[0002] With the popularization of endoscopic surgery in surgical operations and the progress of single-port laparoscopic surgery, the complexity of its surgery with general anesthesia and artificial pneumoperitoneum, as well as its related defects and even contraindications, bring certain limitations and complexities to clinical work.

[0003] In the practice of laparoscopic surgery in the past few decades, tracheal intubation general anesthesia and carbon dioxide artificial pneumoperitoneum have been indispensable. The intraoperative smoke interference affects the vision, and some patients cannot tolerate general anesthesia and pneumoperitoneum, thus resulting in limitations. Some existing clinical workers have successively adopted an extracorporeal abdominal wall suspension airless device to solve this problem. The applicant applied for a Chinese patent document with the application number 202320968500.9 on April 24, 2023, which discloses a transumbilical single-port laparoscopic airless smoke suction retractor, and on April 26, 2023, applied for a Chinese patent document with the application number 202320989050.1, which discloses a laparoscopic abdominal wall internal needle-like retractor, both of which can solve the problem of insufficient surgical space. Although the structure is simple, the installation and use are inconvenient, the all-round adjustment cannot be achieved, the use stability is poor, and it is difficult to meet the different operation requirements of medical staff during the operation, thus making the operation of airless endoscopic surgery difficult and the application range narrow.

[0004] In the existing patent, a Chinese patent document with the application number 201920451274.0 discloses an airless laparoscopic abdominal retractor, which includes a fixed bracket. A traction support frame is arranged on the fixed bracket. The traction support frame includes a vertically arranged holding handle. A rotatable rod is arranged in a through hole in the middle of the holding handle. A butterfly handle for rotating the rotatable rod is arranged at the upper end of the rotatable rod; a lower bent hook claw is arranged at the lower end of the rotatable rod, and the horizontal section of the lower bent hook claw is fixedly connected to the lower end of the rotatable rod; an upper bent hook claw is arranged above the lower bent hook claw, and the horizontal section of the upper bent hook claw is rotatably connected to the lower end of the rotatable rod; between the upper bent hook claw and the lower bent hook claw, several middle bent hook claws whose horizontal sections are rotatably connected to the lower end of the rotatable rod are also arranged. The structure of this patent document not only has a single use form but also cannot achieve all-round adjustment, and it is difficult to meet the different operation requirements of medical staff during the operation.

[0028] For the convenience of understanding by those skilled in the art, the present invention will be further described below in conjunction with embodiments and drawings. The content mentioned in the implementation manner does not limit the present invention.

[0029] As Figures 1 to 6 shown, a multifunctional laparoscope surgery non-pneumoperitoneum device provided by the present invention includes a support frame 1, a seat body 2 disposed on a cross bar 01 of the support frame 1, a height-adjusting threaded sleeve 3 rotatably connected to the seat body 2, a screw rod 4 threadedly passing through the height-adjusting threaded sleeve 3, a lifting threaded sleeve 5 threadedly sleeved outside the screw rod 4, a mounting frame 6 rotatably connected to the lifting threaded sleeve 5, a traction bracket 7 detachably mounted on the mounting frame 6, a built-in foldable cavity wall traction needle 8 detachably mounted on the traction bracket 7, an adapter 9 rotatably connected to the bottom end of the screw rod 4, a first locking member 10 for locking the adapter 9 on the screw rod 4, a support rod 11 mounted on the adapter 9, and a laparoscope non-pneumoperitoneum smoking retractor 12 detachably mounted on the support rod 11. The screw rod 4 is provided with an anti-rotation surface 13, the seat body 2 is provided with a lifting hole 14, the mounting frame 6 is provided with a through hole 15, a positioning surface 16 is provided in the lifting hole 14, the screw rod 4 slidably passes through the lifting hole 14 of the seat body 2 and the through hole 15 of the mounting frame 6, the anti-rotation surface 13 slidably abuts against the positioning surface 16, and the mounting frame 6 is locked on the screw rod 4 or the lifting threaded sleeve 5 via a locking member 17.

