Description
Technical field
The invention belongs to medical instruments field, relate to ophthalmic operating set, relate generally to the lip mucosa transplant operation apparatus in a set of lip mucosa eye table reconstruction operations.
Background technology
The maintenance of healthy corneal epithelium depends on corneal limbal epithelial stem cell.When eye is subject to thermal burn, chemical burn, or the impact of immune inflammation factor is as Stevens-Johnson syndrome etc., corneal limbal epithelial stem cell may be caused to lack, thus the symptoms such as the surperficial conjunctival epithelium that goes out to lose face, neovascularization, eye table chronic inflammatory disease and cornea cicatrix muddiness, even can cause perforation of cornea and eyeball forfeiture time serious.And for corneal limbal epithelial stem cell deletion patients, as seen light again, first must rebuild healthy eye surface, on this basis, optical corneal transplantation could success.
The current comparatively ideal therapeutic modality of simple eye corneal limbal epithelial stem cell disappearance is that the corneal limbal tissue of transplanting offside healthy eyes is to suffering from eye with ocular surface reconstruction.But, for cornea of both eyes edge epithelial stem cell deletion patients, international and domesticly at present there is no a kind of desirable eye table reconstruction technique.
Autologous lip mucosa eye table reconstruction operations is the brand new technical carried out in recent years, be applied to the cornea of both eyes limbal stem cell deletion patients that Eye Burns causes, there are some researches show that technique is evident in efficacy, may will become the first-selected operation method for the treatment of cornea of both eyes limbal stem cell disappearance.But the different complexity of this operation, not only will combine the amnion transplantation of eye table, and also need lip mucosa to transplant, and the latter is because of far different with the micrurgy space and orientation of ophthalmology and other training routines, therefore there is no Special surgical instrument at present, operating difficulty is high, and the time is long.
Summary of the invention
The object of this invention is to provide a set of lip mucosa eye table and rebuild apparatus, its structure is simple, easy to operate, fully can expose operating field, is particularly useful for ophthalmology lip mucosa eye table reconstruction operations.
Technical scheme of the present invention is: this cover apparatus is made up of microforceps, microscissors, microscopic needle holder and left hand hemostatic clamp and right hand hemostatic clamp, wherein microforceps comprises tweezer handle, tweezer arm and tweezer head, between tweezer head and tweezer arm, angle α is 45 °-75 °, and tweezer crown end is involutory tooth; Microscissors comprises scissor body, cheek axle, handle and spring leaf, the long 1-1.4 centimetre of scissor body, curved, and is fixed by cheek axle and handle, and between scissor body and handle, angle β is 30 °-45 °; Microscopic needle holder comprises holds needle body, cheek axle, handle and spring leaf, holds the long 1-1.4 centimetre of needle body, curved, and is fixed by cheek axle and handle, and holding angle γ between needle body and handle is 30 °-45 °; Left hand hemostatic clamp comprises finger ring, mentions, tong arm, connecting axle and binding clip, and binding clip is connected by connecting axle with tong arm, and binding clip top is that horizontal semi-circular bends, and radius is about 2-3 centimetre, mentions after buckling, and corresponding binding clip is curved is separated by about 0.5 centimetre.Right hand hemostatic clamp comprises finger ring, mentions, tong arm, connecting axle and binding clip, and binding clip is connected by connecting axle with tong arm, and binding clip top is that horizontal semi-circular bends, and radius is about 2-3 centimetre, mentions after buckling, and corresponding binding clip is curved is separated by about 0.5 centimetre.
The apparatus of the present invention's design can provide the simple operation and suitability that operator is higher, is applicable to patient at its special oral cavity sky operating time, improves procedure efficiency and effect.Popularizing also for this operation method, directly makes more patient's income serve.
Feature of the present invention is: tweezer head, the scissor body of (1) microforceps, microscissors and microscopic needle holder, hold needle body all and body have a certain degree, its length and radian moderate, the lower lip mucosa face in narrow and small inclination is easy to during operation, gripping is separated the lip mucosa tissue of suitable size, do not affect operating field simultaneously, operator more easily can observe the degree of depth of wound, scope and the situation such as hemorrhage, and not easily tears mucosal tissue.(2) hemostatic clamp design is ingenious, not only has hemostasis, a draw of turning up, and easy to operate, easily adjusts range of operation; Apparatus structure is simple.1. the left hand hemostatic clamp that minute surface is involutory and right hand hemostatic clamp are clamped on the left of lower lip and right side respectively, after hemostatic clamp binding clip is involutory, traction hemostasis clamp holder, turn up lower lip, adjustment needs the lower lip mucosa face exposed, and operating field is fully exposed, and binding clip is involutory simultaneously, the lip mucosa tissue of clamping is tightened, there is certain haemostatic effect.After the adjustment of hemostatic clamp gear is fixing, patient is hold by one hand two tong arms and can turns up the lower lip tissue of traction, exposure wound surface.This apparatus solves previously needs both hands tractive, the easy slippage of apparatus, and wound surface exposes not thorough, the series of problems such as the many impact operations of intraoperative hemorrhage, thus operating time is shortened dramatically, wound surface mucosa injury reduces, go out insufficiency of blood, postoperative wound healing is accelerated, and can reduce surgical staff.2. the arc space of about 0.5 cm height is left in the involutory rear centre of the binding clip of left hand hemostatic clamp and right hand hemostatic clamp, and existing certain haemostatic effect can be protected again and have certain thickness lip tissue, avoid tissue ischemia to damage.3. the left hand hemostatic clamp that minute surface is involutory and right hand hemostatic clamp are beneficial to adjustment operating field, and the size shape of clamp ring is suitable for mutually with the size of lip under patient oral cavity again, the not tissue such as lingual frenum, gingiva around easy damaged.(3) adopt combination operating theater instruments of the present invention, can complete lip mucosa transplant operation safely, efficiently, operating time shortens about 30 ~ 45 minutes, and surgical staff reduces by 1 people.(4) the present invention is reasonable in design, and structure is simple, easy to make, is beneficial to and popularizes.
