Description

Technical Field

[0001] This utility model belongs to the field of medical technology, and in particular relates to an abdominal wall suture device. Background Technology

[0002] An abdominal wall suture device is a medical device used to close incisions after abdominal surgery, especially during abdominal surgery. Its main function is to help surgeons effectively and precisely suture the various layers of abdominal wall tissue (such as skin, fat layer, peritoneum, etc.) together after surgery, promote wound healing, and reduce the risk of infection or postoperative complications.

[0003] When suturing the incision, the two sides of the abdominal wall need to be fixed with a specific clamping device. During the fixation process, the skin itself has a certain tension, which may cause the clamp to loosen, thus affecting the suturing effect and even increasing the risk of postoperative complications. To address this, we provide an abdominal wall suturing device. Utility Model Content

[0004] The purpose of this invention is to provide an abdominal wall suture device that uses a worm gear to drive a bidirectional threaded rod to rotate, thereby causing a rubber rod to clamp the two sides of the abdominal wall. This solves the problem that existing devices may loosen during clamping due to the tension of the skin itself.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an abdominal wall suture device, including a support frame, a fixing mechanism provided on the outer wall of the support frame, and a suture mechanism provided at the bottom of the support frame;

[0007] The fixing mechanism includes a fixing block one, the inner wall of the fixing block one is fixedly connected to the outer wall of the support frame, a bidirectional threaded rod is rotatably connected to the inner wall of the fixing block one, a worm gear is fixedly connected to the outer wall of the bidirectional threaded rod, a worm is rotatably connected to the outer wall of the support frame, a clamping arm is threadedly connected to the outer surface of the bidirectional threaded rod, two clamping arms are provided, a rubber rod is fixedly connected to the side of the two clamping arms that are close to each other, a fixing block two is fixedly connected to the outer wall of the support frame, and a limit rod one is fixedly connected to the inner wall of the fixing block two.

[0008] Furthermore, the outer surface of the bidirectional threaded rod is rotatably connected to the inner wall of the support frame, the worm gear meshes with the worm wheel, the outer wall of the limiting rod is fixedly connected to the inner wall of the support frame, and the outer surface of the limiting rod is slidably connected to the inner wall of the clamping arm.

[0009] Furthermore, the sewing mechanism includes a sliding block, and a sliding groove is provided inside the support frame, with the inner wall of the sliding groove slidably connected to the outer surface of the sliding block.

[0010] Furthermore, an electric telescopic rod is fixedly connected to the bottom of the first sliding block, a guide block is fixedly connected to the bottom of the electric telescopic rod, and a second sliding block is slidably connected to the inner wall of the guide block.

[0011] Furthermore, a fixed shell is fixedly connected to the inner wall of the sliding block two, a suture needle is fixedly connected to the outer wall of the fixed shell, a push rod is slidably connected to the inner wall of the fixed shell, and the outer surface of the push rod is slidably connected to the inner wall of the suture needle.

[0012] Furthermore, a hook is fixedly connected to the outer wall of the push rod, a sliding disc is fixedly connected to the outer surface of the push rod, a compression spring is fixedly connected to the outer wall of the sliding disc, the outer wall of the compression spring is fixedly connected to the inner wall of the fixed shell, and a limit rod is slidably connected inside the sliding disc.

[0013] Furthermore, the outer wall of the limiting rod is fixedly connected to the inner wall of the fixed shell, a telescopic rod is fixedly connected to the inner wall of the sliding disc, a compression spring is fixedly connected to the inner wall of the sliding disc, and an insert block is fixedly connected to the outer wall of the telescopic rod.

[0014] Furthermore, the end of the outer wall of the compression spring away from the sliding disc is fixedly connected to the inner wall of the insertion block, and the fixed shell has an insertion hole inside, with a total of several insertion holes. The outer surface of the insertion block is slidably connected to the inner wall of the insertion hole.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model, by setting a rubber rod, allows for the following steps when suturing an incision: First, the two sides of the incision are pinched together. Then, the center point of the fixing mechanism is placed on top of the incision, and the rubber rod is pressed against the skin on both sides of the incision. The worm gear is then rotated, causing the worm wheel to rotate. The worm wheel then rotates the bidirectional threaded rod, which in turn moves the clamping arms on both sides towards the sides of the incision. Simultaneously, the clamping arm on the other side slides within the limiting rod. The clamping arm then moves the rubber rod until the worm gear precisely clamps both sides of the abdominal wall. This ensures even force on both sides of the incision and a secure fixation, facilitating subsequent suturing operations and effectively improving the stability and accuracy of the suturing process.

