Description

Technical Field

[0001] This utility model relates to the field of suture technology, and in particular to a neurosurgical micro-precision suture device. Background Technology

[0002] Neurosurgical micro-suturing devices are primarily used for suturing mucosa, dura mater, and spinal dura mater within narrow, tubular channels of approximately 1 cm. Skull base reconstruction following transnasal resection of sellar region tumors in neurosurgery requires suturing the mucosa or dura mater within narrow, tubular channels. Similar procedures are performed during dura mater suturing in spinal cord surgery under a microscope.

[0003] In similar operations, there are no dedicated suturing instruments. In addition, due to the limited operating space, the traditional suturing method has insufficient space for turning and exiting the needle, making the operation difficult. Furthermore, the traditional needles do not have a length adjustment mechanism, which leads to the needles being too long or too short during use. Therefore, the instrument needs to be improved in terms of tools and suturing methods. Utility Model Content

[0004] The purpose of this invention is to solve the problems of insufficient operating space for needle rotation and needle exit in existing technologies and the lack of length adjustment mechanisms, and to propose a neurosurgical micro-precision suture device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a neurosurgical micro-precision suture device, comprising a forceps body and a suture needle body. The bottom outer wall of the suture needle body is uniformly perforated with insertion holes. A connecting sleeve is slidably connected to the bottom outer wall of the suture needle body. A C-shaped frame is fixedly installed on the top outer wall of the connecting sleeve. A sliding hole is formed on one side of the C-shaped frame and the top outer wall of the connecting sleeve. An insertion post is slidably connected inside the sliding hole. A fixing ring is fixedly installed on the outer wall of the insertion post. A spring is sleeved on the outer wall of the insertion post. A connecting block is fixedly installed at the end of the insertion post away from the sliding hole.

[0006] Preferably, anti-slip rings are uniformly fixedly installed on the outer wall of the connecting block.

[0007] Preferably, the inner wall of the connecting sleeve is symmetrically provided with limiting grooves, and the bottom outer wall of the needle body is symmetrically provided with limiting strips, and the limiting strips are slidably connected to the limiting grooves.

[0008] Preferably, the insertion post and the insertion hole are slidably connected.

[0009] Preferably, one end of the spring is fixedly connected to the fixing ring, and the other end of the spring is fixedly connected to the C-shaped frame.

[0010] Preferably, a fixing plate is fixedly installed on one side of the tweezers body, a reserved hole is opened through the surface of the fixing plate, a screw hole is opened through the side of the fixing plate away from the tweezers body, a bolt is threaded into the screw hole, and a knob is fixedly installed at the end of the bolt away from the screw hole.

[0011] Preferably, a soft pad is fixedly installed at the end of the bolt away from the knob.

[0012] Preferably, the reserved hole and the connecting sleeve are slidably connected.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by pulling the connecting block, the insertion post slides inside the sliding hole. During the sliding process, the insertion post will move the fixing ring together. During the movement, the fixing ring will squeeze the spring towards the inside of the C-shaped frame. After being squeezed to a certain extent, the insertion post will move away from the insertion hole. After moving away, the suture body can be pulled up or down to make it slide inside the connecting sleeve. After sliding a suitable distance, the connecting block can be released. After releasing, the spring's rebound force will push the insertion post into another insertion hole. This design realizes the length adjustment function of the suture body, thus adapting it to the usage needs of different medical staff and effectively avoiding the suture body being too long or too short during use.

[0015] 2. In this utility model, the tweezers body and the suture needle body are disinfected. After disinfection, the connecting sleeve on the outer wall of the suture needle body is inserted into the reserved hole. After inserting it a certain distance, the knob is turned. The knob drives the bolt to rotate inside the screw hole. After rotating a certain number of times, the bolt will press against the connecting sleeve with the soft pad, thereby limiting the connecting sleeve. This design realizes the integrated storage of the tweezers body and the suture needle body, effectively preventing the tweezers body and the suture needle body from being easily lost when stored separately.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figures 1-3 As shown, this utility model provides a technical solution: a neurosurgical micro-precision suture device, including a forceps body 1 and a suture needle body 2. Insertion holes 3 are evenly distributed through the bottom outer wall of the suture needle body 2. A connecting sleeve 4 is slidably connected to the bottom outer wall of the suture needle body 2. A C-shaped frame 5 is fixedly installed on the top outer wall of the connecting sleeve 4. A sliding hole 6 is formed on one side of the C-shaped frame 5 and the top outer wall of the connecting sleeve 4. An insertion post 7 is slidably connected inside the sliding hole 6. A fixing ring 8 is fixedly installed on the outer wall of the insertion post 7. A spring 9 is sleeved on the outer wall of the insertion post 7. The insertion post 7 is located away from the sliding hole 6. A connecting block 10 is fixedly installed at the end. Anti-slip rings 11 are evenly fixedly installed on the outer wall of the connecting block 10. Limiting grooves 12 are symmetrically opened on the inner wall of the connecting sleeve 4. Limiting strips 13 are symmetrically installed on the bottom outer wall of the needle body 2. The needle body 2 is inserted into the two limiting strips 13, so that the needle body 2 can be replaced after wear. The limiting strips 13 and the limiting grooves 12 are slidably connected. The insertion post 7 is slidably connected to the insertion hole 3. One end of the spring 9 is fixedly connected to the fixing ring 8, and the other end of the spring 9 is fixedly connected to the C-shaped frame 5.

