Technical Field

[0001] The utility model relates to the technical field of ophthalmic surface surgical instruments, in particular to a micropulse cyclophotocoagulation assistor. Background Art

[0002] Glaucoma is a blinding ophthalmic disease, mainly caused by optic nerve damage due to increased intraocular pressure. Cyclophotocoagulation is one of the common surgical methods for treating glaucoma. Its principle is to coagulate the ciliary body tissue inside the eyeball by photocoagulation, making it degenerate and necrotic, thereby reducing aqueous humor secretion and lowering intraocular pressure to slow down or eliminate persistent eye pain, headache and other symptoms in patients. During micropulse cyclophotocoagulation, it is usually necessary to use a gauge to measure and mark at 3 mm behind the limbus corneae, and then avoid the 3 o'clock and 9 o'clock positions and use a micropulse probe to perform circumferential photocoagulation respectively. Although this method can achieve the marking function in the prior art, there are still problems of inaccurate positioning and range. In addition, during the operation, since the micropulse probe has no auxiliary support and completely depends on the stability of the operator's hand, and in addition, due to the patient's nervousness or fatigue caused by keeping the eyes in the same state for a long time, the eyeball is likely to move unconsciously, which will cause the operation to fail to achieve the expected effect. Summary of the Utility Model

[0007] As a preferred technical solution, the distance from the outer edge of the auxiliary arc plate to the outer wall of the eyeball fixing ring is 4 mm, and the width of the auxiliary arc hole is 1 mm.

[0008] As a preferred technical solution, the auxiliary handle is arranged at the 9 o'clock position of the eyeball fixing ring.

[0009] As a preferred technical solution, the auxiliary arc plate is arranged on one side of the auxiliary handle and is located between the 3 o'clock position and the 9 o'clock position of the eyeball fixing ring, and the radian of the auxiliary arc plate is not greater than 170°.

[0010] As a preferred technical solution, the outer diameter of the eyeball fixing ring is 11.5 mm.

[0011] As a preferred technical solution, the auxiliary handle includes a handle body, and a fixing ring connecting rod is connected to one end of the handle body close to the eyeball fixing ring, and the eyeball fixing ring is connected to the fixing ring connecting rod.

[0020] The present utility model will be further described below in conjunction with the drawings and embodiments. In the following detailed description, only some exemplary embodiments of the present utility model are described by way of illustration. Undoubtedly, those of ordinary skill in the art can recognize that, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the drawings and the description are illustrative in nature and are not used to limit the protection scope of the claims.

[0021] As Figures 1 to 3 shown, the micropulse cyclophotocoagulation assistor is used to assist in fixing the patient's eyeball during the micropulse cyclophotocoagulation process, and at the same time assist in supporting the micropulse probe and guiding and limiting the operation path, so as to improve the accuracy, stability of the surgical operation and shorten the operation time. It specifically includes an auxiliary handle 1, and the handle body 11 is set as a round rod shape and is provided with an anti-slip pattern 2 on the surface to increase the friction between it and the doctor's finger, so as to ensure the smoothness and accuracy of the control.

[0022] The end of the auxiliary handle 1 is fixedly connected with an eyeball fixing ring 3. The bottom end of the eyeball fixing ring 3 is evenly distributed with fixing serrations 4 for assisting in fixing the eyeball, and the end of each fixing serration 4 is set as an arc-shaped end. The eyeball fixing ring 3 is placed at the corneal limbus on the surface of the eyeball, so that the fixing serrations 4 are in contact with the eye surface and gently pressed to fix the eyeball, thereby preventing the patient's eyeball from moving unconsciously due to tension or fatigue caused by keeping the eyeball fixed for a long time during the operation, which helps to ensure the smooth progress of the operation.

