Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a device for treating bone diseases,
In particular, the present invention relates to a bone disease test or treatment instrument and a bone disease treatment instrument which are effective in the examination or treatment of bone cysts.

[0002]

2. Description of the Prior Art As a bone tumor-like disease, serous fluid is retained in the bone, the sea surface bone structure in the marrow is destroyed, and the cortex becomes thin,
There is a bone disease called bone cyst that results in pathological fractures. Bone cysts have been treated as tumor-like diseases in the same manner as benign tumors, and lesion curettage and autologous bone (in some cases, allogeneic bone graft) transplantation have been performed. In 1974, it was reported by Scaglietti that a large number of small holes were made in a bone cyst and that injection of a steroid drug could cure the bone cyst with a probability of 90% or more. After that, it was also reported by De Paima and Pentimalli that bone cysts that seemed to heal once had a defect of recurring at a frequency of 40% to 70%. Furthermore, with the aim of eliminating this recurrence, Santori has newly started a method of piercing Kirschner steel wire from the lesion into normal bone marrow. This steel wire insertion method is simple and a slight gap is formed around the steel wire due to the difference in elastic modulus between the steel wire and the bone, and the intramedullary pressure in the bone is continuously released from this portion, and it is considered to be an effective treatment method. Has been.

[0003]

The lesion curettage / autologous bone transplantation method described above collects bone from a living body under general anesthesia and implants it in the lesion site of the curettage, which is highly invasive to the patient and can cause recurrence. There was a nature. Steroid injection is simple and minimally invasive, but has an extremely high recurrence rate (40
% To 70%), and it was necessary to repeat the process many times.

The steel wire puncturing method may be performed once, but it is a very inefficient method for decompressing the intramedullary pressure, and it has a drawback that it takes a long time to cure a cyst. Since it is necessary to pierce the tip into normal bone marrow, under local anesthesia, the needle is pierced to an unanesthetized site, causing problems such as pain to the patient, and the tip of the steel wire buried under the skin. There are problems that the surrounding tissue is stimulated to cause local pain, and that the tip of the steel wire comes out of the bone and damages nerves and blood vessels.

Further, it is necessary to collect the intraosseous fluid (bone marrow fluid) in order to judge the pathological condition of the bone disease, but there has been no device capable of simply collecting the intraosseous fluid (bone marrow fluid).

An object of the present invention is to provide a bone disease treatment tool and a bone disease treatment which can perform bone disease treatment such as bone cysts with minimal surgical invasion and without the above problems. A tool for use is provided. Further, an object of the present invention is to provide a device for examining a bone disease, in which bone fluid can be easily collected.

As shown in FIG. 6, when bone marrow fluid for examination of bone diseases was collected using the therapeutic instrument 1, if it seems to be a bone cyst, to reduce the continuous intramedullary pressure in the bone, Then, the second treatment device 5 is attached to the bone. First, the syringe of the treatment instrument 1 is removed, the guide wire is inserted again into the treatment instrument 1, the guide wire (not shown) is maintained as it is, and only the treatment instrument 1 is removed from the bone. Then, along the guide wire, the therapeutic instrument 5 is guided to the hole formed by the therapeutic instrument 1, the tip portion 55 is inserted into the hole, and then the guide wire is pulled out to the rear end of the therapeutic instrument 5. A jig (not shown) is attached and rotated, and the thread of the therapeutic instrument 5 is screwed into the thread groove formed in the bone by the therapeutic instrument 1. Then, the incision is sutured to complete the procedure.

This state is shown in FIG. Since the inside of the bone and the outside (muscle 32) are communicated with each other by the therapeutic device 5, even if the intramedullary pressure increases due to the bone cyst, the pressure leaks to the outside of the bone and decreases, so Intramedullary pressure can be reduced. In addition, since a suture mark remains on the skin surface of the site where the therapeutic instrument 5 is embedded, it is easy to confirm the site where the therapeutic instrument 5 is embedded. By reaching the posterior end opening, it is possible to inject a drug into the bone, which is also effective for treating bone diseases such as osteomyelitis. As described above, the continuous intramedullary pressure in the bone can be surely reduced, the treatment period can be shortened as compared with the conventional steel wire puncture method, and further, the treatment instrument 5 has the embedded portion. There is less irritation under the skin and less pain to the patient.
