Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an intraocular retinal proliferative membrane separator. Background Art

[0002] During vitreoretinal surgery, separating the adherent proliferative membrane is a challenging task and a crucial and challenging issue in the treatment of vitreoretinal diseases. If this separation is not performed properly, a retinal tear can form. Ruptured retinal blood vessels and bleeding can lead to serious complications, negatively impacting imaging and surgical outcomes, as well as postoperative vision.

[0003] The management of proliferative membranes varies depending on the disease. Common methods for peeling include forceps peeling, scissor segmentation, and scissor separation. If the proliferative membrane is loosely adherent and does not cause iatrogenic retinal tears or bleeding during peeling, forceps peeling and other methods are the best approach and can effectively treat the condition. However, in some cases, the proliferative membrane is often tightly adhered, making scissor segmentation and / or separation more prone to complications.

[0004] When using forceps for peeling, the forceps may pinch and pull the proliferative membrane and the retina together, or the proliferative membrane may be heavily adhered, and the retina may be pulled and lifted when the proliferative membrane is pinched. This can easily tear the retina and form an iatrogenic tear, or tear the retinal blood vessels or the new blood vessels on the proliferative membrane, causing heavy bleeding, affecting subsequent operations, resulting in unsatisfactory postoperative surgical results, poor patient satisfaction, and even medical disputes. Even if scissors are used to cut, there must be a gap for the scissors to penetrate deeply, regardless of whether the scissors are used vertically or horizontally. However, when using scissors or other methods to create this gap, retinal tears or bleeding may often form due to sharp operation, or the proliferative membrane and retina are adhered and cannot be identified, leaving no gap for the scissors to work.

[0005] Using a wave cutting head for shearing, similar to using scissors, can also cause complications. Furthermore, the wave cutting head is thick, and some proliferative membranes cannot be penetrated for operation. During operation, the wave cutting head exerts a certain amount of negative pressure, which can also stretch the retina. If the negative pressure needs to be turned off, an assistant will be required, which will affect the operation time and progress.

[0006] In view of this, an intraocular retinal proliferative membrane separator is proposed to avoid the occurrence of complications caused by the above-mentioned operation. Utility Model Content

[0007] The purpose of the utility model is to provide an intraocular retinal proliferative membrane separator to solve the above-mentioned technical problems.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an intraocular retinal proliferative membrane separator, comprising a handle, a storage tube fixedly installed at the front end of the handle, a slide groove running through the surface of the handle, an L-shaped push block slidably sleeved on the inner wall of the slide groove, the horizontal end portion of the L-shaped push block fits on the outer surface of the handle, the vertical end portion of the L-shaped push block is fixedly installed with a slide plate, the slide plate piston is sleeved on the inner wall of the handle, a push rod is fixedly installed on the surface of the slide plate, the push rod is slidably sleeved inside the storage tube, and a separator is fixedly provided on the end of the push rod away from the slide plate.

[0009] Preferably, a fixed sleeve at one end of the inner wall of the storage tube close to the slide is provided with a head, a fixed sleeve in the middle section of the inner wall of the storage tube is provided with an inner lining tube, the push rod surface passes through and slides through the head and the inner lining tube surface, and the separator is composed of three elastic spiral steel wires.

[0011] Compared with related technologies, the intraocular retinal proliferative membrane separator provided by the present invention has the following beneficial effects:

[0012] The utility model provides an intraocular retinal proliferative membrane separator, which pushes the L-shaped push block to make its vertical end slide on the inner wall of the slide groove, thereby driving the slide plate to slide inside the handle, and then driving the push rod to slide inside the storage tube, so that the separator located at the end of the push rod extends out of the end of the storage tube, and the separator supports and separates the proliferative membrane, releases the adhesion between the retina and the proliferative membrane, and provides a suitable gap for tools such as a wave cutting head or scissors to operate, while not causing trauma to the retina, effectively improving practicality.

[0013] The utility model provides an intraocular retinal proliferative membrane separator. When the separator is used to separate the retina, an optical fiber is inserted into a receiving tube through an optical fiber introduction tube, and then light from the optical fiber head end is projected to the front end of the receiving tube through a light-transmitting hole and released out, thereby illuminating the tissue near the separator, which is more conducive to the operator's operation and does not require the use of additional lighting means, making it more convenient to use.

[0019] See also Figures 1-4 The utility model provides a technical solution, including a handle 1, a storage tube 13 is fixedly installed at the front end of the handle 1, a slide groove 11 is opened through the surface of the handle 1, an L-shaped push block 12 is slidably sleeved on the inner wall of the slide groove 11, the horizontal end of the L-shaped push block 12 is fitted on the outer surface of the handle 1, a slide plate 15 is fixedly installed on the vertical end of the L-shaped push block 12, the slide plate 15 piston is sleeved on the inner wall of the handle 1, a push rod 14 is fixedly installed on the surface of the slide plate 15, the push rod 14 is slidably sleeved inside the storage tube 13, and a separator 17 is fixed on the end of the push rod 14 away from the slide plate 15;

[0020] By pushing the L-shaped push block 12, the vertical end portion thereof slides on the inner wall of the slide groove 11, thereby driving the slide plate 15 to slide inside the handle 1, and then driving the push rod 14 to slide inside the storage tube 13, so that the separator 17 at the end of the push rod 14 extends out of the end of the storage tube 13, and the separator 17 supports and separates the proliferative membrane, thereby releasing the adhesion between the retina and the proliferative membrane, providing a suitable gap for tools such as a wave cutting head or scissors to operate, and at the same time will not cause trauma to the retina, thereby effectively improving practicality.

[0021] The inner wall of the receiving tube 13 is fixedly sleeved with a head 2 at one end near the slide 15, and the middle section of the inner wall of the receiving tube 13 is fixedly sleeved with an inner liner 18. The surface of the push rod 14 passes through and slides on the surface of the head 2 and the inner liner 18. The separator 17 is composed of three elastic spiral steel wires.

[0022] The head 2 and the inner lining tube 18 support the push rod 14. When the push rod 14 slides back and forth on the inner wall of the storage tube 13, it remains stable and will not shake, thereby making the extension and insertion of the separator 17 smoother. The separator 17 is made of an alloy material including but not limited to steel wire. At the same time, the spiral structure design of the separator 17 allows the separator 17 to gradually diffuse outward due to elasticity after extending out 13, and can have good support. It can scrape on the retina or proliferative membrane, and can easily and quickly scrape up a flap, which is beneficial for subsequent operations. The elasticity is appropriate, neither hard nor soft, and will not cause trauma to the retina.

A light-transmitting hole 19 is formed through the surface of the inner lining tube 18. The optical fiber introduction tube 16 is connected to the inner wall of the storage tube 13 through the light-transmitting hole 19.

[0024] When the separator 17 is used to separate the retina, the optical fiber is inserted into the storage tube 13 through the optical fiber introduction tube 16, and then the light from the optical fiber head is projected to the front end of the storage tube 13 through the light-transmitting hole 19 and released out, thereby illuminating the tissue near the separator 17, which is more conducive to the operator's operation. At the same time, there is no need to use additional lighting means, and it is more convenient to use.
