Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a fixed clip for fixed-distance shearing of muscles in strabismus surgery. Background Art

[0002] Strabismus refers to a disorder in the coordinated movement of extraocular muscles, resulting in the inability of both eyes to fixate on the same object simultaneously. It is an eye disease caused by congenital or acquired factors. Since strabismus not only hinders the normal function of the eyes but also affects the patient's social life due to its strange appearance, accurate correction is very important.

[0003] In the prior art, surgery is commonly used to shear the muscles around the eyeball and then suture them to adjust and correct strabismus. The main steps are as follows: first, the body position is fixed and anesthesia is performed. Then, the medial canthal or lateral canthal bulbar conjunctiva is incised and separated from the subconjunctival tissue. The medial rectus muscle or lateral rectus muscle is hooked out using a strabismus hook. The bulbar conjunctiva and intermuscular membrane are incised to fully expose the medial rectus muscle or lateral rectus muscle. Then, a double-loop suture operation is performed on the muscle at a position behind the attachment point of the medial rectus muscle or lateral rectus muscle, the muscle is cut, and finally, the scleral surface behind the muscle attachment point is sutured.

[0004] Currently, forceps are used for both shearing and suturing of the eye muscles. However, the shearing length of the eye muscles is mostly determined by the experience of medical staff, and there is no precise quantitative guiding shearing structure. In strabismus correction surgery, if the muscle shearing amount is inaccurate, it is very likely that strabismus will still occur later, resulting in surgical failure. Moreover, when using forceps to hold the eye muscles, since one pair of forceps can only hold one segment of the sheared muscle, the other segment is in a free state, which greatly increases the difficulty of subsequent muscle suturing operation. Without a suture guiding structure, it is also very easy to suture the muscle fracture unevenly, thus hindering the smooth recovery of the subsequent fracture, and reducing the surgical success rate. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a fixed clip for fixed-distance shearing of muscles in strabismus surgery, to solve the problems in the prior art that the forceps for holding the eye muscles do not have a precise fixed-distance muscle cutting guiding structure and a clamping mechanism for simultaneously holding both ends of the truncated muscle and guiding the suture, resulting in the inability to stably hold both ends of the truncated muscle, the inability to cut the eye muscles at a fixed value, and the inability to smoothly guide the suture of the eye muscles, ultimately leading to high surgical operation difficulty and easy surgical failure.

[0006] The present invention is achieved through the following technical solutions:

[0007] An adjustable-distance shearing and fixing clip for strabismus surgery, characterized in that it comprises a fixing clip housing, inside which a central groove plate is fixedly arranged. A distance-fixed telescopic device is slidably arranged on the front of the central groove plate through a chute. A upper clamping plate is fixedly arranged at the bottom of the distance-fixed telescopic device. The distance-fixed telescopic device is fixedly connected to a vertical electric telescopic device through a sliding rod penetrating the central groove plate. A lower clamping plate is fixedly arranged at the bottom of the vertical electric telescopic device. The lower clamping plate and the upper clamping plate are slidably connected through a vertical chute. A central controller is fixedly arranged at the top of the fixing clip housing. The central controller is respectively connected to the distance-fixed telescopic device and the vertical electric telescopic device through wires.

[0008] Furthermore, the upper clamping plate and the lower clamping plate are both provided with suture guiding holes that are aligned with each other, and the inner sides of the upper clamping plate and the lower clamping plate are flush.

[0009] Furthermore, the chute is opened in the middle of the central groove plate, and the length of the chute ranges from 15 to 20 mm.

[0010] Furthermore, the distance-fixed telescopic device comprises a horizontally-oriented electric telescopic rod fixedly arranged on the right side of the central groove plate and a moving block fixedly arranged at the left end of the horizontally-oriented electric telescopic rod. The upper clamping plates are respectively fixedly arranged at the lower ends of the horizontally-oriented electric telescopic rod and the moving block. The upper clamping plates are all identical and parallel to each other.

[0011] Furthermore, the vertical electric telescopic device is fixedly connected to the lower clamping plate through a telescopic rod.

[0012] Furthermore, vertical chutes are opened on the back sides of the upper clamping plates. Vertical sliding blocks are slidably arranged in the vertical chutes, and the vertical sliding blocks are fixedly connected to the fronts of the lower clamping plates.

[0013] Furthermore, limiting sliding grooves are symmetrically opened above and below the chute on the back of the central groove plate. The vertical electric telescopic device is slidably arranged at the rear side of the limiting sliding grooves through limiting sliding blocks.

