Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a support frame for a surgical mouth and throat opening device. Background Technology

[0002] During oral and pharyngeal surgeries, mouth openers are needed to open the mouth. These mouth openers require support to ensure they are properly positioned. Currently, there are three main methods of supporting mouth openers in clinical practice: first, the surgical assistant uses their hand for support; second, a rolled-up towel or cloth is used for fixation; and finally, a support frame is used.

[0003] The first method of support requires additional medical staff, who must maintain their posture and occupy space next to the operating table. The second method is prone to being bumped and shifting. The third method uses a triangular support frame with two flat supports on either side, each with several evenly distributed round holes. During support, the round holes on the two supports overlap, and the outer end of the mouth opener rests against the overlapping holes. However, the long arm of the mouth opener has a curved section to prevent slippage. When fixing it to the support, it needs to be raised first, inserted into the two round holes, and then lowered. This raising and lowering prevents the mouth opener from exposing the oral cavity and pharynx in the optimal position, and raising the long arm too high can easily damage the incisors. Therefore, there is an urgent need for a convenient and quick-to-use support frame. Utility Model Content

[0004] To address the inconvenience and slowness of using mouth opener supports in existing technologies, this utility model proposes a surgical mouth and throat mouth opener support frame.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A surgical mouth and throat mouth opening device support frame includes: a T-shaped frame and a slider. The T-shaped frame has screw teeth on its longitudinal axis. The slider includes a sliding frame, an adjusting member, and a U-shaped rod. The sliding frame is slidably disposed on the longitudinal axis. The adjusting member is disposed on the sliding frame and acts on the longitudinal axis to allow the sliding frame to slide or be fixed on the longitudinal axis. The U-shaped rod is fixed on the sliding frame and is used to support the long arm of the mouth opening device.

[0007] Preferably, the sliding frame is configured as a cuboid structure with openings at the front and back, which is simple in structure and facilitates the connection of the adjusting component and the U-shaped rod.

[0008] Preferably, a slot is provided on the lower front side of the sliding frame, and the adjusting component includes an adjusting plate and a spring. One end of the adjusting plate is configured as a hook, which passes through the slot and engages with the threaded teeth of the longitudinal axis, creating a gap between the adjusting plate and the sliding frame. The other end of the adjusting plate is fixed with a spring between it and the sliding frame. The state of the spring causes the hook to engage with the threaded teeth on the longitudinal axis, facilitating the fixing of the slider to the longitudinal axis of the T-shaped frame and enabling one-handed operation.

[0009] Preferably, the sliding frame is provided with a limit ring, and the limit ring and the adjusting member are located on the front and back of the sliding frame, respectively, to facilitate limiting the position of the fingers during use.

[0010] Preferably, the U-shaped rod can be configured as a crossbar and two side bars, with the crossbar fixed to the two side bars and the two side bars fixed to the sliding frame.

[0011] Preferably, the U-shaped rod is located on the front of the sliding frame and above the adjusting member to avoid interference with the adjusting member and the limiting ring.

[0012] Preferably, the sliding frame is provided with a hinge seat, which is located between the spring and the slot. The top end of the hinge seat is a movable end, and an adjustment piece is connected to the top end of the hinge seat to improve the stability of the adjustment component.

[0013] Preferably, the limiting ring includes two rings for placing the index and middle fingers, which facilitates control of the slider's direction and position and allows for one-handed operation.

[0014] The beneficial effects of this utility model are as follows: The surgical mouth and throat mouth opening device support frame of this utility model directly uses the movement of the sliding frame to drive the U-shaped rod, so that the long arm of the mouth opening device is positioned in the required fixed position with the help of the U-shaped rod. This avoids the positional difference caused by lifting and lowering the long arm of the mouth opening device when fixing it. Moreover, in clinical use, doctors can operate it with one hand, and one doctor can open and fix the mouth opening device at the same time. The fixation is simplified and convenient, improving the efficiency and convenience of use. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: As Figures 1 to 4 The surgical mouth and throat mouth opening device support frame shown includes: a T-shaped frame 1 and a slider 2. The T-shaped frame 1 has screw teeth on its longitudinal axis 11. The slider 2 includes a sliding frame 21, an adjusting member 22, and a U-shaped rod 23. The sliding frame 21 is slidably mounted on the longitudinal axis 11. The adjusting member 22 is located on the front of the sliding frame 21 and acts on the longitudinal axis 11, so that the sliding frame 21 can slide freely or be fixed freely on the longitudinal axis 11. The U-shaped rod 23 is fixed on the sliding frame and is used to support the long arm of the mouth opening device. Two limiting rings 24 are provided on the back of the sliding frame. The position of the U-shaped rod 23 changes as the sliding frame slides on the longitudinal axis.

