Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a multi-dimensionally adjustable oxygen supply fixing device and an oxygen supply fixing method for pet ophthalmology surgery. Background Art

[0002] With the improvement of the status of companion animals in the family and the rapid development of veterinary ophthalmology technology, ophthalmic surgeries for pets such as dogs and cats (such as cataract removal, corneal transplantation, glaucoma surgery, removal of intraocular foreign bodies, eyelid plastic surgery, etc.) are becoming increasingly common and sophisticated.

[0003] Currently, ophthalmic surgery for pets is characterized by high precision, a confined operating space (small eyeball surface area), fragile tissues (cornea, lens, etc.), and relatively long operating times. Typically, ophthalmic surgery for pets is performed under general anesthesia, during which the animal's spontaneous breathing may be suppressed. Continuous, stable, and appropriately positioned oxygen supply is a rigid requirement for maintaining stable vital signs, preventing hypoxia, and ensuring anesthesia safety. To prevent unconscious movements (minor twitches or changes in body position) during surgery from catastrophically impacting delicate ophthalmic procedures, such as accidental injury to intraocular tissue by instruments, the animal's head must be fixed.

[0004] During ophthalmic surgery on pets, an independent oxygen mask is usually used, which is held by an assistant or simply fixed on the animal's head. The oxygen mask is not only prone to causing local pressure on the eyes, but is also easily displaced and caused to fall off during surgical drapes, surgical operations, or slight movement of the animal, resulting in oxygen supply interruption. Secondly, the oxygen supply pipeline and interface are easily interfered with the surgical light, blocked the surgeon's line of sight, and hindered the operation of instruments due to changes in the pet's surgical position, especially in ophthalmic surgery that requires multi-angle observation and operation. Summary of the Invention

[0005] The main purpose of the present invention is to provide a multi-dimensional adjustable oxygen supply fixing device for pet ophthalmic surgery, aiming to improve the deficiencies of the above-mentioned prior art and solve the problem that the oxygen supply mask is easily caused to local pressure on the eyes when fixed on the pet's head.

[0018] an adjusting portion, the adjusting portion having an external thread section threadably engaged with the threaded hole;

[0019] Among them, one end of the adjusting part axially passes through the threaded hole and is connected to the movable part; the adjusting part can drive the movable part to move along the axial direction of the threaded hole. When the movable part moves, the movable part pushes the first stretching arm and the second stretching arm to rotate synchronously in opposite directions around their connection point to adjust the opening and closing angle between the first stretching arm and the second stretching arm.

[0020] Optionally, two opposite side walls of the fixing bracket are respectively provided with a rod body that is easy to hold, and the surface of each rod body is provided with anti-slip grooves.

[0038] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0039] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0040] In this application, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0041] In addition, the descriptions of "first", "second", etc. in this application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0042] In pet ophthalmology surgery, an independent oxygen mask is usually used, which is held by an assistant or simply fixed on the animal's head. At the same time, in order to prevent the animal's head from moving unconsciously during the operation, it is usually necessary to wear a muzzle on its head, which is fixed by fixing the muzzle's fixing strap to the operating table.

[0043] The inventors found that if an assistant is required to hold the oxygen mask, the workload of medical staff will increase, making it difficult for the assistant to free up his hands to assist in other tasks during pet eye surgery. If the oxygen mask is fixed on the animal's head, the oxygen mask and mouthpiece themselves have weight. When the above fixing method is adopted, the gravity of the oxygen mask and mouthpiece is almost entirely applied to the pet's head (mainly the mouth, nose and cheekbone area). These areas are close to the eye surgery area. Excessive local pressure can easily compress the blood vessels and nerves around the eyes and even the eyeball itself, thereby increasing the difficulty of the operation.

[0044] Secondly, ophthalmic surgery relies on high-brightness, well-focused surgical lights (such as microscope lights and headlights). Oxygen tubes are typically suspended from the oxygen mask. When body position changes, causing the oxygen tubes to swing or shift position, they can easily cast a moving shadow within the narrow surgical field, obscuring critical anatomical structures. Furthermore, the walls of the oxygen tubes can easily reflect surgical light into the surgeon's eyes, causing glare and impairing visual clarity.

