Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to a tissue tray assembly used in abdominal surgery. Background Art

[0002] During abdominal surgery, doctors usually need to move some abdominal tissues that block the surgical site in order to obtain a better surgical field of view to facilitate operations on the surgical site.

[0003] For example, the liver suspension in the Chinese patent with application number CN2023217129673 and patent name "A liver suspension" includes a suspension body, which includes a suspension cylinder, a component arranged on the outside of the suspension cylinder and used to pull the suspension cylinder, a turntable rotatably connected to the bottom of the suspension cylinder, an inner groove opened on the outer periphery of the turntable, a hanging ring arranged inside the inner groove through a connecting column, a rotating cylinder sleeved on the hanging ring, and a baffle arranged on the outside of the rotating cylinder and used to suspend the liver. During the operation, the liver is suspended by using the baffle to pull the liver to adjust the position of the liver so as to obtain a clear exposure field.

[0004] Although the liver suspension device mentioned above can more stably support the tissues in the abdominal cavity and broaden the surgical field of view, the inventors found that the current liver suspension device still has some shortcomings during actual use, specifically:

[0005] When the baffle supports the tissue in the abdominal cavity, under the premise that there is no manual adjustment of the position of the baffle, the supported surface of the tissue continues to contact the baffle during the entire process of the baffle supporting the tissue. In this way, when the operation time is long, the supported surface of the tissue is compressed by the baffle for a long time. Taking liver tissue as an example, when the liver tissue is compressed by the baffle for a long time, the blood vessels in the liver are easily compressed. In this way, the compressed part of the liver tissue may suffer from ischemia and hypoxia due to insufficient blood supply. Secondly, since the tissue in the compressed part cannot get enough nutrition and oxygen, long-term compression may cause cyst-like lesions in the liver tissue.

[0006] Therefore, during abdominal surgery, how to reduce the degree of tissue compression when the tissue in the abdominal cavity is supported is an urgent problem that needs to be solved. Summary of the invention

[0007] The purpose of the present invention is to provide a tissue tray assembly for use in abdominal surgery to reduce the degree of tissue compression, in order to address the problem that the tissue in the abdominal cavity is currently compressed for a long time when supported during a long operation.

[0008] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions:

[0012] The support member includes a sleeve and a telescopic rod, wherein the sleeve is arranged on the tray body, the telescopic rod is located in the sleeve, the telescopic rod is connected to an air pipe, and the air pipe is adapted to the telescopic rod. By injecting or exhausting air into the air pipe, the amount of gas in the telescopic rod is changed to extend or shorten the telescopic rod; the movement forms of the telescopic rod corresponding to the first support member and the telescopic rod corresponding to the second support member are independent.

[0013] As a priority technical solution of the present application, in the process of injecting or exhausting air into the trachea to extend or shorten the telescopic rod, the telescopic rod has two states, namely a first state and a second state. When the telescopic rod is in the first state, the telescopic rod is shortened, at this time the telescopic rod is at its minimum length, and the length of the telescopic rod is a; when the telescopic rod is in the second state, the telescopic rod is extended, at this time the telescopic rod is at its maximum length, and the length of the telescopic rod is b; a≤1 / 4b.

[0014] As a preferred technical solution of the present application, the telescopic rod includes a seat body and a sub-rod group, the sub-rod group is arranged on the seat body, the sub-rod group includes a plurality of sub-rods, the plurality of sub-rods are distributed along the length direction of the telescopic rod, adjacent sub-rods are mutually sleeved, the plurality of sub-rods jointly form a main chamber, the air pipe is connected to the seat body, a first channel is formed in the seat body, and the main chamber is connected to the air pipe through the first channel;

[0015] When the telescopic rod is in the first state, gas is injected into the air pipe so that gas is injected into the main chamber, thereby increasing the volume of the main chamber and causing adjacent sub-rods to move relative to each other, thereby extending the telescopic rod;

[0016] When the telescopic rod is in the second state, air is pumped into the air pipe so that the gas in the main chamber is pumped out through the first channel, thereby reducing the volume of the main chamber, causing adjacent sub-rods to move relative to each other, and increasing the overlap between adjacent sub-rods, thereby shortening the telescopic rod.

