Description

Technical Field

[0001] This utility model relates to a protective device, specifically a protective device for preventing secondary damage to abdominal skin tissue during minimally invasive surgery. Background Technology

[0002] Traditional minimally invasive abdominal surgery involves inserting an endoscope directly into the abdominal cavity through a skin incision. The surgeon rotates the endoscope to change the field of view. Because the surgeon needs to constantly rotate the endoscope to examine the lesion, the outer tube of the endoscope comes into direct contact with the skin tissue. During the rotation, it rubs against the abdominal incision, which can easily cause secondary damage to the epidermal tissue. Summary of the Invention

[0003] The purpose of this invention is to provide a protective device for preventing secondary damage to abdominal skin tissue during minimally invasive surgery, which can avoid direct contact between the endoscope and skin tissue and effectively prevent secondary damage to skin tissue caused by back-and-forth friction.

[0004] To achieve the above objectives, the technical solution of this utility model is: a protective device to prevent secondary damage to abdominal skin tissue during minimally invasive surgery, the innovation of which lies in: including a protective sleeve, a valve connector, and a leak-proof connection mechanism.

[0005] The protective sleeve has a protective channel that facilitates the insertion of the endoscope and allows for easy adjustment within it.

[0006] The leak-proof connection mechanism includes a connecting body, a main body rear seat, a magnetic sheet, a magnet, and a sealing cap. The connecting body is fitted onto the outer periphery of the tail of the protective sleeve. One end of the main body rear seat is inserted into the interior of the connecting body and sealed thereto. The other end of the main body rear seat is provided with a sealing cap. The magnetic sheet is located inside the main body rear seat, and the magnet is located on the outer periphery of the main body rear seat.

[0007] The air inlet of the air valve connector is used to connect with the air supply device, and the air outlet of the air valve connector is connected to the connecting body. The air supply device fills the protective channel of the protective sleeve with air through the air valve connector.

[0008] When the endoscope is inserted into the protective channel of the protective sleeve, the magnetic plate flips over, and a sealed connection is formed between the outer diameter of the endoscope and the sealing cap to prevent gas leakage. When the endoscope is pulled out of the protective sleeve, the magnetic plate flips over again under the magnetic attraction of the magnet and automatically attracts it, so that the interior of the main body rear seat is isolated from the external environment under the action of the magnetic plate to prevent gas leakage.

[0009] In the above technical solution, the connecting body includes a sleeve connecting section and a rear seat connecting section that are integrated together. The sleeve connecting section is fitted onto the outer periphery of the tail of the protective sleeve, and the air outlet end of the air valve connector is connected to the sleeve connecting section. One end of the rear seat of the main body is inserted into the interior of the rear seat connecting section and is detachably connected to it.

[0010] In the above technical solution, the main body rear seat includes a main body connecting section, a magnet connecting section, and a sealing cap connecting section that are integrated together. The main body connecting section is inserted into the interior of the connecting body and is sealed to it. At the same time, a magnetic sheet is disposed inside the main body connecting section. The outer periphery of the magnet connecting section is provided with a magnet mounting groove, and the magnet is snapped into the magnet mounting groove of the magnet connecting section. The sealing cap connecting section has a sealing cap positioning mounting groove, and the sealing cap is fitted onto the outer periphery of the sealing cap connecting section, with a portion of it disposed within the sealing cap positioning mounting groove.

[0011] In the above technical solution, the sealing cap has a wrapping part that can form a sealed connection with the outer diameter of the endoscope.

[0012] In the above technical solution, the outer periphery of the main body rear seat is also provided with a main body rear cover, and the main body rear cover covers the outside of the magnet.

[0013] In the above technical solution, the interior of the main body rear seat is provided with a magnetic sheet limiting groove, and the magnet is located in the magnetic sheet limiting groove.

[0014] The positive effects of this invention are: by using the protective device of this invention to prevent secondary damage to abdominal skin tissue during minimally invasive surgery, since this invention includes a protective sleeve, a valve connector, and a leak-proof connection mechanism,

[0015] The protective sleeve has a protective channel that facilitates the insertion of the endoscope and allows for easy adjustment within it.

