Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a connection mechanism for long medical tube devices. Background Technology

[0002] In minimally invasive orthopedic surgery or other types of medical surgery, a connection technology between a certain filament and a hollow ultrathin-walled tube is required to fix multiple bundles of microfilaments inside the hollow ultrathin-walled tube and finally enter the simulated cavity. Currently, long tube-type device structures are often used for assistance. However, special connection structures are required inside long tube devices to realize the transport and movement of tissues, thereby completing the fixation or repair of different tissues.

[0003] In the prior art, patent CN203829029U discloses a medical bone filler. It includes a push rod, a sleeve, and a clamping head. The push rod has a sliding retainer in the middle, and the sleeve has recessed sliding tracks on both sides, allowing the push rod to slide up and down along these tracks. The lower end of the first handle of the push rod is connected to a helical interface, and the second handle of the sleeve has a helical groove inside. After the push rod slides into the sleeve a certain length, it can be helically advanced.

[0004] The above structure uses a spiral connection to transport tissues. However, the spiral design results in a smaller tube diameter, less tissue being transported, and more complicated disassembly, which can affect the filling effect. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a connecting mechanism for medical long tube devices to solve the problems that the spiral setting leads to a smaller diameter of the cannula, less tissue delivery, and complicated disassembly, which can easily affect the filling effect.

[0006] Based on the above objectives, this utility model provides a medical long tube device connection mechanism for engaging an inner shell of multiple microfilaments, wherein an outer shell is engaged inside the inner shell, and the inner shell and the outer shell limit the movement of the multiple microfilaments.

[0007] A connecting mechanism is provided on one side of the outer shell, which is used to deliver tissue into multiple bundles of microfilaments;

[0008] The connecting mechanism includes a filling channel tube that is snapped into the inner wall of the inner shell. One end of the filling channel tube is provided with a limiting hook that snaps into the inner wall of the outer shell, and a separation tube is sleeved on the outside of the filling channel tube. The separation tube is in contact with the outer shell.

[0009] Preferably, both the outer shell and the inner shell are hollow annular, and the interior of the outer shell has a concave structure.

[0010] Preferably, the length of the separating tube is less than the length of the filling channel tube, and the filling channel tube and the separating tube are made of the same material.

[0011] Preferably, the inner diameter of the separation tube matches the outer diameter of the filling channel tube.

[0012] Preferably, at least two sets of the card blocks are provided, and the card blocks are evenly distributed on the outer shell.

[0013] Preferably, at least two sets of the limiting hooks are provided, and the included angle of the limiting hooks is an obtuse angle.

[0014] The beneficial effects of this utility model are:

[0015] When the multi-filament bundles are installed with the connecting mechanism and inserted into the simulated cavity, they are forced into a cylindrical shape and enter the cavity. The bundles then return to a spherical shape and fit into the cavity. Tissue is then introduced into the multi-filament bundles through the filling channel tube until the bundles are completely filled. The separation tube is then fixed, and the filling channel tube is pulled out forcefully. The multi-filament bundles are then separated from the connecting mechanism. The entire assembly is easy to install and disassemble, greatly ensuring the tissue filling speed and inner diameter, and significantly reducing the degree of damage. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0022] like Figure 1 , Figure 2 , Figure 3As shown, a medical long tube device connection mechanism includes multiple bundles of microfilaments for implantation in bone joints. The multiple bundles of microfilaments include multiple sets of round wires 6, which are combined into a spherical shape. The ends of the multiple sets of round wires 6 are snapped with an inner shell 3, and an outer shell 2 is snapped into the inside of the inner shell 3. The inner shell 3 and the outer shell 2 limit the position of the round wires 6.

[0023] A connecting mechanism 9 is provided on one side of the multi-bundle microfilaments. The connecting mechanism 9 is used to transport tissue into the multi-bundle microfilaments.

[0024] The connecting mechanism 9 includes a filling channel tube 5 that is snapped into the inner wall of the inner shell 3. One end of the filling channel tube 5 is provided with a limiting hook 8 that snaps into the inner wall of the outer shell 2. A separation tube 4 is sleeved on the outside of the filling channel tube 5, and the separation tube 4 is in contact with the outer shell 2.

