Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a perforated ophthalmic strabismus hook. Background Technology

[0002] An ophthalmic strabismus hook is a tool specifically designed for ophthalmic surgery, used to pull on the eye muscles.

[0003] The utility model patent with authorization announcement number CN207821993U discloses an ophthalmic strabismus hook, which includes a handle, a vertical hook body and a horizontal hook body. The two ends of the vertical hook body are connected to the handle and the horizontal hook body respectively. The end of the horizontal hook body is provided with a "C"-shaped lead hook. One end of the lead hook is connected to the horizontal hook body, and the other end has a gap with the horizontal hook body to form a line inlet.

[0004] The "C"-shaped hook at the end of the horizontal hook body in the aforementioned patent pulls on the eye muscles and causes eye tissue movement during the threading process. During this process, external air enters the tissue and cannot be expelled in time, causing gas accumulation and emphysema, which compresses and damages the eye tissue. To solve the drawbacks of the above technology, we propose a perforated ophthalmic strabismus hook. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a perforated ophthalmic strabismus hook.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An ophthalmic strabismus hook with a hole includes a strabismus hook mechanism and a disinfection tank mechanism. The strabismus hook mechanism includes an L-shaped hook body and a handle. A hexagonal screw block is fixedly installed on the upper side of the L-shaped hook body. A threaded connecting cylinder is fixedly installed on the upper end of the hexagonal screw block. The threaded connecting cylinder is screwed to the lower end of the handle. A circular protrusion is fixedly installed on the lower end of the L-shaped hook body. A threading hole is provided on the circular protrusion. A through hole is provided inside the L-shaped hook body. The through hole extends to the inside of the threading hole. A plurality of pressure equalization holes are provided on the side wall of the L-shaped hook body. The pressure equalization holes are connected to the through hole.

[0008] Furthermore, several protrusions are evenly distributed on the side wall of the handle.

[0009] Furthermore, a hanging ring is fixedly connected to the upper end of the handle.

[0010] Furthermore, both the handle and the L-shaped hook are made of stainless steel.

[0011] Furthermore, the disinfection tank mechanism includes a disinfection tank, a circulation pump is fixedly installed on the side wall of the disinfection tank, the output end of the circulation pump passes through to the inside of the disinfection tank and a plug-in tube is installed on the output end of the circulation pump, and a return bend is installed between the disinfection tank and the suction end of the circulation pump.

[0012] Furthermore, an inner ring rubber ring is provided on the inner side of the plug-in cylinder.

[0013] Furthermore, a power supply cable is electrically connected to the side of the disinfection tank, and a plug is fixedly installed at the end of the power supply cable.

[0014] Compared with related technologies, the perforated ophthalmic strabismus hook proposed in this utility model has the following beneficial effects:

[0015] In this utility model, a perforated ophthalmic strabismus hook is provided. The strabismus hook mechanism consists of an L-shaped hook body and a handle. The L-shaped hook body can be screwed off from the upper side of the handle for easy cleaning and disinfection. The L-shaped hook body has a suture hole. When it is necessary to perform operations such as traction or suturing of eye tissue, the suture hole allows the doctor to pass the suture through the hook body more easily. The doctor does not need to spend a lot of time trying to bypass the suture from the end of the hook body or other positions, but can directly pass it through the hole, which greatly saves surgical time and improves surgical efficiency.

[0016] In addition, there is a through hole inside the threading hole. During the operation, there is an equalizing hole on the side wall of the L-shaped hook body, which is connected to the inside of the threading hole through the through hole. In ophthalmic surgery, the eye tissue may produce exudate or blood and other fluid accumulation. The through hole can provide a drainage channel for these fluids, allowing them to flow out smoothly and avoiding the accumulation of fluid from affecting the surgical field and eye tissues. This helps to keep the surgical area clear, making it easier for doctors to observe and operate, and can also reduce the risk of postoperative infection.

