Description

Technical Field

[0001] The utility model relates to the field of cervical surgical instruments, in particular to an airbag support structure for surgery. Background Art

[0002] During neck surgery, the surgical procedure needs to be performed between the superficial cervical fascia and the deep cervical fascia. Usually, the superficial cervical fascia and the deep cervical fascia need to be separated to allow enough space for the surgical procedure.

[0003] During existing surgeries, the superficial cervical fascia and the deep cervical fascia are usually separated through laparoscope first. To prevent the separated superficial cervical fascia and the deep cervical fascia from sticking together, gas is usually inflated between the two. By filling the space between the two with gas, the superficial cervical fascia and the deep cervical fascia are separated to form an operating space for surgery. During the inflation process, excessive carbon dioxide gas will remain between the patient's superficial cervical fascia and the deep cervical fascia, and it will take a long time to be discharged after the operation, which will affect the patient's physical recovery efficiency.

[0004] Therefore, the existing technology still needs to be improved and developed. Utility Model Content

Therefore, the compressed airbag can be clamped by the surgical instrument and passed from the chest cavity opening to the surgical site, thereby positioning the airbag between the superficial cervical fascia and the deep cervical fascia. The inflatable connector punctures the outside of the patient's neck at the corresponding position and enters between the superficial cervical fascia and the deep cervical fascia. It then docks with the airbag at that position. The external gas is connected to the internal airbag through the inflatable connector to supply gas to the airbag, causing it to expand. The inflated airbag is in an expanded state, at which point the airbag has a larger expansion area. The expanded airbag supports the superficial cervical fascia, and then the inflatable connector is pulled in a direction away from the deep cervical fascia, thereby moving the superficial cervical fascia away from the deep cervical fascia. This creates a larger space within which surgical instruments can operate smoothly. After the operation is completed, the airbag can be reversely inhaled, causing it to be compressed and removed smoothly. By replacing the existing method of directly inflating the airbag into the human body with airbag support, no air will remain in the patient's body, allowing the patient to recover faster and improving medical efficiency.

DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solutions and advantages of the present invention more clear and distinct, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0047] Directly injecting carbon dioxide gas into the surgical area is not only prone to causing subcutaneous emphysema, but the gas will remain under the skin above the neck after surgery, taking a long time to be absorbed by the body, affecting recovery efficiency. In addition, the flow rate of the injected gas is difficult to control, making medical operations difficult. If the gas pressure is too high, it will compress some veins in the surgical area that bleed less, causing bleeding in hidden blood vessels, making it difficult for doctors to detect bleeding. Therefore, the surgical airbag support structure of this application is proposed to solve the above problems. Specific embodiments are as follows:

[0048] like Figure 1 、 Figure 2 As shown, this embodiment proposes an airbag support structure for surgery, which mainly includes: an airbag component 200 and an inflatable connector 100. The airbag component 200 and the inflatable connector 100 are separately set before the operation. In the separated state, the airbag component 200 is in a compressed state, and the volume of the airbag component 200 in the compressed state is very small. The airbag component 200 is used to be placed between the superficial cervical fascia and the deep cervical fascia of the patient's neck in the contracted state. The inflatable connector 100 adopts a long rod needle shape, and the front end (lower end) can be set to a sharp needle shape to facilitate insertion into the skin. For the convenience of structural description, the axial direction of the long rod-shaped inflatable connector 100 is taken as the front-to-back direction, and the front end is the end inserted into the patient's body. During the operation, the inflatable connector 100 is used to penetrate the skin of the patient's neck and dock with the airbag component 200; the airbag component 200 is inflated by the air supply of the inflatable connector 100, and the inflated inflatable connector 100 is supported between the superficial cervical fascia and the deep cervical fascia, so that the superficial cervical fascia is moved away from the deep cervical fascia to form an operating space 250.

