DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] The following describes in detail a technical solution of a strabismus surgical instrument for pulling muscles during surgery according to various embodiments of the present invention in conjunction with the accompanying drawings.

[0039] Reference Figures 1 to 9 As shown, an embodiment of the present invention provides a strabismus surgical instrument for pulling muscles during surgery, including a horizontal plate 1, wherein four legs 11 are provided at the bottom of the horizontal plate 1; a slide groove 13 is provided in the horizontal plate 1, wherein a horizontal moving structure 2 is provided in the slide groove 13, wherein the horizontal moving structure 2 and the slide groove 13 are slidably matched, an angle clamping structure 3 is provided on the horizontal moving structure 2, wherein the angle clamping structure 3 and the horizontal moving structure 2 are rotatably connected, and a distance adjustment structure 4 for pulling the muscle distance is provided on the angle clamping structure 3, wherein the distance adjustment structure 4 and the angle clamping structure 3 are slidably matched.

[0040] When stretching the patient's muscles, the horizontal plate 1 is placed on the operating table on which the patient lies by means of the four legs 11 .

[0041] In this embodiment, the horizontal moving structure 2 includes a moving plate 21, and sliders 22 are respectively provided at both ends of the moving plate 21. The moving plate 21 is slidably connected in the slide groove 13 through two sliders 22, one of the sliders 22 is provided with two first sockets 23 arranged at equal intervals, and the horizontal plate 1 is provided with a plurality of second sockets 24 arranged at equal intervals, and each of the first sockets 23 is provided with a connecting pin 25 that is plugged into the second socket 24.

[0042] The movable plate 21 can be moved horizontally in the slide groove 13 through two sliders 22. When the patient undergoes strabismus surgery, the movable plate 21 can be adjusted to the left or right side of the horizontal plate 1 according to the patient's surgical needs, so as to perform strabismus surgery on the patient's left eye or right eye. After the position of the movable plate 21 is determined, the corresponding connecting pin 25 is plugged into the first socket 23 and the second socket 24, so as to fix the position of the movable plate 21.

[0043] In this embodiment, the angle clamping structure 3 includes a vertical rod 31 vertically arranged on the movable plate 21, and the vertical rod 31 extends to the bottom of the horizontal plate 1. The vertical rod 31 is provided with a plurality of equally spaced mounting circular grooves 32, and each mounting circular groove 32 is provided with a resistance ball 33, and the resistance ball 33 is slidably engaged with the mounting circular groove 32. The resistance ball 33 is provided with a resistance spring 34, and the resistance spring 34 is connected to the mounting circular groove 32. The vertical rod 31 is provided with a slidably engaged ring 35, and the ring 35 is provided with a rotating circular groove 38 that is clamped with the resistance ball 33. The ring 35 is provided with a horizontally arranged sliding frame 36, and the side wall of the vertical rod 31 located at the ring 35 is provided with a snap ring 311, and the ring 35 is provided with a ring groove that rotatably engages with the snap ring 311. The setting of the clamping ring 311 ensures that when the vertical rod 31 rotates on the ring 35, the clamping ring 311 rotates in the clamping groove, thereby ensuring that the position of the vertical rod 31 does not move downward when the vertical rod 31 rotates, thereby ensuring the accuracy of the operation.

[0044] In this embodiment, when the circular ring 35 rotates on the vertical rod 31 , the abutting balls 33 rotate in two adjacent rotating circular grooves 38 .

[0045] When adjusting the large angle position of the muscle pulling hook 423, the rotating ring 35 makes the rotating circular groove 38 on the ring 35 rotate on the abutting ball 33, thereby adjusting the angle position of the sliding frame 36 on the ring 35. After the position of the muscle pulling hook 423 is determined, the abutting spring 34 will make the abutting ball 33 abut in the corresponding rotating circular groove 38, thereby realizing the fixed position of the ring 35 on the vertical rod 31; when pulling, muscles at multiple angles can be pulled:

[0046] Horizontal pulling:

[0047] Medial rectus muscle: Located inside the eyeball, it causes the eyeball to rotate toward the nose (inside) when contracted. When correcting esotropia or adjusting the horizontal position of the eyeball, it is often necessary to stretch and adjust it. By stretching in the horizontal direction, the tension and position of the medial rectus muscle can be adjusted to achieve the purpose of correcting the eye position.

[0048] Lateral rectus muscle: Located on the outside of the eyeball, its function is to rotate the eyeball to the temporal side (outside). For patients with exotropia, it is often necessary to pull the lateral rectus muscle horizontally during surgery to change the balance of its muscle strength and restore the eyeball to its normal position.

