Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a rotator cuff suturing gun. Background Art

[0002] The rotator cuff is an important component of the shoulder joint, composed of four muscles and their attached tendons. It is responsible for the stability and movement performance of the shoulder joint. Rotator cuff injury, especially rotator cuff tendon tear, is a common and serious shoulder joint disease, usually caused by trauma, overuse or aging. Once rotator cuff injury occurs, it often leads to shoulder joint dysfunction, pain and limited movement, seriously affecting the patient's quality of life.

[0003] Rotator cuff repair surgery is a common method for treating rotator cuff injuries. It aims to reconnect the ruptured tendon to the bone and restore its normal function. Traditional rotator cuff repair surgery usually relies on manual operation. The doctor fixes the tendon to the bone through meticulous sutures. However, the traditional method has some challenges, including operation accuracy, operation time and the impact of the doctor's operation experience on the surgical effect. In order to improve the efficiency, accuracy and repeatability of the operation, the rotator cuff suture gun has emerged as a new type of medical device. The rotator cuff suture gun assists surgeons in accurately passing the sutures through the damaged rotator cuff tendon and bone through automation and mechanization, thereby accelerating the tendon repair process, reducing operation time, and reducing the risk of complications and errors caused by improper operation.

[0004] However, the existing rotator cuff suturing gun still has some shortcomings and areas for improvement during actual use. The existing rotator cuff suturing gun can only clamp and position the ruptured tendon, and threading the needle requires a professional doctor to perform another operation. A small amount can be used simultaneously but still needs to be operated in steps and cannot be achieved in one step. At the same time, the existing suturing gun requires the doctor's hand to exert force all the time to ensure clamping and positioning during use, which will increase the doctor's hand fatigue. Therefore, technical personnel in this field provide a rotator cuff suturing gun to solve the problems raised in the above background technology. Summary of the Invention

[0015] (3) Beneficial effects

[0016] The present invention provides a rotator cuff suturing gun. It has the following beneficial effects:

[0017] 1. In the present invention, a needle threading structure is provided. When in use, the front handle and the gun body are pinched. Under the action of the movable connection between the gun body and the lower end of the front handle, the gun body is pushed forward, and the return spring is compressed. The connection angle between the top block and the gun body changes, and the metal needle tube is pushed forward. The shape of the hanging needle and the metal needle tube changes under the restriction of the sinking groove on the upper end surface of the lower clamping nozzle, becoming curved, which can better pierce the patient's skin tissue. At the same time, the surgical suture can be clamped under the action of the hanging needle and then brought to the lower end of the skin tissue to achieve synchronous operation, thereby reducing the overall suturing difficulty. As the doctor's hand releases the squeeze on the gun body, the return spring restores the gun body and the front handle to their original state.

[0018] 2. In the present invention, by setting a clamping structure, when the doctor pushes the gun body forward during use, the connection between the arc groove on the side wall of the arc plate and the insertion rod will continue to push the arc plate forward. At the same time, the first push rod is driven upward under the action of the hinge seat, and the second push rod is pulled downward under the rotation of the turntable, thereby dragging the connecting tube backward. At the same time, under the movable connection between the connecting tube and the upper splint, the rear side of the upper splint is restricted by the front end of the gun barrel, thereby lifting the front end of the upper splint upward, which is convenient for the doctor to perform clamping and positioning operations. By being consistent with the pushing direction of the needle-threading structure but in the opposite direction of operation, the overall operation is more convenient, achieved in one step, and also reduces the doctor's hand fatigue.

[0019] 3. In the present invention, a limiting structure is provided. When in use, the reset spring is squeezed by squeezing and holding the gun body and the front handle. Then the doctor can use his fingers to pull the movable plate to the front side, so that the movable plate moves in a circle with the connecting rod as the center, thereby clamping the positioning groove on the upper end of the positioning rod. Under the connection between the movable plate and the positioning rod, the overall limiting operation is completed, thereby fixing and limiting the clamping position, providing convenience for the doctor's hands.

The edges of the front handle 1 and the gun body 11 are chamfered to ensure comfort when holding.

[0036] Working principle: The present application is a rotator cuff suturing gun. When the doctor pushes the gun body 11 forward during use, the connection between the arc groove 804 on the side wall of the arc plate 805 and the insertion rod 809 pushes the arc plate 805 forward. At the same time, the first push rod 807 is driven upward by the action of the hinge seat 806. The second push rod 808 is pulled downward by the rotation of the turntable 803, thereby pulling the connecting tube 802 backward. At the same time, under the active connection between the connecting tube 802 and the upper splint 801, the rear of the upper splint 801 is The side is restricted by the front end of the gun barrel 6, thereby lifting the front end of the upper splint 801 upward, making it easier for the doctor to clamp and position the gun. By keeping the pushing direction consistent with the needle-threading structure 2 but operating in the opposite direction, the overall operation is more convenient, achieved in one step, and also reduces the doctor's hand fatigue. When in use, by pinching the front handle 1 and the gun body 11, the gun body 11 is pushed forward under the action of the active connection between the gun body 11 and the lower end of the front handle 1, and the reset spring 3 is compressed, and the connection angle between the top block 201 and the gun body 11 is increased. The metal needle tube 203 is pushed forward, and the shape of the thread-hanging needle 204 and the metal needle tube 203 changes under the restriction of the sinking groove 206 on the upper end surface of the lower clamping nozzle 202, becoming curved, which can better pierce the patient's skin tissue. At the same time, the surgical suture can be clamped under the action of the thread-hanging needle 204 and then brought to the lower end of the skin tissue, realizing synchronous operation, thereby reducing the overall suture difficulty. As the doctor's hand releases the squeeze on the gun body 11, the reset spring 3 restores the gun body 11 and the front handle 1 to their original state. When it is necessary to maintain the clamping and fixing state, the gun body 11 and the front handle 1 are squeezed and held, and the reset spring 3 is squeezed. Then the doctor can use his fingers to pull the movable plate 502 to the front side, so that the movable plate 502 moves in a circle with the connecting rod 503 as the center, thereby clamping the positioning groove 504 on the upper end of the positioning rod 501. Under the connection between the movable plate 502 and the positioning rod 501, the overall limiting operation is completed, thereby fixing and limiting the clamping position, providing convenience for the doctor's hands.
