Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to a kidney surgery clamp. Background Art

[0002] The kidney is one of the important organs in the human body, with the physiological functions of excreting metabolic products and regulating water and electrolyte balance. In kidney surgery, especially nephrectomy, it is usually necessary to use a clamp to clamp the blood vessels and ureters connected to the kidney to assist in the fixation of the kidney and the surgical operation of the blood vessels and ureters. However, the existing clamp usually extends the hemostatic clamp into the patient's body through the surgical incision, and squeezes the clamp to close the hemostatic clamp on the blood vessel. In this way, the clamp needs to be repeatedly taken out and put in for multiple uses of the hemostatic clamp, which increases the workload of the doctor and the risk of infection for the patient.

[0003] In the prior art, multiple hemostatic clips are pre-stored and delivered to the end of the clamp through a push-pull structure, thereby forming a continuous hemostatic clip clamping operation. In this method, multiple clamping operations are still required, and the clamping operations of multiple hemostatic clips cannot be completed at one time, which is not conducive to reducing the workload of doctors and increases the risk of infection caused by exposure in the patient's body. An auxiliary driving mechanism is used to move the sleeve toward the distal side to partially close the jaw assembly, thereby completing the effect of delivering the hemostatic clip. In this method, when the hemostatic clip is delivered into the incision by the clamp, there is a lack of fixation of the hemostatic clip, and when the clamp works to close the hemostatic clip, there is a lack of ejection of the hemostatic clip, which makes it easy for the hemostatic clip to fall off when it is delivered to the patient's incision and is not easy to detach from the clamp when clamping the blood vessel, thereby affecting the progress and effect of the operation. Summary of the invention

[0047] The drainage mechanism includes a drainage tube 6, and the bottom of the shear groove 53 on the lower clamping block 52 is connected to a drainage port 513, and the lower end of the drainage port 513 is connected to a connector 510. One end of the drainage tube 6 is connected to the end of the connector 510 away from the shear groove 53, and the other end is connected to the input end of the external negative pressure bottle, and a valve is installed.

[0048] The drainage mechanism also includes a second connecting rod assembly, which includes a connecting rod 1 57. One end of the connecting rod 1 57 is hinged in the shear groove 53 of the upper clamping block 51, and the other end is hinged with a connecting rod 2 512. A support block is fixedly connected to the bottom of the shear groove 53 on the lower clamping block 52. The middle part of the connecting rod 2 512 is hinged to the top of the support block, and a sealing plug 58 is hinged at the end away from the connecting rod 1 57. The sealing plug 58 is elastic and is sealed and clamped in the drainage port 513.

[0049] There are two drainage ports 513 , connectors 510 , second connection components and seals 58 , which are symmetrically spaced on both sides of the shear mechanism. The end of the drainage tube 6 is connected to a Y-type connecting pipe 61 , and is connected to the ends of the two connectors 510 through the Y-type connecting pipe 61 .

[0050] Two hemostatic clips located on one side of the shearing mechanism are close to the spine, and one hemostatic clip located on the other side of the shearing mechanism is close to the kidney, so as to conveniently clamp the blood vessels or ureters at the corresponding positions.

[0051] The present invention is applied to the clamping of blood vessels and ureters in open nephrectomy surgery. The attached figure in the text is a schematic diagram of a right kidney clamp, and the clamping head 5 of the left kidney clamp is a mirror image of the clamping head 5 of the right kidney clamp;

[0052] The hemostatic clip is installed in the hemostatic clip installation slot 54. During the operation, the doctor holds the fixed clamp handle 1 of the clamp and drives the clamp head 5 to close by holding the clamp handle 2 to clamp the renal blood vessels. The rotating wheel 4 adjusts the angle of the clamp head 5.

