Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a rotator cuff suture gun that is easy to operate. Background Technology

[0002] The rotator cuff is an important component of the shoulder joint, consisting of four muscles and their attached tendons. It is responsible for the stability and movement of the shoulder joint. Rotator cuff injuries, especially tears of the rotator cuff tendons, are a common and serious type of shoulder joint disease. They are usually caused by factors such as trauma, overuse, or aging. Once a rotator cuff injury occurs, it often leads to shoulder joint dysfunction, pain, and limited movement, which seriously affects the patient's quality of life.

[0003] Rotator cuff repair surgery, a common treatment for rotator cuff injuries, aims to reconnect the ruptured tendon to the bone and restore its normal function. Traditional rotator cuff repair surgery usually relies on manual operation, where doctors fix the tendon to the bone with meticulous sutures. However, traditional methods have several challenges, including operational precision, operation time, and the impact of the surgeon's experience on the surgical outcome. To improve the efficiency, accuracy, and repeatability of the surgery, the rotator cuff suture gun has emerged as a new type of medical device. The rotator cuff suture gun assists surgeons in precisely passing sutures through the damaged rotator cuff tendon and bone in an automated and mechanized manner, thereby accelerating the tendon repair process, reducing operation time, and lowering the risk of complications and errors caused by improper operation.

[0004] However, existing rotator cuff suture guns still have some shortcomings and areas for improvement in use. Existing rotator cuff suture guns can only clamp and position the ruptured tendon, and the needle threading and suture insertion require a professional doctor to perform the operation separately. A small number can be used simultaneously, but still require step-by-step operation and cannot be achieved in one step, which causes certain inconvenience to the surgeon and increases the surgeon's hand fatigue. Therefore, those skilled in the art have provided a rotator cuff suture gun that is easy to operate to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a convenient rotator cuff suture gun. The handle structure at the rear end drives the pull rod to move backward. Due to the movable connection between the pull rod and the upper clamp, combined with the restriction of the lower clamp's front end on the rear end of the upper clamp, the upper clamp and lower clamp form an open shape, facilitating the clamping and fixation of the patient's skin tissue. Simultaneously, the handle structure at the rear end propels the metal needle tube connected to the suture needle forward along the slot at the upper end of the separator. Restricted by the limiting groove on the upper surface of the lower clamp, the metal needle tube connected to the suture needle is redirected, piercing upward and backward in an arc shape, facilitating the puncture of the patient's skin tissue. The suture needle, in conjunction with the upper clamp, facilitates suture threading and suturing by the surgeon, achieving a one-step operation, providing convenience during surgery and reducing the difficulty for the surgeon.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a convenient-to-operate shoulder cuff stitching gun, comprising a gun body, a grip structure provided on the front side of the gun body, the rear end of the grip structure penetrating through the front sidewall of the gun body and extending into the interior, a connector provided at the upper center of the front sidewall of the gun body, a puncture structure penetrating through the center of the front sidewall of the connector, the rear end of the puncture structure penetrating through the front sidewall of the connector and extending into the interior of the gun body, the puncture structure comprising a sleeve, the sleeve being disposed at the center of the front sidewall of the connector, the sleeve... A partition frame is provided at the front side of the inner center. A lower clamp is fixedly connected to the front side wall of the partition frame inside the sleeve. A slot is provided at the center of the upper and lower end faces of the partition frame. A metal needle tube and a pull rod are respectively provided in the slots at the upper and lower end faces of the partition frame inside the sleeve. The front end of the pull rod is connected to an upper clamp plate through a rotating shaft. The two ends of the rotating shaft are fixedly connected to the two inner side walls of the lower clamp. A limiting groove is provided at the center of the upper end face of the lower clamp. The front end of the metal needle tube passes through the limiting groove and the end is fixedly connected to a hanging needle.

[0007] With the above technical solution, during use, the handle structure at the rear end drives the pull rod to move backward. Due to the movable connection between the pull rod and the upper clamp, and the restriction of the rear end of the upper clamp by the front end of the lower clamp, the upper clamp and the lower clamp form an open shape, which facilitates the clamping and fixation of the patient's skin tissue. At the same time, the handle structure at the rear end pushes the metal needle tube with the hanging needle forward along the slot at the upper end of the separator. Under the restriction of the limiting groove on the upper end surface of the lower clamp, the metal needle tube with the hanging needle is changed in direction and punctures backward and upward in an arc shape, which facilitates puncturing the patient's skin tissue. At the same time, the hanging needle and the upper clamp work together to facilitate the doctor to perform suture, realizing a one-step operation, providing certain convenience in the surgical process, and reducing the difficulty of the doctor's surgery.