[0049] like Figure 1 、 Figure 2As shown, in this embodiment, the superficial cervical fascia is first separated from the deep cervical fascia through laparoscope to form a chamber. Before the operation, the airbag member 200 is in a compressed state. In this compressed state, the airbag member 200 is relatively small. During the operation, an opening is usually made in the chest cavity to allow surgical instruments to enter the patient's neck from the chest cavity. Therefore, the compressed airbag member 200 can be clamped by the surgical instruments and enter the surgical site (the chamber formed by the separation of the superficial cervical fascia and the deep cervical fascia) from the opening in the chest cavity, thereby positioning the airbag member 200 between the superficial cervical fascia and the deep cervical fascia. The outer side of the patient's neck corresponding to the position is punctured through the inflatable connector 100 to enter between the superficial cervical fascia and the deep cervical fascia, and docked with the airbag component 200 at this position. The external gas is connected to the internal airbag component 200 through the inflatable connector 100 to realize gas supply to the airbag component 200, thereby expanding the airbag component 200. The airbag component 200 in the expanded state is in the expanded state. At this time, the airbag component 200 has a large expansion area. The superficial cervical fascia is supported by the airbag component 200 in the expanded state, and the inflatable connector 100 is pulled in the direction away from the deep cervical fascia, thereby moving the superficial cervical fascia away from the deep cervical fascia, and creating a larger space between the superficial cervical fascia and the deep cervical fascia, so that surgical instruments can smoothly perform surgery in this space. Figure 8 As shown, the inflatable connector 100 can be pulled from the outside by a support frame 300. The external support frame 300 is connected to the edge of the operating table. After the inflatable connector 100 drives the airbag component 200 to pull the superficial cervical fascia away from the deep cervical fascia, the inflatable connector 100 is connected to the support frame 300 to make the support more stable. After the operation is completed, the airbag component 200 can be reversely inhaled, so that the airbag component 200 is in a compressed state and can be smoothly removed. This avoids the use of a method of filling gas between the two to form an operating space for the operation. By using the airbag support method instead of the existing method of directly inflating into the human body, the gas will not remain in the patient's body, so that the patient can recover faster and improve medical efficiency.

[0050] like Figure 2 、 Figure 4As shown, the airbag component 200 in this embodiment specifically includes: a connecting disc 210 and an airbag skin 220. The connecting disc 210 adopts a disc structure and is penetrated by a docking hole 211. The airbag skin 220 is provided with an inflation space 221 and is arranged around the connecting disc 210. The inflation space 221 is connected to the docking hole 211, thereby connecting the docking hole 211 with the inner cavity of the airbag skin 220. The airbag skin 220 can be adhesively fixed to the connecting disc 210, or it can be screwed to the connecting disc 210 via a gland, so that the edge of the airbag skin 220 is compressed and sealed by the gland. The inflation connector 100 is provided with an inflation hole 111, which is used to connect the docking hole 211 and the external inflation device. The air pipe of the external inflation device is connected to the inflation connector 100, so that the external inflation device supplies air to the inflation hole 111, and the gas enters the inflation space 221 of the airbag cortex 220 through the docking hole 211, thereby inflating the airbag cortex and causing the airbag cortex to expand and stretch.

[0051] like Figure 1 、 Figure 2 、 Figure 3 As shown, the airbag cortex expands and primarily extends in the left-right direction. When inflated, the airbag cortex 220 assumes an arched shape, with the connecting plate 210 located midway between the apex of the arch. For example, the airbag cortex 220 can assume an "eight" shape, causing the airbag element 200 to arch upward. In this specific structure, the vertical plane is a plane passing through the central axis of the inflatable connector 100 and the left-right direction. Because the airbag cortex expands in the left-right direction when inflated, the expanded portions on the left and right sides are tilted after expansion, forming a profile similar to an inverted parachute. The airbag cortex, when inflated, can pull the superficial cervical fascia outward on both sides. The arched structure provides more stable support and a large pulling area, effectively separating the superficial cervical fascia from the deep cervical fascia. The expanded surgical space 250 created by the inflated airbag cortex 220 is relatively large and stable, ensuring a stable surgical procedure.

