Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to an abdominal wall puncture suture device with a guide hole device. Background Art

[0002] Minimally invasive laparoscopic surgery on the human body has the advantages of less trauma, less physiological interference to patients, good cosmetic effect, less pain, and faster recovery. It has gradually replaced traditional surgery and has been widely used in general surgery, gynecology, and cardiothoracic surgery. Laparoscopic surgery requires opening a hole in the patient's abdomen and performing the operation under laparoscopic observation. Fascia suture is required after the operation. Fascia suture is difficult to operate due to the small incision and deep inner wall. The current solutions include manual suturing and fascia suturer suturing. Manual suturing is suitable for thin patients. For obese patients, the abdominal wall tissue is thick and cannot meet the requirements of accurate and effective suturing of the puncture incision, leading to a series of complications, such as bleeding, infection, puncture cannula guide hole hernia and injury. Fascia suturer suturing can suture the fascia of obese patients, but the puncture device must be pulled out first, and then the fascia suturer is operated. The operation is complicated and the operation time is long, which increases the risk of infection for patients.

[0003] The existing fascia suture devices and puncture suture devices are not perfect in structure and are not convenient to use. Summary of the invention

[0004] The purpose of the present invention is to provide an abdominal wall puncture suture device with a guide hole device in view of the deficiencies of the prior art.

[0021] Preferably, the suture clamp is composed of two elastically bent steel wires. When extended, the suture clamp opens the clamp due to its own bending; when reset, the suture clamp closes the clamp due to the limitation of the needle tube wall, thereby achieving the function of clamping the suture.

[0022] Compared with the prior art, the abdominal wall puncture suture device with a guide hole device of the present invention has the following beneficial effects: Advantages: 1. The abdominal wall puncture suture device with a guide hole device makes it easier for the threading hook to align the angle for needle insertion, making it convenient to place the sutures on both sides of the abdominal wall incision.

[0023] 2. A rounded transition is used at the entrance of the guide hole. Even if the threading hook is not aligned with the guide hole and falls near the guide hole, the threading hook can slide into the guide hole, reducing the operator's operating fatigue.

[0024] 3. The guide hole device is set to be flat and extends outward, which is convenient for clamping or holding when in use.

[0025] 4. The left and right guide holes are set at a position biased to the outside, which increases the angle between the threading hook and the abdominal wall puncture suture device, appropriately increases the suture area, increases the firmness of the suture, and reduces the risk of loose suture at the abdominal wall due to too small a suture area.

[0026] 5. Hollow auxiliary fixing holes are arranged on the inner sides of the left guide hole and the right guide hole, so as to facilitate the use as a channel during the operation and to prevent the body of the fixator from shaking when the abdominal wall is sutured.

[0027] The abdominal wall puncture suture device with a guide hole device of the present invention is reasonably designed and easy to use. Due to the provision of a puncture sleeve device, a guide hole device, a puncture cone device and a threading hook, the puncture of deep fascia of the abdominal cavity, thoracic cavity and the like can be achieved under laparoscope, and at the same time, a channel for other minimally invasive instruments to enter the body is established for laparoscopic surgery, a method for pre-tying sutures is provided, and the sutures on both sides of the incision can be pulled out of the puncture sleeve and knotted, without affecting the intraoperative operation.

[0028] An abdominal wall puncture suturing device with a guide hole device is used for puncturing the abdominal cavity, thoracic cavity and other tissues during laparoscopic examination and surgery, establishing a working channel for abdominal and thoracic surgery, allowing surgical instruments to enter the abdominal cavity, thoracic cavity and other parts through the puncture cannula, thereby completing the surgical process. After the operation is completed, deep fascia sutures can be conveniently performed, truly realizing minimally invasive surgery. BRIEF DESCRIPTION OF THE DRAWINGS
