Description

Technical Field

[0001] This utility model relates to the field of suture equipment technology, and in particular to a simple deep suture equipment. Background Technology

[0002] Deep suturing is a crucial step in surgical procedures, aiming to precisely align deep tissues, reconstruct pathways, and restore function. The technique involves layered suturing, tension reduction, and material selection. To achieve optimal suturing results, it's typically necessary to ensure the needle tip is perpendicular to the wound plane. Since surgical needles are curved, the needle tip often follows an arc path. While this suturing technique can be performed by a surgeon with minimal training on a wound in a relatively undeveloped environment, its precision in deep wounds is often affected by factors such as limited space and visibility. Therefore, this invention addresses this issue. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a simple deep suturing device that can overcome or at least partially solve the above problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A simple deep suturing instrument includes a handle and further includes: an extension rod fixedly connected to the handle, and a support rod fixedly connected to the other end of the extension rod; a rotating shaft rotatably connected to the support rod, and a clamping assembly fixedly connected to the rotating shaft, the clamping assembly holding a surgical needle; the clamping assembly rotates around the rotating shaft to suture the patient's wound, and when the clamping assembly rotates to a limit threshold, the clamping assembly releases its grip on the surgical needle.

[0006] Preferably, the limiting threshold includes 0°-45°.

[0007] Preferably, the clamping assembly includes a movable clamping arm, a first torsion spring, and a fixed clamping arm. The two ends of the first torsion spring are respectively connected to the fixed clamping arm and the movable clamping arm. The first torsion spring provides clamping force to the movable clamping arm and the fixed clamping arm through elastic deformation.

[0008] Furthermore, a rotating rod is fixedly connected to the fixed clamping arm, and a second torsion spring is connected between the rotating rod and the support rod.

[0009] Furthermore, a sliding groove is provided on the rotating rod, and a steel wire rope is slidably connected in the sliding groove. One end of the steel wire rope is fixedly connected to a limit steel ball, and the other end of the steel wire rope is fixedly connected to the handle.

[0010] Furthermore, a second limiting rod and a support plate are fixedly connected to the support rod, and the steel wire rope passes through the support plate.

[0011] Furthermore, a first limiting rod is fixedly connected inside the handle, and the steel wire rope is wrapped around one side of the first limiting rod.

[0012] Furthermore, a compression rod is rotatably connected to the handle, and the compression rod is located on one side of the wire rope.

[0013] Furthermore, a limiting groove is provided on the extrusion rod, and the wire rope is locked in the limiting groove.

[0014] Compared with the prior art, this utility model provides a simple deep suturing instrument with the following advantages:

[0015] 1. This simple deep suturing instrument, by setting an extension rod on the handle and a rotatable clamping component on the support rod, allows the clamping component to extend to the depth of the suture and perform perfect suturing of the wound. This reduces the requirements for suturing technique and avoids the problem of excessive suturing difficulty caused by the narrow internal space during deep suturing.

[0016] 2. This simple deep suturing instrument, by setting a second limiting rod, allows the clamping component to release its grip on the surgical needle after rotating to a certain angle, making it convenient for the user to perform subsequent operations.

[0017] The parts of this device not described herein are the same as or can be implemented using existing technology. This invention reduces the requirements for suturing techniques and avoids the problem of excessive suturing difficulty caused by the narrow internal space during deep suturing. At the same time, it completes the two actions of suturing and releasing the clamping of the surgical needle in one action, simplifying the actions required during suturing and increasing the efficiency of suturing wounds.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example 1: Refer to Figures 1-5 A simple deep suturing instrument includes a handle 1, and further includes: an extension rod 2 fixedly connected to the handle 1, and a support rod 3 fixedly connected to the other end of the extension rod 2; a rotating shaft 44 rotatably connected to the support rod 3, and a clamping assembly 4 fixedly connected to the rotating shaft 44, with a surgical needle 5 clamped on the clamping assembly 4; the clamping assembly 4 rotates around the rotating shaft 44 to suture the patient's wound, and when the clamping assembly 4 rotates to a limit threshold, the clamping assembly 4 releases its grip on the surgical needle 5; the clamping assembly 4 includes a movable clamping arm 41, a first torsion spring 42, and a fixed clamping arm 43, with the first torsion spring 42 providing clamping force to the movable clamping arm 41 and the fixed clamping arm 43.

[0027] In one feasible embodiment, the limiting threshold includes any one of 0°-45°, preferably 15°, 20°, 25°, or 30°.

[0028] In this invention, by setting an extension rod 2 on the handle 1, the clamping component 4 can be extended to the depth of the suture. By fixing a rotating shaft 44 to the clamping component 4, the clamping component 4 can rotate around the rotating shaft 44. When the clamping component 4, carrying the surgical needle 5, makes vertical contact with the skin side of the patient's area to be sutured, by rotating the clamping component 4, the surgical needle 5 can be driven to perfectly penetrate from one side of the wound at an angle of 0°-45° to the other side, thereby automatically completing the penetration suture of the skin at the suture site and achieving a perfect suture effect.

