[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] The purpose of this invention is to provide a compression hemostat after lower extremity varicose vein stripping surgery to solve the problems existing in the prior art. The length is adjustable and it is suitable for different leg shapes of patients.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1-6 As shown, this embodiment provides a compression hemostat after lower extremity varicose vein stripping surgery, including a length-adjustable plate assembly 1, a first pressing rod 2, and a second pressing rod 3. The length-adjustable plate assembly 1 has two sets, which are arranged parallel to each other. The lower ends of the first pressing rod 2 and the second pressing rod 3 are slidably connected to the two sets of length-adjustable plate assemblies 1, respectively. The upper end of the first pressing rod 2 is hinged to the upper end of the second pressing rod 3. By adjusting the angle of the upper ends of the first pressing rod 2 and the second pressing rod 3, the pressure exerted by the first pressing rod 2 and the second pressing rod 3 on the two sets of length-adjustable plate assemblies 1 can be changed.

[0032] The length-adjustable plate assembly 1 includes a set of fixed plates 102 and two sliding blocks 103. The set of fixed plates 102 includes two fixed plates 102 and one fixed block 101. The two fixed plates 102 are arranged in parallel and both fixed plates 102 pass through the fixed block 101, which is located in the middle of the fixed plates 102. The two sliding blocks 103 are slidably connected to the fixed plates 102 and are located on both sides of the fixed block 101.

[0033] In actual use, the patient's lower limbs are clamped between two adjustable length plate groups 1. The position of the sliding block 103 on the fixed plate 102 is adjusted to suit the leg shape of different patients. Then, medical staff only need to adjust the first pressing rod 2 and the second pressing rod 3 up and down to adjust the pressure of the two adjustable length plate groups 1 on the patient's lower limbs.

[0034] In this embodiment, as Figures 2-3 As shown, both the fixed block 101 and the sliding block 103 have horizontal grooves on their outer surfaces. The lower ends of the first pressing rod 2 and the second pressing rod 3 are each provided with cylindrical sliders 4. The sliders 4 extend from one end of the groove and slide within it. Through the sliding engagement between the sliders 4 and the groove, the specific positions of the first pressing rod 2 and the second pressing rod 3 can be adjusted, thereby applying pressure to different positions of the patient's lower limbs.

[0035] In this embodiment, the lower ends of the first pressing rod 2 and the second pressing rod 3 are both provided with threaded holes, and a threaded post is fixed on the slider 4. The outer surface of the threaded post is provided with external threads, so that the threaded post can be threaded into the threaded hole, thereby realizing the fixation between the first pressing rod 2 and the second pressing rod 3 and the corresponding slider 4.

[0036] In this embodiment, both the fixed block 101 and the sliding block 103 are provided with two sliding slots. Each fixed plate 102 is slidably disposed in the corresponding sliding slot, thereby limiting the fixed block 101 and the sliding block 103 in the vertical direction (i.e., the direction perpendicular to the length direction of the fixed plate 102). The sliding slot is located between the two sliding slots.

[0037] In this embodiment, as Figure 1 and Figure 3 As shown, the upper end of the sliding block 103 has multiple positioning holes spaced apart, and each end of the fixing plate 102 is provided with a positioning device 5. Specifically, each end of the fixing plate 102 is provided with a mounting groove, and each mounting groove contains a positioning device 5, which can extend into the positioning hole. When the sliding block 103 slides to the expected position, the positioning device 5 will extend into the corresponding positioning hole to position the sliding block 103.

[0038] In this embodiment, as Figure 6As shown, the positioning device 5 includes a spring plate, and the upper end of the spring plate is provided with a positioning protrusion. Of course, those skilled in the art can also replace it with other positioning structures, such as the existing combination of spring and steel ball, that is, the spring is fixed in the mounting groove, the steel ball is installed on one end of the spring, and the positioning function of the sliding block 103 is achieved by the steel ball extending into the positioning hole.

[0039] In this embodiment, as Figure 6 As shown, the spring sheet has a C-shaped structure, specifically including an upper horizontal sheet, a vertical sheet, and a lower horizontal sheet. The upper and lower horizontal sheets are fixed to the upper and lower ends of the vertical sheet, respectively, and the positioning protrusion is fixed to the upper end of the upper horizontal sheet. When the sliding block 103 needs to be moved, the medical staff presses down on the positioning protrusion, reducing the distance between the upper and lower horizontal sheets. When the expected position is reached, the positioning protrusion returns to its original position under the return force of the spring sheet and extends into the corresponding positioning hole, thereby limiting the sliding block 103.

[0040] In this embodiment, as Figures 4-5 As shown, both the first pressing rod 2 and the second pressing rod 3 are L-shaped structures.

[0041] In this embodiment, as Figure 1 , Figures 4-5 As shown, the upper end of the first pressing rod 2 is hinged to the corner of the second pressing rod 3 by a pin, thereby realizing the rotational connection between the two. The purpose of this arrangement is that the pressure of the first pressing rod 2 and the second pressing rod 3 on the two adjustable length plate groups 1 can be adjusted simply by pushing the first pressing rod 2 or the second pressing rod 3 up and down.

[0042] In this embodiment, as Figure 1 , Figures 4-5 As shown, the first pressing rod 2 is provided with a first rack 201, and the second pressing rod 3 is provided with a second rack 301. The first rack 201 and the second rack 301 mesh. Since the first pressing rod 2 and the second pressing rod 3 are hinged, the included angle between the first pressing rod 2 and the second pressing rod 3 will frequently change. In order to ensure that the first pressing rod 2 and the second pressing rod 3 maintain a certain included angle, the meshing of the first rack 201 and the second rack 301 can limit the relative position of the first pressing rod 2 and the second pressing rod 3. Furthermore, as the relative included angle of the first pressing rod 2 and the second pressing rod 3 changes, the length of the meshing portion of the first rack 201 and the second rack 301 also changes accordingly.

[0043] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
