Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a lung nodule positioning device. Background Technology

[0002] Currently available lung nodule localization products have several problems in practical use, such as anchor point misalignment or guide point detachment from the anchor point. This is due to insufficient anchoring capacity of the positioning end, poor rigidity of the one-piece structure, and the fact that the guide point is composed of multiple strands of silk inside the body with an overly rough and complex surface. Excessive friction between the multiple strands and the chest wall tissue causes the positioning end to shift when the patient gets up or turns over. The detachment of the guide point from the anchor point occurs under these circumstances. Due to excessive traction and uncontrollable force, the guide silk is pulled out of the anchor point, leaving only the anchor point inside the lung tissue, leading to positioning failure. Furthermore, it is difficult to locate the positioning end buried in the lung tissue during surgery. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a lung nodule localization device.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A lung nodule positioning device is provided, comprising: an anchoring part, a connecting tube sleeved on the proximal end of the anchoring part and fixedly connected to the anchoring part, and a guiding part sleeved on the proximal end of the connecting tube;

[0006] The anchoring part includes: a plurality of anchoring hooks evenly arranged along the circumferential direction of the connecting pipe;

[0007] The connecting tube includes a locking part; the distal end of the guide part is connected to the connecting tube through the locking part.

[0008] Preferably, the locking part includes: a first through hole opened in the middle of the side wall of the connecting pipe, and a first locking pin disposed in the first through hole.

[0009] More preferably, the locking part further includes: a second through hole opened near the side wall of the connecting pipe, and a second locking pin disposed in the second through hole.

[0010] More preferably, the opening direction of the first through hole is perpendicular to the opening direction of the second through hole.

[0011] Preferably, the locking part is a stop piece, which is sleeved inside the connecting tube.

[0012] Preferably, the locking portion is formed by the contraction of the proximal end of the connecting tube.

[0013] More preferably, the locking part includes two locking tubes arranged side by side, and the distal end of the guide part is sleeved inside the locking part.

[0014] The present invention adopts the above technical solution and has the following technical effects compared with the prior art:

[0015] This invention features a locking part that locks the guide part inside the connecting tube, preventing it from easily coming out. The proximal end of the anchoring part is also fitted inside the connecting tube. The two ends of the connecting tube are respectively fixed to the anchoring part and the guide part, which enhances the stability of the positioning device and prevents the anchoring part from separating from the guide part, thus affecting the positioning effect.

[0029] During assembly, the worker folds the far end of the guide part 3 in half and inserts it into the connecting tube 2. The first locking pin 4 passes through the middle of the folded guide part 3 to lock the guide part 3 in the connecting tube 2, so that the guide part 3 will not come out of the connecting tube 2.

[0030] Example 2

[0031] like Figure 2 As shown, this embodiment provides another lung nodule positioning device, including: an anchoring part 1, a connecting tube 2 sleeved on the proximal end of the anchoring part 1 and fixedly connected to the anchoring part 1, and a guide part 3 sleeved on the proximal end of the connecting tube 2;

[0032] The anchoring part 1 includes a plurality of anchoring hooks 11 evenly arranged along the circumferential direction of the connecting pipe 2; the connecting pipe 2 includes a locking part; the distal end of the guiding part 3 is connected to the connecting pipe 2 through the locking part; the locking part includes a first through hole opened in the middle of the side wall of the connecting pipe 2, a second through hole opened in the proximal end of the side wall of the connecting pipe 2, a first locking pin 4 disposed in the first through hole and a second locking pin 5 disposed in the second through hole, wherein the opening direction of the first through hole is perpendicular to the opening direction of the second through hole.

[0033] During assembly, the worker folds the far end of the guide part 3 in half and inserts it into the connecting tube 2. After passing the first locking pin 4 through the middle of the folded guide part 3, the worker twists the guide part 3 again so that the second locking pin 5 can be inserted into the second through hole. At this time, the first locking pin 4 and the second locking pin 5 lock the guide part 3 in multiple ways, so that the guide part 3 will not come out of the connecting tube 2.

[0034] Example 3

[0035] like Figure 3As shown, this embodiment provides another lung nodule positioning device, including: an anchoring part 1, a connecting tube 2 sleeved on the proximal end of the anchoring part 1 and fixedly connected to the anchoring part 1, and a guide part 3 sleeved on the proximal end of the connecting tube 2;

[0041] During assembly, the worker inserts the guide part 3 into the connecting tube 2, and then applies a ring pressure to the proximal end of the connecting tube 2, causing the proximal end of the connecting tube 2 to shrink and wrap around the guide part 3, preventing it from coming out.

[0042] Example 5

[0043] like Figure 5 As shown, this embodiment provides another lung nodule positioning device, including: an anchoring part 1, a connecting tube 2 sleeved on the proximal end of the anchoring part 1 and fixedly connected to the anchoring part 1, and a guide part 3 sleeved on the proximal end of the connecting tube 2;
