Description

Technical Field

[0001] The invention relates to a surgical laparoscopic surgery knotting device Background Art

[0002] Although laparoscopic instrument knotting is often used in clinical practice, it generally requires two laparoscopic surgical instruments to complete the knotting. For single-port laparoscopic surgery, there is often only one laparoscopic surgical instrument that can be used for surgical operations. Conventional laparoscopic instrument knotting, due to the softness of the knotting line itself and the difficulty in tying a knot, often requires the repeated assistance of laparoscopic forceps to bypass the knotted tissue when tying a knot, which is very cumbersome and ineffective. Another way to replace suture knotting is to use titanium clips to treat the tissue that needs to be ligated. The retention of titanium clips in the body has a certain impact on the body, and various complications may occur, and the resulting costs increase the economic burden on patients. There is also a method that pulls the suture out of the body to tie a knot and then uses a knot pusher to push the knot into the abdominal cavity. There are disadvantages such as cumbersome operation and long operation time. The above three methods have their own shortcomings, and there is an urgent need for a knotting device that can solve the above technical problems. Summary of the invention

[0021] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0022] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a list of equivalent or similar features.

[0023] like Figure 1-3 As shown, a surgical laparoscopic knotting device of the present invention includes an operating part 60 and a main body, wherein the main body includes a first main body 10 and a second main body 20 extending along a first direction, wherein the first main body 10 and the second main body 20 are configured to be operated by the operating part 60 to move away from and approach each other around a rotating axis 50, a winding part is arranged on the main body, and the winding part includes a first winding part 30 and a second winding part 40, wherein the first winding part 30 is arranged from the first main body 10 along the second direction, and the second winding part 40 is arranged from the second main body 20 along the second direction, wherein the first winding part 30 and the second winding part 40 are configured to open and close to each other as the first main body 10 and the second main body 20 move away from and approach each other, and a first angle α is formed between the main body (the first main body 10 and the second main body 20) and the winding part (the first winding part 30 and the second winding part 40), wherein the first angle α is set to an acute angle, and the optimal angle of the first angle α is set to 45 degrees.

[0024] The main body and the winding part of the present invention are arranged at an acute angle and the two are surrounded by a winding area 1 in the acute angle area. During the suturing and knotting process, the suture is placed in the winding area 1, and the winding part is rotated to form a coil of the suture. Then the operation part 60 is manipulated to open and close the main body to drive the winding part to open, and the winding part is used to clamp the suture at the other end into the coil of the winding part to complete the knotting (hereinafter combined with Figure 6-7 Detailed description of the winding and knotting process).

[0025] like Figure 2 As shown, in the present invention, a wire clamping portion (31 / 41) is provided on the winding portion (first winding portion 30, second winding portion 40) extending in a direction away from the winding area 1, and the wire clamping portion is configured to open and close as the winding portion opens and closes.

[0026] In the present invention, a serration portion (32 / 42) is provided on the wire clamping portion to facilitate wire clamping.

[0027] like Figure 3As shown, in the present invention, the main body (first main body 10, second main body 20) and the winding part (first winding part 30, second winding part 40) are arranged to be located in two planes, and the projections of the two along the vertical direction are arranged to cross to form a second angle β, wherein the second angle β is set to an optimal angle of 45 degrees. The winding part and the main body are not located in the same plane but are arranged to cross, which makes it easier to perform the clamping operation after the winding part is wound, without the need to adjust the clamping angle.

[0028] like Figure 4 As shown, in the second embodiment of the present invention, an extension portion (11 / 21) is provided on the main body portion (first main body portion 10, second main body portion 20) extending along the third direction, and the winding portion and the extension portion are arranged to present a V-shape or a U-shape. This arrangement makes it easier to operate the wire clamping operation after the winding portion is wound, and the operation range is smaller.

[0029] In the present invention, the winding portion and the extension portion are two sides of a V-shape or a U-shape, and the lengths of the two are different. This arrangement can prevent the wire from getting hung during the winding process.

[0030] like Figure 5 As shown, in this embodiment, the operating part 60 drives the main body to open and close, which is the structure of the laparoscopic surgical forceps in the prior art, such as the structure of the operating part 60 driving the main body disclosed in CN201010234653.8 or the laparoscopic surgical forceps disclosed in Baidu Library https: / / wenku.bAidu.com / view / 0e2dc0AAe43A580216fc700Abb68A98271feAc0d.html, which includes a rotating part 70 that can drive the main body to rotate to facilitate winding.

[0031] The following will be combined Figure 6-Figure 7 The present invention describes in detail a process of winding and knotting a surgical laparoscopic knotting device. For example, during a laparoscopic operation, one person operates the knotting device while the other person holds a needle holder to perform a suture and pull suture operation. After the needle and thread pass through tissue C (incision / suture opening), line A is the outlet end, which is located above line B. The end of line A is gently pulled (line A is pulled during the entire knotting process), the winding part is operated to place line A in the winding area 1, and the rotating part is turned to rotate and knot (the existing laparoscope rotating part is designed to rotate 1 The wire A will be wound around the winding part to form a coil with a buckle. The operating part is operated to open the main body. At this time, the wire clamping part and the winding part are also opened to expand the coil. The wire clamping part clamps the end of the B wire. The rotating part is rotated to expand the coil. The wire clamping part clamps the B wire and passes it through the expanded coil smoothly. Then, the B wire and the A wire are tightened respectively to form the first knot. The subsequent installation operation forms the second knot, forming a standard surgical knot. The subsequent knotting is done by analogy.

[0032] It should be noted in the present invention that the main body and the operating part can be a general surgical forceps structure or a laparoscopic surgical forceps structure in the prior art. In addition, the first main body 10 and the second main body 20 can rotate around the rotation axis 50, and the two can rotate around the same rotation axis or around different rotation axes respectively. The first main body 10 and the second main body 20 can move away from and approach each other in an arc around the rotation axis, and the opening method of the two can be fan-shaped opening or parallel opening. Similarly, the first winding part 30, the second winding part 40, and the clamping part (31 / 41) are the same when opened and closed. Closing means that at least a part between the two can clamp the suture line, and it is not mandatory to require the entire structure to be completely fitted.

[0033] In summary, the surgical laparoscopic knotting device of the present invention has a simple structure and can quickly and smoothly complete knotting during surgery, especially in laparoscopic surgery and other surgeries with small operating space, with good effects, reducing the doctor's workload and facilitating successful surgery for patients.

[0034] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
