technical field

The invention relates to tweezers, in particular to an FCB clamping tweezers.

Background technique

Foldable Capsular Vitreous Body (FCVB) is an innovative product developed and produced by Guangzhou Satellite TV Bo Biotechnology Co., Ltd. (refer to patent CN101386203B). The product consists of balloon, drainage tube, drainage valve, etc. , The basic material is made of imported silica gel that has been safely used in the human body for more than 20 years. It is used for intraocular implantation to treat severe retinal detachment that cannot be treated with existing vitreous substitutes. It has been widely used in clinical practice at home and abroad. At the same time, FCVB can also be implanted into the sclera surface as a foldable capsule buckle (FCB), by filling the sclera with normal saline to press the sclera, assisted freezing or laser closure of the hole, and play a role in the treatment of rhegmatogenous retinal detachment (RRD). ) effect.

At present, there is no special clamping forceps for FCB implantation and treatment of RRD. The general-purpose micromanipulation forceps are easy to damage the FCB due to the sharp end, which results in a waste of resources. Because the FCB is expensive, it also increases the cost of treatment; at the same time, in the implementation of When FCB is used to treat RRD, it is not possible to locate the retinal hole at the same time as implantation.

Therefore, there is a need for an FCB holding forceps, which is beneficial to prevent the damage of the FCB, and can locate the retinal hole position while the FCB is implanted.

SUMMARY OF THE INVENTION

In view of this, the purpose of the present invention is to provide an FCB holding forceps, which is beneficial to prevent the damage of the FCB, and can locate the position of the retinal hole while the FCB is implanted.

In order to achieve the above purpose, the present invention provides an FCB clamping tweezers, comprising a first tweezer handle and a second tweezers handle arranged in parallel, one end of the first tweezers handle is fixedly connected with one end of the second tweezers handle, the The other end of the first forceps handle is connected with a first forceps tip, and the other end of the second forceps handle is connected with a second forceps tip;

As a further improvement to the above technical solution, the diameter of the large-diameter end of the pressing protrusion is 1.5-1.7 mm, and the diameter of the small-diameter end is 1.1-1.3 mm.

As a further improvement to the above technical solution, the edge of the small diameter end of the pressing protrusion is smooth.

As a further improvement to the above technical solution, the first tweezers and the second tweezers are arc-shaped, the axis of the first clamping disc is arranged along the radial direction of the first tweezers, and the second clamping The axis of the disc is arranged in the radial direction of the second forceps tip.

As a further improvement to the above technical solution, the first tweezer handle and the first tweezer head are integrally formed, and the second tweezer handle and the second tweezer head are integrally formed.

As a further improvement to the above technical solution, the first tweezer handle and the second tweezer handle are both provided with a plurality of through holes.

Through the above disclosure, the present invention has the following beneficial technical effects:

In the FCB clamping forceps provided by the present invention, when in use, the doctor holds the first forceps handle and the second forceps handle and exerts an opposing force through fingers, and the first forceps handle and the second forceps handle move relatively to drive the first forceps head It moves relative to the second tweezers, thereby driving the first clamping disc and the second clamping disc to move relative to each other. The FCB between the first clamping disc and the second clamping disc is gradually clamped, and the first clamping disc is The inner disk surface of the first clamping disk and the inner disk surface of the second clamping disk are respectively in contact with the two sides of the FCB. Due to the large contact surface, the local stress of the FCB is effectively reduced, thereby helping to prevent the damage of the FCB; The top pressure protrusions are added on the outer disk surface, and the top pressure protrusions can be aligned with the retinal holes, so that the retinal holes can be located at the same time when the FCB is implanted.
