Description

Technical Field

[0001] The present invention relates to, specifically, an incision protection device with a smoking function. Background Art

[0002] During neck surgeries, energy instruments such as electrosurgical knives and ultrasonic knives are commonly used. The high temperature generated during operation easily scald the edges of the surgical incision, and the use of a retractor during the operation easily damages the elastic fibers around the incision, aggravating postoperative scar hyperplasia. Nowadays, most methods for protecting the incision during neck surgeries are to cover it with dressing papers. However, during the operation, the dressing is prone to falling off and still damages the skin at the incision site. Existing incision protection sleeves are mostly applicable to abdominal surgical incisions. Abdominal incisions are located in hidden areas, and patients have low requirements for skin aesthetics. Moreover, abdominal surgical incisions are usually type II or type III incisions. Therefore, preventing incision infection is the primary issue. However, neck surgical incisions are type I incisions, and aseptic operation is the primary measure. Neck surgical incisions are small and not suitable for existing incision protection sleeves. And if a fixed size is adopted, during specific operations, only a relatively close size can often be found, and it is impossible to achieve a good fit with the wound. Even if the protection sleeve is too large, the incision may be stretched open for a long time during the operation, resulting in ischemia and whitening of the incision.

[0003] For example, a thyroid surgery incision protection component with the patent number (CN202110427791.6) includes a housing. The housing includes a transportation cavity and a storage cavity. A protection strip is arranged inside the housing. The protection strip is made of TPE material, and the cross-section of the protection strip is arc-shaped and is arranged in a rolled state in the storage cavity. One end penetrates through the transportation cavity and extends outside the housing. A transportation mechanism is arranged in the transportation cavity. The transportation mechanism includes a driving pulley group and an auxiliary pulley group. A cutting mechanism is arranged at the opening of the transportation cavity. The cutting mechanism includes a pressing part and a cutting part.

[0004] The above structure can achieve the protection of neck incisions, and can be flexibly adapted to the size of the wound, effectively preventing surgical incision infection and facilitating the operation of medical staff. However, the smoke generated during the operation of the electrosurgical knife and ultrasonic knife contains many harmful substances such as tumor cells and oil fumes, which easily pollute the environment and also cause harm to medical staff and patients. The above structure lacks the function of absorbing the harmful smoke generated during the operation. Summary of the Invention

Detailed implementation manners

[0032] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

When in use, first operate the connection component 3 to fix the protection component 2 and the suction component 4 together. Through the setting of the connection component 3, connection is carried out through threads, which is convenient for the disassembly and fixation of the whole device, and at the same time ensures good fixation effect and sealing efficiency, preventing the situation that the fixation is not firm and affects the use, and at the same time preventing the occurrence of smoke overflow due to poor sealing. While carrying out the connection and fixation, the suction force is amplified, reducing the power consumption of the motor 41 output. Then operate the concave tube 1, fix one end of the concave tube 1 on the protection component 2, and the other end passes through the protection component 2 to form a ring. Close the protection component 2 to the incision, operate the protection component 2 to make the concave tube 1 automatically expand, adapt to the incision, clamp and wrap the incision to play a protective role, realizing pure mechanical structure transmission, realizing the automatic expansion function of the concave tube 1, enabling the concave tube 1 to automatically adapt to the size of the incision for fixation, enabling the concave tube 1 to realize the automatic expansion function, ensuring that the protection of the concave tube 1 for the incision is always completely adapted, and at the same time the protection component 2 can automatically fix one end of the concave tube 1. The operation is simple and fast, reducing the preparation time of surgical instruments and improving the surgical efficiency. Without using electronic components for transmission, the structure is more reliable and the failure rate is reduced.Turn on the suction component 4 and start working. The suction component 4 realizes the function of continuously absorbing harmful smoke generated by the operation of the energy device during the operation. Moreover, through the setting of the suction component 4, the suction force can be flexibly adjusted to meet different smoking power requirements.

