Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a guiding component for a fascia suture puncture device and a fascia suture puncture device. Background Technique

[0002] In recent years, with the wide application of laparoscopic surgery, postoperative suture has become a major problem. Compared with open surgery, the abdominal wall complication rate of laparoscopic surgery has decreased significantly. The abdominal wall complications of open surgery account for about 50% of the complications. Laparoscopic surgery not only has a low incidence rate, but also has a relatively mild degree. In clinical laparoscopic minimally invasive surgery, it is usually necessary to establish a surgical channel for entering and exiting the abdominal cavity from the outside, manipulate surgical instruments outside the abdominal cavity, and perform operations such as exploring, electrocoagulating, hemostasis, tissue separation and incision, and suture on the diseased tissue through the channel. At the same time, the wound should be sutured as soon as possible after the operation to ensure a better suture effect and reduce the risks of wound infection, lesion, hernia, etc.

[0003] The commonly used devices in traditional laparoscopic surgery are puncture devices and suture devices. During the operation, after the puncture device completes the puncture and the internal abdominal cavity operation is finished, the puncture device needs to be taken out, and then the suture device is used for suture. The conversion of devices in the middle is particularly likely to cause patient infection and also affects the work efficiency of medical staff. It not only prolongs the operation time but also increases the pain of the patient. Therefore, a fascia suture puncture device with dual functions of puncture and suture has gradually become popular in laparoscopic surgery. It can not only greatly improve the operation efficiency of doctors in laparoscopic surgery but also avoid the conversion of devices in the middle, effectively reducing the pain of the patient.

[0004] Such as Figure 1A fascia suture puncture device of a traditional structure is shown, comprising a puncture sheath A, a puncture needle B and an introducer C, wherein the upper end of the puncture needle B is provided with a puncture needle seat B-1, and the lower end is provided with a puncture needle head B-2, and the left and right sides of the puncture needle B are provided with two oblique holes B-3 for inserting the introducer C respectively, and the two oblique holes B-3 are obliquely staggered; the puncture sheath A comprises a sheath tube A-1, the upper end of the sheath tube A-1 is provided with a sheath tube seat A-2 and a sealing cover A-3, the sheath tube A-1 is provided with a guide window A-1a corresponding to the two ends of the oblique hole B-3, the front side wall of the sheath tube seat A-2 is provided with a U-shaped groove plate A-2a which penetrates its internal cavity, and the outer side wall of the sheath tube seat A-2 A pair of process ears A-5 are provided on the surface on the left and right sides, and a steam injection valve A-4 is provided at the upper end of the sheath seat A-2, which passes through the U-shaped groove plate A-2a and extends to the outside. The puncture needle B-2 at the lower end of the puncture needle B passes through the sealing cover A-3, the sheath seat A-2 and the puncture sheath A in sequence and extends to the outside of the lower end of the puncture sheath A; the introducer C includes a cylindrical body C-1, and a needle tube C-2 is provided at the lower end of the cylindrical body C-1. The outer side surface of the cylindrical body C-1 has a positioning surface C-1a. When in use, the needle tube C-2 is connected to the corresponding guide window A-1a and the inclined hole B-3 on the sheath A-1 and the puncture needle B, and the positioning surface C-1a of the cylindrical body C-1 faces upward. The problem with the fascia suture puncture device of this structure is that there is no guide assembly for guiding the introducer on the puncture sheath, which makes it difficult for the introducer to pass through the corresponding guide window and oblique hole on the sheath tube and the puncture needle, and it is easy to sway, which increases the difficulty of the operation and may cause the hidden danger of unsatisfactory suturing effect; in addition, if a new fascia suture puncture device with a guide function needs to be redesigned, it is bound to be necessary to re-mold, which will invisibly increase the production cost and cause waste of resources of the old mold equipment. For this reason, the utility model proposes a guide assembly for a fascia suture puncture device and a fascia suture puncture device, in order to solve the above technical problems. Summary of the invention

[0005] The purpose of the present utility model is to overcome the defects existing in the prior art and provide a guiding assembly for a fascia suture puncture device and a fascia suture puncture device. When the guiding assembly is in use, it is directly sleeved and fixed at the bottom of the sheath tube seat of a traditional fascia suture puncture device, and the guiding inclined holes on the left and right ear blocks correspond one by one to the two inclined holes on the puncture needle. Thus, the needle tube of the guide can be accurately inserted into the corresponding guiding window and inclined hole directly through the guiding inclined holes on the ear blocks, significantly reducing the difficulty and error of inserting the needle tube of the guide into the inclined hole on the corresponding puncture needle. Moreover, the guiding inclined holes on the ear blocks play a limiting role on the cylindrical main body of the guide, preventing the guide from swaying when inserted into the inclined hole inside the puncture needle, improving the insertion stability of the guide, and contributing to improving the suture accuracy and safety. It has good implant adaptability with the fascia suture puncture device with a traditional structure, avoiding the need to re-open the mold to design a new fascia suture puncture device with a guiding guide, helping to save costs and having good economic practicality. The overall structure design is simple, convenient to install and use, and has strong practicability. The fascia suture puncture device of the present utility model, by installing the above-mentioned guiding assembly, has the function of guiding the guide during use, significantly reducing the difficulty of inserting the suture thread and contributing to improving the overall progress of the surgical operation.

The left and right sides of the bottom of the mounting seat are respectively clamped on the corresponding process ears on the fascia suture puncture device through a pair of buckles, significantly improving the installation stability of the guiding component of the present utility model on the sheath tube seat, thus ensuring that the assembled fascia suture puncture device has good stability.

[0010] A further preferred technical solution is that an arc-shaped groove is provided on the upper end surface of the bottom of the mounting seat and is located in front of the central through hole. When in use, the sheath tube seat of the fascia suture puncture device is embedded and fixed in the mounting groove of the mounting seat, and the bottom of the U-shaped groove plate of the fascia suture puncture device is embedded in the arc-shaped groove. The bottom of the U-shaped groove plate of the fascia suture puncture device is embedded in the arc-shaped groove at the bottom of the mounting seat, further improving the installation stability of the guiding component of the present utility model on the sheath tube seat.
