Description

Technical Field

[0001] This utility model relates to the field of bronchoscope technology, specifically to a bronchoscope transmission wire fixing device. Background Technology

[0002] A bronchoscopy is a medical device used to examine and treat the respiratory tract using endoscopic techniques. It consists of a flexible tube, a light source, a camera, and a handle, and can be inserted deep into the bronchi to provide doctors with clear internal images.

[0003] During use, the transmission steel wire in the bronchoscope plays a role in controlling the bending and turning of the endoscope, and its stability directly affects the examination and treatment effect.

[0004] However, traditional fixation methods have problems such as the steel wires being easy to loosen and the fixation being unreliable, resulting in inconvenience in the operation of the bronchoscope.

[0005] Based on this, the present invention designs a transmission wire fixing device for a bronchoscope to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a drive wire fixing device for a bronchoscope to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: It includes an upper cover, a lower cover, a capillary steel tube, and a transmission wire. The upper cover is inserted into the lower cover, and the transmission wire is coaxially fixed to the capillary steel tube. A connecting rod is rotatably mounted on the lower cover. A push rod is fixedly mounted on one end of the connecting rod away from the lower cover, and a turntable is fixedly mounted on the other end of the connecting rod away from the push rod. A slot is formed along the circumference of the turntable, and a fixing groove is formed on the side of the turntable away from the push rod. A connecting groove is provided between the slot and the fixing groove, and a clamping platform is fixedly mounted on the fixing groove. A support seat is provided on the upper cover, and an O-ring is placed on the support seat. The O-ring and the connecting rod are arranged coaxially, and the clamping platform abuts against the O-ring. Two capillary steel tubes and two transmission wires are provided respectively. The capillary steel tube is placed in the fixing groove, and the transmission wire is placed sequentially in the fixing groove, the connecting groove, and the slot.

[0008] By adopting the above technical solution, during bronchoscope testing, rotating the push rod causes the turntable to rotate around the connecting rod, which in turn causes the capillary steel tube in the fixed groove to shift, thereby causing the two transmission wires to rotate the serpentine wire. At the same time, when adjusting the transmission wire, it is only necessary to adjust the position of the capillary steel tube in the fixed groove, so that the distance between the connection point between the capillary steel tube and the transmission wire and the connecting groove changes, which can be easily adjusted. At the same time, the fixed groove can also effectively fix the transmission steel wire.

[0009] Preferably, a semi-circular arc-shaped limiting plate is fixedly provided on the turntable, the limiting plate is fixedly provided on the outer side of the circumference of the slot, and the connecting groove is located at the center of the arc of the semi-circular arc-shaped limiting plate.

[0010] By adopting the above technical solution, a semi-circular limiting plate covers the outside of the slot, so that when the transmission wire rotates and drives the snake bone to move, it avoids the situation where the swing push rod cannot turn the snake bone after the transmission wire disengages from the slot.

[0011] Preferably, the turntable includes a turntable and a cover plate, the fixing groove and the slot are formed on the turntable, and the limiting plate is fixedly arranged on the outer side of the circumference of the cover plate; a plug-in block is fixedly arranged on the turntable, and a plug-in hole is formed on the cover plate, and the plug-in block is plugged into the plug-in hole, and multiple sets of plug-in blocks and plug-in holes are provided.

[0012] By adopting the above technical solution, the split turntable design allows the transmission wire to be better confined within the limiting plate during winding.

[0013] Preferably, a fixing buckle is fixedly provided on the lower cover, and the fixing buckle has a guide groove, and there are two guide grooves.

[0014] By adopting the above technical solution, the guide groove is designed so that when the transmission wire is installed on the snake bone, the direction of the transmission wire guided from the turntable is tangent to the turntable, which avoids the transmission wire from breaking due to excessive deflection angle and can better protect the transmission wire.

[0015] In summary, this application has the following beneficial technical effects: During bronchoscope testing, rotating the push rod causes the turntable to rotate around the connecting rod, which in turn causes the capillary steel tube in the fixed groove to shift, thereby causing the two transmission wires to rotate the serpentine wire. Simultaneously, when adjusting the transmission wires, only the position of the capillary steel tube in the fixed groove needs to be adjusted, changing the distance between the connection point between the capillary steel tube and the transmission wire relative to the connecting groove, thus facilitating adjustment. Furthermore, the fixed groove can effectively fix the transmission wires, providing advantages in structural and motion stability for the bronchoscope transmission device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] The following is in conjunction with the appendix Figure 1 —6 provides further detailed description of this application.

