Description

Technical Field

[0001] This utility model relates to the field of electric heating forceps technology, and in particular to a local electric heating forceps for tissue embedding. Background Technology

[0002] During tissue embedding, because the temperature of the embedding machine is lower than that of the dehydrated tissue in the paraffin bath, tissue may stick to the working part of the forceps, causing tissue damage. To address this issue, some research has been conducted on electrically heated forceps, but these mainly suffer from problems such as large size and weight, making them inconvenient to operate; relatively complex heating temperature control; and unstable heating temperature of the forceps.

[0003] For example, Chinese utility model patent application number 201020629353.5, entitled "A Forceps for Grasping Tissue During Embedding," uses a temperature controller to heat the gripping end of the forceps to a set high temperature, which can easily melt the attached wax block, thus ensuring no tissue residue and uniform solidification of the embedded wax block, thereby ensuring the smooth and accurate process of the entire pathological analysis. However, it requires a temperature controller for temperature control, and the heating element is a heating wire or heating tube. After reaching a certain temperature, heating stops, and the temperature is lowered to a certain level before being raised again. This causes temperature differences within the forceps, and the heating element is exposed at the outer end of the gripping head, making the forceps larger and less convenient to operate.

[0004] For example, Chinese utility model patent application number 202221541575.0, entitled "A Pathological Embedding Forceps with Automatic Heating to Prevent Paraffin Solidification," allows for heating of the gripping tips as needed, effectively preventing paraffin solidification during gripping. The use of a charging cable and USB connector facilitates charging of the power supply by medical personnel. The heat-insulated handle effectively prevents burns. However, its structure is not that of traditional forceps; it resembles a clamp more, and its size and weight are relatively large, making it inconvenient to operate.

[0005] For example, Chinese utility model patent application number 202322522177.5, entitled "A Forceps for Heating Embedding," uses a heating sleeve fitted over the retractable head of the forceps body to heat the forceps, thus preventing the liquid paraffin from solidifying and adhering to the forceps body after a brief separation. However, it uses a heating block inside the heating sleeve for heating, resulting in a relatively large structure and weight, making it inconvenient to operate. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a local electric heating forceps for tissue embedding, which is small in size, light in weight, more convenient to hold and operate, and has high temperature stability.

[0007] This utility model is achieved using the following technical solution: a local electric heating forceps for tissue embedding, comprising a forceps body, wherein two heating plate grooves are symmetrically arranged on the inner side of the front end of the forceps body, and two wire grooves are also symmetrically arranged on the inner side of the forceps body, wherein the wire grooves extend from the heating plate grooves to the top of the forceps body, wherein an electric heating plate is fixed in the heating plate groove, and two wires are connected to each electric heating plate, wherein the wires are arranged in the wire groove; wherein a power plug is connected to the rear end of the wires, and the power plug is used to supply power to the electric heating plate.

[0008] Furthermore, a wire limiting seat is fixed to the top of the tweezers body, and a through hole is provided in the center of the wire limiting seat, through which the rear end of the wire passes.

[0009] Furthermore, the electric heating element is sealed in the groove of the heating element with silicone.

[0010] Furthermore, the outer side of the middle part of the tweezers body is provided with an anti-slip texture, and a raised ring is provided at the upper and lower ends of the anti-slip texture on the outer side of the tweezers body.

[0011] Furthermore, the electric heating element is a polyimide electric heating film.

[0012] Furthermore, the rated voltage of the electric heating element is no greater than 5V.

[0013] Furthermore, the width and length of the electric heating element are no greater than 3mm × 15mm.

[0014] Furthermore, the thickness of the electric heating element is no greater than 0.3 mm.

