Description

Technical Field

[0001] The utility model relates to the technical field of frozen pathological tissue sections, in particular to a freezing head sample tray with a digital display. Background Art

[0002] Pathological section testing requires a series of technical processing of the excised diseased tissues and organs, including fixation, sampling, dehydration, wax immersion, embedding, sectioning and staining. It usually takes 24 hours to complete the entire sectioning process. The pathologist then observes with a microscope and makes a diagnosis. Sometimes surgeons hope to understand the nature of the lesion immediately during the operation in order to determine the scope of the operation in time and make corresponding treatments. The pathologist is required to make a pathological diagnosis during the operation. At this time, rapid sectioning diagnosis is necessary. Rapid frozen sectioning is the most widely used method. The specific method is to fix the pathological tissue and OTC embedding agent together on the surface of the cryosection sample tray, then freeze-fix and then section.

[0003] The existing design of the cryostat sample tray requires the sample pathology number to be marked when slicing. The laboratory staff needs to write the patient number on a long strip of label paper in advance, and then embed one end of the long strip of label paper and the pathology sample in the OTC embedding agent. This numbering method is inefficient, and the small paper strip is easy to be damaged, or it may be lifted up and hit the slicer and wear the blade, which greatly reduces the work efficiency when the amount of freezing treatment is large during surgery. At the same time, the existing cryostat sample tray is difficult to clean due to the groove shape on its surface, and sometimes it is impossible to clean deep into the groove. Therefore, a cryostat sample tray with a digital display is proposed.

[0004] The existing patent (authorization announcement number: CN210863196U) discloses a universal sample support head for a frozen slicer, including a support platform, the top surface of the support platform is a supporting surface, and a plurality of small platforms are separated on the supporting surface. An annular groove is provided around the small platform, and the top surface of the small platform is flush with the supporting surface. The inventor found the following problems in the prior art during the implementation of the utility model: 1. In order to mark the pathological number of the sample, the sample support of the existing design needs to write the number on a label paper in advance, and then embed one end of the label paper and the pathological sample in an OTC embedding agent, which will wear the blade during slicing; 2. The sample support of the existing design is difficult to clean due to the grooves on its surface, and it is impossible to thoroughly clean to the deep of the groove. Utility Model Content

[0006] Fixed shafts are passed through both sides of the inner wall of the label box, and the surface of the fixed shafts passes through the inner walls of five groups of limit bearings. The outer walls of the limit bearings are attached with number plates.

[0007] Further preferably, a connecting rod is fixedly connected to one side of the bottom of the inner bracket, a slider is fixedly connected to one end of the connecting rod, a spring is fixedly connected to the other end of the connecting rod, a stopper is fixedly connected to one end of the spring, a moving button is fixedly connected to one side of the stopper, and the stopper forms an elastic structure with the connecting rod through the spring.

[0008] Further preferably, the label box and the support cover form an integrated structure, and the fixed shaft and the inner wall of the label box form an integrated structure.

[0009] Further preferably, the sizes of the five groups of limit bearings are consistent, and the limit bearings and the digital disk form an integrated structure, and the limit bearings and the fixed shaft form a rotating structure.

[0010] Further preferably, a groove is provided on the surface of the support cover, and the surface size of the inner bracket is consistent with the size of the groove on the surface of the support cover.

[0011] Further preferably, the inner bracket forms a movable structure between the slider and the inner wall of the support cover.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the utility model, by adding structures such as a label box, a fixed shaft, a limit bearing, and a digital disk, the device can facilitate laboratory personnel to number frozen tissues after slicing, thereby reducing the error rate and improving work efficiency.