[0017] As a preferred technical solution of the present application, the sub-rod on the plurality of sub-rods that is away from the seat body is a first sub-rod, and one end of the first sub-rod that is away from the seat body is hemispherical.

[0018] As a preferred technical solution of the present application, the tray body is an elastic annular membrane structure, an inner edge portion and an outer edge portion are formed on the tray body, the inner edge portion is located at the inner edge of the tray body, the outer edge portion is located at the outer edge of the tray body, and the sleeve extends from the inner edge portion to the outer edge portion;

[0019] When the telescopic rod is in the second state, the sleeve is filled with the telescopic rod.

[0020] As a priority technical solution of the present application, the tissue tray assembly also includes a control device, which includes a first control member and a second control member, the first control member is connected to the air tubes corresponding to the several first support members, and the first control member is used to inject or exhaust air into the air tubes corresponding to the several first support members so that the telescopic rods corresponding to the several first support members can be synchronously extended or shortened; the second control member is connected to the air tubes corresponding to the several second support members, and the second control member is used to inject or exhaust air into the air tubes corresponding to the several second support members so that the telescopic rods corresponding to the several second support members can be synchronously extended or shortened.

[0021] As a preferred technical solution of the present application, the tray further includes a first airbag ring and a second airbag ring, wherein the first airbag ring and the second airbag ring are both arranged on the outer edge portion;

[0022] The first airbag ring is connected to the sleeves corresponding to the first support members, and the sleeves corresponding to the first support members and the first airbag ring form a closed first chamber. When the telescopic rods corresponding to the first support members change from a first state to a second state, the sleeves corresponding to the first support members are gradually filled with the telescopic rods, so that the gas in the corresponding sleeves is squeezed into the first airbag ring, so that the first airbag ring is inflated and fixed; when the telescopic rods corresponding to the first support members change from the second state to the first state, the telescopic rods are gradually shortened, so that the gas in the first airbag ring can be gradually diverted to the corresponding sleeves, so that the first airbag ring becomes deflated;

[0023] The second airbag ring is connected to the sleeves corresponding to the plurality of second support members, and the sleeves corresponding to the plurality of second support members and the second airbag ring form a closed second chamber. When the telescopic rods corresponding to the plurality of second support members change from a first state to a second state, the sleeves corresponding to the second support members are gradually filled with the telescopic rods, so that the gas in the corresponding sleeves is squeezed into the second airbag ring, so that the second airbag ring is inflated and shaped. In the process of the telescopic rods corresponding to the plurality of second support members changing from the second state to the first state, the telescopic rods are gradually shortened, so that the gas in the second airbag ring can be gradually diverted to the corresponding sleeves, so that the second airbag ring becomes deflated.

[0024] As a preferred technical solution of the present application, when the tray supports the tissue, the tray has a funnel-shaped structure.

[0025] As a preferred technical solution of the present application, the seat body is fixed on the sleeve body at a position close to the inner edge.

[0026] As a preferred technical solution of the present application, the traction device includes three traction lines, one end of each traction line is connected to the outer edge, and the other end of each traction line is used to be fixed to the inner wall of the abdomen;