[0053] A joint 510 is provided at the bottom of the lower clamping block 52 to support quick replacement of the pipeline. The joint 510 is connected to the drainage tube 6 through a Y-type pipe 61. The end of the drainage tube 6 is connected to the negative pressure bottle. During the operation, the negative pressure instrument is turned on to generate negative pressure in the negative pressure bottle. The doctor cuts the patient's affected area and finds the kidney and its blood vessels and ureters. The doctor holds the clamp and extends the clamp tube 3 from the incision into the patient's body. The doctor ensures that the opening of the clamp head 5 is facing the blood vessel or ureter and then gently touches the clamp head 5 against the blood vessel or ureter. The doctor holds the clamp handle 2, the clamp head 5 is merged, and the three hemostatic clips installed in the clamp head 5 are clamped on the blood vessel or ureter. The clamp head 5 is provided with three hemostatic clip installation grooves 54 to ensure that the first hemostatic clip is clamped near the kidney and the second and third hemostatic clips are clamped near the spine.

[0054] At the same time, when the clamping heads 5 are combined, the blade 511 in the shearing groove 53 between the first hemostatic clip and the second hemostatic clip shears the blood vessel or ureter;

[0055] When cutting the blood vessel or ureter, the clamping head 5 is closed to make the connecting rod 1 57 press down the connecting rod 2 512, and the connecting rod 2 512 is rotated by the lever principle under the support of the pillar, and the sealing plug 58 at the other end of the connecting rod 2 512 is pulled up, and the body fluid exuded when the blood vessel or ureter is cut is absorbed and drained into the negative pressure bottle under the action of negative pressure;

[0056] When the clamping head 5 is reset, the plug 58 seals the drainage port 513 under the downward pressure of the connecting rod 2 512 to prevent the plug from adsorbing other tissues of the patient and causing damage to the patient. The doctor cuts the blood vessels and ureters in turn, separates the adrenal gland from the kidney, and then removes the kidney.

[0057] The multiple hemostatic clip installation slots 54 of the clamping head 5 are arranged to reduce multiple clamping operations to one clamping operation, and the shearing operation is performed simultaneously during clamping, thereby reducing the workload of doctors and saving time, and reducing the exposure time of patients. The drainage of the drainage tube 6 prevents the leakage of body fluids to reduce the cleaning work of doctors, and prevents the leaked body fluids from infecting other tissues of the patient and obstructing the doctor's sight, thereby reducing the burden on doctors and reducing the risk of infection for patients.

[0058] Before the operation, the hemostatic clip is installed in the clamping head 5 in advance. When the limiting protrusion of the hemostatic clip is inserted into the positioning groove 56, the limiting block 516 is pressed out of the positioning groove 56 along the wedge-shaped inclined surface of the limiting block 516 to overcome the elastic force of the spring 519. After the limiting protrusion of the hemostatic clip is inserted into the positioning groove 56, under the elastic force of the spring 519, the limiting block 516 is reset and extends into the positioning groove 56 to form an extrusion limit on the limiting protrusion, thereby improving the stability of the hemostatic clip when it moves with the clamp.

[0059] When the clamping head 5 is merged, the two mutually hinged push rods 551 rotate and close, and the push rod 551 drives the rotating rod 515 to swing toward the bottom of the positioning groove 56 through the hinged small slider, thereby driving the rotating shaft 518 to rotate, and the rotating shaft 518 drives the limiting block 516 to rotate through the square shaft and the slide groove, and the limiting block 516 rotates and the top block 5161 at the bottom of the limiting block 516 rotates and enters the positioning groove 56, so that the limiting protrusion of the hemostatic clip in the positioning groove 56 is pushed out of the positioning groove 56, thereby releasing the fixation of the hemostatic clip;

[0060] When the clamping head 5 is reset, the two push rods 551 rotate to reset, pull the rotating rod 515 to reset through the small slider, and drive the limit block 516 to reset through the square shaft and the slide groove, so that the top block 5161 leaves the positioning groove 56;

[0061] The lifting of the top block 5161 ensures that all hemostatic clips are smoothly detached, and the setting of the limit block 516 ensures that the hemostatic clips will not fall off before clamping. The doctor does not need to control the strength of holding the clamp and reduces the need to reinstall hemostatic clips during surgery, which saves time and reduces the difficulty of operation for the doctor, and prevents the hemostatic clips from falling off and falling into the patient's body. After the hemostatic clips are clamped, the lifting effect of the top block 5161 ensures that they are detached, preventing the hemostatic clips from being pulled open by the clamp or damaging the patient's tissue before they are detached, thereby greatly reducing the occurrence of medical accidents.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
