Problems solved by technology

However, due to the anatomical curvature and remoteness, the bulkiness of existing instruments makes it impossible for a probe inserted from an extremity to reach the central retinal artery of the eye
[0005] There are mature technologies in contemporary ophthalmology. The optic nerve and fundus are exposed through surgical methods. Therefore, it is possible to unblock the central retinal artery blockage from the local part of the eye. However, there is no corresponding instrument for surgical operation.

Embodiment 1

[0021] Example 1 Making a Central Retinal Artery Probe with an Integrated Structure

[0022] Select medical metal materials such as stainless steel, titanium-nickel alloy, etc., and use casting, forging or cutting methods to make a connected central retinal artery probe, such as figure 1 As shown, it includes a probe piece 3, a support rod 2 and a handle 1. Among them, the probe part 3 is cylindrical or conical with a thick top and a thin bottom, with a diameter of 0.1-0.2 mm and a length of 5-7 mm. The front end is polished into a hemispherical or arc-shaped shape; the support rod 2 is cylindrical or flat. Shape, 1.2~1.8mm in diameter, 3~4cm in length; handle 1 is cylindrical, oblate or any shape suitable for holding.

Embodiment 2

[0023] Example 2 Making a central retinal artery probe with a two-body structure

[0024] Such as figure 1 As shown, the probe part 3 and the support rod 2 of the central retinal artery probe of the present invention are made into one body, and the handle 1 is integrated into one body. Use the 1ml syringe needle as the handle 1. The tail end of the support rod 2 is cap-shaped, its size and shape are the same as the tail end of the No. 7 needle for injection, and can be sleeved on the syringe needle tube.

Embodiment 3

[0025] Example 3 Making a retractable central retinal artery probe

[0026] Such as Figure 2A and Figure 2B As shown, the central retinal artery probe of the present invention has a three-body or two-body structure. Wherein, the probe part 3 is one body, and the support rod 2 and the handle 1 are one body or two bodies. The probe part 3 is cylindrical or conical, and the support rod 2 and the handle 1 are hollow tubes. The power of the probe part 3 expanding and contracting in the lumen of the support rod 2 can have two structural modes: one way is to install a guide wire 4 and a spring in the lumen, and set a button 5 on the handle 1 . Both the front end of the guide wire 4 and the spring are connected with the probe piece 3 , and the rear end of the guide wire 4 is connected with the button 5 on the handle 1 . The guide wire 4 pulls the probe piece 3 to retract, and the spring pushes the probe piece 3 to stretch out; another way to make the probe piece 3 stretch is to ...

Abstract

The invention discloses a probe for central artery of retina for dredging central artery embolism of retina, which comprises a probe body, a supporting rod and a handle, and can be integrated into an all-in-one structure, a dyad structure or a triad structure. The probe can be designed as a retractable structure in the supporting rod, which can have attraction function at the same time.

Description

technical field [0001] The invention belongs to medical instruments for operation, in particular to an instrument used in ophthalmology for fundus surgery. Background technique [0002] The pathogenesis of central retinal artery occlusion is that an embolus forms an embolism in the central retinal artery, blocking blood flow, causing tissue degeneration and necrosis in the blood supply area such as the retina, and can immediately cause blindness. It is difficult to restore vision if the course of disease exceeds 3 days. Central retinal artery occlusion is an ophthalmic emergency, and there is currently no recognized effective drug or surgical treatment. Theoretically, the key to its treatment is to quickly dislodge the embolus and restore blood circulation. [0003] Probes have been used in surgical operations for a long time, and are mainly used to explore the internal conditions of lumens and sinuses. Surgical probes are several millimeters thick and more than 10 centim...