[0025] In this embodiment, by pulling the connecting block 10, the insertion post 7 is moved to slide inside the sliding hole 6. During the sliding process, the insertion post 7 will move the fixing ring 8 together. During the movement, the fixing ring 8 will press the spring 9 towards the inside of the C-shaped frame 5. After being pressed to a certain extent, the insertion post 7 will move away from the insertion hole 3. After moving away, the needle body 2 will be pulled up or down, so that the needle body 2 will slide inside the connecting sleeve 4. After sliding a suitable distance, the connecting block 10 will be released. After being released, the rebound force of the spring 9 will push the insertion post 7 into another insertion hole 3. This design realizes the length adjustment function of the needle body 2, thereby adapting it to the usage needs of different medical staff and effectively avoiding the needle body 2 being too long or too short during use.

[0026] Example 2: As Figures 4-5 As shown, the difference between this embodiment and embodiment 1 is only that a fixing plate 14 is fixedly installed on one side of the tweezers body 1, a reserved hole 15 is opened through the surface of the fixing plate 14, a screw hole 16 is opened through the side of the fixing plate 14 away from the tweezers body 1, a bolt 17 is threaded inside the screw hole 16, a knob 18 is fixedly installed at the end of the bolt 17 away from the screw hole 16, a soft pad 19 is fixedly installed at the end of the bolt 17 away from the knob 18, and the reserved hole 15 is slidably connected to the connecting sleeve 4.

[0027] In this embodiment, the tweezers body 1 and the needle body 2 are disinfected. After disinfection, the connecting sleeve 4 on the outer wall of the needle body 2 is inserted into the reserved hole 15. After inserting it a certain distance, the knob 18 is turned. The knob 18 drives the bolt 17 to rotate inside the screw hole 16. After rotating a certain number of times, the bolt 17 will press against the connecting sleeve 4 with the soft pad 19, thereby limiting the connecting sleeve 4. This design realizes the integrated storage of the tweezers body 1 and the needle body 2, effectively preventing the tweezers body 1 and the needle body 2 from being easily lost when stored separately.

[0028] The working principle of this embodiment is as follows: During operation, the tweezers body 1 and the needle body 2 are first disinfected. After disinfection, the suture required for suturing is passed through the suture hole of the needle body 2. After passing through, the needle body 2 is used to pierce the mucosa. After piercing, the suture on the needle body 2 will pass through the mucosa. After passing through, the tweezers body 1 is used to pull the suture. By repeatedly threading and pulling the suture, the mucosa is finely sutured. At the same time, since it is not necessary to completely withdraw and rotate the needle, suturing can be performed in a space of 1cm or even smaller, which simplifies the operation process. When the length of the suture needle body 2 is too long or too short, the connecting block 10 can be pulled, which will cause the insertion post 7 to slide inside the sliding hole 6. During the sliding process, the insertion post 7 will move the fixing ring 8 together. During the movement, the fixing ring 8 will squeeze the spring 9 towards the inside of the C-shaped frame 5. After being squeezed to a certain extent, the insertion post 7 will move away from the insertion hole 3. After moving away, pull the suture needle body 2 up or down to make it slide inside the connecting sleeve 4. After sliding a suitable distance, release the connecting block 10. After releasing, the rebound force of the spring 9 will push the insertion post 7 into another insertion hole 3. This design realizes the length adjustment function of the suture needle body 2, thereby adapting it to the usage needs of different medical staff and effectively avoiding the suture needle body 2 being too long or too short during use. After suturing is completed, the tweezers body 1 and the needle body 2 are first disinfected. After disinfection, the connecting sleeve 4 on the outer wall of the needle body 2 is inserted into the reserved hole 15. After inserting it a certain distance, the knob 18 is turned. The knob 18 drives the bolt 17 to rotate inside the screw hole 16. After rotating a certain number of times, the bolt 17 will press against the connecting sleeve 4 with the soft pad 19, thereby limiting the connecting sleeve 4. This design realizes the integrated storage of the tweezers body 1 and the needle body 2, effectively preventing the tweezers body 1 and the needle body 2 from being easily lost when stored separately.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
