Description

Technical Field

[0001] This utility model relates to the field of medical surgical instruments, specifically a tissue fixator for locating the spinal cord region. Background Technology

[0002] Spinal surgery aims to treat spinal diseases such as herniated discs, scoliosis, spinal fractures, and tumors. Due to the complexity and importance of the spinal structure, the surgery requires extremely high precision and stability. Any minor error can lead to serious complications or even permanent nerve damage. In spinal surgery, tissue fixation is a crucial step in ensuring surgical success; tissue fixators that can locate the spinal cord region are auxiliary tools used in medical research and surgery.

[0003] However, current tissue locators are mainly for fixation and do not have the ability to locate the spinal cord region. Locating the spinal cord region is a crucial step in spinal surgery to ensure the accuracy and safety of the operation. Current positioning methods generally include: 1. Imaging examination; 2. Intraoperative imaging; 3. Electrophysiological monitoring; 4. Anatomical landmarks; 5. Ultrasound imaging; 6. Optical imaging technology, etc. However, these methods require the doctor to keep staring at the screen during the operation, which is cumbersome and mentally taxing. If a locator could be used to mark the location of the spinal cord, the location could be determined more quickly during surgery, reducing the surgeon's workload, improving the efficiency of the operation, and thus reducing the patient's stress.

[0004] Based on this, a tissue fixation device that can locate the spinal cord region is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide a tissue fixation device that can locate the spinal cord region, so as to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A tissue fixator for locating a spinal cord region includes a support component, a positioning component disposed in the center of the support component, and a plurality of fixation components disposed around the support component.

[0008] The positioning component includes a positioning ring, two movable collars are symmetrically fixedly connected to one side of the positioning ring, a buckle assembly is provided on the other side of the positioning ring, a rotating shaft is rotatably connected to the middle of one side of the positioning ring, a straight rod is fixedly connected to one side of the middle of the rotating shaft, and a puncture positioning ring is fixedly connected to the end of the straight rod away from the positioning ring.

[0009] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0010] In one alternative embodiment: the support assembly includes connecting rods, and a total of four connecting rods are provided. Two adjacent connecting rods are provided with connecting hinge seats at their adjacent ends and are hinged together through the connecting hinge seats. Two more distant connecting rods are provided with fixing rods at the same end and are fixedly connected to each other through the fixing rods.

[0011] In one alternative: each of the movable collars is slidably connected to the adjacent connecting rod.

[0012] In one alternative embodiment: the buckle assembly includes a buckle collar, which is fixedly connected to one side of a positioning ring. A spring buckle is provided on the inner side of the buckle collar. The buckle collar is slidably connected to an adjacent connecting rod. Several limiting grooves are formed on the surface of the connecting rod adjacent to the buckle collar, and the limiting grooves are buckled by the spring buckles.

[0013] In one alternative: the fixing component includes an adjusting rod, the surface of which is provided with a plurality of first through holes, a fixing pin is slidably disposed inside the first through holes, and a rotating hinge seat is fixedly connected to the lower end of the adjusting rod.

[0014] In one alternative: a fixed clamping plate is hinged to the lower end of the rotary hinge seat.

[0015] In one alternative: each of the fixed rods has a plurality of second through holes longitudinally extending through both ends, and the second through holes are slidably connected to the adjacent adjusting rods.

[0016] In one alternative: each of the fixing rods has several fixing holes laterally opened at both ends, the fixing holes being opened in correspondence with the first through hole, and the fixing pin being disposed through the interior of the adjacent first through hole and fixing hole.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model, through its positioning component, allows for the positioning of the spinal cord after the support component is fixed above the designated spine. The location is first determined via imaging examination, then the entire positioning ring is moved along the connecting rod to the designated spinal cord position. The positioning ring is then secured by a snap-fit ​​component on the snap-fit ​​ring, thus completing the positioning of the spinal cord and facilitating subsequent surgical procedures. If a puncture procedure is required, the puncture positioning ring can be rotated to the inside of the positioning ring via a rotating shaft, facilitating the restriction of surgical instruments used for puncture. This effectively improves surgical efficiency, reduces the burden on the surgeon, accelerates the surgical process, effectively improves surgical precision, and reduces patient pain and physical burden.