[0008] Furthermore, the grip structure includes a handle, the rear end of which penetrates the front sidewall of the gun body and extends into the interior. The sidewalls of the handle are rotatably connected to the two inner sidewalls of the gun body via a rotating rod. An arc-shaped groove is provided at the rear center of each sidewall of the handle. A pusher is located at the rear center of the handle inside the gun body. Connecting rods are fixedly connected to the center of each sidewall of the pusher. The two connecting rods are slidably connected within the two arc-shaped grooves. A second spring is connected to the rear sidewall of the handle. The other end is engaged with the lower center of the inner side wall of the gun body. A toothed groove is provided at the upper center of the front side wall of the handle. A shaped gear is rotatably connected to the inner side wall of the gun body near the toothed groove. A retainer is provided inside the gun body in front of the shaped gear. A rack is provided at the rear center of the lower end face of the retainer. A groove is provided at the center of the lower end face of the rack. A first spring is provided at the upper center of the rear side wall of the pusher. The rear end of the first spring is connected to the rear inner side wall of the gun body.

[0009] With the above technical solution, when in use, by manually squeezing the handle, the second spring provides a certain elastic support to the handle, causing the toothed groove at the upper end of the front side wall of the handle to drive the rack at the lower end of the retainer to move back and forth, thereby pulling a part of the piercing structure backward. At the same time, the pusher pushes the upper part of the piercing structure forward and pulls the first spring at the rear end, so that it completes the piercing and clamping action of the piercing structure. After releasing the hand, the handle returns to its original shape under the elastic pull of the first spring.

[0010] Furthermore, both the rack and the toothed groove mesh with the irregularly shaped gear for transmission;

[0011] The above technical solution uses a special-shaped gear to transmit the force between the toothed groove and the rack, thereby enabling the grip structure to control the puncture structure.

[0012] Furthermore, the front end of the hanging needle is provided with a cutting edge;

[0013] The above-mentioned technical solution allows the blade to effectively pierce the patient's skin tissue, facilitating suturing.

[0014] Furthermore, the shape of the limiting groove is arc-shaped;

[0015] The above technical solution facilitates changing the forward direction of the metal needle tube and the hanging needle during use.

[0016] Furthermore, a serrated clamping groove is provided at the front edge of the center of the lower end face of the upper clamping plate, and a spring piece is provided at the front edge of the center of the upper end face of the upper clamping plate.

[0017] The above technical solution allows for easy clamping of the patient's skin tissue using serrated clamping grooves, while the spring clips are used to hold the sutures and prevent them from slipping during the procedure.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, by setting a handle structure, by manually squeezing the handle, the toothed groove at the upper end of the front side wall of the handle drives the rack at the lower end of the retainer to move back and forth, thereby pulling a part of the puncture structure backward. At the same time, the pusher pushes the upper part of the puncture structure forward and pulls the first spring at the rear end, so that it completes the puncture and clamping action of the puncture structure. After releasing the hand, the handle returns to its original shape under the elastic pull of the first spring, realizing one-step operation and reducing the difficulty of surgery.

[0020] 2. In this utility model, by setting a puncture structure, the pull rod is moved backward by the handle structure at the rear end. Due to the movable connection between the pull rod and the upper clamp, and the restriction of the rear end of the upper clamp by the front end of the lower clamp, the upper clamp and the lower clamp form an open shape, which facilitates the clamping and fixation of the patient's skin tissue. At the same time, the metal needle tube with the hanging needle connected is pushed forward along the slot at the upper end of the separator by the handle structure at the rear end. Under the restriction of the limiting groove on the upper end surface of the lower clamp, the metal needle tube with the hanging needle connected is changed in direction and punctures backward and upward in an arc shape, which facilitates puncturing the patient's skin tissue. At the same time, the hanging needle and the upper clamp facilitate the doctor to perform suture, realizing a one-step operation, providing certain convenience in the operation process and reducing the difficulty of the operation for the doctor.
