Description

Technical Field

[0001] The present invention relates to the field of medical devices and in particular to an intestinal post-operative protection device. Background Art

[0002] In the field of intestinal surgery, the quality of healing of the anastomosis or trauma site after surgery is directly related to the patient's recovery process and the risk of complications. At present, the common technical difficulties after intestinal surgery are that the intestinal tissue after surgical suture is in direct contact with digestive fluids, food residues and other intestinal fluids and excrement, which can easily cause local infection, inflammatory response or anastomotic fistula, leading to delayed healing or even surgical failure. Although postoperative fasting, anti-infective drugs or local irrigation are often used to assist recovery in clinical practice, these methods cannot directly isolate the physical stimulation and contamination of the anastomosis by intestinal fluids and excrement, and may increase the patient's pain and financial burden. Summary of the Invention

[0003] The purpose of the present invention is to provide a postoperative intestinal protective device that can isolate intestinal fluid, excrement, etc. from the anastomosis, thereby helping to improve the healing speed of postoperative wounds.

[0011] The fixing member includes a first clamping portion, a second clamping portion and a limiting member;

[0012] The first clamping portion and the second clamping portion can relatively clamp the raised portion;

[0013] The limiting member connects the first clamping portion and the second clamping portion, and the limiting member applies an external force on the first clamping portion and the second clamping portion to limit the first clamping portion and the second clamping portion to be in an open state; after the external force is removed, the first clamping portion and the second clamping portion are in a clamping state; or,

[0014] The fixing piece is a hollow annular structure with a clamping opening formed on the inner side; the clamping opening extends along the circumferential direction, and the cross section of the fixing piece is C-shaped.

[0015] Furthermore, the raised portion has side walls that are arranged opposite to each other, and a groove is formed inwardly on the side walls, and the clamping end of the fixing member can be embedded in the groove.

[0016] Furthermore, the fixing member is an embedding member that can be at least partially embedded in the raised portion.

[0017] Furthermore, the outer diameter of the raised portion is greater than 3 cm.

[0018] Furthermore, the raised portion has an end surface facing outward, the end surface is in an arc shape convex outward, and the end surface is parallel to the axis of the sausage casing.

For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0036] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] See Figures 1 to 3 The intestinal postoperative protection device shown in one embodiment of the present application is placed in the human body when in use to isolate the anastomosis 201 from intestinal fluid and excrement, thereby protecting the anastomosis 201. The intestinal postoperative protection device includes a device body 10 and a fixing member 20. The device body 10 includes a casing 11 and a raised portion 12, wherein the casing 11 is tubular and the raised portion 12 is integrally connected to the casing 11. The fixing member 20 is capable of fixing the raised portion 12 within the intestine 200, thereby fixing the device body 10 within the intestine 200.

[0038] For ease of understanding, the following describes the state of the intestinal postoperative protective device during actual use. When the intestinal postoperative protective device is not in use (i.e., not placed in the human body), the device body 10 and the fixing member 20 can be separated or connected, depending on the actual situation. During intestinal surgery, the device body 10 is placed in the intestine, the casing 11 extends along the extension direction of the intestine 200, the fixing member 20 is sheathed on the outside of the intestine 200, and the device body 10 is located in the upstream intestine of the intestinal tract cut into two sections. By adjusting the position, the casing 11 covers the anastomosis 201 on the inner side of the intestine 200, and then the fixing member 20 is clamped onto the raised portion 12. At this time, since the raised portion 12 is located on the inner side of the intestine 200 and the fixing member 20 is located on the outer side of the intestine 200, when the fixing member 20 is clamped onto the raised portion 12, the intestine 200 is clamped by the fixing member 20 and the raised portion 12 at the same time. In this way, the device body 10 is fixed in the intestine 200, and then the two sections of the intestine can be anastomosed by the anastomosis device. It should be noted that the flow direction of intestinal fluid and excrement in the intestine 200 ( Figure 1As shown in the direction indicated by arrow a in the middle, it has an upstream and downstream portion. Along the flow direction of intestinal fluid and excreta within the intestine 200, the fixing member 20 and the raised portion 12 are located upstream of the anastomotic opening 201, while the end of the dummy casing 11 away from the raised portion 12 is located downstream of the anastomotic opening 201. If the fixing member 20 and the raised portion 12 are referred to as the fixed position, the dummy casing 11 passes over the anastomotic opening 201 from the fixed position to cover it. In actual surgery, the end of the dummy casing 11 away from the raised portion 12 may be located outside the anus.

