Needle for giving medical treatment vertebra with drugs injecting function}

The present invention relates to a needle for spinal surgery, and more particularly, to a needle for spinal surgery capable of injecting drugs to inject anesthetics directly into the vertebrae to relieve pain as much as possible.

In general, bone marrow transplantation is transplantation of bone marrow cells to stimulate blood cell formation in patients with leukemia, aplastic anemia, immunodeficiency, etc. In order to perform bone marrow transplantation, a procedure such as bone marrow examination or bone marrow extraction is essential. Entails.

Such a bone marrow test or bone marrow extraction is usually by using a special needle such as a Thomas needle (Thomas needle) by drilling a part of the iliac bone (ilium), it is possible to examine or collect the bone marrow.

Vertebroplasty is performed on patients with chronic back pain or compression fractures caused by vertebral osteoporosis. Plastic surgery will be performed.

Such vertebral vertebral surgery is somewhat different from the bone marrow examination or bone marrow extraction procedure in that it injects a therapeutic material into the vertebra, but due to the nature of the procedure that involves puncturing skin and bone for the procedure, It is used in the form of a special needle for bone marrow examination or bone marrow extraction.

1 and 2 are shown for the conventional spinal surgery needle as described above, it is composed of a main handle and an auxiliary handle.

In other words, a tube-shaped injection tube 11 is mounted below the main handle 10, and a needle insertion unit 12 is protruded in an upper center thereof, and a thread is formed on an outer circumferential surface of the needle insertion unit 12. The puncture needle 21 is mounted at the lower center of the auxiliary handle 20. When the main handle 10 and the auxiliary handle 20 are coupled as shown in FIG. 2, the puncture needle 21 is inserted into the center of the needle insertion unit 12 and penetrated into the injection tube 11. An end of the puncture needle 21 is configured to protrude out of the injection tube 11.

As described above, a method of collecting bone marrow using a conventional spinal surgery needle is anesthetized on the skin of a patient to be punctured, and the main handle 10 and the auxiliary handle 20 are coupled to each other. In the end of the puncture needle 21 penetrates into the skin. Afterwards, when the end of the perforation needle 21 comes in contact with the vertebral spine, the auxiliary handle 20 is blown up using a hammer or the like to make a hole in the vertebral spine, and when the end of the injection tube 11 reaches the bone marrow, The auxiliary needle 20 is separated from the main handle 10 to draw out the puncture needle 21. Then, by inhaling the syringe coupled to the needle insertion portion 12 of the upper portion of the main handle 10, it is possible to collect the bone marrow in the sacrum spine.

Similar to the bone marrow harvesting method, vertebral osteoplasty also injects bone cement into the bone through the injection tube after penetrating the skin and the bone, thereby making it possible to harden the weakened bone.

However, the above-described conventional needle for spinal surgery has the effect of reducing the pain of the patient through anesthesia when penetrating the skin, but when the bone penetrates the bone is not anesthetized, the patient complains of extreme pain, Due to this, the patient not only feels fear and strong rejection of the procedure, but is also in a situation in which the pain of the procedure leads to fainting.

The present invention has been made in order to solve the conventional problems as described above, for spinal surgery in which the drug can be injected into the bone directly to the bone prior to the procedure to puncture the bone to reduce the pain of the patient as much as possible To provide the needle.

The configuration of the present invention for achieving the above object is, when the injection tube of the tubular form in the main handle, the auxiliary needle is mounted on the auxiliary handle, when the auxiliary handle is coupled to the main handle inside the injection tube In the needle for spinal surgery, in which the puncture needle is inserted and mounted so that the end of the puncture needle protrudes out of the injection tube, a drug injection unit is formed on one surface of the main handle so as to communicate with an internal passage through which the puncture needle is inserted, and the drug injection unit Equipped with an opening and closing cap, the injection groove is formed on one side of the puncture needle so that the drug injected into the drug injection unit can be administered along the puncture needle, and sealing to prevent drug leakage between the main handle and the auxiliary handle. Install the means.

The present invention through the above problem solving means, anesthesia is injected along the injection groove formed in the puncture needle to anesthetize the vertebrae to be punctured, there is an effect that can significantly reduce the pain of the patient, thereby It also has the effect of providing a comfortable treatment environment for both the operator and the patient by reducing fear and rejection.

Thus, since the space 140 is formed in a form surrounding the perforation needle 210, the injected drug is preferentially supplied to the space 140, and thus the drug injection unit 130 and the injection groove 230 are formed. Regardless of the position of the drug can be naturally injected along the injection groove (230).

The auxiliary handle 200 is coupled to the upper surface of the main handle 100, the lower surface is curved so as to be in surface contact with the upper surface of the main handle 100, and the needle mounting portion 220, 220 'in the center of the lower surface Protruding to form a hook 250 is formed on both sides of the needle mounting portion 220, 220 'protruding one end, the stepped formed on both sides of the upper surface of the main handle (100) when combined with the main handle (100) To be locked at 150).