[0045] Based on this, the embodiment of the present application provides a multi-dimensional adjustable oxygen supply fixation device for pet ophthalmic surgery, see Figure 1 As shown, the multi-dimensional adjustable oxygen supply fixing device includes a mounting frame 1, an adjusting mechanism 2 and a breathing frame 3. The adjusting mechanism 2 is arranged on the mounting frame 1. The adjusting mechanism 2 includes a first arm 21, a second arm 22 and a third arm 23. The proximal end of the first arm 21 is connected to the mounting frame 1, the distal end of the first arm 21 is rotatably connected to the proximal end of the second arm 22, and the distal end of the second arm 22 is rotatably connected to the proximal end of the third arm 23; an oxygen supply mask is arranged in the breathing frame 3, and the breathing frame 3 is hung on the distal end of the third arm 23 by a fixing belt.

[0046] Specifically, the mounting frame 1 is used to support the adjustment mechanism 2. The mounting frame 1 is made of metal. Since the tensile and compressive strengths of metals (such as steel and aluminum alloys) are generally higher than those of non-metallic materials such as plastic and wood, when the mounting frame 1 supports the adjustment mechanism 2, the metal material can withstand large loads (such as gravity and lateral forces), preventing the structure from bending, breaking, or plastic deformation due to overload. Secondly, the mounting frame 1 is made of metal, which can lower the center of gravity of the multi-dimensional adjustable oxygen supply fixture for pet ophthalmic surgery, reduce the risk of tipping, and thereby improve the stability of the multi-dimensional adjustable oxygen supply fixture for pet ophthalmic surgery.

[0047] The embodiment of the present application provides a multi-dimensionally adjustable oxygen supply and fixing device for pet ophthalmic surgery. It does not require an assistant to hold the mask in hand or rely on the animal's head to bear the weight and fix it. The weight of the oxygen supply mask is mainly supported by the mounting frame 1 and the adjustment mechanism 2. The assistant does not need to be responsible for the positioning and fixing of the mask, so he can complete other auxiliary tasks, such as delivering instruments, assisting in exposing the surgical field, managing anesthesia, etc., which significantly improves the efficiency of the operation.

[0048] In this embodiment, the adjustment mechanism 2 provides partial support, preventing the entire weight of the breathing frame 3 from acting on the pet's head. This resolves the problem of localized pressure on the eyes caused by the oxygen mask being secured to the pet's head. Furthermore, the angles between the second arm 22 and the first arm 21, as well as the angles between the second arm 22 and the third arm 23, are adjustable. This allows the position of the breathing frame 3 on the X, Y, and Z axes to be adjusted based on the breed and size of the pet, as well as the surgical position. This allows the breathing frame 3 to be aligned with the pet's mouth and nose, ensuring effective oxygen supply. Furthermore, the oxygen supply tube 7 is secured to the adjustment mechanism 2, preventing it from swinging due to minor animal movements, operating table adjustments, or airflow. This prevents the overhanging oxygen supply tube 7 from casting a moving shadow within the narrow ophthalmic surgical field, ensuring that the surgical light consistently illuminates key anatomical structures and maintaining a clear and stable surgical field of view.

[0049] The embodiment of the present application provides a multi-dimensionally adjustable oxygen supply fixture for pet ophthalmic surgery. The doctor or assistant can not only adjust the oxygen supply tube 7 to a position that avoids the reflection angle of the main light path of the surgical light, but also use the adjustment mechanism 2 to block part of the reflected light, thereby reducing the possibility of the tube wall of the oxygen supply tube 7 reflecting high-brightness surgical light into the surgeon's eyes and causing glare, thereby greatly improving the surgeon's visual comfort and operating accuracy.

