Description

Technical Field

[0001] The utility model relates to the technical field of pathology, and more specifically to a tissue wax block auxiliary knockout device. Background Art

[0002] During the pathological examination process, it is often necessary to make multiple tissue wax blocks at a time. The basic process of making tissue wax blocks is: first place a metal embedding frame, then place the dehydrated tissue wax block inside the metal embedding frame, then place a plastic embedding frame on top of the metal embedding frame, with a certain space between the two to accommodate the tissue block and paraffin, then add hot liquid paraffin between the metal embedding frame and the plastic embedding frame, wait for the hot liquid paraffin to cool down and become cold solid paraffin, and finally use external force to separate the metal embedding frame from the solid wax block for demolding.

[0003] It takes a long time for hot liquid paraffin to cool naturally into cold solid paraffin, so technicians usually place the metal embedding frame on top of ice to accelerate cooling. After cooling, demolding is performed. Since the metal embedding frame is tightly adhered to the paraffin, technicians usually use methods such as inserting tools between the metal embedding frame and the plastic embedding frame to pry or knock them apart to separate the metal embedding frame from the solid wax block. The above-mentioned demolding process is time-consuming and labor-intensive, and requires manual demolding one by one. The process is cumbersome, and the problem that the metal embedding frame in contact with the ice is cold, smooth, and difficult to hold must be overcome. Therefore, providing a tissue wax block auxiliary knocking device that can free both hands and improve work efficiency and quality has become a problem that needs to be solved urgently by technicians in this field. Utility Model Content

[0004] The utility model provides a tissue wax block auxiliary knocking device, which aims to replace the backward manual operation process, reduce the cumbersome manual operation, improve the adhesion between the metal embedding frame and the paraffin, and improve the separation efficiency between the metal embedding frame and the solid wax block.

[0005] The technical solution adopted by the utility model is to provide a tissue wax block auxiliary knocking device, including a wax block mold and a wax block knocking mechanism, the wax block knocking mechanism includes a mold connector, a collecting mounting part, a driving device and a knocking piece, the mold connector has an internal limit clamping connection with a plurality of the wax block molds, the collecting mounting part is groove-shaped, the mold connector is limitedly placed inside the collecting mounting part, the knocking piece is rotatably connected to the collecting mounting part and is located above the mold connector, and the driving device drives the knocking piece. In the above components, the collecting mounting part serves as a frame connecting other components, and collects tissue wax blocks and debris that fall when knocked; the mold connector is used to fix the wax block mold to prevent it from falling out when knocked; the driving device drives the knocking piece to repeatedly hit the multiple molds located on the mold connector, so that the tissue wax block falls out of the mold, automatically completing the demolding process and saving manpower.

[0006] Furthermore, the collecting mounting part includes a rear plate, a side plate, a symmetrical mounting plate, a wax block collecting basket and a debris collecting trough, the side plate and the symmetrical mounting plate are respectively connected to the rear plate, the symmetrical mounting plate is installed between the two side plates, and the bottom of the symmetrical mounting plate is higher than the bottom of the side plate; the inner wall of the side plate and the side wall of the symmetrical mounting plate are both provided with a plurality of slide grooves, the mold connector and the wax block collecting basket are installed between the symmetrical mounting plate and the side plate through the slide grooves, and the mold connector is located above the wax block collecting basket; the debris collecting trough is installed between the two side plates through the slide grooves and is located below the wax block collecting basket; the surface of the wax block collecting basket is evenly provided with a plurality of through holes. A symmetrical mounting plate is provided to simultaneously place two or more rows of molds in the tissue wax block auxiliary knockout device to improve efficiency. A wax block collection basket is provided which is limitedly slidably connected to the aggregate frame, so as to collect the wax blocks which fall when knocking and demolding, and avoid breaking them and making them difficult to slice; through holes are provided on the surface of the wax block collection basket, and a debris collection groove is provided underneath, so as to collect the wax block debris which falls when knocking and demolding, and to remove the debris collection groove through the slide groove for cleaning.

[0007] Furthermore, the knocking member includes a limiter, a pressure strip and a pressure block. The limiter is fixedly mounted on the upper surface of the side panel, and the middle part of the pressure strip is rotatably connected to the limiter. The bottom of one end of the pressure strip close to the wax block mold is fixedly connected with a pressure block, which is recorded as the pressure block end, and the bottom of the other end is connected to the upper surface of the side panel through a spring, which is recorded as the spring end. The spring end is also connected to the driving device. When in use, the driving device is turned on, and the driving device drives the spring ends of multiple pressure strips to press down and compress the springs, and then the driving device is paused, and the spring pushes the spring end to rise rapidly, and the pressure block end of the pressure strip drops rapidly, driving the pressure block to knock on the back of the wax block mold, and then the driving device resumes work, and the cycle is repeated, so that the pressure block repeatedly knocks on the mold to promote the demolding of the internal paraffin.