[0027] The three traction lines are evenly distributed on the outer edge around the central axis of the tray body.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. In the scheme of the present application, by providing a tray body and a plurality of support members, when the tray supports the tissue, the support members play a major supporting role for the tissue, by providing a first support member and a second support member, and making the movement forms of the telescopic rod corresponding to the first support member and the telescopic rod corresponding to the second support member independent, when the tray supports the tissue, by injecting or exhausting air into the trachea, the telescopic rod corresponding to the first support member is extended, and the telescopic rod corresponding to the second support member is shortened. Thus, in this state, in the process of the tray supporting the tissue, since the telescopic rod corresponding to the first support member is longer at this time, the telescopic rod corresponding to the first support member plays a major supporting role for the tissue compared with the telescopic rod corresponding to the second support member. Then, after adjusting the amount of gas in the telescopic rod corresponding to the first support member and the telescopic rod corresponding to the second support member, the telescopic rod corresponding to the first support member is shortened, and the telescopic rod corresponding to the second support member is extended. Thus, in this state, since the telescopic rod corresponding to the second support member is longer at this time , so that the telescopic rod corresponding to the second support member plays a major supporting role on the tissue compared to the telescopic rod corresponding to the first support member. In this way, by intermittently changing the amount of gas in the telescopic rod corresponding to the first support member and the telescopic rod corresponding to the second support member, the supporting role of the first support member and the second support member on the tissue is adjusted, thereby avoiding the supported area on the tissue from being supported by the first support member or the second support member for a long time, so that when the first support member plays a major supporting role on the tissue, the degree of compression of the area on the tissue corresponding to the second support member can be reduced. Similarly, when the second support member plays a major supporting role on the tissue, the degree of compression of the area on the tissue corresponding to the first support member can be reduced, thereby avoiding the tissue in the abdominal cavity from being in a state of long-term compression, and further avoiding the blood vessels in the tissue from being in a state of long-term compression, thereby avoiding insufficient blood supply, ischemia or hypoxia in the supported part of the tissue, and further avoiding the occurrence of cystic lesions in tissues such as the liver due to long-term compression;

[0030] Furthermore, during the process of extending or shortening the telescopic rod, the extension and retraction of the telescopic rod will drive the tissue movement to massage the tissue, thereby further improving the blood circulation in the supported tissue and further reducing the risk of ischemic injury.

[0031] At the same time, by changing the amount of gas in the telescopic rod, the telescopic rod is shortened, thereby reducing the space occupied by the telescopic rod, and further reducing the space occupied by the tray, thereby facilitating the placement of the tray from outside the body into the abdominal cavity, thereby improving the convenience of arranging the tray in the abdominal cavity;

[0032] 2. Further, by providing a seat body and a sub-rod group, the sub-rod group includes a plurality of sub-rods, and by injecting or exhausting gas into the air pipe, the amount of gas in the main chamber changes, thereby changing the volume of the main chamber, thereby causing adjacent sub-rods to move relatively, thereby controlling the length of the entire sub-rod group, thereby achieving the purpose of adjusting the length of the telescopic rod, thereby improving the convenience of adjusting the length of the telescopic rod, and in the present application, adjacent sub-rods are mutually sleeved, and the parts where the adjacent sub-rods are sleeved are in close contact, which can prevent the gas in the main chamber from escaping from the parts where the adjacent sub-rods are sleeved, thereby improving the stability of the telescopic rod in the second state;

[0033] 3. Further, by setting the first airbag ring and the second airbag ring, taking the first airbag ring as an example, in the process that the sleeve corresponding to the first support member is gradually filled with the telescopic rod, the gas in the corresponding sleeve is gradually squeezed into the first airbag ring until the first airbag ring is inflated and shaped, so that the inflated first airbag ring can maintain a stable annular structure, so that the inflated first airbag ring and the first support member can jointly play a major supporting role on the tissue, which can further improve the supported effect of the tissue. At the same time, the inflated first airbag ring and the first support members can jointly form the skeleton structure of the tray, which can further improve the stability of the tray structure in this form, and further improve the stability of the tray in this form in supporting the tissue;

[0034] At the same time, the first airbag ring that is shaped after inflation and the second airbag ring that is shaped after inflation are distributed on the tray body in a staggered manner, so that the part of the tissue supported by the first airbag ring that is shaped after inflation is different from the part of the tissue supported by the second airbag ring that is shaped after inflation. In this way, the area of ​​the tissue corresponding to the first airbag ring or the second airbag ring that is shaped after inflation can be further reduced from being in a supported state for a long time, and the degree of compression of the tissue is further reduced;

