Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a supporting device for laparoscopic surgery. Background Art

[0002] Traditional laparoscopic surgery usually requires the introduction of carbon dioxide into the abdominal cavity to separate the abdominal wall and intracavitary organs, forming a carbon dioxide pneumoperitoneum space that is convenient for manual operation, and performing surgery under the pneumoperitoneum state. However, since carbon dioxide can be absorbed through the peritoneum, excessive carbon dioxide can easily cause hypercapnia and acidosis. Especially for elderly patients, abnormal changes in heart rate and breathing are likely to occur after establishing artificial carbon dioxide pneumoperitoneum for laparoscopic surgery. In addition, during the pneumoperitoneum process, the patient's lower limb venous return is significantly reduced, the central venous pressure is increased, and the distal veins are dilated. For the elderly, affected by carbon dioxide, their body temperature drops and their blood flow slows down, making it easier to induce thrombosis during surgery, causing a series of complications, increasing the risk of surgery, and causing physical pain and life-threatening danger to patients. Therefore, for some patients, only pneumoperitoneum-free laparoscopic surgery can be performed.

[0003] In pneumoperitoneum-free laparoscopic surgery, a special abdominal wall suspension device is required to separate the abdominal wall and internal organs. Traditional pneumoperitoneum-free laparoscopic surgery generally involves inserting a long needle into the abdominal cavity, or an expandable and contractible fan-shaped structure that fits against the abdominal wall, and pulling the long needle or fan-shaped structure through the suspension device to form a surgical space between the abdominal wall and the organs in the cavity. However, since the long needle or fan-shaped structure has a sharp puncture site, it is easy to puncture or scratch the internal organs during the process of insertion into the abdominal cavity and in the process of separating the abdominal wall and internal organs, resulting in internal bleeding when separating the abdominal wall and internal organs, which increases pain and surgical risks for patients and affects the smooth progress of the operation.

[0004] The patent document with publication number CN108670324A discloses an airbag support device for laparoscopic surgery, including a hollow rod-shaped support rod, a bottom cover is provided at the bottom of the support rod, a top cover is provided at the top, a slider is provided in the support rod, and a accommodating chamber is formed between the slider and the bottom cover, an airbag is provided in the accommodating chamber, the slider is connected to the top of the airbag, and at least two openings are provided on the side wall of the accommodating chamber; when in use, the slider is slid toward the bottom of the support rod, the airbag extends from the opening to the outside of the support rod, and then the support rod is lifted to drive the airbag to move upward, the airbag separates the abdominal wall and the organs in the cavity, forming a surgical field of view, which is convenient for doctors to perform surgery.

[0005] However, the following problems still exist in the process of lifting the abdominal wall and creating a surgical field of view using this support device:

[0006] (1) When the support device cooperates with the support frame to separate the abdominal wall and the intracavitary organs to form a surgical field of view, the lower part of the support device is inserted into the abdominal cavity through an abdominal incision. When separating the abdominal cavity, it also exerts a continuous upward pulling force on the incision, which can easily lead to incision tearing over a long period of time. In addition, the postoperative traction injury of the abdominal wall causes the patient to feel obvious pain and takes a long time to heal.

[0007] (2) When the support device vertically lifts the abdominal wall to create a surgical field of view, the actual surgical field of view is not ideal because the vertical lifting means that the organs in the abdominal cavity will be driven toward the center.

[0008] (3) The support device is recyclable and needs to be stored and strictly disinfected after each use before it can be used again. Therefore, the subsequent maintenance cost is relatively high.

[0009] Therefore, it is urgent to design a supporting device for laparoscopic surgery to solve the above problems. Summary of the invention

[0010] In view of the problems that during the use of the above-mentioned existing laparoscopic surgery support device, the long-term pulling force on the incision and the pulling injury to the abdominal wall cause the patient to feel obvious pain, the healing time is long, and the surgical field of view created by lifting the abdominal wall is not ideal, the purpose of the utility model is to provide a support device for laparoscopic surgery, including a bottom membrane, and an air column group is arranged on the outer surface of the bottom membrane. The air column group can be inflated so that the device can be enlarged from small to large, thereby separating the abdominal wall and the organs in the cavity, forming a surgical space that is convenient for manual operation; further, the bottom membrane is a fan-shaped structure, and after being inflated, its two ends are openings of different sizes, so that the doctor can choose to insert the surgical instrument from any opening according to the needs of the operation;

[0011] Furthermore, a positioning piece is provided on the lower side of any inflatable column, and the positioning piece positions the support device at a target position. When the inflated support device expands at a fixed position, a larger surgical space is created at the fixed position.