[0050] In the adjustment mechanism 2, the angles between the second arm 22 and the first arm 21, as well as the angles between the second arm 22 and the third arm 23, are both adjustable, relying on friction to achieve both adjustment and angle maintenance. When an external force is applied that exceeds the static friction of the second arm 22, the second arm 22 rotates. Once the second arm 22 is adjusted to a predetermined angle, the static friction of the second arm 22 maintains equilibrium, maintaining the angle between the second arm 22 and the first arm 21 at the predetermined value. Similarly, the third arm 23 can adopt a similar structural design to achieve angle adjustment.

[0051] Of course, those skilled in the art may also use locking screws, for example, screwing two locking screws into the connection between the first arm 21 and the second arm 22, and the connection between the second arm 22 and the third arm 23, respectively, to achieve locking and fixation. It should be noted that other locking methods, as long as they can achieve the technical effects disclosed in this application, are also within the scope of protection of this application. Therefore, this application does not specifically limit them.

[0052] See also Figures 1 and 2 As shown, the mounting frame 1 includes a fixed bracket 11, a telescopic member 12 and a swing member 13. The fixed bracket 11 is arranged at an angle. The telescopic member 12 is hinged on the side wall of the fixed bracket 11. One end of the swing member 13 is hinged to the upper end of the fixed bracket 11, and the other end of the swing member 13 is connected to the first arm 21. The upper end of the telescopic member 12 is movably connected to the swing member 13, and the telescopic member 12 is configured to drive the swing member 13 to rotate a predetermined angle around the hinge point between it and the fixed bracket 11 through telescopic movement.

[0053] Specifically, the telescopic member 12 is an electric push rod. Extending the telescopic member 12 pushes or retracts it, pulling the active connection point of the swinging member 13. This forces the swinging member 13 to rotate upward or downward about its upper hinge point, thereby adjusting the Z-axis position and height of the first arm 21 connected to the other end of the swinging member 13. By converting the linear displacement of the telescopic member 12 into a larger arc displacement at the end of the swinging member 13, the time required for adjustment is reduced.

[0054] In one embodiment of the present application, see Figure 2 As shown, the mounting frame 1 also includes a base 14, and the fixing bracket 11 is installed on the base 14. The base 14 includes a base body 141 and support frames 142 respectively arranged on opposite sides of the base body 141. There is an operating gap 143 between the two support frames 142, and a universal wheel 144 is provided at the bottom of each support frame 142.

[0055] Specifically, the two support frames 142 are in the shape of long strips, and the base 14 is mounted on one end of the two support frames 142 and fixedly connected to the two support frames 142. The other ends of the two support frames 142 have an operating gap. With this design, when the mounting frame 1 moves toward the operating table, the operating gap 143 reserves a certain space to accommodate the operating table support feet, so that the mounting frame 1 can be close to the operating table, avoiding the situation where the mounting frame 1 has to stop at a distant position to avoid the operating table support feet, and greatly reducing the extra space occupied by the multi-dimensional adjustable oxygen supply fixture on the side of the operating table.

[0056] In one embodiment of the present application, the angle between the base 14 and the fixing bracket 11 is 95° to 120°. Preferably, the angle between the base 14 and the fixing bracket 11 is 100°, 105° or 110°.

[0057] Specifically, the fixed bracket 11 is designed to be tilted backward, and the angle between the base 14 and the fixed bracket 11 is 95° to 120°, so that the center of gravity of the fixed bracket 11 and the telescopic member 12 and the swing member 13 installed thereon move backward relative to the support point of the base 14, thereby improving the anti-overturning ability. When the adjustment mechanism 2 extends forward, the mounting frame 1 can effectively resist the risk of overturning. Even if the medical staff pulls the oxygen mask or the adjustment mechanism 2 extends and lengthens, the mounting frame 1 can remain stable.