[0030] The utility model can be applied in thyroid surgeries and laparoscopic surgeries, etc. This embodiment takes the application in laparoscopic surgery as an example for usage description. In actual application, during laparoscopic surgery, a surgical hole is cut at the patient's navel, and the built-in foldable cavity wall retractor needle 8 in a folded state is inserted into the abdominal cavity through the surgical hole. Then, the tip of the built-in foldable cavity wall retractor needle 8 pierces through the abdominal skin from a preset position and exits the abdominal cavity. When the pulling end of the built-in foldable cavity wall retractor needle 8 abuts against the inner wall of the abdominal cavity, the pulling end of the built-in foldable cavity wall retractor needle 8 will expand in an umbrella shape to be able to abut against the inner wall of the abdominal cavity. Then, the part of the built-in foldable cavity wall retractor needle 8 located outside the abdominal cavity is installed on the traction bracket 7. Then, by rotating the lifting and lowering threaded sleeve 5, the lifting and lowering threaded sleeve 5 is threadedly connected to the screw rod 4. Since the anti-rotation surface 13 of the screw rod 4 abuts against the positioning surface 16 in the lifting hole 14, the screw rod 4 cannot rotate synchronously with the lifting and lowering threaded sleeve 5, and the lifting and lowering threaded sleeve 5 moves up and down along the screw rod 4. When the lifting and lowering threaded sleeve 5 drives the mounting bracket 6, the traction bracket 7 and the built-in foldable cavity wall retractor needle 8 to rise synchronously, the built-in foldable cavity wall retractor needle 8 will expand the abdominal cavity. Or, by rotating the height-adjusting threaded sleeve 3, the screw rod 4 drives the lifting and lowering threaded sleeve 5, the mounting bracket 6, the traction bracket 7 and the built-in foldable cavity wall retractor needle 8 to rise synchronously, so that the built-in foldable cavity wall retractor needle 8 will expand the abdominal cavity. Or, the pulling end of the endoscopic non-pneumoperitoneum smoke suction hook 12 is inserted into the abdominal cavity through the surgical hole, the connecting end of the endoscopic non-pneumoperitoneum smoke suction hook 12 is installed on the support rod 11, and by rotating the height-adjusting threaded sleeve 3, the height-adjusting threaded sleeve 3 is threadedly connected to the screw rod 4. Since the anti-rotation surface 13 of the screw rod 4 abuts against the positioning surface 16 in the lifting hole 14, the screw rod 4 cannot rotate synchronously with the height-adjusting threaded sleeve 3 and can only move up and down along the height-adjusting threaded sleeve 3. When the screw rod 4 moves up along the height-adjusting threaded sleeve 3, the rising screw rod 4 drives the adapter 9, the support rod 11 and the endoscopic non-pneumoperitoneum smoke suction hook 12 to rise synchronously, so that the endoscopic non-pneumoperitoneum smoke suction hook 12 expands the abdominal cavity, expands the surgical space, fully exposes the surgical field, facilitating the medical staff to perform laparoscopic surgery. During the process of performing laparoscopic surgery, the endoscopic non-pneumoperitoneum smoke suction hook 12 can also suck away the smoke in the abdominal cavity, enabling the medical staff to clearly perform laparoscopic surgery, effectively improving the efficiency and safety of the surgery.

[0031] It can be seen from this that the built-in collapsible cavity wall traction needle 8 and the endoscopic non-pneumoperitoneum smoke suction retractor 12 can be used to expand the abdominal cavity independently; in specific cases, in order to further expand the abdominal cavity, the built-in collapsible cavity wall traction needle 8 and the endoscopic non-pneumoperitoneum smoke suction retractor 12 can be used in combination. When the endoscopic non-pneumoperitoneum smoke suction retractor 12 is used alone, the traction bracket 7 can be disassembled; when the built-in collapsible cavity wall traction needle 8 is used alone, the endoscopic non-pneumoperitoneum smoke suction retractor 12 can be disassembled. During lifting and lowering adjustment, the lifting of the screw rod 4 can drive the built-in collapsible cavity wall traction needle 8 and the endoscopic non-pneumoperitoneum smoke suction retractor 12 to lift and lower synchronously, and the lifting of the lifting thread sleeve 5 can drive the mounting bracket 6, the traction bracket 7 and the built-in collapsible cavity wall traction needle 8 to lift and lower synchronously, so as to facilitate the adjustment of the heights of the built-in collapsible cavity wall traction needle 8 and the endoscopic non-pneumoperitoneum smoke suction retractor 12.

[0032] In different surgeries, since the required angles / positions of the endoscopic non-pneumoperitoneum smoke suction retractor 12 are different, the first locking member 10 is used to loosen the adapter 9, so that the adapter 9 can drive the support rod 11 and the endoscopic non-pneumoperitoneum smoke suction retractor 12 to rotate around the central axis of the screw rod 4 to adjust the angle / position of the endoscopic non-pneumoperitoneum smoke suction retractor 12. After the angle / position adjustment is completed, the adapter 9 can be locked on the screw rod 4 by the first locking member 10. The adjustment of the angle / position of the endoscopic non-pneumoperitoneum smoke suction retractor 12 is convenient.

