Description

Technical Field

[0001] The utility model relates to surgical tools, in particular to an intestinal tube storage device used in surgical operations. Background Art

[0002] In abdominal surgery, it is usually necessary to control the free intestine to clear the surgical space. Minimally invasive surgery is different from open surgery in that the incision on the human body is smaller, and it is difficult to put larger surgical instruments into the human body. In existing minimally invasive surgery, intestinal grasping forceps or fan-shaped baffles can be used to temporarily clamp or block a section of the small intestine, but the intestine cannot be fixed regionally for a long time. When using a metal fan-shaped baffle, the intestine is pushed to one side for control, but the fan-shaped baffle still has the following disadvantages: First, the surface of the intestine is smooth, and it is easy to slip out of the fan blade gap and the surrounding area of ​​the baffle after peristalsis, and the intestine cannot be controlled in a specific area of ​​the abdominal cavity. Second, the fan-shaped baffle needs to occupy a punch hole to enter the abdominal cavity, and personnel need to continuously hold and operate it. Third, the fan-shaped baffle is made of metal as a whole, which is hard and easy to damage the mesentery, causing damage to the intestinal serosa or hematoma. Utility Model Content

[0031] The utility model provides an intestinal tube storage device for surgical operations, which is mainly used for gathering and storing free intestinal tubes in minimally invasive surgery, so as to facilitate the exposure of deep surgical sites in minimally invasive surgery. The intestinal tube storage device of the utility model can be used to complete complex hepatobiliary and pancreatic surgical operations under minimally invasive conditions, such as liver transplantation, pancreaticoduodenectomy, deep vascular anastomosis reconstruction, etc., to improve surgical efficiency and safety.

[0032] See also Figure 1 The intestinal tube storage device of the utility model comprises a main body 1, a first wing 2, a second wing 3 and a third wing 4, wherein the first wing 2 is fixed in front of the main body 1, the second wing 3 and the third wing 4 are respectively fixed on both sides of the main body 1, and the first wing 2, the second wing 3 and the third wing 4 are sequentially connected and arranged around the main body 1, thereby forming a storage space 5 with the main body 1 for storing the intestinal tube 9 (see Figure 2 ).

[0033] Specifically, the top edge of the first wing 2 is connected to the main body 1, and the two side edges are respectively connected to the second wing 3 and the third wing 4, the second wing 3 and the third wing 4 are symmetrically arranged, the top edge of the second wing 3 is connected to the main body 1, and its front edge is connected to the first wing 2, the top edge of the third wing 4 is connected to the main body 1, and its front edge is connected to the first wing 2.

[0034] In this embodiment, refer to Figure 3 The shape and size of the intestinal tube storage device are set as follows:

[0035] The main body 1 is roughly rectangular or trapezoidal in shape, with a length L0, 8cm≤L0≤10cm, and a width W0, 6cm≤W0≤8cm. When the trapezoidal shape is adopted, the length L0 of the main body 1 increases uniformly from the end close to the first wing 2 to the end away from the first wing 2, that is, the end close to the first wing 2 is narrower.

[0036] The first wing portion 2 is substantially rectangular, with a width W1, 2cm≤W1≤3cm, and a length equivalent to the length of the connection between the main body portion 1 and the first wing portion 2.

[0037] The second wing 3 is roughly triangular in shape, with a width W2, 0cm≤W2≤3cm, and a length equivalent to the length of the connection between the main body 1 and the second wing 3. The width W2 of the second wing 3 decreases uniformly from the end close to the first wing 2 to the end away from the first wing 2.

[0038] The third wing 4 is roughly triangular in shape, with a width W3, 0cm≤W3≤3cm, and a length equivalent to the length of the connection between the main body 1 and the third wing 4. The width W3 of the third wing 4 decreases uniformly from the end close to the first wing 2 to the end away from the first wing 2.

[0039] The width of the second wing 3 and the third wing 4 decreases from one end close to the first wing 2 to the end away from the first wing 2, so that the main body 1 presents a slope from high to low from one end of the first wing 2 to the end away from the first wing 2, which can better gather the intestinal tract at one end of the first wing 2 and prevent the intestinal tract that cannot be gathered from overflowing to the surgical area in front of the first wing 2.

[0040] The main body 1, the first wing 2, the second wing 3 and the third wing 4 are made of flexible sheet materials, so that the intestinal tube storage device can be folded, so that it can be put in and out through the surgical incision. The use of flexible materials also allows the storage space 5 to adaptively change its shape according to the shape of the intestinal tube to better store the intestinal tube. There are many ways to fold, as long as the size after folding can be put in and out through the surgical incision. For example, the intestinal tube storage device forms a columnar structure after folding, and the maximum width of the cross section of the columnar shape is D (see Figure 6 ), preferably D≤6cm, further preferably D≤4cm.

[0041] When used during surgery, the intestinal tube storage device is first folded and then inserted into the human body through the surgical incision. The intestinal tube storage device is unfolded to the use form in the abdominal cavity so that the storage space 5 faces downward and the intestinal tube storage device can cover the intestinal tube 9. The intestinal tube storage device can be moved so that the intestinal tube 9 is gathered and stored in the storage space 5. The first wing 2, the second wing 3 and the third wing 4 can prevent the intestinal tube 9 from sliding out of the storage space 5, and play a gathering role. The intestinal tube storage device is gently pressed downward, and the intestinal tube 9 is gathered in the storage space 5, which can free up surgical space in front of, on both sides and above the intestinal tube 9 storage device.

