Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to an adjustable cardiovascular clip. Background Technique

[0002] During heart or blood vessel surgery, it is often necessary to intubate blood vessels. The current clinical usage method is to directly intubate by hand-held manually. In superficial operations, it is more convenient to directly hold the tube by hand. However, when it is in a special position where a person's hand cannot reach or is not suitable, and hand-held intubation cannot be performed, a special cardiovascular clip is needed for assistance.

[0003] However, since most of the current cardiovascular clips have an arc-shaped groove on the inner side of the clamping end to clamp blood vessels, when the flexible clamping piece inside the groove loses elasticity, it is easy to cause insecure clamping of blood vessels. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides an adjustable cardiovascular clip, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solutions: an adjustable cardiovascular clip, including a blood vessel clip, the blood vessel clip includes a first clamping arm and a second clamping arm. Extension sleeves are arranged on the outer sides of both the first clamping arm and the second clamping arm. Clamping heads are symmetrically arranged at the front ends of the two extension sleeves. Clamping handles are symmetrically arranged at the rear ends of the two extension sleeves. A positioning bolt is installed on the outer side of the extension sleeve near the clamping handle. A clamping ring is arranged on the inner side wall of the clamping head. A blade is arranged on one side of the clamping ring. A toothed piece is arranged on the inner side wall of the clamping head between the blade and the clamping ring.

[0006] As a further scheme of the utility model: a hollow groove is opened on the clamping head at the end of the first clamping arm, and an embedded groove is opened on the clamping head at the end of the second clamping arm.

[0007] As a further scheme of the utility model: a hanging plate is installed on the outer side of the first clamping arm, and a pin is installed on the outer side of the second clamping arm.

[0008] As a further scheme of the utility model: both the toothed piece and the blade are fixedly connected to the clamping head.

[0009] As a further scheme of the utility model: a rotating shaft is installed at the position of the embedded groove and the hollow groove between the two clamping heads.

[0010] As a further scheme of the utility model: the extension sleeve is fixedly connected to the clamping head, and the clamping handle is movably connected to the extension sleeve.

[0011] As a further solution of the present utility model: The positioning bolt is meshed and movably connected with the extension sleeve. The positioning bolt is meshed and movably connected with the extension sleeve.

[0012] As a further solution of the present utility model: The hanging plate is movably connected with the first clamping arm, and the pin is fixedly connected with the second clamping arm.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] The flexible pad inside the clamping ring can be used to clamp the blood vessel during operation. By corresponding the position of the blood vessel to the position of the tooth pieces inside the two clamping heads, the groove shape of the set tooth pieces is consistent with the inner tooth shape structure of the hemostatic forceps. Therefore, the blood vessel can be clamped and treated in case of emergency.

[0015] Control the overall clamping handle inside the extension sleeve to be pulled outwards by a certain length, so as to adjust the overall length of the first clamping arm and the second clamping arm, facilitating the use of the blood vessel clamp. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1-5 shown, this embodiment provides an adjustable cardiovascular clip, including a vascular clip 1, which includes: a first clamping arm 2 and a second clamping arm 3. Extension sleeves 4 are provided on the outer sides of both the first clamping arm 2 and the second clamping arm 3. Both the first clamping arm 2 and the second clamping arm 3 include: a clamping head 7 and a clamping handle 8, and the clamping head 7 and the clamping handle 8 are not connected. Therefore, the overall lengths of the first clamping arm 2 and the second clamping arm 3 can be adjusted. The extension sleeve 4 is fixedly connected to the clamping head 7, and the clamping handle 8 is movably connected to the extension sleeve 4. A positioning bolt 401 is installed on the outer side of one end of the extension sleeve 4 close to the clamping handle 8, and the positioning bolt 401 is meshed and movably connected to the extension sleeve 4. A clamping ring 701 is provided on the inner side wall of the clamping head 7. A cutting edge 703 is provided on one side of the clamping ring 701. A toothed plate 702 is provided on the inner side wall of the clamping head 7 between the toothed plate 702 and the cutting edge 703. Both the toothed plate 702 and the cutting edge 703 are fixedly connected to the clamping head 7.

[0024] As Figures 2-5 shown, in this embodiment, a hollow groove 5 is provided on the clamping head 7 at the end of the first clamping arm 2, and an embedded groove 6 is provided on the clamping head 7 at the end of the second clamping arm 3. A rotating shaft is installed between the two clamping heads 7 at the positions of the embedded groove 6 and the hollow groove 5. A hanging plate 201 is installed on the outer side of the first clamping arm 2, and the hanging plate 201 is movably connected to the first clamping arm 2. A pin 301 is installed on the outer side of the second clamping arm 3, and the pin 301 is fixedly connected to the second clamping arm 3.

[0025] The working principle of the present utility model is as follows: By arranging a clamping ring 701, a toothed plate 702 and a blade 703 inside the clamping head 7, the flexible pad inside the clamping ring 701 can be used to clamp the blood vessel during operation. When the elasticity of the internal flexible pad is lost and it cannot clamp firmly, the position of the blood vessel is aligned with the position of the toothed plates 702 inside the two clamping heads 7. The groove type of the arranged toothed plate 702 is consistent with the inner tooth type structure of the hemostatic forceps. Therefore, when an emergency occurs, the blood vessel can be clamped. At the same time, the blade 703 arranged inside the clamping head 7 can be used for shearing wires or pipes during the operation, reducing the amount of instruments required. Among them, by applying torque to the positioning bolt 401 on the outer side of the extension sleeve 4, the overall clamping handle 8 inside the extension sleeve 4 can be controlled to be pulled outwards by a certain length, thereby adjusting the overall lengths of the first clamping arm 2 and the second clamping arm 3, facilitating the use of the blood vessel clamp 1. And when it is necessary to clamp the blood vessel for a long time, by rotating the hanging plate 201 on the outer side of the first clamping arm 2 and buckling it on the outer side of the pin 301, it is possible to prevent danger caused by the loosening of the fingers.

[0026] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
