Description

Technical Field

[0001] The utility model relates to a medical auxiliary device, in particular to an automatic suturing device used for clinical surgery. Background Art

[0002] In clinical practice, the use of venous catheterization technologies, such as peripherally inserted central catheters (PICCs) and mid- to long-term catheters, provides important support for patients requiring long-term or mid-term intravenous therapy. After successful puncture and cannulation, securing the catheter is crucial to ensuring its effectiveness and preventing complications.

[0003] In traditional clinical procedures, medical staff often use auxiliary materials to secure intubations in a U-shaped manner. While this method offers the advantage of simplicity and ease, it also suffers from the difficulty in ensuring the stability of the auxiliary materials. This is especially true when the patient turns over or engages in other daily activities. The auxiliary materials can easily loosen or even fall off due to the patient's movements, leading to adverse events such as tube dislocation or unplanned extubation. These events not only increase patient pain but also increase the risk of infection, compromising treatment effectiveness and, in severe cases, posing a serious threat to the patient's life.

[0004] To address this issue, existing technologies often employ more effective and reliable fixation methods, such as suturing. However, in reality, doctors are often unable to suture and secure the catheter immediately after successful placement due to heavy workloads and tight surgical timelines. This exposes the patient's wound to the external environment, significantly increasing the chances of bacterial invasion and the risk of complications. Prolonged wound exposure can lead to local tissue drying, stretching, and bleeding, ultimately causing tissue damage, delaying wound healing, and increasing patient pain. This presents significant risks and hidden dangers during the patient's treatment process. Utility Model Content

[0005] The purpose of the utility model is to provide a clinical automatic suturing device which can quickly suturing and fixing a catheter to reduce medical risks.

[0006] To achieve the above-mentioned purpose, the present invention provides an automatic suturing device, comprising a device body, a base and a top arm respectively connected to the device body, wherein the top arm is arranged opposite to the base;

[0007] The top arm includes an arm body, a suture needle for threading a suture and puncturing the skin, and a threading ring for stabilizing the suture and pulling the suture to the suture needle. The suture needle can be slidably engaged with the arm body. The suture needle is arranged at the front end of the arm body, and the threading ring is arranged on the side of the arm body.

[0008] The base is provided with a centrally swinging shuttle, which is used to cooperate with the suture needle to form a suture on the patient's skin when the suture needle punctures the patient's skin;

[0009] The device body is provided with a winding ring for winding the suture thread and a driving component for controlling the start and stop of the suture needle and the shuttle. The driving component is built into the base and is provided with a start-stop switch for controlling the start and stop.

[0010] Compared with the existing technology, the present invention innovatively introduces an automatic suturing device to meet the demand for rapid suturing and fixation of catheters in clinical practice. During the clinical process, when medical staff complete the catheterization surgery and need to suture and fix the inserted catheter, the automatic suturing device of the present invention is activated. During use, first clamp the patient's skin at the location where suturing and fixation are required between the automatic suturing device of the present invention, and then continuously press the start-stop switch to make the drive component start and stop intermittently. The intermittent start-stop operation of the drive component will drive the suture needle and shuttle to perform suturing operations. When the suture needle punctures downward to penetrate the patient's skin, the suture thread on the suture needle cooperates with the shuttle to bypass the catheter and wrap it around it. When the suture needle is retracted upward, the suture thread is simultaneously lifted upward, thereby fixing the catheter and suturing the wound. During this process, by pressing the start-stop switch, the suture needle and the shuttle can be controlled to be in the started state. The suture needle in the started state repeatedly punctures and rises up in the patient's skin, and cooperates with the shuttle to fix the catheter and form sutures in the patient's skin; finally, when the fixation is completed, release the start-stop switch to stop the movement of the suture needle and the shuttle.

[0011] As can be seen from the above, during the entire use process of the utility model, the driving component controlled by the start-stop switch drives the suture needle and the shuttle, thereby automatically and quickly realizing the suturing and fixing operation on the patient's skin, avoiding long-term exposure of the wound while saving the manpower spent on suturing and fixing work. The use of the utility model improves the efficiency of suture fixing work after tube placement, reduces the rate of accidental extubation and tube removal and the pressure on the clinical front line, and effectively improves the satisfaction of medical staff and patients.

[0012] Optionally, a pressure plate is provided between the top arm and the base, connected to the device body, for clamping the skin to be sutured. The pressure plate and the base are used to clamp the skin portion to be sutured. The pressure plate is movable relative to the portion connected to the device body to accommodate suturing of different skin locations and thicknesses. The pressure plate also ensures that the skin is clamped and prevents displacement during the needle's puncture and recovery process, thereby preventing suture misalignment or other medical accidents.

[0013] Optionally, the pressing plate is further provided with a threading hole for the suture needle to puncture the skin to form a suture. The suture needle passes through the pressing plate through the threading hole and cooperates with the shuttle in the base to complete the suture fixation of the inserted catheter.

