Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an auxiliary suture forceps for precise positioning of extraocular muscle shortening. Background Technology

[0002] Extraocular muscle shortening is a common procedure in strabismus correction surgery. By shortening the length of the extraocular muscles and increasing their strength, the deviation of the eyeball can be effectively corrected. Before shortening the extraocular muscles, it is crucial to accurately locate and suture the new muscle insertion point; this is a key step for surgical success. Currently, this location process mainly relies on the surgeon's experience and visual estimation after measuring with a ruler, allowing for a certain margin of error when suture fixing. This method is not very precise and is easily affected by subjective factors. Furthermore, during suture fixing, the assistant's traction force on the muscle may change, causing the suture position to shift and affecting surgical accuracy.

[0003] Existing ophthalmic surgical instruments are inadequate for accurately locating new muscle insertions, and there is a lack of auxiliary tools to improve the accuracy of suture fixation. To further improve the precision and stability of extraocular muscle shortening surgery, there is an urgent need to develop a specialized surgical instrument that can assist in the precise location of new muscle insertions and stabilize suture fixation. Utility Model Content

[0004] To address the aforementioned shortcomings in existing technologies, this invention proposes a precision positioning auxiliary suture clamp for extraocular muscle shortening, aiming to improve the accuracy of new muscle insertion point positioning in extraocular muscle shortening surgery, reduce surgical errors, and enhance surgical outcomes. This suture clamp integrates precision measurement and stable clamping functions, which not only significantly improves the accuracy of new muscle insertion point positioning during extraocular muscle shortening surgery but also simplifies suturing procedures, reduces surgical difficulty, and has significant clinical application value.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A precise positioning and suture forceps for shortening extraocular muscles includes: a lower forceps head, an upper forceps head, a forceps neck, a shaft connection fixing buckle, a shaft connection surface, forceps legs, a forceps leg adjustment assembly, and a forceps handle. The bottom ends of the lower and upper forceps heads are connected to the upper end of the forceps neck, and the lower end of the forceps neck is connected to the upper end of the forceps legs. A shaft connection surface is provided at the shaft position of the upper end of the forceps legs, and a shaft connection fixing buckle is fixed on the shaft connection surface. The two forceps legs are connected through the shaft connection fixing buckle. The lower end of the forceps legs is connected to the forceps handle. A forceps leg adjustment assembly is provided between the bottom of the two forceps legs and the forceps handle.

[0007] The lower jaw and the upper jaw are provided with corresponding positions inside the lower jaw and the upper jaw, which can fit together and be fixed, and rough teeth that increase friction. The lower jaw has a lower pointed tooth groove and a lower inner rough teeth groove, and the upper jaw has an upper pointed tooth groove and an upper inner rough teeth groove.

[0008] When the upper and lower jaws are engaged, the toothed edge of the lower jaw engages with the toothed edge of the upper jaw, forming a complete fit. The upper and lower jaws are then fixed in place, thus achieving stable clamping of the target position of the extraocular muscles.

[0009] The upper clamp head is equipped with an outer crossbar, an inner crossbar, a scale line, a connecting rod, and a connecting line for convenient measurement. The scale line is set on the outer crossbar, and the inner and outer crossbars are horizontally opposite each other. One end of the connecting rod is connected to the end of the outer crossbar near the zero scale line, and the other end is connected to the end of the inner crossbar. One end of the connecting line is connected to the end of the outer crossbar away from the zero scale line, and the other end is connected to the other end of the inner crossbar. The connecting rod and connecting line are perpendicular to the inner and outer crossbars and horizontally opposite each other. During suturing, the lower clamp head is positioned below the extraocular muscle, and the upper clamp head is positioned above the extraocular muscle. The outer crossbar faces the distal end of the surgeon's operation, and the inner crossbar faces the proximal end. The connecting rod is positioned between the target muscle suture point and the original muscle insertion point. Precise measurement and positioning are achieved by aligning any point on the scale line with the target muscle suture point.

[0010] Furthermore, the upper clamp head also includes an outer fixing buckle and an inner fixing buckle. One end of the connecting line is connected to the outer crossbar via the outer fixing buckle, and the other end is connected to the inner crossbar via the inner fixing buckle. During suturing, the connecting line fixed by the outer and inner fixing buckles is located behind the target muscle suture position, allowing the muscle around the suture point to lie flat in the surgical field, thereby simplifying the suturing operation and reducing the difficulty of the surgery.

[0011] The jaw adjustment assembly includes a crossbar buckle and a crossbar tooth groove, which are respectively fixed to the inner sides of the two jaws. When the upper and lower jaws are closed, the jaws connected to the jaw handle control the engagement of the upper and lower jaws through the shaft connection surface, the shaft connection fixing buckle, and the jaw neck. The degree of engagement of the crossbar buckle and the crossbar tooth groove can adjust the tightness of the clamping engagement of the upper and lower jaws to adapt to different clamping needs.

[0012] Preferably, the crossbar teeth are configured as a threaded structure.

[0013] The beneficial effects of this utility model are:

[0014] This invention improves the accuracy of new muscle insertion point location in extraocular muscle shortening surgery by modifying the structure of the forceps head on both the inner and outer sides, thereby reducing surgical errors and enhancing surgical outcomes. This suture forceps integrates precision measurement and stable clamping functions, significantly improving the accuracy of new muscle insertion point location in extraocular muscle shortening surgery, simplifying the suturing process, and reducing surgical complexity. Based on clinical needs, it is of great significance for improving surgical efficiency and quality and is highly practical. Attached Figure Description
