Description

A set of oral and mucous membrane ocular surface reconstruction instruments

technical field

The utility model belongs to the field of medical instruments and relates to an ophthalmic surgical instrument, in particular to a set of surgical instruments for transplantation of the lip and mucous membrane in the eye surface reconstruction operation of the lip and mucous membrane.

Background technique

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 first rebuild a healthy ocular surface. On this basis, optical corneal transplantation can be successful.

At present, the ideal treatment for the lack of limbal epithelial stem cells in one eye is to transplant the limbal tissue from the contralateral healthy eye to the affected eye to reconstruct the ocular surface. However, for patients with limbal epithelial stem cell deficiency in both eyes, there is no ideal ocular surface reconstruction technology at home and abroad.

Autologous lip and mucous membrane ocular surface reconstruction surgery is a brand-new technique developed in recent years. It is applied to patients with bilateral corneal limbal stem cell deficiency caused by ocular burns. Studies have shown that this technique has a significant effect and may become a treatment for bilateral corneal limbal stem cells. Missing preferred surgical approach. However, this operation is very complicated, not only combined ocular surface amniotic membrane transplantation, but also lip mucosal transplantation, and the latter is very different from the conventional microscopic operation space and orientation in ophthalmology and other specialties, so there are no special surgical instruments at present, and the operation is very difficult ,long time.

Contents of the invention

The purpose of the utility model is to provide a set of lip mucous membrane and ocular surface reconstruction apparatus, which is simple in structure, easy to operate, can fully expose the operation field, and is suitable for ophthalmic lip mucous membrane and ocular surface reconstruction surgery.

The technical scheme of the utility model is: the set of instruments is composed of micro tweezers, micro scissors, micro needle holder, left-hand hemostatic clip and right-hand hemostatic clip. The angle α between the head and the tweezers arm is 45°-75°, and the top of the tweezers has teeth; the micro scissors include the scissors body, the cheek shaft, the handle and the spring leaf. The length of the scissors body is 1-1.4 cm, which is curved , and fixed by the gill axis and the handle, the angle β between the scissors body and the handle is 30°-45°; the micro needle holder includes the needle body, the gill axis, the handle and the spring leaf, and the length of the needle body is 1-1.4 Centimeter, arc-shaped, and fixed by the gill axis and the handle, the angle γ between the needle holder and the handle is 30°-45°; the left-hand hemostatic clip includes a ring, hanging teeth, forceps arm, connecting shaft and forceps head, forceps head It is connected with the pliers arm through a connecting shaft, and the top of the pliers head is curved in a horizontal semicircle with a radius of about 2-3 cm. After the hanging teeth are fastened, the corresponding pliers heads are curved and separated by about 0.5 cm. The right-hand hemostatic clip includes a ring, hanging teeth, forceps arm, connecting shaft and pliers head. The pliers head and pliers arm are connected by a connecting shaft. The top of the pliers head is curved in a horizontal semicircle with a radius of about 2-3 cm. The tips of the forceps are curved approximately 0.5 cm apart.

The instrument designed by the utility model can provide the operator with higher convenience and suitability for operation, and is suitable for the operator to collect materials from the mucous membrane under the special oral space and orientation, fully expose the operation field, and protect the mucous membrane tissue of the lips as much as possible. Reduce difficulty, shorten operation time, improve operation efficiency and effect. It also serves for the promotion and popularization of this surgical method, directly benefiting more patients.

The utility model is characterized in that: (1) the tweezers head, scissors body and needle holder of micro tweezers, micro scissors and micro needle holder all form a certain angle with the body, and their length and radian are moderate, so that they It is easy to pick and separate the lip mucosal tissue of appropriate size on the narrow and inclined lower lip mucosal surface without affecting the surgical field. The operator can more easily observe the depth, scope and bleeding of the wound, and it is not easy to tear the mucosal tissue . (2) The hemostatic clip is ingeniously designed, not only has the functions of hemostasis and valgus traction, but also is easy to operate and easy to adjust the operation range; the device structure is simple. ①The left-hand hemostatic clip and the right-hand hemostatic clip that are mirror-fitted respectively clamp the left and right sides of the lower lip. After the hemostatic clip heads are closed, pull the hemostatic clip handle, turn the lower lip eversion, and adjust the mucosal surface of the lower lip that needs to be exposed , so that the operation field is fully exposed, and at the same time, the closure of the forceps makes the clamped lip mucosa tissue tight, which has a certain hemostatic effect. After the position of the hemostatic clip is adjusted and fixed, the surgeon can hold the two arms of the forceps with one hand and pull the lower lip tissue outwards to expose the wound. This device solves a series of problems in the past, such as pulling with both hands, easy slippage of the device, incomplete exposure of the wound surface, and a lot of bleeding during the operation that affects the operation, so that the operation time is greatly shortened, the damage to the wound mucosa is reduced, the bleeding is less, and the wound heals after the operation. faster, and can also reduce the operating staff. ② After the clamp heads of the left-hand hemostatic clip and the right-hand hemostatic clip are combined, there is an arc-shaped space with a height of about 0.5 cm in the middle, which not only has a certain hemostatic effect, but also can protect the lip tissue with a certain thickness and avoid tissue ischemia damage. ③The mirror-fitted left-hand hemostatic clip and right-hand hemostatic clip are beneficial to adjust the surgical field, and the size and shape of the clip rings are suitable for the size of the lower lip of the patient's mouth, so that it is not easy to damage the surrounding frenulum, gums and other tissues. (3) Using the combined surgical instrument of the present utility model, the lip and mucous membrane transplantation can be completed safely and efficiently, the operation time is shortened by about 30-45 minutes, and the number of surgical personnel is reduced by 1. (4) The utility model is reasonable in design, simple in structure, convenient to manufacture, and beneficial to promotion and popularization.
