[0041] Example

[0042] like Figure 1-Figure 5 As shown, an intraoperative wound fixation device includes a first fixing mechanism 100 connected to an operating table and a second fixing mechanism 200 connected to the first fixing mechanism 100; the second fixing mechanism 200 includes a fixing ring 210, and the fixing ring 210 is attached around the wound; a plurality of grabbing hooks 240 are connected to the fixing ring 210, and the plurality of grabbing hooks 240 can slide along the connecting line between the center and the outer edge of the fixing ring 210; the plurality of grabbing hooks 240 penetrate into the wound and slide along the center to the outer edge of the fixing ring 210 to fix the wound.

[0043] The working mechanism of the intraoperative wound fixation device provided in this embodiment is as follows:

[0044] When in use, first connect the first fixing mechanism 100 to the operating table, then control the fixing ring 210 to move to the wound, so that the wound is in the middle of the fixing ring 210, move the grab hook 240 on the fixing ring 210 into the wound, and control multiple grab hooks 240 to move away from the center of the fixing ring 210. At this time, the grab hook 240 pulls the wound to expand, thereby fixing the size of the wound. During use, select a suitable number of grab hooks 240 according to the size of the wound, so that the wound can be stably fixed during the operation.

[0045] Regarding how the Grappling Hook 240 moves, specifically:

[0046] The fixing ring 210 is connected to an elastic connecting tube 220 , and a sliding seat 230 is connected to the side wall of the elastic connecting tube 220 ; the grab hook 240 is connected to a rack 250 , and the rack 250 is inserted into the sliding seat 230 ; the sliding seat 230 is rotatably connected to a gear 260 meshing with the rack 250 .

[0047] The elastic connecting tube 220 can be deformed, and the elastic connecting tube 220 can rotate and slide relative to the fixed ring, so that the position and angle of the grab hook 240 can be adjusted. By rotating the gear 260, the rack 250 can be driven to slide relative to the slide seat 230, so that the grab hook 240 can move after penetrating into the wound and pull the wound open for fixing.

[0048] Regarding how to control the rotation of the gear 260, specifically:

[0049] A rectangular frame 270 is vertically slidably connected to the slide 230, and a V-shaped locking block 280 is connected to the lower surface of the rectangular frame 270; the axis of the gear 260 is inserted into the V-groove of the V-shaped locking block 280; when the rectangular frame 270 moves downward, the V-shaped locking block 280 moves away from the axis of the gear 260, thereby unlocking the gear 260; when the rectangular frame 270 moves upward, the V-shaped locking block 280 approaches the axis of the gear 260, thereby locking the gear 260.

[0050] After the grab hook 240 moves to the appropriate position, the rectangular frame 270 moves up and drives the V-shaped locking block 280 to contact the shaft of the gear 260. The contact portion between the V-shaped locking block 280 and the gear 260 is provided with anti-slip grooves, so that after the two contact, the gear 260 can be locked so that the gear 260 no longer rotates, thereby fixing the position of the grab hook 240. When it is necessary to control the rotation of the gear 260, the rectangular frame 270 is manually pressed to move the rectangular frame 270 downward. At this time, the V-shaped locking block 280 does not contact the shaft of the gear 260, so that the finger can drive the gear 260 to rotate through the middle of the rectangular frame 270 to control the position movement of the grab hook 240.

[0051] Among the optional methods of this embodiment, the more preferred ones are:

[0052] The four corners of the rectangular frame 270 are connected to vertical rods 290 , which slide axially on the slide seat 230 ; the vertical rods 290 are connected to springs 291 , and the two ends of the springs 291 are respectively connected to the rectangular frame 270 and the slide seat 230 .

[0053] The setting of the vertical rod 290 allows the rectangular frame 270 to move down until the gear 260 passes through the hollow of the rectangular frame 270 and moves up to a certain height above the rectangular frame 270 and the V-shaped locking block 280 is away from the axis of the gear 260. Then, the vertical rod 290 slides to the lower limit of its stroke, thereby preventing the rectangular frame 270 from contacting the gear 260 and affecting the rotation of the gear 260. In addition, when pressure is no longer applied to the rectangular frame 270, the spring 291 deforms and recovers, causing the rectangular frame 270 to move up, reset, and lock the gear 260.

[0054] Regarding the structure of the first fixing mechanism 100, specifically:

[0055] The first fixing mechanism 100 includes two storage rollers 150, and the two storage rollers 150 are respectively fixed on both sides of the operating table; a fixing belt 151 is connected between the two storage rollers 150, and a fixing ring 210 is connected to the middle of the fixing belt 151; when the two storage rollers 150 reel in the fixing belt 151 synchronously or separately, the fixing ring 210 can be attached to the four sides of the wound.

[0056] When the storage roller 150 rotates, it can reel in the fixing belt 151, so that the fixing belt 151 can be close to the patient's body. As the fixing belt 151 is tightened, the fixing belt 151 can eventually be attached to the patient's body. By controlling the rotation degree of the two storage rollers 150 respectively, the position of the fixing ring 210 can be controlled, thereby ensuring that the fixing ring 210 can be located around the wound.

[0057] Among the optional methods of this embodiment, the more preferred ones are:

[0058] The first fixing mechanism 100 also includes two fixing seats 110, and the two storage rollers 150 are respectively fixedly rotated on the fixing seats 110; the fixing seats 110 are connected with an upper splint 120 and a lower splint 130, the upper splint 120 is fixed to the fixing seat 110, and the lower splint 130 slides on the fixing seat 110, and the upper splint 120 and the lower splint 130 are clamped on the operating bed; the upper splint 120 and the lower splint 130 are commonly connected with a locking screw 140, the locking screw 140 is rotatably connected to the upper splint 120, and the locking screw 140 does not slide axially relative to the upper splint 120, and the locking screw 140 is threadedly connected to the lower splint 130.

[0059] Move the two fixing seats 110 to the two sides of the operating bed respectively, so that the bed board of the operating bed is between the upper clamping plate 120 and the lower clamping plate 130, and tighten the locking screw 140 to clamp the upper clamping plate 120 and the lower clamping plate 130 on the operating bed, thereby completing the fixation of the first fixing mechanism 100.

[0060] Among the optional methods of this embodiment, the more preferred ones are:

[0061] A ratchet 170 is connected to the end of the storage roller 150 , and a pawl 180 that cooperates with the ratchet 170 is connected to the fixing seat 110 .

[0062] The cooperation between the ratchet 170 and the pawl 180 allows the storage roller 150 to rotate in the direction of storing the fixing belt 151, thereby ensuring that the fixing belt 151 can be fixed tightly on the patient's body. If it is necessary to control the storage roller 150 to release the fixing belt 151, pull the slide bar 190 to make the pawl 180 move away from the ratchet 170. At this time, the storage roller 150 can rotate in both directions, thereby completing the release of the fixing belt 151. The return spring 191 sleeved on the slide bar 190 can provide thrust for the upward movement of the pawl 180, thereby ensuring the stable contact between the pawl 180 and the ratchet 170 when the storage roller 150 stores the fixing belt 151.

[0063] Among the optional methods of this embodiment, the more preferred ones are:

[0064] One end of the storage roller 150 away from the ratchet wheel 170 is connected to a handle 160 .

[0065] The provision of the handle 160 allows the rotation of the storage roller 150 to be easily controlled manually.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of each embodiment of the utility model.
