[0025] Example

[0026] The surgical incision traction device described in this embodiment is as follows: Figure 1 and Figure 3 As shown, it comprises a plurality of connecting plates 2, which are arranged in sequence from front to back, and the bottom of each connecting plate 2 is fixed with a retractor 1 for pulling the incision open. When the retractor 1 is specifically installed, the top of the retractor 1 is preferably fixed to the edge position on the left side of the bottom of the connecting plate 2; when in use, the retractor 1 is placed at the position of the incision, and then the incision can be pulled open by pulling the retractor 1, so that the surgical field of view is clearer and the surgery is convenient;

[0027] like Figure 1 As shown, the bottom of the retractor 1 is an arc-shaped structure, and the design of this structure can make the incision more stable when being pulled;

[0028] The connecting plate 2 is made of stainless steel, and the draw hook 1 is made of stainless steel. The material not only has good corrosion resistance, but is also strong and durable.

[0029] like Figure 1 and Figure 3 As shown, a limiting plate 3 is provided on the right side of the connecting plate 2, and a groove for the connecting plate 2 to be inserted is opened on the left side wall of the limiting plate 3 corresponding to each connecting plate 2. After the grooves are opened, they are preferably arranged at equal intervals front and back, so that the connecting plate 2 can be placed in the grooves on the limiting plate 3 at equal intervals front and back;

[0030] like Figure 1 and Figure 2As shown in the figure, a freely rotatable rotating rod is installed in each groove, a ratchet 6 is mounted on the rotating rod, a pawl 7 engaged with the ratchet 6 is arranged above the ratchet 6, and the pawl 7 is hinged to the top of the groove through a fixing block 10; when the rotating rod is installed, the rotating rod is placed horizontally front and back, and its front and rear ends are mounted on the front and rear side walls of the groove through bearings; blind holes are opened on the front and rear side walls of the groove, the outer ring of the bearing is fixed in the blind holes, and the front and rear ends of the rotating rod are fixed to the inner ring of the bearing, so the rotating rod can realize free rotation, because the ratchet 6 is mounted on the rotating rod, so the ratchet 6 can also realize free rotation; when the pawl 7 is installed, as shown in the figure, Figure 2 In the middle position, the upper end of the pawl 7 can be hinged on the left side wall of the fixed block 10 through a hinge seat; the hinge seat is a known product, which includes two front and rear fixed blocks, each of which is provided with a mounting hole that is connected to the front and rear, and a rotating shaft is installed on the front and rear sides of the pawl 7, and the rotating shaft is installed in the mounting hole through a bearing, the outer ring of the bearing is fixed in the mounting hole, and the rotating shaft is fixed to the inner ring of the bearing; thereby, the pawl 7 is hinged; when the fixed block 10 is installed, its top is fixed to the top of the groove, so when the fixed block 10 is installed in the groove, the pawl 7 is also limited in the groove;

[0031] like Figure 1 and Figure 2 As shown, a tension spring 11 is provided between the pawl 7 and the fixed block 10, one end of the tension spring 11 is fixed to the pawl 7, and the other end thereof is fixed to the fixed block 10; this section of the scheme as a whole constitutes an elastic component for pulling the pawl 7 to engage with the ratchet 6; by designing the tension spring 11, the pawl 7 can be pulled to the right, as shown in FIG. Figure 2 In the middle position, in the pulling state, the bottom of the pawl 7 is located in the ratchet teeth of the ratchet wheel 6, and the pawl 7 and the ratchet wheel 6 are in a bite state;

[0032] In a specific implementation process, there may be two tension springs 11 in the elastic component, so that the pawl 7 can be more stably engaged with the ratchet teeth of the ratchet wheel 6;

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, a pull rod 9 is provided on the pawl 7, one end of the pull rod 9 is hinged on the pawl 7, a through hole communicating with the inside of the groove is opened on the top of the limit plate 3, and the other end of the pull rod 9 passes through the through hole and is located above the limit plate 3; this section of the scheme as a whole constitutes a pulling assembly for pulling the pawl 7 away from the ratchet teeth of the ratchet wheel 6; one end of the pull rod 9 is Figure 2 The lower end of the middle tie rod 9, the other end of which is Figure 2The upper end of the middle pull rod 9 can also be hinged to the pawl 7 through the hinge seat when it is specifically hinged. The hinge method is consistent with the hinge method of the pawl 7, so it is not repeated here. When in use, the upper end of the pull rod 9 is pulled, so that the pawl 7 can be driven to move, so that the pawl 7 can be moved out from the ratchet teeth of the ratchet wheel 6, and the ratchet wheel 6 can rotate freely. When the pull rod 9 stops being pulled, the pawl 7 is re-engaged on the ratchet teeth of the ratchet wheel 6 under the action of the elastic component.

