Detailed Description

The invention is further explained below with reference to the drawings and examples. In the following detailed description, certain exemplary embodiments of the present invention have been described by way of illustration only. Needless to say, a person skilled in the art will recognize that the described embodiments can be modified in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

As shown in fig. 1, the external path trabecula incision device comprises an operating handle 1, wherein one end of the operating handle 1 is connected with an incision supporting arm 2, the junction of the incision supporting arm 2 and the operating handle 1 is in arc angle smooth transition connection, an external path trabecula incision head 3 is fixedly arranged on the incision supporting arm 2, and the external path trabecula incision head 3 is positioned on one side of the incision supporting arm 2, which is far away from the operating handle 1. This embodiment is in cut under the effect of support arm 2, make outer way trabecula surely first 3 is in completely operating handle 1's the outside, and with be formed with certain distance between operating handle 1, can avoid the microscope field of vision down completely, make the operation process record clearly not have the fender, and make the art field expose completely to the efficiency and the quality of operation have been guaranteed, the emergence probability of furthest reduction postoperative complication.

Specifically, the incision support arm 2 includes a connection transition portion 21 connected to the operation handle 1, an incision head support portion 22 is fixedly connected to an end portion of the connection transition portion 21, the incision head support portion 22 is disposed in parallel with the operation handle 1 and is located below the operation handle 1, and the outer trabecular incision head 3 is provided at an end of the incision head support portion 22 away from the connection transition portion 21. The transverse connection function of the connecting transition part 21 realizes that the external path trabecular incision head 3 is sent out to form a certain distance with the operating handle 1, so that the incision part can be observed clearly when the operation is carried out.

In this embodiment, the connection transition portion 21 and the cutting head support portion 22 are connected in a smooth arc-angle transition manner. Because each part structure in the eye is fragile or weak, and the smooth transition arrangement between the two parts can avoid forming a sharp connecting line between the two parts, thereby reducing the accidental injury to the eye. The angle α between the connection transition portion 21 and the operating handle 1 is set to 90 to 135 °, in this embodiment, the angle α is set to 90 °, and when the length of the connection transition portion 21 is constant, the outgoing trabecular resection port 3 can be "sent out" to the farthest position from the operating handle 1.

In the present embodiment, the outer trabecular incision head 3 includes an incision probe 31 and a limit probe 32 respectively fixedly connected to the incision head support part 22, the limit probe 32 is disposed above the incision probe 31, and the junction between the incision probe 31 and the incision head support part 22 is in arc angle smooth transition connection, so that the outer end of the incision head support part 22 is relatively smooth and safe to use. Cut probe 31 with spacing probe 32 sets up to arc needle body structure and both parallel arrangement respectively, cut probe 31 with spacing probe 32's tip sets up to spherical structure's blunt head respectively, just spherical structure's maximum diameter is 0.2mm, can prevent cut probe 31 with when spacing probe 32 contacts with the eye, because both tip are too sharp-pointed and produce unexpected stabbing.

The length of operating handle 1 sets up to 50mm, the length of connecting transition portion 21 sets up to 6mm, cut probe 31 with spacing probe 32's length sets up to 9mm respectively, cut probe 31 with spacing between the probe 32 sets up to 1.5mm, and the comfort level according to specific operation of course can be adjusted with above-mentioned size to satisfy the use.

The surface of the operating handle 1 is provided with an anti-skid layer 4, and the anti-skid layer 4 is anti-skid lines formed on the surface of the operating handle 1 or covers the wear surface on the surface of the operating handle 1. Because when using, this embodiment is the operation of twirling formula, sets up behind the skid resistant course 4, can increase the hand with the increase friction of 1 piece of operating handle, the application of force when conveniently carrying out the operation makes the probability that the maloperation appears because of the phenomenon of skidding littleer.

As shown in fig. 2, the incision probe 31 has an incision blade 5 formed on an incision side surface thereof. Since the left and right sides of each eye need to be incised during the operation, the present embodiment is divided into two structures, i.e., a left structure and a right structure, which have the same main structure, and only the curving directions of the incising probe 31 and the position limiting probe 32 have slight difference, and the installation direction of the incising blade 5 on the incising probe 31 is slightly different.

As shown in fig. 3 and 4, in the present embodiment, the steps of sterilization, anesthesia, etc. are similar to those of the current trabeculectomy, and will not be described in detail herein, but the steps performed by the present embodiment are slightly modified, specifically: making an oblique corneal incision for anterior chamber puncture on a transparent cornea which is 1mm away from the corneal limbus on the temporal side by using a sharp line knife for later use; a blade is used for taking the rear edge of the corneoscleral edge migration belt as a center, extending 1mm forwards and backwards, and making a longitudinal incision with the length of about 2mm to cut the outer side wall of the Schlemm tube; the incisional probe 31 in this embodiment is inserted into the broken end of the Schlemm tube on one side, and the probe is pushed over the full length 4/5 without resistance; the operating handle 1 is twisted by hand to approach 90 degrees in the anterior chamber direction, so that the incision probe 31 and the limit probe 32 are parallel to the iris surface and incise the trabecular meshwork and slide into the anterior chamber, and simultaneously the probe is slowly and completely withdrawn outwards, and in the process again, the incised assembly is limited in the gap between the incision probe 31 and the limit probe 32 and is uncovered for a certain angle, so that the broken end of a Schlemm tube in the process is convenient, and the insertion of the limit probe 32 is convenient; the trabecula at one side is cut, and the trabecula at the other side is cut by the same method by using the device in the other direction; the operation after the trabecular incision is finished is the same as the operation of the trabecular resection operation at present, and comprises the steps of suturing a scleral flap, sterilizing, coating eye ointment, wrapping eyes by eye pads and the like, and is not described again.

The description of the present invention has been presented for purposes of illustration and description, and is not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to practitioners skilled in this art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