[0039] During intestinal surgery, the intestinal postoperative protection device can be placed in the intestine 200. After the anastomosis surgery is completed, the intestinal postoperative protection device is retained in the intestine. The anastomosis 201 is covered by the sausage-like casing 11, thereby preventing intestinal fluid and excrement in the intestine from directly contacting the anastomosis 201, thereby helping to improve the speed of postoperative wound healing.

[0040] In some embodiments, the fastener 20 is made of an absorbable material, eliminating the need for subsequent removal. The device body 10 is gradually absorbed by the body's tissues while the fastener 20 is being held in place. The device body 10 is no longer positioned at a specific location in the intestine 200 and can be expelled from the body through peristalsis and excretion of the intestine 200. Typically, 4-6 weeks after a rectal anastomosis, scar tissue at the anastomosis gradually matures, reaching a tensile strength approaching 70%-80% of that of a normal intestine 200. The anastomosis typically requires 3-6 months to fully recover, during which time the scar is stable, collagen remodeling is complete, and the anastomosis strength approaches normal levels. To accommodate the anastomotic recovery time, the fastener is preferably made of a synthetic material with an absorption period of approximately 60-90 days, such as polylactic acid (PLA) or polyglycolic acid (PGA).

[0041] In other embodiments, the device body 10 can be made of an absorbable material. Among them, the casing is a thin film sleeve with openings at the top and bottom, and the casing material is preferably polylactic acid-glycolic acid copolymer (PLGA) or polylactic acid-caprolactone copolymer (PLCL). In order to increase the healing speed of the anastomosis, the casing can be coated or added with drugs that accelerate wound healing, such as immunomodulators, antibiotics or chemotherapy drugs. The raised portion 12 can be made of a hard material or a flexible material. The hard material is made of a biodegradable metal or polymer material. The biodegradable metal can be an iron alloy or magnesium alloy, and the polymer material can be polylactic acid (PLA), polyglycolic acid (PGA), etc. The flexible material includes a flexible polymer material, such as polycaprolactone (PCL) and polylactic acid-caprolactone copolymer (PLCL). The raised portion and the casing can be formed integrally with the same material. The casing is a soft tubular object, not a film. The raised portion is formed by wrapping multiple layers of casing. The enteric casing 11 and the protrusion 12 can be connected by an absorbable medical adhesive, which includes α-cyanoacrylate, fibrin glue, polyethylene glycol (PEG)-based adhesive, etc. The above materials are only examples, and if better materials are developed with the development of absorbable materials, they should also be included.

[0042] In the above embodiment, if Figure 3 and Figure 6 As shown, the quasi-entericant casing 11 is secured within the intestinal 200 only upstream of the anastomosis 201 by the fastener 20 and the raised portion 12. The quasi-entericant casing 11 has a first end and a second end disposed opposite each other. After the quasi-entericant casing 11 is placed within the intestinal 200, the first end can be referred to as the upstream end 111, and the second end can be referred to as the downstream end 112. The raised portion 12 is located at or near the upstream end 111. To prevent the formation of a gap between the quasi-entericant casing 11 and the intestinal wall 202, thereby preventing intestinal fluid and excreta from being retained between the quasi-entericant casing 11 and the intestinal wall 202, the raised portion 12 should be positioned as close to the upstream end 111 as possible.

[0043] The raised portion may be located outside the quasi-entercise casing. Specifically, when the quasi-entercise casing is placed in the intestine, the raised portion is located between the quasi-entercise casing and the intestine. When intestinal fluid and excreta enter the quasi-entercise casing from the intestine, the fluid and excreta primarily flow into the quasi-entercise casing, thereby reducing the amount of fluid and excreta retained in the gap between the raised portion and the quasi-entercise casing.

[0044] In another embodiment, the sausage-like casing may also include a support frame and a membrane covering the support frame. The structure of this sausage-like casing can be similar to intestinal stents in the prior art, with the raised portion bonded to the support frame via solder. The support frame can apply pressure to the membrane, causing it to adhere to the intestinal wall, further securing the intestine and preventing gaps between the sausage-like casing and the intestinal wall that could allow intestinal fluids and excreta to circulate. The support frame can be made of the same absorbable synthetic material as the raised portion. The support frame and raised portion can be integrally formed or secured via a medical adhesive.