[0034] like Figure 2 、 Figure 6 、 Figure 7 、 Figure 12 As shown, the air intake assembly 4 also includes a bracket 417 fixed on the mounting frame 42, a cylinder 418 fixed on the bracket 417, a piston 419 slidingly arranged in the cylinder 418, a third connecting rod 420 with one end rotatably arranged on the piston 419 and the other end rotatably arranged on the first connecting rod 45, an air inlet 421 arranged on the cylinder 418, an exhaust port 422 arranged on the cylinder 418, a first one-way valve 423 arranged in the air inlet 421, a second one-way valve 424 arranged on the exhaust port 422, and a purifier 425 fixedly arranged at one end of the exhaust port 422. When in use, the motor 41 is turned on and starts working, driving the first rotating shaft 43 to rotate, driving the eccentric shaft 44 to rotate, thereby driving the first connecting rod 45 to move, and then driving the third connecting rod 420 to move, and finally driving the piston 419 to reciprocate up and down. When the piston 419 moves downward, negative pressure is formed in the cylinder 418, the first one-way valve 424 opens, and the second one-way valve 425 closes, and the suction work is performed. When the piston 419 moves upward, the space in the cylinder 418 is compressed, the second one-way valve 425 opens, and the first one-way valve 424 closes, and the exhaust work is performed. The smoke is discharged after passing through the purifier 425. When in use, by rotating the operating lever 413, the second gear 414 is driven to rotate, thereby driving the first gear 412 to rotate, and then driving the threaded rod 411 to rotate, thereby driving the second rotating shaft 49 to move, thereby driving the second connecting rod 46 to move, and finally driving the first connecting rod 45 to rotate, thereby changing the distance the piston 419 travels back and forth each time, thereby achieving the function of changing the suction power. When in use, the operating rod 413 is fixed by the fixing assembly 415. When the operating rod 413 rotates, the ball 4155 compresses the fixing spring 4154, disengages from the small hole 4151, and releases the restriction, allowing the operating rod 413 to rotate. When rotating to the next small hole 4151, the fixing spring 4154 rebounds, and the ball 4155 re-enters the small hole 4151 to complete the restriction and fix the operating rod 413.

[0035] like Figure 7As shown, the eccentric shaft 44 is a U-shaped shaft. One end of the first connecting rod 45 is arranged on the eccentric shaft 44, and a relief groove is provided at the other end. A short rod is fixedly arranged on the relief groove. The second connecting rod 46 and the third connecting rod 420 are simultaneously rotatably arranged on the short rod, and a gap is left between the second connecting rod 46 and the third connecting rod 420. The first one-way valve 423 is disposed in the air inlet 421 in the forward direction, and the second one-way valve 424 is disposed in the exhaust port 422 in the reverse direction.

[0036] As Figure 2 , Figure 8 As shown, the connection component 3 includes a communication pipe 31 fixedly arranged at one end on the air inlet 421, a fixed joint 32 fixedly arranged at one end of the communication pipe 31, a mounting joint 33 rotatably sleeved on the fixed joint 32, a threaded joint 34 fixedly arranged on the mounting joint 33, a smoking pipe 35 fixedly arranged on the protection component 2, a fixed plug 36 fixedly arranged at one end of the smoking pipe 35, a threaded plug 37 fixedly arranged on the fixed plug 36, a magnifying pipe 38 slidably arranged on the threaded plug 37, a first spring 39 fixedly arranged on the fixed joint 36, a first magnifying ball 310 fixedly arranged on the first spring 39, a second spring 310 fixedly arranged in the fixed plug 36, and a second magnifying ball 311 fixedly arranged on the second spring 310. When in use, rotate the threaded joint 34 to fix the threaded joint 34 and the threaded plug 37. During the process of the threaded plug 37 entering the threaded joint 34, the magnifying pipe 38 is driven to move forward, and at the same time, it contacts the first magnifying ball 310 and the second magnifying ball 311, thereby compressing the first spring 39 and the second spring 310, and making the magnifying pipe 38 connect the communication pipe 31 and the smoking pipe 35 to complete the fixation.

