Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of injection fixators, in particular to an extraocular muscle injection fixator. Background Technique
[0002] The extraocular muscles are striated muscles that control eye movement. Each eye has 6 of them. According to their running directions, they are divided into rectus muscles and oblique muscles. There are 4 rectus muscles, namely the superior rectus, inferior rectus, medial rectus, and lateral rectus; the two oblique muscles are the superior oblique muscle and the inferior oblique muscle. All four rectus muscles originate from the common tendon ring around the optic nerve foramen at the apex of the orbit. The muscle fibers of each muscle form a bundle and surround the optic nerve and spread forward respectively, attaching to the sclera in front of the equator of the eyeball at different distances from the corneal margin.
[0003] When various congenital or acquired factors cause extraocular muscle contracture and intramuscular drug injection is required, ordinary surgical forceps are usually used to clamp the muscle. The muscle is not firmly fixed. Moreover, since the muscle is closely attached to the sclera, it is extremely easy to damage the sclera. And during a long surgical procedure, it is impossible to well control the clamping force by manually holding the surgical forceps, which is likely to cause damage to the extraocular muscle. Also, when the surgical forceps shake due to manual factors and other reasons, the surgical forceps are also likely to cause harm to the patient. Content of the Utility Model
[0004] The purpose of the utility model is to provide an extraocular muscle injection fixator to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: an extraocular muscle injection fixator, including: a surgical forceps and a fixing ring, and an installation frame is rotatably installed on the surgical forceps;
[0006] It further includes:
[0007] A lateral displacement assembly, the lateral displacement assembly is arranged on the installation frame, and the lateral displacement assembly is used to drive the surgical forceps to move laterally relative to the fixing ring to adjust the lateral position of the surgical forceps;
[0008] A longitudinal displacement assembly, the longitudinal displacement assembly is arranged on the lateral displacement assembly, and the longitudinal displacement assembly is used to drive the surgical forceps to move longitudinally relative to the fixing ring to adjust the longitudinal position of the surgical forceps;
[0009] A fixing assembly, the fixing assembly is arranged on the surgical forceps, and the fixing assembly is used to fix the opening angle of the surgical forceps when the surgical forceps clamp the muscle.
[0010] Preferably, the lateral displacement assembly includes a first slider fixedly installed on the installation frame, a first lead screw threadedly sleeved on the first slider, a first slide rail slidably arranged on the top of the first slider and rotatably connected to the first lead screw, and a first motor fixedly installed on the side of the first slide rail and connected to the first lead screw.
[0011] Preferably, the longitudinal displacement assembly includes a second slider fixedly installed on the top of the first slide rail, a second lead screw threadedly sleeved on the second slider, a second slide rail slidably disposed on the top of the second slider and rotatably connected to the second lead screw, and a second motor fixedly installed on the side of the second slide rail and connected to the second lead screw.

[0013] Preferably, a fixing rod is fixedly installed on the top of the second slide rail, and one end of the fixing rod away from the second slide rail is fixedly connected to a fixing ring.
[0014] Preferably, straps and connectors are respectively installed at both ends of the fixing ring, a buckle is slidably disposed on the strap, and a slot matching the buckle is provided on the connector.
[0015] Preferably, the surgical forceps are provided with forceps jaws, the forceps jaws are serrated notches, and the notches on the two forceps jaws mesh with each other.
[0016] The utility model has at least the following beneficial effects:
[0017] The surgical forceps can be worn on the patient's head through the provided fixing ring, eliminating the need for the doctor to hold the surgical forceps all the time. Then, through the provided transverse displacement assembly and longitudinal displacement assembly, the surgical forceps can be driven to move horizontally and vertically relative to the fixing ring, facilitating the adjustment of the position of the surgical forceps. Thus, it is convenient for the doctor to clamp and fix the extraocular muscles of different patients through the surgical forceps, achieving precise adjustment of the position of the surgical forceps. When the doctor clamps the extraocular muscles of the patient through the surgical forceps, the opening angle of the surgical forceps can be fixed through the fixing assembly. Compared with the prior art, where the doctor needs to hold it manually, during a long operation, an accidental event may occur, causing damage to the patient. In the utility model, during the operation, the relative static state between the surgical forceps and the patient can be ensured, reducing the possibility of accidents. After the surgical forceps clamp the extraocular muscles, tighten the bolt, and the doctor can release both hands to perform other operations of the surgery, saving manpower and increasing the safety of the surgery.

