Abstract
Description
Technical Field
[0001] The present invention relates to the field of medical device technology, and more particularly to a laparoscopic surgery retractor and suspension device. Background Art
[0002] Existing laparoscopic minimally invasive technology has shortcomings when applied to breast surgery. In breast minimally invasive surgery, the structure of the breast is not like the digestive tract or respiratory tract structure with natural gaps. This results in the laparoscope being wrapped by breast tissue when entering the breast through the incision, limiting the surgical field that the laparoscope can observe, and it is not easy for doctors to observe the surgical situation through the laparoscope.
[0003] In the prior art, laparoscopic breast surgery equipment is equipped with an inflation device, which can pump carbon dioxide gas into the tumor area of the breast to expand a space that is large enough to accommodate the laparoscopic surgical instruments and provide a certain surgical field. In addition to being equipped with a robotic arm instrument control device, this laparoscopic breast surgery equipment is also equipped with an inflation device, making the equipment expensive.
[0004] Therefore, in order to save costs, when performing minimally invasive surgery in areas close to the skin surface, such as the thyroid or breast, auxiliary retractors can be used to create a larger surgical field for the laparoscope. The auxiliary retractors can lift up the skin or muscle groups on the surface of the surgical area, that is, lift up other tissues above the tissues that need to be operated on, and expand the field of view of the surgical area.
[0005] The auxiliary retractor is a right-angle or V-shaped structure composed of multiple metal connecting rods. During laparoscopic surgery, the auxiliary retractor extends under the muscles in the surgical area to hook up the muscles in the surgical area. After the auxiliary retractor is inserted, it is hung on the suspension bracket to complete the fixation. If the caliber of the auxiliary retractor is relatively thin, directly hanging the auxiliary retractor on the bracket will cause the auxiliary retractor to deform.
[0006] Therefore, in order to prevent the auxiliary retractor from being deformed during surgery, the present application provides a laparoscopic surgery retractor hanger and a suspension device. Summary of the invention

[0039] Embodiment 1
[0040] When performing minimally invasive surgery on areas close to the skin surface such as the thyroid or breast, an auxiliary retractor 4 can be used to create a larger surgical field for the laparoscope. The auxiliary retractor 4 can lift up the skin or muscle group on the surface of the surgical area, that is, lift up other tissues above the tissue to be operated on, thereby expanding the field of view of the surgical area.
[0041] Figure 3 It is a schematic diagram of the structure of the auxiliary hook. Figure 3As shown, the auxiliary hook 4 is a right-angle or V-shaped structure composed of multiple metal connecting rods. In laparoscopic surgery, the auxiliary hook 4 extends under the muscle group in the surgical area to hook up the muscle group in the surgical area. After the auxiliary hook 4 is inserted, it is hung on the suspension bracket to complete the fixation. If the caliber of the auxiliary hook 4 is relatively thin, directly hanging the auxiliary hook 4 on the bracket will cause the auxiliary hook 4 to deform.
[0042] In order to prevent the auxiliary retractor from deforming during laparoscopic surgery, the embodiment of the present application provides a laparoscopic surgery retractor hanger, including: a retractor fixer 1;
[0043] The retractor fixator 1 is provided with a retractor accommodating hole 12, and the hole axis of the retractor accommodating hole 12 and the auxiliary retractor 4 are matched, and the retractor accommodating hole 12 is used to fix the auxiliary retractor 4; the auxiliary retractor 4 is used to provide an operating field for laparoscopic surgery; the retractor fixator 1 is used to suspend the auxiliary retractor on the operating area bracket of the laparoscopic surgery.
[0044] Specifically, the inner wall of the hook receiving hole 12 of the hook fixer 1 is provided with threads, which are matched with the threads on the outer wall of the auxiliary hook 4 .
[0045] Furthermore, the hook fixer 1 also includes a hook mounting bolt 13, and a hook mounting screw hole is provided through the hole wall of the hook accommodating hole 12; the hook mounting screw hole and the axial direction of the hook accommodating hole 12 are perpendicular to each other, and the hook mounting bolt 13 is threadedly matched with the hook mounting screw hole.
