Description
Technical Field
[0001] The utility model relates to the technical field of medical device processing equipment, in particular to a component assembly tooling suitable for a lung tumor positioning needle with an anchor hook fixing structure. Background Art
[0002] In recent years, the number of patients with lung nodules has been increasing. The early diagnosis of lung nodules is relatively difficult, lacking specificity clinically, with diverse morphological manifestations on imaging, and it is not easy to determine benign or malignant, often resulting in misdiagnosis and delaying treatment. With the improvement of minimally invasive techniques, thoracoscopic small incision surgery is usually used to remove lung nodules. During the operation, finding small lung nodules under the thoracoscope is the key to the success of the surgery. Small lung nodules are difficult to palpate and guide resection after the lung tissue is compressed and consolidated. Resecting the lung lobe or lung segment causes too much trauma. Therefore, preoperative puncture positioning is very important. In the prior art, the CT-guided fine needle lung puncture positioning technique is widely used in the surgical resection of lung nodules.
[0003] In this regard, for example, the lung tumor positioning needle with an anchor hook fixing structure disclosed in the patent publication No. CN217430123U includes a puncture needle and an anchor hook adapted to be received in the puncture needle. For this anchor hook, it is received in the puncture needle before use, and the anchor hook itself has a certain elasticity to facilitate its recovery of the hook shape to meet the use requirements when it is detached from the puncture needle during use. For an anchor hook with a certain elasticity, it is relatively difficult to install it into a puncture needle with a relatively limited inner diameter. Therefore, in the actual production and assembly process of this lung tumor positioning needle, how to efficiently and accurately install the anchor hook into the puncture needle is a technical problem to be overcome.

Detailed implementation mode
[0038] In order to make the content of the present utility model easier to be clearly understood, the present utility model will be further described in detail below according to specific embodiments in conjunction with the drawings.
[0039] Please refer to Figures 1 to 5 As shown, this embodiment provides a component assembly tool for a lung tumor positioning needle with an anchor hook fixing structure, including: a support base 1 and an anchor hook positioning line 22 clamp and a puncture needle positioning and moving assembly provided on the support base 1. The support base 1 has a workbench surface 11.
[0040] Next, specifically, first is the anchor hook positioning line 22 clamp, which is provided on the workbench surface 11 for clamping and fixing the anchor hook positioning line 22 connected to the anchor hook 21.
[0041] In order to meet the usage requirements of the anchor hook positioning line 22 clamp to clamp and release the anchor hook positioning line 22, an optional situation of the anchor hook positioning line 22 clamp is given by way of example in combination with the drawings:
[0042] Generally, the anchor hook positioning line 22 clamp includes a base, a fixed clamping block 32 fixed on the base, and a movable clamping block 33 slidably connected to the base; a gap for clamping the anchor hook positioning line 22 is adapted to be formed between the fixed clamping block 32 and the movable clamping block 33. In this structure, by adjusting the position of the movable clamping block 33 on the base, the size of the gap formed between the movable clamping block 33 and the fixed clamping block 32 is adjusted, so as to facilitate clamping or releasing the anchor hook positioning line 22.
[0043] More specifically, in order to facilitate adjusting the position of the movable clamping block 33 on the base, the following design is made in this embodiment:
[0044] The base includes a base plate 31122 provided at the bottoms of the fixed clamping block 32 and the movable clamping block 33, and a side plate 312 provided at the side of the base plate 31122; the side plate 312 is located on the side of the movable clamping plate facing away from the fixed clamping plate; and a locking rod 34 is also connected to the side plate 312, and one end of the locking rod 34 is adapted to penetrate through the side plate 312 and then push against the movable clamping plate. In this structure, by loosening or tightening the locking rod 34, the pushing force of the locking rod 34 on the movable clamping plate can be adjusted, so as to adjust the size of the gap formed between the movable clamping block 33 and the fixed clamping block 32.
[0045] On the basis of the above structure, in order to limit that the movable clamping plate can only perform translational movement relative to the fixed clamping block 32 on the base, and there will be no movement in other directions, the following design is also made in this embodiment: the fixed clamping block 32 is a T-shaped structure; and a U-shaped positioning groove 331 adapted to be inserted and matched with the fixed clamping block 32 is formed on the movable clamping block 33.
[0046] Next, the puncture needle positioning and moving assembly will be described:
[0047] Generally, it includes a first sliding seat 4 for fixing the needle seat of the puncture needle, a second sliding seat 5 for inserting the needle tip of the puncture needle, and a linkage member provided between the first sliding seat 4 and the second sliding seat 5; both the first sliding seat 4 and the second sliding seat 5 are adapted to move along the same straight-line trajectory on the workbench surface 11. The first sliding seat 4 and the second sliding seat 5 can move synchronously under the action of the linkage member.
[0048] In order to satisfy the sliding fit between the first sliding seat 4 and the second sliding seat 5 and the base, the following design is also made in this embodiment:
[0049] A guide rail 6 adapted to the first sliding seat 4 and the second sliding seat 5 is provided on the workbench surface 11; and the first sliding seat 4 and the second sliding seat 5 are respectively slidably fitted with the guide rail 6 through a slider.
