The utility model discloses only need adjust the pole and the folding rod that open and shut of mechanism, can follow the active state and become the stationary state, make things convenient for the doctor to realize strutting patient's incision for a long time at the in-process of operation, utilize the safety protection effect of protective sheath, reduce the oppression of metal to skin for the wound heals fast.
Description
Technical Field
The utility model relates to a spreader, in particular to a spreader for endoscopic surgery.
Background
When a surgical operation is performed on the inside of a human body, after a superficial incision is cut, a doctor needs to pull the incision by using a medical retractor so as to operate the surgical position inside the human body. At present, medical drag hooks are pulled by medical personnel for a long time by hands, and the drag hooks can be released until internal operation is completed and the incision suturing stage is reached, so that the medical personnel are very tired in work, and the drag hooks occupy the space around an operating table, thereby increasing the inconvenience factor for operation of surgeons. Although the prior art has appeared the medical operation incision opening tool, the problems of inconvenient use, complex structure and incapability of effectively reducing the labor capacity of medical workers still exist, and the improvement is needed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a strut ware for endoscopic surgery solves the shortcoming that prior art exists.
The utility model discloses a following technical scheme realizes:
the utility model provides a strut ware for endoscopic surgery, its characterized in that, should strut the mechanism that opens and shuts that has a V font, the mechanism that opens and shuts includes the pole that opens and shuts that two symmetries set up, be provided with the folding rod that the symmetry set up between the pole that opens and shuts, two folding rod symmetries set up, the rotatable connection of one end of folding rod is on the pole that opens and shuts, and the other end is connected on a carriage, carriage internally mounted has a telescopic link, the periphery of telescopic link is equipped with a spring to the cover.
Furthermore, the opening and closing rod is rotatably connected with the folding rod through a pin shaft.
Furthermore, a layer of protective sleeve is arranged on the outer surface of the opening and closing rod.
Further, the protective sheath is a plastic protective sheath or a silica gel protective sheath.
The utility model discloses the beneficial technological effect who possesses is: the operation spreader of the utility model has the characteristic of convenient operation, and can be changed from a movable state to a fixed state only by adjusting the opening and closing rod and the folding rod of the opening and closing mechanism, thereby facilitating the doctor to spread the incision of the patient for a long time in the operation process; the operation spreader is in direct contact with the wound part, and the compression of metal to the skin is reduced by utilizing the safety protection effect of the protective sleeve, so that the wound is quickly healed.

Detailed Description
The following description of the embodiments will help the public to understand the present invention, but the specific embodiments given by the applicant should not be considered as limiting the technical solution of the present invention, and any changes in the definition of the components or technical features and/or in the form of the overall structure rather than substantial changes should be considered as the protection scope defined by the technical solution of the present invention.
As shown in fig. 1 and fig. 2, the spreader for endoscopic surgery has a V-shaped opening and closing mechanism, the opening and closing mechanism includes two symmetrically arranged opening and closing rods 1, folding rods 3 symmetrically arranged are arranged between the opening and closing rods, the opening and closing rods 1 and the folding rods 3 are rotationally connected through a pin, the two folding rods 3 are symmetrically arranged, and the rotationally connected means: the two connected components can rotate around a pin shaft, one end of a folding rod 3 is rotatably connected to an opening and closing rod 1, the other end of the folding rod is connected to a sliding frame 2, the sliding frame 2 is slidably arranged on a sliding rail 4, a telescopic rod 7 is arranged inside the sliding frame 2, a spring 8 is sleeved on the outer periphery of the telescopic rod 7, one end of the opening and closing rod 1 is rotatably arranged on a fixing plate 5, a holding end 6 is arranged on the fixing plate 5, and protrusions 9 are arranged on the sliding rail 4 at intervals, in the embodiment, the protrusions 9 are 1/4 circular, in other embodiments, the protrusions 9 can be semicircular, trapezoidal and the like, gaps among the protrusions 9 can accommodate the telescopic rod 7, when the sliding frame 2 slides through the gaps among the protrusions 9, the telescopic rod 7 pops up under the action of the spring 8 and is fixed among the protrusions 9 in a clamping manner, because the opening and closing rod 1, the sliding frame 2 and the folding rod 3 are rotationally connected through the locking shaft, when the telescopic rod 7 moves and is fixed among different bulges 9, the corresponding opening angle of the opening and closing rod 1 is changed, and the function of opening the incision of the surgical patient is achieved. The surface mounting that opens and shuts pole 1 has the one deck protective sheath (not shown in the figure), and in this embodiment, the protective sheath is plastics protective sheath or silica gel protective sheath, and in other embodiments, the protective sheath can select for use any material that can prevent to harm patient's skin, and the shape of protective sheath matches with the profile of opening and shutting the mechanism, can the gomphosis at the surface of opening and shutting the mechanism, has played the effect of skin and tissue around the protection operation patient incision.
Of course, the present invention can have other various embodiments, and those skilled in the art can make various corresponding changes and modifications according to the present invention without departing from the spirit and the essence of the present invention, and these corresponding changes and modifications should fall within the protection scope of the appended claims.
