Embodiment Construction

[0029] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0030] In the present disclosure, unless stated otherwise, the used orientation words such as "front and rear" refer to the direction in which the peeler extends, the hook-shaped head faces forward, and the handle part faces rear. "Inside and outside" refers to the outline of the device itself.

[0031] Such as figure 1 As shown, the present disclosure provides a stripper, which includes an operation part 2 and a handle part 1 that are coaxially connected in sequence from front to back. The angle formed by the operating part 2 is 90°, and a cutting knife 4 is formed inside the angle between the hook-shaped head 3 and the operating part 2 , and the blade of ...

Abstract

The invention relates to an elevator. The elevator comprises an operation portion (2) and a hand-held portion (1) which are coaxially connected successively from front to back. The front end of the operation portion (2) is laterally bended to form a hook-shaped head (3). An included angle formed by the hook-shaped head (3) and the operation portion (2) is 90 DEG. A cutter knife (4) is formed at aninner side of the included angle formed by the hook-shaped head (3) and the operation portion (2). A blade of the cutter knife (4) is parallel to an extension direction of the hook-shaped head (3). The elevator has cutting and separating functions and can be used for separation of important blood vessels and nerves and sharp incision of superficial tissues, and the number of operating apparatusesin a narrow surgical space is reduced. The cutting blade is formed at the inner side of the hook-shaped head of the elevator, the cutting edge is positioned below the hook-shaped head, and the cutting direction is consistent with the axial direction of the operation portion, thereby facilitating operation in a narrow and long space. Requirements of a deep skull base surgery can be satisfied.

Description

technical field [0001] The present disclosure relates to a surgical instrument, and in particular, to a dissector. Background technique [0002] Microdissections are used to separate and protect important nerves and blood vessels during surgery. Microdissections of different shapes and lengths are used for separation during surgery. Due to the narrow surgical field and numerous important blood vessels and nerves in skull base surgery, it is necessary to The separation operation is performed in a narrow gap, so the microdissection is very important to ensure the safety of the operation and improve the quality of the operation. [0003] Existing dissectors have fewer cutting parts during application, and are difficult to operate in deep narrow spaces, and are difficult to meet the requirements of skull base surgery. Contents of the invention [0004] The purpose of the present disclosure is to provide a dissector, which can solve the technical problem that the existing diss...
