Detailed Description
Example one
The invention discloses a skin perforation blunt needle device which comprises a stainless steel needle tube 1, a handle 6 and a needle tube protective sleeve, wherein one end of the stainless steel needle tube 1 is fixed on the handle 6, and the other end of the stainless steel needle tube 1 is a puncture needle head. A needle cannula protecting sleeve (not shown) is sleeved outside the needle cannula and covers the handle 6 tightly. One end of the stainless steel needle tube 1, which is far away from the handle 6, is provided with a hemispherical blade surface 2, the top of the spherical surface of the stainless steel needle tube 1 is provided with an inward concave blade 4, and the inward concave blade 4 and the central axis of the needle tube form an acute angle of 10-80 degrees. The hemispherical blade face 2 replaces the sharp-angled shape of the known puncture needle, the concave blade edge 4 is used as a blade for cutting the skin, and the stainless steel needle tube 1 is smoothly led into the puncture needle after the skin is cut.
For smooth puncture, the hemispherical blade surface 2 is provided with an inclined surface 3, and the inclined surface 3 is provided with two inward-concave blade edges 4 which are symmetrically arranged at two sides of the inward-concave blade edge 4 by taking the inward-concave blade edge 4 as an axis. The inclined plane 3 and the central axis of the needle tube form an included angle of 10 degrees to 50 degrees, the vertex of the included angle is close to the top of the spherical surface, the inclined plane 3 is in a water drop shape, and the tip of the inclined plane is positioned at one end far away from the hemispherical blade surface 2. In the process that the concave knife edge 4 is pushed into the stainless steel needle tube 1 after being used as a knife edge for cutting skin, the inclined plane 3 can effectively increase the puncture force for sliding under the skin without puncturing subcutaneous tissues and capillary vessels, thereby being convenient for operation and ensuring the operation safety. The stainless steel needle tube 1 is provided with a groove 5 positioned at the bottom of the concave knife edge 4, and the groove 5 is communicated with the stainless steel needle tube 1. The groove 5 can be used for placing a wire and fixing the wire on one side during subcutaneous catgut embedding operation, so that the operation of doctors is facilitated.
The handle 6 is provided with a wing-shaped operating part 61, and one end of the handle 6 far away from the stainless steel needle tube 1 is provided with a luer 62 for connecting with a syringe. The wing-shaped operating part 61 facilitates the holding and rotation of the stainless steel needle tube 1 during the operation in the skin, and the luer 62 at the tail part is designed to be connected with a syringe and the like, thereby facilitating the subcutaneous injection of liquid medicine or the suction operation.
Example two
The invention discloses a skin perforation blunt needle device, which is different from the first embodiment in that: on the structure basis of embodiment one, establish retainer plate 7 in handle 6 overcoat, be connected with flexible stretch cord 71 on retainer plate 7, the one end that flexible stretch cord 71 kept away from retainer plate 7 is provided with silica gel sleeve 72, flexible stretch cord 71 and silica gel sleeve 72 integrated into one piece. In this embodiment, the fixing ring 7 may be fixed outside the handle 6 by glue, and may be detachably mounted on the handle 6. The silica gel sleeve 72 is sleeved on the stainless steel needle tube 1 and is in interference fit with the stainless steel needle tube 1. Because the special material of silica gel sleeve 72, can produce the resistance when sliding silica gel sleeve 72 along silica gel sleeve 72 to reach the effect of injecing silica gel sleeve 72 position under no external force effect. The silica gel sleeve 72 is provided with the anti-slip protrusion 73, so that the friction coefficient between a hand and the silica gel sleeve 72 is improved, and the operation is more convenient when the silica gel sleeve 72 needs to be moved.
When the silica gel sleeve 72 is sleeved on the hemispherical blade surface 2, the flexible elastic rope 71 is in a state of being straightened and having no resilience force. That is, when the silicone sleeve 72 slides to completely cover the hemispherical blade surface 2, there is no resilience force from the flexible elastic cord 71, and when the silicone sleeve 72 is moved by an external force to separate from the stainless steel needle tube 1 by the needle, a pulling force from the flexible elastic cord 71 is generated to prevent the flexible elastic cord from separating from the stainless steel needle tube 1. Therefore, the silicone sleeve 72 can be relatively safely sleeved on the stainless steel needle tube 1. On one hand, the length of the silicon rubber sleeve 72 which penetrates into the skin can be limited when the silicon rubber sleeve is sleeved in the middle of the stainless steel needle tube 1, and the risk of too deep penetration caused by operation error is reduced. On the other hand, in the operation process, the silica gel sleeve 72 can be moved temporarily to be sleeved on the concave knife edge 4, so that the effects of protecting the needle and preventing pollution are achieved.
The stainless steel needle tube 1 is provided with scales 74 along the axial direction thereof, and the silica gel sleeve 72 is a transparent sleeve. The scale 74 can be observed through the transparent sleeve in the process of moving the silica gel sleeve 72 to determine the final moving position, so that the puncture range is not limited by the silica gel sleeve 72 in the process of puncture surgery, and the puncture is not too deep due to misoperation.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