[0019] 2. This utility model uses a fixed component to quickly position the support component above the spine. The height-adjustable rods and fixing pins facilitate the fixation of the splint to the human tissue. Even at different positions, the position and height of the support component can be ensured by adjusting the height of each adjusting rod, which facilitates the positioning of the spinal cord and the operation of the surgeon, further improving the efficiency of the operation and enhancing the effectiveness and practicality of the device.

Two more distant connecting rods 1 are provided with fixing rods 3 at the same end and are fixedly connected to each other through the fixing rods 3. Folding the connecting rods 1 can reduce the volume and facilitate the insertion of this device into the patient's body.

[0030] In one embodiment, such as Figure 1 As shown, each of the movable collars 13 is slidably connected to the adjacent connecting rod 1, which facilitates the sliding limit of the positioning ring 12.

[0031] In one embodiment, such as Figure 2 and Figure 4 As shown, the buckle assembly includes a buckle collar 14, which is fixedly connected to one side of the positioning ring 12. A spring buckle 15 is provided on the inner side of the buckle collar 14. The buckle collar 14 is slidably connected to the adjacent connecting rod 1. Several limiting grooves 4 are opened on the surface of the adjacent connecting rod 1 of the buckle collar 14. The limiting grooves 4 are buckled and connected to the spring buckles 15. The spring buckles 15 will be limited and connected with the corresponding limiting grooves 4. The springs inside can slide into the buckle collar 14 when the positioning ring 12 is pushed to facilitate the movement of the positioning ring 12. After the positioning ring 12 moves to the designated position, the spring buckles 15 will slide into the adjacent limiting grooves 4 to complete the relative fixation of the positioning ring 12.

[0035] In one embodiment, such as Figure 2 and Figure 3 As shown, each of the fixing rods 3 has several fixing holes 6 horizontally opened at both ends. The fixing holes 6 are opened in correspondence with the first through holes 9. The fixing pins 8 are inserted through the adjacent first through holes 9 and fixing holes 6. In use, the position of the spinal cord is first located by imaging examination, and then the fixing splint 11 is fixed in the appropriate position. Then the connection height of the adjusting rod 7 and the fixing rod 3 is adjusted. Finally, the fixing pins 8 are inserted through the corresponding first through holes 9 and fixing holes 6 to fix the entire fixing rod 3 to the corresponding adjusting rod 7.

[0036] The above embodiments disclose a tissue fixator for locating the spinal cord region. In use, the location of the spinal cord is first determined through imaging examination. Then, the fixation splint 11 is fixed in the appropriate position. Next, the connection height between the adjusting rod 7 and the fixing rod 3 is adjusted. Then, the fixing pin 8 passes through the corresponding first through hole 9 and fixing hole 6 to fix the entire fixing rod 3 to the corresponding adjusting rod 7, thereby fixing the entire support assembly. After the fixation assembly is fixed, the position is further confirmed through imaging examination, and then the positioning is initiated. When the positioning ring 12 moves, the spring clip 15 will be connected to the corresponding limiting groove 4 for limiting. The spring clip 15 can slide into the clip sleeve 14 when the positioning ring 12 is pushed to facilitate the movement of the positioning ring 12. After the positioning ring 12 moves to the designated position, the spring clip 15 will slide into the adjacent limiting groove 4 to complete the relative fixation of the positioning ring 12. If puncture surgery is required, the puncture positioning ring 18 can be rotated to the inside of the positioning ring 12 through the rotating shaft 16 to facilitate the limiting of the puncture surgical instruments.
