Description
Technical Field
The invention relates to the technical field of ophthalmic medical equipment, in particular to an intraoperative eyeball fixer which is used for fixing an eyeball in the operation process of ophthalmic surgery and avoiding operation difficulty and operation time extension caused by rotation of the eyeball in the surgery.
Background
The eyeball is an important visual organ of the human body and is connected with the orbit wall by means of the orbit fascia and the ligament. Six extraocular muscles are attached to the eyeball wall to regulate the rotation movement of the eyeball. The orbit fat lining is arranged around the eyeball, so that the eyeball has no fixed supporting point in the orbit due to the special structural relation between the eyeball and the orbit wall, which is equivalent to a 'suspension' state from the anatomical aspect. The eyeball activity is closely related to the size of the visual field, and the larger the activity is, the larger the visual field is. Therefore, in order to meet the requirement of visual function, the device has larger activity and can complete large-angle multidirectional rotation.
In many ophthalmic operations, such as removal of foreign cornea, lamellar cornea, cataract, and intraocular surgery, the eye surface or the ocular surface should be treated accordingly. In the process of separating the scleral tunnel or deep lamellar keratoplasty plate layer by cataract operation, under the condition that the eyeball is not fixed, the eyeball is difficult to operate due to the fact that the eyeball mobility and the operator lack of a fixed fulcrum, and the eyeball can rotate along with the force application direction when force is applied. Currently, in ophthalmic surgery, an ophthalmic forceps is mainly used for fixing the eyeball to clamp the contralateral conjunctiva. The method has the following defects: 1. the conjunctiva tissue of the eye is relaxed, the eyeball mobility is larger, and the clamping range of the ophthalmic forceps is smaller, so that the method can not fix the eyeball well, and the auxiliary effect on operation is smaller; 2. the conjunctiva tissue is soft and fragile, and in the ophthalmic operation process, the ophthalmic forceps are sharp and favorable instruments, and the force for clamping and tearing the conjunctiva needs to be increased under the condition of pursuing the fixing effect. Therefore, the eye fixing method is very easy to damage the conjunctiva of eyes, and causes additional damage.
Chinese patent CN201710373U discloses an eyeball fixer, including elastic fastening strip and two eyeball covers, be equipped with the pincers platform on the diagonal clamp arm, eyeball cover side is equipped with the opening that runs through, and elastic fastening strip band-pass is opened and is run through two eyeball covers side by side, and elastic fastening strip both ends are equipped with fastener, and this patent has solved patient eyeball in the CT scanning involuntary rotation's problem, utilizes the fastener of elastic fastening strip, can adjust according to patient's head size, and the eyeball cover can slide on elastic fastening strip, according to patient's interpupillary distance's size, adjusts the distance of two eyeball covers. The eyeball fixer is mainly used for fixing the eyeball when the patient wakes up and is suitable for fixing the eyeball when certain ophthalmic examination, and cannot be used for fixing the eyeball in the operation process.
Chinese patent CN103310681a discloses an isolated eyeball fixer, including ice chest, washing drainage tube, rectus muscle mounting, set up in this ice chest and with wait to place eyeball shape assorted recess, be equipped with drainage hole in the recess bottom, washing drainage tube one end is connected to drainage hole, its other end wears out from ice chest bottom, rectus muscle mounting with wait to place the rectus muscle distribution position of eyeball correspondingly set up in the outside at recess notch edge, and make rectus muscle mounting with wait to place the attachment point of rectus muscle of eyeball with isolated eyeball fixer's horizontal plane is consistent. The in-vitro eyeball fixer is suitable for in-vitro eyeballs and cannot be used for in-vivo eyeballs.
Currently, there is no instrument clinically available for intraoperative eye fixation alone. Therefore, in order to reduce the difficulty of the operation and shorten the operation time, development and design of an instrument for assisting in fixing the eyeball in the ophthalmic operation are needed, but no report is made on the instrument at present.
