[0002] The temporomandibular joint is also called the "temporomandibular joint" or "mandibular joint". It is composed of the mandibular head, the mandibular fossa of the temporal bone and the articular tubercle. The left and right sides form a joint joint that is responsible for opening and closing the mouth and chewing. The joint capsule is loose, and the sides are reinforced by the medial and lateral ligaments. The articular disc in the capsule is oval, composed of fibrocartilage, and is divided into three parts: front, middle and back. The upper side is saddle-shaped, concave in front and convex in the back, corresponding to the convex and concave contours of the articular tubercle and the mandibular fossa; the lower side is concave facing the mandibular head, the periphery is connected to the joint capsule, and the front edge is connected to the lateral pterygoid tendon that passes through the joint capsule. The articular disc divides the joint cavity into upper and lower halves.

[0003] The articular disc of the skull is located at the junction of the mandible and the temporal bone. The articular disc is composed of fibrous cartilage in the joint capsule. The disc is oval in shape, with a saddle-shaped upper surface that is concave in front and convex in the back, corresponding to the shape of the articular tubercle and the mandibular fossa. During general temporomandibular disc reduction surgery, the doctor needs to hold a needle and thread to suture and fix the articular disc. Threading and hooking the thread during suturing are very difficult. Operational errors can cause damage to the temporomandibular disc, which will cause permanent sequelae to the patient's daily life. Therefore, a safer operating device is needed.

[0049] In this embodiment, the fixing bolt 19 is rotated to loosen the rotating cylinder 24, and then the lifting knob 18 is rotated to rotate the lifting knob 18 and the rotating cylinder 24 together by 90 degrees, so that the arc fillet 42 is located on one side of the articular disc, the fixing bolt 19 is rotated to fix the position of the rotating cylinder 24, and then the lifting rod 23 is slid downward to allow the lifting plate 22 and the positioning plate 21 to slide relative to each other. At this time, the suture needle 26 passes through the second hole on the articular disc, and the suture needle 26 passes through the positioning ring 25. Due to the angle design of the positioning ring 25, the position of the suture needle 26 is adjusted to facilitate the second threading of the suture needle 26 on the same side of the articular disc.

[0050] Reference Figure 1 , Figure 2 , Figure 7 and Figure 8In a preferred embodiment, the thread loosening mechanism includes a fixed baffle 27 fixedly connected to the inner side of the lifting plate 22, a reset spring 28 is fixedly connected to the bottom of the fixed baffle 27, a rotating slide rail 29 is rotatably connected to the inner side of the lifting plate 22, a matching mechanism is installed at the bottom of the rotating slide rail 29, and the matching mechanism is used to lock the thread on the suture needle 26 during surgery, the matching mechanism includes a sliding groove opened at the bottom of the rotating slide rail 29, a slider 35 is slidably connected inside the sliding groove, a sliding spring 30 is fixedly connected to one side of the slider 35, a thread locking mechanism is installed at the bottom of the slider 35, and the thread locking mechanism is used to lock the thread, and the thread locking mechanism includes a fixed shaft 32 fixedly connected to the bottom of the slider 35, one end of the fixed shaft 32 is rotatably connected to the second thread clamp 34, one end of the fixed shaft 32 is located at the bottom of the second thread clamp 34 and is rotatably connected to the first thread clamp 33, and the first thread clamp 33 One end of the wire tensioning spring 31 is fixedly connected to the wire tensioning rod 41, the other end of the first wire tensioning clamp 33 is fixedly connected to the first wire tensioning rod 41, and one end of the second wire tensioning clamp 34 is fixedly connected to the second wire tensioning rod 43. One end of the first wire tensioning rod 41 and the second wire tensioning rod 43 are respectively provided with an arc fillet 42. The other end of the return spring 28 is fixedly connected to the upper surface of the rotating slide rail 29. The position of the rotational connection between the rotating slide rail 29 and the lifting plate 22 is on one side of the return spring 28. The return spring 28 is in a relaxed state, and the rotating slide rail 29 is in a horizontal position. The other end of the wire tensioning spring 31 is fixedly connected to one end of the second wire tensioning clamp 34. The outer sides of one end of the first wire tensioning clamp 33 and the second wire clamp 34 close to the wire tensioning spring 31 are respectively in contact with the positioning plates 21 on both sides, and the wire tensioning spring 31 is in a compressed state. Therefore, the positioning plates 21 on both sides make the first wire clamp 33 and the second wire clamp 34 in a clamped state.

[0051] In this embodiment, when hanging the thread, after the suture needle 26 passes through the positioning ring 25, the tip of the suture needle 26 will press against the arc fillet 42, so that the slider 35 slides to one side on the rotating slide rail 29 to compress the sliding spring 30 until the arc fillet 42 slides into the thread hanging groove 37. At this time, the first thread rod 41 and the second thread rod 43 hook the positioning thread 16, and the suture needle 26 is pulled out.