[0033] In different surgeries, since the required angles / positions of the built-in collapsible cavity wall traction needle 8 are different, the locking member 17 is used to loosen the mounting bracket 6, so that the mounting bracket 6 can drive the traction bracket 7 and the built-in collapsible cavity wall traction needle 8 to rotate relative to the lifting thread sleeve 5 around the central axis of the screw rod 4 to adjust the angles / positions of the traction bracket 7 and the built-in collapsible cavity wall traction needle 8. After the angle / position adjustment is completed, the mounting bracket 6 can be locked on the screw rod 4 or the lifting thread sleeve 5 by the locking member 17. The adjustment of the angles / positions of the traction bracket 7 and the built-in collapsible cavity wall traction needle 8 is convenient.

[0034] The structure of the utility model is simple and ingeniously designed. The operation, disassembly and assembly are convenient and stable. The use forms are diverse. It can be adjusted in lifting and rotation to adjust the built-in collapsible cavity wall traction needle 8 and the endoscopic non-pneumoperitoneum smoke suction retractor 12 in all directions, meeting the different operation requirements of medical staff during the surgery, and having a wide range of uses. The utility model is particularly suitable for transumbilical laparoscopic surgery and transaxillary approach laparoscopic surgery.

[0035] In this embodiment, the seat body 2 is slidably connected to the cross bar 01 of the support frame 1, and the seat body 2 is locked to the cross bar 01 of the support frame 1 via the second locking member 18. In practical applications, when it is necessary to adjust the position of the seat body 2 on the cross bar 01 of the support frame 1, the second locking member 18 is loosened so that the seat body 2 can reciprocally slide and adjust along the cross bar 01 of the support frame 1. After the adjustment is completed, the seat body 2 is locked to the cross bar 01 of the support frame 1 by the second locking member 18 again. This structural design facilitates the adjustment of the positions of the built-in foldable cavity wall traction needle 8 and the endoscopic non-pneumoperitoneum smoking retractor 12.

[0036] In this embodiment, the seat body 2 is provided with a sliding hole 19, the cross bar 01 of the support frame 1 penetrates through the sliding hole 19, and a positioning and adjusting structure is provided between the inner wall of the sliding hole 19 and the cross bar 01 of the support frame 1. During or after adjustment, the positioning and adjusting structure positions the seat body 2 on the cross bar 01 of the support frame 1, improving the position accuracy and stability of adjusting the seat body 2.

[0037] In this embodiment, the positioning and adjusting structure includes a positioning block 20 provided on the top wall of the sliding hole 19 and a plurality of positioning grooves 21 arranged at equal intervals along the length direction of the cross bar 01 of the support frame 1. The positioning block 20 is in concave-convex fit with any one of the positioning grooves 21, and a lifting gap 22 is provided between the bottom wall of the sliding hole 19 and the bottom surface of the cross bar 01 of the support frame 1. The size of the lifting gap 22 is not less than the groove depth of the positioning groove 21. Specifically, the number of the positioning blocks 20 is two, and the two positioning blocks 20 are arranged at a distance and in parallel.

[0038] In practical applications, when it is necessary to adjust the position of the seat body 2, the second locking member 18 is loosened, the seat body 2 is lifted so that the positioning block 20 moves away from the positioning groove 21. At this time, the seat body 2 can be driven to move along the cross bar 01 of the support frame 1. When the seat body 2 moves to the required position, the positioning block 20 aligns with the positioning groove 21 at the corresponding position, and the lifting force on the seat body 2 is released, so that the seat body 2 hangs on the cross bar 01 of the support frame 1 under the action of gravity. The positioning block 20 and the positioning groove 21 are in positioning cooperation to position the seat body 2 at the required position on the cross bar 01 of the support frame 1. Finally, the seat body 2 is locked to the cross bar 01 of the support frame 1 by the second locking member 18.

[0039] In another embodiment, the positioning and adjusting structure includes a positioning groove 21 provided on the top wall of the sliding hole 19 and a plurality of positioning blocks 20 arranged at equal intervals along the length direction of the cross bar 01 of the support frame 1. The positioning groove 21 is in concave-convex fit with any one of the positioning blocks 20, and a lifting gap 22 is provided between the bottom wall of the sliding hole 19 and the bottom surface of the cross bar 01 of the support frame 1. The size of the lifting gap 22 is not less than the groove depth of the positioning groove 21. The working principle of the positioning and adjusting structure with this structural design is the same as that of the above-mentioned positioning and adjusting structure, and will not be elaborated here.

