Abstract
The invention relates to a bone pressure-reducing needle comprising a needle point, self-tapping threads, a needle rod and a handle. The middle of the handle and the back end of the needle rod are connected in a T shape, the front part of the needle rod is provided with the self-tapping threads, and the needle point arranged at the front ends of the self-tapping threads is a triangular needle point. Because the needle point is in a triangular cone shape, the bone pressure-reducing needle is easily penetrated into a bone, the self-tapping threads behind the needle point can enhance the propulsive force of the needle point so that the bone pressure-reducing needle smoothly drills on the bone during rotation, and the bone pressure-reducing needle is penetrated by clockwise rotation and is withdrawn by counterclockwise rotation. The bone pressure-reducing needle can drill a smooth and rounded pressure-reducing pore on the bone with raised internal pressure under the pressure and the slow rotation state of the handle in a straight line shape so that overhigh pressure in a bone cavity can be discharged out of the pore, the bone has balanced external and internal pressure, and the pressure in the bone returns to normal. The invention has the advantages of simple and reasonable structure, safe and convenient use, good pressure-reducing effect, small wound, rapid recovery after operation and the like, fills the blank of special bone pressure-reducing appliances for needle and knife operations and is suitable for all-level hospitals and clinics.
Description
Technical field
The present invention relates to a kind of pin, particularly a kind ofly increase the needle set for the treatment of osteoarthritis by alleviating intra-osteal pressure, is a kind of special needle in the operation of pin cutter, belongs to medical instruments field.
Background technology
Skeleton can cause that intra-osteal pressure increases by many reasons, and clinical manifestation is the long-term pain in joint, and the antiinflammatory of taking medicine etc. is difficult to take effect, and surgery boring treatment commonly used alleviates bones pressure, can make intra-osteal pressure recover normal and pain relieving.But at present because of no specific purpose tool, can only adopt electric drill boring or thicker Kirschner wire to undergo surgery, but the damage that electric drill boring causes the patient is bigger, and Kirschner wire is difficult to drilling bore hole, also exist simultaneously problems such as environmental requirement height and infection rate after abortion operation height, the medical worker is had relatively high expectations, general hospital should not be carried out.
Summary of the invention
The objective of the invention is in order to fill up the deficiency of medical apparatus and instruments, for the bone decompression operation designs the simple and reasonable of a kind of special use, wound is little, and effect of easing stress is good, bone pressure-reducing needle safe and convenient to use.
Bone pressure-reducing needle of the present invention is characterized in that being made up of needle point, self-tapping type screw thread and shank and handle, and described handle middle part is "T"-shaped with the shank rear end and is connected, and the shank front portion is provided with the self-tapping type screw thread, and self-tapping type screw thread front end is provided with the prismatic needle point.
For the ease of inserting needle, described shank external diameter is elected 1.1～1.25mm as, and shank length is elected 50～120mm as; The length of described self-tapping type screw thread is elected 5mm as; The length of described prismatic needle point is elected 1～3mm as.
For the ease of operation, described handle is an in-line, and the handle external diameter is 5～10mm, and decreased food is 50～100mm.
For the ease of grasping depth of needle, can on shank, be provided with sounding mark, in order to keep sufficient intensity, should select for use stainless steel material or silver-plated steel to make,
Bone pressure-reducing needle of the present invention, because needle point is the rhizoma sparganic taper, be convenient to firmly thrust sclerotin, the screw thread of needle point back is selected the self-tapping type screw thread for use, the external diameter of this self-tapping type screw thread be from after tapered forward, can hole on skeleton smoothly in rotation, inserting needle is diverted in dextrorotation, is rotated counterclockwise to be used for the withdraw of the needle.During use, can get out the smooth mellow and full less decompression aperture of diameter on the skeleton with intrinsic pressure rising place under the state of the pressure of in-line handle and slowly rotation, the both available rotating cycle control of drilling depth also can be according to sounding mark and feel control, again because shank and screw rod are all very thin, non-corrosive has simple and reasonable, safe and convenient to use, advantages such as effect of easing stress is good, and the little and post-operative recovery of wound is fast.Can be promptly manually actuated under general curative sterilization situation, filled up the blank of bone decompression special implement for pin cutter operation, be fit to hospitals at different levels and clinic and use.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of bone pressure-reducing needle of the present invention.
The specific embodiment
Referring to accompanying drawing, 1 among the figure is needle point, the 2nd, and self-tapping type screw thread, the 3rd, shank, the 4th, handle.Described handle 4 middle parts are T-shaped with the rear end of shank 3 and are connected, and shank 3 front portions are provided with self-tapping type screw thread 2, and the needle point 1 that self-tapping type screw thread 2 front ends are provided with is the prismatic needle point.
For the ease of inserting needle, described shank 3 external diameters are elected 1.1～1.25mm as, and shank length is elected 50～120mm as; The length of described self-tapping type screw thread 2 is elected 5mm as; The length of described prismatic needle point is elected 1～3mm as.
For the ease of operation, described handle 4 is an in-line, and the handle external diameter is 5～10mm, and decreased food is 50～100mm.
Can be provided with sounding mark on the described shank 3, described needle point 1, screw thread 2 and shank 3 select for use stainless steel material or silver-plated steel to make.
Bone pressure-reducing needle of the present invention, during use, as when suffering from the calcaneus hyperbarism patient hand-manipulating of needle, can select a wherein side in heel calcaneus portion both sides, the conventional skin degerming of elder generation, after the local anaesthesia, hold handle, bone pressure-reducing needle is thrust skin to sclerotin, with pressure needle point is thrust sclerotin slightly, continue firmly to turn clockwise a few after thrusting sclerotin, forward to and represent when feel lightens that needle point has penetrated into bone cavity, illustrate skeleton have been drilled through an aperture, can stop pin this moment, can withdraw of the needle sterilization behind the another mistake hour hands rotary handle.Because of this aperture arranged, the too high pressure in the bone cavity can be discharged from this aperture, make the bone internal and external pressure balance and make intraosseous pressure recover normal, make because of intra-osteal pressure and increase the effect that the pain skeleton that causes reaches anti-inflammatory analgetic.Have simple and reasonablely, safe and convenient to use, the bone effect of easing stress is good, easy and simple to handle should going, advantage such as the little and post-operative recovery of wound is fast.Can be promptly manually actuated under general curative sterilization situation.Filled up the blank of bone decompression special implement for pin cutter operation, be fit to hospitals at different levels and clinic and use.
