The further technical scheme of this utility model is: described staight shank drilling rod is provided with the gimbal lever, and the described gimbal lever is connected with spacing arched arm by spring.
This utility model further technical scheme is: described sleeve pipe is elliposoidal pipe.
This utility model further technical scheme is: described cutting edge is made up of titanium sintered material.
The beneficial effect that this utility model produces owing to taking above-mentioned technological means is: surgery bone drilling hole of the present utility model device, by arranging bellmouth in staight shank drilling rod, 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, a small amount of air is sucked from the air inlet communicated with air, biphase gas and liquid flow is formed in gas-liquid mixed chamber, flow velocity is higher, biphase gas and liquid flow, after the coarctation segment through direct-connected pipe, further increases flow velocity.And the caliber at elliposoidal sleeve pipe rear portion reduces gradually, while increase flow velocity, increase pressure, thus have and larger wash away strength.
Accompanying drawing explanation
Fig. 1 is the structural representation of the first embodiment of surgery bone drilling hole of the present utility model device.
Fig. 2 is the structural representation of the second embodiment of surgery bone drilling hole of the present utility model device.
In figure, 1-staight shank drilling rod, 2-adapter sleeve, 3-bellmouth, 4-air inlet, 5-spray orifice, 6-gas-liquid mixed chamber, 7-cushion chamber, the direct-connected pipe of 8-, the 9-gimbal lever, 10-spring, the spacing arched arm of 11-, 12-bearing, 13-drill headstock, 14-loose rib, 15-drill bit, 16-cutting edge, 17-coarctation segment, 18-sleeve pipe, 19-intercommunicating pore.
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.
The first embodiment of surgery bone drilling hole of the present utility model device as shown in Figure 1, this borer comprises staight shank drilling rod 1, drill bit 15 and drill headstock 13, the outer wall of drill bit 15 is provided with cutting edge 16, cutting edge 16 can be made up of titanium sintered material, the lower end of drill bit 15 is socketed in the lower end of staight shank drilling rod 1, the upper end interlocking of this drill bit 15 is in drill headstock 13, bearing 12 is provided with between drill headstock 13 and staight shank drilling rod 1, the upside of bearing 12 is provided with loose rib 14, and bearing 12 is sealed in drill headstock 13 by loose rib 14; Staight shank drilling rod 1 is provided with adapter sleeve 2, adapter sleeve 2 is for connecting irrigating syringe, the front end of staight shank drilling rod 1 is provided with bellmouth 3, bellmouth 3 is communicated with the gas-liquid mixed chamber 6 be arranged in staight shank drilling rod 1 by spray orifice 5, the sidewall of staight shank drilling rod 1 is provided with the air inlet 4 be communicated with gas-liquid mixed chamber 6, gas-liquid mixed chamber 6 is connected with the direct-connected pipe 8 be arranged in staight shank drilling rod 1 by the cushion chamber 7 of its rear end; Direct-connected pipe 8 overcoat has sleeve pipe 18, and sleeve pipe 18 is preferably elliposoidal pipe, and the end of direct-connected pipe 8 is the coarctation segment 17 stretching into sleeve pipe 18, and sleeve pipe 18 is connected with the intercommunicating pore 19 being arranged on drill bit 15 top; Adapter sleeve 2, bellmouth 3, spray orifice 6, gas-liquid mixed chamber 6, cushion chamber 7, direct-connected pipe 8 and sleeve pipe 18 are communicated with into the feed pathway that is positioned at staight shank drilling rod 1 successively.
Fig. 2 is the structural representation of the second embodiment of surgery bone drilling hole of the present utility model device, as depicted in figs. 1 and 2, be with the difference of the first embodiment, staight shank drilling rod 1 be provided with the gimbal lever 9, the gimbal lever 9 is connected with spacing arched arm 11 by spring 10.
Surgery bone drilling hole of the present utility model device, after connecting irrigating syringe by adapter sleeve 2, when pushing syringe makes flushing liquor by bellmouth 3, fluid pressure increases, and flow velocity is accelerated; Flushing liquor is from spray orifice 5 injection at a high speed, the exit of spray orifice 5 defines negative pressure due to high-speed liquid stream, a certain amount of air is sucked from the air inlet 4 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, and gas-liquid two-phase further increases flow velocity after flowing through the coarctation segment 17 of direct-connected pipe 8.And the caliber at elliposoidal sleeve pipe 18 rear portion reduces gradually, while increase flow velocity, increase pressure, thus have and larger wash away strength, reach the object of saving flushing liquor and improving flushing ability.This surgery bone drilling hole device can rinse while boring, and rinses great efforts, flushing thoroughly, thoroughly can clean surgical field of view.
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.
