Description
Technical field
This utility model belongs to field of medical equipment technology, is specifically related to a kind of department of stomatology root canal irrigation device.
Background technology
Root canal therapy, also known as endodontic treatment, is the one operation for the treatment of pulp necrosis and tooth root infection in Oral Science.This operation remains tooth, thus complementary with extraction.
Root canal irrigation device is one of conventional medical apparatus and instruments in root canal therapy, and flushing tool conventional is at present common needles formula syringe, and the flushing dynamics that this flushing tool produces is little, is difficult to reach the object of rinsing whole root canal system completely.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides a kind of and rinses great efforts, rinses the device of department of stomatology root canal irrigation thoroughly.
The purpose of this utility model is achieved through the following technical solutions.
A kind of department of stomatology root canal irrigation device, the bending tube comprising needle holder and be connected with needle holder, described bending tube comprises horizontal tube and probes into pipe, described horizontal tube and the angle probeing into pipe are obtuse angle, the described tube wall probeing into pipe is provided with some areoles, the rear end of described needle holder is connected with horizontal tube by fastening bolt, described fastening bolt is connected with bracelet by bracing wire, the front end of described needle holder is provided with bellmouth, described bellmouth is communicated with the gas-liquid mixed chamber being arranged on needle holder rear end by spout, the sidewall of described needle holder is provided with the air inlet be communicated with gas-liquid mixed chamber, described gas-liquid mixed chamber is connected with horizontal tube by the room of slowing down of its rear end.
The further technical scheme of this utility model is: described in slow down room inner chamber be horn-like.
This utility model further technical scheme is: described air inlet is cylindrical hole.
The beneficial effect that this utility model produces owing to taking above-mentioned technological means is: department of stomatology root canal irrigation device of the present utility model, by arranging bellmouth in needle holder, flushing liquor flow velocity after bellmouth is accelerated, from spout injection at a high speed, its exit defines negative pressure due to high-speed liquid stream, sucks a small amount of air from the air inlet communicated with air, forms biphase gas and liquid flow in gas-liquid mixed chamber, flow velocity is higher, thus has and larger wash away strength.
Accompanying drawing explanation
Fig. 1 is the structural representation of department of stomatology root canal irrigation device of the present utility model.
In figure, 1-needle holder, 2-bellmouth, 3-air inlet, 4-spout, 5-gas-liquid mixed chamber, 6-slows down room, 7-fastening bolt, 8-bracing wire, 9-bracelet, 10-horizontal tube, and 11-probes into pipe, 12-areole.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain this utility model, and be not used in restriction this utility model.
Department of stomatology root canal irrigation device of the present utility model as shown in Figure 1, the bending tube comprising needle holder 1 and be connected with needle holder 1, this bending tube comprises horizontal tube 10 and probes into pipe 11, horizontal tube 10 and the angle probeing into pipe 11 are obtuse angle, the tube wall probeing into pipe 11 is provided with some areoles 12, the rear end of needle holder 1 is connected with horizontal tube 10 by fastening bolt 7, fastening bolt 7 is connected with bracelet 9 by bracing wire 8, the front end of needle holder 1 is provided with bellmouth 2, bellmouth 2 is communicated with the gas-liquid mixed chamber 5 being arranged on needle holder 1 rear end by spout 4, the sidewall of needle holder 1 is provided with the air inlet 3 be communicated with gas-liquid mixed chamber 5, air inlet 3 is cylindrical hole, gas-liquid mixed chamber 5 is connected with horizontal tube 10 by the room 6 of slowing down of its rear end, the inner chamber slowing down room 6 is horn-like.
Department of stomatology root canal irrigation device of the present utility model, when flushing liquor is by bellmouth 2, fluid pressure increases, and flow velocity is accelerated; Flushing liquor is from spout 4 injection at a high speed, its exit defines negative pressure due to high-speed liquid stream, a certain amount of air is sucked from the air inlet 3 communicated with air, gas-liquid mixed chamber 5 is entered together with liquid stream, gas, water Homogeneous phase mixing in hybrid chamber, form biphase gas and liquid flow, its volumetric ratio single-phase water greatly increases, thus makes up because liquid inlet volume reduces the volume deficiency brought; At this moment mixed biphase gas and liquid flow also has higher flow velocity, after slowing down room 6 injection, go out through probeing into the areole 12 of pipe 11, its two phase flow has larger than single-phase water flow volume, flow velocity is higher, thus have and larger wash away strength, thus reach the object of saving flushing liquor and improving flushing ability.
The above embodiment only have expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