[0045] Please combine Figure 1 and Figure 3 The raised portion 12 is an annular structure. The outer diameter of the raised portion 12 is larger than the inner diameter of the intestine 200. The inner diameter of the rectum of an adult is generally 3 cm. Therefore, the outer diameter of the raised portion 13 is larger than 3 cm. In actual applications, the inner diameter of the clamping ring 10 is set to be larger than 3 cm and smaller than 4 cm. Such a setting allows the raised portion 12 to stretch the intestine 200 outward when the device body 10 is placed in the intestine, so as to facilitate clamping by the fixing member 20. The raised portion 12 has an end face 121 facing outward, specifically, the end face 121 faces the intestinal wall 202. The end face 121 is in an outwardly convex arc shape. By setting the end face 121 in an outwardly convex arc shape, it is possible to prevent the raised portion 12 from piercing or puncturing the intestinal wall 202. Of course, in other embodiments, the end face 121 may not be an arc shape, such as a multi-segment wave structure, or a cone with an arc top. The raised portion 12 actually needs to be passivated.

[0046] In other embodiments, the raised portion 12 may also be located on the inner side of the sausage casing 11 . In this case, the raised portion 12 is usually located at the upstream end 111 for easy fixation.

[0047] See Figure 4 The raised portion 12 may not be a ring-shaped structure, but may be composed of a plurality of arc-shaped blocks. Specifically, the number of the raised portions 12 is at least two, and at least two arc-shaped blocks are arranged at equal intervals along the circumferential direction.

[0048] In some embodiments, the fixing member 20 may be a clamping structure, which may clamp the protrusion 12 in its clamping cavity 26 or be clamped on the side wall of the protrusion 12 through the clamping structure.

[0049] In one alternative embodiment, please combine Figures 1 to 3The fixing member 20 includes a first clamping portion 21 and a second clamping portion 22 for clamping the raised portion 12. The first clamping portion 21 and the second clamping portion 22 are connected to form a resilient C-shaped structure. The first clamping portion 21 and the second clamping portion 22 form a clamping cavity 26, and the raised portion 12 is restrained within the clamping cavity 26 by the first clamping portion 21 and the second clamping portion 22. The ends of the first clamping portion 21 and the second clamping portion 22 do not abut the upper and lower side walls of the raised portion 12.

[0050] In another alternative embodiment, please combine Figure 5 and Figure 6 The raised portion 12 has an upper side wall 122 and a lower side wall 123 that are arranged opposite to each other. The ends of the first clamping portion 21 and the second clamping portion 22 are clamped (held against) on the upper side wall 122 and the lower side wall 123. In this embodiment, in order to prevent the fixing member 20 from falling off, a groove 124 is formed on the upper side wall 122 and the lower side wall 123, and the clamping ends of the first clamping portion 21 and the second clamping portion 22 are embedded in the groove 124.

[0051] In this embodiment, the raised portion 12 forms a closed ring, so the first clamping portion 21 and the second clamping portion 22 are clamped on the upper side wall 122 and the lower side wall 123. As mentioned above, if the raised portion 12 is composed of a plurality of arc-shaped blocks, Figure 4 , then, the raised portion 12 also has a left side wall 125 and a right side wall 126 arranged opposite to each other, and the first clamping portion and the second clamping portion can be clamped on the left side wall 125 and the right side wall 126 respectively. Similarly, a groove 124 can be formed on the left side wall 125 and the right side wall 126.

[0052] To facilitate the fixing member 20 to clamp the raised portion 12, the raised portion 12 can be configured as a flat structure, with the radial width of the raised portion 12 being greater than its thickness, thereby facilitating clamping. Specifically, when the first clamping portion 21 and the second clamping portion 22 clamp the upper and lower walls, respectively, the thickness direction of the raised portion 12 corresponds to the arrangement direction of the upper and lower walls; when the first clamping portion 21 and the second clamping portion 22 clamp the left and right walls, respectively, the thickness direction of the raised portion 12 corresponds to the arrangement direction of the left and right walls.

