Problems solved by technology
[0006] However, modern surgical methods not only inevitably produce blood in the patient's wound, but also burn the skin and generate smoke when the instrument cuts human tissue. If it is not removed in time, it will not only affect the doctor's field of vision, prolong the operation time, but also increase the pain of the patient. , and the smoke is often toxic and will be passively inhaled by medical staff, seriously affecting the health of medical staff
In addition, the surgical wound needs to be determined according to the size of the cut tissue, so it is difficult for a retractor of one size to meet the needs of various operations

Embodiment 1
[0021] The structure of the retractor device for surgery in this embodiment is as follows: figure 1 As shown, it includes a hook body 1 and a curved pull rod 2 extending from the middle of the hook body 1 . The hook body 1 is in the shape of a horizontally extending arc-shaped section, and the lower part of the convex outer surface of the arc-shaped section has a row of suction (smoke / liquid) holes 3 distributed at intervals. The pull rod 2 has a pipeline 4 communicating with the suction hole 3, and the tail of the pipeline 4 respectively extends out of a liquid discharge pipe 6 and a smoke exhaust pipe 7 controlled by a reversing valve 5 . When the reversing valve 5 closes the smoke exhaust pipe 7, the liquid discharge pipe 6 is pluggably connected with the negative pressure source, and the liquid discharge pipe 6, the pipeline 4 and the liquid suction hole 3 are connected to discharge blood and fluid; when the reversing valve 5. When the liquid discharge pipe 6 is closed, t...

The invention relates to a drag hook device for an operation and belongs to the technical field of medical instruments. The drag hook comprises a hook body and a bent drag bar extending from the middle of the hook body. The hook body is shaped like a horizontally-extending sheet with an arc-shaped cross section, and absorbing holes distributed at intervals are formed in the lower portion of the convex outer surface with an arc-shaped cross section. A pipeline respectively communicated with a drain pipe and an exhaust pipe through a reversing valve is arranged in the drag bar, and the drain pipe and the exhaust pipe are respectively provided with a pipe opening externally connected with a negative pressure source. The absorbing holes are communicated with the pipeline. By means of the drag hook device for the operation, operation parts can be fully exposed, in the process of use, an end handle is held, the reversing valve is turned by fingers, and then smoke and liquid can be discharged according to needs. Thus, smoke and water blood generated in the operation can be discharged timely, and the operation can be carried out smoothly.
Description
technical field [0001] The invention relates to a surgical tool, in particular to a retractor device for surgery, which belongs to the technical field of medical instruments. Background technique [0002] Surgical operations such as breast lumpectomy are indispensable to expose the surgical field of view by means of retractors. For this reason, people have invented all kinds of operation retractors. [0003] For example, the Chinese utility model patent with application number 201120205393.1 discloses a skin flap hook used in mastectomy, which includes a handle and a plurality of hooks arranged on the handle, and the hooks are hingedly arranged on the handle for A retractable retractor with adjustable length; since multiple retractors are provided, the defect of insufficient exposure of the surgical field of view using a single retractor can be overcome. [0004] The Chinese invention patent application with the application number 201010564809.9 discloses a breast flap arc...
