Description

Technical Field

[0001] This application relates to the technical field of medical devices, and in particular to a gun-type meniscus repair device. Background Technology

[0002] Currently, during meniscus repair surgery, it is usually necessary to suture the tear in the meniscus. Because the meniscus is located inside the body, doctors typically use a suture gun to minimize the wound and facilitate suturing. A suture gun is a gun-shaped meniscus repair instrument, generally made of metal, and is quite heavy.

[0003] Regarding the aforementioned techniques: When doctors hold a suture gun for a long time to perform detailed operations, it can easily cause a certain degree of soreness and numbness in the doctor's hands, which can adversely affect the doctor's suturing operation. In addition, doctors mainly rely on experience to judge the suture position, which can easily lead to errors and ultimately result in less than ideal surgical outcomes. Summary of the Invention

[0004] To improve surgical outcomes, this application provides a gun-type meniscus repair device.

[0005] The gun-type meniscus repair device provided in this application adopts the following technical solution:

[0006] A gun-type meniscus repair device includes:

[0007] Lifting support;

[0008] A support arm is mounted on the lifting bracket, and a movable component is provided at the end of the support arm away from the lifting bracket.

[0009] A suture gun is connected to the movable component. A depth-limiting sleeve is slidably provided at the muzzle end of the suture gun. A positioning component is provided on the suture gun to assist the depth-limiting sleeve in positioning.

[0010] A locking device is connected to both the movable component and the positioning component, and is used to lock the movable component to fix the position of the suture gun, and to drive the positioning component to move toward the lifting bracket.

[0011] By adopting the above technical solution, the cooperation between the lifting bracket and the support arm can support the suture gun. The movable component improves the flexibility of the doctor in using the suture gun to a certain extent, making it easier for the doctor to use the positioning component to accurately move the depth-limiting cannula to the position to be sutured. At this time, the locking device can lock the movable component, so that the position of the suture gun relative to the movable component is fixed, which is conducive to the doctor to suture the wound accurately, thus achieving the goal of improving the surgical effect to a certain extent.

[0012] Optionally, a slider is slidably provided at the end of the support arm away from the lifting bracket, and the slider is used to drive the movable component and the suture gun to move.

[0013] By adopting the above technical solution, the slider can drive the movable component and the suture gun to move on the support arm, thereby facilitating the adjustment of the position of the suture gun relative to the support arm.

[0014] Optionally, the movable component includes a seal rotatably connected to the slider, with a rotating shaft rotatably connected to the end of the seal away from the slider. The axis of the rotating shaft is perpendicular to the axis around which the seal rotates, and the stitching gun is connected to the rotating shaft.

[0015] By adopting the above technical solution, the suture gun is connected to the seal via a rotating shaft, allowing the suture gun to rotate both with the seal relative to the slider and relative to the seal via the rotating shaft, thereby improving the flexibility of doctors in using the suture gun.

[0016] Optionally, the slider has a rotating groove, the seal has a sealing cavity, the rotating shaft is inserted into the sealing cavity, and the movable component also includes a connector. The connector is slidably inserted into the rotating groove and the sealing cavity, and the connector is rotatably connected to the slider. Anti-slip textures are provided at both ends of the connector, on the circumferential outer wall of the rotating shaft, and on the inner wall of the rotating groove near the seal. The locking device is used to drive the connector to move so that the anti-slip textures on the connector abut against the anti-slip textures on the rotating shaft and the inner wall of the rotating groove, respectively.

[0017] By adopting the above technical solution, when the doctor moves the suture gun to the corresponding position, the locking device can drive the connector to move, so that the anti-slip texture on the connector abuts against the anti-slip texture on the rotating shaft and the inner wall of the rotating groove, thereby reducing the possibility of the suture gun rotating, and thus making it easier to fix the position of the suture gun relative to the slider.

[0018] Optionally, the locking device includes an elastic airbag and an air tube communicating with the elastic airbag. One end of the air tube away from the elastic airbag is connected to the end of the sealing cavity near the slider. The outer wall of the connector is in contact with the inner wall of the sealing cavity.

[0019] By adopting the above technical solution, when the elastic airbag is compressed, the gas stored in the elastic airbag can enter the sealed cavity through the air tube, which to a certain extent increases the gas pressure in the sealed cavity on the side of the connector closer to the slider, thereby facilitating the movement of the connector to achieve the purpose of fixing the position of the suture gun relative to the slider.

[0020] Optionally, the movable component includes a first elastic element that abuts against the slot and the connector, respectively.

[0021] By adopting the above technical solution, when the elastic airbag is no longer compressed, the gas discharged into the sealed cavity flows back into the elastic airbag. At this time, the first elastic element can push the connecting element to move, which helps the connecting element to return to its original position.

