Abstract
The utility model provides a bone object is got to centrum of cooperation backbone scope system, including getting bone object body, get bone object body and be cylinder shaft-like structure, get the middle part of bone object body and seted up the location pinhole along the axial, the one end of getting bone object body is the hexagonal connector that links to each other with the handle, and the other end of getting bone object body is planar structure, just the plane department of getting the bone object body other end is fixed with gets the bone spirochaeta, gets the bone spirochaeta for the heliciform structure of getting bone object body length direction setting along, and the one end of getting the bone spirochaeta is fixed in and gets on the bone object body, and the other end of getting the bone spirochaeta is sharp taper structure. The device is a safe, simple and efficient instrument for establishing the bone channel, and enables an operator to reach the focus position more safely, conveniently and accurately in the operation process. Belongs to the field of medical operation instruments.
Description
Technical Field
The utility model relates to a bone ware is got to centrum of cooperation backbone scope system belongs to the medical treatment operating instrument field.
Background
When the disease in the vertebral canal is located on the ventral side of the spinal cord, the focus biopsy or the focus excision can be carried out only by establishing a working channel through the cervical vertebra, the thoracolumbar vertebra and the like, and the compression of spinal nerves is relieved. The conventional open operation has the defects of large wound, much bleeding and the like. In recent years, with the continuous development of percutaneous spinal endoscopy technology, the defects of open surgery can be avoided by establishing a bone working channel through a vertebral body under minimally invasive percutaneous puncture and C-arm monitoring. Under the prerequisite that the pathological change position is clear and definite to the image data before C arm perspective combines the art, with the help of supersound guide bone piercing depth, realize safe puncture, under the casing protection, place the trepan and establish working channel in the centrum, working channel's bone strip does not take out when taking out the trepan under the conventional condition, need look for again and use the abrasive drilling gradually to grind out the passageway along the vestige that the trepan left, it is very time-consuming like this, it is very inconvenient to use.
Disclosure of Invention
The utility model provides a device that is used for taking out bone strip through cervical vertebra, thoracic vertebra, lumbar vertebrae centrum and establishes osseous passageway and handle the focus ventral lesion that is located the spinal canal, its main aim at overcome and use high-speed evil spirit to bore the risk that the osseous working channel was taken time, complex operation and passageway easily deviate the focus through the centrum at present, provide the apparatus of a safe, simple and convenient, high-efficient bone passageway establishment technique, make the art person safe more in operation, convenient, the accurate focus position of reacing.
In order to solve the problems, the vertebral body bone taking device matched with the spinal endoscope system comprises a bone taking device body, wherein the bone taking device body is of a cylindrical rod-shaped structure, a positioning needle hole is formed in the middle of the bone taking device body along the axial direction, one end of the bone taking device body is a hexagonal connector connected with a handle, the other end of the bone taking device body is of a plane structure, a bone taking spiral body is fixed at the plane of the other end of the bone taking device body, the bone taking spiral body is of a spiral structure arranged along the length direction of the bone taking device body, one end of the bone taking spiral body is fixed on the bone taking device body, and the other end of the bone taking spiral body is of a pointed cone-shaped structure.
In the vertebral body bone taking device, the bone taking spiral body is of a triangular single spiral structure.
Compared with the prior art, the utility model discloses a to get bone ware head end and set up to triangular single heliciform, use red wine bottle-opener principle, when the trepan is rotatory to the centrum back wall, use and get the bone ware through the hollow rotatory centrum that gets into of trepan, get bone ware head end length 1.2mm,1.5mm, head end bottom parallel and level, can get into the centrum now the somatic part, safety when guaranteeing to rotate, the scale sign of somatic part guides and gets the degree of depth that the bone ware got into the centrum, get behind the bone ware entering centrum, the cooperation trepan just can take out the bone strip smoothly, establish working channel safely. After the trepan reaches the back edge of the vertebral body, the bone strip base part in the trepan is not broken, no embedded interaction exists between the periphery of the bone strip base part and the trepan, the trepan is exposed, the bone strip is not taken out, and a working channel is not successfully established.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a partial schematic view of the upper end of the bone extractor body;
fig. 3 is a schematic structural view of the lower end of the bone extractor body and the bone extracting screw body.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings.
Example (b):
referring to fig. 1 to 3, the present embodiment provides a vertebral body bone extractor cooperating with a spinal endoscope system, which includes a bone extractor body 1, the bone extractor body 1 is a cylindrical rod-shaped structure, a positioning needle hole 11 is axially disposed in the middle of the bone extractor body 1, one end of the bone extractor body 1 is a hexagonal connector 12 connected to a handle, the other end of the bone extractor body 1 is a planar structure, and a bone taking spiral body 2 is fixed on the plane of the other end of the bone taking device body 1, the bone taking spiral body 2 is of a triangular single spiral structure arranged along the length direction of the bone taking device body 1, one end of the bone taking spiral body 2 is fixed on the bone taking device body 1, the other end of the bone taking spiral body 2 is of a pointed cone structure so as to conveniently rotate into bone, get 1 other end parallel and level of bone object, can limit and prepare 1 entering centrum of bone object, avoid damaging the spinal cord because the head end gets into the vertebral canal.
Taking cervical spondylosis as an example, when a cervical spondylosis patient needs to perform anterior percutaneous positioning, firstly, a diseased segment is determined according to CT or MRI data, after a focus segment is positioned by a C arm during operation, a body surface mark is made, the segment is positioned and guided by an ultrasonic positioning probe according to the body surface, a safe puncture area is established in a gap between an esophageal visceral sheath and a vascular nerve sheath, and a puncture positioning needle is inserted along a central channel of the probe. The skin is broken by a positioning needle, an expansion sleeve and a protective sleeve are placed, a trepan is applied to a responsible vertebral body and is gradually screwed in to establish a working channel, when the C arm shows that the trepan position is clear from perspective to the rear edge of the vertebral body, the trepan is implanted into the vertebral body bone extractor through the trepan, the bone extracting spirochete 2 is screwed in the vertebral body, the trepan and the bone extractor are pulled out backwards under the protection of the sleeve according to the red wine bottle opener principle, bone strips are smoothly extracted, and the establishment of the vertebral body bone working channel is completed.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
