Problems solved by technology

[0003] However, before using the puncture hole fascia closure device, it is necessary to remove the puncture device first, but this is prone to pneumoperitoneum leakage. When the puncture hole fascia closure device is placed, it is easy to move the tissue layers in the original perforation, making the closed layer Creates misalignment, prolongs wound healing time and quality
Even during the insertion process, a new puncture channel is generated to form a secondary injury, which leads to more serious trauma and increases the difficulty of closure
[0004] Medtronic's VersaOne is a two-in-one product of a trocar poking card and a fascial closure device, which solves the above-mentioned problems of the traditional fascial closure device, but requires additional assembly accessories for operation, increasing the learning curve and operation steps, and relying on The black marking line at the bottom of the poke card jacket uses the doctor's vision to locate the fascia, which increases the difficulty of operation and the positioning accuracy is prone to deviation
The puncture needle angle is too small, resulting in the fascia layer needle exit point is only 5mm away from the incision, too close, easy to cause incision tear and closure failure
[0005] In addition, the company's products can be put into the stab card of the puncture device first, and then pulled out to perform the closing operation. Although the above-mentioned air leakage problem is also solved, after the first puncture hole closing operation is completed and the sutures are placed , it is necessary to put the puncture device into the puncture hole again and put it into the laparoscopic lens for other puncture hole closure observation assistance, so that the above-mentioned secondary damage problem occurs

Embodiment 2

[0056] The difference between the structure of the fascial closure device with the trocar poking channel function of this embodiment and the first embodiment is that a trocar fixing disc 32 is added. like Figure 15 As shown, a fixed disc 32 is added outside the body to cover the rubber disc outside the trocar rod to prevent the trocar from moving downward in the body. The fixed disc 32 can move up and down with damping for position adjustment. Cooperating with the positioning and fixing balloon 18, the puncture device can be fully fixed, preventing the fascial closure device with the function of the puncture device from poking the passage from moving up and down.

Embodiment 3

[0058] The difference between the structure of the fascial closure device with the trocar poking channel function of this embodiment and the first embodiment lies in the structure of the front end of the wire grasping forceps. like Figure 16 As shown, the front end structure of the wire grasping pliers provided in this embodiment is in the shape of a symmetrical hook, and the cross-sectional shape is rectangular or circular. like Figure 17 As shown, the front end structure of the thread grasping forceps can also be replaced by: thread setting hook groove 35, which has no grasping function and can only hook sutures, and its cross-sectional shape is circular.

Embodiment 4

[0060] The difference between the structure of the fascial closure device with the function of piercing the passage in this embodiment and the first embodiment is that, as Figure 18 and Figure 19 As shown, the needle exit channel 41 has the same outer diameter as the puncture thread setting needle, and the inner wall of the needle exit channel is inclined downward at 19 degrees, which is consistent with the inclination angle of the puncture thread setting needle. At this time, rubber can not be provided to seal the needle exit.

Abstract

The invention provides a fascia closer with a trocar to establish a pathway function. The fascia closer comprises a puncture outfit rod body with a surgical instrument imbedding hole at an upper end; two puncture needle leading-in columns located on two sides of the puncture outfit rod body; a puncture needle insertion rubber sealing opening formed in a head end of the puncture needle guide-in column; two puncture needle outlet rubber sealing openings located on two sides of a lower portion of the puncture outfit rod body; a positioning and fixing balloon arranged below the puncture outfit rod body; a balloon gas injection valve positioned on one side of the puncture outfit rod body and connected with the positioning and fixing balloon below the puncture outfit rod body; a puncture thread placement needle with a puncture thread placement needle push rod at a tail end, a puncture needle outer tube sleeved with the puncture thread placement needle, a fixed handrail arranged at an upper end of the puncture needle outer tube, a push rod reset spring arranged between the puncture thread placement needle push rod and the fixed handrail, and thread placement nippers arranged at a front end of the puncture thread placement needle. The fascia closer has a puncture function and a fascia closing function at the same time.

Description

technical field [0001] The invention relates to a fascia closure device with the function of piercing a passage with a puncture device, which belongs to the field of medical instruments. Background technique [0002] Surgical laparoscopic surgery has gradually become the current mainstream surgical method. It establishes a puncture hole through an incision of 5-10 mm, and inserts a trocar to poke a card to establish a passage. The surgeon can insert the endoscopic lens and cavity through the trocar. Mirror surgery instruments. At the end of the operation, after the puncture device is pulled out and stuck, the puncture hole needs to be closed. Generally, sutures are used for direct suture or a puncture hole fascia closer. The puncture hole fascia closer is easier to close the fascia than sutures, and it is firm. Reliable, can reduce the incidence of puncture hernia. [0003] However, before using the puncture hole fascia closure device, it is necessary to remove the punctur...
