Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical tools, and in particular to an auxiliary suturing device for hollow organs. Background Art
[0002] In the traditional enteroenterostomy technique, the assistant lifts the ipsilateral intestinal wall to be sutured, and the surgeon sutures it. Since the intestinal wall is very soft and can overlap and fit each other, it is not easy to form a space for the surgeon to suture. During the suturing process, the needle may damage the intestinal wall on the opposite side, and in severe cases, it may even suture the intestinal wall on the opposite side. Damage or suturing of the intestinal wall on the opposite side may lead to serious consequences such as postoperative intestinal infection, intestinal fistula, intestinal obstruction, etc. In order to avoid damage or suturing of the intestinal wall on the opposite side, the surgeon needs to be extra careful in operation, which significantly reduces efficiency and prolongs the operation time, which is not good for both the surgeon and the patient.
[0003] In recent years, intestinal anastomosis devices made of alloys have appeared, but they are expensive and impose a heavy economic burden on patients and the country. Summary of the invention
[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides an auxiliary suturing device for hollow organs to reduce costs and improve the suturing efficiency and accuracy of the operator.
[0005] According to an embodiment of the present invention, an auxiliary suturing device for hollow organs includes: a main blade, on which a sleeve is provided; a flip blade, which is connected to one side of the main blade and can pivot between a folded position in contact with the main blade and an expanded position parallel to the main blade; a folding drive structure, which is provided at the connection between the main blade and the flip blade and can drive the flip blade to rotate toward the folded position; a pulling structure, which is used to drive the flip blade to rotate toward the expanded position, and the pulling structure includes a connecting rod and a connecting line, which is provided in the sleeve and can reciprocate along the axial direction of the sleeve, and the connecting line is connected to the main blade and the flip blade in sequence and is connected to the connecting rod after being folded back.
[0006] According to the auxiliary suturing device for hollow organs of the embodiment of the present invention, the folding drive structure drives the flip blade to rotate toward the folded position so that the flip blade fits with the main blade, which can reduce the space occupied by the auxiliary suturing device, thereby facilitating the placement of the auxiliary suturing device before suturing and the removal after suturing. When the connecting rod moves in the direction of tightening the connection line, the connection line is forced to pull the flip blade to rotate toward the unfolded position, so that the main blade and the flip blade can play a blocking role during suturing, which can effectively protect the rear organs and significantly improve the suturing efficiency and accuracy of the operator, such as reducing the complexity of the operation, reducing the difficulty of suturing, and reducing the hidden dangers of suturing the organs to be sutured and the rear organs together. In addition, the auxiliary suturing device has a simple structure, low cost, and a wide range of applications, such as being applicable to the intestinal wall, liver surgery bile duct, portal vein and bladder.
[0007] In some embodiments, the sleeve is disposed in the middle of the main blade and both ends of the sleeve are respectively disposed beyond both ends of the main blade, and the connecting rod is disposed beyond the end of the sleeve.
[0008] Specifically, a gripping portion is provided at the end of the connecting rod, and a size of the gripping portion is larger than an inner diameter of the sleeve.
[0009] Furthermore, the connecting rod is provided with a barb structure, and the barb structure can cooperate with the end of the sleeve to limit the freedom of movement of the connecting rod.
[0010] In some embodiments, the auxiliary suturing device for hollow organs further comprises a soft sheath, wherein the soft sheath is disposed at both ends of the main blade and the flip blade, and the connecting line is contained in the soft sheath.
[0011] In some embodiments, a first connecting ring is provided at the end of the main blade, and a second connecting ring is provided at the end of the flip blade. The connecting line is sequentially connected to the first connecting ring, passes through the second connecting ring, folds back and passes through the sleeve and then connected to the connecting rod. When the connecting rod moves toward the axial inner side of the sleeve, the folding drive structure drives the flip blade to pivot toward the folded position; when the connecting rod moves toward the axial outer side of the sleeve, the connecting rod drives the connecting line to drive the flip blade to pivot toward the deployed position.
[0012] In some embodiments, the pulling structure includes two pulling structures, and the two pulling structures are respectively arranged adjacent to two ends of the sleeve.