[0017] 2. This utility model, by setting a suture needle, allows the sliding block one to slide in the sliding groove after the incision surface is fixed, pushing it to the starting point of the incision. Then, the electric telescopic rod is activated, which drives the suture needle at the bottom to adjust up and down until it aligns with the incision. At this point, the two insert blocks on both sides can be squeezed, causing them to compress the internal compression spring two. Simultaneously, the telescopic rod acts as a limit. Then, the push rod is pushed, causing the sliding plate to slide within the fixed shell. The sliding plate also slides on the surface of the limit rod two. When the two insert blocks contact the insertion hole on the left side of the sliding block two, the compression spring two causes the two insert blocks to reset, and the insert blocks become locked inside the insertion hole. The push rod then causes the external thread hook to disengage from the suture needle. The suture thread can then be placed inside the thread hook. Finally, the insert block is pressed again. The push rod is then pulled back to its original position. At this point, the insertion block will be locked inside the insertion hole on the right side of the sliding block two. The suture hook will also be driven back to its original position by the push rod and will be inside the suture needle. Suturing can then be performed. The medical staff can push the sliding block two to insert the suture needle into the incision, passing through the skin on both sides. The push rod can then be pushed again, causing the suture hook to pull the suture thread away from inside the suture needle. The medical staff can then adjust the tightness of the suture thread, and then put it back into the suture hook and pull the push rod back to its original position. After suturing one section, the sliding block one can be pushed along the suturing direction to move the suture needle. This process can be repeated to complete the suturing, ensuring that each step is closely connected and guaranteeing the precision and stability of the suturing operation. This precise operating procedure not only improves suturing efficiency but also greatly reduces the possibility of errors during the operation, ensuring the safety and recovery effect of the patient.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 As shown, this utility model is an abdominal wall suture device, including a support frame 3, a fixing mechanism 1 is provided on the outer wall of the support frame 3, and a suture mechanism 2 is provided at the bottom of the support frame 3;

[0029] The fixing mechanism 1 includes a fixing block 102, the inner wall of which is fixedly connected to the outer wall of the support frame 3. A bidirectional threaded rod 101 is rotatably connected to the inner wall of the fixing block 102. The bidirectional threaded rod 101 can drive the clamping arms 103 on both sides to move, thereby driving the rubber rods 104 fixed at their bottom to move. This causes the rubber rods 104 on both sides to gradually move closer to the incision until they clamp the skin on both sides of the abdominal wall, thus ensuring appropriate tension on both sides of the incision. This ensures that the skin is smoothly joined during suturing, preventing the skin from loosening during suturing, thereby improving the suturing effect and promoting rapid wound healing after surgery. A worm gear 106 is fixedly connected to the outer wall of the bidirectional threaded rod 101, and a worm 107 is rotatably connected to the outer wall of the support frame 3. The worm 107 can drive the worm gear 106 to rotate, thereby driving the bidirectional threaded rod 101 to rotate. The worm gear 106 and the worm 107 work together to achieve self-locking, thus greatly improving the accuracy of the equipment and effectively preventing the skin from being too loose or too tight. The outer surface of the bidirectional threaded rod 101 is threaded with clamping arms 103. Two clamping arms 103 are provided. A rubber rod 104 is fixedly connected to one side of the two clamping arms 103 that is close to each other. The rubber rod 104 enhances the friction with the skin, making it less prone to slipping and effectively protecting the skin from injury. A fixing block 2 108 is fixedly connected to the outer wall of the support frame 3. A limiting rod 105 is fixedly connected to the inner wall of the fixing block 2 108. The limiting rod 105 allows the two sides to... The clamping arm 103 is more stable during movement, further improving the accuracy of adjustment. The outer surface of the bidirectional threaded rod 101 is rotatably connected to the inner wall of the support frame 3. The worm 107 meshes with the worm wheel 106. The outer wall of the limiting rod 105 is fixedly connected to the inner wall of the support frame 3. The outer surface of the limiting rod 105 is slidably connected to the inner wall of the clamping arm 103. The sewing mechanism 2 includes a sliding block 202. The support frame 3 has a sliding groove 201 inside. The inner wall of the sliding groove 201 is slidably connected to the outer surface of the sliding block 202.

[0030] A sliding block 202 is fixedly connected to an electric telescopic rod 203 at its bottom. Pushing the sliding block 202 allows it to slide within the sliding groove 201, enabling precise adjustment of the suturing tool's position and angle during suturing. The smoothness of the sliding mechanism also improves suturing speed and reduces surgical time. A guide block 204 is fixedly connected to the bottom of the electric telescopic rod 203. The electric telescopic rod 203 allows for height adjustment of the bottom suturing mechanism 2, ensuring precise alignment of the suture needle 206 with the incision, guaranteeing stability and accuracy during suturing, and reducing operational errors. A second sliding block 205 is slidably connected to the inner wall of the guide block 204. A fixed housing 207 is fixedly connected to the inner wall of the second sliding block 205. A suture needle 206 is fixedly connected to the outer wall of the fixed housing 207. The suture needle 206 drives the suture thread to penetrate the patient's skin, assisting medical personnel in suturing. The inner wall of the fixed housing 207 slides... A push rod 208 is connected to the suture needle 206. Pushing the push rod 208 causes the external suture hook 209 to slide inside the suture needle 206. When the suture hook 209 is outside the suture needle 206, the suture can be hooked onto its surface. Then, pulling the push rod 208 retracts the suture hook 209 and suture into the suture needle 206, thus achieving precise suture insertion and retrieval. This ensures a more efficient and safer suturing process, reducing surgical complications caused by suture entanglement or misalignment. In this case, the outer surface of the push rod 208 is slidably connected to the inner wall of the suture needle 206, the outer wall of the push rod 208 is fixedly connected to the hook 209, the outer surface of the push rod 208 is fixedly connected to the sliding plate 212, the outer wall of the sliding plate 212 is fixedly connected to the compression spring 211, the outer wall of the compression spring 211 is fixedly connected to the inner wall of the fixed shell 207, and the sliding plate 212 is slidably connected to the limit rod 210. The limit rod 210 can limit the sliding plate 212 to make it move horizontally in a straight line.

