Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a retractor for clinical use in general surgery. Background Art

[0002] A surgical retractor is a tool used by surgeons during surgery, usually to grab and pull tissues or organs for operation. This tool is usually made of medical stainless steel and has a special design that can accurately grab and move tissues during surgery to help doctors complete surgical operations.

[0003] Most of the current general surgery clinical retractors can be adjusted in length and height during use. However, due to the unstable wound position during surgery and to facilitate the doctor's surgical operation, the retractor angle needs to be properly adjusted. However, the existing retractors are not convenient for angle adjustment control, and the retractors cannot be temporarily and quickly installed on different operating tables, which affects the convenience and functionality of the retractor.

The mounting plate 201 is installed at the top of the fixed frame 1. The rotating handle 202 is installed on the outside of the mounting plate 201. The threaded rod 203 is fixedly connected to the outside of one side of the rotating handle 202. The threaded seat 204 is sleeved on the outside of the threaded rod 203. A limiting rod 205 is inserted into the inside of the threaded seat 204.

[0029] The lateral adjustment seat 3 is connected to the bottom end of the moving mechanism 2, the threaded rod 203 is threadedly connected to the threaded seat 204, the limit rod 205 is slidably connected inside the threaded seat 204, and the rotating handle 202 is fixedly connected to the outside of the threaded rod 203 by screws.

[0030] Specifically, after the rotating handle 202 is rotated, the threaded rod 203 is driven to rotate. At this time, after the threaded rod 203 is threadedly connected with the threaded seat 204, the threaded seat 204 can be limited by the limiting rod 205 to enable it to be telescopically moved and adjusted.

[0031] From the above, it can be seen that after the connecting hook 505 is adjusted by the moving mechanism 2 and the lateral adjustment seat 3, its position and height can be adjusted to a suitable position, and then by rotating the fastening screw 504, the sliding block 503 can be limited and fixed after sliding inside the track groove 502, so that the angle of the connecting hook 505 can be flexibly adjusted, which is convenient for the connecting hook 505 to grab and move tissues.

[0032] Embodiment 2:

[0033] refer to Figure 2 and Figure 4 As shown, the bottom end of the lateral adjustment seat 3 is fixedly connected to the telescopic cylinder 4, the bottom end of the telescopic cylinder 4 is fixedly connected to the movable mechanism 5, the bottom end of the fixed frame 1 is installed with a fixing mechanism 6, the movable mechanism 5 includes a sliding track 501, a track groove 502 and a sliding block 503, the sliding track 501 is fixedly connected to the bottom end of the telescopic cylinder 4, the inside of the sliding track 501 is provided with a track groove 502, the inside of the track groove 502 is inserted with a sliding block 503, one side of the sliding block 503 is externally connected to a fastening screw 504, one side of the sliding block 503 is externally fixedly connected to a connecting hook 505, the sliding block 503 is slidably connected inside the track groove 502, the fastening screw 504 is threadedly connected to the outside of the sliding track 501, and the fastening screw 504 is slidably connected to the outside of the sliding track 501.

[0034] Specifically, by sliding the sliding block 503 on the track groove 502, the connecting hook 505 can be rotated at an angle, so that the connecting hook 505 can be conveniently grasped and moved during surgery after rotation.

[0035] refer to Figure 3 and Figure 4 As shown, the fixing mechanism 6 includes a sleeve seat 601, an adjusting screw 602 and an abutment piece 603.