[0052] like Figure 1 、 Figure 3 、 Figure 5As shown in the specific structure, the airbag cortex 220 has a left expansion portion 222 and a right expansion portion 223 in the inflated state. The left expansion portion 222 and the right expansion portion 223 are integrally arranged and connected to the connecting plate 210. The left expansion portion 222 and the right expansion portion 223 are designed to be curved in the left-right direction and also in the thickness direction. This provides the entire airbag cortex 220 with excellent support strength, achieving relatively convenient pulling of the superficial cervical fascia. In addition, a flexible tensioning band 224 is provided within the inflation space 221 of the airbag cortex 220. By providing the flexible tensioning band 224, the outer ends of the inflated airbag cortex 220 are pulled, causing the outer ends of the airbag cortex 220 to gather toward the center, thereby providing more stable support for the arched airbag member 200.

[0053] like Figure 2 、 Figure 3 As shown in the specific structure, flexible tie bands 224 are respectively provided inside the left expansion portion 222 and the right expansion portion 223. The flexible tie bands 224 are fixedly connected to the inner wall of the airbag skin 220 and bonded to the side wall of the connecting disk 210. The flexible tie bands 224 extend away from the connecting disk 210. In the expanded state, the flexible tie bands 224 have a triangular shape. Therefore, the flexible tie bands 224 can be used to gather the outer ends of the airbag skin 220 toward the center (the location of the connecting disk 210), thereby providing more stable support for the arched airbag member 200. Therefore, the flexible tie bands 224 limit the expanded shape of the airbag skin 220 and enhance the load-bearing capacity of the airbag skin 220. In this embodiment, multiple flexible tie bands 224 can be provided, and multiple flexible tie bands 224 are arranged around the connecting disk 210. The lengths of each flexible tie band 224 are different, adapted to the length of the airbag skin 220 in the direction in which they extend. The radially-shaped multiple flexible tension bands 224 pull the inflated airbag skin layer 220 so that the inflated airbag skin layer 220 maintains an arch shape, thereby improving the support strength and making the inflated arched airbag skin layer 220 less likely to be collapsed.

[0054] like Figure 2 、 Figure 3As shown, the airbag skin layer 220 forms an upper airbag layer 201 and a lower airbag layer 202 within the inflatable space 221, and the inflatable space 221 is formed between the upper airbag layer 201 and the lower airbag layer 202. In this embodiment, multiple flexible lacing bands 224 are arranged around the connecting plate 210 and fixedly connected to the upper airbag layer 201. In order to ensure that the lower airbag layer 202 can also form a stable support, a flexible pull wire 225 is further provided on the flexible tensioning belt 224. The flexible pull wire 225 can be a metal wire. One end of the flexible pull wire 225 is passed through the flexible tensioning belt 224, and the other end is fixed obliquely on the lower airbag layer 202, so that the lower airbag layer 202 is pulled on the upper airbag layer 201 through the flexible pull wire 225. Since the connecting plate 210 is pulled upward by the inflatable connector 100, the upper airbag layer 201 can support the superficial cervical fascia upward, and the upwardly supported upper airbag layer 201 pulls the flexible pull wire 225, so that the lower airbag layer 202 can also be pulled up. At the same time, in the inflated state, the lower airbag layer 202 is gathered toward the middle by the inclined flexible pull wire 225, thereby improving the support performance of the lower airbag layer 202, so that the lower airbag layer 202 can be stably supported on the deep cervical fascia.

[0055] like Figure 3 As shown, in this embodiment, a plurality of flexible pull lines 225 are provided on a flexible tensioning belt 224, and the plurality of flexible pull lines 225 are spaced apart in the direction from the outside to the center, and in the direction from the outside to the center of the connecting disk 210, the inclination angle of the flexible pull lines 225 gradually increases, and the flexible pull lines 225 near the connecting disk 210 are almost vertical. In this way, among the multiple connection points between the lower airbag layer 202 and the multiple flexible pull lines 225, the connection points that are farther away from the connecting disk 210 receive a greater horizontal component of tension. In this way, the connection points that are closer to the outer ends receive a greater horizontal pulling force toward the inside, thereby making the lower airbag layer 202 better gathered toward the middle by the inclined flexible pull lines 225, and the lower airbag layer 202 is not easily crushed, thereby significantly improving the support performance.

