DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0036] Example 1:

[0037] See also Figures 1 to 7 The present embodiment provides a technical solution: a black needle suture thread locking device, including: a base 1, a slide groove 2, a slide rod 3, a half ring part 1 4, a half ring part 2 5, a wire inlet 7, an opening and closing mechanism and a rotating mechanism.

[0038] More specifically, in this embodiment: during actual use, the switching mechanism will operate the opening and closing mechanism, so that the device opens a gap to facilitate the direct placement of multiple sutures into the interior of the device, and then the gap is closed after placement, thereby preventing the sutures from slipping out of the device. When the rotating mechanism is in operation, multiple sutures can be positioned. When positioning, it is convenient for medical staff to adjust the tension of the sutures in time, and the sutures can be locked and fixed after positioning, so that there is no need for manual locking, and there is no need for multiple medical staff to tighten the sutures and use tweezers to tie the sutures, thereby improving convenience and practicality.

[0039] It is worth noting that this embodiment also includes: a switching mechanism and a wetting mechanism.

[0040] More specifically, in this embodiment: during actual use, the opening and closing mechanism and the rotating mechanism can be operated in sequence through the operation of the switching mechanism, and when operating, the other non-operating mechanism can be directionally restricted to operate, thereby making the operation of the opening and closing mechanism and the rotating mechanism more stable and effective, and the wetting mechanism is driven by the rotating mechanism, thereby being able to wet multiple black needle sutures, thereby improving the stability when locking the sutures, avoiding the sutures from slipping, and being able to disinfect the positions in the device that are in contact with the sutures and other components, and the level of intelligence is better.

[0041] Example 2:

[0042] Based on the above embodiment:

[0043] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The switching mechanism in the first embodiment is disclosed as follows. The switching mechanism includes:

[0044] The mounting plate 9 is fixedly connected to the upper surface of the base 1 at the lower surface of the mounting plate 9, and the end of the mounting plate 9 is fixedly connected to the motor 10. The rotating part of the motor 10 is fixedly connected to the dual-axis drive source 11 through the mounting piece. The two rotating parts of the dual-axis drive source 11 are respectively fixedly connected to the friction wheel 12 and the friction wheel 2 13. The end of the semi-ring member 2 5 is fixedly connected to the rotating shaft. The end of the semi-ring member 1 4 is provided with an opening 1 for the rotating shaft to pass through and is connected to the fixed axis rotation. The end of the rotating shaft is fixedly connected to the friction disk 14. The outer shell of the elastic telescopic rod 16 is fixedly connected to the side of the mounting piece. The end of the retraction rod 16 is set as an arc, and a sliding groove for sliding connection of the resisting member 17 is opened on the inner wall of the semi-ring member 4, and arc surfaces are opened on the upper and lower surfaces of the resisting member 17. A limiting rod 18 is fixedly connected to the inner wall of the semi-ring member 4, and a slider 19 is slidably connected to the outer surface of the limiting rod 18. The outer surface of the slider 19 is fixedly connected to the end of the resisting member 17, and a sliding opening for the slider 19 to pass through and be slidably connected to the inner wall of the semi-ring member 4 is opened. Four magnetic blocks 20 are fixedly connected to the inner wall of the semi-ring member 4. The slider 19 is made of metal, and the slider 19 and the magnetic block 20 are magnetically attracted to each other.

