Abstract

The utility model provides a hard adventitia supersound puncture positioner, including pjncture needle (2), ultrasonic probe (1), display screen (4), ultrasonic probe (1) sets up the syringe needle end at pjncture needle (2), and (4) are connected through supersound wire (3) in ultrasonic probe (1) with the display screen, it is inside that supersound wire (3) are located hollow pjncture needle (2). The utility model discloses introduce the dura mater in -process that punctures outward with ultrasonic device, it is visual that the advantage that combines supersound visualization technology will rely on the dura mater technique of puncturing that the experience felt originally outward, to difficulty puncture patient, provides best puncture pathway, instructs the anesthetist to puncture, avoids the damage, reduces because of the location repeatedly that blind spy operation brought, punctures repeatedly, reduces the puncture mistake and go into blood vessel and cavum subarachnoidale probability. Reduce patient's physiology and psychological wound.

Description

A kind of hard adventitia ultrasonic puncture positioner

Technical field

This utility model is a kind of epidural ultrasonic puncture positioner, can visit operation visualization by blind, be particularly suited for back obese patient, it is impossible to location intervertebral space patient, and difficulty punctures patient etc.

Background technology

In clinical anesthesia, epidural puncture art is one of the technical ability that must grasp of a qualified Anesthetist, is also one of main embodiment of modern anesthesia. Generally, patient-side clinostatism can expose spinal column after going down on one's knees preferably, thus facilitating Anesthetist to position, punctures. But visit operation owing to epidural puncture belongs to blind, the full experience with Anesthetist and feel, some patients is likely to be due to back fat accumulation in addition, intervertebral space location difficulty, puncture the reasons such as difficulty and cause puncture failure, or occurring unnecessary damage and related complication in piercing process, the physiology to patient, psychology causes damage.

Utility model content

For solving the thorny problem run in clinical anesthesia implementation process, Vltrasonic device is introduced in epidural puncture process by this utility model, the epidural puncture technology of script feel by rule of thumb is visualized by the advantage in conjunction with ultrasonic visualization technology, thus reduce in anesthetic puncture process it is possible that complication, and part puncture difficulty patient is played guidance puncture, it is to avoid the effect of damage.

It is as follows that this utility model solves the technical scheme that its technical problem adopts:

A kind of hard adventitia ultrasonic puncture positioner, including puncture needle (2), ultrasonic probe (1), display screen (4); Ultrasonic probe (1) is arranged on the needle end of puncture needle (2), and ultrasonic probe (1) is connected with display screen (4) by ultrasonic wire (3).

The puncture needle (2) that described ultrasonic wire (3) is positioned at hollow is internal.

Described ultrasonic probe (1) and puncture needle (2) have two kinds of set-up modes, and one is to be flexibly connected, a kind of

It it is non-flexible connection.

This utility model utilizes ultrasonic visualization device, it is introduced in epidural puncture process, for planning to implement the patient of epidural puncture, is accurately positioned intervertebral space by ultrasonic probe, biopsy needle guide inserting needle direction, thus avoiding the occurrence of unnecessary damage and related complication.

The beneficial effects of the utility model:

Under the guiding of ultrasonic visualization technology, puncturing patient for difficulty, it is provided that best puncture pathway, instruct Anesthetist to puncture, it is to avoid damage, reduce and visit the location repeatedly that operation brings, repeated localised puncture because of blind, minimizing puncture is strayed into blood vessel and subarachnoid space probability. Reduce the wound of patient's physiology and psychology.

Accompanying drawing explanation

Fig. 1 is structure diagram of the present utility model (ultrasonic probe is inactive with puncture needle to be connected);

Fig. 2 is structure diagram of the present utility model (ultrasonic probe is flexibly connected with puncture needle);

Wherein, 1 ultrasonic probe, 2 puncture needles, 3 ultrasonic wire, 4 display screens.

Detailed description of the invention

Below in conjunction with drawings and Examples, this utility model is described further.

This utility model includes puncture needle (2), ultrasonic probe (1), display screen (4); Ultrasonic probe (1) is arranged on the needle end of puncture needle (2), and ultrasonic probe (1) is connected with display screen (4) by ultrasonic wire (3).

Described ultrasonic probe (1) and puncture needle (2) have two kinds of set-up modes, one is to be flexibly connected, as in figure 2 it is shown, when using, patient-side clinostatism go down on one's knees after sterile drape, local infiltration anesthesia, after the anesthesia spinal needle of hollow is slowly entered patient's intervertebral space, more slowly inserts ultrasonic probe from puncture needle, according to ultrasonic image guided puncture, adjust inserting needle direction, it is determined that position, enter epidural space. Another kind is non-flexible connection, as it is shown in figure 1, patient-side clinostatism go down on one's knees after sterile drape, after local infiltration anesthesia, with the anesthesia spinal needle (2) of ultrasonic probe (1), front end is slowly entered patient's intervertebral space, and under the guiding of ultrasonoscopy, localised puncture enters epidural space on a display screen.

Claims

1. a hard adventitia ultrasonic puncture positioner, it is characterised in that: include puncture needle (2), ultrasonic probe (1), display screen (4); Ultrasonic probe (1) is arranged on the needle end of puncture needle (2), and ultrasonic probe (1) is connected with display screen (4) by ultrasonic wire (3); The puncture needle (2) that described ultrasonic wire (3) is positioned at hollow is internal; Described ultrasonic probe (1) and puncture needle (2) have two kinds of set-up modes, and one is to be flexibly connected, and one is non-flexible connection.