[0014] In the utility model, by adding structures such as an inner bracket, a connecting rod, a slider, a stopper, a spring and a moving button, the inner bracket can be retracted when slicing, so that the OTC embedding agent and the sample are fixed on the support cover. When the support cover needs to be cleaned, the inner bracket can be slid out to make the surface of the support cover flat, which is convenient for cleaning the surface of the device.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 5 The utility model provides a technical solution: a freezing head sample tray with a digital display, comprising a base 1, a tray cover 2 is fixedly connected to the bottom of the base 1, an inner bracket 3 is attached to the inner wall of the tray cover 2, and a label box 4 is fixedly connected to one side of the outer wall of the tray cover 2.

[0023] Fixed shafts 401 penetrate both sides of the inner wall of the label box 4 , and the surface of the fixed shaft 401 penetrates the inner wall of five sets of limit bearings 402 , and the outer wall of the limit bearing 402 is attached with a number plate 403 .

[0024] The base, the support cover, the bracket and the label box of the utility model are made of low-temperature resistant materials, such as stainless steel, alloy steel and the like, to ensure that they will not become brittle or deformed within a temperature range of -50°C to 30°C.

[0025] In this embodiment, Figure 2 , Figure 3 and Figure 4As shown, a connecting rod 301 is fixedly connected to one side of the bottom of the inner bracket 3, a slider 302 is fixedly connected to one end of the connecting rod 301, a spring 303 is fixedly connected to the other end of the connecting rod 301, a stopper 304 is fixedly connected to one end of the spring 303, a moving button 305 is fixedly connected to one side of the stopper 304, and the stopper 304 forms an elastic structure with the connecting rod 301 through the spring 303. This structure can form a limiting structure between the inner wall of the support cover 2 and the inner bracket 3 through the stopper 304, thereby fixing the specific position of the inner bracket 3.

[0026] In this embodiment, Figure 1 , Figure 3 and Figure 5 As shown, the label box 4 and the support cover 2 form an integrated structure, and the fixed shaft 401 and the inner wall of the label box 4 form an integrated structure, which can provide a visible digital display position.

[0027] In this embodiment, Figure 1 , Figure 3 and Figure 5 As shown, the sizes of the five sets of limit bearings 402 are consistent, and the limit bearings 402 and the number plate 403 form an integrated structure, and the limit bearings 402 and the fixed shaft 401 form a rotating structure, which can change the numbers on the number plate 403.

[0028] In this embodiment, Figure 2 , Figure 3 and Figure 4 As shown, the surface of the support cover 2 is provided with a groove, and the surface size of the inner bracket 3 is consistent with the surface groove size of the support cover 2. This structure facilitates the inner bracket 3 to remain parallel to the surface of the support cover 2 when it is raised, so that the surface of the support cover 2 becomes a smooth plane.

[0029] In this embodiment, Figure 2 , Figure 3 and Figure 4 As shown, the inner bracket 3 forms a movable structure with the inner wall of the support cover 2 through the slider 302, and this structure facilitates the inner bracket 3 to be raised or lowered without affecting the device to fix the OTC embedding agent and tissue samples.

[0030] The material of the utility model is low temperature resistant material, for example, stainless steel, which will not become brittle or deformed within the range of -50°C to 30°C.

[0031] The use method and advantages of the utility model: When the freezing head sample holder with digital display is used, the working process is as follows:

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, first, the inner bracket 3 is retracted to a position close to the base 1, the OTC embedding agent and the tissue sample are fixed on the surface of the support cover 2, and the number plate 403 is turned in sequence, so that the number plate 403 displays different numbers as the limit bearing 402 rotates to mark the pathology number that needs to be recorded, and then it can be frozen and sliced. The device does not need to embed long strips of label paper in the OTC embedding agent, and will not cause wear on the slicer head; after the slicing is completed, if the device needs to be cleaned, the moving button 305 can be pressed to squeeze the spring 303, so that the stopper 304 loses its limiting effect, thereby moving the top of the inner bracket 3 to a position parallel to the top of the support cover 2 through the slider 302. At this time, the groove on the surface of the support cover 2 disappears, reducing the difficulty of cleaning.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected.