[0035] 4. Further, when the tray supports the tissue, the tray is in a funnel-shaped structure. Thus, when the first airbag ring is inflated and shaped, the inflated and shaped first airbag ring and the first supporting members together form a skeleton structure of the tray. At this time, the tray is in a funnel-shaped structure, which can further reduce the displacement probability of the fabricated tissue, thereby improving the stability of the position of the supported tissue;

[0036] Furthermore, when the telescopic rod corresponding to the first support member and the telescopic rod corresponding to the second support member are both in the first state, at this time, the several telescopic rods on the tray can be in a shortened state, and on the basis of the position close to the inner edge portion of the seat body fixed to the sleeve body, other areas on the tray body except those close to the inner circle can be made to correspond to no support members, and then other areas on the tray body except those close to the inner circle can be made soft, so that the tray can form a flexible net bag-like structure to hold the tissue to be supported. In this way, in the process of arranging the tray in the patient's abdominal cavity, the telescopic rod corresponding to the first support member and the telescopic rod corresponding to the second support member can be both in the first state, so that the tray with a flexible net bag-like structure can hold the tissue to be supported, and then the traction device can be pulled and fixed to the patient's abdomen. The inner wall of the abdomen, during the pulling of the traction device, since the tissue to be supported is held by the tray, it can be prevented from escaping from the tray, and it is convenient to adjust the position of the tissue, so as to further improve the convenience of obtaining a clear exposure field. After the traction device is fixed to the inner wall of the patient's abdomen, the amount of gas in the telescopic rod corresponding to the first support member and the telescopic rod corresponding to the second support member is intermittently changed, so that when the telescopic rod corresponding to the first support member is in the first state, the telescopic rod corresponding to the second support member is in the second state, or when the telescopic rod corresponding to the first support member is in the second state, the telescopic rod corresponding to the second support member is in the first state, so as to adjust the supporting effect of the first support member and the second support member on the tissue, thereby avoiding the supported area on the tissue being supported by the first support member or the second support member for a long time.

[0047] Embodiment 1: This embodiment provides a tissue tray 1 assembly for abdominal surgery, see Figure 1-Figure 4As shown, it includes a tray 1 and a traction device 2, wherein the tray 1 is connected to the traction device 2, and the traction device 2 is used to be fixed to the inner wall of the abdomen so that the tray 1 is fixed relative to the abdomen;

[0048] The tray 1 is used to support tissues. The tray 1 includes a tray body 3 and a plurality of support members 4. The plurality of support members 4 are distributed on the tray body 3 around the central axis of the tray body 3, so that the plurality of support members 4 are distributed on the tray body 3 in a scattered structure.

[0049] The plurality of support members 4 are divided into first support members 5 and second support members 6, and the first support members 5 and the second support members 6 are arranged alternately;

[0050] The support member 4 includes a sleeve 7 and a telescopic rod 8, the sleeve 7 is arranged on the tray body 3, the telescopic rod 8 is located in the sleeve 7, the telescopic rod 8 is connected to an air pipe 9, the air pipe 9 is adapted to the telescopic rod 8, and the amount of gas in the telescopic rod 8 is changed by injecting or exhausting air into the air pipe 9 to make the telescopic rod 8 extend or shorten; the movement form of the telescopic rod 8 corresponding to the first support member 5 and the telescopic rod 8 corresponding to the second support member 6 are independent.

[0051] In the present application, by providing a tray body 3 and a plurality of support members 4, when the tray 1 supports the tissue, the support members 4 play a major supporting role for the tissue, and by providing a first support member 5 and a second support member 6, and making the telescopic rod 8 corresponding to the first support member 5 and the telescopic rod 8 corresponding to the second support member 6 move independently, so that when the tray 1 supports the tissue, by injecting or exhausting air into the trachea 9, the telescopic rod 8 corresponding to the first support member 5 is extended, and the telescopic rod 8 corresponding to the second support member 6 is shortened. Thus, in this state, in the process of the tray 1 supporting the tissue, since the telescopic rod 8 corresponding to the first support member 5 is longer at this time, the telescopic rod 8 corresponding to the first support member 5 plays a major supporting role for the tissue compared to the telescopic rod 8 corresponding to the second support member 6.

