Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a tissue cutting edge dyeing device. Background Art

[0002] Cervical conization is a gynecological surgery to remove the cervix, which means cutting off a part of the cervical tissue from the outside to the inside in a cone shape. On the one hand, it is for pathological examination and diagnosis of cervical lesions; on the other hand, it is also a treatment method for removing lesions.

[0003] The existing tissue after cervical conization is roughly vertebral and has a conical cutting edge. In order to facilitate subsequent pathological detection, the cutting edge needs to be stained. The existing staining method usually uses a brush or a writing brush dipped in a dye, and then manually applies it to the conical cutting edge of the cone-cut tissue. Moreover, the application often needs to be done in multiple times, and the staining is slow, and the staining is often uneven and incomplete, and the operation is cumbersome. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0022] like Figures 1 to 3 As shown, a tissue cutting edge staining device of the present invention comprises a base 1, a pressing and rotating mechanism 2, a staining tank body 3 and a staining sponge 4.

[0023] The base 1 is provided with a pressing and rotating mechanism 2, on which a dyeing tank body 3 is fixed, wherein the dyeing tank body 3 has a dyeing tank 31 with a top opening, and a dyeing sponge 4 is placed and circumferentially limited inside the dyeing tank 31, and the dyeing sponge 4 absorbs the dyeing liquid;

[0024] The pressing and rotating mechanism 2 comprises a rotating body 21 and a fixed shaft 22 which are mutually sleeved up and down. The lower end of the fixed shaft 22 is connected and fixed to the base 1, and the upper end of the rotating body 21 is connected and fixed to the dyeing tank 3.

[0025] The upper end of the fixed shaft 22 movably extends into the rotating groove 211 set at the lower end of the rotating body 21, and a spring 23 is installed between the upper end of the fixed shaft 22 and the top of the rotating groove 211; the outer wall of the fixed shaft 22 is concave with two centrally symmetrical spiral grooves 241, and the lower end of any spiral groove 241 is connected to the upper end of the other spiral groove 241 through an axial straight groove 242; the inner wall of the lower end of the rotating body 21 is provided with a protruding slider 25, which can be slidably located in the spiral groove 241 or the straight groove 242.

[0026] In this way, the vertebral tissue A cut out from the cervical cone is fixed, and the handle 5 can be inserted into the middle of the plane of the cone to fix it, so that the cutting edge B of the cone surface is outward, and then the dyeing tank 31 of the dyeing device is placed upward on a flat table or tabletop, and the base 1 is fixed to prevent rotation or movement, and a dyeing sponge 4 adsorbed with dyeing liquid is inserted into the dyeing tank 31. The vertebral tissue A is held by hand so that the cutting edge B of the cone surface extends downward into the dyeing tank 31 and contacts with the dyeing sponge 4, and then the vertebral tissue A is pressed downward. The vertebral tissue A can compress the dyeing sponge 4 and the dyeing tank body 3, and the dyeing tank body 3 connected to the pressing and rotating mechanism 2 will drive the dyeing tank body 3 and the dyeing sponge 4 to rotate together after being axially compressed, so as to ensure that the dyeing of the cutting edge B is more uniform. After pressing and releasing twice, the dyeing tank body 3 and the dyeing sponge 4 can rotate one circle, so that the cutting edge B of the cone surface is completely and evenly dyed.

[0027] The specific pressing and rotating principle is as follows: in the initial state, the slider 25 of the rotating body 21 is located at the upper end of the spiral groove 241. When the rotating body 21 is pressed, the fixed shaft 22 connected to the base 1 does not move, and the slider 25 of the rotating body 21 will make a circumferential downward spiral rotation along the spiral groove 241, while pressing the spring 23 in the rotating groove 211. When the slider 25 rotates to the lower end of the spiral groove 241, the dyeing sponge 4, the dyeing tank body 3 and the rotating body 21 rotate 180 degrees synchronously. After the pressing force is released, the spring 23 is reset, so that the slider 25 slides along the straight groove 242 back to the upper end of the other spiral groove 241, thereby lifting the rotating body 21, the dyeing sponge 4, the dyeing tank body 3 and the vertebral tissue A, and then the vertebral tissue A is pressed down again, so that the slider 25 continues to make a circumferential downward spiral rotation along the other spiral groove 241, so that the dyeing sponge 4, the dyeing tank body 3 and the rotating body 21 can be synchronously rotated 180° again. Finally, after two presses and releases, the dyeing sponge 4 can rotate one circle around the conical cutting edge B to achieve uniform dyeing.

[0028] See also Figure 4 In this embodiment, a lower step 243 of the straight groove 242 is formed between the bottom of the straight groove 242 and the lower end of the spiral groove 241; a lower upper step 244 of the spiral groove 241 is formed between the top of the straight groove 242 and the upper end of the spiral groove 241.

[0029] See also Figure 3 The inner wall of the lower end of the rotating body 21 has a slider through hole 212 radially connected to the outside world; the slider 25 is inserted into the slider through hole 212, the inner end of the slider 25 protrudes from the inner wall of the lower end of the rotating body 21, and the outer end of the slider 25 is limited and resisted by a spring piece 26 clamped on the outer opening of the slider through hole 212.

[0030] Therefore, when the slider 25 is located at the upper end of the spiral groove 241, it is limited by the upper step 244 and the spring 26. When the rotating body 21 is pressed, the slider 25 can only slide along the spiral groove 241. When the spring 23 is reset, it is also limited by the lower step 243. The rotating body 21 can only slide upward along the straight groove 242.

[0031] In order to facilitate production and manufacturing, the upper end of the fixed shaft 22 of this embodiment is provided with two separate arc-shaped sheets 24, which are cylindrical when the two arc-shaped sheets 24 are embraced. The upper part of the fixed shaft 22 is provided with a connecting shaft 221 with a reduced diameter for the two arc-shaped sheets 24 to be embraced and fixed; the arc-shaped sheet 24 is connected to the fixed shaft 22 as a whole, and can be adhered and fixed as a whole; the spiral groove 241 and the straight groove 242 are both located on the outer wall of the arc-shaped sheet 24.

[0032] like Figure 3 As shown, the side wall of the dyeing tank body 3 is provided with at least two fixing ridges 32 for fixing the dyeing sponge 4 so that the dyeing sponge 4 can rotate along with the dyeing tank body 3 and the dyeing sponge 4 can be replaced at the same time.

[0033] Furthermore, the height of the dyeing sponge 4 is lower than the depth of the dyeing tank 3, which can prevent the dyeing liquid from seeping out.
