Description
Technical field
The present invention relates to a kind of applied to ultrasonic examination or the probe capsule cap of guiding puncture, belongs to medical auxiliary instrument technology
Field.
Background technique
In recent years, Ultrasound-guided Biopsy is because its operational safety is high, site of puncture precisely becomes most of medical staff
First choice when puncture procedure is carried out, is clinical suitable for the biopsy drawing liquid of artery and vein puncture, nerve block and various superficial focis
Carry out the important technical of diagnosing and treating.
Clinical current operating method is after ultrasonic probe daubing coupling agent, will to be put into ultrasonic special sterile rubber sheath,
Sterile rubber sheath is tightened in detecting head surface, excludes bubble remaining between probe and rubber surface and couplant by hand, then is used
Sterile rubber sheath is fixed on probe by sterile rubber band winding.When operation, it can be applied in skin and sterile rubber sheath surface
Sterile couplant or disinfection solvent are smeared, medium, conducted acoustic waves are played the role of.
But the method for the prior art has following defects that 1, since the certain positions of body surface are prominent with bone, leads to part
The partially thin check object of body surface out-of-flatness, especially figure, ultrasonic probe can not be bonded completely with skin surface, lead to clinical inspection
Look into use, skin fail with probe fit area below there are image deletions.2, it since puncture procedure is sterile working, needs
Sterile working principle is followed strictly, easily causes sterile working difficult using couplant.By above-mentioned traditional application method, operating procedure
It is more, it is excessively cumbersome, it is easy to pollute in use.3, couplant is added in existing method in sterile sheath, needs manual row
Except the bubble in sheath, otherwise bubble will affect imaging.4, since detecting head surface is a rigid planar, it is difficult to for observing movement
In intra articular structure change, that is, move in joint, surface will form concave surface or convex surface, can not paste with detecting head surface
It closes.

Specific embodiment
Embodiment 1
For probe capsule cap of the invention as shown in Figure 1-3, including capsule cap shell 1, medium capsule 6 connects snare 3, buckles 4 and visits
Head protection set 5；The capsule cap shell 1 is hollow ring-shaped shell structure；1 underfill medium capsule 6 of capsule cap shell, makes outside capsule cap
Probe accommodating chamber 2 is formed at the hollow region top of shell 1；The medium capsule 6 is to be filled up completely sound wave conduction inside emulsion capsule to be situated between
The cystic structures formed after matter, the periphery of medium capsule 6 and the inner sidewall of capsule cap shell 1 are bonded and are fixed.
The probe capsule cap can high-temperature sterilization, reuse.Sound wave transmitting medium inside medium capsule 6 is liquid medium,
By going bubble technique, making medium, movement will not generate bubble in any way in medium capsule 6.The material of medium capsule 6 is
Soft latex can be sufficiently bonded with skin surface.Capsule cap shell is flexible, on-deformable rubber material.Its
6 periphery of medium capsule plays the role of that the volume of medium capsule 6 is fixed, and medium capsule 6 is made to be not easy when moving.The spy
Head accommodating chamber 2 is matched with the size of probe, can be according to the probe designs of different model at different sizes.The top of capsule cap shell 1
Face ring is around probe 2 periphery of accommodating chamber setting connection snare 3, for connecting capsule cap shell 1 and buckle 4.Connecting snare 3 can be with buckle
By bonding, suturing connection.Buckle 4 is symmetricly set on capsule cap shell 1, for capsule cap and the probe fixation of popping one's head in, makes to pop one's head in
It stretches in probe accommodating chamber 2, is sufficiently bonded with the bottom surface of probe accommodating chamber 2.Probe protective case 5 is connected with snare 3 is connect, can
It will be integrally wrapped in inside containing the probe including handle, realizes probe generally in germ-free condition.
Medium composition in medium capsule 6 is glycerine 5~10%, guar gum 1~3%, polyethylene glycol 2~8%, polyethylene
Pyrrolidones 2~12%, cross-linked polyacrylic resin 0.8~1.5%, surplus are water.Acoustic impedance about 1.5 × 106Pas/m,
The velocity of sound about 1500~1600m/s.Translucidus is good.
Application method of the invention are as follows: couplant is coated to probe 2 bottom surface of accommodating chamber, by detecting head surface and probe accommodating chamber
The fitting of 2 bottom surfaces, and fixed probe and probe capsule cap by buckle 4.In rotor working process, the bottom surface of medium capsule 6 can be with
Seamless applying skin.By the restriction of 1 inner sidewall rubber of capsule cap shell, when medium capsule 6 touches bone outburst area, bottom surface meeting
It deforms, the position contacted with outburst area is made to be recessed, 6 bottom surface of medium capsule is kept to be bonded contacted skin surface always.
The medium filled inside medium capsule 6 has stronger penetration capacity, is conducive to sound wave and conducts.Probe using effect of the invention is as schemed
Shown in 4, when in use, detecting head surface seamless can fit in patient body-surface position, the entrance of effective pre- air-prevention.Probe is protected
Probe entirety can be completely encapsulated in inside by sheath including handle, realize whole sterile working.Before being punctured and
In puncture process, the image of detection can accurately show the state of subcutaneous tissue, assist personnel accurate judgement puncture portion
Position, accurate adjustment puncture direction.
Reference examples 1
It is immersed in couplant using the couplant (shown in Fig. 5) of rubber sleeve package 1 same amount of embodiment, and by probe,
Probe is wrapped up and fixed with rubber sleeve, same position is detected using same way, as a result as shown in fig. 6, image
In show apparent bubble, be unfavorable for detect position identification.
Reference examples 2
Specific embodiment is with embodiment 1, difference, is glycerine 15%, guar gum by the composition adjustment of medium
5%, polyethylene glycol 2~8%, polyvinylpyrrolidone 1%, cross-linked polyacrylic resin 0.8~1.5%, surplus is water.Using
The couplant is detected as the probe of media filler, the easily-deformable abjection in the region of dielectric surface and skin contact, and is imaged
Ineffective (as shown in Figure 7 B), image is discontinuous, and occurs apparent artifact in image.And use the probe capsule of embodiment 1
The imaging clearly of cap can accurately show subcutaneous tissue state and joint space (Fig. 7 A).
Reference examples 3
With embodiment 1, difference is specific embodiment, does not carry out bubble to medium and handles, and medium is replaced
For common couplant.Probe using the couplant as media filler detects finger pulp and joint, as shown in Figure 8 B,
By aeration, crooked position imaging failure has the region of imaging also because of the reflective influence interpreting blueprints result of apparent bubble.And it uses
The probe capsule cap of embodiment 1, the crooked position of finger pulp are strictly bonded, imaging clearly (Fig. 8 A).
Reference examples 4
Commercially available couplant is wrapped up using rubber sleeve, and probe is immersed in couplant, is wrapped up probe and solid with rubber sleeve
It is fixed, thyroid gland areas is detected using 1 same way of embodiment, as a result as shown in Fig. 9 (9A and 9B), imaging effect is not
It is good, it is difficult to obtain clear, accurate image.
Although the present invention has been described by way of example and in terms of the preferred embodiments, it is not intended to limit the invention, any to be familiar with this skill
The people of art can do various change and modification, therefore protection model of the invention without departing from the spirit and scope of the present invention
Enclosing subject to the definition of the claims.
