Description

Technical Field

[0001] The present disclosure specifically discloses a double-annular anastomotic device. Background Art

[0002] End-to-end anastomosis of the intestinal tract is a routine surgical procedure in clinical practice. End-to-end anastomosis can restore the continuity of the intestinal tract and is the most consistent anastomosis method with normal physiological structure. Currently, the methods for achieving end-to-end anastomosis of the intestinal tract mainly include the following: one is anastomosis with a tubular stapler; the second is surgical suture; and the third is magnetic adsorption anastomosis. In clinical use, the existing methods of end-to-end anastomosis of the intestinal tract have the following defects, including:

[0003] The anastomosis with a tubular stapler requires the stapler body to be placed in one side of the intestinal tube. If it is close to the anus, it is inserted through the anus; if it is far from the anus, the stapler body needs to be lengthened. If the anastomosis still cannot be completed, an end-to-side anastomosis is required. The stapler body needs to be placed through the broken end of the severed intestinal tube, pass through the side wall of the intestinal tube, align with the anvil side, and then the anastomosis is triggered. The stump entering the stapler body is then closed separately. Its disadvantages are: it wastes part of the intestinal tube and is difficult to use when the intestinal length is insufficient; the stump needs to be closed again, forming two closed intestinal openings, which increases the risk of leakage; after the stump entering the stapler body is closed, a blind end is formed, which is inconsistent with the normal physiological morphology; after the tubular stapler is fired, the original [type anastomotic staple is required, which is squeezed to form a B type, and the squeezing force required is relatively high. In addition, the disadvantages of manual suturing are: high technical requirements, which require long-term learning and mastering, unstable anastomosis, uneven stitches or different knotting forces, which make it difficult to ensure the quality of the anastomosis and high risk of anastomotic leakage. Magnetic adsorption anastomosis is a newly invented anastomosis method that completes the anastomosis by adsorption of two magnetic rings. However, its effectiveness is uncertain and its application is very limited. In summary, there is an urgent need to optimize and improve the existing end-to-end intestinal anastomosis method. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, the present application aims to provide a double-ring anastomosis device that can achieve end-to-end anastomosis of the intestinal tract simply and efficiently compared with the prior art.

[0013] According to the technical solution provided in the embodiment of the present application, the annular opening on the annular excitation track close to the abutting ring is covered with a protective film.

[0014] According to the technical solution provided in the embodiment of the present application, a docking auxiliary ring is embedded in the inner wall of the anastomotic ring and docking auxiliary blocks are provided in a circular array on the outer wall of the docking auxiliary ring relatively close to one end of the abutting ring; the inner wall of the abutting ring is provided with a docking auxiliary rail that matches the docking auxiliary block.

[0016] In summary, the present application discloses a double-annular anastomosis device. This technical solution is based on the design of an anastomosis activation component and an anastomosis abutment component, which are respectively matched with the two ends of the intestinal tube, so that the edges of the intestinal tube ends are respectively close to the centers of the anastomosis ring and the abutment ring. Then, the two anastomosis rings covering the intestinal tube ends and the abutment ring are abutted, and the activation ring is activated. When the activation ring moves along the annular activation track toward the abutment ring, the anastomosis staples gradually enter the abutment track and are finally clamped with the bottom of the abutment track, so that the anastomosis ring and the abutment ring are tightly fixed. Based on this design, the structural design of the double-ring anastomosis device can conveniently anastomose the broken ends of the intestinal tube. Compared with the tubular anastomosis device, it can be adapted to a variety of occasions. During use, it can minimize the waste of the intestinal tube and does not require a large excitation force. In addition, due to its annular structure, it conforms to the normal physiological morphology and is not prone to intestinal leakage. Compared with manual suturing, it is easy to operate, does not require long-term learning, and the anastomosis state is stable, which is suitable for popularization and use.

[0027] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] Please refer to Figure 1 A specific embodiment of a double-annular anastomotic device is shown.

