Description

Technical Field

[0001] This utility model relates to the field of medical devices, and more specifically, to a kit for anesthesia puncture. Background Technology

[0002] A puncture needle is a medical device used in minimally invasive surgery to sample and inject tissues from various organs such as the kidneys, liver, lungs, breasts, thyroid glands, prostate, pancreas, testes, uterus, ovaries, and body surface.

[0003] When existing puncture needles are used inside the human body, they need to move inside the body. During this movement, the tip of the puncture needle needs to drive the catheter at the back of the body. If the tip of the puncture needle is too sharp, it can easily cause damage to the inside of the body. If the tip of the puncture needle is too blunt, it is more difficult for the puncture needle to move inside the body.

[0004] Therefore, a kit for anesthesia puncture is proposed to address the above problems. Utility Model Content

[0012] The technical effects and advantages of this utility model are as follows:

[0013] Compared with the prior art, the present invention has a circular arc-shaped tip of the puncture needle, which will not cause damage to the human body when it moves inside the body. Furthermore, the cone-shaped block and the flow channel on its surface at the tip of the puncture needle facilitate the movement of the puncture needle inside the human body. At the same time, the cross-section of the top of the cone-shaped block is arc-shaped, which prevents the cone-shaped block from causing damage to the human body during movement.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] As attached Figure 1 , Figure 2 and Figure 3The kit shown includes a puncture needle 1, a fluid reservoir 2 at one end of the puncture needle 1, a delivery channel 7 in the middle of the puncture needle 1, an arc-shaped front end of the puncture needle 1, and four sets of cones 8 at the front end of the puncture needle 1. Multiple flow channels are opened on the surface of the cones 8, and the cross-section of the top of the cones 8 is arc-shaped. A handle 5 is provided on the surface of the puncture needle 1, and a fixing mechanism 6 is provided at one end of the handle 5. Both the fixing mechanism 6 and the handle 5 are fitted onto the surface of the puncture needle 1.

[0022] Specifically: Since the tip of the puncture needle 1 is arc-shaped, it will not cause damage to the human body when it moves inside the body. The cone 8 set at the tip of the puncture needle 1 and the flow channel opened on its surface are used to allow the puncture needle 1 to move inside the human body. At the same time, the cross-section of the top of the cone 8 is arc-shaped to avoid the cone 8 causing damage to the human body when it moves inside the body.

[0023] Example 2

[0024] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below, with reference to the specific working method described in detail:

[0025] like Figure 4 As shown, in a preferred embodiment, the fixing mechanism 6 includes a housing 61 sleeved on the surface of the puncture needle 1. A through hole is provided in the middle part of the housing 61. One end of the through hole is fixedly disposed on a hollow fixing plate, and a hollow rotating plate 62 is movably disposed on the other end of the through hole. Multiple sets of flexible tubes 63 are disposed between the hollow fixing plate and the hollow rotating plate 62. Furthermore, by rotating the hollow rotating plate 62, the flexible tubes 63 are driven to rotate. Since the hollow rotating plate 62 moves while the hollow fixing plate does not move, the multiple sets of flexible tubes 63 converge towards the middle part, thereby using the flexible tubes 63 to fit against the puncture needle 1, thereby fixing the puncture needle 1 so as to push the puncture needle 1 to move inside the human body.

[0026] like Figure 4 As shown, in a preferred embodiment, a slide rail is provided on the surface of the housing 61, and a lever 64 is movably arranged inside the slide rail. The lever 64 is connected to the hollow rotating plate 62. Furthermore, by rotating the lever 64, the hollow rotating plate 62 is driven to rotate.

[0027] like Figure 4 As shown, in a preferred embodiment, the handle 5 has a through hole in the middle part, and the handle 5, the hollow fixing plate and the hollow rotating plate 62 are sleeved on the outer surface of the puncture needle 1. Furthermore, by utilizing the through hole in the middle part of the handle 5, the hollow fixing plate and the hollow rotating plate 62, the handle 5 and the fixing mechanism 6 are sleeved on the outer surface of the puncture needle 1.

[0028] like Figure 1As shown, in a preferred embodiment, a connector 3 is provided between the puncture needle 1 and the liquid storage bag 2.

[0029] like Figure 1 As shown, in a preferred embodiment, an adjuster 4 is provided between the puncture needle 1 and the reservoir bag 2, and the adjuster 4 is located below the connector 3.

[0030] The working process of this utility model is as follows:

[0031] When this utility model is used, since the front end of the puncture needle 1 is arc-shaped, it will not cause damage to the human body when it moves inside the body. Furthermore, the cone block 8 provided at the front end of the puncture needle 1 and the flow channel opened on its surface enable the puncture needle 1 to move inside the human body. At the same time, the cross-section of the top of the cone block 8 is arc-shaped, which prevents the cone block 8 from causing damage to the human body during its movement.

[0032] When this utility model is used, the hollow rotating plate 62 is rotated to drive the hose 63 to rotate. Since the hollow rotating plate 62 moves while the hollow fixing plate does not move, multiple sets of hoses 63 are gathered towards the middle part, so that the hoses 63 fit with the puncture needle 1 to fix the puncture needle 1, so as to push the puncture needle 1 to move inside the human body.
