Description

Technical Field

[0001] The utility model belongs to the technical field of laparoscopic brackets, and particularly relates to a bracket for laparoscopic surgery. Background Art

[0002] As one of the main forms of minimally invasive surgery, laparoscopic surgery has been widely used in the surgical field due to its advantages such as small trauma, fast recovery, and few complications. During laparoscopic surgery, it is necessary to support surgical instruments, especially laparoscopes, to ensure a clear surgical field and the smooth progress of the operation. Traditional laparoscopic surgeries usually rely on manual support by doctors or assistants to stabilize the laparoscope, but this method has many deficiencies. First, manual support is easily affected by factors such as operator fatigue and hand tremors, resulting in the shaking of the laparoscope and affecting the stability of the surgical field. Second, manual support requires additional human resources, increasing the workload of the surgical team. Finally, in complex surgical operations, manual support may not be able to meet the need for quickly adjusting the position and angle of the laparoscope, thus limiting the flexibility and efficiency of the operation. Content of the Utility Model

[0003] The purpose of the utility model is to provide a bracket for laparoscopic surgery, which can stably support the laparoscope, flexibly adjust its different angles, and improve the surgical efficiency.

[0004] The bracket for laparoscopic surgery includes a sleeve with an upward opening. A fixed rod is inserted into the sleeve. A first threaded hole is opened on the side wall of the sleeve, and a first screw threadedly engaged with it is inserted into the first threaded hole. The tightening end of the first screw abuts against the side wall of the fixed rod. A fixing component for fixing the sleeve to the operating table is arranged at the bottom of the sleeve. A hinge seat is fixed at the top of the fixed rod. A support arm is arranged at the hinge seat. One end of the support arm is fixed with a hinge rod, and the hinge rod is hinged to the hinge seat through a damping rotating shaft. The other end of the support arm is fixed with a universal shaft seat in a ring structure. A universal ball is arranged in the universal shaft seat. A number of through slots are opened on the universal shaft seat. A locking nut is threadedly connected to the universal shaft seat. A connecting rod is arranged on the universal ball, and a clamping component for clamping the laparoscope is arranged at the movable end of the connecting rod.

[0005] Further, the clamping component includes a limiting frame in a "C" - shaped structure fixed on the connecting rod. Symmetric second threaded holes are opened on both side walls of the limiting frame. Second screws are threadedly connected to both second threaded holes. A clamping plate rotatably connected to the second screws is arranged inside the limiting frame.

[0006] Further, the two clamping plates are arc - shaped plates in symmetric distribution, and the centers of the arcs of the two clamping plates are located between the two clamping plates.

[0007] Further, an anti - slip pad is arranged on the inner side wall of the clamping plate.

[0008] Furthermore, the side wall of the fixing rod is provided with two symmetrically distributed sliding grooves, each of which is provided with a slider that is slidably matched with the sliding groove and fixed to the inner wall of the sleeve.

[0009] Furthermore, the threaded connection between the universal joint seat and the locking nut is a tapered thread connection.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The utility model fixes the sleeve on the operating table by a fixing component and clamps and fixes it by a clamping component. Under the action of the hinge seat and the damping shaft, the hinge rod drives the support arm to rotate around the hinge point, so that the position of the laparoscope on the support arm changes, avoiding it affecting the field of view of medical staff. When the angle of the laparoscope needs to be adjusted, the locking nut is loosened to loosen the restraint on the universal shaft seat, the spacing between the several through grooves on the locking nut becomes larger, and the universal ball rotates freely in the universal shaft seat, thereby driving the angle of the laparoscope fixed at the movable end of the connecting rod to change. The locking nut is tightened to fix the position of the universal ball, which can stably support the laparoscope and flexibly adjust its different angles, thereby improving the efficiency of the operation.

