Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a laparoscopic surgical incision sealing and isolation device. Background Art

[0002] Laparoscopic surgery is an important means of modern tumor surgical treatment. Compared with traditional surgery, it has significant advantages such as less surgical trauma, faster postoperative recovery, and shorter hospital stay. Laparoscopic tumor resection surgery requires the removal of tumor specimens through an abdominal incision, which is shorter than that of open surgery. After removing the specimen, in most cases, it is still necessary to re-establish the pneumoperitoneum state and perform laparoscopic anastomosis, flushing, strict hemostasis, and drainage placement. In order to temporarily form a closed abdominal environment to reconstruct pneumoperitoneum, surgeons often use self-made incision closure devices, such as using different types of elastic sterile surgical latex gloves to temporarily close the incision. The above-mentioned incision closure operation has many disadvantages, such as: laparoscopic pneumoperitoneum pressure is relatively high, and there are certain requirements for latex quality. In actual operation, latex gloves have been torn; if it is necessary to insert the scope through the incision for further exploration, a small hole needs to be cut on the glove, and the size is often difficult to grasp, resulting in a large opening and serious air leakage, which significantly affects the surgical process and prolongs the operation time. Therefore, there is an urgent need for a laparoscopic surgical incision closure device that can temporarily close the abdominal cavity when needed, which is convenient for medical staff to use while minimizing the cost of the patient, while saving surgical time and ensuring the safe and smooth progress of the surgery.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] This embodiment provides a laparoscopic surgical incision sealing and isolation device, such as Figures 1 to 13As shown, it includes an elastic sleeve 1 and a closing cap 2. The two ends of the elastic sleeve 1 are respectively provided with a first opening and a second opening. The first opening is coaxially fixed with an elastic anti-slip ring 101. The elastic anti-slip ring 101 can be elastically deformed when under pressure, which is conducive to being inserted into the interior of the abdominal incision 3. However, after it recovers its original shape, it can also play an anti-slip effect, so its texture is not too soft. The second opening is coaxially fixed with a rigid connecting ring 102, which is harder and convenient to maintain its shape so as to be connected with the closing cap 2. The closing cap 2 includes a closing cover plate 201, and an operating exhaust port 202 is provided on the closing cover plate 201. A duckbill valve 203 and a first connecting member are provided on one of the plate surfaces of the closing cover plate 201, and the first connecting member is used to be detachably connected to the rigid connecting ring 102. The duckbill valve 203 is connected to the operating exhaust port 202. A second connecting member is provided on the other plate surface of the closing cover plate 201, and the second connecting member is also used for detachably connecting the rigid connecting ring 102. Therefore, there are two connection directions between the closing cap 2 and the elastic sleeve 1, namely, positive buckle and reverse buckle. The first connecting member and the rigid connecting ring 102, the closing cover plate 201 closes the second opening, and the duckbill valve 203 extends into the second opening. This is a positive buckle method. When the second connecting member is connected to the rigid connecting ring 102, the closing cover plate 201 closes the second opening, and the duckbill valve 203 faces away from the second opening. This is a reverse buckle method. In the positive buckle method, the flow direction of the duckbill valve 203 is from outside to inside, and the intra-abdominal gas cannot open the duckbill valve 203, which can achieve closed isolation of the abdominal incision 3, and re-endoscopic exploration or subsequent surgery. In the reverse buckle method, the flow direction of the duckbill valve 203 is from inside to outside, and the intra-abdominal gas can push open the duckbill valve 203 to exhaust when the intra-abdominal pressure is too high, while preventing external gas from entering the patient's body. Medical staff can buckle the cover body forward or backward as needed (install the duckbill valve 203 of the closure cap 2 on the elastic sleeve 1 with the buckle facing toward or away from the elastic sleeve 1) to achieve temporary sealing of the abdominal incision, ensure the airtightness of the incision for endoscope insertion during re-exploration, and discharge the internal gas of the abdomen. It is convenient for medical staff to use, has excellent practicality and safety, improves the efficiency of medical staff, and reduces the burden on medical staff.

