A vascular suture fixation auxiliary device

Abstract

This utility model provides a vascular suture fixation auxiliary device, relating to the field of medical equipment technology. It includes a base plate, a limiting clip, and a track rod. A locking mechanism is provided between the track rod and the base plate. A positioning frame is provided on the outer side of the track rod via an adjustment mechanism, and a positioning sleeve is provided inside the positioning frame. One end of the adjusting bolt is threaded into the right clamping block, and the right and left clamping blocks mutually limit each other. Tightening the adjusting bolt in both directions causes the right clamping block to rotate up and down around a rotation axis. When the right and left clamping blocks clamp the track rod, the position of the positioning frame is locked. When the right and left clamping blocks release the track rod, the positioning frame can be pushed to slide back and forth along the track rod to adjust its position, making the positioning sleeve parallel to the location on the arm where vascular suture is needed. The vascular suturer is then inserted through the interior of the positioning sleeve to suture the blood vessel, thus confining it to a small area at the suture site and improving the accuracy of the surgical operation.

Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a vascular suture and fixation auxiliary device. Background Technology

[0002] Vascular suturing is a microsurgical technique primarily used to repair damaged blood vessels. It involves two methods: end-to-end anastomosis and end-to-side anastomosis. Through meticulous manipulation, the severed ends or openings of the vessel are aligned and sutured using fine sutures. Vascular suturing requires complete and tight intimal alignment to ensure no leakage, no stenosis of the lumen, and unobstructed blood flow after suturing. This technique is widely used in vascular surgery, effectively inhibiting massive bleeding caused by vascular rupture and promoting patient recovery.

[0003] For example, Chinese patent application number CN202223557396.9 discloses a vascular suture device, which proposes that "before the needle handle needs to be pulled, a temporary limiting plate is used to press the temporary limiting pin under the elastic force of the compression spring, so that the end of the temporary limiting pin is embedded in the temporary limiting groove, thereby limiting the needle handle and preventing the needle handle from sliding accidentally. When the temporary limiting plate is rotated to deviate from the temporary limiting pin, the temporary limiting pin automatically pops out and disengages from the temporary limiting groove under the elastic force of the return spring, and the needle handle can then be pulled, making the operation more convenient and helping to maintain the stability of the vascular suture device." However, the operation is quite difficult, requiring not only the suture device but also the hand to cooperate with the suture thread. Therefore, this utility model proposes a vascular suture fixation auxiliary device to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a vascular suture fixation auxiliary device to solve the issue that the operation of the aforementioned device is difficult, requiring not only a suture device but also hand assistance in using the suture.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a vascular suture fixation auxiliary device, including a base plate, a limiting card and a track rod, wherein the limiting card is hinged to one side of the base plate through a rotating sleeve, and the track rod is fixedly connected to one side of the limiting card, a locking mechanism is provided between the track rod and the base plate, and a positioning frame is provided on the outside of the track rod through an adjustment mechanism, and a positioning sleeve is provided inside the positioning frame.

[0006] A further improvement is that the adjustment mechanism includes a left clamping block, a right clamping block, a rotating shaft, and an adjusting bolt. The left clamping block is provided on the outer side of the track rod, and the right clamping block is hinged to one side of the left clamping block through the rotating shaft. The adjusting bolt is rotatably connected inside the left clamping block, and one end of the adjusting bolt is threadedly connected to the inside of the right clamping block.

[0007] A further improvement is that the positioning frame is designed with an L-shaped structure, the bottom end of the positioning frame is fixedly connected to the top of the left clamping block, and both the left and right clamping blocks have V-shaped grooves inside, with the inner wall of the V-shaped grooves slidingly connected to the outer wall of the track rod.

[0008] A further improvement is that: the positioning frame has a sliding groove inside, and the positioning sleeve is symmetrically fixedly connected with locking bolts on the outside. The two locking bolts pass through the two sides of the sliding groove and are threaded with nuts.