[0056] The airbag member 200 in this embodiment is in a long strip structure in the compressed state after being deflated, which makes it easy to roll up the airbag member 200. The rolled airbag member 200 is more convenient to put in and take out.

[0057] like Figure 2 、 Figure 4 、 Figure 5As shown, further, a slot 230 is provided on the connecting disk 210 in this embodiment, and the inflatable connector 100 specifically includes: an inflatable plug rod 110 and a hook 120. The inflatable hole 111 is provided on the inflatable plug rod 110, and the hook 120 is provided on the inflatable plug rod 110. The hook 120 is detachably embedded in the slot 230 to connect the inflatable hole 111 with the docking hole 211. In the specific structure, after the inflatable plug rod 110 is inserted into the human epidermis, it passes through the superficial cervical fascia and enters the slot 230 through the hook 120. The hook 120 is docked with the slot 230 by rotating the inflatable plug rod 110, thereby achieving a stable connection between the inflatable connector 100 and the connecting disk 210. Moreover, when the inflatable connector 100 and the connecting disk 210 are stably connected by docking the hook 120 with the slot 230 , the inflatable hole 111 on the inflatable plug rod 110 and the docking hole 211 on the connecting disk 210 can also be aligned to achieve communication.

[0058] like Figure 5 、 Figure 6 As shown, further, the card slot 230 in this embodiment specifically includes: a card entrance 231 and a limiting cavity 232. The card entrance 231 is provided on the surface of the connecting disk 210; the limiting cavity 232 is provided inside the connecting disk 210 and is connected to the card entrance 231, thereby forming an "L"-shaped slot structure. The hook 120 includes: a connecting boss 121 and a card platform 122. The connecting boss 121 is provided on the inflation plug 110, and the card platform 122 is connected to the connecting boss 121 and forms a matching groove 123 with the surface of the inflation plug 110; the card platform 122 and the connecting boss 121 form a "7"-shaped card hook 120 structure. The card platform 122 enters the limiting cavity 232 from the card entrance 231 through the rotation of the inflation plug 110, so that the inflation plug 110 is connected to the connecting disk 210. This structure can easily realize the docking and separation of the hook 120 and the slot 230, making the inflatable connector 100 and the airbag component 200 more convenient to use during surgery.

[0059] like Figure 2 、 Figure 5 As shown, in this embodiment, a central axis hole 240 is defined in the center of the connecting disk 210. The central axis hole 240 passes through the connecting disk 210, thereby connecting to the surgical space 250. An exhaust hole 130 is defined in the inflatable connector 100, which is used to connect the central axis hole 240 to an external aspirator. The external aspirator uses negative pressure to suck out smoke generated during surgery in the surgical space 250 in a timely manner, thereby preventing smoke from obstructing the surgeon's surgical field of view and ensuring a clear surgical field of view.

[0060] like Figure 2 、 Figure 3 、 Figure 7As shown, in addition, a suction tube 150 is telescopically arranged in the exhaust hole 130, and the suction tube 150 is connected to an external suction device. During the operation, the suction tube 150 passes through the central axis hole 240 and extends into the operating space. The waste liquid between the patient's superficial cervical fascia and the deep cervical fascia can be collected by the external suction device through the suction tube 150, so that the waste liquid in the operating area can be discharged in time, the surgical instruments will not be interfered with by the waste liquid, and the operation is convenient.

[0061] like Figure 2 、 Figure 3 As shown, the pipette 150 is retractably disposed at the central axis of the vent 130. When aspiration is required, the pipette 150 is controlled to extend downward, pass through the central axis hole 240, and enter the surgical space. When aspiration is not required, the pipette 150 can be controlled to retract upward into the vent 130 of the inflatable connector 100, without interfering with the surgical instruments in the surgical space.

