Abstract

The utility model relates to a separation positioner used for resection of pterygium, which comprises a base, the base is in a straight cylinder shape, anti-skidding areas are arranged on the upper portion and the lower portion of the base, an end cover is arranged at one end of the base and is in threaded connection with the base, screwing threads are arranged at one end of the base and one end of the end cover, and the other end of the base and the other end of the end cover are in threaded connection with the end cover. A separation marking ruler is clamped at the screwing thread, and the separation marking ruler can be fixed with the base through screwing of the end cover. By adopting the new separation marking ruler, the size of the pterygium and the size mark of subsequent transplantation of the to-be-transplanted valve can be intuitively measured, control by experience of an operator is not needed, meanwhile, the transplanted valve which is marked can be more regular after being cut off through the mark, and the transplanted valve is more attractive when transplanted to the pterygium removal position, so that the operation is more convenient, and the operation is more convenient. And the suturing work of the follow-up operation is also facilitated.

Description

Technical Field

[0001] The utility model belongs to the field of pterygium excision, and in particular relates to a separation positioner used for pterygium excision. Background Art

[0002] Pterygium resection is used for the surgical treatment of pterygium. Pterygium is a chronic inflammatory lesion caused by chronic irritation of the conjunctiva. When pterygium progressively covers part or all of the pupil, affecting vision and eye movement, and affecting appearance, surgical treatment can be performed.

[0003] The existing pterygium resection surgery requires the transplantation of a graft flap at the resection site, but the existing tools lack a comparative measurement tool for the size area of ​​pterygium and graft flap. The size control of the graft flap is based on the surgeon's experience, which is not enough for the rigor of the operation. Therefore, a separation locator that can locate the size is needed. Utility Model Content

[0004] The above-mentioned purpose of the utility model is achieved through the following technical solutions:

[0005] A separation positioner for pterygium excision includes specific surgical steps for pterygium excision:

[0006] S1: The patient lies in the supine position, and the surrounding skin is routinely disinfected with iodine, and sterile surgical towels and surgical hole towels are laid, and ophthalmic surgical films are applied, and a lid opener is placed;

[0007] S2: topical anesthesia with proparacaine hydrochloride eye drops, local infiltration anesthesia of the pterygium head and body with 2% lidocaine, and fixation of the eyeball with traction using 6-0 absorbable sutures;

[0008] S3: Plan the locator according to the size of the pterygium and evenly apply it with a marking pen, mark the size of the pterygium removal, remove and separate the pterygium head under a microscope, reach the corneal epithelium, separate toward the pterygium body, reach the pterygium root at the inner canthus, stop bleeding with bipolar electrocoagulation, remove the pterygium with corneal scissors, and expose an area of ​​about 6*8mm for the reserved transplant flap transplantation;

[0009] S4: Clean the residual pterygium tissue in the exposed area, mark the conjunctival locator above the temporal part with corneal scissors, and separate a conjunctival flap of about 7*9mm to the corneal sclera edge;

[0010] S5: Transfer to the exposed area of ​​pterygium, fix the four corners of the stem cell transplant flap and the conjunctiva of the exposed area of ​​pterygium with 10-0 sutures, flatten the transplant flap, fix the transplant flap surface with 10-0 sutures along the top, bottom and outside of the transplant flap, check that the transplant flap has no displacement, is flat, and is fixed with sutures;

[0011] S6: flush the remaining blood in the eye and cover the cornea with a hydrophilic contact lens;

[0012] S7: After applying tobramycin demi eye ointment and bandaging the operated eye with sterile gauze, the patient returned to the ward.

[0013] Preferably, the separation locator includes a base, the base is in the shape of a straight cylinder, and anti-slip areas are provided on the upper and lower parts of the base. An end cap is provided at one end of the base, and the end cap is threadedly connected to the base. The base and one end of the end cap are provided with tightening threads, and a separation marking ruler is clamped at the tightening threads. The separation marking ruler can be fixed to the base by screwing the end cap.

[0014] Preferably, the separate marking ruler includes a connecting curved rod, one end of which is connected to the tightening thread, and the other end of which is connected to a U-shaped marking pen, both ends of which are filled with medical marking ink, and the U-shaped marking pen can be replaced with multiple sizes, with a length ranging from 4-8 mm and a width ranging from 6-10 mm.

[0015] Preferably, the base is made of stainless steel.

[0016] In summary, the present invention includes at least one of the following beneficial technical effects:

[0017] By adopting the new separation marking ruler, the size of the pterygium and the size mark of the subsequent transplant flap can be measured intuitively, and the surgeon's experience is no longer needed to control it. At the same time, the marked transplant flap can be more regular when cut, and it can be more beautiful when transplanted to the pterygium removal site, which is also more conducive to the suturing work of subsequent surgery.