[0022] Optionally, the positioning component includes a limiting sleeve and a positioning rod disposed on the limiting sleeve. The limiting sleeve is fitted onto the suture gun, and the end of the positioning rod away from the limiting sleeve is disposed close to the depth limiting sleeve. The positioning rod is used to assist the depth limiting sleeve in positioning.

[0023] By adopting the above technical solution, when the doctor performs the suturing operation, the positioning rod and the depth limiting sleeve approach the position to be sutured simultaneously, and then the positioning rod is used to press against the wound to be sutured. At this time, the distance between the depth limiting sleeve and the wound to be sutured is certain, which makes it easier for the doctor to suture the wound accurately, thereby improving the surgical effect to a certain extent.

[0024] Optionally, the limiting sleeve has a receiving cavity, and one end of the positioning rod is provided with a push block. The push block is slidably inserted into the receiving cavity, and the outer wall of the push block is in contact with the inner wall of the receiving cavity. The air tube is connected to the end of the receiving cavity near the positioning rod.

[0025] By adopting the above technical solution, when the elastic airbag is compressed, the gas stored in the elastic airbag can enter the receiving cavity through the trachea, which increases the gas pressure at the end of the receiving cavity near the positioning rod, thereby facilitating the movement of the push block. The push block drives the positioning rod to move, which in turn reduces the possibility of the positioning rod squeezing the tissue at the wound site and causing tissue damage when the doctor inserts the needle with the suture gun.

[0026] Optionally, the positioning component includes a second elastic element disposed within the receiving cavity, the second elastic element abutting against the inner wall of the receiving cavity and the side of the push block opposite to the positioning rod.

[0027] By adopting the above technical solution, when the elastic airbag is no longer compressed, the gas discharged into the accommodating cavity flows back into the elastic airbag. At this time, the second elastic element can push the push block to move, which helps the positioning rod to return to its original position.

[0028] Optionally, the lifting bracket includes a base and a lifting frame mounted on the base. The base is provided with casters on the side away from the lifting frame, and the support arm is located on the end of the lifting frame away from the base.

[0029] By adopting the above technical solution, the support arm is connected to the lifting frame, which makes it easy to adjust the height of the suture gun through the lifting frame, and the base is equipped with casters, which makes it easy to move the gun-type meniscus repair instrument.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. Through the cooperation of the lifting bracket, support arm, movable component, suture gun, positioning component and locking device, it is beneficial to reduce the possibility of hand soreness and numbness during long-term delicate operation without affecting the doctor's suturing operation. This can lead to suturing errors, making it easier for the doctor to suture the wound accurately and thus helping to improve the surgical effect.

[0032] 2. Through the cooperation of the support arm, slider, seal, rotating shaft and connecting parts, doctors can move the suture gun easily and flexibly, thereby improving the flexibility of doctors in using the suture gun;

[0033] 3. Through the cooperation of the elastic airbag, trachea, sealing components and connectors, after the doctor moves the suture gun to the corresponding position, the elastic airbag can be compressed to fix the position of the suture gun relative to the slider, which is conducive to the precise suturing of the wound.

[0034] 4. The positioning rod allows the doctor to accurately move the depth-limiting sleeve to the position to be sutured, thus facilitating precise suturing of the wound and improving the surgical outcome to some extent. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0041] This application discloses a gun-type meniscus repair device.

[0042] Reference Figure 1 The gun-type meniscus repair instrument includes a lifting support 1, a support arm 2, a suture gun 3, and a locking device 4. The support arm 2 is fixedly mounted on the lifting support 1, and a movable component 5 connects the support arm 2 and the suture gun 3. This allows the support arm 2 to support the suture gun 3, and the suture gun 3 can move relative to the support arm 2 via the movable component 5, facilitating position adjustment. The locking device 4 is connected to the movable component 5 and locks it in place, thus fixing the position of the suture gun 3 when it is moved to the appropriate position, making it easier for the surgeon to suture the wound.

[0043] Reference Figure 1 The lifting support 1 includes a base 11 and a lifting frame 12 mounted on the base 11, wherein a caster wheel 111 is fixedly connected to the side of the base 11 opposite to the lifting frame 12. Multiple caster wheels 111 are provided to facilitate the movement of the lifting support 1.

[0044] Reference Figure 1 The lifting frame 12 can be configured in various ways; in this embodiment, the lifting frame 12 is electrically operated. The end of the lifting frame 12 away from the base 11 is fixedly connected to the support arm 2, thereby facilitating the lifting and lowering of the support arm 2.

