Abstract
The utility model relates to a puncture medical apparatus related to a thoracic cavity, in particular to a puncture needle for a lumbar vertebra. The puncture needle comprises a cannula, a needle core and a needle seat. A needle head is tapered. The tail portion of the needle core is fixedly connected with the needle seat in threaded connection with the tail portion of the cannula. Liquid absorbing chambers are arranged in the side wall of the cannula and communicated with the outside by stretching out the head portion of the cannula. The tail portion of the cannula is provided with an observation chamber with a transparent sidewall. The chamber is communicated with the liquid absorbing chambers. An open-closed liquid outlet is formed in the observation chamber. The tail portion, behind the observation chamber, of the cannula is provided with a latex drainage catheter which has one end communicated with a lumen where the needle core is disposed and the other end equipped with a glass bead tightly adhered to the inner wall of the drainage catheter.

Description
Technical field
This utility model relates to the relevant puncture in a kind of thoracic cavity medical apparatus and instruments, is a kind of lumbar puncture needle specifically.
Background technology
Lumbar puncture is one of clinical conventional operation of Neurology Department, is mainly used in cerebrospinal pressure and measures, and extracts cerebrospinal fluid, to subarachnoid space injection of medicine, and cerebrospinal fluid radiography etc.In order to implement safely and effectively this operation, doctor need understand contraindication, the relevant anatomy of lumbar puncture and at utmost reduce the method that complication is caused danger.Although lumbar puncture is seldom caused danger, once occur, can be very serious, even likely jeopardize patient's life.Understand indication, contraindication and the correct operational approach of lumbar puncture, can dangerous incidence rate is down to minimum.Lumbar puncture utensil used is lumbar puncture needle, and conventional lumbar puncture needle comprises syringe needle, needle stand and the nook closing member of hollow at present, and syringe needle tail connects needle stand.Before puncture, first nook closing member is inserted in the syringe needle cavity of syringe needle, when syringe needle enters after human body together with nook closing member, in order to judge whether syringe needle enters canalis spinalis, nook closing member need be extracted in syringe needle cavity, be observed cerebrospinal fluid and whether in syringe needle cavity, flow out, flow out if any cerebrospinal fluid, lumbar puncture success is described, then connects pressure-measuring pipe (the pressure-measuring pipe is here the transparent pressure-measuring pipe of upper and lower side open hollow) and carry out cerebrospinal pressure mensuration.Extract cerebrospinal fluid or injection of medicine by needle stand.Although above-mentioned lumbar puncture needle is simple in structure, but also exist following not enough: 1, in order to judge whether syringe needle inserts canalis spinalis, nook closing member need be extracted in syringe needle cavity, whether observe cerebrospinal fluid flows out in syringe needle cavity, if cerebrospinal fluid does not flow out, again nook closing member is inserted in the syringe needle cavity of syringe needle, then puncture procedure again, extend the operating time, increase operating difficulty.2, easily there is cerebrospinal fluid seepage and headache after causing puncturing in lumbar puncture.3, sample collection only needs on a small quantity, and permeates too fast meeting and cause Headache, and serious meeting causes cerebral hernia.
Utility model content
This utility model does not need to extract nook closing member can judge whether syringe needle inserts canalis spinalis, reduces the operating time, and utilizes bead and latex tubing control cerebrospinal fluid to flow out speed and discharge, avoids Headache, reduces operation risk; The syringe needle of taper is also conducive to reduce Principle of Pain.
This utility model for achieving the above object, provides a kind of lumbar puncture needle, comprises sleeve pipe, nook closing member and needle stand, and the syringe needle of described nook closing member is taper; Nook closing member is positioned at casing pipe intracavity, and nook closing member afterbody is fixedly connected with needle stand, and needle stand is connected with sleeve pipe tailing screw flight; Described sleeve pipe interior is provided with 4-8 imbibition chamber along the puncture needle direction of motion, is stretched out and is in communication with the outside by sleeve pipe head; Described sleeve pipe afterbody is provided with observation chamber, and described observation chamber is provided with transparent sidewall, and chamber is communicated with imbibition chamber; On described observation chamber, be provided with liquid outlet to be opened/closed, be convenient to balance external and internal pressure and after use, derive imbibition intracavity liquid, in order to using next time; Described sleeve pipe afterbody, the rear of observation chamber is provided with catheter, and described catheter is latex tubing, and its one end is communicated with nook closing member place tube chamber, and the other end is provided with bead, and described bead is close to catheter inwall; Described lumbar puncture needle comprises the plug being connected with sleeve pipe tailing screw flight, after nook closing member is taken out, screws plug, gets liquid.
Further, described sleeve pipe sidewall is provided with scale, the localised puncture degree of depth, and mark thrusts the degree of depth in human body.
Further, described sleeve pipe head is blunt nosed, avoids tip to move, and punctures histoorgan.
Before puncture, doctor brings after sterile glove, and with suitable disinfectant sterilization skin, from center, one encloses outwards expansion.Then cover disinfecting towel.
Doctor can, patient is carried out before skin degerming, use anesthetics emulsifiable paste for it is local.At skin degerming and spread after disinfecting towel, can subcutaneous injection local anesthetic, also can use whole body tranquilizer and analgesic.
Doctor finds out after boundary mark again, demarcates puncture position at the upper limb of midline position, next spinous process, inserts the puncture needle with nook closing member, and syringe needle is headward, is approximately 15 degree, seemingly towards the direction of patient's umbilical part.If inserting needle correct position, puncture needle should pass through skin, subcutaneous tissue, supraspinal ligament, interspinal interspinal ligaments, ligamenta flava, epidural space (comprising interior vertebral venous plexus, spinal dura mater and arachnoidea) successively, enter subarachnoid space, and between cauda equina nerve root.In the time that puncture needle passes through ligamenta flava, doctor can feel that one breaks through sense.Now, open liquid outlet, in observation chamber, whether have cerebrospinal fluid.Unsuccessful if punctured, and encounter bone, puncture needle is retreated to subcutaneous tissue, but do not exit skin, adjust after direction inserting needle again.
After finishing using, discarded puncture needle is focused on or open liquid outlet, derive the liquid of imbibition intracavity, puncture needle sterilization is for subsequent use.
The beneficial effects of the utility model are: 1, utilize siphon principle that imbibition chamber is set, can judge without nook closing member is extracted whether syringe needle inserts canalis spinalis, reduce operating difficulty, reduce the operating time; 2, utilize bead and latex tubing can control cerebrospinal fluid and flow out speed and discharge, avoid Headache, reduce operation risk.3, the syringe needle of taper can make the fiber of dural sac scatter, and can not be cut off, and is conducive to avoid cerebrospinal fluid seepage, reduces Principle of Pain sense.