[0052] Then, after adjusting the amount of gas in the telescopic rod 8 corresponding to the first support member 5 and the telescopic rod 8 corresponding to the second support member 6, the telescopic rod 8 corresponding to the first support member 5 is shortened, and the telescopic rod 8 corresponding to the second support member 6 is extended. In this state, since the telescopic rod 8 corresponding to the second support member 6 is longer at this time, the telescopic rod 8 corresponding to the second support member 6 plays a major supporting role for the tissue compared to the telescopic rod 8 corresponding to the first support member 5. In this way, the amount of gas in the telescopic rod 8 corresponding to the first support member 5 and the telescopic rod 8 corresponding to the second support member 6 is intermittently changed to adjust the supporting role of the first support member 5 and the second support member 6 on the tissue , thereby preventing the supported area on the tissue from being supported by the first support member 5 or the second support member 6 for a long time, so that when the first support member 5 plays its main supporting role on the tissue, the degree of compression of the area on the tissue corresponding to the second support member 6 can be reduced. Similarly, when the second support member 6 plays its main supporting role on the tissue, the degree of compression of the area on the tissue corresponding to the first support member 5 can be reduced, thereby preventing the tissue in the abdominal cavity from being in a state of long-term compression, and further preventing the blood vessels in the tissue from being in a state of long-term compression, thereby preventing the supported parts of the tissue from having insufficient blood supply, ischemia or hypoxia, and further preventing tissues such as the liver from having cystic lesions due to long-term compression;

[0053] Furthermore, during the process of extending or shortening the telescopic rod 8, the extension and retraction of the telescopic rod 8 will drive the tissue to move, so as to massage the tissue, thereby further improving the blood circulation in the supported tissue and further reducing the risk of ischemic injury.

[0054] At the same time, by changing the amount of gas in the telescopic rod 8, the telescopic rod 8 is shortened, thereby reducing the space occupied by the telescopic rod 8, and then the space occupied by the tray 1 can be reduced, thereby facilitating the placement of the tray 1 from outside the body into the abdominal cavity, thereby improving the convenience of arranging the tray 1 in the abdominal cavity.

[0055] As a preferred embodiment, on the basis of the above-mentioned manner, further, in the process of injecting or exhausting air into the air pipe 9 to extend or shorten the telescopic rod 8, the telescopic rod 8 has two states, namely a first state and a second state. When the telescopic rod 8 is in the first state, the telescopic rod 8 is shortened, at this time the telescopic rod 8 is at the minimum length, and the length of the telescopic rod 8 is a; when the telescopic rod 8 is in the second state, the telescopic rod 8 is extended, at this time the telescopic rod 8 is at the maximum length, and the length of the telescopic rod 8 is b; a≤1 / 4b.

[0056] Furthermore, by injecting or exhausting air into the trachea 9, the telescopic rod 8 is extended or shortened, so that the telescopic rod 8 is in the first state or the second state, and the length a of the telescopic rod 8 when it is in the minimum length is less than or equal to 1 / 4 of the length b when the telescopic rod 8 is in the maximum length. In this way, when the telescopic rod 8 corresponding to the first support member 5 is in the first state and the telescopic rod 8 corresponding to the second support member 6 is in the second state, the telescopic rod 8 corresponding to the first support member 5 can occupy a smaller space, thereby further improving the supporting effect of the telescopic rod 8 in the second state on the tissue, and reducing the degree of compression of the area on the tissue corresponding to the telescopic rod 8 in the first state, thereby further avoiding the tissue in the abdominal cavity from being compressed for a long time.

