Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a thyroid laparoscopic retractor. Background Art

[0002] In conventional open thyroid surgery, exposure of the surgical field is critical. To this end, a retractor must be used to pull apart the anterior cervical muscles in front of the thyroid gland. Sometimes, the anterior cervical muscles need to be severed to fully expose the thyroid gland. However, in laparoscopic surgery, conventional thyroid retractors are too large to be used. However, existing thyroid retractors still have the disadvantages of small laparoscopic field of view, poor flexibility, and inconvenient use. Utility Model Content

[0003] The purpose of the utility model is to provide a thyroid laparoscopic retractor in order to solve the above problems.

[0004] The utility model achieves the above-mentioned purpose through the following technical scheme: a thyroid laparoscopic retractor, comprising a U-shaped steel rod, a screw hole seat, a rotating handle, a screw rod, a rear bearing, a U-shaped cross rod, a front bearing and a support hook, wherein both ends of the U-shaped steel rod are arranged as retractor structures, and a screw hole seat is welded to the middle part of the U-shaped steel rod, the screw hole seat is threadedly connected to the screw rod part, and one end of the screw rod is rotatably connected to one end of the U-shaped cross rod through the rear bearing, and the other end of the U-shaped cross rod is rotatably connected to one end of the support hook through the front bearing.

[0005] Furthermore, the U-shaped steel rod is made of elastic material, and the rod bodies on both sides of the U-shaped steel rod are inclined inwardly by 15°.

[0006] Furthermore, a rotating handle is installed at the other end of the screw rod, and the screw rod is not limited to one length.

[0007] Furthermore, the support hook and retractor structures are respectively located on both sides of the surgical wound.

[0008] Furthermore, the U-shaped cross bar is rotated sideways and placed on one side to form an operation area with an unobstructed view.

[0009] Compared with the prior art, the advantages of the present invention are: by applying force inwards at both ends of the U-shaped steel rod, the hook structure can be placed on the surgical opening, and at the same time, the outward supporting force is used to increase the lateral width of the surgical opening, and the screw is driven by rotating the handle to push the U-shaped cross rod forward, thereby driving the supporting hook connected to the rotating U-shaped cross rod to move forward, which is beneficial to open the surgical opening, and by turning the U-shaped cross rod to one side to form an obstacle-free visual operating area, the problem of structure obstructing visual field and operating space is solved.

[0015] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0017] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0018] See also Figure 1-3As shown, a thyroid laparoscopic retractor comprises a U-shaped steel rod 1, a screw hole seat 2, a rotating handle 3, a screw rod 4, a rear bearing 5, a U-shaped cross rod 6, a front bearing 7 and a support hook 8, wherein both ends of the U-shaped steel rod 1 are set as a retractor structure 101, and a screw hole seat 2 is welded to the middle part of the U-shaped steel rod 1, the screw hole seat 2 is partially threadedly connected to the screw rod 4, and one end of the screw rod 4 is rotatably connected to one end of the U-shaped cross rod 6 through the rear bearing 5, and the other end of the U-shaped cross rod 6 is rotatably connected to one end of the support hook 8 through the front bearing 7.

[0019] The U-shaped steel rod 1 is made of elastic material, and both sides of the U-shaped steel rod 1 are inclined inward by 15°; a rotating handle 3 is installed at the other end of the screw rod 4, and the screw rod 4 is not limited to one length; the support hook 8 and the hook structure 101 are respectively located on both sides of the surgical wound; the U-shaped cross rod 6 is placed on one side by side rotation to form an unobstructed visual field operation area.

[0020] When the utility model is in use, force is applied inwards at both ends of the U-shaped steel rod 1 so that the hook structure 101 is placed on the surgical opening, and at the same time, the outward supporting force is used to increase the lateral width of the surgical opening.
