DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 8 , an operating cavity suspension device for breast laparoscopic surgery, comprising a suspension bracket body 1 and a connecting frame 11 movably mounted on the lower side of the horizontal portion of the suspension bracket body 1, a measuring component 2 is provided on the lower side of the horizontal portion of the connecting frame 11 and the right side of the vertical portion, and the measuring component 2 comprises a first slide groove 21 provided on the right side of the vertical portion of the connecting frame 11;

[0034] The first slide groove 21 is internally slidably connected with a first slider 211, the right side of the first slider 211 is fixedly connected with a console 22, a controller 221 is arranged on the front of the console 22, a second slide groove 23 is provided on the right side of the console 22, a second slider 231 is internally slidably connected with the second slide groove 23, a detection 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 measuring sensor 26 for measuring the height of the detection plate 232 is fixedly installed on the lower side of the inner part 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 console 22, and the telescopic end of the first electric push rod 24 is fixedly connected to the upper side of the console 22, a pulling plate 25 is provided on the right side of the console 22, and the pulling plate 25 is located below the detection plate 232.

[0035] By adopting the above technical solution, the suspension bracket body 1 is first installed to one side of the operating table, and the connecting frame 11 is located above the patient's incision. Then, the first electric push rod 24 is started by the controller 221 to push the console 22 downward. During this process, the console 22 will slide in the first slide groove 21 on the side of the vertical part of the connecting plate through the first slider 211. When the traction plate 25 corresponds to the position of the patient's incision, the position of the traction plate 25 is adjusted by the suspension bracket body 1 and inserted into the incision. The detection plate 232 set on the right side of the console 22 by the second slider 231 will be on the patient's skin surface. At this time, the distance between the detection plate 232 and the traction plate 25 will change according to the thickness of the patient's skin and subcutaneous tissue, and the second slider 231 slides in the second slide groove 23 on the side of the console 22, and then the second slide groove 23 The internal distance measuring sensor 26 calculates the distance by emitting a laser and measuring the time it takes to be reflected back, and then transmits the information to the controller 221 in front of the console 22, and the first electric push rod 24 is activated by the controller 221 to pull the console 22 upward, so that the console 22 pulls the patient's incision through the traction plate 25. After the traction, the incision will form a surgical field that is sufficient for the surgeon to observe, so as to meet the surgical needs. Before the traction plate 25 pulls the patient's incision, the thickness of the skin and subcutaneous tissue at the patient's incision can be measured by the distance between the detection plate 232 and the traction plate 25, and the traction force of the traction plate 25 is adjusted accordingly according to the different thicknesses of the skin and subcutaneous tissue of obese people and thin people, so as to avoid unnecessary damage caused by the traction plate 25 in the process of pulling the incision.

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

[0037] A second electric push rod 272 is fixedly installed on the left side of 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, 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, and a pressure block 277 is slidably connected to the front and rear sides of the moving groove 275, and the inclined surfaces of the two pressure blocks 277 are The two pressure blocks 277 are respectively in sliding contact with the inclined surfaces on the front and rear sides of the pushing block 276, and the sides away from each other are fixedly connected with extension plates 278. The two extension plates 278 are respectively pressed and contacted with the front and rear sides of the pulling plate 25. The front and rear sides of the pulling plate 25 are provided with second grooves 279. The inside of the second groove 279 is fixedly connected with a first tension spring 2791 on one side close to the fixed rod 274, and the other end of the first tension spring 2791 is fixedly connected to the side of the extension plate 278 close to the pulling plate 25.

[0038] By adopting the above technical solution, first, while the first electric push rod 24 pulls the console 22 upward, the second electric push rod 272 in the first groove 271 will push the push plate 273, so that the fixed rod 274 in the movable groove 275 moves toward the push block 276. After the push block 276 contacts the two pressure blocks 277, due to the contact of the inclined surfaces of 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 thereto will also move with the pressure blocks 277, so that the extension plate 278 supports the knife edge. After the extension plate 278 is pushed, the knife edge The first tension spring 2791 inside the second groove 279 on the side of the pulling plate 25 will be pulled by the extension plate 278, and after the pushing block 276 leaves the pressure block 277, the first tension spring 2791 will drive the extension plate 278 to reset. After the detection 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 pushing block 276, causing the outward extension distance of the two extension plates 278 to be adjusted accordingly according to the thickness of the skin and subcutaneous tissue, thereby avoiding unnecessary damage to the patient due to excessive pulling force. At the same time, the extension plates 278 extending to both sides can also improve the surgical field of view of the incision.

