Description

Technical Field

[0001] The utility model relates to the technical field of oral surgery tables, in particular to an oral surgery table for rats and mice which can adjust three-dimensional directions. Background Art

[0002] Performing surgery in the oral cavity of mice and rats and establishing various types of oral disease models are important means of basic research in oral medicine. During the operation, it is the key to the success of the operation to quickly and stably fix the head of the mouse and rat and accurately and comprehensively expose the operation area in the oral cavity. Due to the small structure of the oral cavity of mice and rats, the surgical field of view is limited, and the operating space is small, the operation is time-consuming and laborious.

[0003] In the prior art, Chinese patent CN219354260U discloses a mouse oral experimental fixing device, including a surgical board, a support table, and an elastic rubber band, a detachable baffle, and the elastic rubber band is respectively wrapped around the maxillary teeth and the mandibular teeth, so as to open the mouse's mouth, and the detachable baffle blocks the movement of the mouse's head. One end of the elastic rubber band of the patent is sleeved on the mouse's mandibular teeth, and the other end is fixed on a fixed column in the direction of the mouse's tail. The magnitude of the elastic rubber band tension can be roughly adjusted by different slots on the fixed column. Since different surgical methods require different opening directions and degrees of large / small mice, the patent cannot adjust the direction and magnitude of the tension at the same time. The detachable baffle in the patent can prevent the mouse's head from moving to a certain extent, but if a large force is applied to the mouse's unilateral teeth (such as tooth extraction surgery, thread embedding surgery, etc.), the mouse's head will still produce a large rotation, resulting in unclear surgical field or dislocation of the elastic rubber band, and ultimately causing the operation to be interrupted.

[0004] Chinese patent CN212996873U discloses a fixation device for oral surgery on mice, including an operating table and a fixed cabin. The operating table is provided with bearings inside, and a movable plate is connected to adjust the angle of the head. This patent can only adjust the angle of the mouse's head within a small angle, and cannot adjust the direction and degree of the mouse's mouth opening, and there is still a problem of unclear vision. At the same time, the movable plate is separated from the elastic rubber band that opens the mouse's mouth, resulting in a change in the mouse's opening degree while adjusting the mouse's angle, and may cause the elastic rubber band to loosen, affecting the operation.

[0005] The height of the operating table is closely related to the efficiency of the operation and the comfort of the operator. The appropriate height of the operating table can ensure that the operator has a clear field of vision, smooth and comfortable operation with both hands. Different operators need different operating table heights due to different sitting heights, so that the field of vision is parallel to the surgical area, thereby ensuring the accuracy of the operation. At present, most of the disclosed oral surgery devices are fixed flat-panel structures, and the height and inclination of the operating table cannot be adjusted. The field of vision during surgery is poor. In order to obtain a good field of vision, the operator needs to bend down for a long time to operate, which can easily cause fatigue. In addition, when performing surgery on mice that requires high force, it is impossible to prevent the mouse's head from moving significantly. Utility Model Content

[0025] (5) Compared with previous operating tables, the present invention eliminates the need for fixing devices for the limbs of mice / rat, because experiments have shown that elastic rubber bands and stable lateral fixation of the upper and lower jaws of mice / rat are sufficient to ensure the stability of the oral position during surgery. No other additional fixing devices are required except for the mouse tail fixing clamp, thus saving time for pre-operative preparation. BRIEF DESCRIPTION OF THE DRAWINGS

Multiple grooves are arranged at equal intervals. In the utility model, the material of the plastic movable plate is PVC.

[0034] A third handle screw 4 is provided on both sides of the second plastic movable plate 16, and the third handle screw 4 is connected to an electric lifting rod 5. The electric lifting rod 5 is connected to a driving motor 6, and the driving motor 6 is connected to a wired remote controller 7. A magnifying glass 10 and an LED searchlight 11 are provided on one side of the second plastic movable plate 16, and the LED searchlight 11 is connected to a plug 14.

[0035] The first handle screw 2 includes a screw rod and a handle. Mounting plates are provided on both sides of the mandibular elastic rubber band fixing rod 1. Mounting holes are provided on the mounting plates. The mandibular elastic rubber band fixing rod 1 and the screw rod are fixedly connected. The screw rod passes through the mounting hole of the mounting plate. The handle is provided on one side of the screw rod.

[0036] One end of the fixed baffle 19 is connected to one end of the spring sheet clamp 20, and the other end of the spring sheet clamp 20 is connected to the wire tail handle 21. The fixed baffle 19 is a curved plate.

[0037] The damping shaft 17 is rotationally connected to the first plastic movable plate 3 , and the damping shaft 17 is rotationally connected to the third plastic movable plate 15 .

[0038] In the utility model, the mandibular elastic rubber band fixing rod 1 has 5 grooves for the elastic rubber band to be inserted into to provide different pulling forces. The angle of the fixing rod can be adjusted by the first handle screw 2, so as to achieve synchronous adjustment of the elastic rubber band pulling force and pulling direction.

