Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a meniscus suture device. Background Art

[0002] Among the surgical methods for repairing the meniscus, the all-inside suturing technique is widely popular due to its small surgical trauma, short operation time, and short patient recovery time. The meniscus suture is the main surgical instrument required for all-inside suturing surgery.

[0003] After a meniscus injury, a meniscus suture device can be used to suture the damaged part of the meniscus to promote the repair of the meniscus, relieve pain, and facilitate the recovery of the meniscus injury. The meniscus suture device can accurately pass the suture through the meniscus tissue to achieve the suture of the meniscus and ensure the reliability and stability of the surgical effect. At the same time, the meniscus suture device does not require additional incisions during the operation. The device is introduced into the body through minimally invasive technology, which reduces the harm of the operation to the patient and reduces the risk of surgery.

[0004] However, when a common meniscus suture device is used for suturing, it can only be judged whether the implant in the puncture needle is fully implanted by observing under a microscope, which causes inconvenience to the doctor's operation and makes it impossible to quickly identify the implantation status of the implant. Summary of the invention

[0005] In order to simplify the method of identifying the implantation status of the implant, shorten the operation time and reduce the surgical risk, the present application provides a meniscus suture device.

[0006] The present application provides a meniscus suture device, which adopts the following technical solution:

[0007] A meniscus suture device, comprising:

[0008] case,

[0009] A suturing needle assembly, the suturing needle assembly comprising a puncture needle and a sleeve sleeved outside the puncture needle, one end of the puncture needle being fixed in the housing, and one end of the sleeve being slidably connected in the housing;

[0010] A pushing assembly, the pushing assembly comprising a push rod and a push block disposed at one end of the push rod, wherein one end of the push rod away from the push block slides in the puncture needle and is used to drive the puncture needle to launch an implant preset in the puncture needle;

[0011] A trigger handle, the trigger handle is rotatably disposed on the housing, and one end of the trigger handle can abut against the push block, and the push block can slide when the trigger handle rotates;

[0012] A prompt sound generating component, when the trigger handle drives the push block to slide, the prompt sound generating component can be driven to make a sound;

[0013] The suturing needle assemblies are provided in plurality, the pushing assemblies are provided in plurality and are arranged one-to-one with the suturing needle assemblies, the prompt sound generating assemblies are provided in plurality and are arranged one-to-one with the pushing assemblies, and a sliding hole for the trigger handle to slide is provided on the shell, and the trigger handle can abut against different pushing blocks when sliding.

[0014] By adopting the above technical solution, the trigger handle is rotated so that the trigger handle drives the push block to move toward the direction close to the suture needle assembly, and the push rod slides simultaneously with the push block, thereby driving the implant in the puncture needle to be launched; when the implant is fully implanted, the prompt sound generating component emits a prompt sound under the action of the trigger handle to remind the doctor that the implantation is complete. The implantation status of the implant can be judged without microscopic observation during implantation, which shortens the operation time and reduces the surgical risk. In addition, the suture needle assembly is provided with multiple suture needle assemblies. After sliding the trigger handle so that the trigger handle is opposite to different push assemblies, the trigger handle can be rotated so that one end of the trigger handle can be against different push blocks to drive different push assemblies to perform push actions respectively, respectively launch implants in different suture needle assemblies, and realize multiple sutures at the sutured part, thereby streamlining the surgical process; the prompt sound generating component is arranged in a one-to-one correspondence with the suture needle assembly, and multiple prompt sounds are emitted in sequence as multiple sutures are completed.

[0015] Optionally, one end of the trigger handle is located in the shell, and the push block is provided with a receiving groove for receiving the one end of the trigger handle.

[0016] By adopting the above technical solution, the trigger handle is rotated to drive one end of the trigger handle located in the shell to rotate into the accommodating groove and abut against the inner wall of the accommodating groove. As the trigger handle continues to rotate, one end of the trigger handle drives the push block to slide, and the push rod slides with the push block to drive the puncture needle to launch the implant and perform suturing. The setting of the accommodating groove improves the movement stability when the trigger handle drives the push block to slide.

[0017] Optionally, a reset member is connected between the push block and the inner wall of the shell, and the reset member is used to drive the push block to move in a direction away from the suture needle assembly.

[0018] By adopting the above technical solution, when the pushing assembly is pushed toward the direction close to the suture needle assembly under the action of the handle, after completing one pushing action, the doctor releases the trigger handle, and the reset member drives the pushing assembly to slide to the initial position. Since one end of the trigger handle is located in the accommodating groove, the trigger handle can be driven to rotate to the initial position when the push block is reset.

[0019] Optionally, the prompt sound generating assembly includes a sound-generating plate disposed in the shell and a paddle disposed on the push block, and the paddle can hit the sound-generating plate when the push block slides.

