[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 joints are mainly responsible for opening, closing and chewing. The articular disc divides the joint cavity into upper and lower halves. If there is a problem with the joint, conservative treatment is the first choice in most cases, and injection of lubricants is the first choice in conservative treatment. The injection depends entirely on the doctor's experience, and it is easy to make mistakes during the injection process. Repeated punctures will cause unnecessary damage.

[0003] In the prior art, a patent document with announcement number CN211512961U discloses a temporomandibular joint injection guide, and simultaneously discloses that the temporomandibular joint injection guide includes a fixing frame and a guide plate, the guide plate is connected to the fixing frame, the fixing frame is used to be mounted on the patient's head to fix the guide plate, and the guide plate is provided with a first guide hole and a second guide hole, the position of the first guide hole corresponds to the position of the upper joint cavity, and the position of the second guide hole corresponds to the position of the lower joint cavity. The temporomandibular joint injection guide of the utility model embodiment fixes the guide plate by mounting the fixing frame on the patient's head; however, in actual application, when determining the needle entry point for injection into the upper temporomandibular joint cavity, the prior art is to draw lines on the face with a water-based pen to make marking points. There is no auxiliary marking tool. The disadvantage of facial marking is low efficiency. Utility Model Content

[0016] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same components are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom" and "top", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0017] Example: See Figure 1-2The utility model provides a technical solution: a temporomandibular joint superior cavity injection marking ruler, comprising a first marking ruler 1 and a second marking ruler 2, the first marking ruler 1 is a hard ruler, the second marking ruler 2 is a soft ruler, one end of the first marking ruler 1 is hinged to one end of the second marking ruler 2, the first marking ruler 1 is connected with a marking head 4 through a driving component 3, firstly, a connecting block 12 of the first marking ruler 1 is placed between the tragus, and then a marking line 13 on an end of the second marking ruler 2 away from the hinged part of the first marking ruler 1 is placed at the outer canthus of the eye, because the second marking ruler 2 is a soft ruler, the first marking ruler 1 and the second marking ruler 2 are suitable for the side of the face whose surface is not flat, so that the marking head 4 is placed on the line connecting the outer canthus of the eye and the notch between the tragus, and the first marking ruler 1 is provided with a connecting shaft 5 for installing the connecting shaft 5 The mounting groove 6, the driving component 3 includes a connecting shaft 5, and slide grooves 7 are arranged on the inner walls on both sides of the mounting groove 6. The two sides of the connecting shaft 5 are slidably connected in the slide grooves 7 through a plurality of pulleys 8. The top of the connecting shaft 5 extends out of the mounting groove 6 and is connected to the pressing head 9. The bottom of the pressing head 9 is connected to the top of the first marking ruler 1 through a spring 10. The marking head 4 is located in the mounting groove 6 when the spring 10 is reset. The marking head 4 is driven by the driving component 3 to mark the side of the patient's face. When the driving component 3 is used, the pressing head 9 is pressed by the hand, and the pressing head 9 compresses the spring 10 to drive the marking head 4 to move to the side of the patient's face for marking. Finally, the hand is separated from the pressing head 9, and the marking head 4 is driven to move to the mounting groove 6 under the reset action of the spring 10, so that the medical staff can inject medicine to the marked point.

[0018] In this embodiment, a soft cotton pad 11 is provided at the bottom of the first marking ruler 1 and the second marking ruler 2 to increase the comfort when the first marking ruler 1 and the second marking ruler 2 are placed on the patient's face.

[0019] In this embodiment, a connection block 12 is provided on one end of the first marking ruler 1 away from the hinged portion with the second marking ruler 2. The width of the connection block 12 is smaller than that of the first marking ruler 1, so that the connection block 12 can be placed between the tragus.

[0020] In this embodiment, one end of the first marking ruler 1 and the corners of the second marking ruler 2 are rounded to prevent the corners of the first marking ruler 1 and the second marking ruler 2 from causing damage to the patient's face.

[0021] In this embodiment, the installation position of the driving component 3 is one centimeter away from the connecting block 12 to determine the needle insertion point for injection into the upper cavity of the patient's temporomandibular joint.

[0022] In this embodiment, a marking line 13 is provided in the middle of the second marking ruler 2, the connecting block 12 of the first marking ruler 1 is placed between the tragus, and the marking line 13 on the end of the second marking ruler 2 away from the hinged portion with the first marking ruler 1 is placed at the outer canthus of the eye, so that the marking head 4 is placed on the line connecting the outer canthus of the eye and the notch between the tragus.

[0023] Working principle: When using this type of temporomandibular joint superior cavity injection marking ruler, first place the connecting block 12 of the first marking ruler 1 between the tragus, and then place the marking line 13 on one end of the second marking ruler 2 away from the hinged part of the first marking ruler 1 at the outer canthus of the eye. Since the second marking ruler 2 is a soft ruler, the first marking ruler 1 and the second marking ruler 2 are suitable for the side of the face whose surface is not flat, so that the marking head 4 is placed on the line connecting the outer canthus of the eye and the notch between the tragus, and the marking head 4 is driven by the driving component 3 to mark the side of the patient's face, which is more efficient. When the driving component 3 is used, the pressing head 9 is pressed by the hand, and the pressing head 9 compresses the spring 10 to drive the marking head 4 to move to the side of the patient's face for marking. Finally, the hand is separated from the pressing head 9, and the spring 10 is reset to drive the marking head 4 to move to the installation groove 6, so that medical staff can inject drugs at the marked point.
