Description

Technical Field

[0001] The utility model relates to the technical field of suturing devices, in particular to a suturing device. Background Art

[0002] When medical staff use the suture needle to perform three-leaf suture, they first suture the trimmed edge points in the center position. After fixing and closing the dura mater, a very vivid "three-leaf clover" pattern appears. This is the "three-leaf clover" dura mater in situ strict suture method.

[0003] For example, in the Chinese patent document with the announcement number CN204655022U, a handle is provided, a notch is provided on the handle, and a slide groove is connected to the notch, a seal is placed in the slide groove, a curved needle is vertically fixedly connected to the top of the side of the handle, and a lead hole is provided on the curved needle. The suture device provided by the technical solution is suitable for surgical suture in various situations. When there is a suture needle, the suture needle can be clamped for surgical suture. When there is no suture needle, the curved needle can be directly used for threading and suture.

[0004] However, the suture needle in the above technical solution is always exposed to the outside world, which is easy to accidentally injure medical staff and takes up space, making it inconvenient to carry. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a suturing instrument, which can store movably connected suture needles through the provision of a storage groove, thereby preventing the exposed suture needles from injuring medical staff and occupying space and being inconvenient to carry. Moreover, because the cross-section of the connecting groove and the cross-section of the positioning plate are both set to be rectangular, the connecting groove and the positioning groove are still matched with the positioning groove after the suture needle is unfolded or stored. Therefore, the positioning plate can be embedded in the connecting groove through the threaded connection of the fixing plate and the mounting groove, and then the suture needle after storage can be limited and fixed by the clamping of the positioning plate, the positioning groove and the connecting groove, thereby ensuring the stability of the suture needle when it is unfolded or stored, so as to solve the problems arising from the above-mentioned background technology.

[0024] Refer to the instruction manual Figure 1-5 , the utility model provides a suturing device, comprising a mounting plate 1, wherein the mounting plate 1 is provided with a suturing assembly for three-leaf suturing;

[0025] like Figure 1-3 As shown, the suturing assembly includes a receiving slot 9, which is opened on one side of the mounting plate 1, and a support column 10 is provided inside the rear end of the receiving slot 9, and a fixing column 11 is installed at the top and bottom of the supporting column 10, and a fixing slot 12 is opened on the side of the mounting plate 1 close to the fixing column 11, and the fixing column 11 extends to the inside of the fixing slot 12 at one end away from the supporting column 10, and a suturing needle 13 is installed on the side of the supporting column 10 away from the receiving slot 9; a connecting slot 14 is opened at the top of the fixing column 11 located at the top of the supporting column 10, and the bottom end of the positioning plate 4 extends to the inside of the connecting slot 14. The setting of the suturing needle 13 facilitates the medical staff to perform the three-leaf suturing operation, and at the same time, with the help of the setting of the receiving slot 9, the suturing needle 13 can be easily stored to avoid the suturing needle 13 being exposed and stabbing the medical staff and occupying space and being inconvenient to carry.

[0026] In order to facilitate the storage and adjustment of the suture needle 13, a positioning assembly for fixing the suture assembly is provided on the outside of the mounting plate 1;

[0027] like Figure 1 , 3 As shown in , 4 and 5, the positioning assembly includes a positioning groove 2 and a mounting groove 3 which are connected to each other. The mounting groove 3 is located above the positioning groove 2. The positioning groove 2 and the mounting groove 3 are both opened at the top of the rear end of the mounting plate 1. A positioning plate 4 is provided inside the positioning groove 2. A movable cavity 5 is opened inside the positioning plate 4. A movable plate 6 is provided inside the movable cavity 5. A movable column 7 is installed on the top of the movable plate 6. The top of the movable column 7 passes through the positioning plate 4 and extends to the inside of the mounting groove 3. A fixing plate 8 is provided inside the mounting groove 3. The outer wall of the fixing plate 8 is threadedly connected to the inner wall of the mounting groove 3. The top of the movable column 7 is connected to the bottom of the fixing plate 8.

[0028] like Figure 4 and 5As shown, the cross-section of the positioning plate 4 and the cross-section of the connecting groove 14 are both set to be rectangular, and the outer wall of the positioning plate 4 is in contact with the inner wall of the connecting groove 14. By setting the cross-section of the positioning plate 4 and the cross-section of the connecting groove 14 to be rectangular, the positioning plate 4 can limit and fix the fixing column 11 to prevent the fixing column 11 from rotating, thereby ensuring the stability of the fixing column 11.

[0029] like Figure 1 and 2 As shown, a protective sleeve 15 is sleeved on the outside of the rear end of the mounting plate 1, and the protective sleeve 15 is made of rubber material. The provision of the protective sleeve 15 can improve the safety of medical staff when holding the utility model. A plurality of anti-slip strips 16 are installed on the top and bottom of the front end of the protective sleeve 15, and the plurality of anti-slip strips 16 are evenly spaced and distributed. The provision of the plurality of anti-slip strips 16 can enhance the friction between the medical staff's hands and the protective sleeve 15, thereby enhancing the stability of the medical staff when operating the utility model.

[0030] like Figure 1 and 2 As shown, a fixed bracket 17 is installed at the rear end of the mounting plate 1, and a pressure plate 18 is arranged inside the fixed bracket 17. A screw 19 is arranged at the rear end of the pressure plate 18. The front end of the screw 19 is movably connected with the pressure plate 18 through a bearing, and the rear end of the screw 19 penetrates the fixed bracket 17 and extends to the rear side of the fixed bracket 17. The screw 19 is threadedly connected to the fixed bracket 17. Through the threaded connection between the screw 19 and the fixed bracket 17, medical staff can rotate the screw 19 to adjust the orientation of the pressure plate 18, so as to fix a specific suturing device, thereby improving the practicality of the utility model.

[0031] The provision of the suture needle 13 makes it convenient for medical personnel to perform the three-leaf suture operation. At the same time, in order to improve the convenience of medical personnel in storing the suture needle 13 and avoid the exposed suture needle 13 from stabbing the medical personnel and occupying space, the fixing plate 8 can be rotated to drive the positioning plate 4 to separate from the fixing column 11, so that the support column 10 can be unrestricted and it is convenient for medical personnel to store the suture needle 13 into the storage groove 9. Because the cross-section of the connecting groove 14 and the cross-section of the positioning plate 4 are both set to be rectangular, the connecting groove 14 after rotating with the support column 10 is still matched with the positioning groove 2, and then the fixing plate 8 can be connected with the mounting groove 3 by thread, and the positioning plate 4 can be embedded into the connecting groove 14, and then the suture needle 13 after storage can be limited and fixed by the clamping of the positioning plate 4, the positioning groove 2 and the connecting groove 14.