[0049] Vertical pulling:

[0050] Superior rectus muscle: Located above the eyeball, its main function is to rotate the eyeball upward, and it also has the functions of inward rotation and inward rotation. In the surgical treatment of vertical strabismus, especially hypertropia, it is often necessary to pull the superior rectus muscle vertically to adjust the balance of power between it and other extraocular muscles and correct the abnormal vertical position of the eyeball.

[0051] Inferior rectus muscle: Located below the eyeball, it can rotate the eyeball downward and also has a certain degree of external rotation and external rotation. When conditions such as hypotropia occur, the inferior rectus muscle may need to be pulled vertically to adjust the eyeball position and improve the strabismus condition.

[0052] Pulling in oblique direction:

[0053] Superior oblique muscle: Its course is rather special, from the upper inner part of the eyeball to the upper back and outer part. Its main function is to rotate the eyeball inward, downward and outward. In some special types of strabismus, such as rotational strabismus or strabismus surgery with hyperfunction or deficiency of the superior oblique muscle, it is necessary to adjust the strength and position of the superior oblique muscle by pulling it in an oblique direction to correct the abnormal rotation of the eyeball and the strabismus angle.

[0054] Inferior oblique muscle: Located on the lower and outer sides of the eyeball, it runs diagonally from the posterior medial side of the eyeball to the anterior and lateral side. Its main function is to cause the eyeball to rotate outward, upward, and externally. When the inferior oblique muscle dysfunction causes strabismus, such as hypertropia caused by inferior oblique muscle hyperactivity, the inferior oblique muscle needs to be pulled obliquely during surgery to weaken or strengthen it, in order to restore the balance of the extraocular muscles and correct the strabismus.

[0055] In this embodiment, the distance adjustment structure 4 includes a horizontal adjustment mechanism 41 and an angle adjustment mechanism 42 . The horizontal adjustment mechanism 41 moves horizontally in the slide frame 36 , and the angle adjustment mechanism 42 is rotatably connected to the horizontal adjustment mechanism 41 .

[0056] In this embodiment, the horizontal adjustment mechanism 41 includes a horizontal adjustment screw rod 411 and a horizontal adjustment plate 412. A sliding groove 37 is provided in the sliding frame 36. Sliding blocks 413 are respectively provided at both ends of the horizontal adjustment plate 412. The horizontal adjustment plate 412 is slidably connected in the sliding groove 37 through two sliding blocks 413. The horizontal adjustment screw rod 411 is horizontally rotatably connected to the sliding frame 36. A knob 414 is provided at the end of the horizontal adjustment screw rod 411. The horizontal adjustment screw rod 411 and the sliding block 413 are threadedly connected. A numerical mark 39 is provided on the top of the sliding frame 36.

[0057] During muscle stretching, the knob 414 is turned and the horizontal adjustment screw 411 is rotated on the slide frame 36, which will drive the horizontal adjustment plate 412 to move horizontally in the slide slot 37 through the two sliding blocks 413, thereby driving the position of the muscle stretching hook 423 to stretch horizontally. The slide frame 36 is provided with a numerical mark 39. During the stretching process, the distance value of the muscle stretching can be known in real time. The doctor can accurately control the muscle stretching distance, such as accurately stretching the muscle 1 mm or 2 mm according to the patient's condition and surgical needs, to avoid excessive or insufficient stretching; rotating the horizontal adjustment screw 411 can achieve small-scale, high-precision adjustments, and the doctor can make fine adjustments at any time according to the actual situation during the operation, such as changes in muscle tension, tissue reactions, etc. The numerical mark 39 provides a quantitative basis for fine-tuning, so that the doctor knows the amplitude of each adjustment and ensures accurate operation.

[0058] In this embodiment, the angle adjustment mechanism 42 includes a universal ball 421, a lever 422 and a muscle pulling hook 423. A rotating cavity is provided in the horizontal adjustment plate 412. The universal ball 421 is rotatably connected in the rotating cavity. The lever 422 is vertically connected to the top of the universal ball 421. The muscle pulling hook 423 is connected to the bottom of the universal ball 421.

[0059] During muscle pulling, pulling the lever 422 can cause the universal ball 421 to rotate in the rotating cavity, thereby driving the angle position of the muscle pulling hook 423 to rotate. The angle change of the muscle pulling hook 423 has the following advantages:

[0060] Angle traction: It allows doctors to flexibly adjust the angle of the muscle traction hook 423 in multiple dimensions according to the specific position, direction and traction requirements of the muscles during the operation, to achieve precise traction and better meet the complex requirements of different strabismus surgeries.

