[0034] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0035] like Figure 1 As shown, this embodiment of the present invention provides a bone puncture needle, comprising:

[0036] Handle 1;

[0037] The needle body 2 has one end connected to the handle 1 and the other end forming a needle tip;

[0038] The needle body 2 has a clearance part 3 that can avoid obstacles in the puncture path. The needle body 2 is hollow in shape, and the handle 1 and the needle tip are connected inside the needle body 2.

[0039] For the bone aspiration needle of this embodiment, medical personnel can operate the handle 1, such as by rotating the handle 1, to allow the needle body 2 to enter the human body and perform bone aspiration. The needle body 2 in this embodiment is different from the conventional linear needle body 2. The needle body 2 in this embodiment has a clearance part 3, which can effectively avoid soft tissues, blood vessels and other obstructions in the human body during the process of moving to the target point of the bone and performing bone aspiration at the target point. This ensures that the needle body 2 will not damage soft tissues, blood vessels and other obstructions, and at the same time, the needle body 2 will not be affected by soft tissues and blood vessels. This ensures that the movement path of the needle body 2 in the human body (the pre-planned path for accurately reaching the target point) will not deviate.

[0040] Based on the above, the beneficial effects of this embodiment include a simple overall structure and ease of preparation of the bone puncture needle. By setting the needle body 2 to have a clearance part 3, it can effectively avoid obstacles such as soft tissue in the body when the needle body 2 penetrates into the human body to reach the target point and when performing bone puncture, without puncturing soft tissue and causing an increase in wounds. At the same time, it will not affect the deviation of the puncture path, so that the needle body 2 can accurately reach the target point along the pre-planned path, assisting medical personnel to perform bone puncture operations more smoothly, quickly and accurately.

[0041] In this embodiment, the needle body 2 and handle 1 can be integrally molded or independently set and then connected accordingly. The needle body 2 and handle 1 can be, but are not limited to, made of stainless steel. The handle 1 can be, but is not limited to, a straight line or other types. The needle body 2 is preferably located in the middle of the handle 1, i.e., the handle 1 and needle body 2 cooperate to form an approximately T-shaped structure. The needle body 2 and handle 1 can be fixedly connected or detachably connected. For example, the needle body 2 can have different sizes or different clearance parts 3 to avoid different obstacles, such as obstacles of different sizes and shapes. Medical personnel can then replace different needle bodies 2 as needed. The needle body 2 and handle 1 can be connected by a connection structure, such as a threaded connection structure, a snap-fit ​​connection structure, etc., the specifics are not fixed. Alternatively, the handle 1 can be telescopic, allowing its length to be adjusted as needed.

[0042] Furthermore, the needle includes one or more cutting edges for cutting or drilling. The specific structure of the needle is variable, as are the number and structure of the cutting edges, and can be adaptively adjusted according to actual cutting or drilling needs. The needle body 2 can be a solid needle body 2 or a hollow needle body 2, meaning the needle body 2 is entirely hollow. The needle body 2 can also be configured such that its hollow interior simultaneously connects to the handle 1 and the needle tip, allowing medical personnel to insert guide wires or other functional devices into the bone puncture needle to meet different surgical requirements.

[0043] Furthermore, in this embodiment, the needle body 2 comprises three parts: the first part forms the needle tip, the second part forms the clearance portion 3, and the third part is connected to the handle 1. That is, the needle body 2 is divided into three segments: one end of the first segment forms the needle tip, the other end is connected to the second segment, which forms the clearance portion 3, and the third segment is connected to the handle 1 and the second segment respectively.

[0044] Preferably, in practical applications, the length ratio of the first part, the second part and the third part is set to 2:4:4, which can cover a wide range of application scenarios.

[0045] Continue to combine Figure 1 As shown, both the first and third parts are straight lines and collinear. This arrangement allows medical personnel to adjust the operating handle 1 when using the bone puncture needle, and apply force to the third part using the handle 1 to simultaneously calibrate the first part, so that the needle can travel at the angle adjusted by the medical personnel.

[0046] Furthermore, in this embodiment, the avoidance portion 3 is formed by processing the second part of the needle body 2 into a meandering shape. That is, the avoidance portion 3 is not a straight line, but a structure that makes the second part of the needle body 2 meandering, for example, by being curved.

[0047] Specifically, in this embodiment, the second part of the needle body 2 is bent to one side to form the avoidance part 3. The specific degree of bending, bending area, bending shape, etc., are not fixed and can be determined according to the shape and size of the obstruction in the actual scenario.

[0048] In practical applications, the second part of the needle body 2 can be extended from the end of the third part not connected to the handle 1 along a preset path to one side of the needle body 2 and then joined to one end of the first part. The preset path is determined based on the shape and volume of the obstruction, so that the avoidance part 3 formed by the needle body 2 extending along the preset path can bypass the obstruction during puncture, i.e., avoid the obstruction, ensuring that the needle body 2 does not have significant contact with the obstruction or puncture it during its insertion into and removal from the human body. The shape and size of the avoidance part 3 formed by the second part of the needle body 2 bending and extending along the preset path correspond to the preset path. That is, the preset path determines the shape and size of the avoidance part 3.

[0049] For ease of manufacturing, in this embodiment, the shape of the avoidance part 3 is summarized as including at least one of the following forms: arc, rectangle, trapezoid, and irregular shape formed based on the outline of the obstacle.

[0050] In actual use, the target point, the appropriate entry point on the human body, and the movement path of the bone puncture needle in the human body can be confirmed based on the human body scan image. Then, based on the movement path and the human body scan image, the obstacles that the needle body 2 will encounter during the movement and puncture process are determined, including soft tissue, bone tissue, etc. After that, the size and shape of the obstacle are combined to select and determine the bone puncture needle with a matching avoidance part 3. Finally, the bone puncture needle is used to insert into the human body to complete the puncture process.

[0051] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. The scope of protection of this utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this utility model within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this utility model.