[0045] Reference Figure 1 and Figure 2 The end of the support arm 2 away from the lifting frame 12 is slidably connected to a slider 21, and a rotating groove 211 is provided on the slider 21. In this embodiment, the rotating groove 211 is a T-shaped groove, and the end of the rotating groove 211 with a smaller diameter is located on the side of the slider 21 away from the support arm 2.

[0046] Reference Figure 2In this embodiment, the active component 5 includes a seal 51, a connector 52, and a first elastic member 53. The seal 51 is rotatably connected to the slider 21, and the seal 51 can rotate about the axis of the rotating groove 211.

[0047] Reference Figure 2 The cross-section of the connection between the seal 51 and the slider 21 is T-shaped, which makes it difficult for the seal 51 to separate from the slider 21.

[0048] Reference Figure 1 and Figure 2 The end of the seal 51 away from the slider 21 is rotatably connected to a rotating shaft 511, and the axis of the rotating shaft 511 is perpendicular to the axis of the rotating groove 211. The sewing gun 3 is fixedly connected to the rotating shaft 511, so that the sewing gun 3 can rotate relative to the seal 51 through the rotating shaft 511.

[0049] Reference Figure 1 and Figure 2 The arrangement of slider 21, seal 51 and rotating shaft 511 ensures that while the support arm 2 supports the suture gun 3, the suture gun 3 can rotate flexibly relative to the support arm 2, thereby improving the flexibility of doctors in using the suture gun 3.

[0050] Reference Figure 2 The sealing member 51 has a sealed cavity 512, and both ends of the rotating shaft 511 are inserted into the sealed cavity 512. One end of the connecting member 52 is slidably inserted into the rotating groove 211, and the shape of the end of the connecting member 52 inserted into the rotating groove 211 is adapted to the setting of the rotating groove 211, so that the connecting member 52 can rotate around the axis of the rotating groove 211. The other end of the connecting member 52 is slidably inserted into the sealed cavity 512, and the outer wall of the connecting member 52 is in contact with the inner wall of the sealed cavity 512.

[0051] Reference Figure 2 In this embodiment, anti-slip textures 54 are provided on the inner wall of the rotating groove 211 near the seal 51, at both ends of the connector 52, and on the circumferential outer wall of the rotating shaft 511.

[0052] Reference Figure 1 and Figure 2 When the anti-slip texture 54 on the connector 52 comes into contact with the anti-slip texture 54 on the inner wall of the rotating groove 211, the friction between the connector 52 and the inner wall of the rotating groove 211 increases, making it difficult for the connector 52 to rotate around the axis of the rotating groove 211. This helps to reduce the possibility of the seal 51 and the sewing gun 3 rotating around the inner wall of the rotating groove 211.

[0053] Reference Figure 1 and Figure 2When the anti-slip texture 54 on the connector 52 comes into contact with the anti-slip texture 54 on the rotating shaft 511, the friction between the connector 52 and the rotating shaft 511 increases, making it difficult for the rotating shaft 511 to rotate. This helps to reduce the possibility of the sewing gun 3 rotating around the axis of the rotating shaft 511, and thus makes it easier to fix the position of the sewing gun 3 relative to the slider 21.

[0054] Reference Figure 1 and Figure 2 The first elastic element 53 can be configured in various ways. In this embodiment, the first elastic element 53 is a spring. The first elastic element 53 is disposed in the rotating groove 211 and sleeved on the connecting member 52. The first elastic element 53 can abut against the rotating groove 211 and the connecting member 52 respectively. At this time, the first elastic element 53 can apply a pushing force to the connecting member 52, so that the anti-slip texture 54 on the connecting member 52 is less likely to abut against the inner wall of the rotating groove 211 and the anti-slip texture 54 on the rotating shaft 511, thereby facilitating the adjustment of the position of the sewing gun 3 relative to the slider 21.

[0055] Reference Figure 1 and Figure 3 The suture gun 3 is equipped with a positioning component 6. In this embodiment, the positioning component 6 includes a limiting sleeve 61, a positioning rod 62, and a second elastic element 63. The limiting sleeve 61 is fitted onto the suture gun 3 and can be fixed in various ways.

[0056] Reference Figure 3 The limiting sleeve 61 has a sealed receiving cavity 611. One end of the positioning rod 62 is slidably inserted into the receiving cavity 611, and the end of the positioning rod 62 inserted into the receiving cavity 611 is fixedly connected to a push block 621. The outer wall of the push block 621 is in contact with the inner wall of the receiving cavity 611.

[0057] Reference Figure 3 The second elastic element 63 can be configured in various ways. In this embodiment, the second elastic element 63 is a spring. The second elastic element 63 is disposed in the receiving cavity 611, and the second elastic element 63 is located on the side of the push block 621 away from the positioning rod 62. The second elastic element 63 is in contact with the inner wall of the push block 621 and the receiving cavity 611, so that the second elastic element 63 can push the push block 621 to move.

