Description

Technical Field

[0001] The utility model relates to a medical surgical instrument, in particular to a laparoscope incision sealing device with a puncture device sleeve. Background Art

[0002] In laparoscopic-assisted small abdominal incision surgery, incision protectors are often used to effectively open and reasonably protect the abdominal incision. Existing incision protectors widely used in surgical operations include internal clamps, external clamps and elastic tubes, and the internal clamps and external clamps are respectively arranged at both ends of the elastic tube. During the operation, when the extracorporeal operation is completed and it is necessary to establish pneumoperitoneum again and insert the laparoscope, the following two methods are usually selected according to the surgeon's habits to temporarily close the abdominal incision; the first method is to use multiple towel clamps to temporarily clamp and reduce the abdominal incision and insert the puncture cannula, but the towel clamps often cause multiple abdominal wall tissues to be clamped when the incision is closed, and the free movement of other instrument arms will be affected due to the large number of abdominal wall instruments; the second method is to use rubber gloves to temporarily make the sealing membrane of the incision protector, but rubber gloves are more elastic and lack support, which makes it difficult to control the position of the laparoscope after insertion, and it is difficult to stabilize the surgical field of view.

[0003] Therefore, there is an urgent need for a laparoscopic incision sealing device with a built-in puncture sleeve to solve the problem of closing the abdominal wall incision during laparoscopic-assisted small abdominal wall incision surgery. Utility Model Content

Thus, the cross-shaped incision of the elastic air blocking sealing sheet can be used for inserting instruments, and after the instruments are withdrawn, they can be naturally restored to a certain degree of sealing.

[0032] The sleeve assembly 1 further includes a guide cover 1-1 and a sealing cap 1-2. The sealing cap 1-2 is installed on the inner wall of the outer ring of the air blocking valve. The sealing cap 1-2 is located above the elastic air blocking sealing sheet, and the lower end of the sealing cap 1-2 is a constriction. The constriction of the sealing cap 1-2 can be used for instrument insertion. The upper end of the sealing cap 1-2 is fixedly connected to the upper end of the sleeve base 1-5 through the guide cover 1-1. In this way, the carbon dioxide gas injected into the abdominal cavity can be further sealed by the setting of the sealing cap 1-2. At the same time, the constriction setting of the lower end of the sealing cap 1-2 can help guide the inserted instrument.

[0033] The inner side of the guide cover 1-1 is provided with a guide channel connected with the inner side of the sealing cap 1-2, and the upper end of the guide channel is provided with an upward flared shape.

[0037] The device of the utility model has a one-way sleeve assembly 1 and an incision sealing sleeve 3 that are integrally formed and have a corresponding gas injection passage and a switch, thereby ensuring the normal use of the device. At the same time, through the elastic expansion and contraction of the retractable silicone membrane 3-2 and the elastic fixing ring 3-1, it can be used in conjunction with an incision protector, which is convenient for installation and removal, thereby providing a strong guarantee for the simplicity, convenience, stability and reliability of intraoperative operation.

[0038] During laparoscopic-assisted small abdominal wall incision surgery, an incision protector is often used to effectively open and reasonably protect the abdominal wall incision. The existing incision protector widely used in surgical operations includes an inner clamp, an outer clamp and an elastic tube, and the inner clamp and the outer clamp are respectively arranged at both ends of the elastic tube. When the in vitro operation part is completed and it is necessary to re-establish pneumoperitoneum and insert a laparoscope, by putting the incision sealing sleeve 3 of the device on the outer clamp of the incision protector, the airtightness of the abdominal cavity when re-establishing pneumoperitoneum can be well guaranteed, and the carbon dioxide gas injected into the abdominal cavity can be prevented from leaking out, and a channel for laparoscope insertion can be provided through the one-way sleeve assembly 1. Compared with the existing intraoperative temporary abdominal closure method using towel clamps and rubber gloves, the device has the advantages of simple operation, stability and reliability, etc., which provides a good guarantee for the rapid progress of the operation. Its advantages of simple and reliable structure and convenient operation have solved the existing problems well.
