Abstract
Description
Technical Field
[0001] This utility model relates to the field of lingual retractor technology, specifically a lingual retractor for oral and maxillofacial surgery. Background Technology
[0002] The lingual retractor in oral and maxillofacial surgery is an important medical instrument in this field. It typically consists of a handle and a retractor head, which is usually curved, tough, and smooth. It plays a crucial role in oral and maxillofacial surgical procedures. For example, during jaw-related surgeries and the removal of intraoral tumors, the surgeon can hold the handle and place the retractor head in a suitable position on the lingual side to retract the tongue, fully exposing the surgical field and facilitating precise manipulation while avoiding tongue interference. Its proper use helps improve surgical efficiency and quality, ensuring the smooth progress of surgery, making it a valuable tool for oral and maxillofacial surgeons.
[0003] Existing lingual retractors require a high level of hand strength to hold during prolonged surgeries, which can easily lead to hand fatigue for surgeons. This may affect the stability of the retractor and make it difficult to maintain a good surgical field of vision. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lingual retractor for oral and maxillofacial surgery, comprising a hook body, wherein a pulling mechanism is installed in the middle of the hook body;
[0006] The hook body includes an extension piece, and an upper clamping piece and a lower clamping piece are fixedly connected to the left side and bottom of the extension piece, respectively. A through hole is provided between the upper clamping piece, the lower clamping piece and the extension piece.
[0007] Preferably, the upper clamping piece, the lower clamping piece, and the extension piece are integrally formed, and the upper clamping piece and the lower clamping piece are bent close to each other.
[0008] Preferably, the pulling mechanism includes a limiting seat, a sliding block is slidably connected inside the limiting seat, a pull rod is slidably connected to the left side of the limiting seat, a movable plate is rotatably connected to the left end of the pull rod, movable rods are hinged to the top and bottom of the movable plate, and a hinge block is hinged to the end of the movable rod away from the movable plate.

[0013] Compared with the prior art, this utility model provides a lingual retractor for oral and maxillofacial surgery, which has the following beneficial effects:
[0014] 1. This oral and maxillofacial surgical tongue retractor, through the hook body, allows for easy pulling and retraction of the tongue by squeezing the extension piece and using the elastic clamping force of the upper and lower clips, thereby reducing hand fatigue.
[0015] 2. This oral and maxillofacial surgical lingual retractor, through its designed pulling mechanism, allows the upper and lower clips to be used for clamping when necessary. The retractor slides within the groove via a recessed block, which in turn drives the pull rod to pull the movable plate. With the assistance of the movable rod, the upper and lower clips move closer together, effectively clamping the tongue and reducing hand fatigue. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0024] This utility model provides the following technical solution:
[0025] Example 1
[0026] Please see Figure 1-4 A lingual retractor for oral and maxillofacial surgery includes a hook body 1, with a pulling mechanism 2 installed in the middle of the hook body 1;
[0027] The hook body 1 includes an extension piece 13. An upper clamping piece 11 and a lower clamping piece 12 are fixedly connected to the left side and bottom of the extension piece 13, respectively. A through hole 14 is provided between the upper clamping piece 11, the lower clamping piece 12 and the extension piece 13.
[0028] With the hook 1 in place, when in use, the extension piece 13 is pinched by hand, and the elastic clamping force of the upper clamp piece 11 and the lower clamp piece 12 makes it easy to pull the tongue away, while reducing hand fatigue.
[0029] The upper clamping piece 11, the lower clamping piece 12, and the extension piece 13 are integrally formed, with the upper clamping piece 11 and the lower clamping piece 12 bending close to each other.
[0030] Example 2
[0031] Please see Figure 1-4 Furthermore, based on Embodiment 1, the pulling mechanism 2 further includes a limiting seat 21, a sliding block 291 slidably connected inside the limiting seat 21, a pull rod 29 slidably connected to the left side of the limiting seat 21, a movable plate 24 rotatably connected to the left end of the pull rod 29, a movable rod 27 hinged to the top and bottom of the movable plate 24, and a hinge block 25 hinged to the end of the movable rod 27 away from the movable plate 24.
[0032] With the pull mechanism 2 in place, when the upper clamping plate 11 and the lower clamping plate 12 need to be clamped, the groove block 292 can slide in the slide groove 23, thereby driving the pull rod 29 to drive the movable plate 24 to pull. At this time, with the help of the movable rod 27, the upper clamping plate 11 and the lower clamping plate 12 can be brought closer to each other, thus clamping the tongue, reducing the grip of the hand, and further reducing hand fatigue.
[0033] A groove block 292 is fixedly connected to the top center of the sliding block 291, and a groove 23 is opened at the bottom of the limiting seat 21 corresponding to the groove block 292. The groove block 292 is slidably connected in the groove 23.
[0034] A limit hole 22 is provided on the left side of the limit seat 21, and a pull rod 29 is slidably connected to the limit seat 21 through the limit hole 22.
[0035] The left end of the pull rod 29 extends through the through hole 14 to the space between the upper clamping plate 11 and the lower clamping plate 12. The inner sides of the upper clamping plate 11 and the lower clamping plate 12 are fixedly connected to the outer side of the hinge block 25. The hinge block 25 is fixedly connected to the middle of the hinge rod 26. The hinge block 25 is hinged to the hinge rod 26 through the hinge rod 26.
[0036] The movable plate 24 has a pull hole 28 in the middle, and the pull rod 29 is rotatably connected in the pull hole 28. The pull rod 29 is fixedly connected to the first limiting piece 293 on the left side of the movable plate 24, and the pull rod 29 is fixedly connected to the second limiting piece 294 on the right side of the movable plate 24.
[0037] In actual operation, when this device is used, the extension piece 13 is pinched by hand. Through the elastic clamping force of the upper clamp piece 11 and the lower clamp piece 12, the tongue can be easily pulled and avoided, while reducing hand fatigue.
[0038] When the upper clamping plate 11 and the lower clamping plate 12 need to be clamped, the groove block 292 can slide in the slide groove 23, thereby driving the pull rod 29 to drive the movable plate 24 to pull. At this time, with the help of the movable rod 27, the upper clamping plate 11 and the lower clamping plate 12 can be brought closer to each other, thereby clamping the tongue, reducing the grip of the hand, and further reducing hand fatigue.
[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