[0024] The U-shaped bar is used to fix the long arm of the mouth opener in a suitable position. The long arm of the mouth opener is located on the U-shaped bar. The U-shaped bar and the long arm of the mouth opener move together actively to the position where the long arm of the mouth opener needs to be fixed, or the U-shaped bar moves to the position where the long arm of the mouth opener needs to be fixed. This avoids positional differences caused by lifting and lowering the long arm of the mouth opener during fixing. Direct fixing improves both efficiency and convenience of use. The size of the T-frame and slider can be set according to different age groups of patients.

[0025] like Figure 3As shown, the sliding frame 21 is a cuboid structure with openings at the front and back. It has a simple structure and slides on the longitudinal axis of the T-shaped frame. The sliding frame 21 has a slot 25 on the lower front side for the adjusting plate to act on the screw teeth on the longitudinal axis, so that the slider is fixed on the longitudinal axis of the T-shaped frame.

[0026] like Figure 4 As shown, the adjusting component 22 includes an adjusting plate 3, a spring 4, and a hinge seat 5. One end of the adjusting plate 3 is configured as a hook 6, which passes through the slot 25 and engages with the threaded teeth of the longitudinal shaft 11, creating a gap between the adjusting plate 3 and the sliding frame 21. The other end of the adjusting plate 3 is fixed between the adjusting plate 3 and the sliding frame 21, and the state of the spring 4 causes the hook 6 to engage with the threaded teeth on the longitudinal shaft. The hinge seat 5 is fixed on the sliding frame 21 located between the spring and the slot. The top end of the hinge seat 5 is a movable end, and the top end of the hinge seat 5 is connected to the adjusting plate 3.

[0027] The adjusting component can also be configured with other existing structures, but the adjusting component structure of this application is simple and convenient to use, can be operated with one hand, and is even more convenient to use when combined with the T-shaped frame. The hinged seat design improves the stability of the connection between the adjusting plate's hook and the longitudinal axis of the T-shaped frame, and extends the service life of the adjusting plate.

[0028] The U-shaped rod 23 can be configured as a crossbar and two side bars, with the crossbar fixed to the two side bars and the two side bars fixed to the sliding frame. The U-shaped rod 23 is located on the front of the sliding frame and above the adjusting component.

[0029] This utility model relates to a surgical mouth and throat mouth opening device support frame. During surgery, after successfully placing the mouth opening device in the mouth, the surgeon holds the long arm of the mouth opening device with their left hand to maintain the required height, and holds the support frame with their right hand. Two fingers are positioned within the two limiting rings to adjust the direction and position of the support frame. The thumb presses down on one end of the fixing spring of the adjusting plate, compressing the spring and disengaging the hook from the screw teeth. The sliding frame slides up and down along the longitudinal axis. The U-shaped rod on the sliding frame is aligned with the end of the long arm of the mouth opening device. After finding a suitable height, the thumb is released to fix the position of the U-shaped rod, directly locking the long arm of the mouth opening device onto the U-shaped rod. At this point, the entire support frame remains stationary, and the mouth opening device is quickly and easily fixed in the appropriate position.

[0030] This utility model relates to a surgical mouth and throat mouth opening device support frame. During surgery, after successfully placing the mouth opening device in the mouth, the surgeon holds the long arm of the mouth opening device with their left hand and adjusts the direction and position of the support frame with their right hand. The support frame is placed on one side of the long arm of the mouth opening device, and then the long arm of the mouth opening device is secured to the U-shaped rod. The slider is operated as described above, allowing the slider to slide along the longitudinal axis, actively moving the long arm of the mouth opening device and the U-shaped rod to the height required to keep the mouth opening open. If the mouth opening position is not suitable, the direction and position of the support frame can be finely adjusted until the mouth opening position is appropriate. Finally, the slider is locked, which also locks the U-shaped rod, achieving rapid fixation of the mouth opening device.

[0031] The surgical mouth and throat opening device support frame of this utility model can be used in various ways. In practice, users can choose to use it themselves. They can also adjust the direction and position of the support frame and the height and direction of the long arm of the mouth opening device at the same time, thereby adjusting the opening position of the mouth opening device. There are many ways to use it.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
