Description

Technical Field

[0001] The utility model relates to the field of medical auxiliary equipment, in particular to a sheath fixing clamp. Background Art

[0002] A vascular access sheath is a medical device typically used to provide temporary vascular access during interventional medical procedures, such as cardiac catheterization or vascular cannulation. Sheath fixation is crucial to maintaining vascular access stability, helping to prevent sheath displacement or slippage and reducing complications after vascular access, such as bleeding or infection.

[0003] A sheath clamp is an auxiliary device used to secure the sheath, firmly securing it to the patient's body and providing greater stability. It's suitable for vascular access procedures requiring longer durations. For example, Chinese patent publication number CN215780862U discloses a femoral artery puncture sheath clamp. This clamp, with a tapered tube, is placed around the outer circumference of the femoral artery puncture sheath and secured to the leg with a connecting cord and adhesive tape. This clamp prevents the femoral artery puncture sheath from being removed while maintaining its mobility.

[0004] The above-mentioned existing technology adopts a flexible fixing method, which makes it impossible to completely fix the sheath. When the catheter in the sheath is pulled out, the sheath is easily displaced and shaken. The loosening of the sheath may cause damage to the blood vessels around the puncture point, increasing the risk of bleeding. This is very unfavorable for situations that require precise control of bleeding at the puncture point, such as interventional surgery or catheter intubation. Therefore, we propose a sheath fixing clamp. Utility Model Content

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," "the other end," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description.

[0026] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc. should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0027] like Figures 1-6As shown, a sheath clamp includes a fixing sleeve 2 that is sleeved onto a vascular puncture sheath 1. A first soft plate 3 is fixedly connected to the lower outer surface of the fixing sleeve 2. A sponge 6 is mounted on the first soft plate 3 to increase the contact area between the first soft plate 3 and the fixing sleeve 2. In practical applications, if the first soft plate 3 is fixed to the patient's body using a flexible method, the vascular puncture sheath 1 may become loose. If the first soft plate 3 is fixed to the patient using a rigid method, the position and angle of the vascular puncture sheath 1 may be inconvenient to adjust later. Therefore, a second soft plate 4 is provided below the first soft plate 3 to securely connect to the patient's body. In this embodiment, the second soft plate 4 has a hook surface 41 on one side and a loop surface 42 on the other side. The hook surface 41 and the loop surface 42 adhere to each other to secure the second soft plate 4 to the patient's body. Several adjustment mechanisms 5 are provided between the second soft plate 4 and the first soft plate 3 to adjust the distance between the first and second soft plates 3 and 4.

[0028] If it is necessary to pull the catheter, the distance between the first soft plate 3 and the second soft plate 4 is adjusted to zero through the adjustment mechanism 5, so that the first soft plate 3 and the second soft plate 4 are tightly connected together, which greatly reduces the probability of the vascular puncture sheath 1 loosening; if it is necessary to adjust the position, angle, etc. of the vascular puncture sheath 1, the distance between the first soft plate 3 and the second soft plate 4 is increased through the adjustment mechanism 5, so that the vascular puncture sheath 1 can move slightly.

[0029] Among them, the fixing sleeve 2 is curled to form a tubular structure, and a linear opening 21 is formed at the curling mouth. Several fixing strips 22 are fixedly installed on the outer surface of the fixing sleeve 2. Several insertion holes 23 are opened on the fixing strips 22 along its length direction. The outer surface of the fixing sleeve 2 is fixedly installed with fixing pins 24 that match the number of fixing strips 22, and the fixing pins 24 match the insertion holes 23. The fixing strips 22 and the fixing pins 24 are located on both sides of the opening 21. In this embodiment, two fixing strips 22 are provided and arranged at both ends of the fixing sleeve 2. They are connected to the insertion holes 23 at different positions through the fixing pins 24 to adjust the tightness of the fixing sleeve 2, so that the fixing sleeve 2 can adapt to vascular puncture sheaths 1 of different sizes, thereby improving practicality.

[0030] After the vascular puncture sheath 1 is secured, the distance between the first flexible plate 3 and the second flexible plate 4 is adjusted using an adjustment mechanism 5. Specifically, the first flexible plate 3 is provided with through holes 31 matching the number of adjustment mechanisms 5. In this embodiment, there are four through holes 31, arranged at the four corners of the first flexible plate 3. The adjustment mechanism 5 includes a rope 51 fixedly connected to the second flexible plate 4. The rope 51 passes through the through holes 31 and extends above the first flexible plate 3. The rope 51 is movably sheathed around a housing 53 located above the first flexible plate 3. Two clamps 52 are slidably mounted within the housing 53 along its length. The two clamps 52 are symmetrically arranged around the rope 51. The two clamps 52 move the rope 51 toward each other and clamp it, keeping the housing 53 and rope 51 fixed. The maximum distance between the first flexible plate 3 and the second flexible plate 4 is limited by the housing 53.

[0031] Based on the above solution, in the initial state, the two clamps 52 need to maintain a grip on the rope 51. When the vascular puncture sheath 1 needs to be adjusted, the two clamps 52 need to be moved away from the rope 51 to facilitate the movement of the housing 53. Specifically, the clamps 52 are L-shaped. The end of the clamp 52 away from the rope 51 is movable through the housing 53 and fixedly mounted with a handle 522. The end of the clamp 52 close to the rope 51 is mounted with a spring 524, which is arranged along the length of the housing 53. In the initial state, the spring 524 applies a thrust to the clamps 52, causing the two clamps 52 to move toward each other. When adjusting the vascular puncture sheath 1, the two handles 522 are pressed simultaneously, causing the two clamps 52 to move away from each other. At this time, the housing 53 can move freely on the rope 51. After releasing the handles 524, the clamps 52 are pushed back to their original position, preventing the housing 53 from moving.

[0032] In order to increase the clamping force of the splint 52 on the rope 51, in this embodiment, a semicircular arc block 521 matching the rope 51 is installed at the end of the splint 52 close to the rope 51. The semicircular arc block 521 increases the contact area between the splint 52 and the rope 51, thereby increasing the clamping force.

[0033] Since the splint 52 is L-shaped, it is easy to deviate to one side during movement, which causes the splint 52 to move unsmoothly. Therefore, in this embodiment, a guide rod 523 is installed at the end of the handle 522 close to the shell 53. The guide rod 523 is movable and passes through the shell 53. The guide rod 523 plays a guiding role to prevent the splint 52 from deviating during movement.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
