The product quality of the bonding between the rotary biopsy needle and the needle holder is particularly important in any medical device or system. The current rotary biopsy needle gluing work is basically to keep the rotary biopsy needle and the needle holder coaxial by human eyes. Due to the shortcomings of low efficiency and low precision of human judgment, the gluing yield is unstable and the efficiency is low.

[0017] The utility model will be described in detail below with reference to the accompanying drawings: Figure 1 As shown, a self-locking structure of a rotary cutting biopsy needle gluing tooling comprises an integrally formed workbench 1, wherein the workbench 1 is composed of a plurality of parallel arranged horizontal positioning blocks 2, which are connected and fixed to each other by vertical connecting blocks 3, and a first groove 6 and a second groove 7 are respectively provided on the positioning blocks, wherein the first groove 6 of the bottommost horizontal positioning block 2 is larger than the remaining second grooves 7 and is used to place a needle seat 4, and the remaining second grooves 7 are used to place a biopsy needle 5, and the biopsy needle 5 and the needle seat 4 are kept vertically and concentrically, and a self-locking device is installed on the upper positioning block to fix the biopsy needle 5 to prevent it from moving during the gluing process.

[0018] There are three lateral positioning blocks 2, which are respectively arranged at the upper, middle and lower positions, one side of which is connected and fixed by a connecting block to form a whole. The middle positioning block is close to the upper positioning block, and a self-locking device is installed between the two positioning blocks. The position between the middle and the lower part is used to place a UV curing lamp (not shown in the figure).

[0019] The upper, middle and lower positioning blocks are provided with an inwardly recessed second groove 7 and a first groove 6 at the lateral position away from one side of the connecting block, wherein the second groove 7 provided on the upper and middle positioning blocks is smaller than the first groove 6 provided on the lower positioning block and is used for placing the biopsy needle, and the first groove 6 of the lower positioning block is used for placing the needle seat 4.

[0020] The inner ends of the first groove 6 and the second groove 7 are both provided with arc-shaped contour walls, so that the biopsy needle 5 and the needle seat 4 can be more closely attached to the wall and fixed.

[0021] The self-locking device is a long strip of locking block 8, one end of which is away from the second groove 7 and is exposed on the outside of the workbench 1, and the other end is longer than the second groove 7 and is provided with an arc profile matching the outer cylindrical surface of the rotary biopsy needle. The locking block 8 is fixed between the upper and middle positioning blocks through a rotating shaft 9, and a spring 10 is installed on the side of the rotating shaft 9 away from the second groove 7. By pressing the end exposed on one side of the workbench 1, the locking block 8 is moved away from the second groove 7 for the placement of the biopsy needle 5. The spring 10 rebounds to make the arc profile of the locking block 8 press the biopsy needle 5 in the second groove 7 and fix it.

[0022] The working process of the utility model is as follows:

[0023] After the utility model is assembled, it is placed in a clean workshop, and the biopsy needle and the needle seat are assembled together, and a proper amount of glue is added to the glue gap; the locking block of the self-locking device is pressed by hand to open the self-locking device, and the biopsy needle and the needle seat are pushed into the arc-shaped wall surface close to the positioning block, and the locking block of the self-locking device is released by hand to lock the biopsy needle and the needle seat under the action of the spring force, and the biopsy needle and the needle seat are relatively close to the arc-shaped wall surface of the positioning block and the relative positions are fixed; the ultraviolet curing lamp is turned on to irradiate and cure the glue, and after the biopsy needle is glued, the locking block of the self-locking device is pressed by hand to open the self-locking device, and the biopsy needle is moved out from the side, and the gluing process is completed; during the whole process, there is no risk of any damage to the needle tip, and the biopsy needle and the needle seat are fixed without manual correction and fixation during the whole process, and the biopsy needle assembly can be removed after the irradiation and curing are completed.

[0024] The working principle of the utility model is as follows:

[0025] In order to fix the relative position of the biopsy needle and the needle seat, we used precision electric spark wire cutting to process the arcuate wall of the positioning block. When the circular outer surfaces of the biopsy needle and the needle seat are in close contact with the arcuate wall, the biopsy needle and the needle seat remain vertical and concentric. In order to keep the biopsy needle and the needle seat in close contact with the arcuate wall, a self-locking device structure is designed to press the rear end of the locking block of the self-locking device. The locking block of the self-locking device rotates through the self-locking device shaft, and the locking block of the self-locking device does not interfere with the biopsy needle freely entering and exiting the positioning block groove. When the locking block of the self-locking device is loosened, the locking block of the self-locking device applies pressure to the arcuate wall of the positioning block under the action of the spring, fixing the relative position of the biopsy needle and the needle seat, and no other external force is needed to assist in keeping the biopsy needle and the needle seat vertical and concentric. This provides fast, accurate and effective gluing positioning assistance for the biopsy needle gluing process.

[0026] The specific embodiments described herein are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by a person of ordinary skill in the art without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
