Description

Technical Field

[0001] This utility model relates to the field of strabismus hook technology, and in particular to a safe positioning strabismus hook for extraocular muscle drug injection. Background Technology

[0002] Compared to strabismus correction surgery, extraocular muscle injection therapy for strabismus offers advantages such as greater safety, minimal invasiveness, shorter anesthesia time, less postoperative pain, and better patient tolerance. Currently, botulinum toxin is the most widely used drug to weaken extraocular muscle strength, playing an important role in the adjunctive treatment of small-angle strabismus, post-endoscopic strabismus, and strabismus correction surgery.

[0003] Traditional surgery requires two surgeons: an assistant uses a strabismus hook to expose the extraocular muscles, while the surgeon injects the needle while it is suspended in the air. This lack of effective depth control introduces certain surgical risks. This new invention allows for single-surgery, enabling the removal of extraocular muscles and exposure of the surgical field, making the procedure more convenient, accurate, and safer. Furthermore, this safety-positioning strabismus hook completely encloses the extraocular muscles, protecting the underlying sclera and helping the surgeon assess the needle depth, thus avoiding the risk of scleral perforation.

[0026] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0027] Example 1

[0028] like Figures 1-4As shown, in order to solve the existing problems, this utility model discloses a safety positioning strabismus hook for extraocular muscle drug injection, including an upper end 1 of the handle, a lower end 2 of the handle slidably connected to the bottom of the upper end 1, a square groove 3 connected to the end of the lower end 2 away from the upper end 1, the square groove 3 including a bottom surface 301, an inner sidewall 303 connected to the side of the bottom surface 301 near the lower end 2 of the handle, an outer sidewall 302 connected to the side of the bottom surface 301 away from the lower end 2 of the handle, and a plurality of anti-slip pads 4 provided on the outer side of the upper end 1 of the handle.

[0029] The specific working principle is as follows: This structure enables a single person to pull out the patient's extraocular muscles, reducing the difficulty of the operation and the number of necessary medical staff.

[0030] When this device is in use, medical staff hold the upper end 1 of the handle. The anti-slip pad 4 can prevent medical staff from slipping during the operation.

[0031] The structure of the lower end 2 of the handle and the square groove 3 allows the extraocular muscles to be hooked out, facilitating subsequent surgical procedures.

[0032] In actual use, the sliding rod 704 can control the extension and retraction of the lower end 2 of the handle, thereby adjusting the device to a suitable length. When extension and retraction adjustment is required, the sliding rod 704 is slid towards the upper end 1 of the handle away from the lower end 2 of the handle. At this time, the spring 708 is compressed. Due to the structure of the inclined groove 705, the sliding rod 704 moves upward during the sliding process, thereby causing the limiting rack 707 at the bottom of the sliding rod 704 to separate from the rack 701. At this time, the rack 701 can slide freely. The structure of the return spring 5 allows the rack 701 to automatically extend outward, thereby reducing the difficulty of extension and retraction adjustment.

[0033] After the square groove 3 is pressed against a certain point, pushing the upper end 1 of the handle can achieve the telescopic sliding effect of the lower end 2 of the handle. When the lower end 2 of the handle slides to a suitable position, the sliding rod 704 is released. Under the action of the spring 708, the sliding rod 704 slides towards the lower end 2 of the handle. At this time, the limiting rack 707 approaches the rack 701 and then meshes with it. At this time, the rack 701 cannot slide freely, thus achieving the locking effect on the lower end 2 of the handle.

[0034] Example 2

[0035] like Figures 1-4As shown, in order to solve the existing problems in this embodiment, based on the same concept as the above embodiment one, the safety positioning strabismus hook for extraocular muscle drug injection further includes: the upper end 1 of the handle is hollow inside, the upper end 1 of the handle is provided with a rebound spring 5, the upper end 1 of the handle is connected with a sliding limiting member 6, and the upper end 1 of the handle is connected with a locking member 7.

[0036] Furthermore, the locking component 7 includes a rack 701 connected to the lower end 2 of the handle. The rack 701 has a limiting groove on its side, and the inner wall of the limiting groove is slidably connected to the sliding limiting member 6. The upper end 1 of the handle has a sliding groove 702 on its side, and a sliding limiting block 703 is provided on the inner wall of the sliding groove 702. The sliding limiting block 703 has an inclined groove 705 on its side, and a sliding rod 704 is slidably connected to the inner wall of the sliding groove 702. A limiting member 706 is connected to the side of the sliding rod 704, and the limiting member 706 is slidably connected to the inner wall of the inclined groove 705.

[0037] Specifically, the end of the rack 701 away from the lower end 2 of the handle is connected to the rebound spring 5, the bottom of the sliding rod 704 is connected to the limiting rack 707, the limiting rack 707 is in contact with the rack 701, the side of the limiting rack 707 is connected to the abutment spring 708, and the other end of the abutment spring 708 is connected to the inner wall of the upper end 1 of the handle.

[0038] The height of the inclined groove 705 near the abutment spring 708 is higher than the height of the end away from the abutment spring 708. The tooth pitch of the limiting rack 707 and the rack 701 is the same, and the limiting rack 707 and the rack 701 mesh with each other.

[0039] Several anti-slip pads 4 are symmetrically arranged at equal intervals on both sides of the upper end 1 of the handle, and the outer end face of the anti-slip pads 4 is provided with a buffer layer.

[0040] The retractable lower end 2 structure makes the device easy to carry and store during actual use, reduces the risk of breakage of the lower end 2, and keeps the lower end 2 clean. The automatic rebound structure makes it easy for medical staff to use and operate.

[0041] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