[0045] More specifically, in this embodiment: in actual use, when it is necessary to put multiple sutures into the device, the control panel will operate the switching mechanism to operate, so that the friction wheel 12 can contact and frictionally transmit with the friction disk 14 below, thereby driving the opening and closing components to operate, so that the sutures can smoothly enter the interior of the device. When it is necessary to lock multiple sutures, the switching mechanism drives the rotating part of the motor 10 to operate, so that the dual-axis drive source 11 rotates, so that the friction wheel 12 and the friction disk 14 are in contact and friction with each other, and the friction wheel 2 13 and the two friction rings 15 are in contact and friction with each other, thereby achieving the purpose of driving the opening and closing mechanism and the rotating mechanism in sequence. In order to avoid the situation where the mechanism operates after switching, when the dual-axis drive source 11 revolves, it drives the elastic telescopic rod 16 to rotate accordingly. Figure 5 As shown, the end of the elastic telescopic rod 16 will press against the upper surface of the resisting member 17, which will overcome the magnetic attraction of the upper magnetic block 20, thereby driving the resisting member 17 to move downward. When the resisting member 17 moves down to the end, the magnetic block 20 below gives the slider 19 a supporting force, and the slider 19 cannot move further downward. Since the end of the elastic telescopic rod 16 is arc-shaped and the upper surface of the resisting member 17 has an arc-shaped inclined setting, the elastic telescopic rod 16 is contracted, and finally the elastic telescopic rod 16 is located below the resisting member 17 to complete a switching. At this time, after the slider 19 moves down, its end will be against the friction disk 14, thereby achieving the effect of limiting its rotation to avoid the friction disk 14 from being stably driven even if there is no When the force is applied, deflection instability may occur, thereby applying a vertical pressure to the friction disc 14. When it is necessary to switch again, the elastic telescopic rod 16 rotates from the bottom to the top, and the end of the elastic telescopic rod 16 presses against the lower surface of the resisting member 17, driving the resisting member 17 to move upward. Similarly, the above process eventually causes the end of the resisting member 17 to resist the lower surface of the friction ring 15, thereby limiting the rotation of the friction ring 15, and thus limiting the rotation of the semi-ring member 1 4, thereby facilitating the rotation of the semi-ring member 2 5. When the switching is completed, this method has the purpose of driving the opening and closing mechanism or the rotating mechanism, and can limit the operation of another non-operating mechanism during the switching process, thereby improving stability and practicality.

[0046] The magnetic attraction between the slider 19 and the magnet 20 is much smaller than the elastic force inside the elastic telescopic rod 16 . The elastic force inside the elastic telescopic rod 16 will retract only when the resisting member 17 cannot move further.

[0047] Example 3:

[0048] Based on the above embodiment:

[0049] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The opening and closing mechanism in the first embodiment is disclosed as follows. The opening and closing mechanism includes:

[0050] The two side shells 6 have their ends fixedly connected to the upper surfaces of the semi-ring member 1 4 and the semi-ring member 2 5 , respectively. A wire outlet 8 is provided on the upper surface of the side shells 6 .

[0051] More specifically, in this embodiment: in actual use, when the suture needs to enter the interior of the device, because the device has a form of synchronous positioning of multiple sutures, in order to avoid the sutures from slipping out, it is necessary to select a closed form for operation, and the closed form may need to be inserted from the bottom of the device when the suture enters the device, but when it is used for multiple sutures, the operation is more troublesome, because the specifications of the suture itself are not large, just like the form of threading a needle, so the operation is more difficult. This method drives the opening and closing mechanism to operate through the operation of the switching mechanism, so that the friction wheel 12 rotates tiltedly and performs friction transmission with the friction disk 14, and then drives the semi-ring member 2 5 to rotate with the rotating shaft as the center of the circle. When rotating, Figure 1 As shown, the side shell 6 on the left can be rotated counterclockwise, thereby forming an entry port between the semi-ring member 1 4 and the semi-ring member 2 5. At this time, multiple sutures are placed into the interior of the device through the entry port 7 and the action of the opening and closing mechanism. After the placement is completed, the control mechanism is driven again to make the opening and closing mechanism reverse, thereby closing the opening and closing mechanism, thereby preliminarily locking and positioning the multiple sutures to prevent the sutures from suddenly slipping out after being placed in the device. This method is especially convenient during surgery because medical staff do not need to use surgical tweezers to clamp the sutures through the device. After the device is placed in the area to be locked, multiple sutures can be directly placed into the device. This method is more convenient and practical, and the device does not affect the operation of the subsequent rotating mechanism after opening and closing, thereby being more novel.