[0057] As a preferred embodiment, on the basis of the above-mentioned manner, further, the telescopic rod 8 includes a seat body 10 and a sub-rod group 11, the sub-rod group 11 is arranged on the seat body 10, the sub-rod group 11 includes a plurality of sub-rods 12, the plurality of sub-rods 12 are distributed along the length direction of the telescopic rod 8, adjacent sub-rods 12 are mutually sleeved, and the plurality of sub-rods 12 jointly form a main chamber 13, the air pipe 9 is connected to the seat body 10, a first channel 14 is formed in the seat body 10, and the main chamber 13 is communicated with the air pipe 9 through the first channel 14;

[0058] When the telescopic rod 8 is in the first state, gas is injected into the air pipe 9 so that the gas is injected into the main chamber 13, so that the volume of the main chamber 13 increases, and the adjacent sub-rods 12 move relatively, so that the telescopic rod 8 is extended;

[0059] When the telescopic rod 8 is in the second state, air is pumped into the air pipe 9 so that the gas in the main chamber 13 is pumped out through the first channel 14, thereby reducing the volume of the main chamber 13, causing adjacent sub-rods 12 to move relative to each other, and increasing the overlap between adjacent sub-rods 12, thereby shortening the telescopic rod 8.

[0060] Furthermore, by setting a seat body 10 and a sub-rod group 11, the sub-rod group 11 includes a plurality of sub-rods 12. By injecting or exhausting air into the air pipe 9, the amount of gas in the main chamber 13 is changed, thereby changing the volume of the main chamber 13, so that adjacent sub-rods 12 are moved relative to each other, thereby controlling the length of the entire sub-rod group 11, so as to achieve the purpose of adjusting the length of the telescopic rod 8, thereby improving the convenience of adjusting the length of the telescopic rod 8. In the present application, adjacent sub-rods 12 are nested with each other, and the parts where the adjacent sub-rods 12 are nested are in contact with each other, which can prevent the gas in the main chamber 13 from escaping from the parts where the adjacent sub-rods 12 are nested, thereby improving the stability of the telescopic rod 8 when it is in the second state.

[0061] As a preferred embodiment, on the basis of the above-mentioned manner, further, the sub-rod 12 on the plurality of sub-rods 12 away from the seat body 10 is a first sub-rod 15, and one end of the first sub-rod 15 away from the seat body 10 is hemispherical.

[0062] Furthermore, the end of the first sub-rod 15 away from the seat body 10 is hemispherical, so that the tray 1 supports the tissue and can improve the smoothness of the movement of the telescopic rod 8 during the extension of the telescopic rod 8, thereby improving the smoothness of switching the state of the telescopic rod 8.

[0063] Embodiment 2: Based on the technical solution of embodiment 1, further, see Figure 1-Figure 4 As shown, the tray body 3 is an elastic annular membrane structure, and an inner edge portion 16 and an outer edge portion 17 are formed on the tray body 3. The inner edge portion 16 is located at the inner edge of the tray body 3, and the outer edge portion 17 is located at the outer edge of the tray body 3. The sleeve 7 extends from the inner edge portion 16 to the outer edge portion 17;

[0064] When the telescopic rod 8 is in the second state, the sleeve 7 is filled with the telescopic rod 8 .

[0065] Furthermore, the sleeve 7 is extended from the inner edge 16 to the outer edge 17, and when the telescopic rod 8 is in the second state, the sleeve 7 is filled with the telescopic rod 8, so that one end of the telescopic rod 8 is located at one end inside the sleeve 7, and the other end of the telescopic rod 8 is located at the other end inside the sleeve 7. When the telescopic rod 8 is in the second state, one end of the telescopic rod 8 in the second state is close to the outer edge 17, and the other end is close to the inner edge 16. In this way, when the tray 1 supports the tissue, the supporting effect of the telescopic rod 8 in the second state on the tissue can be further enhanced.