[0030] Figure 1 The double-annular anastomosis device described in the invention comprises: an anastomosis excitation assembly 10, which comprises: an anastomosis ring 11 and an excitation ring 12 embedded in one end of the anastomosis ring 11 and capable of moving axially thereof; an anastomosis ring 11 is provided with an annular excitation track 13 for the excitation ring 12 to move; an anastomosis staple 14 is fixedly connected to one end of the excitation ring 12 that enters the annular excitation track 13 and when not excited, the anastomosis staple 14 is hidden in the annular excitation track 13; an anastomosis abutment assembly 20, which comprises: an abutment ring 21; an annular abutment track 22 is provided at one end of the abutment ring 21 corresponding to an annular opening on the excitation track 13 that is relatively far away from one end of the excitation ring 12; when the excitation ring 12 moves along the annular excitation track 13 in a direction close to the abutment ring 21, the anastomosis staple 14 enters the abutment track 22 and is clamped with the bottom of the abutment track 22, so that the anastomosis ring and the abutment ring 21 are tightly fixed.

[0031] Figure 1 The anastomosis excitation component 10 includes: an anastomosis ring 11 and an excitation ring 12 embedded in one end of the anastomosis ring 11 and capable of moving along its axial direction; an annular excitation track 13 is provided in the anastomosis ring 11 for the excitation ring 12 to move; an anastomosis staple 14 is fixedly connected to one end of the excitation ring 12 that enters the annular excitation track 13 and when not excited, the anastomosis staple 14 is hidden in the annular excitation track 13.

[0032] in:

[0033] The anastomotic ring 11 is an annular structure as a whole, and has two annular end walls with an annular excitation track 13 running through the two annular end walls.

[0034] The excitation ring 12 is an annular structure, one end of which is embedded in the excitation track and a staple 14 is fixed to the end entering the excitation track. In the initial state, the excitation ring 12 can be stably set in the excitation track, so that the staple 14 is hidden in the annular excitation track 13, which can prevent the staple from leaking out and causing accidental injury to others or the intestinal wall. Specifically, the annular excitation track includes: an entry section 131 distributed along the axial direction of the stapler and an excitation section 132 connected to the entry section. The entry section and the excitation section also have an annular structure and the wall thickness of the entry section is smaller than the wall thickness of the excitation section. Optionally, the end of the staple is provided with a barb-like structure. The staples are distributed in an annular array at one end of the excitation ring, and the single-position staples can include at least two parallel-arranged single staples. Accordingly, a single hole is provided at the bottom of the abutment track to match the single staple.

[0035] In the initial state, the end of the excitation ring member that enters the excitation track is stably engaged with the entry section, so that the staples 14 are hidden in the annular excitation track 13. When excitation is required, the excitation ring member 12 is pushed along the annular excitation track 13 toward the abutment ring member 21, and the excitation ring member 12 breaks through the restriction of the entry section 131 and gradually enters the excitation section 132, and the staples are gradually exposed outside the annular excitation track. Optionally, the wall thickness of the entry section on the excitation track is less than the wall thickness of the excitation section on the excitation track. Accordingly, in the initial state, the end of the excitation track that extends into the entry section has the same wall thickness as the entry section or slightly greater than the wall thickness of the entry section track. The purpose is to use the entry section to stably fix the excitation ring member before use, ensuring that the staples 14 are hidden in the annular excitation track 13 in the initial state. Optionally, the excitation ring member includes: a clamping section that cooperates with the entry section and a traveling section that is an integral structure with the clamping section. The wall thickness of the traveling section is smaller than that of the clamping section; in the initial state, the clamping section is firmly clamped with the entry section. When the clamping section cooperates with the entry section and enters the excitation section under the action of external force, the traveling section can slide smoothly along the entry section and the excitation section in turn.

[0036] The anastomosis abutment assembly 20 comprises: an abutment ring 21; one end of the abutment ring 21 is provided with an annular abutment track 22 corresponding to the annular opening on the excitation track 13 which is relatively far away from one end of the excitation ring 12; specifically, an annular opening is provided on the annular abutment track at one end which is relatively close to the anastomosis excitation assembly. When the anastomosis excitation assembly 10 and the anastomosis abutment assembly 20 are in abutment, after the excitation ring is started, the excitation ring 12 is pushed to move along the annular excitation track 13 toward the abutment ring 21. The excitation ring 12 breaks through the restriction of the entry section and enters the excitation section. The anastomosis staples 14 gradually enter the abutment track 22 and are finally clamped with the bottom of the abutment track 22, so that the anastomosis ring and the abutment ring 21 are tightly fixed.