A fixing component for fixing it to the operating table is provided at the bottom of the sleeve 4. A hinge seat 7 is fixed at the top of the fixing rod 5. A support arm 10 is provided at the hinge seat 7. One end of the support arm 10 is fixed with a hinge rod 9. The hinge rod 9 is hinged to the hinge seat 7 through a damping rotating shaft 8. The other end of the support arm 10 is fixed with a universal shaft seat 11 in a ring structure. A universal ball 13 is arranged inside the universal shaft seat 11. A plurality of through slots are provided on the universal shaft seat 11. A locking nut 12 is threadedly connected to the universal shaft seat 11. A connecting rod 17 is arranged on the universal ball 13. A clamping component for clamping the laparoscope is arranged at the movable end of the connecting rod 17; The fixing rod 5 extends into the interior of the sleeve 4 from the opening at the top of the sleeve 4. A first threaded hole is provided on the side wall of the upper section of the sleeve 4. A first screw 18 is threadedly connected to the first threaded hole. Tighten the first screw 18 so that its tightening end abuts against the side wall of the fixing rod 5, thereby fixing the position of the fixing rod 5. Loosen the first screw 18 to release its restraint on the fixing rod 5. Move the position of the fixing rod 5 inside the sleeve 4. Adjust the height of the fixing rod 5 according to the requirements of laparoscopic surgery. Then tighten the first screw 18 to fix it. A fixing component is provided at the bottom of the sleeve 4. The fixing component includes a fixing frame 1 in a "C" - shaped structure welded or adhered to the bottom of the sleeve 4. A threaded hole is provided on the side wall below the fixing frame 1. A screw rod 2 is threadedly connected to the threaded hole. A fixing plate 3 rotatably connected to the screw rod 2 is arranged inside the fixing frame 1. A knob is fixed at the end of the screw rod 2 outside the fixing frame 1. The screw rod 2 and the fixing plate 3 are rotatably connected through a bearing. During use, place the fixing frame 1 on the edge of the operating table. Rotate the knob to drive the screw rod 2 to move in the threaded hole. The movement of the screw rod 2 drives the fixing plate 3 to move, so that the fixing plate 3 fits with the operating table, thereby fixing the fixing frame 1 on the operating table. According to the surgical needs of medical staff, fix the sleeve 4 at a position that does not obstruct the vision and operation of medical staff through the fixing component, ensuring the stability of the sleeve 4 and providing a basis for the support and fixation of the laparoscope;

[0019] The top of the fixed rod 5 is welded or glued with an articulated seat 7, and an articulated rod 9 is hingedly connected to the articulated seat 7 through a damping shaft 8. The movable end of the articulated rod 9 is welded or glued with a support arm 10, and the articulated rod 9 and the support arm 10 are driven to rotate around the hinge point of the articulated seat 7 through the articulated seat 7 and the damping shaft 8. The damping shaft 8 provides appropriate damping force through its built-in damping device, so that the articulated rod 9 can move smoothly during the rotation process. The damping shaft 8 can maintain the stability of the articulated rod 9 in the required position, and can ensure that the support arm 10 will not shake or tilt at will without external support, so that the support arm 10 is more stable during the rotation process, and the support for the laparoscope is more stable; the other end of the support arm 10 is welded or glued with a universal shaft seat 11, and a number of evenly distributed through grooves are provided at the opening of the universal shaft seat 11. A universal ball 13 is embedded in the universal shaft seat 11, and a connecting rod 17 is welded or glued on the universal ball 13. The other end of the connecting rod 17 The universal ball 13 can be freely rotated in the universal shaft seat 11, thereby adjusting the angle of the laparoscope according to the surgical requirements, making its use more flexible and avoiding affecting the field of view;

[0020] The connecting rod 17 is provided with a clamping assembly, which includes a hoop fixed to the movable end of the connecting rod 17. The hoop is composed of a hoop plate, a wing plate, a tie plate, a bolt and an inner liner. It is formed by hingedly joining the left and right half hoop plates. The left and right half hoop plates are both semicircular, with both ends of the semicircular bent outward to form a mounting ear. The mounting ears are provided with threaded holes, and a bolt is passed through the threaded hole. The laparoscope is placed between the two hoop plates of the hoop, the two hoop plates are closed, so that the inner side walls of the two hoop plates are in close contact with the laparoscope, and then the bolt is tightened to fix the position of the two hoop plates, thereby fixing the laparoscope on the connecting rod 17, so that it maintains its stability during the operation, does not need to be held by medical staff, saves human resources, and further reduces the workload of medical staff.

