Description

Technical Field

[0001] The utility model belongs to the technical field of medical surgery, and particularly relates to a surgical device for conjunctival sac stenosis repair, especially a spacer device for preventing adhesion of the conjunctival sac. Background Art

[0002] The conjunctiva is a thin, semi-transparent mucous membrane that is soft, smooth, and elastic. It covers the back of the eyelids (palpebral conjunctiva, firmly adhered to the tarsal plate and cannot be pushed. Under normal circumstances, small blood vessels can be seen running and some meibomian gland ducts can be seen through), the surface of the anterior part of the sclera of the eyeball (bulbar conjunctiva, covering the surface of the anterior part of the sclera of the eyeball, ending at the corneal limbus, which is the thinnest and most transparent part of the conjunctiva, can be pushed, and there is a loose connection between the bulbar conjunctiva and the sclera by the fascia bulbi. It fuses with the fascia bulbi and the sclera within 3 mm near the corneal limbus), and the reflected part from the eyelid part to the bulbar part (forniceal conjunctiva, the conjunctival tissue is loose and has many folds to facilitate eye movement. The superior fornix has the attachment of the levator palpebrae superioris fibers, and the inferior fornix has the fibers of the inferior rectus muscle sheath incorporated). These three parts of the conjunctiva form a sac-like space with the palpebral fissure as the opening, called the conjunctival sac.

[0003] Conjunctival sac stenosis refers to the situation where after the eyeball is removed due to trauma, inflammation, or other eye diseases, the conjunctival sac shrinks or even contracts, causing the conjunctival sac to become shallower and smaller, resulting in the inability to insert an artificial eye (false eye) of an appropriate size and shape, or the spontaneous prolapse of the artificial eye piece, causing appearance defects and seriously affecting the appearance and self-confidence. In response to this situation, free grafting of the lower lip or (and) buccal mucosa is required to perform conjunctival sac plasty for these patients to deepen the fornix. However, to ensure the long-term and stable deepening effect, the deepened forniceal conjunctiva needs to be temporarily fixed to the periosteum of the lower orbital margin. The specific operation is to insert a double-needle suture from the corresponding conjunctiva in the lower fornix, pass through the periosteum of the lower orbital margin and then exit from the skin surface, and tie it on the skin surface. However, clinically, directly fixing and suturing with sutures often causes the conjunctiva to be cut by the sutures and rupture, weakening the fixation effect. Summary of the Invention

[0004] To solve the above technical problems, it can be considered to solve the problem of being cut by the suture through padding. Currently, there is no ready-made fixing material in clinical practice that can pad between the suture and the conjunctiva and between the suture and the skin. Therefore, the utility model provides a spacer device for preventing adhesion of the conjunctival sac. By padding between the conjunctiva, the suture, and the skin, it is used to reduce iatrogenic injury and avoid adhesion between the two layers of the conjunctiva (the two surfaces of the conjunctival sac) during tissue repair.

[0005] The specific structure is as follows:

[0006] A surgical device for the repair of conjunctival sac stenosis, the device comprising a spatula needle and a suture, the spatula needle being a double-headed suture needle, and the needle tails of the two suture needles being connected by a suture; further comprising an anti-adhesion component, the anti-adhesion component including a lower fornix barrier component and a skin surface barrier;

[0007] The lower fornix barrier is rod-shaped, with a wire hole running through it along the long axis direction, and side holes are provided at both ends; the suture passes through the wire hole and exits through the side hole;

[0008] The skin surface barrier is a gasket provided with two needle exit holes, and the needle exit holes are provided at both ends of the gasket (3) along the thickness direction of the gasket.

[0009] Further, the lower fornix barrier is a rod-shaped body with a diameter of 3 mm and a length of 8 mm.

[0010] Further, the diameter of the wire hole is 1.5 mm.

[0011] Further, there are two side holes, and the two side holes are arranged in a straight line on any side of the lower fornix barrier.

[0012] Further, the distance between the two side holes is 4 mm.

[0013] Further, the gasket is 8 mm long, 4 mm wide, and 2 mm thick.

[0014] Further, the needle exit hole includes a needle inlet and a needle outlet, and is an "eight"-shaped inclined hole with the needle outlet facing inwards.

[0015] Further, the hole distance between the needle inlets of the two needle exit holes is 4 mm.

[0016] Further, the needle exit holes are provided 2 mm from both ends.

[0017] Introduction to the working principle of the present utility model:

[0018] 1) Insert one needle of the non-absorbable thread of the double-headed stainless steel spatula needle 1 (2-0 or 1-0) into the first side hole 421 of the silicone rod, and then pass through and exit from the first side hole 421;

[0019] 2) Insert the two needles into the lower fornix palpebral conjunctiva surface, pass through the suborbital margin periosteum and exit from the skin surface, and place the lower fornix barrier 4 at the bottom of the lower fornix (between the bulbar conjunctiva and the palpebral conjunctiva);

[0020] 3) Then pass the two needles through the needle exit holes 51 of the 8 mm long skin surface barrier 5 to obtain the silicone sheet;

[0021] 4) Tie a knot outside the silicone sheet with the suture 2;

[0022] 5) According to the condition of the conjunctival sac, place 2-3 groups of the above devices to complete the operation.

[0023] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0024] (1) While the soft silicone protects the conjunctiva and skin by elastic pad application, it is not easily cut by the suture, which can ensure the structural stability during fixation and make the fixation effect more predictable.

[0025] (2) The silicone rod is placed at the bottom of the lower fornix. While maintaining the depth of the fornix, it can also keep the width of the lower fornix, especially avoiding the adhesion of the conjunctiva on both sides of the silicone rod (two surfaces of the conjunctival sac) during the tissue repair process.