[0025] In this embodiment, the filling channel tube 5 in the connecting mechanism 9 is first inserted into the inner shell 3 of the multiple microfilaments. The filling channel tube 5 is then inserted into the inner shell 3 by the limiting hook 8 at one end and is snapped into one end of the inner shell 3. Then, the separating tube 4 is sleeved on the outside of the filling channel tube 5 and contacts the outer shell 2. The overall installation is then completed.

[0026] When inserted into the simulated cavity, multiple microfilaments are forced into the cavity and then return to a spherical shape, fitting the inner cavity. Tissue is then introduced into the microfilaments through the filling channel tube 5 until the microfilaments are completely filled. The separation tube 4 is then fixed, and the filling channel tube 5 is pulled out forcefully. The microfilaments are then separated from the connecting mechanism 9, allowing for easy installation and disassembly. This greatly ensures the filling speed and inner diameter of the tissue, significantly reducing the degree of damage.

[0027] As one implementation method, such as Figure 1 and Figure 3 As shown, both the outer shell 2 and the inner shell 3 are hollow rings, and the interior of the outer shell 2 has a concave structure.

[0028] In this embodiment, multiple sets of round wires 6 are snapped together by the corresponding locking block 7 on the outer shell 2 and the inner shell 3, so that the multiple bundles of microwires remain spherical under no force.

[0029] As one implementation method, such as Figure 1 , Figure 2 As shown, the length of the separation tube 4 is less than the length of the filling channel tube 5, and the filling channel tube 5 and the separation tube 4 are made of the same material.

[0030] The inner diameter of the separation tube 4 matches the outer diameter of the filling channel tube 5.

[0031] In this embodiment, the filling channel tube 5 is used to avoid scratching the ultra-thin wall tube or other tissues at the edge. After filling is completed, the separation tube 4 is shorter than the length of the filling channel tube 5, which makes it easier to fix the separation tube 4 and pull out the filling channel tube 5 by force.

[0032] As one implementation method, such as Figure 3 As shown, there are at least two sets of card blocks 7, and the card blocks 7 are evenly distributed on the outer shell 2.

[0033] In this embodiment, the multiple microfilaments are then connected to the connecting mechanism 9 to improve the fit between the multiple microfilaments as a whole and the bone joint.

[0034] As one implementation method, such as Figure 3 As shown, at least two sets of limit hooks 8 are provided, and the included angle of the limit hooks 8 is an obtuse angle.

[0035] In this embodiment, multiple sets of limiting hooks 8 at one end of the filling channel tube 5 are inserted into the inner shell 3 under stress until they penetrate through and then the limiting hooks 8 are engaged with one end of the inner shell 3, so that the connection strength between the filling channel tube 5 and the multiple bundles of microfilaments is guaranteed and it is easy to disassemble.

[0036] Working principle: When filling the simulated cavity, first install the multiple bundles of microfilaments with the outer shell 2 and the inner shell 3. Insert the filling channel tube 5 in the connecting mechanism 9 into the inner shell 3. The limiting hook 8 at one end of the filling channel tube 5 is inserted into the inner shell 3 under force until it penetrates through and the limiting hook 8 is engaged with one end of the inner shell 3. Then, the separation tube 4 is sleeved on the outside of the filling channel tube 5 and abuts against the outer shell 2. The overall installation is completed.

[0037] During operation, the connecting mechanism 9 enters the ultra-thin-walled tube, first aligning the multiple microfilaments with the opening of the simulated cavity. When inserted into the cavity, the multiple microfilaments are forced into a cylindrical shape, thus entering the simulated cavity. After entering the simulated cavity, the multiple microfilaments finally return to a spherical shape, fitting against the inner cavity of the simulated cavity. Then, the tissue is introduced into the interior of the multiple microfilaments through the filling channel tube 5 until the interior of the multiple microfilaments is filled. The filling channel tube 5 is used to avoid scratching the ultra-thin-walled tube or other tissues at the edges. After filling is completed, the separating tube 4 is fixed, and the filling channel tube 5 is pulled out forcefully. The limiting hook 8 separates from the inner shell 3, and the multiple microfilaments are separated from the connecting mechanism 9 as a whole. The whole assembly is easy to install and disassemble, greatly ensuring the filling speed and inner diameter of the tissue, and significantly reducing the degree of damage.