[0058] Reference Figure 1 and Figure 3 The muzzle end of the suture gun 3 is equipped with a depth-limiting sleeve 31, and the end of the positioning rod 62 away from the push block 621 is set close to the depth-limiting sleeve 31. The distance between the positioning rod 62 and the depth-limiting sleeve 31 is adapted to the distance between the wound to be sutured and the position to be sutured.

[0059] Reference Figure 1 and Figure 3In this embodiment, two positioning rods 62 are provided, and the two positioning rods 62 are respectively fixedly connected to the push block 621. The distance between the two positioning rods 62 and the end of the depth limiting sleeve 31 away from the suture gun 3 is adapted to the distance between the wound to be sutured and the position to be sutured, so as to facilitate the use of the two positioning rods 62 to assist the depth limiting sleeve 31 in positioning, and thus facilitate the doctor to accurately move the depth limiting sleeve 31 to the position to be sutured.

[0060] Reference Figure 1 and Figure 2 In this embodiment, the locking device 4 includes an elastic airbag 41 and an air tube 42 communicating with the elastic airbag 41. The end of the air tube 42 furthest from the elastic airbag 41 is connected to the sealing cavity 512 and the receiving cavity 611 (see reference). Figure 3 The air pipe 42 is connected to the sealing cavity 512, and the connection between the air pipe 42 and the receiving cavity 611 is located near the positioning rod 62.

[0061] Reference Figure 1 and Figure 2 The elastic airbag 41 stores gas. When the elastic airbag 41 is compressed, the gas stored in the elastic airbag 41 can flow into the sealing cavity 512 through the air tube 42, which increases the gas pressure in the sealing cavity 512 on the side of the connector 52 near the slider 21, thereby pushing the connector 52 to move. At this time, the first elastic element 53 is compressed, and the anti-slip texture 54 on the connector 52 abuts against the inner wall of the rotating groove 211 and the anti-slip texture 54 on the rotating shaft 511, thereby achieving the purpose of fixing the position of the sewing gun 3 relative to the slider 21.

[0062] Reference Figure 1 and Figure 3 Meanwhile, the gas stored in the elastic airbag 41 can also flow into the receiving cavity 611 through the trachea 42, which increases the gas pressure on the side of the receiving cavity 611 near the positioning rod 62, thereby facilitating the movement of the push block 621. At this time, the second elastic element 63 is compressed, and the push block 621 drives the positioning rod 62 to move, which helps to reduce the possibility that the positioning rod 62 will not easily squeeze the tissue at the wound site and cause damage when the doctor operates the limiting sleeve 61 tube into the tissue at the wound site.

[0063] Reference Figure 1 and Figure 2 When the elastic airbag 41 is no longer compressed, the sealing cavity 512 and the receiving cavity 611 (see reference) Figure 3 The gas inside the first elastic element 53 flows back into the elastic airbag 41, causing the first elastic element 53 and the second elastic element 63 (see reference) to... Figure 3 Upon rebound, the first elastic element 53 pushes the connector 52 back to its original position, thus making the position of the suture gun 3 relative to the slider 21 no longer fixed, facilitating the doctor to perform suturing operations again. Simultaneously, the second elastic element 63 (refer to...) Figure 3) can drive push block 621 (refer to Figure 3 The positioning rod 62 returns to its original position.

[0064] The implementation principle of a gun-type meniscus repair instrument according to this application embodiment is as follows: When it is necessary to suture a wound on the meniscus using a suture gun 3, the repair instrument is first moved to the designated position, and the position of the suture gun 3 is adjusted by the lifting frame 12. Then, the doctor holds the suture gun 3 and moves the depth-limiting cannula 31 to a position close to the wound.

[0065] Next, the positioning rod 62 is pressed against the wound tissue to fix the distance between the depth limiting sleeve 31 and the wound. Then, pressure is applied to the elastic airbag 41 to fix the position of the suture gun 3 relative to the slider 21 and to move the positioning rod 62 away from the depth limiting sleeve 31.

[0066] Then, a thrust is applied to the suture gun 3, causing the depth-limiting cannula 31 to pass through the wound tissue and reach the tissue surface. The trigger of the suture gun 3 is then pressed, causing the suture inside the depth-limiting cannula 31 to be pushed out. After pushing the depth-limiting cannula 31 out of the wound tissue, pressure on the elastic airbag 41 is stopped, fixing the position of the suture gun 3 relative to the slider 21 and causing the positioning rod 62 to return to its original position. At this point, the positioning rod 62 is offset from the suture to reduce interference with subsequent suturing operations.

[0067] Finally, select a suitable location and repeat the above steps to complete the suturing of the wound on the meniscus.

[0068] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
