CN203017034U - Improved structure of nasal septum rongeur - Google Patents

Abstract

The utility model relates to a medical operative instrument, in particular to an improved structure of a nasal septum rongeur, and aims at solving the problems of deviations of a perpendicular plate of the ethmoid bone at the upper end and other operative dead angles can not be effectively cut off through utilization of an existing nasal septum rongeur. The nasal septum rongeur is formed by hand shanks and rongeur heads. The front end of each rongeur head is oblique and extends upwards to form an oblique portion. The included angle between the oblique portions and the horizontal plane is at least 40 degrees. The oblique portions at the front ends of the rongeur heads can easily reach a treatment site, can be used for effectively cutting off the deviations of the perpendicular plate of the ethmoid bone at the upper end and other operative dead angles, and enables treatment of the deviation of the nasal septum to be thorough and effective.

Description

The structural improvement of nasal septum cutting forceps

Technical field

This utility model relates to a kind of medical surgical instrument, especially a kind of structural improvement of nasal septum cutting forceps.

Background technology

At present, in existing nasal septum cutting forceps, the basic structure of its binding clip is: the identical involutory cup-shaped binding clip in both sides.This nasal septum cutting forceps by the involutory effect of both sides binding clip to septonasal sclerotin or cartilage, causes the fracture of sclerotin or cartilage in operation process, after fracture, sclerotin or the cartilage of fracture are removed.Yet, because front end and the horizontal plane of this kind nasal septum cutting forceps is parallel construction, therefore, can't effectively excises the partially bent operation such as grade of the lamina mediana dead angle of upper end, thereby affect treatment effect, the problem that lowers efficiency.

Summary of the invention

For the weak point of above-mentioned technology, this utility model provides a kind of can easily arrive the position that needs treatment, can effectively excise the partially bent structural improvement that waits the nasal septum cutting forceps at the dead angle of performing the operation of lamina mediana of upper end.

For achieving the above object, this utility model provides a kind of structural improvement of nasal septum cutting forceps, is made of handle and binding clip, and the front end face of described binding clip is skewed its and extends to form upward rake, and described rake and horizontal plane form the angle of at least 40 °.

Compared with prior art, the utlity model has following advantage:

This utility model is skewed its by the front end face with binding clip and extends to form upward rake, and form the angle of at least 40 ° with horizontal plane, can easily arrive the position that needs treatment, can effectively excise the partially bent dead angle of performing the operation of waiting of lamina mediana of upper end, make the deviation of nasal septum treatment more thorough, more effective.

Description of drawings

Fig. 1 is example structure figure of the present utility model;

Fig. 2 is the side-looking enlarged drawing of binding clip in Fig. 1.

Main symbol description is as follows:

1-handle 2-binding clip

3-rake 4-horizontal plane

The specific embodiment

Below in conjunction with drawings and Examples, this utility model is described in further detail.

As Fig. 1 and shown in Figure 2, this nasal septum cutting forceps is made of handle 1 and binding clip 2, and the front end face of binding clip 2 is skewed its and extends to form upward rake 3, and this rake 3 forms the angle of 40 ° with horizontal plane 4.

The above is only preferred embodiment of the present utility model, and is in order to limit this utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.

Claims (1)

1. the structural improvement of a nasal septum cutting forceps, be made of handle and binding clip, it is characterized in that, the front end face of described binding clip is skewed its and extends to form upward rake, and described rake and horizontal plane form the angle of at least 40 °.