[0037] As shown in Figure 2 , Figure 8 As shown, the magnifying pipe 38 is provided with a convex ring 381, and the threaded plug 37 is provided with a circular ring 371. The inner diameter of the magnifying pipe 38 is smaller than the inner diameters of the communication pipe 31 and the fixed joint 32. The diameter of the convex ring 381 on the magnifying pipe 38 is larger than the diameter of the circular ring 371 and the diameter of the convex ring 381 is also larger than the inner diameter of the fixed plug 36. The diameter of the first magnifying ball 310 is larger than the inner diameter of the mounting joint 33, and the diameter of the second magnifying ball 311 is larger than the inner diameter of the fixed plug 36. The outer surface of the threaded plug 37 is provided with threads, and the inner surface of the threaded joint 34 is provided with threads. The threaded plug 37 and the threaded joint 34 are connected by threads. By changing the diameter of the channel, the diameter of the pipe near the suction component 4 is made larger than that of the other end, so as to achieve the effect of increasing the suction force of the smoking pipe 35.

[0038] As Figure 5 , Figure 13As shown, the protection component 2 includes a connection block 21 fixedly connected to the smoking pipe 35, a through hole 22 provided on the connection block 21, a deep hole 23 provided on the connection block 21, a rotating rod 24 rotatably provided in the deep hole 23, a fixed rod 25 fixedly provided on the rotating rod 24, a driving groove 26 provided in the connection block 21, a groove 27 provided on the connection block 21, a third rotating shaft 28 rotatably provided in the driving groove 26, a third gear 29 fixedly provided on the third rotating shaft 28, a torsion spring 210 fixedly provided on the third rotating shaft 28, and a clamping component 211 provided in the connection block 21; one end of the torsion spring 210 is fixed on the third rotating shaft 28 and the other end is provided in the groove 27, and the torsion spring 210 is located at the middle position of the groove 27. When in use, one end of the concave pipe 1 is inserted into the deep hole 23. During the insertion process, the fixed rod 25 is driven to rotate. When the fixed rod 25 rotates to a position perpendicular to the inner wall of the deep hole 23, the concave pipe 1 is squeezed in cooperation with the deep hole 23, so as to achieve the fixing effect. The other end of the concave pipe 1 passes through the through hole 22, forming a smaller ring for the concave pipe 1. When the concave pipe 1 passes through the through hole 22, the third gear 29 is driven to rotate, thereby driving the third rotating shaft 28 to rotate, and then driving the torsion spring 210 to rotate. When the concave pipe 1 enters a sufficient length, the clamping component 211 is operated to fix it. Then the small ring is placed on the incision, and the clamping component 211 is opened to release the fixation. At this time, the torsion spring 210 rebounds, driving the third rotating shaft 28 to rotate in the reverse direction, driving the third gear 29 to rotate in the reverse direction, so that the concave pipe 1 gradually withdraws from the through hole 22, and the small ring gradually enlarges into a large ring until it fits the incision, protecting and fixing the incision, and then the clamping component 211 is operated to fix it.

[0039] As Figure 5 , Figure 13 shown, the clamping component 211 includes a fourth rotating shaft 2111 rotatably provided through the connection block 21, a fourth gear 2112 fixedly provided on the fourth rotating shaft 2111, a first rack 2113 slidably provided in the through hole 22, a second rack 2114 slidably provided in the through hole 22, a first clamping rod 2115 fixedly provided at one end of the first rack 2113, and a second clamping rod 2116 fixedly provided at one end of the second rack 2114; the first rack 2113 and the second rack 21 receive the same time, and are meshed with the fourth gear 2112 and are arranged in a mirror image. The clamping component 211 is provided at one end of the connection block 21 and is located directly above the through hole 22. When in use, the fourth rotating shaft 2111 is rotated, thereby driving the fourth gear 2112 to rotate, thereby driving the first rack 2113 and the second rack 2114 to move in the reverse direction, thereby driving the first clamping rod 2115 and the second clamping rod 2116 to move in the reverse direction to complete the clamping work.

[0040] As Figure 3As shown, the concave tube 1 includes a tube body 11, a plurality of concave teeth 12 arranged at equal intervals in a linear array on the upper surface of the tube body 11, and a plurality of reinforcing ribs 13 arranged at equal intervals in a linear array inside the tube body; one end of the tube body enters the deep hole and the other end passes through the through hole; the concave tube 1 is made of non-toxic and soft silica gel material, and the third gear 29 and the concave teeth 12 are meshed.

