[0031] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The utility model comprises a support, a movable arm and a clamping frame. When in use, the support is fixed under the operating table, and the movable arm is moved to drive the clamping frame clamping the instrument tray to move and stay at a set position without being placed on the patient.

[0033] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0034] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] Ophthalmic surgery is different from surgery on other parts of the human body in that the ophthalmic surgery area is on the head and the operating area is limited. For local surgery on other parts of the torso, a small surgical instrument tray can be placed on the patient's body for easy access during surgery. However, the torso near the head only has the neck, which is not suitable for placing the instrument tray to avoid compressing the blood vessels or trachea. If it is placed on the upper body, it is too far away and not suitable for quick access. One purpose of the technical solution of the utility model is to provide an auxiliary bracket for an operating table that can be conveniently placed during surgery and conveniently moved when necessary.

[0036] Figures 1 to 6 According to an embodiment of the utility model, an auxiliary support for an ophthalmic operating table 100 is provided, comprising

[0037] Support 1: clamped under the operating bed 100, including a support rod 2 with adjustable length and clamping rods 11 arranged at both ends of the support rod 2. The support rod 2 is extended to press the clamping rod 11 against the frames on both sides of the operating bed 100; a movable arm 3 is provided on the clamping rod 11; in this embodiment, in order to facilitate the adjustment of the position, the support 1 is fixed under the operating bed 100 in the above-mentioned manner. The advantage of using this method is that it does not occupy ground space like a floor-standing stand.

[0038] In some embodiments, the clamping rod 11 has a C-shaped cross section to be sleeved on the bottom brackets on both sides of the operating bed 100. One side wall of the C-shape is hinged with the support rod 2, and a hand-tightened bolt 121 is provided through the other side. The hand-tightened bolt 121 rotates to tightly contact the side of the bottom bracket of the operating bed 100. Specifically, the purpose of the clamping rod 11 is to bear the load of the upper movable arm 3, provide a fulcrum for the movable arm 3, and fix the entire device under the operating bed 100. Therefore, the overall structure of this embodiment is two C-shaped components with openings facing upwards that can adjust the distance between each other. The C-shaped components adjust the internal size of the C-shaped opening by moving the hand-tightened bolt 121 to achieve the clamping of the lower bracket of the operating bed 100; wherein, one end of the hand-tightened bolt 121 inside the clamping rod 11 is rotatably provided with a clamping plate at the end to expand the contact area, improve the friction force, and avoid damaging the bracket of the operating bed 100.

[0039] In some embodiments, the support rod 2 includes two coaxially arranged screw rods 21 with opposite threads, and the two screw rods 21 are connected by a screw sleeve 22 with corresponding threads formed inside. The screw sleeve 22 rotates to make the screw rods 21 move away from or closer to each other. In this embodiment, the method for adjusting the spacing of the clamping rods 11 is to use the screw rods 21. Since the two screw rods 21 have opposite threads and the screw sleeve 22 also has threads that match the screw rods 21, when the screw sleeve 22 rotates in one direction, the two screw rods 21 will move inward or outward synchronously, thereby achieving the extension or shortening of this structure.

[0040] It can also be arranged in the following manner: two nuts are flexibly connected at both ends of the screw sleeve 22, and the nuts can rotate radially but can only slide slightly axially. The advantage of this structure is that it reduces the difficulty of rotation caused by fixing the screw sleeve 22 during use, but the processing cost of this structure is higher.

[0041] In order to adapt to different operating table structures, in some embodiments, as shown in the attached manual Figure 6 As shown, the clamping rod 11 is a hollow square tube, the middle section of the square tube is cut off, and an inner tube 112 with an outer diameter smaller than the inner diameter of the square tube is inserted therein, the inner tube 112 is provided with a plurality of through holes 111 along the radial direction, and the clamping rod 11 is also provided with a plurality of through holes 111 correspondingly, when the inner tube 112 slides in the clamping rod 11, after the through holes 111 on different rods are aligned, a movable pin is inserted, thereby limiting the relative movement of the clamping rod 11 and the inner tube 112, and through this structure, the overall length of the clamping rod 11 can be adjusted; the design purpose of this structure is to make the device as shown in the attached manual Figure 7 ~Instructions attached Fig. 9 The armrest lengths of different operating tables: Since some operating tables can be partially bent, and this device is mainly used for eye surgery, it needs to be fixed to the front half of the operating table. This part is affected by the different types of operating tables, and the armrest lengths are different. Therefore, the above technical solution can be adapted to different operating tables.

[0042] The movable arm 3 includes a straight arm 31, a cantilever arm 32 and a swing arm 33;

[0043] The straight arm 31 is installed vertically, with one end arranged on the support 1; the arrangement method can be that the support 1 forms a tapered hole, and the lower part of the straight arm 31 is fixed to the support 1 through a tapered fit; or it can be that the support 1 simply has a socket hole, and the straight arm 31 is directly inserted and fixed.

