Description

Technical Field

[0001] This application relates to the technical field of medical devices, and particularly to a tissue suture system. Background Art

[0002] Suturing is to align or reconstruct the channels of tissues and organs that have been incised or traumatized and broken, and restore their functions. It is a basic condition for ensuring good healing and one of the important basic surgical operation techniques. Different tissues and organs in different parts need to be sutured in different ways.

[0003] The existing Chinese patent with the reference publication number CN113855126A discloses a continuously usable forceps-type deep tissue suture instrument, which includes a first forceps body and a second forceps body. Clamping structures for clamping suture needles are symmetrically arranged on the first forceps body and the second forceps body; the clamping structures include: a first clamping structure and a second clamping structure capable of self-locking are arranged on the first forceps body and the second forceps body, and the clamping states of the first clamping structure and the second clamping structure are opposite during use. The position replacement of the suture needle between the first clamping structure and the second clamping structure is realized through the mutual cooperation of the two clamping structures; during use, first press and fix the suture needle in the first clamping structure or the second clamping structure, and then bring the front ends of the first forceps body and the second forceps body closer and merge. At the same time, the first forceps body or the second forceps body will release the clamping, and the corresponding first forceps body or the second forceps body will clamp the suture needle.

[0004] In view of the above related technologies, due to the different depths and penetration directions of different wounds, the angles during suturing are also different. When the user sutures wounds at some tricky angles, restricted by the postures of the fingers and wrists, it is easy to result in poor suture effects. Summary of the Invention

[0005] In order to enable the user to suture wounds at various angles more conveniently and comfortably and improve the suture effect, this application provides a tissue suture system.

[0006] The tissue suture system provided by this application adopts the following technical solutions:

[0007] A tissue suture system includes two hinged forceps bodies. Rings for the user's fingers to penetrate are connected to one ends of the two forceps bodies in the same orientation. The ends of the forceps bodies away from the rings are suture ends. Two oppositely arranged connecting plates are fixed to the side of each ring facing the corresponding forceps body. A rotating shaft is installed at the end of the forceps body close to the ring. Both connecting plates are rotatably connected to the rotating shaft. An adjusting and fixing component for fixing the connecting plates at a specified angle is provided between the connecting plates and the rotating shaft.

[0008] By adopting the above technical solution, before tissue suture, the user can judge the wound depth, the penetration direction and the angle during suture. After adjusting the fixing component to rotate the finger ring to a suitable angle, the connecting plate and the pliers body are fixed, so that the finger ring is fixed to a convenient operation angle, achieving the effect of enabling the user to suture wounds at various angles more conveniently and comfortably, thereby improving the suture effect.

[0009] Optionally, a perforation for the rotation shaft to pass through is provided on the pliers body. The rotation shaft is slidably connected to the pliers body, and the sliding direction of the rotation shaft is consistent with its own axis direction; the adjustment and fixing component includes a pressing plate, an adjustment spring and a positioning block. Both ends of the rotation shaft protrude from the corresponding connecting plate. The pressing plate is fixed at one end of the rotation shaft, and the adjustment spring is fixed on the pressing plate and contacts the connecting plate; a through hole for the rotation shaft to pass through is provided on the connecting plate, and a plurality of positioning holes are equidistantly arranged on the inner peripheral surface of the through hole around its own axis. The positioning block is fixed on the rotation shaft and is used for inserting into the positioning holes.

[0010] By adopting the above technical solution, when the angle between the finger ring and the pliers body needs to be adjusted, the pressing plate is pushed to compress the adjustment spring, and at the same time the positioning block disengages from the positioning hole. At this time, the finger ring can be rotated until the positioning block is aligned with the specified positioning hole, then the pressing plate is released, and the adjustment spring drives the rotation shaft to slide back to its original position, so that the positioning block is inserted into the positioning hole again, and the angle of the finger ring can be fixed; by inserting the positioning block into different positioning holes, multi-angle adjustment of the finger ring is realized, and the operation is convenient and efficient.

[0011] Optionally, the adjustment spring is sleeved on the rotation shaft, and an annular plate sleeved on the rotation shaft is fixed at one end of the adjustment spring away from the pressing plate, and the annular plate is attached to the connecting plate.

[0012] By adopting the above technical solution, the adjustment spring can increase the contact area with the connecting plate in a variable direction through the annular plate, and avoid the adjustment spring entering the positioning hole, improving the operation stability.

[0013] Optionally, a plurality of guiding blocks are equidistantly fixed on the inner side wall of the connecting plate where the positioning holes are opened around the axis of the through hole. The end of the guiding block away from the connecting plate is provided with a sharp edge, and the two side edges of the guiding block on the connecting plate coincide with the adjacent side edges of the adjacent two positioning holes.

