Hole Locator for Retinal Detachment Repair Surgery

Abstract

The invention discloses a retinal hole positioner used for searching for a retinal hole and positioning the retinal hole accurately. The retinal hole positioner used for a retinal detachment repair operation comprises a device with a pressing head, wherein the device can be put into an eye socket to press a sclera. The device is a bar piece which is in a thin and long shape, wherein the middle portion of the device is a main handle suitable for being held by one hand. A left probing bar and a right probing bar are respectively arranged at the left end of the main handle and the right end of the main handle. The outwards protruded pressing head is arranged at the end of the left probing bar. An outwards protruded positioning head in a barrel shape is arranged at the end of the right probing rod. The outer end face of the barrel is an outwards protruded circular sliding surface. The axial length of the barrel is 1.5 mm to 2.5 mm, the external diameter of the barrel is 1.5 mm to 2.0 mm and the internal diameter of the barrel is 1.4 to 1.9 mm. According to the retinal hole positioner used for the retinal detachment repair operation, by adopting the positioning head in the barrel shape, an operation doctor can press down on the sclera and leave a clear differentiable and retainable circular mark which never disappears with the positioning head in the barrel shape after checking and searching for the retinal detachment hole and ensuring the occurring position of the retinal detachment hole with the pressing head, so that the doctor can ensure the accuracy of the operation when performing an operation.

Description

technical field [0001] The invention relates to an appliance for medical operation, in particular to an appliance for locating a hole in repairing retinal detachment operation. Background technique [0002] The retina is a layer of translucent membrane in the eye. It is the first stop for the transmission of nerve information formed by vision. It has a very fine network structure and rich metabolic and physiological functions. The retina is divided into ten layers, the inner nine layers are the neuroepithelium, the outer layer is called the pigment epithelium, and there is a certain potential gap between the two layers. When some kind of liquid enters the gap or the neuroepithelium is pulled by the vitreous, the neuroepithelium and pigment epithelium of the retina are easily separated, that is, retinal detachment occurs. [0003] Retinal detachment (RRD) is a serious eye disease, if not repaired in time, the patient will be blind. Since Gonin (1920) successfully used therm...

Problems solved by technology

[0006] 1) Top pressure marks are easy to disappear

[0007] The pressure end of the above-mentioned tweezers, electrocoagulation head or condensation head is a smooth protrusion. After pressing the corresponding sclera with it, during the operation, the doctor judges according to the pressure marks left on the sclera by using the pressure search method in advance. The location of the hole, usually, it takes a period of time from the pressure to find the hole, to pull the extraocular muscles to turn the eyeball, and then to prepare for the operation. At this time, the pressure marks left by the pressure end on the sclera Will gradually disappear as the sclera regains elasticity and become illegible

[0008] 2) It is easy to cause errors in judging the position of the hole

[0009] Use tweezers, electrocoagulation head or condensation head to locate. Due to the large pressure area on the sclera, the traces are often not obvious. , some doctors may misjudge the location of the hole due to differences in the recognition of surgeons