[0012] The core technical idea of ​​this utility model is:

[0013] The setting of the airbag structure is better than using carbon dioxide and a pulling structure to separate the abdominal wall and the organs in the cavity, and makes up for the defects of using carbon dioxide and a pulling structure. It has a simple structure, is easy to use, and has a wide range of materials to choose from, such as silicone, polyethylene, polypropylene, polyvinyl chloride, etc. Therefore, it has a low production cost, is easy to store and is disposable, which means it is hygienic and will not cause economic pressure.

[0014] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0015] A support device for laparoscopic surgery, characterized in that it comprises a base membrane, an air column group is arranged on the outer side of the base membrane, the air column group is connected to a ventilation tube, and the ventilation tube is arranged on the outer side of the base membrane.

[0016] Preferably, the base film is a fan-shaped structure.

[0017] Preferably, the air column group includes a plurality of air-filled columns, and the plurality of air-filled columns are arranged at equal intervals on the outer side of the base film.

[0018] Preferably, a plurality of positioning members are provided on the lower side of any inflatable column.

[0019] Preferably, the positioning member includes a plurality of positioning balls, and the positioning balls are wrapped with a soft outer layer.

[0020] Preferably, the bottom film is a double-layer structure and is connected to an air delivery pipe. The bottom film is folded to form a plurality of inverted V-shaped structures, the inverted V-shaped structures are adapted to the air column group, and the ventilation pipe is an elastic tube.

[0021] Preferably, in the inverted V-shaped structure, the overlapping portion of the inner film and the outer film of the base film is provided with a sticking point, and the adhesive force of the sticking point is smaller than the pulling force generated by the inner film and the outer film after the base film expands.

[0022] The beneficial effects of the utility model are as follows: the utility model discloses a support device for laparoscopic surgery. Compared with the prior art, the improvements of the utility model are:

[0023] (1) The utility model designs a bottom membrane, which can be a single-layer structure or a double-layer structure. When it is a single-layer structure, its diameter will not increase and is a fixed specification; when it is a double-layer structure, it is folded into an inverted V-shaped structure, and the inverted V-shaped structure and the air column group are staggered. By ventilating the bottom membrane, the inverted V-shaped structure can be automatically unfolded, thereby increasing the diameter of the bottom membrane, thereby creating a larger surgical space to meet the doctor's surgical needs.

[0024] (2) The utility model provides an air column group on the base membrane, and the air column group is connected to the ventilation tube. The air column group is inflated through the ventilation tube. Under the action of the ventilation tube and the air column group, the base membrane becomes larger and expands into a fan-shaped structure, thereby separating the abdominal wall and the organs in the cavity, forming a surgical space that is convenient for manual operation.

[0025] (3) The utility model is designed with a positioning member, which is arranged on any one of the inflatable columns and is used to position the support device at the target position. The inflatable columns and the base membrane are then inflated so that the inflated support device expands at the fixed position, thereby creating a larger surgical space at the fixed position.

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0033] Embodiment 1:

[0034] See attached Figure 1-5 As shown, a support device for laparoscopic surgery includes a bottom membrane 1. The bottom membrane 1 is made of materials such as silicone, polyethylene, polypropylene, and polyvinyl chloride, and is thin and can be compressed into a very small volume. Preferably, the bottom membrane 1 is a fan-shaped structure. When the two ends of the bottom membrane 1 are spliced ​​together, a structure with a small front and a large back is formed, so as to avoid that after the expansion of the structure with the same size at the front and back (such as a column), a larger space is formed, which provides a larger support area for the patient's abdominal wall, resulting in a large stretch injury site of the abdominal wall after surgery and a long healing time. At the same time, during the operation, the instrument can select different entrances formed by the enlargement of the bottom membrane 1 according to the needs of the operation to enter the surgical space, and a 5mm or 10mm trocar can be inserted into the space formed by the bottom membrane 1 for auxiliary operation.