[0029] The clamping assembly 4 consists of a fixed clamping arm 43, a first torsion spring 42, and a movable clamping arm 41. Its shape is similar to that of an aneurysm clamp. Under the action of the first torsion spring 42, the fixed clamping arm 43 and the movable clamping arm 41 will always maintain the clamping state of the surgical needle 5.

[0030] Example 2: Refer to Figures 1-5 Similar to Embodiment 1, but with a further improvement: a rotating rod 46 is fixedly connected to the fixed clamping arm 43, and a second torsion spring 45 connects the rotating rod 46 to the support rod 3. The clamping assembly 4 includes a movable clamping arm 41, a first torsion spring 42, and a fixed clamping arm 43. The first torsion spring 42 provides clamping force to the movable clamping arm 41 and the fixed clamping arm 43. A rotating rod 46 is fixedly connected to the fixed clamping arm 43, and a second torsion spring 45 connects the rotating rod 46 to the support rod 3. A sliding groove 461 is provided on the rotating rod 46, and a sliding groove 461 is formed in the sliding groove 461. A steel wire rope 6 is movably connected. One end of the steel wire rope 6 is fixedly connected to a limiting steel ball 61, and the other end of the steel wire rope 6 is fixedly connected to the handle 1. A second limiting rod 31 and a support plate 32 are fixedly connected to the support rod 3 respectively. The steel wire rope 6 passes through the support plate 32. A first limiting rod 11 is fixedly connected inside the handle 1. The steel wire rope 6 is wrapped around one side of the first limiting rod 11. A pressing rod 12 is rotatably connected to the handle 1. The pressing rod 12 is located on one side of the steel wire rope 6. A limiting groove 121 is opened on the pressing rod 12, and the steel wire rope 6 is stuck in the limiting groove 121.

[0031] In this invention, the fixed clamping arm 43 is fixedly connected to the rotating shaft 44, and the rotating rod 46 is fixedly connected to the fixed clamping arm 43. This allows the fixed clamping arm 43 to rotate synchronously when the rotating rod 46 is subjected to external force, thereby driving the clamping assembly 4 to rotate. The rotating rod 46 has a sliding groove 461, and a steel wire rope 6 is slidably connected in the sliding groove 461. The steel wire rope 6 passes through the support plate 32 fixedly connected to one side of the movable clamping arm 41. When the steel wire rope 6 is pulled, the limiting steel ball 61 is stuck on the outside of the sliding groove 461. The steel wire rope 6 pulls the rotating rod 46 to rotate by moving the limiting steel ball 61. By setting a second torsion spring 45 on the rotating shaft 44, the clamping assembly 4 can automatically reset when not disturbed by external force.

[0032] Two second limiting rods 31 are fixedly connected to the support rod 3. In the absence of external interference, the second torsion spring 45 will drive the clamping assembly 4 to rotate to the side where the fixed clamping arm 43 contacts the second limiting rod 31. When the wire rope 6 is pulled by an external force, the rotating rod 46 drives the clamping assembly 4 to rotate to a certain angle, and the movable clamping arm 41 will abut against the second limiting rod 31. The movable clamping arm 41 and the fixed clamping arm 43 are only connected by the first torsion spring 42. Thus, when the clamping assembly 4 continues to rotate, the movable clamping arm 43 is squeezed by the second limiting rod 31 to generate a displacement relative to the fixed clamping arm 41, thereby releasing the clamping of the surgical needle 5.

[0033] The wire rope 6 passes through the extension rod 2 and is connected to the handle 1. The pressing rod 12 is rotatably connected to the handle 1. When the pressing rod 12 is subjected to external pressure, it rotates and the pressing rod 12 presses the wire rope 6 to move, thereby pulling the wire rope 6 and realizing the rotation operation of the clamping assembly 4. A limit groove 121 is opened on the pressing rod 12, and the wire rope 6 is engaged in the limit groove 121, thereby preventing the wire rope 6 from coming off the pressing rod 12. By setting the first limit rod 11, the stroke of the wire rope 6 when the pressing rod 12 presses the wire rope 6 can be increased.

[0034] When using the device, the user first presses the squeezing rod 12 to the bottom, causing the clamping component 4 to open. The surgical needle 5 can then be placed on the clamping component 4, and the user releases the pressure on the squeezing rod 12 to clamp the surgical needle 5. After preparation, the surgical needle 5 can be inserted into the wound suture site. After adjusting the angle, the user presses the squeezing rod 12 to complete the penetration suture of the surgical needle 5. After the surgical needle 5 has penetrated, the user continues to press the squeezing rod 12 to release the clamp on the surgical needle 5 and then clamp the surgical needle 5 from the other side to pull it out from inside the patient's skin. This process of puncture and suturing is repeated to complete the entire suturing operation.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