[0014] By adopting the above technical solution, after the pressing plate is pushed to make the positioning block disengage from the positioning hole, the pressing plate is continuously pushed to make the positioning block disengage between the adjacent guiding blocks. When the finger ring is rotated, the guiding block rotates accordingly. When the pressing plate is released, due to the sharp edge of the guiding block, the inclined surfaces on both sides of the guiding block can guide the positioning block, improving the accuracy and stability of the positioning block entering the specified positioning hole.

[0015] Optionally, a guide tube coaxial with the rotating shaft is fixed to the outer side wall of the connecting plate without the positioning hole. A threaded tube is fitted to the inner peripheral surface of the guide tube, and the end of the rotating shaft is threadedly connected to the threaded tube.

[0016] By adopting the above technical solution, when the pressing plate is pushed to slide the rotating shaft, the end of the rotating shaft drives the threaded tube to slide in the guide tube, improving the sliding stability of the rotating shaft. And the setting of the threaded tube can prevent the rotating shaft from detaching from the connecting plate and the pliers body; after unscrewing the threaded tube, the rotating shaft can be directly pulled out, facilitating the replacement of the pliers body or the finger ring, reducing the cost, and the finger ring that is more suitable can be replaced according to the width of the user's finger, improving the suture effect.

[0017] Optionally, a return spring is fixed between the end surface of the threaded tube located in the guide tube and the connecting plate.

[0018] By adopting the above technical solution, the return spring can cooperate with the adjusting spring to improve the return efficiency of the rotating shaft.

[0019] Optionally, a chute communicating with the through hole is provided on one side of the pliers body facing the positioning hole. A slider that slides in the chute is fixed on the rotating shaft, and the positioning hole allows the slider to pass through.

[0020] By adopting the above technical solution, when the rotating shaft slides, the slider slides in the chute, improving the sliding stability of the rotating shaft.

[0021] Optionally, a limiting shaft perpendicular to the rotating shaft is rotatably connected to the pliers body. A limiting groove is provided on one side of the chute. One end of the limiting shaft is located in the limiting groove, and the other end is located outside the pliers body. A top block that can be turned into the chute is fixed to the end of the limiting shaft located in the chute. A limiting component is provided on the pliers body for driving the limiting shaft to rotate so that the top block abuts against the side of the slider away from the through hole, or driving the limiting shaft to rotate so that the top block completely enters the limiting groove.

[0022] By adopting the above technical solution, when the limiting component drives the limiting shaft to rotate so that the top block abuts against the side of the sliding hole away from the through hole, the slider and the rotating shaft cannot move, which can avoid the phenomenon that the positioning block detaches from the positioning hole due to accidental touch of the pressing plate, improving the stability and safety during suturing; when the angle of the finger ring needs to be adjusted, by driving the limiting shaft to rotate through the limiting component so that the top block is completely located in the limiting groove, the pressing plate can be pushed to slide the rotating shaft.

[0023] Optionally, the limiting component includes a lever, a first limiting rod and a second limiting rod. The lever is fixed to the outer end of the limiting shaft. A part of the lever away from the limiting shaft is made of rubber. The first limiting rod and the second limiting rod are both fixed to the outer surface of the pliers body. When the lever is located on the side of the first limiting rod away from the second limiting rod, the top block abuts against the side of the slider away from the through hole; when the lever is located on the side of the second limiting rod away from the first limiting rod, the top block is completely located in the limiting groove.

[0024] By adopting the above technical solution, rotating the lever and moving it to one side of the first limiting rod or the second limiting rod can enable the limiting shaft to drive the top block to rotate until it abuts against the slider or enters the limiting groove. The structure is simple and the operation is convenient, realizing the anti-misoperation function of the pressing plate.

[0025] Optionally, the outer end of the lever, one end of the first limiting rod and one end of the second limiting rod facing the limiting column are all provided with pointed ends.