[0053] In another alternative embodiment, please refer to Figure 7The fixing member 20 includes a first clamping portion 21, a second clamping portion 22, and a first force-applying portion 23 and a second force-applying portion 24 connected to the first clamping portion 21 and the second clamping portion 22, respectively. The first clamping portion 21 and the second clamping portion 22 are connected to form a clamping cavity 26, and the first clamping portion 21 and the second clamping portion 22 can relatively clamp the protrusion 12. The first force-applying portion 23 and the second force-applying portion 24 drive the first clamping portion 21 and the second clamping portion 22 to move relative to each other under the action of an external force. The structure of the fixing member 20 can be similar to that of a dovetail clamp.

[0054] In another alternative embodiment, please combine Figure 8 The fixing member 20 includes a first clamping portion 21, a second clamping portion 22 and a limiting member 25. The first clamping portion 21 and the second clamping portion 22 are connected to form a clamping cavity 26, and the first clamping portion 21 and the second clamping portion 22 can relatively clamp the protrusion 12. The limiting member 25 connects the first clamping portion 21 and the second clamping portion 22, and the limiting member 25 applies an external force on the first clamping portion 21 and the second clamping portion 22 to limit the first clamping portion 21 and the second clamping portion 22 to be in an open state; after the external force is removed, the first clamping portion 21 and the second clamping portion 22 are in a clamping state. In this embodiment, the fixing member 20 also includes a first force applying portion 23 and a second force applying portion 24 for applying an external force, and the first clamping portion 21, the second clamping portion 22, the first force applying portion 23 and the second force applying portion 24 form a structure similar to a dovetail clamp. The limiting member 25 can be a strip-shaped body, which is bound to the first force-applying portion 23 and the second force-applying portion 24. The strip-shaped body can be directly cut by surgical scissors to improve operability. In addition, the limiting member 25 can also be a detachable clip for clamping on the first force-applying portion 23 and the second force-applying portion 24.

[0055] In the embodiment described above, when the ends of the first and second clamping portions are not clamped (abutted) against the sidewalls of the raised portion, in the clamped state, the first and second clamping portions 21 and 22 form a first clamping distance that is slightly smaller than the sum of the thicknesses of the two layers of intestinal tissue 200 in a relaxed state and slightly larger than the sum of the thicknesses of the two layers of intestinal tissue 200 in a minimally compressed state. This arrangement prevents necrosis of the clamped tissue.

[0056] In the embodiment where the ends of the first and second clamping portions are clamped against the sidewalls of the raised portion, in the clamped state, the first and second clamping portions 21 and 22 form a first clamping distance. This first clamping distance is slightly smaller than the sum of the thickness of the two layers of intestinal tissue 200 in a relaxed state and the thickness of the raised portion 12, and slightly larger than the sum of the thickness of the two layers of intestinal tissue 200 in a minimally compressed state and the thickness of the raised portion 12. The thickness direction of the raised portion 12 is the clamping direction of the first and second clamping portions 21 and 22. This design also prevents necrosis of the clamped tissue.

[0057] Please combine Figure 8 The fixing member 20 can also be a hollow ring with a clamping opening 27 formed on its inner side. The clamping opening extends in the circumferential direction, and the cross-section of the fixing member is C-shaped. The fixing member 20 has clamping ends 271 located on both sides of the clamping opening 27. The fixing member 20 can be clamped in its clamping cavity by clamping the protrusion, or the clamping ends 271 can be embedded in the groove 124. To facilitate the installation of the fixing member 20, the fixing member 20 has a certain elasticity in the radial direction. Under the action of external force, the radial diameter can be correspondingly enlarged. After the external force is removed, the radial diameter returns to its original size. The following is an example of an embodiment in which the fixing member 20 clamps the protrusion in the clamping cavity to explain the assembly: other surgical instruments are used to apply an outward pulling force on the fixing member 20, so that the fixing member 20 is radially expanded and then positioned outside the protrusion, with the clamping opening 271 facing the protrusion; when the external force is removed, the fixing member 20 slowly returns to its original size. During the recovery process, the protrusion will first abut against the clamping opening 271. Under the relative force of the protrusion, the clamping opening 271

[0058] It gradually opens until the raised portion gradually enters the clamping cavity through the clamping opening 271 . When the raised portion completely enters the clamping cavity, the clamping opening 271 returns to its original state, and the raised portion is restricted in the clamping cavity by the clamping end 271 .

[0059] Alternatively, in another embodiment, the fixing member 20 is an embedding member that can be fully or partially embedded in the raised portion 12 , and the embedding member can be a structure such as a suture staple or a screw.

[0060] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