[0035] Working principle:

[0036] When the abdominal cavity needs to be sealed, a positive buckle connection method is adopted, that is, the sealing cover plate 201 of the sealing cap 2 is first detachably connected to the rigid connection ring 102 of the elastic sleeve 1 through the first connecting piece, at this time, the sealing cover plate 201 will cover the second opening of the elastic sleeve 1, the exhaust port 202 and the second opening are correspondingly connected, and then the end of the elastic sleeve 1 with the elastic anti-drop ring 101 is inserted into the abdominal incision 3, and the end of the elastic sleeve 1 with the rigid connection ring 102 and the sealing cap 2 are left outside the abdominal incision 3. At this time, the flow direction of the duckbill valve 203 is from the outside to the inside of the abdominal incision 3, and the gas in the abdominal incision 3 cannot open the duckbill valve 203, that is, the two one-way valves of the duckbill valve 203 are in a closed state, and isolation is achieved. In addition, the two one-way valves of the duckbill valve 203 are inclined surfaces, and the greater the pneumoperitoneum pressure, the greater the pressure on the one-way valve toward the middle, so that the closing force at the opening of the one-way valve is greater, and the air tightness will not be affected by the pressure in the pneumoperitoneum, ensuring the pneumoperitoneum environment. When it is necessary to re-insert the endoscope for exploration or the medical device 4 for surgery, the medical staff can directly reach in through the operating exhaust port 202 on the closed cover 201 through the two one-way valves of the duckbill valve 203, and the two one-way valves of the duckbill valve 203 can well wrap the outer edge of the endoscope or the surrounding wall of the medical device 4 to ensure that when the medical staff performs endoscope exploration or surgery, the duckbill valve 203 can also prevent the leakage of abdominal gas, ensure the pneumoperitoneum environment, and improve the exploration effect of the medical staff.

[0037] When it is necessary to vent the abdominal cavity, the reverse connection method is adopted, that is, the first connecting piece is removed from the rigid connecting ring 102, and then the second connecting piece is connected to the rigid connecting ring 102 located outside the abdominal incision 3. At this time, the closed cover 201 will cover the second opening of the elastic sleeve 1, and the operating exhaust port 202 is correspondingly connected to the second opening. At this time, the flow direction of the duckbill valve 203 is from the inside to the outside of the abdominal incision 3. After the gas in the abdominal incision 3 enters the elastic sleeve 1 from the first opening, it will enter the duckbill valve 203 from the second opening and the operating exhaust port 202 in turn. The duckbill valve 203 is automatically opened by the gas pressure, that is, the two one-way valves of the duckbill valve 203 are in an open state to exhaust gas while preventing external gas from entering the patient's body.

[0038] Further, in this embodiment, if Figures 1 to 13 As shown, the inner wall of the duckbill outlet of the duckbill valve 203 is provided with a silicone soft layer 204, that is, the two one-way valve closures of the duckbill valve 203 are provided with a silicone soft layer 204, so that when the medical staff needs to insert the endoscope for exploration again, the silicone soft layer 204 can well wrap the outer edge of the endoscope to prevent the leakage of intra-abdominal gas and ensure the pneumoperitoneum environment. The silicone soft layer 204 is made of medical grade silicone, and its texture is softer than that of the duckbill valve 203. The duckbill valve 203 is made of medical grade rubber, and its texture should not be too soft.

[0039] In this embodiment, a threaded connection method is provided between the first connecting member and the rigid connecting ring 102, such as Figures 1 to 13 As shown, the first connecting member includes a first connecting ring 205, and a first thread 206 is provided on the inner ring wall of the first connecting ring 205. A second thread 103 is provided on the outer ring wall of the rigid connecting ring 102. The second thread 103 matches the first thread 206 to achieve threaded connection between the first connecting ring 205 and the rigid connecting ring 102. After the first thread 206 of the first connecting ring 205 is screwed to the bottom, the first connecting ring 205 will be buckled on the rigid connecting ring 102, and the closing cover plate 201 will cover the inner ring of the rigid connecting ring 102 to close the second opening of the elastic sleeve 1, refer to Figure 1 shown.

