Description

Technical Field

[0001] This utility model relates to the field of surgical instrument technology, specifically a T-shaped forceps suitable for maxillofacial surgery. Background Technology

[0002] T-forceps are specialized instruments used in oral and maxillofacial surgery to open and keep the patient's mouth open. Their name comes from their structural shape. They usually consist of two sets of staggered or symmetrical forceps, which can effectively assist doctors in performing intraoral operations.

[0003] Existing T-shaped forceps typically have thinner handles. Although they have transverse grooves for anti-slip, the small contact area between the handle and the patient's mouth makes it easy for the handle to slide and shift when twisted open. This hinders stable contact between the handle and the patient's jaw, thus affecting the opening effect of the forceps. Furthermore, during the tightening process, the gap between the handle and the retaining bar is small, and the surfaces of the handle and retaining bar are flush. When the user grips the retaining bar and twists the screw to tighten the handle, fingers can easily get caught in the gap, posing a risk of injury. Utility Model Content

[0004] The purpose of this invention is to provide a T-shaped forceps suitable for maxillofacial surgery to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a T-shaped forceps suitable for maxillofacial surgery, comprising a fixing plate, a torsion plate on the back of the fixing plate, a screw fixedly connected to the front of the torsion plate, thickening blocks on both the top and bottom surfaces of the fixing plate, a frosted groove at the top of the thickening blocks, a first movable forceps bar and a second movable forceps bar respectively on both sides of the front of the fixing plate, a first biting bar at the end of the first movable forceps bar, a second biting bar at the end of the second movable forceps bar, a biting groove on one side wall of both the first and second biting bars, and a notch at the top of the biting groove.

[0006] Preferably, a screw hole is provided in the center of the front side of the fixing plate, and the screw is connected to the fixing plate through the screw hole via a movable thread.

[0007] Preferably, both ends of the fixing plate are rotatably connected to rotating rods, and the head ends of the first movable clamp rod and the second movable clamp rod are respectively fixedly connected to the middle of the two rotating rods. The first movable clamp rod and the second movable clamp rod are rotatably connected to the fixing plate through the rotating rods.

[0008] Preferably, a silicone strip is embedded in the inner wall of the bite groove.

[0009] Preferably, a washer is provided at the end of the screw away from the torsion plate, and the washer is slidably connected to the first movable clamp rod and the second movable clamp rod through the screw.

[0010] Preferably, a limiting cylinder is provided in the middle of the back of the fixing plate, and the screw is threadedly connected to the limiting cylinder.

[0011] Preferably, the torsion plate is rotatably connected to the fixed plate via a screw.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This T-shaped forceps is applicable to maxillofacial surgery. With its first bite bar, second bite bar, bite groove, and notch, when the end of the T-shaped forceps is inserted into the patient's maxillofacial oral cavity at the lip, the patient's upper teeth can bite the first bite bar through the bite groove, and the lower teeth can bite the second bite bar through the bite groove. This increases the contact area between the end of the forceps and the patient's maxillofacial region, improves the stability of the forceps when opening the patient's oral cavity, and thus enhances the opening effect of the T-shaped forceps.

[0014] 2. This T-shaped forceps is suitable for maxillofacial surgery. With the addition of thickened blocks and abrasive grooves, when the user's hand is squeezing the fixing bar of the T-shaped forceps to twist the screw, the fingers can be placed on the abrasive grooves for restraint. This not only increases the friction coefficient between the user's hand and the T-shaped forceps, making it easier to twist the screw, but also elevates the user's fingers, preventing them from getting caught in the gap between the fixing bar and the forceps bar, thereby reducing the risk of the user being pinched by the forceps bar.

