Abstract

A temporal-mandibular joint ultrasonic probe through an external auditory canal comprises a probe body (2) and a probe handle (3). The temporal-mandibular joint ultrasonic probe is characterized in that the probe body (2) is columnar, the outer diameter of the probe body is in socketed fit with the diameter of the external auditory canal of a human ear, and the length of the probe body is 30-50% of that of the external auditory canal. The temporal-mandibular joint ultrasonic probe has the advantages that the ultrasonic probe can be inserted into the external auditory canal of an examinee, and only a layer of cartilage exists between the external auditory canal and a condyle process, so that bone tissue reflection can be reduced substantially, most ultrasonic waves enter a deep structure of a temporal-mandibular joint, images are clearer, and diagnosis rate of temporal-mandibular joint diseases is increased remarkably.

Description

Through external auditory meatus remporomandibular joint ultrasonic probe

Technical field

This utility model relates to a kind of medical apparatus and instruments, a kind of through external auditory meatus remporomandibular joint ultrasonic probe.

Background technology

Remporomandibular joint ultrasonic examination is the routine examination of temporomandibular arthrosis diagnosis, and device therefor is a kind of high-resolution ultrasound probe that approaches hand size.During inspection, probe is placed in those who are investigated's the prominent outside of tragus preartis, and zygomatic arch below, is horizontal shape face and contacts with outer skin respectively with sagittal plane, and ultrasound wave passes the little gap between glenoid fossa and condyle bone, and obtains ultrasonoscopy.Because probe and check point are distant, ultrasound wave need to penetrate multilayer tissue, and most of ultrasound wave is reflected, and only surplus sub-fraction enters DEEP STRUCTURE, thereby image effect is poor, and diagnosis difficulty is larger.

Summary of the invention

The purpose of this utility model is to provide a kind of probe and check point close together, and organizing of interval is less, and middle osseous tissue reflection is lower, the clear picture that obtains, the remporomandibular joint ultrasonic probe that diagnosis difficulty reduces.

Above-mentioned purpose is realized by following technical scheme: develop a kind of through external auditory meatus remporomandibular joint ultrasonic probe, comprise probe and probe handle, be characterized in: described probe is column, its external diameter coordinates for pegging graft with the external auditory meatus diameter of people's ear, and its length is the 0.3-0.5 of external auditory meatus length.

The external diameter of described probe is 8-18mm, and length is 7.5-13mm.

Described probe is arranged on the front end of the probe handle of tubulose.

Described probe handle is the handle of bending.

Described probe handle is the handle of bending, the semicircular elasticity link matching is installed after handle with people's head.

Described probe handle is the ear-hang ring matching with people's auricle root periphery.

Described probe handle in the form of a ring.

The beneficial effects of the utility model are: this ultrasound probe can insert those who are investigated's external auditory meatus, external auditory meatus alternating floor cartilage only between condyle is prominent, can significantly reduce osseous tissue reflection, most of ultrasound wave enters remporomandibular joint DEEP STRUCTURE, image is more clear, and the diagnosis of temporomandibular arthrosis significantly improves.

The specific embodiment

The total design of this utility model is the remporomandibular joint ultrasonic probe that the deep enough people's of a kind of energy of development external auditory meatus is obtained picture signal.Below in conjunction with accompanying drawing, introduce five kinds of embodiment:

The first embodiment: as shown in Fig. 1 Fig. 2, the critical piece of this remporomandibular joint ultrasonic probe 1 has probe 2, probe handle 3 and wire 4, is connected with display screen by wire 4.This remporomandibular joint ultrasonic probe 1 claims again supersonic generator or receptor, to utilize the quartzy piezoelectric effect of piezoquartz that waits to convert electrical energy into Under Ultrasonic Vibration kinetic energy, or Under Ultrasonic Vibration kinetic energy is converted to a kind of device of electric energy, can play the effect of ultrasonic emitting and reception.As required, remporomandibular joint inspection should adopt high-resolution high frequency probe.The main feature of the remporomandibular joint ultrasonic probe that this is routine is: its probe 2 is column, and its external diameter coordinates for pegging graft with the external auditory meatus diameter of people's ear, and its length is the 0.3-0.5 of external auditory meatus length.Certainly, said column can be cylinder here, circular cone post, sphere post etc.

In general, people's external auditory meatus diameter is 8-18mm, and the degree of depth is in 25mm, and therefore, the external diameter of this probe is elected 8-18mm as, and length is 7.5-13mm, also can make respectively the product of large, medium and small three kinds of models.

As seen from Figure 1, probe 2 is arranged on the front end of the probe handle 3 of tubulose.Certainly, the shape of probe handle 3 can be diversified, and the probe handle 3 of recommending is here a kind of handles 5 that are suitable for manual bending.During use, as shown in Figure 3, probe 2 is inserted to those who are investigated's external auditory meatus, twisting handle 5, dehisces or obtains the remporomandibular joint image of Static and dynamic during closed mouth position those who are investigated.

The second embodiment: as shown in Figure 4, this ultrasound probe 1 is also comprised of probe 2, probe handle 3 and wire 4 etc., is connected with display screen by wire 4.At probe handle 3, be also the handle of bending, the semicircular elasticity link 6 matching be installed after handle with people's head.During use, as shown in Figure 5, link 6 is clipped in to people's head, probe 2 inserts people's external auditory meatus, uses convenient.

The third embodiment: as shown in Fig. 6 Fig. 7, this remporomandibular joint ultrasonic probe 1 is also comprised of probe 2, probe handle 3 and wire 4 etc., is connected with display screen by wire 4.Be characterized in: probe handle 3 is the ear-hang rings 7 that match with people's auricle root periphery.During use, after probe 2 is inserted to people's external auditory meatus, its ear-hang ring 7 is taken advantage of a situation and is hung over people's auricle outside, more convenient to operate.

The 4th kind of embodiment: as shown in Figure 8, whole remporomandibular joint ultrasonic probe 1 shape is as the earplug of earphone, and probe handle 3 is a bit of cylinders.This relatively simple for structure, after probe 2 insertion people's external auditory meatus, as long as twisting probe handle 3, probe 2 is swingable and collection image.

The 5th kind of embodiment: as shown in Figure 9, this remporomandibular joint ultrasonic probe 1 is also comprised of probe 2, probe handle 3 and wire 4 etc., is connected with display screen by wire 4.Be characterized in: probe handle 3 in the form of a ring.When probe 2 inserts external auditory meatus, its ring-type probe handle 3 is enclosed within ear post around just, can avoid the obstruction of ear post to probe handle 3, more convenient to operate.