[0016] The leak-proof connection mechanism includes a connecting body, a main body rear seat, a magnetic sheet, a magnet, and a sealing cap. The connecting body is fitted onto the outer periphery of the tail of the protective sleeve. One end of the main body rear seat is inserted into the interior of the connecting body and sealed thereto. The other end of the main body rear seat is provided with a sealing cap. The magnetic sheet is located inside the main body rear seat, and the magnet is located on the outer periphery of the main body rear seat.

[0017] The air inlet of the air valve connector is used to connect with the air supply device, and the air outlet of the air valve connector is connected to the connecting body. The air supply device fills the protective channel of the protective sleeve with air through the air valve connector.

[0018] When used in conjunction with an endoscope, this invention involves inserting one end of the protective sleeve into the skin incision. The endoscope rotates back and forth within the protective channel of the sleeve, avoiding direct contact with the skin incision. This avoids the drawback of existing technologies where the endoscope rubs against the skin incision due to rotation, causing secondary damage to the skin tissue. This invention isolates the endoscope from the skin incision tissue, reducing secondary damage and promoting positive wound healing.

[0019] Simultaneously, the air supply device inflates the abdomen through the air valve connector and protective sleeve, separating the abdomen from the abdominal cavity's visceral air to create a specific surgical operating space, facilitating better surgical procedures.

[0020] When the endoscope is inserted into the protective channel of the protective sleeve, the magnetic plate flips over, and a sealed connection is formed between the outer diameter of the endoscope and the sealing cap, preventing air leakage during abdominal inflation. When the endoscope is removed from the protective sleeve, the magnetic plate flips over again under the magnetic attraction of the magnet and automatically engages with it, isolating the interior of the main body's rear seat from the external environment. This prevents air leakage from reducing the surgical space in the abdominal cavity and thus affecting the operation.

[0021] Therefore, this invention not only avoids direct contact between the endoscope and skin tissue, effectively preventing secondary damage to the skin tissue caused by back-and-forth friction, but also effectively ensures that during the operation, whether the endoscope is inserted or withdrawn, gas will not leak and affect the surgical operating space, thus ensuring the safety of the surgical operation. Attached Figure Description

[0022] Figure 1 This is a structural schematic diagram of one specific embodiment of the present invention;

[0023] Figure 2 This is a schematic diagram of the state when this utility model is in use. Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and the given embodiments, but it is not limited thereto.

[0025] like Figure 1 , 2 As shown, a protective device for preventing secondary damage to abdominal skin tissue during minimally invasive surgery includes a protective sleeve 1, an air valve connector 2, and a leak-proof connection mechanism 3.

[0026] The protective sleeve 1 has a protective channel 11 that facilitates the insertion of the endoscope and allows for rotation and adjustment within it.

[0027] The leak-proof connection mechanism 3 includes a connecting body 31, a main body rear seat 32, a magnetic sheet 33, a magnet 34, and a sealing cap 35. The connecting body 31 is fitted onto the outer periphery of the tail of the protective sleeve 1. One end of the main body rear seat 32 is inserted into the interior of the connecting body 31 and sealed thereto. The other end of the main body rear seat 32 is provided with a sealing cap 35. The magnetic sheet 33 is located inside the main body rear seat 32, and the magnet 34 is located on the outer periphery of the main body rear seat 32.

[0028] The air inlet of the air valve connector 2 is used to connect with the air supply device, and the air outlet of the air valve connector 2 is connected to the connecting body 31. The air supply device fills the protective channel 11 of the protective sleeve 1 with air through the air valve connector 2.

[0029] When the endoscope is inserted into the protective channel 11 of the protective sleeve 1, the magnetic plate 33 is flipped, and a sealing connection is formed between the outer diameter of the endoscope and the sealing cap 35 to prevent gas leakage. When the endoscope is pulled out of the protective sleeve 1, the magnetic plate 33 flips again under the magnetic attraction of the magnet 34 and automatically attracts it, so that the interior of the main body rear seat 32 is isolated from the external environment under the action of the magnetic plate 33 to prevent gas leakage.