[0027] A bronchoscope transmission wire fixing device includes an upper cover 1, a lower cover 2, a capillary steel tube 3, a transmission wire 4, and a snake bone 5. The upper cover 1 is inserted into the lower cover 2, and the transmission wire 4 is coaxially fixed on the capillary steel tube 3. A connecting tube 6 is fixedly provided between the snake bone 5 and the upper cover 1 and the lower cover 2.

[0028] A connecting rod 7 is rotatably mounted on the lower cover 2. A push rod 8 is fixedly mounted on the end of the connecting rod 7 away from the lower cover 2. A turntable 9 is fixedly mounted on the end of the connecting rod 7 away from the push rod 8. A fixing buckle 10 is fixedly mounted on the lower cover 2. A guide groove 11 is opened on the fixing buckle 10. There are two guide grooves 11.

[0029] The turntable 9 includes a turntable 12 and a cover plate 13. A plug-in block 14 is fixedly installed on the turntable 12, and a plug-in hole 15 is opened on the cover plate 13. The plug-in block 14 is plugged into the plug-in hole 15. There are multiple sets of plug-in blocks 14 and plug-in holes 15.

[0030] A slot 16 is provided on the outer side of the turntable 12 along the circumference. A fixing groove 17 is provided on the side of the turntable 12 away from the slot 16. A connecting groove 18 is provided between the slot 16 and the fixing groove 17. A clamping platform 19 is fixedly provided on the fixing groove 17.

[0031] A semi-circular limiting plate 20 is fixedly installed on the cover plate 13. The limiting plate 20 is fixedly installed on the outer side of the circumference of the cover plate 13, and the connecting groove 18 is located on the center of the arc of the semi-circular limiting plate 20.

[0032] The upper cover 1 has a support seat 21, on which an O-ring 22 is placed. The O-ring 22 and the connecting rod 7 are arranged coaxially, and the pressing platform 19 abuts against the O-ring 22.

[0033] Two capillary steel tubes 3 and two transmission wires 4 are provided. The capillary steel tube 3 is placed in the fixed groove 17, and the transmission wire 4 is placed in the fixed groove 17, the connecting groove 18 and the slot 16 in sequence. The end of the transmission wire 4 away from the capillary steel tube 3 passes through the connecting pipe 6 and is fixedly set on the snake bone 5 away from the connecting pipe 6.

[0034] The implementation principle of this embodiment is as follows: When adjusting the hyoid bone 5, the upper cover 1 is removed from the lower cover 2, and the shape of the capillary tube 3 can be adjusted in the fixing groove 17. After the capillary tube 3 is bent and deformed, it is locked in different positions in the fixing groove 17. The position of the connection point between the capillary tube 3 and the transmission wire 4 changes relative to the connecting groove 18, so that the distance between the transmission wire 4 and the hyoid bone 5 changes, thus completing the adjustment of the hyoid bone 5. When using the bronchoscope, the push rod 8 is turned so that the push rod 8 drives the connecting rod 7 to rotate around the lower cover 2. After the turntable 9 rotates, the position of the two transmission wires 4 relative to the hyoid bone changes, thus achieving the purpose of adjusting the angle of the hyoid bone 5.

[0035] During bronchoscope testing, rotating the push rod 8 causes the turntable 9 to rotate around the connecting rod 7, which in turn causes the capillary tube 3 in the fixing groove 17 to shift, thereby causing the two transmission wires 4 to drive the snake bone 5 to change direction. At the same time, when adjusting the transmission wires 4, it is only necessary to adjust the position of the capillary tube 3 in the fixing groove 17, so that the distance between the connection point between the capillary tube 3 and the transmission wire 4 and the connecting groove 18 changes, which can be easily adjusted. At the same time, the fixing groove 17 can also effectively fix the transmission wires, which has the advantages of structural stability and motion stability of the bronchoscope transmission device.
