Abstract
The invention discloses a percutaneous threaded marrow core bone tumor biopsy puncture needle. The percutaneous threaded marrow core bone tumor biopsy puncture needle comprises a threaded biopsy extractor, a cancellous bone way opening needle, a holding handle, an opening forming needle, a pushing rod, a first sleeve and a second sleeve. The cancellous bone way opening needle and the opening forming needle are both stylets with sharp bottoms. The opening forming needle goes deep into the holding handle, and the opening forming needle and the holding handle are combined into a puncture needle body. According to the percutaneous threaded marrow core bone tumor biopsy puncture needle, a special bone window opening tool is arranged, window opening can be easily conducted on the cortex of a bone and the spongiosa of the bone, the puncture needle can reach a diseased region, and the problem that other puncture needles cannot be used for conducting biopsy in the bone or are used for conducting biopsy in the bone difficultly is solved. If a window formed in sclerotin is too large, the pushing rod of the puncture needle can be used for implanting a bone block back through the first sleeve or the second sleeve, and therefore a bony defect is prevented from being too large. After the puncture needle reaches diseased tissue, threads can be screwed in easily to cut the diseased tissue, the screw-in depth can be decided at will, the screws can be directly taken out after sampling is completed, other devices such as a negative-pressure device is not needed, the diseased tissue is easy to collect, and the damage to peripheral tissue is small.
Description
Technical field
The invention belongs to medical instruments field, relate in particular to a kind of percutaneous screw thread marrow arbor tumor biopsy puncture needle.
Background skill is stated
Bone tumor is the tumor that betides skeleton Huo Qi affiliated group, is clinical common a kind of disease.The preoperative unique channel of obtaining disease sample material is biopsy, is therefore guaranteeing, under safe prerequisite, to obtain as far as possible more specimen, very important to improving biopsy diagnosis accuracy like this.At present bone tumor puncture needle mainly contains the Biomid Trocar puncture needle of Italian GALLINI company, German Ackeman pin etc., and this class pin mostly is the percutaneous trocar, adopts core aspiration biopsy or negative pressure absorbing.Similarly also have the bullet of U.S. Cook company, German Angiomed company to rob formula biopsy needle etc.At present the problem of bone aspiration biopsy maximum be the specimen obtaining organize very little, unilateral, cannot diagnose, even mistaken diagnosis, cause one of the main reasons that biopsy is few be the tissue of biopsy needle to cut structure be concave groove type, groove is too little; Or barb-shaped, can not go out abundant pathological tissue by hook; Or for core puncture, usually can not completely take out.
Puncture and obtain more pathological tissue, can adopt thicker puncture needle to obtain more tissue, also can be in the best aspect multiple spot puncture of puncturing.But these methods are larger to tissue injury, also increasing of the number of times of drawing materials may cause bleeding, infect, and increases patient painful.
Summary of the invention
The object of the present invention is to provide a kind of percutaneous screw thread marrow arbor tumor biopsy puncture needle, be intended to solve extraction biopsy that existing bone tumor biopsy needle exists very little, need negative pressure device to support the use and sampling process to the larger problem of pathological tissues damage.
The present invention is achieved in that a kind of percutaneous screw thread marrow arbor tumor biopsy puncture needle comprises seven assemblies: 1. screw thread biopsy extraction apparatus; 2. spongy bone open circuit pin; 3. help handle; 4. opening pin; 5. pushing ram; 6. the first sleeve; 7. the second sleeve.Described spongy bone open circuit pin and opening pin are point end nook closing member; Described opening pin is deep into be helped in handle, and both are combined to form puncture needle.
Further, the far-end 2cm place of described screw thread biopsy extraction apparatus is provided with deep thread, flat.
Percutaneous screw thread marrow arbor tumor biopsy puncture needle of the present invention is equipped with the special window instrument that opens seam, and can easily cortical bone and spongiosa be windowed, and arrives diseased region.Solved the difficult problem that other puncture needle can not or be difficult to do biopsy in bone, too large if sclerotin is windowed, can use the pushing ram of this device through the first sleeve or the second sleeve, bone piece Hui Zhi to be got on, avoid bony defect too large; Arrive the precession easily of pathological tissues rear thread and cut pathological tissues, screw-in depth can freely determine, sampling finishes directly to take out, do not need other devices such as negative pressure; pathological tissues collection method is simple; the damage to surrounding tissue is little, and can obtain the pathological tissue of different depth simultaneously, significant to the analysis of tumor.

The specific embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with embodiment and accompanying drawing, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Fig. 1 to Fig. 7 has shown the modular construction of percutaneous screw thread marrow arbor tumor biopsy puncture needle of the present invention, and as shown in the figure, the present invention is achieved in that a kind of percutaneous screw thread marrow arbor tumor biopsy puncture needle comprises seven assemblies: 1. screw thread biopsy extraction apparatus; 2. spongy bone open circuit pin; 3. help handle; 4. opening pin; 5. pushing ram; 6. the first sleeve; 7. the second sleeve.Described spongy bone open circuit pin and opening pin are point end nook closing member; Described opening pin is deep into be helped in handle, and both are combined to form puncture needle.
Further, as shown in Figure 1, the far-end 2cm place of described screw thread biopsy extraction apparatus is provided with deep thread, flat.
Below in conjunction with drawings and the specific embodiments, application principle of the present invention is further described.
Opening pin shown in support handle shown in Fig. 3 and Fig. 4 is first combined and is formed puncture needle (nook closing member and outer sleeve), its end is sharp-pointed inclined-plane, after breaking through the soft tissues such as skin and muscle, directly arrive at cortical bone or spongy bone position, if because cortical bone or spongy bone are too hard, this puncture needle can not be broken through, can first with the spongy bone open circuit pin shown in Fig. 2, knock and crack cortex, then enter tumor tissues in bone with puncture needle.
Through feel or the lower definite puncture needle of perspective, arrive borderline tumor or enter in tumor tissues, take out immediately nook closing member, insert the screw thread biopsy extraction apparatus shown in Fig. 1, screw in gently, according to clinical requirement, the degree of depth that screw thread biopsy extraction apparatus shown in feel or the lower definite Fig. 1 of perspective enters tumor tissues, then takes out rapidly screw thread biopsy extraction apparatus, with injection needle, by being embedded in tumor tissues in the middle of screw thread, cleaning with a pointed instrument and collects good preservation.
If cortex punching place bony defect is many, can put at this position with the second sleeve shown in the first sleeve shown in Fig. 6 or Fig. 7, with the pushing ram shown in Fig. 5, push bone or replacement bone material to this position, avoid bony defect to cause too much complication, as pathological fracture etc.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
