Description

Technical Field

[0001] The angle adjustment device of the suture needle holding assembly of the disposable laparoscopic suture device of the present invention relates to a medical device, especially the technical field of laparoscopic suture devices, and is used in conjunction with the disposable laparoscopic suture device, and is suitable for use as a suture device for abdominal, thoracic and urological surgery. Background Art

[0002] At present, laparoscopic staplers with anastomotic needles are used for cutting and anastomosis in laparoscopic surgery. Recently, a surgical linear laparoscopic stapler has been used to replace the manual needle-thread anastomosis operation in surgery. It is being used for anastomosis operations of human respiratory organs and urogenital tracts, operations to form organ channels, and operations to close incisions. It is particularly suitable for anastomosis operations of organs and tissues that are difficult to expose and operate, and can improve the quality of surgery.

[0003] However, the above-mentioned staplers are reusable staplers, which are expensive and need to be thoroughly disinfected for each operation. They cannot be disassembled during disinfection, which makes disinfection difficult and incompleteness may cause cross infection. In addition, repeated use may cause instrument wear, affect the uncertainty of instrument function, and reduce the quality of surgery. Therefore, disposable staplers are needed to ensure the use status and sanitary conditions to ensure the success rate of surgery.

[0004] The existing suture needle holding assembly angle adjustment device is not structurally perfect and is not convenient to use. Summary of the invention

[0005] The purpose of the present invention is to address the above-mentioned deficiencies and to provide an angle adjustment device for the suture needle holding assembly of a disposable laparoscopic suturer, which is used in conjunction with the disposable laparoscopic suturer and is suitable for use as a suture instrument for abdominal, thoracic and urological surgeries.

[0006] The angle adjustment device of the suture needle holding assembly of the disposable laparoscopic suture device is realized by adopting the following technical scheme: the angle adjustment device of the suture needle holding assembly of the disposable laparoscopic suture device includes a joint head swing mechanism, a joint connecting rod 1, a joint connecting rod 2, an operating rod, an angle controller, a rotating connecting rod and a fixed handle.

[0007] The joint head swing mechanism comprises a steering sleeve, a first positioning pin, a left joint head, a roller, a right joint head, a second positioning pin and a joint container.

[0008] The joint container is provided with a joint container cavity and a joint container through hole.

[0009] There are two rollers, which are installed between the left joint head and the right joint head through roller shafts, one end of the joint connecting rod is movably connected to one of the roller shafts, and the other end passes through the through hole of the joint container and is connected to the second joint connecting rod. The left joint head and the right joint head are respectively installed in the joint container cavity through the first positioning pin and the second positioning pin, and can swing in the joint container cavity.

[0010] One end of the steering sleeve is fixedly connected with the left joint head and the right joint head, and the other end is fixedly connected with the rear ends of the left cover plate and the right cover plate of the suture needle holding assembly.

[0012] The front end of the joint connecting rod 2 is provided with a joint connecting rod connecting head, which is used to cooperate with the joint connecting rod connecting hole of the joint connecting rod 1 for compression connection, and the rear end of the joint connecting rod 2 is provided with a corner connecting pin hole.

[0013] The operating rod is sleeved outside the joint connecting rod 1 and the joint connecting rod 2, the front end of the operating rod is fixedly connected to the rear end of the joint container, and the rear end of the operating rod is fixedly connected to the rotating connecting rod.

[0014] The angle controller is installed in an angle controller installation slot provided at the front end of the fixed handle.

[0015] The angle controller includes an angle dial, an angle controller upper cover, an angle shaft, an angle controller lower cover, and an angle connecting pin. An angle scale is provided on the outer circumference of the angle dial, an eccentric angle connecting pin hole is provided on the angle dial, and an angle shaft fixing installation hole is provided in the middle of the angle dial. The angle controller upper cover and the angle controller lower cover are fixedly installed together through the angle shaft. The angle dial is fixedly installed on the upper end of the angle shaft.

[0016] The rotating connecting rod is provided with an open slot, and the joint connecting rod 2 passes through the operating rod and enters the opening of the rotating connecting rod. The corner connecting pin adopts an L-shaped corner connecting pin, one end of which is clamped in the corner connecting pin hole of the joint connecting rod 2, and the other end is clamped in the eccentric corner connecting pin hole of the corner turntable.

[0017] The angle adjustment device of the suture needle holding assembly of the disposable laparoscopic suturer is used in conjunction with the disposable laparoscopic suturer. The upper and lower covers of the angle controller are rotated to drive the angle turntable to rotate through the angle shaft, and then the joint connecting rod 2, the joint connecting rod 1 and the left and right joint heads are pulled through the angle connecting pin. The suture needle holding assembly is driven to swing back and forth through the steering sleeve. The swinging angle is ±45 degrees, which improves the adaptability of the stapler, can be aligned with the patient's required anastomosis tissue position, improves the operation efficiency, and facilitates the operation.
