Description

Technical Field

[0001] The utility model relates to the technical field of surgical instruments, in particular to a puncture device with a suturing function. Background Art

[0002] Minimally invasive surgery has been around for more than a decade and has been widely used in the medical field. Minimally invasive surgery has the advantages of less trauma, less pain, and faster recovery. Many open surgeries in the past have now been replaced by endoscopic surgeries. Minimally invasive surgery has been greatly developed and expanded, and laparoscopic surgery has been accepted by more and more doctors and patients. Laparoscopic surgery requires a puncture to establish a working channel on the abdominal wall, and surgical instruments perform surgery on patients through the working channel. After laparoscopic surgery, the puncture hole is usually closed by the doctor's hand sewing or using a closure device. The former requires the doctor's time and energy, and the latter will increase the patient's surgical expenses and increase the cost of surgery.

[0003] In a patent application for a puncture device with a suturing function with patent application number CN211156120U, the puncture device includes a puncture device, a sliding side wing, a puncture needle and a poker. A cavity is arranged inside the puncture device, a puncture end is arranged at the bottom of the puncture device, slide grooves are arranged on the left and right sides of the top of the puncture device, port puncture holes are arranged at the bottom of the left and right sides of the puncture end, silicone plugs are filled inside the port puncture holes, sliding side wings are installed on the slide grooves, side wing puncture holes are arranged on the sliding side wings, a puncture needle is arranged between the port puncture hole and the side wing puncture hole, and a lead hole is arranged at the bottom of the puncture needle.

[0004] The device solves the problem that the doctor needs to sew the existing puncture hole by hand when closing it. However, the existing device also has certain problems when in use. The puncture needle fixes the lead wire in the silicone plug by passing the lead wire through the puncture hole. When the doctor pulls out the puncture needle, the puncture needle will bring the lead wire out of the silicone plug together, thereby affecting the puncture effect. In addition, when the puncture device is punctured and pulled out, medical staff need to perform two operations, wasting staff time. Summary of the invention

[0005] The existing puncture device with suturing function fixes the lead wire in the silicone plug through the puncture needle by setting a lead wire hole at the front end of the puncture needle. When the doctor pulls out the puncture needle from the silicone plug, the lead wire in the puncture needle will be pulled out together. Moreover, when the existing puncture device is used for puncture, the staff needs to insert the puncture device into the abdominal cavity first, and then insert the lead wire into the silicone plug of the puncture device before pulling out the puncture device, which wastes the staff's time and reduces the efficiency of the operation.

[0006] In order to overcome the problems existing in the prior art, the utility model provides a new technical idea. By arranging an independent needle at the front end of the suture lead needle, when the suture lead needle is inserted into the silicone plug, the independent needle on the suture lead needle will be separated from the suture lead needle and embedded in the silicone plug, thereby bringing the lead out through the silicone plug, avoiding the situation where the lead falls off. At the same time, an elastic lead rod that can automatically pull out the lead is additionally arranged inside the puncture device, saving time for medical staff.

[0007] The above technical objectives of the utility model are achieved through the following technical solutions:

[0008] A puncture device with suturing function comprises a puncture device and a punch, wherein the puncture device is arranged outside the punch, and is characterized in that it also comprises a suture guide needle for pulling the suture thread and an elastic guide rod for bringing out the guide thread, wherein the elastic guide rod is arranged inside the punch, and the suture guide needle is arranged on both sides of the puncture device.

[0009] A cavity is provided inside the puncture device, a side wing is provided at the top of the puncture device, and side wing puncture holes are provided on the side wings. A puncture end is provided at the bottom of the puncture device, and port puncture holes are provided on the left and right sides of the puncture end. The puncture device is provided inside the cavity.

[0010] Furthermore, a second cavity is provided inside the poker, and port puncture holes are provided on the left and right sides of the bottom end of the poker, and the elastic lead rod is provided in the second cavity.

[0011] The elastic lead rod comprises a spring and a pressing rod, the spring is sleeved on the top end of the pressing rod, and a silicone plug is arranged on the bottom end of the pressing rod.

[0012] Preferably, the suture guide needle is arranged between the port puncture hole and the wing puncture hole, and the suture guide needle comprises a puncture needle handle and a guide needle head, and the guide needle head is sleeved on the puncture needle handle.

[0013] Compared with the prior art, the beneficial effects of the utility model are embodied in:

[0014] By additionally providing a lead needle head on the puncture needle, that is, by setting a suture lead needle, when the lead is sent into the silicone plug through the puncture needle, the lead needle head can combine with the silicone plug together with the lead, avoiding the problem of the lead in the silicone plug being brought out when the lead needle is withdrawn from the silicone plug. At the same time, by providing an elastic lead rod, after the staff presses the elastic lead rod, the elastic lead rod can automatically pop out to bring the lead in the silicone plug out, and the staff does not need to manually pull out the puncture device, which saves the staff's physical strength and time, and also improves the doctor's work efficiency.