[0020] By adopting the above technical solution, when the push block slides to the preset position under the action of the trigger handle, the paddle on the push block will collide with the generating plate to emit a prompt sound to remind the doctor that one suturing has been completed.

[0021] Optionally, the prompt sound generating assembly includes a limit knocking rod and a force applying member, the limit knocking rod is rotatably arranged in the shell, and the force applying member is used to drive the limit knocking rod to rotate;

[0023] By adopting the above technical solution, before the trigger handle is rotated, the limit knocking rod is against the limit column; when the trigger handle is rotated to drive the implant in the puncture needle to be fired, the limit knocking rod gradually separates from the limit column; when the trigger handle drives the push block to slide to the preset position, the limit knocking rod is completely separated from the limit column, and the force-applying member drives the limit knocking rod to rotate in a direction close to the abutment surface to knock on the abutment surface, thereby generating a prompt sound to remind the doctor that a suture has been completed.

[0024] Optionally, a mounting column and an abutment column are arranged at intervals in the shell, the force-applying member includes a torsion spring, and a first abutment portion and a second abutment portion are respectively arranged at both ends of the torsion spring, the first abutment portion abuts against the limit knocking rod, and the second abutment portion abuts against the abutment column.

[0025] By adopting the above technical solution, the torsion spring is installed in the shell through the mounting column, the first abutment portion of the torsion spring abuts against the limit knocking rod, and the second abutment portion abuts against the abutment column. When the limit knocking rod abuts against the limit column, the torsion spring is in a compressed state; when the limit knocking rod is completely separated from the limit column, the torsion spring returns to its original state and drives the limit knocking rod to rotate in a direction close to the abutment surface to knock on the abutment surface.

[0026] Optionally, a driving member for driving the sleeve to slide is slidably provided on the shell, and the sleeve can be locked after sliding.

[0027] By adopting the above technical solution, the driving member drives the sleeve to slide, changes the relative position between the sleeve and the puncture needle, and adjusts the size of the puncture needle exposed outside the sleeve, so that the exposed size of the puncture needle is adapted to the damage of the meniscus. The sleeve can be locked after sliding, so that the sleeve is not easily displaced after sliding to a suitable position.

[0033] In summary, the present application includes at least one of the following beneficial effects:

[0034] 1. The present application is provided with a prompt sound generating component. When the trigger handle drives the implant to be fully released, the prompt sound generating component emits a prompt sound under the action of the trigger handle to remind the doctor that the implantation is complete.

A column 143 is integrally formed on the inner wall of the second shell 14, and the column 143 is arranged close to the sliding hole 11 and passes through the trigger handle 4 to realize the rotational connection of the trigger handle 4 on the shell 1. A trigger block 41 is integrally formed at one end of the trigger handle 4 located in the shell 1. A receiving groove 321 is provided on the side of the push block 32 away from the transverse guide rail 17. In this embodiment, the openings of the receiving grooves 321 on the two push blocks 32 are arranged opposite to each other, the column 143 is specifically arranged in a cylindrical shape, and the trigger block 41 is arranged in a circular ring shape. The trigger handle 4 is slid along the axial direction of the column 143, so that the trigger block 41 moves to correspond to an accommodating groove 321, and the trigger handle 4 is rotated to drive the trigger block 41 to move in the direction close to the mounting plate 23; when the trigger block 41 moves, it is first engaged in the accommodating groove 321, and then abuts against the inner wall of the accommodating groove 321, pushing the push block 32 to move in the direction close to the puncture needle 21, so as to drive the puncture needle 21 to launch the implant.

[0058] In other embodiments, the receiving groove 321 may not be provided, so that the trigger block 41 on the trigger handle 4 directly abuts against the end of the push block 32 away from the push rod 31 to drive the push block 32 to slide.

[0059] refer to Figure 2Two groups of prompt sound generating components 5 and two groups of pushing components 3 are also arranged in the housing 1, and the prompt sound generating components 5 are arranged one by one with the pushing components 3. The two groups of prompt sound generating components 5 are specifically arranged as a first prompt sound generating component and a second prompt sound generating component. The first prompt sound generating component includes a limit knocking rod 53 and a force applying member, and the force applying member is specifically arranged as a torsion spring 54.