[0023] like Figures 1 to 4As shown, this embodiment is applicable to T-shaped forceps for maxillofacial surgery, including a fixing plate 5. The function of the fixing plate 5 is to limit the screw 2 and the two forceps bars, so that when the screw 2 is turned, it can push the forceps bars symmetrically arranged on both sides of the fixing plate 5, thereby opening the first movable forceps bar 7 and the second movable forceps bar 8. A torsion plate 1 is provided on the back of the fixing plate 5. The function of the torsion plate 1 is to facilitate the torsion of the screw 2 so that the screw 2 can rotate in the screw hole 16. The screw 2 is fixedly connected to the front of the torsion plate 1. After the screw 2 is torsioned, the end of the screw 2 will protrude from the screw hole 16 on the front of the fixing plate 5, thereby... To enable the pushing of the first movable clamp 7 and the second movable clamp 8, the top and bottom surfaces of the fixed plate 5 are both equipped with thickening blocks 4. The thickening blocks 4 and the fixed plate 5 are integrally structured, which can offset the planes where the movable clamps and the fixed plate 5 are located, raising the plane where the user's fingers are located, thereby reducing the probability of the user's fingers getting stuck in the gap between the movable clamps and the fixed plate 5. The top of the thickening block 4 has a frosted groove 3, and the surface of the frosted groove 3 is sprayed with frosted particles, which can increase the friction coefficient between the fingers and the thickening block 4, thus making it easier for the user to grip the fixed plate 5 with the thickening block 4. The front side of the fixed plate 5 is provided with a first movable clamp 7 and a second movable clamp 8 on both sides. The first movable clamp 7 and the second movable clamp 8 are symmetrically arranged on both sides of the fixed plate 5 and can be pushed by the screw 2. The end of the first movable clamp 7 is provided with a first bite bar 10, and the end of the second movable clamp 8 is provided with a second bite bar 12. The first bite bar 10 and the second bite bar 12 are designed with an "arc" shape, which can fit the labial and dental arc surface of the patient's jaw, thereby facilitating the patient's biting on the first bite bar 10 and the second bite bar 12. The first bite bar 10 and the second bite bar 12 are integrated with the movable clamps. To improve the stability of the first bite bar 10 and the second bite bar 12, a bite groove 9 is provided on one side wall of both the first bite bar 10 and the second bite bar 12. The function of the bite groove 9 is to facilitate the patient to bite the end of the movable forceps bar with their teeth, thereby expanding the contact surface between the T-shaped forceps and the patient's jaw surface, which helps to improve the stability of the T-shaped forceps. A notch 15 is provided at the top of the bite groove 9. Since the length of the first bite bar 10 and the second bite bar 12 does not completely cover the teeth of the patient's jaw surface, the function of the notch 15 is to allow the bite bar to better fit the patient's teeth, thereby facilitating the patient to bite the bite bar.

[0024] Specifically, a screw hole 16 is provided in the middle of the front side of the fixing plate 5. The screw 2 is connected to the fixing plate 5 through the screw hole 16 via a movable thread. The function of the screw hole 16 is to allow the end of the screw 2 to pass through the front side of the fixing plate 5, thereby enabling the screw 2 to push the movable clamp rod.

[0025] Furthermore, both ends of the fixing plate 5 are rotatably connected to rotating rods 6. The head ends of the first movable clamp rod 7 and the second movable clamp rod 8 are respectively fixedly connected to the middle of the two rotating rods 6. The first movable clamp rod 7 and the second movable clamp rod 8 are rotatably connected to the fixing plate 5 through the rotating rods 6, so that the first movable clamp rod 7 and the second movable clamp rod 8 can rotate outwards simultaneously along both ends of the fixing plate 5, thereby opening the two movable clamp rods and opening the patient's maxillofacial oral cavity with the movable clamp rods.

[0026] Furthermore, a silicone strip 11 is embedded in the inner wall of the bite groove 9. The silicone strip 11 is made of medical-grade silicone and its function is to facilitate the patient's teeth to bite the bite strip tightly, thereby enhancing the fit and stability of the bite strip with the patient's jaw and face, and further improving the stability of the T-shaped forceps in the patient's jaw and face oral cavity.

[0027] Furthermore, a washer 14 is provided at the end of the screw 2 away from the torsion plate 1. The washer 14 is slidably connected to the first movable clamp rod 7 and the second movable clamp rod 8 through the screw 2. The function of the washer 14 is to avoid direct contact between the screw 2 and the movable clamp rod, thereby reducing the wear between the screw 2 and the movable clamp rod.

[0028] Furthermore, a limiting sleeve 13 is provided in the middle of the back of the fixing plate 5. The screw 2 is connected to the limiting sleeve 13 by a movable thread. The function of the limiting sleeve 13 is to limit the torsion plate 1 and prevent the torsion plate 1 from being stuck in the fixing plate 5 by the screw 2, thereby facilitating the subsequent torsion of the torsion plate 1.

[0029] Furthermore, the twist plate 1 is rotatably connected to the fixing plate 5 via the screw 2. The surface of the twist plate 1 is concave inward, making it easy for the user to fit it tightly, thus facilitating the user to twist the twist plate 1.

[0030] The method of use in this embodiment is as follows: When using this T-shaped forceps applicable to maxillofacial surgery, the user can first clamp it tightly onto the thickened block 4 of the fixing plate 5 through the abrasive groove 3, and then twist the torsion plate 1, causing the torsion plate 1 to drive the screw 2 to rotate. At this time, the washer 14 at the end of the screw 2 will move towards the contact point of the first movable forceps 7 and the second movable forceps 8. Then continue to twist the torsion plate 1, causing the screw 2 to spread the first movable forceps 7 and the second movable forceps 8 apart. When the first movable forceps 7 and the second movable forceps 8 drive the first bite bar 10 and the second bite bar... After the first biting bar 10 and the second biting bar 12 are opened to a suitable angle, they can be placed into the patient's oral cavity, so that the patient's upper and lower teeth can bite into the occlusal grooves 9 of the first biting bar 10 and the second biting bar 12 respectively. Then, the torsion plate 1 can be turned to drive the screw 2 to continue to open the first movable clamp 7 and the second movable clamp 8 until the patient's oral cavity is opened to a suitable angle by the first biting bar 10 and the second biting bar 12. Then, the torsion plate 1 is stopped, and the T-shaped forceps are stably held in the patient's oral cavity.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