[0062] like Figure 1 、 Figure 7 As shown, the end of the inflation rod 110 in this embodiment, away from the connection plate 210, is provided with an inflation connector 112 and an air suction connector 131. Both the inflation connector 112 and the air suction connector 131 are located on the side wall of the inflation rod 110. The inflation connector 112 is connected to the inflation hole 111, and is connected to an external inflation device through the inflation connector 112 to achieve the inflation function. The upper end of the central exhaust hole 130 can be closed and led out from the side to connect to the side air suction connector 131. The air suction connector 131 is connected to an external aspirator, thereby achieving the function of absorbing smoke. A small hole is still opened at the upper end of the exhaust hole 130, and a sealing ring 160 is provided on the wall of the small hole. A liquid suction tube 150 is embedded in the sealing ring 160. The upper end of the liquid suction tube 150 is connected to a flexible pipe. The flexible pipe is led out from the side wall of the inflation rod 110 and is used to connect to an external liquid suction device to achieve the liquid suction function. In order to achieve the extension and retraction of the pipette 150, a strip square hole 113 is opened at the upper end of the inflation rod 110. The strip square hole 113 extends a predetermined length in the up and down direction. A push handle 151 is fixed radially on the outer wall of the pipette 150. The push handle 151 is located in the strip square hole 113 and moves up and down. The part of the push handle 151 protruding from the outside of the strip square hole 113 drives the pipette 150 to move up and down in the inflation rod 110 through the push of the doctor, thereby achieving the up and down pushing of the pipette 150.

[0063] like Figure 7As shown, because the outer ring of pipette 150 is covered by sealing ring 160, friction is generated between the two. This friction keeps pipette 150 in place after the doctor releases his grip, preventing it from falling. Furthermore, the sealing effect of sealing ring 160 prevents the pipette 150 from being affected during the inhalation process. Once the doctor has pushed pipette 150 to the desired position, they only need to release their grip, and the position of pipette 150 will remain essentially unchanged, thus optimizing the structure.

[0064] like Figure 2 、 Figure 3 As shown, a flexible cladding 152 is provided at the lower end of the pipette 150, and the flexible cladding 152 still has a middle hole to ensure the smooth flow of the pipette 150. During the downward movement of the pipette 150 to absorb liquid, the flexible cladding 152 can protect the lower end of the pipette 150, so that the lower end of the pipette 150 is not easy to bruise the patient's deep cervical fascia and cause bleeding, which affects the operation.

[0065] like Figure 2 、 Figure 4 、 Figure 5 As shown, in this embodiment, the inflation hole 111 is formed on the side of the inflation rod 110, and the docking hole 211 is formed on the side of the central axis hole 240. After the inflation connector 100 and the airbag component 200 are docked, the inflation rod 110 is inserted into the central axis hole 240, so that the inflation hole 111 and the docking hole 211 are docked at the side. The larger area of ​​the side allows the hole to be larger, thereby increasing the air intake volume, thereby quickly inflating the airbag skin 220, allowing the airbag skin 220 to quickly expand to a predetermined state, thereby improving surgical efficiency.

[0066] like Figure 2 As shown, further, the central axis hole 240 in this embodiment is tapered; a docking portion 140 is provided at one end of the inflatable connector 100, and the docking portion 140 is tapered and embedded in the tapered central axis hole 240. The tapered central axis hole 240 is connected to the docking portion 140 at the front end. When the tapered docking portion 140 enters the central axis hole 240, it is guided and aligned by the tapered surface, so that the inflatable plug 110 and the connecting plate 210 can be connected more accurately, and the operation process is more convenient.

[0067] like Figure 4 As shown, to facilitate smooth penetration of the inflatable connector 100 through human skin, a chamfered surface 141 is provided at the front end of the docking portion 140, thereby forming a pointed tip. The front end of the inflatable connector 100 is relatively small. During penetration of the inflatable connector 100 through the skin, the inflatable connector 100 can first be opened in the skin, and then the pointed end of the docking portion 140 can be rotated and squeezed into the skin, thereby entering between the superficial cervical fascia and the deep cervical fascia.

[0068] like Figure 2 As shown, further, in this embodiment, the opening of the central axis hole 240 on the side away from the inflatable connector 100 is configured as a bell mouth 241. The bell mouth 241 can guide the waste liquid entering the central axis hole 240. During the liquid suction process, the suction force has a wide coverage area, so that the waste liquid can be more thoroughly sucked into the central axis hole 240 and discharged.

