Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical catheter, in particular to a sheath product detection device for sheath preparation. BACKGROUND

[0002] Interventional therapy is a new medical method gradually rising in recent years, which can extend into organs in the human body through catheter penetrating into the tissue, such as blood vessels, so as to realize the treatment of pathological tissue in the organs. Since the interventional therapy is through the catheter of the human body itself, the trauma to the human body is small, and the expected medical effect can be achieved. However, this interventional therapy depends on excellent catheter medical devices. The instruments commonly used in interventional therapy include puncture devices, catheters, sheaths and other components. The sheath is a relatively thick flexible tube, which can be inserted into the human body in advance of the catheter and can be bent in the human body. In order to ensure the mechanical properties of the sheath and realize the corresponding functions such as bending and rotating, the sheath usually includes an inner tube, a braided layer and an outer tube. During the manufacturing process, a heat shrink tube is used, and the inner tube, the braided layer and the outer tube are heated to become one body. After processing, the heat shrink tube needs to be removed, and the finished product needs to be visually detected to see whether the appearance meets the requirements. After passing the inspection, the product can be packaged and shipped. The existing appearance detection generally relies on limit mirrors and other equipment to observe whether there are defects on the surface of the sheath through image recognition or human eye recognition. However, since the sheath has a certain length, it is very inconvenient to observe the surface in the whole length direction, which leads to low efficiency and even missed detection for some areas. If a device can realize the translation and rotation of the sheath, the detection efficiency of the whole surface of the sheath can be greatly improved. Through the automatic displacement of the sheath realized by the device, the labor intensity can be greatly reduced by cooperating with the human eye or image processing device. CONTENT OF THE UTILITY MODEL

[0003] The utility model aims at overcoming the defects of the prior art, and provides a sheath product detection device for sheath preparation.

[0004] Technical solution: a kind of detection device for sheath preparation, including bottom plate, fixed at the horizontal slide rail of bottom plate, slide seat installed at horizontal slide rail, support unit installed at horizontal slide rail, first vertical plate fixed at bottom plate, second vertical plate fixed at bottom plate, first motor installed at first vertical plate, first bearing installed at second vertical plate, screw rod connected between first motor and first bearing and microscope unit located above bottom plate;The slide seat has a threaded hole matched with the screw rod, and the support unit includes a sliding block mounted on the horizontal slide rail, a support vertical plate connected to the sliding block, and an arc support plate connected to the support vertical plate;The slide seat is L-shaped, and the slide seat is connected with two mounting plates, the mounting plate has a through hole portion, the second bearing is installed at the through hole portion, and the two second bearings are connected with the rotating cylinder, the rotating cylinder has a first clamping plate and a second clamping plate, the first clamping plate is connected to the rotating cylinder by a connecting plate, the second clamping plate is connected with two guide rods, the rotating cylinder has two guide holes matched with the guide rods, the guide rod is sleeved with a spring located between the second clamping plate and the rotating cylinder, the rotating cylinder is fixed with a gear ring, a rotating shaft is installed between the two mounting plates, the rotating shaft is installed with a first gear and a second gear engaged with the gear ring, one of the mounting plates is installed with a second motor, and the second motor is driven with a driving gear engaged with the second gear.

[0005] Further, the two ends of the rotating shaft are connected with the mounting plate through the rotating shaft bearing;The number of teeth of the first gear is less than that of the second gear.

[0006] Thus, the rotation of the rotating shaft is smoother, and better gear ratio transmission is achieved through the engagement between the gears.

[0007] Further, the first clamping plate and the second clamping plate each have an arc surface matched with the sheath.

[0008] Thus, the sheath is better clamped.

[0009] In some embodiments, the clamping plate has a rubber pad, so as to avoid damaging the sheath.

[0010] Further, the end portion of the guide rod is fixed with an end plate.

[0011] Thus, it is easier to pull the guide rod apart through the end plate for clamping the sheath.

[0012] Further, the number of support units is more than 4, and is equally spaced;The slide seat and all support units are fixedly connected by a horizontal connecting rod.

[0013] Thus, support is formed on the sheath in the entire length direction of the sheath, so as to avoid damaging the surface of the sheath by dragging the sheath.

[0014] Furthermore, the slide block and the sliders of all the support units have through holes through which the horizontal connecting rod passes, and the through hole positions are fixedly connected to the horizontal connecting rod.

[0015] Thus, the movement of the slide can enable the movement of the support unit, thereby ensuring that the support unit always provides support to the sheath.

[0016] Beneficial effects: The detection device of this application can move and rotate the sheath tube at the same time during detection, so that the entire surface can be detected along the entire length direction by a microscope.

[0017] In the detection device of this application, the sheath is always supported by the support unit during detection, thereby protecting the sheath and preventing damage to the sheath. Attached Figure Description
