Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical instruments, in particular to an intraoral puncture needle. Background Art
[0002] A puncture needle is usually a rigid tube with a sharp tip and is a medical device. It is mainly used to puncture parts of the human body to collect tissue samples or as a channel for other instruments to enter the body.
[0003] The needle tube of the existing medical puncture needle is fixed into one by a metal tube and a polymer material needle holder, and scale lines are set on the surface of the needle tube, so that medical staff can grasp the puncture depth in time when puncturing the patient. For example, Chinese utility model patent CN202288414U discloses a scale puncture needle, which is convenient for medical staff to determine the puncture depth by setting different scales. However, the scale lines of the existing puncture needles are usually single black scale lines. After puncturing into the human body, doctors often forget the depth of the needle, which can easily lead to misjudgment. In addition, when puncture is required in the oral cavity, since the light in the oral cavity is relatively dim, the assistance of an external light source is often required, so additional lighting is required, and the dim light in the oral cavity is not conducive to medical staff reading the scale on the surface of the puncture needle, and the puncture depth cannot be grasped in time.

[0023] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and a specific operation process, but the protection scope of the present invention is not limited to the following embodiments.
[0024] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to specific circumstances.
[0025] In addition, the terms "installed", "set", "provided with", "connected", "connected", and "socketed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0026] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0027] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0028] Example 1
[0029] like Figure 1 As shown, the utility model provides an intraoral puncture needle, comprising an operating handle 1 and a needle body 2 mounted on the operating handle 1 , wherein an inner needle is movably arranged in the needle body 2 .
[0030] like Figure 2 As shown, in order to provide lighting, a power supply is provided inside the operating handle 1, and a toggle switch 3 is provided on the surface of the operating handle 1. The toggle switch 3 in the present embodiment is a waterproof switch. A lighting lamp is provided around the end surface of the operating handle 1 on which the needle body 2 is installed. The specific lighting lamp is an LED lamp bead 4 provided around the needle body 2. The power supply, the toggle switch 3 and the lighting lamp are circuit-connected in sequence.
[0031] like Figure 3 As shown, the surface of the needle body 2 is provided with scale lines 5 of different colors. In this embodiment, the width of the scale lines 5 is 4 mm, and the spacing between adjacent scale lines 5 is 1 cm. Specifically, the colors of the scale lines 5 in this embodiment are purple, blue, cyan, green, yellow, orange, and red from bottom to top. The colors of the scale lines gradually become eye-catching from light to dark, which plays a better reminder role for medical staff.
[0032] When the puncture needle of the utility model enters the oral cavity, the puncture position can be quickly found by the illumination lamp, and during the puncture process, the medical staff can quickly determine the puncture depth by observing the color of the nearest scale exposed outside the skin epidermis.
[0033] Example 2
[0034] The difference between this embodiment and embodiment 1 is that the scale lines 5 of different colors in this embodiment are made of fluorescent materials of different colors, and the scale lines 5 are specifically configured as follows: a scale groove is processed on the surface of the needle body 2 by laser engraving, a rare earth fluorescent material is coated in the engraved scale groove, and finally a transparent medical epoxy resin is filled in the scale groove.
[0035] The advantage of doing so is that the fluorescent material in the scale lines 5 reflects light of different colors, thereby making the scale lines 5 more obvious, more suitable for use in a dim oral cavity, and facilitating quick viewing by medical staff.
[0036] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