[0008] Furthermore, the mold connector includes a mold frame and a limiting shell. The mold frame is U-shaped when viewed from above. The two side walls of the mold frame are provided with mold frame slide grooves. The wax block mold is slidably installed in the mold frame slide grooves. The two ends of the limiting shell are located in the mold frame slide grooves. The limiting shell is tightly attached to the wax block mold and seals one end of the U-shaped opening of the mold frame. The limiting shell includes a first extrusion limiting strip and a second extrusion limiting strip. The first extrusion limiting strip is connected to the second extrusion limiting strip through a spring. A limiting groove is provided on the upper surface of one end of the mold frame opening. The limiting groove is connected to the slide grooves on both sides of the mold frame. The outer surfaces of both ends of the limiting shell are rough. The design of the mold connector is conducive to sliding a plurality of the wax block molds in the slide grooves of the mold frame and placing them in a row. After the wax block mold is placed, the spring of the limit shell is compressed, the limit shell is placed in the slide grooves on both sides of the mold frame, and pushed toward the inner side of the opening of the mold frame to compress the multiple wax block molds to prevent gaps between the molds or the molds from falling out of the mold frame. The outer surfaces of both ends of the limit shell are rough, which is conducive to increasing the friction with the mold frame so that it does not move relative to the mold frame when it is knocked and vibrated.

[0009] Furthermore, an upper limit bar and a lower limit bar are provided between the symmetrical mounting plate and the side plate, and the mold frame is located between the upper limit bar and the lower limit bar. A support bar is provided between the mold frame and the lower limit bar, and the support bar is connected to the lower limit bar through a spring. A limit block is provided below the support bar, and the limit block is fixedly installed on the inner wall of the side plate. During use, the mold connector that is repeatedly knocked will squeeze the support bar, causing the support bar to drop, and the spring at the bottom of the support bar will be compressed, which will drive the mold connector to continuously rebound, so that the mold inside the mold connector hits the upper limit bar multiple times to demold the internal paraffin. The upper limit bar and the lower limit bar are provided to prevent the mold connector from falling out upward or downward when the knocking piece continuously knocks the wax block mold, and it is also beneficial for the mold connector to continuously rebound between the lower limit bar and the upper limit bar, and use inertia to promote demolding. The support bar plays a buffering role to prevent the mold connector from hitting the lower limit bar.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model obtains a tissue wax block auxiliary knocking device through the above design, which drives the knocking piece to hit the mold multiple times through the driving device, promotes the demolding of the paraffin inside the mold, and collects wax blocks and paraffin debris at the same time, thereby improving the efficiency of paraffin demolding, achieving the purpose of replacing manual work and improving work efficiency and quality, which is conducive to improving the operating status of the pathology technology industry and saving manpower and material resources.

In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0019] Example

[0020] See also Figure 1 and Figure 2The utility model provides a technical solution: a tissue wax block auxiliary knocking device, including a wax block mold 110, and also including a wax block knocking mechanism 200, the wax block knocking mechanism 200 includes a mold connector 230, the mold connector 230 is limitedly clamped with multiple wax block molds 110, the mold connector 230 is limitedly placed on both sides of the inside of the collecting mounting member 210, and knocking members 220 are installed on both sides above the collecting mounting member 210. The knocking member 220 knocks the wax block mold 110 through a telescopic motor 227 in conjunction with a spring and a pressure strip 221. When the spring quickly pushes the pressure strip 221 to knock the wax block mold 110, the internal paraffin falls off, thereby increasing the efficiency of demolding.

[0021] See also Figure 4 and Figure 6 The collecting mounting member 210 includes a side plate 211, a symmetrical mounting plate 212 is arranged between the two side plates 211, the side plates 211 and the symmetrical mounting plate 212 are connected by a rear plate 236, a debris collecting groove 218 and a wax block collecting basket 219 are arranged at the bottom of the side plate 211, and a plurality of through holes are evenly opened on the surface of the wax block collecting basket 219.

[0022] The inner walls of the two side panels 211 are fixedly mounted with a bottom mounting frame 213, which is in a U-shaped configuration. The debris collection trough 218 is limitedly slidably connected to the bottom mounting frame 213, so that the debris collection trough 218 can be conveniently inserted between the two side panels 211. A collection frame 214 is installed between the symmetrical mounting plate 212 and the two side panels 211, and the collection frame 214 is in a U-shaped configuration. The wax block collection basket 219 is limitedly slidably connected to the collection frame 214. The installation of two collection frames 214 allows both sides to work simultaneously, thereby increasing work efficiency.

[0023] See also Figure 3 , 4 and Figure 6 The mold connecting part 230 includes a mold frame 231 and a limiting shell 232. The mold frame 231 is U-shaped. The two side walls of the mold frame 231 are provided with sliding grooves. The two sides of the wax block mold 110 are slidingly installed in the sliding grooves of the mold frame 231. The limiting shell 232 limits the wax block mold 110 inside the mold frame 231. The mold frame 231 is located directly above the wax block collection basket 219, which is convenient for dropping the wax block into the wax block collection basket 219. There are through holes inside the wax block collection basket 219, and wax block debris passes through the wax block collection basket 219 and falls into the debris collection groove 218.

