Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Firstly, in order to facilitate understanding of the tumor sampler for breast surgery provided in the embodiment of the present application, an application scenario of the tumor sampler for breast surgery is explained first, and the tumor sampler for breast surgery in the embodiment of the present application fixes a conventional sampler unstably, thereby enhancing pain; and the defects of easy blood mixing in the sampling process are overcome.
The tumor sampler for breast surgery provided by the embodiment of the present application is described below with reference to the accompanying drawings.
Referring collectively to fig. 1-2, a tumor sampler for breast surgery in an embodiment of the present application includes: the sampling sleeve 1 is taken as a sleeving assembly in the embodiment of the application, the upper part of the sampling sleeve 1 is a holding part 4, the holding part 4 is convenient for a sampling person to hold with one hand, and the holding part 4 is alternately provided with stripe bulges 5 for preventing the medical person from sweating and slipping when holding with the hand;
simultaneously in order to guarantee the stability of this sampling device when using, fixed cover is equipped with ring 7 on sampling sleeve 1, and the equidistant interval in its circumference is provided with the auto-lock pivot 9 that is used for assembling corresponding supporting leg 8 on ring 7. The supporting legs 8 are in triangular distribution, and each supporting leg 8 is rotated and locked at a set angle through a self-locking rotating shaft 9, so that powerful support is formed, and shaking in the sampling process is avoided;
meanwhile, one end, far away from the circular ring 7, of each supporting leg 8 is hinged with a supporting block 10, and the lower surface of each supporting block 10 is a silicone rubber layer 11. The supporting block 10 is hinged with the supporting leg 8 through a rotating shaft, and the silicon rubber layer 11 increases friction force when contacting with human skin or clothes, so that the stability is better;
fig. 2 is a schematic diagram of the embodiment of the present application during sampling, a sampling needle rod 2 is slidably disposed in a sampling sleeve 1, an upper portion of the sampling needle rod 2 is sleeved in the sampling sleeve 1, a lower portion of the sampling needle rod 2 is a rod body with a smaller diameter than the upper portion, and the upper portion and the lower portion of the sampling needle rod 2 are of an integrated structure; the top end of the sampling needle rod 2 is provided with a handle 3, and the bottom end of the sampling needle rod 2 is sleeved with a separable sampling needle head 13; and the sampling needle rod 2 is provided with a hollow cavity 16;
in order to prevent blood from mixing with the excised tumor sample in the sampling process, a spring button 6 is arranged in the middle of the handle 3, the spring button 6 is connected with a sampling needle 13 through a push rod 15 positioned in a hollow cavity 16, and the connecting part of the sampling needle 13 and the sampling needle rod 2 is an annular blade 14.
Specifically, the middle part of the handle 3 is provided with a mounting hole communicated with the hollow cavity 16, and the spring key 6 is correspondingly assembled in the mounting hole. The spring key 6 is reset by the elasticity of a compression spring, and the specific structure is a common technical method in the prior art, which is not described herein;
furthermore, a graduation mark 12 is provided on the sampling needle rod 2 for the purpose of accurately connecting the penetration depth.
With continued reference to fig. 3, and in order to prevent the sampling needle 2 from being out of control in pushing down or retracting, a sealing ring 17 is fitted over the sampling needle 2 to rub against the inner wall of the sampling sleeve 1. Thereby increasing the friction force between the sampling needle rod 2 and the sampling sleeve 1, leading the moving speed to be more convenient to master, being capable of slowly pushing or withdrawing, and reducing the pain.
In the above structure, it can be seen that, when sampling, the supporting leg 8 is supported at a proper angle, the medical staff holds the hand holding part 4 with one hand and holds the handle 3 with the other hand, the sampling needle rod 2 is pushed down, the sampling needle 13 slowly enters the inside of the tumor part, the penetration depth is clearly known through the scale 12, meanwhile, the thumb of the hand holding the handle 3 is used for pressing the spring key 6, the spring key 6 drives the push rod 15 to press downwards, a certain gap is formed between the sampling needle head 13 and the sampling needle rod 2, the tumor medium has certain elasticity, part of the tumor medium can be extruded into the gap, the upper part of the sampling needle head 13 is provided with an annular blade 14, after the thumb releases the spring button 6, the sampling needle 13 is recovered, the tumor medium in the gap is cut off, and the sample is completely stored in the hollow cavity 16, so that the mixing of external blood is avoided, the sampling process is simple and convenient, and certain practical value is achieved.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
