Description

Technical Field

[0001] The utility model relates to the technical field of pathological tissue processing, in particular to a prostate tissue pathological sampling and cutting device. Background Art

[0002] The prostate is an unpaired, solid gland in the male reproductive system, located between the bladder and the urogenital diaphragm, surrounding the base of the urethra. Its shape and size are similar to a slightly flattened chestnut. In the diagnosis and treatment of prostate cancer, pathological diagnosis is the final confirmation of prostate cancer, so prostate cancer specimens must be collected and sliced. Currently, surgeons typically use a scalpel to slowly slice open the tissue. However, due to its large size and round shape, it can easily roll and cut into hands, resulting in uneven thickness. Too thick a scalpel makes dehydration difficult, making it difficult to identify the lesion, while too thin a scalpel results in a larger number of wax blocks, increasing the workload.

[0003] After searching, application number 202410654486.4 disclosed a breast cancer postoperative pathology specimen cutting and preprocessing device, which includes a bracket, a water collection tank provided at the upper end of the bracket, a water filter plate provided at the upper end of the water collection tank, and a cover body with a front opening provided at the upper end of the water collection tank. The device can automatically and evenly cut breast specimens into book-like sections, eliminating the need for doctors to cut them piece by piece, effectively reducing the doctor's labor intensity.

[0004] However, the above method still has the following defects in actual use: the device is large in size, the cutting steps are cumbersome, it is difficult to clean and disinfect, and is not suitable for daily work. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] See also Figures 1 to 4 In the embodiment of the present invention, a prostate tissue pathology sampling and cutting device includes a base 1 and a mounting frame 3 rotatably arranged above the base 1. A cutting seat 2 is engaged with the top of the base 1. A positioning cavity is provided in the middle of the cutting seat 2 for placing prostate tissue to prevent its position from moving. A plurality of cutting grooves 201 are provided on the surface of the cutting seat 2 so that the cutting blade 3015 can enter the interior of the cutting groove 201 during cutting without interfering with the cutting of the prostate tissue and without causing damage to the cutting blade 3015. A plurality of knife seats 304 are provided inside the mounting frame 3 so as to slide and adjust the adjacent knife seats. The distance between the seats 304 can be adjusted to cut thin slices of different thicknesses, and a positioning pin 308 is provided on one side of the mounting frame 3 to limit the position of the knife seat 304. After the position of the knife seat 304 is adjusted, its position is limited. A mounting slot 309 is provided at the bottom of the knife seat 304, and a cutting blade 3015 is installed inside the mounting slot 309. Limiting seats 3011 are slidingly provided on both sides of the bottom of the knife seat 304 to limit the position of the cutting blade 3015, so that the cutting blade 3015 can be quickly loaded and unloaded, and the position of the installed cutting blade 3015 is limited by the limiting seat 3011.

[0021] In this embodiment, preferably, a support leg 101 is fixedly provided at the bottom end of the base 1, and an anti-slip pad is fixedly provided at the bottom end of the support leg 101 to provide stable support for the base 1 and to achieve an anti-slip effect;

The double handles are convenient for the operator to control the vertical downward pressure with both hands, so that the slices can be cut more quickly.

[0023] In this embodiment, preferably, a rotation groove 102 is provided at the top of the base 1, and a rotation rod 301 that rotates with the rotation groove 102 is fixedly provided on one side of the mounting frame 3 close to the rotation groove 102, and a limit frame 302 is provided at the top of the base 1 to limit the position of the rotation rod 301, and the middle part of the limit frame 302 is set to an arc shape corresponding to the rotation rod 301, and the two sides of the limit frame 302 are provided with folded edges and are connected to the base 1 by screws;

[0024] In this embodiment, preferably, a sliding groove 303 is provided on the inner wall of the side of the mounting frame 3 close to the rotating rod 301, and a sliding seat 305 is provided on the end of the knife holder 304 close to the rotating rod 301, which is slidably engaged with the sliding groove 303. The sliding engagement between the sliding groove 303 and the sliding seat 305 guides and limits the movement of the knife holder 304.

[0025] In this embodiment, preferably, a positioning hole 306 is provided at one end of the knife holder 304 away from the rotating rod 301, and a plurality of groups of mounting holes 307 are provided on one side of the mounting frame 3 away from the rotating rod 301. Each group of mounting holes 307 has a plurality of mounting holes, and the distance between adjacent mounting holes 307 is 0.5 mm, which can cut sheets of different thicknesses. The corresponding mounting holes 307 are connected to the positioning holes 306 by positioning pins 308, which limit the position of the knife holder 304 and can adjust the distance between adjacent knife holders 304.

[0026] In this embodiment, preferably, both ends of the bottom of the knife seat 304 are provided with a second slide groove 3010, and the top of the limit seat 3011 is fixed with a second slide seat 3013 that slides with the second slide groove 3010, and the sliding cooperation between the second slide seat 3013 and the second slide groove 3010 guides the movement of the limit seat 3011. A limiting spring 3014 is provided between the second slide seat 3013 and the inner side of the second slide groove 3010, so that the limit seat 3011 can always be attached to the side of the cutting blade 3015 to limit its position, and a limiting groove 3012 is provided on the side of the slide seat 3013 close to the cutting blade 3015, so that the limiting groove 3012 is elastically engaged with the side of the cutting blade 3015 to further limit the position of the cutting blade 3015.

[0027] During use, the prostate tissue to be cut is first placed in the positioning cavity in the middle of the cutting seat 2 to fix the prostate tissue. Then, the staff holds the pressing handle 3016 and presses the mounting frame 3 downward vertically, and uses the cutting blade 3015 to quickly cut the prostate tissue into slices of uniform thickness.

[0028] When the distance between adjacent cutting blades 3015 needs to be adjusted, the positioning pin 308 is removed, and the knife holder 304 is slid to the corresponding position, and the positioning pin 308 is inserted into the corresponding mounting hole 307 and positioning hole 306 again to define the position of the knife holder 304;

[0029] When the cutting blade 3015 needs to be replaced, the limiting seat 3011 is moved to both sides to release the limit on the position of the cutting blade 3015, and then the cutting blade 3015 is pulled out from the mounting slot 309 of the blade holder 304 and replaced with a new cutting blade 3015;

[0030] Regularly dismantling the base 1, cutting seat 2 and mounting frame 3 for cleaning and disinfection will facilitate subsequent cutting work.

[0031] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent application are included in the scope of the present invention patent application.
