Description
Technical Field
The utility model relates to the field of medical equipment, concretely relates to epidural puncture auxiliary device.
Background
Epidural anesthesia refers to epidural space block anesthesia, i.e., local anesthetic is injected into the epidural space to block spinal nerve root and temporarily paralyze the innervated area, which is called epidural space block anesthesia, or epidural space block for short. Depending on the mode of administration, a single-dose method and a continuous method can be classified. The puncture position can be divided into high position, middle position, low position and sacral canal block. Theoretically, epidural blockage can be used for any procedure except for the head. But from a safety standpoint, epidural retention is mainly used in abdominal and following operations, including urological, gynecological, caesarean and lower limb operations. The neck, upper limbs and chest are applicable, but the management is complicated. The high-level epidural is mainly used for postoperative analgesia or general anesthesia composite epidural anesthesia so as to reduce the dosage of general anesthesia. In addition, epidural block anesthesia can be used for subarachnoid block surgery. It can also be used for postoperative analgesia.
At present, the puncture body positions comprise a lateral position and a sitting position, and the lateral position is mainly adopted clinically. The puncture point should be selected according to the surgical site, generally taking the corresponding interspinous space that governs the center of the surgical field. Epidural space puncture includes two kinds of methods, i.e., a direct insertion method and a side insertion method. The spinous processes of the cervical vertebra, the upper segment of the thoracic vertebra and the lumbar vertebra are parallel to each other, and a direct approach is used for multiple main openings; the spinous processes of the middle and lower segments of the thoracic vertebrae are imbricated, and the lateral approach can be used when the puncture is difficult. For those with calcification of the supraspinal ligament and limitation of spinal curvature in the elderly, the approach is usually adopted. However, in any puncture method, since most of clinical puncture methods are blind puncture at present, and operation needs to be performed by the experience of medical staff, the puncture depth cannot be accurately controlled, and the puncture position is often deviated due to body movement and other reasons after the pain of a patient occurs in the puncture process, so the following complications are easily caused: local anesthetic general toxic reaction, epidural hematoma, mistaken entry into subarachnoid space, mistaken entry into subdural space, catheter rupture, abnormal wide block, dural puncture and headache, nerve injury, and the like.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an epidural puncture auxiliary device to the use of solving current pjncture needle can only be worn through the blind, need rely on the experience, the problem of the unable accurate control depth of penetration and position.
The epidural puncture auxiliary device in the scheme comprises a fixing component and a visual ultrasonic component; the fixing assembly comprises two fixing plates and a Jiong-shaped bridging plate, two end parts of the bridging plate are respectively connected with one fixing plate, the lower surface of the fixing plate is fixedly connected with a rubber sheet with adhesive force, and the surface of the rubber sheet is provided with release paper; the middle part of the bridging plate is provided with a fixing clamp for fixing the puncture needle;
the visual ultrasonic assembly comprises a PLC single chip microcomputer, a display and an ultrasonic probe, and the PLC single chip microcomputer and the display are arranged in the middle section of the bridging board; the display is connected with the PLC singlechip through an electric signal, and the ultrasonic sleeve head is connected with the PLC singlechip through a power line; the display comprises a puncture needle visual display screen and a baroreceptor display screen; a light source information feedback channel and a pressure receptor feedback channel are arranged in the ultrasonic probe.
The working principle of the scheme is as follows: when carrying out epidural needle puncture, can detect the puncture depth of pjncture needle on patient's health through ultrasonic probe, with information through light source information feedback channel and pressed sensor feedback channel feedback to the PLC singlechip, the PLC singlechip presents the puncture depth information of pjncture needle to the visual display screen of pjncture needle after with the identification information again, the pressure condition when will puncture presents on the pressure sensor display screen, the doctor observes the information of the presentation on the visual display screen of pjncture needle and the pressure sensor display screen, observe the particular case of each layer puncture, judge according to the phenomenon of observing whether the pjncture needle is in skew epidural puncture clearance, whether have touching angioneurotic etc, thereby reduce the complication of epidural puncture.
The beneficial technical effect of this scheme is: when the device is used for puncturing, the puncture depth and the position of the puncture needle detected by the ultrasonic probe are used for presenting detected information on the visual display screen and the baroreceptor display screen of the puncture needle, so that a doctor can judge the specific situation of the puncture, and the puncture point and the puncture depth can be timely and accurately adjusted.
At present, in the operation process of the epidural anesthesia clinically, an anesthesia doctor usually operates by holding the epidural puncture needle by hand, the epidural puncture needle is not fixed stably, and the puncture needle swings due to external force when injecting medicine inevitably, so that the harm of secondary puncture or incomplete blockage and the like is caused to a patient. When this scheme of use punctures, tears the release paper on the surface of rubber skin, but the rubber skin adhesion skin that has the adhesion utilizes the needle tubing fixation clamp to fix the needle tubing, avoids the needle tubing to rock, and then makes the pjncture needle of being connected with the needle tubing rock to the easy wobbling problem of pjncture needle atress when overcoming the injection medicine. And combine visual supersound subassembly and fixed subassembly, make visual supersound subassembly near the doctor like this, conveniently observe, simultaneously, this scheme compact structure conveniently goes out to salvage and carries.
Clinical T represents the positioning and truncation of thoracic vertebral bodies, including T1-T9. Relevant research shows that epidural space pressures of T1-T9 are positive values. Especially, the epidural space pressure of T3 and T6 points of normal pregnant women is (14.1 +/-2.1) mmHg, (21.3 +/-4.0) mmHg; t3 and T6 points of non-pregnant women have epidural space pressure of (11.1 +/-4.6) mmHg and (17.0 +/-5.3) mmHg, so the scheme can more clearly judge whether the epidural space is in the epidural space by using a baroreceptor feedback channel to feed back a numerical value, and the incidence rate of epidural anesthesia complications is further reduced.
Furthermore, be equipped with the cylinder handle on the syringe fixing clip, be equipped with the round hole and the screw hole of mutual intercommunication on the bridging board, the axis of round hole is perpendicular with the axis of screw hole, and the cylinder handle penetrates in the round hole, and screw hole female connection has the screw, and the screw is fixed the cylinder handle in the round hole. Through the scheme, the needle tube fixing clamp can be rotationally adjusted before the cylindrical handle is locked by the screw, so that the angle between the puncture needle and the skin can be adjusted according to actual needs.
Furthermore, a ball bearing is arranged on the bridging plate, a rotating shaft is fixedly connected in the ball bearing, and the display is connected to the rotating shaft. The bridge connection plate and the display are connected through the ball bearing and the rotating shaft, the orientation of the display can be rotated, the position of the display is adjusted at any time, and a doctor who is not fixed in position can observe information on the display conveniently.