[0013] In some embodiments, the flip blades include two, and the two flip blades are respectively connected to the two sides of the main blade. When the two flip blades are in the folded position, they are respectively in contact with the two relative main planes of the main blade; the folding drive structure includes two groups and the two groups of folding drive structures are respectively arranged at the connection between the two flip blades and the main blade; the pulling structure is connected to the two flip blades at the same time.
[0014] In some optional embodiments, each group of the folding drive structures includes a plurality of structures that are spaced apart from each other; and the folding drive structures are elastic structures.
[0015] In some embodiments, the length of the flip blade is equal to the length of the main blade, and the width of the flip blade is not greater than the width of the main blade.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0031] Reference below Figure 1-Figure 3 An auxiliary suturing device for a hollow organ according to an embodiment of the present invention is described.
[0032] According to an embodiment of the present invention, an auxiliary suturing device 100 for a hollow organ is provided. Figure 1 As shown, it includes: a main blade 1, a flip blade 2, a folding drive structure 3 and a pulling structure 4. A sleeve 11 is provided on the main blade 1. Figure 2 As shown, the flip blade 2 is connected to one side of the main blade 1, and the flip blade 2 can pivot between a folded position in contact with the main blade 1 and an unfolded position side by side with the main blade 1. The folding drive structure 3 is provided at the connection between the main blade 1 and the flip blade 2, and the folding drive structure 3 can drive the flip blade 2 to rotate toward the folded position. The pulling structure 4 is used to drive the flip blade 2 to rotate toward the unfolded position. The pulling structure 4 includes a connecting rod 41 and a connecting line 42. The connecting rod 41 is provided in the sleeve 11 and can reciprocate along the axial direction of the sleeve 11. The connecting line 42 is connected to the main blade 1 and the flip blade 2 in sequence and is connected to the connecting rod 41 after being folded back.
[0033] It is understandable that the folding drive structure 3 can drive the flip blade 2 to rotate toward the folded position so that the flip blade 2 fits with the main blade 1, which can reduce the space occupied by the auxiliary suturing device 100, so that the auxiliary suturing device 100 can be conveniently placed behind the hollow organ that needs to be sutured. When the connecting rod 41 moves in the direction of tightening the connecting line 42, the connecting line 42 is subjected to force to pull the flip blade 2 to rotate toward the unfolded position until the flip blade 2 and the main blade 1 reach a balance of force at the same horizontal plane. When the surgeon sutures, the damage to the contralateral hollow organ can be reduced due to the barrier effect of the main blade 1 and the flip blade 2. Here, taking the intestinal wall suture as an example, when the intestinal wall is sutured to the middle and late stages, since a part of the intestinal wall at the end has been sutured, the surgeon cannot observe the tortuous intestinal wall at the back. The surgeon sutures based on experience and feeling, and the risk of damaging the posterior intestinal wall is high. Due to the presence of the auxiliary suturing device 100, the operator can sew close to the main blade 1 and the flip blade 2, which can greatly reduce the complexity of the operation and the difficulty of suturing, thereby significantly improving the suturing efficiency, and also greatly improving the accuracy and safety of suturing, and reducing the hidden dangers of suturing the organs to be sutured together with the rear organs. When suturing to the last stitch, the connecting rod 41 moves in the direction of the relaxation line 42. After losing the external force traction, the folding drive structure 3 can drive the flip blade 2 to rotate toward the folded position, and then the reduced auxiliary suturing device 100 is taken out through the unsutured gap. After taking out the auxiliary suturing device 100, the last stitch is sutured again, and then the suturing of the intestinal wall is completed, which significantly reduces the damage to the rear intestinal wall. Of course, when suturing, at least one stitch needs to be reserved to provide a space for taking out the auxiliary suturing device 100, and there is no limit on the number of reserved stitches.