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

[0040] An embedding groove 282 is opened inside the extension plate 278, and the embedding groove 282 passes through the upper side of the extension plate 278. A second hemostatic gauze 283 is arranged inside the embedding groove 282. The first hemostatic gauze 281 covers the upper side of the pulling 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, firstly, during the upward movement of the pulling plate 25, the first hemostatic gauze 281 disposed on the upper side of the pulling plate 25 will contact the upper part of the inner part of the incision, and the extension strip will place the second extension strip through the embedding groove 282;

[0042] It should be noted that after the incision is cut by the scalpel, the part pulled by the traction plate will not only be compressed by the traction plate, resulting in increased bleeding volume and probability of bleeding, but will also be blocked by the traction plate 25, making it impossible to wipe off the flowing blood. At this time, the first hemostatic gauze 281 above the traction plate 25 will absorb the first hemostatic gauze 281, and after the two extension plates 278 move to both sides, the blood flowing out of the part compressed by the extension plate 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, 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 where the incision is pulled are ruptured due to the compression of the traction plate 25, thereby facilitating timely treatment of the ruptured small blood vessels.

[0043] like Figures 6 to 8 As shown, a blood volume detection component 3 is provided inside the pulling plate 25 , and the blood volume detection component 3 includes a pushing seat 31 slidably sleeved on the outer side of the fixing rod 274 .

[0044] A first pressure spring 32 is fixedly connected between the left side of the pushing seat 31 and the right side of the pushing plate 273, airbags 33 are fixedly installed on the front and rear sides of the right side of the first groove 271, and a corrugated hose 34 is fixedly installed on the side away from the two airbags 33. Limiting grooves 35 are provided on the front and rear ends of the right side of the first groove 271. The pushing seat 31 is inserted into the limiting groove 35 after moving to the right. A sleeve 36 is provided on the outer sliding sleeve of the fixed rod 274, and the left end of the sleeve 36 is fixedly connected to the right side of the pushing plate 273. A second pressure spring 37 is fixedly connected to the right side of the pushing block 276, and the other end of the second pressure spring 37 is fixedly connected to the right side of the movable groove 275.

[0045] A steering assembly 38 is provided on the inner and outer sides of the pulling plate 25 and the interior of the console 22 .

[0046] By adopting the above technical solution, first, when the pushing plate 273 pushes the fixing rod 274, the second pressure spring 37 on the right side of the pushing plate 273 will push the pushing seat 31, and at the same time, the pushing seat 31 will also push the sleeve 36 to slide on the outside of the fixing rod 274. After the pushing seat 31 is pushed, it will squeeze the two air bags 33, so that the internal gas of the air bags 33 is transported to the inside of the steering assembly 38 through the corrugated hose 34, and the second hemostatic gauze 283 embedded in the groove 282 is continuously squeezed through the steering assembly 38. When the front and rear sides of the pushing seat 31 enter After being inside the limiting groove 35, the pushing seat 31 and the sleeve 36 will stop moving, and the squeezing degree of the airbag 33 by the pushing seat 31 will be maintained. Before this, the pushing plate 273 has driven the fixing rod 274 to contact the pushing block 276, and pushed the pressure block 277 to move. During the process of the extension plate 278 moving to both sides, the relatively smaller 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 at the corresponding position of the incision are damaged, so as to achieve the purpose of detecting the amount of bleeding at the bleeding point, and then facilitate timely treatment.