[0061] Real-time fine-tuning: During the operation, the doctor can make real-time fine-tuning of the angle of the muscle pulling hook 423 by pulling the lever 422 at any time according to the actual operation situation and observed tissue changes, so as to ensure that the pulling force and direction are always in the best state.

[0062] Improved visual field: Rotating the angle of the muscle retraction hook 423 can enable the doctor to observe the surgical site from different angles, avoiding the obstruction of the line of sight due to muscles or other tissues, and helping to more clearly see the relationship between muscles and surrounding tissues, as well as the progress of the surgical operation.

[0063] Reasonable use of space: When performing surgery in a narrow space such as the eye, by adjusting the angle of the muscle retraction hook 423, the limited operating space can be more reasonably used, so that surgical instruments can enter the surgical area more smoothly and reduce mutual interference between instruments.

[0064] Precise avoidance: The muscle pulling hook 423 can be placed in a suitable position more accurately, and can better avoid surrounding blood vessels, nerves and other important tissues when pulling the muscles, thereby reducing the risk of accidental damage to these tissues during the operation.

[0065] Uniform stretching: By flexibly adjusting the angle, the pulling force can be distributed more evenly, avoiding excessive local force that causes excessive stretching or tearing of muscle tissue, which is beneficial to protecting the normal structure and function of the muscles.

[0066] In this embodiment, a threaded section is provided at the top of the muscle pulling hook 423 , and the muscle pulling hook 423 is threadedly connected to the bottom position of the universal ball 421 through the threaded section.

[0067] During muscle pulling, the muscle pulling hook 423 can be detachably mounted on the bottom of the universal ball 421 through the threaded section. In actual surgery, muscle pulling hooks 423 of different shapes, sizes or angles may be used according to different surgical requirements and muscle pulling conditions. The detachable threaded section design allows for convenient and quick replacement of a suitable pulling hook without replacing the entire instrument, thereby improving the efficiency and flexibility of surgical operations.

[0068] Convenient cleaning: Cleaning and disinfection of surgical instruments are essential to prevent cross infection. The detachable design allows the muscle retractor hook 423 and the universal ball 421 to be cleaned separately, which can more thoroughly remove contaminants such as blood and tissue fragments on the surface and in the gaps of the instruments, ensure the cleanliness of the instruments, and reduce the risk of infection.

[0069] Individual replacement of parts: During use, the muscle retraction hook 423 or the universal ball 421 may need to be replaced due to wear, damage, etc. The detachable design allows only the damaged parts to be replaced without replacing the entire device, which not only saves costs, but also can restore the normal use of the device in time, thereby improving the service life and economy of the device.

[0070] In this embodiment, a threaded interference screw 424 is provided on the horizontal adjustment plate 412 , and a semicircular interference plate 425 is provided on the interference screw 424 . The semicircular interference plate 425 slides in the rotation cavity.

[0071] After the universal ball 421 determines the angular position of the muscle traction hook 423, the rotatable interference screw 424 can be rotated on the horizontal adjustment plate 412, thereby driving the position of the semicircular interference plate 425 to move horizontally in the rotating cavity, so that the semicircular interference plate 425 is in contact with the universal ball 421, and the position of the universal ball 421 is fixed in the rotating cavity, thereby fixing the position of the muscle traction hook 423, preventing the muscle traction hook 423 from shaking or moving during the muscle traction process, thereby affecting the safety of muscle traction.

[0072] In this embodiment, a retractable support rod 12 is provided at the bottom of each support leg 11 , a plurality of connection holes 14 arranged at equal intervals are provided on the support rod 12 , and a plug-in rod 15 plugged into the connection hole 14 is provided on the support leg 11 .

[0073] Before pulling the muscles, it is necessary to determine the position height of the muscle pulling hook 423 and the patient's eyes. At this time, the position height of the support rod 12 on the support leg 11 can be adjusted by pulling out the connecting rod 15, thereby adjusting the position of the muscle pulling hook 423 and the eyes. After the position height of the muscle pulling hook 423 and the eyes is determined, the connecting rod 15 can be plugged into the corresponding connecting hole 14 to fix the position of the support rod 12 and the support leg 11. When performing strabismus surgery, the position height of the muscle pulling hook 423 can be adjusted in real time according to the different head positions of the patients, so as to be suitable for strabismus surgery operations on different types of patients.

[0074] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