[0044] In some embodiments, a height adjustment element 311 is provided on the straight arm 31, and the height adjustment element 311 includes an inner adjustment piece 3111 and an outer fastener 3112. The inner adjustment piece 3111 is sleeved on the straight arm 31 and abuts against the bottom of the cantilever 32; the outer fastener 3112 is matched with the outer thread of the inner adjustment piece 3111, and the outer fastener 3112 rotates to change the friction between the inner adjustment piece 3111 and the cantilever 32. Specifically, the inner adjustment piece 3111 is formed with a plurality of notches along the axial direction, and the inner adjustment piece 3111 has a taper. When the outer fastener 3112 moves (tightens) along the thread, the taper can be used to tighten the inner diameter of the inner adjustment piece 3111, thereby making the inner surface of the inner adjustment piece 3111 firmly attached to the straight arm 31. This fixing method relies on its own elastic deformation to fit, has a large contact area, and has a strong friction. When the cantilever 32 moves downward, it plays a supporting role.

[0045] The cantilever 32 is arranged on the straight arm 31, and can move along the length direction of the straight arm 31, and rotate with the straight arm 31 as the center of the circle; viewed from the top, the straight arm 31 provides a turning radius, and more importantly, the structure composed of the straight arm 31 and the swing arm 33 is combined into a sector with a variable radius in the plane, making this embodiment more flexible.

[0046] Optionally, the cantilever 32 is hinged to one end of the straight arm 31, and is provided with a cantilever fixing element 321, which inhibits or releases the rotation of the cantilever 32 relative to the straight arm 31 by moving along the radial direction of the straight arm 31. Specifically, the cantilever fixing element 321 can be a bolt, which is tightly pressed against the surface of the straight wall by rotation to increase the rotation friction, thereby playing the role of fixing the rotation of the cantilever 32.

[0047] The swing arm 33 is hinged at one end of the cantilever 32, and the cantilever 32 rotates around the hinge point between the cantilever 33 and the swing arm 33. The cantilever 32 can swing up and down relative to the horizontal plane and maintain the angle after the swing. The up and down swing structure of the cantilever 32 has various forms, such as setting a hinge joint that can move up and down, and changing the friction force at the hinge by applying pressure to the hinge point, such as bolt adjustment.

[0048] In some embodiments, the swing arm 33 includes an upper swing member 331 and a lower swing member 332. The cantilever 32 is provided with a telescopic adjustment element 333 that abuts against the bottom of the upper swing member 331; the arrangement is such that there is an angle between the telescopic adjustment element 333 and the upper swing member 331; the telescopic adjustment element 333 is extended or shortened to make the upper swing member 331 swing upward or downward, thereby making the cantilever 32 swing up and down. Specifically, the upper swing member 331 and the lower swing member 332 are as shown in the attached figure. Figure 4 As shown, the head and tail parts are hinged to form a parallelogram structure. The reason for adopting this structural solution is that the clamping frame 4 is set at the end of the swing arm 33. The swing arm 33 swings up and down, and the clamping frame 4 does not change its horizontal state. Therefore, the up and down movement does not need to adjust the state of the clamping frame 4. It is convenient to adjust the instrument tray with surgical instruments. The telescopic adjustment element 333 can be a bolt, which is set on the lower swing member 332 through threaded cooperation, and the length of the extension between the upper swing member 331 and the lower swing member 332 is changed by rotation.

[0049] The clamping frame 4 is arranged at the end of the swing arm 33 and can rotate around the axial direction of the swing arm 33; it includes a first clamping member 41 and a second clamping member 42 whose distances can be adjusted to clamp the medical tray. The two clamping rods 11 can be slidably matched and connected by an elastic element so that the two always maintain a tendency to approach each other, and can clamp various instrument trays.

[0050] The swing arm 33 drives the clamping frame 4 to move in three axes within a limited area in space and stay at any position in the area, which is convenient for use during ophthalmic surgery.

[0051] It also includes a control switch 5, which controls the corresponding tension elements on the cantilever and the swing arm, and the tension elements switch the cantilever, the swing arm and the support frame between a relatively fixed state and a relatively movable state. Specifically, the control switch 5 is arranged on the clamping frame 4, and is connected to the tension element by wire pulling, hydraulic pressure, etc. Its structure can refer to the driving method of the existing bicycle speed change or brake system. The tension element includes a structure similar to a brake pad and a spring. In normal times, the spring drives the brake pad to hold the movable shaft tightly to play a fixing role. When the control switch 5 is pressed (by hand holding), the brake pad is loosened to achieve the movable effect.
