Technical Field

[0001] The utility model belongs to the field of medical technology, and specifically relates to a novel surgical retractor. Background Art

[0002] During surgery, after the skin and muscles are cut open, retractors are used to pull the skin and muscles to both sides so that the surgical field in the middle is exposed. Surgical retractors are a commonly used tool in surgery.

[0003] Chinese patent application No. 202120845533.5 discloses a new type of surgical retractor, including a first support rod and a second support rod, wherein first retractors are fixedly installed under both end heads of the first support rod, and second retractors are fixedly installed under both end heads of the second support rod, and the angle between the first support rod and the second support rod can be adjusted by hinged connection of the first support rod and the second support rod with the connecting block, thereby adjusting the angle between the two first retractors on the first support rod and the two retractors on the second support rod, thereby facilitating the adjustment of the angle between the two first retractors and the two second retractors to adapt to different types of surgeries, and the angle between the first support rod and the second support rod can be fixed by a limiting device, and the pulling handle can directly pull the two first retractors on the first support rod and the two second retractors on the second support rod at the same time, thereby reducing the workload of medical staff during the operation and increasing work efficiency.

[0004] In the above-mentioned public patent, the two support rods are slidably connected to the handle through a connecting rod, which results in the inability to adjust the angle between the two support rods. The structure has defects and cannot be used normally. The spacing between the hooks on both sides is adjusted by rotating the two rotating blocks to drive the two copper tubes to move outward respectively. The operation is cumbersome and inconvenient to use. Utility Model Content

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that the adjustment component 6 includes a slide groove 61, a screw rod 62, a rotary block 63, a positioning block 64 and a slider 65. The slide groove 61 is opened inside the handle 1, the screw rod 62 is embedded inside the slide groove 61, the side end of the screw rod 62 is connected to the rotary block 63, the surface of the screw rod 62 is covered with a positioning block 64, and the top of the connecting rod 2 is connected to the slider 65.

[0032] Specifically, the threads of the two end surfaces of the screw rod 62 are in opposite directions, the surface of the slider 65 is in close contact with the inner wall of the slide groove 61 , and the two sliders 65 are symmetrically located inside the slide groove 61 .

[0033] By adopting the above technical solution, the positioning block 64 plays a positioning role, and the rotating block 63 drives the screw 62 to limit its rotation. Under the meshing connection between the screw 62 and the slider 65, the slide groove 61 limits the slider 65. Since the thread directions of the surfaces at both ends of the screw 62 are opposite, the two sliders 65 can respectively drive the connecting rod 2 to move toward each other, and the two support rods 3 move toward each other in the sleeve 7 to adjust the distance between the two side hooks 4. The adjustment operation is simple and the use effect is better.

[0034] When this embodiment is used, the positioning block 64 plays a positioning role, and the rotating block 63 drives the screw 62 to limit its rotation. Under the meshing connection between the screw 62 and the slider 65, the slide groove 61 limits the slider 65. Since the thread directions of the two end surfaces of the screw 62 are opposite, the two sliders 65 can respectively drive the connecting rod 2 to move toward each other, and the two support rods 3 move toward each other in the sleeve 7 to adjust the distance between the two side hooks 4. The adjustment operation is simple and the use effect is better.

[0035] The structure and usage principle of the handle 1, connecting rod 2, support rod 3, retractor 4 and sleeve 7 in the utility model have been disclosed in Chinese patent application No. 202120845533.5, which discloses a new type of surgical retractor. Its working principle is that the bottom ends of the two connecting rods 2 at the bottom of the handle 1 are connected to the support rod 3, and the retractor 4 at the bottom of the support rod 3 can pull the skin and muscles to both sides respectively, and the distance between the retractor 4 on both sides can be adjusted under the sliding connection between the support rod 3 and the sleeve 7.

[0036] Working principle and use process of the utility model: When the utility model is used, the bottom of the two connecting rods 2 at the bottom of the handle 1 are connected to the support rod 3, and the retractor 4 at the bottom of the support rod 3 can pull the skin and muscles to both sides for easy surgery. The positioning block 64 plays a positioning role, and the rotating block 63 drives the screw rod 62 to limit the rotation. Under the meshing connection between the screw rod 62 and the slider 65, the slide groove 61 limits the slider 65. Because the thread directions of the surfaces at both ends of the screw rod 62 are opposite, the two sliders 65 can respectively drive the connecting rod 2 to move toward each other, and the two support rods 3 move toward each other in the sleeve 7 to adjust the pull on both sides. The spacing between the hooks 4 is easy to adjust and has a better use effect. Under the elastic force of the spring 55 inside the support 56, the block 53 and the gear 52 are tightly engaged to position the angle of the retractor 4. The moving control block 54 drives the block 53 to separate from the gear 52. Under the rotating connection between the support rod 3 and the rotating groove 511, the angle between the retractor 4 on both sides can be rotated to adjust the positioning. The firm positioning can make the surgical retractor positioning more accurate and safer. The limit block 512 and the limit groove 513 are limited and rotated, and the connecting rod 2 can synchronously drive the support rod 3 to move. The reasonable structure can make the use of the device better.