[0058] Secondly, the angle between the base 14 and the fixed bracket 11 is 95° to 120°. This design allows the telescopic member 12 to be vertically installed on the fixed bracket 11. When the telescopic member 12 is extended or shortened, the direction of its force always remains in the vertical direction, so that medical staff only need to control the telescopic member 12 to perform small-stroke, precise linear adjustments to drive the swing member 13 to swing rapidly around the hinge point, thereby adjusting the position height of the first arm 21 connected to the other end of the swing member 13 in the Z-axis direction. By converting the linear displacement of the telescopic member 12 into a larger arc displacement at the end of the swing member 13, the time required for adjustment is reduced.

[0059] See also Figure 3 As shown, an opening mechanism 4 is hung on the third arm 23 , and the opening mechanism 4 is connected to the third arm 23 via a connecting rope 5 .

[0060] Preferably, the expansion mechanism 4 includes a fixed part 41, an expansion assembly 42, a movable part 43 and an adjusting part 44, and a threaded hole is provided inside the fixed part 41; the expansion assembly 42 includes a first expansion arm 421 and a second expansion arm 422, and the first expansion arm 421 and the second expansion arm 422 are arranged opposite to each other and are rotatably connected to the opposite ends of the fixed part 41; the movable part 43 is located between the first expansion arm 421 and the second expansion arm 422, and the opposite ends of the movable part 43 can be slidably abutted against the inner sides of the first expansion arm 421 and the second expansion arm 422 respectively; the adjusting part 44 has an external thread section that is threadedly matched with the threaded hole.

[0061] Among them, one end of the adjusting part 44 axially passes through the threaded hole and is connected to the movable part 43; the adjusting part 44 can drive the movable part 43 to move along the axial direction of the threaded hole. When the movable part 43 moves, the movable part 43 pushes the first stretching arm 421 and the second stretching arm 422 to rotate synchronously in opposite directions around their connection point to adjust the opening and closing angle between the first stretching arm 421 and the second stretching arm 422.

[0062] Specifically, in the initial state, the external thread section of the adjusting portion 44 is screwed into the threaded hole of the fixing portion 41 , and the movable portion 43 is pulled by the adjusting portion 44 and located between the first spreading arm 421 and the second spreading arm 422 . When the adjusting part 44 is rotated, the external thread section of the adjusting part 44 and the threaded hole of the fixing part 41 generate a threaded pair motion, so that the rotational motion of the adjusting part 44 is converted into axial linear motion, thereby driving the movable part 43 connected thereto to move axially synchronously. The two ends of the movable part 43 respectively abut against the inner sides of the first stretching arm 421 and the second stretching arm 422. When the movable part 43 moves in the direction away from the fixing part 41, a lateral thrust is generated at the contact point between one end of the movable part 43 and the first stretching arm 421, and a lateral thrust is also generated at the contact point between the other end of the movable part 43 and the second stretching arm 422. The lateral thrust pushes the first stretching arm 421 and the second stretching arm 422 to rotate synchronously in opposite directions around their connection points with the fixing part 41, and the first stretching arm 421 and the second stretching arm 422 gradually open, thereby opening the pet's eyelids; when the movable part 43 moves in the direction close to the fixing part 41, the first stretching arm 421 and the second stretching arm 422 are retracted.

[0063] With the above-mentioned structural design, the rotational motion is converted into axial linear motion through the threaded pair. During the axial movement of the movable part 43, the axial thrust is converted into lateral thrust through its two ends respectively connected to the first expansion arm 421 and the second support arm, thereby pushing the first expansion arm 421 and the second support arm to rotate synchronously in opposite directions around the hinge point of the fixed part 41, thereby realizing the opening or closing of the expansion arm.

[0064] When opening a pet's fragile eyelids, the structure described above can prevent damage to the eyelid tissue caused by excessive initial force or excessive opening speed. Through fine-tuning the thread, medical personnel can slowly and gradually increase the opening range, allowing the eyelid tissue to adapt and gradually achieve the required minimum effective opening.

[0065] The first stretching arm 421 and the second stretching arm 422 are symmetrically distributed about the adjusting part 44, and the distance between the connection point between the movable part 43 and the adjusting part 44 and the connection point between the movable part 43 and the first stretching arm 421 is equal to the distance between the connection point between the movable part 43 and the adjusting part 44 and the connection point between the movable part 43 and the second stretching arm 422.

