[0018] As shown in Figures 1-9 The present embodiment provides a surgical suture fixing device, which comprises a storage bin 1 and a control mechanism 2.

[0019] As shown in Figure 1 and Figure 2 The bottom of the storage bin 1 is provided with a wrist strap 11, which is a magic tape, used to fix the storage bin 1 on the wrist of a medical staff. As shown in Figures 5-9As shown, the winding reel 12 is rotatably installed in the storage bin 1, the suture 13 is wound on the winding reel 12, the storage bin 1 is provided with the wire outlet 14 on one side, the two rotating columns 15 are rotatably installed in the storage bin 1 on the upper and lower sides of the wire outlet 14, the two rotating columns 15 are respectively provided with the pressing wheels 151, the suture 13 is pressed between the two pressing wheels 151 and passes out of the wire outlet 14. Preferably, the edges of the two pressing wheels 151 are respectively provided with shallow grooves, the suture 13 is pressed between the two shallow grooves, which is beneficial to prevent the suture 13 from deviating from the pressing wheels 151. The two rotating columns 15 are respectively provided with the gears 152 which are engaged with each other, when one of the rotating columns 15 rotates, the other rotating column 15 is synchronously driven to rotate in the opposite direction through the gears 152, so that the suture 13 can be pushed out of the wire outlet 14 by the two pressing wheels 151.

[0020] The control mechanism 2 is used to drive one of the rotating columns 15 to rotate, so that the suture 13 is pushed out of the wire outlet 14 by the pressing wheels 151.

[0021] In specific use, the suture 13 is wound and stored on the winding reel 12 of the storage bin 1, which is helpful to store sufficient length of the suture in the storage bin 1 for subsequent use. The medical staff can drive one of the rotating columns 15 to rotate through the control mechanism 2, and then drive the two pressing wheels 151 to synchronously rotate in the opposite direction through the two gears 152, so that the suture 13 is pushed out of the wire outlet 14, which can meet the needs of suture and will not be too much to hinder the wound suture operation, thereby providing convenience for the medical staff operation.

[0022] Specifically, the control mechanism 2 comprises a palm holding block 21, a first air chamber 22, a second air chamber 23 and a ratchet wheel 24, both sides of the palm holding block 21 are provided with a hand binding belt 211, the hand binding belt 211 can be selected as a magic tape to be bound on the patient's hand, so that the palm holding block 21 can be located at the palm position of the medical staff, the first air chamber 22 is installed at the bottom of the palm holding block 21, the bottom of the first air chamber 22 is slidingly inserted with a first piston column 221, the first piston column 221 is tightly combined with the inner wall of the first air chamber 22, the first piston column 221 is connected with the first air chamber 22 inside the first spring 222 to provide the elastic force for pushing the first piston column 221 out of the first air chamber 22, the ratchet wheel 24 is installed on one of the rotating columns 15, the second air chamber 23 is installed on the inner wall of the storage chamber 1, one end of the second air chamber 23 is communicated with the first air chamber 22 through a first air pipe 231, the other end is slidingly inserted with a second piston column 232, the second piston column 232 is tightly combined with the inner wall of the second air chamber 23, the inner end of the second piston column 232 and the second air chamber 23 are connected with the second spring 233 to provide the elastic force for pulling the second piston column 232 into the second air chamber 23, the outer end of the second piston column 232 is rotationally connected with a pawl 234, a torsion spring is installed on the rotation connection point of the pawl 234 to provide the elastic force for abutting the end of the pawl 234 with the outer edge of the ratchet wheel 24, when the second piston column 232 extends out of the second air chamber 23, the pawl 234 will abut and drive the ratchet wheel 24 to rotate.

[0023] In the initial state, the first piston column 221 can be pushed out of the first air chamber 22 by the first spring 222, and at the same time, the second piston column 232 can be pulled into the second air chamber 23, in specific use, when the medical staff holds the tweezers with the thumb and index finger, the remaining three fingers can be put into the palm and pressed on the outer end of the first piston column 221, when a certain length of suture 13 needs to be taken out, only the remaining three fingers need to be pressed on the first piston column 221, the pressure will be transmitted to the second air chamber 23 through the first air pipe 231, so that the second piston column 232 is pushed out of the second air chamber 23, and then the ratchet wheel 24 is driven to rotate by the pawl 234, so that the two pressing wheels 151 drive the two pressing wheels 151 to push the suture 13 out of the storage chamber 1, and then the medical staff can release the three fingers, so that the first piston column 221 is pushed out of the first air chamber 22 again, and the second piston column 232 is pulled into the second air chamber 23, and when the second piston column 232 is recovered, the pawl 234 will not abut and drive the ratchet wheel 24 to rotate, completing the taking of a certain length of suture 13 at a time, according to the needs of subsequent use, the first piston column 221 can be pressed repeatedly, and the suture 13 can be taken as needed, which is convenient to use.

