Description

Technical Field

[0001] The utility model belongs to the technical field of medical pathology, and in particular relates to a pathological tissue sampling and clamping device. Background Art

[0002] Pathological tissue refers to abnormal or diseased tissue observed in histology and pathology. These tissues typically develop in disease states, particularly cancer, inflammation, or other pathological conditions. In medical research and diagnosis, the study of pathological tissue helps understand the mechanisms, progression, and effects of disease. The structure and function of normal tissue are determined by the morphology, arrangement, and function of cells. When tissue is damaged, infected, or affected by other pathological factors, its structure and function may change, resulting in pathological tissue. These changes can include cellular atypia (abnormal cell morphology), cell proliferation (increase in cell number), necrosis (cell death), and other morphological changes. In pathology, analysis of pathological tissue is typically performed through microscopy. Pathologists stain and process tissue samples to reveal detailed information about their internal structure. Common staining techniques include H&E (hematoxylin and eosin) staining, which clearly displays distinct features of the cell nucleus and cytoplasm. These techniques enable pathologists to identify abnormal cells within tissues, tumor type and grade, and signs of infection.

[0003] When clamping pathological tissue samples, the clamping device is not stable enough, and the samples are prone to slipping or even being lost. Utility Model Content

[0004] In view of this, the present invention provides a pathological tissue sampling clamping device, which aims to solve the problem that when clamping pathological tissue samples, the clamping device is not stable enough, and the samples are prone to slipping or even losing.

[0005] The utility model is achieved in this way:

[0006] The utility model provides a pathological tissue sampling clamping device, which includes a clamping handle, a support arm connected to the clamping handle, and a clamping head connected to the support arm; the surgical support arm is provided with two, and the two support arms are arranged opposite to each other; the clamping head is connected to one end of the support arm away from the clamping handle, and the clamping head is provided with two, and the clamping heads are arranged relatively spaced apart; the width of the clamping head gradually decreases from one end of the support arm toward the direction away from the support arm, the thickness of the clamping head gradually decreases from one end of the support arm toward the direction away from the support arm, and the maximum thickness of the clamping head is less than or equal to one third of the thickness of the support arm; the inner side surface of the clamping head is a clamping surface, and the two corners of the clamping surface are provided with outwardly protruding arc chamfers; the surfaces of the clamping surface and the arc chamfers are both smooth surfaces; the width of the support arm gradually decreases from the clamping handle toward the clamping head, and the maximum width of the clamping head is less than the minimum width of the support arm.

[0007] The technical benefits of the pathological tissue sampling clamping device provided by this utility model are as follows: The provision of a clamping block enhances the gripping and stabilization capabilities of the clamping head. The thorn-like structure of the clamping block more effectively penetrates and secures pathological tissue during the clamping process, preventing it from slipping or falling out, thereby improving sampling accuracy and integrity. This design helps ensure that the clamping device can stably grasp and retain tissue samples during the tissue sampling process, reducing slippage or loss during operation and improving the success rate and quality of sampling.

[0008] On the basis of the above technical solution, the pathological tissue sampling clamping device of the present invention can also be improved as follows:

[0009] Wherein, one end of the support arm connected to the clamping head has a transition portion.

[0010] Furthermore, the clamping handle is arranged in a flat shape.

[0011] Furthermore, a clamping block is provided on the inner side wall of the clamping head.

[0012] Furthermore, the clamping handle and the support arm are integrally formed, and the clamping head is detachably connected to the support arm.

[0013] Furthermore, the outer side surface of the support arm is provided with anti-slip grooves.

[0014] Furthermore, the anti-slip pattern includes a plurality of convex strips arranged at intervals.

[0015] Furthermore, a plurality of the clamping blocks are provided.

[0016] Furthermore, the clamping block is a thorn-shaped structure.

[0017] Furthermore, the length of the clamping block is 2 mm.

[0018] Compared with the prior art, the pathological tissue sampling clamping device provided by the present invention has the following beneficial effects: by providing a clamping block, the clamping head's ability to grasp and stabilize tissue can be enhanced. The thorn-like structure of the clamping block can more effectively penetrate and secure pathological tissue during the clamping process, preventing the tissue from slipping or falling off, thereby improving the accuracy and integrity of sampling. This design helps ensure that the clamping device can stably grasp and hold tissue samples during tissue sampling, reducing slippage or loss during operation and improving the success rate and quality of sampling. It can also solve the problem of insufficient stability of the clamping device when clamping pathological tissue samples, which can easily cause the sample to slip or even be lost.