[0046] In the embodiment of the present application, the retractor fixator 1 is hung on the surgical area support of laparoscopic surgery. Figure 6 As shown, after the auxiliary retractor 4 is arranged in the surgical area, the metal rod of the auxiliary retractor 4 is inserted into the retractor receiving hole 12. When the height of the auxiliary retractor 4 meets the requirements of the surgical operation, the retractor mounting bolt 13 is screwed into the retractor mounting screw hole. When the retractor mounting bolt 13 abuts against the auxiliary retractor 4, the auxiliary retractor 4 is clamped on the hole wall of the retractor mounting screw hole. The fixation is completed when the auxiliary retractor 4 does not fall off.
[0047] It should be noted that the auxiliary hook and the hook receiving hole are matched through the hole axis, and the fixing structure or method between the auxiliary hook and the hook receiving hole is not limited. The auxiliary hook and the hook receiving hole can be fixed by the hook mounting bolt 13 described in the embodiment of the present application, or by means of slot matching or thread matching.
[0048] Embodiment 2
[0049] Based on the laparoscopic surgical retractor suspension device shown in the first embodiment, in order to prevent the auxiliary retractor 4 from being deformed during surgery, the embodiment of the present application further provides a suspension device for a laparoscopic hand-assisted retractor.
[0050] Figure 1 It is a schematic diagram of the three-dimensional structure of the suspension device of the laparoscopic surgery auxiliary retractor shown in the embodiment of the present application.
[0051] like Figure 1 As shown, the suspension device shown in the embodiment of the present application includes: a hook fixer 1 and a fixer bracket 2.
[0052] Specifically, Figure 2 As shown in the three-dimensional structural schematic diagram of the hook fixer 1, the hook fixer 1 shown in the embodiment of the present application is provided with a hook accommodating hole 12, and the hook fixer 1 also includes a hook mounting bolt 13; the hole axis of the hook accommodating hole 12 and the auxiliary hook 4 are matched, and a hook mounting screw hole is provided through the hole wall of the hook accommodating hole 12; the hook mounting bolt 13 is threadedly matched with the hook mounting screw hole.
[0053] In the embodiments of the present application, Figure 6 As shown, after the auxiliary retractor 4 is arranged in the surgical area, the metal rod of the auxiliary retractor 4 is inserted into the retractor receiving hole 12. When the height of the auxiliary retractor 4 meets the requirements of the surgical operation, the retractor mounting bolt 13 is screwed into the retractor mounting screw hole. When the retractor mounting bolt 13 abuts against the auxiliary retractor 4, the auxiliary retractor 4 is clamped on the hole wall of the retractor mounting screw hole. The fixation is completed when the auxiliary retractor 4 does not fall off.
[0054] like Figure 1 As shown by the arrow, the assembled retractor fixer 1 is finally hung on the top of the fixer bracket 2 along the direction of the arrow. The fixer bracket 2 is erected above the surgical area to complete the arrangement of the suspension device of the embodiment of the present application.
[0055] The suspension device provided in the embodiment of the present application can fix the auxiliary hook 4 along the axial length of the auxiliary hook 4 through the hook fixer 1, eliminating the existing structure of setting a hook on the auxiliary hook, preventing the auxiliary hook 4 from being deformed due to pulling the bracket, resulting in the auxiliary hook being unable to lift the surgical area muscle group during surgery.
[0056] Embodiment 3
[0057] Based on the suspension device of the second embodiment, in order to specifically illustrate the remaining structures in the suspension device, the embodiment of the present application further provides a suspension device for a laparoscope hand-assisted retractor, comprising the retractor fixer 1 and the fixer bracket 2 shown in the first embodiment.
