Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically, it relates to a forceps for pathological slides. Background Technology
[0002] The pathology department is an indispensable department in large comprehensive hospitals. Its main task is to provide clinicians with a clear pathological diagnosis and determine the nature of diseases through biopsy, exfoliative, and fine-needle aspiration cytology. In biopsy, the tissue to be examined needs to be processed into paraffin blocks and then cut into paraffin slides. The slides need to be transferred to a slide spreader for unfolding, a process currently performed using forceps. Paraffin slides are generally 0.1-1.5 cm in diameter and no more than 1 μm thick. During the handling process, problems such as insufficient force causing the slide to fall off or excessive force causing it to break can easily occur. Often, multiple attempts are needed for a successful unfolding. Furthermore, electrostatic adhesion can sometimes occur, preventing the slide from detaching from the forceps and requiring repeated rubbing, which can also damage the slide. This process is not only time-consuming and labor-intensive but also affects the efficiency of the testing work.
[0003] In view of this, this utility model is hereby proposed. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide forceps for pathological slides. The basic concept of the technical solution adopted by this utility model to solve the above-mentioned technical problem is as follows:
[0005] A forceps for pathological sections, the forceps body includes two gripping arms and two grips with anti-static function. The grips are located at the cantilever ends of the gripping arms. The cantilever ends of the grips are provided with flexible clamping discs. The flexible clamping discs are disc-shaped with a diameter of 0.5 to 3 mm. The flexible clamping discs on the two grips can be fastened together.
[0006] Furthermore, the clamping arm and the chuck are an integral structure, and the flexible chuck is sleeved on the cantilever end of the chuck.
[0007] Furthermore, the chuck is provided with a blind hole-shaped groove, and is fitted onto the cantilever end of the clamping arm through the groove.
[0008] Furthermore, the flexible chuck and the chuck are an integral structure.
[0009] Furthermore, the flexible clamp is made of silicone.
[0010] Furthermore, the tweezers body also includes a light lamp and a power supply connected to the light lamp. The light lamp is disposed on the outer wall of one of the grippers and close to the flexible chuck. The power supply is disposed on the outer wall of the gripping arm and is located on the same gripping arm as the gripper where the light lamp is located.
[0011] Furthermore, the power supply is installed inside the housing, which is attached to the clamping arm. A switch is provided on the housing and connected in series between the power supply and the lighting lamp.
[0012] Furthermore, the lighting lamp is an LED lamp, the power source is a button battery, the voltage of the button battery is 1.5V, and the diameter is 5.8mm or 6.8mm.
[0013] Furthermore, the chuck is made of metal and its outer surface is coated with an antistatic coating.
[0014] Furthermore, the chuck is made of an antistatic material.
[0015] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art.
[0016] This invention features a chuck with anti-static properties, preventing the wax sheet from being difficult to remove from the tweezers due to static electricity. The flexible clamping plate at the end of the chuck effectively reduces the probability of damage to the wax sheet caused by traditional rigid clamping. At the same time, the flexible design alleviates the operator's fear of damaging the sheet and thus reduces the possibility of the wax sheet falling off due to insufficient clamping force. This ensures efficient operation in the sheet pulling and clamping process and improves testing efficiency.
[0017] The photo light designed in this invention effectively improves the brightness of the operating area and enhances visibility, thereby ensuring reliable clamping operations. This invention features a simple structural design, can be upgraded from existing tweezers, is low-cost, easy to operate, and is more competitive than new product iterations, facilitating widespread adoption.

Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0026] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1
[0028] like Figure 1 As shown in this embodiment, a pathological slide forceps includes two gripping arms 1, two clamps 2, a light 4, and a power supply. The clamps 2 are located at the overhanging ends of the gripping arms 1, meaning one clamp 2 corresponds to one gripping arm 1. The clamps 2 are anti-static, preventing interference from static electricity when gripping paraffin slides. The overhanging ends of the clamps 2 are equipped with flexible clamping discs 3. As the name suggests, the flexible clamping discs 3 are flexible, unlike rigid ones. Ordinary medical forceps generally have rigid arms, which inevitably damage paraffin slides when gripping them. The flexible clamping discs 3, being non-rigid, provide cushioning, reducing the probability of damaging the paraffin slides during operation and indirectly improving work efficiency.
