Description

TECHNICAL FIELD

[0001] The utility model relates to anastomosis clamp technical field especially relates to a kind of anastomosis clamp of release line can fall off. BACKGROUND

[0002] Anastomosis clamp is a kind of medical instrument used in surgical operation, mainly used in minimally invasive surgery. Its main function is to realize the anastomosis of tissue in the surgical process, i.e. connecting or closing the pipeline, blood vessel or organ inside the body. The anastomosis clamp can be installed on a gastroscope, and can be used for medical instruments for treatment of digestive tract diseases. This system mainly consists of a clip cap, a hand wheel, a clip and a secondary clipper.

[0003] When releasing the elastic clip, the hand wheel needs to be rotated to move the release line, and the elastic clip is released by the release line. However, the release line on the existing anastomosis clamp is generally fixedly connected with the clip cap body, and the clip cap body is fixedly connected with the gastroscope. This connection mode cannot confirm whether the elastic clip is released when releasing the elastic clip, so the doctor may continue to rotate the hand wheel to contract the release line, which may cause the gastroscope to bend driven by the release line, possibly damaging the gastroscope. After the release of the elastic clip is completed, the release line cannot be taken out from the gastroscope. The release line needs to be taken out from the head end of the gastroscope after the gastroscope is taken out. The release line in the gastroscope will affect the subsequent operation, and the release line needs to be pulled out, which will increase the pain of the patient. SUMMARY

[0011] Optionally, the elastic connecting ring is fixedly provided with an elastic connecting block, and the protruding part is fixedly provided on the elastic connecting block.

[0012] Optionally, the connecting head is provided with a supporting and releasing mechanism, the supporting and releasing mechanism prevents the elastic clamp from falling off when the elastic clamp is static, and reduces the friction between the connecting head and the elastic clamp when the elastic clamp is released.

[0013] Optionally, the supporting and releasing mechanism comprises a groove provided in the connecting head, an arc-shaped guide groove is provided in the groove, a supporting rod is fixedly provided on the protruding part, and the supporting rod abuts against the inner wall of the groove.

[0014] Optionally, when the supporting rod abuts against the inner wall of the groove, the protruding part is expanded outward, and when the supporting rod is located in the arc-shaped guide groove, the protruding part is contracted inward.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Example

[0025] like Figures 1-2 As shown, this utility model proposes a release line detachable fitting clip, including a clip cap body 1 and an elastic clip 2 clamped on the clip cap body 1. The elastic clip 2 is made of an elastic shape memory alloy. The end face of the clip cap body 1 can be... Figure 1 The flat-mouth structure in the middle can also be Figure 2 The U-shaped structure in the design, achieved by using a shape memory alloy, gives the elastic clip 2 strong elasticity. It also includes a release line 3 movably mounted on the clip body 1, one end of which is movably wound around the elastic clip 2, and the winding position is not fixed. Figure 1 and Figure 2 The present invention provides a winding method. The purpose of winding is to move the elastic clip 2 by pulling the release line 3, which is achieved through friction between the release line 3 and the elastic clip 2. One end of the release line 3 is wrapped with a knot. By pulling the release line 3, a tension is applied to the elastic clip 2. This tension causes the elastic clip 2 to detach from the clip body 1 and clamp the lesion tissue under the action of elasticity. Since the release line 3 is not fixedly connected to the elastic clip 2, it can be removed from the endoscope by continuously pulling the release line 3. This prevents the release line 3 from getting tangled in the endoscope, thus avoiding damage to the endoscope and preventing the release line 3 from affecting subsequent endoscopy operations. The release line can be removed without removing the endoscope.