[0031] The outer wall of the limiting rod 210 is fixedly connected to the inner wall of the fixed shell 207. A telescopic rod 214 is fixedly connected to the inner wall of the sliding disc 212. A compression spring 215 is fixedly connected to the inner wall of the sliding disc 212. An insert block 216 is fixedly connected to the outer wall of the telescopic rod 214. By pressing the insert blocks 216 on both sides, the insert blocks 216 can be compressed. Simultaneously, the insert blocks 216 will drive the compression spring 215 to compress. Subsequently, the insert blocks 216 on both sides will disengage from the fixed shell 207, allowing the push rod 208 to push the suture hook 209 to move, achieving precise delivery and retrieval of the suture thread, ensuring a smoother suturing operation, and reducing... To minimize the possibility of obstruction or error during the suturing process, the outer wall of the compression spring 215, away from the sliding disc 212, is fixedly connected to the inner wall of the insert block 216. The fixed shell 207 has an insertion hole 213 inside. Through the insertion holes 213 distributed on both sides, when the insert block 216 is inserted into the insertion hole 213 on the left side of the sliding block 205, the thread hook 209 will disengage from the suture needle 206. Conversely, when the insert block 216 is inserted into the insertion hole 213 on its right side, the thread hook 209 will return to the suture needle 206. There are several insertion holes 213 in total, and the outer surface of the insert block 216 is slidably connected to the inner wall of the insertion hole 213.

[0032] One specific application of this embodiment is:

[0033] When the incision needs to be sutured, first pinch the two sides of the incision together, then place the center point of the fixing mechanism 1 at the top of the incision, and simultaneously press the rubber rod 104 against the skin on both sides of the incision. Then rotate the worm gear 107, which will drive the worm wheel 106 to rotate. The worm wheel 106 will then drive the bidirectional threaded rod 101 to rotate, and the bidirectional threaded rod 101 will drive the clamping arms 103 on both sides to move closer to the sides of the incision. At the same time, the clamping arm 103 on the other side will slide in the limiting rod 105. Then the clamping arm 103 will drive the rubber rod 104 to move until the worm gear 107 is rotated to accurately clamp the two sides of the abdominal wall. This ensures that the skin on both sides of the incision is evenly stressed, and that the incision is firmly fixed, which facilitates subsequent suturing operations and effectively improves the stability and accuracy of the suturing process.

[0034] Once the incision surface is fixed, slide block 202 can be pushed to slide in sliding groove 201 until it reaches the starting point of the incision. Then, activate electric telescopic rod 203. Electric telescopic rod 203 will then drive the bottom suture needle 206 to adjust up and down until the suture needle 206 is aligned with the incision. At this point, the insert blocks 216 on both sides can be squeezed by hand. The insert blocks 216 will then compress the internal compression spring 215. At the same time, telescopic rod 214 is responsible for limiting the movement. Then, push rod 208 is pushed. This causes the sliding plate 212 to slide within the fixed housing 207, and simultaneously slides on the surface of the limiting rod 210. Then, when the two side inserts 216 contact the insertion hole 213 on the left side of the sliding block 205, the compression spring 215 causes the two side inserts 216 to reset, and the inserts 216 become locked inside the insertion hole 213. Subsequently, the push rod 208 causes its external thread hook 209 to disengage from the suture needle 206. At this point, the suture thread can be placed inside the thread hook 209, and then pressed again. Insert block 216 and pull push rod 208 back to its original position. At this time, insert block 216 will be stuck inside the insertion hole 213 on the right side of sliding block 205. At this time, suture hook 209 will also be driven back to its original position by push rod 208 and will be inside suture needle 206. Suturing can then be performed. Medical personnel can push sliding block 205 to slide inside guide block 204 and drive suture needle 206 to insert into the incision position and pass through the skin on both sides. At this time, push rod 208 can be pushed again, so that suture hook 209 drives the suture to come out from inside suture needle 206. At this point, medical staff can adjust the tightness of the suture, then insert it back into the suture hook 209 and pull the push rod 208 to reset it. After suturing one section, the sliding block 202 can be pushed along the suturing direction to move the suture needle 206. By repeating this process, the suturing can be completed, thus ensuring that each step is closely connected and guaranteeing the precision and stability of the suturing operation. This precise operating procedure not only improves suturing efficiency but also greatly reduces the possibility of errors during the operation, ensuring the safety and recovery effect of the patient.