[0052] When the semi-ring member 2 5 is deflected, the components on it move accordingly, and the slide bar 3 below the semi-ring member 2 5 will not exceed the inner side of the annular container 21. When it moves to this state, multiple sutures can be smoothly inserted and removed.

[0053] Example 4:

[0054] Based on the above embodiment:

[0055] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 7 The rotating mechanism in the first embodiment is disclosed as follows. The rotating mechanism includes:

[0056] Two friction rings 15 are fixedly connected to the side surfaces of the half ring part 1 4 and the half ring part 2 5 respectively. The friction wheel 2 13 is frictionally driven with the friction ring 15. The two friction rings 15 are close to each other. The friction wheel 2 13 can be frictionally driven with the two friction rings 15 after switching. The lower surface of the annular container 21 is fixedly connected to the upper surface of the base 1. The upper surface of the annular container 21 is slidably connected with an annular cover 22. The annular cover 22 slides in an annular groove provided on the inner wall of the annular container 21. Three rotating tubes 24 are provided on the upper surface of the annular cover 22, and a threaded groove 25 is opened on the outer surface of the rotating tube 24. The rotating tube 24 is threadedly connected to a moving block 26 through the threaded groove 25. The end of the moving block 26 is fixedly connected to a positioning shell 27 and a locking block 28. The positioning shell 27 and the opposite side of the semi-ring member 4 are jointly fixedly connected to a telescopic rod 29. A support rod 35 is fixedly connected to the upper surface of the base 1, and the end of the support rod 35 is fixedly connected to a rack row 36. The outer surface of the rotating tube 24 is fixedly connected to a gear 37.

[0057] More specifically, in this embodiment, during actual use, the switching mechanism is operated so that the friction wheel 2 13 deflects to the left, as shown in FIG. Figure 5As shown, the friction wheel 2 13 is in contact with the two friction wheels. At this time, through the operation of the switching mechanism, the friction wheel 2 13 and the two friction wheels are frictionally transmitted, thereby driving the two friction rings 15 to rotate, and then driving the two side shells 6 to rotate. At this time, during the rotation, the gear 37 and the rack row 36 will produce a relative motion relationship, and then under the meshing transmission, the gear 37 and the rotating tube 24 are rotated. Under the sliding restriction of the threaded transmission and the telescopic rod 29, the three positioning shells 27 are finally moved toward the center of the device, and then the multiple sutures passing through the inside of the device are repositioned. When positioned at the center, due to the different relative heights of the positioning shells 27, there will be no contact and jamming. Finally, after the positioning is completed, the locking block 28 is squeezed and locked with the multiple sutures to achieve locking. Purpose: When the positioning shell 27 performs center positioning on the suture, it is not in a locked state at this time, and the medical staff can pull the corresponding suture to adjust the tightness of the suture. Because in the actual surgical process, when dealing with a larger trauma site, not only multiple sutures are required for stitching, but also a certain tensioning force needs to be applied to prevent the suture from loosening and causing the wound to reopen, and thus it is necessary to adjust the tension of the suture. This method has the form of first positioning, then adjusting the tightness, and finally locking. It can solve the problem in the prior art that it is inconvenient to adjust the tightness of the suture after knotting and locking it. Moreover, this method is applied to the use of multiple sutures, and multiple sutures can be positioned together, which is convenient for centralized locking to avoid the suture from loosening and slipping, and it is convenient for locking the suture and for medical staff to tighten the suture.

