Description

Technical Field

[0001] The invention relates to the technical field of black needle suture thread kits, in particular to an anti-falling black needle suture thread kit. Background Art

[0002] Medical sutures refer to special medical threads used for ligation, hemostasis, suture and tissue suturing during surgical operations. They are divided into absorbable sutures and non-absorbable sutures. Black needles are a type of suture needle. After doctors perform surgery on patients, they usually use sutures to assist in repairing the incisions on the patient's body. The doctor performs the operation by passing the suture through the needle, then fixing the open part by suturing, and fixing the suture by tying a knot at the end of the sutured part.

[0003] When using sutures, medical staff need to take a certain length of suture from the thread roller and then cut it. However, when pulling the suture, the thread roller may rotate several more times due to inertia, causing excess suture to fall off after taking the suture. In addition, the surgical thread may sag due to its own gravity and separate from the cut-off point. Various surgical threads may be entangled with each other, making it inconvenient for medical staff to take them. At the same time, in order to ensure the quality of needle threading and the firmness of the knot after tying, it is usually necessary to manually moisten the suture, which further delays time and reduces the efficiency of suture surgery.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Embodiment 1:

[0042] See also Figures 1 to 10 This embodiment provides a technical solution: an anti-falling black needle suture kit, comprising:

[0043] The sleeve comprises a shell 1 and a shell 2, the shell 1 and the shell 2 are fixedly connected by a connecting block, and the shell 1 and the shell 2 are rotatably connected by a ring body 3 through a limiting component;

[0044] An anti-falling component is arranged in the housing 1, and comprises four groups of support plates 5 distributed in a circular array, and the ends of the support plates 5 are all provided with abutment components;

[0045] The ring body 3 and the support plate 5 are connected by a transmission component, and the ring body 3 rotates to drive the multiple groups of support plates 5 to move;

[0046] The cover body 4 is threadedly connected to the surface of the shell body 2, and the surface of the cover body 4 is connected to the support plate 22 through a locking component. The support plate 22 passes through the shell body 2 and is slidably connected thereto. A tensioning component is provided at the bottom of the support plate 22, and the tensioning component includes a rotating drum 33. A wetted component cooperating with the rotating drum 33 is provided on the support plate 22. The surfaces of the shell body 1 and the cover body 4 are both provided with thread holes for the passage of sutures.

[0047] More specifically, in this embodiment: the shell body 1 is first fixedly installed in one place, specifically, it can be installed on the wire box, so that the kit is fixed as a whole, and before the first threading, the limit on the ring body 3 is first released by the limit component, and then the ring body 3 is turned to rotate, and the ring body 3 is rotated to drive the transmission component to move, and the transmission component is moved to drive the anti-falling component to move, and the anti-falling component is moved to drive multiple support plates 1 5 to move away from each other at the same time, and the multiple support plates 1 5 are moved away from each other at the same time, The abutment assembly is driven to move, and at the same time, the limit on the support plate 2 22 is released by the locking component, so that the tensioning component is away from the suture line to prevent the abutment assembly from hindering the entry of the suture line, and then the suture line on the line roller is passed through the line holes on the surface of the shell body 1 and the cover body 4 in turn. After the threading is completed, the ring body 3 is released and automatically reset by the action of the limit component. The anti-falling component is reset by the ring body 3, so that the abutment assembly abuts against the surface of the suture line to limit its moving direction.

[0048] When it is necessary to take out the suture, the ring body 3 is moved to move the abutment component away from the suture, and then one end of the suture is pulled. At this time, the suture maintains a certain tension under the action of the tensioning component, and the rotating drum 33 is continuously in contact with the suture. During the suture taking process, the suture drives the rotating drum 33 to rotate continuously through the friction force. The continuous rotation of the rotating drum 33 drives the wetting component to move during the suture taking process, and the surface of the suture to be used is wetted to ensure that the knot is firm and not easy to slip after being tied. The suture is not loose after being soaked, which is conducive to needle threading, and no manual wetting is required, which saves time and improves suturing efficiency.

[0049] When the suture is taken to a suitable length, the ring body 3 is loosened and the ring body 3 is automatically reset by the action of the limiting component. The reset of the ring body 3 drives the anti-falling component to reset, so that the abutment component abuts against the surface of the suture to limit its moving direction. The suture is then cut off to complete the suture taking. At this time, the friction force of the suture moving toward the cover body 4 will be greatly increased. In contrast, the friction force moving toward the shell body 1 is smaller, thereby avoiding the suture falling off due to the rotation of the wire roller due to inertia when taking the wire, thereby preventing the suture from falling off, and preventing the problem of multiple surgical wires being entangled with each other. This is convenient for medical staff to take and improves the efficiency of suture surgery.

