Abstract
The utility model relates to a novel cerebrospinal fluid sampler and belongs to the field of medical equipment. The novel cerebrospinal fluid sampler consists of a needle tip 1, a needle rod 2, a needle handle 3 and a needle core 4 and is characterized in that a miniature camera 5 is arranged on the needle tip; the miniature camera 5 is connected with a data line 6; the data line 6 runs in the wall of the needle rod 2; a USB ( Universal Serial Bus ) plug 7 is arranged at the tail end of the data line and is used for being connected with a computer for imaging; a position fixer 8 is arranged on the needle rod 2; a bypass pipe 9 is arranged on the side of the needle handle 3; and a pressure gauge 10 is connected to the tail end of the bypass pipe 9. The novel cerebrospinal fluid sampler is simple in structure and convenient to use, integrates puncture, pressure measurement, sampling, imaging and positioning, can effectively control the position and the depth of puncture, avoids spinal cord injury, can continuously observe intracranial pressure and is an ideal cerebrospinal fluid sampler.
Description
Technical field: this utility model belongs to medical instruments field, particularly a kind of collection puncture, pressure measurement, sampling, forms images, is positioned one, can effectively control the position and the degree of depth of puncture; Avoid spinal cord injury; Continue the observation intracranial pressure, novel cerebrospinal fluid sampler simple in structure, easy to use.
Background technology: in the clinical treatment activity, cerebrospinal fluid sampling art is a basic skill operation commonly used, is used for that disease patients such as encephalitis or cerebral hemorrhage are carried out cerebrospinal fluid and gets inspection, intracranial pressure measurement and injection through vertebral canal medicine etc.At present, the cerebrospinal fluid sampler of clinical use is a kind of puncture needle of single opening, when implementing the cerebrospinal fluid puncturing sampling; The main position and the degree of depth of feeling to confirm the puncture needle place that relies on range estimation and patient; After puncturing successfully, extract the puncture nook closing member out, connect pressure-measuring pipe, probe tube and syringe then successively; Measure intracranial pressure, take operations such as sample and injection medicine.In this process, the opening part of puncture needle handle need repeatedly be changed utensil, causes the puncture needle displacement easily; Nervous tissues such as Spinal Cord increase the danger of patient's intracranial infection, and can not guarantee to continue observation intracranial pressure situation of change; Especially for cerebral hemorrhage, intracranial hypertension patient; The fast lifting of intracranial pressure brings out various cerebral hernias easily and forms, and jeopardizes patient's life.
Summary of the invention: the purpose of this utility model is to provide a kind of collection puncture, pressure measurement, sampling, forms images, is positioned one; Can effectively control the position and the degree of depth of puncture, avoid spinal cord injury, continue the observation intracranial pressure; Novel cerebrospinal fluid sampler simple in structure, easy to use.
For realizing above-mentioned purpose, this utility model has been taked following technical scheme: this novel cerebrospinal fluid sampler, constitute by needle point, shank, needle handle and nook closing member, and needle point is provided with minisize pick-up head; Minisize pick-up head connects data wire, and the data wire traveling is in the wall of shank, and the end of data wire is provided with USB plug, is used for connecting the computer imaging; Shank is provided with the fixed-site device, can be used to the position and the degree of depth of fixing puncture, avoids its displacement; Cause the damage of nervous tissues such as spinal cord, the side of needle handle is provided with a side siphunculus, and the end of side siphunculus connects pressure gauge; After puncturing successfully, can be used to continue to observe intracranial pressure and change, so that in time make handled.
This utility model, simple in structure, easy to use, collect puncture, pressure measurement, sampling, form images, be positioned one, can effectively control the position and the degree of depth of puncture, avoid spinal cord injury, continue the observation intracranial pressure, be a kind of ideal cerebrospinal fluid sampler.
Description of drawings: this utility model is described further below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of this utility model.
With reference to accompanying drawing 1,1, needle point, 2, shank, 3, needle handle, 4, nook closing member, 5, minisize pick-up head, 6, data wire, 7, USB plug, 8, the fixed-site device, 9, the side siphunculus, 10, pressure gauge.
The specific embodiment: this utility model, be made with stainless steel material, constitute by needle point 1, shank 2, needle handle 3 and nook closing member 4; Needle point 1 is provided with minisize pick-up head 5, and minisize pick-up head 5 connects data wire 6, and data wire 6 travelings are in the wall of shank 2; The end of data wire 6 is provided with USB plug 7; Shank 2 is provided with fixed-site device 8, and the side of needle handle 3 is provided with a side siphunculus 9, and the end of side siphunculus 9 connects pressure gauge 10.
When using this utility model, earlier USB plug 7 is connected on the computer, opens video, then; Under the video direct-view, puncture by routine operation, in piercing process, in conjunction with video; The position and the degree of depth of regulation and control punctures, puncture successfully after, with holder 8 fixed-site is lived; In order to avoid in the operation of back, cause insecondary damage because needle point is shifted, extract puncture nook closing member 4 then out, can observe intracranial pressure and get the inspection cerebrospinal fluid.
