Description

Technical Field

[0002] For traditional thoracotomy, the doctor needs to make an incision of 15 to 20 cm, or even larger than 20 cm, on the patient's chest wall, and also spread the ribs. The doctor performs the surgery through this large incision under direct vision, and the operation is performed by inserting instruments with both hands. Existing laparoscopic surgery only requires 1 to 3 1.5 cm small holes to be opened on the patient's chest wall, and the laparoscope and surgical instruments are inserted into the patient's chest cavity through the small holes. The laparoscope replaces the doctor's eyes, and the tiny medical camera on the laparoscope can project the situation in the chest cavity onto a large display screen. The doctor then performs the corresponding surgical operation with the surgical instruments inserted into the chest cavity. Existing laparoscopy is usually fixed in position by hand, which puts a heavy burden on the surgeon and cannot be kept fixed and stable.

The first handle bolt 102 is arranged to cooperate with the anti-sliding block 103. When the high-stability support device for laparoscopic surgery needs to be fixed, it is only necessary to rotate the first handle bolt 102 so that the anti-sliding block 103 contacts the ground.

[0065] The clamping structure 7 can clamp and fix the laparoscope bodies 9 of different sizes;

[0066] The lifting mechanism 2 is used to preliminarily adjust the height of the laparoscope body 9, and the lifting mechanism 2 is installed on the base 1 through the shock absorbing mechanism 3;

[0067] The length adjustment mechanism 4 is arranged at the upper end of the lifting mechanism 2, and the length adjustment mechanism 4 is used to adjust the height of the laparoscope body 9 and the distance between the laparoscope body 9 and the patient;

[0068] The horizontal rotating mechanism 5 is installed at one end of the length adjusting mechanism 4 away from the lifting mechanism 2, and the horizontal rotating mechanism 5 is used to adjust the horizontal direction of the laparoscope body 9;

[0069] The longitudinal rotation mechanism 6 is installed on the horizontal rotation mechanism 5 , and the longitudinal rotation mechanism 6 is used to adjust the longitudinal angle of the laparoscope body 9 .

[0070] In this embodiment, the lifting mechanism 2 includes a cylindrical barrel 201 and a lifting rod 202. The lower end of the lifting rod 202 is slidably inserted into the interior of the cylindrical barrel 201. The upper end of the cylindrical barrel 201 is threadedly rotatably connected with a second handle bolt 203 for fixing the lifting rod 202 inside the cylindrical barrel 201.

[0071] The length adjustment mechanism 4 includes a first adjustment rod 401 and a second adjustment rod 402. One end of the first adjustment rod 401 is connected to the upper end of the lifting rod 202 through a first joint 8a, and one end of the first adjustment rod 401 away from the lifting rod 202 is connected to one end of the second adjustment rod 402 through a second joint 8b.

[0072] The horizontal rotation mechanism 5 includes an L-shaped rod 501, the upper end of which is connected to an end of the second adjustment rod 402 away from the first adjustment rod 401 through a third joint 8c;

[0073] The longitudinal rotation mechanism 6 includes a cross bar 601 , which is connected to an end of the L-shaped rod 501 away from the second adjustment rod 402 via a fourth joint 8 d .

[0074] The first joint 8a, the second joint 8b, the third joint 8c and the fourth joint 8d are all configured as locking joint components, which include a cylinder 801, an electromagnet 805 is fixedly installed on the inner top of the cylinder 801, a rotating toothed disc 802 is rotatably connected to the inner bottom of the cylinder 801, a movable toothed disc 803 is arranged inside the cylinder 801, and the movable toothed disc 803 is located between the electromagnet 805 and the rotating toothed disc 802, and a spring 804 is arranged inside the cylinder 801, and the top of the spring 804 is pressed against the rotating toothed disc 802. At the inner top of the cylinder 801, the bottom of the spring 804 is pressed on the bottom of the movable toothed disc 803. Under the elastic force of the spring 804, the tooth head at the bottom of the movable toothed disc 803 can be inserted into the tooth groove at the top of the movable toothed disc 803. The top of the cylinder 801 is fixedly connected with a first flange 806 for connection, and the bottom of the rotating toothed disc 802 is fixedly connected with a connecting shaft 8a0. The connecting shaft 8a0 rotates through the bottom of the cylinder 801 through a bearing and is fixedly connected with a second flange 807 for connection.