[0023] The outer diameter of the eyeball fixation ring 3 is 11.5 mm to ensure that it can be smoothly placed at the corneal limbus on the surface of the eyeball. Multiple eyeball fixation rings 3 with different diameters can be manufactured to improve the flexibility of use. The auxiliary handle 1 of this embodiment includes a handle body 11. One end of the handle body 11 close to the eyeball fixation ring 3 is connected with a fixation ring connecting rod 12. The eyeball fixation ring 3 is connected to the fixation ring connecting rod 12. And the fixation ring connecting rod 12 is set as a bent rod with an arc transition angle α, and the range of the arc transition angle α is 110-160°, so that a certain angle is formed between the handle body 11 and the eyeball fixation ring 3, thus forming a spatial avoidance and minimizing the occlusion of the surgical field. The handle body 11 and the fixation ring connecting rod 12 are detachably connected, such as threaded connection, snap connection, etc., so that the two can be freely assembled to facilitate the selection of the eyeball fixation ring 3 with different diameters and reduce the configuration of general components such as the handle body 11. For the convenience of replacing and using the eyeball fixation rings 3 of different sizes, the assembly method between the eyeball fixation ring 3 and the fixation ring connecting rod 12 can also be set as detachable.

[0024] A probe auxiliary device for cooperating with a micropulse probe is fixedly connected to the outer surface of the eyeball fixation ring 3. The probe auxiliary device is arranged on the side of the auxiliary handle 1, and the auxiliary arc plate 5 is arranged on one side of the auxiliary handle 1, as Figure 2 shown. The probe auxiliary device can be arranged on the upper side or the lower side of the auxiliary handle 1 to reduce the maximum width of this embodiment extending into the ocular surface part, so as to ensure that the eyeball fixation can be smoothly implemented. For convenient use, this embodiment can be set to have two types of the probe auxiliary device on the upper side or the lower side of the auxiliary handle 1 for use at different positions on the ocular surface during the operation.

[0025] Specifically, the probe auxiliary device includes an auxiliary arc plate 5 fixedly extending outward on the outer surface of the eyeball fixation ring 3. An auxiliary arc hole 6 penetrates through the auxiliary arc plate 5, and the auxiliary arc plate 5 is set as a curved surface gradually changing outward from the eyeball fixation ring 3 to adapt to the change of the curvature of the eyeball surface. During use, the micropulse probe passes through the auxiliary arc hole 6 and enters the ocular surface. By contacting the pore wall of the auxiliary arc hole 6, the auxiliary arc plate 5 forms a support for the micropulse probe to improve the accuracy and stability of the manipulation of the micropulse probe and reduce its dependence on the stability of the doctor's hand. The top surface of the auxiliary arc plate 5 can be set lower than the top surface of the eyeball fixation ring 3, so that the auxiliary arc plate 5 is as close as possible to the ocular surface tissue to ensure that the micropulse probe can contact the surgical site during the operation.

[0026] Among them, the distance from the outer edge of the auxiliary arc plate 5 to the outer wall of the eyeball fixing ring 3 is 4 mm, and the width of the auxiliary arc hole 6 is 1 mm. The distance from the center of the auxiliary arc hole 6 to the outer wall of the eyeball fixing ring 3 is about 3 mm, which can not only meet the operation of the micropulse probe but also cooperate with the eye smoothly. During the micropulse cyclophotocoagulation process, it is necessary to avoid the 3:00 and 9:00 meridian areas to prevent damage to the long posterior ciliary artery and nerve. Based on this, in this embodiment, the auxiliary handle 1 is arranged at the 9 o'clock position of the eyeball fixing ring 3 to form a mark at the 9 o'clock position of the eyeball fixing ring 3, and the opposite side thereof is the 3 o'clock position of the eyeball fixing ring 3, so that there is no need to make a special position mark for the meridian area. The auxiliary arc plate 5 is located between the 3 o'clock position and the 9 o'clock position of the eyeball fixing ring 3, and the radian of the auxiliary arc plate 5 is not greater than 170°. Since the auxiliary arc plate 5 limits and guides the path of the micropulse probe, it is ensured that during the operation of the micropulse probe, the 3:00 and 9:00 meridian areas can be naturally and smoothly avoided. A through hole can be provided in the auxiliary arc plate 5 between the auxiliary arc hole 6 and the outer wall of the eyeball fixing ring 3, so that most of the auxiliary arc plate 5 is in a hollow state, which can reduce the weight of the whole auxiliary device, be more suitable for use on the eye surface, and at the same time help to ensure the surgical field of view during the operation, facilitate observation, and enable the operation to be carried out smoothly and quickly.

[0027] The description of the present invention has been given for purposes of illustration and description, and is not intended to be exhaustive or to limit the invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments were chosen and described in order to best explain the principles of the invention and its practical application, and to enable others of ordinary skill in the art to understand the invention and design various embodiments with various modifications suitable for the particular use.
