Description

Ophthalmic surgery thread cutting scissors

Technical Field

The invention relates to the field of medical equipment, in particular to a pair of medical equipment, namely an ophthalmic surgery wire cutter.

Background

Currently, the number of patients in clinical ophthalmic outpatient operations is increasing. Conventional postoperative stitches removing doctors need to hold scissors and cut off surgical sutures by the scissors. However, in actual practice, due to the sensitivity of the eyeball, when the wire cutter approaches the eyeball, the wire cutter often causes the resistance of the patient, and causes the careless blink action of the patient, thereby causing medical accidents. Meanwhile, the stitches removing doctor worrys about blinking actions of the patient in the stitches removing process, so that each time the operation stitches are cut off, the operation stitches removing time is prolonged, and eyeballs are dry and astringent.

In order to solve the problem, medical staff designs an ophthalmologic microscister detacher, a miniature camera is additionally arranged in front of scissors, an operation line is enlarged through the miniature camera, the cutter part of the wire-cutting scissors is designed to be small and miniaturized, and the combination of the miniature camera and the cutter part enables a detaching doctor to operate in front of a display screen.

Certainly, the incision of the knife edge of the thread cutting scissors is improved, the operation thread can be conveniently fixed through the incision and then cut off, and the series of designs can not avoid the blinking action caused by the psychological pressure of the patient.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide an ophthalmologic operation thread cutting scissors which can cut an operation thread and reduce blinking actions caused by psychological burden of a patient in the thread removing process.

In order to achieve the purpose, the invention is realized by the following technical scheme: an ophthalmic surgical wire clipper, comprising: the main shell is provided with an upper shell, a left shell and a right shell; the upper shell is provided with a diving mirror mounting position and a mounting knife position, and telescopic rods are arranged in the left shell and the right shell; an intermediate plate fixedly mounted in the main housing; and the wire cutter is arranged in the middle plate.

Further, the latent mirror includes latent mirror shell, fluoroscope, reflector and magnifying glass, latent mirror shell from the bottom up, fixed mounting has fluoroscope, reflector and magnifying glass in proper order. The eyes to be removed under the main housing cover can be clearly seen through the design.

Further, the wire cutting scissors are provided with a scissors portion, a connecting rod and a hand holding portion, the scissors portion, the connecting rod and the hand holding portion are connected, and the connecting rod is connected with the hand holding portion. Through this design, this structure can avoid the light to spread, reduces the light stimulation to the patient.

Furthermore, a sliding through groove is formed in the middle plate, and the scissors portion slides up and down in the sliding through groove. Through this design for the broken string is cut and can be reciprocated, convenient operation.

Further, still include the steady piece of straight line, the steady piece fixed mounting of straight line is in the installation sword position, slidable mounting has in the steady piece of straight line the portion of holding. The stability of holding portion has been kept through this straight line stable piece, has improved the security of cutting the broken string and cutting at the broken string in-process.

Further, the scissors portion includes stationary knife, rotating knife and cutter arbor, the cutter arbor end is equipped with stationary knife, rotating the knife rotation and installing on the cutter arbor. The structure is simple and direct.

Furthermore, the rotary knife also comprises a pull rope, one end of the pull rope is fixedly arranged on the rotary knife, and the other end of the pull rope is arranged in the hand-holding part. Through the connection mode, the rotary knife can rapidly cut off the surgical thread.

And further, the fluorescent agent is also included and respectively coated at the bottoms of the fixed knife and the rotating knife. In actual work, the fluorescent agent is coated in a surgical thread in a small amount, the distance between the surgical thread and the thread cutting scissors is observed through a latent mirror, and then the thread cutting scissors are operated to cut the surgical thread.

The beneficial effect of above-mentioned ophthalmic surgery thread trimmer is: (1) the glasses can be shielded by the upper shell, the left shell and the right shell which are arranged on the main shell, so that the patient can not see the cut of the scissors in the process of removing stitches, and the patient has no psychological pressure in the operation. (2) All install the telescopic link in through left casing and the right casing for even the surface of eye unevenness passes through the flexible of telescopic link, keeps the balance of the main casing body. (3) The transmission of light is reduced by the installation of the middle plate, so that under the middle plate, the light becomes dark.
