[0002] A disposable puncture is a medical device that is usually used to establish a channel during surgery or other medical operations for infusion, blood transfusion, drainage, sampling and other operations. It consists of a puncture needle and a handle. The puncture needle is usually made of stainless steel or plastic, and the handle is usually made of plastic or metal. The handle is the operator's force device, and the operator controls the puncture depth and angle through the handle. However, the comfortable angle for each user to hold the puncture handle will be different. Because everyone's hand shape, hand strength and usage habits are different. In order to improve the user's comfort and operating efficiency, the design of some puncture handles will take into account ergonomic principles, such as the shape of the handle, to meet the needs of different users. However, the handle shape of a traditional puncture is usually one type, which means that when a puncture with a handle of a different shape is needed, the puncture with a handle of a different shape needs to be replaced, which will waste resources and increase medical costs. Utility Model Content

[0024] Example

[0025] like Figure 1-4 As shown, the force-carrying structure of the disposable puncture device proposed by the utility model includes a puncture device body 1 and a spherical handle 2 arranged on the top of the puncture device body 1, and also includes: a vertical grip handle 3 and a horizontal grip handle 4 movably mounted on the spherical handle 2 for allowing the operator to use handles of various shapes through a disposable puncture device, and a plurality of finger fitting grooves 5 arranged linearly and closely fitting with the fingers are provided on the vertical grip handle 3 and the horizontal grip handle 4. The function of the finger fitting grooves 5 is to make the operator hold the vertical grip handle 3 and the horizontal grip handle 4 more firmly, thereby operating the puncture device body 1 more accurately; a button mechanism is arranged on the horizontal grip handle 4 for quickly separating the spherical handle 2, the vertical grip handle 3 and the horizontal grip handle 4 by pressing.

[0026] Furthermore, the button mechanism includes a mounting groove 41 provided on the horizontal grip 4, a button 42 is slidably connected inside the mounting groove 41, a push spring 43 is provided inside the mounting groove 41 for pushing the button 42 to return to its original position, and the push spring 43 is used to push the button 42 to return to its original position for repeated operation without applying pressure to the push button 42. A hemispherical slot 341 is provided on both the horizontal grip 4 and the vertical grip 3, and the hemispherical slot 341 on the horizontal grip 4 is the same size as the hemispherical slot 341 on the vertical grip 3. A main telescopic rod 44 is provided inside the installation slot 41, one end of which movably passes through the horizontal grip 4, and the other end of the main telescopic rod 44 is fixedly connected to the button 42. A pair of card slots 342 are provided inside the hemispherical slot 341. One end of the ball handle 2 and the vertical grip 3 are provided with a hemispherical protrusion 231 for being inserted into the hemispherical slots 341 on the vertical grip 3 and the horizontal grip 4. The hemispherical protrusion 231 on the ball handle 2 and the hemispherical protrusion 231 on the vertical grip 3 are the same in shape and size. A card block mechanism for quickly inserting into the corresponding hemispherical slot 341 is provided on the hemispherical protrusion 231.

[0027] The push spring 43 is movably sleeved with the main telescopic rod 44 , one end of the push spring 43 is fixedly connected to the inner bottom wall of the installation groove 41 , and the other end of the push spring 43 is fixedly connected to the button 42 .

[0028] Secondly, the block mechanism includes a telescopic through slot 237 provided in the ball handle 2 and the vertical grip handle 3. The telescopic through slot 237 in the ball handle 2 is shorter than the telescopic through slot 237 in the vertical grip handle 3, but the diameter is the same. A secondary telescopic rod 232 is slidably connected inside the telescopic through slot 237. The secondary telescopic rod 232 in the ball handle 2 is shorter than the secondary telescopic rod 232 in the vertical grip handle 3, but the thickness is the same. A pair of telescopic grooves 235 corresponding to the secondary telescopic rod 232 are provided inside the hemispherical protrusions 231. A sliding block 233 for being inserted into the corresponding slot 342 is provided inside the telescopic groove 235. One end of the sliding block 233 inserted into the slot 342 is provided with a spherical protrusion for automatically retracting into the telescopic groove 235 after being pressed by the hemispherical slot 341. The secondary telescopic rod 232 and the sliding block 233 are rotatably connected by a rotating rod 234. One end of the secondary telescopic rod 232 in the vertical grip 3 is used to be pressed by one end of the main telescopic rod 44.

[0029] Furthermore, the block mechanism also includes a return spring 236 disposed in the telescopic through slot 237 for pulling the secondary telescopic rod 232 to return to its original position. The function of the return spring 236 is to enable the secondary telescopic rod 232 to quickly return to its original position for operation. One end of the return spring 236 is fixedly connected to the inner wall of the telescopic through slot 237, and the other end of the return spring 236 is fixedly connected to the secondary telescopic rod 232.

[0030] In this embodiment, when the force-carrying structure of the disposable puncture device is required, such as Figure 1 As shown, it is only necessary to press the button 42 inside the installation slot 41, and the button 42 pushes the main telescopic rod 44 against one end of the secondary telescopic rod 232 in the vertical grip 3, and the other end of the secondary telescopic rod 232 in the vertical grip 3 against one end of the secondary telescopic rod 232 in the ball handle 2. Figure 3 and Figure 4As shown, at this time, the secondary telescopic rods 232 in the ball handle 2 and the vertical handle 3 drive one end of the pair of rotating rods 234 to move, and the other end of the rotating rod 234 pulls the sliding block 233 out of the corresponding slot 342, so that the ball handle 2, the vertical handle 3 and the horizontal handle 4 can be quickly disassembled. When the ball handle 2 is needed, the vertical handle 3 and the horizontal handle 4 can be installed without installing; when the vertical handle 3 is needed, only the end of the ball handle 2 with the hemispherical protrusion 231 needs to be inserted into the slot 342 on the vertical handle 3. At this time, the pair of sliding blocks 233 on the ball handle 2 are resisted by the hemispherical slot 341 on the vertical handle 3, and will retract into the telescopic slot 235. Later, through the elastic pulling force of the return spring 236, the secondary telescopic rod 232 drives the rotating rod 234 and the sliding block 233 to return to their original positions, and the vertical handle 3 can be quickly installed on the ball handle 2. When the horizontal grip handle 4 is needed, the horizontal grip handle 4 can be installed on the hemispherical protrusion 231 on the spherical handle 2 or the vertical grip handle 3 according to the length required by the operator to operate the trocar body 1, which is simple and easy to operate.
