Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a medical incision protector. Background Art

[0002] During surgery, after the doctor makes an incision at the surgical site of the patient, the incision will be in a closed state due to the contraction of the tissue. In order to perform the operation, the incision needs to be stretched and expanded. To ensure a good incision support effect, the incision protection cover needs to be made of a harder material, but this will result in less elasticity and a reduced effective expansion area after being inserted into the incision, affecting the doctor's field of vision and operating space. If the incision protection cover is made of a softer material, although it can be easily inserted into the incision, it does not have sufficient rigidity to support the incision.

[0003] The existing patent (publication number: CN110236611A) discloses a medical incision expansion protective sleeve, comprising an expansion support (1), an upper cover (2) and a one-way valve device (3), wherein the upper cover (2) covers the top of the expansion support (1) and can prevent foreign matter from falling during surgery or other operations, thereby protecting the tissue in the incision; the one-way valve device (3) is installed at the air inlet position of the expansion support (1); the expansion support (1) is hollow inside, with a sandwich structure with expanded openings at both ends and gradually narrowed toward the middle; the expansion support (1) is a flexible body, and the side wall sandwich of the expansion support (1) can be inflated, and the side wall sandwich of the expansion support (1) is connected to the one-way valve device (3) through the air inlet position. The design of the present invention is easy to be placed in a surgical incision, easy to be taken out, and convenient to operate.

[0004] The above patented technology has sufficient rigidity after inflation and can freely control the expansion range of the epidermal tissue to meet the use requirements. However, in actual use, its inner diameter can change within a certain range after inflation. However, the above protective sleeve is annular. Since the incisions during surgery are mostly long strips, it is not convenient to adjust the expansion openings on both sides according to actual needs during use. When the expansion degree is large, it may cause the incision to split, and when the expansion degree is small, it affects the doctor's field of vision and operating space. Therefore, a medical incision protector is proposed. Summary of the invention

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1:

[0033] Please refer to Figure 1-Figure 4 and Figure 8 The present invention provides a technical solution: a medical incision protector comprises two side seats 1 and an adjusting box 2, a transmission shaft 3 is rotatably connected between the opposite inner surfaces on the front and rear sides of the adjusting box 2, a rotating shaft 4 is rotatably penetrated through the top outer surface of the adjusting box 2, a turntable 28 is fixedly connected to the top outer surface of the rotating shaft 4, a driving bevel gear 5 is fixedly sleeved on the bottom outer surface of the rotating shaft 4, a driven bevel gear 6 is fixedly sleeved on the outer surface of the transmission shaft 3, and the driving bevel gear 5 is movably meshed with the outer surface of the driven bevel gear 6, two connecting shafts 7 are rotatably connected between the opposite inner surfaces on the front and rear sides of the adjusting box 2, the two connecting shafts 7 are respectively located on the left and right sides of the transmission shaft 3, a driving gear 8 is fixedly sleeved on the outer surface of the transmission shaft 3, a driven gear 9 is fixedly sleeved on the outer surfaces of the two connecting shafts 7, the driving gears 8 are movably meshed with the outer surfaces of the two driven gears 9, the outer surfaces of the two connecting shafts 7 are fixedly sleeved with a winding wheel 10, and a winding rope 11 is wound around the outer surfaces of the two winding wheels 10. The turntable 28 rotates, and the turntable 28 drives the rotating shaft 4 to rotate, and the driving bevel gear 5 rotates, and the driving bevel gear 5 drives the driven bevel gear 6 to rotate the transmission shaft 3. When the transmission shaft 3 rotates, it drives the driving gear 8 thereon to rotate, and the driving gear 8 drives the driven gear 9 to rotate the connecting shaft 7. When the connecting shaft 7 rotates, the winding rope 11 is wound or discharged, thereby adjusting the distance between the two side seats 1.