In addition, the needle mounting parts 220 and 220 'are fixed to the center of the puncture needle 210 downwardly, when combined with the main handle 100, the puncture needle 210 is a needle insertion unit 120, 120 It is inserted into the injection tube 110 through ') to configure the end of the puncture needle 210 to protrude to the end of the injection tube (110). At this time, by forming the injection groove 230 along the longitudinal direction of the drilling needle 210 on one side of the drilling needle 210, the drug injected through the drug injection unit 130 is guided to the injection groove 230 It is injected.

The sealing means blocks the drug leakage between the main handle 100 and the auxiliary handle 200 when the drug is injected through the drug injection unit 130 in a state in which the main handle 100 and the auxiliary handle 200 are coupled to each other. Do it.

4A and 4B, the configuration of one embodiment of the sealing means will be described in detail. An inclined surface 122 tapered inward is formed on the upper surface of the needle insertion part 120 formed on the main handle 100. Then, the O-ring 240 is fitted to the drill needle 210 fixed to the lower side of the auxiliary handle 200, the O-ring 240 is mounted in contact with the bottom surface of the needle mounting portion 220. That is, the O-ring 240 is in close contact between the inclined surface 122 and the needle mounting portion 220 when the main handle 100 and the auxiliary handle 200 are coupled, whereby the drug injected through the drug injection unit 130 is The needle insertion unit 120 is prevented from leaking through the hole in the center.

5A and 5B illustrate a structure of another embodiment of the sealing means, and the outer circumferential surface of the needle inserting portion 120 'formed on the main handle 100 is formed in a smooth pattern. In addition, the needle mounting part 220 'protrudes to form a lower portion of the auxiliary handle 200 so as to be firmly fitted to the outer peripheral surface of the needle insertion part 120', and further extends around the needle mounting part 220 'downwardly. . That is, when the main handle 100 and the auxiliary handle 200 are combined, the inner peripheral surface of the needle mounting part 220 'is fitted to the outer circumferential surface of the needle insertion unit 120' in a compressed state, thereby being injected through the drug injection unit 130. The drug is not leaked through the hole in the center of the needle insert 120 '.

Referring to the operation and effect of the present invention configured as described in detail as follows.

The needle for spinal surgery of the present invention is used in surgery related to vertebral bone procedures such as bone marrow examination and bone marrow extraction procedures related to bone marrow transplantation as well as bone cement injection procedures related to spinal surgery.

Thus, when the bone marrow transplantation and bone marrow transplantation for the bone marrow transplant for example described more specifically the use of the present invention, first the local anesthesia on the part of the skin of the patient to be treated, the main handle 100 and the auxiliary handle Pressing the punching needle 210 protruding from the state in which the 200 is coupled to the skin to puncture the skin.

Afterwards, when the end portion of the puncture needle 210 comes in contact with the vertebral spine as shown in FIG. 7A, the cap 132 that controls the drug injection unit 130 is opened, and the syringe is filled with an anesthetic. Anesthesia fluid is injected into the drug injection unit 130. The anesthesia solution injected in this way is supplied to the space portion 140 inside the main handle 100, and the anesthetic solution supplied in the space portion 140 immediately flows along the injection groove 230 formed in the puncture needle 210. While being guided to the end of the puncture needle (210) in contact with the patient's sacrum spine, it is possible to anesthetize the sacrum spine to collect bone marrow.

At this time, between the needle insertion portion 120, 120 'of the main handle 100 and the needle mounting portion 220, 220' of the auxiliary handle 200 is kept closed by a sealing means, the space portion 140 Anesthesia solution injected into the can flow stably along the injection groove 230 without leaking.

When the anesthesia of the sacrum spine is made in this manner, as shown in FIG. 7B, a stronger pressing force or a hammer hits the upper portion of the auxiliary handle 200 through a hammer to puncture the sacrum spine. Thereafter, when the end of the injection pipe 110 outside the puncture needle 210 is embedded in the bone marrow inside the vertebral spine, the auxiliary handle 200 is separated from the main handle 100 through the rotation operation of the auxiliary handle 200. Let's do it. Then, the cap 132 is sealed on the drug injection unit 130 and sealed, and as shown in FIG. 7C, an empty syringe is inserted into the needle insertion unit 120 and 120 ′ above the main handle 100 to inhale the bone marrow. It is possible to collect.

As such, the needle for spinal surgery of the present invention can inject anesthesia along an injection groove 230 formed in the puncture needle 210 to penetrate the vertebrae to be punctured while penetrating the skin. The patient's pain can be significantly reduced.

In other words, the conventional vertebrae perforation needle has a fatal problem that the patient has to bear all the extreme pain that the bone is drilled because there is no means to anesthetize the vertebrae, the needle for spinal surgery of the present invention By performing anesthesia by directly administering anesthesia solution to the vertebrae to be drilled before, the patient's pain can be reduced as much as possible, thereby reducing the fear and rejection of the procedure and providing a comfortable treatment environment for both the operator and the patient.