[0039] The mandibular elastic rubber band fixing rod 1 is fixedly connected to the screw rod. However, the screw rod is not fixedly connected to the two mounting holes and can rotate. After rotating to a suitable angle, the angle is fixed by tightening the handle of the first handle screw. The first plastic movable plate 3, the second plastic movable plate 16 and the third plastic movable plate 15 serve as the table top of the operating table, and the first plastic movable plate 3 and the third plastic movable plate 15 can rotate through the damping shaft 17.

[0040] The electric lifting rod 5 is arranged on both sides of the second plastic movable plate 16 to control the height of the table.

The third handle screw 4 is connected to the second plastic movable plate 16, and the angle between the operating table and the ground can be manually adjusted to obtain the required surgical field of view. The driving motor 6 drives the lifting and lowering of the lifting rod 5, which is controlled by the wired remote control 7.

[0041] The rat tail fixing clip 8 provided in the utility model can clamp the rat tail to prevent the rat from slipping during the height and angle adjustment of the table, and facilitate the fixing of the upper and lower jaw elastic rubber bands. The rat tail fixing clip 8 can slide in the first long strip hollow groove 9 to adapt to the length and body shape of different rats.

[0042] The working principle of the mouse head fixing clamp 12 is as follows: the operator presses the wire tail handle 21 to loosen the fixing clamp, and uses the spring sheet clamp body 20 to clamp the base of the mouse / rat's ear to prevent the mouse / rat's head from axially rotating during surgery. At the same time, the fixed baffle 19 connected to the spring sheet clamp body 20 presses against the mouse / rat's head to prevent lateral movement. A second long strip hollow groove 23 and a second handle screw 22 are provided below the spring sheet clamp body 20 to adapt to the head widths of different mice / rat's. When the position of the spring sheet clamp body 20 and the fixed baffle 19 needs to be moved, the second handle screw 22 is first unlocked, the spring sheet clamp body 20 and the fixed baffle 19 move along the second long strip hollow groove 23, and then the second handle screw 22 is locked to adapt to the head widths of different mice / rat's.

[0043] The magnifying glass 10 and the LED searchlight 11 are combined into one body, connected to the power supply by the LED searchlight power cord and the plug 14, and can be moved and adjusted in any direction through the metal hose, so as to magnify the minute structures of the oral cavity and provide sufficient lighting, so that the operator can obtain a good surgical field of view, and at the same time prevent the operator from lowering his head too much to see the structures in the oral cavity clearly, thereby effectively protecting the health of the operator's cervical spine.

[0044] The elastic rubber bands 18 inserted into the mandibular elastic rubber band fixing rod 1 and the maxillary elastic rubber band fixing rod 13 pull the mandibular teeth and maxillary teeth of rats / mice.

[0045] The advantages of the utility model are:

[0046] (1) Adjustable in three dimensions: Compared with similar operating tables, the height can be adjusted to match the surgeon's line of sight. The surgeon does not need to bend down or look closer to obtain a better surgical field of view, which is less tiring. The front and back inclination and left and right inclination of the operating table can be adjusted, and the direction of the surgical field of view can be flexibly adjusted according to different surgical methods.

[0047] (2) A new head fixation method improves the stability of the heads of mice and rats during surgery: Compared with similar operating tables, the new head fixation clamp can be used to stabilize the heads of mice and rats more quickly, especially during more intense surgeries, so that the heads of mice and rats are not easily rotated, thereby greatly improving the efficiency of the surgery.

[0048] (3) Clear observation of tiny oral structures: A magnifying glass and searchlight fixed to the operating table are added. The two are combined into one and can be moved and adjusted in any direction through a metal hose to magnify the tiny structures of the oral cavity and provide sufficient lighting, so that the operator can obtain a good surgical field of view. At the same time, it prevents the operator from lowering his head too much to see the oral structures of mice / rat clearly, effectively protecting the health of the operator's cervical spine.

[0049] (4) The mouth opening of rats and mice can be freely adjusted: the direction and tension of the elastic rubber band can be changed by adjusting the angle of the long rod, so as to change the mouth opening of rats and mice, thereby obtaining different surgical fields of view. The mouth opening can also be tilted to the left or right by rotating the movable plate, which is suitable for obtaining surgical fields of view during unilateral dental surgery.

[0050] (5) Simplification of fixing elements: Compared with previous operating tables, this device eliminates the need for fixing devices for the limbs of mice and rats, because experiments have shown that elastic rubber bands on the upper and lower jaws of mice and rats and stable lateral fixation are sufficient to ensure the stability of the oral position during surgery. In addition to the mouse tail fixing clamp, no other additional fixing devices are required, saving time for pre-operative preparation.

[0051] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