[0034] A U-shaped rod 29 is movably inserted on the outer surface of the turntable 28 from top to bottom, and the top outer surface of the adjusting box 2 is located at the periphery of the rotating shaft 4 and is fixedly connected to a limit plate 27. The outer surface of the limit plate 27 is provided with a plurality of limit holes 31 in a circular array that are compatible with the two vertical rods of the U-shaped rod 29. A sleeve disc 30 is fixedly sleeved on the two vertical rods of the U-shaped rod 29. The top outer surfaces of the two sleeve discs 30 are fixedly connected to first springs 36. The top outer surface of the first spring 36 is fixedly connected to the bottom outer surface of the turntable 28, and the two first springs 36 are respectively sleeved on the outer surfaces of the two vertical rods. Pull the U-shaped rod 29 upwards, and the U-shaped rod 29 drives the sleeve 30 to move upwards, so that the second spring 37 is compressed, and the U-shaped rod 29 is disengaged from the inside of the limiting hole 31, releasing the limit on the turntable 28, so that rotating the U-shaped rod 29 can drive the turntable 28 to rotate. After the adjustment is completed, stop applying force to the U-shaped rod 29, and drive the U-shaped rod 29 to insert into the limiting hole 31 under the elastic force of the first spring 36 to limit the turntable 28.

[0035] The outer surfaces of both sides of the regulating box 2 are fixedly connected with fixed rods 32, and the inner surfaces of the four fixed rods 32 are fixedly connected with third springs 33. A movable rod 34 is movably inserted inside the fixed rods 32, and one end of the movable rod 34 is fixedly connected to the third spring 33, and the other end of the movable rod 34 away from the third spring 33 is fixedly connected to the outer surface of the connecting plate. When the distance between the two side seats 1 needs to be adjusted closer, the movable rod 34 is moved inside the fixed rod 32 and the third spring 33 is compressed. When the distance between the two side seats 1 needs to be adjusted farther, when the winding rope 11 is spit out, the resetting force of the third spring 33 is cooperated to tighten the winding rope 11.

[0036] A telescopic tube 18 is fixedly connected between the two delivery tubes 17, and a telescopic rod 35 is fixedly connected between the opposite outer surfaces of the two rear connection plates. When the distance between the two side seats 1 is adjusted, the telescopic tube 18 and the telescopic rod 35 are extended and retracted accordingly, and the telescopic tube 18 does not affect the delivery of gas between the delivery tubes 17, and the telescopic rod 35 supports the other ends of the two side seats 1.

[0037] The winding directions of the winding ropes 11 on the surfaces of the two winding wheels 10 are opposite. The driving gear 8 drives the driven gear 9 to rotate, so that the two connecting shafts 7 rotate in the same direction. Because the two winding ropes 11 are located on both sides, when the distance between the two side seats 1 and the adjustment box 2 needs to be adjusted, the two winding wheels 10 are required to simultaneously wind up or spit out the winding ropes 11. The winding directions of the two winding ropes 11 are opposite, so when the winding wheels 10 rotate, the two winding wheels 10 can be driven to wind up or spit out the winding ropes 11 simultaneously.

[0038] In the specific implementation process, during the operation, the medical staff makes an incision, and fixes the incision with commonly used sanitary clips on both sides of the incision along the incision direction to prevent the incision from splitting along the incision direction. In advance, according to the size of the incision, the U-shaped rod 29 is pulled upward, and the U-shaped rod 29 drives the sleeve disc 30 to move upward, so that the second spring 37 is compressed, and the U-shaped rod 29 is disengaged from the inside of the limiting hole 31, and the limit on the turntable 28 is released, and then the U-shaped rod 29 is rotated, so that the U-shaped rod 29 drives the turntable 28 to rotate, and the turntable 28 drives the rotating shaft 4 to rotate, and the active bevel gear 5 rotates, and the active bevel gear 5 drives the driven bevel gear 6 to rotate the transmission shaft 3 When the transmission shaft 3 rotates, the driving gear 8 thereon is driven to rotate, and the driving gear 8 drives the driven gear 9 to rotate the connecting shaft 7. When the connecting shaft 7 rotates, the winding rope 11 is wound or spit out, thereby adjusting the distance between the two side seats 1. When the two side seats 1 move, the movable rod 34 moves in the fixed rod 32, so that the third spring 33 is deformed, and then the device is placed in the incision, so as to facilitate the adjustment of the position between the two side seats 1 according to the length of the incision. After the adjustment is completed, the force on the U-shaped rod 29 is stopped, and the U-shaped rod 29 is driven to be inserted into the limiting hole 31 under the elastic force of the first spring 36 to limit the rotating disk 28.