[0014] Optionally, a spring for limiting the position of the top arm is further included, and the spring is disposed between the top arm and the pressure plate. The spring between the top arm and the pressure plate allows the top arm to expand upward relative to the pressure plate. The spring allows the angle between the top arm and the pressure plate to increase within the deformation range of the spring, so that when the pressure plate expands upward or compresses downward to adapt to different parts of the body and different thicknesses of skin, it moves synchronously with the expansion of the pressure plate to adapt to treatment needs. At the same time, the provision of the spring allows the top arm to expand / retract relative to the pressure plate to facilitate the insertion of the suture thread in the suture needle.

[0015] Optionally, the device body is further provided with a battery slot for embedding a battery. In the present invention, the battery serves as a direct power source to drive the driving component.

[0016] Optionally, a heat dissipation slot is provided on the main body of the device. The provision of the heat dissipation slot helps to allow external air to enter the interior of the automatic suturing device, thereby dissipating the heat generated by the driving components, suturing needle and shuttle inside the main body of the device during operation through air convection, thereby providing thermal protection for the automatic suturing device of the present invention.

[0017] Optionally, the bottom of the device body is concave toward the center of the device body to form a gripping groove for gripping the device body. The device body with a gripping groove enables medical personnel to better grasp the device during use, reducing the probability of accidents such as slipping during use and avoiding medical safety accidents.

[0018] Optionally, the threading ring includes a threading shaft for winding the suture and a fixing member, and the fixing member can be slidably engaged relative to the threading shaft to stabilize the suture on the threading shaft.

[0019] Optionally, the winding ring includes a winding reel for winding the suture thread and a winding shaft for fixing the winding reel. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] See also Figure 1 As shown, the automatic suturing device of the present invention is used to provide a device for quickly suturing and fixing a catheter during a catheterization operation to reduce medical risks. The automatic suturing device of the present invention includes a device body 1, a base 2 and a top arm 3, wherein the base 2 and the top arm 3 are respectively connected to the device body 1.

[0024] Specifically, the top arm 3 includes an arm body 31, a suture needle 32 for threading a suture and puncturing the skin, and a threading ring 33 for stabilizing the suture and pulling the suture to the suture needle 32. The suture needle 32 can be slidably engaged with the arm body 31. The suture needle 32 is arranged at the front end of the arm body 31. The suture needle 32 is provided with a threading hole 32a for threading the suture. The threading ring 33 is arranged on the side of the arm body 31.

[0025] A centrally swinging shuttle is provided in the base 2, and is used to cooperate with the suture needle 32 to form a suture on the patient's skin when the suture needle 32 punctures the patient's skin;

[0026] The device body 1 is provided with a winding ring 11 for winding the suture thread and a driving component for controlling the suture needle 32 and the shuttle. The driving component is built into the base 2 and is provided with a start-stop switch 12 for controlling the start and stop.

[0027] Compared with the existing technology, the present invention innovatively introduces an automatic suturing device to meet the demand for rapid suturing and fixation of catheters in clinical practice. During the clinical process, when medical staff complete the catheterization operation and need to suture and fix the inserted catheter, the automatic suturing device of the present invention is activated. During use, the skin of the patient at the location where suturing and fixation are required is first clamped between the automatic suturing device of the present invention, and then the start-stop switch 12 is continuously pressed to cause the drive component to start and stop intermittently. The intermittent start-stop operation of the drive component will drive the suture needle 32 and the shuttle to perform suturing operations. When the suture needle 32 punctures downward to penetrate the patient's skin, the suture thread on the suture needle 32 cooperates with the shuttle to bypass the catheter and wrap it around it. When the suture needle 32 is retracted upward, the suture thread is simultaneously lifted upward, thereby fixing the catheter and suturing the wound. During this process, by pressing the start-stop switch 12, the suture needle 32 and the shuttle can be controlled to be in the started state. The suture needle 32 in the started state repeatedly punctures and rises at the patient's skin, and cooperates with the shuttle to fix the catheter and form sutures at the patient's skin; finally, when the fixation is completed, the start-stop switch 12 is released to stop the activities of the suture needle 32 and the shuttle.

[0028] As can be seen from the above, during the entire use process of the present invention, the driving component controlled by the start-stop switch 12 drives the suture needle 32 and the shuttle, thereby automatically and quickly performing the suture fixation operation on the patient's skin, avoiding long-term exposure of the wound while saving the manpower spent on suture fixation work. The use of the present invention improves the efficiency of suture fixation work after tube placement, reduces the rate of accidental extubation and tube removal and the pressure on the clinical front line, and effectively improves the satisfaction of medical staff and patients.