[0014] Furthermore, the bottom edge of the lower clamping plate is rounded.

[0015] Furthermore, an anti-slip gripping area is arranged on the surface of the fixing clip housing.

[0016] The beneficial effects of the present invention are as follows:

[0017] The present invention designs a strabismus surgical muscle fixed-distance shearing clamp that simultaneously has a precise fixed-distance muscle cutting guiding structure and a clamping mechanism that can clamp both ends of the severed muscle and perform suture guiding, which is beneficial to achieve cutting the eye muscle at a fixed distance value, greatly improving the smoothness of suturing the eye muscle, and greatly reducing the surgical operation difficulty through the suture guiding structure, and significantly improving the surgical success rate.

[0032] Such as Figure 1As shown in FIGS. -7, an embodiment provided by the present invention: A fixed clip for fixed-distance shearing of muscles in strabismus surgery, comprising a fixed clip housing 1, a central controller 2 fixedly arranged at the top of the fixed clip housing, a central groove plate 3 fixedly arranged inside the fixed clip housing, a sliding groove 4 opened in the middle of the central groove plate, a fixed-distance expander 5 slidably arranged on the front of the central groove plate through the sliding groove. The fixed-distance expander includes a horizontally arranged electric telescopic rod 6 fixedly arranged on the right side of the central groove plate and a moving block 7 fixedly arranged at the left end of the horizontally arranged electric telescopic rod. Upper clamping plates 8 are fixedly arranged at the lower ends of both the horizontally arranged electric telescopic rod and the moving block. The two upper clamping plates are completely identical and parallel to each other. Limiting sliding grooves 9 are symmetrically opened above and below the sliding groove on the back of the central groove plate. A vertical electric telescopic device 10 is slidably arranged at the rear side of the limiting sliding groove through a limiting sliding block. The vertical electric telescopic device is fixedly connected to a lower clamping plate 12 through a telescopic rod 11. Vertical sliding grooves 13 are opened on the back sides of the upper clamping plates. Vertical sliding blocks 14 are slidably arranged in the vertical sliding grooves. The vertical sliding blocks are fixedly connected to the front surfaces of the lower clamping plates. Sewing guide holes 15 that are aligned with each other are opened on both the upper clamping plates and the lower clamping plates. The inner sides of the upper clamping plates and the lower clamping plates are flush. The fixed-distance expander is fixedly connected to the vertical electric telescopic device through a sliding rod 16 passing through the central groove plate. The central controller is connected to the fixed-distance expander and the vertical electric telescopic device through circuits respectively.

[0033] When this embodiment is implemented, first start the central controller, so that the central controller controls the fixed-distance expander to expand and contract to the position of the target cutting value. Then control the vertical electric telescopic device to drive the lower clamping plate to descend, so that there is enough gap between the upper clamping plate and the lower clamping plate. Then insert the lower clamping plate into the gap under the eye muscle to be cut. Then control the vertical electric telescopic device to drive the lower clamping plate to rise through the central controller, so that the upper clamping plate and the lower clamping plate approach and squeeze to fix the eye muscle. After the fixation is completed, use a shearing tool to shear along the inner sides of the upper and lower clamping plates, then accurate fixed-value shearing can be achieved. After the shearing is completed, control the center to make the two groups of clamping plates on both sides approach until the inner sides are completely in contact with each other. Then use a suturing tool to suture along the suture guide openings in sequence. After the suturing is completed, control the upper and lower clamping plates to separate and withdraw the device.

[0034] This embodiment designs a fixed clip for fixed-distance shearing of muscles in strabismus surgery that simultaneously has a precise fixed-distance muscle cutting and guiding structure and a clamping mechanism that can simultaneously clamp both ends of the cut muscle and perform suture guiding. It is beneficial to achieve fixed-distance shearing of the eye muscle, greatly improves the smoothness of suturing the eye muscle, and significantly reduces the difficulty of surgical operation through the suture guiding structure, and significantly improves the surgical success rate.

[0035] In this embodiment, the bottom edge of the lower clamping plate is rounded, which is beneficial to avoid scratching the patient's eyeball during the clamping process.

[0036] In this embodiment, an anti-slip gripping area 17 is provided on the surface of the fixed clamp housing, which is beneficial for medical staff to hold and operate.

[0037] In this embodiment, rechargeable batteries are provided inside the central controller, the fixed-spacing expander, and the vertical electric expander.

[0038] In this embodiment, the length of the sliding groove ranges from 15 to 20 mm, and this range can ensure that the sliding distance meets the cutting distances of all eye muscles in strabismus surgery.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