[0009] A further improvement is that a vascular suture device can be inserted into the inside of the positioning sleeve, the diameter of the nut is greater than the height of the slide groove, and the outer wall of the positioning sleeve is slidably connected to the inner wall of the slide groove.

[0010] A further improvement is that the locking mechanism includes a fixing block, a fixing bolt, and a threaded hole. The fixing block is symmetrically fixedly connected to the side of the base plate adjacent to the track rod. Threaded holes are symmetrically provided at both ends of the track rod. Fixing bolts are symmetrically provided at both ends of the track rod. One end of the fixing bolt passes through the interior of the fixing block and is threadedly connected to the inner wall of the threaded hole.

[0011] A further improvement is that: connecting blocks are symmetrically arranged on both sides of the substrate, and mounting holes are provided inside the connecting blocks. Assembly bolts are inserted into the mounting holes, and the connecting blocks are detachably connected to the operating table through the assembly bolts.

[0012] The beneficial effects of this utility model are as follows: one end of the adjusting bolt is threaded into the right clamping block, and the right clamping block and the left clamping block limit each other. Tightening the adjusting bolt in both directions can drive the right clamping block to rotate up and down around the rotation axis, so that the right clamping block and the left clamping block move closer or further apart, thereby controlling whether the outer wall of the track rod is clamped. When the right clamping block and the left clamping block clamp the track rod, the position of the positioning frame can be locked. When the right clamping block and the left clamping block release the track rod, the positioning frame can be pushed to slide back and forth along the track rod to adjust the position, so that the positioning sleeve is parallel to the position on the arm where the blood vessel needs to be sutured. The blood vessel suturer is inserted through the inside of the positioning sleeve to suture the blood vessel, thereby restricting it to a small area at the suture site and improving the accuracy of the surgical operation.

Detailed Implementation

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a vascular suture fixation auxiliary device, including a base plate 1, a limiting clip 2, and a track rod 3. The limiting clip 2 is hinged to one side of the base plate 1 via a rotating sleeve 15. The track rod 3 is fixedly connected to one side of the limiting clip 2. A locking mechanism is provided between the track rod 3 and the base plate 1. A positioning frame 6 is provided on the outer side of the track rod 3 via an adjustment mechanism. A positioning sleeve 12 is provided inside the positioning frame 6. When using the auxiliary device, first, the locking mechanism restricts the track rod 3. Then, the limiting clip 2 is rotated counterclockwise to open the channel above the base plate 1. Next, the patient's arm is placed on the top of the base plate 1, where the top of the base plate 1 has an arc groove. This allows the arm to fit more snugly against the inside of the base plate 1. Then, the limiting card 2 is rotated clockwise so that the track rod 3 on one side engages with the locking mechanism. The locking mechanism locks the position of the limiting card 2, which restricts the arm to the top of the base plate 1. The position of the positioning frame 6 and the positioning sleeve 12 is then adjusted by the adjustment mechanism so that they are parallel to the position on the arm where the blood vessel needs to be sutured. The blood vessel suturer is then inserted through the inside of the positioning sleeve 12 to suture the blood vessel, thus restricting it to a small area at the suture site and improving the accuracy of the surgical operation. After the operation, the limiting card 2 is rotated counterclockwise again to open the channel above the base plate 1, and the patient's arm is removed from the top of the base plate 1.

[0020] The adjustment mechanism includes a left clamping block 7, a right clamping block 8, a rotating shaft 9, and an adjusting bolt 10. The left clamping block 7 is located on the outer side of the track rod 3. The right clamping block 8 is hinged to one side of the left clamping block 7 via the rotating shaft 9. The adjusting bolt 10 is rotatably connected inside the left clamping block 7, and one end of the adjusting bolt 10 is threaded into the inside of the right clamping block 8. The positioning frame 6 is L-shaped, and its bottom end is fixedly connected to the top of the left clamping block 7. Both the left clamping block 7 and the right clamping block 8 have V-shaped grooves inside, and the inner wall of the V-shaped groove is flush with the track rod. The outer wall of the track rod 3 is slidably connected. One end of the adjusting bolt 10 is threaded with the right clamping block 8, and the right clamping block 8 and the left clamping block 7 limit each other. Turning the adjusting bolt 10 in both directions can drive the right clamping block 8 to rotate up and down around the rotating shaft 9, so that the right clamping block 8 and the left clamping block 7 move closer or further apart, which is used to control whether the outer wall of the track rod 3 is clamped. When the right clamping block 8 and the left clamping block 7 clamp the track rod 3, the position of the positioning frame 6 can be locked. When the right clamping block 8 and the left clamping block 7 release the track rod 3, the positioning frame 6 can be pushed to slide back and forth along the track rod 3 to adjust the position.