[0035] An air column group 2 is arranged on the outer side of the bottom film 1. The material of the air column group 2 is the same as that of the bottom film 1. The air column group 2 is connected to a ventilation pipe 3. The ventilation pipe 3 is arranged on the outer side of the bottom film 1. The ventilation pipe 3 is connected to an air inlet pipe 5. The air inlet pipe 5 is externally connected to an inflation device 1. Specifically, the air column group 2 includes a plurality of inflation columns 201, and the plurality of inflation columns 201 are arranged at equal intervals on the outer side of the bottom film 1.

[0036] The inflation device 1 can input gas of fixed pressure into the air inlet pipe 5, and the gas enters the air column group 2 through the air inlet pipe 5 and the ventilation pipe 3, and finally makes the support device of this embodiment expand and thus creates the required surgical space.

[0037] The use method and principle of the support device for laparoscopic surgery of this embodiment are as follows: the air inlet pipe 5 is connected to the ventilating pipe 3, and then the other end of the air inlet pipe 5 is connected with an inflation device 1, and then the support device is placed at the target position in the patient's abdominal cavity through the abdominal incision or the navel, and then the inflation device 1 is turned on, and the inflation device 1 inflates the air column group 2 through the air inlet pipe 5 and the ventilating pipe 3, and the air column group 2 and the ventilating pipe 3 are inflated and expanded, and finally a support device as shown in FIG. Figure 1 The support device shown separates the abdominal wall and the organs in the cavity to form a surgical space that is convenient for manual operation. Instruments can enter the surgical space from the entrances at the front and rear ends of the expanded support device to perform related operations.

[0038] Embodiment 2:

[0039] See attached Figure 1 As shown, the difference between Example 2 and Example 1 is that, based on Example 1, it is found through actual clinical use that when the support device in Example 1 is placed in the abdominal cavity, it is not easy to place due to its light weight, and its position is easy to change during the inflation and expansion process. In order to overcome this problem, in this embodiment, a plurality of positioning members 4 are provided on any one of the inflation columns 201. The positioning member 4 has a certain mass. Preferably, it is a spherical structure, and the outer surface of the spherical structure is wrapped with a soft outer layer. The soft outer layer is made of silicone, and will not cause damage to the tissue when it contacts the patient's abdominal cavity tissue.

[0040] When in use, the positioning member 4 is placed at the target position and in contact with the patient's abdominal tissue, and then the supporting device is inflated to expand it. During this process, the supporting device is easy to place and its position remains unchanged after expansion.

[0041] Embodiment 3:

[0042] See attached Figure 4-5 As shown, the difference between Example 3 and Example 2 is that, based on Example 2, a larger surgical space is required for different surgeries (such as complex liver, gallbladder, pancreas and spleen surgeries) and patients of different body shapes;

[0043] Therefore, in this embodiment, in order to solve the above problems, the bottom film 1 is set to a double-layer structure, and is connected to an air delivery pipe 102, and the air delivery pipe 102 is externally connected to the second inflatable device, wherein the bottom film 1 is folded to have a plurality of inverted V-shaped structures 101, and the inverted V-shaped structures 101 are adapted to the air column group 2, that is, the height of the inverted V-shaped structure 101 is lower than the height of the air column group 2, and the inverted V-shaped structure 101 and the inflatable column 201 are arranged alternately; the ventilation pipe 3 is an elastic pipe, and when the length of the bottom film 1 becomes longer, the ventilation pipe 3 will also be stretched;

[0044] Furthermore, in the inverted V-shaped structure 101, the overlapping part of the inner film and the outer film of the base film 1 is provided with a sticking point 101-1, and the sticking point 101-1 sticks the inner film and the outer film of the base film 1 together, but the adhesion of the sticking point 101-1 is less than the tension generated by the expansion of the inner and outer films of the base film 1, that is, when the base film 1 is inflated through the air pipe 102, the base film 1 further expands, and its inner and outer films are separated, thereby tearing apart the sticking point 101-1 of the inner and outer films, so that the inner and outer films at the sticking point 101-1 are separated, thereby straightening the inverted V-shaped structure 101, increasing the length of the base film 1, and then increasing the expansion space of the base film 1.

[0045] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