[0029] The flexible clamping disc 3 here is disc-shaped with a diameter of 0.5-3mm. The size of the wax slices cut from the wax block is generally within the range of 0.1-1.5cm. The disc is controlled within this range to avoid being too large or too small, which would affect the clamping of the wax slices. Preferably, the diameter of the disc is 1mm. The flexible clamping discs 3 on the two clamps 2 can be snapped together. That is, when the clamping arms 1 are brought together by force, the two flexible clamping discs 3 are pressed together and stacked to clamp the wax slices in the middle. This changes the traditional point force to surface force, reducing the force per unit area of the wax slices and thus reducing the probability of damaging the wax slices.
[0030] In this example, the clamping arm 1 and the clamp head 2 are an integral structure, meaning the clamp head 2 can be considered part of the clamping arm 1. Medical forceps are mostly made of metal; to ensure the anti-static effect of the clamp head 2, an anti-static coating can be applied to the outer surface of the clamp head 2. Anti-static coatings are widely used in existing technologies and can be selected according to requirements. The flexible clamping disc 3 can be made of silicone and directly fitted onto the clamp head 2. Preferably, anti-static silicone can be used to ensure the anti-static effect. Furthermore, this structural design has another advantage: a flexible clamping disc can be directly fitted onto an existing forceps, modifying the forceps described in this embodiment, resulting in lower modification costs compared to producing a new product.
[0031] When handling the wax sheet with tweezers, the small size of the wax sheet means that normal desk lamp lighting is insufficient to ensure the required visibility. Therefore, in this example, the tweezers body is designed with a light source 4 and a power supply (…). Figure 1 Not shown in the image, please refer to the following: Figure 3 The photo light 4 is mounted on the outer wall of one of the clamps 2, close to the flexible clamping plate 3, and can be adhesively attached to the outer wall of the clamp 2. The power supply is located on the outer wall of the clamping arm 1, on the same clamping arm 1 as the clamp 2 containing the photo light 4. The power supply and the photo light 4 are connected by a wire 7. That is, the photo light is attached to the lower part of the outer side of the single clamping arm 1, and the power supply is attached near the top. The wire 7 can also be directly attached to the outer wall of the clamping arm 1 and the clamp 2. The power supply can be installed inside the housing 5, which can both protect the power supply and facilitate the adhesive connection between the housing 5 and the clamping arm 1. A switch 6 is provided on the housing 5, connected in series between the power supply and the photo light 4, and the switch 6 controls the on and off of the photo light.
[0032] The light 4 here is for providing a small area of illumination when holding the wax sheet. Since the light body is relatively small, an LED light is suitable. LED beads are small, meeting the requirements of a small size, and also offer good brightness and energy efficiency. A button battery is preferable as the power source; preferably, a 1.5V button battery with a diameter of 5.8mm or 6.8mm is preferred. After being installed at the top of the tweezers, its size and weight will not change significantly, thus reducing its impact on the operation of the tweezers. Example 2
[0033] like Figure 2-3 As shown, the difference between this embodiment and the first embodiment described above is that the chuck 2 has a blind-hole-shaped groove 201, which is fitted onto the cantilever end of the clamping arm 1. The chuck 2 and the flexible clamping plate 3 are an integral structure, and both are made of antistatic silicone. Specifically, in this example, the chuck 2 is an independent component that can be detachably installed on the cantilever end of the clamping arm 1. The size of the chuck 2 is much larger than the size of the flexible clamping plate 3. Setting them as an integral structure makes it easier to install the flexible clamping plate 3, and the stability of the flexible clamping plate 3 is more stable during clamping operations.
[0034] In this embodiment, the lighting lamp 4 and power lamp can be installed together with the clamp 2, making it easier to directly modify existing tweezers and upgrade ordinary tweezers to the tweezers described in this utility model. This design takes into account factors such as cost and replacement, and uses a quick component installation method instead of purchasing new instruments. It has the advantages of short instrument upgrade cycle, simple replacement operation, and low cost, making it more competitive and conducive to promotion and application.
[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
