Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically, to a suspension device for the operating cavity in laparoscopic breast surgery. Background Technology

[0002] In laparoscopic breast surgery, the operating cavity suspension device establishes the surgical cavity through the principle of physical suspension. The suspension arm can be adjusted to adjust the suspension angle according to the individual anatomical differences of different patients to create surgical cavities with different spatial shapes. At the same time, the length of the suspension chain can be adjusted according to the suspension angle and the amount of suspension force to achieve the largest volume and most suitable shape of the laparoscopic surgical cavity. This physical suspension method is not affected by air pressure and can establish a stable surgical space, providing convenience for surgical operations.

[0003] Chinese Patent CN115089240B discloses a suspension device for the operating cavity in laparoscopic breast surgery. Specifically, it includes: a support frame with leg structures and a fixed top plate at the top of the support frame, the bottom of which is fixedly connected to the top of the support frame, and a rotating device fixedly connected to the bottom of the fixed top plate; a fixed frame with a frame body and a fixed plate at the bottom of the fixed frame, the top of which is fixedly connected to the bottom of the fixed frame, and a suspension device fixedly connected to the side of the fixed plate. This invention solves the problem of the suspension device's difficulty in freely adjusting the suspension angle, allowing the suspension device to adapt to different incision angles and exhibiting high adaptability.

[0004] The inventors recognized that although the above solution solved the problem of freely adjusting the suspension angle of the suspension device, in actual use, due to the different body types of patients, obese patients have a thicker fat layer and relatively looser subcutaneous tissue, while thinner patients have a thinner fat layer and relatively tighter subcutaneous tissue. Therefore, during the operation, the traction force applied by the suspension device needs to be adjusted quickly accordingly. If the traction force is too large, it will cause excessive traction on the subcutaneous tissue, which will then cause damage. Summary of the Invention

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] (1) The present invention adjusts the moving height of the traction plate according to the thickness of the patient's skin and subcutaneous tissue, thereby controlling the traction force. Before the traction plate pulls the patient's incision, the thickness of the patient's skin and subcutaneous tissue at the incision site can be measured by the distance between the probe plate and the traction plate. The traction force of the traction plate is adjusted according to the different thicknesses of skin and subcutaneous tissue in obese and thin people, so as to avoid unnecessary damage caused by the traction plate during the traction process of the incision.

[0020] (2) The present invention uses extension plates that extend slowly to both sides according to the thickness of the patient's skin and subcutaneous tissue. After the detection plate detects the thickness of the skin and subcutaneous tissue, the second electric push rod pushes the pressure block through the push block, so that the distance of the two extension plates extending outward will be adjusted according to the thickness of the skin and subcutaneous tissue. This avoids unnecessary damage to the patient due to excessive traction force. At the same time, the extension plates extending to both sides can also improve the surgical field of the incision.

[0021] (3) The present invention can stop bleeding on the part of the incision covered by the traction plate by setting the first hemostatic gauze and the second hemostatic gauze. Since the first hemostatic gauze and the second hemostatic gauze can absorb the fresh blood flowing out of the incision in time, and the degree of blood staining on the surface of the first hemostatic gauze and the second hemostatic gauze can be used to determine whether the small blood vessels distributed in the part of the incision that is pulled are ruptured due to the pressure of the traction plate, so as to facilitate timely treatment of the rupture of the small blood vessels.

Detailed Implementation

[0032] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1 to 8 A suspension device for the operating cavity of endoscopic breast surgery includes a suspension bracket body 1 and a connecting frame 11 movably installed on the lower side of the horizontal part of the suspension bracket body 1. The lower side of the horizontal part and the right side of the vertical part of the connecting frame 11 are provided with a measuring component 2. The measuring component 2 includes a first groove 21 opened on the right side of the vertical part of the connecting frame 11.

[0034] A first slider 211 is slidably connected inside the first slide groove 21. A control console 22 is fixedly connected to the right side of the first slider 211. A controller 221 is provided on the front of the control console 22. A second slide groove 23 is provided on the right side of the control console 22. A second slider 231 is slidably connected inside the second slide groove 23. A probe plate 232 for measuring the thickness of skin and subcutaneous tissue is fixedly connected to the right side of the second slider 231. A distance sensor 26 for measuring the height of the probe plate 232 is fixedly installed on the lower side of the interior of the second slide groove 23. A first electric push rod 24 is provided between the lower side of the horizontal part of the connecting frame 11 and the upper side of the control console 22. The telescopic end of the first electric push rod 24 is fixedly connected to the upper side of the control console 22. A traction plate 25 is provided on the right side of the control console 22. The traction plate 25 is located below the probe plate 232.

