Embodiment 1

[0017] see Figure 1-Figure 6 , the technical scheme of the present invention is: this set of instruments is made up of micro tweezers 1, micro scissors 2, micro needle holder 3, left-hand hemostatic clip 4 and right-hand hemostatic clip 5, wherein micro tweezers 1 includes tweezers handle 1- 1. Tweezer arm 1-2 and tweezer head 1-3, the angle between tweezer head 1-3 and tweezer arm 1-2 α 45°-75°, the top of the tweezers head 1-3 has teeth; the micro scissors 2 includes a scissors body 2-1, a gill axis 2-2, a handle 2-3 and a spring leaf 2-4, and a scissors body 2- 1 is 1-1.4 centimeters long, is arc-shaped, and is fixed by the gill axis 2-2 and the handle 2-3, and the angle β between the scissors body 2-1 and the handle 2-3 is 30°-45°; Needle device 3 comprises needle-holding body 3-1, cheek shaft 3-2, handle 3-3 and spring leaf 3-4, and needle-holding body 3-1 is long 1-1.4 centimeters, is arc, and passes through the cheek shaft 3- 2 is fixed with the handle 3-3, and the a...

Embodiment 2

[0018] Using the present invention, the left-hand hemostatic clip 4 and the right-hand hemostatic clip 5 clamp the left side and the right side of the lower lip respectively, and adjust the range; the clamp heads are respectively matched (4-5, 5-5), so that the lip mucosal tissue is tightened; Adjust the gears of the jaws (4-2, 5-2) of the forceps arm and fix them; hold the forceps arm (4-3, 5-3) with one hand, pull and evert the lower lip tissue to expose the wound surface. Under the microscope, the surgeon holds the micro-tweezers arm (1-2), the micro-scissors handle (2-3) and the micro-needle holder handle (3-3) respectively, and uses the curved tweezers (1-3 ), the scissors body (2-1) and the needle holder body (3-1) complete operations such as separation, cutting, and suture of the lip mucosal tissue.

Abstract

The invention provides an oral lip mucosa ocular surface reconstruction instrument. The oral lip mucosa ocular surface reconstruction instrument is composed of a pair of microsurgical forceps, a pair of microsurgical scissors, a microsurgical needle holder, a left-hand haemostatic clamp and a right-hand haemostatic clamp. By the adoption of the oral lip mucosa ocular surface reconstruction instrument, oral lip mucosa transplantation surgery can be safely and efficiently completed, the surgical time can be shortened by 30 to 45 minutes, and the number of surgical personnel can be reduced by one; the oral lip mucosa ocular surface reconstruction instrument is suitable for operation in a narrow space, and the surgical field can be easily exposed; the haemostatic clamps have the local pressurizing haemostatic function and the remarkable traction ectropion function, so that the surgical field is fully exposed, operation is convenient, and the mucosa tissue is not injured. The oral lip mucosa ocular surface reconstruction instrument is an oral lip mucosa surgery combined instrument which is reasonable in design, simple in structure, suitable for dedicated spaces and parts, capable of fully exposing the surgical field, particularly suitable for ophthalmology oral lip mucosa ocular surface reconstruction surgery, convenient to operate and manufacture, and capable of being applied and popularized conveniently.

Description

technical field [0001] The invention belongs to the field of medical instruments, and relates to ophthalmic surgical instruments, in particular to a set of surgical instruments for transplantation of the lip and mucous membranes in the reconstruction operation of the ocular surface of the lips and mucous membranes. Background technique [0002] The maintenance of a healthy corneal epithelium is dependent on limbal epithelial stem cells. When the eyes are affected by thermal burns, chemical burns, or immune inflammatory factors such as Stevens-Johnson syndrome, etc., it may lead to the loss of corneal limbal epithelial stem cells, resulting in ocular surface conjunctival epithelialization, neovascularization, chronic ocular surface inflammation and corneal inflammation. Symptoms such as scar turbidity can even cause corneal perforation and eyeball loss in severe cases. And for patients with limbal epithelial stem cell deficiency, if they want to regain their sight, they must...