[0024] Furthermore, the second air chamber 23 is arranged in an arc shape around the ratchet 24, and the center of the arc of the second air chamber 23 is the center of the ratchet 24, so that the moving path of the second piston rod 232 can be matched with the curvature of the ratchet 24, ensuring that the pawl 234 can always be in close contact with the surface of the ratchet 24 under the elastic force of the torsion spring.

[0025] Preferably, it also includes a locking mechanism 3, which includes a third air chamber 31 and a second air pipe 32. The third air chamber 31 is installed in the storage compartment 1. One end of the third air chamber 31 is connected to the first air chamber 22 through the second air pipe 32, and the other end is slidably inserted with a third piston column 311. The third piston column 311 is tightly fitted with the inner wall of the third air chamber 31. A locking block 312 is provided on one side of the outer end of the third piston column 311. A third spring 313 is connected to the inner end of the third piston column 311 and the interior of the third air chamber 31 to provide an elastic force to pull the third piston column 311 into the third air chamber 31 and to make the locking block 312 abut against the side wall of one of the pressure rollers 151. When the medical staff does not press the first piston column 221, the third piston column 311 is pulled into the third air chamber 31 under the elastic force of the third spring 313, so that the locking block 312 can press against the pressure delivery wheel 151, providing rotational resistance to the pressure delivery wheel 151 and preventing the pressure delivery wheel 151 from rotating uncontrollably. When the first piston column 221 is pressed, part of the pressure is transmitted to the second air chamber 23 through the first air pipe 231, and another part of the pressure is transmitted to the third air chamber 31 through the second air pipe 32, so that the third piston column 311, along with the locking block 312, moves away from the surface of the pressure delivery wheel 151, releasing the rotation restriction of the pressure delivery wheel 151. When the first piston column 221 is reset, the third piston column 311 will again press against the pressure delivery wheel 151 under the elastic force of the third spring 313 to reposition itself, which helps to prevent the suture 13 from being uncontrollably taken out of the storage chamber 1 when the suture 13 is not being used.

[0026] Preferably, the side wall where the pressure roller 151 abuts against the locking block 312 has a plurality of locking teeth 1511 evenly distributed around its circumference, and the locking block 312 can be engaged between any two adjacent locking teeth 1511. When the locking block 312 is engaged between adjacent locking teeth 1511, it can completely restrict the rotation of the pressure roller 151, thus playing a better limiting role.

[0027] Furthermore, it should be noted that the first air chamber 22 is connected to the second air chamber 23 and the third air chamber 31 through the first air pipe 231 and the second air pipe 32 respectively. When the first piston column 221 is pressed, the internal pressure of the first air chamber 22 can be diverted to the second air chamber 23 and the third air chamber 31. However, when the locking block 312 does not release the rotation restriction of the pressure feeding wheel 151, the ratchet 24 connected to the rotating column 15 will not be able to be pushed. Therefore, the pressure will be concentrated in the third air chamber 31 first, and the third piston column 311 will be pushed out first to move the locking block 312 away from the pressure feeding wheel 151. Then the second piston column 232 will be pushed out to push the ratchet 24. This realizes the automatic switching of the pressure concentration position, making the connection between releasing the limit and pushing the ratchet operation smoother and improving the operating experience.

[0028] Preferably, the outer wall of the storage compartment 1 is provided with a first blade 16 facing upwards on the lower side of the outlet 14. The outer wall of the storage compartment 1 is provided with a slide rod 17 that slides up and down on the upper side of the outlet 14. A second blade 171 facing downwards and able to abut and intersect with the first blade 16 is provided on the slide rod 17. A pressing piece 172 is provided at the top of the slide rod 17. A fourth spring 173 is connected between the pressing piece 172 and the top wall of the storage compartment 1. By pressing the pressing piece 172, the slide rod 17 can drive the second blade 171 to abut and intersect with the first blade 16, thereby facilitating the medical staff to cut the suture 13 after suturing.

[0029] Furthermore, there is a gap between the first blade 16 and the second blade 171 and the outlet 14, which helps to leave a certain length of suture 13 outside the outlet 14, making it convenient to pull out the suture 13 for the next use.

[0030] In one embodiment, guide plates 18 are respectively provided on both sides of the edge of the pressure roller 151 inside the storage compartment 1. The guide plates 18 are provided with guide holes 181. The suture 13 passes through one of the guide holes 181 between the two pressure rollers 151 and exits through the other guide hole 181 to the outlet 14. This helps to guide the movement of the suture 13 and prevent the suture 13 from deviating.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
