Description

Technical Field

[0001] This invention relates to the field of medical devices, specifically to a gas-free abdominal wall suspension device for general surgery. Background Technology

[0002] Currently, establishing the operating space for laparoscopic surgery mainly relies on carbon dioxide pneumoperitoneum. Surgical procedures performed under pneumoperitoneum must be in a sealed state, thus requiring high sealing performance from surgical instruments and minimally invasive incisions. Furthermore, prolonged surgical time and excessively high pneumoperitoneum pressure can cause subcutaneous and mediastinal emphysema, hypercapnia, blood stasis, and air embolism. Compression from the abdominal cavity to the thoracic cavity can also cause cardiopulmonary dysfunction. This poses serious risks to infants, young children, and the elderly, especially patients with cardiovascular and pulmonary diseases, and also increases the risks associated with surgery and anesthesia. As a way to eliminate these problems with pneumoperitoneum, abdominal wall suspension using abdominal wall suspension devices is gradually being promoted.

[0003] CN201521084577.1 discloses a gasless laparoscopic abdominal wall suspension device that uses L-shaped folding plates as support plates for the suspension components to provide suspension force. During use, each L-shaped folding plate needs to be inserted into the abdominal cavity through the abdominal incision and then fixed to the main body. Repeatedly installing L-shaped folding plates through the abdominal incision can easily cause unnecessary damage to the abdominal incision site, resulting in adverse effects.

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1 to 6 In this embodiment of the invention, a gasless abdominal wall suspension device 100 for general surgery includes: a main body 10, lifting lugs 20, and an internal suspension assembly 30. The lifting lugs 20 are located on the top of the main body 10. The gasless abdominal wall suspension device 100 for general surgery can be suspended and used via the lifting lugs 20. The internal suspension assembly 30 is installed to the main body 10. The internal suspension assembly 30 includes: multiple support plates 31. The support plates 31 extend into the abdominal incision to suspend the abdominal wall from the inside. The support plates 31 enter the abdominal cavity through the abdominal incision and contact the abdominal wall to provide an upward lifting force from the inside.

[0037] In a preferred embodiment, a gasless abdominal wall suspension device 100 for general surgery further includes a pneumatic suction cup 40. The pneumatic suction cup 40 is used to adhere to the skin for external assisted suspension. The pneumatic suction cup 40 provides an upward lifting force from the outside by adhering to the abdominal skin, thus achieving assisted suspension. In a specific embodiment, the pneumatic suction cup 40 is mounted to the main body 10. The pneumatic suction cup 40 is arranged around the main body 10. The pneumatic suction cup 40 is annular and sleeved on the outer periphery of the main body 10. A support plate 31 is rotatably mounted to the main body 10. The support plate 31 has a retracted position and an extended position relative to the main body 10. The support plate 31 rotates between the retracted position and the extended position.

[0038] When in the retracted position, the support plate 31 does not extend beyond the outer surface of the main body 10 in the radial direction.

[0039] In the unfolded position, in the radial direction of the main body 10, the support plate 31 extends out of the outer surface of the main body 10 to contact the abdominal wall of the abdominal cavity to lift the abdominal wall from the inside.

[0040] When in the retracted position, the lower end of the main body 10 can be inserted into the abdominal cavity incision. Then, the support plate 31 is deployed to the deployed position within the abdominal cavity.

[0041] In one specific embodiment, the internal suspension assembly 30 further includes: a plurality of transmission gears 32, a drive gear 33, and a knob 34 for user rotation. The transmission gears 32 and the drive gear 33 are rotatably mounted to the main body 10. The support plate 31 is provided with a drive gear section 311. The number of transmission gears 32 is equal to the number of support plates 31. Each transmission gear 32 meshes with a drive gear section 311 of one support plate 31. The drive gear 33 is fixed to the knob 34 and is driven to rotate by the knob 34. The drive gear 33 meshes with multiple transmission gears 32 simultaneously. Rotation of the knob 34 drives the drive gear 33 to rotate, and the drive gear 33 drives the support plate 31 to rotate relative to the main body 10 via the transmission gears 32.

