Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a surgical pushing device for artificial foldable balloon implantation. Background Art

[0002] Rhegmatogenous retinal detachment is a common fundus disease in ophthalmology. The retina is located in the innermost layer of the eyeball wall. The three elements of vitreous traction, retinal tear formation, and vitreous liquefaction will eventually cause the retinal neuroepithelial layer to peel off from the eyeball wall. Retinal detachment will affect the eyeball wall's supply of nutrients to the retina, causing visual cell atrophy and decreased visual function, which seriously threatens vision. Surgical treatment is usually required, and the key to treatment is to close the retinal tear.

[0003] Foldable artificial balloon-assisted scleral external pressure surgery is a new surgical method for treating rhegmatogenous retinal detachment. Compared with traditional external pressure surgery, it has a shorter operation time, fewer operation steps, less damage to eye tissue, and faster postoperative recovery. The sclera is located in the outermost layer of the eyeball wall. This surgery mainly implants a foldable artificial balloon outside the sclera to make the scleral wall concentrically depressed, so that the retinal pigment epithelium is close to the retinal neuroepithelium at the detached hole, closes the hole, and promotes the repositioning of the detached retina; Foldable artificial balloon-assisted scleral external pressure surgery is suitable for patients with retinal detachment caused by retinal holes, with a short retinal detachment time, good retinal mobility, a single hole or multiple holes in the same quadrant, and located in the equatorial or peripheral retina. During the operation, a minimally invasive conjunctival incision is required first to fully separate the subconjunctival tissue from the scleral surface, and a foldable balloon is implanted at the corresponding part of the retinal hole and the scleral surface. After the balloon is inserted, it is filled with water. When the balloon is fully inflated, the position will shift and it needs to be adjusted to achieve the ideal pressure position.

[0004] In summary, the following technical problems exist in the current foldable artificial balloon-assisted scleral pressurization process: due to the anatomical characteristics of the orbit and the individual differences in the anatomy of the orbits and intraorbital tissues of different patients, the gaps between the eyeball and the periorbital soft tissue and orbital bone are different in size in various directions. The existing balloon adjustment tool has a fixed structure and size. When the gap between the eyeball and the surrounding tissue is small, the surgical space is limited, and the existing tools for assisting balloon implantation and adjustment are hindered during operation, which is inconvenient for the surgeon to operate and cannot implant and adjust the balloon to the optimal position. Summary of the invention

[0005] In view of the above-mentioned problems existing in the prior art, the present invention provides a surgical pushing instrument for artificial foldable balloon implantation, which can adjust the size of the entry end of the pushing balloon according to the size of the gap between the patient's eyeball and the eye socket, so that it can be easily operated in a smaller operating space. In a larger operating space, a larger contact area can be adjusted to ensure stable pushing.

[0006] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0007] A surgical pushing instrument for artificial foldable balloon implantation, comprising a control part, a size adjustment part and an arc adjustment part, wherein the size adjustment part is provided at the lower side of the control part, and the size adjustment part comprises a side middle rod and a side side rod, wherein four side middle rods are provided, and the four side middle rods are arranged in a cross shape, and a side rod is provided between two side middle rods, and the control part controls the side middle rod to expand outward or retract inward with the upper end thereof as the axis;

[0010] Furthermore, a connecting membrane is fixedly connected between the side middle rod and the side edge rod.

[0011] Furthermore, the control part includes a handle, a support rod is fixedly connected to the lower side of the handle, and the size adjustment part is arranged on the lower side of the support rod.

[0012] Furthermore, an upper groove is opened on the upper side of the side middle rod, the side middle rod is fixedly connected with a rotating shaft in the upper groove, the rotating shaft is fixedly connected with a fixing frame, the fixing frame connected to the four side middle rods is fixedly connected with a fixing frame, and the fixing frame is fixedly connected to the support rod.

[0013] Furthermore, an inner ring is provided inside the fixing frame, and the inner ring abuts against the side middle rod; an outer ring is provided outside the fixing frame, and the outer ring abuts against the side middle rod;

[0014] The fixed frame is provided with two push-pull side rods, the fixed frame is provided with side grooves matched with the push-pull side rods, and the two push-pull side rods are fixedly connected to the outer ring and the inner ring respectively.

[0015] Furthermore, a push-pull inner rod is provided in the middle position of the side center rod, and the push-pull inner rod is fixedly connected to the middle position of the arc plate. The arc plate is fixedly connected with a sliding column at a position corresponding to the side center rod and the side rod. Holes and grooves corresponding to the sliding columns are opened on the lower sides of the side center rod and the side rod, and the sliding columns are slidably connected in the holes and grooves on the lower sides of the corresponding side center rod and side rod.

[0016] Furthermore, an outer membrane is fixedly connected between the lateral middle rod, the lateral rod and the support rod.

[0017] Furthermore, the push-pull inner rod and the push-pull side rod extend upward in the support rod into the handle, the push-pull inner rod and the push-pull side rod are fixedly connected with a threaded column in the handle, the threaded column is threadedly connected with a dial wheel, and the handle has a corresponding slot hole at the dial wheel position.

[0018] Beneficial effects of the present invention:

[0019] A surgical pushing instrument for artificial foldable balloon implantation. When in use, the thumbwheels on the push-pull side rods on both sides of the inner rod of the push rod are rotated. After the thumbwheels are matched with the threaded columns by rotating the thumbwheels on the two push-pull side rods in opposite directions, one of the two push-pull side rods is moved downward and the other is moved upward. When the gap between the patient's eyeball and the orbital bone is large and the surgical operation space is large, the inner ring is pushed downward and the outer ring is moved upward, so that the side middle rod drives the side rod to extend outward, and vice versa, the size is folded to reduce the size to use the operation space with a smaller gap, and the elastic arc plate is stretched and shrunk to change the appropriate size according to the size of the space to push. The balloon is moved; then the dial on the push-pull inner rod in the middle is turned to adjust the distance between the highest point of the arc plate and the straight edges of the lowest points on both sides. During the change of the arc plate, the slide bar slides on the lower ends of the side middle rod and the side rod. The arc plate is fixed in position with the edges of the side middle rod and the side rod, and the push-pull inner rod and the slide bar work together to make the overall transition smooth, so that the arc plate fits the balloon, avoiding the problem of the arc plate center contacting the balloon line or the arc plate sides contacting the balloon line, so that after adjusting the size, it can maintain a good fit with the balloon, which is beneficial to the surgeon's balloon pushing work.
