Description

Technical Field

[0001] The utility model relates to a puncture suture device, in particular to a long-distance puncture suture device. Background Art

[0002] Laparoscopic surgery is widely used in minimally invasive surgery because of its advantages of less trauma, less pain, and faster recovery. Laparoscopic surgery requires opening a hole in the patient's abdomen. Medical staff insert the laparoscope into the patient's body, observe the patient's internal conditions with the assistance of the laparoscope, and perform surgery. When the surgery is completed, sutures are introduced to suture the wound.

[0003] However, the existing puncture suturing devices have the following problems: some patients are overweight or even obese, so their subcutaneous fat layer is relatively thick. Therefore, when completing the surgical suturing, there is a certain distance between the actual insertion end point of the suture and the ideal insertion end point, which makes it impossible to accurately and effectively suturing the patient's wound, which may cause problems such as bleeding, infection, puncture hole hernia and other problems in the patient's prognosis. The patient may be in pain after the operation, which runs counter to the original intention of minimally invasive surgery. Summary of the invention

[0004] Purpose of the utility model: The purpose of the utility model is to provide a puncture suturing device capable of achieving long-distance puncture and suturing.

[0005] Technical solution: The long-distance puncture suture device described in the utility model includes an outer sleeve rod, an entry puncture suture device for delivering sutures into the patient's skin, and an exit puncture suture device for pulling sutures out of the patient's skin. The top of the outer sleeve rod is symmetrically provided with an upper needle entry channel and an upper needle exit channel, and the lower needle entry hole and the lower needle exit hole are respectively provided on both sides of the middle and lower part of the outer sleeve rod. The position of the upper needle entry channel corresponds to the position of the lower needle entry hole, and the position of the upper needle exit channel corresponds to the position of the lower needle exit hole; flexible fillers are respectively provided in the upper needle entry channel and the upper needle exit channel. The upper needle entry channel is used for the entry puncture suture device to carry the sutures into the outer sleeve rod, and the upper needle exit channel is used for the exit puncture suture device to carry the sutures out of the outer sleeve rod. The flexible fillers are respectively provided in the upper needle entry channel and the upper needle exit channel to ensure the sealing of the space inside the outer sleeve before suturing the wound, so as to prevent microorganisms from entering the patient's skin through the outer sleeve rod and causing surgical complications.

[0006] Furthermore, the lower needle inlet hole and the lower needle outlet hole are waist-shaped holes. The lower needle inlet hole and the lower needle outlet hole are waist-shaped holes to prevent interference with the obliquely inserted inlet puncture suture device or outlet puncture suture device.

[0007] Furthermore, an air bag is provided at the bottom of the outer sleeve rod, and two notches are symmetrically provided on the air bag, and the notches are used for the inlet suture passer or the outlet suture passer to pass through, and a trachea is provided at the entrance of the air bag. The air bag is used to fix the bottom end of the utility model under the patient's skin after inflation to prevent the puncture suturer from withdrawing from the patient's opening during surgery. Since the insertion point of the suture passer is moved up to the top of the puncture rod, the angle between the suture passer and the central axis of the puncture rod becomes smaller, and the suture passer may interfere with the air bag and puncture the air bag, so the notch provided for the suture passer to pass through can prevent the air bag from being punctured.

[0008] Furthermore, an inflation port for connecting to an external air source is provided on the outer sleeve, and the inflation port is communicated with the inner cavity of the fixed airbag through an air tube.

[0009] Furthermore, it also includes a guide block, which is detachably connected to the top of the outer rod, and has an inlet guide groove and an outlet guide groove, the position of the inlet guide groove corresponds to the position of the upper needle inlet channel, and the position of the outlet guide groove corresponds to the position of the upper needle outlet channel. The guide block is used to assist the inlet suture passer to enter and the outlet suture passer to pass out, so that medical staff can operate more conveniently and quickly.

[0010] Furthermore, it also includes an adapter block, which is detachably connected to the top of the outer rod. The adapter block is used to assist other surgical instruments in combining with the outer rod to achieve different functions during the operation. For example, after the auxiliary puncture rod is combined with the outer rod, it can be accurately inserted into the patient's skin.

[0011] Furthermore, a rubber sleeve is provided on the outer circumference of the outer sleeve rod, and the position of the rubber sleeve corresponds to the position of the lower inlet needle hole and the lower outlet needle hole.

[0012] Beneficial effects: Compared with the prior art, the utility model has the following advantages: 1. The upper needle entry channel and the upper needle exit channel of the utility model are arranged at the top end of the outer sleeve rod, so the relative distance between the upper needle entry channel and the lower needle entry hole (or the upper needle exit channel and the lower needle exit hole) is longer, which can better penetrate the thick subcutaneous fat layer and achieve accurate and effective suturing of the patient's wound; 2. Flexible fillers are respectively arranged in the upper needle entry channel and the upper needle exit channel to ensure the sealing of the space inside the outer sleeve before suturing the wound, so as to prevent microorganisms from entering the patient's skin through the outer sleeve rod and causing surgical complications; 3. Since the upper needle entry channel and the upper needle exit channel are arranged at the top end of the outer sleeve rod, the angle between the incoming thread puncture suture device or the outgoing thread puncture suture device and the central axis of the outer sleeve rod is smaller. In order to prevent the incoming thread puncture suture device or the outgoing thread puncture suture device from piercing the airbag, a notch is respectively arranged on both sides of the airbag, so that the wound can be better sutured.
