[0046] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0047] like Figures 1 to 7As shown, this embodiment provides a laparoscopic deep incision auxiliary suturing clamp assembly, comprising a first clamp 1 having a first clamping portion 12 and a second clamp 2 having a second clamping portion 22, wherein the first clamp 1 has a first clamping portion 12 provided with a first needle guide cylinder assembly, and the second clamp 22 has a second clamping portion 22 provided with a second needle guide cylinder assembly;
[0048] The first needle introduction barrel assembly and the second needle introduction barrel assembly are respectively provided with a first needle introduction channel and a second needle introduction channel both in an arc shape;
[0049] The first clamp 1 and the second clamp 2 have two states: separation and assembly;
[0050] When the first clamp 1 and the second clamp 2 are in the assembled state, the centers of the circles corresponding to the first needle introduction channel and the second needle introduction channel coincide with each other.
[0051] In this embodiment, Figure 1 As shown, when the first clamp 1 and the second clamp 2 are in the assembled state, the centers of the circles corresponding to the first needle introduction channel and the second needle introduction channel coincide, so that the suture needle can pass through the first needle introduction channel and the second needle introduction channel at one time for suturing, and in the process of suturing the incision, the first needle introduction channel and the second needle introduction channel guide and constrain the travel trajectory of the suture needle, so that the travel trajectory of the suture needle is separated from the abdominal viscera, thereby avoiding the surgeon's misjudgment or operational error due to a narrow field of view, and assisting the doctor in achieving accurate and safe suturing with the suture needle, thereby reducing the probability of serious surgical complications after suturing.
[0052] Specifically, in this embodiment, the central angles of the first needle introduction channel and the second needle introduction channel are in the range of 10° to 45°. In this embodiment, the central angles of the first needle introduction channel and the second needle introduction channel are the same, both 30°, and those skilled in the art may also set the central angles to other sizes such as 40°, 20°, etc. as needed.
[0053] In this embodiment, if Figures 1 to 5 As shown, the first needle introduction channel includes a first needle introduction channel A131 and a first needle introduction channel B141 both in an arc shape;
[0054] The first clamping part 12 includes two clamping rods, the first needle introduction cylinder assembly includes a first needle introduction cylinder A13 and a first needle introduction cylinder B14 respectively arranged on the two clamping rods, the first needle introduction channel A131 is located in the first needle introduction cylinder A13, and the first needle introduction channel B141 is located in the first needle introduction cylinder B14;
[0055] The first clamping portion 12 has two states: clamping and loosening;
[0056] In the clamping state of the first clamping portion 12, the centers of the circles corresponding to the first needle introduction channel A131 and the first needle introduction channel B141 coincide with each other.
[0057] In this embodiment, the central angle corresponding to the first needle introduction channel A131 is larger than the central angle corresponding to the first needle introduction channel B141. When the size of the first needle introduction channel is relatively large, the technician can also design the first needle introduction channel B141 into other shapes such as a cylindrical channel. The main functions of the first needle introduction channel A131 and the first needle introduction channel B141 are to guide the arc-shaped suture needle and separate the travel trajectory of the suture needle from the organs in the abdominal cavity to avoid operational errors by doctors.
[0058] Specifically, in this embodiment, the end of the first needle guide barrel B14 is provided with a splicing notch 143 for splicing with the second clamp 2;
[0059] The center of the circle corresponding to the first needle introduction channel is set to one side of the first needle introduction tube B14, which can avoid the problem that the first hand-held part 11 of the first clamp 1 and the second hand-held part 21 of the second clamp 2 are too close to each other after the first clamp 1 and the second clamp 2 are assembled, causing inconvenience in operation.
[0060] Specifically, Figure 1 and Figure 5 As shown, the outer side wall of the first needle introduction barrel assembly is also provided with a first clamp-removing seam for splitting the outer side wall of the first needle introduction barrel assembly in a through-type manner;

By setting the first clamping seam, the first clamp 1 can be removed after the suture needle is threaded, which is convenient for subsequent suture knotting.
[0063] Specifically, in this embodiment, the second needle introduction channel includes a second needle introduction channel A231 and a second needle introduction channel B241 both in an arc shape;
[0064] The second clamping part 22 includes two clamping rods, the second needle introduction cylinder assembly includes a second needle introduction cylinder A23 and a second needle introduction cylinder B24 respectively arranged on the two clamping rods, the second needle introduction channel A231 is located in the second needle introduction cylinder A23, and the second needle introduction channel B241 is located in the second needle introduction cylinder B24;
[0065] The second clamping portion 22 has two states: clamping and releasing;
[0066] In the clamping state of the second clamping portion 22, the centers of the circles corresponding to the second needle introduction channel A231 and the second needle introduction channel B241 coincide with each other.
[0067] In this embodiment, Figure 2 As shown, the first clamping part 12 of the first clamp 1 and the second clamping part 22 of the second clamp 2 are both in a clamping state.

At this time, a single threading action of the suture needle is completed. When the incision only needs to be sutured with one stitch, the first clamp 1 and the second clamp 2 are removed from the suture thread, and the suture thread is knotted, and the entire suturing process is completed.
[0068] In this embodiment, if Figure 2 As shown, the end of the second needle guide cylinder A23 is provided with a splicing notch 143 for splicing with the first clamp 1;
[0069] The center of the circle corresponding to the second needle introduction channel is set to one side of the second needle introduction tube A23, which can avoid the problem that the second hand-held part 21 of the second clamp 2 and the first hand-held part 11 of the first clamp 1 are too close to each other after the first clamp 1 and the second clamp 2 are assembled, causing inconvenience in operation.
[0070] In this embodiment, if Figures 6 to 8 As shown, the outer side wall of the second needle introduction barrel assembly is also provided with a second clamp-removing slit for splitting the outer side wall of the second needle introduction barrel assembly in a through-type manner;

By setting the second clamping seam, the second clamp 2 can be removed after the suture needle is threaded, which is convenient for the subsequent suture knotting.
[0073] Specifically, in this embodiment, both sides of the first clamping portion 12 are provided with first needle guide barrel assemblies with the same structure, and both sides of the second clamping portion 22 are provided with second needle guide barrel assemblies with the same structure. By providing two first needle guide barrel assemblies with the same structure and two second needle guide barrel assemblies with the same structure, the doctor can sew two needles at a time when suturing. The trajectory of the suture needle is shown in FIG. Figure 2As shown, the suture needle first passes through the first needle guide barrel assembly and the second needle guide barrel assembly on one side in sequence to complete the suturing of the first needle, and then passes through the second needle guide barrel assembly and the first needle guide barrel assembly in sequence. The movement trajectory of the suture needle is opposite to that of the first needle, until the needle threading process of the second needle is completed after the needle has completely passed through the first needle guide barrel assembly. Subsequently, the suture thread between the two second needle guide barrel assemblies is cut, the first clamp 1 and the second clamp 2 are removed, and then knotting is performed to complete the suturing.
[0074] In this embodiment, the two first needle guide barrel assemblies are respectively welded on both sides of the first clamping portion 12, and the two second needle guide barrel assemblies are respectively welded on both sides of the second clamping portion 22;
[0075] The distance between the two first needle barrel assemblies and the two second needle barrel assemblies on one side away from each other is less than 25 mm. In this embodiment, the distance between the two first needle barrel assemblies and the two second needle barrel assemblies on one side away from each other is 20 mm. Those skilled in the art can set the distance to 25 mm or even 30 mm as needed. If the distance is too large, the first needle barrel assembly and the second needle barrel assembly cannot be inserted into the incision, affecting the doctor's operation.
[0076] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
