Embodiment 1

[0040] refer to figure 1 , a disposable intraoperative frozen pathological tissue collection device, which mainly includes: a base plate 1, a fixing frame 2, a roller 3, a flexible film 4, a binding part 5, a freeze-thaw area 6, a drying area 7, and a tissue placement tank 8. Slot 9, temperature control knob 10, plug 11 and outlet pipe 12; where:

[0041] One end of the bottom plate 1 is provided with two sets of fixing frames 2, the rollers 3 are arranged between the two sets of fixing frames 2, the rollers 3 are parallel to the upper surface of the bottom plate 1, and the rollers 3 can use the fixing frames as fulcrums Rotate; the flexible film 4 is wound on the roller 3, so that the flexible film can be flattened on the upper surface of the bottom plate 1 before pathological tissue sampling.

[0042]The binding part 5 is arranged on the base plate 1 for fixing the flexible film laid on the surface of the base plate 1; the other end of the base plate 1 is a thawing area for...

Embodiment 2

[0046] A disposable intraoperative frozen pathological tissue collection device, the same as Example 1, the difference is: reference figure 2 , the flexible film 4 is provided with an easy-to-tear line 14, and the easy-to-tear line 14 is parallel to the axis of the roller 3; after the length of the flexible film on the surface of the bottom plate 1 meets the requirements, the easy-to-tear line 14 can be passed Disconnect the flexible membrane; at the same time, the flexible membrane can be used as a one-time sampling surface, which saves the time required to repeatedly rinse the table and dry it before the next specimen is collected each time, and improves the efficiency of sampling; Effectively prevent contamination between different specimens, easy to use, efficient and fast, and ensure that the pathological diagnosis report is issued within 30 minutes of sending the specimens.

[0047] refer to figure 2 , the two side edge positions of the flexible film 4 are provided wi...

Embodiment 3

[0049] A disposable intraoperative frozen pathological tissue collection device, the same as Example 1, the difference is: the size of the base plate 1 is: length 50-65cm, width 35-45cm, the material of the base plate is hard plastic, frozen The melting zone and drying zone are made of stainless steel.

Abstract

The invention belongs to the technical field of auxiliary devices for sampling pathological tissues, and particularly relates to a disposal device for sampling and collecting a frozen intraoperative pathological tissue and application of the device. The device includes: a bottom plate, supporting structures, a rolling shaft, a flexible film, binding components, a freezing and thawing area, a baking area, tissue placing grooves, insertion grooves, a water outlet pipe and so on; two groups of supporting structures are arranged on one end of the bottom plate, the rolling shaft is arranged betweenthe two groups of supporting structures, and the rolling shaft can rotate by taking the supporting structures as pivots; the flexible film is wound on the rolling shaft, the binding components are arranged on the bottom plate; the freezing and thawing area and the baking area are arranged on the other end of the bottom plate, and a heating device is arranged in the freezing and thawing area and the baking area; the tissue placing grooves are arranged in the freezing and thawing area; the insertion grooves are arranged in the baking area and the water outlet pipe communicates tissue thawing grooves. The device of the invention has the characteristic of being reliable and efficient with convenient use and can well solve the existing clinicopathological problem of fast freezing pathologicalsampling and specimen collection during an operation, and the timeliness and accuracy of freezing and thawing.

Description

technical field [0001] The invention belongs to the technical field of pathological tissue sampling auxiliary devices, and in particular relates to a disposable intraoperative frozen pathological tissue collection and sampling device and its application. Background technique [0002] The information disclosed in the Background of the Invention is only intended to increase the understanding of the general background of the invention, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. [0003] Intraoperative quick-frozen pathology refers to the rapid pathological diagnosis of the scope of surgical resection after the fresh tissue specimens submitted for examination are taken, prepared and stained, and the pathologist conducts intraoperative diagnosis to guide the rapid pathological diagnosis of the surgical resection area. It is required to issue a pa...