[0042] In use, first insert the lower end of the main body 10 into the abdominal cavity incision. Then, the pneumatic suction cup 40 provides an initial suspension force, creating a certain internal space within the abdominal cavity. At this point, rotating the knob 34 unfolds the support plate 31 within the abdominal cavity. Alternatively, the pneumatic suction cup 40 can be closed, allowing the internal suspension assembly 30 to provide suspension force independently. Or, the pneumatic suction cup 40 can remain open, with both the pneumatic suction cup 40 and the internal suspension assembly 30 providing suspension force from both the inside and outside.

[0043] In a preferred embodiment, the main body 10 is provided with a first limiting block 11 and a second limiting block 12. The knob 34 is provided with a protrusion 341. When the knob 34 is rotated until the protrusion 341 contacts the first limiting block 11, the support plate 31 rotates to the retracted position. When the knob 34 is rotated until the protrusion 341 contacts the second limiting block 12, the support plate 31 rotates to the extended position. Specifically, the knob 34 is located at the top of the main body 10. Lugs 20 span both sides of the knob 34. Both the first limiting block 11 and the second limiting block 12 are located at the top of the main body 10. The protrusion 341 is provided on the outer surface of the knob 34.

[0044] The rotation position of the knob 34 is limited by the first limiting block 11 and the second limiting block 12, thereby limiting the rotation position of the support plate 31. The support plate 31 can be quickly moved between the unfolded position and the retracted position by simply rotating the knob 34 until the protrusion 341 contacts the first limiting block 11 or the protrusion 341 contacts the second limiting block 12.

[0045] As a preferred embodiment, a gasless abdominal wall suspension device 100 for general surgery further includes an adjustment mechanism for adjusting the position of the pneumatic suction cup 40 relative to the main body 10.

[0046] The adjustment mechanism includes a screw 51 and an adjusting nut 52. The screw 51 is fixed to the pneumatic suction cup 40. The lower end of the screw 51 is fixed to the pneumatic suction cup 40. The upper end of the screw 51 passes through the main body 10 and forms a threaded connection with the adjusting nut 52.

[0047] The position of the pneumatic suction cup 40 can be adjusted via an adjustment mechanism to adapt to different thicknesses of the abdominal wall. During use, the surgeon can adjust the initial position of the pneumatic suction cup 40 based on experience to ensure that the support plate 31 can be deployed within the abdominal cavity. Specifically, the initial position of the pneumatic suction cup 40 can be selected based on observation of the wound surface or the degree of obesity, ensuring that the length of the main body 10 below the pneumatic suction cup 40 is greater than the thickness of the abdominal wall, i.e., the support plate 31 is located within the abdominal cavity. If the knob 34 is obstructed before reaching the final position, it indicates that the length of the main body 10 below the pneumatic suction cup 40 is insufficient. In actual use, a suitable initial position can be selected based on experience or observation, or the main body 10 can be positioned slightly longer than the expected suitable length below the pneumatic suction cup 40. If the main body 10 is slightly longer than the expected length below the pneumatic suction cup 40, and the pneumatic suction cup 40 is used for assisted suspension, the position of the pneumatic suction cup 40 can be lowered after the support plate 31 is deployed, so that the pneumatic suction cup 40 and the support plate 31 can jointly provide suspension force.

[0048] In one specific implementation, a flange 13 is formed on the top of the main body 10. A screw 51 passes through the flange 13. An adjusting nut 52 is located above the flange 13 and abuts against it. Specifically, the adjusting nut 52 is a swivel nut.

[0049] In one specific implementation, the number of screws 51 is several. The number of adjusting nuts 52 is equal to the number of screws 51. Several screws 51 are arranged around the main body 10. Specifically, the number of screws 51 is two.

[0050] In one specific embodiment, multiple transmission gears 32 are evenly distributed around the drive gear 33. The meshing between the drive gear 33 and the transmission gears 32, as well as the meshing between the transmission gears 32 and the drive gear section 311, are all external meshing. The rotation axes of the support plate 31, the drive gear 33, and the transmission gear 32 are parallel to each other.

[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0052] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