[0034] Here, the connecting rod 41 can be configured to tighten the connecting wire 42 when moving toward the axial outer side of the sleeve 11, and loosen the connecting wire 42 when moving toward the axial inner side of the sleeve 11. The connecting rod 41 can also be configured to pull the connecting wire 42 when moving toward the axial inner side of the sleeve 11, and loosen the connecting wire 42 when moving toward the axial outer side of the sleeve 11. Both can achieve tightening and loosening of the connecting wire 42, and the specific forms of the connecting rod 41, the connecting wire 42 and the sleeve 11 are not limited here.
[0035] In addition, the auxiliary suturing device 100 in the embodiment of the present invention has a simple structure, low cost, and a wide range of applications. For example, it can be applied not only to the intestinal wall, but also to hollow organs such as the liver surgery bile duct, portal vein, and bladder.
[0036] According to the auxiliary suturing device 100 for hollow organs of the embodiment of the present invention, the folding driving structure 3 drives the flip blade 2 to rotate toward the folded position so that the flip blade 2 fits with the main blade 1, which can reduce the occupied space of the auxiliary suturing device 100, thereby facilitating the placement of the auxiliary suturing device 100 before suturing and the removal after suturing. When the connecting rod 41 moves in the direction of tightening the connecting line 42, the connecting line 42 is forced to pull the flip blade 2 to rotate toward the unfolded position, so that the main blade 1 and the flip blade 2 can play a blocking role in suturing, which can effectively protect the rear organs and significantly improve the suturing efficiency and accuracy of the operator, such as reducing the complexity of the operation, reducing the difficulty of suturing, and reducing the hidden dangers of suturing the organs to be sutured and the rear organs together. In addition, the auxiliary suturing device 100 has a simple structure, low cost, and a wide range of applications, such as being applicable to the intestinal wall, liver surgery bile duct, portal vein and bladder.
[0037] In some embodiments, Figure 1 As shown, the sleeve 11 is arranged in the middle of the main blade 1 and the two ends of the sleeve 11 are respectively arranged beyond the two ends of the main blade 1, and the connecting rod 41 is arranged beyond the end of the sleeve 11. This can facilitate the operation of the connecting rod 41 and improve the convenience of the operator. If the connecting rod 41 is exposed outside the sleeve 11, it is convenient to control the folding and unfolding state and direction of the auxiliary suturing device 100.
[0038] Specifically, Figure 1 As shown, a gripping portion 411 is provided at the end of the connecting rod 41, and the size of the gripping portion 411 is larger than the inner diameter of the sleeve 11. In this way, the gripping portion 411 can limit the connecting rod 41, improve the movement stability of the connecting rod 41, and reduce the hidden danger of the connecting rod 41 falling back into the sleeve 11. In addition, the gripping portion 411 can further improve the convenience of the operator's operation.
[0039] Furthermore, if Figure 1 As shown, the connecting rod 41 is provided with a barb structure 412, which can cooperate with the end of the sleeve 11 to limit the freedom of movement of the connecting rod 41. In this way, the barb structure 412 can play a role of limiting and fixing, and can also play a role of continuous traction, so that the flip blade 2 is in a stable unfolded state during the suturing process.
[0040] In some embodiments, Figure 1 As shown, the auxiliary suturing device 100 for hollow organs further includes a soft sheath 5, which is arranged at both ends of the main blade 1 and the flip blade 2, and the connecting line 42 is contained in the soft sheath 5. In this way, the soft sheath 5 can play a good protective role on the hollow organ, reducing the hidden danger of the exposed connecting line 42 causing cutting of the hollow organ.
[0041] Optional, such as Figure 1As shown, the soft sheath 5 is connected to the side of the sleeve 11 and to both ends of the main blade 1 and the flip blade 2. This can improve the connection reliability of the soft sheath 5.