[0050] Embodiment 2:

[0051] Based on the above embodiments:

[0052] See also Figure 1 and Figure 2 The anti-falling component in the first embodiment is disclosed as follows. The anti-falling component includes:

[0053] The abutment plate 16, the surface of the support plate 15 is fixedly connected with the fixing plate 15, the abutment assembly includes a connection block 20 and an arc plate 21 fixedly connected to the bottom of the abutment plate 16, and the inner arc surface of the arc plate 21 is provided with a rubber layer;

[0054] A second fixing plate 18 is fixedly connected to the surface of the first fixing plate 15. A second spring 19 is fixedly connected between the second fixing plate 18 and the abutting plate 16. A stopper 17 is fixedly connected to the surface of the first fixing plate 15. The stopper 17 abuts against the abutting plate 16. In the initial state, the abutting plate 16 is inclined.

[0055] A baffle plate 6 is fixedly connected to one end of a support plate 5 located outside of a shell 1, a telescopic rod 7 is fixedly connected between the bottom of the baffle plate 6 and the surface of the shell 1, a spring 8 is sleeved on the surface of the telescopic rod 7, and two ends of the spring 8 are fixedly connected to the bottom of the baffle plate 6 and the surface of the shell 1 respectively.

[0056] More specifically, in the present embodiment: the ring body 3 rotates, and the transmission components drive the plurality of support plates 5 to approach or move away from each other at the same time, the support plate 5 moves, the fixed plate 15 and the abutment plate 16 move at the same time, the abutment plate 16 moves, the connecting block 20 and the arc plate 21 move, when the arc plate 21 is separated from the suture, the thread can be taken out at this time, and the ring body 3 is reset after the thread is taken out, so that the arc plate 21 is reset to the initial state, and in the initial state, the plurality of arc plates 21 hold the suture from different directions to avoid bending of the suture because it is small and soft, thereby ensuring the limiting effect, because the plurality of abutment plates 16 are all inclined and the rotation direction is limited by the block 17, so when the suture moves toward the cover body 4, the friction force will be greatly increased, and in contrast, the friction force moving toward the shell body 1 is relatively small, thereby achieving the effect of preventing the suture from falling off after taking the thread, and improving the efficiency of taking the thread.

[0057] Also, see Figure 1 and Figure 6 The transmission component in the first embodiment is disclosed as follows: the transmission component includes a fixed block 301, which is fixedly connected to the inner wall of the ring body 3. The number of the fixed blocks 301 corresponds to the support plate 5, and the fixed blocks 301 are distributed on the inner wall of the ring body 3 in a ring array. A rotating plate 9 is hinged between the fixed block 301 and the support plate 5.

[0058] More specifically, in this embodiment: the ring body 3 rotates to drive multiple rotating plates 9 to rotate, and the multiple rotating plates 9 rotate to drive multiple groups of support plates 5 to move simultaneously, and in the initial state, the rotating plates 9 and the support plates 5 are in a horizontal state, so that the rotating plates 9 and the support plates 5 are not easy to shake, thereby improving stability during use.

[0059] Also, see Figure 3 , Figure 4 and Figure 6 The limiting component in the first embodiment is disclosed as follows: the limiting component includes a shift block 10, which is fixedly connected to the surface of the ring body 3, and connecting blocks 11 are fixedly connected on both sides of the shift block 10. The surfaces of the shell 1 and the shell 2 are fixedly connected with fixed blocks 2 12, and the surfaces of the two connecting blocks 11 are fixedly connected with arc rods 13. The surface of the fixed block 2 12 is provided with a through hole 1 for the arc rod 13 to pass through and be slidably connected thereto. The surface of the arc rod 13 is sleeved with an arc tension spring 14, and the two ends of the arc tension spring 14 are respectively fixedly connected to the surfaces of the connecting block 11 and the fixed block 2 12. The arc formed by the center line connecting the two ends of the arc rod 13 is concentric with the ring body 3, and the tension of the arc tension spring 14 is greater than the tension of the spring 1 8.