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

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

[0049] The right side of the pulling plate 25 is rotatably connected to a roller 387, a servo motor 388 is provided between the right side of the console 22 and the left side of the pulling plate 25, the 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 pulling plate 25, and the 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, the airbag 33 first delivers the gas into the extension plate 278 through the corrugated hose 34, and the delivery movable groove 384 connected to the corrugated hose 34 will first collect the gas, and 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, and then the amount of gas in the movable groove 384 increases, and the movable frame 385 will be pushed by the gas, so that the movable frame 385 squeezes the lower half of the second hemostatic gauze 283, and the movable frame 385 During the squeezing 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 increases due to the weight of the collection frame 382, ​​and the pressure sensor 383 will transmit information to the controller 221. Then, the servo motor 388 is started by the controller 221 to drive the pulling plate 25 to rotate. Since the roller 387 on the other side of the pulling plate 25 is always in contact with the inside of the patient's incision, after the pulling plate 25 rotates, the roller 387 will roll inside the patient's incision.

[0051] It should be noted that the rotation angles of the pulling plate 25 to both sides are between 0° and 15°, and the rotation direction of the pulling plate 25 will be controlled according to the pressure applied to the pressure sensor 383 at the corresponding position. If the amount of bleeding at the unilateral extension plate 278 is large, the bleeding will be stopped by the first hemostatic gauze 281 which is relatively large in volume after the pulling plate 25 is rotated. At the same time, after the pulling plate 25 is rotated, the pulling position of the incision will be changed to prevent long-term compression of the pulling position. If the amount of bleeding at the extension plates 278 on both sides is large, the controller 221 can be used to control the first electric push rod 24 and the second electric push rod 272 to be pulled in opposite directions. At this time, the part pulled by the extension plate 278 will lose its The traction plate 25 is supported and gradually covered on top of the traction plate 25, and then pre-hemostasis is performed by the first hemostatic gauze 281, and then the subsequent surgical operation is continued after hemostasis is performed by external hemostatic forceps and other tools. If there is no heavy bleeding at the traction point of the extension plate 278, the controller 221 will control the servo motor 388 to drive the traction plate 25 to rotate every half an 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, not only can the bleeding point be stopped in time, but the traction plate 25 can also change the traction position of the incision after rotation to prevent small blood vessels from being damaged after the traction plate 25 compresses the same point for a long time.

[0052] Working principle: First, install the suspension bracket body 1 to one side of the operating table, then start the first electric push rod 24 through the controller 221 to push the console 22 downward, and when the pulling plate 25 corresponds to the position of the patient's incision, it is inserted into the incision. At this time, the distance between the detection plate 232 and the pulling plate 25 will change according to the thickness of the patient's skin and subcutaneous tissue, and the distance is calculated with the help of the distance measuring sensor 26 inside the second slide 23. Then, the controller 221 starts the first electric push rod 24 to pull the console 22 upward, and the pulling plate 25 pulls the patient's incision, and at the same time When the second electric push rod 272 in the first groove 271 pushes the fixed rod 274 in the movable groove 275 through the pushing plate 273, the pushing block 276 squeezes the pressure block 277 to the front and rear sides respectively, and the extension plate 278 fixed thereto supports the knife edge. After the pushing block 276 leaves the pressure block 277, the first tension spring 2791 will drive the extension plate 278 to reset. At the same time, the first hemostatic gauze 281 arranged on the upper side of the pulling plate 25 and the second hemostatic gauze 283 in the embedded groove 282 in the extension plate 278 will contact the knife edge. When the push plate 273 pushes the fixing rod 274, the second pressure spring 37 on the right side of the push plate 273 will push the push seat 31, so that the push seat 31 squeezes the two air bags 33, so that the internal gas of the air bags 33 is transported to the movable groove 384 through the corrugated hose 34. The movable frame 385 will block the outlet of the movable groove 384, and then the amount of gas in the movable groove 384 will increase. The movable frame 385 will be pushed by the gas, so that the movable frame 385 squeezes the lower half of the second hemostatic gauze 283. During the process of squeezing the second gauze by the movable frame 385, 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 increase due to the weight of the collection frame 382, ​​and the pressure sensor 383 will transmit information to the controller 221. Then, the servo motor 388 will be started through the controller 221 to drive the pulling plate 25 to rotate. Because the roller 387 on the other side of the pulling plate 25 is always in contact with the inside of the patient's incision, after the pulling plate 25 rotates, the roller 387 will roll inside the patient's incision.
