Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical instruments, and more particularly to a double-jointed tongue retractor for oral surgery. Background Art
[0002] Oral surgery, also known as oral and maxillofacial surgery, is an important branch of stomatology. It focuses on the treatment of oral and maxillofacial diseases and functional restoration through surgical means, covering diseases of the teeth, alveolar bone, jaw, temporomandibular joint, salivary glands, and facial soft tissues. Its treatment areas can be divided into: (1) Alveolar surgery: such as complex tooth extraction (impacted wisdom teeth, impacted teeth), alveolar bone repair, etc. (2) Maxillofacial diseases: including cysts (such as jaw cysts), tumors (such as tongue cancer, gum cancer), infections (maxillofacial space infections), etc. (3) Trauma and deformity repair: such as jaw fracture reduction, cleft lip and palate repair, orthognathic surgery (correction of jaw developmental deformities). (4) Functional surgery: treatment of temporomandibular joint disorders, dental implant surgery, salivary gland diseases (such as parotid tumor resection).
[0003] During oral surgery, a long period of time is required to assist the operation with the help of a tongue retractor and an opener. The tongue retractor currently used has a very simple structure and needs to be held by the surgeon. Moreover, the simultaneous use of the opener and the tongue retractor requires multiple people to operate, and takes up more space, which affects the operation of the operation. Furthermore, the opening degree of the existing opener depends entirely on the surgeon's experience, and it is impossible to achieve rapid positioning while meeting precise fine-tuning. In addition, the patient's mouth maintains a certain opening angle for a long time, especially for patients with poor bite, the oral muscles are prone to stiffness, resulting in the patient's inability to cooperate.
[0004] Therefore, the present invention proposes a double-jointed tongue retractor for oral surgery. Summary of the Invention

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:
[0029] Example
[0030] like Figures 1 to 6 As shown, the double-jointed tongue retractor 4 for oral surgery includes a first joint clamp assembly and a cross-arranged second joint clamp assembly. The first joint clamp assembly includes a first joint clamp A1 and a first joint clamp B2. The middle part of the first joint clamp A1 is rotatably connected to the middle part of the first joint clamp B2 through a rotating shaft. One end of the first joint pliers assembly is hinged to a first connecting rod through a pin, and the other end is provided with a positioning assembly. The free end of the first connecting rod is connected to a connecting rod for damping rotation. The connecting rod is hinged to the second joint pliers assembly through a pin. The free end of the second joint pliers assembly is provided with a mouth opener 3. A fixed frame 24 is fixedly connected between the two connecting rods by a spring. A slider 25 extending toward the first joint pliers A1 to the outside of the fixed frame 24 is slidably clamped in the fixed frame 24. A first screw 26 passing through the slider 25 is rotatably clamped in the fixed frame 24. The first screw 26 located outside the fixed frame 24 is fixed with a second knob. The side of the slider 25 located outside the fixed frame 24 is rotatably clamped with a first knob 31. The first knob 31 is threadedly connected to the second screw 27 passing through the fixed frame 24. One end of the second screw 27 is detachably connected to a tongue hook 4, and the other end is provided with a limit block.
[0031] The second articulated pliers assembly includes a second connecting rod A16, a second connecting rod B17, a second articulated pliers A18 and a second articulated pliers B19. The second articulated pliers A18 and the second articulated pliers B19 are cross-hinged. The middle and end parts of the second connecting rod A16 are respectively hinged to the end part of the second articulated pliers B19 and the middle part of the second articulated pliers A18. The middle and end parts of the second connecting rod B17 are respectively hinged to the end part of the second articulated pliers A18 and the middle part of the second articulated pliers B19. The ends of the second connecting rod A16 and the second connecting rod B17 are respectively connected to the second articulated pliers A18 and the second articulated pliers B19 through tension springs.
[0032] The mouth opener 3 includes two symmetrically arranged support blocks 20, fixedly connected to the ends of the second connecting rod A16 and the second connecting rod B17, respectively. The opposing sides of the two support blocks 20 are inclined and equipped with a plurality of stop bars 21. The opposing sides of the two support blocks 20 are flat or concave, also equipped with a plurality of stop bars 21. The ends of the support blocks 20 are detachably connected to curved mounting plates 22. Two curved support plates 23 are symmetrically arranged, and the curved support plates 23 are spring-loaded into the grooves of the curved mounting plates 22.
