Problems solved by technology

It is precisely because of the development of this type of new surgery that the original surgical instruments cannot meet the needs of clinicians, especially when exposing the deep surgical field of view, there is no effective nasal spreader
The existing nasal septum distractor and the nasal cavity distractor are independent, and the two are not compatible with each other, that is, the existing nasal septum distractor cannot be used to expose the deep part of the nasal cavity, and the nasal septum distractor cannot be used for the operation field of the nasal septum (referring to the surgical field). as far as the eye can see) to provide effective exposure
In addition, none of the existing nasal spreaders has a suction device

Embodiment Construction

[0015] see figure 1 , 2 , nasal cavity, nasal septum double-position spreader, mainly composed of left and right forceps, corresponding support leaves 1, 2 and gear support device, the shape of left and right forceps is symmetrically connected by forceps shaft 12, and the forceps body is divided into front part by forceps shaft 12 The support arms 5, 6 and the pliers handles 3, 4 at the rear are two parts, the support arms 5, 6 are arc-shaped, the front parts of the support arms 5, 6 shrink inward, and the rear parts protrude outward in an "S" shape . see image 3 , Fig. 4, the support arms 5,6 are bent upwards from the rear protrusions to form upturned front sections 51,61 and horizontal rear sections 52,62. The included angle is α, and the size of α is 25-35 degrees. The front ends of the front sections 51, 61 are respectively provided with willow-shaped support leaves 1, 2 with narrow ends and wide head ends. The angle is β, and the size of β is 90-95 degrees. The ends...

Abstract

The invention discloses a nasal cavity, nasal septum double-site spreader capable of fully exposing the nasal cavity deep surgery field and effectively exposing the nasal septum surgery field, mainly formed by connecting the symmetrical left, right pliers by the tongs axle and a supporting arm at the front part of the tongs is arc and the front part of the supporting arm contracts inwards and the back part of the supporting arm projects outwards in S shape and the supporting arm bends upwards from the back projection part to form an upwarping forepart and a horizontal backpart and supporting leaves are respectively set on the front end of the forepart and the supporting leaves are set above the forepart and the ends of the supporting leaves point to the symmetric center lines of the left, right tongs. The nasal cavity, nasal septum double-site spreader is capable of fully exposing the nasal cavity deep surgery field and effectively exposing the nasal septum surgery field. The suction catheters can quickly suck the effusion and effused blood to ensure the deep surgery field clear, thereby providing the operation space and visual field for the clinical operation. In addition, the used gear positioning device has features of firm structure and convenient operation.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a nasal cavity and nasal septum double-position spreader. Background technique [0002] Rhinonasal sinus diseases are common and frequently-occurring diseases in clinic, and surgical treatment is one of the main means to solve such diseases. With the wide application of new technologies and the development of medical technology, nasal cavity and sinus surgery has made a qualitative leap, especially the application of microscopic technology and nasal endoscopic technology, which has gradually expanded the scope of nasal surgery from the nasal cavity and sinuses to the front. Skull base around the orbital and other tissue parts. It is precisely because of the development of this type of new operation that the original surgical instruments cannot meet the needs of clinicians, especially when exposing the deep surgical field of view, there is a lack of effective nasal spreader. The existing...