[0075] The inner wall of the cylinder 801 is provided with a limit slide groove 8011, and the side of the movable toothed disc 803 is fixedly connected to a limit slide block 8031, and the limit slide block 8031 ​​is slidably disposed in the limit slide groove 8011;

[0076] When the electromagnet 805 is energized, the movable toothed disc 803 is attracted by the magnetic force generated by the electromagnet 805 and moves upward, so that the tooth head at the bottom of the movable toothed disc 803 moves out of the tooth groove at the top of the rotating toothed disc 802, so that the movable toothed disc 803 can rotate;

[0077] When the electromagnet 805 is powered off, the movable toothed disc 803 moves downward again under the elastic force of the spring 804, so that the tooth head at the bottom of the movable toothed disc 803 is stuck in the tooth groove at the top of the movable toothed disc 803;

[0078] The first flange 806 on the first joint 8a is fixedly connected to the upper end of the lifting rod 202, and the second flange 807 on the first joint 8a is fixedly connected to one end of the first adjusting rod 401;

[0079] The first flange 806 on the second joint 8b is fixedly connected to one end of the first adjusting rod 401 away from the lifting rod 202, and the second flange 807 on the second joint 8b is fixedly connected to one end of the second adjusting rod 402;

[0080] The first flange 806 on the third joint 8c is fixedly connected to the bottom of the end of the second adjustment rod 402 away from the first adjustment rod 401, and the second flange 807 on the third joint 8c is fixedly connected to the upper end of the L-shaped rod 501;

[0081] The first flange 806 on the fourth joint 8 d is fixedly connected to the lower end of the L-shaped rod 501 , and the second flange 807 on the fourth joint 8 d is fixedly connected to one end of the cross bar 601 .

[0082] By adopting the above technical solution, when the position of the laparoscope body 9 needs to be adjusted during the operation, the electromagnet 805 is energized at the same time, so that the first joint 8a, the second joint 8b, the third joint 8c and the fourth joint 8d are unlocked at the same time. The medical staff only needs to hold the clamping structure 7 to adjust the position and angle of the laparoscope body 9. When the adjustment is completed, it is only necessary to cut off the power to all the electromagnets 805, and the movable toothed disc 803 locks the rotating toothed disc 802 under the elastic force of the spring 804. At this time, the position and angle of the laparoscope body 9 can be adjusted and fixed, and the operation is simple and quick.

[0083] In this embodiment, in order to ensure that the laparoscope body 9 does not fall suddenly when the movable toothed disc 803 is separated from the rotating toothed disc 802, a friction plate 809 is also provided. The friction plate 809 is adjustably installed in the cylinder 801, and the friction plate 809 can rub the side of the movable toothed disc 803. In order to facilitate the adjustment of the friction force between the friction plate 809 and the rotating toothed disc 802, the inner wall of the cylinder 801 is provided with an arc groove 8012, and the friction plate 809 is slidably set in the arc groove 8012. The outer wall of the cylinder 801 is provided with a threaded hole 8013 connected to the arc groove 8012, and the inner thread of the threaded hole 8013 is rotatably connected to the fourth handle bolt 808, and the lower end of the fourth handle bolt 808 is rotatably connected to the friction plate 809. By rotating the fourth handle bolt 808 clockwise, the friction between the friction plate 809 and the rotating gear plate 802 can be increased, and by rotating the fourth handle bolt 808 counterclockwise, the friction between the friction plate 809 and the rotating gear plate 802 can be reduced. Moreover, through this setting, when the friction plate 809 is worn, the friction plate 809 can be compensated by rotating the fourth handle bolt 808.

[0084] In this embodiment, the clamping structure 7 includes a shell 701, the bottom of the shell 701 is open, the shell 701 is fixedly mounted on the end of the cross bar 601 away from the fourth joint 8d, the interior of the shell 701 is fixedly connected with a convex slide rail 708, the interior of the shell 701 is provided with an inverted trapezoidal adjustment block 702, one side of the inverted trapezoidal adjustment block 702 is provided with a concave slide groove 7021, the concave slide groove 701 is slidably sleeved on the convex slide rail 708, and the bottom of the inverted trapezoidal adjustment block 702 is fixedly connected to the convex slide rail 708. It is connected to a main clamping block 703, and the inner lower end of the shell 701 is located on both sides of the main clamping block 703 and is rotatably connected to side clamping arms 704. The upper ends of the side clamping arms 704 are in sliding contact with the inclined surfaces of the inverted trapezoidal adjustment block 702. The laparoscope body 9 is clamped in the area surrounded by the main clamping block 703 and the two side clamping arms 704. The upper end of the shell 701 is threadedly rotatably connected to a third handle bolt 705, and the lower end of the third handle bolt 705 is rotatably connected to the upper end of the inverted trapezoidal adjustment block 702.

