Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically to an expansion storage device for intestinal resection surgery. Background Technology

[0002] Colonoscopy is a commonly used instrument in intestinal surgery, primarily used to remove polyps or tumors in the intestines. During the procedure, it is essential to minimize the surgical time to reduce the risk of complications and intestinal spasms. Currently, colonoscopic resection surgery often involves directly inflating the intestines with a colonoscope to open them and expose the surgical field. This method is particularly prone to causing intestinal spasms. Furthermore, when there are many polyps in the patient's intestines, each polyp removal requires repeated insertion and removal, increasing the surgical time and affecting the surgical outcome. Therefore, improvements are needed. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an expansion storage device for intestinal resection surgery, which can support the intestine and simplify the operation process to reduce the operation time.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] An expansion storage device for intestinal resection surgery includes two elastic sheets arranged in a cross configuration. One end of the two elastic sheets is connected to each other, and a storage space is formed between the two elastic sheets. The storage space has an opening corresponding to the free end of the two elastic sheets. The free ends of the two elastic sheets are bent inward to form an arc-shaped compression section. The arc-shaped section is provided with a clamping section that is recessed towards the storage space. When the two clamping sections are clamped, the two compression sections abut against each other and deform towards the storage space.

[0006] A protective film, which is made of an elastic material and is used to wrap an elastic sheet.

[0007] As a further improvement of the present invention, the elastic sheet further includes a protective section and a connecting section. The protective section is inclined relative to the connecting section. The two ends of the protective section are respectively connected to the connecting section and the clamping section. The two connecting sections are connected to each other and are used to keep the two protective sections parallel to each other.

[0008] As a further improvement of the present invention, the spacing between the two protection segments is adjustable.

[0009] As a further improvement of the present invention, the two connecting segments are staggered, and each of the two connecting segments is provided with a positioning unit and a plurality of positioning points. The plurality of positioning points are arranged along the height direction, and the positioning unit is used to connect with the positioning points to fix the two connecting segments to each other.

[0010] As a further improvement of the present invention, the positioning unit is a connecting column made of elastic material. One end of the connecting column is connected to the connecting segment, and the other end forms a hemispherical limiting block. The connecting segment forms a connecting hole corresponding to the positioning point. The connecting column is used to drive the limiting block through the connecting hole and fix it to the connecting segment.

[0011] As a further improvement of the present invention, the protective film includes a covering area disposed on both sides of the corresponding elastic sheet, the covering area being used to cover and seal both sides of the storage space.

[0012] As a further improvement of the present invention, the protective film is provided with a traction belt corresponding to the clamping section, and multiple holes are arranged on the traction belt.

[0013] The beneficial effects of this invention are:

[0014] 1. The two cross-set elastic sheets can effectively expand the intestine to avoid obstructing the surgical field during operation. At the same time, the overall structure is simple and can be directly inserted into the intestine through the colonoscope for easy operation.

[0015] 2. The storage space and opening design allow for the collection of polyps or tumors removed during surgery, eliminating the need for instruments to be withdrawn and significantly reducing surgical time.

[0016] 3. The inward bending of the arc-shaped extrusion section can restrain the tissue within the storage space, thereby reducing the risk of the tissue falling out of the storage space during use.

[0017] 4. The clamping section, combined with the arc-shaped compression section, allows the device to be moved directly by the clamps during colonoscopy. During clamping, the compression section deforms naturally under force, bending into the storage space to compact the tissue. This increases the storage capacity of the storage space and keeps the opening closed during movement, further reducing the risk of tissue loss. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals.

[0023] like Figure 1-3 As shown, the expansion storage device for intestinal resection surgery includes two elastic sheets 1 arranged in a cross configuration. One end of the two elastic sheets 1 is connected to each other, and a storage space 2 is formed between the two elastic sheets 1. The storage space 2 forms an opening 3 corresponding to the free end of the two elastic sheets 1. The free ends of the two elastic sheets 1 are bent inward to form an arc-shaped compression section 4. The arc-shaped section is provided with a clamping section 5 that is recessed towards the storage space 2. When the two clamping sections 5 are clamped, the two compression sections 4 abut against each other and deform towards the storage space 2.

[0024] Preferably, it also includes a protective film 6, which is made of an elastic material and is used to wrap the elastic sheet 1.