[0021] The positioning frame 6 has a sliding groove 11 inside. The positioning sleeve 12 is symmetrically fixedly connected with locking bolts 13 on the outside. The two locking bolts 13 pass through the two sides of the sliding groove 11 and are threaded with nuts. A vascular suture device can be inserted into the inside of the positioning sleeve 12. The diameter of the nut is greater than the height of the sliding groove 11. The outer wall of the positioning sleeve 12 is slidably connected to the inner wall of the sliding groove 11. Loosen the nuts at one end of the two locking bolts 13. The nuts no longer clamp the positioning frame 6, releasing the limitation between the locking bolts 13 and the positioning frame 6. At this time, the positioning sleeve 12 can move back and forth in a straight line along the sliding groove 11 to adjust its own position. Then tighten the nuts on the locking bolts 13. The nuts clamp the positioning frame 6 to limit the positioning sleeve 12.

[0022] The locking mechanism includes a fixing block 4, a fixing bolt 5, and a threaded hole 16. The fixing block 4 is symmetrically fixedly connected to the side of the base plate 1 adjacent to the track rod 3. The two ends of the track rod 3 are symmetrically provided with threaded holes 16 and fixing bolts 5. One end of the fixing bolt 5 passes through the interior of the fixing block 4 and is threadedly connected to the inner wall of the threaded hole 16. After unscrewing the two rotating sleeves 15 from the threaded holes 16 at both ends of the track rod 3, the limiting card 2 is rotated counterclockwise to open the channel above the base plate 1, so as to put the patient's arm into the top of the base plate 1 or to take the patient's arm out of the top of the base plate 1. The limiting card 2 is rotated clockwise so that the track rod 3 on one side fits with the fixing block 4. The fixing bolt 5 is screwed into the interior of the threaded hole 16 through the interior of the fixing block 4, so as to connect the fixing block 4 and the track rod 3 into one unit, and to limit the limiting card 2.

[0023] The base plate 1 is symmetrically provided with connecting blocks 14 on both sides. The connecting blocks 14 have mounting holes inside, and mounting bolts are inserted into the mounting holes. The connecting blocks 14 are detachably connected to the operating table through the mounting bolts. The mounting bolts are inserted into the mounting holes inside the connecting blocks 14 and screwed down to move through the inside of the operating table, so as to fix the base plate 1 and the operating table as one unit. The entire auxiliary device can be installed on the operating table.

[0024] This vascular suture fixation auxiliary device has an adjusting bolt 10 with one end threaded into the right clamp 8, and the right clamp 8 and the left clamp 7 mutually limit each other. Tightening the adjusting bolt 10 in both directions can drive the right clamp 8 to rotate up and down around the rotation axis 9, so that the right clamp 8 and the left clamp 7 move closer or further apart, which is used to control whether the outer wall of the track rod 3 is clamped. When the right clamp 8 and the left clamp 7 clamp the track rod 3, the position of the positioning frame 6 can be locked. When the right clamp 8 and the left clamp 7 release the track rod 3, the positioning frame 6 can be pushed to slide back and forth along the track rod 3 to adjust the position, so that the positioning sleeve 12 is parallel to the position on the arm where the blood vessel needs to be sutured. The vascular suturer is inserted through the inside of the positioning sleeve 12 to suture the blood vessel, which is used to limit it to a small area at the suture site and improve the accuracy of the surgical operation.
