Description

A foreign body pocket in the eyeball

technical field

The utility model relates to the technical field of medical equipment, in particular to a bag for foreign bodies in the eyeball.

Background technique

Ocular trauma combined with intraocular foreign body is a common disease in ophthalmology. Due to the damage of foreign body to ocular tissue, it is inevitable to remove intraocular foreign body in time when treating ocular trauma. At present, there are many instruments for removing intraocular foreign bodies, including extraocular and intraocular electromagnets for intraocular magnetic foreign bodies, intraocular foreign body forceps, and foreign body forceps for intraocular nonmagnetic foreign bodies. Although there are many types of foreign body forceps in the ball, the following problems still exist when using these instruments to remove foreign bodies in the ball: 1) The shape and size of foreign bodies are various, and there are few foreign body forceps suitable for grasping every foreign body; 2) The force for grasping foreign bodies is too light It is easy to make the foreign body fall off and damage the intraocular tissues such as the retina. Excessive force may easily damage the intraocular tissues around the foreign body; 3) The foreign body may slip again during the removal process, especially the foreign body with a smooth surface, and when adjusting the foreign body grasping direction ( Such as elongated foreign bodies) and foreign bodies are easy to slip when they are taken out through the scleral incision, which will damage the retina and other intraocular tissues again, and even cause massive intraocular hemorrhage, making the surgical field of vision unclear, interrupting or even failing the operation. Therefore urgently need to design a kind of instrument that cooperates with foreign body forceps.

Utility model content

The purpose of the utility model is to provide a foreign body bag in the eyeball which is easy to operate, convenient and practical, and the foreign body is not easy to fall off again.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a foreign body bag in the eyeball, including the body of the foreign body bag;

The body of the foreign body pocket includes a hollow handle and a handle connected with the handle, a metal wire is arranged in the handle; a sleeve is sleeved in the handle;

One end of the wire is connected to the grip bar, and the other end is connected to a dragline through a spring; the other end of the dragline is connected to an oval net bag;

The elliptical net bag includes an elliptical net basket, a net and a handle, the net is passed through the net basket, and the handle is connected to the end of the dragline;

The elliptical net bag is retracted in the casing by spring force when not in use, and the handle is pressed when in use, and the net bag stretches out of the casing, and the extent to which the casing is stretched out according to the degree of pressing the handle is also different. The heavier the said elliptical net bag is, the more it protrudes out of the sleeve pipe, and the net opening of the elliptical net bag is also larger, and vice versa.

The foreign body bag in the eyeball as described above, wherein, the handle of the oval mesh bag and the cannula are connected through threaded connection or clamping.

The foreign body bag in the eyeball as described above, wherein the net basket, the net and the metal wire are made of memory titanium alloy.

Compared with the prior art, the beneficial effects produced by the utility model are mainly reflected in:

1. The foreign body pocket in the eyeball of the present utility model effectively solves the problem that the foreign body is easy to slip in the process of grabbing the foreign body in the eye using foreign body forceps and electromagnets in the prior art by setting an oval net bag; it has the advantages of saving time and effort , Simple operation, small damage and strong practicability;

2. The foreign body bag in the eyeball of the present utility model can effectively reduce the risks brought by medical equipment to patients clinically.

Detailed ways

In order to facilitate the understanding of the purpose, technical solutions and effects of the utility model, the utility model will be further described in detail in combination with embodiments.

As shown in Figure 1, a foreign body pocket in the eyeball of the present utility model includes a foreign body pocket body 1; A metal wire 4 is provided; a sleeve 8 is sleeved in the handle 3; one end of the metal wire 4 is connected to the handle bar 3, and the other end is connected to a drag cable 6 through a spring 5; Connect an oval net bag 7 on the other end; Described oval net bag 7 comprises oval net basket 71, net 72 and handle 73, and described net 72 is set on described net basket 71, and described handle 73 is connected The end of the dragline 6; the oval net bag 7 is retracted in the casing 8 by the elastic force of the spring 5 when not in use, and the grip bar 3 is pressed during use, and the net bag stretches out of the casing 8, and according to the pressing grip The extent to which the rod 3 stretches out from the casing 8 is also different. The heavier the grip rod 3 is, the more the oval net bag 7 protrudes from the casing 8, and the mesh opening of the oval net bag 7 is also larger, and vice versa. .

The foreign body bag in the eyeball of the utility model, in the course of the operation, after the operator finds the position of the foreign body through the operating microscope, he cooperates with the foreign body forceps to hold the foreign body through the foreign body forceps; and then puts the net bag into the eye , press the handle 3 during use, the net bag extends out of the casing 8, then the foreign body pliers puts foreign objects into the mesh bag, finally loosens the handle 3, shrinks the oval mesh bag 7 into the casing 8, and takes out the Foreign matter pockets are enough.

The utility model relates to a pocket for intraocular foreign bodies. The elliptical net pocket is located in the casing when not in use, and the grip bar is pressed when in use, and the net pocket stretches out of the casing, and the stretching degree varies according to the amount of pressing force. , the greater the force, the more it stretches out, and at the same time the mouth of the net bag is also larger. After the pressure is stopped, the elastic net pocket retracts into the sleeve with the help of the spring, automatically tightens the net pocket, and fixes the foreign matter in the net pocket.

The foreign body pocket in the eyeball of the utility model effectively solves the problem that the foreign matter is easy to slip when taking the foreign matter in the eye by setting the oval net bag 7; it has the characteristics of saving time and effort, simple operation and strong practicability.