[0026] By adopting the above technical solution, it is more beneficial for the lever to deform to pass through the first limiting rod or the second limiting rod.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The user can judge the depth, penetration direction and angle during suturing of the wound, and after adjusting the fixing component to rotate the finger ring to a suitable angle, fix the connecting plate and the pliers body, so that the finger ring is fixed to an angle convenient for operation, achieving the effect of enabling the user to suture the wound at various angles more conveniently and comfortably, thereby improving the suturing effect;

[0029] 2. Push the pressing plate to compress the adjusting spring, and at the same time, the positioning block disengages from the positioning hole. At this time, the finger ring can be rotated until the positioning block is aligned with the specified positioning hole, then release the pressing plate, the rotating shaft slides back to its original position, and the positioning block is inserted into the positioning hole again, fixing the angle of the finger ring; by inserting the positioning block into different positioning holes, multi-angle adjustment of the finger ring is realized, and the operation is convenient and efficient;

[0030] 3. Push the pressing plate to make the positioning block disengage between the positioning hole and the adjacent guiding block. When the finger ring is rotated, the guiding block rotates accordingly. When the pressing plate is released, since the guiding block has a sharp edge, the inclined surfaces on both sides of the guiding block can guide the positioning block, improving the accuracy and stability of the positioning block entering the specified positioning hole;

[0031] 4. When the limiting component drives the limiting shaft to rotate so that the top block abuts against the side of the sliding hole far from the through hole, the slider and the rotating shaft cannot move, which can avoid the phenomenon that the pressing plate is misoperated and the positioning block disengages from the positioning hole, improving the stability and safety during suturing.

Specific embodiments

[0037] The following will Figures 1-4 further elaborate on this application in detail with reference to the appended

[0038] The embodiments of this application disclose a tissue suture system.

[0039] Referring to Figure 1 and Figure 2 , the tissue suture system includes two hinged pliers bodies 1. At one end of each pliers body 1 away from its own suture end, a finger ring 2 for the user to insert a finger is installed. On the outer peripheral surface of each finger ring 2, two oppositely arranged connecting plates 3 are fixed. The end of the pliers body 1 is located between the two connecting plates 3, and a rotating shaft 4 is installed at the end of the pliers body 1. The axis of the rotating shaft 4 is perpendicular to the hinge axis of the pliers body 1. The connecting plates 3 are all rotatably connected to the rotating shaft 4, and an adjusting and fixing component 5 for fixing the connecting plates 3 at a specified angle is provided between the connecting plates 3 and the rotating shaft 4. The user can judge the wound depth, the penetration direction, and the angle during suturing, and adjust and fix the angle between the finger ring 2 and the pliers body 1 through the adjusting and fixing component 5, which can enable the user to perform wound suturing at various angles more conveniently and comfortably, so as to improve the suturing effect.

[0040] Referring to Figure 2 and Figure 3 , both ends of the rotating shaft 4 extend out of the corresponding connecting plates 3. A perforation 11 for the rotating shaft 4 to pass through and a chute 12 communicating with the perforation 11 are provided on one side of the pliers body 1. A slider 41 that slides in the chute 12 is fixed on the rotating shaft 4, and the length direction of the chute 12 is parallel to the rotating shaft 4; the adjusting and fixing component 5 includes a pressing plate 51 fixed at one end of the rotating shaft 4, an annular plate 53 sleeved on the rotating shaft 4 and located on the side of the connecting plate 3 facing the pressing plate 51, an adjusting spring 52 sleeved on the rotating shaft 4 and fixed between the pressing plate 51 and the annular plate 53, and a positioning block 54 fixed on the rotating shaft 4; a through hole 31 for the rotating shaft 4 to pass through is provided on the connecting plate 3 close to the pressing plate 51, and a plurality of positioning holes 32 for the positioning block 54 to insert are equidistantly arranged around the axis of the inner peripheral surface of the through hole 31, and the positioning holes 32 can be passed through by the slider 41.

[0041] When adjusting the angle of the finger ring 2, push the pressing plate 51 to make the rotating shaft 4 slide. After the positioning block 54 is separated from the positioning hole 32, rotate the finger ring 2 to adjust the angle. Until the positioning block 54 is aligned with the positioning hole 32 at a suitable position, release the pressing plate 51, and the positioning block 54 is inserted into the positioning hole 32 to complete the fixation after the adjustment of the finger ring 2; by inserting the positioning block 54 into different positioning holes 32, multi-angle adjustment of the finger ring 2 is realized, and the operation is convenient and efficient.

[0042] Reference Figure 3 , several guiding blocks 33 are fixed on the inner side wall of the connecting plate 3 close to the pressing plate 51. The guiding blocks 33 are equidistantly distributed around the axis of the through hole 31, and a single guiding block 33 is located between two adjacent positioning holes 32. The end of the guiding block 33 away from the connecting plate 3 is provided with a sharp edge, and the two side lines of the guiding block 33 in contact with the connecting plate 3 coincide with the side lines of two adjacent positioning holes 32 that are close to each other. After the positioning block 54 is separated from between the positioning hole 32 and the adjacent guiding block 33, then rotate the finger ring 2. When the finger ring 2 finishes rotating and the pressing plate 51 is released, the inclined surface of the guiding block 33 can play a guiding role on the positioning block 54, so that the positioning block 54 can be inserted into the positioning hole 32 more smoothly and accurately, improving the operation stability.