[0041] When the present invention is in use, first operate the connecting component 3 to fix the protection component 2 and the air suction component 4 together. Rotate the threaded joint 34 to fix the threaded joint 34 and the threaded plug 37. During the process of the threaded plug 37 entering the threaded joint 34, it drives the amplifying tube 38 to move forward, and at the same time contacts the first amplifying ball 310 and the second amplifying ball 311, thereby compressing the first spring 39 and the second spring 310, making the amplifying tube 38 communicate with the connecting pipe 31 and the smoking pipe 35 to complete the fixation. The connection is made through threads, which is convenient for the disassembly and fixation of the entire device, and at the same time ensures good fixation effect and sealing efficiency, preventing the situation of unreliable fixation affecting the use, and at the same time preventing the occurrence of smoke overflow due to poor sealing. Then operate the concave tube 1 to insert one end into the deep hole 23. During the insertion process, it drives the fixing rod 25 to rotate. When the fixing rod 25 rotates to a position perpendicular to the inner wall of the deep hole 23, it cooperates with the deep hole 23 to squeeze the concave tube 1, thereby achieving the fixation effect. The other end of the concave tube 1 passes through the through hole 22, making the concave tube 1 form a smaller ring. When the concave tube 1 passes through the through hole 22, it drives the third gear 29 to rotate, thereby driving the third rotating shaft 28 to rotate, and then driving the torsion spring 210 to rotate. When the concave tube 1 enters a sufficient length, operate the clamping component 211 to fix it. Then place the small ring on the incision, and then open the clamping component 211 to release the fixation. At this time, the torsion spring 210 rebounds, driving the third rotating shaft 28 to rotate in the reverse direction, driving the third gear 29 to rotate in the reverse direction, so that the concave tube 1 gradually exits the through hole 22, and the small ring gradually expands into a large ring until it fits the incision, protecting and fixing the incision, and then operate the clamping component 211 to fix it. The automatic expansion function of the concave tube 1 is realized, so that the concave tube 1 can automatically adapt to the size of the incision for fixation, ensuring that the protection of the concave tube 1 to the incision is always completely adapted. The operation is simple and fast, reducing the preparation time of surgical instruments and improving the surgical efficiency. It does not use electronic components for transmission, making the structure more reliable and reducing the failure rate. Open the air suction component 4 to start working. Start the motor 41 to work, drive the first rotating shaft 43 to rotate, drive the eccentric shaft 44 to rotate, thereby driving the first connecting rod 45 to move, and then drive the third connecting rod 420 to move, and finally drive the piston 419 to perform reciprocating up and down movements. When the piston 419 moves downward, a negative pressure is formed in the cylinder 418, the first one-way valve 424 opens, and the second one-way valve 425 closes to perform the air suction work. When the piston 419 moves upward, it compresses the space in the cylinder 418, the second one-way valve 425 opens, and the first one-way valve 424 closes to perform the exhaust work. The smoke is discharged after passing through the purifier 425. When in use, by rotating the operating rod 413, it drives the second gear 414 to rotate, thereby driving the first gear 412 to rotate, and then driving the threaded rod 411 to rotate, thereby driving the second rotating shaft 49 to move, and then driving the second connecting rod 46 to move, and finally driving the first connecting rod 45 to rotate, thereby changing the distance of each reciprocation of the piston 419 and realizing the function of changing the air suction power.When in use, the operating rod 413 is fixed by the fixing component 415. When the operating rod 413 rotates, the small ball 4155 compresses the fixing spring 4154 and disengages from the small hole 4151, releasing the restriction, enabling the operating rod 413 to rotate. When it rotates to the next small hole 4151, the fixing spring 4154 rebounds, and the small ball 4155 re-enters the small hole 4151 to complete the restriction and fix the operating rod 413. The suction component 4 realizes the function of continuously absorbing harmful smoke generated by the energy instrument during the operation, and through the setting of the suction component 4, the suction force can be flexibly adjusted according to different smoking power requirements.
