A fixed stamp card

Abstract

The utility model belongs to the technical field of medical devices, and specifically relates to a fixable puncture card. The puncture card is also called a puncture device, which is mainly used to penetrate the entire layer of the abdominal wall during laparoscopic surgery, establish a channel between the outside world and the abdominal cavity, and allow surgical instruments to enter the abdominal cavity through the puncture device cannula to complete the surgical process. Compared with traditional laparoscopic surgery, it has the advantages of small surgical wounds and reduced patient pain. However, ordinary puncture cards are only fixed by abdominal wall muscles, and the fixation effect is not good. Once displacement occurs, it will affect the progress of the operation and even hurt the patient. The utility model proposes a fixable puncture card, which is provided with a rubber pad, a cylindrical first airbag and an umbrella-shaped second airbag on the puncture sleeve, and by injecting air into the airbag, the airbag bulges and fits tightly against the abdominal wall muscles, thereby fixing the puncture card, improving the safety of the operation, and playing a role in closing the incision after the operation.

Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a fixable stamping card. Background Art

[0002] The puncture card, also known as the trocar, is mainly used to penetrate the entire layer of the abdominal wall during laparoscopic surgery, establish a channel between the outside world and the abdominal cavity, and allow surgical instruments to enter the abdominal cavity through the trocar cannula to complete the surgical process. Compared with traditional laparoscopic surgery, the use of disposable puncture cards for laparoscopic surgery has the characteristics of reducing intraoperative incisions, reducing postoperative pain, less trauma, and faster recovery, which is more in line with the concept of minimally invasive surgery.

[0003] The puncture device consists of a puncture cannula and a puncture core. The main task of the puncture core is to penetrate the entire abdominal wall together with the puncture cannula and leave the puncture cannula on the abdominal wall. The main task of the puncture cannula is to allow various surgical instruments to pass into the abdominal cavity so that the doctor can perform the operation and complete the surgical task.

[0004] Traditional poking cards are mainly fixed by abdominal wall muscles and have no fixed design. During the operation, if the position of the poking card changes, it will not only affect the operation process, but also may harm the patient. At the same time, after the pathology is removed, the pathological incision is difficult to close and the pneumoperitoneum environment is difficult to maintain. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a fixable poking card, which reduces the possibility of displacement of the poking card and improves the safety and stability of the operation.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme, including a puncture sleeve and a puncture core arranged in the puncture sleeve, one end of the puncture sleeve is a puncture end, and the other end is a sealing end, the puncture sleeve puncture end is inclined, the sealing end of the puncture sleeve is connected to a sealing cap, the sealing end, middle part and puncture end of the puncture sleeve are respectively provided with a rubber pad, a first airbag and a second airbag, the sealing end of the puncture sleeve is provided with an inflation joint, the inflation joint is respectively connected to the first airbag and the second airbag through a trachea arranged inside the puncture sleeve 1, and a switch valve is provided at the inflation joint.

[0007] As a preferred solution of the utility model, the first airbag is cylindrical, and the side surface of the first airbag is provided with folds that stretch along the axial direction after being inflated, and the second airbag is umbrella-shaped.

[0008] As another preferred embodiment of the present invention, the outer wall of the puncture sleeve is provided with an external thread, and the inner side of the rubber pad is provided with an internal thread matching the puncture sleeve.

[0009] Beneficial effects of the utility model:

[0010] The utility model solves the problem that ordinary puncture cards are only fixed by abdominal wall muscles and may shift, and proposes a fixable puncture card. A rubber pad and two air bags of different shapes are arranged on the outside of the puncture sleeve. After the air bags are inflated, the air bags swell and cling to the abdominal wall muscles, so that the puncture card is more firmly fixed, and the utility model can also play the role of closing the incision. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a schematic diagram of the overall structure of the utility model.

[0012] In the accompanying drawings, 1 is a puncture sleeve, 2 is a sealing cap, 3 is a rubber pad, 4 is a first air bag, 5 is a second air bag, 6 is an inflation connector, and 7 is a switch valve. DETAILED DESCRIPTION

[0013] The utility model adopts the following technical solutions: Figure 1 As shown, it includes a puncture sleeve 1 and a puncture core arranged in the puncture sleeve, one end of the puncture sleeve 1 is a puncture end, and the other end is a sealing end, the puncture sleeve 1 The puncture end is tilted, and the sealing end of the puncture sleeve 1 is connected with a sealing cap 2, and the sealing end, the middle part and the puncture end of the puncture sleeve 1 are respectively provided with a rubber pad 3, a first air bag 4 and a second air bag 5, and the sealing end of the puncture sleeve 1 is provided with an inflation joint 6, and the inflation joint 6 is respectively connected with the first air bag 4 and the second air bag 5 through an air tube arranged inside the puncture sleeve 1, and a switch valve 7 is provided at the inflation joint 6.

[0014] As a preferred solution of the utility model, the rubber pad 3 is annular, the first airbag 4 is cylindrical, and the side of the first airbag 4 is provided with folds that will stretch axially after inflation. After inflation, the first airbag 4 will expand axially and radially, and the second airbag 5 is umbrella-shaped.

[0015] As another preferred embodiment of the present invention, the outer wall of the puncture sleeve 1 is provided with an external thread, and the inner side of the rubber pad 3 is provided with an internal thread matching the puncture sleeve 1 , and the position of the rubber pad 3 can be adjusted by the thread.

[0016] When using the utility model, the switch valve 7 is opened, and air is injected into the first airbag 4 and the second airbag 5 through the inflation joint 6. The two airbags gradually swell up and cling to the patient's abdominal wall muscles. The switch valve 7 is closed, and the puncture sleeve 1 is fixed at the abdominal incision. The utility model can also play the role of closing the incision.

[0017] It can be understood that the above specific description of the utility model is only used to illustrate the utility model and is not limited to the technical solution described in the embodiments of the utility model. Ordinary technicians in the field should understand that the utility model can still be modified or replaced by equivalents to achieve the same technical effect; as long as the use requirements are met, they are within the protection scope of the utility model.
