Description

Technical Field

[0001] This utility model relates to a dual-adjustable anal retractor. Background Technology

[0002] During anal surgery or examination, the anus needs to be retracted. Anal hooks are used during this process. For example, Chinese invention patent CN110403649A, entitled "An Automatic Anal Retractor," discloses an automatic anal retractor comprising a disc with a circular structure. Several hook handles are arranged on the outer side of the disc, perpendicular to the outer wall of the disc. A locking mechanism is provided near the side wall of the disc on each hook handle. A spring is tightly welded to one end of each hook handle near the center of the disc, and a pointed hook is tightly welded to the other end of the spring away from the hook handle. The locking mechanism includes a sliding tube with a fixed block tightly welded to its top. A hook handle through-hole is formed on the side wall of the fixed block, through which the hook handle passes and is slidably connected.

[0003] While the aforementioned patent achieves position adjustment of the pointed hook through a hook handle and locking mechanism, the adjustment requires one hand to hold the disc while the other hand simultaneously loosens the bolt and pulls the hook handle, making the operation rather cumbersome. Furthermore, due to the spring's elasticity, if one hand doesn't hold the hook handle while the other tightens the bolt, the spring easily resets, making it difficult to fix the hook handle in the intended position. Additionally, the inner diameter of the disc is fixed, sometimes requiring different sized retractors for different patients, causing inconvenience during surgery or examinations.

[0004] Based on the above issues, the applicant conducted research on these issues and thus this case came into being. Summary of the Invention

[0005] The purpose of this invention is to provide a more convenient and simpler double-adjustable anal retractor.

[0031] To better understand the technical solution of this utility model, the following description is provided in more detail with reference to the embodiments.

[0032] Reference Figures 1 to 2 A dual-adjustable anal retractor includes a circular body and a hook mechanism mounted on the circular body. The circular body comprises three arc-shaped blocks 10 connected end-to-end, forming a ring. Each arc-shaped block 10 has an arc-shaped adjustment groove 11 at both ends along its length. The adjustment grooves 11 on adjacent arc-shaped blocks 10 are the same size and aligned. Locking bolts 30 are provided on the adjustment grooves 11 to position adjacent arc-shaped blocks 10 together. During connection, one end of one arc-shaped block 10 is stacked on top of one end of another arc-shaped block 10 and locked together by the locking bolts 30. The arc-shaped block 10 is also provided with a support seat 12, which has a threaded hole. The hook mechanism includes a screw 22, a spring 40 connected to the screw 22, and a hook body connected to the spring 40. The threaded hole is arranged along the radial direction of the ring body. The screw 22 is axially movable in the threaded hole. By rotating the screw 22, the screw 22 can be axially moved along the threaded hole, thereby making the screw 22 approach or move away from the center of the ring body. After moving to the predetermined position, the screw 22 is positioned by the threaded engagement.

[0033] In a preferred embodiment of this utility model, the arc-shaped adjustment groove 11 extends from the upper surface to the lower surface of the arc-shaped block 10. The locking bolt 30 includes a gripping part 31, a threaded rod 32, and a nut 33. The threaded rod 32 is vertically inserted into the arc-shaped adjustment groove 11. The gripping part 31 facilitates direct rotation of the threaded rod 32. The nut 33 is used to cooperate with the gripping part 31 to clamp the arc-shaped block 10.