[0085] Through the above-mentioned arrangement, when fixing the laparoscope body 9, the laparoscope body 9 is placed in the area surrounded by the main clamping block 703 and the lower ends of the two side clamping arms 704, and then the third handle bolt 705 is rotated to move the inverted trapezoidal adjustment block 702 downward, thereby moving the main clamping block 703 downward and pressing on the upper surface of the laparoscope body 9. At the same time, the inclined surface of the inverted trapezoidal adjustment block 702 squeezes the upper end of the side clamping arm 704, so that the lower end of the side clamping arm 704 moves toward the outer wall of the laparoscope body 9, thereby completing the fixation of the laparoscope body 9.

[0086] In order to calculate the holding force applied by the clamping structure 7 to the laparoscope body 9, the following key factors need to be considered in this embodiment, including the torque of the third handle bolt 705, the geometric relationship between the inverted trapezoidal adjustment block 702 and the side clamping arm 704, and the material properties. Here, the model is simplified, assuming that all contact surfaces are ideal, there is no sliding, and the materials are uniform and isotropic.

[0087] First, define some symbols:

[0088] F represents the total clamping force finally applied to the laparoscope body 9 .

[0089] T represents the torque generated when the third handle bolt 705 is rotated.

[0090] r represents the radius of the third handle bolt 705 .

[0091] α represents the inclination angle of the contact surface between the inverted trapezoidal adjustment block 702 and the side clamping arm 704 .

[0092] N represents the pressure of the main clamping block 703 on the laparoscope body 9.

[0093] S represents the pressure exerted by a single side clamping arm 704 on the laparoscope body 9 .

[0094] n represents the number of side clamping arms (2 in this example).

[0095] According to the moment balance principle, the torque T applied by the third handle bolt 705 can be converted into a force perpendicular to the axis of the third handle bolt 705, and the force is transmitted to the main clamping block 703 and the side clamping arm 704 through the inverted trapezoidal adjustment block 702. Assuming that the friction force is large enough and can be ignored, we have:

[0096] T=F bolt ×

[0097] Among them, F bolt It is the linear force generated by the third handle bolt 705.

[0098] Since the inclined surface of the inverted trapezoidal adjustment block 702 is in contact with the side clamping arm 704, according to the geometric relationship, the pressure S of the side clamping arm 704 on the laparoscope body 9 can be calculated by the following formula:

[0099] S=F bolt ×sin(α)

[0100] The main pressing block 703 directly bears the pressure from the third handle bolt 705, so:

[0101] N=F bolt ×cos(α)

[0102] The total clamping force F finally applied to the laparoscope body 9 is the sum of the pressure N of the main clamping block 703 and the pressure S of all side clamping arms 704:

[0103] F=N+n×S

[0104] F=F bolt ×cos(α)+2(F bolt ×sin(α)

[0105] F=F bolt (cos(α)+2sin(α))

[0106] because F can be further rewritten as:

[0107]

[0108] This equation gives the relationship between the clamping force F on the laparoscope body 9 and the torque T generated by the third handle bolt 705, the handle bolt radius r, and the inclination angle α of the contact surface between the inverted trapezoidal adjustment block 702 and the side clamping arm 704. The above equation can accurately calculate the clamping force applied by the clamping structure 7 to the laparoscope body 9, thereby ensuring that the clamping structure 7 can stably clamp the laparoscope body 9, thereby ensuring that the laparoscopic surgery is carried out smoothly.

[0109] In order to ensure that the upper end of the side clamping arm 704 can fit on the inclined surface of the inverted trapezoidal adjustment block 702 in a timely manner, an elastic sheet 706 is fixedly connected to the inner wall of the shell 701, and the movable end of the elastic sheet 706 contacts the upper end side of the side clamping arm 704.

[0110] In this embodiment, in order to reduce the friction between the side clamping arm 704 and the inverted trapezoidal adjustment block 702 , the upper end of the side clamping arm 704 is rotatably connected with a rolling bearing 707 , and the rolling bearing 707 is in rolling contact with the inclined surface of the inverted trapezoidal adjustment block 702 .
