Specific embodiment
The embodiments of the present invention that the following is further explained with reference to the attached drawings.
Refer to shown in attached drawing 1 and attached drawing 2, a kind of medical puncture needle, including puncture needle ontology 1, press head 2, sliding sleeve 3,
Spring 4 and snap ring 5；The puncture needle ontology 1 includes syringe needle 101 and shank 102, and the syringe needle 101 is arranged described
102 front end of shank；The shank 102 and 101 junction of syringe needle extend outward to form rectangle fixture block 103；It is described
Press head 2 include front end insertion section 201 and tail end press section 202；The shank 102 is arranged in the insertion section 201
Rear end, and can be moved axially along the puncture needle ontology 1；The sliding sleeve 3 is sleeved on the insertion section 201, and can
It is moved axially along the insertion section 201；The spring 4 is sleeved on the insertion section 201, one end and the puncture
Needle ontology 1 contacts, and the other end is contacted with the sliding sleeve 3；5 one end of snap ring described in a pair is arranged on the sliding sleeve 3, separately
One end is connect with rectangle fixture block 103 described in a pair.
The snap ring 5 and the sliding sleeve 3 are hinged, and the snap ring 5 can be rotated around the sliding sleeve 3, with it is described
Rectangle fixture block 5 be detached from and connection.
The snap ring 5 is rectangular ring structure；Described 5 liang of inner walls of snap ring are arranged several raised 501 along its length,
And be axially evenly arranged along the snap ring 5, raised 501 connection of the rectangle fixture block and different location can be changed
The sliding sleeve 3 and the distance between the rectangle fixture block 103, to change the stroke of the spring 4.
The distance between two neighboring described protrusion 501 is greater than the thickness of the rectangle fixture block 103, give described in
The enough shaft orientation moving ranges of press head 2, to simulate the puncture sense of different type skin.
The insertion section 201 is cylindrical structure, and the press section 202 is chondritic, the pressing of larger area
Portion 202 can meet different practitioners and carry out pressing practice.
It further include cord-embedding needle 6；201 front end of insertion section is arranged in the cord-embedding needle 6, and is located at the syringe needle
101 inner cavities, the cord-embedding needle 6 can play the role of auxiliary guiding, prevent the press head 2 during practice from described
Puncture needle ontology 1 in fall off.
6 diameter of cord-embedding needle is less than 101 internal diameter of syringe needle, so that the cord-embedding needle 6 can be in the needle
It is free to slide in first 101.
6 length of cord-embedding needle is less than 101 length of syringe needle, and the cord-embedding needle 6 primarily serves guiding role,
If the cord-embedding needle 6 is too long, it can be stretched out from the syringe needle 101, the cord-embedding needle 6 can take the lead in during practice
Skin is punctured, so that the syringe needle 101 loses practice effect.
201 length of insertion section is greater than 102 length of shank, to expand the insertion section 201 in institute
The scope of activities in shank 102 stated.
101 length of syringe needle is greater than 102 length of shank, and in puncture needle, the shank 102 plays connection
Effect, therefore length is less than 101 length of syringe needle.
201 peripheral wall of insertion section is provided with graduation mark 203, by observing the graduation mark 203, it may be determined that described
Press head 2 be pressed into depth, so that it is determined that pressing the dynamics and time that certain distance needs under the dynamics.
In use, puncture needle practitioner adjusts the sliding sleeve 3 and the rectangle fixture block by the snap ring 5
Spacing between 103, so as to adjust the indentation length of the spring 4, to simulate different types of skin type, when described
The indentation of spring 4 length is smaller, and the spring 4 is in diastole state, and the pressing dynamics of the press head 2 are relatively small, then
The skin for being easier to puncture is represented, practitioner can be obtained by the pressing press head 2 and wear to such skin elasticity
Thorn dynamics and feel, when the spring 4 is pressed into, length is larger, and the spring 4 is in compressive state, the press head 2
Pressing dynamics it is relatively large, then it represents that compare the skin for being difficult to puncture, practitioner can obtain by the pressing press head 2
It obtains to such puncture dynamics and feel for making a farfetched comparison elasticity.
In conclusion the beneficial effects of the utility model are, firstly, the medical puncture needle passes through the flexible of adjustment spring
Amount, changes the rigidity of spring, so that the skin of different type elasticity is simulated, so that puncturing practitioner practices different types of skin
Skin targetedly punctures dynamics and feel to obtain, secondly, the medical puncture needle has structure simple, easy to operate, is suitble to
New Shanxi practitioner uses.
The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model,
Any equivalent structural transformation made using the contents of the description of this utility model is directly or indirectly related with other are attached to
The technical field of product, is also included in the patent protection scope of the utility model.
