[0005] As a further preferred solution, the left side and the right side of the trough are both arranged to be inclined to prevent the diseased body from rubbing against them.

[0006] As a further preferred embodiment, it also includes a sliding block, an elastic block and a blocking bar; two sliding grooves are respectively opened on the front and rear sides of the shell; a sliding block is slidably connected in each sliding groove; a number of elastic blocks are fixedly connected to each sliding groove at equal distances; a blocking bar is fixedly connected between the two front sliding blocks; another blocking bar is fixedly connected between the two rear sliding blocks, and the blocking bar is supported by the elastic block.

[0007] As a further preferred solution, the cross-section of the blocking strip is elliptical, which is convenient for medical staff to press.

[0008] As a further preferred solution, the facing sides of the two blocking strips are both provided with roughness to increase the friction with the splicing film, so as to facilitate the blocking of the splicing film.

[0009] As a further preferred solution, each blocking strip has a ventilation groove 1 in it; each blocking strip has a plurality of ventilation grooves 2 in it; and all ventilation grooves 2 are connected to ventilation groove 1.

[0010] Compared with the prior art, the utility model has the following advantages: the utility model provides a connecting film to receive the diseased body, so that all the diseased bodies in the same diseased area can be removed together, instead of the prior art in which medical staff use tweezers and other objects to clamp the diseased body, thereby avoiding the diseased body from remaining and mixing with all the diseased bodies in the next diseased area, affecting the detection and analysis of the diseased body; in addition, the second layer of the connecting film is blocked by a blocking strip to prevent the second layer of the connecting film from being lifted up by the top layer of the connecting film.

[0016] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Example

[0018] A minimally invasive incision device for breast biopsy, such as Figure 1-4 As shown, it includes a housing 1, a needle tube 2 and an electric peeling tube 3; the needle tube 2 is fixedly connected to the left part of the housing 1; the electric peeling tube 3 is connected inside the housing 1; the needle tube 2 and the electric peeling tube 3 cooperate with each other;

[0019] The housing 1 is provided with a material receiving film 4; a material trough 1a is provided on the housing 1; and a plurality of material receiving films 4 are placed in the material trough 1a.

[0020] The left side and the right side of the trough 1a are arranged to be inclined to prevent the diseased body from rubbing against them.

[0021] It also includes a sliding block 5, an elastic block 6 and a blocking bar 7; two sliding grooves 1b are respectively opened on the front and rear sides of the shell 1; a sliding block 5 is slidably connected in each sliding groove 1b; a number of elastic blocks 6 are fixedly connected to each sliding groove 1b at equal intervals; a blocking bar 7 is fixedly connected between the two front sliding blocks 5; another blocking bar 7 is fixedly connected between the two rear sliding blocks 5, and the blocking bar 7 is supported by the elastic block 6.

[0022] The blocking strip 7 has an elliptical cross section, which is convenient for medical staff to press.

[0023] The facing sides of the two blocking strips 7 are both provided with roughness, so as to increase the friction with the splicing film 4 and facilitate the blocking of the splicing film 4 .

[0024] Each blocking bar 7 has a ventilation groove 1 7a formed therein; each blocking bar 7 has a plurality of ventilation grooves 2 7b formed therein; and all ventilation grooves 2 7b are connected to ventilation groove 1 7a.

[0025] Before using the device, the medical staff first stacks a number of splicing films 4 in the material slot 1a. The upper layers of the splicing films 4 have shorter lengths, so that the sides of the splicing films 4 are stepped. Figure 3 When the needle 2 is pulled out of the patient's chest, the uppermost layer of the material film 4 is pulled out, and the uppermost layer of the material film 4 is pulled out. When the needle 2 is pulled out ...

[0026] When the top layer of splicing film 4 is extracted, the films may sometimes stick to each other, causing the second layer of splicing film 4 to be lifted up by the top layer of splicing film 4. Therefore, a blocking strip 7 is provided, which is located below the top layer of splicing film 4, i.e., on the side of the second layer of splicing film 4. When the top layer of splicing film 4 is lifted up, the blocking strip 7 can block the second layer of splicing film 4 to prevent the second layer of splicing film 4 from being lifted up by the top layer of splicing film 4. When the top layer of splicing film 4 is lifted up, the medical staff presses down the blocking strip 7, which causes the elastic block 6 below it to deform, and then the blocking strip 7 falls onto the elastic block 6 below. At this time, the blocking strip 7 is again located below the top layer of splicing film 4, i.e., on the side of the second layer of splicing film 4, to prepare for the next operation.

[0027] In order to further prevent the second layer of the connecting film 4 from being carried away by the top layer of the connecting film 4, before work, the blocking strip 7 is connected to the external air pump. During work, the air pump is controlled to ventilate the ventilation groove 1 7a, and the gas is then blown onto the second layer of the connecting film 4 through the ventilation groove 2 7b to press the second layer of the connecting film 4. At the same time, the wind diffusing upwards will blow up the end of the top layer of the connecting film 4 to facilitate the medical staff to hold it.

[0028] The technical principles of the embodiments of the present utility model are described above in combination with specific embodiments. These descriptions are only for explaining the principles of the embodiments of the present utility model, and cannot be interpreted in any way as limiting the protection scope of the embodiments of the present utility model. Based on the explanations here, technicians in this field can think of other specific implementation methods of the embodiments of the present utility model without creative work, and these methods will fall within the protection scope of the embodiments of the present utility model.