[0066] Specifically, the movable portion 43 functions as a rigid unit, with both ends of the movable portion 43 simultaneously and directly abutting the first opening arm 421 and the second support arm. When the movable portion 43 moves axially, it simultaneously applies forces to the first opening arm 421 and the second support arm. The forces exerted by the movable portion 43 on the first opening arm 421 and the second support arm are equal in magnitude and opposite in direction, thereby driving the first opening arm 421 and the second support arm to rotate at the same angle and in opposite directions. When opening a pet's eyelids, this prevents discomfort to the pet due to excessive force on one side, thereby improving operational safety.

[0067] Preferably, two opposite side walls of the fixing bracket 11 are respectively provided with a rod body 6 for easy gripping, and the surface of each rod body 6 is provided with anti-slip grooves.

[0068] Preferably, the breathing frame 3 is provided with a plurality of insertion ports for allowing the laces to pass through.

[0069] In addition, the present invention also provides an oxygen supply fixing method for the multi-dimensional adjustable oxygen supply fixing device for pet ophthalmological surgery, see Figure 4 As shown, the oxygen supply fixation method includes the following steps:

[0070] S1, the mounting frame 1 is moved to the front of the operating table;

[0071] S2, the telescopic member 12 performs telescopic motion to drive the swing member 13 to rotate a predetermined angle around the hinge point between the swing member 13 and the fixed bracket 11;

[0072] S3, sequentially adjusting the angle between the second arm 22 and the first arm 21 and the angle between the second arm 22 and the third arm 23, so that the adjustment mechanism 2 is unfolded and extended to a predetermined position;

[0073] S4. The oxygen supply box is set on the mounting frame 1. The oxygen supply pipe 7 connected to the oxygen supply box is arranged along the extending direction of the swing member 13, the first arm 21, the second arm 22 and the third arm 23 and is hung on the swing member 13, the first arm 21, the second arm 22 and the third arm 23 by a fixing belt;

[0074] S5. The breathing frame 3 is hung on the distal end of the third arm 23. The breathing frame 3 is worn on the pet's head, and the oxygen supply mask located in the breathing frame 3 is aligned with the pet's face to supply oxygen.

[0075] In summary, the multi-dimensionally adjustable oxygen supply fixture for pet ophthalmic surgery proposed in the present invention includes a mounting frame 1, an adjustment mechanism 2, and a breathing frame 3. The adjustment mechanism 2 is disposed on the mounting frame 1 and includes a first arm 21, a second arm 22, and a third arm 23. The proximal end of the first arm 21 is connected to the mounting frame 1, the distal end of the first arm 21 is rotatably connected to the proximal end of the second arm 22, and the distal end of the second arm 22 is rotatably connected to the proximal end of the third arm 23. An oxygen mask is disposed within the breathing frame 3, which is hung on the distal end of the third arm 23 via a fixing strap. This design allows the adjustment mechanism 2 to provide partial support, preventing the entire weight of the breathing frame 3 from acting on the pet's head, thereby resolving the problem of localized pressure on the eyes caused by the oxygen mask being fixed to the pet's head. Secondly, the position of the breathing frame 3 on the X-axis, Y-axis and Z-axis can be adjusted by adjusting the angle between the second arm 22 and the first arm 21 and the angle between the second arm 22 and the third arm 23, so that the breathing frame 3 can be aligned with the mouth and nose of the pet to ensure effective oxygen supply. At the same time, the oxygen supply tube 7 is fixed on the adjustment mechanism 2, so that the position of the oxygen supply tube 7 will not swing arbitrarily due to the animal's micro-movement, operating table adjustment or airflow, avoiding the hanging oxygen supply tube 7 from casting a moving shadow in the narrow ophthalmic surgical field, ensuring that the surgical light can always illuminate the key anatomical structures without obstruction, and ensuring a clear and stable surgical field of view.