[0058] Further, such as Figure 2As shown, the body of the hook fixer 1 shown in the embodiment of the present application is a fixed plate body 10, one wide side of the fixed plate body 10 is bent along the central axis toward the other wide side to form a hook 11 for hanging. Exemplarily, the fixed plate body 10 is a bent rectangular metal plate, which is folded around its short axis, and its inner corner serves as the hook 11 hanging on the fixer bracket.
[0059] Furthermore, in order to firmly fix the hook fixer 1 on the fixer bracket 2, the hook fixer 1 further includes a fixer mounting bolt 15, and the fixing plate 10 is further provided with a fixer mounting hole 14.
[0060] Specifically, the hook receiving hole 12 and the fixer mounting hole 14 are respectively arranged near two wide sides of the fixing plate body 10 .
[0061] For example, Figure 2 As shown, the fixing device mounting hole 14 is arranged at the outer corner area of the fixing plate body 10, and the fixing device mounting hole 14 penetrates the fixing plate body 10 along the thickness direction of the fixing plate body 10, and the fixing device mounting bolt 15 is threadedly matched with the fixing device mounting hole 14. Preferably, the hook mounting bolt 13 and the fixing device mounting bolt 15 are butterfly bolts.
[0062] For the fixer bracket 2, in order to facilitate the adjustment of the position of the auxiliary hook 4, the fixer bracket 2 shown in the embodiment of the present application has a plurality of adjustable parts.
[0063] like Figure 4 As shown, the fixing bracket 2 shown in the embodiment of the present application includes a first support rod 20 and a second support rod 21 .
[0064] Further, such as Figure 5 As shown in the top view of the structure of the fixer bracket, the first support rod 20 is also provided with a hook hanging ring 204 and a fixer positioning groove 203.
[0065] Specifically, the fixture positioning grooves 203 are arranged in an array along the length direction of the first support rod 20. For example, in the embodiment of the present application, 20 fixture positioning grooves 203 are arranged on the top surface of the first support rod 20, with an interval of 5 mm.
[0066] In the embodiment of the present application, the hook fixer 1 is along Figure 1The hook is hooked into the hook ring 204 of the holder bracket 2 in the direction of the arrow shown. The position of the hook holder 1 is adjusted along the length direction of the first support rod 20, and then the holder mounting bolt 15 is screwed into the holder mounting hole 14 on the first support rod 20. The holder mounting bolt 15 abuts against one of the holder mounting holes 14 of the first support rod 20, thereby completing the position limitation of the hook holder 1.
[0067] In order to be able to adjust the placement angle of the first support rod 20 on the horizontal plane and at the same time allow the structure between the first support rod and the second support rod to be disassembled for disinfection and cleaning, the first support rod and the second support rod of the fixer bracket provided in the embodiment of the present application are movably connected.
[0068] Specifically, Figure 4 As shown, the first support rod 20 is provided with a hexagonal head 201 , and the second support rod 21 is provided with a hexagonal hole 202 , and the hexagonal head 201 of the first support rod 20 and the hexagonal hole 202 of the second support rod 21 are adapted in shape.
[0069] In the embodiment of the present application, the hexagonal head 201 is a protrusion perpendicular to the length direction of the first support rod 20. The cross section of the hexagonal head 201 is hexagonal.
[0070] In the embodiment of the present application, since the first support rod 20 is provided with a hexagonal head 201 and the second support rod 21 is provided with a hexagonal hole 202, when it is necessary to adjust the angle between the two rods, the first support rod 20 is pulled out, rotated around the hexagonal head 201 to the required angle position, and then the hexagonal head 201 is inserted into the hexagonal hole 202.
[0071] The existing movable connecting parts have complex structures and are prone to produce sanitary blind spots when used in the field of medical devices. However, the fixing bracket 2 of the suspension device provided in the embodiment of the present application has a simple structure. After the operation is completed, the fixing bracket can be disassembled for disinfection, and it is not easy to produce sanitary blind spots.
[0072] Regarding the device in the above embodiment, the specific manner in which each module performs operations has been described in detail in the embodiment of the method, and will not be elaborated again here.
[0073] The embodiments of the present application have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