[0066] As a preferred embodiment, on the basis of the above-mentioned method, further, the tissue tray 1 assembly also includes a control device 18, and the control device 18 includes a first control component 19 and a second control component 20. The first control component 19 is connected to the air tubes 9 corresponding to the several first support members 5, and the first control component 19 is used to inject or exhaust air into the air tubes 9 corresponding to the several first support members 5, so that the telescopic rods 8 corresponding to the several first support members 5 are synchronously extended or shortened; the second control component 20 is connected to the air tubes 9 corresponding to the several second support members 6, and the second control component 20 is used to inject or exhaust air into the air tubes 9 corresponding to the several second support members 6, so that the telescopic rods 8 corresponding to the several second support members 6 are synchronously extended or shortened.

[0067] Furthermore, by setting the first control member 19 and the second control member 20, the first control member 19 is connected to the air pipes 9 corresponding to the plurality of first support members 5, and the second control member 20 is connected to the air pipes 9 corresponding to the plurality of second support members 6. The first control member 19 includes a first main air pipe 21 and a first pumping device 22. One end of the first main air pipe 21 is connected to the first pumping device 22, and the other end of the first main air pipe 21 is connected to the air pipes 9 corresponding to the plurality of first support members 5. The first pumping device 22 is similar to a syringe structure. By pushing and pulling the piston rod on the first pumping device 22, the piston rod on the first pumping device 22 is relative to the cylinder on the first pumping device 22.

[0069] Embodiment 3: Based on the technical solution of Embodiment 2, further, see Figure 1 , Figure 3 and Figure 4 As shown, the tray 1 further includes a first airbag ring 25 and a second airbag ring 26, and the first airbag ring 25 and the second airbag ring 26 are both arranged on the outer edge portion 17;

[0070] The first airbag ring 25 is connected to the sleeves 7 corresponding to the first support members 5, and the sleeves 7 corresponding to the first support members 5 and the first airbag ring 25 form a closed first chamber. When the telescopic rods 8 corresponding to the first support members 5 change from the first state to the second state, the sleeves 7 corresponding to the first support members 5 are gradually filled with the telescopic rods 8, so that the gas in the corresponding sleeves 7 is squeezed into the first airbag ring 25, so that the first airbag ring 25 is inflated and fixed; in the process of the telescopic rods 8 corresponding to the first support members 5 changing from the second state to the first state, the telescopic rods 8 are gradually shortened, so that the gas in the first airbag ring 25 can be gradually diverted to the corresponding sleeves 7, so that the first airbag ring 25 becomes deflated;

[0071] The second airbag ring 26 is connected to the sleeves 7 corresponding to the plurality of second support members 6, and the sleeves 7 corresponding to the plurality of second support members 6 and the second airbag ring 26 form a closed second chamber. When the telescopic rods 8 corresponding to the plurality of second support members 6 change from a first state to a second state, the sleeves 7 corresponding to the second support members 6 are gradually filled with the telescopic rods 8, so that the gas in the corresponding sleeves 7 is squeezed into the second airbag ring 26, so that the second airbag ring 26 is inflated and shaped; in the process of the telescopic rods 8 corresponding to the plurality of second support members 6 changing from the second state to the first state, the telescopic rods 8 are gradually shortened, so that the gas in the second airbag ring 26 can be gradually diverted to the corresponding sleeves 7, so that the second airbag ring 26 becomes deflated.

[0072] Furthermore, by providing a first airbag ring 25 and a second airbag ring 26, taking the first airbag ring 25 as an example, in the process that the sleeve 7 corresponding to the first support member 5 is gradually filled with the telescopic rod 8, the gas in the corresponding sleeve 7 is gradually squeezed into the first airbag ring 25 until the first airbag ring 25 is inflated and shaped, so that the inflated first airbag ring 25 can maintain a stable annular structure, so that the inflated first airbag ring 25 and the first support member 5 after inflation and shaping jointly play a major supporting role on the tissue, which can further improve the supported effect of the tissue, and at the same time, the inflated first airbag ring 25 and several first support members 5 jointly form the skeleton structure of the tray 1, which can further improve the stability of the tray 1 structure in this form, and further improve the stability of the tray 1 in this form in supporting the tissue;

[0073] At the same time, the first airbag ring 25 that is shaped after inflation and the second airbag ring 26 that is shaped after inflation are distributed in a staggered manner on the tray body 3, so that the part of the tissue supported by the first airbag ring 25 that is shaped after inflation and the part of the tissue supported by the second airbag ring 26 that is shaped after inflation are different. In this way, the area on the tissue corresponding to the first airbag ring 25 or the second airbag ring 26 is further reduced in a supported state for a long time, further reducing the degree of compression of the tissue.