[0042] In some embodiments, Figure 1 As shown, the end of the main blade 1 is provided with a first connecting ring 12, and the end of the flip blade 2 is provided with a second connecting ring 21. The connecting line 42 is sequentially connected to the first connecting ring 12, passes through the second connecting ring 21, folds back and passes through the sleeve 11, and then is connected to the connecting rod 41. When the connecting rod 41 moves toward the axial inner side of the sleeve 11, the folding drive structure 3 drives the flip blade 2 to pivot toward the folded position. When the connecting rod 41 moves toward the axial outer side of the sleeve 11, the connecting rod 41 drives the connecting line 42 to drive the flip blade 2 to pivot toward the deployed position. It can be understood that when the connecting rod 41 moves toward the axial outer side of the sleeve 11, the connecting line 42 can be tightened, and the connecting line 42 is subjected to force to pull the flip blade 2, so that the flip blade 2 pivots toward the deployed position. When the connecting rod 41 moves toward the axial inner side of the sleeve 11, the connecting line 42 is loosened. When the connecting rod 41 moves toward the axial inner side of the sleeve 11, the connecting line 42 can be loosened, and the folding drive structure 3 drives the flip blade 2 to pivot toward the folded position. This makes it easier to operate the connecting rod 41. In addition, the first connecting ring 12 and the second connecting ring 21 can guide the movement of the connecting line 42, thereby improving the operating stability of the connecting line 42.
[0043] Optional, such as Figure 3 As shown, the sleeve is provided with a through hole 111, and the connecting line 42 passes through the through hole 111 and is connected to the connecting rod 41. It should be noted here that the through hole 111 can be a round hole, an elliptical hole, etc., which can effectively allow the connecting line 42 to pass through, and the specific form of the through hole 111 is not limited here.
[0044] In some embodiments, Figure 1 As shown, the pulling structure 4 includes two, and the two pulling structures 4 are respectively arranged adjacent to the two ends of the sleeve 11. This can facilitate the operation of the pulling structure 4, and the direction adjustment step of the auxiliary suturing device 100 can be omitted. That is, in the suturing direction of the hollow organ, the auxiliary suturing device 100 does not need to be divided into directions. Of course, in some other embodiments, the pulling structure 4 can also be one, and the pulling structure 4 is arranged adjacent to one end of the sleeve 11. At this time, the traction structure should be placed toward the end of the suturing direction to facilitate the removal operation after the suturing is completed. The above can also realize the driving function of the traction structure, and the specific setting form of the traction structure is not limited here.
[0045] In some embodiments, Figure 1 and Figure 2As shown, the flip blades 2 include two, and the two flip blades 2 are respectively connected to the two sides of the main blade 1. When the two flip blades 2 are in the folded position, they are respectively in contact with the two opposite main planes of the main blade 1. This is conducive to reducing the space occupied by the auxiliary suturing device 100 and facilitating the insertion and removal of the auxiliary suturing device 100. The folding drive structure 3 includes two groups, and the two groups of folding drive structures 3 are respectively arranged at the connection between the two flip blades 2 and the main blade 1. The pulling structure 4 is connected to the two flip blades 2 at the same time. In this way, during the folding process, the flipping directions of the two flip blades 2 are opposite, and the two flip blades 2 can be effectively acted on by the setting of the two groups of folding drive devices. In addition, the pulling structure 4 can simplify the structure of the auxiliary suturing device 100 by acting on the movement of the two flip blades 2 at the same time.
[0046] In some optional embodiments, such as Figure 1 As shown, each group of folding drive structures 3 includes a plurality of folding drive structures 3 that are spaced apart from each other, and the folding drive structures 3 are elastic structures. This is conducive to improving the operating stability of the folding drive device. In addition, the folding drive device is set as an elastic structure, which is conducive to the repeatability of the folding operation.
[0047] In some embodiments, Figure 1 As shown, the length of the flip blade 2 is equal to the length of the main blade 1, and the width of the flip blade 2 is not greater than the width of the main blade 1. This is conducive to improving the structural strength of the auxiliary suturing device 100 and improving the rotation stability of the flip blade 2.
[0048] Optionally, when the hollow organ is the intestinal wall, the width of the main blade 1 is about 0.5 cm, the width of the flip blade 2 is slightly smaller than the main blade 1, and the total width of the unfolded auxiliary suturing device 100 is slightly less than 1.5 cm. Because the needle distance when suturing the intestinal wall is clinically about 0.3-0.4 cm, this width is sufficient to meet the need to protect the intestinal tube when suturing the intestinal wall.