[0040] In this embodiment, a first T-shaped groove 23 communicating with the lifting hole 14 is provided on the top surface or the bottom surface of the seat body 2. A first ring 24 is provided on the peripheral wall of one end of the height-adjusting threaded sleeve 3. The first ring 24 is rotatably clamped in the first T-shaped groove 23, and the other end of the height-adjusting threaded sleeve 3 protrudes out of the first T-shaped groove 23. This structural design not only facilitates the disassembly, assembly and maintenance of the seat body 2 and the height-adjusting threaded sleeve 3, but also enables the height-adjusting threaded sleeve 3 to rotate relative to the seat body 2.

[0041] Specifically, a second T-shaped groove communicating with the through hole 15 is provided on the top surface or the bottom surface of the mounting bracket 6. A second ring is provided on the peripheral wall of one end of the lifting threaded sleeve 5. The second ring is rotatably clamped in the second T-shaped groove, and the other end of the lifting threaded sleeve 5 protrudes into the second T-shaped groove. This structural design not only facilitates the disassembly, assembly and maintenance of the mounting bracket 6 and the lifting threaded sleeve 5, but also enables the lifting threaded sleeve 5 to rotate relative to the mounting bracket 6.

[0042] Specifically, a first screwing portion is provided at the end of the height-adjusting threaded sleeve 3 away from the first ring 24, and a second screwing portion is provided at the end of the lifting threaded sleeve 5 away from the second ring. By providing the first screwing portion and the second screwing portion, it is convenient for the user to rotate the height-adjusting threaded sleeve 3 and the lifting threaded sleeve 5.

[0043] In this embodiment, an insertion groove 25 is recessed on the top surface of the mounting bracket 6. The traction bracket 7 is inserted into the insertion groove 25, and the traction bracket 7 is locked to the mounting bracket 6 via a third locking member 26. This structural design not only facilitates the disassembly, assembly and maintenance of the mounting bracket 6 and the traction bracket 7, but also facilitates the adjustment of the relative position between the mounting bracket 6 and the traction bracket 7 and the swinging direction of the traction bracket 7, making the use more convenient.

[0044] In this embodiment, the built-in foldable cavity wall traction needle 8 includes a needle rod 27, a mounting seat 28 connected to one end of the needle rod 27, and a plurality of folding plates 29 respectively rotatably connected to the mounting seat 28. A skin-breaking sharp corner 30 is provided at the other end of the needle rod 27. The ends of the plurality of folding plates 29 away from the mounting seat 28 are provided with a contact unfolding arc surface 31 and can approach or move away from the axis of the needle rod 27. The plurality of folding plates 29 are unfolded to form a cavity wall support structure, and the needle rod 27 is detachably connected to the traction bracket 7.

[0045] In practical applications, an abdominal incision is made to form a surgical hole, which can be opened on the navel. A plurality of folding plates 29 are close to each other to be in a folded state. The piercing sharp corner 30 of the needle rod 27 first enters the abdominal cavity through the surgical hole. When the needle rod 27 moves to a preset position, the piercing sharp corner 30 pierces the abdominal skin and penetrates out of the abdominal cavity. Then, after the contact unfolding arc surface 31 of the plurality of folding plates 29 receives a force, it rotates relative to the mounting seat 28, so that the plurality of folding plates 29 move away from each other and open in an umbrella shape until the plurality of folding plates 29 are in an unfolded state to form a cavity wall support structure. The cavity wall support structure (the plurality of unfolded folding plates 29) abuts against the inner wall of the abdominal cavity. Then, the needle rod 27 is locked on the traction bracket 7, and the traction bracket 7 is lifted, so that the traction bracket 7 applies a pulling force to the built-in foldable cavity wall traction needle 8. This pulling force acts on the inner wall of the abdominal cavity through the cavity wall support structure, so that the cavity wall support structure pulls the abdominal skin, thereby expanding the abdominal cavity.

[0046] In this embodiment, a plurality of locking holes 32 are provided on the traction bracket 7. The needle rod 27 can penetrate through the locking holes 32, and the needle rod 27 is locked in the corresponding locking holes 32 via a fourth locking member 33.

[0047] Specifically, the traction bracket 7 is in a ring shape, an arc shape, an L shape, a semi-closed ring shape, etc.

[0048] In this embodiment, the support rod 11 is slidably connected to the adapter 9, and the support rod 11 is locked on the adapter 9 via a fifth locking member 34. This structural design facilitates the adjustment of the relative position between the support rod 11 and the adapter 9, thereby adjusting the position of the endoscopic non-pneumoperitoneum smoking retractor 12, and the adjustment is convenient.

[0049] In this embodiment, the endoscopic non-pneumoperitoneum smoking retractor 12 is an L-shaped thyroid surgery retractor or an L-shaped laparoscopic surgery retractor. When a thyroid surgery needs to be performed, a thyroid surgery retractor is used; when a laparoscopic surgery needs to be performed, a laparoscopic surgery retractor is used.