[0025] During use, the clamping section 5 is held by the clamps, causing the two compression sections 4 to deform against each other. At this time, the entire device is in a closed state. Then, the clamps are used to enter the end of the intestinal surgical area through the main channel of the colonoscope. The clamps are then released, and the two elastic plates 1, driven by their own elasticity, cause the two compression sections 4 to separate. The opening 3 opens and faces the surgical instruments. At the same time, the separated elastic plates 1 can expand the intestine at this location to expose the surgical field for medical staff to operate. After the medical staff removes the tissue, the tissue can be placed into the storage space 2 through the opening 3 to achieve the effect of temporary tissue storage. After the area is removed, the clamping section 5 is held by the clamps, causing the compression sections 4 to deform naturally. Thus, while closing the device, the deformation of the compression sections 4 can compact the tissue in the storage space 2, thereby minimizing the risk of tissue falling out during use. The device is then moved to the next surgical area with the clamps to complete the expansion of the entire intestine and the collection of the removed tissue.

[0026] At the same time, since the extrusion section 4 is arc-shaped and bends towards the storage space 2, it can reduce the opening 3 to achieve the effect of preventing the tissue from falling out of the storage space 2, that is, reducing the risk of tissue falling out of the storage space 2.

[0027] Meanwhile, since the clamping section 5 is located on the squeezing section 4 and bends towards the storage space 2, the squeezing section 4 can be given a greater range of motion through the clamping section 5, so as to facilitate the instrument to open the opening 3 to put the tissue into the storage space 2.

[0028] Preferably, the elastic sheet 1 further includes a protective section 7 and a connecting section 8. The protective section 7 is inclined relative to the connecting section 8. The two ends of the protective section 7 are respectively connected to the connecting section 8 and the clamping section 5. The two connecting sections 8 are connected to each other and are used to keep the two protective sections 7 parallel to each other.

[0029] By tilting the protective section 7 and the connecting section 8, the protective section 7 can be parallel, thereby greatly reducing the pressure on the intestine when it is stretched, thus reducing the stimulation of the intestine. At the same time, the parallel protective section 7 can also work with the protective film 6 to simulate the effect of feces, thereby further reducing the stimulation of the intestine and reducing the risk of intestinal spasm.

[0030] Preferably, the spacing between the two protection segments 7 is adjustable.

[0031] By adjusting the spacing between the two protection segments 7, it is possible to adapt to the use of different segments of the intestine, thereby improving the overall practicality.

[0032] Preferably, the two connecting segments 8 are staggered, and each of the two connecting segments 8 is provided with a positioning unit 9 and a plurality of positioning points 10. The plurality of positioning points 10 are arranged along the height direction, and the positioning unit 9 is used to connect with the positioning points 10 so that the two connecting segments 8 are fixed to each other.

[0033] The interlocking of connecting segments 8 allows for easy manual adjustment by medical staff in conjunction with the connection of positioning unit 9 and positioning point 10.

[0034] Preferably, the positioning unit 9 is a connecting post 11 made of elastic material. One end of the connecting post 11 is connected to the connecting segment 8, and the other end forms a hemispherical limiting block 12. The connecting segment 8 forms a connecting hole 13 corresponding to the positioning point 10. The connecting post 11 is used to drive the limiting block 12 through the connecting hole 13 and fix it to the connecting segment 8.

[0035] The positioning method using limit block 12, connecting post 11 and connecting hole 13 makes the overall structure more streamlined, thereby reducing the overall volume and lowering the cost of use.

[0036] Preferably, the protective film 6 includes a covering area 14 disposed on both sides of the elastic sheet 1, the covering area 14 being used to cover and seal both sides of the storage space 2.

[0037] This allows the storage space 2 to have an opening 3 that connects it to the outside world, thus ensuring the temporary storage effect of the tissues within the storage space 2.

[0038] Preferably, the protective film 6 is provided with a traction belt 15 corresponding to the clamping section 5, and multiple holes 16 are arranged on the traction belt 15.

[0039] The traction belt 15 and the hole 16 facilitate clamping. Since the clamping area between the clamping section 5 and the clamp will shrink when the clamp is at the end, the hole 16 can greatly improve the stability of the clamp during clamping.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention.