[0058] Embodiment 5:

[0059] Based on the above embodiment:

[0060] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 7 The wetting mechanism in the first embodiment is disclosed as follows. The wetting mechanism includes:

[0061] The piston cylinder 30, the lower surface of the piston cylinder 30 is fixedly connected to the upper surface of the annular cover 22, the lower surface of the piston cylinder 30 is fixedly connected to the upper surface of the annular cover 22, the inner wall of the piston cylinder 30 is slidably connected with a piston head, the upper surface of the piston head is fixedly connected to a piston rod, the end of the piston rod is fixedly connected to an upper plate 31, and the upper plate 31 and the opposite side of the piston cylinder 30 are jointly fixedly connected to a spring 32. The outer surface of the piston cylinder 30 is fixedly connected with a liquid inlet pipe and a liquid outlet pipe 33, and the interior of the liquid inlet pipe and the liquid outlet pipe 33 are both provided with a one-way valve. The upper surface of the annular cover 22 is provided with an opening 2 for the liquid inlet pipe to pass through, and the end of the liquid outlet pipe 33 is rotatably connected to the end of the rotating tube 24 and is connected to the rotating tube 24. The outer surface of the rotating tube 24 is fixedly connected with a cam 34, and the moving block 26 is communicated with the positioning shell 27, and the positioning shell 27 is provided with an atomizing nozzle on the side facing the suture line.

[0062] More specifically, in this embodiment: when the rotating mechanism is running, it will drive the rotating tube 24 to rotate, thereby causing the cam 34 to rotate. Due to the intermittent pressing relationship between the cam 34 and the upper plate 31, and the vertical movement reset of the upper plate 31, the piston rod and the piston head will reciprocate, thereby causing the pressure inside the piston cylinder 30 to change, so that the disinfectant in the annular container 21 can be extracted through the liquid inlet pipe, and then output to the rotating tube 24 through the piston cylinder 30 and the liquid outlet pipe 33. The end of the rotating tube 24 is then input into the moving block 26 and the positioning shell 27, and finally sprayed by the atomizing nozzle. This method has the following advantages: when the suture thread is centrally positioned by the positioning shell 27, the atomizing nozzle sprays atomized disinfectant, which can make The black needle suture at the position is moistened, and when moistened, it is convenient for the subsequent locking block 28 to increase the force between the two when locking the suture, thereby preventing the suture from slipping, making the stability of the knotting and locking the suture better, and preventing the suture from becoming loose. After the suture is moistened, the influence of air blowing is also reduced, so the suture will not sway with the wind, thereby achieving multiple benefits at one stroke. When the rotating mechanism is reversed and reset, the multiple positioning shells 27 are away from each other and the positioning shells 27 are in the form of facing each other. When the rotating mechanism is reversed at this time, the atomized disinfectant will be sprayed toward the structure inside the device, thereby achieving the purpose of disinfecting the device, and then it can be used effectively before and after the operation.

[0063] Among them: this method adopts the piston cylinder 30 and the liquid outlet pipe 33 to position the rotating tube 24 to achieve the fixed axis limit. When the side shell 6 rotates as a whole, the following movement of the piston cylinder 30 can make the annular cover 22 below rotate and slide in the annular container 21, thereby always driving the rotating tube 24 to limit the fixed axis. Since the semi-ring member 2 5 needs to be deflected in the first state, the corresponding wetting mechanism thereon can be not set to avoid the device from getting stuck.

[0064] Working Principle: The black needle suture locking device has the following steps when used:

[0065] Step S1: The user operates on the terminal to control the control panel, which in turn controls the switching mechanism to operate, thereby opening a gap in the device. The medical staff sutures the patient's wound with black needle sutures, and then places multiple sutures into the interior of the device.

[0066] Step S2: First, the notch of the device is closed by the switching mechanism, and then the switching mechanism continues to operate, so that the rotating mechanism can operate. The rotating mechanism can centrally position multiple sutures. During the positioning process, medical staff can timely adjust the tension of the sutures to avoid incomplete tissue closure. Then, the rotating mechanism can synchronously lock and fix multiple sutures.

[0067] Step S3: During the positioning and locking process, the wetting mechanism operates to spray atomized liquid onto the surface of the suture, thereby wetting the suture, thereby improving the locking stability and preventing the suture from slipping.

[0068] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