[0035] By adopting the above technical solution, firstly, the suspension bracket body 1 is installed on one side of the operating table, and the connecting frame 11 is positioned above the patient's incision. Then, the controller 221 activates the first electric push rod 24 to push the control console 22 downward. During this process, the control console 22 slides within the first groove 21 on the vertical side of the connecting plate via the first slider 211. When the traction plate 25 aligns with the patient's incision, the suspension bracket body 1 adjusts the position of the traction plate 25 and inserts it into the incision. Meanwhile, the probe plate 232, located on the right side of the control console 22 via the second slider 231, is positioned on the patient's skin surface. At this time, the distance between the probe plate 232 and the traction plate 25 changes according to the thickness of the patient's skin and subcutaneous tissue. The second slider 231 slides within the second groove 23 on the side of the control console 22. The internal ranging sensor 26 calculates the distance by emitting a laser and measuring the time it takes for the light to return. The information is then transmitted to the controller 221 in front of the console 22. The controller 221 activates the first electric push rod 24 to pull the console 22 upward, causing the console 22 to pull the patient's incision through the traction plate 25. After traction, the incision will form a surgical field sufficient for the surgeon to observe, thus meeting the surgical requirements. Before pulling the patient's incision, the thickness of the skin and subcutaneous tissue at the incision site can be measured by the distance between the detection plate 232 and the traction plate 25. The traction force of the traction plate 25 can be adjusted according to the different thicknesses of skin and subcutaneous tissue in obese and thin individuals to avoid unnecessary damage caused by the traction plate 25 during the traction process.

[0036] like Figures 4 to 7 As shown, the controller 221, the ranging sensor 26 and the first electric push rod 24 are all electrically connected to an external power supply. The inner and outer sides of the traction plate 25 are provided with an extension component 27. The extension component 27 includes a first groove 271 opened on the upper left side of the traction plate 25. The right half of the traction plate 25 is arc-shaped.

[0037] A second electric push rod 272 is fixedly installed on the left side inside the first groove 271. A push plate 273 is fixedly connected to the telescopic end of the second electric push rod 272. A fixed rod 274 is fixedly connected to the right side of the push plate 273. A moving groove 275 is opened inside the pulling plate 25, and the moving groove 275 is connected to the first groove 271. A push block 276 is fixedly connected to the right end of the fixed rod 274. Pressure blocks 277 are slidably connected to both the front and rear sides inside the moving groove 275. The inclined surfaces of the two pressure blocks 277... The two pressure blocks 277 slide in contact with the inclined surfaces on the front and rear sides of the push block 276 respectively. An extension plate 278 is fixedly connected to the side of the two pressure blocks 277 that is far away from each other. The two extension plates 278 press against the front and rear sides of the traction plate 25 respectively. A second groove 279 is provided on the front and rear sides of the traction plate 25. A first tension spring 2791 is fixedly connected to the side of the second groove 279 near the fixed rod 274. The other end of the first tension spring 2791 is fixedly connected to the side of the extension plate 278 near the traction plate 25.

[0038] By adopting the above technical solution, firstly, while the first electric push rod 24 pulls the control console 22 upward, the second electric push rod 272 located inside the first groove 271 pushes the push plate 273, causing the fixed rod 274 inside the moving groove 275 to move towards the push block 276. After the push block 276 contacts the two pressure blocks 277, due to the inclined contact between the two, the push block 276 will push the two pressure blocks 277 to move forward and backward respectively. After the pressure blocks 277 move, the extension plate 278 fixed to them will also move with the pressure blocks 277, so that the extension plate 278 supports the blade edge. After the extension plate 278 is pushed, the blade edge... The first tension spring 2791 inside the second groove 279 on the side of the traction plate 25 will be pulled by the extension plate 278. After the push block 276 leaves the pressure block 277, the first tension spring 2791 will drive the extension plate 278 to return to its original position. After the probe plate 232 detects the thickness of the skin and subcutaneous tissue, the second electric push rod 272 will push the pressure block 277 through the push block 276. This causes the distance of the two extension plates 278 extending outward to be adjusted according to the thickness of the skin and subcutaneous tissue, thus avoiding unnecessary damage to the patient due to excessive traction force. At the same time, the extension plates 278 extending to both sides can also improve the surgical field of the incision.

[0039] like Figures 4 to 6 As shown, the inner and outer sides of the traction plate 25 and the extension plate 278 are provided with a hemostatic component 28, which includes a first hemostatic gauze 281 disposed on the upper side of the traction plate 25.

[0040] An embedding groove 282 is provided inside the extension plate 278, and the embedding groove 282 extends through the upper side of the extension plate 278. A second hemostatic gauze 283 is provided inside the embedding groove 282. The first hemostatic gauze 281 covers the upper side of the traction plate 25, and the upper half of the second hemostatic gauze 283 covers the upper side of the extension plate 278.