[0025] Please refer to Figures 1-5 , the present utility model provides a technical solution:
[0026] Embodiment 1,
[0027] An external ocular muscle injection fixator, comprising: a surgical forceps 1 and a fixed ring 7. The mounting frame 2 is rotatably mounted on the surgical forceps 1. The surgical forceps 1 and the patient are fixed through the fixed ring 7, avoiding scratching the patient by the surgical forceps 1 caused by the unconscious shaking of the patient or the movement caused by the doctor's operation error;
[0028] A lateral displacement assembly 3, the lateral displacement assembly 3 is arranged on the mounting frame 2, and the lateral displacement assembly 3 is used to adjust the position of the surgical forceps 1 horizontally, and can relatively precisely control the horizontal movement of the surgical forceps 1 relative to the fixed ring;
[0029] A longitudinal displacement assembly 4, the longitudinal displacement assembly 4 is arranged on the lateral displacement assembly 3, and the longitudinal displacement assembly 4 is used to adjust the position of the surgical forceps 1 longitudinally, and can relatively precisely control the longitudinal movement of the surgical forceps 1 relative to the fixed ring;
[0030] A fixing assembly 5, the fixing assembly 5 is arranged on the surgical forceps 1, and the fixing assembly 5 is used to fix the opening angle of the surgical forceps 1 when the surgical forceps 1 clamps the muscle.
[0031] The lateral displacement assembly 3 includes a first slider 304 fixedly installed on the mounting bracket 2, a first lead screw 303 threadedly engaged with the first slider 304, a first slide rail 301 slidably disposed on the top of the first slider 304 and rotatably connected to the first lead screw 303, and a first motor 302 fixedly installed on the side of the first slide rail 301 and connected to the first lead screw 303, which can more accurately control the lateral movement of the surgical forceps 1.
[0032] The longitudinal displacement assembly 4 includes a second slider 404 fixedly installed on the top of the first slide rail 301, a second lead screw 403 threadedly engaged with the second slider 404, a second slide rail 401 slidably disposed on the top of the second slider 404 and rotatably connected to the second lead screw 403, and a second motor 402 fixedly installed on the side of the second slide rail 401 and connected to the second lead screw 403, which can more accurately control the longitudinal movement of the surgical forceps 1.
[0033] A fixing rod 6 is fixedly installed on the top of the second slide rail 401. One end of the fixing rod 6 away from the second slide rail 401 is fixedly connected to a fixing ring 7. The surgical forceps 1 and the patient are fixed through the fixing ring 7, avoiding scratching the patient caused by the unconscious shaking of the patient or the accidental movement of the doctor during the operation.
[0034] Both ends of the fixing ring 7 are respectively installed with a strap 8 and a joint 10. A buckle 9 is slidably disposed on the strap 8, and a slot matching the buckle 9 is provided on the joint 10.
[0035] The surgical forceps 1 are provided with forceps jaws 101. The forceps jaws 101 are serrated notches, and the notches on the two forceps jaws 101 are meshed with each other. When the surgical forceps 1 clamp the extraocular muscle, they can be clamped stably without slipping. A soft sleeve can be installed on the forceps jaws 101 to prevent scratching the patient.
[0036] When performing an extraocular muscle injection surgery, first put the fixing ring 7 on the patient's head, and fasten the buckle 9 to the joint 10 by adjusting the length of the strap 8 to fix the fixing ring 7. At this time, start the first motor 302 and the second motor 402 respectively. By driving the rotation of the first lead screw 303 and the second lead screw 403, move the first slider 304 and the second slider 404 to appropriate positions, so that the horizontal and vertical positions of the surgical forceps 1 can be adjusted, facilitating the doctor to clamp and fix the extraocular muscles at different positions of different patients through the surgical forceps 1, and then complete the injection operation. Moreover, through the operation of the first motor 302 and the second motor 402, the movement of the surgical forceps 1 can be precisely and subtly controlled, avoiding additional damage to the patient due to the narrow surgical space. In addition, the hand-held surgical forceps 1 are fixed on the fixing ring 7 and will not shake due to the doctor's manual operation to cause harm to the patient's eyes. Through the set forceps jaws 101, the clamping stability can be maintained when the surgical forceps 1 clamp the extraocular muscles, preventing the phenomenon of slipping.

[0038] When the surgical forceps 1 clamp the extraocular muscles, first unscrew the bolt 502. When clamping, the surgical forceps 1 drive the connecting rod 501 to rotate. At this time, tighten the bolt 502 so that the two connecting rods 501 are fixed and cannot rotate, thereby fixing the opening angle of the surgical forceps 1, preventing the doctor from holding the surgical forceps 1 for a long time during a long operation, resulting in uneven force application, causing excessive force to damage the extraocular muscles or insufficient force to cause the extraocular muscles to slip.
