Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and more particularly to a disposable skin biopsy sample collector. Background Art

[0002] Skin biopsy is a traumatic clinical examination. It is done by taking local samples of skin lesions and performing histopathological examination to achieve the ultimate goal of clinical diagnosis or treatment. The skin is not a thin layer as we imagine, but a three-dimensional structure. The skin contains many appendages, such as hair follicles, sweat glands, blood vessels, etc. Skin diseases are caused by lesions of these structures. However, these structures are microscopic structures and cannot be seen by the naked eye. The specific situation of the lesion can only be discovered by cutting the tissue and observing it under a microscope.

[0003] At present, there are three main methods for collecting skin tissue pathology specimens: surgical excision, trephine method and cutting method. The most commonly used method in clinical practice is trephine biopsy, because it causes little damage and can reach a certain cutting depth. Trephine biopsy uses a hollow circular scalpel to cut lesions on the skin. The trephine rotates clockwise and counterclockwise to cut the skin with a thickness of about 4 mm to reach the fat tissue layer below the dermis. Then the cut tissue sample is taken out and examined under a microscope. After the sample is collected, the skin defect is circular, which is not easy to suture, and it is easy to form a scar-like appearance after suturing. However, the cutting method is not easy to operate, has poor stability, low efficiency, large wound surface, low cutting accuracy, and a lot of bleeding, which is limited in clinical application. In view of this, the inventor proposes a disposable skin biopsy sampler. Summary of the invention

[0004] The purpose of the present invention is to provide a disposable skin biopsy specimen collector to solve the above problems.

[0005] The above technical purpose of the present invention is achieved through the following technical scheme: a disposable skin biopsy sample collector, including a biopsy plate and a biopsy knife, the biopsy plate includes an elastic support, the two ends of the elastic support are fixedly connected with mounting parts, and the mounting parts are fixedly connected to the biopsy knife.

[0006] The present invention is further configured as follows: one end of the mounting member away from the elastic bracket is fixedly connected to a connecting member, and one end of the connecting member away from the elastic bracket is fixedly connected to an inclined plate.

[0007] The present invention is further configured such that: an arc-shaped plate is provided at one end of the inclined plate away from the elastic bracket.

[0008] The present invention is further configured as follows: a plurality of friction teeth are provided on the arc-shaped plate.

[0009] The present invention is further configured such that the included angle of the inclined plate is 60° - 80°.

[0010] The present invention is further configured such that mounting portions are provided at both ends of the biopsy knife, mounting holes are provided in the middle of the mounting portions, and the biopsy knife is fixedly connected to the biopsy plate through the mounting portions and the mounting holes.

[0011] The present invention is further configured such that a reinforcing plate is provided between the connecting member and the mounting member.

[0012] In summary, the present invention has the following beneficial effects: The present invention is held by the thumb and index finger through the arc-shaped plate, and then, due to the elastic force of the elastic support and the biopsy knife, it bends outward at a certain angle, and the blade can be used to perform biopsy and extraction work on the affected area of the patient, which is beneficial to reducing the trauma surface and is not likely to leave scars.

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Embodiment:

[0019] A disposable skin biopsy sampler, as Figure 1 , Figure 2 and Figure 3 shown, includes a biopsy plate 1 and a biopsy knife 2. The biopsy plate 1 includes an elastic support 101. Mounting members 102 are fixedly connected to both ends of the elastic support 101, and the mounting members 102 are fixedly connected to the biopsy knife 2.

[0020] In this embodiment, one end of the mounting member 102 away from the elastic bracket 101 is fixedly connected to a connecting member 103, and one end of the connecting member 103 away from the elastic bracket 101 is fixedly connected to an inclined plate 105.

[0021] In this embodiment, an arc-shaped plate 106 is provided at one end of the inclined plate 105 away from the elastic bracket 101.

[0022] In this embodiment, a plurality of friction teeth 107 are provided on the arc-shaped plate 106, which can increase friction and facilitate the user's grip.

[0023] In this embodiment, the included angle of the inclined plate 105 is 60° - 80°. In this embodiment, the optimal included angle is 70°.

[0024] In this embodiment, mounting portions 201 are provided at both ends of the biopsy knife 2, and a mounting hole 202 is provided in the middle of the mounting portions 201. The biopsy knife 2 is fixedly connected to the biopsy plate 1 through the mounting portions 201 and the mounting hole 202.

[0025] In this embodiment, a reinforcing plate 104 is provided between the connecting member 103 and the mounting member 102. Working principle and usage method:

[0026] During use, the thumb and index finger are used to hold through the arc-shaped plate. Then, by virtue of the elasticity of the elastic bracket and the biopsy knife, it bends outward at a certain angle, and the blade can be used to perform biopsy and extraction work on the affected area of the patient. At the same time, the friction teeth in the arc-shaped plate can increase friction, facilitating the medical staff to hold and bend.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
