Flexible silica gel flip puncture outfit

Abstract

The invention relates to a flexible silica gel flip puncture outfit. At present, puncture outfits with good performance do not exist. The flexible silica gel flip puncture outfit comprises a puncture tube, a puncture base, a seal base, a puncture tube base, a seal ring, a flexible seal cap and a puncture needle, and is characterized by also comprising a silica gel flip seal base device, wherein the silica gel flip seal base device consists of a flexible silica gel pad and a ceramic anti-scratch base; the flexible silica gel pad consists of a flexible silica gel pad outer ring, a connecting block and a flexible silica gel pad inner ring; the flexible silica gel pad inner ring is connected with the flexible silica gel pad outer ring through the connecting block; the ceramic anti-scratch base is clamped in the flexible silica gel pad inner ring; the flexible silica gel pad outer ring is clamped in a clamping groove on the inner wall at the other end of the puncture base; the ceramic anti-scratch base is matched with one end of the seal base; the puncture needle is inserted in an operating channel; and a puncture cap is matched with the flexible seal cap. The flexible silica gel flip puncture outfit has a reasonable structural design, is easy to operate, has good sealing effect, long service life and safe and reliable performance, and is special for surgical equipment to insert into a human body.

Description

technical field [0001] The invention relates to a soft silicone flap puncture device, in particular to a soft silicone flap puncture device specially used for surgical instrument channels, which is an operation channel specially used for surgical instruments to penetrate into the human body, and belongs to minimally invasive laparoscopy. Medical surgical instruments. Background technique [0002] In minimally invasive laparoscopic medical surgery in the human body, once a lesion is found in the human body, surgery is required. During the operation, surgical instruments need a special operation channel to enter the human body to make the operation go smoothly. The operation channel is usually provided by a trocar. supply. In the prior art, there are different types of puncture devices used for surgical instrument channels, but the sealing devices of these puncture devices are different. Some use the action of springs to form a metal clamshell type sealing structure, and some...

AI Technical Summary

Problems solved by technology

The existing puncture device has the following defects: during the application of the operation channel, due to the pneumoperitoneum effect, the residual liquid of the human body and other liquids required for the operation will enter the channel, and the metal clamshell seal structure formed by the spring action , because the spring is small and thin, it is easy to be oxidized and deformed, which affects the sealing effect of the channel; in the metal sphere type sealing structure formed by magnetic action, due to the suction seal between the magnetic metal and the metal sphere, it is easy to cause suction deviation to affect the channel. sealing effect

Although the disposable puncture device has a good sealing effect, its structure is complicated, the production cost is high, and it is relatively inconvenient to use

Another example is that the publication date is September 29, 2010, and the publication number is CN101843516A Chinese patent, which discloses a disposable multifunctional puncture device, which is composed of a puncture needle assembly and a puncture seat assembly. The seat assembly is provided with a sealing cover assembly and a converter assembly, and the puncture needle assembly is inserted into the puncture seat assembly, wherein the sealing cover in the sealing cover assembly is connected to the sealing cover seat, so that the sealing cover is easily scratched by the puncture needle assembly, Thus affecting the operation effect, and the structure of the sealing cover assembly is relatively complicated, and the operation is relatively inconvenient, and the puncture device is a disposable puncture device, and the use cost is relatively high, which not only increases the burden on the patient, but also causes a waste of resources

[0004] To sum up, there is no clamshell puncture device with a simple structure, good sealing effect, and an ideal sealing effect, which is specially used for surgical instruments to penetrate into the operation channel of the human body.
