Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an easy-to-operate catheter sheath seat structure. Background Technology

[0002] A catheter sheath is a widely used medical device, primarily used in endovascular interventional procedures or other medical operations that require the insertion of a catheter into the human body.

[0003] A catheter sheath is a hollow, tubular device that can be inserted into a blood vessel or other cavity in the human body, usually made of flexible or semi-rigid materials. Its main function is to provide a stable insertion channel for catheters (such as guidewires, angiography catheters, balloon catheters, etc.) to facilitate smooth catheter entry and manipulation. Simultaneously, the catheter sheath also plays a role in sealing, fixing, and protecting the catheter during surgery. In endovascular interventional procedures, the catheter sheath is an important tool for introducing catheters into blood vessels.

[0004] Existing technologies fail to adequately consider the ergonomics of the catheter sheath seat during use, resulting in a poor feel and negatively impacting the experience of medical staff during surgery. Furthermore, there is a risk of mishandling during use, which can easily lead to improper operation by medical staff, resulting in patient injury or surgical failure, inconvenience to surgical procedures, and increased surgical risks. Therefore, a more user-friendly catheter sheath seat structure is needed to address these issues. Utility Model Content

[0005] To address the problems in existing technologies where the ergonomics of the catheter sheath seat are not adequately considered, resulting in poor handling and negatively impacting the surgical experience for medical staff, and the risk of improper handling leading to patient injury or surgical failure, this invention aims to provide an easier-to-use catheter sheath seat structure to solve the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An easy-to-operate catheter sheath seat structure includes a main body, and a fixing component is provided on the side of the main body;

[0008] The main body includes a sheath seat, and the top and bottom of the sheath seat are provided with widened adhesive positions. The sheath body is provided inside the sheath seat.

[0009] The fixing component includes a retaining ring, the top of which is fixedly connected to a buckle, and the top of which is fixedly connected to an elastic fixing strap.

[0010] As a preferred embodiment of this utility model, the retaining ring moves axially along the sheath seat, and the elastic fixing band surrounds the outer side of the sheath body.

[0011] As a preferred embodiment of this utility model, the sheath seat is a hollow cylindrical structure, and the sheath seat has a tube channel inside, which can accommodate the sheath body.

[0012] As a preferred embodiment of this utility model, the outer side of the sheath seat is provided with anti-slip texture, and the sheath seat is made of medical-grade plastic material.

[0013] As a preferred embodiment of this utility model, the elastic fixing band is made of silicone material, and a tail tube is provided on the side of the widened adhesive area.

[0014] As a preferred embodiment of this utility model, a sealing cap is fixedly connected to the side of the tail tube, and an elastic sealing ring is fixedly connected to the side of the sealing cap.

[0015] As a preferred embodiment of this utility model, the elastic sealing ring is disposed inside the tail tube rod, and the elastic sealing ring is made of rubber material.

[0016] As a preferred embodiment of this utility model, the sealing cap is connected to the tail tube rod via a threaded rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. In this utility model, the widened adhesive sections extending from both sides of the sheath seat provide a larger contact area, allowing medical staff to easily grasp it during surgery. This effectively prevents loosening or displacement due to external forces during use. The widened adhesive sections can better distribute the force, reducing shaking caused by patient movement or improper operation, thereby improving the safety and reliability of the surgery. The widened adhesive sections also provide medical staff with more operating space, facilitating fixation, adjustment, or replacement. This reduces the difficulty of operation and improves work efficiency, especially in emergency situations.

[0019] 2. In this utility model, the sheath body can be adjusted by using a retaining ring that can move axially along the sheath seat. The elastic fixing band is wrapped around the outside of the sheath body, and the sheath body can be fixed and released by tightening and loosening. The sheath seat is a hollow cylindrical structure with a tube channel inside to accommodate the sheath body. The combination design of the elastic fixing band and the retaining ring can firmly fix the sheath body, prevent the sheath body from slipping during the operation, and improve the safety of the operation.
