Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and in particular to an auxiliary suture device for ophthalmic surgery. Background Technology

[0002] A growing number of workers in agriculture, forestry, and factory production are experiencing iris root transection due to accidental injuries during construction. Iris root transection can cause decreased vision, monocular diplopia, photophobia, and other discomforts. In clinical practice, the primary treatment for traumatic iris root transection is surgical suturing. However, this surgery typically requires intraoperative suture threading, often involving cutting 10-0 nylon sutures and threading the cut ends through a 29G hollow needle. This suture threading is time-consuming, laborious, and eye-intensive. Furthermore, the sutures often slip due to their thinness, requiring two or more re-threading attempts, increasing the difficulty of the surgery, prolonging the operation time, adding to the procedures, and increasing the risk of infection. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an auxiliary suture-threading device for ophthalmic surgery, which enables quick and convenient suture threading during surgery.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An auxiliary suture-threading device for ophthalmic surgery includes a suture-threading rod and a grip tube extending through both ends. One end of the grip tube is detachably connected to a hollow needle, and the other end is detachably equipped with a fixing plug. The suture-threading rod is located inside the grip tube, with one end detachably connected to the fixing plug and the other end equipped with a fixing ring for connecting the suture. Both the fixing ring and the suture-threading rod can freely pass through the hollow needle. During the operation, the suture is first connected to the fixing ring, and then the suture-threading rod drives the fixing ring through the hollow needle to quickly thread the suture onto the hollow needle. The entire suture-threading process is simple and convenient, thereby reducing the difficulty of the surgical operation and facilitating the surgeon's operation.

[0006] Preferably, the retaining ring is screwed onto the threading rod.

[0007] Preferably, the threading rod is a metal rod, and the end of the metal rod away from the fixing plug is wound to form a fixing loop.

[0008] Preferably, the threading rod is inserted into the fixing plug, and the fixing plug is made of sponge or silicone.

[0009] Preferably, the fixing plug and the grip are frustoconical, with the smaller end serving as the insertion end.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This utility model, through the cooperation of a gripping sleeve, a fixing plug, a threading rod, and a fixing ring added to the hollow needle head, allows for quick threading of sutures onto the hollow needle head during surgery. The entire threading process is simple and convenient, thereby reducing the difficulty of surgical operation and making it easier for the surgeon to perform the operation.

[0012] Figure 1 This is a cross-sectional structural diagram of the present invention.

[0013] The attached diagram is labeled as follows: 1. Threading rod, 2. Handle tube, 3. Fixing plug, 4. Hollow needle, 5. Sewing thread, 6. Fixing ring. Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0015] like Figure 1 The illustrated auxiliary suture device for ophthalmic surgery includes a suture rod 1 and a grip tube 2 extending through both ends. One end of the grip tube 2 is detachably connected to a hollow needle 4, and the other end is detachably equipped with a fixing plug 3. The suture rod 1 is located inside the grip tube 2, with one end detachably connected to the fixing plug 3 and the other end equipped with a fixing ring 6 for connecting sutures 5. Both the fixing ring 6 and the suture rod 1 can freely pass through the hollow needle 4. Specifically, by the cooperation of the grip tube 2 added to the hollow needle 4 with the fixing plug 3, the suture rod 1, and the fixing ring 6, the sutures 5 can be quickly threaded onto the hollow needle 4 during surgery. The entire suture threading process is simple and convenient, thereby reducing the difficulty of surgical operation and facilitating the surgeon's operation.

[0016] The above-mentioned ophthalmic surgical suture device has the following two usage methods:

[0017] The steps for Method 1 are as follows:

[0018] 1.1 Before the surgery begins, thread the suture 5 into the fixing ring 6 on the threading rod 1 and tie a knot;

[0019] 1.2. The thread 5 on the fixing ring 6 is completely passed through the hollow needle 4 and the handle 2 by the threading rod 1, and a sufficient length of thread 5 is pulled out.

[0020] 1.3 After assembling the threading rod 1 onto the fixing plug 3, assemble the fixing plug 3 onto the gripper 2;

[0021] 1.4 The surgeon begins the operation by holding the grip tube 2.

[0022] The steps for method 2 are as follows:

[0023] 2.1 The surgeon makes a peripheral clear corneal incision on the side opposite to the iris detachment, holds the tube 2 and inserts the hollow needle 4 through the incision into the anterior chamber, through the root of the detached iris and out through the corresponding angle of the anterior chamber, conjunctiva, and sclera to the outside of the eye;

[0024] 2.2 Thread the sewing thread 5 into the retaining ring 6 on the threading rod 1 and tie a knot;

[0025] 2.3. The thread 5 on the fixing ring 6 is completely passed through the hollow needle 4 and the handle 2 by the threading rod 1, and a sufficiently long thread 5 is pulled out.

[0026] 2.4 After assembling the threading rod 1 onto the fixing plug 3, assemble the fixing plug 3 onto the gripper 2;

[0027] 2.5 The surgeon continues the surgery while holding the tube 2.

[0028] In some embodiments, the aforementioned retaining ring 6 is screwed onto the threading rod 1.

[0029] In some embodiments, the threading rod 1 is a metal rod, and the end of the metal rod away from the fixing plug 3 is wound to form a fixing ring 6.

[0030] As a preferred embodiment of the above, the threading rod 1 is inserted into the fixing plug 3, and the fixing plug 3 is made of sponge or silicone.

[0031] As a preferred embodiment of the above, the fixing plug 3 and the gripping cylinder 2 are frustoconical, with the smaller end serving as the insertion end.

[0032] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
