Abstract
The invention discloses a centrum tumor remover. The centrum tumor remover comprises a handheld end and a sampling end, wherein the handheld end is connected with the sampling end. The sampling end is a cylindrical barrel which is axially provided with an axial opening in the wall thickness direction, and a cavity is formed in the middle of the cylindrical barrel. The inner cylindrical surface and the outer cylindrical surface of the tail end, namely the sampling end, of the cylindrical barrel, are connected through an outwards-protruding first transition circular arc, so that a first cutting edge bending inwards is formed at the tail end of the cylindrical barrel. The centrum tumor remover is simple and compact in structure, convenient to sample, high in reliability, small in cutting force and wound and trauma and beneficial for wound healing.
Description
Technical field
The present invention relates to medical apparatus and instruments technical field, particularly a kind of vertebral body gets tumor device.
Background technology
Adopt in prior art and get the less sampling of tumor pincers, owing to being subject to the restriction of skin and pediculus arcus vertebrae boring diameter dimension, jaw opening angle is less, the gripping power of jaw is also less simultaneously, the sample that can cut is fewer, and sample is easily trapped in focal zone and causes sampling amount not enough, the accuracy of impact test and testing result, the position simultaneously stretched into due to sleeve portion is restricted, be not easy after jaw puts in reach predetermined lesions position, easily cause sampling inaccurate, cause the deviation of testing result large, even need secondary sample, repeat to cause wound, added burden and risk is all brought to patient and medical worker.
Summary of the invention
Object of the present invention is exactly the problems referred to above existed for solving prior art, provides a kind of vertebral body to get tumor device; Structure of the present invention is simple, compact, and sampling is convenient, reliability is high, and cutting force is little, wound wound is little, is conducive to wound healing.
The technical scheme of technical solution problem of the present invention is:
A kind of vertebral body gets tumor device, comprise the handheld terminal, the sampling end that are connected, described sampling end is for be provided with axially open vertically in wall thickness direction, centre is the cylinder barrel of inner chamber, namely the end of described cylinder barrel samples the inner cylinder face of the end of end and external cylindrical surface and adopts First Transition circular sliding slopes to evagination, makes the end of cylinder barrel form aduncate first blade.
Described axially open angle is 90 °.
The end face of described wall thickness direction axially open is that inner cylinder face is connected by the second transition arc transition to evagination with external cylindrical surface, makes axially open form aduncate second blade.
The adjacent upper part of described cylinder barrel end is provided with the projection bent inwards vertically, and described raised brim stretches in cylinder barrel inner chamber.
The bending angle of described projection is 45 °.
Described first blade adopts zigzag structure.
Beneficial effect of the present invention:
1. structure of the present invention is simple, compact, and sampling is convenient, reliability is high, and cutting force is little, wound wound is little, is conducive to wound healing.
2. adopt this angle, preferably cutting effect can be reached, and successfully can take out the sample body of requirement.
By being provided with the first blade, the second blade, the resistance of cutting can be reduced, reducing cutting wound area, accelerating wound.
3. by arranging this projection, sample body enters to be got tumor device postadhesion and is getting in the inner chamber in tumor device, when pulling out, due to the barrier effect of this projection, prevent sample body from departing from the inner chamber got in tumor device, being trapped in vertebral body, primary sample just can ensure the quantity that sample body withdrawal amount meets test and detects.
4. the first blade adopts zigzag structure, rotating and getting tumor device and cut focal zone, can reduce Cutting Drag, also can reduce the wound of cutting, be conducive to wound healing when sampling.

Detailed description of the invention
In order to understand the present invention better, explain embodiments of the present invention in detail below in conjunction with accompanying drawing.
As shown in Figures 1 to 4, a kind of vertebral body gets tumor device, comprise the handheld terminal 1, the sampling end 2 that are connected, described sampling end 2 is for be provided with axially open 28 vertically in wall thickness direction, centre is the cylinder barrel of inner chamber 31, the inner cylinder face that namely end 22 of described cylinder barrel samples the end of end adopts the First Transition circular arc 24 to evagination to be connected with external cylindrical surface, makes the end 22 of cylinder barrel form aduncate first blade 26.
Described axially open angle a is 90 °.Adopt this angle, preferably cutting effect can be reached, and successfully can take out the sample body of requirement.
The end face 21 of described wall thickness direction axially open 28 is that inner cylinder face 30 is connected by the second transition arc 23 transition to evagination with external cylindrical surface 29, makes axially open form aduncate second blade 27.By being provided with the first blade 26, second blade 27, the resistance of cutting can be reduced, reducing cutting wound area, accelerating wound.
The adjacent upper part of described cylinder barrel end 22 is provided with the projection 25 bent inwards vertically, and described raised brim stretches in cylinder barrel inner chamber.The bending angle of described projection is 45 °.By arranging this projection, sample body enters gets tumor device postadhesion in the inner chamber 31 got in tumor device, when pulling out, due to the barrier effect of this projection, prevent sample body from departing from the inner chamber 31 got in tumor device, being trapped in vertebral body, primary sample just can ensure the quantity that sample body withdrawal amount meets test and detects.Protruding 25 as far as possible close to cylinder barrel end 22 and blade edge position.
Described first blade 26 adopts zigzag structure, rotating and getting tumor device and cut focal zone, can reduce Cutting Drag, also can reduce the wound of cutting, be conducive to wound healing when sampling.
During use, first upon connection the rear of the cone-plate on limit, the pedicle of vertebral arch of vertebral body in front utilizes drill bit to pediculus arcus vertebrae boring, after boring hole in lay abutment sleeve, getting tumor device from the endoporus of abutment sleeve through entering tumor area, being issued to predetermined lesions position at x-ray, drawing materials.Take out being attached to the material sample got in tumor device.
By reference to the accompanying drawings the detailed description of the invention of invention is described although above-mentioned; but not limiting the scope of the invention; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection scope of the present invention.