[0041] By adopting the above technical solution, during the upward movement of the traction plate 25, the first hemostatic gauze 281 set on the upper side of the traction plate 25 will contact the upper part of the incision, while the extension strip is placed in the second extension strip through the embedding groove 282.

[0042] It should be noted that after the incision is made by the scalpel, the part pulled by the traction plate will not only be compressed by the traction plate, leading to an increase in the amount and probability of bleeding, but will also be blocked by the traction plate 25, making it impossible to wipe away the flowing blood. At this time, the first hemostatic gauze 281 above the traction plate 25 will absorb the blood, and after the two extension plates 278 move to the sides, the blood flowing out of the area compressed by the extension plates 278 will be absorbed by the second hemostatic gauze 283. At this time, the bleeding point can be observed based on the first hemostatic gauze 281 and the second hemostatic gauze 283. Since the first hemostatic gauze 281 and the second hemostatic gauze 283 can absorb the blood flowing out of the incision in time, and the degree of blood staining on the surface of the first hemostatic gauze 281 and the second hemostatic gauze 283 can be used to determine whether the small blood vessels distributed in the part of the incision that is pulled have ruptured due to the compression of the traction plate 25, thus facilitating timely treatment of the ruptured small blood vessels.

[0043] like Figures 6 to 8 As shown, the inside of the traction plate 25 is provided with a blood volume detection component 3, which includes a push seat 31 that is slidably sleeved on the outside of the fixed rod 274.

[0044] A first pressure spring 32 is fixedly connected between the left side of the push seat 31 and the right side of the push plate 273. Airbags 33 are fixedly installed on both the front and rear sides of the right side inside the first groove 271. Corrugated hoses 34 are fixedly installed on the side of the two airbags 33 that are far apart. Limiting grooves 35 are opened at both the front and rear ends of the right side inside the first groove 271. After the push seat 31 moves to the right, it is inserted into the limiting groove 35. A sleeve 36 is slidably sleeved on the outside of the fixed rod 274. The left end of the sleeve 36 is fixedly connected to the right side of the push plate 273. A second pressure spring 37 is fixedly connected to the right side of the push block 276. The other end of the second pressure spring 37 is fixedly connected to the right side of the inside of the moving groove 275.

[0045] Steering components 38 are provided on the inner and outer sides of the traction plate 25 and inside the control console 22.

[0046] By adopting the above technical solution, during the process of the push plate 273 pushing the fixed rod 274, the second pressure spring 37 on the right side of the push plate 273 will push the push seat 31. At the same time, the push seat 31 will also push the sleeve 36 to slide outside the fixed rod 274. After the push seat 31 is pushed, it will compress the two airbags 33, so that the gas inside the airbags 33 is delivered to the steering assembly 38 through the corrugated hose 34, and the steering assembly 38 continuously compresses the second hemostatic gauze 283 inside the embedded groove 282. When the front and rear sides of the push seat 31 enter After the limit groove 35 is inside, the push seat 31 and sleeve 36 will stop moving, and the pressure of the push seat 31 on the airbag 33 will be maintained. Before this, the push plate 273 has driven the fixed rod 274 to contact the push block 276 and pushed the pressure block 277 to move. As the extension plate 278 moves to both sides, the relatively small second hemostatic gauze 283 will be slowly squeezed. If the blood inside the second hemostatic gauze 283 is squeezed out, it can be determined that the small blood vessels of the corresponding incision are damaged, so as to achieve the purpose of detecting the amount of bleeding at the bleeding point, and thus facilitate timely treatment.

[0047] like Figure 4 , Figures 6 to 8 As shown, the steering assembly 38 includes a guide slope 381 disposed inside the embedding groove 282 on the side away from the pull plate 25.

[0048] A collection frame 382 is inserted into the interior of the embedding groove 282, and the collection frame 382 is located on the lower side of the guide slope 381. A pressure sensor 383 is fixedly installed on the lower side of the interior of the embedding groove 282. The lower side of the collection frame 382 is in pressure contact with the upper side of the pressure sensor 383. A movable groove 384 is provided inside the embedding groove 282 on the side near the traction plate 25. The airbag 33 is connected to the movable groove 384 through the corrugated hose 34. A movable frame 385 is slidably connected inside the movable groove 384. After the movable frame 385 moves, it is in pressure contact with the second hemostatic gauze 283. A second tension spring 386 is fixedly connected between the side of the movable frame 385 near the traction plate 25 and the side of the movable frame 385 away from the traction plate 25.

[0049] A roller 387 is rotatably connected to the right side of the tension plate 25. A servo motor 388 is arranged between the right side of the control console 22 and the left side of the tension plate 25. The control console 22 is wrapped around the outside of the servo motor 388. The output end of the servo motor 388 is fixedly connected to the left side of the tension plate 25. The control console 22, the pressure sensor 383 and the servo motor 388 are all electrically connected to an external power supply.