[0060] More specifically, in this embodiment: in the initial state, the shift block 10 is pressed against by the action of the arc tension spring 14, so that the arc plate 21 remains in abutment. When it is necessary to remove the thread, the shift block 10 is manually moved to drive the ring body 3 to rotate, and the arc rod 13 is driven to slide on the surface of the fixed block 12 through the two connecting blocks 11, while exerting pressure on the arc tension spring 14 to cause it to contract. After the thread is removed, the shift block 10 is released, and the arc tension spring 14 is no longer subjected to pressure. The elastic restoring force of the arc tension spring 14 drives the shift block 10 to reset, thereby driving the arc plate 21 to continue to limit the suture thread, thereby achieving the effect of preventing it from falling off.

[0061] Also, see Figure 1 , Figure 7 and Figure 8 The tensioning component in the first embodiment is disclosed as follows: the tensioning component includes a tensioning wheel 34, two support plates 22, a telescopic rod 2 30 is fixedly connected to the lower surface of the support plate 22, an L-shaped plate 32 is fixedly connected to the end of the telescopic rod 2 30, a spring 31 is sleeved on the surface of the telescopic rod 2 30, two ends of the telescopic rod 2 30 and the surface of the L-shaped plate 32 are provided with a through hole 2 for the rotating drum 33 to pass through, the rotating drum 33 is connected to the L-shaped plate 32 through the through hole 2, and the tensioning wheel 34 is fixedly connected to the surface of the rotating drum 33.

[0062] More specifically, in the present embodiment: the limit of the multi-support plate 22 is released by the locking component, and then the support plate 22 can be moved, and the L-shaped plate 32 is driven to move by the action of the telescopic rod 2 30 and the spring 3 31. The movement of the L-shaped plate 32 drives the tensioning wheel 34 to press on the surface of the suture, and then the locking component is used to limit it, so that the suture maintains tension when the suture is taken out, and the medical staff is subjected to a certain amount of resistance when the suture is taken out, thereby avoiding the situation where the suture falls off quickly due to inertia when the suture is taken out, and improving the stability when the suture is taken out.

[0063] Also, see Figures 7 to 10 The wetted component in the first embodiment is disclosed as follows. The wetted component includes:

[0064] The cylinder 38 is fixedly connected to the surface of the L-shaped plate 32. The surface of the cylinder 38 is respectively fixedly connected with a water inlet hose 39 and a water outlet hose 40. The surfaces of the water inlet hose 39 and the water outlet hose 40 are both provided with a one-way valve. The surface of the support plate 22 is fixedly connected with the water tank 29. The end of the water inlet hose 39 is fixedly connected with the bottom of the water tank 29. The end of the water outlet hose 40 extends into the end of the rotating drum 33 and is connected to the rotating drum 33 in a fixed axis.

[0065] The piston rod 41 and the surface of the cylinder 38 are provided with a through hole three for the piston rod 41 to pass through and be slidably connected thereto. The piston rod 41 and one end located in the cylinder 38 are fixedly connected to the piston 43, and the piston 43 is slidably connected in the cylinder 38. The piston rod 41 and one end located outside the cylinder 38 are fixedly connected to the drive plate 37. The surface of the piston rod 41 is sleeved with a spring four 42, and the two ends of the spring four 42 are respectively fixedly connected to the surface of the drive plate 37 and the surface of the cylinder 38. The surface of the rotating cylinder 33 is fixedly connected to the cam 36, and the cam 36 abuts against the drive plate 37.

[0066] The sponge 35 is annularly arranged and fixedly sleeved on the surface of the tension wheel 34. The surface of the rotating drum 33 is provided with a plurality of water outlet holes 1. The tension wheel 34 is hollow inside and has a plurality of water outlet holes 2 341 on its inner wall.

[0067] More specifically, in this embodiment: during the thread removal process, the tension wheel 34 is always pressed on the surface of the suture through the action of the telescopic rod 2 30 and the spring 31, and has a large friction force with the suture. Therefore, when the suture moves, the tension wheel 34 and the drum 33 are driven to rotate, and the drum 33 rotates, which drives the cam 36 to rotate. The cam 36 rotates continuously, and the spring 42 and the drive plate 37 make the piston rod 41 reciprocate. The piston rod 41 reciprocates, which drives the piston 43 to reciprocate in the cylinder 38, and the saline in the water tank 29 is sucked in through the water inlet hose 39. , and then transported to the drum 33 through the water outlet hose 40. The physiological saline entering the drum 33 enters the tension wheel 34 through the water outlet hole 1 opened on the surface, and then enters the sponge 35 through the water outlet hole 2 341, thereby realizing intermittent water supply to the sponge 35 to keep the sponge 35 moist, so that the sponge 35 can maintain the moist quality of the suture. After the suture is moistened, the damage to the sutured tissue can be reduced, and the knot is firm after being tied, and it is not easy to slip off, and it is not easy to float with the laminar flow in the operating room, air conditioning and other airflows. Moreover, the suture is not loose after being moistened, which is conducive to needle threading. The suture wetting process does not require manual operation, which saves time and improves the efficiency of suture surgery.