When hooking the thread, since the thread tensioning spring 31 is in a compressed state, the positioning plates 21 on both sides make the first thread clamp 33 and the second thread clamp 34 in a clamped state. When the suture needle 26 is in the state of being moved along the suture line 14, the suture line 14 will move along the suture line 14 and the suture line 14 will move along the suture line 14.

[0052] Working principle: When in use, after the patient is anesthetized, loosen the mounting belt 9 on the Japanese buckle 8 and put the mounting belt 9 on the patient's neck. At this time, there is no need to tighten the mounting belt 9. Just place the base 1 next to the cheek of the patient on the side that needs surgery to expose the temporomandibular joint, fix a short nail at the condyle of the temporomandibular joint, fix one end of the suture needle 26 on the short nail, cut the articular disc from the muscle, and loosen the articular disc. By tightening the mounting belt 9, place the base 1 next to the cheek of the patient on the side that needs surgery. The material of the first sponge pad 10 and the second sponge pad 11 is soft, so that the arc design on one side of the base 1 can fit the patient's face well. Hold the handle 2 with the right hand, slide on the rotating block, and the rotating block rotates on the rotating seat 4. The seat 4 can rotate on the base 1 to achieve flexible pointing of the suture needle 26. By adjusting the position of the suture needle 26, the needle tip 38 on the suture needle 26 is used to thread the loosened fixed disk. Since the positioning line 16 passes through the wire hole and the sliding hole 36 on the wire rod 3, and then the positioning line 16 passes through the return hole 39, when threading the joint disc, the positioning line 16 follows the suture needle 26 to pass through the joint disc. By rotating the front and back adjustment knob 13, the position of the adjustment cylinder 6 is moved back and forth to adjust the front and back position of the adjustment cylinder 6. By moving the left and right adjustment knob 7, the left and right position of the sliding rod 14 is adjusted, so that the positioning ring 25 on the first fixed rod 15 is located on one side of the joint disc, which has the effect of flexibly adjusting the position of the positioning ring 25, and is convenient for coordinating the suturing process of the suture needle 26. , pass the suture needle 26 through the positioning ring 25. Due to the angle design of the positioning ring 25, after the suture needle 26 passes through the positioning ring 25, the tip of the suture needle 26 will press against the arc fillet 42, so that the slider 35 slides to one side on the rotating slide rail 29 to compress the sliding spring 30 until the arc fillet 42 slides into the hanging wire groove 37. At this time, the first wire rod 41 and the second wire rod 43 hook the positioning wire 16, and the suture needle 26 is pulled out. Due to the arc design of the arc fillet 42, the arc fillet 42 will hook the positioning wire 16. Through this design, the hooking line can be automatically completed, which speeds up the progress of the operation and simplifies the surgical process. By adjusting the position of the suture needle 26, the suture needle 26 is threaded for the second time on the same side of the articular disc. At this time, the fixing bolt 19 is rotated to rotate the cylinder 2 4 is loosened, and then the lifting knob 18 is turned to rotate the lifting knob 18 and the rotating cylinder 24 together by 90 degrees, so that the arc fillet 42 is located on one side of the articular disc, and the fixing bolt 19 is turned to fix the position of the rotating cylinder 24, and then the lifting rod 23 is slid downward to make the lifting plate 22 and the positioning plate 21 slide relative to each other. Since the tensioning spring 31 is in a compressed state, the positioning plates 21 on both sides make the first wire clamp 33 and the second wire clamp 34 in a clamped state. When the first wire clamp 33 and the second wire clamp 34 slide out of the range of the positioning plate 21, the tensioning spring 31 makes the first wire clamp 33 and the second wire clamp 34 rotate relative to each other, and the first wire rod 41 and the second wire rod 43 make the positioning wire 16 open, and one end of the positioning wire 16 is on the first wire rod 41.The other end is on the second wire rod 43, which plays the role of placing the positioning wire 16 horizontally on the first wire rod 41 and the second wire rod 43, which is convenient for subsequent hooking operation. At this time, the suture needle 26 passes through the second hole on the joint disc, passes through the positioning ring 25 through the suture needle 26, and uses the hook wire groove 40 at one end of the suture needle 26 to hook the positioning wire 16 of the first wire rod 41 and the second wire rod 43, and withdraws the suture needle 26. By tightening the positioning wire 16, the position of the joint disc is adjusted to restore the dislocated joint disc to its normal position. This hooking method makes the suture operation on the joint disc safer and more reliable. Tighten the positioning wire 16 and then fix the remaining end of the positioning wire 16 with the short nail, suture the wound, and complete the operation.