[0074] As a preferred embodiment, on the basis of the above-mentioned manner, further, when the tray 1 supports the tissue, the tray 1 has a funnel-shaped structure.

[0075] As a preferred embodiment, on the basis of the above-mentioned manner, further, the seat body 10 is fixed on the sleeve body 7 at a position close to the inner edge portion 16 .

[0076] Furthermore, when the tray 1 supports the tissue, the tray 1 is in a funnel-shaped structure. Thus, when the first airbag ring 25 is inflated and shaped, the inflated and shaped first airbag ring 25 and the first supporting members 5 together form the skeleton structure of the tray 1. At this time, the tray 1 is in a funnel-shaped structure, which can further reduce the displacement probability of the fabricated tissue, thereby improving the stability of the position of the supported tissue.

[0077] Furthermore, when the telescopic rod 8 corresponding to the first support member 5 and the telescopic rod 8 corresponding to the second support member 6 are both in the first state, at this time, the several telescopic rods 8 on the tray 1 can be in a shortened state, and on the basis of the position of the seat body 10 fixed to the sleeve body 7 near the inner edge 16, the other areas on the tray body 3 except those near the inner circle can be made to not correspond to the support member 4, and then the other areas on the tray body 3 except those near the inner circle can be made soft, so that the tray 1 can form a flexible net bag-like structure to hold the tissue to be supported. In this way, in the process of arranging the tray 1 in the patient's abdominal cavity, the telescopic rod 8 corresponding to the first support member 5 and the telescopic rod 8 corresponding to the second support member 6 can be both in the first state, so that the tray 1 with a flexible net bag-like structure can hold the tissue to be supported, and then the traction device 2 can be pulled and fixed on the patient. The inner wall of the abdomen of the patient. During the pulling process of the traction device 2, since the tissue to be supported is held by the tray 1, it can be prevented from falling out of the tray 1, and it is convenient to adjust the position of the tissue, so as to further improve the convenience of obtaining a clear exposure field. After the traction device 2 is fixed to the inner wall of the abdomen of the patient, the amount of gas in the telescopic rod 8 corresponding to the first support member 5 and the telescopic rod 8 corresponding to the second support member 6 is intermittently changed, so that when the telescopic rod 8 corresponding to the first support member 5 is in the first state, the telescopic rod 8 corresponding to the second support member 6 is in the second state, or when the telescopic rod 8 corresponding to the first support member 5 is in the second state, the telescopic rod 8 corresponding to the second support member 6 is in the first state, so as to adjust the supporting effect of the first support member 5 and the second support member 6 on the tissue, thereby avoiding the supported area on the tissue being supported by the first support member 5 or the second support member 6 for a long time.

[0078] As a preferred embodiment, based on the above-mentioned manner, further, the traction device 2 includes three traction wires 27, one end of the traction wire 27 is connected to the outer edge portion 17, and the other end of the traction wire 27 is used to be fixed to the inner wall of the abdomen;

[0079] The three pulling lines 27 are evenly distributed on the outer edge portion 17 around the central axis of the tray body 3 .

[0080] Furthermore, by setting three traction lines 27, one end of the traction line 27 is connected to the outer edge portion 17, and the other end of the traction line 27 is used to be fixed to the inner wall of the abdomen, so as to improve the convenience of fixing the traction device 2 to the inner wall of the abdomen, so as to fix the tray 1 relative to the abdomen, wherein the specific method of fixing the traction line 27 to the inner wall of the abdomen is the existing technology, so it will not be repeated here.