[0017] During the procedure, gas may enter the interstitial space of the eye. The through hole inside the suture hole can release gas, preventing gas from accumulating and forming emphysema, which could compress and damage the eye tissue. Timely gas release can maintain the normal physiological state of the eye tissue and promote postoperative recovery. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] Reference Figure 1-7 A perforated ophthalmic strabismus hook includes a strabismus hook mechanism 1 and a disinfection tank mechanism 2. The strabismus hook mechanism 1 includes an L-shaped hook body 11 and a handle 18. A hexagonal screw block 12 is fixedly installed on the upper side of the L-shaped hook body 11. A threaded connecting cylinder 13 is fixedly installed on the upper end of the hexagonal screw block 12. The threaded connecting cylinder 13 is screwed to the lower end of the handle 18. A circular protrusion 14 is fixedly installed on the lower end of the L-shaped hook body 11. A threading hole 15 is opened on the circular protrusion 14. A through hole 16 is provided inside the L-shaped hook body 11. The through hole 16 extends to the inside of the threading hole 15. Several pressure equalization holes 17 are opened on the side wall of the L-shaped hook body 11. The pressure equalization holes 17 are connected to the through hole 16.

[0028] In this method, the disinfection tank mechanism 2 includes a disinfection tank 21, a circulation pump 22 is fixedly installed on the side wall of the disinfection tank 21, the output end of the circulation pump 22 passes through to the inside of the disinfection tank 21 and a plug tube 23 is connected to the output end of the circulation pump 22, and a return bend 25 is connected between the disinfection tank 21 and the suction end of the circulation pump 22.

[0029] With the above-described configuration, the insertion tube 23 in the disinfection tank mechanism 2 facilitates the insertion of the threaded connecting tube 13 on the upper side of the L-shaped hook 11 into the inner side of the insertion tube 23. Subsequently, the circulation pump 22 is activated, drawing the disinfectant from the disinfection tank 21 and injecting it into the L-shaped hook 11 through the insertion tube 23. The disinfectant enters the through hole 16 inside the L-shaped hook 11 through the threaded connecting tube 13, and then flows out from the end of the through hole 16 and the pressure equalization hole 17, returning to the disinfection tank 21 to form a circulation. At the same time, the interior of the L-shaped hook 11 is thoroughly disinfected in the circulation path, making the L-shaped hook 11 safer during medical operations, avoiding postoperative infection of the eye tissue, and enhancing the safety of use.

[0030] In this method, an inner ring rubber ring 24 is provided on the inner side of the plug-in tube 23.

[0031] With the above-described configuration, the inner ring rubber ring 24 ensures that when the threaded connecting cylinder 13 on the upper side of the L-shaped hook body 11 is inserted into the inner side of the insertion cylinder 23, the inner ring rubber ring 24 can fit and abut against the threaded connecting cylinder 13, keeping the disassembly point between the insertion cylinder 23 and the threaded connecting cylinder 13 sealed. This allows the disinfectant to flow from inside the L-shaped hook body 11 during circulation, improving the disinfection efficiency inside the L-shaped hook body 11.

[0032] In this method, a power supply cable 26 is electrically connected to the side of the disinfection tank 21, and a plug 27 is fixedly installed at the end of the power supply cable 26.

[0033] With the above configuration, the power supply cable 26 provides power to the circulation pump 22 on the side wall of the disinfection tank 21.

[0034] In this method, several protrusions 19 are evenly distributed on the side wall of the handle 18.

[0035] With the above-described arrangement, several protrusions 19 are evenly distributed on the side wall of the handle 18, thereby increasing the surface roughness of the handle 18 and facilitating surgical operations.

[0036] In this method, a hanging ring 110 is fixedly connected to the upper end of the handle 18.

[0037] With the above-described configuration, the hanging ring 110 allows the entire squinting hook mechanism 1 to be attached to relevant appliances during daily use, facilitating the retrieval and placement of the squinting hook mechanism 1.

[0038] In this method, both the handle 18 and the L-shaped hook 11 are made of stainless steel.

[0039] With the above-mentioned design, both the handle 18 and the L-shaped hook body 11 are made of stainless steel, making the main body of the entire oblique hook mechanism 1 less prone to rust and avoiding rust contamination.

[0040] The working principle of the perforated ophthalmic strabismus hook provided by this utility model is as follows:

[0041] During use, the medical suture is passed through the suture hole 15, and the eye muscles are pulled by the L-shaped hook 11. The medical suture brought in through the suture hole 15 is used to suture the relevant tissues for eye correction. During suturing, the through hole 16 inside the suture hole 15 can release air to prevent air accumulation and emphysema, which can cause pressure and damage to the eye tissues. During the operation, the eye tissues may produce exudate or blood accumulation. The through hole 16 can provide a drainage channel for these fluids, allowing them to flow out smoothly and preventing fluid accumulation from affecting the surgical field and eye tissues. This helps to keep the surgical area clear, making it easier for doctors to observe and operate, and also reduces the risk of postoperative infection.

[0042] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