[0068] Also, see Figure 3 and Figure 5 The locking component in the first embodiment is disclosed as follows. The locking component includes:

[0069] A driving ring 24 is slidably sleeved on the surface of the cover body 4. A plurality of sets of fixing blocks 3 26 are fixedly connected to the surface of the cover body 4. A guide rod 27 is fixedly connected to the surface of the fixing block 3 26.

[0070] A locking rod 25 is fixedly connected to the surface of the driving ring 24 , a plurality of locking grooves for the locking rod 25 to extend into are provided on the surface of the second supporting plate 22 , and a second baffle is fixedly connected to the top of the second supporting plate 22 .

[0071] More specifically, in this embodiment: by moving the drive ring 24 to slide on the surface of the cover body 4, the locking rod 25 is driven to disengage from the locking groove, and then the support plate 22 can be pulled to move, and after the movement is completed, the drive ring 24 is released, and the elastic restoring force of the limit spring 28 is used to drive the drive ring 24 to reset, so that the locking rod 25 is extended into another locking groove to continue to limit the support plate 22, thereby ensuring the stability of the suture kit during use.

[0072] Embodiment 2:

[0073] Based on the above embodiments:

[0074] See also Figure 1 The surfaces of the cover body 4 and the shell body 1 are respectively fixedly connected with an outlet pipe 401 and an inlet pipe 101, and a plurality of mounting blocks 102 are evenly arranged on the surface of the shell body 1.

[0075] More specifically, in this embodiment: the housing 1 can be fixedly installed by the mounting block 102, and the outlet tube 401 and the inlet tube 101 are provided to guide the suture thread, thereby improving the threading efficiency.

[0076] How it works: The use of this non-shedding black needle suture kit includes the following steps:

[0077] Step S1: The housing 1 is fixedly installed on the wire box by the mounting block 102. When the wire needs to be taken out after the threading is completed, the shifting block 10 is shifted to drive the ring body 3 to rotate, and the multiple groups of support plates 5 are driven to move simultaneously through the multiple rotating plates 9. The multiple groups of support plates 5 move simultaneously, driving the multiple groups of abutment plates 16 and the arc plates 21 to move away from each other, and then pulling the suture to move;

[0078] Step S2: During the suture thread removal process, the tension wheel 34 is always pressed on the surface of the suture thread by the action of the telescopic rod 2 30 and the spring 3 31, and there is a large friction force between the tension wheel 34 and the suture thread, so that when the suture thread moves, the tension wheel 34 and the rotating drum 33 are driven to rotate;

[0079] Step S3: The rotating drum 33 rotates to drive the cam 36 to rotate, and the piston rod 41 and the piston 43 are used to suck the saline in the water tank 29 through the water inlet hose 39 through the spring 42 and the driving plate 37, and then transport it to the rotating drum 33 through the water outlet hose 40. The saline enters the sponge 35 through the water outlet hole 1 and the water outlet hole 2 341, and intermittent water supply is realized to the sponge 35 to keep the sponge 35 moist, so that the sponge 35 can keep the moist quality of the suture, ensure that the knot is firm and not easy to slip, and the suture is not loose after being soaked, which is conducive to needle threading, and no manual wetting is required, which saves time and improves suture efficiency;

[0080] Step S4: After the thread is taken out, release the shift block 10, and drive the shift block 10 and the ring body 3 to reset through the arc tension spring 14, so that the support plate 5 is reset to the initial state. In the initial state of the support plate 5, multiple arc plates 21 hold the suture thread from different wind directions. Since multiple abutment plates 16 are all inclined and the rotation direction is limited by the block 17, the friction force of the suture thread moving toward the cover body 4 will be greatly increased. In contrast, the friction force moving toward the shell body 1 is smaller, thereby achieving the effect of preventing the suture thread from falling off after taking out the thread, avoiding the thread roller from rotating for several more weeks due to inertia when taking out the thread, causing the suture thread to fall off, and preventing the problem that multiple surgical threads may be entangled with each other, which is convenient for medical staff to take and improves the efficiency of suture surgery.