[0015] Compared to existing technologies, the advantages of this invention are as follows: The locally electrically heated forceps for tissue embedding of this invention have a small and thin heating element, eliminating the need to increase or thicken the forceps body. This results in minimal difference in size and weight compared to traditional forceps in the prior art, making them more convenient to hold and operate. Furthermore, it eliminates the need for an additional temperature controller, ensuring high temperature stability and facilitating rapid and precise embedding operations. Attached Figure Description

[0019] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0020] The purpose of this invention is to address the shortcomings of existing technologies by providing a locally electrically heated forceps for tissue embedding.

[0021] Example 1

[0022] This embodiment provides a locally electrically heated forceps for tissue embedding, referring to... Figures 1-2 As shown, the device includes a tweezers body 10, which is a conventional tweezers structure with a length of 13-18 cm. It includes two tweezers handles, the top ends of which are connected and fixed, allowing the tweezers to grip tightly under force and extend freely when no force is applied. Two heating element grooves 12 are symmetrically arranged on the inner side of the front end of the tweezers body 10. Two wire grooves 13 are also symmetrically arranged on the inner side of the tweezers body 10, extending from the heating element grooves 12 to the top of the tweezers body 10. A wire hole is provided at the top of the tweezers body 10. An electric heating element 2 is fixed within the heating element groove 12, and two wires 4 are connected to each electric heating element 2. The wires 4 are disposed within the wire groove 13. In this embodiment, the electric heating element 2 is sealed in the heating element groove 12 with silicone. The rear end of the wire 4 is connected to a power plug 5, which is used to supply power to the electric heating element 2. The power plug 5 can be inserted into a mains socket or a battery power supply. In this embodiment, the power plug 5 is inserted into a 220V mains socket, which can step down the 220V AC power to a DC voltage of less than 5V for output.

[0023] Reference Figures 1-2As shown, a wire limiting seat 3 is fixed to the top of the tweezers body 10. A through hole is provided in the center of the wire limiting seat 3, and the rear end of the wire 4 passes through the through hole in the center of the wire limiting seat 3. Specifically, in this embodiment, the electric heating element 2 is a polyimide electric heating film. The rated voltage of the electric heating element 2 is no greater than 5V, and the power is 0.5~1.8W. In this embodiment, the width and length of the electric heating element 2 are no greater than 3mm×15mm, the thickness is no greater than 0.3mm, and the diameter of the wire 4 is no greater than 0.5mm. This makes the dimensions of the heating element groove 12 and the wire groove 13 relatively small. Therefore, it is not necessary to increase the size of the tweezers body 10 when configuring the heating function, so that the difference in size and weight between it and the traditional tweezers in the prior art is very small, making it more convenient to hold and operate. A section of anti-slip texture 11 is provided on the outer side of the middle part of the tweezers body 10. A raised ring 14 is provided on the outer side of the tweezers body 10 at the upper and lower ends of the anti-slip texture 11, respectively, to facilitate hand operation.

[0024] This invention relates to a local electric heating forceps for tissue embedding. A heating element groove 12 and a wire groove 13 are provided on the inner side of the forceps body 10. Heating and conductivity are achieved by encapsulating an electric heating element 2 and a wire 4 within these grooves. Since the electric heating element 2 in this invention uses a polyimide electric heating film, which is small in size and thinner, the heating function can be configured without increasing or thickening the size of the forceps body 10. This results in minimal difference in size and weight compared to traditional forceps in the prior art, making it more convenient to hold and operate. The rear end of the lead wire 4 passes through the wire hole of the tweezers body and the central through hole of the lead wire limiting seat 3 to connect to the power plug 5. Since the electric heating element 2 uses a polyimide electric heating film, its resistance stability is good. When the current passes through the electric heating film, the electrical energy is converted into heat energy due to the resistance of the material, so that the heat can be output stably. There is no need to set up an additional temperature controller for temperature control. This avoids the need to configure a temperature controller for heating components such as electric heating wires in the existing technology. Moreover, the heating components have changes such as heating, cooling and heating, which makes the temperature of the tweezers not stable enough, affecting the rapid and accurate completion of the embedding work.

[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