[0050] By adopting the above technical solution, firstly, the airbag 33 delivers gas into the extension plate 278 through the corrugated hose 34. The conveying movable groove 384, which is connected to the corrugated hose 34, will first collect the gas. At the same time, the movable frame 385 will block the outlet of the movable groove 384, so that the gas is only between the movable frame 385 and the movable groove 384. Subsequently, the amount of gas inside the movable groove 384 increases, and the movable frame 385 will be pushed by the gas, causing the movable frame 385 to squeeze the lower half of the second hemostatic gauze 283. During the compression of the second gauze, if the blood absorbed by the second hemostatic gauze 283 is squeezed out, the squeezed blood will slide into the collection frame 382 through the guide slope 381. At this time, the pressure sensor 383 will transmit information to the controller 221 due to the increased weight of the collection frame 382. Subsequently, the controller 221 will start the servo motor 388 to drive the traction plate 25 to rotate. Since the roller 387 on the other side of the traction plate 25 is always in contact with the inside of the patient's incision, the roller 387 will roll inside the patient's incision after the traction plate 25 rotates.

[0051] It should be noted that the rotation angle of the traction plate 25 to both sides is between 0° and 15°. The direction of rotation of the traction plate 25 is controlled according to the pressure of the pressure sensor 383 at the corresponding position. If there is more bleeding at the extension plate 278 on one side, the first hemostatic gauze 281, which has a relatively large volume, will be used to stop the bleeding after the traction plate 25 rotates. At the same time, the rotation of the traction plate 25 will change the traction position of the incision to prevent prolonged pressure on the traction area. If there is more bleeding at the extension plates 278 on both sides, the controller 221 can control the first electric push rod 24 and the second electric push rod 272 to pull in opposite directions. At this time, the part pulled by the extension plate 278 will lose its pressure. The gauze pad 278 gradually covers the traction plate 25, and then pre-hemostasis is achieved using the first hemostatic gauze 281. After hemostasis is achieved using tools such as external hemostatic forceps, the subsequent surgical procedures can continue. If there is no significant bleeding at the traction point of the extension plate 278, the controller 221 will control the servo motor 388 to rotate the traction plate 25 every half hour. Since the rotation of the traction plate 25 is based on the amount of bleeding at the traction point of the second hemostatic gauze 283, it can not only stop the bleeding in time, but also adjust the traction position of the traction plate 25 after rotation to prevent damage to small blood vessels caused by prolonged pressure on the same area.

[0052] Working principle: First, the suspension bracket body 1 is installed on one side of the operating table. Then, the controller 221 activates the first electric push rod 24 to push the control console 22 downward. When the traction plate 25 aligns with the patient's incision, it is inserted into the incision. At this time, the distance between the detection plate 232 and the traction plate 25 changes due to the thickness of the patient's skin and subcutaneous tissue. The distance is calculated using the distance measuring sensor 26 inside the second groove 23. Subsequently, the controller 221 activates the first electric push rod 24 to pull the control console 22 upward, while the traction plate 25 pulls on the patient's incision. The second electric push rod 272, located inside the first groove 271, pushes the fixed rod 274 inside the moving groove 275 via the push plate 273. This causes the push block 276 to press the pressure block 277 forward and backward on both sides, while the extension plate 278 fixed to it supports the blade. After the push block 276 leaves the pressure block 277, the first tension spring 2791 will drive the extension plate 278 to return to its original position. At the same time, the first hemostatic gauze 281 set on the upper side of the traction plate 25 and the second hemostatic gauze 283 embedded in the groove 282 inside the extension plate 278 will both be in contact with the blade. When the upper part contacts the fixed rod 274, the second pressure spring 37 on the right side of the push plate 273 will push the push seat 31, causing the push seat 31 to compress the two airbags 33. This causes the gas inside the airbags 33 to be transported into the movable groove 384 through the corrugated hose 34. As the movable frame 385 blocks the outlet of the movable groove 384, the amount of gas inside the movable groove 384 increases. The movable frame 385 will be pushed by the gas, causing it to compress the lower half of the second hemostatic gauze 283. During the process of the movable frame 385 squeezing the second gauze, if the blood absorbed by the second hemostatic gauze 283 is squeezed out, the squeezed blood will slide into the collection frame 382 through the guide slope 381. At this time, the pressure sensor 383 will transmit information to the controller 221 due to the increased weight of the collection frame 382. Subsequently, the controller 221 will start the servo motor 388 to drive the traction plate 25 to rotate. Since the roller 387 on the other side of the traction plate 25 is always in contact with the inside of the patient's incision, the roller 387 will roll inside the patient's incision after the traction plate 25 rotates.