[0043] Reference Figure 2 and Figure 4 , a threaded tube 61 is threadedly connected to one end of the rotating shaft 4 away from the pressing plate 51. A guiding tube 6 is fixed on the outer side wall of the connecting plate 3 away from the pressing plate 51. The outer peripheral surface of the threaded tube 61 fits with the inner peripheral surface of the guiding tube 6; a return spring 62 is fixed between the end surface of the threaded tube 61 located inside the guiding tube 6 and the connecting plate 3. On the one hand, the threaded tube 61 can prevent the rotating shaft 4 from sliding in the opposite direction and detaching from the connecting plate 3 and the pliers body 1. On the other hand, it can cooperate with the guiding tube 6 to improve the sliding stability of the rotating shaft 4. The return spring 62 can cooperate with the adjusting spring 52 to improve the reset efficiency of the rotating shaft 4. And after unscrewing the threaded tube 61, the rotating shaft 4 can be pulled out from the connecting plate 3 and the pliers body 1, which is convenient for replacing the pliers body 1 or the finger ring 2, reducing the cost, and the finger ring 2 that is more suitable can be replaced according to the finger width of the user, improving the suture effect.

[0044] Reference Figure 2 and Figure 4, a limiting groove 13 is formed on one side of the sliding groove 12 away from the perforation 11. One end of the pliers body 1 is rotatably connected to a limiting shaft 7 perpendicular to the rotating shaft 4. One end of the limiting shaft 7 is located in the limiting groove 13, and the other end extends out of the pliers body 1. A top block 71 is fixed to the end of the limiting shaft 7 located in the limiting groove 13. The top block 71 can rotate into the sliding groove 12 and abut against the side of the slider 41 away from the pressing plate 51. A limiting component 8 is provided on the pliers body 1, which can abut the top block 71 against the side of the slider 41 away from the through hole 31 after the limiting shaft 7 rotates, or drive the limiting shaft 7 to rotate and completely turn the top block 71 into the limiting groove 13.

[0045] Reference Figure 4 , the limiting component 8 includes a lever 81 fixed to the outer end of the limiting shaft 7, a first limiting rod 82 and a second limiting rod 83 fixed to the outer surface of the pliers body 1. A part of the lever 81 away from the limiting shaft 7 is made of deformable rubber material. The outer end of the lever 81, the first limiting rod 82 and the end of the second limiting rod 83 facing the limiting column are all provided with pointed ends. When the lever 81 is located on the side of the first limiting rod 82 away from the second limiting rod 83, the top block 71 abuts against the side of the slider 41 away from the through hole 31. When the lever 81 is located on the side of the second limiting rod 83 away from the first limiting rod 82, the top block 71 is completely located in the limiting groove 13.

[0046] When the lever 81 is located on the side of the first limiting rod 82 away from the second limiting rod 83, the slider 41 is restricted by the top block 71 and cannot slide, thereby avoiding the sliding of the rotating shaft 4 caused by accidental touch of the pressing plate 51, and improving the safety and stability during suturing. When the angle of the finger ring 2 needs to be adjusted, first rotate the lever 81 to the side of the second limiting rod 83 away from the first limiting rod 82. At this time, pushing the pressing plate 51 can make the rotating shaft 4 slide smoothly. After the rotating shaft 4 slides and resets, then rotate the lever 81 to the side of the first limiting rod 82 away from the second limiting rod 83 to realize the anti-accidental touch function of the pressing plate 51.

[0047] The implementation principle of an organization suture system in an embodiment of the present application is as follows: when the angle of the finger ring 2 needs to be adjusted, first rotate the lever 81 to the side of the second limiting rod 83 away from the first limiting rod 82, and then push the pressing plate 51 to make the rotating shaft 4 slide. After the positioning block 54 is separated from the positioning hole 32, rotate the finger ring 2 to adjust the angle until the positioning block 54 is aligned with the positioning hole 32 at a suitable position, then release the pressing plate 51, and the positioning block 54 is inserted into the positioning hole 32 to complete the fixation after the adjustment of the finger ring 2. Then rotate the lever 81 to the side of the first limiting rod 82 away from the second limiting rod 83 to realize the anti-accidental touch function of the pressing plate 51. Finally, by adjusting the angle of the finger ring 2, the user can perform wound suturing at various angles more conveniently and comfortably, so as to improve the suturing effect.

[0048] The embodiments of the specific implementation manners are all preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