[0034] In a specific implementation process, the pull rod 9 in the pulling assembly can also be replaced by a rope, one end of the rope is tied to the pawl 7, and the other end of the rope passes through the through hole and is located above the limit plate 3. When in use, pulling the other end of the rope can also drive the pawl 7 to move, so that the pawl 7 can be pulled out from the ratchet teeth of the ratchet wheel 6;

[0035] like Figure 1 and Figure 2 As shown, a handle 8 is fixed on the top of the pull rod 9. The design of the handle 8 makes it easier to operate the pull rod 9 to move;

[0036] like Figure 1 and Figure 2 As shown, in the engaged state of the ratchet 6 and the pawl 7, the ratchet 6 is prevented from rotating clockwise; a plurality of slots meshing with the ratchet 6 are provided on the top of the connecting plate 2; because the connecting plate 2 is meshed with the ratchet 6, the right half of the connecting plate 2 is placed in the groove and inserted from the bottom of the ratchet 6. During the insertion process, the bottom of the connecting plate 2 fits with the bottom of the groove, and its top meshes with the ratchet 6. During the meshing process, the ratchet 6 rotates counterclockwise. Because the ratchet 6 and the pawl 7 are engaged, the ratchet 6 can only rotate counterclockwise, so the connecting plate 2 can smoothly enter the groove. When the connecting plate 2 needs to be taken out, the ratchet 6 needs to rotate clockwise, and the ratchet 6 cannot rotate clockwise at this time, so that the right half of the connecting plate 2 can be stuck between the ratchet 6 and the groove, thereby achieving the purpose of locking the connecting plate 2. When the connecting plate 2 is locked When the connecting plate 2 needs to be disassembled, it is only necessary to operate the pulling assembly to move the pawl 7 out of the ratchet 6. After the removal, the ratchet 6 can be rotated clockwise, and the connecting plate 2 can be moved out from between the ratchet 6 and the groove to achieve the purpose of disassembly; in this process, it is convenient to install and disassemble the connecting plate 2 and the retractor 1. At the same time, because a plurality of retractors 1 and connecting plates 2 are provided on the limiting plate 3 in the present design, when in use, a suitable number of retractors 1 and connecting plates 2 can be selected according to the size of the surgical incision and installed on the limiting plate 3, so as to facilitate pulling of incisions of different sizes; for example, when one retractor 1 is needed to pull the incision, a group of retractors 1 and connecting plate 2 are installed in the groove of the limiting plate 3, and when two retractors 1 are needed to pull the incision, two groups of retractors 1 and connecting plate 2 are installed in the groove of the limiting plate 3;

[0037] like Figure 1 and Figure 3 As shown, a handle 4 is horizontally fixed on the right side wall of the limiting plate 3. Figure 1 In the middle position, the left end of the handle 4 is fixed on the right side wall of the limiting plate 3; through the design of the handle 4, the handle 4 can drive the limiting plate 3, the retractor 1 and the connecting plate 2 to pull the surgical incision, which is more convenient to use;

[0038] like Figure 1 and Figure 3 As shown, the handle 4 is covered with an anti-slip cover 5. The design of the anti-slip cover 5 allows the handle 4 to be operated more stably.

[0039] The length of the handle 4 is 10 cm-15 cm. In the specific implementation process, the length of the handle 4 can be selected to be 10 cm, 11 cm, 12 cm, 13 cm, 14 cm, 15 cm or between 10 cm and 15 cm. The design within this range facilitates the operation of the handle 4 to drive the retractor 1 and the connecting plate 2 to pull. If the length of the handle 4 is less than 10 cm, it may result in the inability to stably drive the retractor 1 and the connecting plate 2 to pull the incision during the operation of the handle 4. If the length of the handle 4 is greater than 15 cm, it will lead to a waste of resources and increase production costs.

[0040] The thickness of the connecting plate 2 is 2-3mm, and the thickness of the hook 1 is 2-3mm; in the specific implementation process, the thickness of the connecting plate 2 and the hook 1 can be selected from 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, 3mm or between 2mm and 3mm; through the design within this range, the connecting plate 2 and the hook 1 can stably pull the incision. If the thickness of the hook 1 and the connecting plate 2 is less than 2mm, it may cause the thickness to be too thin and easy to break; if the thickness of the hook 1 and the connecting plate 2 is greater than 3mm, it will lead to waste of resources and increase production costs;

[0041] During specific use: first, according to the size of the surgical incision, select a suitable number of retractors 1 and connecting plates 2 and insert them into the groove of the limiting plate 3. During the insertion process, with the cooperation of the ratchet 6 and the pawl 7, the connecting plate 2 can be directly fixed in the groove, and the rear operating handle 4 can drive the retractors 1 and the connecting plate 2 to pull the surgical incision; after use, use the pulling assembly, and the connecting plate 2 can be taken out of the groove, thereby achieving the purpose of disassembly and facilitating subsequent cleaning and disinfection; therefore, in this use process, according to the size of the incision, the corresponding number of retractors 1 and connecting plates 2 can be selected and installed on the limiting plate 3, so that it can be used for surgical incisions of different sizes.
