Description

Technical Field

[0001] This utility model relates to the field of urinary catheter processing technology, specifically to an auxiliary positioning mechanism for processing the side hole of a urinary catheter. Background Technology

[0002] A urinary catheter is a medical device, usually made of a flexible tubular material, used to drain urine from the bladder to the outside of the body. The end of the catheter has a side hole for drainage.

[0003] Current technologies, such as the side-hole drilling device for urinary catheter processing disclosed in Chinese Patent Publication No. CN 222450569 U, involve first inserting the end of the urinary catheter into the mounting hole, and then using a cylinder to drive the cutting tool on the sliding seat to move towards the processing mold... However, the above-mentioned side hole processing device has a defect: the catheter is not fixed during the drilling process. On the one hand, the catheter itself is easily deflected by factors such as gravity, and on the other hand, the catheter will also deflect during the process of being squeezed by the drill bit, resulting in inaccurate drilling and uneven side hole positions.

[0004] This case arose from the aforementioned issues. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an auxiliary positioning mechanism for processing the side hole of a urinary catheter, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary positioning mechanism for processing the side hole of a urinary catheter, comprising a base and a mold, a drilling mechanism, and a positioning mechanism disposed on the base. The mold has a plurality of mold holes arranged laterally on its upper side for inserting the urinary catheter. The front side of the mold has a drill hole that communicates with the mold holes. The drilling mechanism corresponds to the drill hole. The rear side of the mold has a positioning hole that allows the positioning mechanism to enter. The positioning mechanism enters the positioning hole to fix the urinary catheter.

[0007] Preferably, there are two sets of positioning holes, which are located on both sides of the corresponding drill hole.

[0008] Preferably, the positioning mechanism includes a vertical plate, several positioning blocks, a linkage plate, a guide rod, an electromagnet, and a magnetic block. The vertical plate is fixed on the base, and the several positioning blocks are all set on the linkage plate and correspond one by one to the positioning holes. The guide rod is horizontally set on the vertical plate, and the linkage plate has a guide hole that is adapted to slide with the guide rod. The electromagnet and the magnetic block are respectively set on the vertical plate and the linkage plate. When the electromagnet is energized, the magnetic pole on the side corresponding to the magnetic block is the same.

[0009] Preferably, the positioning block is U-shaped, and its inner diameter is slightly smaller than the diameter of the catheter.

[0010] Preferably, the drilling mechanism includes a plurality of drill bits, a drive plate, a cylinder, and a guide rail. The drill bits are mounted on the drive plate and correspond one-to-one with the drilling holes. The cylinder is arranged horizontally and its output end is connected to the drive plate. The guide rail is arranged horizontally on the base. The drive plate is provided with a slider that is slidably adapted to the guide rail.

[0011] Preferably, the front side of the mold is provided with an electric heating ring corresponding to each drill hole, and the electric heating ring is sleeved on the outside of the drill bit.

[0012] This utility model provides an auxiliary positioning mechanism for machining the side hole of a urinary catheter. It has the following beneficial effects: 1. The auxiliary positioning mechanism for machining the side hole of the urinary catheter has two sets of positioning mechanisms on both sides of the drill hole. The positioning mechanism can fix the front and back of the urinary catheter during drilling, preventing the urinary catheter from shifting during drilling and preventing the urinary catheter from deforming during drilling, thus ensuring accurate drilling.

[0015] This utility model embodiment provides an auxiliary positioning mechanism for machining the side hole of a urinary catheter, such as... Figure 1-3 As shown, the device includes a base 1 and a mold 2, a drilling mechanism, and a positioning mechanism mounted on the base 1. The mold 2 has several side-arranged holes 3 for inserting a catheter. The arrangement of these holes increases production capacity. A drilled hole 4, communicating with the hole 3, is located on the front side of the mold 2. The drilling mechanism corresponds to the drilled hole 4. A positioning hole 11, accessible to the positioning mechanism, is located on the rear side of the mold 2. The positioning mechanism enters the positioning hole 11 to fix the catheter.

[0016] There are two sets of positioning holes 11, located on both sides of the corresponding drill hole 4. The two sets of positioning holes 11 on both sides of the drill hole 4 can fix the catheter at the front and back during drilling, preventing the catheter from shifting during drilling and preventing deformation of the catheter during drilling, thus ensuring accurate drilling.

[0017] like Figure 2-3 As shown, the positioning mechanism includes a vertical plate 12, several positioning blocks 13, a linkage plate 14, a guide rod 15, an electromagnet 17, and a magnetic block 18. The vertical plate 12 is fixed on the base 1. The positioning blocks 13 are all arranged on the linkage plate 14 and correspond one-to-one with the positioning holes 11. The guide rod 15 is arranged horizontally on the vertical plate 12. The linkage plate 14 has guide holes 16 that are slidably adapted to the guide rod 15. The electromagnet 17 and the magnetic block 18 are respectively arranged on the vertical plate 12 and the linkage plate 14. When the electromagnet 17 is energized, the magnetic poles on the side corresponding to the magnetic block 18 are the same. In order to facilitate the resetting of the positioning blocks 13, a spring is sleeved on the guide rod 15 between the ends of the linkage plate 14 and the guide rod 15. Under normal conditions, the positioning blocks 13 are moved away from the positioning holes 11 by the action of the spring.

[0018] Once the catheter is fully inserted into the die hole 3, the electromagnet 17 is energized, pushing several positioning blocks 13 to move into the positioning hole 11. The positioning blocks 13 hold the catheter in the die hole 3, preventing it from shifting during the drilling process.

[0019] The positioning block 13 is U-shaped, with its inner diameter slightly smaller than the diameter of the catheter. This allows the positioning block 13 to position the catheter while reducing compression on it.

[0020] like Figure 1 As shown, the drilling mechanism includes several drill bits 5, a drive plate 6, a cylinder 7, and a guide rail 8. The drill bits 5 are mounted on the drive plate 6 and correspond one-to-one with the drill holes 4. The cylinder 7 is horizontally positioned, and its output end is connected to the drive plate 6. The guide rail 8 is horizontally positioned on the base 1, and a slider 9 is mounted on the drive plate 6 and slidably adapted to the guide rail 8. The cylinder 7 is used to push the drill bits 5 to move in the direction of the drill holes 4 to drill holes in the catheter.

[0021] An electric heating coil 10 is provided on the front side of the mold 2 corresponding to each drill hole 4, and the electric heating coil 10 is sleeved on the outside of the drill bit 5. The heating coil 10 is used to provide heat to the drill bit 5, so that it can easily complete the drilling operation.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
