In addition, with the advent of an aging society, chronic wounds (diabetic wounds, bedsores, venous ulcers, and the like) are increasing. The wound healing can be accelerated by accurately injecting drugs or human autologous cells or growth factors. This requires more accuracy in injection depth.
SUMMERY OF THE UTILITY MODEL
The present invention is made to solve the above problems, and an object of the present invention is to provide an injection needle capable of controlling and displaying an injection depth, which can precisely adjust the injection depth so that a medicine can reach a desired target point.
In order to achieve the above purpose, the utility model discloses there is following technical scheme:
the invention relates to an injection needle capable of controlling and displaying injection depth, which comprises a needle body and a needle point, wherein the needle body and the needle point are integrated structures formed by stainless steel materials, and also comprises a nested part, a screw rod and a sleeve, the nesting part is used for being connected with an injector, one side of the tail end of the needle body passes through an axial line hole in the screw rod, is communicated with the nesting part, one end of the screw rod is connected with the nesting part, the other end of the screw rod is connected with the internal thread end of the sleeve through the external thread of the screw rod, the sleeve is wrapped on the periphery of one side of the needle tip of the needle body, the needle body is of a hollow structure, the needle tip end of the needle body is positioned at the through hole of the needle outlet end of the sleeve, the nested part, the needle body and the needle tip are of hollow structures which are communicated continuously, the medicine of the injector can pass through the hollow structures, the needle tip of the needle body can be controlled to be exposed to different lengths by the spiral rotation of the sleeve on the spiral rod.
Wherein, nested portion, hob are the plastics material, the needle body leans on tail end one side to have 1/2's length to alternate in the hob, the needle body is connected with the inside axis hole close fit of hob or is connected through glue.
The needle comprises a needle body, a needle outlet end, a sleeve, a scale and a needle outlet end, wherein the sleeve is made of transparent plastic, the length of 1/2 on one side of the needle body close to the needle tip is located in the sleeve, the surface of the sleeve is provided with a scale ruler, and the scale marks from the inner thread end of the sleeve to the needle outlet end of the sleeve in millimeters; the point where the cannula overlaps the screw rod is shown as the specific depth of injection. Because of the restriction of the cannula to the needle, the depth of injection can be controlled.
Wherein, the intersection point of the screw rod and the sleeve displays 0 scale; the scale on the surface of the sleeve starts from 0 to the needle outlet end of the sleeve, and the needle outlet end of the sleeve is flush with the needle point; when the sleeve rotates towards the nesting part, the intersection point of the end part of the screw rod and the sleeve is the depth capable of being injected; because of the cannula control, only the exposed needle and needle tip can be injected into the skin.
Owing to adopted above technical scheme, the utility model has the advantages of:
according to the injection needle of the invention, the injection depth can be displayed and controlled. Therefore, the injection needle head of the invention can ensure that the medicine can accurately enter the position to be reached, thereby increasing the accuracy of the medicine reaching the injection target point, being capable of injecting the medicine at the same level in multiple points, adjusting the injection depth according to the requirement and increasing the safety and the effectiveness of injection.

Detailed Description
The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
Referring to fig. 1:
the utility model relates to an injection needle capable of displaying and controlling injection depth. The needle body and the needle point are integrally formed by stainless steel materials.
The utility model discloses a steerable and syringe needle that shows injection depth, including needle body, needle point, needle body, needle point adopt stainless steel material to form an organic whole structure, and the needle point hypotenuse is 30 degrees contained angles with the vertical axis of needle body, still includes nested portion, hob, sleeve pipe, nested portion is used for linking to each other with the syringe, needle body tail end passes behind the axis hole of hob inside on one side, communicates with nested portion, and one end and the nested portion of hob are connected, and the other end of hob passes through the external screw thread of hob and is connected with the sheathed tube internal thread end, and the sleeve pipe wraps up in the periphery of needle point tip one side, the needle body is hollow structure, and the needle point of needle body is located the through-hole department of sleeve pipe play needle end, and nested portion, needle body, needle point inside are continuous communicating hollow structure, and the medicine of syringe can pass through in hollow structure, through the spiral rotation on the hob through, the needle tip of the needle body can be controlled to be exposed to different lengths.
Nested portion, hob are the plastics material, the needle body leans on tail end length that has 1/2 on one side to alternate in the hob, the needle body is closely connected or is connected through glue with the inside axis hole of hob in a matched manner.
The sleeve is made of transparent plastic, the length of 1/2 on one side of the needle body close to the needle tip is positioned in the sleeve, a scale is arranged on the surface of the sleeve, and the scale marks in millimeters from the inner thread end of the sleeve to the needle outlet end of the sleeve; the point where the cannula overlaps the screw rod is shown as the specific depth of injection. Because of the restriction of the cannula to the needle, the depth of injection can be controlled.
