Problems solved by technology

This operation is inefficient, the effect is not good, and more importantly, it is easy to damage the retina
Because the retina can be reattached only by repeated pushing and attracting, the chances of multiple injuries will inevitably increase; and since the retinal hook or flute-shaped needle is a metal device, it is difficult to completely avoid damage to the retina by the hard surface of the working surface. Neuroepithelial tissue causing microtrauma or even full-thickness retinal tear

Embodiment 1

[0029] The structure of the retinal applanator is as follows: figure 1 As shown, it consists of a working head 1, a rod body 2 and a handle 3. The rod body 2 is a metal rod made of stainless steel with a diameter of 0.4mm and a length of 40mm. The working head 1 and the rod body form an angle of 120 degrees. Its angle can be fine-tuned with blood vessel forceps, and the base body 11 of this working head is the continuous body with the same diameter of rod body 2 (such as figure 2 As shown), its length is 2mm, and a very thin silicone sheet 13 is inlaid on the downward side of the substrate 11 as a soft touch working element. Its shape is similar to a brush, and the thickness of the silicone sheet 13 is 0.1mm. The length protruding from the substrate is 0.3mm (such as image 3 , 4 shown). The total length of the retina applanator is about 110mm.

[0030] When using this retina applanator, adjust the angle of the working head with vascular forceps according to different mas...

Embodiment 2

[0032] The structure of the retinal applanator is shown in Figure 5. It consists of a working head 1, a rod body 2 and a handle 3. The rod body 2 is a metal rod made of stainless steel with a diameter of 0.8 mm and a length of 30 mm. The working head 1 It forms an angle of 120 degrees with the rod body, and the angle can be adjusted by vascular forceps during use. The soft touch working element of the working head is a silicone tube 12 set on the base body, and the thickness of the tube wall is 0.2mm (such as Figure 7 shown). The base of the working head can be the core portion 11 of the reduced diameter extending from the front end of the rod body, with a diameter of about 0.4mm (such as Figure 8 shown), after the silicone tube 12 is inserted into the matrix, the outer diameter of the entire working head is equal to the outer diameter of the rod body (such as Figure 6 shown). The total length of the retina applanator is about 130mm.

Embodiment 3

[0034] The structure of the retinal applanator is shown in Figure 9. It consists of a working head 1, a rod body 2 and a handle 3. Its structure is basically the same as that of Embodiment 2. The difference lies in the silicone rubber used as the soft touch working element of the working head. Pipe 12 is only enclosed within a section of working head front (as Figure 10 shown). The silicone tube 12 of the working head and the substrate 11 are as Figure 11 , 12 shown.

Abstract

Disclosed is a retina prostration apparatus which is a medical equipment for detaching, flattening and recovering retina during a vitreum and retina detaching surgery, wherein the device comprises an elongated pole member and an operation head on the front end of the pole member, the operation head includes a base member and a soft mass touch working element mounted on the base member. The device can be used for the smoothing operation for massaging and touching the retina in surgery.

Description

technical field [0001] The present invention relates to a medical device for flattening the membrane after it has been peeled off and restoring the retina in modern vitreoretinal stripping surgery. Background technique [0002] Thorough membrane stripping in modern vitreoretinal surgery is the key to successful surgery. With the maturity of microscopic techniques and the deepening understanding of surgery, how to better flatten and restore the retina after membrane stripping, especially stretch the key parts such as the macula , is directly related to the effect of the whole operation. [0003] At present, there is no special instrument for this operation, and most operators often use the existing retinal hook or flute-shaped needle tip to drag repeatedly on the retinal surface to achieve the above-mentioned purpose. This kind of operation is inefficient, the effect is not good, and more importantly, it is easy to damage the retina. Because the retina can be reattached onl...
