Abstract

The invention discloses a skin tissue drilling device. The skin tissue drilling device comprises a handle and an annular drill bit which are connected with each other, and an observation hole is formed in the side wall of the annular drill bit, and formed in the axial direction of the annular drill bit; the observation hole is a kidney-shaped hole; a set of concave openings are formed in a blade of the annular drill bit along the circumference; the blade of the annular drill bit is in a circular truncated cone shape. When skin biopsy is conducted, through the observation hole, the biopsy depthcan be directly observed, and thus the sampling accuracy and reliability are improved; the annular drill bit is provided with the concave openings, so that the concave openings are in a sawtooth shape, the blade is in the circular truncated cone shape, and rotary drilling during skin biopsy is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a skin tissue drill. Background technique [0002] Skin biopsy is a pathological examination method commonly used in dermatology. It refers to excision or trepanation of a certain part of the skin or mucosal tissue, and through tissue staining to clarify or suggest a certain diagnosis. It is used to diagnose skin tumors, viral skin diseases, bullous skin diseases, psoriasis, lichen planus and skin diseases where pathogens can be found, leprosy, deep fungal diseases, etc. Skin biopsy plays a decisive role in the diagnosis of the disease. However, biopsy is an invasive operation, and clinicians must consider the nature of the damage, the diagnostic accuracy of biopsy, whether it will affect the beauty and the site of biopsy. Skin biopsy includes: cutting biopsy, punch biopsy, excisional biopsy, wedge excision biopsy. [0003] Punch biopsy is widely used by clinicians bec...