[0033] The positioning assembly includes a fixing ring 5 and a limiting ring 6 which are respectively rotatably clamped on the sides of the first joint pliers A1 and the first joint pliers B2. The limiting ring 6 is threadedly connected to a sleeve 12, and retaining rings are provided at both ends of the sleeve 12. A positioning rod 7 extending into the sleeve 12 is rotatably clamped in the fixing ring 5. The outer surface of the positioning rod 7 is provided with a ridge 13 extending into the sleeve 12 along its length. The outer periphery of the positioning rod 7 is symmetrically provided with a number of linearly distributed grooves, and a limiting rod 8 is provided in the groove. The limiting rod 8 is slidably clamped with a hollow rod, and a positioning ball 9 is provided at one end of the hollow rod away from the limiting rod 8. The positioning ball 9 is fixedly connected to the groove by a spring sleeved on the limiting rod 8. A positioning groove 11 adapted to the positioning ball 9 is provided in the sleeve 12. A tensioning screw 14 is threadedly clamped on the top of the positioning rod 7, and retaining rings are provided at both ends of the tensioning thread. The positioning ball 9 is provided with a pull rope 15 which passes through a through hole of the positioning rod 7 and is fixedly connected to the bottom of the tensioning screw 14.
[0034] The side of the first joint pliers assembly is detachably connected to a fixing assembly, which includes a support rod 28 detachably connected to the first joint pliers A1 or the first joint pliers B. A U-shaped block 29 is provided at the bottom of the support rod 28, and a fastening screw 30 is threadedly connected to one side of the U-shaped block 29.
[0035] It should be noted here that the front and back sides of the tongue retractor 4 can be detachably connected to the second screw 27, and the support rod 28 can be detachably connected to the first joint clamp A1 or the first joint clamp B, so that it is suitable for both right-handed surgeons and left-handed patients.
[0036] Here’s how it works:
[0037] In the natural state, the two support blocks 20 are close to each other, and the distance between the first joint clamp A1 and the first joint clamp B2 is far away from each other; and the lower surface of the retaining ring at the top of the tensioning screw 14 is against the positioning rod 7, and the positioning ball 9 is completely located in the positioning groove 11.
[0038] When in use, the support block 20 and the second joint pliers are placed on the same water surface, the tensioning screw 14 is rotated to move the tensioning screw 14 upward, and the positioning ball 9 can be moved toward the positioning rod 7 by the pull rope 15 until the upper surface of the retaining ring at the bottom of the tensioning screw 14 abuts against the positioning rod 7. At this time, although the positioning ball 9 is still partially in the positioning groove 11, it is only necessary to apply force to bring the first joint pliers A1 and the first joint pliers B2 closer to each other to easily free the positioning ball 9 from the restriction of the positioning groove 11. The first joint pliers A1 and the first joint pliers B2 approaching each other can drive the two support blocks 20 away from each other until the distance between the two support blocks 20 reaches the desired distance, and the positioning ball 9 is stuck in the positioning groove 11 under the restoring force of the compression spring; then the tensioning screw 14 is rotated to move the tensioning screw 14 downward until the lower surface of the retaining ring at the top of the tensioning screw 14 abuts against the positioning rod 7. At this time, the positioning ball 9 can be stably and firmly limited, thereby achieving the purpose of rapid positioning.
[0039] By rotating the sleeve 12 simultaneously, the distance between the two support blocks 20 can be fine-tuned within the limits of the ridges 13, meeting the need for precise fine-tuning. The first jointed forceps assembly is then rotated to form an angle with the second jointed forceps assembly. The first jointed forceps B2 can then be fixed to the operating chair or bed using the fixing assembly, which not only expands the surgeon's field of view but also reduces the surgeon's fatigue from holding the tongue depressor for extended periods of time.
[0040] The position of the tongue hook 4 can be adjusted in two dimensions through the first screw 26 and the second screw 27. Since the tongue hook 4 and the second screw 27 are detachably connected, the tongue hook 4 can be replaced according to different needs. In addition, a connecting component composed of two connecting plates with one end hinged to each other can be provided between the second screw 27 and the tongue hook to adjust the angle of the tongue hook 4.
[0041] In addition, stop strips 21 are provided on the opposite surfaces of the two support blocks 20, which can be used not only as a mouth opener 3, but also as a tool for tooth extraction or other purposes. Moreover, the detachably connected arc-shaped mounting plate 22 and arc-shaped support plate 23 of the support block 20 can keep the patient's mouth open for a long time, provide a certain amount of space for movement, and relieve the patient's oral muscle stiffness.
[0042] The above is only an embodiment of the present invention, and the common knowledge such as the specific technical solutions and / or characteristics in the solution are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the description can be used to interpret the content of the claims.
