Abstract
The utility model discloses a self-tapping puncture needle used in vertebral body shaping surgery, characterized in composed of a needle tube which one end is arranged with a needle tube handle, wherein the needle tube is provided with a channel inside, the channel is provided with a needle core inside while one end of the needle core is provided with a needle core handle, the needle tube is provided with a self-tapping screw for controlling the motion of the needle tube. The utility model can resolve the defects of puncture needle of vertebral body shaping surgery which can not accurately position and puncture in uniform speed, with accurate positioning and uniform-speed puncture. The utility model can eliminate the inaccuracy of general puncture, to control the injection point at ideal area to reduce puncture hurt, avoid skeleton cement leakage, improve the disperse range of skeleton cement in ill vertebral body, and avoid repeated positioning, thereby reducing the surgery time, reducing radiation hurt, improving puncture accuracy, improving success rate, and reducing surgery time significantly.
Description
[technical field]
This utility model relates to a kind of medical apparatus and instruments, a kind of self tapping puncture needle that is used for vertebroplasty of saying so more specifically.
[background technology]
Along with the appearance of social senilization, senile compression fracture of vertabral body is more and more clinically, and the past handles mostly to be at this type of patient and lies up and symptomatic treatment.Along with vertebroplasty carrying out clinically, it has become the major measure that compression fracture of vertabral body senile, the impassivity pressure symptom is treated, make many gerontal patients in time remove pain, shorten simultaneously the bed rest time of this type of fracture patient greatly, reduced the various complication that long-term bed brought.Yet the existing puncture needle that is used for vertebroplasty the penetration damage patient occurs easily when operation, bone cement related complication such as leak outside perhaps occurs, and is perplexing extensively carrying out of vertebroplasty always.These complication be since the operation in can not accurately locate and at the uniform velocity the puncture cause.In carrying out the vertebral body piercing process, conventional puncture needle smooth surface, advance, be difficult to accurately control its depth during the withdraw of the needle, resistance is bigger when passing through fine and close sclerotin, be difficult to inserting needle, need advance with big strength, enter the interior back of pedicle of vertebral arch and vertebral body because the puncture needle smooth surface, pedicle of vertebral arch and vertebral body osteoporosis, resistance descends suddenly, inertia along with strength in patient's hands, depth of needle is difficult to hold, and easily causes the puncture direction to change and breakthrough vertebral body the place ahead cortex, and perhaps paracentesis depth is shallow excessively, need further to adjust depth of needle, advance strength to be difficult to control, make the puncture accuracy be difficult to reach, the bone cement injection point is undesirable.It is shallow to puncture, and easily causes bone cement to the infiltration of vertebral body trailing edge and in vertebral body internal diffusion inequality; It is dark to puncture, and easily breaks through anterior margin of vertebral body, causes vertebral body the place ahead blood vessel and other visceral organ injury, can cause bone cement to the vertebral body periphery leakage simultaneously.In order to reach ideal point of puncture, often need position repeatedly, operating time is prolonged at double, accurate puncture is the key that guarantees the vertebroplasty success.It is very high to use existing puncture needle that the operant level of operative doctor and the mental status are required, and cannot say for sure very much to demonstrate,prove operation safety.Being badly in need of a kind of puncture needle that can accurately control paracentesis depth and at the uniform velocity puncture is applied in the vertebroplasty.
[utility model content]
This utility model purpose is to have overcome the deficiency that puncture needle can not accurately be located, can not at the uniform velocity be punctured in the existing vertebroplasty, and a kind of self tapping puncture needle that can accurately locate and at the uniform velocity puncture is provided.
This utility model is achieved through the following technical solutions:
A kind of self tapping puncture needle that is used for vertebroplasty, it is characterized in that: it comprises needle tubing, is provided with syringe handle at an end of needle tubing, be provided with passage in the needle tubing, be provided with nook closing member in passage, nook closing member one end is provided with the nook closing member handle, and described needle tubing is provided with the tapping screw thread of may command needle tubing advance and retreat.
Aforesaid a kind of self tapping puncture needle that is used for vertebroplasty is characterized in that described needle tubing is provided with scale marker.
Aforesaid a kind of self tapping puncture needle that is used for vertebroplasty is characterized in that the front end of described needle tubing is provided with sleeve as service aisle.
Aforesaid a kind of self tapping puncture needle that is used for vertebroplasty is characterized in that being provided with female thread in the described sleeve.
Aforesaid a kind of self tapping puncture needle that is used for vertebroplasty, it is characterized in that described syringe handle is provided with screens, described nook closing member handle is provided with the card base that can block screens after the rotation, also is provided with the postive stop baffle that when it is attached to syringe handle card base blocks screens on the nook closing member handle.
Compared with prior art, this utility model has following advantage:
This utility model is provided with tapping screw thread and scale marker on needle tubing, can be implemented in the accurately location and the at the uniform velocity inserting needle and the withdraw of the needle in the vertebroplasty, no certainty when having eliminated conventional puncture and advancing, make injection point be controlled at ideal zone, reduced penetration damage, prevented that bone cement from exosmosing, increased the range of scatter of bone cement in sick vertebra, and avoid locating repeatedly, thereby shortened the time of whole surgery, reduced patient's radiation injury.Can make the vertebroplasty puncture procedure more accurate, success rate improves greatly, and operating time obviously shortens.

[specific embodiment]
A kind of self tapping puncture needle that is used for vertebroplasty, comprise needle tubing 1, end at needle tubing 1 is provided with syringe handle 2, be provided with path 10 1 in the needle tubing 1, in path 10 1, be provided with nook closing member 3, nook closing member 3 one ends are provided with nook closing member handle 4, and described needle tubing 1 is provided with the tapping screw thread 102 of may command needle tubing 1 advance and retreat.Needle tubing 1 is provided with scale marker 103, can be easy to judge penetration depth.The front end sleeve of needle tubing 1 is provided with sleeve 5, can avoid screw thread 102 injured skins and soft tissue, is provided with female thread 501 in the sleeve 5, rotatable inserting needle.Nook closing member handle 4 is provided with postive stop baffle 402, and when postive stop baffle 402 was attached to syringe handle 2, card base 401 promptly blocked screens 301.
During use, earlier needle tubing 1 is inserted sleeve 5, again nook closing member 3 is inserted in the path 10 1 of needle tubing 1, rotation nook closing member handle 4 makes card base 401 block screens 301, tip alignment site of puncture with nook closing member 3 firmly enters, when entering into sleeve 5 and touch bone, sleeve 5 forms a service aisle, the syringe handle 2 that turns clockwise at the uniform velocity rotates into, in the time of can observing screw thread 102 and scale marker 103 and enter into designated depth, rotation nook closing member handle 4 makes card base 401 break away from screens 301, extracts nook closing member 3 out, in path 10 1, inject bone cement, insert nook closing member 3 once more after injection is finished, be rotated counterclockwise syringe handle 2, needle tubing 1 at the uniform velocity withdraws from, when screw thread 102 all withdraws from the vertebral body bone, extract sleeve 5 out, puncture needle is promptly finished the bone cement injection.
