rod 6 is arranged so that when the traction rope 33 is pulled upward, the inner top surface of the lifting ring 2 at the opening 21 is dragged, thereby causing the lifting ring 2 to rotate around the arc-shaped slider 31.

[0031] Further, such as Figure 3 As shown, a mounting hole is opened on the movable plate 51, and a sliding sleeve 511 is fixed in the mounting hole. The sliding sleeve 511 is slidably mounted on the lifting rod 1. The setting of the sliding sleeve 511 can enable the movable plate 51 to move better along the longitudinal direction of the lifting rod 1, and the height of the sliding sleeve 511 can be set to be greater than the thickness of the movable plate 51, thereby avoiding the problem of deformation of the movable plate 51 due to its thin thickness during the process of pulling the movable plate 51.

[0032] In another embodiment of the present invention, in order to be able to automatically lift the lifting rod 1, an adjusting bracket and a lifting and lifting mechanism arranged on the adjusting bracket are also provided. Specifically, the lifting and lifting mechanism includes a bracket, a connecting seat 61, a first servo motor, a first screw 62 and a first nut seat 63. The connecting seat 61 is connected to the adjusting bracket. A vertical guide groove is provided on one side of the connecting seat 61. The first servo motor is fixed in the guide groove. The output shaft of the first servo motor is connected to the first screw 62. The first nut seat 63 is threadedly connected to the first screw 62, and the first nut seat 63 is slidably mounted in the guide groove. The end of the lifting rod 1 away from the lifting ring 2 is fixed to the first nut seat 63.

[0033] In this embodiment, the lifting and pulling mechanism is set up to automatically drive the lifting rod 1 to perform lifting and pulling. During lifting, the first servo motor is controlled to drive the first screw 62 to rotate. The rotation of the first screw 62 drives the first nut seat 63 to rise in the guide groove. During the movement of the first nut seat 63, the lifting rod 1 and the lifting ring 2 are driven to move vertically upward as a whole, thereby realizing the lifting and pulling process of the tubular internal organs.

[0034] Among them, in order to realize the lifting process of horizontal movement, a cross bar 71 is connected to the upper end of the adjusting bracket, and a mounting groove 72 is opened through the middle of the cross bar 71. A horizontally arranged second lead screw is arranged in the mounting groove 72, and one end of the second lead screw is rotatably connected to the mounting groove 72, and the other end of the second lead screw extends to the outside of the mounting groove 72 and is connected to a second servo motor 73. A second nut seat 74 is threadedly connected to the second lead screw, and the connecting seat 61 is fixed to the bottom of the second nut seat 74. The second servo motor 73 drives the second lead screw to rotate to drive the second nut seat 74 to move horizontally along the mounting groove 72. During the movement of the second nut seat 74, the connecting seat 61, the lifting and pulling mechanism, the lifting rod 1 and the lifting ring 2 are driven to move synchronously, thereby realizing the horizontal lifting and displacement operation of the tubular internal organs.

[0035] Specifically, the adjustment bracket includes a cylinder 81, the piston rod end of the cylinder 81 is fixedly connected to the cross bar 71, and the height of the cross bar 71 can be adjusted by the cylinder 81 to achieve preliminary adjustment of the initial height position of the pulling ring 2. At the same time, in order to ensure the vertical movement of the cross bar 71, vertically arranged limit plates 82 are fixedly connected to the two side walls of the cylinder body of the cylinder 1, and limit grooves 83 are penetrated on the side walls of the cross bar 71 facing the two limit plates 82, and the two limit plates 82 are slidably connected in the two limit grooves 83.

[0036] Furthermore, in order to facilitate the fixation of the adjusting bracket, a clamping and fixing mechanism is provided at the bottom of the cylinder 81, and the clamping and fixing mechanism includes a clamping seat 91 and a tightening bolt 92. The top of the clamping seat 91 is fixed to the bottom of the cylinder 81, and a side wall of the clamping seat 91 is provided with a clamping slot for clamping with the bed. The tightening bolt 92 is threadedly connected to the clamping seat 91, and the tightening bolt 92 is vertically arranged to the clamping slot. During installation, the clamping seat 91 is clamped to the bed through the clamping slot, and then the tightening bolt 92 is tightened. The friction force generated by the tightening bolt 92 on the bed part is clamped and fixed, thereby realizing the fixing process of the entire adjusting bracket.

[0037] The above disclosures are only several preferred specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