[0060] refer to Figure 3 , the housing 1 is fixed with a mounting post 145 and an abutting post 144 at intervals, and the mounting post 145 is located below the trigger block 41. In this embodiment, the mounting post 145 is fixed to the inner side wall of the second housing 14, the abutting post 144 is fixed to the inner side wall of the second housing 14, and a plug-in cylinder for partially plugging the abutting post 144 is fixed to the inner side wall of the first housing 13. A sleeve 531 is integrally formed at one end of the limit knocking rod 53, and the sleeve 531 is sleeved on the mounting post 145 to realize the rotation connection of the limit knocking rod 53 in the housing 1. Reference Figure 2 The torsion spring 54 is sleeved on the sleeve 531, and the two ends of the torsion spring 54 are respectively set as the first abutment portion and the second abutment portion. A limit block 532 is integrally formed on the side of the limit knocking rod 53, one end of the first abutment portion abuts between the limit block 532 and the limit knocking rod 53, and the second abutment portion abuts on the abutment column 144.

[0061] refer to Figure 2 and Figure 5 The end of the trigger handle 4 close to the trigger block 41 is fixed with a limit column 42, and the end of the limit knocking rod 53 away from the sleeve is located above the limit column 42 and abuts against the limit column 42; the area of ​​the trigger handle 4 close to the column 143 (not shown in the figure) is provided with a clearance groove, the limit column 42 is located between the clearance groove and the trigger block 41, and the bottom wall of the clearance groove is set as the abutment surface 43. When the trigger handle 4 is rotated to drive the push block 32 to slide in the process of driving the implant to be launched, the limit knocking rod 53 gradually separates from the limit column 42; when the trigger handle 4 drives the push block 32 to slide to the preset position, the limit knocking rod 53 is completely separated from the limit column 42, and the force member drives the limit knocking rod 53 to rotate in the direction close to the abutment surface 43 to knock the abutment column 144, thereby generating a prompt sound to remind the doctor that the suturing is completed.

[0062] refer to Figure 6 and Figure 7The second prompt sound generating assembly includes a sounding piece 52 and a paddle 51. The sounding piece 52 is located between the push block 32 and the mounting plate 23, and the sounding piece 52 is fixed on the inner wall of the second housing 14. The paddle 51 is fixed to one end of a push block 32 close to the sounding piece 52. After the trigger handle 4 is rotated for the first time and reset, it is necessary to slide the trigger handle 4 along the axis direction of the column 143 to move the trigger block 41 on the trigger handle 4 to correspond to the push block 32 on which the paddle 51 is installed. A limit stop bar 322 is fixed at the lower end of the push block 32 on which the paddle 51 is installed. When the trigger handle 4 slides toward the push block 32 close to the paddle 51, the trigger handle 4 can abut against the limit stop bar 322, reducing the probability that the trigger block 41 deviates from the push block 32 after sliding with the trigger handle 4, which helps the trigger handle 4 to smoothly drive the push block 32 to slide.

[0063] refer to Figure 6 and Figure 7 When the push block 32 slides under the action of the trigger handle 4 to implant the implant in place, the paddle 51 hits the sounding piece 52 to produce a prompt sound, reminding the doctor that the suturing is completed. In this embodiment, the end of the sounding piece 52 close to the push rod 31 is set in a trapezoidal shape, so that the paddle 51 can pass through the sounding piece 52 when hitting the sounding piece 52.

[0064] The implementation principle of a meniscus suture device in the embodiment of the present application is as follows: hold the bottom of the housing 1, insert one end of the suture needle assembly 2 into the joint, and push the adjustment push block 61 to slide to a suitable position according to the damaged state of the meniscus, so that the size of the puncture needle 21 exposed outside the sleeve 22 is appropriate. Before the trigger handle 4 is turned for the first time, the limit knocking rod 53 is located above the limit column 42 and abuts against the limit column 42, and the driving block of the trigger handle 4 corresponds to the push block 32 without the paddle 51 installed. When the trigger handle 4 is turned, the push block 32 slides under the action of the trigger block 41, and in the process of driving the implant to release, the limit knocking rod 53 gradually disengages from the limit column 42; when the trigger handle 4 drives the push block 32 to slide to the preset position, the limit knocking rod 53 is completely disengaged from the limit column 42, and the torsion spring 54 drives the limit knocking rod 53 to rotate in the direction close to the abutment surface 43 to knock against the abutment column 144, thereby generating a prompt sound to remind the doctor that the first suture has been completed. After one suturing is completed, the trigger handle 4 is released, and the push block 32 slides to the initial position under the pull of the reset spring 33. The trigger block 41 rotates with the sliding of the push block 32, driving the trigger handle 4 to return to the initial position.

[0065] Subsequently, the trigger handle 4 is slid so that the trigger block 41 corresponds to the push block 32 equipped with the paddle 51, and the trigger handle 4 is turned again, and the push block 32 slides under the action of the trigger block 41; when the push block 32 slides under the action of the trigger handle 4 so that the implant is implanted in place, the paddle 51 hits the sounding piece 52 to produce a prompt sound, reminding the doctor that the second suture has been completed.