[0050] And considering that in order to facilitate the fixing of the linkage member, the following structure is adopted in this embodiment:
[0051] The widths of the first sliding seat 4 and the second sliding seat 5 in the direction perpendicular to the guide rail 6 are the same; and the linkage member includes a pair of connecting plates respectively connected to a pair of outer side walls of the first sliding seat 4 and the second sliding seat 5 parallel to the guide rail 6.
[0052] Combined with the attached drawings, an optional implementation case is given. Each connecting plate includes a plate-shaped body 7 and a strip-shaped through groove 72 preset on the plate-shaped body 7 and parallel to the guide rail 6; wherein the second sliding seat 5 is connected to the plate-shaped body 7 through a fastener 73, and the first sliding seat 4 is connected to the strip-shaped through groove 72 through a fastener 73.
[0053] Based on the above structure, it should also be noted that, first of all, a limiting cavity 414 for embedding the needle base and a connecting cavity 42 communicating with the limiting cavity 414 are provided in the first sliding seat 4; the opening size of the connecting cavity 42 is smaller than the opening size of the limiting cavity 414 so that a T-shaped limiting step is formed between the connecting cavity 42 and the limiting cavity 414. Under this structure, the needle base can be limited in the above-mentioned limiting cavity 414 and can move synchronously with the movement of the first sliding seat 4. It can be understood that notches communicating with the limiting cavity 414 are respectively formed on the two side end faces of the first sliding seat 4 extending along the guide rail to meet the use requirements for the passing of the anchor hook positioning wire 22 and the needle tube of the puncture needle.
[0054] A guiding member 8 is further provided in the second sliding seat 5. A guiding hole suitable for the anchor hook 21 to pass through is formed in the guiding member 8, and the needle tip is suitable for being inserted into the guiding hole. The guiding member 8 adopts a T-shaped structure; and the guiding hole penetrates through the T-shaped structure. It should be noted that the inner diameter of the guiding hole here is slightly larger than the outer diameter of the columnar connecting portion of the anchor hook 21, so that the anchor hook 21 can be reversibly deformed during the process of entering the guiding hole. The specific reverse here refers to the hook shape opposite to the use state of the anchor hook 21. Through the design of the guiding member 8 here, the deformed anchor hook 21 can be prepared to enter the needle tip, thereby improving the efficiency and accuracy of its entry into the needle tip.
[0055] Based on the above situation, in order to enable the second sliding seat 5 to meet the matching effect for the guiding member 8:
[0056] A T-shaped accommodating groove 51 for embedding the guiding member 8 is provided in the second sliding seat 5; openings communicating with the T-shaped accommodating groove 51 are respectively formed on the two side end faces of the second sliding seat 5 along the direction of the guide rail; and a transition groove 52 is further provided on the second sliding seat 5 between the T-shaped accommodating groove 51 and the opening of the second sliding seat 5 facing the first sliding seat 4. It should be noted here that for the guiding member 8, its transverse portion is located on the side facing the first sliding seat 4.
[0057] In summary, regarding the component assembly tooling of the lung tumor positioning needle applicable to the anchor hook fixing structure of this embodiment, one end of the anchor hook positioning wire 22 is clamped by the anchor hook 21 positioning fixture, and the entire anchor hook positioning wire 22 penetrates through the needle base, needle tube and needle tip of the puncture needle. At this time, the puncture needle is fixed through the cooperation of the first sliding seat 4 and the second sliding seat 5. In this way, when the first sliding seat 4 and the second sliding seat 5 are pulled to drive the puncture needle to move linearly, the anchor hook 21 can be loaded into the needle tip. During this process, the guiding member 8 provided in the second sliding seat 5 is used to pre-deform the anchor hook 21, so that it can enter the needle tip faster, and the accuracy and efficiency of loading the anchor hook 21 into the needle tip of the puncture needle are improved.
[0058] Specifically, during the process of assembling the anchor hook 21 into the needle head, the end of the anchor hook positioning line 22 away from the anchor hook 21 is first passed through the guide member 8, the needle head of the puncture needle, the needle tube and the needle seat in sequence, and the end of the anchor hook positioning line 22 away from the anchor hook 21 is extended to the side of the needle seat away from the needle tube, and the end of the anchor hook positioning line 22 is clamped and fixed by the anchor hook 21 positioning clamp. Then the needle seat is limited and fixed in the first slide 4, and the guide member 8 with the needle inserted at one end is limited and fixed in the second slide 5. At this time, the overall anchor hook 21 and puncture needle are ready and can be assembled. At this point, the first slide 4 and the second slide 5 are moved so that both move toward the side of the anchor hook 21. In this process, since the end of the anchor hook positioning line 22 away from the anchor hook 21 is fixed, the distance between the second slide 5 and the anchor hook 21 gradually decreases. As the second slide 5 continues to move, the anchor hook 21 first enters the guide hole of the guide member 8, so that the anchor hook 21 can be flipped and deformed in the process of entering the guide hole, so that the flipped anchor hook 21 can accurately and quickly enter the needle, thus completing the operation process of assembling the anchor hook 21 into the needle.
