Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reach object and effect is easy to understand, following examples are specifically addressed ejecting type bone aspiration biopsy surgical instrument assemblies provided by the invention by reference to the accompanying drawings.
As shown in Figure 1, the ejecting type bone aspiration biopsy surgical instrument assemblies that the present embodiment provides comprises reamer 1 and puncture biopsy needle 2.
Concrete, reamer 1 comprises: reaming pin 11 and the sleeve 12 be axially sleeved on reaming pin 11.Wherein, be matched in clearance between the medial wall of reaming pin 11 and sleeve 12.
In the present embodiment, the needle point of reaming pin 11 overhangs out sleeve 12, and the needle point position of reaming pin 11 is provided with helicitic texture 13.In addition, the needle handle 14 of reaming pin 11 and handle 15 tabling of sleeve 12 afterbody, thus reamer easy to use 1 pair of bone bed carries out ream operation.
Puncture biopsy needle 2 comprises: the operating grip 22 being provided with ejection mechanism 21, axially runs through the biopsy nook closing member 23 of operating grip 22, and is axially sheathed on biopsy nook closing member 23 outside and the Casing-Cutting 24 be flexibly connected with ejection mechanism 21.Further, the internal diameter of sleeve 12 is greater than the external diameter of Casing-Cutting 24, is convenient to the axially activity of Casing-Cutting 24 in sleeve 12.
As shown in Figure 2, in the present embodiment, the cutting tip of biopsy nook closing member 23 is closed inclined-plane, and biopsy nook closing member 23 offers the bar shaped biopsy groove 231 of hold bone myeloid tissue on the sidewall near cutting tip.In order to ensure to obtain quantitative myeloid tissue, in the present embodiment, the internal diameter of biopsy nook closing member 23 is preferably set to 2 millimeters, and, the length of bar shaped biopsy groove 231 is preferably set to 10 to 15 millimeters.
As preferred technical scheme, the cutting tip of Casing-Cutting 24 is opening bevel, and the length of biopsy nook closing member 23 is greater than the length of Casing-Cutting 24.Further, the incline direction on closed inclined-plane is contrary with the incline direction of opening bevel.
In addition, in the present embodiment, observe that biopsy nook closing member 23 stretches into the degree of depth in medullary cavity for the ease of operator, operating grip 22 is provided with the scale that do not show in figure and indicates, and this scale indicates and to overhang out the length of Casing-Cutting 24 cutting tip for showing bar shaped biopsy groove 231.
When the ejecting type bone aspiration biopsy surgical instrument assemblies using the present embodiment to provide carries out bone aspiration biopsy operation, first utilize reamer to carry out reaming to hard bone bed, can effectively avoid hard bone bed to damage biopsy nook closing member and Casing-Cutting.
Bone bed is after reaming, indicate according to scale, preset bar shaped biopsy groove to overhang out the length of Casing-Cutting, biopsy nook closing member and Casing-Cutting are integrally run through sleeve and stretches in medullary cavity, bar shaped biopsy groove due to biopsy nook closing member is exposed to the cutting tip of Casing-Cutting, thus the myeloid tissue in medullary cavity can be entered in bar shaped biopsy groove smoothly.
When the needle point of biopsy nook closing member enters into presetting position, press the eject button (not shown) of ejection mechanism, by the Casing-Cutting that launches, cutting and separating is carried out to the myeloid tissue entered in bar shaped biopsy groove outside myeloid tissue and bar shaped biopsy groove, and the myeloid tissue in bar shaped biopsy groove is closed, prevent from causing coming off of myeloid tissue extracting in puncture biopsy needle process, greatly can reduce the operation easier of bone aspiration biopsy operation, improve success rate of operation.
Certainly, ejecting type bone aspiration biopsy surgical instrument assemblies involved in the present invention is not merely defined in the structure in the present embodiment, any equivalent modifications of carrying out the present invention and substituting also all in category of the present invention.