[0039] Embodiment 2:

[0040] Please refer to Figure 1 , Figure 6-Figure 7 The present invention provides a technical solution: a cylindrical airbag 12 is provided on the inner surface of each of the two side seats 1, a sleeve rod 13 is movably inserted into the outer surfaces of the front and rear sides of the two side seats 1, and the outer surfaces of the four sleeve rods 13 are fixedly connected with connecting plates, the other ends of the two winding ropes 11 are respectively fixedly connected to the outer surfaces of the two front connecting plates, and one end of the sleeve rod 13 located on the outer surface of the side seat 1 is fixedly connected with a support plate 14, an air intake pipe 15 is fixedly inserted into the outer surface of the top of the left side seat 1, and an air deflation pipe 16 is fixedly connected to the outer surface of the air intake pipe 15, one end of the air intake pipe 15 is fixedly connected to the interior of the cylindrical airbag 12, and a delivery pipe 17 is fixedly connected to the opposite outer surfaces of the two side seats 1, the left delivery pipe 17 is fixedly connected to the interior of the air intake pipe 15, and the right delivery pipe 17 is fixedly connected to the interior of the right cylindrical airbag 12.

[0041] The inner surfaces of the left and right sides of the side seat 1 are fixedly connected with elastic ropes, and the elastic ropes are fixedly connected to the outer surfaces of the cylindrical airbags 12. The cylindrical airbags 12 are supported by the elastic ropes.

[0042] The inner surfaces of both the front and rear sides of the side seat 1 are fixedly connected with a second spring 37, which is sleeved on the outer surface of the sleeve rod 13, and a disc is fixedly sleeved on the outer surface of the sleeve rod 13, and the other end of the second spring 37 is fixedly connected to the disc. When the operation is completed, the deflation pipe 16 is connected to discharge the gas, and the sleeve rod 13 is driven by the elastic force of the second spring 37 to reset the support plate 14.

[0043] During the specific implementation process, when the device is placed in the incision, the support plate 14 is placed in a position perpendicular to the incision and placed in the incision, and then according to the required expansion range, the air inlet pipe 15 is inflated through an external pressure device, the gas enters the delivery pipe 17, and the cylindrical airbag 12 is expanded. The expansion force of the cylindrical airbag 12 overcomes the force of the second spring 37, so that the sleeve rod 13 moves outward, and the support plate 14 is stretched to open the incision through the movement of the sleeve rod 13. According to the required expansion size, the amount of air filled into the cylindrical airbag 12 is controlled. When the operation is completed, the deflation pipe 16 is connected to discharge the gas, and the sleeve rod 13 is driven by the elastic force of the second spring 37 to reset the support plate 14, so that the expansion degree of the incision can be controlled according to actual needs.

[0044] Embodiment 3:

[0045] Please refer to Figure 4-Figure 5 and Figure 9-10 The present invention provides a technical solution: two storage boxes 19 arranged symmetrically in front and back are fixedly connected at the ends of the top outer surfaces of the two side seats 1, and a box door is provided on the outer surface of the storage box 19. A horizontal shaft 20 is rotatably connected between the inner surfaces of the left and right sides of the storage box 19, and the other end of the horizontal shaft 20 rotates and penetrates the outer surface of the storage box 19. A knob 21 is fixedly connected to one end of the horizontal shaft 20 located outside the storage box 19, and a winding roller 22 is fixedly sleeved on the outer surface of the horizontal shaft 20, and a fixed cloth 23 is wound around the outer surface of the winding roller 22. The storage box 19 can be opened by the provided box door, and the fixed cloth 23 can be replaced after the fixed cloth 23 is used up.

[0046] A ratchet 24 is fixedly sleeved on the outer surface of the horizontal axis 20, and a ratchet 25 is rotatably connected to the inner surface of the storage box 19. The ratchet 25 is movably engaged with the outer surface of the ratchet 24. A pull rope 26 is fixedly connected to the outer surface of the ratchet 25, and the pull rope 26 movably penetrates the outer surface of the storage box 19. The ratchet 25 and the ratchet 24 cooperate to make the horizontal axis 20 only unidirectionally rotatable. Pulling the pull rope 26 makes the horizontal axis 20 rotatable in both directions. After the fixed cloth 23 is rolled up to a suitable length, the pull rope 26 is released, and the ratchet 25 falls due to gravity and is stuck at the ratchet teeth of the ratchet 24 to limit it.