[0029] Specifically, one end of the shuttle is provided with a hook portion, and a portion of the suture thread is stored in the shuttle. When the suture needle 32 punctures downward, the hook portion in the shuttle hooks the suture thread in the suture needle 32 and rotates, so that the suture thread in the suture needle 32 is wrapped around the shuttle, and a knot is formed when the suture needle 32 is withdrawn upward to form a knot to wrap around the catheter and fix it, and finally form a suture on the patient's skin. When the suture needle 32 is withdrawn upward, the shuttle also returns to its original position, waiting for the next time the suture needle 32 punctures the skin again for suturing, and repeats the above-mentioned swinging. Specifically, the shuttle is a prior art, which is a common component in existing sewing machine equipment, such as the shuttle disclosed in Chinese Patent Publication No. CN1214746A and the shuttle disclosed in Chinese Patent Publication No. CN1061113C, which will not be described in detail here.

[0030] Optionally, a pressure plate 4 for pressing the skin to be sutured is provided between the top arm 3 and the base 2, and the pressure plate 4 is connected to the device body 1. The pressure plate 4 and the base 2 are used to clamp the skin portion to be sutured and fixed. The pressure plate 4 can move relative to the portion to which it is connected to the device body 1 to accommodate the suturing needs of skin of different parts and thicknesses, and ensure that the skin is clamped without displacement during the process of the suture needle 32 puncturing the skin and recovering, thereby avoiding suture dislocation or other medical accidents.

[0031] Optionally, the pressing plate 4 is also provided with a threading hole 4a for the suture needle 32 to puncture the skin to form a suture. The suture needle 32 passes through the threading hole 4a through the pressing plate 4 and cooperates with the shuttle in the base 2 to complete the suture fixation work of the inserted catheter.

[0032] Optionally, a spring 5 for limiting the top arm 3 is further included, and the spring 5 is arranged between the top arm 3 and the pressure plate 4. The spring 5 between the top arm 3 and the pressure plate 4 allows the top arm 3 to be expanded upward relative to the pressure plate 4; specifically, the spring 5 is sleeved on the limiting pin 5a. The spring 5 allows the angle between the top arm 3 and the pressure plate 4 to be adjusted within the deformation degree limited by the spring 5 and the limiting pin 5a, so that the pressure plate 4 can adapt to suturing requirements when it is expanded upward / pressed downward when treating skin of different parts and different thicknesses. At the same time, the setting of the spring 5 allows the top arm 3 to be movably expanded / retracted relative to the pressure plate 4 to facilitate the insertion of the suture thread in the suture needle 32.

[0033] Optionally, a battery slot 13 for embedding a battery is further provided on the device body 1. In the present invention, the battery is used as a direct power source to drive the driving component to move.

[0034] Optionally, the device body 1 is further provided with a heat dissipation slot 14 for dissipating heat. The provision of the heat dissipation slot 14 helps to allow external air to enter the interior of the present invention, thereby dissipating the heat generated by the driving components, suture needle 32 and shuttle inside the device body 1 during operation through air convection, thereby providing thermal protection for the automatic suture device of the present invention.

[0035] Optionally, the bottom of the device body 1 is concave toward the center of the device body 1 to form a gripping groove 15 for gripping the device body 1. The device body 1 with the gripping groove 15 enables medical personnel to better grasp the device during use, reducing the probability of accidents such as slipping during use, and avoiding medical safety accidents.

[0036] Optionally, the threading ring 33 includes a threading shaft 331 for winding the suture thread and a fixing member 332 . The fixing member 332 can be slidably engaged with the threading shaft 331 to stabilize the suture thread on the threading shaft 331 .

[0037] Optionally, the winding ring 11 includes a winding reel 111 for winding the suture thread and a winding shaft 112 for the winding reel 111 to rotate freely. During suturing, the suture thread on the winding reel 111 is unwound from the winding reel 111 under the traction of the suture needle 32. At the same time, the winding reel 111 rotates relative to the winding shaft 112 to achieve the unwinding of the suture thread. The design of the winding reel 111 fully considers the winding, storage and use requirements of the suture thread. The disk body of the winding reel 111 is usually designed to be cylindrical with a small diameter in the middle and large on both sides to facilitate the winding of the suture thread. The winding shaft 112 has a smooth cylindrical surface to help the suture thread be wound or pulled out more tightly and orderly to allow the suture needle 32 to use it. More specifically, during the entire use of the present invention, the wire winding ring 11 is used to store new, unused sutures. The sutures in the wire winding ring 11 are guided to the suture needle 32 via the threading ring 33 and are fed into the skin by the suture needle 32 during use, ultimately forming a catheter for fixed insertion of the sutures.

[0038] The principle of the driving component involved in the present invention driving the suture needle 32 and the shuttle to achieve suturing is well known to ordinary technicians in this field and will not be described in detail here.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0040] At the same time, the above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