[0024] The middle part of the limiting shell 232 is hollow, and the first extrusion limiting strip 233 and the second extrusion limiting strip 234 are respectively installed on both sides of the limiting shell 232 for limiting sliding. The first extrusion limiting strip 233 and the second extrusion limiting strip 234 are connected by a spring. Limiting grooves 235 are provided on both sides above the open end of the mold frame 231. The grooves on both sides of the mold frame 231 are sunken into the slide grooves on both sides of the mold frame 231. The limiting shell 232 is correspondingly arranged with the limiting grooves 235. Pressing the first extrusion limiting strip 233 and the second extrusion limiting strip 234 squeezes the spring to retract the first extrusion limiting strip 233 and the second extrusion limiting strip 234 into the interior of the limiting shell 232. After the limiting shell 232 is placed in the groove at one end of the mold frame 231, the spring squeezes the first extrusion limiting strip 233 and the second extrusion limiting strip 234 to open, so as to facilitate the extrusion of the wax block mold 110 and prevent it from falling.

[0025] An upper limit bar 217 and a lower limit bar 215 are respectively arranged between the symmetrical mounting plate 212 and the side plate 211, and the mold frame 231 is located between the upper limit bar 217 and the lower limit bar 215. The upper limit bar 217 and the lower limit bar 215 are used to support and limit the mold connector 230 to facilitate knocking by the knocking piece 220.

[0026] A support bar 216 is connected to the top of the lower limit bar 215 through a spring. The support bar 216 is installed on the side plate 211 and the side wall of the symmetrical mounting plate 212 for limiting sliding. The support bar 216 is located below the mold frame 231. There are multiple support bars 216. Limiting blocks are provided below the multiple support bars 216 to prevent the support bars 216 from descending too much to reduce the knocking effect of the knocking piece 220. The support bars 216 are used to increase the number of impacts of the mold connector 230 after the knocking piece 220 has knocked, so as to achieve a better demolding effect.

[0027] See also Figure 4 and Figure 5The knocking piece 220 includes a pressure strip 221, and the two sides of the pressure strip 221 are rotatably limited and installed above the side plate 211 through limit blocks 222. The bottom of the pressure strip 221 close to the wax block mold 110 is fixedly connected with a pressure block 223, and the bottom of the pressure strip 221 away from the wax block mold 110 is fixedly installed with an upper spring seat 224. A lower spring seat 225 is fixedly installed at the corresponding position of the side plate 211 and the upper spring seat 224. The upper spring seat 224 and the lower spring seat 225 are connected by a spring, and a telescopic motor 227 is installed above the side plate 211 through a mounting frame 229. There are multiple groups of pressure strips 221, and the multiple groups of pressure strips 221 are connected for limited rotation through a limiting connecting rod 226. A limiting pressing plate 228 is fixedly connected to the bottom of the telescopic motor 227. The limiting pressing plate 228 and the limiting connecting rod 226 are correspondingly arranged. The pressure block 223 under the pressure strip 221 and the wax block mold 110 are correspondingly arranged. The upper spring seat 224 and the lower spring seat 225 are used for limiting the connection of the spring. The pressure block 223 is tilted to increase the contact area between the pressure block 223 and the bottom of the wax block mold 110. At the same time, the pressure block 223 is made of rubber to reduce damage to the wax block mold 110.

[0028] Working principle: Place multiple wax block molds 110 in the mold frame 231, press the first extrusion limit strip 233 and the second extrusion limit strip 234 to retract them into the limit shell 232, and place the limit shell 232 in the limit groove 235 at one end of the mold frame 231. After being placed, the internal spring squeezes and stretches the first extrusion limit strip 233 and the second extrusion limit strip 234 to limit the multiple wax block molds 110, inject paraffin wax into the wax block mold 110 for heating and cooling, etc. After the operation is completed, insert the mold connector 230 between the support strip 216 and the upper limit strip 217, turn on the telescopic motor 227, and extend and retract. The retracting motor 227 will press the limit connecting rod 226, and the limit connecting rod 226 will drive one end of the multiple pressure strips 221 to be pressed down. When pressed to the lowest point, the retracting motor 227 will retract quickly. At this time, the spring will push one end of the pressure strip 221 to rise quickly, and the other end of the pressure strip 221 will drive the pressure block 223 to knock on the back of the wax block mold 110. While knocking, the mold connector 230 will squeeze the support bar 216 to make the support bar 216 drop. The spring at the bottom of the support bar 216 is compressed, which will drive the mold connector 230 to rebound continuously, so that the mold inside the mold connector 230 hits the upper limit bar 217 multiple times to demold the internal paraffin.