[0047] In the specific implementation process, when the device is placed at the incision, the fixing cloth 23 is pulled outward. When pulled, the horizontal axis 20 is rotated. Under the action of the pawl 25 and the ratchet 24, the horizontal axis 20 is prevented from rotating in the other direction. After the fixing cloth 23 is stretched to a suitable position, the fixing cloth 23 is fixed to the patient's skin with medical tape, thereby positioning the device. After the operation is completed, the fixed end of the fixing cloth 23 is cut off, and the pull rope 26 is pulled upward to make the pawl 25 detach from the surface of the ratchet 24, so that the horizontal axis 20 can rotate in the other direction, thereby rolling up the excess fixing cloth 23. After it is rolled up to a suitable length, the pull rope 26 is released, and the pawl 25 falls due to gravity and is stuck on the ratchet teeth of the ratchet 24 to limit it.

[0048] Working principle: During the actual use of the present invention, during surgery, medical staff make an incision, and fix the incision along the incision direction with commonly used sanitary clips on both sides to prevent the incision from splitting along the incision direction. In advance, according to the size of the incision, the U-shaped rod 29 is pulled upward, and the U-shaped rod 29 drives the sleeve 30 to move upward, so that the second spring 37 is compressed, and the U-shaped rod 29 is disengaged from the inside of the limiting hole 31, and the limit on the turntable 28 is released, and then the U-shaped rod 29 is rotated, so that the U-shaped rod 29 drives the turntable 28 to rotate, and the turntable 28 drives the rotating shaft 4 to rotate, and the active bevel gear 5 rotates, and the active bevel gear 5 drives the driven bevel gear 6 to make the transmission The driving shaft 3 rotates, and when the transmission shaft 3 rotates, the driving gear 8 thereon is driven to rotate, and the driving gear 8 drives the driven gear 9 to rotate the connecting shaft 7. When the connecting shaft 7 rotates, the winding rope 11 is wound or spit out, thereby adjusting the distance between the two side seats 1. When the two side seats 1 move, the movable rod 34 moves in the fixed rod 32, so that the third spring 33 is deformed, and then the device is placed in the incision, so as to facilitate the adjustment of the position between the two side seats 1 according to the length of the incision. After the adjustment is completed, the force on the U-shaped rod 29 is stopped, and the U-shaped rod 29 is driven to be inserted into the limiting hole 31 under the elastic force of the first spring 36 to limit the rotating disk 28.

[0049] When the device is placed in the incision, the support plate 14 is placed in a position perpendicular to the incision and placed in the incision. Then, according to the required expansion range, air is inflated into the air inlet pipe 15 through an external pressure device. The gas enters the delivery pipe 17 and expands the cylindrical airbag 12. The expansion force of the cylindrical airbag 12 overcomes the force of the second spring 37, so that the sleeve rod 13 moves outward. The movement of the sleeve rod 13 causes the support plate 14 to expand the incision. According to the required expansion size, the amount of air inflated into the cylindrical airbag 12 is controlled. When the operation is completed, the deflation pipe 16 is connected to discharge the gas. Under the elastic force of the second spring 37, the sleeve rod 13 is driven to reset the support plate 14, so that the expansion degree of the incision can be controlled according to actual needs.

[0050] When the device is placed at the incision, the fixing cloth 23 is pulled outward. When pulled, the horizontal axis 20 rotates. Under the action of the pawl 25 and the ratchet 24, the horizontal axis 20 is prevented from rotating in the other direction. After the fixing cloth 23 is stretched to a suitable position, the fixing cloth 23 is fixed to the patient's skin with medical tape to position the device. After the operation is completed, the fixed end of the fixing cloth 23 is cut off, and the pull rope 26 is pulled upward to make the pawl 25 detach from the surface of the ratchet 24, so that the horizontal axis 20 can rotate in the other direction, thereby rolling up the excess fixing cloth 23. After it is rolled up to a suitable length, the pull rope 26 is released, and the pawl 25 falls due to gravity and is stuck on the ratchet teeth of the ratchet 24 to limit it.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