[0042] In some embodiments, see Figure 4 The intestinal tube storage device also includes a first reinforcement structure 6, a second reinforcement structure 7 and a third reinforcement structure 8.

[0043] A first reinforcing structure 6 is fixed to the bottom edge of the first wing 2, a second reinforcing structure 7 is fixed to the bottom edge of the second wing 3, and a third reinforcing structure 8 is fixed to the bottom edge of the third wing 4. The first reinforcing structure 6, the second reinforcing structure 7 and the third reinforcing structure 8 are long strip-shaped hard structures, which are used to strengthen the strength of the storage space 5, so that after the intestinal tube storage device is unfolded, the storage space 5 can better maintain its unfolded state, thereby having a better gathering and storage effect on the intestinal tube 9, and better preventing the intestinal tube 9 from slipping out from the bottom edges of the first wing 2, the second wing 3 and the third wing 4.

[0044] The first reinforcing structure 6, the second reinforcing structure 7 and the third reinforcing structure 8 can be made of metal materials or other hard materials. The first reinforcing structure 6, the second reinforcing structure 7 and the third reinforcing structure 8 can be wrapped with flexible materials, or hollow wrapping parts can be respectively provided at the bottom edges of the first wing 2, the second wing 3 and the third wing 4, and the first reinforcing structure 6, the second reinforcing structure 7 and the third reinforcing structure 8 are respectively inserted into the wrapping parts of the first wing 2, the second wing 3 and the third wing 4, thereby further reducing the damage to the mesentery.

[0045] In some embodiments, the first reinforcing structure 6 can be configured to be elastic, that is, it can be bent under a certain external force, so that the intestinal tube near one end of the first wing portion 2 in the storage space 5 can bulge outward, reduce the pressure in the storage space 5, and avoid intestinal ischemia and necrosis. The first reinforcing structure 6 can be made of a material with high flexibility, or the thickness of the first reinforcing structure 6 can be made thin, or the whole structure can be made thin, so that it is easy to bend. There are many ways to achieve this, as long as the first reinforcing structure 6 can be bent. The second reinforcing structure and the third reinforcing structure can be configured to be elastic, and the function is similar to the above, or they can be configured to be inelastic or have low elasticity, so that the strength of the storage space 5 can be improved.

[0046] The first reinforcing structure 6 , the second reinforcing structure 7 and the third reinforcing structure 8 can be folded onto the same axis with each other, and the main body 1 , the first wing 2 , the second wing 3 and the third wing 4 can then be folded around the axis.

[0047] There are many ways to fold. In one fold, refer to Figure 5 -6, the second reinforcement structure 7 and the third reinforcement structure 8 can be folded onto the axis of the first reinforcement structure 6, so that the first reinforcement structure 6, the second reinforcement structure 7 and the third reinforcement structure 8 overlap each other, and then the main body 1, the first wing 2, the second wing 3 and the third wing 4 are rolled up around the axis of the first reinforcement structure 6, so that the intestinal tube 9 storage device becomes a columnar structure roughly surrounding the first reinforcement structure 6. The connection between the first reinforcement structure 6 and the second reinforcement structure 7, and the connection between the first reinforcement structure 6 and the third reinforcement structure 8 may not be directly connected, or may be made into a structure that is easy to bend, as long as folding can be achieved.

[0048] In another fold, see Figure 7 , the first reinforcing structure 6 can be folded from the middle, and the second reinforcing structure 7 and the third reinforcing structure 8 can be moved roughly parallel and close to the folded first reinforcing structure 6. Finally, the first reinforcing structure 6, the second reinforcing structure 7 and the third reinforcing structure 8 are roughly overlapped on an axis that is roughly parallel to the second reinforcing structure 7 and the third reinforcing structure 8 and passes through the center point of the intestinal tube 9 storage device. Then the main body 1, the first wing 2, the second wing 3 and the third wing 4 are rolled up around the axis, so that the intestinal tube 9 storage device becomes a columnar structure roughly around the axis. The connection between the first reinforcing structure 6 and the second reinforcing structure 7, and the connection between the first reinforcing structure 6 and the third reinforcing structure 8 may not be directly connected, or may be made into a structure that is easy to bend, as long as folding can be achieved. The first reinforcing structure 6 can be divided into two parts by its middle point, and the connection between the two parts may not be directly connected, or may be made into a structure that is easy to bend, as long as folding can be achieved.

[0049] The main body 1, the first wing 2, the second wing 3 and the third wing 4 may be processed with folding indentations corresponding to a certain folding method, so that the intestinal tube 9 storage device can be folded along the folding indentations.

[0050] The intestinal tube storage device of the utility model forms a storage space with the first wing, the second wing and the third wing and the main body, which can gather and store the intestinal tube, so as to control the intestinal tube in a specific area of ​​the abdominal cavity to leave space for surgery. Secondly, the intestinal tube storage device can be folded to reduce the volume and placed into the human body through a small abdominal incision (an incision through which the specimen or organ passes through the human body wall), and then unfolded and used in the human body. It is easy to use and easy to operate. In the minimally invasive working mode, there is no need to occupy the poking hole. After the placement is completed, there is no need for personnel to hold and operate, and no human resources are occupied. Thirdly, the main body, the first wing, the second wing and the third wing are made of foldable flexible materials, which can reduce damage to the mesentery and the surface of the intestinal tube, and greatly improve the efficiency and safety of the operation.

[0051] The above are only some embodiments of the present invention. For those skilled in the art, without departing from the inventive concept of the present invention, several modifications and improvements can be made, or the above technical solutions can be freely combined, including the technical features between the above different embodiments, which all belong to the protection scope of the present invention.
