Description

Technical Field

[0001] The utility model relates to the technical field of abdominal puncture device processing, in particular to a rivet sleeve assembly device. Background Art

[0002] Laparoscopic surgery has gradually replaced traditional surgery due to its advantages of less trauma, less physiological interference to patients, good cosmetic effect, less pain, and faster recovery. It has been widely used in general surgery, gynecology, and cardiothoracic surgery. Laparoscopic surgery requires opening an incision in the patient's abdomen and performing the surgery under laparoscope observation. Fascia suture is required after the surgery.

[0003] At present, most of the above operations are performed with abdominal puncture devices. For example, the Chinese invention patent with patent application number CN202111344054.6 discloses a push-pin suturing structure for a laparoscopic puncture suturing device, the Chinese invention patent with patent application number CN201480057286.5 for trocar and wound closure device, and the Chinese utility model with application number CN202320262674.3 discloses a fascia suturing puncture device. All of them are based on the original abdominal puncture device, and a mechanism for suturing the wound is added. After the operation is completed, the patient's wound can be quickly sutured, which can achieve rapid suturing of the wound. Among them, the patent CN202320262674.3 discloses “S1. During the abdominal surgery, first install the anchor with wire on the anchor groove, make an incision in the abdominal cavity with a scalpel, insert the assembled puncture sheath assembly and puncture vertebra assembly into the incision, and pull the puncture device outward so that the puncture vertebra head spurt contacts the abdominal fascia; S2. Press the needle core button, pull up the needle seat, and press the puncture needle core downward with the sound of the shrapnel popping out. When the force is unloaded, the anchor has penetrated the fascia, and under the action of the spring, the shrapnel and the needle rod return to the needle seat;

[0004] S3. Continue to push the puncture device into the body to allow the puncture vertebral head to leave the fascia. Press the buckle to pull out the puncture vertebral assembly, and leave the remaining puncture sheath assembly on the abdominal incision. According to the needs of abdominal surgery, the abdominal cavity can be inflated through the air valve to ensure surgical space. Different surgical instruments can be inserted through the puncture sheath assembly for surgery. After the surgery, the puncture sheath assembly can be directly pulled out. Since the wire anchor is left in the fascia, the suture can be knotted and the fascia can be sutured. The suture and anchor are both absorbable materials in the body, which can effectively solve the problem of fascia suturing. "

[0005] It can be seen from the above-mentioned patent disclosure that when using a puncture device to suture a wound, rivets and sutures need to be installed on the puncture device first. In the prior art, the rivets of some puncture devices are installed before use, and most of them are pre-installed on the puncture device during the production process, which is convenient for direct use when used. At present, when processing puncture devices, most rivet installations are purely manual installations, which is laborious, and during the installation process, the rivets need to be pressed tightly into the rivet grooves, so the operator needs to apply a certain amount of pressure during installation, which can easily cause injuries to the operator due to the sharp parts.

[0006] Based on the above reasons, the utility model provides a rivet sleeve assembly device, which can facilitate processing personnel to quickly install the rivet on the sleeve of the puncture device. Utility Model Content
