Description
Technical field
The present invention relates to medical instruments field, specially a kind of novel Doppler probe.
Background technology
In hemorrhoid treating technology, doppler transducer needs to find hemorrhoid arteries and hemorrhoid arteries is ligatured,
Suture suspention is carried out to hemorrhoid body after the completion of ligation.Transducer in doppler transducer is fixed by gluing, is reached by shutting
To the effect of sealing, once minor issue occurs in probe, can not dismantle to analyze failure, probe can not check and
Maintenance, can only typically select to change whole probe segment, not only increase cost, and bring many fiber crops to control
It is tired.
The content of the invention
It is an object of the invention to provide a kind of novel Doppler probe, easy disassembly, reduces the cost changed and safeguarded.
To achieve these goals, the technical scheme used for：A kind of novel Doppler probe, including sleeve pipe and housing,
It is provided with piezoelectrics in described sleeve pipe, the ripples of piezoelectrics generating surface of shaking is bonded with the shell bottom surface of housing, and the ripple of the piezoelectrics shakes
Film body is folded between generating surface and shell bottom surface, screw thread is respectively arranged with the periphery wall of described sleeve pipe and the inwall of housing
Section, is provided with annular lug on sleeve pipe on the rear end outer wall in precession direction, set on the housing in the front inner wall in precession direction
It is equipped with annular groove.
Compared with prior art, technique effect of the invention is：Measured one's own ability by applying so that annular lug is recessed across annular
After the cell wall of groove, annular lug is located at the position that housing axial direction is limited in the vallecular cavity of annular groove；In dismounting, apply excessive
External force, make radial direction deformation at annular groove on housing, so that cell wall of the annular lug across annular groove, continues convolution completion and tear open
Unload, sleeve pipe and housing cooperation are solid and reliable, simple in construction, and operating personnel are very quick in dismounting.
Brief description of the drawings
Fig. 1 is the schematic diagram after the present invention is split；
Fig. 2 is schematic diagram overall after the present invention assembles.
Embodiment
The present invention is described in further detail with reference to Fig. 1 and 2.
A kind of novel Doppler is popped one's head in, including sleeve pipe 10 and housing 20, and piezoelectrics 30, piezoelectricity are provided with described sleeve pipe 10
The ripple of body 30 generating surface of shaking is bonded with the shell bottom surface 22 of housing 20, and the ripple of the piezoelectrics 30 shakes between generating surface and shell bottom surface 22
Film body 40 is folded with, thread segment is respectively arranged with the periphery wall of described sleeve pipe 10 and the inwall of housing 20, is revolved on sleeve pipe 10
Enter on the rear end outer wall in direction to be provided with annular lug 11, annular is provided with the front inner wall in precession direction on the housing 20
Groove 21.
In such scheme, when mounted, by the precession into precession housing 20 of sleeve pipe 10, application is measured one's own ability so that annular lug 11
Across after the cell wall of annular groove 21, annular lug 11 is located at the position that the axial direction of housing 20 is limited in the vallecular cavity of annular groove 21；
In dismounting, apply excessive external force, make radial direction deformation at annular groove 21 on housing 20, so that annular lug 11 is across annular
The cell wall of groove 21, continue convolution and complete dismounting, sleeve pipe 10 and housing 20 coordinate solid and reliable, and simple in construction, operating personnel exist
It is very quick during dismounting.Film body 40 is one layer of flexible glue layer, and the ripple that the flexible glue is evenly coated in piezoelectrics 30 shakes generating surface and shell bottom
On face 22 so that the ripple of piezoelectrics 30 shakes generating surface and shell bottom surface 22 realize it is seamless be bonded, piezoelectrics 30 can be without hindrance
Launch ultrasonic wave with hindering, prevent piezoelectrics 30 from vibratory impulse phenomenon occurs with shell bottom surface 22, extend the use of doppler transducer
Life-span.
The piezoelectrics 30 are connected with base 31, and the inwall of described sleeve pipe 10 is in step-like and in the anterior pipe in precession direction
Internal diameter is more than the internal diameter of trailing spigot 10, the inwall of described sleeve pipe 10 precession direction anterior diameter and piezoelectrics 30 it is straight
Footpath is consistent, and the diameter of the inwall of described sleeve pipe 10 at the rear portion in precession direction is consistent with the diameter of base 31.Ensure piezoelectrics 30
It can in the axial direction be securely fixed, ensure that piezoelectrics 30 can stably launch ultrasonic wave.
The groove 21 is dovetail groove, on the groove 21 between the cell wall 211 and the tube wall of housing 20 of precession direction front end
Offer interior chamfering 23.Prevent damage recess 21 or projection 11, ensure ring-type projection 11 smoothly across.
The bottom of described sleeve pipe 10 offers through hole 12, and the through hole 12 passes through for the wire on base 31.
The through hole 12 is the reducing hole that the medial aperture of sleeve pipe 10 is big, outside aperture is small.Facilitate the wire energy on base 31
Enough pass rapidly through.
The preferred embodiment of the present invention described in detail above, but the present invention is not limited in above-mentioned embodiment
Detail, in the range of the technology design of the present invention, a variety of equivalents can be carried out to technical scheme, these
Equivalents belong to protection scope of the present invention.
