Description

Technical Field

[0001] The utility model is applicable to the technical field of medical equipment, and particularly relates to a surgical incision expansion device. Background Art

[0002] Currently, when performing surgery for diseases of the internal abdominal organs, it is necessary to use a scalpel to make an opening in the patient's abdomen in advance. After the opening, in order to prevent the incision from closing under the action of the muscles and affecting the normal operation of medical staff, a corresponding incision expander is often used to expand the incision for auxiliary treatment.

[0003] However, the expansion mechanism used in the current surgical incision expansion auxiliary treatment is often pulled by medical staff from both sides of the incision to expand it. In this process, not only the pulling force on both sides is different, but also the expansion angles produced are different, which can easily lead to insufficient expansion distance and affect the quality of surgery of medical staff. Therefore, we propose a surgical incision expansion device. Utility Model Content

[0004] The main purpose of the utility model is to provide a surgical incision expansion device, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A surgical incision expansion device comprises a mounting block, both ends of the side surface of the mounting block are fixedly mounted with connecting plates, and the number of connecting plates is four groups, and an I-shaped rod is rotatably mounted through the ends of each two groups of connecting plates away from the mounting block;

[0007] A support plate is fixedly sleeved on the middle end surface of each I-shaped rod, an adjusting bolt is screwed through the middle end of the mounting block, a transmission plate is rotatably mounted on the side of the adjusting bolt through a bearing, and both sides of the transmission plate away from the mounting block are hinged with transmission rods through a rotating shaft;

[0008] A connecting block is fixedly mounted on the side surface of each of the support plates, and one end of the transmission rod away from the mounting block is hinged to the outer side of the connecting block through a rotating shaft hinge, and the transmission plate and the transmission rod are movably located between the two groups of support plate sides.

[0009] By adopting the above technical solution, through the transmission conversion action of the transmission plate and the transmission rod, the two groups of expansion plates can be synchronously rotated inward or outward with the I-shaped rod as the center to perform expansion processing on both sides of the incision, thereby providing the same expansion force to both sides of the surgical incision, reducing the number of operating steps required for medical staff to expand the incision, and facilitating the adjustment of the expansion distance to improve the quality of the operation.

[0010] As an optional solution of the technical solution of the present application, a fitting frame is fixedly mounted on the outer surface of one end of each of the support plates away from the mounting block.

[0011] By adopting the above technical solution, the skin on both sides of the incision can be conveniently placed inside the fitting frame through the structural function for subsequent expansion treatment.

[0012] As an optional solution of the technical solution of the present application, a magic adhesive pad is fixedly bonded to the bottom surface of the mounting block, and a removable anti-slip pad is bonded to the bottom surface of the magic adhesive pad.

[0013] By adopting the above technical solution, the placement stability of the mounting block on the patient's skin surface is improved through the structural effects of the Velcro pad and the anti-slip pad, while the anti-slip pad in contact with the patient's skin can be easily replaced to avoid infection of the patient by miscellaneous bacteria.

[0014] As an optional solution of the technical solution of the present application, a rotating disk is fixedly sleeved on the surface of one side of the adjusting bolt away from the support plate.

[0015] By adopting the above technical solution, the adjusting bolt can be conveniently driven to be screwed by the structural function of the rotating disk.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. A surgical incision distraction device according to the technical solution of the present application, by installing a transmission plate on the side of an adjusting bolt, and connecting the two ends of a transmission rod to the transmission plate and the distraction plate through a rotating shaft, combined with the transmission conversion effect of the transmission rod, after the adjusting bolt is turned to drive the transmission plate to move horizontally between the two groups of distraction plates synchronously, the horizontal movement force of the transmission plate is converted into a push-pull force on the distraction plate, and then the two groups of distraction plates can be synchronously rotated inward or outward with the I-shaped rod as the center to push and distract the two sides of the incision, thereby providing a distraction force with the same distraction force to the two sides of the surgical incision synchronously, reducing the number of operating steps required for medical staff to adjust the incision distraction, while facilitating the adjustment of the distraction distance to improve the quality of the operation.

[0018] 2. A surgical incision expansion device according to the technical solution of the present application is provided with a corresponding Velcro pad at the bottom of the mounting block. Combined with the detachable effect of the Velcro pad on the anti-slip pad, the placement stability of the mounting block on the patient's skin surface is improved, while the anti-slip pad in contact with the patient's skin can be easily replaced to avoid infection of the patient by miscellaneous bacteria.

[0023] like Figure 1-3 As shown, the utility model provides a technical solution: a surgical incision expansion device, a magic adhesive pad 3 is fixedly bonded to the bottom surface of the mounting block 1, and a removable anti-skid pad 31 is bonded to the bottom surface of the magic adhesive pad 3.

[0024] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), connecting plates 11 are fixedly installed on the surfaces of both ends of the side of the mounting block 1, and the number of connecting plates 11 is four groups, and an I-shaped rod 12 is rotatably installed through each two groups of connecting plates at one end away from the mounting block 1, and a support plate 13 is fixedly sleeved on the middle end surface of each I-shaped rod 12.

[0025] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a fitting frame 24 is fixedly mounted on the outer surface of one end of each opening plate 13 away from the mounting block 1, and the side of the fitting frame 24 away from the opening plate 13 is open.

[0026] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a rotating disk 4 is fixedly sleeved on a side surface of the adjusting bolt 2 away from the expansion plate 13.
