Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and examples, and the contents of the examples are not intended to limit the protection scope of the present invention.

[0033] figure 1 A schematic diagram of the detachable ear surgical instrument of the present invention is shown. like figure 1 As shown, the detachable ear surgery instrument of the present invention includes a handle 1 , a locking sleeve 2 and an instrument shaft 3 . Wherein, the handle 1 is used for the operator to hold during the operation. The locking sleeve 2 is used for removably installing the instrument rod 3 on the handle 1 . In the present invention, since the instrument shaft 3 is detachably mounted on the handle 1 through the locking sleeve 2, one handle with multiple heads can be realized, so that one instrument can meet multiple purposes and more Clinical needs, reduce energy consumption.

Abstract

The invention relates to a detachable otologic surgical instrument which comprises a handle (1), a locking sleeve (2) and an instrument rod (3). The handle (1) comprises a handle body (1.1) and a handle head (1.2), an outer conical face (1.2.1) is arranged on the front portion of the handle head (1.2), an external thread (1.2.3) is arranged on the rear portion of the handle head (1.2), a contraction groove (1.2.2) of 0.2mm in width is formed in the rear portion of the handle head (1.2), an internal thread (2.4) and an inner conical face (2.3) are arranged on the rear portion of the locking sleeve (2), a first instrument rod inserting hole (2.2) is formed in front of the inner conical face (2.3), second instrument rod inserting holes are formed in the handle head (1.2) and the front portion of the handle body (1.1), and the instrument rod (3) comprises a connection portion (3.1), a conical rod (3.2) and a working head. One-handle multi-head structure of the instrument can meet more clinical needs, so that energy consumption is lowered; enhancing of a central force bearing point is conducive to improving treatment accuracy.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and relates to an instrument for ear surgery, in particular to a detachable ear surgery instrument. Background technique [0002] In the otology outpatient surgery, or in the otology outpatient clinic for dressing changes and postoperative treatment, various instruments such as tympanic membrane spoons, cotton rolls, and tympanic membrane knives are needed. However, the following problems generally exist in these existing devices: 1. The head, rod, and handle are non-detachable structures welded together. Straight rod structure, the whole body diameter is 1-1.2mm, or a hollow tube with a diameter of 2mm, the central stress point is not strong enough, it is easy to produce elasticity, and it will hurt the non-treatment parts, resulting in reduced treatment accuracy. [0003] In view of the above-mentioned technical defects of the prior art, it is urgent to develop a novel detachable e...