[0030] like Figure 1 As shown, in order to facilitate inflation and connection with the main body rear seat, making the structure more compact and reasonable, the connecting main body 31 includes a sleeve connecting section 311 and a rear seat connecting section 312 that are integrated together. The sleeve connecting section 311 is fitted onto the outer periphery of the tail of the protective sleeve 1, and the air outlet end of the air valve connector 2 is connected to the sleeve connecting section 311. One end of the main body rear seat 32 is inserted into the interior of the rear seat connecting section 312 and detachably connected to it.

[0031] Furthermore, such as Figure 1 As shown, in order to further improve the structural rationality and facilitate positioning and assembly, the main body rear seat 32 includes a main body connecting section 321, a magnet connecting section 322, and a sealing cap connecting section 323 that are integrated together. The main body connecting section 321 is inserted into the interior of the connecting body 31 and is sealed to it. At the same time, the magnetic sheet 33 is disposed inside the main body connecting section 321. The outer periphery of the magnet connecting section 322 is provided with a magnet mounting groove. The magnet 34 is snapped into the magnet mounting groove of the magnet connecting section 322. The sealing cap connecting section 323 has a sealing cap positioning mounting groove. The sealing cap 35 is fitted onto the outer periphery of the sealing cap connecting section 323, and a portion of it is disposed in the sealing cap positioning mounting groove.

[0032] Furthermore, such as Figure 1 As shown, in order to ensure that the sealing cap can form a good sealing structure with the endoscope and prevent air leakage, the sealing cap 35 has a wrapping part 351 that can form a sealing connection with the outer diameter of the endoscope.

[0033] Furthermore, such as Figure 1 , 2 As shown, in order to prevent the magnet from being contaminated, a main body rear cover 36 is also provided on the outer periphery of the main body rear seat 32, and the main body rear cover 36 covers the outside of the magnet 34.

[0034] Furthermore, such as Figure 1 , 2 As shown, in order to limit the magnetic sheet, the interior of the main body rear seat 32 is provided with a magnetic sheet limiting groove, and the magnet 33 is located in the magnetic sheet limiting groove.

[0035] When used in conjunction with an endoscope 4, this invention inserts one end of the protective sleeve 1 into the skin incision. The endoscope 4 rotates back and forth within the protective channel 11 of the protective sleeve 1, without direct contact with the skin incision. This avoids the drawback of existing technologies where the endoscope rubs against the skin incision due to reciprocating rotation, causing secondary damage to the skin tissue. This invention isolates the endoscope from the skin incision tissue, reducing secondary damage to the skin tissue and playing a positive role in the subsequent healing of the skin wound.

[0036] Simultaneously, the air supply device inflates the abdomen through the air valve connector 2 and the protective sleeve 1, separating the abdomen from the abdominal cavity visceral air to create a specific surgical operating space, facilitating better surgical procedures.

[0037] like Figure 2 As shown, when the endoscope 4 is inserted into the protective channel 11 of the protective sleeve 1, the magnetic sheet 33 is flipped over, and a sealed connection is formed between the outer diameter of the endoscope 4 and the sealing cap 35 to prevent air leakage during abdominal inflation. Figure 1 As shown, after the endoscope 4 is removed from the protective sleeve 1, the magnetic plate 33 flips again and is attracted to the magnet 34, thus isolating the interior of the main body rear seat 32 from the external environment under the action of the magnetic plate. This prevents the surgical space formed in the abdominal cavity from being reduced due to air leakage, which could affect the operation.

[0038] Therefore, this invention not only avoids direct contact between the endoscope and skin tissue, effectively preventing secondary damage to the skin tissue caused by back-and-forth friction, but also effectively ensures that during the operation, whether the endoscope is inserted or withdrawn, gas will not leak and affect the surgical operating space, thus ensuring the safety of the surgical operation.

[0039] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