[0037] This technical solution is based on the design of the anastomosis excitation component and the anastomosis abutment component, and the two are respectively matched with the two broken ends of the intestinal tube, so that the edges of the broken ends of the intestinal tube are respectively close to the center of the anastomosis ring and the abutment ring, and then the two anastomosis rings and the abutment rings covering the broken ends of the intestinal tube are abutted, and the excitation ring is started. When the excitation ring moves along the annular excitation track toward the abutment ring, the anastomosis staples gradually enter the abutment track and are clamped with the bottom of the abutment track, so that the anastomosis ring and the abutment ring are tightly fixed.

[0038] Based on this design, the structural design of the double-ring anastomosis device can conveniently anastomose the broken ends of the intestinal tube. Compared with the tubular anastomosis device, it can be adapted to a variety of occasions. During use, it can minimize the waste of the intestinal tube and does not require a large excitation force. In addition, due to its annular structure, it conforms to the normal physiological morphology and is not prone to intestinal leakage. Compared with manual suturing, it is easy to operate, does not require long-term learning, and the anastomosis state is stable, which is suitable for popularization and use. Compared with magnetic adsorption, it has a clear effect and is more suitable for large-scale promotion and use.

[0039] In a preferred embodiment, an anti-dropping pinhole 221 capable of engaging with the free end of the anastomosis staple 14 is provided on the inner bottom of the annular abutment track 22 .

[0040] Please refer to Figure 1 As shown, Figure 1 In order to secure the staples to the bottom end of the annular abutment track 22, the inner bottom plate of the annular abutment track 22 is provided with an anti-dropout pinhole 221 for the staples 14 to enter. Optionally, the anti-dropout pinhole 221 includes: a first columnar channel 2211 for guiding the staples in, and a second channel 2212 connected to the first channel 2211 and in an inverted cone shape. The diameter of the bottom of the cone of the second channel is larger than the diameter of the first channel, that is, an annular step is formed between the second channel and the first channel. When the staples enter the second channel along the first channel, the inverted teeth on the staples engage with the annular step, preventing the staples from falling out of the annular abutment track.

[0041] In a preferred embodiment, the end of the anastomotic ring relatively close to the abutting ring 21 is further provided with a first clamping groove 15 arranged in the annular excitation track 13; the first clamping groove 15 can be equipped with an independently arranged first clamping member 30.

[0042] Please refer to Figure 2a The schematic diagram of the structure of the anastomotic ring and the first pressing member cooperating with each other is shown. Figure 2a In the embodiment, the first pressing groove is annular and is provided at one end of the anastomotic ring relatively close to the abutting ring 21. Figure 2bThe height of the first pressing groove is 1 / 3 of the annular excitation track. Optionally, a plurality of first inner slots 151 arranged in an annular manner are provided in the first pressing groove 15, and a first inner clamping member 31 is provided at one end of the first pressing member 30 that enters the first inner slot 151 and is matched with the first inner slot 151.

[0043] The anastomotic ring is provided with a first clamping groove and the first internal clamping piece can be matched in the first clamping groove, so that the edge of the intestinal end is moved closer to the center of the anastomotic ring, and then the first internal clamping piece is used to press the intestinal end into the first clamping groove. The first internal clamping piece and the first clamping groove can be used to fix the intestinal end to the anastomotic replacement piece, which is beneficial to the subsequent anastomotic operation process.

[0044] In a preferred embodiment, the end of the abutment ring 21 relatively close to the anastomotic ring is further provided with a second clamping groove 23 arranged in the annular abutment track 22; the second clamping groove 23 can be equipped with an independently arranged second clamping member 40.

[0045] Please refer to Figure 3a The schematic diagram of the structure of the abutment ring 21 and the second pressing member 40 cooperating with each other is shown in FIG3. In FIG3, the second pressing groove is an annular structure, which is provided at one end of the abutment ring relatively close to the anastomotic ring. Optionally, the height of the second pressing groove is 1 / 3 of the annular abutment track 22. Optionally, please refer to Figure 3b A plurality of second inner slots 231 arranged in an annular manner at intervals are defined in the second pressing groove 23 , and a second inner clamping member 41 is provided at one end of the second pressing member 40 that enters the second inner slot 231 and is matched with the second inner slot 231 .

[0046] The abutment ring is provided with a second clamping groove and the second inner clamping piece can be matched in the second clamping groove, so that the edge of the intestinal end is moved closer to the center of the abutment ring, and then the second inner clamping piece is used to press the intestinal end into the second clamping groove. The second inner clamping piece and the second clamping groove can fix the intestinal end to the abutment ring, which is beneficial to the subsequent anastomosis process.

