Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary appliances, in particular to an anti-detachment guide wire. Background Technique

[0002] Organ fistulation surgery is a commonly used surgery in clinical practice, such as pyelostomy, cystostomy, hydrocephalus fistulation, gastrostomy, etc. It is to directly connect the organ cavity or infection focus to the outside through a new channel, so as to drain, wash, or perform various diagnostic and treatment operations through this channel. The guide wire in the fistulation surgery is a very important link, which plays a role in guiding various instruments. In order to facilitate the penetration of the guide wire, the designed guide wire must be slender and smooth; however, such a structure leads to the easy slipping out of the renal pelvis during the process of guiding other instruments, and due to the slenderness of the guide wire, such slippage is very difficult to detect. Once the guide wire is not sent back to the renal pelvis in time;

[0003] Therefore, the utility model patent with the publication number of CN108175924A discloses an anti-detachment and anti-injury guide wire; it includes a body with a slender tubular shape and an inflatable cavity inside, and an airbag arranged at the front part of the body and communicated with the inflatable cavity. The anti-detachment and anti-injury guide wire provided by the present invention can have its head clamped inside the organ, avoiding the head from slipping out of the target organ or entering too deeply outside the organ or even other surrounding organs and blood vessels, thus avoiding the occurrence of serious complications;

[0004] However, in use, we found that it uses the characteristic of the airbag to inflate and expand for positioning. However, in the above operation, when inflating, the accuracy of inflation is difficult to guarantee, and after inflation is completed, the inflation part cannot be locked. If accidentally touched, it is easy to cause the situation of gas backflow and airbag contraction. Content of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to propose an anti-detachment guide wire. When the guide wire is in use, by using the scale bar, the situation of too little or too much inflation can be avoided. In addition, a locking structure is also provided to avoid the situation of accidental touch after inflation is completed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] An anti - shedding guide wire includes a sleeve, a guide wire is arranged inside the sleeve, the inside of the guide wire is hollow, one end of the guide wire is communicated with an airbag, the other end of the guide wire is connected with a connecting column, a columnar cavity is arranged inside the connecting column, and the guide wire is communicated with the columnar cavity through a connecting channel; an adjusting mechanism, the adjusting mechanism includes a piston plate slidably connected inside the columnar cavity, the upper end of the piston plate is fixedly connected with a threaded sleeve, a threaded rod is threadedly connected inside the threaded sleeve, the upper end of the threaded rod penetrates through the inner top of the columnar cavity and is rotatably connected with the inner top of the columnar cavity.

Detailed implementation manner

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0027] Embodiment 1

[0028] Referring to Figures 1-3 , a non-detachable guide wire includes a sleeve 1. A guide wire 2 is arranged inside the sleeve 1. The inside of the guide wire 2 is hollow. One end of the guide wire 2 is communicated with an airbag 4. The other end of the guide wire 2 is connected with a connecting column 3. A columnar cavity is arranged inside the connecting column 3. The guide wire 2 and the columnar cavity are communicated through a connecting channel 5;

[0029] Among them, an adjusting mechanism is further included. The adjusting mechanism includes a piston plate 6 slidably connected inside the columnar cavity. The upper end of the piston plate 6 is fixedly connected with a threaded sleeve 8. A threaded rod 9 is threadedly connected inside the threaded sleeve 8. The upper end of the threaded rod 9 penetrates through the inner top of the columnar cavity and is rotatably connected with the inner top of the columnar cavity. The upper end of the threaded rod 9 is fixedly connected with a twisting block 10. The upper end of the piston plate 6 is fixedly connected with a plurality of guide rods 7. A plurality of through holes are opened in the inner top of the columnar cavity. A plurality of guide rods 7 all penetrate through the corresponding through holes and are slidably connected with the through holes. The number of the plurality of guide rods 7 is specifically four. The guide rods 7 are made of stainless steel.

[0030] In use, the staff rotates the twisting block 10, which can drive the threaded rod 9 to rotate, thereby driving the threaded sleeve 8 to move downward. The downward movement of the threaded sleeve 8 will drive the piston plate 6 to move downward, and then press the gas in the bottom space of the columnar cavity into the guide wire 2, and finally transfer it to the airbag 4, causing the airbag 4 to expand and realizing the anti-detachment function. Subsequently, if it is necessary to contract the airbag 4, only rotate the twisting block 10 in the reverse direction.

[0031] Embodiment 2

[0032] Referring to Figures 4-5 , the difference between this embodiment and Embodiment 1 is that a sliding groove 12 is opened on the right side of one of the through ports. A slider 13 that can slide left and right is arranged in the sliding groove 12. A plug rod 14 is fixedly connected to the left side of the slider 13. The right side of the slider 13 is elastically connected to the corresponding inner wall of the sliding groove 12 through a spring 16. A connection hole 11 is horizontally penetrated through one of the guide rods 7. The connection hole 11 cooperates with the plug rod 14. A pull rod 15 is fixedly connected to the right side of the slider 13, and the other end of the pull rod 15 extends to the outside.

[0033] Before the piston plate 6 moves downward, pull the pull rod 15. The pull rod 15 drives the slider 13 to move rightward through the slider 13. When the piston plate 6 moves downward to the required position, release the pull rod 15. Under the elastic action of the spring 16, the slider 13 drives the plug rod 14 to insert into the connection hole 11 to achieve locking and avoid the occurrence of subsequent accidental touch.