[0040] In this embodiment, the second connecting member and the rigid connecting ring 102 are connected by threading. Figures 1 to 13 As shown, the second connecting member includes a second connecting ring 207, and a third thread 208 is provided on the outer ring wall of the second connecting ring 207. A connecting ring groove 104 is provided on the end surface of the rigid connecting ring 102 for the second connecting ring 207 to be inserted. A fourth thread 105 is provided on the side wall of the connecting ring groove 104, and the fourth thread 105 is located inside the connecting ring groove 104. The fourth thread 105 matches the third thread 208 to thread the second connecting ring 207 into the connecting ring groove 104. The third thread 208 of the second connecting ring 207 is screwed to the bottom, and the closing cover plate 201 will cover the inner ring of the rigid connecting ring 102 to close the second opening of the elastic sleeve 1, referring to FIG. Figure 2 shown.

[0041] In this embodiment, a buckling connection method between the first connecting member and the rigid connecting ring 102 is provided. Figures 1 to 13 As shown, the first connecting member includes a first connecting ring 205, and a first annular buckle 209 is provided on the inner ring wall of the first connecting ring 205. A second annular buckle 106 is provided on the outer ring wall of the rigid connecting ring 102, and the second annular buckle 106 is located on the buckling path of the first annular buckle 209. The first connecting ring 205 is buckled on the rigid connecting ring 102. Since the second annular buckle 106 is located below the first annular buckle 209, the second annular buckle 106 will block the first annular buckle 209 from moving further downward. The closed cover plate 201 is pressed downward with force, and the second annular buckle 106 is buckled under the first annular buckle 209. The first connecting ring 205 does not need to be pulled out with force, and the first connecting ring 205 and the rigid connecting ring 102 will not be separated. For reference, Figure 8 and Fig.13Preferably, the second annular buckle 106 is close to the bottom of the rigid connection ring 102 (the end of the rigid connection ring 102 facing the elastic anti-slip ring 101), and the first annular buckle 209 is located at the bottom of the first connection ring 205 (the end away from the closed cover plate 201). When the first annular buckle 209 is located below the second annular buckle 106 and fits, the closed cover plate 201 just fits with the top end surface of the rigid connection ring 102 (the end of the rigid connection ring 102 away from the elastic anti-slip ring 101), so that no shaking occurs between the closed cap 2 and the elastic sleeve 1.

[0042] In this embodiment, a buckling connection method between the second connecting member and the rigid connecting ring 102 is provided. Figures 1 to 13 As shown, the second connecting member includes a second connecting ring 207, and a third ring buckle 210 is provided on the outer ring wall of the second connecting ring 207. A connecting ring groove 104 is provided on the end surface of the rigid connecting ring 102 for the second connecting ring 207 to be inserted into. A fourth ring buckle 107 is provided on the side wall of the connecting ring groove 104, and the fourth ring buckle 107 is located on the buckling path of the third ring buckle 210. The second connecting ring 207 is inserted into the connecting ring groove 104, and the third ring buckle 210 is located above the fourth ring buckle 107. The third ring buckle 210 will be blocked by the fourth ring buckle 107. Press down the closed cover plate 201 with force, and the third ring buckle 210 will buckle under the fourth ring buckle 107. The second connecting ring 207 does not need to be pulled out with force, and the second connecting ring 207 and the connecting ring groove 104 will not be separated. Refer to Figure 7 and Fig.12 shown.

[0043] Further, in this embodiment, if Figures 1 to 13 As shown, when the first connector and the rigid connecting ring 102 are connected by thread, the second connector and the rigid connecting ring 102 can be connected by thread or by snap-fit ​​connection. When the first connector and the rigid connecting ring 102 are connected by snap-fit ​​connection, the second connector and the rigid connecting ring 102 can be connected by thread or by snap-fit ​​connection. The entire closure cap 2 (including the closure cover plate 201, the first connecting ring 205, the first thread 206, the second connecting ring 207, the first annular buckle 209, and the third annular buckle 210) is made of medical grade plastic material, or made of medical grade rubber material with a relatively hard texture.

[0044] Further, in this embodiment, if Figures 1 to 13 As shown, the diameter of the elastic sleeve 1 gradually decreases from both ends to the middle so as to be inserted into the abdominal incision 3. The smaller diameter part in the middle flows into and is stuck in the abdominal incision 3. For details, refer to Figure 6 shown.

[0045] Further, in this embodiment, if Figures 1 to 13As shown, the outer ring wall of the elastic anti-slip ring 101 is an arc-shaped wall, which can avoid damage to the interior of the abdominal cavity.

[0046] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