[0047] Please refer to Figure 4 The structural diagram of the double-ring anastomosis device shown in FIG. 1 shows that, in a preferred embodiment, an identification capsule 50 is embedded on one end of the abutment ring 21 which is relatively far away from the anastomosis ring, and the identification capsule 50 enters one end of the abutment ring 21 and enters the anti-falling needle hole 221.

[0048] Specifically, the anti-dropping pinhole includes: a columnar first channel and a second channel connected to the first channel, the second channel has a conical structure, the top diameter of the cone is larger than the diameter of the first channel, and an annular step is formed between the first channel and the second channel.

[0049] When the staple enters the annular abutment track, it continues to enter the first channel and contacts the marking capsule, puncturing the marking capsule, indicating that the staple has been stably and reliably clamped with the annular step, that is, the anastomosis operation process is reliably completed.

[0050] Please refer to Figure 5 In a preferred embodiment, the annular opening of the annular excitation track 13 near the abutment ring 21 is covered with a protective film 16. The design of the protective film can prevent the leakage of staples and cause accidental injury to others or the intestinal wall; on the other hand, it can effectively protect the staples from medical use and prevent dust from entering.

[0051] Please refer to Figure 6 In a preferred embodiment, a docking auxiliary ring 17 is embedded in the inner wall of the anastomotic ring 11, and a docking auxiliary block is provided in a circular array on the outer wall of the docking auxiliary ring 17 relatively close to one end of the abutting ring 21; the inner wall of the abutting ring 21 is provided with a docking auxiliary rail 211 that matches the docking auxiliary block.

[0052] Optionally, the docking auxiliary ring 17 is a columnar structure, and one end thereof relatively close to the first compression groove is exposed outside the anastomotic ring, and docking auxiliary blocks distributed in a ring array are provided on a section of the outer wall of the docking auxiliary ring exposed outside the anastomotic ring.

[0053] When the anastomotic ring and the abutting ring are matched, the docking auxiliary block enters the docking auxiliary rail along the axial direction. When the anastomotic ring and the abutting ring are matched end to end, the docking auxiliary block is stably engaged with the docking auxiliary rail.

[0054] In order to facilitate reliable docking between the anastomotic ring and the abutment ring, a docking auxiliary ring is embedded in the inner wall of the anastomotic ring and docking auxiliary blocks are arranged in a circular array on the outer wall of the docking auxiliary ring relatively close to one end of the abutment ring; the inner wall of the abutment ring is provided with a docking auxiliary rail that matches the docking auxiliary block.

[0055] When the anastomotic ring and the abutting ring are docked, the docking auxiliary ring enters the abutting ring, and the docking auxiliary block enters the docking auxiliary rail, which can achieve a preliminary positioning effect. Even if the initial positioning is not accurate, the anastomotic ring or the abutting ring can be slightly rotated until the docking auxiliary block enters the docking auxiliary rail. This can also achieve a positioning effect, ensuring that the anastomotic staples enter the pinholes after entering the abutting rails.

[0056] Optionally, the docking auxiliary block is V-shaped and the docking auxiliary rail 211 is also V-shaped. The V-shaped docking auxiliary rail has a large top opening, which is convenient for the docking auxiliary block to enter therein, so that the operator can quickly find the entry position during operation.

[0057] Even if there is a slight misalignment during the docking process, due to the design of the V-shaped structure, after the docking auxiliary block contacts the inner wall of one side of the docking auxiliary rail, the matching ring can be slightly rotated or the abutment ring can be slightly adjusted to slightly adjust the corresponding positions of the docking auxiliary block and the docking auxiliary rail, ensuring fast and accurate docking.

[0058] Optionally, in a specific application, in any of the above embodiments, except for the anastomotic staples and the bottom of the abutment track 22, the remaining materials can be designed to be medical absorbable materials.

[0059] Specifically, when the bottom of the abutting track 22 is designed with the anti-dropping pinhole 221 , the first hole and the second hole of the anti-dropping pinhole 221 are also made of non-absorbable material.

[0060] The above description is merely a preferred embodiment of the present application and an illustration of the technical principles employed. Those skilled in the art should understand that the scope of the invention herein is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but also encompasses other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the inventive concept. For example, a technical solution formed by replacing the above-mentioned features with (but not limited to) technical features having similar functions disclosed in this application.