[0026] Furthermore, two protrusions 4 are fixedly installed on the clip body 1, supporting the elastic clip 2. The connection between the clip body 1 and the elastic clip 2 is a conical structure. By having the two protrusions 4 contact the elastic clip 2, the area between the elastic clip 2 and the clip body 1 is effectively reduced, thereby reducing the friction between them and facilitating the detachment of the elastic clip 2 from the clip body 1, thus reducing resistance during release. The conical structure design converts the clamping force applied by the elastic clip 2 to the clip body 1 into a sliding force along the conical direction, further facilitating detachment. This allows the elastic clip 2 to be released even when subjected to a small tension from the release line, ensuring that the elastic clip 2 can be released even when the release line 3 is movably connected to the clip body 1 and wound around it.

[0027] Furthermore, the clip body 1 is provided with a recessed portion 6, and the elastic clip 2 is provided with a protrusion corresponding to the recessed portion 6. Through the cooperation between the recessed portion 6 and the elastic clip 2, it can be ensured that the elastic clip 2 is firmly held on the clip body 1 when it is not subjected to the tension of the release line 3.

[0028] like Figures 1-4 As shown, the clip body 1 includes an elastic connecting ring 101. A base 102 is fixedly installed at one end of the elastic connecting ring 101, and a connector 103 is fixedly installed at the other end of the elastic connecting ring 101. The connector 103 is a tapered structure that gradually tapers away from the elastic connecting ring 101, and the elastic clip 2 is installed on the connector 103. The tapered structure design reduces the resistance encountered by the elastic clip 2 when it moves on the connector 103. When the release line 3 is pulled to apply tension to the elastic clip 2, the friction between the elastic clip 2 and the connector 103 will cause the connector to move. The elastic connecting ring 101 ensures that the connector 103 can move within a certain range.

[0029] The elastic connecting ring 101 is fixedly mounted with an elastic connecting block 401, and the protrusion 4 is fixedly mounted on the elastic connecting block 401. A support release mechanism is provided inside the connector 103. When the elastic clip 2 is stationary, the support release mechanism prevents the elastic clip 2 from falling off, and reduces the friction between the connector 103 and the elastic clip 2 when the elastic clip 2 is released. The support release mechanism includes a groove 5 inside the connector 103, with an arc-shaped guide groove 501 inside the groove 5. A support rod 502 is fixedly mounted on the protrusion 4, and the support rod 502 abuts against the inner wall of the groove 5. When the elastic clip 2 is not released, the support rod 502 abuts against the inner wall of the groove 5. At this time, the protrusion 4 is in an inward and outward expanding state, which provides resistance to the release of the elastic clip 2, preventing the elastic clip 2 from loosening before release and ensuring the stability between the elastic clip 2 and the connector 103. When the release line 3 is pulled, causing the elastic clip 2 and connector 103 to move, the moving connector 103 will cause the support rod 502 to move into the arc-shaped guide groove 501. At this time, the protrusion 4 will retract inward under the pressure of the elastic clip 2. The protrusion 4 will not exert resistance to the release of the elastic clip 2, ensuring that the elastic clip 2 can be released quickly.

[0030] Working principle: By pulling the release line 3, the release line 3 applies a pulling force to the elastic clip 2. This pulling force causes the elastic clip 2 to detach from the clip body 1 and clamp the lesion tissue under the action of elasticity. Since the release line 3 is not fixedly connected to the elastic clip 2, it can be removed from the endoscope by continuously pulling it. This prevents the release line 3 from becoming entangled in the endoscope, thus avoiding damage to the endoscope and preventing it from affecting subsequent endoscopic procedures. The release line can be removed without removing the endoscope.

[0031] When the elastic clip 2 is not released, the support rod 502 rests against the inner wall of the groove 5. At this time, the protrusion 4 is in an inward and outward expanding state, thus providing resistance to the release of the elastic clip 2 and preventing it from loosening before release, ensuring the stability between the elastic clip 2 and the connector 103. When the release line 3 is pulled, causing the elastic clip 2 and connector 103 to move, the moving connector 103 will cause the support rod 502 to move into the arc-shaped guide groove 501. At this time, the protrusion 4 retracts inward under the pressure of the elastic clip 2. The protrusion 4 will no longer provide resistance to the release of the elastic clip 2, ensuring that the elastic clip 2 can be released quickly.

[0032] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
