Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, in particular to an eyeball simulation device for practicing strabismus surgery. Background Art

[0002] With the continuous development and advancement of medical technology, ophthalmic surgical techniques are also constantly innovating and improving. Strabismus, a common eye disease, often occurs in childhood, so most patients undergoing strabismus surgery are children. To improve surgical success rates and reduce surgical risks, doctors require extensive simulation training before actually operating on patients.

[0003] Currently, strabismus Wetlab has been launched in my country. By simulating real surgical environments and conditions, doctors can practice in a safe environment, familiarize themselves with the use of surgical instruments and operating techniques, and master the correct surgical steps and precautions. However, the eye model commonly used in strabismus Wetlab is a pig eye, which is obtained by butchers at slaughterhouses, making it difficult to preserve the extraocular muscles intact. This makes it difficult for learners to truly experience extraocular muscle surgery during the Wetlab practice. Therefore, an eye simulator that can realistically simulate eye movement and structure is of great significance for strabismus surgery practice. Utility Model Content

[0004] In order to solve the above problems, the utility model proposes an eyeball simulation device for practicing strabismus surgery.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides an eyeball simulation device for practicing strabismus surgery, comprising a support frame, the upper end of the support frame being sleeved on a support seat, the upper end of the support seat being provided with a mounting groove, the upper end of the support frame being provided with a false eyeball, the false eyeball being arranged in the mounting groove, the false eyeball being detachably provided with a biological tissue bionic sleeve, the biological tissue bionic sleeve being provided with an interlayer, the upper end of the inner part of the interlayer being provided with a superior rectus muscle, the lower end of the inner part of the interlayer being provided with an inferior rectus muscle, the inner left side of the interlayer being provided with a lateral rectus muscle, and the inner right side of the interlayer being provided with a medial rectus muscle.

[0006] Furthermore, the biological tissue biomimetic sleeve is made of polyethylene, and a mounting hole is provided at the lower end of the biological tissue biomimetic sleeve.

[0007] Furthermore, the lateral rectus muscle is made of rubber material, the superior rectus muscle is made of rubber material, the inferior rectus muscle is made of rubber material, and the medial rectus muscle is made of rubber material.

[0008] The beneficial effects achieved by the utility model using the above structure are as follows:

[0009] (1) Realistic Simulation: The device provides interns with a highly realistic practice environment by simulating the anatomical structure of the eyeball, including key extraocular muscles such as the medial rectus, inferior rectus, lateral rectus, and superior rectus. This simulation helps interns perform surgeries under conditions close to reality and improve their proficiency in surgical skills.

[0010] (2) Handheld operation: Interns can hold the strabismus hook and operate it on the simulation device. This design not only conforms to the actual operation mode of strabismus surgery, but also can exercise the interns' hand-eye coordination ability and the precision of surgical operation.

[0011] (3) The bionic sleeve is made of polyethylene, which has good transparency and durability, and can clearly display the internal structure while protecting the internal tissue from external damage.

[0012] (4) The medial rectus, lateral rectus, superior rectus, and inferior rectus muscles are all made of rubber material, which is soft, plastic, and durable. It can simulate the texture and elasticity of real extraocular muscles, allowing interns to experience a more realistic surgical experience during the operation. BRIEF DESCRIPTION OF THE DRAWINGS