[0021] like Figure 1 、 Figure 2 and Figure 3As shown, the side wall of the fixing rod 5 is provided with two symmetrically distributed sliding grooves, each of which is provided with a slider 6 that is slidably matched with the slider and fixed to the inner wall of the sleeve 4. The slider 6 is adhered to the inner wall of the sleeve 4. Through the sliding fit between the slider 6 and the sliding groove, the fixing rod 5 moves more smoothly in the sleeve 4, ensuring the stability of the laparoscope and preventing the fixing rod 5 from detaching from the sleeve 4, thereby ensuring the integrity of the connection between the sleeve 4 and the fixing rod 5;

[0022] like Figure 1 、 Figure 2 and Figure 3 As shown, the threaded connection between the universal joint seat 11 and the locking nut 12 is a tapered thread connection, and the external thread on the outer wall of the universal joint seat 11 and the internal thread on the inner wall of the locking nut 12 are tapered thread connections, making the connection between the two tighter and better tightening the universal ball 13 to prevent it from rotating and causing the laparoscope to shake.

[0023] During actual use, the sleeve 4 is fixed to the appropriate position of the operating bed by the fixing assembly to avoid obstruction of the medical staff's field of vision, and then the laparoscope is fixed to the support arm 10 by the clamping assembly. By tightening the first screw 18, the tightening end is pressed against the side wall of the fixing rod 5. The height of the fixing rod 5 is adjusted as needed to make the support arm 10 located at different heights. With the cooperation of the hinge seat 7 and the damping shaft 8, the hinge rod 9 drives the support arm 10 to rotate around its hinge point, adjusts the swing angle of the support arm 10, and then loosens the locking nut 12 to loosen the constraint on the universal shaft seat 11. The universal ball 13 rotates freely in the universal shaft seat 11, thereby causing the angle of the laparoscope clamped by the movable end of the connecting rod 17 to change, and the angle of the laparoscope is flexibly adjusted. Medical staff can better use the laparoscope for surgery, improve surgical efficiency, and further reduce the workload of medical staff.

[0024] Example 2

[0025] This embodiment further illustrates the technology. Figure 1 、 Figure 2 and Figure 3As shown, the clamping assembly includes a limiting frame 15 with a "C" - shaped structure fixed on the connecting rod 17. Symmetric second threaded holes are provided on both side walls of the limiting frame 15. Second screws 16 are threadedly connected to both second threaded holes. A clamping plate 14 rotatably connected to the second screws 16 is arranged inside the limiting frame 15; the movable end of the connecting rod 17 is welded or adhered with the limiting frame 15. Second threaded holes are provided on both side walls of the limiting frame 15. Second screws 16 are threadedly connected to the two second threaded holes. The movable ends of the second screws 16 are rotatably connected to the clamping plate 14 through bearings. Place the laparoscope between the two clamping plates 14, rotate the second screws 16 to make them drive the clamping plate 14 to move towards the middle of the limiting frame 15. The two clamping plates 14 press against the laparoscope to clamp and fix it, ensuring its stability during the operation, avoiding its shaking, and further liberating medical staff and reducing their work burden;

[0026] As Figure 1 , Figure 2 and Figure 3 shown, the two clamping plates 14 are arc - shaped plates with symmetric distribution. The centers of the arcs of the two clamping plates 14 are located between the two clamping plates 14. The side wall of the laparoscope is arc - shaped. The arcs of the two clamping plates 14 have the same radian as the side - wall radian of the laparoscope, enabling their inner walls to better contact the side wall of the laparoscope and better clamping and fixing the laparoscope to ensure its stability; and an anti - slip pad is provided on the inner wall of the clamping plate 14. The anti - slip pad is adhered to the inner wall of the clamping plate 14. The anti - slip protrusions of the anti - slip pad can increase the friction between it and the laparoscope, better clamping and fixing it. Moreover, the anti - slip pad is made of rubber material, which is soft and elastic, protecting the laparoscope while clamping and fixing it to avoid scratching the laparoscope.
