Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a urethral continuous dilation support device. Background Technology

[0002] Urethral stricture is a common urological disease, often caused by factors such as trauma, infection, surgical trauma, or congenital developmental abnormalities. Patients often experience symptoms such as difficulty urinating, weak urine stream, urinary frequency, and urgency. In severe cases, it can lead to complications such as urinary retention and kidney damage, seriously affecting quality of life. Urethral dilation surgery is the preferred treatment for mild to moderate urethral stricture because it is relatively simple to perform and less invasive.

[0003] However, traditional urethral dilation procedures often use metal dilators or balloon dilation catheters, which have some shortcomings in their use: Firstly, the grip structure of most existing dilation devices is just a cylindrical handle, which can easily cause slippage when doctors are adjusting the insertion position and angle precisely, affecting the accuracy of operation. Furthermore, the dilation force is entirely controlled by experience, which can easily lead to urethral mucosal damage due to uneven force, and even cause complications such as bleeding and infection. Secondly, although balloon dilation catheters can achieve dilation by inflation, most products lack a continuous and stable support structure and it is difficult to precisely control the expansion scale of the balloon, resulting in unstable treatment effects. Summary of the Invention

[0004] This invention relates to a continuous urethral dilation support device to address the problems of existing dilation instruments, which mostly consist of a cylindrical handle, making it easy for doctors to slip when precisely adjusting the insertion position and angle, affecting operational accuracy. Furthermore, the dilation force is entirely dependent on experience, which can easily lead to urethral mucosal damage due to uneven force. Additionally, balloon dilation lacks a continuous and stable support structure, making it difficult to accurately control the balloon's dilation scale, resulting in unstable treatment effects.

[0005] This invention provides a urethral continuous dilation support device, specifically comprising: a support rod; The rear end face of the support rod is equipped with a fixing seat, the inside of the support rod is provided with a ventilation groove, the front end surface of the support rod is provided with a first slot of T-shaped structure, and the outer end face of the support rod is also provided with a connecting hole. A placement plate is welded to the front end face of the fixed base, and a baffle is installed on the front end face of the placement plate. The lower end of the baffle is fixedly connected to the support rod. A miniature air pump is fixedly installed on the upper surface of the fixed base, and the air outlet pipe at the lower end of the miniature air pump is connected to the ventilation groove inside the support rod. The front insertion rod has an arc-shaped main body and four connecting rods are installed in a ring on the rear end face of the front insertion rod. The rear end face of the connecting rods is fixedly connected to the support rod. An elastic airbag is located between the front insert rod and the support rod, and four connecting rods are located outside the elastic airbag. A sleeve is fitted onto the outside of the support rod, and a protective cover is installed on the front end face of the sleeve. The inside of the protective cover is filled with absorbent cotton. An auxiliary frame is provided, with a locking screw installed on its inner end surface. The locking screw is threaded into a connecting hole on the surface of the fixed base.

[0006] Furthermore, a controller is mounted on the upper surface of the placement plate, and the controller is electrically connected to the micro air pump. Furthermore, a probe rod is installed on the lower end face of the controller, and a pressure sensor is provided at the end of the probe rod. The pressure sensor is electrically connected to the controller.

[0007] Furthermore, a first locking block is installed on the rear end face of the elastic airbag, and a through hole is opened inside the first locking block; a second locking block is installed on the front end face of the elastic airbag.

[0008] Furthermore, a second slot is provided on the rear end surface of the front insertion rod, the second locking block at the front end of the elastic airbag is rotatably connected in the second slot, and the first locking block at the rear end of the elastic airbag is rotatably connected in the first slot on the surface of the support rod.

[0009] Furthermore, the inner end face of the sleeve is in contact with the outer end face of the support rod, a limiting cylinder is installed on the outer end face of the sleeve, the inner end face of the limiting cylinder is threaded, and a bolt is connected inside the limiting cylinder.

[0010] Furthermore, the inner end face of the protective cover is ring-shaped with six inserts, the outer end face of the inserts is conical, and each insert has three inclined barbs installed on its outer end face.

[0011] Furthermore, a handle is installed on the rear end face of the fixed base, and resistance grooves are evenly formed on the outer end face of the handle.

[0012] This invention provides a urethral continuous dilation support device, which has the following beneficial effects: 1. A handle is installed on the rear end of the fixation base, which is convenient for doctors to hold. The resistance groove on the surface of the handle can increase the grip friction and prevent slippage during operation. The surface of the fixation base has a connection hole. The locking screw on the surface of the auxiliary frame is threaded into the connection hole.
