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 expanding needle apparatus.
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 complements one another with extraction, and especially for the patient having exodontia contraindication, root canal is particularly important.
Reamer is one of conventional medical apparatus and instruments in root canal therapy, and existing reamer both can use as expansion root pipe, also can connect syringe to injection through root canal medicine or flushing liquor after expansion root pipe.But flushing tool conventional is at present common needles formula syringe, 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 department of stomatology root-canal expanding needle apparatus thoroughly.
The purpose of this utility model is achieved through the following technical solutions.
A kind of department of stomatology root-canal expanding needle apparatus, comprise base handle, fastener and expansion pin, described base handle is connected with expansion pin by fastener, the working end of described expansion pin is a nook closing member, the outer wall of described nook closing member is provided with helical edges, described base handle, the central authorities of fastener and expansion pin are provided with a through hole, described base handle is provided with adapter sleeve, the front end of described base handle is provided with bellmouth, described bellmouth is communicated with the gas-liquid mixed chamber being arranged on base handle rear end by spray orifice, the sidewall of described base handle is provided with the air inlet be communicated with gas-liquid mixed chamber, described gas-liquid mixed chamber is connected with through hole by the room of slowing down of its rear end.
The further technical scheme of this utility model is: described air inlet is cylindrical hole or slotted eye.
This utility model further technical scheme is: described helical edges is made up of titanium alloy material.
The beneficial effect that this utility model produces owing to taking above-mentioned technological means is: department of stomatology root-canal expanding needle apparatus of the present utility model, by arranging bellmouth in base handle, flushing liquor flow velocity after bellmouth is accelerated, from spray orifice injection at a high speed, the exit of spray orifice 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 expanding needle apparatus of the present utility model.
In figure, 1-base handle, 2-adapter sleeve, 3-bellmouth, 4-spray orifice, 5-air inlet, 6-gas-liquid mixed chamber, 7-slows down room, 8-fastener, and 9-expands pin, 10-nook closing member, 11-through hole, 12-helical edges.
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 expanding needle apparatus of the present utility model as shown in Figure 1, comprise base handle 1, fastener 8 and expansion pin 9, base handle 1 is connected with expansion pin 9 by fastener 8, the working end expanding pin 9 is a nook closing member 10, the outer wall of nook closing member 10 is provided with helical edges 12, helical edges 12 can be made up of titanium alloy material, base handle 1, the central authorities of fastener 8 and expansion pin 9 are provided with a through hole 11, base handle 1 is provided with adapter sleeve 2, adapter sleeve 2 can be connected on irrigating syringe, the front end of base handle 1 is provided with bellmouth 3, bellmouth 3 is communicated with the gas-liquid mixed chamber 6 being arranged on base handle 1 rear end by spray orifice 4, the sidewall of base handle 1 is provided with the air inlet 5 be communicated with gas-liquid mixed chamber 6, air inlet 5 can be cylindrical hole or slotted eye, gas-liquid mixed chamber 6 is connected with through hole 11 by the room 7 of slowing down of its rear end.
Department of stomatology root-canal expanding needle apparatus of the present utility model, after adapter sleeve 2 connects irrigating syringe, when pushing syringe makes flushing liquor by bellmouth 3, fluid pressure increases, and flow velocity is accelerated; Flushing liquor is from spray orifice 4 injection at a high speed, the exit of spray orifice 4 defines negative pressure due to high-speed liquid stream, a certain amount of air is sucked from the air inlet 5 communicated with air, gas-liquid mixed chamber 6 is entered together with liquid stream, gas, liquid Homogeneous phase mixing in hybrid chamber, form biphase gas and liquid flow, its volumetric ratio single-phase liquid 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 7 injection, go out through through hole 11, its two phase flow has the feature larger than single-phase water flow volume, flow velocity is higher, thus have and larger wash away strength, 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.