[0069] like Figure 2 、 Figure 4 、 Figure 7 As shown, in this embodiment, multiple docking holes 211 are provided, evenly distributed around the central axis of the connecting plate 210; correspondingly, multiple inflation holes 111 are provided. The design of multiple docking holes 211 and multiple inflation holes 111 improves inflation efficiency and increases air intake, thereby rapidly inflating the airbag skin 220 to a predetermined state, improving surgical efficiency.

[0070] like Figure 8 、 Figure 9 As shown, after the inflatable connector 100 and the airbag component 200 are docked and inflated, the inflatable connector 100 can continuously pull the internal airbag component 200 upward. This ensures that the airbag component 200 continuously pulls the superficial cervical fascia upward, moving the superficial cervical fascia away from the deep cervical fascia, forming a stable surgical space. In the specific structure, a support frame 300 is provided on the outside. The support frame 300 is connected to the operating table and can be placed across the patient's neck. A locking assembly 310 is provided on the support frame 300 to fix the inflatable connector 100. The inflatable connector 100 is connected to the locking assembly 310 and can be adjusted in the vertical direction on the locking assembly 310. When adjusted to the ideal position, the locking assembly 310 is used to limit and fix the inflatable connector 100 to the support frame 300, so that the inflatable connector 100 is fixed to the support frame 300 and positioned above the surgical site, pulling the airbag component 200 between the patient's superficial cervical fascia and deep cervical fascia.

[0071] like Figure 9As shown, the locking assembly 310 in this embodiment specifically includes: a rotating handle 311 rotatably set on the support frame 300, a rotating shaft 312 and an eccentric wheel 313. A docking hole 301 is provided on the support frame 300, and the inflatable connector 100 can be inserted into the docking hole 301 from bottom to top, and then locked by the locking assembly 310. The rotating shaft 312 is rotatably set in the support frame 300 and its two ends protrude from the outer wall of the support frame 300, and the rotating shaft 312 deviates from the center of the docking hole 301 and is located on the outside of the docking hole 301. The rotating handle 311 is located on the outside of the support frame 300 and is connected to the two ends of the rotating shaft 312. By turning the rotating handle 311, the rotating shaft 312 can be driven to rotate a certain angle. The eccentric wheel 313 is fixedly arranged in the middle position of the rotating shaft 312, so that the rotating rotating shaft 312 can drive the eccentric wheel 313 to rotate. The eccentric wheel 313 can protrude from the docking hole 301 or be accommodated in the support frame 300 during rotation.

[0072] like Figure 8 、 Figure 9 As shown, when the inflatable connector 100 is inserted into the docking hole 301 and the position is adjusted, after the upper and lower positions are adjusted, the superficial cervical fascia is supported by the airbag component 200 at the lower end of the inflatable connector 100 to achieve the ideal surgical space. From top to bottom (or from bottom to top), the rotating handle 311 is turned, and the rotating handle 311 drives the rotating shaft 312 to rotate. The rotating shaft 312 drives the eccentric wheel 313 to rotate and then transfer from the inner wall of the support frame 300 to the docking hole 301, thereby pressing the inflatable connector 100 in the docking hole 301. If the rotating handle 311 is turned in the opposite direction, the eccentric wheel 313 rotates and is accommodated from the docking hole 301 to the inner wall of the support frame 300, thereby loosening the inflatable connector 100. In order to facilitate the compression of the inflatable connector 100, an elastic layer (such as a rubber layer) is usually provided on the surface of the eccentric wheel 313. During the rotation process, a large friction force is generated between the elastic layer and the outer wall of the inflatable connector 100, so that the inflatable connector 100 will not move downward.

[0073] In summary, this application proposes a surgical airbag support structure that replaces the existing method of directly inflating the body with airbag support, eliminating residual gas in the patient's body, thereby enabling faster recovery and improving medical efficiency. Furthermore, the inflation state can be controlled, avoiding the venous area and thus preventing interference with vascular bleeding, thereby facilitating the doctor's analysis and judgment and making the surgical process more convenient.
