Set up the rib through elastic hinge both sides for V font stable in structure can not warp during the atress, and the hasp of being convenient for is fixed. The cross anti-slip threads are arranged on the inner surfaces of the first clamping arm and the second clamping arm, so that the closed ligating clip cannot slide back and forth or left and right.

Description

Medical ligation clamp

Technical Field

The utility model belongs to the technical field of medical instrument, especially, relate to a medical ligation presss from both sides.

Background

Ligation clips, also known as hemostatic clips, vascular clips, tissue clips, and the like, are mainly used for clamping and closing blood vessels and duct tissues in surgical operations. For example, it can be used for clamping cystic duct and gallbladder artery in cholecystectomy of patients with cholecystitis, calculous cholecystitis, and gallbladder polyp, and has hemostatic and closure effects.

The advantages of the existing polymer ligation clip are well known in the surgical field, such as a CN201120019877.7 tissue clip, but the ligation clip still has the defects of unstable structure, easy distortion and deformation when stressed and poor anti-falling performance, and the situation that the plastic ligation clip slides or is not tightly closed on a blood vessel after being closed or the blood vessel is damaged or necrosed due to too tight clamping and closing can occur, so that potential safety hazards are brought to patients. The search for more suitable solutions remains a subject of research needed by industry workers.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provide a medical ligation clip with novel structure and convenient use.

The utility model discloses a purpose is realized through following technical scheme, a medical ligature clamp, including first arm lock, second arm lock, be equipped with elastic hinge between first arm lock and the second arm lock, the three constitutes V type body structure, be provided with the hasp groove on the free end of first arm lock, be provided with the hasp on the free end of second arm lock, transversely be provided with first centre gripping post in first arm lock free end left and right sides, the second arm lock free end left and right sides transversely is provided with second centre gripping post, a serial communication port, elastic hinge both sides have the rib, first arm lock, second arm lock internal surface are provided with the protruding anti-skidding line of cross latticed.

Preferably, the first clip arm and the second clip arm are bow-shaped bodies bent in the same direction.

Preferably, the arcuate bodies of the first and second clamp arms have substantially the same radius of curvature.

Preferably, the opening and closing angle of the first clamping arm and the second clamping arm is 60 degrees.

Preferably, the left and right sides of the first clamping column and the second clamping column are symmetrically arranged, so that the effective fixation of the clip applier can be guaranteed, the head is an arc spherical surface, the periphery is smooth and has no edges and corners, and the risk of scratching surrounding tissues can be effectively reduced.

Preferably, the first clamping column and the second clamping column are equal to the elastic hinge in distance.

Adopt above-mentioned scheme, set up the rib in elastic hinge both sides for V font stable in structure can not distortion during the atress, and the hasp of being convenient for is fixed. The cross anti-slip lines are arranged on the inner surfaces of the first clamping arm and the second clamping arm, so that the closed ligation clamp cannot slide back and forth and left and right, and the closing firmness and stability of the tissue clamp are ensured. The first clamping arm and the second clamping arm can be attached to each other, the closing is tight, the force application is uniform, and the clamped blood vessel and the clamped tissue cannot be excessively pressed to lose activity.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a schematic structural view of the anti-slip pattern of the present invention.

In the drawings: 1. a first clamp arm; 2. a second clamp arm; 3. an elastic hinge; 4. a locking groove; 5. locking; 6. a first clamping column; 7. a second clamping column; 8. a reinforcing portion; 9. and (4) anti-skid lines.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings:

as shown in the attached figure 1, the utility model discloses a first arm lock 1, second arm lock 2 set up elasticity hinge 3 between this first arm lock 1 and the second arm lock 2, are a V font body structure between the three. The free end of the first clamping arm 1 is provided with a lock catch groove 4, the free end of the second clamping arm 2 is provided with a lock catch 5, the left side and the right side of the free end of the first clamping arm 1 are symmetrically provided with first clamping columns 6, the left side and the right side of the free end of the second clamping arm 2 are symmetrically provided with second clamping columns 7, and the distances between the first clamping columns 6 and the second clamping columns 7 and the elastic hinge 3 are equal. Set up rib 8 in 3 both sides of elastic hinge for V font stable in structure can not distortion during the atress, and the hasp locking of being convenient for is used more conveniently. The first clamping arm 1 and the second clamping arm 2 are bent towards the same direction and have basically the same labyrinth radius, so that the clamped blood vessel and the tissue are stressed uniformly and tightly, the local necrosis is not easy to occur, and the 60-degree opening and closing angle can meet the use requirements of most surgical operations.

As can be seen from figure 2, the inner surfaces of the first clamping arm 1 and the second clamping arm 2 are provided with crisscross grid-shaped raised anti-slip threads 9, so that the ligation clamp cannot slide back and forth, left and right in the closing process, and the closure is firm and stable.

The above description is only for the preferred embodiment of the present invention and should not be taken as limiting the invention, and any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
